Description

Technical Field

[0001] This invention relates to the field of compaction equipment technology, and in particular to a roadbed compaction equipment. Background Technology

[0002] A tamping device is a mechanical device used to compact loose soil by impact. It typically consists of a tamping machine body and a tamping head connected to it. The tamping head applies impact force to the ground through its reciprocating motion, thereby improving the density and bearing capacity of the soil. It is widely used in engineering scenarios such as roadbeds and foundations.

[0003] In actual use, the repeated impact of the ramming head on the soil will cause surface soil particles to be thrown up and form a large amount of dust. At the same time, due to the concentrated release of impact force, there will also be obvious structural noise and airborne noise. This dust and noise not only affect the working environment, but also easily have an adverse impact on the surrounding area. Therefore, it is usually necessary to control the dust and noise during the operation of the ramming machine.

[0004] Existing methods for controlling dust and noise from rammers mostly involve external water pipes, manual water spraying, or additional soundproofing baffles. These methods lack mechanical linkage with the rammer itself, resulting in asynchronous water spraying and rammering, and deviation between the spraying area and the rammering point. This increases the complexity of construction and makes it difficult to effectively suppress dust and impact noise at the moment of rammering, thus making the dust and noise control effect unstable. Summary of the Invention

[0005] In view of the problem in the above or existing technology of how to achieve dust reduction and noise reduction control in sync with the compaction action of the roadbed tamping device without adding an independent power and control system, the present invention is proposed.

This allows for the simultaneous suppression of construction dust and noise without relying on additional power or control systems. The pump is driven by the movement of the tamping head, so that the atomizing nozzle sprays water mist into the through hole and the tamping area at the moment of tamping, thereby forming a moist and isolation layer at the source of dust generation and effectively suppressing the spread of dust. The tamping head drives the baffle to lock the traveling wheels, keeping the equipment stable during the tamping phase and sealing the gap between the traveling wheels and the ground to reduce noise leakage channels. The rotating frame driven by the shaft causes the fur pad and rubber plate to rub against each other to generate static electricity. This static electricity, combined with the sound-absorbing cotton and sound-deflecting block, adsorbs, absorbs and disperses the dust particles and sound waves inside the enclosure, thereby further reducing the intensity of dust suspension and noise transmission. All functions are directly driven by the reciprocating motion of the tamping head, which makes the spray intensity, locking degree and rotational friction state automatically change with the tamping rhythm, achieving adaptive adjustment.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0031] Reference Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a roadbed compaction device, which includes a compaction component 1, a dust prevention component 2, a positioning component 3, a transmission component 4, and a noise reduction component 5, so as to achieve comprehensive suppression of dust and noise during the roadbed compaction process.

[0032] Specifically, the compaction component 1 includes a compactor body 11, a compactor head 12 located at the end of the compactor body 11, a cover 13 located on the outer periphery of the compactor head 12, and a through hole 14 opened on the end face of the cover 13. The compactor body 11 is used to provide power to the compactor head 12, the compactor head 12 is used to periodically impact the roadbed, and the cover 13 is used to form a closed working space around the compactor head 12.

[0033] The dustproof component 2 includes a base 21 disposed on the outside of the housing 13, an atomizing nozzle 24 disposed at the port of the through hole 14, and a pump 27 disposed inside the base 21. The atomizing nozzle 24 is used to atomize the liquid and spray it toward the ground, and the pump 27 is used to pressurize the liquid under the drive of the tamping action.

[0034] The positioning component 3 includes a baffle 33 located at the bottom of the cover 13. The baffle 33 is used to limit the movement of the whole machine during the tamping process, thereby ensuring the stability of the overall position of the device during tamping.

[0035] The transmission assembly 4 includes a shaft 44 that penetrates the outer wall of the housing 13, an extrusion block 45 that is disposed at the end of the shaft 44, and a vertical rod 41 disposed at the top of the ramming head 12. The vertical rod 41 moves up and down with the ramming head 12 and is converted into a lateral drive for the shaft 44. The shaft 44 is used to transmit the driving force to other components.

