Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing and noise-reducing railway sleeper technology, and in particular to a novel sound-absorbing and noise-reducing railway sleeper manufacturing equipment. Background Technology

[0002] As people's demands for the quality of their living environment increase, reducing railway traffic noise pollution has become an urgent task. Traditional railway sleepers generate significant noise during train operation, interfering with the lives, work, and studies of nearby residents. New sound-absorbing and noise-reducing sleeper manufacturing equipment can produce sleepers with better sound absorption and noise reduction performance, effectively reducing the spread of railway noise.

[0003] A search revealed Chinese patent publication number CN211256506U, which discloses a sound-absorbing and noise-reducing railway sleeper structure belonging to the field of rail transit technology. The structure includes a sleeper structure, a vibration-damping structure, and a sound-absorbing structure. The sound-absorbing structure is fixed to the surface of the sleeper structure, and the vibration-damping structure is fixedly nailed to the upper ends of both the sound-absorbing structure and the sleeper structure. The vibration-damping structure includes expansion bolts, a vibration-damping frame, a fixed base, fixing holes, a top block, a vibration-damping spring, and a fixing block. The fixed base is welded and fixed symmetrically at both ends of the vibration-damping frame, and the fixing holes are formed on the surface of the fixed base. The expansion bolts are movable. The device uses a connecting and fixing hole, with the top block built into the inner top of the shock absorber frame. The fixing block is welded and fixed to the middle of the inner side of the shock absorber frame. By setting up sound-absorbing pads and shock absorber frames, the internal shock-absorbing structure of the shock absorber frame can achieve a good shock absorption effect on the track. The sound-absorbing pads can absorb and isolate some noise to achieve a noise reduction effect. It is suitable for the production and use of railway sleeper structures with sound absorption and noise reduction. However, in actual use, the fixing block of this device is welded and fixed to the shock absorber frame. When producing sleepers of different sizes, multiple bolts can only be rotated to replace the shock absorber frame, which is cumbersome and cannot meet the needs of users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of sound-absorbing and noise-reducing sleeper manufacturing equipment, which aims to improve the problem that the existing technology can only rotate multiple bolts to replace the shock absorber frame, which is cumbersome and cannot meet the needs of users.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel sound-absorbing and noise-reducing sleeper manufacturing equipment, comprising a base, a workbench fixedly connected to the top of the base, telescopic rods one fixedly connected at equal intervals on the front and rear sides of the interior of the workbench, a corresponding push plate fixedly connected to one end of each of the multiple telescopic rods one, a bracket fixedly connected to the top left side of the base, a telescopic rod two fixedly connected to the bottom of the bracket, a casting template fixedly connected to the bottom front and rear sides of the telescopic rod two, a table plate fixedly connected to the left side of the workbench, a horizontal plate fixedly connected to the top front and rear sides of the table plate, a conveyor belt fixedly connected to the adjacent side of two horizontal plates, and a noise reduction mechanism provided on the top of the workbench.

[0006] The above technical solution involves using telescopic rod one to push the corresponding push plate, ensuring that the shape and size of the sleeper meet the requirements. Telescopic rod two can extend and retract vertically. When a pouring operation is required, telescopic rod two extends downward, causing the pouring templates on the front and rear sides of the bottom to descend. The pouring templates are used to define the external shape of the sleeper, ensuring that the poured sleeper has accurate dimensions and shape. At the same time, the conveyor belt between the two horizontal plates starts to operate, transporting the prepared sleeper away, thus realizing an automated production process.

[0007] As a further description of the above technical solution:

[0008] The noise reduction mechanism includes a track pillow, which is set on the top of the workbench. A porous ceramic is fixedly connected to the top of the track pillow, and a fiber fabric is fixedly connected to the outer wall of the porous ceramic. A rubber pad is fixedly connected to the bottom of the track pillow, and a protective shell is fixedly connected to both the left and right sides of the track pillow.

[0009] Through the above technical solution: when the train is running, the sleeper bears the pressure from the rail and generates vibration. The porous ceramic and fiber fabric can effectively absorb and dissipate high-frequency vibration energy and convert it into heat energy. The rubber pad further buffers low-frequency vibration and reduces the transmission to the ground. The protective shell protects the sleeper from the influence of the external environment and ensures its long-term stable operation.

