Device and method for measuring precision of elevator guide rail

Abstract

The invention relates to the technical field of measuring devices, especially a device and method for measuring the precision of an elevator guide rail. The device comprises a substrate, wherein one end of the substrate is fixedly provided with an infrared signal transmitter, and the other end of the substrate is fixedly provided with an L-shaped angle steel. The L-shaped angle steel comprises a horizontal plane for placing the elevator guide rail, and also comprises a vertical plane. The vertical plane is provided with an infrared signal receiver opposite to the infrared signal transmitter. A part, located at the rear side of the infrared signal transmitter, of the substrate is provided with a vertical column which is perpendicular to the substrate. The vertical column is provided with a horizontal rod which can slide up and down along the vertical column and is perpendicular to the vertical column. The horizontal rod is provided with a marker which can slide back and force along the horizontal rod and can carry out marking on the elevator guide rail. The device and method enables the measurement precision of the elevator guide rail to be higher through the additional arrangement of the infrared signal and automatic marker, can mark a warped part automatically, so as to facilitate the timely repair of the warped part.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a detection device and a measurement method for measuring the precision of elevator guide rails. Background technique [0002] With the progress of society and the development of science and technology, the height of floors is getting higher and higher. In order to meet the normal use requirements of high floors, the utilization rate of elevators is also getting higher and higher. The elevator is a vertical lift powered by an electric motor, equipped with a box-shaped gondola, used for multi-storey buildings to take people or carry goods. [0003] The elevator guide rail is one of the main components of the elevator. The elevator guide rail is a safe rail for the elevator to travel up and down in the hoistway. It is precisely because the elevator guide rail greatly affects the safe operation of the elevator, so the entire production process of the elevator guide rail i...

Problems solved by technology

[0004] However, the measurement accuracy of straightness and twist of most existing elevator guide rails is not accurate, resulting in a low pass rate of the final elevator guide rails, which greatly increases the repair rate of elevator guide rails in the later stage, and also brings a negative impact on the operation of the elevator. There is a great security risk
