Description

Technical Field

[0001] The invention relates to the technical field of highway subgrade, and in particular to a highway subgrade reinforcement device. Background Art

[0002] The construction of highways has greatly improved the efficiency of logistics and transportation in modern society. However, due to the influence of geology and topography, there are certain difficulties in the construction of highways, especially in soft geological sections. However, after a long time, roadbed settlement and deformation are still prone to occur. Due to the influence of geographical location, there are still many objective factors, so roadbed reinforcement devices are usually used to reinforce the soil.

[0003] However, the highway roadbed reinforcement devices on the market are usually one-to-one in size, with fewer adjustable functions, and are not easy to meet the various needs of people during use, thereby reducing the use of the device and increasing the cost of use. Therefore, a highway roadbed reinforcement device is needed. Summary of the invention

[0004] The purpose of the present invention is to provide a highway roadbed reinforcement device, which solves the problem that the highway roadbed reinforcement devices on the market in the prior art are usually one-to-one in size, have fewer adjustable functions, poor applicability, and are not easy to meet various needs of people during use, thereby reducing the use of the device and increasing the cost of use.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a highway roadbed reinforcement device, comprising an outer frame, the top of the outer frame is connected to a slide plate through a first electric telescopic rod, the slide plate is provided with a first through hole, a first rotating shaft is rotatably connected in the first through hole, a second through hole is provided on the first rotating shaft, a screw sleeve is provided in the second through hole, a threaded rod is provided on the top of the screw sleeve, and one end of the threaded rod passes through the screw sleeve and extends to the inner cavity of the outer frame, the extended end of the threaded rod is rotatably connected to an electromagnetic roller through the second rotating shaft, and the electric Two pressing clamps are symmetrically hinged on the magnetic roller, a torsion spring for resetting the pressing clamp is arranged between the pressing clamp and the electromagnetic roller, a fixing plate is arranged at one end of the pressing clamp away from the electromagnetic roller, a plurality of multi-stage electric telescopic rods distributed in an array are arranged on the side wall of one end of the fixing plate away from the pressing clamp, a flexible elastic plate is arranged on the side wall of one end of the fixing plate away from the pressing clamp, a groove for accommodating the multi-stage electric telescopic rod is arranged on the flexible elastic plate, one end of the multi-stage electric telescopic rod is connected to the fixing plate, and the other end of the multi-stage electric telescopic rod is fixedly connected to the bottom wall of the groove;

[0006] The inner cavity of the outer frame is symmetrically provided with fastening parts, and the fastening parts include a push plate, and both sides of the outer wall of one side of the push plate are connected with round rods penetrating the side wall of the outer frame, and a protection box is provided on one side of the extended end of the round rod, and one side of the protection box is fixedly connected to one side of the adjacent outer frame, and the inner cavity of the protection box is provided with a short rod, and one end of the short rod penetrates the protection box, and the other end of the short rod is fixedly connected to the extended end of the adjacent round rod, the outer ring of the short rod is sleeved with a baffle located in the inner cavity of the protection box, and the outer ring of the short rod is installed with a spring, and one side of the baffle is elastically connected to one side of the adjacent outer frame through the spring;

[0007] The slide plate is moved to the middle position of the outer frame by controlling the first electric telescopic rod, and then the threaded rod is repeatedly swung to control the electromagnetic roller corresponding to the side where the soil is scraped to be energized, and the multi-stage electric telescopic rod is controlled to contract. The electromagnetic roller is energized and magnetically attracted to the lower pressure clamp corresponding to the side where the soil is scraped. The swing of the threaded rod will drive the lower pressure clamp corresponding to the electromagnetic roller to rotate, so that the flexible elastic plate swings and knocks the soil on the highway roadbed, thereby beating and compacting the side wall of the roadbed.

[0008] The present invention also has the following beneficial effects:

[0009] 1. The present invention sets a multi-stage electric telescopic rod and controls the extension length of the multi-stage electric telescopic rod, so that the device is suitable for fixing and reinforcing roadbeds of various heights; the present invention adopts a structural design to make the device suitable for reinforcing foundations of different heights, and the downward pressure of the inner cavity of the device on the soil layer can be adjusted as needed, thereby meeting the different needs of personnel in use and improving the applicability of the device.

[0010] 2. The present invention sets a multi-stage electric telescopic rod and fills the through groove with a preset first air pressure. The first air pressure will not cause the inner wall of the through groove to expand and deform, so that the inflated through groove acts as a reinforcing rib of the flexible elastic plate. The first electric telescopic rod is controlled to extend and the slide plate is moved to one side of the outer frame. The threaded rod is then adjusted to make the lower surface of the flexible elastic plate contact the ground. The stepper motor is controlled to rotate and drive the flexible elastic plate to rotate. The flexible elastic plate rotates and drives the scraper to rotate into the outer frame. At the same time, the multi-stage electric telescopic rod is controlled to extend so that the scraper always keeps in contact with the ground, so that the soil lost from the highway roadbed can be scraped onto the highway roadbed, thereby improving the reinforcement efficiency.

