Abstract
The utility model provides a novel have seam bridge type rail, utilizes the bolt to pass the mounting hole of the mutual adapted of bridge type connecting plate, rail joint portion and splice plate, screws up the nut and connects the rail that forms, and the bridge type connecting plate at the rail joint department is installed in the outside at the rail joint department to the bridge type connecting plate at intercommunication expansion joint, and higher authority is equalling with the rail face, when the train wheel passes through the rail expansion joint, just rolls above the bridge type connecting plate, can realize the smooth transition of train, high-speed operation. The device has the characteristics of simple structure, convenient manufacture and installation, long service life, safety, reliability, capability of reducing the pollution of noise to the environment, prolonging the service life of wheels, rails and roadbed facilities and the like.
Description
The utility model belongs to a kind of rail.
Existing railroad track is all formed by the positive butt joint of many sections rail, and the butt joint end face of rail is general vertical with the longitudinal axis of rail.Owing to will consider related factors such as rail expands with heat and contract with cold, the both ends of the surface of track bond must leave certain clearance, i.e. shrinkage joint.So, when train travels on rail, cross over the shrinkage joint moment of rail when wheel, because of instantaneous unsettled falling, send between wheel and the rail " clickly " impact sound, noise and violent vibrations not only influence train high-speed smooth operation, but also have a strong impact on the passenger on the train, staff's normal talk, life and rest, influencing railway both sides resident can not quietly have a rest.Simultaneously, the train wheel of load-bearing and the frequent impact between the track interface will damage rail, wheel and connection parts thereof, influence its application life.And the roadbed of laying rail will suffer damage too.How to reduce or eliminate train when rail moves; collision between wheel and the rail joint reduces the pollution of noise to environment, has become many passengers, rail man and environmental protection personnel's the topic of talking about; but, the good plan of this problem that all is not resolved for a long time.
The purpose of this utility model is at above-mentioned situation, a kind of rail of new connected mode is adopted in the joint at rail and rail that proposes, be a kind of novel seam bridge-type rail that has, in the time of effectively solving train and travel along the railway track, the collision problem between train wheel and the rail shrinkage joint.
The method that the utility model is finished is to replace existing rail joint connecting cleat in the outside at existing rail joint place with a bridge-type junction plate.The bridge-type junction plate of new usefulness can play the effect of existing connecting cleat on the one hand, and on the other hand, its top is the same with rail level flat, can play the load-bearing effect that train wheel rolls past tense in the above.Owing to connect the joint of two rails, be communicated with the shrinkage joint between two rails again, so, during train running, wheel is located through the shrinkage joint, and some just rolls across wheel on the bridge-type junction plate, the bridge-type junction plate has been brought into play function served as bridge, make wheel that the rail level that contacts with rail be arranged all the time, the moment at rail shrinkage joint when operation, no longer occurs crossing over fully, realize a smooth transition.So just eliminate the collision at train wheel and rail shrinkage joint place, reduced violent vibrations.
The utility model has the advantages that: simple in structure, make easily, easy for installation, safe and reliable, can effectively realize the steady high-speed cruising of train, reduce vibrations and noise, help passenger and staff's study on the car, have a rest, reduce journey fatigue, reduced the pollution of NOISE ON ENVIRONMENT, can also effectively improve the application life of wheel, rail and roadbed facility, market prospects are good.
Accompanying drawing 1 is an agent structure schematic diagram of the present utility model, and Fig. 2 is the vertical view of Fig. 1.
Most preferred embodiment of the present utility model: the outside in rail (5), (8) joint, the bridge-type junction plate (2) of dress lastblock and connecting cleat (1) adapted, the same flat above the bridge-type junction plate at connection shrinkage joint (9) with rail level (7), bolt (6) passes the installing hole of the mutual adapted of bridge-type junction plate, rail joint end and connecting cleat, fastening nut (3), novel seam bridge-type rail arranged.Yielding rubber layer (4) is housed respectively between bridge-type junction plate, connecting cleat and rail.
Claims (1)
1, a kind of novel seam bridge-type rail that has, comprise rail, connecting cleat, bolt, the installing hole that it is characterized in that utilizing bolt (6) to pass the mutual adapted of bridge-type junction plate (2), rail (5), (8) joint end and connecting cleat (1), fastening nut (3) and in the rail that connects into, the bridge-type junction plate that is communicated with shrinkage joint (9) is installed in the outside at rail joint place, and is the same flat with rail level (7) above.
