Road settlement grouting repair device

Abstract

This application provides a road settlement grouting repair device, relating to the field of road engineering construction technology, including a moving component, a storage cylinder, a grouting component, a mixing component, and a guiding component. By setting up a guiding component, the moving component drives the guiding plate to rotate. On one hand, this continuously guides the grout from the lower layer of the storage cylinder to the upper layer, effectively reducing the contact area between the upper grout and air, slowing down the rate of water evaporation, and preventing slurry stratification and solidification. On the other hand, when the connecting shaft rotates, the pulling ring drives the horizontal plate to reciprocate up and down, further breaking up any potential localized solidification or stratification of the upper grout, enhancing the uniformity of grout mixing, effectively avoiding grouting quality problems caused by grout issues, and further improving the efficiency and quality of the grouting process.

Description

Technical Field

[0001] This application relates to the field of road construction technology, and in particular to a road settlement grouting repair device. Background Technology

[0002] In road settlement construction, grouting is a commonly used and effective method for reinforcing and repairing foundation problems. Its core principle is to inject specific grout materials into the stratum to change the physical properties and engineering performance of the stratum, thereby achieving many purposes such as reinforcement, densification, waterproofing, seepage prevention, and drainage.

[0003] In actual grouting operations, the grout storage cylinder needs to be transported to the designated location where road subsidence needs repair using a moving component. However, during the movement, the grout inside the storage cylinder is basically stationary. Due to the different densities of the various components of the grout, stratification is likely to occur when it is stationary. Moreover, the upper layer of grout has a large contact area with the air, so the water evaporates quickly and it is more likely to solidify. When it is time to start the mixing component for grouting, the solidified upper layer of grout will increase its operating resistance, resulting in increased load on the mixing component, increased energy consumption, and slower operating speed. It will be unable to quickly and fully mix the grout, which will prolong the grout preparation time and prevent the timely provision of uniform and suitable grout during grouting, ultimately reducing the overall grouting efficiency. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a road settlement grouting repair device that can overcome or at least partially solve the above problems.

[0008] In some implementations, the grouting assembly includes a mortar pump fixedly connected to the top of the base plate. The inlet end of the mortar pump is connected to the bottom of the storage cylinder via a connecting pipe with a control valve. The outlet end of the mortar pump is connected to a grout hose, and the end of the grout hose connected away from the outlet end of the mortar pump is connected to a grouting head.

[0009] In some implementations, the stirring assembly includes an I-shaped mounting bracket fixedly connected between two protrusions at the top of the storage cylinder. A drive unit is mounted on the top of the I-shaped mounting bracket. An stirring rod extending into the storage cylinder is fixedly connected to the output end of the drive unit. Two sets of stirring blades are fixedly connected to the stirring rod, with each set containing three stirring blades.

[0010] In some implementations, the material guiding assembly includes a first material guiding pipe with a control valve. One end of the first material guiding pipe is connected to the bottom of the storage cylinder, and the other end of the first material guiding pipe is connected to the material guiding cylinder. A connecting shaft is rotatably arranged between two L-shaped supports on both sides of the material guiding cylinder. Multiple circumferentially distributed material guiding plates, all of which are in contact with the inner wall of the material guiding cylinder, are fixedly connected to the surface of the connecting shaft. A transmission assembly is provided between one end of the connecting shaft and the surface of the rotating rod. The bottom of the material guiding cylinder is connected to a second material guiding pipe that is limited between the L-shaped support and the top protrusion of the storage cylinder. The end of the second material guiding pipe that is away from the bottom of the material guiding cylinder is inclined towards the top port of the storage cylinder.

[0011] In some implementations, the transmission assembly includes a bevel gear one fixedly connected to one end of a connecting shaft, a matching bevel gear two connected to the surface of the bevel gear one, a transmission rod fixedly connected to the bottom of the bevel gear two, the surface of the transmission rod being rotatably connected between the top and bottom of a base plate via a bearing, a bevel gear three fixedly connected to the end of the transmission rod away from the bottom of the bevel gear two, and a matching bevel gear four fixedly connected to the surface of the rotating rod on the surface of the bevel gear three.

[0012] In some implementations, the inner wall of the feed guide cylinder is slidably connected to a pull ring near the upper layer of slurry inside the storage cylinder. Multiple intersecting horizontal plates are fixedly connected between the inner walls of the pull ring. A sleeve that fits against the surface of the stirring rod is fixedly connected between the top and bottom of the horizontal plates. A pull assembly is linked between the surface of the sleeve and the surface of the connecting shaft.

