Driving force and speed deviation detection device for escalator handrail belt

Abstract

The invention relates to the technical field of escalator detection, and discloses a driving force and speed deviation detection device for an escalator handrail belt. The driving force and speed deviation detection device for the escalator handrail belt comprises a rack, the handrail belt, a rod body I and a bearing I, wherein a rod body II is further fixedly connected to the rack; a wheel disc Iis rotationally connected to the rod body II; a speed difference measuring device is arranged at the left side of the wheel disc I; a driving force measuring device is arranged at the right side of the wheel disc I; the handrail belt rotates to drive a disc I to rotate to drive a disc II attached to the disc I to move; the small circle part of a plate body I pushes a rod body V to move leftwards;the rod body V pushes a sliding block I to move leftwards; the sliding block I generates heat in the leftward moving process; the heat is conducted to air at the left side through a heat conduction plate I, the air at the left side of a cylinder I is heated to expand in volume, the expanded air pushes a ball body to slide upwards in the cylinder, and the position of the ball body is obvious, so that measurement convenience is improved; and due to simple mechanical structure connection, the device is stable, reliable and accurate in measurement.

Description

technical field [0001] The invention relates to the technical field of escalator detection, in particular to an escalator handrail driving force and speed deviation detection device. Background technique [0002] As a common carrier of force in public places, escalators provide convenience for passengers and are widely used. However, different Changhes require different escalators. Professionals are required to adjust the speed of the escalator according to the scene. When the escalator is overhauled, it is necessary to Measure various indicators of the escalator, including the driving force of the elevator and the deviation of the running speed from the set speed, and adjust it in time. However, most of the existing measuring devices are electronic devices, which are expensive, unstable and difficult to install. The limitations of the measurement bring inconvenience to the measurement, so it is necessary to improve the existing measurement equipment to meet the needs of ele...
