Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to a foundation compaction device for road construction. Background Technology

[0002] In existing road paving technology, before laying asphalt or cement, it is necessary to lay subgrade soil to improve the load-bearing capacity of the road foundation. In the current subgrade soil laying process, the subgrade soil is still transported to the road by transport vehicles, the piled subgrade soil is leveled by bulldozers, and the subgrade soil is compacted by road rollers. However, the road rollers are too large and cannot compact the foundation of small roads, so the foundation needs to be compacted manually, which is labor-intensive, the compaction effect is not good, and a lot of dust is generated during the compaction process, which affects the surrounding environment.

[0003] To address the technical problems mentioned in the background section, prior art, patent document CN109183565A, discloses an edge foundation compaction device for road construction, comprising a base plate, a first bearing seat, a first rotating shaft, a first pulley, a pressure roller, a T-shaped rod, a first spring, a pressure plate, a vertical rod, a second bearing seat, a second rotating shaft, a second pulley, a triangular cam, a first flat belt, a support plate, a third rotating shaft, a drive motor, a double-groove pulley, a second flat belt, and a handle. A through hole is opened on the right side of the base plate, and the first bearing seat is installed on the bottom right side of the base plate. When the drive motor starts, water is discharged into the outlet pipe, and then the water in the outlet pipe is discharged into the hose. The hose discharges the water into the perforated pipe, and the perforated pipe sprays the water out. The water sprayed out sprays onto the pressure roller to prevent dust from appearing. In this way, the water can be sprayed evenly on the pressure roller, which better prevents dust from appearing. However, existing compaction devices are not convenient for adjusting the compaction intensity when compacting the roadbed. On the other hand, it is not convenient to achieve pre-scraping and multi-directional leveling of the roadbed in conjunction with the compaction operation. Based on this, the present invention provides a foundation compaction device for road construction to solve the technical problems mentioned in the background art. Summary of the Invention

[0017] 2.

By adjusting the pressure intensity, the compaction strength of this compaction device on the foundation can be quickly adjusted. During operation, the positive and negative spiral scrapers are used to perform bidirectional reciprocating motion on the protruding parts of the foundation. The leveling process, achieved through bidirectional reciprocating leveling, pre-levels the roadbed to be compacted. After pre-leveling, roller a initially flattens the leveled roadbed. Subsequently, the vibrating platform moves back and forth within a set stroke to compact the roadbed in the vertical direction. After the vibrating platform compacts the roadbed in the vertical direction, the bottom surface of the leveling seat remains in close contact with the roadbed. Under the action of the reverse linkage component, the two leveling seats move back and forth left and right within a set stroke, thereby achieving reciprocating leveling of the roadbed in the horizontal direction. The roadbed, after being leveled in the horizontal direction, is then compacted by roller b. Attached Figure Description

An eccentric block 13 is slidably connected to the inner wall of the adjustment groove 12.

[0035] A transmission solenoid 14 is rotatably connected to the circumferential side of the main spindle 3. The circumferential side of the transmission solenoid 14 is rotatably connected to the frame 1. A transmission ring 15 is rotatably connected to the circumferential side of the transmission solenoid 14. A guide post a16 is fixedly installed on the surface of the frame 1, which is parallel to the transmission solenoid 14. The circumferential side of the guide post a16 is slidably connected to the transmission ring 15.

[0036] A driven ring 17 is rotatably connected to the circumferential side of the transmission ring 15. A first connecting rod 18 is hinged between the driven ring 17 and the opposite surface of the eccentric block 13. A second connecting rod 19 is hinged between the eccentric block 13 and the opposite surface of the reciprocating frame 4.

[0037] When the rotating frame 11 is driven by the main shaft 3, the eccentric block 13 and the second connecting rod 19 are set so that when the rotating frame 11 rotates, the reciprocating frame 4 can reciprocate within the set stroke.

[0038] When it is necessary to change the reciprocating stroke of the reciprocating frame 4, the position of the transmission ring 15 on the transmission screw tube 14 can be quickly changed by rotating the transmission screw tube 14. By changing the position of the transmission ring 15 on the transmission screw tube 14, the position of the eccentric block 13 on the adjusting groove 12 can be quickly changed.

[0039] By switching the position of the eccentric block 13 on the adjustment groove 12, the reciprocating stroke of the reciprocating frame 4 when the rotating frame 11 rotates can be quickly adjusted.

The peripheral side of the two scraper shafts 23 is fixedly mounted with a positive spiral scraper blade 25 and a negative spiral scraper blade 26, respectively. The pressure roller a24 is located between the negative spiral scraper blade 26 and the vibrating platform 6.

[0045] By setting up the positive spiral scraper 25 and the negative spiral scraper 26, the protruding part in the foundation is scraped and leveled in both directions. Through the realization of the bidirectional reciprocating scraping effect, the roadbed to be compacted is pre-leveled.

