Description

Technical Field

[0001] This utility model relates to a symmetrical backfilling device for pipeline construction, belonging to the technical field of municipal engineering and water conservancy engineering equipment. Background Technology

[0002] Pipeline laying is a common construction project in municipal and water conservancy engineering. One common method involves excavating trenches, burying the pipeline within them, and then backfilling and compacting the fill. Currently, pipeline backfilling is commonly done manually or mechanically. Manual backfilling is prone to asymmetrical filling on both sides of the pipeline, leading to pipeline displacement. Mechanical backfilling equipment cannot achieve synchronous symmetrical filling on both sides, also easily causing pipeline displacement. Furthermore, current mechanical backfilling equipment is not suitable for complex terrain with steep slopes. Additionally, current backfilling methods suffer from uneven compaction of the backfill layer, with measured density differences reaching up to 200 kg / m³. Summary of the Invention

[0003] The purpose of this invention is to provide a symmetrical backfilling device for pipeline construction. This device can achieve synchronous symmetrical material feeding from both sides, avoiding pipeline displacement and ensuring uniform compaction of the backfill layer.

[0004] The technical solution of this utility model is as follows: A symmetrical backfilling device for pipeline construction includes a crossbeam, a column vertically arranged in the middle of the crossbeam, a hopper at the top of the column, a screw feeder in the hopper, a diversion bin on each of the left and right sides of the bottom of the hopper, and a feeding pipe connected to each diversion bin. A transverse movement mechanism is provided on the crossbeam, and two mounting seats are symmetrically arranged on the left and right sides of the transverse movement mechanism. One side of each mounting seat is connected to the lower end of a feeding pipe, and a vertical hydraulic cylinder is installed on the other side of the mounting seat. A vibrating plate is connected to the top of the push rod of the vertical hydraulic cylinder. A longitudinal beam is provided at each end of the crossbeam, and a traveling wheel is provided at the bottom of the longitudinal beam. The traveling wheel is connected to a drive mechanism. Hydraulic cylinders are also provided at both ends of the longitudinal beam, and movable foot plates are provided at the bottom of the hydraulic cylinders.

[0005] In the aforementioned symmetrical backfilling device for pipeline construction, the feeding pipe is composed of multiple interconnected pipe sections, with the bottommost pipe section connected to a steel wire hose.

[0006] In the aforementioned symmetrical backfilling device for pipeline construction, laser rangefinders are installed at the bottom of the crossbeams on both sides of the column.

[0007] In the aforementioned symmetrical backfilling device for pipeline construction, a pressure sensor is installed on the vibrating plate.

[0008] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model, by setting a screw feeder on the hopper and symmetrically arranging two feeding pipes, allows the backfill material to be evenly distributed to the two side distribution hoppers via the screw feeder. The two feeding pipes ensure synchronous and symmetrical feeding on both sides of the pipeline, thus avoiding pipeline deviation caused by uneven feeding. When the device moves to the area requiring backfill compaction, the hydraulic cylinder drives the movable foot plate to push out and press against the ground, ensuring the stability of the device structure and thus adapting to complex terrain with large slopes. The compaction intensity is collected by a pressure sensor on the vibrating plate, and the compaction parameters are automatically adjusted based on the feedback. The control system displays parameters such as filler symmetry and compaction degree in real time, thereby ensuring uniform compaction of the backfill layer. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0013] An embodiment of this utility model: A symmetrical backfilling device for pipeline construction includes a crossbeam 16, a column 11 vertically arranged in the middle of the crossbeam 16, a hopper 7 arranged on the top of the column 11, a screw feeder 8 arranged in the hopper 7, a diversion bin connected to the left and right sides of the bottom of the hopper 7, and a feeding pipe 6 connected to each diversion bin. A transverse movement mechanism is arranged on the crossbeam 16, and two mounting seats 9 are symmetrically arranged on the left and right sides of the transverse movement mechanism. One side of each mounting seat 9 is connected to the lower end of a feeding pipe 6, and a vertical cylinder 10 is installed on the other side of the mounting seat 9. A vibrating plate 13 is connected to the top of the push rod of the vertical cylinder 10. A longitudinal beam 12 is arranged at each end of the crossbeam 16. A traveling wheel 14 is arranged at the bottom of the longitudinal beam 12. The traveling wheel 14 is connected to a drive mechanism 15. A hydraulic cylinder 3 is also arranged at both ends of the longitudinal beam 12. A movable foot plate 2 is arranged at the bottom of the hydraulic cylinder 3.

[0014] During use, the device of this utility model moves to the required backfilling and compaction area via the traveling wheels 14 under the action of the drive mechanism 15, and then stops moving. The hydraulic cylinder 3 pushes the movable foot plate 2 out to press against the ground. Other equipment puts the mixed filler into the silo 7. Under the action of the screw feeder 8, the filler is lowered and evenly distributed to the two side distribution bins. The filler in the distribution bins is then discharged through the feeding pipe 6. At the same time, the push rod of the vertical cylinder 10 extends and drives the vibrating plate 13 downward. The vibrating plate 13 contacts the filler, and the filler is compacted under the continuous vibration of the vibrating plate 13. At the same time, the transverse movement mechanism can drive the mounting seat 9 to move back and forth along the direction of the crossbeam 16 to realize the transverse movement of the vibrating plate 13. The transverse movement mechanism can adopt common hydraulic cylinders, screw drive mechanisms, synchronous belt drives, etc. When using hydraulic cylinders, a hydraulic cylinder can be set at each end of the crossbeam 16. The mounting seat 9 is installed on the push rod of the hydraulic cylinder, and the mounting seat 9 can be moved back and forth by the hydraulic cylinder. After the backfilling and compaction of one area is completed, the vertical cylinder 10 drives the vibrating plate 13 to move upward, and then the hydraulic cylinder 3 drives the movable foot plate 2 to move upward. The device can then move to the next area under the action of the traveling wheels 14.

[0015] The feeding pipe 6 is composed of multiple pipe sections 5 connected to each other. The feeding pipe 6 can move back and forth with the mounting base 9. The bottommost pipe section 5 is connected to the steel wire hose 4. The worker holds the steel wire hose 4 and feeds the filling material to the area that needs filling.

[0016] Laser rangefinders 17 are installed at the bottom of the crossbeams 16 on both sides of the column 11 to determine the axis of the pipe 1. Since the width of the trench for installing the pipe 1 is almost uniform, once the axis of the pipe 1 is determined, the distance from each side of the pipe 1 to the installation trench can also be determined, thus confirming the width of the compaction by the vibrating plate 13. Under the control system, the left and right lateral movement distance of the lateral movement mechanism can be controlled to ensure that the filler on both sides of the pipe 1 is compacted, while avoiding contact between the vibrating plate 13 and the pipe 1 and the installation trench. At the same time, once the axis of the pipe 1 is determined, the path of the traveling wheels 14 can be controlled by the control system to ensure that the column 11 is always above the axis of the pipe 1.

[0017] A pressure sensor is installed on the vibrating plate 13. The pressure sensor collects the compaction strength of the filling material by the vibrating plate 13 and feeds the compaction strength back to the control system of the device. The control system can automatically adjust the compaction parameters accordingly.
