Rocker arm type vehicle detection table lifting device

Abstract

The invention discloses a rocker arm type vehicle detection table lifting device. The device comprises a bearing table and a supporting device arranged below the bearing table; the supporting device comprises a cylinder arranged horizontally, a cylinder body and a piston of the cylinder are fixedly connected with one end of a connecting shaft respectively, a cylinder push rod arranged horizontally is respectively arranged at two sides of the other end of each connecting shaft, one end of each cylinder push rod is connected with the corresponding connecting shaft, and the other end of each cylinder push rod is simultaneously hinged with one end of an upper rocker arm and one end of a lower rocker arm; the other end of each upper rocker arm is hinged with the bottom of the bearing table, and the other end of each lower rocker arm is hinged with the ground; and limiting devices for limiting the bearing table to shift to two sides are arranged at two sides of the bearing table. The device can prolong the service life of the air cylinder or the oil cylinder and improve the reliability of the cylinder, and is low in integral height, simple in structure and convenient for installation.

Description

technical field [0001] The invention relates to a lifting device for ensuring the convenience of vehicles entering and exiting a testing platform, in particular to a vehicle lifting device used between rollers in a roller-type motor vehicle testing system. Background technique [0002] At present, the vehicle lifting device between the rollers in the roller-type motor vehicle inspection system generally uses a cylinder or an oil cylinder to directly lift up and down. When the vehicle enters between the rollers, the system controls the cylinder or oil cylinder to move up and down directly, so as to realize the lifting of the vehicle. The cylinder or oil cylinder of this device is generally installed vertically, which requires an increase in the overall height of the equipment. Generally, the lifting device The upper surface is on the same level as the ground. Since the cylinder (oil cylinder) is generally installed vertically, the distance that the lifting device penetrates i...

AI Technical Summary

Problems solved by technology

When the vehicle enters between the rollers, the system controls the cylinder or oil cylinder to move up and down directly, so as to realize the lifting of the vehicle. The cylinder or oil cylinder of this device is generally installed vertically, which requires an increase in the overall height of the equipment. Generally, the lifting device The upper surface is on the same level as the ground. Since the cylinder (oil cylinder) is generally installed vertically, the distance that the lifting device penetrates into the ground is relatively large. Due to the bending moment caused by the deviation of the parking position of the vehicle from the center of the cylinder or oil cylinder, the cylinder or oil cylinder is more likely to fail. At the same time, the lifting device is relatively heavy and deep into the ground, and maintenance is also more troublesome.
