The U-shaped protective pad is a rubber pad.

And a groove used for being clamped with the side wall of the bearing plate is arranged on the outer side wall of the U-shaped protection gasket.

The mounting box comprises a box body and a box cover, wherein an opening is formed in one side wall of the box body, which faces the weighing main body, so that a probe of the laser wheel axle recognizer can be avoided.

The fixing structure comprises a bolt hole arranged on the bottom wall of the box body, and a bolt hole used for punching is connected with a bolt hole in the laser wheel shaft recognizer to fix the laser wheel shaft recognizer.

And foam layers are arranged on the inner side walls of the box bodies.

And each transition belt is provided with an anti-skid structure.

The antiskid structure comprises strip-shaped antiskid projections which are horizontally arranged at intervals and have the length extending along the direction vertical to the running direction of the vehicle.

The utility model has the beneficial effects that: according to the utility model, the bearing plate of the weighing main body is directly clamped on the transverse rod part of the L-shaped mounting rod below the bearing plate, and is protected by the U-shaped protective liner, so that the clamping groove and the transverse rod part are prevented from being in hard contact and touching. And the laser wheel axle recognizer is fixedly arranged in the mounting box by a fixing structure, and the laser wheel axle recognizer on the mounting box performs laser scanning recognition on the wheel axle information of the passing vehicle. Abandon the bolted connection among the prior art, avoided long-term vehicle to strike to cause the shaft recognizer to rock and lead to leaking the problem of axle, heavy-duty axle.