[0036] The noise reduction component 5 includes a rubber plate 51 disposed on the inner wall of the housing 13, a rotating frame 54 disposed on the inner surface of the rubber plate 51, and a fur pad 56 disposed on the rotating frame 54. The fur pad 56 can absorb some sound waves due to its own material, and the surface of the rubber plate 51 disperses sound waves. Together, they can suppress the propagation of noise. The rotating frame 54 is used to support the fur pad 56 and rotates under the drive of the shaft 44. Friction on the rubber plate 51 generates static electricity to attract floating dust.

[0037] The base 21 and the atomizing nozzle 24 are interconnected. The shaft 44 drives the pump 27 to supply liquid to the atomizing nozzle 24 for spraying through the reciprocating motion of the ramming head 12. The rotating frame 54 is set on the outer surface of the shaft 44, and the shaft 44 drives the rotating frame 54 to rotate the fur pad 56.

[0038] During use, the rammer body 11 drives the rammer head 12 to move up and down reciprocally to compact the roadbed. During the movement, the rammer head 12 pushes the drive block 43 through the pulley 42 at the top of the upright 41. The drive block 43 can rotate to convert sliding friction into rolling friction to reduce resistance. Since the outer end face of the drive block 43 is inclined, the drive block 43 moves laterally in a straight line under the push of the drive block 43. The drive block 43 pushes the extrusion block 45 through the shaft 44. The extrusion block 45 pushes the roller 276 and guide wheel 36 through the inclined surface of the side wall. Roller 276 pushes piston 275 through push rod 274. The movement of piston 275 inside hydraulic tank 273 creates air pressure. One-way valve 272 at the lower end of water supply tank 271 opens under pressure. Liquid inside water supply tank 271 is sent to valve seat 23 through connecting pipe 25 and sprayed out from atomizing nozzle 24 towards the ground. First, water mist covers through hole 14 to prevent dust from spreading. At the same time, it wets the subsequent roadbed to prevent dust generation. Second, water mist coverage can isolate sound waves to a certain extent and suppress noise levels. The guide wheel 36 pushes the baffle 33 through the connecting rod 35. The baffle 33 descends and contacts the traveling wheel 32 to generate frictional resistance, locking the traveling wheel 32 to prevent it from rotating, ensuring that the entire device will not shift during the tamping process. At the same time, the descending baffle 33 blocks the ground gap caused by the traveling wheel 32, and the baffle 33 isolates sound waves to a certain extent, suppressing the propagation of noise. During the movement, the shaft 44 forces the limiting slider 55 of the rotating frame 54 to slide along the thread 46, thereby causing the rotating frame 54 to rotate circumferentially along the annular groove 57. The rotating frame 54 drives the fur pad 56 to rub against the rubber plate 51. The rubber plate 51 generates static electricity under the friction of the fur pad 56, which can adsorb floating particulate impurities within the coverage area of ​​the cover 13, accelerate the settling of dust and avoid the spread of dust. The fur pad 56 and sound-absorbing cotton 58 can absorb some sound waves due to their own materials, and the sound-dispersing block 52 on the surface of the rubber plate 51 disperses sound waves, which together can suppress the propagation of noise.

[0039] In summary, by simultaneously converting the tamping motion of the tamping head 12 into three actions—spraying liquid supply, bottom locking, and internal rotational friction of the casing 13—the roadbed compaction is carried out while simultaneously suppressing dust diffusion and noise propagation. The water mist curtain formed by the spray first forms a physical isolation at the through hole 14 and wets the tamping area to reduce dust generation. The descent of the baffle 33 blocks the noise propagation path and improves equipment stability by eliminating the gap between the traveling wheel 32 and the ground. The static electricity generated by the friction between the fur pad 56 and the rubber plate 51, as well as the sound absorption properties of the material itself, further treat the suspended particles and sound waves inside the casing 13. Thus, adaptive dust and noise reduction based on the tamping rhythm can be achieved without relying on external electrical systems. Example 2

[0040] Reference Figures 1 to 8 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides structural optimization of the compaction component 1 and the dustproof component 2 of the roadbed compaction device.

[0041] Specifically, the ramming machine body 11 is installed on the top of the cover 13, the ramming head 12 is located inside the cover 13 and connected to the output end of the ramming head 12, and a handrail 15 is provided on the top outer wall of the ramming head 12 to facilitate the construction personnel to guide and control the device.

