Abstract

The invention discloses a deviation detection device for a shopping cart automatic ladder conveying chain. The device comprises a fixed mounting frame, a rotating shaft, two vertical rods fixed to therotating shaft, a rotating disc fixed to the rotating shaft and a travel switch. The mounting frame comprises a rotating shaft supporting seat; the rotating shaft is rotatably mounted in the rotatingshaft supporting seat; an axial limiting piece is also arranged between the rotating shaft and the mounting frame; the two vertical rods are symmetrically arranged on the two sides of the longitudinal section of the conveying chain; the outer peripheral surface of the rotating disc is provided with a limiting groove; and a travel switch detecting contact is embedded in the limiting groove. When the conveying chain deviates, at least one vertical rod is located on the moving path of the conveying chain, and during conveying of a shopping cart automatic ladder, the conveying chain rotates by pushing the rotating disc on the rotating shaft through one vertical rod. The travel switch detecting contact detects displacement changes to control the shopping cart automatic ladder to stop. When the conveying chain deviates, the device can quickly detects deviations and control the shopping cart automatic ladder to stop, and the safety is high.

Description

technical field [0001] The invention relates to the field of elevator operation monitoring devices, in particular to an offset detection device for a shopping cart escalator conveying chain. Background technique [0002] A shopping cart escalator is a mechanical device that uses a conveyor chain to drive a shopping cart up or down. After long-term use, the mechanical parts will inevitably wear out, the assembly accuracy will drop, and the conveyor chain will easily shift or even derail, causing damage to the equipment and injury to the operator. Contents of the invention [0003] In order to solve the above problems, the present invention provides an offset detection device for the conveyor chain of the shopping cart escalator. When the conveyor chain deviates, it can quickly detect the displacement change of the conveyor chain, control the parking of the shopping cart escalator, and improve safety. sex. [0004] Technical solution: the present invention provides an offs...
