Description

Technical Field

[0001] This utility model relates to the field of intelligent logistics and automated warehouse technology, specifically to a combined maintenance device suitable for elevators. Background Technology

[0002] With the continuous growth in automation demands across various industries, elevators are increasingly being used in smart logistics, automated warehouses, and other scenarios, and their operating conditions are becoming more diversified. Currently, the overall height, stroke, and load of elevators are constantly increasing, and the weight of the drive motor is also significantly increasing, posing serious challenges to the handling, turnover, and maintenance of the motor.

[0003] In existing technologies, the maintenance and hoisting of hoist drive motors typically employs a method of prefabricating H-beams on the building roof: H-beams are pre-installed on the building roof, and hand-operated hoists are suspended from the beams, allowing the motor to be manually hoisted to the designated maintenance location. However, this method has the following significant drawbacks:

[0004] 1. High operational difficulty: When the horizontal or vertical distance between the H-beam on the top of the building and the hoist motor is far, manual operation of the hand-operated hoist requires overcoming significant spatial obstacles, making the operation cumbersome and inefficient.

[0005] 2. Insufficient flexibility: The prefabricated H-beams are fixed to the building structure and cannot be moved with the adjustment of the hoist's position, resulting in the hoisting device not being able to adapt synchronously when the equipment layout is adjusted;

[0006] 3. High cost: When there are multiple hoists on the project site, each piece of equipment needs to be prefabricated with H-beams independently. The duplication of construction leads to a significant increase in material, installation and maintenance costs.

[0007] To address the aforementioned issues, this application provides a combined maintenance device suitable for hoists. Through lightweight and modular design, it enables the integrated installation and flexible use of the hoisting device and the hoist, effectively solving the technical problems of inconvenient operation, poor mobility, and high cost in the prior art.

[0026] See appendix Figure 1As shown, this application discloses a combined maintenance device for hoists, comprising a support assembly 1, a cantilever assembly 2, and a hoisting assembly 3. The device utilizes a modular, detachable structure to facilitate the hoisting of the drive motor. The support assembly 1 includes a left inclined leg 11, a right inclined leg 12, and a rear support leg 13. The left and right inclined legs 11 and 12 are symmetrically arranged on the hoist body, inclined to provide lateral support. The rear support leg 13 is vertically mounted on the hoist body, providing stable vertical support. The left inclined leg 11 has a first mounting plate 14 and a second mounting plate 15 installed at both ends along its length. The right inclined leg 12 has a third mounting plate 16 and a fourth mounting plate 17 installed at both ends along its length. The first and third mounting plates 14 and 16 are both mounted on the hoist body. The left and right inclined legs 11 and 12 form a lateral triangular support with the hoist body, while the rear support leg 13 provides vertical back support, distributing the lateral and longitudinal loads generated during hoisting and ensuring the structure's resistance to overturning. The left inclined support leg 11, the right inclined support leg 12, and the rear support leg 13 are all made of aluminum alloy or carbon fiber, which reduces weight while ensuring structural strength. Each part weighs less than 20kg, and the operator can easily transfer the parts to the motor that needs to be repaired. Then, the repair device is assembled from bottom to top on the hoist.

[0027] The cantilever assembly 2 includes a left cantilever 21 and a right cantilever 22 symmetrically arranged in the horizontal direction. The left cantilever 21 and the right cantilever 22 are detachably connected by a first bolt 4. The left cantilever 21 is detachably connected to a second mounting plate 15, and the right cantilever 22 is detachably connected to a fourth mounting plate 17. One end of the left cantilever 21 and the right cantilever 22 along their length direction is mounted on the top of the rear support leg 13, and the other end is connected to the hoisting assembly 3, which is connected to the drive motor of the hoist. Preferably, the top of the rear support leg 13 is detachably connected to the left cantilever 21 and the right cantilever by a second bolt 5, and the bottom is detachably connected to the hoist body by a third bolt 6. This configuration can withstand vertical loads and resist the overturning moment of the cantilever due to gravity or hoisting force. Due to the symmetrical design of the left cantilever 21 and the right cantilever 22, they are supported at the middle of their length direction by the left inclined support leg 11 and the right inclined support leg 12, and at the end by the rear support leg 13. The vertical load generated by the motor hoisting is transmitted to the left inclined support leg 11, the right inclined support leg 12 and the rear support leg 13 through the left cantilever 21 and the right cantilever 22, forming a stable support system, thereby preventing the cantilever assembly 2 from tilting forward or backward.

