Background technology
Existing bridge extension joint is that stretching device is arranged between two beam body abutting ends or between beam-ends and abutment.Existing stretching device be all bolt only in fixed end anchoring, bolt adopts two row or more rows, telescopic end is freely placed, vehicle is through out-of-date easy generation vibrations and noise, and installation complexity, repair and replacement are difficult, bolt easily cut off and the life-span low.
Utility model content
The purpose of this utility model is to provide that a kind of vehicle is little through out-of-date vibrations, can carry out infinitely variable cambered surface damping bridge extension joint between component fitting face.
Overall structure of the present utility model is:
Cambered surface damping bridge extension joint, comprise that two ends set up the main tooth plate at beam body spaced apart or beam body and abutment upper surface, the upper surface of beam body is fixed in main tooth plate one end, main tooth plate movable end one side interval plug-in mounting is provided with secondary tooth plate, the beam body upper surface of main tooth plate and secondary tooth plate soffit is provided with backing plate, between beam body upper surface spaced apart, is provided with band; Described main tooth plate is by cambered surface rotating mechanism and the fixing assembling of beam body upper surface, and the soffit of cambered surface rotating mechanism and beam body top are fixed.
Concrete structure design of the present utility model also has:
Cambered surface rotating mechanism preferably adopts following frame mode, and described cambered surface rotating mechanism comprises longitudinally stacked, and adjacent surface is cambered surface notch plate and the cambered surface convex plate of cambered surface adaptation, band one side be arranged at cambered surface notch plate and cambered surface convex plate between.
For guarantee main tooth plate can vehicle by time can adjust flexibly between cambered surface rotating mechanism each component fitting face, preferred technical scheme is, between described main tooth plate, cambered surface notch plate, cambered surface convex plate, be gap assembling, and be an integral body by anchor bolt cross-under.
For simplifying the assembling of anchor bolt and bolt, do not affect the planeness on main tooth plate and secondary tooth plate surface simultaneously, the needs that pass through to meet vehicle, preferably assembling mode is, described anchor bolt adopts dormant bolt, and the nut of anchor bolt is located in the counterbore of offering on main tooth plate surface.Secondary tooth plate is by bolt and embedded sleeve barrel secure fit.More preferred embodiment, described bolt adopts dormant bolt, and the nut of bolt is located in the counterbore of offering on secondary tooth plate surface.
For realizing the fixing of cambered surface rotating mechanism and beam body, preferred embodiment, the soffit of described cambered surface rotating mechanism is fixedly connected with the embedded bar of beam body.
Operating principle of the present utility model is:
When bridge normally moves, cambered surface damping bridge extension joint is consistent with the working condition of common tooth plate stretching device.When vehicle passes through, owing to having fit clearance between the cambered surface notch plate of cambered surface rotating mechanism and cambered surface convex plate, between cambered surface notch plate and cambered surface convex plate, can produce micro-relative motion, effectively reduce the vibrations that produce through out-of-date main tooth plate because of vehicle, reduced the noise that between stretching device component, collision produces.Because bolt has adopted the mode that screws from top to bottom, be easy to install and change.
The obtained technological progress of the utility model is:
1, the utility model is owing to having adopted the principle of cambered surface rotating mechanism, make vehicle by time fit clearance between main tooth plate and backing plate little, the vibrations that vehicle produces through out-of-date stretching device component collision have effectively been reduced, reduce noise, avoided the phenomenon of easily cutting off because of the bolt that stretching device vibrations cause simultaneously.
2, the bolt of fixing main tooth plate and secondary tooth plate adopts dormant bolt, is not affecting under the prerequisite of use, and bolt is easy to realize to be installed and change.
