[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a traction passenger elevator drive structure, including a traction machine base 1 installed inside the passenger elevator shaft, a traction machine wheel 2 fixed at one end of the traction machine base 1, a detachable protective mechanism sleeved on the surface of the traction machine wheel 2 at one end of the traction machine base 1, and a hoisting mechanism at the top of the traction machine base 1. The detachable protective mechanism includes a detachable side plate assembly and a connecting top plate.

[0022] In this embodiment, preferably, the detachable side plate assembly includes side plates 100 symmetrically arranged at one end of the traction machine base 1 and on both sides of the traction machine wheel 2, and connecting grooves 101 symmetrically opened on both sides of one end of the traction machine base 1. A connecting block 102 is fixed to the end of the side plate 100, and the connecting block 102 is engaged with the connecting groove 101 to facilitate the connection of the side plate 100 with the traction machine base 1.

[0023] In this embodiment, preferably, the end of the connecting block 102 is provided with a guide groove 200, and the side plate 100 is symmetrically fixed with guide blocks 201, which are engaged with the guide groove 200.

[0024] In this embodiment, preferably, the guide groove 200 has symmetrically opened limit grooves 300 at both ends, and the guide block 201 has an internal groove 301 on one side. The internal groove 301 is provided with a limit block 302. The limit block 302 is engaged with the limit groove 300 to limit the guide block 201 and the guide groove 200.

[0025] In this embodiment, preferably, a through hole 400 is provided through the interior of the built-in groove 301, and a pull rod 401 is provided on the other side of the guide block 201, which passes through the interior of the through hole 400 and is fixedly connected to the limiting block 302. A telescopic spring 402 is sleeved on the surface of the pull rod 401, and a pull button 403 is provided on the other side of the guide block 201 and is fixedly connected to the pull rod 401, so as to facilitate pulling the limiting block 302 into the interior of the built-in groove 301.

[0026] In this embodiment, preferably, the connecting top plate includes a top plate 500 disposed at the top of the traction machine wheel 2 and connected to the side plate 100. The bottom end of the top plate 500 is symmetrically provided with a docking groove 501, and the top end of the side plate 100 is symmetrically fixed with a docking block 502. The docking block 502 is engaged with the docking groove 501. The two sides of the docking block 502 are symmetrically provided with slots 503. The inner wall of the docking groove 501 is symmetrically fixed with a buckle 504. By engaging the buckle 504 with the slot 503, the top plate 500 and the side plate 100 can be connected in a limited position.

[0027] In this embodiment, preferably, the hoisting mechanism includes hoisting rings 600 symmetrically arranged at the top of the traction machine base 1. The top of the traction machine base 1 is symmetrically provided with screw holes 601. The bottom end of the hoisting ring 600 is fixed with a screw rod 602. The screw rod 602 is screwed into the screw hole 601 to facilitate the assembly of the hoisting ring 600 with the traction machine base 1.

[0028] The working principle and usage of this utility model are as follows: When it is necessary to inspect the traction sheave 2, first lift the top plate 500, causing it to separate the docking block 502 from the docking groove 501, and squeeze the buckle 504 away from the slot 503. This allows the top plate 500 to be separated from the top of the traction sheave 2 and the side plate 100. Then, pull the pull button 403 inside the guide groove 200, causing it to slide the pull rod 401 inside the through hole 400. At the same time, it causes the limiting block 302 to retract from the limiting groove 300 and into the inner groove 301. When the internal compression spring 402 deforms, the positioning of the connecting block 102 can be released. Then, the side plate 100 is pulled outward, causing the connecting block 102 to exit from the inside of the connecting groove 101, and causing the guide groove 200 to separate from the guide block 201, thus completing the disassembly work. This facilitates the inspection, maintenance, or lubrication of the traction machine wheel 2. When installing the traction machine base 1, the lifting ring 600 can be fixedly connected to the screw hole 601 by screw rod 602. Then, the traction machine base 1 can be lifted and moved by using a hoist connected to the lifting ring 600.

[0029] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
