Self-lubricating slide plate

Abstract

The invention relates to a self-lubricating slide plate. The self-lubricating slide plate comprises a slide plate body, a sliding plate and tongue rails; the slide plate body is fixed to a rubber pad in an assembled mode, and the rubber pad is placed on a switch tie according to the position of a nail hole; a self-lubricating zone is arranged in the middle of the surface of the sliding plate; a steel ball assembly is embedded in the self-lubricating zone, the steel ball assembly is embedded in the surface of the sliding plate through the interference fit and internally embedded with steel balls, when installed, the steel ball assembly is internally coated with lubricating grease so that a self-lubricating function is achieved in rolling of the steel balls, and the upper parts of the steel balls all protrude the surface of the sliding plate; the tongue rails are placed above the steel balls in the self-lubricating zone; and a basic rail is arranged on one side of the top surface of the slide plate body, and a bottom rail rubber pad is sandwiched between the bottom of the basic rail and the top surface of the slide plate body. The self-lubricating slide plate is simple in structure, low in manufacturing cost, convenient to install, low-technological demand in manufacturing, installation, use environment and maintenance, convenient to maintain, capable of effectively reducing the conversion failure and the amount of maintenance workload and capable of improving maintenance efficiency.

Description

technical field [0001] The invention relates to facilities for railway lines, in particular to a self-lubricating sliding bed board. Background technique [0002] A turnout is a line connection device that enables locomotives to transfer from one track to another, and the transfer from one track to another is realized through the conversion of the tip rail and the core rail. During the conversion process, The friction between the rail and its contact (sliding bed) is inevitable, resulting in resistance. How to reduce the resistance and easily realize the conversion of the turnout is one of the long-term research topics in the research and development of turnout products. [0003] At present, the main ways to reduce the conversion resistance of the point rail and the center rail of the turnout are: applying lubricating oil on the surface in contact with the rail bottom and the sliding bed, and setting rollers on the side of the sliding bed, etc. Applying lubricating oil re...

AI Technical Summary

Problems solved by technology

Applying lubricating oil requires a lot of maintenance and maintenance work, and the resistance reduction is not obvious; while setting rollers requires higher design requirements for the sliding mattress pad, and it is necessary to add a roller transposition installation structure on the side of the table, and the design of the entire pad More complicated, and the cost of the roller device is higher

In addition, from the perspective of the cause of the conversion failure, in addition to the foreign matter on site, the lack of lubrication is also one of the main factors
