The present invention relates to the field of a device for mounting and dismounting a part, and more particularly to a flange cover mounting and dismounting device.
Currently, for most large scale equipment, especially large scale cooling equipment, the process of mounting and dismounting a flange cover is rather complicated. Generally, the position and weight of the flange cover in such equipment decide that the flange cover cannot be mounted and dismounted manually. Instead, it shall be mounted and dismounted by using a tool such as a hanging pillar. Unfortunately, some fragile parts may be disposed surrounding the flange cover, or the flange cover may be interfered with some other parts. Thus, during the overall process of hanging, mounting, and dismounting, it shall pay a special attention to a running route of the hanging pillar. For example, in some large scale horizontal-type coolers, when a flange cover is mounted and dismounted, a conventional vertical-lifting hanging pillar is used to lift the flange cover upwards, it may crash some other parts, and result in damages of the parts, which may even cause security accidents, if serious. In contrast, if a conventional horizontal-rotating hanging pillar is used to lift the flange cover, on one hand, it is difficult to figure out an exact fixing position, and on the other hand, it needs to be adjusted in many factors such as height, length, and so on, to cater to coolers with different sizes, which is extremely complicated and not convenient for operation.
An object of the present invention is to provide a flange cover mounting and dismounting device, which can be easily mounted and widely applied.
According to an aspect of the present invention, the present invention provides a flange cover mounting and dismounting device, which comprises: a base part, comprising a fastener element with a fastener hole array, and being fastened to a flange cover mounting surface by the fastener hole array; and a jib arm assembly, being pivotally connected to the fastener element.
Optionally, the base part further comprises: an adjusting element, connected with the fastener element, and used for clamping the flange cover mounting surface from edges of the flange cover mounting surface.
Optionally, the adjusting element comprises a fixing mechanism and a clamping mechanism that can move relative to each other. The fixing mechanism is connected with the fastener element; and the clamping mechanism clamps the flange cover mounting surface from edges of the flange cover mounting surface.
Optionally, the fixing mechanism is an L-shaped bracket. One side of the L-shaped bracket is connected with the fastener element, and the other side of the L-shaped bracket is disposed with a sliding chute extending along a length direction thereof. The clamping mechanism moves relative to the fixing mechanism along the sliding chute.
Optionally, the fastener element comprises: a first mounting plate with the fastener hole array; an upper plate and a lower plate, respectively extending from two ends of the first mounting plate and bending towards the same side; and a sleeve, disposed between the upper plate and the lower plate.
Optionally, a side wall on a lower part of the sleeve is disposed with an oil hole for a lubricating oil to pass through.
Optionally, the jib arm assembly comprises: a support pillar, a swing arm, and a lifting lever. The support pillar is pivotally connected to the fastener element. The swing arm is connected to the support pillar, and is pivotally rotated about the support pillar. The lifting lever moves along a length direction of the swing arm, and is connected to a flange cover to be mounted and dismounted.
Optionally, the jib arm assembly further comprises a cover plate disposed with a first limiting mechanism, the cover plate is placed surrounding the support pillar, and fixed on the fastener element. The swing arm is disposed with a second limiting mechanism matching with the first limiting mechanism.
Optionally, the flange cover mounting and dismounting device is used for mounting and/or dismounting a flange cover matching with a device to be mounted and dismounted.
According to another aspect of the present invention, the present invention further provides a cooling device, which comprises a flange cover and a flange cover mounting surface. A fastener hole array is disposed on the flange cover mounting surface. The fastener hole array on the flange cover mounting surface is matched with the fastener hole array on the flange cover mounting and dismounting device as mentioned above.
Optionally, the fastener hole array on the flange cover mounting surface is three holes in a staggered arrangement.
The flange cover mounting and dismounting device according to the present invention can be fixed to the flange cover mounting surface having a corresponding fastener hole array by means of a fastener hole array, which is convenient for mounting and dismounting a flange cover. In addition, under most circumstances, the fastener hole array on the flange cover mounting surface is intrinsically owned by the devices, which originally can be applied to connect modules of each device or used for other applications. Therefore, the flange cover mounting and dismounting device provided in the present invention not only has a mounting and dismounting function, but also has advantages such as being easily mounted, being widely applied, and so on.
