Description

Technical Field

[0001] The utility model relates to the technical field of maintenance equipment for cranes, and particularly to a dismounting and mounting tool for a traveling wheel. Background Art

[0002] Lifting equipment is an important equipment in all walks of life. During its use, failures will inevitably occur. Especially when its traveling wheels fail and need to be replaced and repaired. Generally, there are two traveling wheels in a crane. One is the large vehicle wheel that drives the crane and the goods to run together, and the other is the small vehicle wheel at the top of the crane. For the replacement of the large vehicle wheel, it is necessary to use a large-tonnage lifting equipment or a large jack to lift the whole crane, and then use other tools (such as a chain block, etc.) to disassemble and replace the wheel. For the replacement of the small vehicle wheel, a lot of manpower and material resources are also required. At the same time, in other large equipment with a traveling wheel structure similar to that of a crane, the dismounting and mounting of its traveling wheels also consume a large amount of manpower and material resources, such as the trolley wheels in a maglev turnout.

[0003] The existing wheel dismounting process of lifting equipment is as follows: Transport the new wheel to the area where the wheel needs to be replaced, then use tools such as a jack to lift the crane girder to a certain height to separate the wheel from the track, and then use tools such as a chain block to wrap and pull out the old wheel, and then pull up the new wheel. The jack is depressurized, and the girder falls again to press the new wheel on the track, and the overall efficiency is low. And due to the limited space at the installation position of some equipment, the space is limited when using tools such as a chain block to remove and install the wheel, which is not convenient for operation.

[0031] The following will elaborate on the embodiments of the utility model in detail with reference to the drawings. However, the utility model can be implemented in various different ways defined and covered by the following.

[0032] As Figures 1 - 5 shown, a disassembly and assembly tool for a walking wheel according to this embodiment includes a vehicle frame 10 and a support assembly 20, and the support assembly 20 is hinged to the vehicle frame 10. The vehicle frame 10 can move along the track. The support assembly 20 can move along with the vehicle frame 10.

[0033] The support assembly 20 can swing to a first state, in which the support assembly 20 supports on the walking wheel; the support assembly 20 can swing to a second state, and the height of the support assembly 20 in the second state is lower than the height of the support assembly 20 in the first state.

[0034] It should be noted that when using a lifting tool such as a jack to move the entire walking wheel frame upward (perpendicular to the track direction) to separate the walking wheel from the track, a narrow space is formed between the walking wheel and the track. By enabling the support assembly 20 to swing to the second state with a relatively low height, it can pass through the narrow space between the walking wheel and the track.

[0035] By making the support assembly 20 in the second state, it is convenient to move it to the lower part of the walking wheel. Then swing the support assembly 20 to the first state so that the support assembly 20 can support on the walking wheel. After the walking wheel is disassembled, the vehicle frame 10 can be moved together with the walking wheel by moving the vehicle frame 10. During installation, the walking wheel can also be supported on the support assembly 20 in the first state, so as to be conveniently moved to the installation position, and then swing the support assembly 20 to the second state to facilitate moving out from under the walking wheel.

[0036] In some embodiments, the support assembly 20 includes two first support members 21, and the two first support members 21 are arranged in sequence along the moving direction of the vehicle frame 10, and the two first support members 21 are hinged to the vehicle frame 10. In this way, the two first support members 21 can swing relative to the vehicle frame 10, and the swing axis is the hinge axis.

[0037] The two first support members 21 can swing relative to each other to a first state, in which the two first support members 21 support the walking wheel between them at a preset angle. The two first support members 21 can swing away from each other to a second state, and the height of the two first support members 21 in the first state is higher than the height of at least one of the first support members 21 in the second state.

[0038] It can be understood that the two first support members 21 are arranged in sequence along the moving direction of the vehicle frame 10. When they swing relative to each other, the ends away from the hinge of the two first support members 21 approach each other in the moving direction of the vehicle frame 10.

[0039] In the first state, the two first support members 21 support the running wheel between them at a preset angle. It can be understood that the preset angle is not limited, and when the diameter or height of the running wheel changes, the preset angle changes adaptively.

