Description

Technical Field

[0001] The utility model relates to the field of railway noise reduction, in particular to a vibration and noise reduction device for sleeper production. Background Art

[0002] Sleepers are a vital component of railway track structures. Their primary function is to support the track, distribute the loads generated by passing trains, protect the roadbed from direct pressure, and provide track stability and durability. The sleeper production process involves multiple steps. For concrete sleepers, for example, the production process typically begins with the storage and delivery of raw materials at a batching and mixing plant, followed by the distribution and compaction of concrete in molds. The molds are then transferred to a curing room for curing to ensure early strength and improve production efficiency. The curing process includes a rest period, a heating period, a constant temperature period, and a cooling period. Following steam curing, the sleepers are de-stressed using a tensioning machine, which cuts off excess steel wire and removes the finished product from the mold—a process known as demolding. Finally, the finished sleepers are transported to an open-air warehouse for stacking and undergo necessary sampling inspections, such as static load crack resistance and dimensional testing.

[0003] Mortar compaction is a crucial step in the production of concrete sleepers. Vibration equipment uses vibration to compact the cement mortar, ensuring the density and uniformity of the concrete. The operating principle of cement mortar compaction equipment is that a synchronous motor drives a cam, causing the vibrating component to rise and fall after reaching a certain height, generating vibration. A proximity switch is used for automatic counting control, generally stopping after 60 cycles. However, this vibration process may generate some noise, especially when vibrating the mortar. Due to the frequency and amplitude of the vibration, the vibration noise may be high, which may have a certain impact on the surrounding environment.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0027] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0028] 1. The embodiment of the present invention provides a shock-absorbing and noise-reducing device for sleeper production. The device can be set in a pit or on the ground. Through shock absorption, the mortar vibration equipment is stably supported without affecting the existing mortar vibration process. The base plate is used to be installed on the ground or at the bottom of the pit to support the shock-absorbing platform. The shock-absorbing platform provided by the embodiment of the present invention is shock-absorbing by a support mechanism set between the shock-absorbing platform and the base plate. The support mechanism can reduce and transform the excess vibration energy generated in the mortar vibration process. Specifically, the support mechanism includes a vertical compression mechanism and at least one diagonal support moving mechanism. The vertical compression mechanism and the diagonal support moving mechanism can not only stably support the shock-absorbing platform, but also the height of the vertical compression mechanism can be elastically changed. The vertical compression mechanism can reduce the vertical vibration transmitted to the shock-absorbing platform by the mortar vibration equipment. The inclination angle of the diagonal support moving mechanism can be elastically changed. The diagonal support moving mechanism can reduce the horizontal or inclined vibration transmitted to the shock-absorbing platform by the mortar vibration equipment. Through the joint cooperation of the vertical compression mechanism and the diagonal support moving mechanism, the residual vibration energy in multiple directions generated by the mortar compaction equipment can be significantly weakened, thereby achieving the purpose of reducing residual vibration, thereby reducing vibration noise and protecting the non-vibrating parts of the mortar compaction equipment.

[0029] 2. The vertical compression mechanism of the present invention provides a stable support structure by cooperating between the movable groove on the pier and the movable rod. Furthermore, by providing a first elastic component within the movable groove, the movable rod is allowed to move vertically within the groove, thereby reducing the vertical vibration energy of the shock-absorbing platform. The first slider guides and limits the vibration direction of the movable rod, thereby improving the stability of the vertical compression mechanism. Because the movable groove, first elastic component, first slider, and movable rod are connected in series, the movable rod is prevented from dislodging from the movable groove.

[0030] 3. A slide groove is set on the bottom plate, and a second slider and a second elastic component are set in the slide groove. The second elastic component is fixed on the slide groove wall and then connected to the second slider. The diagonal support rod is connected to the second slider, so that the diagonal support rod can support the shock-absorbing platform, and the diagonal support rod is hinged to the shock-absorbing platform, that is, the diagonal support rod can rotate relative to the shock-absorbing platform. The diagonal support rod can rotate to a certain extent during the vibration of the shock-absorbing platform. Since the total length of the diagonal support rod remains unchanged, the second slider will be driven to slide in the slide groove during the rotation of the diagonal support rod, and the second spring can play a role in lateral and diagonal shock absorption.

[0031] In general, the shock-absorbing and noise-reducing device provided in the embodiment of the utility model provides a shock-absorbing platform for the mortar compaction equipment. The shock-absorbing platform can reduce the residual vibration generated by the mortar compaction equipment in multiple directions through the diagonal support moving mechanism, so as to achieve the purpose of reducing the excessive vibration noise during the production process of smaller sleepers, avoiding environmental noise pollution and damage to the non-vibration parts of the mortar compaction equipment.

