The present invention relates to diesel hammers for pile driving and, in particular, to guide systems and methods that simplify the process of adapting a diesel hammer to different support structures having different geometries.
A diesel hammer is a pile driver having a housing and a ram. The ram is forced up by diesel combustion and falls within the housing to impact a pile and drive the pile into the earth. Conventionally, a support system supports the diesel hammer above the pile as the ram is driving the pile such that the driving force is applied along the axis of the pile. As the diesel hammer drives the pile, the support system interacts with a guide system that guides the diesel hammer such that a housing thereof moves with the pile along the pile axis.
Support systems for the diesel hammer come in a variety of configurations. Conventionally, the guide system for the diesel hammer is modified to adapt to a particular diesel hammer to a particular configuration of support system.
The need exists for a guide systems and methods for diesel hammers that may be easily reconfigured to allow a particular support system to accommodate a particular diesel hammer.
The present invention may be embodied as a guide system for allowing a diesel hammer to be supported by a plurality of support systems comprising a primary channel system and a pair of first channel adapter assemblies. The primary channel system is rigidly connected to the diesel hammer to define a pair of primary channels and a primary spacing distance between the primary channels. Each of the pair of first channel adapter assemblies defines a first secondary channel. The guide system operates in a first configuration and in a second configuration. In the first configuration, portions of a first support system of the plurality of support systems are received within the primary channels. In the second configuration, each of the first channel adapter assemblies is detachably attached to the primary channel system such that the first channel adapter assemblies define a first secondary spacing distance between the first secondary channels, the first secondary spacing distance is different from the primary spacing distance, and portions of a second support system of the plurality of support systems are received within the first secondary channels.
The present invention may also be embodied as a method of supporting a diesel hammer from a plurality of support systems comprising the following steps. A primary channel system is rigidly connected to the diesel hammer to define a pair of primary channels and a primary spacing distance between the primary channels. A pair of first channel adapter assemblies is provided, and each first channel adapter assembly defines a first secondary channel. In a first configuration, portions of a first support system of the plurality of support systems are received within the primary channels. In a second configuration, each of the first channel adapter assemblies is detachably attached to the primary channel system such that the first channel adapter assemblies define a first secondary spacing distance between the first secondary channels, the first secondary spacing distance is different from the primary spacing distance, and portions of a second support system of the plurality of support systems are received within the first secondary channels.
The present invention may also be embodied as a guide system for allowing a diesel hammer to be supported by first, second, and third support systems. The guide system comprises a primary channel system, a pair of first channel adapter assemblies, and a pair of second channel adapter assemblies. The primary channel system is rigidly connected to the diesel hammer to define a pair of primary channels and a primary spacing distance between the primary channels. Each of the first channel adapter assemblies defines first secondary channel. Each of the second channel adapter assemblies defines a second secondary channel. The guide system operates in first, second, and third configuration. In the first configuration, portions of the first support system are received within the primary channels. In the second configuration, each of the first secondary channel adapter assemblies is detachably attached to the primary channel system such that the first channel adapter assemblies define a first secondary spacing distance between the first secondary channels, the first secondary spacing distance is different from the primary spacing distance, and portions of the second support system are received within the first secondary channels. In the third configuration, each of the second channel adapter assemblies is detachably attached to the primary channel system such that the second channel adapter assemblies define a second secondary spacing distance between the first secondary channels, the second secondary spacing distance is different from the primary spacing distance and the first secondary spacing distance, and portions of the third support system are received within the second secondary channels.
Referring initially to
A ram (not shown) is supported for up and down movement within the housing 22 during operation of the diesel hammer 20 to drive a pile (not shown). The primary channel system 26 is configured to allow the ram housing 22 to be held in an upright position during pile driving operation but also to allow the ram housing 22 to move down relative to the earth as the pile is driven into the earth.
The example primary channel system 26 comprises a pair of primary guide members 40. The example primary guide members 40 are secured to the ram housing 22 by first mounting brackets 42, second mounting brackets 44, and third mounting brackets 46. During normal use of the example pile driving system 20, the first, second, and third mounting brackets 42, 44, and 46 will be connected to an upper end, a middle portion, and a lower end of the ram housing 22, respectively. Typically, the primary guide members 40 are rigidly connected to the mounting brackets 42, 44, and 46 by welding or the like, while the mounting brackets 42, 44, and 46 are rigidly connected to the ram housing 22 by welding or the like.
The example primary channel system 26 comprises two identical guide members 40, and the guide members 40 and mounting brackets 42, 44, and 46 are symmetrically arranged on opposite sides of the ram housing 22. However, more than two guide members and/or guide members of different dimensions may be used as part of a support system of the present invention.
