Description

Technical Field

[0001] The utility model relates to the technical field of compaction devices, in particular to a compaction device for a foundation pit of a long-distance pipeline structure. Background Art

[0002] At present, the construction of foundation pits for long-distance pipeline structures usually includes the following steps:

[0003] Foundation pit excavation: Use an excavator or other excavation equipment to dig a foundation pit along the pipeline laying path in preparation for the construction of the structure.

[0004] Foundation pit compaction: Use a compactor to compact the foundation pit to ensure that the soil at the bottom and sides of the pit is dense to avoid subsequent sinking.

[0005] Structure construction: Build structures such as piers and supports in the compacted foundation pit to support the pipelines.

[0006] Pipeline laying: After the construction of the structure is completed, the pipeline is laid on the structure to ensure the stability and safety of the pipeline.

[0007] Traditional compactors are typically fixed to the front of a vehicle frame and operated through it. This design limits the compactor's working range, restricting compaction to a narrow area in front of the frame. Due to the limited range of motion of the frame, the compactor cannot cover the entire excavation, particularly the center and corners, increasing construction complexity and time costs. Summary of the Invention

[0008] The technical problem to be solved by the utility model is that the working range of the compactor vertically fixed to the front end of the frame is limited, resulting in low construction efficiency and high cost.

[0009] In order to solve the above technical problems, the technical solution adopted by the utility model is: a long-distance pipeline structure foundation pit compaction device, including a compaction component with the top hinged to the movable end of the excavator arm, the compaction component includes a connecting head with the top hinged to the movable end of the excavator arm, a compaction hydraulic cylinder fixed in the connecting head and a lifting pipe axially slidingly sleeved on the bottom of the connecting head, the bottom end of the lifting pipe is parallelly connected to a force transmission rod, the bottom end of the force transmission rod is horizontally fixedly connected to a compaction plate, and the movable end of the compaction hydraulic cylinder is connected to the impact plate axially slidingly arranged at the bottom of the lifting pipe.

[0010] Preferably, the bottom end of the force transmission rod is sleeved with a connecting tube, and the bottom end of the connecting tube is fixedly connected to the top center of the tamping plate.

[0011] Preferably, a reinforcing plate is connected between the side wall of the connecting tube and the top surface of the tamping plate, and reinforcing plates are provided around the connecting tube.

[0012] Preferably, a frame plate is provided at the edge of the tamping plate.

[0013] Preferably, the impact plate is in a cross shape, and guide grooves are provided on the side walls of the hanging pipe, and the movable ends of the impact plates are vertically slidably arranged in the guide grooves.

[0014] Preferably, a rib plate is connected between the top surface of the impact plate and the output end of the compacting hydraulic cylinder, each end of the impact plate is arranged on the rib plate, and a notch for accommodating the rib plate is opened at the top of the guide groove.

[0015] Preferably, the top end of the force transmission rod is fixedly connected to a connecting plate, and the hanging pipe is fixed on the top of the connecting plate.

[0016] The utility model provides a tamping device for a foundation pit of a long-distance pipeline structure. By installing the tamping component on the movable end of the excavator arm, the excavator can place the tamping component inside the foundation pit from the outside of the foundation pit, and perform tamping construction on the inside of the foundation pit through the tamping component, thereby increasing the construction range of the excavator. It is unnecessary to use a crane to lift the frame into the foundation pit, thereby improving the efficiency of the foundation pit tamping construction and reducing the construction cost.

[0021] like Figure 1 and Figure 2 As shown, the utility model proposes a long-distance pipeline structure foundation pit compaction device, including a compaction component 2 with the top hinged to the movable end of the excavator arm 1, the compaction component 2 includes a connecting head 21 with the top hinged to the movable end of the excavator arm 1, a compaction hydraulic cylinder 29 fixed in the connecting head 21 and a lifting pipe 22 axially slidingly sleeved on the bottom of the connecting head 21, the bottom end of the lifting pipe 22 is parallelly connected to a force transmission rod 23, the bottom end of the force transmission rod 23 is horizontally fixedly connected to a compaction plate 25, and the movable end of the compaction hydraulic cylinder 29 is connected to an impact plate 27 axially slidingly arranged at the bottom of the lifting pipe 22.

[0022] When tamping the foundation pit, the tamping assembly 2 is placed in the foundation pit through the arm of the excavator 1. The movable end of the hydraulic cylinder on the arm is hinged to the end of the tamping assembly 2. By controlling the extension and contraction of the hydraulic cylinder, the tamping assembly 2 is adjusted to a vertical state.

[0023] After the tamping assembly 2 is placed, the movable end of the tamping hydraulic cylinder 29 is controlled to continuously extend and retract, driving the impact plate 27 to continuously move up and down, and impact the lifting pipe 22. The lifting pipe 22 impacts the tamping plate 25 through the force transmission rod 23 to achieve compaction of the inside of the foundation pit.

[0024] The hanging pipe 22 is sleeved on the connecting head 21 , and the impact plate 27 serves as a limiting structure and cooperates with the guide groove 28 to prevent the hanging pipe 22 from falling off the connecting head 21 .

[0025] like Figure 2 As shown, to improve the stability of the connection between the dowel rod 23 and the tamping plate 25, a connecting tube 24 is mounted on the bottom end of the dowel rod 23. The bottom end of the connecting tube 24 is fixedly connected to the top center of the tamping plate 25. The connecting tube 24 increases the connection area between the dowel rod 23 and the tamping plate 25, thereby improving stability.

[0026] like Figure 2 As shown, to further enhance the stability of the connection between the dowel rod 23 and the tamping plate 25, a reinforcing plate 26 is connected between the side wall of the connecting tube 24 and the top surface of the tamping plate 25. Reinforcing plates 26 are provided on all four sides of the connecting tube 24. These reinforcing plates 26 serve as connecting ribs and are distributed along the outer wall of the connecting tube 24. They not only enhance the stability of the connection between the dowel rod 23, but also serve as vertical plates connected to the top surface of the tamping plate 25, enhancing its strength.

[0027] like Figure 2 The edge of the tamping plate 25 is provided with a frame plate. The frame plate is provided so that the edge of the tamping plate 25 can be prevented from bending when the tamping plate 25 is tamping the foundation pit, thereby extending the service life of the tamping plate 25.

[0028] like Figure 1 and Figure 2 As shown in the figure, the impact plate 27 is cross-shaped, and the side walls of the hanging tube 22 are each provided with a guide groove 28. The movable end of the impact plate 27 slides vertically within the guide groove 28. The cooperation between the impact plate 27 and the guide groove 28 prevents the hanging tube 22 from falling off the bottom end of the connector 21. The cross-shaped impact plate 27 ensures that the lifting tube 22 is evenly stressed when it strikes the hanging tube 22.

[0029] like Figure 2As shown. A rib is connected between the top surface of the impact plate 27 and the output end of the compacting hydraulic cylinder 29. Each end of the impact plate 27 is seated on the rib. A notch is defined at the top of the guide groove 28 to accommodate the rib. When the excavator 1 moves, the rib on the top of the impact plate 27 engages with the notch at the top of the guide groove 28, supporting the lifting pipe 22 through the impact plate 27. The rib serves to increase the strength of the impact plate 27.

[0030] like Figure 2 As shown, in order to improve the strength of the bottom of the hanging pipe 22, the bottom of the hanging pipe 22 is supported by a connecting plate. The top of the force transmission rod 23 is fixedly connected with the connecting plate, and the hanging pipe 22 is fixed on the top of the connecting plate.
