Base top sets gradually force sensor, top board and experiment voussoir, and the upper surface of the top board is provided with bar
Shape groove, force snesor is connected by data wire with control terminal end described in the bar-shaped trough interior installation experiment voussoir.
Further, the base is rectangular block architecture, and one is respectively equipped with four angles of the rectangular block architecture
Tapped through hole, a ground bolt is threaded with each tapped through hole.
Further, the base upper surface is arranged with two rows centered on rail axial direction, often arranges two grooves, often
A force snesor is provided with individual groove, the top board contacts surface with force snesor and is provided with to match with sensor contact
The matrix round platform of conjunction.
Further, the base and top board are equipped with reinforcement and rib.
Further, the both ends of the experiment voussoir are respectively equipped with nylon block.
Further, the beneficial effects of the invention are as follows：
The present invention is reasonable in design, is easily installed, dismantles, reusable, suitable for all kinds of rail traffic vehicles wheels
Weight off-load experiment, both avoided reconstruct adapt to the vehicle weighing unit position caused by time cycle and financial resources on wave
Take, turn avoid the financial cost burden caused by buying professional equipment, while the frock is implemented in actual items, its safety
Property, feasibility are all sufficiently verified.