[0040] It can be understood that when the running wheel is supported between the two first support members 21 , the running wheel is limited by the two first support members 21 .

[0041] The two second support members 22 are arranged in one-to-one correspondence with the first support members 21 , that is, one second support member 22 is arranged corresponding to each first support member 21 .

[0042] The second support member 22 can be supported on a side of any first support member 21 away from another first support member 21, so that the first support member 21 is maintained in the first state. Figure 1 In the embodiment, one second support member 22 can be supported on the left side of the left first support member 21, and another second support member 22 can be supported on the right side of the right first support member 21. In this way, the angle between the two first support members 21 is kept fixed, thereby providing support for the travel wheels.

[0043] It can be understood that by making the two first support members 21 swing relative to each other to the first state, the two first support members 21 are at a preset angle to contact the running wheel, and then the second support member 22 supports the side of the first support member 21 away from the running wheel, so that the angle between the two first support members 21 remains fixed, thereby providing continuous limitation and support for the running wheel. After the running wheel is disassembled, it can be connected to the running wheel by the moving frame 10 and moved together. During installation, it is also possible to support the running wheel on the two first support members 21, so as to facilitate moving to the installation position. The above operation process is simple and convenient, and since there is no need to use tools such as hand winches to remove and install the running wheels, the space is relatively unlimited and the scope of application is wide.

[0044] In some embodiments, the two first support members 21 can swing away from each other to the second state. It is understandable that when the two support members 21 swing away from each other, the ends of the two support members 21 away from the hinge move away from each other in the moving direction of the vehicle frame 10 .

[0045] The heights of the two first support members 21 in the first state are higher than the height of at least one first support member 21 in the second state.

[0046] It can be understood that, since the height of the at least one first support member 21 in the second state is relatively low, it can pass through a space with a lower height.

[0047] In some embodiments, the height of the two first support members 21 in the first state is higher than the height of the two first support members 21 in the second state.

[0048] In some embodiments, the second support member 22 is hinged to the vehicle frame 10. The second support member 22 is located on a side of any one of the first support members 21 away from the other first support member 21. In this way, the second support member 22 can swing around the hinged end. When it is necessary to support the first support member 21, it is only necessary to swing the second support member 22 until it supports on the side of the first support member 21 away from the other first support member 21, and the operation is relatively simple and convenient.

[0049] In order to improve the stability of the support of the second support member 22, in some embodiments, the back surface of the first support member 21 has a plurality of card slots distributed along its own length direction, and the second support member 22 can be supported in any one of the card slots for limiting. Thereby, it is avoided that the second support member 22 slides on the surface of the first support member 21 under the action of gravity.

[0050] It can be understood that the shape of the first support member 21 is not limited. In some embodiments, the first support member 21 includes a first support portion 211 and first folded edge portions 212 bent downward from both sides in the width direction of the first support portion 211. Among them, the first folded edge portions 212 located on both sides in the width direction of the first support portion 211 can improve the strength of the first support member 21 in the length direction of itself, so as to adapt to large-weight traveling wheels.

[0051] It can be understood that, in order to reduce the overall size in the second state, in some embodiments, in the second state, one end of the first support member 21 away from the hinged position supports on the vehicle frame 10, and a cavity is defined by the vehicle frame 10, the first support portion 211 and the first folded edge portion 212, and part or all of the length direction of the second support member 22 can be received in the cavity. In this way, in the second state, the overall size of the first support member 21 and the second support member 22 is smaller.

[0052] It can be understood that the shape of the second support member 22 is not limited. In some embodiments, the second support member 22 includes a second support portion 221 and second folded edge portions 222 bent downward from both sides in the width direction of the second support portion 221. Among them, the second folded edge portions 222 located on both sides in the width direction of the second support portion 221 can improve the strength of the second support member 22 in the length direction of itself, so as to adapt to large-weight traveling wheels.

