Abstract

The utility model provides a transition type rail connection plate which is suitable for the joint connection of a train rail. The utility model aims at solving and eliminating the problem of noise generated when train wheels impact against rail sections, and provides advantages for speed increasing of a train. The utility model has the technical scheme that a connection plate on the outer side of each rail joint is widened, thickened and heightened, and simultaneously, the lower part of each connection plate forms a flat shape and contacts a platform on the lower part of the outer side of a rail; when train wheels run on the upper surfaces of the connection plates, as both ends of each connection plate are slightly lower than the upper plane of a rail, an effect of train wheel guiding can be performed; when train wheels run to joints of a rail, as the peak of each connection plate, which is corresponding to the connection seam of the rail, is higher than or equal to the upper plane of the rail, the train wheels pass across the upper plane of each connection plate but not directly contact each rail joint in an impacting mode. The utility model provides conditions for noise reduction, transport quality improvement, rail shaking force reduction, etc.

Description

The transition type track connecting plate

Technical field

The utility model relates to a kind of track for a train junction plate, to call the transition type track connecting plate in the following text.

Background technology

The history of train is for a long time far away, the history of track for a train and effect are known by common people especially, how long people is sitting in the train, just have kaka sound how long to be accompanied by this people can be heard without end always, this sound one joint joint track for a train joint sends when clashing into mutually with train wheel, such sound has not only produced bad influence to environment, simultaneously to track, all be pernicious to roadbed, to the passenger, to sleeper, to train.Because the original junction plate of every joint track, can only play the effect of connection, add connection and can not play a part to support, when so in case train wheel is pressed onto tie point, under the effect of train weight, at first first track section header under the wheel has been pressed, at this moment just very natural generation with the difference of height of opposite one joint track head, in the time of above train wheel drives to the wheel road, opposite that is higher than the wheel bottom, it must be elder generation's bump with transition type, the state that rolls in the back travels, one successively, in 1 year year of rows of trains, what go round and begin again is exactly to circulate under the state like this, travelling, though people very tired this clickly, clickly sound, but because the historical custom sound that transmits, just as likelihood manage by eternal the accepting of people.Now to when should address this problem.

The purpose of this utility model is to provide a transition type track connecting plate, to eliminate the impact sound that produces with every joint track in the train vibration influence, with change the impact that produces because the track joint is arranged, for the running quality of improving train and the raising of the speed of service create conditions.Simultaneously to the use of track, to roadbed, to sleeper, to the passenger, all provide condition to the raising of vehicle-mounted freight transportation quality or the like aspect.Particularly also created condition to the minimizing of train way noise along the line with near the train way reduction of shaking force along the line.

Summary of the invention

This utility model is achieved through the following technical solutions.Under the situation that need not change the track for a train shape, only change the vibrations that the junction plate that connects track just can be realized abating the noise and clash into generation.Be exactly the joint of per two tracks junction plate in the outer part under the situation of lengthening, increase slightly a bit again, make that to be camber line shape in the middle of the junction plate a little higher than or equal the height at two rail joint places.Two is lower than plane on the track again slightly, to cut into track bottom certain depth to the bottom of junction plate simultaneously, such junction plate can play the effect that connects track, can play simultaneously the effect of carrying train weight again, because each two above such junction plate all will be lower than 1-3 millimeter in plane on the track slightly, when carrying out the transition to track connector place, junction plate is greater than or equal to the last plane of track again slightly.So no matter train is to which direction running, the joint that train wheel drives to each track all is that transition type rolls in the past on such junction plate.And can not produce clickly clickly impact sound fully.Be sitting in above the track outer lower portion plane because the lower plane of each junction plate is flat, so just can not produce junction plate under the weight compressing of train and the sagging state that produces.Because such junction plate is the outer then face that is assemblied in track, so also can not produce any variation of gauge.Better for the transiting performance that makes junction plate, the length of the junction plate that suitably extend, with increase train wheel by the time stationary performance.Also want suitable thickness to thicken simultaneously, to increase the operating period and the supporting capacity of junction plate junction plate.

