Description

Technical Field

[0002] This invention is a divisional application, the original application number is: 202110131827.6, the invention name is: A shuttle gear transmission external clamp transporter and use method, the original application date is: 2021.01.30;

[0003] As the number of motor vehicles continues to increase and the number of parking spaces in cities is limited, in order to build more parking spaces per unit area, smart multi-story parking garages have emerged, and mechanical assisted parking equipment plays a vital role.

[0004] There are two main types of car transporters on the market: 1. Using small diameter (<100mm) rubber wheels, the transporter moves under the car, clamps the four tires of the car through the clamping rod, and lifts the car to the destination. This type of transporter has several disadvantages: the rubber wheel has a small diameter, the linear speed is lower at the same speed, and the efficiency is low; the smaller diameter wheel has a smaller contact area with the ground, and the friction is smaller, which is also not conducive to walking; when storing and retrieving the car, there will be a certain gap between the moving car and the bottom plate of the parking space, and the small wheels will cause impact, which greatly reduces the service life of the transporter. 2. Using the friction between the plate chain and the car wheel to transport the car to the parking space, this solution requires the installation of a plate chain mechanism in all parking spaces, which is costly, and the plate chain mechanism is complex, easy to damage and difficult to maintain.
