Linear sliding rail lubrication system of shielding door

Abstract

The invention belongs to the technical field of sliding rail lubrication, and particularly relates to a linear sliding rail lubrication system of a shielding door. The system comprises a lamp box metal plate frame, a left fixed door, a right movable door and a left movable door, wherein the left fixed door and the right fixed door are fixedly connected to the left end and the right end of the interior of the lamp box metal plate frame correspondingly. Whether an oil tank is full or not is determined by monitoring the oil pressure, so that maintenance personnel directly refuel the self-lubricating oil tank without disassembling a housing, and when the pressure is equal to a certain value, early warning can be carried out in advance, so that the dry grinding of the surface of a linear rail caused by untimely refueling is avoided, the overall use precision of equipment is improved, and the service life of the equipment is prolonged; through the cooperation of the self-lubricating oil tankand a tubular oil tank, lubricating oil can be injected into a linear guide rail and a sliding block, and the lubricating oil is convenient to supply; and through the cooperation of a pipeline pressure sensor and a state indicator lamp, the oil pressure in the tubular oil tank can be monitored in real time, and a prompt can be given when the oil pressure is small, so that the lubricating oil canbe supplied in time.

Description

technical field [0001] The invention relates to the technical field of slide rail lubrication, in particular to a linear slide rail lubrication system for shielded doors. Background technique [0002] The screen door refers to the glass curtain wall on the platform that surrounds the subway platform and the train boarding and landing space. When the train arrives, the electric door on the glass curtain wall is opened for passengers to get on and off the train. [0003] The opening of the screen door adopts the transmission form of screw or synchronous toothed belt plus linear guide rail. The required number of movement switches is not less than 1 million times, and the service life is not less than 8 years. Therefore, for the above-mentioned applications, the lubrication of the line rail is particularly important, and the use environment of the screen door is in a relatively flat area, and it is impossible to directly fill the oil tank of the line rail slider.