[0028] The hoisting assembly 3 includes a sliding trolley 31, a hand-operated hoist 32, and a lifting strap 33. The sliding trolley 31 has a trolley body with rollers embedded in the inner surface tracks of the left cantilever 21 and right cantilever 22. Through the cooperation of the rollers and the cantilever tracks, the sliding trolley 31 can slide back and forth on the cantilever, covering the drive motor maintenance area. It can be precisely aligned with the motor hoisting point through position adjustment. The hand-operated hoist 32 is suspended from the top hook of the sliding trolley 31, forming a detachable connection. The hand-operated hoist 32 uses a chain drive mechanism to achieve vertical lifting and lowering control of the drive motor. The lifting strap 33 is a ring-shaped lifting strap made of high-strength fiber material, with quick-connect buckles at both ends. One end connects to the hoisting point of the drive motor, and the other end connects to the hook of the hand-operated hoist 32. The lifting strap 33 serves as a flexible connector between the motor and the hand-operated hoist 32, adapting to the hoisting needs of motors of different specifications and supporting length adjustment. This application constructs an efficient and safe motor hoisting system through the flexible movement of the sliding trolley 31, the labor-saving lifting and lowering of the hand-operated hoist 32, and the rapid adaptation of the sling 33. Together with the support assembly 1 and the cantilever assembly 2, it forms a complete modular maintenance device, thus solving the problems of fixed hoisting positions, cumbersome operation, and poor compatibility in existing technologies. Preferably, the overall height of the boom in this application is designed to be 1.5-2.5 meters above the maintenance platform, preferably 2 meters, allowing direct operation of the hand-operated hoist 32 without high-altitude work, avoiding operational obstacles caused by the distance between the building roof and the motor in existing technologies. Preferably, the rollers of the sliding trolley 31 are made of rubber, with noise levels below 60 decibels during movement, and it requires no electricity, meeting the requirements of green maintenance.

[0029] Preferred options are listed in the appendix. Figure 1 As shown, in this embodiment, the first mounting plate 14 and the third mounting plate 16 are both detachably connected to the hoist body via the fourth bolt 7, and the second mounting plate 15 and the fourth mounting plate 17 are both detachably connected to the left cantilever 21 and the right cantilever 22 respectively via the fifth bolt 8. The detachable connection of each mounting plate to the hoist body via bolts facilitates quick assembly and disassembly, meeting the needs of multiple devices sharing the same space.

[0030] Preferably, in this embodiment, the joint between the left cantilever 21 and the right cantilever 22 is provided with positioning pin holes and guide bosses. Simultaneously, the connection between the support assembly 1 and the hoist is provided with a universal interface, which can be adapted to the frame of different hoist models, enhancing the versatility of the device. This application adopts a modular, detachable design, such as quick-release bolts and standardized interfaces, allowing the same device to be quickly disassembled and reassembled among multiple hoists, meeting the needs of dynamic equipment layout adjustment in automated production lines.

[0031] Preferably, the outer surfaces of the left oblique support leg 11, the right oblique support leg 12, and the rear support leg 13 in this embodiment are all provided with anti-slip textures or grip handles, which can be held stably during manual handling and improve the comfort of operation.

[0032] Preferably, the first mounting plate 14, the second mounting plate 15, the third mounting plate 16 and the fourth mounting plate 17 in this embodiment adopt a rectangular plate structure with thickness.

[0033] This application is directly installed on the hoist body, without relying on the building structure, and can move synchronously with the equipment position adjustment, completely solving the defect of the prefabricated H-beams in the prior art that cannot be moved.
