Abstract
The invention discloses a device for testing the transverse impact of a railroad switch, belonging to the field of railroad component detection technology. The device consists of a mounting bottom plate provided with a mounting hole and a stock rail mounting component, a rigid shaft support rack and a sensor support rack both fixedly connected to the mounting bottom plate, a rigid shaft mounted on the rigid shaft support rack via a linear sliding bearing structure, a force testing sensor mounted on the sensor support rack and a displacement sensor mounted on the rigid shaft support rack near a switch guard rail, wherein one end of the rigid shaft is connected with the force testing sensor while the other end thereof is fixedly connected a guard rail connecting block for the connection with the switch guard rail. The device has the advantages of being simple in structure, easy in manufacturing and mature and reliable in technology. The device can rapidly and accurately test the transverse impact force of train wheels on the switch guard rail and the transverse displacement value of the guard rail on the spot when the train passes through the switch.
Description
Technical field
The present invention relates to a kind of multi-point sampler device that is applied to railway switch guard rails lateral impact forces and displacement measurement.Genus railway Components field.
Background technology
At present the trend of passenger vehicle high speed, shipping heavy loading has been aggravated the dynamic interaction between train and track switch greatly, when train is crossed trouble horizontal ride comfort requirement higher, must grasp the side knock effect of track switch each several part and avoid weakening the track switch lateral stability.Yet in switch structure, the transverse force that railway switch district, railway frog district etc. locates and displacement are difficult to adopt the traditional test technology to record, generally adopt computer simulation to calculate (referring to " railway construction journal " the 3rd phase of calendar year 2001 " SIMULATION OF LATERAL IMPACT VIBRATION OF GUARD RAIL ") both at home and abroad, but realistic model can not tally with the actual situation fully through simplifying calculated results.
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, provide a kind of train wheel that can accurately test out at the scene to the device for testing transverse impact of railroad switch of the value of lateral displacement of the lateral impact forces of turnout guard rail and turnout guard rail.
The device for testing transverse impact of railroad switch of realizing the object of the invention by the mounting base that is provided with mounting hole and stock rail installation component, be fixed in stiff shaft bracing frame on mounting base and sensor support frame, be arranged on stiff shaft on the stiff shaft bracing frame, be arranged on the force cell on sensor support frame and be arranged near the displacement transducer on the stiff shaft bracing frame of turnout guard rail and consisted of by the linear slide bearing arrangement, one end of described stiff shaft is connected with force cell, and the other end is connected with the guard rail contiguous block that a confession is connected with turnout guard rail.
Utilize the mounting hole on mounting base that this proving installation is arranged on sleeper during use, the stock rail of track switch is arranged in the stock rail installation component of mounting base, and turnout guard rail is arranged on the guard rail contiguous block, and guarantees that stiff shaft is perpendicular to the guard rail installed surface.Train wheel by the time act on turnout guard rail lateral impact forces pass to stiff shaft by the guard rail contiguous block of turnout guard rail through being connected with turnout guard rail and then pass to force cell and predicted; The shift value of turnout guard rail is by the displacement transducer perception.Thereby completing train wheel accurately tests the lateral impact forces of track switch and the on-the-spot of value of lateral displacement of turnout guard rail.
Advantage of the present invention is simple in structure, and it is convenient to use, and technology maturation is leaned on.Can test out rapidly and accurately at the scene train and cross when trouble train wheel to the lateral impact forces of turnout guard rail and the value of lateral displacement of guard rail.
The present invention is further described below in conjunction with drawings and Examples.
