[0035] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0036] Electric hoist is a special lifting equipment, installed on the overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, warehouses, docks and other places. The electric hoist has a compact structure, and the electric hoist with the motor axis perpendicular to the drum axis adopts a worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, difficult processing, etc. The hydraulic system is double-controlled, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. The electrical control department adopts low voltage control to increase the safety of the control system.

[0037] As mentioned in the background technology, electric hoists need to be repaired after long-term use to reduce safety hazards during use. The inventors have found that existing maintenance work is usually carried out on a work platform, but there is a certain height difference between the work platform and the bottom surface, which poses certain safety hazards during the maintenance process. In addition, the activity space on the work platform is relatively limited, and there is also the problem of inconvenient maintenance.

[0038] Please refer to Figure 1 and Figure 2 The electric hoist maintenance system 100 and the electric hoist maintenance method provided in the embodiments of the present invention can solve the above problems, which will be described in detail below.

[0039] The electric hoist maintenance system 100 includes a moving guide rail 110, a working platform 120 and a supporting hook 130;

[0040] Among them, the movable guide rail 110 is used to detachably connect the electric hoist 190, the working platform 120 is arranged at an interval on one side of the movable guide rail 110, and the support hook 130 is arranged on the working platform 120. The working platform 120 is used to carry workers to separate the electric hoist 190 and the movable guide rail 110, and to hang the carrying hook 195 of the electric hoist 190 on the support hook 130, and then move the electric hoist 190 away from the support hook 130 toward a lower place.

[0041] When maintenance work is required, the staff can first hang the load-bearing hook 195 on the support hook 130 on the working platform 120, and then separate the electric hoist 190 and the movable guide rail 110, and control the electric hoist 190 to move toward the ground, so as to facilitate the staff to carry out maintenance work directly on the ground, avoid safety hazards caused by the height difference with the ground, and will not be restricted by the working platform 120 to affect the convenience of maintenance work.

[0042] It is worth noting that when the electric hoist 190 is performing a hoisting operation, the hoist rope will be released, so that the load hook 195 moves toward a lower position under its own weight to perform the hoisting operation. When the load hook 195 is hooked to the support hook 130, the electric hoist 190 is located at the lower side of the load hook 195, and the hoist rope is continuously released, and the electric hoist 190 moves toward a lower position with its own weight, so that it can be conveniently moved to the ground or a position close to the ground for maintenance operations.

[0043] In addition, the working platform 120 is spaced apart from the moving guide rail 110, so that the existence of the working platform 120 can avoid interference with the moving guide rail 110 and the electric hoist 190 sliding along the moving guide rail 110. Before and after the maintenance work, there is no need to make special adjustments to the working platform 120, which helps to improve the maintenance effect and reduce the labor intensity of the workers.

[0044] In this embodiment, the support hook 130 is disposed at the top of the working platform 120. Furthermore, the support hook 130 can be disposed higher than the movable guide rail 110. Of course, in other embodiments of the present invention, the support hook 130 and the movable guide rail 110 can also be disposed flush with each other in the height direction, and the relative position height of the support hook 130 and the movable guide rail 110 is not limited.

[0045] In this embodiment, there are two sets of working platforms 120 and supporting hooks 130, which are respectively arranged at both ends of the moving guide rail 110. When maintenance work is required, the electric hoist 190 can be slid to both ends of the moving guide rail 110, thereby facilitating the operation of the staff.

[0046] Of course, in other embodiments of the present invention, the number of the working platform 120 and the supporting hook 130 can also be set as one group, which can be set on one side of any position in the extension direction of the moving guide rail 110. In addition, when the extension length of the moving guide rail 110 is long enough, the number of the working platform 120 and the supporting hook 130 can also be set as at least three groups, and they can be set at equal intervals along the extension direction of the moving guide rail 110, so as to facilitate the maintenance of the electric hoist 190 at different positions, help improve the efficiency before maintenance, and avoid the electric hoist 190 from sliding too long on the moving guide rail 110 before maintenance.

[0047] refer to Figure 1 In order to further improve the hanging flexibility of the load-bearing hook 195 , the electric hoist maintenance system 100 may further include a telescopic mechanism 140 , which is connected between the support hook 130 and the working platform 120 .

