External correlation test adopts the professional equipment integrating hydraulic lifting and wheel remeasurement, and this equipment operating is easy but equipment price is very high.
Build the weighing unit position adapting to this vehicle too large with the professional survey instrument cost of introduction, will cause very large financial burden to enterprise, therefore above two schemes can not adequacy test demand.
Consider economic factors and enterprise's site test hardware facility, develop that a kind of to be applicable to the test unit of low-floor tramcar product that this enterprise produces very necessary.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of low-floor tramcar bogie wheel unloading test tool, is arranged in common rail, can meets vehicle wheel remeasurement function, can realize again simulation distortion track function.Test tooling structure is reasonable in design, safe, reliable, install, unloading process is easy, result data is true and reliable, greatly saves experimentation cost.
In order to realize above-mentioned technical purpose, concrete technical scheme of the present utility model is:
Low-floor tramcar bogie wheel unloading test tool, comprise base, sensor, top board and test voussoir, wherein, base bottom is provided with bathtub construction, and described bathtub construction is used for coordinating with rail, realizes the location of base with firm;
Base top sets gradually force sensor, top board and test voussoir, and the upper surface of described top board is provided with bar-shaped trough, installs force snesor described in described test voussoir and be connected with control terminal end by data line in described bar-shaped trough.
Further, described base is rectangular block architecture, and four angles of described rectangular block architecture are respectively equipped with a tapped through hole, and be threaded in each tapped through hole a ground bolt.
Further, described base upper surface, centered by rail is axial, is arranged with two rows, and often arrange two grooves, be provided with a described force snesor in each groove, described top board and force snesor surface in contact are provided with the matrix round platform matched with sensor contact.
Further, described base and top board are equipped with reinforcement and rib.
Further, the two ends of described test voussoir are respectively equipped with nylon block.
Further, the beneficial effects of the utility model are:
The utility model reasonable in design, be convenient to install, dismantle, reusable, be applicable to the test of all kinds of rail traffic vehicles wheel unloading, both the waste on the time cycle and financial resources of reconstructing and adapting to the weighing unit position of this vehicle cause had been avoided, turn avoid the financial cost burden that buying professional equipment causes, this frock is implemented in actual items simultaneously, and its security, feasibility are verified all fully.
