This invention relates generally to vehicles and, more particularly, to a vehicle having a horizontally rotatable multi-knuckle boom.
Vehicles having spray booms for spraying liquids during mining have typically included booms that can fold, extend and rotate about a horizontal axis perpendicular to a direction of motion of the vehicle. A vehicle having a boom with greater degrees of movement and easier methods of rotation is desired.
A first aspect of the present invention is to provide a mining vehicle for spraying a fluid. The mining vehicle includes a vehicle portion having a propulsion system for propelling the mining vehicle, a boom connected to the vehicle portion, and a hydraulically driven pivot assembly connecting the boom to the vehicle portion. The pivot assembly includes a horizontal axis pivot member to allow the boom to pivot about the vehicle portion about a first horizontal axis. The boom comprises at least three boom arms and a nozzle on an end thereof, with each of the boom arms being pivotable about an adjacent one of the boom arms about a second axis. The second axis is substantially perpendicular to the first horizontal axis.
Another aspect of the present invention is to provide a mining assembly for spraying a fluid comprising a base, a boom connected to the base, and a hydraulically driven pivot assembly connecting the boom to the base. The pivot assembly includes a horizontal axis pivot member to allow the boom to pivot about the base about a first horizontal axis. The boom comprises at least three boom arms and a nozzle on an end thereof, with each of the boom arms being pivotable about an adjacent one of the boom arms about a second axis. The second axis is substantially perpendicular to the first horizontal axis. The mining assembly also includes a tube system extending between the base and the nozzle, with the tube system being configured to supply the fluid from the base to the nozzle for spraying the fluid out of the nozzle.
Yet another aspect of the present invention is to provide a mining vehicle for spraying a fluid comprising a vehicle portion having a propulsion system comprising wheel for propelling the mining vehicle, a boom connected to the vehicle portion, and a hydraulically driven pivot assembly connecting the boom to the vehicle portion. The pivot assembly includes a horizontal axis pivot member to allow the boom to pivot about the vehicle portion about a first horizontal axis. The boom comprises at least three boom arms and a nozzle on an end thereof, with each of the boom arms being pivotable about an adjacent one of the boom arms about a second axis. The second axis is substantially perpendicular to the first horizontal axis. The mining vehicle also includes a tube system extending between the vehicle portion and the nozzle, with the tube system being configured to supply the fluid from the vehicle portion to the nozzle for spraying the fluid out of the nozzle. At least one of the boom arms is a telescoping arm having the nozzle on a distal end thereof. Each adjacent pair of the boom arms have an actuator pivotally connected thereto for rotating the boom arms relative to each other about the second axis.
For purposes of description herein, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined herein. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless expressly stated otherwise.
The reference number 10 (
The illustrated front vehicle portion 12 propels the vehicle 10. The front vehicle portion 12 includes an engine for driving the vehicle 10 and at least one pair of driven wheels 17 for propelling the vehicle 10 (e.g., four wheel drive with two pairs of driven wheels 17). The pair of driven wheels 17 can be connected by a solid axle or cradle axle. Cradle axles are well known to those skilled in the art and any cradle axle can be used. For example, the front vehicle portion 12 can have the cradle axle discussed in U.S. Pat. No. 4,082,377 entitled AXLE CRADLE MOUNTING HAVING ELASTOMERIC SPHERICAL BUSHINGS, the entire contents of which are hereby incorporated herein by reference. The rear vehicle portion 14 can comprise a trailer or any other structure and can include at least one axle (solid or cradle) having a pair of wheels 19 connected to ends thereof.
In the illustrated example, the front vehicle portion 12 includes a boom 20 that can rotate about a horizontal axis 25 relative to the front vehicle portion 12 by a horizontal axis pivot assembly 30 having a pivot actuator 26. The boom 20 can be used for carrying anything on an end thereof. In the illustrated example, the boom 20 includes an articulating nozzle 22 on an end thereof. The articulating nozzle 22 can be used in any application including for spraying a fluid therethrough for use in mining as is well known to those skilled in the art. The fluid is supplied to the nozzle 22 from the vehicle through tubing 36 connected to the boom 20.