[0011] 3. The present invention controls the slide plate to move to its original position by setting a multi-stage electric telescopic rod, and then repeatedly swings the threaded rod to control the electromagnetic roller corresponding to the side where the soil is scraped to be energized, and controls the multi-stage electric telescopic rod to shrink. The electromagnetic roller is energized and magnetically attracted to the downward pressure clamp corresponding to the side where the soil is scraped. The swing of the threaded rod will drive the downward pressure clamp corresponding to the electromagnetic roller to rotate, so that the flexible elastic plate swings and strikes the soil on the highway roadbed, thereby beating and compacting the side wall of the roadbed.

[0012] 4. The present invention sets a multi-stage electric telescopic rod, controls the first electric telescopic rod to return to its original state, and then rotates the threaded rod to push the lower pressure clamp downward to compact the floating soil on the surface during the hammering process. At the same time, by filling the through groove with a preset second air pressure gas, the side of the flexible elastic plate in contact with the roadbed is deformed to form criss-cross protrusions, so that the protrusion contacts the foundation, and then leaves a protruding groove to form a drainage ditch, thereby reducing soil and water loss, thereby completing the roadbed reinforcement.

It should be emphasized that since the flexible elastic plate 11 is elastic, the extension and contraction of the multi-stage electric telescopic rod 10 can be applied to the reinforcement of highway roadbeds of different heights.

[0026] The inner cavity of the outer frame 1 is symmetrically provided with a fastening part 6, and the fastening part 6 includes a push plate 601. Both sides of the outer wall of one side of the push plate 601 are connected with a round rod 602 that penetrates the side wall of the outer frame 1, and a protective box 603 is provided on one side of the extended end of the round rod 602, and one side of the protective box 603 is fixedly connected to one side of the adjacent outer frame 1, and a short rod 604 is provided in the inner cavity of the protective box 603, and one end of the short rod 604 penetrates the protective box 603, and the other end of the short rod 604 is fixedly connected to the extended end of the adjacent round rod 602, the outer ring of the short rod 604 and the inner cavity of the protective box 603 are sleeved with a baffle 605, and the outer ring of the short rod 604 is installed with a spring 606, and one side of the baffle 605 is elastically connected to one side of the adjacent outer frame 1 through the spring 606.

[0027] The other end of the baffle 605 is fixedly connected to one end of the spring 606, and the other end of the spring 606 is fixedly connected to the outer wall of the adjacent outer frame 1; specifically, through the arrangement of the baffle 605 and the spring 606, the push plate 601 has an inward squeezing force.

[0030] A plurality of crisscrossing through grooves are provided inside the side of the flexible elastic plate 11 in contact with the roadbed, and the through grooves are connected to the air pump through a conduit, and are also connected to the atmosphere through a conduit and an exhaust valve; by setting the through grooves, a preset first air pressure gas is filled into the through grooves, and the first air pressure is an air pressure that will not cause the inner wall of the through groove to expand and deform, so that the inflated through grooves act as reinforcement ribs of the flexible elastic plate 11, reducing the degree of deformation of the flexible elastic plate 11; by filling the through grooves with a preset second air pressure gas, the second air pressure is an air pressure that can cause the inner wall of the through groove to expand and deform, so that the side of the flexible elastic plate 11 in contact with the roadbed is deformed to form crisscrossing protrusions, so that the protrusions contact the foundation, and then a protruding groove is left on the roadbed to form a drainage ditch, thereby reducing soil erosion.

[0031] A wear-resistant layer is sprayed on one side wall of the flexible elastic plate 11 in contact with the roadbed. Specifically, by spraying the wear-resistant layer, the service life of the flexible elastic plate 11 is increased, thereby increasing the service life of the device.

[0032] Storage grooves are provided at the four corners of the front and rear side walls of the outer frame 1, and movable components are provided in the storage grooves. By providing the storage grooves, when the mobile device needs to be moved, the mobile component is extended from the storage groove to quickly move the device. When the mobile device is not needed, the mobile component is stored in the storage groove.

[0033] A scraper 13 is provided on the lower surface of the flexible elastic plate 11, and a cone tooth 14 is provided on the scraper 13; the cone tooth 14 is provided to facilitate scraping soil from hard land, thereby improving work efficiency.

[0034] When in use, the device is moved to the place where the roadbed needs to be reinforced through the moving component, and a preset first air pressure is filled into the through groove. The above-mentioned first air pressure will not cause the inner wall of the through groove to expand and deform, so that the inflated through groove acts as a reinforcing rib of the flexible elastic plate 11, reducing the deformation performance of the flexible elastic plate 11, and then the first electric telescopic rod 101 is controlled to extend, and the slide plate 102 is moved to one side of the outer frame 1, and then the threaded rod 3 is adjusted to make the lower surface of the flexible elastic plate 11 contact with the ground, and then the stepper motor is controlled to rotate, the stepper motor rotates and drives the flexible elastic plate 11 to rotate, the flexible elastic plate 11 rotates and drives the scraper 13 to rotate into the outer frame 1, and at the same time the multi-stage electric The movable telescopic rod 10 is extended to keep the scraper 13 in contact with the ground at all times, so that the soil lost from the highway roadbed can be scraped onto the highway roadbed, thereby improving the reinforcement efficiency; then the slide plate 102 is moved to the middle position of the outer frame 1 by controlling the first electric telescopic rod 101, and then the threaded rod 3 is repeatedly swung, and the electromagnetic roller 7 corresponding to the side where the soil is scraped is energized, and the multi-stage electric telescopic rod 10 is controlled to contract, and the electromagnetic roller 7 is energized and magnetically attracted to the lower pressure clamp 4 corresponding to the side where the soil is scraped. The swing of the threaded rod 3 will drive the lower pressure clamp 4 corresponding to the electromagnetic roller 7 to rotate, so that the flexible elastic plate 11 swings and knocks the soil on the highway roadbed, thereby beating and compacting the side wall of the roadbed.

