Description

Technical Field

[0001] This utility model relates to the field of roadbed construction technology, and in particular to a high-efficiency compaction device for roadbed engineering. Background Technology

[0002] Roadbed engineering is the foundation of road construction. It bears the traffic load transmitted from the road surface and is an important support for the entire road structure. During the road construction process, the quality of the roadbed directly affects the service life of the road and driving safety. In order to ensure that the roadbed has sufficient strength, stability and uniformity, the roadbed material needs to be compacted.

[0003] A compaction device is a mechanical device that compacts loose materials such as soil and gravel using mechanical force. Its working principle is to use the gravity or impact force of the hammer to repeatedly strike the roadbed surface, causing the loose material particles to squeeze and fill each other, thereby reducing porosity and increasing density. Common compaction devices include frog tampers and dynamic compaction machines, which are widely used in foundation treatment of road and building projects.

[0004] The existing high-efficiency compaction equipment for roadbed engineering has the following shortcomings:

[0005] First, most tamping equipment has a fixed lifting height and impact force, which cannot be flexibly adjusted according to different construction scenarios. For example, when dealing with roadbeds of different depths and soil types, the tamping height cannot be easily changed, which may lead to over-compaction in shallow soft soil areas and difficulty in achieving the ideal compaction depth in deep hard soil areas, affecting construction efficiency and quality. Second, traditional tamping hammer structures lack effective buffering and adjustment mechanisms. The strong recoil force generated after the tamping hammer impacts the roadbed not only aggravates the wear of equipment components and shortens the equipment's service life, but also cannot adjust the buffering effect according to different soil requirements. At the same time, the fixed buffering design either provides insufficient buffering, resulting in excessive equipment vibration, or excessive buffering, consuming too much tamping hammer energy and reducing the compaction effect, making it difficult to achieve a balance between buffering and compaction performance. Utility Model Content

[0006] This utility model mainly provides a high-efficiency compaction device for roadbed engineering that can flexibly adjust the compaction height and force, and has efficient buffering and performance adjustment functions.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency compaction device for roadbed engineering, comprising a movable push frame, a drive assembly rigidly connected to the top of the movable push frame, a connecting sliding hole with vertical conduction opened in the middle of the movable push frame, a tamping hammer assembly slidably connected to the inner surface of the connecting sliding hole, and a lifting slide plate fixedly connected to the top of the tamping hammer assembly.

[0008] The drive assembly includes two support plates, which are fixedly connected to the top left and right sides of the movable push frame, respectively. A drive motor is fixedly connected to the opposite side of each of the two support plates. The output shaft of the drive motor passes through to the other side of the support plate and is fixedly connected to a rotating disk. A connecting slide column is slidably connected to the opposite side of the two rotating disks. A connecting slide groove that passes through the middle of the lifting slide plate is provided. The outer surface of the connecting slide column is slidably connected to the inner surface of the connecting slide groove.

[0009] Preferably, a sliding groove is provided at the bottom of the opposite surfaces of the two rotating disks, and a threaded column is rotatably connected to the middle of the sliding groove. The bottom end of the threaded column extends through to the bottom of the rotating disk and is fixedly connected to a knob.

[0010] Preferably, the outer surface of the threaded column is threadedly connected to a threaded sliding plate, the outer surface of the threaded sliding plate is slidably connected to the inner surface of the sliding groove, and the left and right ends of the connecting sliding column are respectively fixedly connected to the opposite surfaces of the two threaded sliding plates.

[0011] Preferably, the tamping hammer assembly includes a sliding column, which is fixedly connected to the bottom of the lifting slide plate and its outer surface is slidably connected to the inner surface of the connecting sliding hole. A sliding tamping block is slidably sleeved at the bottom end of the outer surface of the sliding column. A connecting groove is provided at the bottom end of the sliding column, and a plurality of buffer springs are provided inside the connecting groove. The bottom end of the buffer springs is fixedly connected to the top of the sliding tamping block.

[0012] Preferably, the sliding column has limit sliders fixedly connected to both the left and right sides below the inner surface of the sliding column, and the sliding block has limit grooves on both the left and right sides of the outer surface of the sliding block, with the limit sliders slidably connected to the inner surface of the limit grooves.