[0010] As a further description of the above technical solution:

[0011] A switch is fixedly connected to the left side of the bracket, and the switch is electrically connected to telescopic rod one and telescopic rod two.

[0012] Through the above technical solution: the switch is fixedly connected to the left side of the bracket and electrically connected to telescopic rod one and telescopic rod two, controlling the working state of telescopic rod one and telescopic rod two.

[0013] As a further description of the above technical solution:

[0014] An observation window is provided on the left side of the bracket, and a sealing ring is fixedly connected to the left side of the observation window.

[0015] The above technical solution allows for the observation window to be located on the left side of the bracket, facilitating operators to observe the internal working conditions during equipment operation.

[0016] As a further description of the above technical solution:

[0017] Both ends of the bottom right side of the platform are fixedly connected to support legs. The bottom of the support legs and the bottom front and rear sides of the base are fixedly connected to support feet. The bottom of each of the support feet is fixedly connected to a soft pad.

[0018] The above technical solution, with support feet fixed to the bottom of the outriggers and the front and rear sides of the base, further enhances the stability of the entire device. Soft pads located at the bottom of the support feet provide cushioning and shock absorption.

[0019] As a further description of the above technical solution:

[0020] The top front and rear sides of the platform are fixedly connected to baffles, and the adjacent sides of the two baffles are respectively fixedly connected to one side of the horizontal plate.

[0021] The above technical solution provides protection for the conveyor belt, preventing external objects from accidentally impacting the conveyor belt and affecting its normal operation.

[0022] As a further description of the above technical solution:

[0023] Protective pads are fixedly connected to adjacent sides of both baffles, and grooves are equally spaced on adjacent sides of both protective pads.

[0024] The above technical solution involves fixing the protective pad to one side of the baffle, which can prevent objects from being damaged by hard collisions with the baffle during transportation, thus providing a buffering and protective function.

[0025] As a further description of the above technical solution:

[0026] The same triangular sliding plate is fixedly connected to the left side of both horizontal plates, and the bottom of the triangular sliding plate is fixedly connected to the top right side of the workbench.

[0027] The above technical solution serves to guide the transition of objects from the conveyor belt to the workbench.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the push plate is pushed by the first telescopic rod to ensure that the shape and size of the sleeper meet the requirements, and the second telescopic rod drives the casting template to descend, limiting the external shape of the sleeper to ensure accurate dimensions. At the same time, the conveyor belt between the horizontal plates operates. This equipment realizes the efficient production of sleepers of different sizes and provides reliable technical support for sleeper manufacturing.

[0030] 2. In this utility model, when the sleeper bears the pressure of the rail and generates vibration, the porous ceramic and fiber fabric effectively absorb and dissipate the high-frequency vibration energy and convert it into heat energy, the rubber pad buffers the low-frequency vibration and reduces the transmission to the ground, and the protective shell protects the sleeper from the influence of the external environment. This achieves the noise reduction effect of the sleeper when it is subjected to pressure and vibration, ensures its long-term stable operation, and improves the performance and service life of the sleeper.

A workbench 3 is fixedly connected to the top of the base 1. The workbench 3 is the main operating platform for sleeper manufacturing. Telescopic rods 4 are equidistantly fixedly connected to the front and rear sides of the workbench 3. The telescopic rods 4 push corresponding push plates 5 through telescopic movement.

The conveyor belt 11 transports raw materials to the workbench 3 or transports the finished sleeper away. The top of the workbench 3 is equipped with a noise reduction mechanism 2. The noise reduction mechanism 2 realizes the sound absorption and noise reduction function of the sleeper.

[0040] Specifically, firstly, the corresponding push plate 5 is pushed by the telescopic rod 4 to ensure that the shape and size of the sleeper meet the requirements. The telescopic rod 7 can extend and retract up and down. When the pouring operation is required, the telescopic rod 7 extends downward, driving the pouring template 8 on the front and rear sides of the bottom to descend. The pouring template 8 is used to limit the external shape of the sleeper to ensure that the poured sleeper has accurate size and shape. At the same time, the conveyor belt 11 between the two horizontal plates 10 starts to operate. The conveyor belt 11 transports the prepared sleeper away to produce sleepers of different sizes.

