Description

Technical Field

[0001] This utility model belongs to the field of pipeline backfilling technology, specifically a hydraulic plate vibration compaction device for pipeline backfilling modification. Background Technology

[0002] Pipeline backfilling refers to filling the gaps around pipelines during the construction of drainage, water supply, gas, and communication pipelines. This process serves to achieve functions such as drainage, waterproofing, support, and insulation. To ensure soil compaction, a hydraulic plate vibratory compaction device for pipeline backfilling modification is used to compact the soil, stabilize the foundation around the pipeline, and ensure the uniformity and density of the backfill.

[0003] A search revealed Chinese patent application number 202022620066.4, which discloses a novel hydraulic plate vibratory compactor for pipeline backfill modification. The compactor consists of a hydraulic plate vibratory compactor, a steel plate, and an outer casing. The hydraulic plate vibratory compactor is a hydraulic type. The steel plate is located at the bottom of the hydraulic plate vibratory compactor. The steel plate is a modified version of the original thick steel plate with curved corners, replaced with a straight steel plate structure. A 6cm wide and 2cm thick outer casing is fitted onto the end of the improved straight steel plate and riveted to it with a rivet gun. Using existing hydraulic plate vibratory compactors, this new type achieves a backfill thickness of 20cm and a compaction degree of not less than 0.95 in 3 seconds. The modified hydraulic plate vibratory compactor achieves a backfill thickness of 30cm and a compaction degree of not less than 0.95 in 4 seconds.

[0004] The aforementioned patents still have the following shortcomings:

[0005] 1. The defect of easily generating dust: During the road construction process, the device needs to beat the surface soil for a long time, which will generate dust, reduce air quality, make the air turbid, and make the urban environment dirty and messy, affecting the overall image of the city and the quality of life of residents.

[0006] 2. The bottom is easily damaged. Due to the complex and varied working environment of the device, especially when working on hard ground or ground containing a lot of stones, the bottom of the device will be severely worn, affecting the service life of the device.

[0007] Therefore, there is an urgent need for a hydraulic plate vibration compaction device for pipeline backfilling and modification to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, this utility model provides a hydraulic plate vibration compaction device for pipeline backfilling modification, including a base plate 1, a replacement structure 6, a hydraulic motor 3, a lower connecting seat 2, a fixing frame 11, and a dustproof structure 7.

[0029] Replacement structure 6 is located at the bottom of base plate 1 to prevent base plate 1 from being worn.

[0030] The hydraulic motor 3 is installed on the top of the base plate 1, and an eccentric wheel box 10 is installed on one side of the hydraulic motor 3. The other side of the hydraulic motor 3 is connected to the oil pressure line 4. The output end of the hydraulic motor 3 rotates to drive the eccentric wheel inside the eccentric wheel box 10 to rotate.

[0031] The lower connecting seat 2 is fixed on both sides of the top of the base plate 1, and the top of the lower connecting seat 2 is equipped with a shock absorber 5. The top of the shock absorber 5 is fixed with the upper connecting seat 12. The shock absorber 5 is used for shock absorption.

[0032] The fixing bracket 11 is fixed to the top of the upper connecting seat 12, and the top of the fixing bracket 11 is fixed with the mounting seat 9. The connecting shaft 8 is inserted into the top of the mounting seat 9. The connecting shaft 8 is disassembled and the mounting seat 9 is installed.

[0033] The dustproof structure 7 is installed on the outside of the fixed frame 11. The dustproof structure 7 includes a nozzle 704 that is detachably installed on the outside of the fixed frame 11, a fixed frame 701 fixed on one side of the nozzle 704, a dustproof net 706 sleeved on the bottom of the fixed frame 701, and a spray assembly set on the inner wall of the fixed frame 701.

[0034] Specifically, the spray assembly includes a water supply pipe 702 fixed to the inner wall of the fixed frame 701, a connector 703 connected to the top of the water supply pipe 702, and a nozzle 704 installed at the bottom of the water supply pipe 702. By connecting the connector 703 to the tap water pipeline, water is introduced into the interior of the water supply pipe 702 and sprayed out by the nozzle 704 to wet the soil at the bottom of the base plate 1 and the surrounding air, thereby achieving the purpose of dust suppression.

[0035] Furthermore, several sets of nozzles 704 are installed at the bottom end of the water supply pipe 702, and the several sets of nozzles 704 are distributed at equal intervals at the bottom end of the water supply pipe 702. The range of water spraying is expanded by multiple sets of nozzles 704, and the spraying is made more uniform.

[0036] Furthermore, a connecting rod 705 is bolted to the outside of the fixing frame 11. The connecting rod 705 and the fixing frame 701 are welded together to form an integrated structure, which facilitates the installation and removal of the dustproof structure 7 according to construction needs.

[0037] It is worth noting that the replacement structure 6 includes a mounting groove 603 fixed to the bottom of the base plate 1, a fixing bolt 601 inserted inside the wear-resistant steel plate 605, a baffle 602 sleeved on the outside of the wear-resistant steel plate 605, a mounting groove 603 opened inside the baffle 602 and slidably connected to the wear-resistant steel plate 605, and a mounting block 604 fixed to the bottom of the baffle 602. The baffle 602 and the mounting block 604 prevent structural wear and damage to the base plate 1. By rotating and removing the fixing bolt 601, the baffle 602 is then pushed to separate from the wear-resistant steel plate 605, and the baffle 602 and the mounting block 604 are disassembled and replaced.

[0038] It is worth noting that the fixing bolt 601 extends through the base plate 1 into the interior of the wear-resistant steel plate 605, and the mounting block 604 is made of high manganese steel. The high manganese steel mounting block 604 has excellent hardness and durability and a long service life.

Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0040] Working principle: In use, the mounting base 9 is first fixed by disassembling and assembling the connecting shaft 8. The hydraulic motor 3 is then started via the oil pressure line 4. The output of the hydraulic motor 3 rotates the eccentric wheel inside the eccentric wheel box 10. The rotation of the eccentric wheel vibrates the ground through the base plate 1. During this vibration, the shock absorber 5 dampens the vibration. The fixing frame 701 and the dustproof net 706 shield the dust and splashes generated by the base plate 1. Water enters the water supply pipe 702 through the connector 703 and is sprayed out through the nozzle 704, wetting the soil at the bottom of the base plate 1 and the surrounding air. This completes the operation of the device. The air dust suppression function facilitates the handling of dust generated during the operation of the device, reducing the generation and spread of dust, protecting the working environment of the device, and preventing the splashing of gravel, thus enhancing the functionality of the device. The baffle 602 and the mounting block 604 prevent structural wear and damage to the base plate 1. By rotating and removing the fixing bolts 601, the baffle 602 and the wear-resistant steel plate 605 are separated, and the baffle 602 and the mounting block 604 can be disassembled and replaced. This realizes the easy maintenance function of the device, facilitates the protection of damaged parts at the bottom of the device, reduces the wear of the base plate 1, and extends the service life of the device.