[0042] Example

[0043] The embodiment of the utility model provides a vibration and noise reduction device for sleeper production, which can be installed in a pit or on the ground, without limitation. Figure 1As shown, it specifically includes: a shock-absorbing platform 1, which is used to support the mortar vibration compaction equipment and bear the weight of the vibration compaction equipment and the dynamic load during operation. The base plate 2 is arranged below the shock-absorbing platform 1, and is used to support the shock-absorbing platform 1. It is installed on the ground or at the bottom of the pit to form a stable support. It is generally a plate-shaped structure, which can increase the contact area with the ground or the bottom of the pit and increase stability. There are several supporting mechanisms 3. The specific number of settings can be determined according to the actual load that needs to be borne. There is no restriction here. Each supporting mechanism 3 includes a vertical compression mechanism 4 and at least one diagonal support moving mechanism 5; the top of the vertical compression mechanism 4 is connected to the shock-absorbing platform 1, and the bottom thereof is connected to the base plate 2. The vertical compression mechanism 4 and the diagonal support moving mechanism 5 can jointly support the shock-absorbing platform 1 and the equipment on the shock-absorbing platform 1. The top of the diagonal support moving mechanism 5 is hinged to the shock-absorbing platform 1. The hinged structure allows the angle between the diagonal support moving mechanism 5 and the shock-absorbing platform 1 to change, and its bottom is slidably connected to the base plate 2. When the angle between the diagonal support moving mechanism 5 and the shock-absorbing platform 1 changes, relative sliding will occur between the diagonal support moving mechanism 5 and the base plate 2; the height of the vertical compression mechanism 4 can be elastically changed, and the inclination angle of the diagonal support moving mechanism 5 can be elastically changed.

[0044] For example, Figure 2 As shown, the vertical compression mechanism 4 includes a pier 6 and a moving rod 7. The pier 6 is fixedly arranged on the base plate 2, and a moving groove 8 is provided at the top opening. The top of the moving rod 7 is connected to the shock-absorbing platform 1, and its bottom is movably inserted into the moving groove 8. A first elastic component 9 is provided in the moving groove 8. The first elastic component 9 can drive the moving rod 7 to move vertically in the moving groove 8. Specifically, the pier 6 is fixed on the base plate 2, and an opening is designed at the top to form the moving groove 8 for accommodating the moving rod 7. The top of the moving rod 7 is connected to the shock-absorbing platform 1, and the bottom is movably inserted into the moving groove 8. The setting of the moving rod 7 allows it to move vertically in the moving groove 8, thereby absorbing vibration. The first elastic component 9 is provided in the moving groove 8 to drive and limit the moving rod 7 to move vertically in the moving groove 8. The first elastic component 9 can be a spring, a rubber pad or other types of elastomers, which are not limited here. Preferably, the first elastic component 9 is a spring. The first elastic component 9 absorbs vibration energy through its elastic deformation, reducing the vibration transmitted to the shock-absorbing platform 1 and the base plate 2. The vertical movement of the moving rod 7 in the moving groove 8 allows the device to adapt to vibrations of different amplitudes and provide a wider range of shock-absorbing effects. The fixed setting of the pier 6 ensures the stability of the entire vertical compression mechanism 4 and prevents displacement or tilting during vibration. During actual operation, the height of the moving rod 7 in the moving groove 8 is adjustable, and its shock-absorbing effect can be adjusted according to actual needs. This structure can effectively reduce the excess noise and vibration generated by the compaction equipment during operation, thereby improving the comfort of the production environment and the service life of the equipment.

[0045] As a preferred embodiment of the present invention, a first slider 10 is provided in the movable groove 8, one end of the first elastic component 9 is connected to the bottom of the movable groove 8, and the other end is connected to the bottom of the first slider 10, the bottom of the movable rod 7 is connected to the first slider 10, the outer diameter of the first slider 10 is adapted to the inner diameter of the movable groove 8, and the first slider 10 can move in the vertical direction along the movable groove 8. Specifically, the first slider 10 is located in the movable groove 8, the outer diameter is adapted to the inner diameter of the movable groove 8, and can move in the vertical direction along the movable groove 8. The first elastic component 9 is connected to the bottom of the movable groove 8 at one end, and the other end is connected to the bottom of the first slider 10, providing elastic force to drive the infrared limiter to move the first slider 10 in the movable groove 8. The movable top is connected to the shock-absorbing platform 1, and the bottom is connected to the first slider 10. The vertical movement in the movable groove 8 is realized by the first slider 10. More specifically, the first elastic component 9 (such as a spring) provides an upward or downward elastic force to the first slider 10, driving and limiting the first slider 10 to move up and down in the movable groove 8, thereby driving the movable rod 7 to move up and down to achieve vibration absorption. The outer diameter of the first slider 10 is adapted to the inner diameter of the movable groove 8 to ensure stability and reduce friction during movement. The connection method of the first elastic component 9 ensures the stability of the movable rod 7 during vibration to prevent excessive movement or disengagement.

