Description

Technical Field

[0001] The utility model relates to a wheel lifting mechanism used for vehicle detection. Background Art

[0002] The car wheel on the double-roller inspection platform is between the two rollers, and it is difficult for the wheel to climb out of the rollers. The inspection platform is equipped with a lifting mechanism to lift the car wheel to drive the car away. When the car drives away, the wheel instantly rotates and accelerates on the lifting mechanism, causing the airbag jack in the lifting mechanism to be instantly twisted or deflected by the force. After repeated many times, it is very easy to damage the rollers and electronic components on the inspection platform, resulting in inaccurate vehicle inspection results. Utility Model Content

[0003] The purpose of the utility model is to provide a wheel lifting mechanism for vehicle inspection, which is used to solve the problem that the airbag jack in the lifting mechanism is twisted or deflected by instantaneous force, which easily damages the roller and electronic components on the inspection table.

[0005] A wheel lifting mechanism for vehicle inspection includes a base plate and a top beam, with multiple airbag jacks arranged between the base plate and the top beam, channel steels fixedly connected at both ends of the base plate, first inclined blocks fixedly connected to both sides of the upper end of the channel steel, a trapezoidal limiting groove is formed at the upper end of the channel steel by two first inclined blocks, a limiting block corresponding to the shape of the limiting groove is arranged in the limiting groove, support seats are fixedly connected at both ends of the top beam, and the limiting blocks are fixedly connected to the support seats.

[0006] The limiting block comprises a hard rubber block, a plurality of threaded pipe sleeves are welded in the hard rubber block, and the threaded pipe sleeves are fixedly connected to the support seat through bolts.

[0007] A plurality of cylinders are arranged between the bottom plate and the top beam, and two ends of the cylinders are connected to the bottom plate and the top beam respectively.

[0008] A top plate is fixedly connected to the top beam, and a plurality of anti-skid ridges are welded on the top plate.

[0009] The bottom surface of the limiting block facing the channel steel is an inclined surface, and a second inclined block corresponding to the shape of the bottom surface of the channel steel is fixedly connected to the bottom surface of the upper end of the channel steel.

[0010] The beneficial effects of the present invention are as follows: when the top beam lifts the wheel, the limit blocks at both ends of the top beam are stuck in the limit grooves to limit the top beam and prevent the top beam from moving, so that the gear cannot transmit the lateral force to the airbag jack, thereby avoiding the distortion or deflection of the airbag jack, preventing the rollers and electronic components on the inspection table from being damaged, and ensuring the accuracy of vehicle inspection.
