Non-lubricated railway turnout slide plate

Abstract

The invention discloses a non-lubricated railway turnout slide plate. The non-lubricated railway turnout slide plate includes a slide plate body and a switch rail which moves on the slide plate body; the non-lubricated railway turnout slide plate further includes support blocks, support holes of which the sections are square are formed in the surfaces of the two ends of the slide plate body, the support holes are in a strip shape, the lubricative support blocks are installed in the support holes in a matched mode, the height of the lubricative support blocks is higher than that of the plate face of the slide plate body, and the bottom face of the switch rail is horizontally attached to the top faces of the lubricative support blocks. According to the prepared metal slide plate with lubricative holes and the support holes, solid lubricative materials embedded in the lubricative holes and the support holes include the lubricative support blocks and lubricative blocks, and the plate faces of the solid lubricative materials are about 1 mm higher than the plate face of the slide plate body. When a railway turnout is moved, the bottom of the switch rail directly makes contact with the lubricative materials, the situation is avoided that the bottom of the switch rail makes contact with the metal surface of the slide plate body, and a lubricating purpose is achieved.

Description

technical field [0001] The invention relates to a lubricating-free railway switch sliding bed plate. Background technique [0002] my country's high-speed rail is developing rapidly, and various disciplines and systems in it have gradually established and improved a complete set of standards.

Problems solved by technology

Only the lubrication of turnouts, although it involves daily maintenance and driving safety, but because there is no unified standard, the Eight Immortals in the electricity section of each road bureau have their own special skills, which has caused confusion and problems in the selection of products for grassroots units, and also brought about the use effect. Unsatisfactory and serious hidden dangers of turnout maintenance work

[0003] At present, the following types of turnout lubrication are mainly used: (1) aviation anti-wear hydraulic oil and waste engine oil are used. The main problems are large amount, short lubrication cycle, dust absorption, poor water resistance, and severe corrosion of rubber plates; (2) engine oil and waste engine oil. For the temporary deployment of butter, due to the poor anti-extreme pressure performance of ordinary lubricating oil, when encountering some heavy-loaded switches, some electricians will use it after mixing oil and grease according to experience, but the deployment ratio fluctuates greatly. , the dispersion is uneven, and the oil and grease are often incompatible, and it is easy to cause problems after application; (3) Imported grease is used to improve water resistance and prolong the lubrication cycle, but the price is expensive, even if it is strictly in accordance with the requirements of the supplier and The average annual cost of each sliding bed plate is as high as 720 yuan; and the dust is seriously absorbed, forming abrasive paste-like dirt, covering the lubrication defects, making it difficult to find problems in time, and will definitely corrode the rubber plate severely

[0004] Therefore, the problem of current turnout lubrication mainly lies in: corroding the rubber plate, after a period of time, this problem will become more and more prominent nationwide, and replacing the slide bed plate will consume a lot of money and labor; secondly, the existing lubrication The lubricant lubrication period is short and the water resistance is poor. The electrical workers put too much energy into oiling the sliding bed. The surface of the sliding bed is too oily, and it is difficult to find the wear marks; The degree of stagnation will occur frequently, and it is difficult to find the cause
