Description

Technical Field

[0001] This utility model belongs to the field of road surface anti-settlement technology, specifically relating to a road surface settlement prevention device for municipal pipeline trench construction. Background Technology

[0002] Road surface settlement is a common and challenging problem during the construction of municipal pipeline trenches. The construction of municipal pipeline trenches requires the excavation and operation of underground space, which inevitably disturbs the soil structure around the trench.

[0003] In existing technologies, most municipal pipeline trenches require anti-settlement treatment of the road surface after construction. This is usually done using simple backfilling and compaction methods. During construction, the excavated soil is simply backfilled into the trench, and then conventional compaction equipment (rammers) is used to compact only the surface. Due to the long compaction distance and high manual labor intensity, the compaction work in each area cannot be sustained for a long time. This results in the inability to thoroughly compact the soil particles, leaving a large number of pores inside the soil. The friction and interlocking force between soil particles are insufficient, resulting in the soil being in a loose state overall. The compaction effect is poor, and during subsequent use, factors such as vehicle traffic and natural settlement cannot effectively prevent road surface settlement caused by loose soil.

[0023] In one possible implementation, the fixing frame includes:

[0024] The top plate is horizontally positioned and fixedly connected to the vehicle body;

[0052] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0053] Please refer to the following: Figures 1 to 3 The present invention describes a road surface settlement prevention device for municipal pipeline trench construction. The device includes a vehicle body 10, a fixing frame 20, and a compaction component 30. The vehicle body 10 has two parallel and spaced-apart walking sections, forming an installation space between them. The fixing frame 20 is fixed to the vehicle body 10 and located within the installation space, forming a connecting space. The compaction component 30 is located within this connecting space and slides along the direction of travel of the vehicle body 10, slidably connected to the fixing frame 20. The bottom of the compaction component 30 has a compaction section that can contact the ground. As the vehicle body 10 moves, the compaction component 30 compacts the ground through this compaction section.

[0054] The road settlement prevention device for municipal pipeline trench construction provided in this embodiment, compared with the prior art, has two traveling parts on the vehicle body 10 that can respectively correspond to both sides of the trench, thereby ensuring that the compaction component 30 on the fixing frame 20 corresponds to the trench. The fixing frame 20 can ensure a fixed connection with the vehicle body 10, thereby ensuring that the compaction component 30 is fixed on the vehicle body 10. The compaction part in the compaction component 30 can compact the bottom surface in the downward direction. At the same time, in conjunction with the vehicle body 10, it can free up manpower, facilitate the adjustment of the dwell time, and thus ensure the compaction depth. This allows soil particles to overcome the friction and interlocking forces between each other, generate relative displacement, fill the pores in the soil, reduce porosity, increase soil density, effectively reduce road settlement caused by soil loosening in the later stage, and ensure the compaction effect. The tamping component 30 is slidably connected to the fixed frame 20 along the traveling direction of the walking part, which can ensure that the friction force of the tamping part in the traveling direction is offset as the vehicle body 10 moves, thereby ensuring the tamping effect and ensuring the stable operation of the tamping part.

[0055] In some embodiments, the aforementioned tamping component 30 may employ, for example... Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3 The compaction component 30 includes an outer sliding frame 31, an inner sliding frame 33, a base plate 35, and a drive structure 36. The outer sliding frame 31 has a through cavity, and the bottom end of the outer sliding frame 31 has a notch communicating with the through cavity. Along the traveling direction of the vehicle body 10, the outer sliding frame 31 has an outer elastic sliding structure 32 on each side that can be slidably connected to the fixing frame 20. The outer elastic sliding structure 32 enables the outer sliding frame 31 to have a continuous tendency to move towards the center of the connecting space. The inner sliding frame 33 is located in the through cavity. Along the vertical direction, the inner sliding frame 33 has an inner elastic sliding structure 34 on each side that can be slidably connected to the outer sliding frame 31. The inner elastic sliding structure 34 enables the inner sliding frame 33 to have a continuous tendency to move towards the center of the through cavity. The base plate 35 is horizontally set below the outer sliding frame 31 and is fixedly connected to the inner sliding frame 33 through a vertical plate passing through the notch. The base plate 35 is the compaction part. The drive structure 36 can drive the inner sliding frame 33 to reciprocate.

