Escalator and moving walk comb safety protection detection device and detection method

Abstract

The invention discloses a safety protection detection device and a detection method of comb plates on an automatic escalator and an automatic sidewalk. The detection device is characterized in that a wedge-shaped inserting block is horizontally arranged, wing plates are horizontally arranged on the two sides of the wedge-shaped inserting block, detachable upright push plates are arranged on the wing plates, and the wedge-shaped inserting block and the wing plates are placed on a stair tread and can run along with stairs; the wedge-shaped inserting block running along with the stairs is inserted between the comb plate and the stair tread to simulate the insertion of foreign matter to detect the vertical movement of the comb plate, and the upright push plates running along with the stairs are utilized to horizontally push the comb plate to detect the horizontal movement of the comb plate; vertical pressure sensors are distributed on the wedge surface of the wedge-shaped inserting block, and horizontal pressure sensors are distributed on the plate surface of the upright push plates; and detection signals of a vertical displacement laser distance measuring instrument and a horizontal displacement laser distance measuring instrument are used for obtaining displacement values generated by the comb plate and a mounting plate of the comb plate in the vertical direction and in the horizontal direction. According to the detection device and the detection method, the detection and inspection work of the automatic escalator and the automatic sidewalk can be effectively carried out.

Description

technical field [0001] The invention relates to an escalator / moving walk comb safety protection detection device and a detection method thereof. Background technique [0002] With the rapid construction of public facilities in my country, the use of escalators / moving walks is increasing, and safety accidents are also on the rise. On the step tread surface of the escalator and the tread surface of the moving walk, there are tooth grooves meshing with the comb teeth of the comb tooth plate along the running direction. GB16899-2011 "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks" and TSGT7005-2012 "Rules for Elevator Supervision and Periodic Inspection - Escalators and Moving Walks", the meshing of the comb teeth of the comb plate and the tooth grooves of the pedal surface There are clear requirements for depth and clearance. When a foreign object is caught, the comb-tooth plate will be squeezed to a certain extent, resulting in a re...

Problems solved by technology

The push rod of this scheme can withstand the comb plate, and the guide can move with the steps to the direction close to the comb plate. The tension meter can detect the force between the comb plate and the steps, so as to judge the flexibility of the comb plate , but it still has problems in the following aspects: First, it can only apply horizontal thrust to the comb plate, so that the comb plate moves backward, thereby triggering the parking switch installed horizontally; it cannot apply upward force to the comb plate, The comb-tooth plate cannot be moved upwards, and the vertically installed parking switch cannot be triggered, so the scope of application is limited; second, when the comb-tooth plate touches the top plate assembly, the entire detection device cannot It is possible to flip clockwise; the third is that the detection force of the device uses the detection method of the spring balance, which requires the operator to manually record the detection data; the fourth is that it cannot detect the displacement of the comb plate after the force is applied