The illustrated boom 20 includes a first arm 24 connected to the horizontal axis pivot assembly 30, a second arm 28, a third arm 32 and a fourth telescoping arm 34 having the articulating nozzle 22 on a distal end thereof. The first arm 24, the second arm 28, the third arm 32 and the fourth telescoping arm 34 are pivotable relative to each other to allow the boom 20 to move from a folded position as illustrated in
In the illustrated example, the horizontal axis pivot assembly 30 (
The illustrated external cylinder 38 of the pivot actuator 26 of the horizontal axis pivot assembly 30 is fixedly connected to the vehicle 10 to allow the internal cylinder 40 to rotate about the horizontal axis 25. The front vehicle portion 12 of the vehicle 10 includes a proximal connection collar 48 and a distal connection collar 50. The proximal connection collar 48 includes a substantially block-shaped base plate 52 and a ring collar portion 54 extending from the base plate 52. The base plate 52 of the proximal connection collar 48 is fixed to the front vehicle portion 12 and the ring collar portion 54 surrounds an exterior periphery of a proximal side circumferential surface of the external cylinder 38 of the pivot actuator 26. The ring collar portion 54 of the proximal connection collar 48 is fixed to the external cylinder 38 of the pivot actuator 26 by any means (e.g., fasteners). Similarly, the distal connection collar 50 includes a substantially block-shaped base plate 56 and a ring collar portion 58 extending from the base plate 56. The base plate 56 of the distal connection collar 50 is fixed to the front vehicle portion 12 (by, e.g., fasteners) and the ring collar portion 58 surrounds an exterior periphery of a distal side circumferential surface of the external cylinder 38 of the pivot actuator 26. The ring collar portion 58 of the distal side connection collar 50 is fixed to the external cylinder 38 of the pivot actuator 26 by any means (e.g., fasteners). It is contemplated that the proximal connection collar 48 and the distal connection collar 50 could be fixed to a plate or similar structure rotatably connected to the vehicle 10 to allow the boom 20 to be rotatable about a vertical axis to provide even greater range of motion for the boom 20.
In the illustrated example, the horizontal axis pivot assembly 30 further includes a pivot connection 60 fixed to the proximal cap 42 and the distal cap 44 and connected to the first arm 24 of the boom 20 for transferring rotary motion of the pivot actuator 26 to the first arm 24 of the boom 20. The pivot connection 60 includes a top plate 62 fixed to top edges of the proximal cap 42 and the distal cap 44. The top plate 62 is substantially I-shaped when viewed from above and includes a proximal side end 64, a distal side end 66 and a thin extension 68 extending between the proximal side end 64 and the distal side end 66. A top of the proximal cap 42 is fixed to the proximal side end 64 (by, e.g., fasteners) and a top of the distal cap 44 is fixed to the distal side end 66 (by, e.g., fasteners). A plurality of angled struts 67 can extend between the proximal surface of the proximal cap 42 and a bottom surface of the proximal side end 64 of the top plate 62 to reinforce the connection between the proximal cap 42 and the top plate 62. The top plate 62 rotates with the internal cylinder 40 of the pivot actuator 26, the distal cap 44 and the proximal cap 42. The distal cap 44 and the distal side end 66 of the top plate 62 are fixed to the first arm 24.
The illustrated first arm 24 of the boom 20 is fixed to the horizontal axis pivot assembly 30 to allow the horizontal axis pivot assembly 30 to rotate the first arm 24 and the boom 20 about the horizontal axis 25. The first arm 24 includes a pair of parallel planar side walls 70, an angled middle wall 72 and an end wall 74. The pair of parallel planar side walls 70 have a proximal side edge connected to the distal cap 44 of the horizontal axis pivot assembly 30. A pair of co-planar tabs 76 extend from a distal edge of the top plate 62 of the horizontal axis pivot assembly 30 and are connected to proximal side top edges of the pair of parallel planar side walls 70 of the first arm 24. The angled middle wall 72 of the first arm 24 extends between the pair of parallel planar side walls 70 and is connected thereto. The angled middle wall 72 has a higher proximal side connected to a bottom of the distal side end 66 of the top plate 62 of the horizontal axis pivot assembly 30. A lower distal side of the angled middle wall 72 terminates at a bottom distal side of the first arm 24. The end wall 74 extends between the pair of parallel planar side walls 70 in a substantially vertical orientation. A lower edge of the end wall 74 is spaced from the lower distal side of the angled middle wall 72 to create a second arm receiving space 78 therebetween. The second arm 28 is pivotally connected to the first arm 24.
In the illustrated example, the second arm 28 (

In the illustrated example, the first articulating assembly 102 includes a first expandable cylinder 104 having a proximal end pivotally connected to the first arm 24 by a first pin 106 and a distal end pivotally connected to the second arm 28. The distal end of the first expandable cylinder 104 is connected to the second arm 28 at a location adjacent a center area of the second arm 28, but closer to the third arm 32 than the first arm 24 (at a location adjacent an end of the bottom step 91 of the angled stepped plate 84). The first pin 106 extends between the pair of parallel planar side walls 70 above the end wall 74 of the first arm 24. The first expandable cylinder 104 includes a ring surrounding the first pin 106 in a center area 107 thereof. A pair of sleeves 108 surround the center area 107 of the first pin 106 to maintain a position of the first expandable cylinder 104 on the first arm 24. The first expandable cylinder 104 can comprise a pair of telescoping tubes, with the interior tube being driven hydraulically or pneumatically into and out of the exterior tube. When the first expandable cylinder 104 is in a contracted position, the distal end of the second arm 28 connected to the third arm 32 rotates away from the first arm 24 as illustrated in
