Description

A three-dimensional garage

technical field

The present invention is a three-dimensional garage.

Background technique

The conventional three-dimensional parking garage and car wash area are set independently, which increases the occupied area of the site. How to realize the cleaning of the vehicle in the process of vehicle handling (driving the vehicle to lift, translate, stop, etc.), save time, Land has become an urgent problem for the company's researchers.

In addition, the parking method of the traditional three-dimensional garage is to drive into the lift area by yourself or park the vehicle in the transfer area, work through the car pick-up mechanism, drag the vehicle into the lift area, and finally store the vehicle;

However, in the process of saving the car, you will face the following problems:

1. Since the conventional car pick-up mechanism can move in a straight line or in a curve, when the vehicle is parked in a slanted transfer area or in a lift area, the car pick-up mechanism with linear motion cannot accurately locate and pick up the vehicle, while the curved pick-up mechanism can. It is necessary to accurately locate the vehicle first, and then pick up the vehicle, which takes a long time to pick up the vehicle and is inefficient;

The surface of the vehicle is attached, and the lifting frame drives the brush to descend or ascend to realize vehicle cleaning.

It should be noted here that when the vehicle is put into storage, the lifting frame is located at the top to prevent it from interfering with the storage of the vehicle; the basic information of the vehicle (such as length, width, height, wheelbase, weight, etc.) The license plate scanner will know.

How to realize the lifting movement of the lifting frame, the present invention adopts the lifting frame to be connected with the vertically arranged screw rod through the screw nut; the motor drives the plurality of screw rods to rotate synchronously through the connection between the synchronous shaft and the steering gear.