[0013] In some implementations, the pulling assembly includes a pair of horizontal limiting blocks fixedly connected to the surface of the storage cylinder. An L-shaped rod is slidably connected between the top and bottom of each horizontal limiting block. One end of the L-shaped rod is fixedly connected to the top of the sleeve surface, and the other end of the L-shaped rod is fixedly connected to an abutment. A spring sleeved on the surface of the L-shaped rod is fixedly connected between the top of the abutment and the bottom of the horizontal limiting block. A rotating part fixedly connected to the surface of the connecting shaft is attached to the surface of the abutment.

[0014] In some implementations, the contact part is a semi-circular structure, and the rotating part is a cam structure.

[0015] By adopting the above technical solution, this application has the following beneficial effects compared with the prior art: This application, by setting up a material guiding component, uses the power of the moving component to drive the material guiding plate to rotate. On the one hand, it can guide the lower layer of slurry in the storage cylinder to the upper layer, thereby effectively reducing the contact area between the upper layer of slurry and air, slowing down the rate of water evaporation, avoiding slurry stratification and solidification, and ensuring the uniformity of the slurry. This not only shortens the slurry preparation time, but also provides suitable slurry for the grouting process in a timely manner, significantly improving grouting efficiency and quality. On the other hand, when the connecting shaft rotates, the pulling ring will drive the horizontal plate to move up and down reciprocatingly, further breaking the possible local solidification or stratification of the upper layer of slurry, enhancing the mixing uniformity of the slurry, effectively avoiding grouting quality problems caused by slurry issues, and further improving the efficiency and quality of the grouting process.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0019] like Figures 1-3 As shown, a road settlement grouting repair device includes a moving component 1, a storage cylinder 2, a grouting component 3, a mixing component 4, and a material guiding component 5.

[0020] like Figure 3 and Figure 4 As shown, the movable component 1 includes a base plate 11. A pair of universal wheels 12 with braking function are installed on one side of the bottom of the base plate 11. A pair of vertical mounting blocks 13 are fixedly connected to the other side of the bottom of the base plate 11. A rotating rod 14 is rotatably arranged between the two vertical mounting blocks 13. The two ends of the rotating rod 14 are respectively fixedly connected to movable wheels 15. A push handle 16 is installed on one side of the top of the base plate 11.

[0021] The storage cylinder 2 is used to store the materials required for grouting. Its top is open to facilitate the addition of materials. The storage cylinder 2 is fixedly connected to the top of the base plate 11 by multiple circumferentially distributed L-shaped brackets 21. This connection method ensures the stability of the storage cylinder 2 and does not hinder the movement of the device.

[0022] In actual use, the operator only needs to hold the push handle 16 and apply a certain amount of force. The device will move smoothly with the support of the casters 12 and the moving wheels 15. The operator can easily move the device to the specific location where the road settlement needs to be repaired. When the device reaches the designated position, step on the brake pedal of the caster 12 to quickly fix the device position and make full preparations for subsequent grouting operations.

[0023] like Figures 1-6 As shown, the grouting assembly 3 includes a mortar pump 31 fixedly connected to the top of the base plate 11. A connecting pipe 32 with a control valve connects the inlet end of the mortar pump 31 to the bottom of the storage cylinder 2. A grout hose 33 connects to the outlet end of the mortar pump 31. A grouting head 34 is connected to the end of the grout hose 33 furthest from the outlet end of the mortar pump 31. When the road settlement repair device reaches the designated position and is fixed, the operator opens the control valve on the connecting pipe 32. At this time, the grouting material stored in the storage cylinder 2 flows into the inlet end of the mortar pump 31 through the connecting pipe 32 under its own gravity. Then, the mortar pump 31 is started. Under the action of pump 31, grouting material will continuously enter the grout pump 31 from the storage cylinder 2. Subsequently, the grout pump 31 pressurizes the grouting material, so that it is transported through the grout hose 33 at a certain flow rate and pressure. Since the grout hose 33 has good flexibility and pressure resistance, it can adapt to different construction environments and angles, accurately delivering the pressurized grouting material to the grouting head 34. Finally, the grouting head 34 will inject the grouting material into the foundation of the settlement area at an appropriate pressure and flow rate according to the specific conditions of the road settlement area, filling the voids in the foundation, reinforcing the soil, and thus achieving the purpose of repairing road settlement.

[0024] like Figure 5 and Figure 6 As shown, the stirring assembly 4 is vertically installed on the top of the storage cylinder 2, and its stirring end extends into the interior of the storage cylinder 2. Specifically, the stirring assembly 4 includes an I-shaped mounting bracket 41 fixedly connected between two protrusions on the top of the storage cylinder 2. A drive unit 42 is installed on the top of the I-shaped mounting bracket 41. A stirring rod 43 extending into the interior of the storage cylinder 2 is fixedly connected to the output end of the drive unit 42. Two sets of stirring blades 44 are fixedly connected to the stirring rod 43, and each set of stirring blades 44 has three blades.

