AI Technical Summary

Technical Problem

Existing railway bolt fastening machines require manual positioning, resulting in high labor intensity for workers.

Method used

An electric lifting frame and servo motor are used in conjunction with ball joints and ball sleeves to form a universal joint structure, which realizes the automatic connection and separation of bolts. The electric drive wheel is controlled by an inductive proximity switch to achieve automatic positioning and tightening. Combined with a telescopic extension rod and auxiliary wheels, it provides stable support and reduces the intensity of manual operation.

Benefits of technology

The automated positioning and tightening of railway bolt fastening machines has been achieved, improving positioning accuracy, reducing the labor intensity of workers, ensuring stable movement of equipment on rails, and improving work efficiency and safety.

Abstract

This invention discloses a railway bolt tightening machine, belonging to the field of railway maintenance technology. The machine includes a housing, within which a pair of electric lifting frames are fixedly connected. A servo motor is fixedly connected to the output end of each lifting frame, and an output rod is fixedly connected to the output end of each servo motor. A ball joint is fixedly connected to the end of the output rod furthest from the servo motor, and a ball sleeve is fitted over the ball joint. A connecting rod is fixedly connected to the lower end of the ball sleeve. This invention controls the start and stop of the electric drive wheel using a proximity switch. When the proximity switch approaches the bolts before and after the bolt to be tightened, the electric drive wheel stops. The lifting frames then drive the servo motor to descend, causing the sleeve to fit over the bolt. The servo motor drives the sleeve to rotate, tightening the bolt. The entire process is automatic, eliminating the need for manual positioning, greatly improving positioning accuracy and reducing the labor intensity of workers.
