Anti-pinching cover plate assembly for urban comprehensive pipe gallery and anti-pinching method

Abstract

The invention provides an anti-pinching cover plate assembly for an urban comprehensive pipe gallery. The anti-pinching cover plate assembly for the urban comprehensive pipe gallery comprises a coverplate, a hydraulic rod connected to the lower side of the cover plate, a hydraulic pump, a motor for driving the hydraulic pump, a reversing valve, a Hall sensor for detecting the rotation speed of the motor, a relay and an electronic control unit. The anti-pinching cover plate assembly for the urban comprehensive pipe gallery can monitor and follow the rotation speed of the motor in real time inthe cover plate opening and closing process and analyze and judge the rotation speed state of the motor in real time, once the change of the rotation speed of the motor exceeds a preset value, the movement direction of an oil cylinder is automatically changed, and real-time automatic monitoring is achieved; and in this way, the risk that materials and personnel are pinched accidentally when entering or coming out of the hole can be effectively avoided; the anti-pinching function is achieved on a feeding opening, an escape opening and a ventilation opening of the urban comprehensive pipe gallery, and the system has the features of achieving the real-time function, rapid response, high flexibility and the like.

Description

technical field [0001] The invention belongs to the field of municipal facility safety, in particular to a cover plate assembly used for urban comprehensive utility corridors. Background technique [0002] The urban comprehensive pipeline corridor is the comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. As early as 1958, Beijing had laid a comprehensive pipe corridor of more than 1,000 meters under Tiananmen Square. In 2006, the second modern comprehensive utility corridor in mainland my country was built in the west area of ​​Zhongguancun. The main line of the c...
