Abstract
The utility model relates to a device adopting a bolted type pressing plate to fix tracks, belonging to the technical field of flexible tracks. The device adopting the bolted type pressing plate to fix tracks adopts a compression bolt to fasten tracks through a bolted type pressing plate, a track pressing plate and a rubber nose. A positioning cone frustum on the track pressing plate is matched with the position of a positioning cone hole on the bolted type pressing plate, and an arc groove on the track pressing plate is matched with the position of a bolt hole on the bolted type pressing plate. An inclined plane convex ring on the track pressing plate is matched with the inclined plane inclination of the bolted type pressing plate. The track device plays roles of damping and uniformly distributing load at a contact point of the tracks and the pressing plates through high-strength rubber. Meanwhile, a positioning mechanism, an inclined plane regulating mechanism and a bolt fastening mechanism are arranged between the track pressing plate and the bolted type pressing plate, so the tracks bear certain pretightening force, and the vibration and noises generated equipment running on the tracks are greatly reduced. Meanwhile, the service life of a fixing system is prolonged, the safety factor of the fixing system is increased, and the track device has great economic benefits.

Background technology
High-speed rail transportation can not only improve traffic environment effectively, makes things convenient for the people to go on a journey, but also helps to drive town and country construction and economic development, has remarkable economical and social benefit.Simultaneously Rail Transit System also can be inevitably brought such as the problem of noise, vibration, electromagnetic radiation and influenced view to urban and rural environment, and is wherein particularly outstanding with noise in the train driving and vibration effect.Excessive noise will have a strong impact on the passenger with vibration and track people along the line live normally; On the other hand, noise and vibration also may cause the fatigue damage of relevant devices and structure and surrounding building, reduction of service life.
At present, in subway, lay " steel spring floating slab ", it is a kind of more satisfactory absorption vibration denoise method, reach 30dB according to German field data damping, this system is a kind of quality a---spring system, its basic principle is exactly oscillating mass and the elasticity that increases vibrating body, utilizes its inertia force to absorb impact load, thereby plays the vibration isolation effect.The multiplication factor of this vibrating isolation system under basic vibration frequency is very low, so the effect of vibration and noise reduction highly significant.This method is used in the city of states such as Germany, France, Britain, and is respond well.This method has also been adopted in some track traffics on ground such as Beijing and Shanghai; But because its cost too expensive, every kilometer reaches more than 1,000 ten thousand yuan.
Domestic in addition a lot of city rails adopt some fasteners to fix, and this structure can play the effect of certain vibration and noise reducing, but its result of use is obvious inadequately.
Summary of the invention
In order to reduce the functional reliability of noise pollution and raising track, the utility model provides a kind of employing bolt type pressing plate trapped orbit device.This rail set should be simple in structure, can effectively reduce the noise and the reliability that produce when train is walked in orbit.
The technical solution adopted in the utility model is: a kind of employing bolt type pressing plate trapped orbit device, adopt the track pressing plate that track is fixed on the basis in the track both sides, the bottom on basis is a cement, and pre-embedded bolt and hold-down bolt be set in cement, be provided with clay and billet successively on cement top, between track and billet, be provided with track rubber cushion plate, with the fastening billet of pre-embedded bolt.Described hold-down bolt is fastening track by bolt type pressing plate, track pressing plate and rubber nose.
Described track pressing plate is provided with one and presses nose, a setting circle frustum and a deep-slotted chip breaker, is provided with a circle inclined-plane bulge loop at the upper periphery of deep-slotted chip breaker.
Described bolt type pressing plate is provided with a setting circle taper hole and a bolt hole, is provided with an inclined-plane in the following peripheral of bolt hole.
Described setting circle frustum matches with the position of setting circle taper hole, and described deep-slotted chip breaker matches with the position of bolt hole, and described inclined-plane bulge loop matches with the gradient on inclined-plane.
The beneficial effects of the utility model are: this employing bolt type pressing plate trapped orbit device adopts hold-down bolt fastening track by bolt type pressing plate, track pressing plate and rubber nose.Setting circle frustum on the track pressing plate matches with the setting circle taper hole position on the bolt type pressing plate, deep-slotted chip breaker on the track pressing plate matches with the bolt hole position on the bolt type pressing plate, and the inclined-plane bulge loop on the track pressing plate matches with inclined-plane gradient on the bolt type pressing plate.This rail set is at track and pressing plate contact point, play the effect of damping and uniformly distributed load by high-strength rubber, be provided with detent mechanism, inclined-plane governor motion and bolton mechanism between track pressing plate and the bolt type pressing plate simultaneously, make track bear certain pretightning force, the vibration and the noise that produce when the equipment that greatly reduces is walked in orbit, also improve simultaneously the application life and the safety factor of fixed system, had great economic benefit.
