Shopping cart conveying system

Abstract

The invention provides a shopping cart conveying system. A cart comprises a shopping frame, two shopping supports, front wheels, rear wheels, two guide rods, a connecting rod, a supporting rod, a conveying system an upstream conveying unit, a downstream conveying unit, two sets of limiting rods, two sets of chains and a plurality of partition blocks, wherein the upper ends of the two guide rods are connected to the two side edges of the shopping frame, and the lower ends of the two guide rods are connected to support rods of the two shopping supports; the two ends of the connecting rod are connected with the ends of the support rods; the upper end of the supporting rod is arranged on the connecting rod in a sleeving mode; the conveying system comprises a support; the upstream conveying unit and the downstream conveying unit each comprise a bottom plate; the two sets of the limiting rods are laid onto the upper surfaces of the bottom plates; the two sets of the chains arranged in parallel with the length direction of the slopes of the bottom plates; two driving wheels are engaged with the inner sides of the two ends of each chain correspondingly; the driving wheels are connected with driving rods; the driving rods are perpendicular to the slopes; the other ends of the driving rods are connected with driving motors; the partition blocks are arranged on the outer walls of the twochains at intervals in a protruding mode, and the other ends of the partition blocks are matched with the corresponding guide rods to conduct conveying driving on the cart along the slopes between thelow position and the high position. The conveying system can effectively protect the cart against an overturn accident when the cart is conveyed from the high position and the low position.

Description

technical field [0001] The invention belongs to the field of shopping equipment, and in particular relates to a trolley conveying 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

The delivery system provided by this patent, when the shopping cart just enters, because the bottom is inclined, the shopping cart will lose its center of gravity, go down quickly and lose control, and the shopping cart will touch the running chain stopper when it slides down. Too intense, it's the shopping cart that doesn't run smoothly

[0009] Chinese patent application number 99807340.7 discloses a trolley transmission system, the shopping cart can enter the transmission system in parallel and smoothly, and the drive chain stopper can also well realize the back and forth operation of the trolley between the upper and lower parallel planes and the middle inclined section, but Its chain structure and arrangement are complicated, and the production cost is high
