Abstract

The utility model relates to a sleeper beam without vibration for the railways orbital. The sleeper converts the existing plane end-face of track beam to curved end-face in order to form a carrying face of similar continuity. Thereby, the sleeper effectively avoids the wheels coincidence with the interstitial formed of thermal expansion and contraction, eliminates the impact owing to the vehicle at the volley, and reduces vibration and noise. The rail jointer connects with the slide friction of convex-concave track, depends on a couple of effective contact faces to control the transversal slippage. So the sleeper can control the accidents of train aberration in case of the splint fastening bolt out of work and makes the train running steady. The utility model improves the status of rail transport.

Description

Sleeper beam without vibration

The utility model relates to the joint of a kind of Sleeper beam without vibration of railroad track, particularly a kind of beam-and-rail.

Well-known existing beam-and-rail generally adopts plane free type joint, the rail end face is the plane, vertical mutually with ground, this problem owing to expand with heat and contract with cold, make two pinned bonds place exist all the time one with wheel the gap that matches of rail level (load line), when the gap is widened to extreme position, two rail ends being fastenedly connected of clamping plate that place one's entire reliance upon, because the existence in gap, sectional joint, train wheel has produced vibration and noise during through the junction, and each securing member is not only being impacted in the existence of this phenomenon consumingly, and the application life of part in depletion, also increase simultaneously the resistance of vehicle operating, increased energy consumption.

A kind of Sleeper beam without vibration that the objective of the invention is to avoid in the above-mentioned prior art harm owing to formed vibration in existing play movement and noise to provide is for wheel provides an approximately continuous track.

The objective of the invention is to reach: the shape that changes end face at the two ends of beam-and-rail by following measure, adopt the method for " breaking the whole up into parts ", existing beam-and-rail planar end is become bent change face end face, thereby reasonably decompose the bearing surface of beam-and-rail end and the gap of expanding with heat and contract with cold, make wheel rail level and the gap of expanding with heat and contract with cold stagger, form one and be similar to successional bearing surface, the purpose that realizes eliminating vibration and reduce noise.Ensure rail because the existence in temperature difference linear expansion gap, overcome the expand with heat and contract with cold unexpected interruption of the formed beam-and-rail bearing surface in gap of existing beam-and-rail joint, make that train can even running.

Structure of the present utility model is to have changed the method that the simple dependence clamping plate of existing beam-and-rail joint are fastenedly connected, adopt convex-concave rail end at the rail joint two ends, shape is circular arc, forming two pairs of sliding friction surface in the dovetail connector position connects, as shown in Figure 1, therefore clamping plate bolt looseness and the changing of the relative positions of the left and right directions that forms is subjected to strict restriction like this even under the situation of clamping plate bolt failure, also can be controlled and the train that the takes place disturbing accident of exceeding the bounds.

The accompanying drawing drawing is described as follows:

The structure chart of Fig. 1, Sleeper beam without vibration termination, wherein: 1. protruding rail end, 2. recessed rail end, 3. rail.

The utility model has following advantage compared to existing technology: reduce the vehicle operating resistance, improve the speed of a motor vehicle, so that train operation is steady, energy savings has prolonged service life of train part exponentially, can be mass, easily processing, small investment, Social benefit and economic benefit is outstanding, has improved the present situation of railway transportation.

Claims

1, a kind of Sleeper beam without vibration that is used for railroad track, the dovetail connector position that it is characterized in that beam-and-rail are to adopt two pairs of convex-concave rail end sliding frictions to connect.

2, Sleeper beam without vibration according to claim 1 is characterized in that the joint of two pairs of convex-concave rail ends is circular arc.
