Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of overhead crane current collectors, and in particular relates to a tool for quickly disassembling and assembling overhead crane current collectors. Background Art
[0002] With the improvement of industrial automation, overhead cranes (cranes) play an important role in material handling. As a key component of a crane, the stability of the current collector is directly related to the normal operation of the crane. The structure of the current collector for the overhead crane is provided with a torsion spring, which is used to lift the bracket used to support the current collector upward, thereby ensuring that the contact shoe of the current collector can always maintain contact with the sliding wire, thereby supplying power to the overhead crane. At present, when disassembling and assembling the current collector, it is necessary to separate the contact shoe from the sliding wire first, and due to the effect of the torsion spring, one person needs to hold the bracket to prevent the bracket from rebounding, and then another person disassembles and assembles the current collector. This method is more dangerous, and the slightest negligence will cause the bracket to rebound, which will cause a safety accident. Summary of the invention
[0003] The utility model aims to provide a tool for quickly disassembling and assembling a current collector of a crane, so as to solve the problems existing in the prior art.

[0006] Furthermore, the first clamping plate and the vertical plate are both located on the upper side of the bottom plate and perpendicular to the bottom plate, the cross plate is located at the top end of the vertical plate welded to the bottom plate and perpendicular to the vertical plate, and the second clamping plate is located on the bottom side of the cross plate near one end of the vertical plate and there is a gap between the vertical plate and the vertical plate.
[0007] Furthermore, two clamping rings are welded on the bottom side of one end of the horizontal plate away from the vertical plate.
[0008] Furthermore, the hook is in an arc shape, a sliding rod is welded at one end of the hook, the hook is inserted into two clamping rings through the sliding rod, and a limiting plate is welded after the sliding rod passes through the two clamping rings.

[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0022] As Figures 1-3 shown, a quick disassembly and assembly tool for a crane current collector includes a bottom plate 1, a first clamping plate 2 is provided at one end of the bottom plate 1, a vertical plate 3 is welded to the other end of the bottom plate 1, a cross plate 4 is welded to the vertical plate 3, a hook 5 is inserted into the bottom side of the cross plate 4, and a second clamping plate 6 is welded to the bottom side of the cross plate 4.
[0023] The first clamping plate 2 and the vertical plate 3 are both located on the upper side of the bottom plate 1 and perpendicular to the bottom plate 1. The first clamping plate 2 and the vertical plate 3 are used to clamp both sides of the base 11 of the current collector. The cross plate 4 is located at the top end of the side where the vertical plate 3 is welded to the bottom plate 1 and perpendicular to the vertical plate 3. The second clamping plate 6 is located at the bottom side of the cross plate 4 near one end of the vertical plate 3 and there is a gap between the second clamping plate 6 and the vertical plate 3. The second clamping plate 6 is used to clamp the bracket 13 of the current collector.
[0024] Two clamping rings 7 are welded to the bottom side of the end of the horizontal plate 4 away from the vertical plate 3. The clamping rings 7 are used for inserting the hanging hook 5.
[0025] The hanging hook 5 is arc-shaped. A sliding rod 8 is welded to one end of the hanging hook 5. The hanging hook 5 is inserted into the two clamping rings 7 through the sliding rod 8. A limiting plate 10 is welded after the sliding rod 8 passes through the two clamping rings 7. The sliding rod 8 is used for being inserted into the clamping ring 7 and can rotate and slide within the clamping ring 7. The limiting plate 10 is used to prevent the sliding rod 8 from slipping out of the clamping ring 7.
[0026] A handle 9 is welded to the side of the vertical plate 3 opposite to the bottom plate 1.
[0027] Insulating layers are sprayed on the bottom plate 1, the first clamping plate 2, the vertical plate 3, the horizontal plate 4, the hanging hook 5, the second clamping plate 6, the clamping ring 7, the sliding rod 8, the handle 9, and the limiting plate 10. An insulating sleeve is wrapped around the handle 9.
[0028] The working principle of the present utility model is as follows:
[0029] During use, first bend the bracket 13 of the current collector downward. Hold the handle 9 and push forward to clamp the base 11 and the bracket 13 of the current collector between the bottom plate 1 and the horizontal plate 4 of the present utility model, and make the first clamping plate 2 clamp the base 11. The bracket 13 is stuck in the gap between the second clamping plate 6 and the vertical plate 3. Rotate the hanging hook 5 so that the hanging hook 5 hangs downward on the cross brace 12 of the bracket 13. At this time, release the bracket 13 of the current collector. The bracket 13 is lifted upward under the action of the torsion spring and is then limited between the bottom plate 1 and the horizontal plate 4 by the present utility model. The connection structure between the bracket 13 and the base 11 is similar to the structure of a clip. Due to the action of the torsion spring, the present utility model will also move horizontally due to the tension. At this time, the hanging hook 5 is tightly stuck on the cross brace 12 to prevent further horizontal movement and slipping.
[0030] After the current collector is disassembled and assembled, bend the bracket 13 again to make the base 11 higher than the first clamping plate 2, so that the bracket 13 is disengaged from the limit of the second clamping plate 6, and slightly translate the present utility model to make the hanging hook 5 disengage from the cross brace 4. Hold the handle 9 and take out the present utility model, and then release the bracket 13.
[0031] The above-described embodiments are only used to describe the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solution of the present utility model should all fall within the protection scope of the present utility model.
[0032] The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
