Abstract
Description
Technical Field
[0001] This utility model relates to the field of crack sealing device technology, and in particular to a road crack sealing device for preventing sedimentation during road and bridge construction. Background Technology
[0002] Road and bridge construction is a crucial part of highway construction, encompassing the entire process of building roads and bridges. It covers various stages from design and planning, pre-construction preparation, earthwork excavation and foundation construction, pavement laying, quality inspection, to environmental protection and maintenance. Cracks are one of the main forms of early-stage road and bridge defects, with transverse and longitudinal cracks being the most common linear cracks. Road crack sealing devices are used in the repair and maintenance of roads and bridges, typically employing asphalt or crack sealant to fill the cracks and extend the road's lifespan.
[0003] An existing anti-settling road crack sealing device for road and bridge construction (Announcement No.: CN221956503U) has at least the following drawbacks:
[0004] In the aforementioned patent, during the use of the device, the scraper is lowered to touch the ground, and the sprayed material from the discharge pipe is spread evenly to make the sprayed material in the crack more even. However, the discharge pipe is fixedly installed on the material tank. When filling some curved cracks, it is necessary to push the vehicle back and forth to twist so that the filling material can be poured into the crack. Since the vehicle is equipped with tank and other components, it is relatively bulky, making the back and forth twisting operation cumbersome. At the same time, the filling material is discharged directly from the discharge pipe without a component to control the flow rate, making it difficult for construction personnel to control the amount of material as needed, affecting the filling effect. Therefore, it is necessary to propose a road crack filling device for preventing sedimentation in road and bridge construction to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a road crack sealing device for preventing sedimentation during road and bridge construction.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A road crack sealing device for preventing sedimentation during road and bridge construction includes a handcart. A mixing tank is fixedly installed on the top surface of the handcart, and a PLC controller is fixedly installed on one side of the handcart. It also includes a material control component disposed on the top surface of the handcart for controlling the discharge of crack sealing material. The material control component includes a connecting pipe disposed on the top surface of the handcart, a movable pipe disposed on the top surface of the handcart, a valve fixedly installed on the bottom surface of the movable pipe, a fixing hole formed on the outer circular wall of the movable pipe, the connecting pipe passing through the fixing hole and fixedly connected downwards to the valve, and a discharge head fixedly fitted onto the inner circular wall of the valve. A support plate is fixedly installed on the outer circular wall of the moving tube. A support hole and a limiting groove are opened on one side of the support plate. A thin steel wire is movably sleeved inside the support hole. The thin steel wire is fixedly installed to the top surface of the valve handle. A spring is movably sleeved on the outer circular wall of the thin steel wire. A side handle is fixedly installed on the outer circular wall of the moving tube. Connecting plates are fixedly installed on both sides of the side handle. A first circular through hole is opened on one side of the connecting plate. A rotating plate is movably sleeved on the inner circular wall of the first circular through hole. The bottom surface of the rotating plate is fixedly installed to the thin steel wire. A pushing assembly is set inside the mixing tank and is used to push the grouting material out.
[0008] As a further embodiment of this utility model, the feeding assembly includes: a spiral rod disposed inside the mixing tank; second circular through holes are respectively opened on both sides of the mixing tank; the inner circular wall of the second circular through hole on the left side is fixedly sleeved with the connecting pipe; the inner circular wall of the second circular through hole on the right side is movably sleeved with the spiral rod; a drive motor is fixedly installed on one side of the mixing tank; the drive motor is electrically connected to the PLC controller; one end of the drive shaft of the drive motor is fixedly installed with the spiral rod.
[0009] As a further embodiment of this utility model, a support frame and a storage battery are fixedly installed on the top surface of the handcart, and the storage battery is electrically connected to the PLC controller.
[0010] As a further embodiment of this utility model, a limiting plate is fixedly installed on one side of the support frame, and the limiting plate is movably sleeved with the moving tube.
[0011] As a further embodiment of this utility model, a support box is fixedly installed on one side of the support frame.
[0012] As a further embodiment of this utility model, a main handle is fixedly installed on the outer circular wall of the moving tube.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By using a combination of a handcart, mixing tank, connecting pipe, moving pipe, fixing hole, and valve, the discharge speed of the grout can be controlled. Furthermore, manually moving the moving pipe along the discharge head facilitates filling winding and twisting gaps. Compared to the solution in the comparison document, there is no need to push the handcart to twist and move the grout. Additionally, the discharge speed can be adjusted by manually squeezing the rotating plate, allowing for easy control of the discharge volume as needed, ensuring effective grouting and making this solution quite practical.
[0015] 2. With the drive motor in place, when in use, starting the drive motor pushes the screw rod to rotate, which pushes the sealant inside the trolley into the connecting pipe, thereby maintaining a certain pressure on the sealant inside the connecting pipe, making it easy to control the discharge of the sealant.
