Escalator device for shopping cart

Abstract

The invention belongs to the technical field of elevator products, and particularly discloses an escalator device for a shopping cart. The device comprises an escalator truss and an escalator track, wherein upward moving / downward moving running device are installed on the escalator truss separately, the running devices comprise driving devices, lower horizontal conveying chains, inclined conveyingchains and upper horizontal conveying chains, the lower horizontal conveying chains, the inclined conveying chains and the upper horizontal conveying chains are driven by the driving devices to be symmetrically arranged with the escalator truss as the center, each chain of the conveying chains is connected with a corresponding push rod structure which makes contact with a vertical column on the rear side of the shopping cart in an abutting mode and can drive the shopping cart to move when an escalator moves upwards or downwards, projections of the inclined conveying chains in the horizontal direction partially coincide with the ends of the upper horizontal conveying chains and the ends of the lower horizontal conveying chains adjacent to the inclined conveying chains correspondingly, androlling supporting structures supported on the escalator truss are arranged at the bottoms of the lower horizontal conveying chains, the bottoms of the inclined conveying chains and the bottoms of theupper horizontal conveying chains correspondingly. The escalator device can effectively reduce pressure generated by the conveying chains at bent parts, ensures the stability of the chains during transmission, effectively prolongs the service life of the device, is convenient to disassemble and assemble, and facilitates the maintenance of the escalator.

Description

technical field [0001] The invention belongs to the technical field of escalator products, in particular to an escalator device for a shopping cart. Background technique [0002] In the prior art, an escalator device for a shopping cart is generally driven by a flexible endlessly rotating chain. For example, the publication number is CN111056415A, and the name of the invention is a special elevator for shopping carts. The special elevator includes a steel frame And the apron plate arranged on the steel frame also includes a support plate for supporting the wheels of the shopping cart; a transmission device for pushing the handle of the shopping cart to move along the support plate; the transmission device includes a transmission chain, and the The transmission chain is connected with a locking mechanism for holding the handle of the shopping cart, a sprocket arranged on the transmission chain, and a power component for driving the sprocket. The chain links of the transmissi...

AI Technical Summary

Problems solved by technology

The chain links of the transmission chain used in this special elevator can be bent straight and horizontally, but its obvious disadvantage is that the service life of the chain is not long, because the chain will produce abnormal noise and vibration during the transmission process. In the bending part of the chain belt, the chain links are squeezed and deflected, and in the inclined section of the shopping cart up and down, the locking mechanism installed on the chain will be simultaneously subjected to a force perpendicular to the chain plate and a force parallel to the chain plate. The force of the chain plate will cause fatigue damage to the chain, and this special chain has the disadvantages of high processing cost and difficult maintenance