[0056] The outer sliding frame 31 is slidably mounted on the fixed frame 20 along the traveling direction of the traveling part, which can ensure compensation for the base plate 35 in this direction. The base plate 35 moves vertically back and forth relative to the outer sliding frame 31. However, as the vehicle body 10 moves, the base plate 35 will generate a certain amount of friction with the ground. The sliding connection of the outer sliding frame 31 can effectively offset this friction. At the same time, the outer elastic sliding structures 32 provided on both sides of the outer sliding frame 31 can ensure self-adjustment of the outer sliding frame 31, so that the outer sliding frame 31 can return to the center of the connecting space no matter how it moves.

[0057] The inner sliding frame 33 is slidably disposed in the through cavity along the vertical direction, which can ensure that the base plate 35 moves back and forth in the vertical direction relative to the outer sliding frame 31, thereby realizing the continuous patting of the base plate 35 on the ground. The inner elastic sliding structure 34 connected to the upper and lower sides of the inner sliding frame 33 can ensure the self-adjustment of the inner sliding frame 33, so that the inner sliding frame 33 can return to the center of the through cavity no matter how it moves.

[0058] In this embodiment, the drive structure 36 is set on the inner sliding frame 33, which can drive the inner sliding frame 33 to shake. The base plate 35, which is fixedly connected to the inner sliding frame 33, can move in the plane in the direction of travel and the vertical direction of the vehicle body 10 with the support of the outer sliding frame 31 and the inner sliding frame 33, thereby ensuring the compaction effect of the backfill soil in the trench.

[0059] In some embodiments, the external elastic sliding structure 32 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 Each external elastic sliding structure 32 includes an external sliding post 321 and an external spring 322. Multiple external sliding posts 321 are provided, spaced apart vertically. One end of each external sliding post 321 is fixedly connected to the external sliding frame 31, and the other end extends out through the external sliding frame 31 along the travel direction of the vehicle body 10. Multiple external springs 322 are provided, each corresponding to one of the external sliding posts 321. Each external spring 322 is sleeved on its corresponding external sliding post 321, with one end abutting against the external sliding frame 31 and the other end abutting against the inner wall of the connecting space.

[0060] Each outer sliding post 321 is fitted with an outer spring 322. Each outer spring 322 can ensure that the outer sliding frame 31 bounces, thereby ensuring that the outer sliding frame 31 continues to move towards the center position of the connecting space. Its structure is simple and easy to manufacture.

[0061] It should be noted that each outer sliding post 321 extends a certain distance from the fixing frame 20 to prevent the outer sliding post 321 from disengaging from the sliding connection with the fixing frame 20.

[0062] In some embodiments, the aforementioned internal elastic sliding structure 34 may employ, as shown in the following example: Figure 3 The structure shown. See also Figure 3 Each internal elastic sliding structure 34 includes an inner sliding post and an inner spring 342. Multiple inner sliding posts are provided, spaced apart along the travel direction of the vehicle body 10. One end of each inner sliding post is fixedly connected to the inner sliding frame 33, and the other end extends vertically through the inner sliding frame 33. Multiple inner springs 342 are provided, each corresponding to one of the inner sliding posts. Each inner spring 342 is sleeved on its corresponding inner sliding post, with one end abutting against the inner sliding frame 33 and the other end abutting against the inner wall of the through cavity.

[0063] Each inner sliding column is fitted with an inner spring 342. Each inner spring 342 ensures that the inner sliding frame 33 bounces, thereby ensuring that the inner sliding frame 33 continues to move towards the center position of the connecting space. Its structure is simple and easy to manufacture.

[0064] Among them, the internal elastic sliding structures 34 located at the bottom are respectively located on both sides of the opening.

[0065] It should be noted that each inner sliding post extends a certain distance from the fixing frame 20 to prevent the inner sliding post from detaching from the sliding connection with the outer sliding frame 31.

[0066] In some embodiments, the driving structure 36 described above may adopt the following... Figure 4 The structure shown. See also Figure 4 The drive structure 36 includes a dual-head motor 361 and an eccentric rotating block 362. The dual-head motor 361 is fixed in the inner sliding frame 33 and has two coaxially arranged power output ends. The axis of the power output ends is arranged along the interval direction of the two traveling parts. Two eccentric rotating blocks 362 are provided, and the two eccentric rotating blocks 362 are respectively fixedly connected to the two power output ends.

