In vehicle impact test, traction track and extension pulley are important rigs for testing.During the central collision test, after extension pulley motoring ring test vehicle reaches certain preset vehicle speed, the extension pulley cut is also thrown off with instruction carriage, and instruction carriage hits impact walls with free velocity.In this sight, the stop position of extension pulley and impact walls position are all fixed.Yet, in the tests such as vehicle offset collision, side impact, car and car crash, but very flexible to the requirement of draw and release point position.But, due to diversity and the extendability of test form, can't all design fixing draw and release point and coaster draw-gear for each forms of collision.
Summary of the invention
Purpose of the present invention is exactly the defect for prior art, and a kind of Rail sliding car stop device is provided.This device can be arranged on the optional position of traction track, relies on the friction force effect to force extension pulley to stop, and Reusability does not damage track.The application of the invention, extension pulley can stop in the traction track optional position, thereby meets the demand that automobile central collision, side impact, offset collision, car and car crash in test and be connected with instruction carriage power at desired location disconnection extension pulley.
The technical solution used in the present invention is: a kind of Rail sliding car stop device, comprise the clamping device for clamping with traction track, described clamping device end is provided with the buffer stopper that protrudes from clamping device, described clamping device is provided with clamping structure, on described clamping device, for the binding face clamped with traction track, is provided with friction disc.The huge energy that buffer block structure can produce impact moment evenly conduct to stop device, and stop device produces flexural deformation can prevent from colliding the time; Thereby reach the purpose of regulating friction force size by the size of adjustable clamp locking structure adjusting clamping force; Rubber friction disc is connected and directly contacts with traction track with stop device, can provide braking required friction force.
Further preferred structure, described clamping device comprises that main shaft, center hinge are connected on two groups of cross one another swivel arms on main shaft and the grip block for fixing to clamp with traction track be connected with the swivel arm end.
Further preferred structure, described grip block is provided with reinforcement.
Further preferred structure, described buffer stopper is arranged on the grip block end, and described buffer stopper protrudes from grip block.
Further preferred structure, described buffer stopper comprises and the rectangular block of extension pulley head-on collision and the wedge for the collision energy conduction be connected with rectangular block.
Further preferred structure, described clamping structure is arranged on grip block.
Further preferred structure, described clamping structure is adjustable bolt.
Further preferred structure, described friction disc comprises and being arranged on grip block for the relative upper friction plate on the binding face fixed to clamp with traction track and lower friction disc.
The present invention is simple in structure, volume is small and exquisite, flexible for installation, can be clamped in the optional position of vehicle impact testing traction track, clamping force is adjustable, does not damage track.The friction force produced by friction disc and interorbital makes the Rail sliding car effective brake, can realize coaster braking and the draw and release of automobile optional position in central collision, side impact, the test that crashes, for impact test brings great convenience.Solved the problem of extension pulley and instruction carriage unhook position changeable in the tests such as automobile side crash, offset collision, car-car crash, thereby greatly improved the utilization factor of traction track, avoid the high removable impact walls of use cost, greatly reduced the Lab Establishment cost.