[0035] When it is necessary to level the foundation at the top, the first electric telescopic rod 101 corresponding to the side close to the scraped soil is controlled to extend, and the first electric telescopic rod 101 corresponding to the side away from the scraped soil is controlled to contract, so that the flexible elastic plate 11 levels the foundation at the top, and then the first electric telescopic rod 101 corresponding to the side close to the scraped soil is controlled to contract, and the first electric telescopic rod 101 corresponding to the side away from the scraped soil is controlled to extend, and the first electric telescopic rod 101 corresponding to the side close to the scraped soil is controlled to contract, and the multi-stage electric telescopic rod 10 is repeatedly controlled to extend and contract, so as to hammer and compact the foundation at the top.

[0036] After the top and the sides are hammered and compacted, the first electric telescopic rod 101 is controlled to return to its original state and then the threaded rod 3 is rotated to push the lower pressing clamp 4 downward to compact the floating soil on the surface during the hammering process. At the same time, a preset second air pressure gas is filled into the through groove to deform the side of the flexible elastic plate 11 in contact with the roadbed to form criss-cross protrusions, so that the protrusions contact the foundation, leaving protruding grooves to form drainage grooves, thereby reducing soil and water loss, thereby completing the roadbed reinforcement.

[0037] The present invention also provides a method for reinforcing a highway subgrade, and the detailed operation steps are as follows:

[0038] S1. By filling the through groove with a preset first air pressure gas, the inflated through groove acts as a reinforcing rib of the flexible elastic plate 11, reducing the deformation performance of the flexible elastic plate 11, and then controlling the first electric telescopic rod 101 to extend and move the slide plate 102 to one side of the outer frame 1, and then adjusting the threaded rod 3 to make the lower surface of the flexible elastic plate 11 contact with the ground, and then controlling the multi-stage electric telescopic rod 10 to extend by shaking the threaded rod 3, so that the scraper 13 always keeps in contact with the ground, thereby scraping the soil lost from the highway roadbed onto the highway roadbed;

[0039] S11, in the process of the flexible elastic plate 11 scraping the soil lost from the roadbed, by filling the through groove with a preset first air pressure, the first air pressure will not cause the inner wall of the through groove to expand and deform, so that the inflated through groove acts as a reinforcing rib of the flexible elastic plate 11, reduces the deformation performance of the flexible elastic plate 11, and improves the ability to scrape soil;

[0040] S2, by controlling the first electric telescopic rod 101 to move the slide plate 102 to the middle position of the outer frame 1, and then by repeatedly swinging the threaded rod 3, the electromagnetic roller 7 corresponding to the side where the soil is scraped is energized, and the multi-stage electric telescopic rod 10 is controlled to contract, and the electromagnetic roller 7 is energized to magnetically engage with the lower pressure clamp 4 corresponding to the side where the soil is scraped. The swing of the threaded rod 3 will drive the lower pressure clamp 4 corresponding to the electromagnetic roller 7 to rotate, so that the flexible elastic plate 11 swings and knocks the soil on the roadbed, and then the side wall of the roadbed is slapped and compacted;

[0041] S3, by controlling the first electric telescopic rod 101 corresponding to the side close to the scraped soil to extend, and controlling the first electric telescopic rod 101 corresponding to the side far from the scraped soil to contract, so that the flexible elastic plate 11 levels the top foundation, and then controlling the first electric telescopic rod 101 corresponding to the side close to the scraped soil to contract, and controlling the first electric telescopic rod 101 corresponding to the side far from the scraped soil to extend, and controlling the first electric telescopic rod 101 corresponding to the side close to the scraped soil to contract, and controlling the multi-stage electric telescopic rod 10 to repeatedly extend and contract, so as to hammer and compact the top foundation;

[0042] S4, after controlling the first electric telescopic rod 101 to return to the original state, the threaded rod 3 is rotated to make the threaded rod 3 push the pressing clamp 4 downward to compact the floating soil on the top of the roadbed and the surface layer of the side wall.

[0043] S41. In the process of the threaded rod 3 pushing the pressing clamp 4 downward to compact the floating soil on the top and side walls of the roadbed, a preset second air pressure gas is filled into the through groove to deform the side of the flexible elastic plate 11 in contact with the roadbed to form criss-cross protrusions, so that the protrusions contact the foundation, leaving protruding grooves to form drainage grooves, thereby reducing soil and water loss, thereby completing the roadbed reinforcement.
