Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An automatic oiling device for the drive wheel bearing of a detachable passenger ropeway includes a set of fixed frames 1. A retraction mechanism 2 is provided on the inner side of the fixed frames 1 for retracting the oiling nozzle. The retraction mechanism 2 includes:

[0025] The lifting unit 21 includes a mounting box 211 fixedly installed inside the mounting frame 1. A lead screw 214 is rotatably installed inside the mounting box 211. A drive ear 215 is rotatably installed on the surface of the lead screw 214. A fixing ring 216 is fixedly installed at one end of the drive ear 215. An oil injector 217 is fixedly installed inside the fixing ring 216. In this embodiment, a sliding ear 213 is fixedly installed on the side of the fixing ring 216 away from the drive ear 215. A limit rod 212 is fixedly installed inside the mounting box 211. The sliding ear 213 slides on the surface of the limit rod 212 to limit the movement of the fixing ring 216.

[0026] The drive assembly 3 drives the lead screw 214 to rotate, which in turn drives the drive ear 215 to move up and down, thereby raising and lowering the oil injector 217 on the limit rod and realizing the retraction and extension of the oil injector nozzle at the bottom of the oil injector 217; the sliding ear 213 slides along the limit rod 212 to constrain the movement trajectory of the fixed ring 216 and prevent radial displacement of the oil injector 217 during the raising and lowering process.

[0027] A dustproof unit 22 is disposed at the bottom of the mounting box 211 and is used to prevent dust from entering the mounting box 211. In this embodiment, the dustproof unit 22 includes a fixed tube 221 fixedly installed at the bottom of the mounting box 211. A threaded sleeve 223 is rotatably installed on the surface of the fixed tube 221, and a fan-shaped dustproof cover 222 is fixedly installed between the fixed tube 221 and the inner convex ring of the threaded sleeve 223. The fan-shaped dustproof cover 222 is installed and removed through the threaded engagement between the threaded sleeve 223 and the fixed tube 221. When closed, it covers the bottom opening of the mounting box 211. The fan-shaped dustproof cover 222 is made of rubber and is divided into multiple fan-shaped cover plates, which are composed of a circumferential array of multiple cover plates. When the fan-shaped cover plates are closed, they effectively prevent external dust from entering the mounting box 211.

[0028] In this embodiment, a spring tube 218 is fixedly installed on the top of the oil injector 217 for use in conjunction with the oil injector 217 to lift and inject oil.

[0029] The spring tube 218 flexibly connects the oil injector 217 to the external oil circuit and automatically extends and retracts when the oil injector nozzle is raised or lowered. The upper end of the spring tube 218 is sealed to the internal oil circuit of the oil injector (217) through a hard pipe interface, and the lower end of the spring tube 218 is connected to the external oil supply pipeline through a hard pipe interface.

[0030] In this embodiment, the drive assembly 3 includes a fixed base 32 fixedly installed on the top of the inner cavity of the mounting box 211. A worm gear 33 is rotatably installed on one side of the fixed base 32. A motor 34 is fixedly installed on the left side of the mounting box 211, and one end of the worm gear 33 passes through the mounting box 211 and is fixedly connected to the output end of the motor 34.

[0031] Motor 34, model KV3SF-8521F-WR, is electrically connected to an external power source and is operated by a human-controlled control panel.

[0032] In this embodiment, a worm gear 31 is fixedly mounted on the surface of the lead screw 214, and the worm gear 31 is meshed with the worm 33.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, firstly, the motor 34 drives the worm gear 33 to rotate, which in turn drives the worm wheel 31 to rotate. The worm wheel 31 then drives the lead screw 214 to rotate, which in turn drives the drive ear 215 to move downward. The drive ear 215 then drives the fixed ring 216 to move downward synchronously, which in turn drives the oil injector 217 to move downward. Simultaneously, the fixed ring 216 drives the sliding ear 213 to slide on the surface of the limit rod 212. The oil injector 217's bottom oil nozzle passes through the central hole of the fan-shaped dust cover 222 and is precisely inserted into the oil injection hole of the drive wheel bearing. The external grease supply system is activated, and grease is input into the oil injector 217 through the spring tube 218. The internal pump of the oil injector works, and grease is sprayed out from the bottom oil nozzle to achieve oil injection.

[0035] Then, the motor 34 runs in reverse, causing the fixed ring 216 to move upward. The fixed ring 216 drives the oil injector 217 to move upward synchronously, so that the oil injector nozzle at the bottom of the oil injector 217 is retracted into the installation box 211. The threaded sleeve 223 is rotated to separate it from the fixed tube 221, making it convenient to disassemble and assemble the fan-shaped dust cover 222.
