[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figures 1 to 4 The elevator maintenance parts classification device shown includes:

[0027] Main structure;

[0028] The main structure includes a bottom layer accessory storage box 1, a multi-layer middle layer accessory storage box 2 and a top layer tool storage box 3;

[0029] Four sets of limit rods 4 are rotatably connected to the top of the top tool storage box 3 through bearings. The bottom ends of the limit rods 4 pass through the middle accessory storage box 2 and the bottom accessory storage box 1 and extend downward to fix the limit blocks 5. The limit blocks 5 are movably fitted with the bottom of the bottom accessory storage box 1.

[0030] Two sets of threaded sleeves 6 are rotatably connected to both sides of the bottom-layer accessory storage box 1 and the middle-layer accessory storage box 2 through bearings, and the inner cavity of the threaded sleeve 6 is threadedly connected to a threaded rod 7, and the top of the threaded rod 7 penetrates the bottom-layer accessory storage box 1 and the middle-layer accessory storage box 2 and extends upward. Two sets of worms 8 are rotatably connected to the bottom-layer accessory storage box 1 and the middle-layer accessory storage box 2 through bearings, and a worm wheel 9 meshing with the worm 8 is fixed on the outer side of the threaded sleeve 6. A driving assembly 10 for synchronously rotating the two sets of worms 8 is arranged inside the bottom-layer accessory storage box 1 and the middle-layer accessory storage box 2;

[0031] The driving assembly 10 is used to drive the worm 8 on both sides to rotate synchronously, and then the worm gear 9 is used to synchronously drive the two groups of threaded sleeves 6 on both sides, so that the threaded rod 7 inside the threaded sleeve 6 moves up and down synchronously, maintaining the stability of the middle-level accessory storage box 2 and the top-level tool storage box 3 during the lifting process, making it easy to retrieve accessories from the bottom-level accessory storage box 1 and the middle-level accessory storage box 2. The device can be moved to the interior of the elevator maintenance space and operated in a narrow space, avoiding the need to place the device outside and then retrieve and transfer it, wasting time, and improving the efficiency of elevator maintenance.

[0032] The driving assembly 10 includes a synchronous wheel 101 fixed to one end of the worm 8, and the outer side of the synchronous wheel 101 is connected to the synchronous belt 102 for transmission. The front ends of the bottom-layer accessory storage box 1 and the middle-layer accessory storage box 2 are provided with through grooves 103, and an extension rod 104 is fixed to the surface of the synchronous belt 102. The end of the extension rod 104 away from the synchronous belt 102 passes through the through groove 103 and extends outward. The extension rod 104 that passes through the outer sides of the bottom-layer accessory storage box 1 and the multi-layer middle-layer accessory storage box 2 can rotate the synchronous belt 102, thereby driving the synchronous wheel 101 to synchronously drive the worm 8, so that the threaded rods 7 around it move up and down at the same time to maintain the stability of lifting and lowering.

[0033] A rectangular block 11 is fixed to the top of the threaded rod 7, and four sets of limit seats 12 are fixed to the bottom of the top tool storage box 3 and the middle accessory storage box 2. The bottom of the limit seat 12 is clamped with the rectangular block 11, and the outer diameter of the limit seat 12 is the same as the outer diameter of the threaded rod 7. Through the clamping of the rectangular block 11 and the limit seat 12, the threaded rod 7 can be limited to prevent the threaded rod 7 from rotating with the rotation of the threaded sleeve 6, so that the threaded rod 7 can rotate relatively in the threaded sleeve 6 to be lifted and lowered.

[0034] A sliding groove 13 is opened at the rear of the bottom of the bottom-layer accessory storage box 1, and the limit block 5 is slidably connected to the sliding groove 13. The length of the sliding groove 13 is greater than the length of the threaded rod 7. Through the setting of the sliding groove 13, when the multi-layer middle-layer accessory storage box 2 and the top-layer tool storage box 3 move upward, the limit rod 4 and the limit block 5 can move relative to each other, leaving enough rising space.

[0035] The top of the limit rod 4 extends to the top of the top tool storage box 3 and is fixed with a fixing seat 14. The top of the fixing seat 14 is provided with an arrow in the same direction as the limit block 5. Through the setting of the fixing seat 14, it is convenient to rotate the limit rod 4 and adjust the position of the limit block 5. At the same time, the arrow can quickly identify the specific position of the limit block 5.

[0036] A cloth belt 15 is nailed to the bottom of the bottom accessory storage box 1. The cloth belt 15 extends upward from both sides and is fixed with handles. The device can be carried by the cloth belt 15 and the handles.

[0037] Cover plates 16 are hinged on both sides of the top of the top tool storage box 3, and a handle is fixed on the top of the cover plate 16. Support feet 17 are fixed on all sides of the bottom of the bottom accessory storage box 1. The setting of the cover plate 16 makes it convenient to cover the top tool storage box 3 to prevent tools from being scattered.

[0038] During specific use, the device is directly carried to the interior of the elevator, and then the maintenance personnel retrieve the corresponding accessories used for tool maintenance, rotate the fixed seat 14 to align the arrow with the position of the sliding groove 13, and then move the extension rod 104 to move in the through groove 103, and the extension rod 104 drives the synchronous belt 102 to rotate, driving the synchronous wheels 101 on both sides to rotate, and then the synchronous wheel 101 drives the worm 8 to rotate, so that the worm 8 drives the threaded sleeve 6 using the worm wheel 9. Since the limit seat 12 at the bottom of the top tool storage box 3 and the middle accessory storage box 2 is clamped with the rectangular block 11 at the top of the threaded rod 7, when the threaded sleeve 6 rotates, the threaded rod 7 is restricted by the rectangular block 11 and remains stationary, and then the threaded rod 7 rises in the rotating threaded sleeve 6, and the upper top tool storage box 3 or the middle accessory storage box 2 is lifted, providing enough space for the accessories to be retrieved and supported, so as to avoid the inability to retrieve and replace accessories in a narrow space.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
