Abstract
A damping plate for a stationary type rail using a clamp comprises damping plates stuck to the upper surface at the bottom of the rail and on the wed of the rail; a limiting plate is fixed on the outer lateral wall of each damping plate, so that composite damping plates are formed; the two composite damping plates are clamped and fixed by elastic clamps; jaws at the upper ends of the elastic clamps are propped against the outer sides of the composite damping plates; two lower ends of clamp handles symmetrically extend to the lower part of the rail; a compression spring is clamped between the two clamp handles; a bolt transversally passes through the two clamp handles and the compression spring, and the end part thereof is fastened by a nut. The utility model mainly adopts the comprehensive connection technology through relying mainly on the dedicated clamp while taking the bonding technology as the subsidiary to fix the rail damping plate and the rail, thereby greatly improving the installation efficiency and conveniently being replaced and maintained, effectively ensuring that the sticking strength and the fatigue life of the composite damping plates, and simultaneously avoiding the bridge connection of the rail and the limiting plate, and ensuring the vibration damping and noise reducing effect.
Description
Technical field
The utility model relates to a kind of steel wheel rail traffic system track vibration damping denoising device.
Background technology
In order to reduce vibration and the influence of noise of steel wheel rail traffic system track use to environment, known technology is to paste the rail damping sheet in the rail two sides, known rail damping sheet is to be made by high damping material, external by a kind of composite damping plate of being made up of damping sheet and one deck restraining plate, they have following deficiency and defective:
1, the mounting process complexity of damping sheet, replacing and maintenance inconvenience, cause can't high volume applications in actual engineering.
2, the effect of vibration and noise reduction of damping sheet is subjected to the influence of bond quality bigger, and damping sheet only is connected with rail by cementing agent, and it is lower to stick intensity, mass of vibration is little, and under the long-term dynamic load effect of train, damping sheet easily and rail peel off, thereby lose effect of vibration and noise reduction.
3, after composite damping plate mass of vibration increases, be difficult to more fixedly connected with rail, and adopt the reinforcing that is rigidly connected such as bolt riveted joint, can between rail and restraining plate, form vibration and noise transfer " bridge " again, the vibration noise of rail will be delivered to restraining plate through this " bridge ", and to extraneous radiation, cause effect of vibration and noise reduction to descend greatly, therefore, its application is subjected to bigger restriction.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of anchor clamps fixed steel rail damping sheet, solve damping sheet and be connected technical problem not firm, that effect of vibration and noise reduction is not good enough with rail.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of anchor clamps fixed steel rail damping sheet, comprise the damping sheet that sticks on the rail flange of rail upper surface and the web of the rail, it is characterized in that: the lateral surface of every damping sheet is one deck restraining plate fixedly, form the composite damping plate thus, two composite damping plates are held fixing by an elastic clip clamp, the upper end jaw roof pressure of elasticity clamp is in composite damping plate outside, pincers handle two lower end symmetries extend to the below of rail, a compression of clamping spring between the two pincers handles, be horizontally through two pincers handles and compression spring by bolt, its end is fastening by nut.
Can be lined with pad between above-mentioned compression spring and the elasticity clamp.
The jaw of above-mentioned elasticity clamp can be ㄈ shape or C shape.
The utility model pastes on the rail surface and adds the composite damping plate that is made of high damping material and constraint sheet material, and is fixed by spring chuck in its outside, has significantly reduced the vibration of rail, thereby has effectively reduced vibration and influence of noise to environment.
The beneficial effects of the utility model:
1, adopting based on spring chuck, bonding technology is the comprehensive connection technology of assisting, spring chuck by easy, suitable dismounting, effectively guaranteed sticking intensity and fatigue life of composite damping plate, improved installation effectiveness greatly, and be convenient for changing and keep in repair, do not influence maintenance work such as switch tracks.
2, adopt spring chuck fixedly connected, avoided " bridge joint " of rail and restraining plate, effectively improve effect of vibration and noise reduction.
3, adopt spring chuck in conjunction with bonding dual connection, by spring chuck bonding and that buckle press is controlled, guaranteed the bond strength of rail and composite damping plate, can be under the prerequisite of the bond strength that effectively guarantees composite damping plate and rail, increase the weight of damping sheet and restraining plate, can select the big restraining plate of bigger damping sheet and quality for use.Make the mass of vibration of rail increase greatly, and improved effect of vibration and noise reduction thus.
4, spring chuck pressure is controlled, can effectively guarantee long-term vibration and noise reducing ability, and effect of vibration and noise reduction is more remarkable.The effect of vibration and noise reduction that the utility model has solved damping sheet is subjected to the bigger problem of influence of bond quality, by the buckle press of regular adjustment anchor clamps, can guarantee the long-term effectiveness in vibration suppression of damping sheet.
5, the utility model belongs to higher damper rail equipment, compares with common rail, and every kilometer cost of single line only increases by 400,000 yuan, and Technological Economy is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Reference numeral: 1-rail, 2-damping sheet, 3-restraining plate, 4-elasticity clamp, 5-bolt, 6-nut, 7-compression spring, 8-pad.
The specific embodiment
Embodiment is referring to shown in Figure 1, this anchor clamps fixed steel rail damping sheet, comprise the damping sheet 2 that sticks on rail 1 flange of rail upper surface and the web of the rail, the lateral surface of every damping sheet 2 is one deck restraining plate 3 fixedly, form the composite damping plate thus, two composite damping plates are gripped by an elasticity clamp 4, and the upper end jaw roof pressure of elasticity clamp 4 is in composite damping plate outside, and jaw can be ㄈ shape or C shape.Pincers handle two lower end symmetries extend to the below of rail 1, and a compression of clamping spring 7 between the two pincers handles is horizontally through two pincers handles, compression spring 7 and pad 8 by bolt 5, and its end is fastening by nut 6.
