Lifting device of vehicle detecting system

Abstract

The invention discloses a lifting device of a vehicle detection system. It has a bearing platform, on which there are active push-pull frame, fluid pressure push-pull device, thrust rotation support, rollers are arranged under the active push-pull frame, and rotation support is arranged above, between the rotation support and thrust rotation support There is a driven lifting frame on the top, and a load cell is installed under the load-bearing platform. The load cell is fixed on the frame. The driven lift frame has a load-bearing table, an inclined plane, and an up-and-down motion guide. The up-and-down motion guide includes a guide surface and guide rollers. And the guide groove, the guide groove is fixed on the frame, and the bearing platform itself is composed of the bearing platform bottom plate and the horizontal guide device of the active thrust frame. The present invention has the advantages of: 1) improving the stress on the air cylinder or oil cylinder, the air cylinder or oil cylinder only has pulling pressure, and no lateral bending force is required, which improves the working life and reliability of the air cylinder or oil cylinder; 2) the overall height is small, the structure is compact, It is convenient for the overall layout of the system; 3) Uniform force and stable lifting; 4) Easy maintenance.

Description

technical field [0001] The invention relates to a lifting device of a vehicle inspection system, which is mainly used for lifting vehicles between rollers in a roller-type motor vehicle inspection system, and aims to ensure that the vehicle can enter and exit the inspection platform conveniently. Background technique [0002] At present, the vehicle lifting device between the rollers in the roller-type motor vehicle detection system generally adopts air cylinders (airbags) or oil cylinders to directly lift up and down. When the vehicle enters between the rollers, the system controls the air cylinder (airbag) or oil cylinder to move up and down directly, so as to realize the lifting of the vehicle. The air cylinder (airbag) or oil cylinder of this device is generally installed vertically, which requires an increase in the overall height of the equipment. Generally, the upper surface of the equipment is on the same level as the ground. Since the cylinder (oil cylinder) is gene...

AI Technical Summary

Problems solved by technology

When the vehicle enters between the rollers, the system controls the air cylinder (airbag) or oil cylinder to move up and down directly, so as to realize the lifting of the vehicle. The air cylinder (airbag) or oil cylinder of this device is generally installed vertically, which requires an increase in the overall height of the equipment. Generally, the upper surface of the equipment is on the same level as the ground. Since the cylinder (oil cylinder) is generally installed vertically, the distance between the equipment and the ground is relatively large. In addition, due to the bending moment caused by the deviation of the parking position of the vehicle from the center of the cylinder (airbag) or oil cylinder, the cylinder (airbag) or oil cylinder is more prone to failure.