[0067] The dual-head motor 361 can provide two power outputs simultaneously, which in turn drive two eccentric rotating blocks 362 to rotate. The two eccentric rotating blocks 362 increase the shaking effect. The center of gravity of each eccentric rotating block 362 is spaced apart from the axis of the power output, so that the inner sliding frame 33 vibrates during the rotation of the eccentric rotating block 362, and the base plate 35 moves back and forth in the vertical direction to continuously pat and compact the ground.

[0068] In some embodiments, the aforementioned fixing bracket 20 may be adopted as follows: Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3 The mounting bracket 20 includes a top plate 21 and vertical plates 22. The top plate 21 is horizontally arranged and fixedly connected to the vehicle body 10. There are two vertical plates 22, which are spaced apart along the travel direction of the vehicle body 10, and a connecting space is formed between the two vertical plates 22.

[0069] The top plate 21 and the two vertical plates 22 form a U-shaped structure, which facilitates the enclosure of the compaction component 30. At the same time, the two vertical plates 22 can ensure the sliding connection of each outer sliding column 321.

[0070] In some embodiments, the vehicle body 10 may adopt the following... Figure 1 , Figure 2 , Figure 5 and Figure 6The structure shown. See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The vehicle body 10 includes a frame 11, slides 12, tracks 13, and adjustment components 14. The slides 12 are located on both sides of the frame 11 and are slidably connected to the vehicle body 10, forming an installation space between the two slides 12. There are two tracks 13, which are respectively mounted on the two slides 12. The tracks 13 are the running gear. The adjustment components 14 are mounted on the frame 11 and connected to the two slides 12, enabling the two slides 12 to move relative to each other or in opposite directions.

[0071] The width of the trenches varies, such as large pipeline trenches and small trenches in alleys or residential areas. In this case, the distance between the two sliding blocks 12 can be adjusted by adjusting the component 14, thereby adjusting the distance between the two traveling tracks 13. This ensures that the vehicle body 10 can adapt to trenches of different widths, improving applicability and versatility, and reducing the time required for replacement or adjustment due to incompatibility with the trench.

[0072] The slide block 12 may be provided with multiple slide rods 15, and the frame 11 is provided with multiple slide sleeves 16 that correspond one-to-one with each of the slide rods 15. The slide cavity in each slide sleeve 16 allows the corresponding slide rod 15 to be slidably connected.

[0073] In some embodiments, the adjustment component 14 described above may employ, for example... Figure 4 and Figure 5 The structure shown. See also Figure 4 and Figure 5 The adjustment assembly 14 includes a rotating shaft 141, a gear 142, a rack 143, a connecting rod 144, and a rotation adjustment structure 145. The rotating shaft 141 is rotatably mounted on the frame 11, with its axis arranged vertically. The gear 142 is coaxially connected to the rotating shaft 141 and is located at the bottom of the frame 11. There are two racks 143, each arranged along the interval direction of the slide 12 and at intervals along the travel direction of the track 13. Each rack 143 meshes with the gear 142. There are two connecting rods 144, each connected to the slide 12 and respectively connected to the two racks 143. The rotation adjustment structure 145 is mounted on the frame 11 and connected to the rotating shaft 141, enabling the rotating shaft 141 to rotate.

[0074] The rotating adjustment structure 145 drives the rotating shaft 141 to rotate, which in turn drives the gear 142 on the rotating shaft 141 to move the two racks 143 relative to each other or in opposite directions. Through the two connecting rods 144, the two slides 12 can be moved relative to each other or in opposite directions. Its adjustment is convenient and controllable, which can effectively improve its versatility and adaptability.

[0075] In some embodiments, the rotation adjustment structure 145 described above can be adopted as follows: Figure 5 The structure shown. See also Figure 5 The rotation adjustment structure 145 includes a worm gear 1451, a worm 1452, and a driver 1453. The worm gear 1451 is located on the upper part of the frame 11 and is coaxially connected to the shaft 141. The worm 1452 is rotatably mounted on the frame 11 and meshes with the worm gear 1451. The driver 1453 is fixed on the frame 11 and is poweredly connected to the worm 1452.

[0076] The worm gear 1451 and worm 1452 are designed with a self-locking function, which can ensure that the rotating shaft 141 can be locked, thereby ensuring the locking of the distance between the two slides 12. The driver 1453 can ensure that the worm 1452 is rotated, thereby realizing convenient adjustment of the rotating shaft 141.

[0077] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
