Description
Technical field
The present invention relates to the rail joint clamping device adopted when having hurt to safeguard in the middle part of the emergent installation and rail of railway track joint.
Background technology
In this area, the device of the connection realizing two adjacent one steel rails is in orbit called rail joint.
The mode that the connection of domestic and international conventional railway rail connects based on splice bar, the structure of rail joint comprises the splice bar being arranged on rail both sides, splice bar is fixed with rail by bolt and spring washer circle etc., and between rail, specially leave the requirement of expanding with heat and contract with cold to meet rail in gap.Under this connected mode is also usually applied to the cases of emergency such as the fracture of conventional track, making also can Interim use before broken rail has little time maintenance.The shortcoming of this connected mode needs to hole on rail, wastes time and energy, have impact on operating efficiency when carrying out at the scene.
In order to avoid holing on rail, a kind of rail joint clamping device that is used for is suggested, as shown in Figure 1, it comprises the splice bar 102 be clipped on rail 101 both sides, for clamping chuck 103, the bolt 104 passed below rail 101 of splice bar 102 and being combined with bolt 104, for tightening up the nut 105 of described chuck 103.
But, due to downward moment can be produced at the two ends of bolt 104 when gripping means grips, therefore, bolt 104 can be made after Long-Time Service to bend deformation, cannot recycle.
In addition, ballastless bed for rail track, due to the pitch-limited system between rail and railway roadbed, some minimum spacings only have 25mm, if bolt will be made to pass below rail, then the diameter of bolt must be less than 25mm, otherwise the nut at two ends cannot be tightened.But such bolt cannot meet the requirement in intensity, namely due to above-mentioned moment, bolt is caused to be out of shape or fracture.
In addition, splice bar is provided with hole 106 by prescribed distance.But due to the impact of track condition or obstruction, the density of setting of this some holes 106, be often not enough to meet the requirement of installing, but splice bar is manufactured by Railway Bureau's Uniting, cannot modify, therefore cause the inconvenience of installing to its structure.
Summary of the invention
The object of the invention is to provide a kind of rail joint clamping device, which overcome the problem of the installation inconvenience of installation question and the splice bar caused due to the spacing between rail and railway roadbed in prior art.
Rail joint clamping device of the present invention comprises: the splice bar being clipped in rail both sides; By the chuck that described splice bar clamps to rail; And exert a force to described chuck with the forcing unit making it clamp angularly with horizontal plane.

.
In sum, ensure an intermediate cylindrical parts tension stress of lintel, lower bolt produces the angle theta 3 of power F and level by the cylinder at back rest two ends between θ 1 and θ 2 jiaos to lintel.Figure 18 illustrates the situation of this θ 3, i.e. θ 1< θ 3< θ 2.As seen from the figure, now, x2<x3<x1.
Lower bolt to be produced lintel by the cylinder at back rest two ends and level is the power F of θ 3 jiaos, is decomposed into horizontal component Fx and vertical stress component.At the bottom of Rail, vertical force Fy3 is produced to lintel.Because the quality of lintel itself is very little, suffered gravity is very little compared with F, omits and disregards.
Equilibrium equation is as follows:
Fx=Fx……①
Fy+Fy=Fy3……②
Fx*y+Fx*y=Fy*x3……③
Fx=F*cosθ3……④
Fy=F*sinθ3……⑤
Arrange above-mentioned equation to be easy to get: θ 3=arctan
Present embodiment, in get θ 3=7 °.But in practical operation, can according to circumstances set the value be more suitable for.