[0016] 3. After the grouting is completed, the moving pipe is placed inside the support box using the set support frame and limiting plate. The support box can collect the residual waste inside the discharge head to prevent it from flowing everywhere, and provides vertical support for the moving pipe. The limiting plate provides lateral support for the main body of the moving pipe. Attached Figure Description

[0026] Reference Figures 1-5 A road crack sealing device for preventing sedimentation during road and bridge construction includes a handcart 1, a mixing tank 2 fixedly installed on the top surface of the handcart 1, and a PLC controller fixedly installed on one side of the handcart 1. It also includes a material control component, located on the top surface of the handcart 1, for controlling the discharge of the sealing material. The material control component includes a connecting pipe 3, located on the top surface of the handcart 1, a movable pipe 4 on the top surface of the handcart 1, a valve 6 fixedly installed on the bottom surface of the movable pipe 4, a fixing hole 5 on the outer circular wall of the movable pipe 4, the connecting pipe 3 passing through the fixing hole 5 and fixedly connected downwards to the valve 6, and a discharge head 7 fixedly connected to the inner circular wall of the valve 6. A support plate 8 is fixedly installed on the circular wall surface. A support hole 9 and a limiting groove 10 are opened on one side of the support plate 8. A thin steel wire 12 is movably sleeved inside the support hole 9. The thin steel wire 12 is fixedly installed on the top surface of the handle of the valve 6. A spring 11 is movably sleeved on the outer circular wall surface of the thin steel wire 12. A side handle 13 is fixedly installed on the outer circular wall surface of the moving tube 4. A connecting plate 15 is fixedly installed on both sides of the side handle 13. A first circular through hole is opened on one side of the connecting plate 15. A rotating plate 14 is movably sleeved on the inner circular wall surface of the first circular through hole. The bottom surface of the rotating plate 14 is fixedly installed with the thin steel wire 12. A pushing assembly is set inside the mixing tank 2 and is used to push the grouting material out.
[0027] In use, the rotating plate 14 is manually squeezed to rotate around the connecting plate 15. The rotation of the rotating plate 14 pulls the thin steel wire 12 to move inside the limiting groove 10 and the support hole 9. In turn, the thin steel wire 12 pulls the valve 6 switch handle. The flow rate of the valve 6 changes with the squeezing amplitude. Thus, the construction worker places the discharge head 7 obliquely against the top surface of the gap on the ground. As a result, the grout gradually flows out from the discharge head 7 and fills the gap. The rectangular shape of the discharge head 7 allows it to be filled parallel or perpendicular to the gap. The former is suitable for filling, and the latter is suitable for sealing. It also makes it easy to scrape the grout.
[0028] In this embodiment, the feeding assembly includes a screw rod 16, which is disposed inside the mixing tank 2. The mixing tank 2 has second circular through holes on both sides. The inner wall of the second circular through hole on the left side is fixedly sleeved with the connecting pipe 3, and the inner wall of the second circular through hole on the right side is movably sleeved with the screw rod 16. A drive motor 17 is fixedly installed on one side of the mixing tank 2. The drive motor 17 is electrically connected to the PLC controller, and one end of the drive shaft of the drive motor 17 is fixedly installed with the screw rod 16.
[0029] In use, the drive motor 17 is started to drive the screw rod 16 to rotate, which pushes the sealant inside the trolley 1 into the interior of the connecting pipe 3, thereby maintaining a certain pressure on the sealant inside the connecting pipe 3.
[0030] In this embodiment, a support frame 18 and a battery 22 are fixedly installed on the top surface of the handcart 1. The battery 22 is electrically connected to the PLC controller. A limit plate 19 is fixedly installed on one side of the support frame 18. The limit plate 19 is movably connected to the moving tube 4. A support box 20 is fixedly installed on one side of the support frame 18. A main handle 21 is fixedly installed on the outer circular wall of the moving tube 4.
[0031] In use, after the grouting is completed, the moving tube 4 is placed inside the support box 20 through the set support frame 18 and the limiting plate 19. The support box 20 can collect the waste material remaining inside the discharge head 7 and provide vertical support for the moving tube 4. The limiting plate 19 provides lateral support for the main body of the moving tube 4, which facilitates the placement of the moving tube 4.
[0032] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When a user needs to fill cracks in the ground on a bridge using the handcart 1, they push the handcart 1 to the vicinity of the location, then lift the main handle 21, raising it to move the bottom of the moving tube 4 out of the support box 20. The moving tube 4 is then rotated to move it out of the limiting plate 19, causing the connecting tube 3 to be removed from the top surface of the support frame 18. The other hand then grips the side handle 13, and the drive motor 17 is started to rotate the screw rod 16, pushing the filling material inside the handcart 1 into the connecting tube 3. At this time, the construction worker manually squeezes the rotating plate 14 to rotate around the connecting plate 15. The rotating plate 14 pulls the thin steel wire 12 to move within the limiting groove 10 and the support hole 9, thereby pulling the valve 6 switch handle, adjusting the flow rate of the valve 6. The amplitude changes with the amplitude of the pinching, so the construction worker places the discharge head 7 obliquely against the top surface of the crack on the ground. The sealant gradually flows from the discharge head 7 into the crack and onto the ground above the crack. The bottom of the discharge head 7 is rectangular, making it easy to spread the sealant. Furthermore, when the ground crack is winding, the discharge head 7 can be moved manually. When the hand is released, the thin steel wire 12 is pulled in the opposite direction by the spring 11, causing the valve 6's switch handle to rotate in the opposite direction and close the discharge. This achieves the effect of controlling the discharge speed of the sealant. Furthermore, manually lifting the moving tube 4 to move the discharge head 7 facilitates filling winding cracks. Compared to the scheme in the comparative document, there is no need to push the handcart 1 to twist and move the sealant, making it more convenient to use. At the same time, the discharge speed can be adjusted by manually pinching the rotating plate 14, allowing for easy control of the discharge amount as needed, ensuring the sealing effect, making it quite practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
