Description
[technical field]
The present invention relates to a kind of seamless butt-joint rail junction plate, it belongs to railway construction material field, particularly rail connecting parts.
[background technology]
The rail connected mode of present use, a kind of is that common microscler plate body connects, and the shrinkage joint in cross section is arranged between the rail.In train running, will cause not plateau like this.Another connected mode is that rail is directly welded, and such structure is difficult to solve the problem of expanding with heat and contract with cold of rail again.And the cost of such welding connecting mode is very expensive.Only be only applicable to high-speed railway at present, but the part need connect still with common plate.The third, the termination shape of change rail connects with common junction plate, makes the shrinkage joint misplace, such as oblique contract type termination or concave-convex type termination.Though such structure can solve the problem at shrinkage joint, need carry out deformation processing to rail, difficulty of processing is big, processing cost height, and rail end easy deformation.
[summary of the invention]
The object of the present invention is to provide a kind of have simple in structure, no consumable accessory, the convenient and level and smooth seamless butt-joint rail junction plate of connection.
The object of the present invention is achieved like this:
A kind of seamless butt-joint rail junction plate, it comprises microscler plate body, described microscler plate body is provided with and is used for and the fixing hole of rail, it is characterized in that described microscler plate body is provided with the half of protruding rail of protrusion, and the thickness of described half of protruding rail is 1/2nd of rail track face width degree; The center of the half of protruding rail on the described microscler plate body is arranged on the position of the shrinkage joint length in length center that departs from microscler plate body.
The length of described half of protruding rail equals or near the width of rail rail level.
The described hole that is arranged on the microscler plate body has two kinds, is the line of demarcation with half of protruding rail, Yi Bian be fixing hole, another side is a telescopic hole.
Described fixing hole is a circular hole; Described telescopic hole is a slotted hole.
The center of the half of protruding rail on the described microscler plate body is arranged on the position of the shrinkage joint length in length center that departs from microscler plate body, and described shrinkage joint length is 0.5～2.0 centimetre.
The present invention is simple in structure, and no consumable accessory is safe and reliable, does not need to change the ends of rail shape during installation, and particularly the transformation of shrinkage joint, original band cross section railway being changed does not need mobile rail, only need be to the certain rail length of each ends of rail excision; Seamless rail joint is practical connect in cost minimum, can satisfy the performance requirement that rail expands with heat and contract with cold, can guarantee that again various rail vehicle high-speed smooth travel.

[specific embodiment]
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are further detailed the present invention:
In the present embodiment, it comprises microscler plate body the present invention, described microscler plate body is provided with and is used for and the fixing hole of rail, described microscler plate body is provided with the half of protruding rail of protrusion, the thickness of described half of protruding rail is 1/2nd of rail track face width degree, and the thickness of half of protruding rail is just in time identical with the thickness of rail after connecting realization.In order to make connection can satisfy the requirement of expanding with heat and contract with cold, the center of the half of protruding rail on the described microscler plate body is arranged on the position of the shrinkage joint length in length center that departs from microscler plate body.In order to realize the connection of rail, at described microscler plate body body, described microscler plate body is provided with and is used for and the fixing hole of rail.The described hole that is arranged on the microscler plate body has two kinds, is the line of demarcation with half of protruding rail, Yi Bian be fixing hole, another side is a telescopic hole.For the purpose that connects and regulate, the telescopic hole on the corresponding other block length shape plate body of the fixing hole on the one block length shape plate body.Described in the present embodiment fixing hole is a circular hole; Described telescopic hole is a slotted hole.The center of the half of protruding rail on the described microscler plate body is arranged on the position of the shrinkage joint length in length center that departs from microscler plate body, and described shrinkage joint length is 0.5～2.0 centimetre.
Below just connected mode of the present invention and operating principle are further detailed.
As Fig. 3, shown in Fig. 4, Fig. 5 and Fig. 6:
Rail is pressed the fore-and-aft direction setting.The leading portion of the microscler plate body 1 in the left side and the contact surface of rail are made coarse planar shaped contact surface to increase fixed friction power between the two, its fixing hole 5 and connecting screw rod 4 are made equal diameters with the rail connecting hole, make the leading portion of the microscler plate body 1 in the left side and front rail 3 connect into the immovable integral body of the relative position when rail expands with heat and contract with cold.The half of protruding rail supporting thickness that is connected as a single entity with microscler plate body is far longer than former rail supporting thickness, and so half of rail can reach the bearing capacity of whole rail fully.The front end of the half of protruding rail 2 of the microscler plate body 1 in the left side and the termination closed butt joint of front rail 3, this butt joint completely polishes with the electric welding weldering in the rail cover position of crossing wheel, forms the smooth rail cover of slitless connection.The back segment of the microscler plate body 1 in the left side is made smooth some face shape with the contact surface of rail and is contacted, to reduce the frictional force when rail expands with heat and contract with cold displacement between the two, and be connected with the back rail with standing screw 4 by telescopic hole 6, leave the shrinkage joint between the rear end of the half of protruding rail 2 of the microscler plate body 1 in the left side and back rail 3 terminations, make that the relative position when rail expands with heat and contract with cold can free displacement between the back segment of the microscler plate body 1 in the left side and the back rail 3.The microscler plate body body in the right in like manner connects, the dislocation combination of left and right like this one side one block length shape plate body, and the mistake bridge-type that forms one section slitless connection is carried rail.
Operating principle of the present invention is as follows:
When train the past, backward directions were travelled, wheel drives on the half of protruding rail on the left side of slitless connection from the front rail earlier, on the shrinkage joint between the front end of the half of protruding rail on the right of driving to simultaneously and the termination of front rail, then drive to a left side, on the mistake bridge-type protruding rail that right junction plate lumps together, then exercise on the half of protruding rail on the right, drive to simultaneously on the shrinkage joint between the termination of the rear end of half of protruding rail on the left side and back rail, then the half of protruding rail from the right drives on the back rail of slitless connection, has so far finished once and has walked the transition of the same rail joint stably of normal rail track face and travel.
