[0002] The shopping cart elevator is a new equipment developed in recent years. Generally, the elevators in large supermarkets use flat elevators. Consumers can push shopping carts up and down. This type of flat elevator takes up a lot of space and requires a long installation distance. The use is limited. For most shopping malls with limited space and distance, two shopping cart elevators are installed between the two stair elevators. The shopping cart elevator can make the shopping cart go forward synchronously along the elevator track with the step elevator, which meets the requirements of use. At the same time, it also has the characteristics of separation of people and vehicles, safe and reliable. With the application of the shopping cart elevator, the matching shopping cart special elevator The export transmission device is a necessary link, and the manufacturing and assembly is very important. The traditional assembly method often causes scratches on the interference fit of the rolling bearing, or even scraps the parts, and the assembly quality is unstable.

Embodiment Construction
[0016] This example is for figure 1 , figure 2 , image 3 The special elevator exit conveying device for the shopping cart in the shopping cart is assembled: the steps are as follows:
[0017] The first step, interference fit parts heating and cooling treatment: put the left conveyor pulley (24), left conveyor pulley (26), narrow pulley (13), narrow pulley (15), right conveyor pulley (16), right conveyor pulley (18), the driving gear (21), the driven gear (22), put them into an oil bath with a temperature of 80°C, and keep warm for 70 minutes; turn the left transmission shaft (11), left transmission shaft (27), right transmission shaft (23), right transmission shaft (19) Put the intermediate shaft (20) into a freezer with a temperature of -50°C and freeze for 70 minutes.
[0018] The second step is to install the transmission shaft. Use heat-insulating gloves to go out to heat and cool the treated parts, wipe off the oil on the surface, and quickly assemb...

The invention relates to an assembly method of an elevator outlet conveying device special for shopping trolleys. The assembly method aims at overcoming shortcomings in an existing assembly method andreducing assembly losses. Assembly steps include that firstly, interference fit parts are heated and cooled; secondly, conveying shaft part assembling is carried out, the heated and cooled parts aretaken through a heat isolation glove, engine oil on the surfaces is thoroughly removed, and quick assembling is achieved; thirdly, a conveying shaft component and a rack are fixedly connected; fourthly, a motor and a coupling are installed; fifthly, a limiting mechanism is installed; and sixthly, a tensioning mechanism is installed. Through assembling through the method, the assembly quality and the assembly accuracy can be guaranteed.