[0053] In order to protect the running wheel from being scratched, in some embodiments, a flexible supporting layer is provided on the surface of the first supporting member 21 supporting the running wheel. It is understandable that the flexible supporting layer can protect the running wheel from being scratched by deforming itself, and at the same time, the deformation increases the contact area between the flexible supporting layer and the running wheel, thereby increasing the friction between the flexible supporting layer and the running wheel and preventing the running wheel from moving.

[0054] The flexible supporting layer may be made of rubber.

[0055] It is understandable that the frame 10 includes wheels 50 and a frame body, and the wheels 50 can be rotatably arranged on the frame body through an axle. The wheels 50 are used to reduce resistance during movement.

[0056] It is understandable that there are many types of installation structures for the running wheels. Figure 5 In the installation structure shown, after the running wheel is disassembled, the running wheel frame needs to be raised or the height of the disassembled running wheel needs to be lowered so that the running wheel can be moved out of the running wheel frame.

[0057] In some embodiments, the frame 10 includes a frame body, wheels 50 and a first lifting assembly, wherein the first lifting assembly is disposed between the frame body and the wheels 50 to adjust the height of the frame body relative to the wheels 50 to facilitate moving the walking wheels out of the walking wheel frame.

[0058] In some embodiments, the walking wheel disassembly and assembly tool further includes a second lifting assembly, and the second lifting assembly is used to lift the walking wheel frame. It is understandable that when using the walking wheel disassembly and assembly tool to assist in the replacement of the walking wheel, it is necessary to first separate the walking wheel from the track. The above separation action can be achieved by an externally purchased jack or other equipment, or it can be achieved by the second lifting assembly of the walking wheel disassembly and assembly tool.

[0059] Please refer to Figure 5In some embodiments, the disassembly and assembly process of the traveling wheel is as follows: move the dismantling tool in the second state to the vicinity of the traveling wheel to be dismantled; use a lifting tool such as a jack to move the traveling wheel frame as a whole upward (perpendicular to the track direction) to disengage the traveling wheel from the track, and at the same time move the dismantling tool to the bottom of the traveling wheel to be dismantled, rotate the first support member 21 to the first state, at which time the first support member 21 contacts the circumferential side wall of the traveling wheel, and rotate the second support member 22 to a position that supports the first support member 21 to fix the traveling wheel. Remove the constraint of the traveling wheel and move the dismantling tool together with the traveling wheel in the opposite direction. Move the traveling wheel to other areas for maintenance work, and the relative position between the traveling wheel and the dismantling tool can be marked before maintenance. Then place the new running wheel or the running wheel after repair on the dismantling tooling, and adjust and place the running wheel according to the marks made in the early stage, which can save the time for subsequent installation and positioning of the running wheel. Push the dismantling tooling under the running wheel frame, fix the various constraints of the running wheel, rotate the first support member 21 and the second support member 22 on the dismantling tooling in opposite directions, and then restore the lifting tool under the running wheel frame to its original position to ensure that the running wheel falls on the track. At this point, the replacement of the running wheel is completed.

[0060] Please refer to Figures 1 - 4 In some embodiments, the support assembly 20 is arranged in two groups in parallel and at intervals to better match the walking wheels.

[0061] In some embodiments, the vehicle frame 10 includes two main beams 11 arranged in parallel and spaced apart, and a cross beam 12 connecting the two main beams 11, and each group of the support components 20 is correspondingly arranged on one of the main beams 11. Each main beam 11 supports each group of the support components 20, and the support reliability is good.

[0062] In some embodiments, the interval between the two main beams 11 is adjustable to accommodate different traveling wheels.

[0063] It is understood that the adjustable structure between the two main beams 11 is not limited. In some embodiments, the cross beam 12 forms a strip hole 12a extending along the width direction of the frame 10. The frame 10 also includes a fastener 30, which passes through the strip hole 12a and is fastened to the main beam 11. When the fastener 30 is released, the main beam 11 can be moved along the extension direction of the strip hole 12a, thereby achieving the adjustment of the interval between the two main beams 11.

[0064] In some embodiments, the frame 10 further includes a handrail 40 , which is disposed at one end of the moving direction of the frame 10 . The operator moves the frame 10 through the handrail 40 .

[0065] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
