Shopping cart conveying system

Abstract

The invention provides a shopping cart conveying system. A cart comprises a shopping frame, shopping supports, front wheels and rear wheels. The shopping cart conveying system comprises a connecting assembly, a support and cart conveying units. The connecting assembly comprises a cross rod connected with the middles of the shopping supports and two support rods connected with the cross rod; and a clamping portion is formed at the other end of each support rod. The cart conveying units are arranged on the support. Each cart conveying unit comprises a base plate, a guide rail, an anti-bouncing cover plate, two chains, conveying guide blocks and a driving component, wherein each base plate is arranged on the support, and a support portion is arranged in the middle of each base plate; each guide rail is arranged on the upper surface of the corresponding support portion, and limiting grooves are formed in the two side walls of each guide rail; each anti-bouncing cover plate comprises a support portion and two limiting anti-bouncing portions, and two limiting anti-bounding cavities are formed by every two limiting anti-bouncing portions and the corresponding guide rail; every two chains are arranged in the corresponding limiting grooves; and the conveying guide blocks are arranged on the outer wall of a chain plate outside the chains. By means of the conveying system, rollover accidents occurring in the conveying process can be effectively prevented; stability is good; steady operation is achieved; multiple carts can be conveyed at the same time; conveying efficiency is high; and the shopping cart conveying system is reasonable in structural design, low in production cost and good in economic benefit.

Description

technical field [0001] The invention belongs to the field of shopping equipment, and in particular relates to a trolley transport system for shopping, which is used for transporting trolleys between low positions and high positions, especially for transporting trolleys between two floors, and can also be used for horizontal transport. Background technique [0002] Shopping trolleys are commonly found in large supermarkets or large shopping malls and stores. They generally refer to a kind of shopping equipment we use for shopping in supermarkets, shopping malls or stores. They are an indispensable tool in our lives. Shopping carts are used when shopping in supermarkets , On the one hand, it can increase the demand of buyers, and on the other hand, it can increase the transaction volume of sellers, which can be described as a win-win result that kills two birds with one stone. [0003] The transportation of trolleys between different floors mainly includes the following method...

AI Technical Summary

Problems solved by technology

[0004] 1. Use elevators to transport. The advantage of this method is that it can realize the transport of trolleys regardless of the number of floors, but the disadvantage is that the capacity of the elevator is limited, and the number of trolleys transported each time is limited, so it is impossible to transport a large number of trolleys;

[0005] 2. Use ramps to transport. The advantage of this method is that it can transport a large number of trolleys, but the disadvantage is that the inclination angle of the ramp should not be too large, and the slope needs to be gentle, otherwise it is easy to roll over, and the gentle slope will lead to too long a ramp distance , takes up too much space, which is not conducive to rational use of space

However, in this patent, stoppers are set between the chains, hook grooves are arranged on the stoppers, and the conveyor chain hooks the crossbar on the trolley through the hook grooves to drive the trolley to move. If the fit is not strong enough, decoupling is prone to occur, causing the trolley to overturn due to the rearward center of gravity during transportation on a slope
