Description

Technical Field

[0002] At present, in order to avoid uneven road surface or even collapse risks during pipeline trench backfilling, soil is usually compacted by machine. However, in most cases, the original soil or sand backfilled in the supporting corners below the pipeline is not solid. Later, the settlement of backfill soil and the passage of heavy vehicles can easily cause the pipeline to sink and bend. In addition, most of the existing compaction equipment is a single compactor that is manually held to compact the roadbed, and the corners at the bottom of the pipeline are difficult to compact, which consumes a lot of time and increases the labor intensity of the staff.

[0030] Reference Figures 1 to 5 An embodiment of the present application provides a municipal sewage pipe trench compacting machine, including a main frame 1, a movable cross frame assembly 2, a horizontal movable adjustment frame 3, a first compacting assembly 4 and a second compacting assembly 5.

[0031] Reference Figure 2 A rectangular chute 11 is provided at the bottom of the main frame 1. The movable cross frame assembly 2 is slidably connected in the rectangular chute 11. Specifically, a cross frame adjusting screw 12 is provided in the rectangular chute 11, and the left and right ends of the cross frame adjusting screw 12 are mounted on the main frame 1.

[0032] The movable horizontal frame assembly 2 includes a first movable horizontal frame 21 and a second movable horizontal frame 22, which are symmetrically arranged and in an eight-shaped shape. That is, the spacing between the upper ends of the first movable horizontal frame 21 and the second movable horizontal frame 22 is smaller than the spacing between the lower ends. The upper end nut parts of the first movable horizontal frame 21 and the second movable horizontal frame 22 are both connected to the horizontal frame adjusting screw 12, and the lower ends extend out of the rectangular slide 11.

The lower ends of the first movable horizontal frame 21 and the second movable horizontal frame 22 are both connected to rollers 23. Therefore, the first movable horizontal frame 21 and the second movable horizontal frame 22 can not only move along the extension direction of the pipeline groove, which is convenient for the movement of the tamping machine of the embodiment of the present application, but also can move left and right along the horizontal frame adjusting screw 12 to adjust the width to adapt to pipeline grooves of different widths.

[0033] Reference Figure 1 and Figure 3 , the horizontal movable adjustment frame 3 is connected to the front surface of the main frame 1 and is located in front of the rectangular slide groove 11. The horizontal movable adjustment frame 3 is in the shape of a rectangular plate, and two adjustment grooves 31 symmetrically arranged on the left and right are provided thereon.

Specifically, a tamping assembly adjustment screw 32 is provided in each adjustment groove 31, and the left and right ends of the two tamping assembly adjustment screws 32 are respectively mounted on the side walls of the corresponding adjustment groove 31.

[0034] The tamping assembly adjusting screw rod 32 is connected to the ball nut seat 6. The lower end of the ball nut seat 6 extends out of the adjusting slot 31 and is connected to the hydraulic press 7. The bottom of the hydraulic press 7 is connected to the first tamping assembly 4 or the second tamping assembly 5.

[0035] A driving motor (not shown) is provided in each adjusting slot 31, and the output end of the driving motor is connected to the tamping assembly adjusting screw 32 through a coupling (not shown). The driving motor can drive the corresponding tamping assembly adjusting screw 3 to rotate, thereby driving the ball nut seat 6, the hydraulic press 7, the first tamping assembly 4 or the second tamping assembly 5 to move left and right, thereby adjusting the position to be tamped by the tamping assembly.

[0036] Reference Figure 4 and Figure 5 The first tamping assembly 4 includes a semi-cylindrical base 41 and a first angle adjustment assembly 42 disposed on the upper portion thereof. The second tamping assembly 5 includes an arc-shaped base 51 and a second angle adjustment assembly 52 disposed on the upper portion thereof. The first angle adjustment assembly 42 can adjust the axial inclination angle of the semi-cylindrical base 41, and the second angle adjustment assembly 52 can adjust the axial inclination angle of the arc-shaped base 51.

[0037] The first angle adjustment assembly 42 includes a directional disk 421, an adjustment disk 422, a fixed angle disk 423, a fixing bolt 424 and a connecting shaft 425. The directional disk 421 and the adjustment disk 422 are both arranged in the horizontal direction. The upper end of the directional disk 421 is connected to the hydraulic press 7, and the lower end is rotatably connected to the adjustment disk 422. The bottom surface of the adjustment disk 422 is provided with a fixed angle disk mounting groove 426, and the side wall of the fixed angle disk mounting groove 426 is provided with a connecting hole 427. The fixed angle disk 423 is a semicircular disk, which is arranged in the vertical direction, and its upper end is inserted into the fixed angle disk mounting groove 426. The upper end of the fixed angle disk 423 is provided with a plurality of adjustment holes 428 equidistantly distributed along the circumferential direction, and the center of the lower end is provided with a hinge hole 429, and both sides are fixedly connected to the semi-cylindrical base 41 or the arc base 51. The fixing bolt 424 passes through the connecting hole 427 and one of the adjusting holes 428 to connect the adjusting disk 422 with the fixed angle disk 423 . The connecting shaft 425 is hinged in the hinge hole 429 , and its upper end is fixedly connected to the adjusting disk 422 via a connecting plate.

[0038] The structure of the second angle adjustment assembly 52 is the same as that of the first angle adjustment assembly 42 and will not be described in detail herein.

[0039] The semi-cylindrical base 41 adopts a metal mold. The arc base 51 includes a rectangular base body 511 and a recess 512 opened on the right side of the rectangular base body 511, and the recess 512 is a quarter cylinder. The semi-cylindrical base 41 can directly compact the original soil foundation into an arc shape, solving the problem of loose backfill soil under the pipeline and insufficient foundation support. The arc base 51 can be used to compact the backfill soil above the pipeline to protect the pipeline.

[0040] The working principle of the compacting tool in the embodiment of the present application is as follows:

[0041] The compacting machine in the embodiment of the present application is used for compacting the original soil foundation at the supporting angle below the sewage pipe and compacting the backfill soil. According to the different pipe diameters, a strong semi-cylindrical base 41 that can be quickly assembled and matches the pipe diameter is selected for installation, and then the driving motor in the left adjusting slot 31 is started. The driving motor drives the compacting assembly adjusting screw 32 to rotate, thereby driving the ball nut seat 6, the hydraulic press 7 and the first compacting assembly 4 to move, changing the compacting position, and compacting the original soil into an arc that matches the pipe.

[0042] After the pipeline is laid, backfill soil is buried, and the position of the second tamping assembly 5 on the right is adjusted to tamp the backfill soil covering the surface of the pipeline.

[0043] When it is necessary to compact the pipeline groove with a slope, the fixing bolt 424 can be removed first. At this time, the fixed angle disc 423 can rotate around the connecting shaft 425, and then the hydraulic press 7 is controlled to drive the semi-cylindrical base 41 to make it close to the bottom of the pipeline groove. Under the influence of the slope, the fixed angle disc 423 will rotate around the connecting shaft 425, and sliding will occur between the fixed angle disc 423 and the adjusting disc 422. The position of the adjusting hole 428 on the fixed angle disc 423 also changes. When the axial inclination angle of the semi-cylindrical base 41 is stable, the fixing bolt 424 is installed to reconnect the fixed angle disc 423 with the fixed angle disc 423. At this time, the semi-cylindrical base 41 can be stabilized in a preset inclined position. Then, the second compacting assembly 5 can be driven by the hydraulic press 7 to compact the angled slope, and when compaction work is required for slopes in different directions, the adjusting disc 422 can be rotated relative to the directional disc 421 to perform compaction work.

[0044] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