[0041] Reference Figure 1 and Figure 5The track sleeper 201 has a porous ceramic 202 fixedly connected to its top. The porous ceramic 202 absorbs noise by utilizing its numerous tiny pores. A fiber fabric 203 is fixedly connected to the outer wall of the porous ceramic 202. The fiber fabric 203 protects the porous ceramic 202 and assists in sound absorption. A rubber pad 204 is fixedly connected to the bottom of the track sleeper 201. The rubber pad 204 reduces vibration and noise through its good elasticity and damping performance. Protective shells 205 are fixedly connected to both the left and right sides of the track sleeper 201.

[0042] Specifically, the sleeper 201 bears the pressure from the rails and generates vibrations. The porous ceramic 202 and fiber fabric 203 can effectively absorb and dissipate high-frequency vibration energy and convert it into heat energy. The rubber pad 204 further buffers low-frequency vibrations and reduces the transmission to the ground. The protective shell 205 protects the sleeper 201 from the influence of the external environment and ensures its long-term stable operation.

[0044] Specifically, the working status of telescopic rod 4 and telescopic rod 7 can be controlled by operating switch 12, which can easily start or stop the telescopic rod's extension and retraction. The observation window 13 is located on the left side of the bracket 6, allowing the operator to observe the internal working conditions during equipment operation. The support feet 16 are fixed to the bottom of the support legs 15 and the bottom front and rear sides of the base 1, respectively, further enhancing the stability of the entire equipment. The soft pad 17 is located at the bottom of the support feet 16, playing a role in buffering and shock absorption.

[0045] Reference Figure 2 and Figure 3Baffles 18 are fixedly connected to the front and rear sides of the top of the platform 9. The baffles 18 prevent objects on the conveyor belt 11 from falling from both sides. The adjacent sides of the two baffles 18 are fixedly connected to one side of the horizontal plate 10. The adjacent sides of the two baffles 18 are fixedly connected to protective pads 19. The protective pads 19 play a buffering and protective role and increase friction to prevent objects from sliding. The adjacent sides of the two protective pads 19 are provided with grooves 20 at equal intervals. The grooves 20 further increase friction to ensure the stability of the objects. The left side of the two horizontal plates 10 is fixedly connected to the same triangular slide plate 21. The triangular slide plate 21 plays a transitional guiding role to smoothly transfer the raw materials to the worktable 3. The bottom of the triangular slide plate 21 is fixedly connected to the top right side of the worktable 3.

[0046] Specifically, the baffle 18 is fixedly connected to the front and rear sides of the top of the platform 9. Its main function is to prevent items on the conveyor belt 11 from falling off the sides during transportation. The protective pad 19 is fixed to one side of the baffle 18 to prevent objects from being damaged by hard collisions with the baffle 18 during transportation. It plays a transitional guiding role in the process of transporting objects from the conveyor belt 11 to the worktable 3, so that objects can be smoothly transferred from the conveyor belt 11 to the worktable 3.

[0047] Working principle: When using the new sound-absorbing and noise-reducing sleeper preparation equipment, the corresponding push plate 5 is first pushed by the telescopic rod 4 to ensure that the shape and size of the sleeper meet the requirements. The telescopic rod 7 can extend and retract up and down. When the casting operation is required, the telescopic rod 7 extends downward, driving the casting template 8 on the bottom front and rear sides to descend. The casting template 8 is used to limit the external shape of the sleeper to ensure that the cast sleeper has accurate size and shape. At the same time, the conveyor belt 11 between the two horizontal plates 10 starts to operate. The conveyor belt 11 transports the prepared sleeper away to produce sleepers of different sizes.

[0048] Furthermore, when using the new sound-absorbing and noise-reducing sleeper, the sleeper 201 bears the pressure from the rail and generates vibration. The porous ceramic 202 and fiber fabric 203 can effectively absorb and dissipate high-frequency vibration energy and convert it into heat energy. The rubber pad 204 further buffers low-frequency vibration and reduces the transmission to the ground. The protective shell 205 protects the sleeper 201 from the influence of the external environment and ensures its long-term stable operation.