[0013] Preferably, a sliding pressure plate is fixedly connected to the top of the buffer spring, and the front and rear ends of the sliding pressure plate extend to the lower front and rear sides of the outer surface of the sliding column, respectively. The front and rear ends of the sliding pressure plate are threaded with adjusting bolts that extend vertically, and the two adjusting bolts are rotatably connected to the lower front and rear sides of the outer surface of the sliding column, respectively.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, the drive motor drives the rotating disk to rotate, and the connecting slide column slides in the connecting groove, thereby driving the lifting slide plate and the tamping hammer assembly to reciprocate to achieve the compaction operation. At the same time, rotating the knob causes the threaded column to rotate, which drives the threaded slide plate to slide in the sliding groove, thereby changing the position of the connecting slide column and achieving precise adjustment of the height of the tamping hammer assembly. This structural design can flexibly adjust the falling height and impact force of the tamping hammer according to different roadbed construction needs. When dealing with shallow soft soil, the height of the tamping hammer is reduced to avoid over-compaction; when dealing with deep hard soil, the height of the tamping hammer is increased to ensure the compaction depth, effectively improving construction efficiency and quality, and solving the problem of the non-adjustable impact parameters of existing equipment.

[0016] 2. In this utility model, when the sliding tamping block rebounds upwards after impacting the roadbed, the buffer spring is compressed and deformed, absorbing part of the kinetic energy of the sliding tamping block and providing buffering, reducing the impact of the recoil force on the equipment components, and extending the service life of the equipment. By turning the adjusting bolt, the position of the sliding pressure plate can be changed, thereby adjusting the compression degree of the buffer spring and realizing the adjustment of the spring stiffness. When dealing with harder soil, the spring stiffness is increased to reduce energy loss and ensure the impact force; when dealing with softer soil, the spring stiffness is reduced to ensure the buffering effect. Thus, under different working conditions, the tamping performance of the sliding tamping block can be maintained to the greatest extent while ensuring the buffering function, overcoming the defect of traditional tamping hammers that are difficult to balance buffering and tamping.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a high-efficiency compaction device for roadbed engineering, including a movable push frame 1, a drive assembly 2 rigidly connected to the top of the movable push frame 1, a connecting sliding hole 11 with vertical conduction opened in the middle of the movable push frame 1, a tamping hammer assembly 4 slidably connected to the inner surface of the connecting sliding hole 11, a lifting slide plate 3 fixedly connected to the top of the tamping hammer assembly 4, the drive assembly 2 including two support plates 21, the two support plates 21 respectively fixedly connected to the left and right sides of the top of the movable push frame 1, a drive motor 22 fixedly connected to the opposite sides of the two support plates 21, the output shaft of the drive motor 22 passing through to the other side of the support plate 21 and fixedly connected to a rotating disk 23, a connecting sliding column 24 slidably connected to the opposite sides of the two rotating disks 23, a connecting sliding groove 31 with horizontal conduction opened in the middle of the lifting slide plate 3, and the outer surface of the connecting sliding column 24 slidably connected to the inner surface of the connecting sliding groove 31.

[0025] like Figure 3 As shown, each of the two rotating disks 23 has a sliding groove 25 at its bottom opposite surface. A threaded post 26 is rotatably connected to the middle of the sliding groove 25. The bottom end of the threaded post 26 extends through to the bottom of the rotating disk 23 and is fixedly connected to a knob 28. When the knob 28 is rotated, the threaded post 26 rotates accordingly. Since the threaded sliding plate 27 is threadedly connected to the threaded post 26 and can only slide within the sliding groove 25, the rotation of the threaded post 26 will cause the threaded sliding plate 27 to move up and down along the axis of the threaded post 26 within the sliding groove 25, thereby changing the vertical position of the connecting sliding post 24. The beneficial effect of this design is that the starting height of the tamping hammer assembly 4 can be precisely adjusted according to the soil quality and compaction requirements of different roadbeds, thereby changing the falling height and impact force of the tamping hammer, greatly improving the adaptability of the equipment to different construction scenarios.

[0026] like Figure 3As shown, the outer surface of the threaded column 26 is threadedly connected to the threaded slide plate 27. The outer surface of the threaded slide plate 27 is slidably connected to the inner surface of the sliding groove 25. The left and right ends of the connecting column 24 are fixedly connected to the opposite surfaces of the two threaded slide plates 27 respectively. This makes the position adjustment of the connecting column 24 more stable and reliable. The threaded drive has a self-locking function. After the position of the connecting column 24 is adjusted, the threaded slide plate 27 will not slide easily, ensuring the high stability of the tamping hammer assembly 4 during operation and avoiding the impact of position changes on the compaction effect.

