The present invention relates to the field of rail transit technology, and specifically to a prefabricated plate type shock-absorbing track structure for rail transit turnouts, comprising a rail body and a sleeper body thereunder, and also comprising a groove. When the prefabricated plate type shock-absorbing track structure for rail transit turnouts is in use, a train will first pass over an airbag, and then pass over the sleeper body. At this time, the rail body will first squeeze the airbag, so that the gas in the airbag enters the hollow plate through an air intake pipe, thereby replenishing the gas in the hollow plate and a plurality of buffer grooves. If the air pressure in the buffer groove and the hollow plate is sufficient, the gas in the airbag will be discharged through a plurality of overflow holes outside the overflow pipe. When the rail body squeezes the load-bearing plate, the load-bearing plate will squeeze the buffer plate downward through a plurality of buffer rods, so that the plurality of buffer plates slide in the buffer groove. Since the gas in the hollow plate and the buffer groove cannot be discharged, the gas inside them is compressed, thereby achieving the effect of shock absorbing the train.

When the load-bearing plate 4 is squeezed by gravity, the load-bearing plate 4 will slide on the outer side of the limiting rod 81, and the plurality of limiting rods 81 can limit the falling trajectory of the load-bearing plate 4. The limiting spring 83 arranged on the outer side of the limiting rod 81 can control the load-bearing plate 4 to reset after the rail body 1 is free from squeezing the load-bearing plate 4.

[0045] The replenishing component 6 includes an air storage member 11 arranged on one side of the sleeper body 2, and the air storage member 11 is used to store gas. An air replenishing member 12 is arranged on one side of the sleeper body 2, and the air replenishing member 12 is used to replenish gas for the buffer member 7.

[0046] The air storage member 11 includes a support frame 111 arranged on one side of the sleeper body 2, an airbag 112 is arranged on the top of the support frame 111, a reset plate 113 is arranged in the airbag 112, a plurality of reset springs 114 are arranged at the bottom of the reset plate 113, and the bottom ends of the plurality of reset springs 114 are all arranged in the airbag 112. When the airbag 112 is squeezed, the reset plate 113 moves downward and the plurality of reset springs 114 shrink. When the airbag 112 is free from squeezing, the plurality of reset springs 114 can push the reset plate 113 to reset the airbag 112.

[0047] The air-filling member 12 includes an air inlet pipe 121 arranged on one side of the airbag 112 close to the sleeper body 2, the other end of the air inlet pipe 121 penetrates the sleeper body 2 and is arranged in the hollow plate 71, and the airbag 112 is communicated with the hollow plate 71 through the air inlet pipe 121, an air inlet check valve 122 is arranged in the air inlet pipe 121, and the opening of the air inlet check valve 122 faces the sleeper body 2, an air-filling pipe 123 is arranged on one side of the airbag 112, and an air-filling check valve 124 is arranged in the air-filling pipe 123, and the opening of the air-filling check valve 124 faces the airbag 112. When the airbag 112 is squeezed, the gas in the airbag 112 will enter the air inlet pipe 121 and enter the hollow plate 7 through the air inlet check valve 122. 1 and the buffer groove 73, the hollow plate 71 and the buffer groove 73 are inflated with air, and the reset spring 114 arranged in the airbag 112 will control the reset plate 113 to move upward after the airbag 112 is separated from the extrusion of the rail body 1, and prop up the airbag 112 through the reset plate 113 to reset it. When the airbag 112 is reset, the air replenishment check valve 124 is opened, and the air enters the airbag 112 through the air replenishment pipe 123, so as to prepare for the next extrusion. Its function is that when the train passes over the sleeper body 2, the hollow plate 71 and the buffer groove 73 are first inflated with air through the airbag 112, so as to avoid the phenomenon of insufficient air pressure in the buffer groove 73, which leads to poor shock absorption effect.

[0048] The air intake pipe 121 is provided with a discharge member 13, and the discharge member 13 includes an overflow pipe 131 arranged at the top of the air intake pipe 121, the overflow pipe 131 is communicated with the air intake pipe 121, and the overflow pipe 131 is located between the air intake check valve 122 and the air bag 112, a control ring 132 is arranged in the overflow pipe 131, an overflow plate 133 is arranged at the top of the overflow pipe 131, a control spring 134 is arranged at the bottom of the overflow plate 133, a sealing plate 135 is arranged at the bottom of the control spring 134, a rubber ring 136 is arranged at the bottom of the sealing plate 135, and the rubber ring 136 is located at the top of the control ring 132, and a plurality of overflow holes 137 are opened on the outside of the overflow pipe 131. If the air pressure in the buffer tank 73 and the hollow plate 71 is sufficient, the air entering The gas in the intake pipe 121 cannot enter the hollow plate 71 through the intake one-way valve 122. At this time, the gas in the intake pipe 121 will enter the overflow pipe 131. Under the action of air pressure, the sealing plate 135 in the overflow pipe 131 will be lifted up, so that the rubber ring 136 at the bottom of the sealing plate 135 will separate from the control ring 132. At this time, the gas in the overflow pipe 131 will be discharged through the overflow hole 137. After the gas in the overflow pipe 131 is discharged, the control spring 134 will push the sealing plate 135, so that the sealing plate 135 drives the rubber ring 136 at its bottom to continue to cover the top of the control ring 132. Its function is to discharge excess gas to avoid affecting the normal operation of the airbag 112.

