AI Technical Summary

Technical Problem

In the existing escalator devices for shopping carts, the pressure generated by the transmission chain in the bent parts is high, resulting in unstable transmission of the chain, short service life, and inconvenient maintenance.

Method used

A three-stage linear conveying chain structure including a lower horizontal conveying chain, an inclined conveying chain and an upper horizontal conveying chain is designed to reduce the pressure on the chain in the bending position, and ensure the stability of the shopping cart and the reliability of the escalator through the push rod structure and the rolling support structure.

Benefits of technology

It effectively reduces the pressure on the chain in the bent part, improves the service life of the chain, ensures the stable performance of the escalator, and simplifies the maintenance and maintenance process.

Abstract

The present invention belongs to the technical field of elevator products, and specifically discloses an escalator device for a shopping cart, including an escalator truss and an escalator track, wherein an upward / downward running device is respectively installed on the escalator truss, and the running device includes a driving device, and a lower horizontal conveying chain, an inclined conveying chain, and an upper horizontal conveying chain that are symmetrically arranged with the escalator truss as the center and driven by the driving device, and each chain of the conveying chain is connected with a push rod structure that forms a conflicting contact with the upright column at the rear side of the shopping cart and can drive the shopping cart to move when the elevator goes up or down, and the horizontal projection of the inclined conveying chain partially overlaps with the end positions of the upper horizontal conveying chain and the lower horizontal conveying chain adjacent thereto, and the bottoms of the lower horizontal conveying chain, the inclined conveying chain, and the upper horizontal conveying chain are all provided with a rolling support structure supported on the escalator truss. The escalator device can effectively reduce the pressure generated by the conveying chain at the bending part, ensure the stable performance during chain transmission, and effectively improve its service life. At the same time, it is easy to disassemble and assemble, which is convenient for the maintenance and maintenance of the escalator.