Each of the example guide members 40 comprises a main guide wall 50, a first side guide wall 52, a second side guide wall 54, and flared surfaces 56 formed on both ends of the side guide walls 52 and 54. Primary mounting holes 60 are formed in the main guide walls 50. The example primary mounting holes 60 are arranged in pairs 62, and the pairs 62 are grouped to define a primary hole pattern 64. The primary channel members 40 define primary channels 70 between the guide walls 50, 52, and 54. Each of the primary channels 70 defines a primary channel width 72 and a primary channel depth 74.
As perhaps best shown in
The first support width 82, first support depth 84, and first support spacing distance 86 will be predetermined for a particular situation. The first support width 82 will determine the primary channel width 72, the first support depth 84 will determine the primary channel depth 74, and the first support spacing distance 86 will determine the primary channel spacing distance 78. In particular, the primary channel width 72 will be slightly larger than the first support width 82, the primary channel depth 74 will be sufficient to engage the first support depth 84 dimensions of the support members 80 to allow the support members 80 to engage the primary channel members 40 to hold the diesel hammer system 20 substantially upright or vertical, and the primary channel spacing distance 78 will be slightly smaller than the first support spacing distance 86.
In use, the support members 80 are sized, dimensioned, and arranged to maintain the diesel hammer system 20 in a substantially upright or vertical orientation during normal operation of the diesel hammer system 20. In particular, the support members 80 will typically be held by a vehicle or crane (not shown) capable of supporting the support members 80 and diesel hammer system 20 in a substantially upright or vertical orientation relative to a desired location at which the pile is to be driven. The vehicle or crane for supporting the support members 80 is or may be conventional and will not be described herein in detail.
Turning now to
In particular, each of the example first and second channel adapter assemblies 124 and 126 comprises a secondary channel member 130, a base member 132, one or more standoff members 134, and at least one bolt assembly 136. The example secondary channel members 130 are identical and each comprises a main guide wall 140, a first side guide wall 142, a second side guide wall 144, and flared surfaces 146 formed on each end of the first and second side guide walls 142 and 144. Secondary mounting holes 150 are formed in the main guide walls 140. The mounting holes 150 are arranged in pairs 152, and the pairs 152 are grouped to define a first secondary hole pattern 154. The example bolt assembly or assemblies 136 each comprises a bolt 156 and a nut 158. The example standoff members 134 rigidly connect the secondary channel member 130 to the base member 132 such that the main guide wall 140 is substantially parallel to a reference plane defined by the base member 132.
The example first and second channel adapter assemblies 124 and 126 further comprise web members 160, first lateral braces 162, second lateral braces 164, third lateral braces 166, first longitudinal braces 170, second longitudinal braces 172, and third longitudinal braces 174. Each web member 160 is rigidly connected to the base member 132 and one or more of the standoff members 134. The example lateral braces 162, 164, and 166 are each rigidly connected to one of the standoff members 134 and the secondary channel member 130. The example longitudinal braces 170, 172, and 174 are rigidly connected to one of the standoff members 134, one of the web members 160, and one of the lateral braces 162, 164, or 166.
As shown in
To form the second diesel hammer system 120, the first and second channel adapter assemblies 124 and 126 are arranged such that the base members 132 thereof are each within one of the primary channels 70 with the secondary mounting holes 150 aligned with the primary mounting holes 60. In particular, the primary hole pattern 64 and secondary hole pattern 154 are sufficiently similar such that the bolts 156 may be inserted through the aligned holes 60 and 150. Rotating the nuts 158 relative to the bolts 156 allows the bolt assemblies 136 to be formed, thereby rigidly connecting the base members 132, and thus the first and second adapter assemblies 124 and 126, to the diesel hammer system 20.
Further, the primary hole pattern 64 and secondary hole pattern 154 are configured such that, when the first and second adapter assemblies 124 and 126 are rigidly connected to the diesel hammer system 20, the secondary channels 180 are substantially aligned with the primary channels 70 and with the ram axis A. The primary channel offset distance 76 and space between the secondary channel members 130 and the base members 132 allow the bolts 156 and nuts 158 to be inserted through the holes 60 and 150 and assembly of the bolt assemblies 136.
With the first and second adapter assemblies 124 and 126 rigidly connected to the diesel hammer system 20, the web members 160 inhibit movement of the secondary channel members 130 along the ram axis or twisting of the secondary channel members 130 relative to the ram axis A. The lateral braces 162, 164, and 166 engage portions of the diesel hammer system 20, in this case the mounting brackets 42, 44, and 46, respectively, to inhibit lateral or tangential movement of the secondary channel members 130 relative to the ram axis A. The longitudinal braces 170, 172, and 174 inhibit movement of the secondary channel members 130 along the ram axis or twisting of the secondary channel members 130 relative to the ram axis A. The longitudinal braces 170, 172, and 174 further inhibit movement of the lateral braces 162, 164, and 166 in a direction generally along the ram axis A.
