Abstract
The utility model relates to a double-decked vibration damping and noise reducing fastener which is particularly easy to assemble and disassemble. The double-decked vibration damping and noise reducing fastener comprises an elastic strip, an insulating spacer, an upper metal plate, elastic strip seats, an insulating track gauge block, a lower metal plate, a track supporting block and an insulating spacer. The double-decked vibration damping and noise reducing fastener is characterized in that the elastic strip seats are arranged at both sides of the upper metal plate, one end of the elastic strip is positioned on the elastic strip seat, the other end of the elastic strip is pressed on the steel rail through the insulating track gauge block, a under-rail cushion is positioned between the upper surface in the middle of the upper metal plate and the bottom of the steel rail, a middle elastic backing plate is arranged under the upper metal plate, the lower metal plate is arranged under the middle elastic backing plate, and the insulating spacer is positioned under the lower metal plate. An anchoring bolt in the anchoring bolt hole of the lower metal plate is connected with the lower metal plate and the track supporting block. A dummy club with a through hole at both ends of the lower metal plate is penetrated through the through hole corresponding to the upper metal plate, and T-shaped bolts and nuts positioned in the through hole of the dummy club are connected with the upper metal plate and the lower metal plate. The double-decked vibration damping and noise reducing fastener has the advantages that when the middle elastic backing plate is replaced, the replacement is not required to be performed after the anchoring bolt is loosened and the lower metal plate is taken out, the operation is convenient, and the operation of the anchoring bolt is ensured to be reliable.
Description
Technical field
The utility model relates to a kind of track vibration damping denoising fastener, is a kind of double-deck vibration and noise reduction fastener of track of mounting or dismounting especially easily.
Background technology
Subway and light rail transit more and more are subjected to the welcome of society greatly and fast and safely because of its freight volume.The fast development of urban track traffic makes the circuit that passes through the urban district increase sharply, vehicle under steam the vibration of sending of wheel and track and noise as not taking measures to have a strong impact on resident's life, though adopt the soft rubber material cushion between rail and sleeper, can reduce vibration and noise simply but can make the distortion of track uncontrollable, bring traffic safety hidden danger, so must the special fastener of design.
Summary of the invention
The purpose of this utility model be separate Now certainly have rail traffic vehicles travel in vibration and noise have a strong impact on the problem of people's life.The utility model design provides a kind of track of easy mounting or dismounting double-deck vibration and noise reduction fastener, comprise spring, felt pad, last iron plate, the spring seat, Insulation rail distance keeper, following iron plate, the rail support piece, felt pad, it is characterized in that: there is the spring seat both sides of going up iron plate, one end of spring rests on the spring seat, the other end is pressed on the rail through the insulation track gauge block by bolt on the last iron plate and nut, on last iron plate middle part and between under the rail, be placed with rubber pad placed under-neath rail, middle resilient sleeper-bearing is arranged below the last iron plate, following iron plate is arranged below middle resilient sleeper-bearing, a felt pad is arranged below the following iron plate.There is the anchor bolt hole at following iron plate two ends, and the anchor bolt that is positioned at the anchor bolt hole connects iron plate and rail support piece down.There is the boss of band through hole at the two ends of following iron plate, and this boss passes iron plate and goes up corresponding through hole, will go up the iron plate location, and are connected iron plate and following iron plate with nut by the tommyhead bolt that is positioned at the boss through hole, are with a resilient sleeve in the boss outside.Through hole on the following iron plate boss is an elongated hole, in via bottoms one inner groovy compatible with tommyhead bolt T shape end is arranged.Advantage of the present utility model: 1. adopt double-deck cushion blocking can reduce the vibration and the noise of track structure effectively; 2. go up iron plate and be with the boss of through hole to locate and be fixed on down on the iron plate, guarantee to transmit rail vertical, horizontal power and uplift force: 3. be beneficial to dismounting because of the employing tommyhead bolt is peculiar to guarantee traffic safety with tommyhead bolt and resilient sleeve by following iron plate going up.Only need to take out tommyhead bolt from top Song Kai And during resilient sleeper-bearing in the middle of changing, can finish after lifting iron plate, need not to unclamp anchor bolt and remake replacing after the iron plate under taking out, easy and simple to handle, Festival saves time, and significantly reduces maintenance workload.In addition, need not unscrew anchor bolt, guarantee the anchor bolt reliable operation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is a structure vertical view of the present utility model
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
Comprise spring 1, felt pad 2, last iron plate 3, spring seat 4, Insulation rail distance keeper 5, following iron plate 6, rail support piece 7 among the figure, it is characterized in that: there is spring seat 4 both sides of going up iron plate 3, one end of spring 1 rests on the spring seat 4, the other end is pressed on the rail 21 through insulation track gauge block 5 by bolt 8 on the last iron plate 3 and nut 9, on last iron plate 3 middle parts and between under the rail 21, be placed with rubber pad placed under-neath rail 10, middle resilient sleeper-bearing 11 is arranged below the last iron plate 3, following iron plate 6 is arranged below middle resilient sleeper-bearing 11, a felt pad 2 is arranged below the following iron plate 6.There is anchor bolt hole 12 at following iron plate 6 two ends, and the anchor bolt 13 that is positioned at anchor bolt hole 12 connects iron plate 6 and rail support piece 7 down.There is the boss 15 of band through hole 14 at the two ends of following iron plate 6, this boss 15 passes through hole 16 corresponding on the iron plate 3, be connected iron plate 3 and following iron plate 6 with nut 18 with last iron plate 3 location and by the tommyhead bolt 17 that is positioned at boss 15 through holes 14, one resilient sleeve 19 arranged in boss 15 outsides.Through hole 14 on following iron plate 6 boss 15 is an elongated hole, have in through hole 14 bottoms one with the compatible inner groovy 20 of the T shape of tommyhead bolt 17 end.It is elasticity that resilient sleeve 19 can make the connection of iron plate 3 and following iron plate 6, with buffering vibration.It is the usefulness of adjusting gauge for adapting to that waist shape is made in anchor bolt hole 12.
When needing to change rubber pad placed under-neath rail 10 and middle resilient sleeper-bearing 11 after the long-term use,, lift rail 21 a little and just can change rubber pad placed under-neath rail 10 as long as unclamp nut 9 and the Insulation rail distance keeper 5 that compresses spring 1; As long as unclamp the nut 18 of tommyhead bolt 17 and tommyhead bolt 17 taken out from boss 15 through holes 14, take out the resilient sleeve 19 that is enclosed within outside the boss 15, lift iron plate 3, it is replaceable middle resilient sleeper-bearing 11, need not to unclamp anchor bolt 13 taking-ups and remake replacing after the iron plate 6 down, this design operation is easy, time saving and energy saving, significantly reduces maintenance workload.Need not unscrew anchor bolt 13 in addition, guarantee anchor bolt 13 reliable operations.
