Self-lubricating slide plate and manufacturing method thereof

Abstract

The invention discloses a self-lubricating slide plate and a manufacturing method thereof. The self-lubricating slide plate comprises a bottom plate, an iron base, a platen, an iron guide, an anti-friction plate and countersunk screws. The anti-friction plate is embedded into a slot in the surface of the platen and fixed onto the upper surface of the platen through the countersunk screws; the iron base, the platen and the iron guide are welded on the bottom plate. The self-lubricating slide plate reduces switching resistance and displacement insufficiency of a point rail, ensures normal working of a point switch and maintains good linearity for a turnout, enables a train to safely pass through the turnout, effectively reduces the construction cost and the maintenance cost, achieves high reliability, releases the labor load of working personnel for daily maintenance and reduces environmental pollution.

Description

technical field [0001] The invention relates to a facility for railway lines, in particular to a turnout sliding bed plate with self-lubricating function for high-speed railway line turnouts and a manufacturing method thereof. Background technique [0002] At present, in order to reduce the pulling force of the switch rail, the switch with a speed of 200 kilometers per hour and the high-speed switch with a speed of more than 250 kilometers per hour are equipped with roller sliding bed plates at intervals on the movable part of the switch rail, changing the sliding friction into rolling friction, which can effectively reduce the switching resistance of the switch rail. However, due to the high price of the roller device, a set of roller device is about 3,000 yuan. Even for the shorter No. 12 turnout, 6 sets of roller devices are required, and for No. 42 turnout, 24 sets of roller devices are required to reduce friction. The adoption of the roller device increases the cost of ...

[0002] At present, in order to reduce the pulling force of the switch rail, the switch with a speed of 200 kilometers per hour and the high-speed switch with a speed of more than 250 kilometers per hour are equipped with roller sliding bed plates at intervals on the movable part of the switch rail, changing the sliding friction into rolling friction, which can effectively reduce the switching resistance of the switch rail. However, due to the high price of the roller device, a set of roller device is about 3,000 yuan. Even for the shorter No. 12 turnout, 6 sets of roller devices are required, and for No. 42 turnout, 24 sets of roller devices are required to reduce friction. The adoption of the roller device greatly increases the cost of the turnout, and the roller device is not conducive to the popularization and application of the lower price turnout

[0003] At the same time, in the high-speed turnouts with a speed of 250 kilometers per hour and 350 kilometers per hour, except for roller sliding bed plates at intervals on the movable part of the switch rail, anti-friction coatings are provided on the surface of other sliding bed plates to further reduce the conversion resistance. However, the adoption of these measures makes turnout cost increase
