Clamp arm pickup device

Abstract

The invention provides a clamp arm pickup device, which comprises a travelling device, a clamping device and an adjusting device. When a car is picked up, a front wheel base plate and a rear wheel base plate are driven to move through a travelling motor in the travelling device, and the position of the rear wheel base plate can be adjusted through the adjusting device according to different lengths of car bodies. When the clamp arm center of a rear clamp arm mechanism in the clamping device deviates from rear wheels, the two clamp arms for clamping the same tire are not contacted with the tire at the same time in the closing process of clamp arms, one clamp arm contacted with the tire at first receives the opposite acting force of the tire, the rear wheel base plate is pushed to move in the opposite direction under the action of the opposite acting force, a screw rod on the rear wheel base plate drives a touch rod to overcome the acting force of a spring and touch a corresponding micro-switch, and a PLC (programmable logic controller) control system is used for controlling the motor to drive the screw rod to rotate according to a received signal until the clamp arm center is aligned to the rear wheel center. The clamp arm pickup device is simple in structure and high in automation level, and can achieve the accurate positioning function.

Description

technical field [0001] The invention relates to a car access device for a three-dimensional garage, in particular to a clamp arm car retrieval device. Background technique [0002] At present, when accessing a car in a three-dimensional garage, photoelectric switches are often used to detect the position of the tires. Because the tires are not reflective enough and the hubs are porous, detection errors are often caused, resulting in inaccurate positioning of the center of the clamp arm and the center of the rear wheel. In addition, most of the clamping arms used for vehicle clamping are driven by chains, and the nuts and lead screws are lifted. The transmission efficiency is low, the operation noise is large, the structure is cumbersome, and the failure rate is high. These are the shortcomings of the existing technology. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clamping arm picking-up device that can rea...

[0002] At present, when accessing cars in the three-dimensional garage, photoelectric switches are often used to detect the position of the tires. Because the tires are not reflective and the hubs are porous, detection errors are often caused, and the positioning of the center of the clamp arm and the center of the rear wheel is not accurate.

In addition, the clamp arms used for vehicle clamping are mostly driven by chains, and the nuts and lead screws are lifted. The transmission efficiency is low, the operation noise is large, the structure is cumbersome, and the failure rate is high. These are the shortcomings of the existing technology.