[0042] A valve seat 23 is provided on the outer wall of the through hole 14. The outer end face of the valve seat 23 is an inclined surface facing the ground. Multiple atomizing nozzles 24 are arranged in an array on the outer end face of the valve seat 23. A connecting pipe 25 is provided between the pump pressure component 27 and the valve seat 23. The atomizing nozzles 24 and the valve seat 23 are interconnected. The atomizing nozzles 24 expand the spray coverage area and form a uniform water curtain.

[0043] The pump component 27 includes a water supply tank 271 longitudinally opened on the top surface of the base 21, a hydraulic tank 273 opened on the middle side wall of the water supply tank 271, and a one-way valve 272 set at the upper and lower ends of the water supply tank 271. A water tank 22 connected to the water supply tank 271 is set on the top of the base 21. A connecting pipe 25 is connected to the bottom end of the water supply tank 271. The one-way valve 272 realizes the one-way flow control of the liquid. The water tank 22 allows the external liquid to be continuously replenished to the water supply tank 271. The connecting pipe 25 ensures that the pressurized liquid can be delivered to the atomizing nozzle 24.

[0044] The base 21 has a movable groove 26 on one side surface of the cover 13. The extrusion block 45 is located inside the movable groove 26. The inner wall of the movable groove 26 is provided with a guide cylinder 47. The end face of the extrusion block 45 is provided with a positioning rod 49. The positioning rod 49 is located inside the guide cylinder 47 and slides axially with each other. The positioning rod 49 and the guide cylinder 47 are engaged in the circumferential direction. A strong spring 48 is provided between the end face of the extrusion block 45 and the inner wall of the movable groove 26. The extrusion block 45 is located inside the movable groove 26 to receive the thrust from the shaft 44. The strong spring 48 enables the extrusion block 45 to automatically reset after the external force disappears.

[0045] Hydraulic groove 273 is connected to movable groove 26. A piston 275 is installed inside hydraulic groove 273. A push rod 274 is installed on the outer wall of piston 275. The other end of push rod 274 is located in movable groove 26 and is equipped with roller 276. A return spring 277 is installed between roller 276 and inner wall of movable groove 26. Return spring 277 is wrapped around the outer surface of push rod 274. Roller 276 is in contact with the side of extrusion block 45. Each side of extrusion block 45 is inclined. Roller 276 causes push rod 274 to generate low-resistance rolling contact under the action of the inclined surface of extrusion block 45. Return spring 277 causes roller 276 to automatically return to its position after unloading.

[0046] The rest of the structure is the same as in Example 1.

[0047] During use, the rammer body 11 drives the rammer head 12 to periodically impact the roadbed inside the casing 13. The movement of the rammer head 12 is converted into a lateral thrust on the shaft 44 through the upright 41, pulley 42 and drive block 43, causing the shaft 44 to generate reciprocating linear motion with each rammer. This motion is transmitted to the roller 276 and guide wheel 36 by the inclined surface of the extrusion block 45. The roller 276 pushes the push rod 274 to drive the piston 275 to move in the hydraulic groove 273. With the cooperation of the water supply groove 271 and the one-way valve 272, the liquid in the water tank 22 is continuously sent into the connecting pipe 25 and finally sprayed out by the atomizing nozzle 24 to form a uniform water mist. The guide wheel 36 drives the baffle 33 to press down on the traveling wheel 32 through the connecting rod 35 to achieve the locking function, so that the equipment does not move during the rammering stage. Since the pump pressure component 27 and the extrusion block 45 adopt an inclined surface and rolling structure, the spray pressure can change with the rammering amplitude.

[0048] In summary, Example 2 makes the liquid pressurization process more stable and controllable, and keeps the spray volume of the atomizing nozzle 24 highly consistent with the actual tamping state of the tamping head 12. This provides a denser water mist to suppress severe dust during heavy tamping and reduces unnecessary water consumption during light tamping. At the same time, the linkage locking of the baffle 33 still ensures that the equipment does not slip during tamping, so that the spray coverage area always maintains a corresponding relationship with the tamping point. Example 3

[0049] Reference Figures 1 to 8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides structural optimization of the positioning component 3, transmission component 4 and noise reduction component 5 of the roadbed compaction device to improve overall stability and noise control capability.