Further, with the first and second adapter assemblies 124 and 126 rigidly connected to the diesel hammer system 20, the secondary channel members 130 define a secondary channel offset distance 186 from the outer surface of the ram housing 22. And when both of the first and second adapter assemblies 124 and 126 are rigidly connected to the diesel hammer system 20, the secondary channel channels 180 define a secondary channel spacing distance 188.
The second support width 192, second support depth 194, and second support spacing distance 196 will be predetermined for a particular situation. The second support width 192 will determine the secondary channel width 182, the second support depth 194 will determine the secondary channel depth 184, and the second support spacing distance 196 will determine the secondary channel spacing distance 188. In particular, the secondary channel width 182 will be slightly smaller than the second support width 192, the primary channel depth 184 will be sufficient to engage the second support depth 194 dimensions of the support members 190 to allow the support members 190 to engage the primary channel members 130 to hold the diesel hammer system 120 substantially upright or vertical, and the secondary channel spacing distance 188 will be slightly smaller than the second support spacing distance 196.
In use, the support members 190 are sized, dimensioned, and arranged to maintain the diesel hammer system 120 in a substantially upright or vertical orientation during normal operation of the diesel hammer system 120. In particular, the support members 190 will typically be held by a vehicle or crane (not shown) capable of supporting the support members 80 and diesel hammer system 20 in a substantially upright or vertical orientation relative to a desired location at which the pile is to be driven. The vehicle or crane for supporting the support members 80 is or may be conventional and will not be described herein in detail. However, different support systems (e.g., vehicle or crane) may define the second support width 192, the second support depth 194, and the second support spacing distance 196.
The rail adapter system 122 thus allows the diesel hammer system 20 to be converted into the diesel hammer system 120 as appropriate for use with the support members 190 simply by forming the bolt assemblies 136 as described above. The rail adapter system 122 allows the diesel hammer system 120 to be converted back into the diesel hammer system 20 appropriate for use with the support members 80 simply by disassembling the bolt assemblies 136 and removing the first and second channel adapter assemblies 124 and 126.
Each of the example first and second channel adapter assemblies 224 comprises a secondary channel member 230, a base member 232, one or more standoff members 234, and at least one bolt assembly 236. The example secondary channel members 230 are identical and each comprises a main guide wall 240, a first side guide wall 242, and a second side guide wall 244. Secondary mounting holes 250 are formed in the base member 232. The mounting holes 250 are arranged in pairs, and the pairs are grouped to define a secondary hole pattern. The example bolt assembly or assemblies 236 each comprises a bolt 256 and a nut 258. The example standoff members 234 rigidly connect the secondary channel member 230 to the base member 232 such that the main guide wall 240 is substantially parallel to a reference plane defined by the base member 232.
The example first and second channel adapter assemblies 224 further comprise web members 260. While not shown in
To form the third diesel hammer system 220, the first and second channel adapter assemblies 224 are arranged such that the base members 232 thereof are each within one of the primary channels 270 with the secondary mounting holes 250 aligned with primary mounting holes 278 formed in the primary channel members 226 and 228. Rotating the nuts 258 relative to the bolts 256 allows the bolt assemblies 236 to be formed, thereby rigidly connecting the base members 232, and thus the first and second adapter assemblies 224, to the primary channel members 226 and 228, and thus to the diesel ram housing 22.
Each secondary channel member 230 defines a secondary channel 280 defining a secondary channel width 282 and a secondary channel depth 284. Each secondary channel member 230 further defines a secondary channel offset distance 286 when secured relative to the diesel housing 22. Further, when secured relative to the diesel housing 22, the secondary channels 280 define a secondary channel spacing distance.
The rail adapter system 222 thus allows the diesel hammer system 20 with the pairs of L-shaped channel members 226 and 228 to be converted into the diesel hammer system 220 as appropriate for use with support members appropriate for the secondary channel spacing distance simply by forming the bolt assemblies 236 as described above. The rail adapter system 222 allows the diesel hammer system 220 to be converted back into the diesel hammer system 20 appropriate for use with the support members 80 simply by disassembling the bolt assemblies 236 and removing the first and second channel adapter assemblies 224.
Each of the example first and second channel adapter assemblies 324 comprises a secondary channel member 330, a base member 332, and at least one bolt assembly 336. The example secondary channel members 330 are identical and each comprises a main guide wall 340, a first side guide wall 342, and a second side guide wall 344. Main access openings 346 are formed in the main guide wall 340. The example base member 332 is a hollow structure defining a base wall 350, a spaced wall 352, and standoff walls 354. Secondary access openings 356 are formed in the spaced wall 352, while secondary mounting holes 358 are formed in the base wall 350. The mounting holes 358 are arranged in pairs, and the pairs are grouped to define a secondary hole pattern. On each of the access openings 346 and 356 are arranged adjacent to each mounting hole 358. The example bolt assembly or assemblies 336 each comprises a bolt 360 and a nut 362.