[0046] Further, if Figure 3As shown, a slide groove 11 with an upper end opening is provided on the base plate 2, and the diagonal support moving mechanism 5 includes a diagonal support rod 12 and a second slider 13. The second slider 13 is arranged in the slide groove 11 and can slide along the slide groove 11; one end of the diagonal support rod 12 is hinged to the shock absorbing platform 1, and the other end is connected to the second slider 13; a second elastic component 14 is provided in the slide groove 11, one end of the second elastic component 14 is connected to the side wall of the slide groove 11, and the other end is connected to the second slider 13; when the vertical compression mechanism 4 changes to the longest total length, the second slider 13 is located at one end of the slide groove 11; when the vertical compression mechanism 4 changes to the shortest total length, the second slider 13 is located at the other end of the slide groove 11, and under the action of gravity, the second slider 13 can always keep in contact with the bottom wall of the slide groove 11. Specifically, a chute 11 with an open top is provided on the base plate 2 to guide the movement of the second slider 13, allowing the diagonal support rod 12 to move diagonally or laterally on the base plate 2. One end of the diagonal support rod 12 is hinged to the shock-absorbing platform 1, and the other end is connected to the second slider 13, forming a diagonal support structure. A second elastic component 14 is provided in the chute 11, with one end connected to the side wall of the chute 11 and the other end connected to the second slider 13, providing elastic force to drive and limit the movement of the second slider 13 along the chute 11. In the embodiment of the present utility model, the provision of the diagonal support rod 12 allows the device to absorb vibration in multiple directions, such as horizontally or diagonally. The second elastic component 14 provides a restoring force, enabling the diagonal support rod 12 to dynamically adjust its position according to the vibration conditions. The change in the position of the second slider 13 in the chute 11 realizes the adjustment of the inclination angle of the diagonal support rod 12 to adapt to different shock-absorbing requirements. The design of the chute 11 enables the diagonal support moving mechanism 5 to be compactly integrated on the base plate 2, saving space. The hinged connection between the diagonal support rod 12 and the shock-absorbing platform 1 and the cooperation between the second slider 13 and the slide groove 11 ensure the stability of the structure. The support moving mechanism can automatically adjust its position according to the length change of the vertical compression mechanism 4 to achieve the best shock-absorbing effect.

[0047] Preferably, each support mechanism 3 includes a vertical compression mechanism 4 and two diagonal support moving mechanisms 5. The vertical compression mechanism 4 is arranged in the middle of the two diagonal support moving mechanisms 5. The two diagonal support moving mechanisms 5 are axially symmetrical with respect to the axis of the vertical compression mechanism 4. Specifically, the two diagonal support moving mechanisms 5 are arranged axially symmetrical with respect to the axis of the vertical compression mechanism 4, which provides balance and stability of the structure. In order to further improve the balance and stability, a support mechanism 3 can be respectively arranged at the four corners of the base plate 2, that is, four support mechanisms 3 simultaneously support and absorb shock to the shock absorbing platform 1, which can improve support stability and shock absorption efficiency. Of course, in other embodiments, the number of support mechanisms 3 and the position layout of multiple support mechanisms 3 are not limited here, as long as the purpose of sufficient stability and support strength can be achieved. Back to the embodiment of the present invention, the vertical compression mechanism 4 is responsible for absorbing vibrations in the vertical direction, while the two diagonal support moving mechanisms 5 absorb horizontal or diagonal vibrations, together forming a multi-directional shock absorption system. The vertical compression mechanism 4 is located in the center and serves as a positioning reference for the entire support mechanism 3, which helps to maintain the geometric center of the structure and the balance of force. The symmetrical layout helps to more evenly disperse the vibration force generated by the compaction equipment. The axially symmetrical structure reduces the torsion or deviation caused by vibration and increases the overall stability.

[0048] Similarly, in a single support mechanism 3, there is no restriction on the number of diagonal support moving mechanisms 5. Only one diagonal support moving mechanism 5 may be provided, or three, four, or the like diagonal support moving mechanisms 5 may be provided. When multiple diagonal support moving mechanisms 5 are provided, there is no restriction on the angle setting of two adjacent diagonal support moving mechanisms 5.