[0046] The dynamic counterweight components include a liquid storage tank 27 fixed to the surface of the frame 1 and a set of regularly distributed counterweight cylinders 28 fixed to the top surface of the vibrating platform 6.

A guide tube is fixedly installed at the axial position of each counterweight cylinder 28. The top end of the guide tube is fixedly connected to the multi-port hose. A level gauge 29 is fixedly installed inside one counterweight cylinder 28. A microcontroller electrically connected to the level gauge 29 is fixedly installed on the side of the frame 1.

[0047] The weight of the counterweight on the vibration platform 6 can be dynamically adjusted by setting up dynamic counterweight components.

[0048] By adjusting the weight of the counterweight on the vibration platform 6, the pressure applied to the roadbed by the vibration platform 6 within a single displacement stroke can be quickly adjusted.

[0049] It also includes a rotating arm 31 located on the side of the frame 1 and rotatably connected to the frame 1 via a rotating shaft. An auxiliary motor 32 fixedly connected to the rotating shaft is fixedly installed on the surface of the frame 1, and a roadbed baffle 33 is fixedly installed on the surface of the rotating arm 31.

[0050] When not in use, the roadbed baffle 33 is set upward and retracted under the drive of the auxiliary motor 32;

[0051] In use, the roadbed baffle 33 is set vertically downwards and blocks the roadbed from the side of the roadbed edge. By blocking, the compacted soil is prevented from falling irregularly outwards from the roadbed edge during the roadbed compaction process.

[0052] The reverse linkage components include a fixed shaft 34 rotatably connected to the inner wall of the reciprocating frame 4 and a moving shaft 39 rotatably connected to the inner wall of the pressure frame 7. Both the fixed shaft 34 and the coupling 22 have linkage bevel teeth fixedly installed at their tail ends, and the two linkage bevel teeth mesh with each other. The moving shaft 39 has a shaft groove with a top opening that is slidably connected to the fixed shaft 34. A half gear 35 is fixedly installed at the bottom end of the moving shaft 39. Two guide posts b36 are fixedly installed on the bottom surface of the pressure frame 7.

The peripheral surfaces of the two guide posts b36 are slidably connected to the two driven tooth plates 37 respectively. A second spring 38 is sleeved on the peripheral surfaces of the two guide posts b36.

[0053] Half gear 35 is disposed between two driven gear plates 37. The reciprocating direction of the smoothing seat 10 is parallel to the axis of the pressure roller a24. A baffle plate 30 is fixedly disposed on one side of the smoothing seat 10 adjacent to the vibrating platform 6. A transition arc surface is fixedly disposed at the connection between the baffle plate 30 and the smoothing seat 10. The cross-sections of the shaft groove and the fixed shaft 34 are both regular polygons.

[0054] The tail of the frame 1 is rotatably connected to a pressure roller b40, the radius of which is three times the radius of the pressure roller a24.

[0055] In use, this device is carried by an external traction device or load device;

[0056] When not in use, the roadbed baffle 33 is set upward and retracted under the drive of the auxiliary motor 32;

[0057] In use, the roadbed baffle 33 is set vertically downward and blocks the roadbed from the side of the roadbed edge. By blocking, the compacted soil is prevented from falling irregularly outward from the roadbed edge during the roadbed compaction process.

[0058] During operation, based on the compaction strength requirements of the roadbed, the position of the eccentric block 13 on the adjustment groove 12 is adjusted by driving the transmission screw tube 14. By switching the position of the eccentric block 13 on the adjustment groove 12, the reciprocating motion stroke of the reciprocating frame 4 when the rotating frame 11 rotates can be quickly adjusted.

[0059] By adjusting the reciprocating stroke of the reciprocating frame 4, the pressure intensity of the reciprocating frame 4 on the vibrating platform 6 can be quickly adjusted. By adjusting the pressure intensity, the compaction intensity of the compaction device on the foundation can be quickly adjusted. During operation, the positive spiral scraper 25 and the negative spiral scraper 26 are used to reciprocate and level the protruding parts in the foundation in both directions. By achieving the effect of reciprocating and leveling in both directions, the roadbed to be compacted is pre-leveled. After the roadbed is pre-leveled, the pressure roller a24 performs initial flattening on the leveled roadbed. Subsequently, the vibrating platform 6 moves back and forth within the set stroke to reciprocate and compact the roadbed in the up and down direction. After the vibrating platform 6 reciprocates and compacts the roadbed in the up and down direction, the bottom surface of the smoothing seat 10 remains in close contact with the roadbed. Under the action of the reverse linkage component, the two smoothing seats 10 move back and forth left and right within the set stroke, thereby achieving reciprocating and leveling of the roadbed in the left and right direction. The roadbed after reciprocating and leveling in the left and right directions is then compacted by the pressure roller b40.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