[0027] like Figure 4 As shown, the tamping hammer assembly 4 includes a sliding column 41, which is fixedly connected to the bottom of the lifting slide plate 3 and its outer surface is slidably connected to the inner surface of the connecting sliding hole 11. A sliding tamping block 42 is slidably sleeved at the bottom end of the outer surface of the sliding column 41. A connecting groove 45 is provided at the bottom end of the sliding column 41. Several buffer springs 46 are provided inside the connecting groove 45. The bottom end of the buffer spring 46 is fixedly connected to the top of the sliding tamping block 42. Here, when the sliding tamping block 42 tamps the roadbed, it will be subjected to the upward reaction force of the roadbed. At this time, the buffer spring 46 is compressed and deformed, converting part of the kinetic energy of the sliding tamping block 42 into elastic potential energy, effectively buffering the recoil force, reducing the impact of the recoil force on the sliding column 41, the lifting slide plate 3, and the drive assembly 2, reducing the wear of the equipment components, and extending the overall service life of the equipment.

[0028] like Figure 4 As shown, the sliding column 41 has a limit slider 43 fixedly connected to the lower left and right sides of its inner surface, and the sliding tamping block 42 has a limit groove 44 opened on the left and right sides of its outer surface. The limit slider 43 is slidably connected to the inner surface of the limit groove 44. Here, the limit structure can ensure that the sliding tamping block 42 slides stably on the sliding column 41, prevent the sliding tamping block 42 from shifting or rotating during the up and down movement, ensure the accuracy and stability of the tamping, and also avoid additional torsional damage to the buffer spring 46 caused by the shaking of the sliding tamping block 42.

[0029] like Figure 4As shown, a sliding pressure plate 47 is fixedly connected to the top of the buffer spring 46. The front and rear ends of the sliding pressure plate 47 extend to the lower front and rear sides of the outer surface of the sliding column 41, respectively. Both ends of the sliding pressure plate 47 are threaded with adjusting bolts 48 that extend vertically. The two adjusting bolts 48 are rotatably connected to the lower front and rear sides of the outer surface of the sliding column 41, respectively. Here, by turning the adjusting bolts 48, the sliding pressure plate 47 can be moved up and down on the sliding column 41, thereby changing the compression degree of the buffer spring 46. When dealing with harder soil, the adjusting bolts 48 are turned upward to increase the stiffness of the buffer spring 46, so that the buffer spring 46 can minimize energy loss when absorbing the recoil force and ensure that the sliding tamping block 42 has sufficient tamping force. When dealing with softer soil, the adjusting bolts 48 are turned downward to reduce the stiffness of the buffer spring 46, enhance the buffering effect, and prevent the equipment from vibrating violently due to excessive recoil force.

[0030] The usage method and working principle of this device are as follows: Before use, adjust the threaded column 26 by turning the knob 28 according to the soil conditions and compaction requirements of the roadbed, thereby moving the threaded slide plate 27 to adjust the position of the connecting slide column 24 and determine the starting height of the hammer assembly 4 in order to set an appropriate tamping force. At the same time, adjust the position of the sliding pressure plate 47 by turning the adjusting bolt 48 to change the stiffness of the buffer spring 46, so that the equipment can adapt to different construction conditions.

[0031] In use, the mobile pusher 1 is pushed to move the equipment to the subgrade area to be compacted. The drive motor 22 is started, which drives the rotating disk 23 to rotate. The connecting slide column 24 slides in the connecting slide groove 31 of the lifting slide plate 3 under the drive of the rotating disk 23. This causes the lifting slide plate 3 and the hammer assembly 4 to move up and down along the connecting slide hole 11 of the mobile pusher 1. When the sliding tamping block 42 falls to contact the subgrade, it tamps the subgrade, causing the subgrade material particles to squeeze and fill each other, thus improving the subgrade density. During the upward rebound of the sliding tamping block 42 after tamping the subgrade, the buffer spring 46 is compressed and deformed, absorbing part of the kinetic energy of the sliding tamping block 42 and reducing the impact of the recoil force on the equipment components. As the drive motor 22 continues to run, the hammer assembly 4 continuously performs up and down reciprocating compaction operations until the subgrade compaction work in this area is completed. Throughout the entire working process, the cooperation between the limiting slider 43 and the limiting slide groove 44 ensures the stable sliding of the sliding tamping block 42, ensuring the accuracy and stability of the compaction operation.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