[0025] During the grouting process, the drive unit 42, which uses a servo motor, drives the stirring rod 43 to rotate, thereby causing the stirring blades 44 on the stirring rod 43 to continuously stir the grout in the storage cylinder 2. This effectively prevents the grout from settling or segregating during transportation, ensuring the uniformity and fluidity of the grout, thus ensuring the grouting quality and making the road settlement repair effect more ideal.

[0026] In practical applications, the slurry in the storage cylinder 2 is usually continuously stirred by the mixing component 4 only during the grouting process. That is to say, when the road settlement repair device moves to the designated position with the help of the moving component 1, the slurry in the storage cylinder 2 is basically in a static state. Due to the density difference of different components in the slurry, stratification will occur in the static state. Moreover, the upper layer of slurry has a larger contact area with air and evaporates water faster. Therefore, the upper layer of slurry is often more prone to solidification than the lower layer of slurry. When the mixing component 4 is started in preparation for grouting, the solidified upper layer of slurry will increase the operating resistance of the mixing component 4. Because the solidified upper layer of slurry becomes harder and more viscous, the mixing component 4 needs to overcome greater force to rotate these solidified parts. This leads to an increased load on the mixing component 4. In order to maintain normal mixing, the mixing component 4 has to consume more energy, and the operating speed may also slow down. It is not possible to quickly and fully mix the slurry, which will lead to a longer slurry preparation time and the inability to provide uniform and suitable slurry in a timely manner during the grouting process, thereby reducing the overall grouting efficiency.

[0027] To address the aforementioned issues of grout stratification during static conditions and the tendency of the upper layer to solidify, thus affecting grouting efficiency, such as... Figures 5-7 As shown, the material guiding assembly 5 includes a material guiding pipe 51 with a control valve. One end of the material guiding pipe 51 is connected to the bottom of the storage cylinder 2, and the other end of the material guiding pipe 51 is connected to a material guiding cylinder 52. A connecting shaft 53 is rotatably arranged between two L-shaped supports 21 on both sides of the material guiding cylinder 52. Multiple circumferentially distributed material guiding plates 510, all of which are in contact with the inner wall of the material guiding cylinder 52, are fixedly connected to the surface of the connecting shaft 53. A transmission assembly 55 is provided between one end of the connecting shaft 53 and the surface of the rotating rod 14. The transmission assembly 55 includes a bevel gear 551 fixedly connected to one end of the connecting shaft 53. The surface of the bevel gear 551 is connected to a matching conical gear. The bottom of the bevel gear 552 is fixedly connected to a transmission rod 553. The surface of the transmission rod 553 is rotatably connected between the top and bottom of the base plate 11 via a bearing. The end of the transmission rod 553 away from the bottom of the bevel gear 552 is fixedly connected to a bevel gear 554. The surface of the bevel gear 554 is connected to a bevel gear 555 that is compatible with and fixedly connected to the surface of the rotating rod 14. The bottom of the guide cylinder 52 is connected to a guide pipe 54 that is limited between the L-shaped bracket 21 and the top protrusion of the storage cylinder 2. The end of the guide pipe 54 away from the bottom of the guide cylinder 52 is inclined towards the top port of the storage cylinder 2.

[0028] After adopting the above technical solution, the power of the moving component 1 can be used to drive the material guiding component 5. Specifically, when the moving wheel 15 in the moving component 1 rotates, it will drive the rotating rod 14 to rotate synchronously. The rotation of the rotating rod 14 causes the bevel gear 4 555 fixed on its surface to rotate accordingly. Since the bevel gear 4 555 is adapted to bevel gear 3 554, the bevel gear 3 554 will rotate accordingly, thereby driving the transmission rod 553 to rotate. The rotation of the transmission rod 553 will cause the bevel gear 2 552 to rotate. Since the bevel gear 2 552 is adapted to bevel gear 1 551, the bevel gear 1 551 will also rotate. Since the bevel gear 1 551 is fixed at one end of the connecting shaft 53, the connecting shaft 53 will rotate accordingly, thereby driving the three circumferentially distributed material guiding plates 510 on the connecting shaft 53 to rotate along the inner wall of the material guiding cylinder 52.