The adjusting element 120 comprises a fixing mechanism 121 and a clamping mechanism 122. The fixing mechanism 121 is an L-shaped bracket having a first edge 121a and a second edge 121b. The first edge 121a is disposed with a bolt hole, and is fixed on the fastener element 110 by using a bolt. Optionally, the first edge 121a is fixed on the upper plate 112, and does not shield the first opening 114a of the sleeve 114. The second edge 121b is placed in parallel with the first mounting plate 111, and is disposed with a sliding chute 121c thereon. The clamping mechanism 122 comprises a first clamping element 122a and a second clamping element 122b. The first clamping element 122a is also an L-shaped element, and is disposed with a bolt hole on one edge thereof, and this edge is disposed in parallel with the second edge 121b of the fixing mechanism 121, whereas the other edge thereof is perpendicular to the second edge 121b of the fixing mechanism 121, and is further disposed with a groove for the second edge 121b of the fixing mechanism 121 to move up and down. The second clamping element 122b is similarly disposed with a bolt hole. A first fastening bolt 122c can sequentially pass through the second clamping element 122b, the sliding chute 121c on the second edge 121b of the fixing mechanism 121, and the first clamping element 122a, and fasten them together. Before the fastening operation, the first clamping element 122a and the second clamping element 122b can be moved up and down with respect to the second edge 121b of the fixing mechanism 121, thereby catering to flange cover mounting surfaces with different sizes.
In the base part 110, the fastener element 110 is used to be fixed to a mounting surface of a flange cover to be mounted and dismounted by the fastener hole array 111a. The adjusting element 120 is used to clamp the flange cover mounting surface to further enhance the fastening effects. Meanwhile, the adjusting element 120 can be adjusted up and down and front and back respectively, to cater to flange cover mounting surfaces with different sizes and different thicknesses. In this way, the mounting and dismounting device of the present invention can be more widely applied. Thus, it does not need to design different mounting and dismounting devices for equipment with different sizes and different models respectively, thereby greatly reducing the cost.
Optionally, in order to maintain the jib arm assembly 200 within a certain pivotally rotating angle, to avoid crashing between parts, a limiting mechanism may be further disposed to meet the above requirements. For example, a limiting bump 210c is disposed on the cover plate 210b, and a limiting board 210a is disposed on the support pillar 210. By means of the matching effects between the limiting bump 210c and the limiting board 210a, the pivotally rotating motion of the jib arm assembly 200 is restricted.
It shall be noted that, many mature jib arm assemblies are provided in the prior art, and as long as the jib arm assembly can be matched with the base part 100 of the present invention, it can similarly constitute the flange cover mounting and dismounting device of the present invention.
After the device for dismounting the flange cover is assembled and fixed, the flange cover in the cooling device is connected to the hanging ring 230a of the lifting lever 230 by means of a cable, and the lifting lever 230 is moved along a length direction of the swing arm 220, so as to be adjusted to a most proper lifting position. Then, the fastening bolts at the edges of the flange cover are all dismounted, and then, the swing arm 220 is rotated to open and lift the flange cover, thereby dismounting the flange cover. Considering the mounting process of the flange cover, similar steps can be used. Such mounting and dismounting operations can effectively avoid the problem that several parts may be crashed with the flange cover when the flange cover is lifted vertically.
In addition, the flange cover mounting and dismounting device of the present invention can also be applied to mount and/or dismount the flange cover of other devices to be mounted and/or dismounted. When such device is laid down horizontally, or when the flange cover of such device to be mounted and dismounted needs to be mounted or dismounted with respect to the device to be mounted and dismounted along a horizontal direction, the flange cover mounting and dismounting device of the present invention has greater advantages. For example, the flange cover mounting and dismounting device has a more proper fixing surface; and drives the jib arm assembly to pivotally rotate along a horizontal direction, thereby avoiding crashing various other parts and elements distributed in the perpendicular direction, and enhancing the security level.