[0049] When in use, the sleeper body 2 is in front and the airbag 112 is in the back. The train will first pass over the airbag 112 and then pass over the sleeper body 2. When the train travels over the rail body 1 and reaches the airbag 112, the rail body 1 will squeeze the airbag 112 due to the weight of the train. When the airbag 112 is squeezed, the gas in the airbag 112 will enter the air intake pipe 121 and enter the hollow plate 71 and the buffer groove 73 through the air intake check valve 122 to replenish the air in the hollow plate 71 and the buffer groove 73. The reset spring 114 arranged in the airbag 112 will control the reset plate 113 to move upward after the airbag 112 is squeezed out of the rail body 1, and prop up the airbag 112 through the reset plate 113 to reset it. When the airbag 112 is reset, the replenishment When the one-way valve 124 is opened, air enters the airbag 112 through the air supply pipe 123, so as to prepare for the next squeezing. If the air pressure in the buffer groove 73 and the hollow plate 71 is sufficient, the gas entering the air intake pipe 121 cannot enter the hollow plate 71 through the one-way valve 122. At this time, the gas in the air intake pipe 121 will enter the overflow pipe 131. Under the action of the air pressure, the air sealing plate 135 in the overflow pipe 131 will be lifted up, so that the rubber ring 136 at the bottom of the air sealing plate 135 will be separated from the control ring 132. At this time, the gas in the overflow pipe 131 will be discharged through the overflow hole 137. When the gas in the overflow pipe 131 is discharged, the control spring 134 will push the air sealing plate 135, so that the air sealing plate 135 drives the rubber ring 136 at the bottom thereof to continue to cover the top of the control ring 132.

[0050] When the train wheel is above the rail body 1, the rail body 1 will press the weight it bears on the load-bearing plate 4. When the load-bearing plate 4 is squeezed by gravity, it will slide on the outside of the limit rod 81. The multiple limit rods 81 can limit the falling trajectory of the load-bearing plate 4. The limit spring 83 arranged on the outside of the limit rod 81 can control the load-bearing plate 4 to reset after the rail body 1 is free from squeezing the load-bearing plate 4. When the load-bearing plate 4 moves downward under the action of the rail body 1, the load-bearing plate 4 will squeeze the buffer rod 75 below it. When the buffer rod 75 is squeezed, the buffer rod 75 will push the buffer plate 74 at its bottom, so that the buffer plate 74 slides in the buffer groove 73 opened in the buffer column 72. Since the buffer groove 73 is connected to the hollow plate 71, When the buffer plate 74 slides downward, the multiple buffer plates 74 will squeeze the gas in the buffer groove 73 and the hollow plate 71, thereby unloading the force on the rail body 1, thereby achieving a shock-absorbing effect on the vibration generated during the train running. The multiple water storage tanks 101 arranged on both sides of the sleeper body 2 can facilitate the staff to pour water into the groove 3 through the water storage tank 101. After the water is poured into the groove 3, when the train runs on the rail body 1 and vibrates, the water flow in the groove 3 can reduce the noise generated by the vibration of the sleeper body 2. The filter plate 102 arranged on the top of the water storage tank 101 can filter rainwater. Filtering rainwater through the filter plate 102 can reduce the workload of the staff, and the staff does not need to add water regularly.

[0051] When the staff needs to inspect the hollow plate 71 and the buffer rod 75, buffer column 72, etc. above it, they push the two locking plates 97 to move the two locking plates 97 to the opposite sides thereof, slide in the corresponding sliding grooves 96, and disengage the two locking plates 97 from the locking grooves 99, and then pull the auxiliary plate 95, which will rotate on the auxiliary rod 92 through two connecting rods 93. At this time, the staff can inspect the hollow plate 71, buffer column 72, etc. in the groove 3. The rubber strip 911 provided on the sleeper body 2 and the auxiliary plate 95 can avoid rigid contact between the load-bearing plate 4 and the auxiliary plate 95 and the sleeper body 2 when the load-bearing plate 4 is pressed down. If the rubber strip 911 needs to be replaced, the rubber strip 911 can be directly pulled off, and the spring piece 910 provided on the auxiliary plate 95 and the sleeper body 2 will automatically shrink, and then it can be directly replaced.

[0052] Example 2

[0053] See also Fig.12 , the present invention provides a technical solution:

[0054] Different from Example 1, the airbag 112 is located in the forward direction of the train. When the train runs on the rail body 1, the wheel will first pass over the sleeper body 2, so that the rail body 1 will preferentially squeeze the load-bearing plate 4, and then the train will continue to run and pass over the airbag 112. At this time, the rail body 1 will squeeze the top of the airbag 112, so that the airbag 112 will replenish air in the hollow plate 71, ensuring that when the next wheel rolls over the rail body 1, the air pressure in the hollow plate 71 and the buffer column 72 is sufficient to reduce the shock of the train.
