AI Technical Summary

Technical Problem

Crane end beams and rollers are prone to rust when exposed to the outdoors for extended periods, which can affect normal operation. Rollers are also susceptible to damage when transporting heavy goods, which can shorten their service life.

Method used

Design a connecting device including a support plate, rollers, an oiling mechanism, and a support mechanism. The movement of the rollers and the application of lubricating oil are controlled by a hydraulic cylinder to prevent rust and reduce the pressure on the rollers. The oiling mechanism and the support mechanism respectively drip lubricating oil and provide support before and after the crane is in operation, ensuring the normal operation and service life of the rollers.

Benefits of technology

It effectively prevents rollers from rusting, ensures the normal operation of the crane, reduces roller damage, and extends service life.

Abstract

The application relates to a connecting device between crane end beams, which comprises a support plate, a plurality of rollers rotatably arranged at the front and back ends of the support plate, two mounting plates symmetrically arranged at the left and right sides of the top of the support plate, an oil storage box fixedly arranged at the top of the two mounting plates, two oiling mechanisms for smearing lubricating oil on the rollers symmetrically arranged at the front and back sides of the bottom of the oil storage box, and two supporting mechanisms for improving the stability of the support plate symmetrically arranged at the front and back sides of the top of the support plate. The support plate is supported by four L-shaped frames matched with corresponding supporting wheels, the plurality of rollers are separated from corresponding external crane end beams, the rollers are smeared with lubricating oil, the smearing dead angle is avoided, the excess lubricating oil is dropped on the external crane end beam, and rust is prevented to affect the normal operation of the crane.
