Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a roadbed settlement repair device based on road engineering. Background Technology

[0002] Road surface subsidence is a typical road defect, and its formation mechanism involves multiple factors. Most existing repair processes employ a step-by-step approach. First, the subsided pavement needs to be trimmed and excavated. Then, the treated pits are filled. Finally, a road roller is used to compact the surface. This multi-step process, with time intervals between operations, not only prolongs the treatment time but also easily leads to cold joints at the interface between old and new materials, thus affecting the final repair bond. Furthermore, in some small-scale road surface repairs, the equipment is often too large, making it difficult to concentrate on the subsidence area and resulting in poor treatment outcomes. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a roadbed settlement repair device based on road engineering, which has the advantages of small-scale roadbed settlement repair, high degree of automation, and support for multi-step synchronous operation.

[0004] In a first aspect, the present invention provides a roadbed subsidence repair device based on road engineering, comprising a support frame, a feed pipe, a lifting plate, a scraping component, and a telescopic base. The support frame is movably mounted above the roadbed subsidence point. The lifting plate is located above the support frame and a telescopic component is provided between the two. The moving end of the telescopic component is provided with a limiting post. The lifting plate is movably fitted onto the limiting post. The feed pipe passes through the support frame and is connected at one end to the lifting plate. The other end of the feed pipe is connected to the telescopic base, and its side wall is provided with a plurality of discharge ports. The telescopic base extends and retracts, causing the feed pipe to vibrate up and down. A rotary drive ring is provided on the side wall of the feed pipe. Two scraping components are located below the support frame and are connected at one end to the side wall of the rotary drive ring. During operation, the scraping components abut against the side wall of the roadbed subsidence point and, under the action of the rotary drive ring, groove the side wall of the roadbed subsidence point.

[0005] Furthermore, the scraping assembly includes a rotating arm, a fixed ring, an upper rotating ring, a lower rotating ring, and a ball. The two ends of the rotating arm are rotatably connected to a rotary drive ring and a fixed ring, respectively. The upper and lower rotating rings are rotatably disposed at the upper and lower ends of the fixed ring, and both of them have several slotted rings on their side walls. The ball is rotatably embedded in the bottom of the lower rotating ring.

[0006] Furthermore, the wall scraping assembly also includes a dual-axis rotary motor, which is located inside the fixed ring and has its two ends of the rotating shafts connected to the upper rotating ring and the lower rotating ring, respectively.

[0007] Furthermore, a positioning protrusion is provided on the side of the fixing ring away from the rotating arm.

[0008] Furthermore, the top of the slotted ring is provided with several scrapers, and the slotted ring has a chip removal channel extending axially through one side of the scrapers.

[0009] Furthermore, the bottom of the lower rotating ring is provided with a brush ring, and the inner ring of the brush ring is provided with several intercepting rods along the radial direction, one end of which contacts the rolling ball.

[0010] Furthermore, the telescopic base includes a power component and a movable component. The power component connects the feed pipe and the movable component and drives the movable component to move up and down. The movable component includes a housing, a scraper, a rack, a gear, and a drive screw. The gear is coaxially disposed inside the housing, the scraper is disposed on the side wall of the housing, one end of the rack is connected to the scraper, and one side of the rack meshes with the gear. The drive screw is located below the housing, and one end of it passes through the bottom of the housing and meshes with the gear. The other end of the drive screw is provided with a spring. When the housing moves down, the drive screw contacts the ground and moves up, thereby causing the gear to rotate and drive the scraper to move away from the housing.

[0011] Furthermore, the bottom of the feed pipe is conical.

[0012] Furthermore, a buffer block is provided at the other end of the drive screw.

[0013] Secondly, the present invention provides a method for repairing roadbed subsidence, based on the roadbed subsidence repair device described above, specifically including the following steps:

[0014] S1: Erect support frames according to the area and location of the roadbed settlement points.

[0015] S2: Adjust the insertion depth of the feed pipe according to the depth of the roadbed settlement point. At this time, the ball on the scraper assembly first contacts the bottom of the roadbed settlement point, and the rotating drive ring is started to drive the scraper assembly to rotate. The descending feed pipe drives the fixed ring to move until the slotted ring is embedded in the side wall of the roadbed settlement point.

[0016] S3: Add filler material into the feed pipe, start the rotating drive ring to drive the scraper assembly to cut grooves on the side wall within the subsidence point of the roadbed, start the telescopic base to perform reciprocating telescopic movements to drive the feed pipe up and down and simultaneously empty the filler material in the feed pipe.

[0017] S4: When the material used for filling is exhausted, raise the feed tube and repeat steps S2-S3.

[0018] The composition of the filler material is changed according to the filling height.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are:

[0020] 1. This invention utilizes a feed pipe in conjunction with a telescopic base. The reaction force generated by the telescopic base against the ground causes the feed pipe to vibrate up and down, promoting the discharge of filling material from the feed pipe while simultaneously compacting the bottom of the roadbed subsidence point, thus increasing the compaction density of the subsidence point. By incorporating a scraper component whose radius gradually increases as the feed pipe penetrates deeper, it moves from the feed pipe as a starting point, rotating around the feed pipe while moving towards the inner wall of the roadbed subsidence point until its slotted ring is embedded in the inner wall of the subsidence point. This not only increases the bonding strength between the filling material and the interior of the roadbed subsidence point by slotting the side wall of the subsidence point, but also increases the diffusion of the filling material at the bottom of the roadbed subsidence point, enabling simultaneous grinding and filling inside the roadbed subsidence point, shortening the construction period, and achieving a high degree of automation.