[0050] Specifically, the bottom surface of the base 21 is provided with a square groove 31 to accommodate the baffle 33. The inner wall of the bottom end of the square groove 31 is horizontally arranged with traveling wheels 32. The baffle 33 is located above the traveling wheels 32 and has a corresponding notch. The inner wall of the movable groove 26 is provided with a sleeve hole 34 that communicates with the square groove 31. The top of the baffle 33 is provided with a connecting rod 35 that penetrates the sleeve hole 34. The end of the connecting rod 35 is provided with a guide wheel 36 that fits against the side wall of the extrusion block 45. A support spring 37 is provided between the guide wheel 36 and the inner wall of the movable groove 26. The support spring 37 is wrapped around the outer surface of the connecting rod 35. The traveling wheels 32 enable the device to move in a non-impact state, and the support spring 37 keeps the baffle 33 in a raised state when there is no extrusion force.

[0051] The inner wall of the cover 13 has a mounting hole 53. The rubber plate 51 is located at the inner port of the mounting hole 53. The outer surface of the rubber plate 51 is arrayed with sound deflecting blocks 52. The inner circumferential surface of the mounting hole 53 has an annular groove 57. The rotating frame 54 is located inside the mounting hole 53. The outer edge of the rotating frame 54 is slidably located inside the annular groove 57. The end face of the fur pad 56 is in contact with the surface of the rubber plate 51. The inner wall of the cover 13 is hollow and is provided with sound-absorbing cotton 58. The sound deflecting blocks 52 disperse the sound wave reflection path, and the sound-absorbing cotton 58 absorbs and attenuates the sound waves.

[0052] The rotating frame 54 has a circular hole in the center for the shaft 44 to pass through. A limit slider 55 is provided on the inner wall of the circular hole. A threaded slide 46 is provided on the outer surface of the shaft 44. The limit slider 55 is located inside the threaded slide 46 and slides in contact with it, so as to convert the linear displacement of the shaft 44 into the circular motion of the rotating frame 54.

[0053] One end of the shaft 44, located inside the housing 13, is mounted on the drive block 43. A pulley 42 is rotatably mounted on the top of the upright 41, and the drive block 43 is located on top of the pulley 42. The outer end face of the drive block 43 is inclined, and the pulley 42 and the outer end face of the drive block 43 are in contact. The drive block 43 enables the power from the ramming head 12 to be transmitted to the shaft 44, and the pulley 42 reduces friction. The rest of the structure is the same as in Example 2.

[0054] During use, when the device needs to be moved, the traveling wheels 32 are in a free state to facilitate the construction personnel to push the equipment to the designated position. After the rammer body 11 is started, the up and down movement of the rammer head 12 is transmitted to the shaft 44 through the upright 41, pulley 42 and drive block 43, causing the shaft 44 to push the extrusion block 45 to move. The extrusion block 45 drives the baffle 33 downward into the square groove 31 through the guide wheel 36 and connecting rod 35 and presses the traveling wheels 32, so that friction is formed between the traveling wheels 32 and the ground. The locking mechanism prevents the equipment from shifting due to reaction force during the compaction phase. Simultaneously, the shaft 44 drives the dustproof component 2 to work in conjunction with the rotating frame 54, causing the atomizing nozzle 24 to spray water mist to cover the through hole 14 and the compaction area during compaction. Meanwhile, the rotating frame 54 drives the fur pad 56 to rotate and rub against the surface of the rubber plate 51 to generate static electricity. This, in conjunction with the sound-absorbing cotton 58 and the sound-shifting block 52, treats the dust particles and sound waves inside the cover 13, thereby maintaining a low level of dust and noise while compacting the roadbed.

[0055] In summary, the device is mobile while automatically locking itself during the compaction phase. Combined with the multi-layered acoustic and electrostatic treatment structure inside the housing 13, the spray, water mist isolation, mechanical limiting, and sound wave absorption achieve a highly synergistic effect. The movement of the tamping head 12 is the sole power input to drive all auxiliary functions, thereby achieving high stability, low dust, and low noise operation during the roadbed compaction process without increasing control complexity.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
