Abstract
The utility model relates to a brake pipe fixing and damping device for railway freight-car, which is characterized by comprising an upper elastic cushion block, a lower elastic cushion block and an U-shaped pipe strap, wherein the left side and the right side of the upper elastic cushion block are provided with through-holes which allow the U-shaped pipe strap to pass through, the bottom of the lower elastic cushion block is provided with a groove for clamping the U-shaped pipe strap, and the left side and the right side of the lower elastic cushion block are both provided with through-holes which allow the U-shaped pipe strap to pass through, and the U-shaped pipe strap is matched with a nut to fasten the upper elastic cushion block and the lower elastic cushion block. As the utility model is provided with the elastic cushion blocks on the periphery of a fixing point of brake pipes, the brake pipes are protected from being affected by the high-frequency vibration of cars through the characteristic of vibration absorption of the elastic cushion blocks, and the problems that a contact flange between the brake pipes gets loose, and the weld between the brake pipes and the flange cracks are effectively solved. The utility model can be widely applicable to railway freight-cars.
Description
Technical field
The utility model relates to a kind of shock absorption device, particularly about a kind of railway truck with the fixing shock absorption device of brake pipe.
Background technology
Brake pipe is the major part of railway truck Pneumatic brake systems, is full of pressurized air during work.Brake pipe is to be cooperated by elevator nut and elevator directly to be fixed on the pipe flap seat of railway truck underframe.Owing to influenced by the following deflection deformation etc. after vibrations that railway truck is in operation and car body load, becoming flexible can appear in the butt flange between each brake pipe, the problem that the weld cracking between flange and the brake pipe perhaps occurs, thereby cause the gas leakage in the brake pipe, can not keep normal operation pressure, the whole brake system of lorry just can not be worked normally.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind ofly can solve that butt flange between the brake pipe is loosening, the railway truck of the weld cracking problem between brake pipe and the flange is with the fixing shock absorption device of brake pipe.
For achieving the above object, the utility model is taked following technical scheme: a kind of railway truck is with the fixing shock absorption device of brake pipe, and it is characterized in that: it comprises a top elastic cushion block, a bottom elastic cushion block and a U type pipe clamp; The and arranged on left and right sides of described top elastic cushion block leaves the through hole that U type pipe clamp can pass through; The bottom surface of described bottom elastic cushion block is provided with a groove that supplies U type pipe clamp to snap in, and and arranged on left and right sides leaves the through hole that U type pipe clamp can pass through equally; Described U type pipe clamp is by being fastenedly connected with making top elastic cushion block and bottom elastic cushion block cooperating of nut.
End face that described top cushion is fast and bottom surface are and are that there is the toothed semi-circular cambered surface of an epirelief on plane, centre; Cushion fast end face in bottom is a plane, and the centre is corresponding with the top elastic cushion block to be provided with one to recessed toothed semi-circular cambered surface, bottom surface semicircular in shape cambered surface; Upper and lower elastic cushion block is made by the High molecular material mold pressing.
The bottom of described U type pipe clamp is the square-section, and both sides are round section, and the top is threaded, and is made by steel.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is fast owing to be provided with cushion around the brake pipe attachment point, the fast outside of cushion is fixed together with U type pipe clamp and pipe flap seat, brake pipe and car body underframe are realized flexiblely captiveing joint like this, can not occur bending and deformation with the car body distortion, the characteristics of the fast absorbing vibration of cushion have guaranteed that brake pipe can not be affected because of the high-frequency vibration of vehicle.2, the utility model has been owing to reduced the influence of the vibrations of vehicle to brake pipe, can solve effectively that butt flange between the brake pipe is loosening, the problem of the weld cracking between brake pipe and the flange.3, the utility model assembling is simple and convenient, easily changes the outfit with structure realization at present.The utility model can be widely used in the railway truck.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises a top elastic cushion block 1, a bottom elastic cushion block 2 and a U type pipe clamp 3.
As shown in Figure 2, top of the present utility model elastic cushion block 1 is to be made by the High molecular material mold pressing.Top elastic cushion block 1 end face and bottom surface are and are that there is the toothed semi-circular cambered surface 4 of an epirelief on plane, centre, and and arranged on left and right sides leaves the through hole 5 that U type pipe clamp 3 can pass through.
As shown in Figure 3, bottom of the present utility model elastic cushion block 2 is to be made by the High molecular material mold pressing equally.Elastic cushion block 2 end faces in bottom are a plane, middle and top elastic cushion block 1 are corresponding to be provided with one to recessed toothed semi-circular cambered surface 6, bottom surface semicircular in shape cambered surface, the bottom semicircular cambered surface is provided with a groove 7 that supplies U type pipe clamp 3 to snap in, and and arranged on left and right sides leaves the through hole 8 that U type pipe clamp 3 can pass through equally.
As Fig. 4, shown in Figure 5, U type pipe clamp of the present utility model 3 is made by steel, and U-bottom portion is square-section 9, and both sides are round section 10, and the top is threaded.
As shown in Figure 6, when using, earlier U type pipe clamp 3 is passed the utility model the through hole 8 of bottom elastic cushion block 2, be inserted in brake pipe 12 then, pass the through hole 5 of top elastic cushion block 1 again, at last by with the cooperating its overall fixed on the pipe flap seat 13 on the car body of nut 11.
In the foregoing description, the number of teeth on the semicircle cambered surface 6 in semicircle cambered surface 4 in top and bottom and tooth depth can determine that the tooth top circle diameter equals the diameter of brake pipe 12 according to the fast hardness of cushion and the performance of absorbing vibration.
In the various embodiments described above, can also carry out other improvement to structure of the present utility model, these improvement should not got rid of outside protection domain of the present utility model.
