Description

Technical Field

[0001] This utility model relates to the field of straightening equipment, specifically to a road and bridge crack reinforcement device. Background Technology

[0002] Cracks easily appear in roads and bridges during use. Once cracks appear, the strength of the damaged area decreases, the load-bearing capacity is greatly reduced, and it is more susceptible to erosion by rainwater. If the cracks are not treated, the damage will continue to expand, eventually leading to major repairs or even scrapping of the road or bridge. In severe cases, it can even cause the bridge to collapse. Therefore, it is necessary to reinforce the cracks with grouting.

[0003] According to patent document CN220352586U, a road and bridge construction device for reinforcing bridge cracks includes a flat plate. The flat plate is equipped with an injection mechanism, a dust extraction mechanism, and a dust collection mechanism. The injection mechanism includes a glue bucket, two first electric push rods, a pressure plate, a pressure rod, a piston, an injection hose, an injection nozzle, a strip plate, and two second electric push rods. The glue bucket is fixedly installed on the top of the flat plate, and both first electric push rods are fixedly installed on the top of the glue bucket. The pressure plate is fixedly installed on the output shafts of the two first electric push rods, and the pressure rod is fixedly installed on the bottom of the pressure plate. This technical solution, by setting up the injection mechanism, allows for simple and effective injection of repair glue into bridge cracks, thereby repairing and reinforcing the bridge cracks. However, while this solution achieves glue reinforcement, it cannot adjust the discharge diameter according to the crack width, and cannot quickly inject the glue into the crack, resulting in inconvenience during use. Therefore, there is an urgent need to design a road and bridge crack reinforcement device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a road and bridge crack reinforcement device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a road and bridge crack reinforcement device, comprising a base, a support seat fixed to the bottom of the base, a caster wheel fixedly installed at the bottom of the support seat, a support tube welded to the base, a support column movably installed inside the support tube, a barrel fixed to one end of the support column, a cover plate movably installed on the top of the barrel, a drive motor and a feed hopper fixedly installed on the cover plate, a power mechanism fixed to the base, an output shaft rotatably installed between the power mechanism and the base, and a rotating disk fixed to one end of the output shaft.

[0006] Furthermore, the rotating disk has a groove, the inside of the groove has a discharge port, the base has an opening, and one end of the barrel is movably installed inside the opening.

[0007] Furthermore, a conical seat is fixed inside the opening, and one end of the conical seat is movably engaged with the groove.

[0008] Furthermore, a handrail is fixed on the base, a crossbar is welded between the handrails, a sleeve is rotatably installed on the crossbar, and a display screen is fixed on the sleeve.

[0009] Furthermore, a fixing bolt is rotatably installed on the side of the barrel, and a threaded hole is opened on the side of the cover plate, with one end of the fixing bolt rotatably installed inside the threaded hole.

[0010] Furthermore, a ring seat is welded to the inner wall of the barrel, the cover plate is movably mounted on the ring seat, a rotating column is mounted on the drive motor, and a conveying auger and a stirring rod are welded to the rotating column respectively.

[0011] Furthermore, the support tube has an internal cavity, the support column is movably installed inside the cavity, and a limit bolt is rotatably installed on the side of the support tube, with one end of the limit bolt movably contacting the support column.

[0012] Furthermore, a mounting bracket is fixed to the bottom of the base, and the mounting bracket is offset from the opening to the left and right. A camera is fixedly installed on the mounting bracket, and the camera is installed on the display screen via a wire.

[0013] The beneficial effects of this utility model are:

[0014] 1. This road and bridge crack reinforcement device uses a drive motor to rotate a rotating disk. The rotating disk rotates 90 degrees at a time, moving the grooves at different positions to the bottom of the opening. Different diameter discharge ports are distributed inside the grooves. The discharge ports of different diameters are rotated according to the width of the crack to inject glue, avoiding the waste caused by glue overflowing outside the crack.

[0015] 2. In this road and bridge crack reinforcement device, after the injection is completed, the rotating disc drives the used groove and discharge port to one end of the base, and the groove protrudes outside the base, which facilitates the scraping and cleaning of the glue adhering inside the groove and discharge port.

[0016] 3. After use, the barrel is removed from the support pipe by the support column. After removal, the inner wall of the barrel is cleaned separately. In addition, during use, the camera observes the direction and shape of the crack from the bottom, which makes it easy to change the position of the discharge port and complete the glue injection construction according to the direction of the crack.

