AI Technical Summary

Technical Problem

The existing cable lubrication devices fail to effectively clean up dust and debris on the outer surface of the cable when applying lubricating oil, which affects the lubrication effect and is not very automated and requires manual operation.

Method used

A crane cable lubrication device is designed, including a combination mechanism of a rotating shaft, a moving shaft, a worm section, a limit ring and a return spring, which is used to clean the outer surface of the cable and achieve higher automation control through the cooperation of ball valve switch, rack, electric push rod and friction block.

Benefits of technology

It realizes automatic cleaning of dust and debris on the outer surface when the cable is rolled up, avoid affecting the lubrication effect, and more efficiently manages the injection and use of lubricant fluid through automated control, improving the degree of work automation.

Abstract

The utility model discloses a crane cable lubricating device, which relates to the technical field of cable lubrication and comprises a device body and a rack, a second cavity is arranged in the device body, a rotating shaft is rotatably mounted on the inner bottom wall of the second cavity, a groove is arranged at the top of the second cavity, and a deep groove ball bearing is mounted in the groove. A first limiting ring is fixedly mounted in the deep groove ball bearing, and a moving shaft is slidably inserted into the first limiting ring. A lubricating liquid injection pipe is inserted into the middle of the device body, a first cavity is formed in the device body, and a communicating hole is formed in the inner top wall of the first cavity. According to the combined mechanism for cleaning the outer surface of the cable, the rotating shaft, the moving shaft, the deep groove ball bearing, the first limiting ring and the first reset spring are arranged in a matched mode, the combined mechanism for cleaning the outer surface of the cable is provided, the mechanism only plays a role when the cable is collected, and the lubricating effect is prevented from being affected; and through cooperative arrangement of a ball valve switch, a rack, a first cavity, an electric push rod, a friction block and a second reset spring, more perfect automation is achieved.
