Anti-reverse detection device for escalator or moving walk and installation method thereof

Abstract

The invention provides an anti-reversal detection device of an escalator or a moving pavement. The device comprises a metal chain wheel, a probe support, two probe supports and a detection system, wherein the metal chain wheel is provided with a plurality of teeth which are intermittently distributed along a circumferential direction, the probe support is arranged at one side of the metal chain wheel and is fixed on a side girder, the two metal probes are arranged on the probe support and are respectively opposite to the sides of the two adjacent teeth on the metal chain wheel, and the detection system is electrically connected with the two metal probes; the probe support comprises a mounting surface, a support surface and a connecting surface, wherein the metal probes are fixed by the mounting surface, the support surface is parallel to the axial direction of the metal chain wheel and is fixedly connected with the side girder, the mounting surface is provided with two mounting holes corresponding to adjacent teeth one by one on the metal chain wheel, and the two metal probes are correspondingly fixedly arranged in the two mounting holes one by one. The invention further provides a mounting method of the anti-reversal detection device, wherein the probe support is located by a tooling, so that the metal probes are more accurate in mounting position and are very convenient to mount.

Description

technical field [0001] The invention relates to an anti-reversal detection device of an escalator or a moving walkway and an installation method thereof. Background technique [0002] The standard of the People's Republic of China GB16899-2011 "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks" stipulates that escalators and moving walks should automatically stop running before the running speed exceeds 1.2 times the nominal speed, and run when the steps and pedals change the regulations. Automatically stop running when in the direction. Therefore, it is required to install an anti-reverse detection device on the escalator or moving walk to monitor the running direction of the metal sprocket of the escalator or moving walk. The anti-reverse detection device in the prior art includes two metal probes installed in the radial front of the metal sprocket and a detection system connected with the metal probes. The two metal probes respecti...

AI Technical Summary

Problems solved by technology

The anti-reverse detection device in the prior art includes two metal probes installed in the radial front of the metal sprocket and a detection system connected with the metal probes. The two metal probes respectively correspond to the detection of two adjacent teeth on the metal sprocket. , but the anti-reversal detection device of this kind of structure needs to set up a horizontal bracket between the truss brackets on both sides of the escalator or moving walk, and then install the metal probe on the horizontal bracket through the probe bracket. Not only the structure is complicated, but also the installation of the probe requires Adjusting the position of the probe relative to the gear requires more man-hours to adjust the position of the probe

If the position of the metal probe relative to the gear is inaccurate, it is easy to cause the detection of the rotation direction of the gear to fail, and it is impossible to judge whether the escalator or moving walk is reversed.