[0017] 4. This road and bridge crack reinforcement device uses a drive motor to reverse the conveying auger, which in turn causes the bottom material to tumble upwards. While tumbling, the material is stirred by a stirring rod. Later, the conveying auger rotates forward, pushing the material downwards for discharge. A heating plate is fixed inside the barrel to keep the material warm and effectively prevent solidification. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5This utility model provides a technical solution: a road and bridge crack reinforcement device, including a base 1, a support seat 2 fixed to the bottom of the base 1, a caster wheel 3 fixedly installed at the bottom of the support seat 2, a support pipe 6 welded to the base 1, a support column 5 movably installed inside the support pipe 6, a barrel 4 fixed to one end of the support column 5, a cover plate 7 movably installed on the top of the barrel 4, a drive motor 9 and a feed hopper 8 fixedly installed on the cover plate 7, a power mechanism 14 fixed on the base 1, the power mechanism 14 being a DC motor, the DC motor driving a rotating disk 15 to rotate and change the position of the groove 16 and the discharge port 17. Rotate the appropriate diameter according to the width of the crack, and discharge the material through the discharge port 17 to effectively avoid the waste caused by glue overflowing outside the crack. The power mechanism 14 is rotatably installed between the base 1 and the output shaft 23. One end of the output shaft 23 is fixed with a rotating disk 15. The rotating disk 15 has a groove 16, and the discharge port 17 is opened inside the groove 16. The base 1 has an opening 26. One end of the barrel 4 is movably installed inside the opening 26. After the barrel 4 is vertically installed inside the opening 26, it is initially fixed. The barrel 4 is supported and fixed for a second time by the cooperation of the support column 5 and the support tube 6, which facilitates the quick disassembly and installation of the barrel 4 later.

[0026] In this embodiment, a conical seat 29 is fixed inside the opening 26. One end of the conical seat 29 is movably engaged with the groove 16. A handrail 11 is fixed on the base 1. A crossbar is welded between the handrails 11. A sleeve 12 is rotatably installed on the crossbar. A display screen 13 is fixed on the sleeve 12. A fixing bolt 10 is rotatably installed on the side of the barrel 4. A threaded hole 19 is opened on the side of the cover plate 7. One end of the fixing bolt 10 is rotatably installed inside the threaded hole 19. The display screen 13 displays the image captured by the camera 28. The display screen 13 displays the direction of the crack and the thickness of the grout. After grouting, the base 1 is slowly moved to perform moving grouting, ensuring that the glue fills the inside of the crack. The glue used in this device is existing asphalt liquid. The reinforcement is completed by filling the crack with asphalt liquid.

[0027] In this embodiment, a ring seat 18 is welded to the inner wall of the barrel 4, and the cover plate 7 is movably installed on the ring seat 18. A rotating column 20 is installed on the drive motor 9, and a conveying auger 21 and a stirring rod 22 are welded to the rotating column 20 respectively. A cavity 24 is opened inside the support tube 6, and the support column 5 is movably installed inside the cavity 24. A limit bolt 25 is rotatably installed on the side of the support tube 6, and one end of the limit bolt 25 is movably in contact with the support column 5. A fixing frame 27 is fixed at the bottom of the base 1. The fixing frame 27 and the opening 26 are staggered to the left and right. A camera 28 is fixedly installed on the fixing frame 27. The camera 28 is installed on the display screen 13 through a wire. The conveying auger 21 pushes the material down. The pushing of the conveying auger 21 avoids the effect caused by the slow downward flow of glue. Afterwards, the cover plate 7 drives the stirring rod 22 and the conveying auger 21 to be taken out for cleaning.

[0028] Working steps: Before use, heated asphalt liquid is injected into the barrel 4 through the feed hopper 8. The heating plate inside the barrel 4 heats the asphalt liquid to provide a suitable temperature, preventing it from solidifying inside the barrel 4. Before grouting, the position of the discharge port 17 is adjusted according to the width of the crack. The power mechanism 14 is started to drive the rotating disk 15 to rotate. The rotation of the rotating disk 15 makes the groove 16 match the bottom of the opening 26, and the material drips from the opening 26 into the groove 16, and finally drips into the crack through the discharge port 17. During the dripping of the adhesive, the dripping progress is monitored through the camera 28 and the display screen 13. After the crack is filled by dripping, the handle 11 is manually pulled to move the base 1 slowly. During the movement, the direction of the crack is monitored through the display screen 13. Screen 13 controls the direction of movement of base 1 and the position of discharge port 17. The universal wheels 3 enable the discharge port 17 to quickly adjust the direction of movement of base 1 according to the curvature of the crack. When pouring glue downwards, the drive motor 9 is started to rotate forward, and the conveying auger 21 pushes the material downwards. Under pressure, the material enters from the opening 26 into the discharge port 17 and is quickly discharged. After the equipment is used, the used groove 16 is rotated and moved to one end of base 1. The position of groove 16 is exposed outside base 1, which makes it easy to clean the inside of groove 16 and discharge port 17. The limit bolt 25 is removed, and the support column 5 is taken out vertically upwards from the inside of the support tube 6. After removal, the fixing bolt 10 is removed and the cover plate 7 is disassembled. After the cover plate 7 is disassembled, it is easy to clean the barrel 4 and the stirring rod 22, which is convenient for future reuse.
