[0034] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.
[0035] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
[0040] In related technologies, during the pipe laying construction process, the foundation pit 01 is excavated first, then the pipe 02 is installed in the foundation pit 01, and then backfilling and laying the pipe is carried out. Before laying the pipe, the backfill soil on both sides and below the pipe 02 needs to be compacted or compacted to ensure that the density of the backfill soil meets the design requirements, prevent settlement, ensure the safe operation of the pipe 02, and extend its service life. The two sides of the pipe 02 are the pipe armpits, where the working space is narrow. The compaction or compaction of the armpit backfill soil 03 is usually done manually, which is labor-intensive. In addition, the slope of the foundation pit 01 of the pipe 02 is usually not protected, and the stability is poor. It is prone to instability and collapse when exposed to heavy rain or seismic waves, which can cause injury to the workers. Therefore, the technical solution of this application was developed. The following is a combination of... Figures 1 to 5 To elaborate.
[0041] Example 1
[0042] like Figures 1 to 5 As shown, the pipe axle corner backfilling and compaction equipment of this utility model includes a vehicle body 1. On the same side of the vehicle body 1, a vibratory compaction device 2 and a ball rolling compaction device 3 are detachably connected from front to back. The rear of the vehicle body 1 is connected to a base compaction device 4.
[0043] like Figure 1 and Figure 2As shown, the vibratory compaction device 2 includes a vibrator and a compaction plate 24. The vibrator includes a first hydraulic telescopic rod 21, a connecting seat 22, and a return spring 23. The first hydraulic telescopic rod 21 is connected to the vehicle body 1 and includes a cylinder and a rod. The rod can extend or retract relative to the cylinder. The compaction plate 24 is connected to the movable end of the rod. The connecting seat 22 is connected to the rod. The two ends of the return spring 23 are respectively connected to the connecting seat 22 and the end of the cylinder. The driving direction is parallel to the driving direction of the first hydraulic telescopic rod 21. When the first hydraulic telescopic rod 21 is loaded, it drives the pressing plate 24 to press against the axle corner fill 03, flattening the axle corner fill 03. Then the first hydraulic telescopic rod 21 is unloaded, and the return spring 23 drives the pressing plate 24 away from the axle corner fill 03, thereby repeatedly realizing the reciprocating vibration of the pressing plate 24. Thus, when the vehicle body 1 travels beside the pipeline 02 in the pit 01, the axle corner fill 03 set along one side of the pipeline 02 can be flattened continuously.
[0044] The above describes one specific structural form of the vibrator. Of course, other existing structural forms of the vibrator can also be used to achieve the reciprocating vibration of the compaction plate 24, which will not be elaborated here.
[0045] In an optional embodiment, the pressure plate 24 includes a steel plate and a rubber plate. The steel plate is connected to the end of the first hydraulic telescopic rod 21, and the rubber plate is bolted to the steel plate. The rubber plate and the first hydraulic telescopic rod 21 are located on opposite sides of the steel plate.
[0046] like Figure 3 and Figure 4 As shown, the ball compaction device 3 includes a second hydraulic telescopic rod 31, a frame 32, a first rotating shaft 33, and a ball 34. The second hydraulic telescopic rod 31 is connected to the vehicle body 1, and its movable end is connected to the frame 32. The first rotating shaft 33 is mounted on the frame 32 and passes through the ball 34. The ball 34 rotates around the first rotating shaft 33, and its rotation path is set along the length of the axle fill 03. The ball 34 is used to compact the axle fill 03. Preferably, the ball 34 is a solid steel ball, which has a larger moment of inertia and a better compaction effect on the axle fill 03.
[0047] In an optional embodiment, the rolling ball 34 is flattened on both sides of the first rotating shaft 33 to facilitate the setting and connection of the frame 32 and to facilitate the rolling ball compaction device 3 to operate in confined spaces.
[0048] In an alternative implementation, the rolling ball 34 can be replaced with a roller knot structure.
[0049] like Figure 1 , Figure 3 and Figure 5 As shown, the base compaction device 4 includes a roller, a second rotating shaft 41, and a lifting component 42. The second rotating shaft 41 passes through the roller, and the roller rotates around the second rotating shaft 41. The second rotating shaft 41 is connected to the vehicle body 1 through the lifting component 42. The lifting component 42 includes a suspension assembly, which applies downward pressure to the second rotating shaft 41, thereby applying downward pressure to the roller, which facilitates the roller's compaction of the bottom of the pit 01. The lifting component 42 can lift the roller off the ground. Preferably, the roller is a solid steel roller or a steel-clad concrete roller, which has a larger moment of inertia and provides better compaction of the bottom of the pit 01.
[0050] like Figure 1 , Figure 3 and Figure 5 As shown, the vehicle body 1 includes wheels 11, a cab 12, a hydraulic station 13, and a storage compartment. The hydraulic station 13 is connected to the first hydraulic telescopic rod 21 and the second hydraulic telescopic rod 31 via hydraulic pipelines. The cab 12 is equipped with a control panel, which is communicatively connected to the first hydraulic telescopic rod 21, the second hydraulic telescopic rod 31, and the hydraulic station 13.
[0051] When not in operation, the vibratory compaction device 2 and the ball rolling compaction device 3 can be removed from the vehicle body 1 and placed in the storage compartment. The lifting component 42 lifts the roller off the ground, and the vehicle body 1 can drive normally.
[0052] The pipeline axle backfilling and compaction equipment described in this embodiment uses a vehicle 1 to travel beside the pipeline 02 in the foundation pit 01. During the journey, the vibrator drives the compaction plate 24 to reciprocate and flatten the axle backfill 03, performing a first compaction. Then, the roller 34 compacts the axle backfill 03, completing a second compaction. Both the compaction plate 24 and the roller 34 can accommodate operations in confined spaces. Simultaneously, the base compaction device 4 compacts the bottom of the foundation pit 01 during the journey, thus eliminating the need to divide the compaction of the foundation pit 01 backfill into two processes. This mechanical approach greatly improves work efficiency, reduces labor intensity and safety risks. The pipeline axle backfilling and compaction equipment has a simple structure, high efficiency, and good results.
[0053] 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.
