Abstract
The utility model relates to a tie plate fastening switch sleeper bolt structure of a railway switch, which comprises a bolt which is allocated with a cover plate, a tie plate which is formed by an upper plate, a lower plate and a rubber spacer which is clamped between the upper plate and the lower plate, and a lifting tie plate which is arranged under the tie plate, wherein the rubber spacer is arranged under the cover plate, and a limiting liner bushing is arranged in a tie plate bolt hole which is matched with the bolt. The tie plate fastening switch sleeper bolt structure of a railway switch can control the rubber spacer under a plate to be deformed in a reasonable range through reasonably choosing the length of the limiting liner bushing, which guarantees the axial force of a switch sleeper bolt when the elasticity of an elastic layer under a plate is fully kept, a certain vertical pressure is generated on the tie plate and the ride comfort of a track is improved, effectively improves the force condition of the switch sleeper bolt, and prevents the switch sleeper bolt from loosening.
Description
Technical field
The utility model relates to railway switch, is specifically related to the fastening turnout sleeper bolt structure of a kind of railway turnout base plate.
Background technology
Existing railway turnout base plate turnout sleeper bolt directly is connected with switch tie by rubber cushion under the backing plate plate, the tightening power of bolt directly acts on the plate underlayer, if make elastic layer keep elasticity preferably, just certainly will reduce the axial force of bolt, to the anti-loosing effect generation adverse influence of turnout sleeper bolt.Becoming flexible of turnout sleeper bolt, it is good fit that bolt and service sleeve be can not get, and causes the destruction in advance of turnout sleeper bolt pair.If will guarantee the tightening power of turnout sleeper bolt pair, will destroy the elasticity of elastic layer, influence the track switch integral rigidity.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of when fully guaranteeing the turnout sleeper bolt axial force, guarantees the fastening turnout sleeper bolt structure of backing plate of the elastic performance of elastic layer under the plate.
The technical scheme that realizes above-mentioned purpose is: the fastening turnout sleeper bolt structure of a kind of backing plate, it includes the bolt of configuration cover plate and by upper plate, lower plate and be folded in the backing plate that rubber spacer therebetween forms and be arranged at height adjusting cushion plate below the backing plate, below cover plate, be installed with rubber spacer, matched with bolt and in the backing plate bolt hole, be provided with spacing lining.
The utility model is provided with the rigid liner that cooperates with turnout sleeper bolt in the backing plate bolt hole, and constitutes elastic cover plate by be installed with rubber spacer below cover plate, forms the fastening turnout sleeper bolt structure of backing plate with elastic cover plate and the spacing lining combination of rigidity.By rationally selecting the length of lining for use, but the rubber spacer distortion is in reasonable range under the control panel, the elasticity of elastic layer and backing plate produced certain lateral pressure under abundant holding plate, when improving the ride comfort of track, guarantee the axial force of turnout sleeper bolt, improve the force-bearing situation of turnout sleeper bolt, prevent that turnout sleeper bolt is loosening.
Description of drawings
Accompanying drawing is the fastening turnout sleeper bolt structural representation of this backing plate.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, the fastening turnout sleeper bolt structure of this backing plate include configuration cover plate 1 bolt 2 and by upper plate 3, lower plate 5 be folded in the backing plate that rubber spacer 4 therebetween forms and be arranged at height adjusting cushion plate 6 below the backing plate, be installed with rubber spacer 7 below cover plate 1, matching to place with bolt is provided with spacing lining 8 in the backing plate bolt hole.The upper end of its lining 8 place cover plate 1 below, the lower end of lining place lower plate 5 above.
When the utility model was specifically implemented, rubber spacer 7 was installed with in the soffit of cover plate 1 by sulfuration process; Spacing lining 8 adopts nylon sleeve; Height adjusting cushion plate 6 adopts the elastomeric material moulding.
The utility model be equally applicable to insulate backing plate fastening bolt structure of switch tie.
Claims (1)
1, the fastening turnout sleeper bolt structure of a kind of backing plate, include the bolt (2) of configuration cover plate (1) and by upper plate (3), lower plate (5) and be folded in the backing plate that rubber spacer (4) therebetween forms and be arranged at height adjusting cushion plate (6) below the backing plate, it is characterized in that: be installed with rubber spacer (7) below cover plate (1), matching with bolt (2) is provided with spacing lining (8) in the backing plate bolt hole.