[0021] 2. This invention connects the scraper assembly and the rotary drive ring by setting a fixed ring, and uses a dual-axis rotary motor to achieve rotation between the upper and lower rotating rings, thereby increasing the rotation of the scraper assembly and improving its grooving capability. At the same time, positioning protrusions are set on the side wall of the fixed ring to increase the resistance to rotation of the scraper assembly after it contacts the inner side of the roadbed settlement point, increasing its rotation dwell time. Combined with the scraper blade and chip removal channel, this enhances the grooving effect of the scraper assembly.

[0022] 3. The present invention sets up a movable component, and sets up a drive screw inside the component as a start switch to start the scraper to move. When the movable component reciprocates up and down in contact with the ground, it triggers the scraper to move radially, causing some of the filler material to enter under the movable component, so as to achieve the accumulation of filler material under it.

[0023] 4. This invention achieves high automation and good repair effect by setting the feed pipe to reciprocate along the axial direction and cooperating with the wall scraping component to achieve the layer-by-layer leveling of filling material at the roadbed subsidence point.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0052] Reference Figure 1-9 In a first aspect, the present invention provides a technical solution: a roadbed subsidence repair device based on road engineering, which includes a support frame 1, a feed pipe 2, a lifting plate 3, a wall scraping assembly 4, and a telescopic base 5.

[0053] The support frame 1 can be movably erected above the roadbed settlement point. Specifically, the support frame 1 can include a fixed plane, and then adjustable support rods can be rotatably set on the left and right sides of the fixed plane. The angle between the support rods and the plane can be adjusted to achieve positioning. If necessary, the support rods can have a telescopic function. At the same time, the support frame 1 can also be positioned with the assistance of external engineering vehicles, such as using a crane to achieve erection.

[0054] The lifting plate 3 is positioned above the support frame 1, with a telescopic component 6 between them. The telescopic component 6 is preferably a telescopic hydraulic cylinder, with its moving end facing upwards. A limiting post 61 is provided on the moving end of the telescopic component 6, and the lifting plate 3 is movably fitted onto the limiting post 61. If necessary, a second spring is fitted onto the limiting post 61, positioned above the lifting plate 3, to improve the flexibility of the feed pipe 2's vertical movement. The feed pipe 2 passes through the support frame 1 and is connected to the lifting plate 3 at one end, without being fixed together. Controlling the downward movement of the lifting plate 3 causes the feed pipe 2 to move downwards under gravity. The other end of the feed pipe 2 is connected to the telescopic base 5, and its sidewall is provided with several discharge ports 21. To prevent residual filling material, the bottom of the feed pipe 2 is conical. The telescopic base 5 extends and retracts, causing the feed pipe 2 to vibrate up and down. The telescopic base 5 includes a power component 51 and a movable component 52. The power component 51 connects the feed pipe 2 and the movable component 52 and drives the movable component 52 to move up and down. The power component 51 can be any device with a variable length. To facilitate the laying of filling material under the telescopic base 5, the movable component 52 includes a housing 521, a scraper 522, a rack 523, a gear 524, and a drive screw 525. The gear 524 is coaxially disposed inside the housing 521. The scraper 522 is disposed on the side wall of the housing 521. One end of the rack 523 is connected to the scraper 522, and one side of the rack 523 meshes with the gear 524. The drive screw 525 is located below the housing 521 and its... One end of the drive screw 525 passes through the bottom of the housing 521 and meshes with the gear 524. The other end of the drive screw 525 is equipped with a spring 526. When the housing 521 moves downward, the drive screw 525 contacts the ground and moves upward, causing the gear 524 to rotate and drive the scraper 522 to move away from the housing 521. When the housing 521 moves upward, the spring 526 drives the drive screw 525 to return to its original position, causing the scraper 522 to return to its original position and thus moving some of the filler material downwards from the housing 521. To increase service life, the other end of the drive screw 525 is equipped with a buffer block 527.

[0055] A rotary drive ring 7 is provided on the side wall of the feed pipe 2. Two scraper components 4 are located below the support frame 1 and one end is connected to the side wall of the rotary drive ring 7. During operation, the scraper components 4 abut against the side wall of the roadbed settlement point and groove the side wall of the roadbed settlement point under the action of the rotary drive ring 7. The scraper components 4 and the rotary drive ring 7 can be connected by a telescopic connecting rod. Alternatively, the scraper components 4 can include a rotating arm 41, a fixed ring 42, an upper rotating ring 43, a lower rotating ring 44, and a ball 45. The two ends of the rotating arm 41 are rotatably connected to the rotary drive ring 7 and the fixed ring 42, respectively. The upper rotating ring 43 and the lower rotating ring 44 are rotatably disposed at the upper and lower ends of the fixed ring 42, respectively, and both of them have several grooved rings 46 around their side walls. The ball 45 is rotatably embedded in the bottom of the lower rotating ring 44. To enhance the grooving effect of the scraper assembly 4, it also includes a dual-axis rotary motor 47. This motor 47 is located within the fixed ring 42, with its two ends connected to the upper rotating ring 43 and the lower rotating ring 44 respectively, enabling the rotation of the upper and lower rotating rings 43 and 44 within the scraper assembly. Several scraper blades 461 are provided on the top of the grooving ring 46, and a chip removal channel 462 extends axially through one side of each scraper blade 461. To increase the rotation dwell time of the upper and lower rotating rings 43 and 44, a positioning protrusion 421 is provided on the fixed ring 42 on the side away from the rotating arm 41. Simultaneously, the positioning protrusion 421 also extends the position change time of the scraper assembly 4 after the material below the feed pipe 2 is filled. To prevent soil from entering between the rolling ball 45 and the lower rotating ring 44, a brush ring 48 is provided at the bottom of the lower rotating ring 44. Several intercepting rods 481 are arranged radially around the inner ring of the brush ring 48, and one end of the intercepting rod 481 contacts the rolling ball 45.