Advantage of the present utility model is that such junction plate can play the double action that connects track, carrying train weight simultaneously.Be sitting on the plane body at two joint rail joint places because the lower plane of such junction plate is flat,, also can not make the joint of track produce difference of height so be that the weight of train was all pressed from the joint of track.Because two of junction plate is lower than the last plane of track slightly, thus train no matter from which direction running to the joint, can not produce the phenomenon that the joint generation of wheel and road is clashed into.Track by such transformation has that noise is low, the speed of a motor vehicle fast, does not have bump, vibrations are light, reduced investment, transformation are easy to advantage.Particularly can need not change track, change and using such junction plate under the defeated state of not stopping transport.

Description of drawings

Be in conjunction with the accompanying drawings the utility model to be done a progressive explanation below.

Fig. 1 is that schematic diagram is installed and used to junction plate in track side surfaces.

Fig. 2 is along the A-A sectional view among Fig. 1.

Fig. 3 installs and fixes schematic diagram for the junction plate symmetry is installed in track both sides and track and sleeper.

Among the figure 1, track 2, bolt hole 3, baseplane 4, arcwall face 5, butt joint 6, junction plate 7, original junction plate 8, railway spike 9, sleeper 10, inclined plane.

The specific embodiment

From Fig. 1, Fig. 2 as can be known, said junction plate (6) is to copy the shape of track (1) side to make near the facade of track (1), match with vertical baseplane (3) of track (1) outer lower portion in the baseplane of said junction plate (6), the inclined plane (10) at junction plate (6) two will be lower than the last plane 3-0 millimeter of track (1) in the length of 50-100 millimeter, the arcwall face (4) on the last plane of junction plate (6) respective carter butt joint (5) will be greater than or equal to the last plane of track (1) on the length of 200-500 millimeter, at least can not be lower than the last plane of track (1), the original junction plate of inboard face utilization (7) of said track (1) is connected with bolt with opposite junction plate (6).The inclined plane (10) at junction plate (6) two, owing to be lower than the last plane of track (1), so when train wheel drive to the corresponding two orbital dockings seams (5) of junction plate (6) above the time, under the effect of the arcwall face (4) on junction plate (6), wheel does not directly bump against with rail joint, but above junction plate (6) transition type fall back to track (1) above travel.Because under the double action of the extradition of junction plate (6) and transition, make train wheel fully the chance of clashing into mutually with the track section header can not be arranged, institute thinks that the low noise of realization train is provided by the condition that provides.

Track is installed in sleeper (9) under the stationary state of railway spike (8) as can be seen from Figure 3, junction plate (6) and the schematic diagram of two tracks (1) when symmetry is installed and used.

Since said junction plate (6) at thickness, highly, shape all is very different with the junction plate (7) of original use, particularly since thickness from far away greater than the thickness of original junction plate (7), so can not be installed in the side, the inside of track (1) to junction plate (6), if junction plate (6) is installed in the inboard of track (1), track space between track (1) and the track (1) will narrow down, even has an accident.If junction plate (6) is assemblied in the outside of track (1) according to the form of Fig. 3, then have many good qualities, can not influence the gauge of track (1).Junction plate (6) baseplane is seated in above the plane body (1) in track (1) outside of being processed into the plane.So when can make train wheel be pressed in arcwall face (4) above the junction plate (6), junction plate (6) and the two rail joint portions that are connected are almost bearing the total weight of train simultaneously, have avoided the difference of height of track (1) joint generation fully.So also just eliminated the impact noise that produces between train wheel and the track fully.The thickness of said junction plate (6) can be selected in the 20-80 millimeter.Said junction plate (6) central longitudinal is greater than the length of junction plate (6) to the junction plate bolt hole of arranging (2) and original junction plate (7) central longitudinal to the length of the baseplane (3) of bolt hole (2) bottom of arranging, and will equal the length of junction plate (6) at least.

Because the baseplane (3) of junction plate (6) is to be placed on the track of two track section headers that are processed into the plane, so bolt above the junction plate (6) and bolt hole (2) just can not produce shearing force radially, provide safety assurance with being connected of track (1) for guaranteeing track (1).In junction plate (6) and original junction plate (7) grip track (1) two, guarantee to stay the gap between the last plane of the baseplane (3) of junction plate (6) and per two the section header lateral surfaces of track.Said junction plate (6) all is mounted in above the plane (3) of each root track (1) lateral surface connector portions.