[0048] In the working state, the telescopic mechanism 140 can drive the support hook 130 to adjust its height by itself. Specifically, the telescopic extension direction of the telescopic mechanism 140 can be perpendicular to the extension direction of the moving guide rail 110.

[0049] refer to Figure 1 In order to improve the structural stability of the working platform 120, the working platform 120 may be in a trapezoidal structure with a small top and a large bottom.

[0050] Of course, in other embodiments of the present invention, the working platform 120 may also be a rectangular parallelepiped, cylindrical or other structure, and the specific structural shape of the working platform 120 is not limited.

[0051] refer to Figure 2 The embodiment of the present invention further provides an electric hoist maintenance method, which is implemented by the electric hoist maintenance system 100. The electric hoist maintenance method includes:

[0052] S100 : Control the electric hoist 190 to move along the moving guide rail 110 to approach the working platform 120 , so that the staff can stand on the working platform 120 to operate the electric hoist 190 .

[0053] S200: Control the load hook 195 to be hooked on the support hook 130 ; specifically, the worker lifts the load hook 195 located at the lower side of the electric hoist 190 and hooks it on the support hook 130 , so that the lifting rope connected to the load hook 195 is located at the lower side of the load hook 195 .

[0054] Furthermore, during this process, the telescopic height of the telescopic mechanism 140 can be adjusted to drive the support hook 130 to move to a suitable height, thereby facilitating the hanging of the load-bearing hook 195 .

[0055] S300: Control the electric hoist 190 to separate from the movable guide rail 110; specifically, by dismantling the fasteners on the electric hoist 190, the electric hoist 190 is removed from the movable guide rail 110, and the electric hoist 190 is located at the lower side of the load-bearing hook 195 under the action of its own gravity.

[0056] S400: Control the electric hoist 190 to move toward a lower place for maintenance work; specifically, the staff controls the electric hoist 190 to release the lifting rope through the remote control, because the load-bearing hook 195 at the other end of the lifting rope is hung on the support hook 130, and its position is relatively fixed, and the electric hoist 190 will descend in accordance with its own gravity during the process of releasing the lifting rope, and descend to a suitable height, so that the staff can directly perform maintenance work on the electric hoist 190 on the ground.

[0057] Compared with the prior art, in this electric hoist maintenance method, the staff can perform maintenance work directly on the ground. Compared with performing maintenance work at a high place, there will be no safety hazard due to the height difference with the ground. It is also convenient to transfer the maintenance work, and the maintenance space is larger, which is convenient for maintenance personnel to move flexibly so as to perform maintenance on different sides of the electric hoist 190. At the same time, the setting of the working platform 120 will not interfere with the moving guide rail 110 and the electric hoist 190. There is no need to temporarily build it before maintenance, and there is no need to dismantle it in time after maintenance, thereby improving the work efficiency before and after maintenance, and facilitating the timely resumption of hoisting operations after maintenance.

[0058] In summary, the electric hoist maintenance system 100 and the electric hoist maintenance method provided by the embodiments of the present invention have at least the following advantages:

[0059] (1) It allows the worker to first hook the load-bearing hook 195 to the support hook 130 on the working platform 120, and then separate the electric hoist 190 and the movable guide rail 110, and control the electric hoist 190 to move toward the ground, thereby facilitating the worker to perform maintenance work directly on the ground, avoiding safety hazards caused by the height difference with the ground, and not affecting the convenience of maintenance work due to the limitation of the working platform 120.

[0060] (2) By setting a telescopic mechanism 140 between the support hook 130 and the working platform 120, the telescopic mechanism 140 can drive the support hook 130 to adjust its height by its own telescopic movement, so as to facilitate driving the support hook 130 to a suitable height, thereby improving the hanging flexibility of the load-bearing hook 195.

[0061] (3) By spacing the working platform 120 from the moving guide rail 110, it is possible to avoid interference of the working platform 120 with the moving guide rail 110 and the electric hoist 190 sliding along the moving guide rail 110. Before and after the maintenance work, there is no need to make special adjustments to the working platform 120, which helps to improve the maintenance effect and reduce the labor intensity of the workers.

[0062] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
