Dustproof guide sleeve

Abstract

The invention relates to a dust-proof guide sleeve, comprising a guide sleeve body, a detection device is arranged inside the guide sleeve, the detection device is connected to a data processing host through a wired connection or a wireless connection, and the detection device is used for Detect the relative gap between the guide sleeve and the guide column so as to obtain the wear status information of the guide sleeve and transmit it to the data processing host, and the data processing host will transmit the processed data to the host display screen, and the host display screen will The data and reference suggestions processed by the data processing host are displayed on the display screen of the host. Since the guide sleeve of the present invention has a built-in detection device, it is used to detect the relative vibration of the guide column and the guide sleeve in the working state, measure and calculate the relative gap, thereby obtain the wear state of the guide sleeve, and give reference suggestions.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a dust-proof guide sleeve installed on a grinding vehicle. Background technique [0002] China has imported URR48-4, RR48HP-4, PGM-48 rail grinding trains and RGH20C turnout grinding trains from abroad since the end of 1980s. They have been operated on several main lines of the whole road with good results. At present, many companies in many countries in the world are constantly developing and developing rail grinding equipment, and have manufactured various types of rail grinding trains. The most used model in my country's railway sector is the PGM-48 line designed and manufactured by the American HTT company. Grind trains, but the GMC-96 grind car is similar to this. [0003] The grinding operation device is the main working mechanism of the grinding train, and the grinding operation device is an integral mechanism hoisted on the bottom of the grinding train, als...

Problems solved by technology

[0004] 1. The guide column and the guide sleeve designed by the original car are lubricated with butter, and the guide column is exposed outside. When grinding, the abrasive debris directly splashes on the guide column covered with butter, and it is easy to accumulate on the surface of the guide column for a long time;

[0005] 2. The guide column and the guide sleeve of the connecting part of the grinding motor, the dust-proof rings at both ends and the guide sleeve are interference fit, and the position is limited only by the interference force. When the motor moves up and down with the guide sleeve, it often occurs The phenomenon that the dust-proof ring is carried out. Once the dust-proof ring is separated from the guide sleeve, it will not be able to prevent dust. The iron filings will enter the guide sleeve and scratch the surface of the guide column, affecting the normal up and down movement of the guide column, and the motor will go up and down quickly. The operation is hindered or even stuck, which eventually affects the normal work of the rail grinding vehicle;

[0006] 3. The easier it is to accumulate iron filings, the more frequent it is to scrub and maintain, and then re-grease. Repeated work is a vicious circle, which not only increases the workload of equipment maintenance personnel, but also wastes a lot of butter

However, after the guide column and the guide sleeve of the guide sleeve wear each other, the equipment maintenance personnel cannot see the wear state of the guide sleeve, and cannot know whether it is necessary to repair or replace the guide sleeve, so that the reliable operation of the equipment cannot be guaranteed.