To form the fourth diesel hammer system 320, the first and second channel adapter assemblies 324 are arranged such that the base members 332 thereof are each within one of the primary channels 70 with the secondary mounting holes 358 aligned with primary mounting holes 60 formed in the primary channel member 40. The bolts 360 are inserted into the secondary mounting holes 358 by first passing through the access openings 346 and 356. With the bolts 360 in place as shown in
Each secondary channel member 330 defines a secondary channel width 370, a secondary channel depth 372, a secondary channel offset distance 374 when secured relative to the diesel housing 22. Further, when secured relative to the diesel housing 22, the secondary channels 330 define a secondary channel spacing distance.
The rail adapter system 322 thus allows the diesel hammer system 20 to be converted into the diesel hammer system 320 as appropriate for use with support members appropriate for the secondary channel spacing distance defined by the secondary channel members 330 simply by forming the bolt assemblies 336 as described above. The rail adapter system 322 allows the diesel hammer system 320 to be converted back into the diesel hammer system 20 appropriate for use with the support members 80 simply by disassembling the bolt assemblies 336 and removing the first and second channel adapter assemblies 324.
Each of the example first and second channel adapter assemblies 424 comprises a secondary channel member 430, a base member 432, a spacing member 434, and at least one bolt assembly 436. The example secondary channel members 430 are identical and each comprises a main guide wall 440, a first side guide wall 442, and a second side guide wall 444. Main access openings 446 are formed in the main guide wall 440. The spacing member 434 is simply a rigid plate rigidly connected between the secondary channel member 430 and the base member 432 and defines a plate access opening 448. The example base member 432 is a hollow structure defining a base wall 450, a spaced wall 452, and standoff walls 454. Secondary access openings 456 are formed in the spaced wall 452, while secondary mounting holes 458 are formed in the base wall 450. The mounting holes 458 are arranged in pairs, and the pairs are grouped to define a secondary hole pattern. One each of the access openings 446, 448, and 456 are arranged adjacent to each of the mounting holes 458. The example bolt assembly or assemblies 436 each comprises a bolt 460 and a nut 462.
To form the fifth diesel hammer system 420, the first and second channel adapter assemblies 424 are arranged such that the base members 432 thereof are each within one of the primary channels 70 with the secondary mounting holes 458 aligned with primary mounting holes 60 formed in the primary channel member 40. The bolts 460 are inserted into the primary mounting holes 458 by first passing through the access openings 446, 448, and 456. With the bolts 460 in place as shown in
Each secondary channel member 430 defines a secondary channel width 470, a secondary channel depth 472, a secondary channel offset distance 474 when secured relative to the diesel housing 22. Further, when secured relative to the diesel housing 22, the secondary channels 430 define a secondary channel spacing distance.
The rail adapter system 422 thus allows the diesel hammer system 20 to be converted into the diesel hammer system 420 as appropriate for use with support members appropriate for the secondary channel spacing distance defined by the secondary channel members 430 simply by forming the bolt assemblies 436 as described above. The rail adapter system 422 allows the diesel hammer system 420 to be converted back into the diesel hammer system 20 appropriate for use with the support members 80 simply by disassembling the bolt assemblies 436 and removing the first and second channel adapter assemblies 424.
Each of the example first and second channel adapter assemblies 524 comprises a secondary channel member 530, a base member 532, a spacing member 534, and at least one bolt assembly 536. The example secondary channel members 530 are identical and each comprises a main guide wall 540, a first side guide wall 542, and a second side guide wall 544. Main access openings 546 are formed in the main guide wall 540. The spacing member 534 is simply a rigid plate rigidly connected between the secondary channel member 530 and the base member 532 and defines a plate access opening 548. The example base member 532 is a hollow structure defining a base wall 550, a spaced wall 552, and standoff walls 554. Secondary access openings 556 are formed in the spaced wall 552, while secondary mounting holes 558 are formed in the base wall 550.

Each secondary channel member 530 defines a secondary channel width 570, a secondary channel depth 572, a secondary channel offset distance 574 when secured relative to the diesel housing 22. Further, when secured relative to the diesel housing 22, the secondary channels 530 define a secondary channel spacing distance.
The rail adapter system 522 thus allows the diesel hammer system 20 to be converted into the diesel hammer system 520 as appropriate for use with support members appropriate for the secondary channel spacing distance defined by the secondary channel members 530 simply by forming the bolt assemblies 536 as described above. The rail adapter system 522 allows the diesel hammer system 520 to be converted back into the diesel hammer system 20 appropriate for use with the support members 80 simply by disassembling the bolt assemblies 536 and removing the first and second channel adapter assemblies 524.