[0049] In order to better reduce the impact of noise, in an embodiment of the present invention, a first mounting groove 15 and a second mounting groove 16 are respectively provided on two relatively long sides of the top surface of the shock-absorbing platform 1, and a sound insulation board mechanism is movably installed on the first mounting groove 15 and the second mounting groove 16. Specifically, the first mounting groove 15 and the second mounting groove 16 are respectively provided on two relatively long sides of the top surface of the shock-absorbing platform 1 for installing the sound insulation board mechanism, that is, the sound insulation board mechanism and the shock-absorbing platform 1 are detachably installed. It is only necessary to install the sound insulation board mechanism before the mortar vibration operation link. After the mortar vibration operation link is completed, the sound insulation board mechanism can be disassembled, providing convenience for installation and disassembly, and facilitating maintenance and adjustment. The sound insulation board can be adjusted according to the actual noise level and working environment to achieve the best sound insulation effect. The sound insulation board mechanism helps to form a sound insulation area on the shock-absorbing platform 1 to reduce the impact of noise on the surrounding environment. Exemplarily, the sound insulation mechanism has an open lower end and includes a first sound insulation panel 17 and a second sound insulation panel 18, with the tops of the first sound insulation panel 17 and the second sound insulation panel 18 intersecting. The bottom of the first sound insulation panel 17 is mounted in the first mounting slot 15, while the bottom of the second sound insulation panel 18 is mounted in the second mounting slot 16. Specifically, the first sound insulation panel 17 is mounted in the first mounting slot 15 of the vibration-damping platform 1, with its bottom fixed and its top intersecting with the second sound insulation panel 18. The second sound insulation panel 18 is mounted in the second mounting slot 16 of the vibration-damping platform 1, with its bottom fixed and its top intersecting with the first sound insulation panel 17. The combination of the first sound insulation panel 17 and the second sound insulation panel 18 forms a two-way sound insulation structure, improving the sound insulation effect. The intersecting tops of the two sound insulation panels help reduce the path for sound to propagate between the panels.

[0050] In order to prevent the sound insulation mechanism from excessively sliding in the mounting groove and falling off the mounting groove when being driven to vibrate by the shock-absorbing platform 1, a first screw hole mechanism 19 can be provided at both ends of the first mounting groove 15, and a second screw hole mechanism 20 can be provided at both ends of the second mounting groove 16. A screw 21 can be movably inserted into each of the first screw hole mechanisms 19 and the second screw hole mechanisms 20, and the screw 21 can limit the sound insulation board mechanism from being separated from the first mounting groove 15 and the second mounting groove 16. Specifically, the first screw hole mechanism 19 and the second screw hole mechanism 20 are respectively provided at both ends of the first mounting groove 15 and the second mounting groove 16 for inserting the screw 21. The screw 21 can be movably inserted into the first screw hole mechanism 19 and the second screw hole mechanism 20 to fix the sound insulation board mechanism and prevent it from being separated from the mounting groove. When the sound insulation board mechanism needs to be disassembled, only the screw 21 needs to be removed. The use of the screw 21 provides a stable fixing method to ensure that the sound insulation board will not move or fall off under the action of vibration. As a preferred embodiment of the present invention, a screw rod 21 is movably inserted into a first screw hole mechanism 19 at one end of the first mounting slot 15 and a second screw hole mechanism 20 at the same end of the second mounting slot 16. Nuts 22 are connected to both ends of the screw rod 21, and the nuts 22 are capable of securing the screw rod 21 between the first mounting slot 15 and the second mounting slot 16. Specifically, the screw rod 21 is a long screw rod 21, with both ends inserted into the first screw hole mechanism 19 and the second screw hole mechanism 20 on the same side, respectively, to connect the two mounting slots. Nuts 22 are provided at both ends of the screw rod 21 to secure the screw rod 21 and prevent it from sliding or falling out of the mounting slots. The screw rod 21 is secured between the two mounting slots by the nuts 22, providing a secure connection for the sound insulation board mechanism. The use of the nuts 22 prevents the screw rod 21 from loosening during use, ensuring the stability of the sound insulation board. The design of the screw rod 21 and the nut 22 allows for quick installation and removal of the sound insulation board mechanism, facilitating maintenance and replacement. By sharing the screw rod 21, the number of required components is reduced, making the structure more compact.

[0051] More preferably, a hoisting mechanism 23 is provided on the top of the sound insulation board mechanism. The hoisting mechanism 23 is provided on the top of the sound insulation board mechanism for hoisting and fixing the sound insulation board. The hoisting mechanism 23 makes the hoisting of the sound insulation board simple and quick, reducing the need for manual handling. Through the hoisting mechanism 23, the sound insulation board can be easily removed from the installation slot for easy inspection and maintenance.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention. It should be noted that the structures and components illustrated in the accompanying drawings are not necessarily drawn to scale, and that descriptions of known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the present invention.