[0029] At this time, if the control valve on the feed pipe 51 is opened, the lower layer of slurry in the storage cylinder 2 will enter the feed pipe 52 under the action of gravity. As the feed guide plate 510 continues to rotate, the lower layer of slurry will be continuously pushed and introduced into the upper layer of slurry in the storage cylinder 2 through the feed pipe 54. As the lower layer of slurry is continuously introduced to cover the upper layer of slurry, the contact area between the upper layer of slurry and the air is reduced, the evaporation rate of water is slowed down, and the lower layer of slurry and the upper layer of slurry are continuously mixed, avoiding the stratification phenomenon caused by density difference, effectively preventing the upper layer of slurry from solidifying due to rapid evaporation of water, thereby ensuring the uniformity of the slurry and improving the grouting efficiency.

[0030] It should also be noted that this application utilizes the power of the moving component 1 to drive the material guiding component, thereby avoiding the introduction of an additional power source and reducing energy consumption. At the same time, since the solidification of the slurry is effectively prevented, the load on the mixing component 4 is reduced, thereby reducing the energy consumption of the mixing component 4, extending the service life of the equipment, and ultimately reducing the overall cost of road settlement repair.

[0031] like Figures 5-8As shown, a pulling ring 56 is slidably connected to the inner wall of the feed cylinder 52, close to the upper layer of slurry inside the storage cylinder 2. Multiple intersecting transverse plates 57 are fixedly connected between the inner walls of the pulling ring 56. A sleeve 58, which is in contact with the surface of the stirring rod 43, is fixedly connected between the top and bottom of the transverse plates 57. A pulling assembly 59 is linked between the surface of the sleeve 58 and the surface of the connecting shaft 53. The pulling assembly 59 includes a pair of transverse limiting blocks 591 fixedly connected to the surface of the storage cylinder 2. Each transverse limiting block 591... An L-shaped rod 592 is slidably connected between the top and bottom. One end of the L-shaped rod 592 is fixedly connected to the top of the surface of the sleeve 58, and the other end of the L-shaped rod 592 is fixedly connected to an abutment part 593. A spring 594 sleeved on the surface of the L-shaped rod 592 is fixedly connected between the top of the abutment part 593 and the bottom of the horizontal limit block 591. A rotating part 595 fixedly connected to the surface of the connecting shaft 53 is attached to the surface of the abutment part 593. The abutment part 593 has a semi-circular structure, and the rotating part 595 has a cam structure.

[0032] When the connecting shaft 53 rotates, the two rotating parts 595 on the surface of the connecting shaft 53 will rotate along the surface of the contact part 593. Since the contact part 593 has a semi-circular structure and the rotating part 595 has a cam structure, when the protruding part of the rotating part 595 rotates to the surface of the contact part 593, it will apply an upward pressure to the contact part 593. Under this pressure, the contact part 593 will squeeze the spring 594 sleeved on the surface of the L-shaped rod 592, causing it to undergo elastic deformation. At the same time, it will drive the L-shaped rod 592 to move upward. Since one end of the L-shaped rod 592 is fixedly connected to the top end of the sleeve 58, the upward movement of the L-shaped rod 592 will drive the sleeve 58 to slide upward along the surface of the stirring rod 43. And since the sleeve 58 is fixedly connected to the top end of the sleeve 58, the upward movement of the L-shaped rod 592 will drive the sleeve 58 to slide upward along the surface of the stirring rod 43. The sleeve 58 is fixedly connected between the top and bottom of the cross plate 57. The cross plates 57 are intersecting and fixedly connected between the inner walls of the pull ring 56. Therefore, when the sleeve 58 slides upward, it will drive the pull ring 56 to move upward on the inner wall of the guide cylinder 52. During the upward movement of the pull ring 56, the cross plates 57 intersecting between its inner walls can pull up the slurry near the upper layer in the storage cylinder 2 to a greater extent. As the connecting shaft 53 continues to rotate, the protruding part of the rotating part 595 will gradually leave the surface of the contact part 593. At this time, the spring 594 will push the contact part 593 upward under the action of its own elastic restoring force, thereby driving the L-shaped rod 592, the sleeve 58 and the pull ring 56 to move downward, so that the cross plate 57 returns to the initial position.

[0033] This process is repeated. As the connecting shaft 53 rotates continuously, the pulling ring 56 drives the horizontal plate 57 to move up and down in the storage cylinder 2, constantly pulling the upper layer of slurry up and down. This action can further break up any local solidification or stratification that may form in the upper layer of slurry, allowing the upper layer of slurry to mix fully with the lower layer of slurry and the upper layer of slurry covering layer introduced through the guide pipe 2 54. This greatly enhances the uniformity of the slurry, effectively avoids grouting quality problems caused by uneven slurry, and further improves the efficiency and quality of the entire grouting process.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of this application.
