Description

TECHNICAL FIELD

[0001] The utility model relates to bridge building technical field, especially a kind of vibration reduction and noise reduction modulus formula telescopic device. BACKGROUND

[0002] At present, the telescopic device used in bridge at home and abroad mainly has modulus formula (including single slit), comb plate type, plate type rubber telescopic device etc.. The telescopic device of modulus formula is made of profiled steel of integral forming, and is composed of side beam, middle beam, crossbeam, displacement control system, sealing rubber belt etc., and its structural principle is to convert large gap into small gap. It is manufactured by using profiled steel, and the gap between profiled steel is adapted to displacement, and wheel support surface is formed on the surface of profiled steel, and it is suitable for bridge of various displacement amounts. However, when vehicle passes through the device, wheel moves from one profiled steel to another profiled steel, and the non-continuous contact of wheel and telescopic device will impact the device, and impact noise is generated at the same time, and driving comfort is poor, and repeated impact is also easy to cause damage to the parts of telescopic device, thereby reducing the service life of telescopic device.

[0003] In order to solve the problems of impact and noise, a combined noise reduction telescopic device is developed, such as the utility model patent with the authorization announcement number CN2581484 discloses a "bridge noise reduction telescopic device", and the utility model patent with the authorization announcement number CN201730050U discloses "a bridge noise reduction telescopic device", and the two kinds of telescopic devices adopt the scheme of installing tooth plate on the upper surface of profiled steel of modulus formula telescopic device, so that wheel can be in continuous contact with telescopic device when vehicle drives through the above-mentioned gap, thereby effectively reducing the impact of wheel on each beam and reducing driving noise. But in the disclosed technical scheme, tooth plate is directly contacted with passing vehicle, and when bearing wheel impact load, driving noise is still large, and the ideal requirement of environmental protection and low noise cannot be met.
