Description

Technical Field

[0001] This utility model specifically relates to a joint filling device for road and bridge construction, belonging to the technical field of joint filling devices. Background Technology

[0002] Road surface cracks are one of the most common and easily occurring early-stage defects among various types of road surface damage. They accompany the road surface for almost its entire service life and worsen with increasing road age. Road surface cracks not only affect the aesthetics of the road and the comfort of driving, but also easily expand into structural damage to the road surface, shortening its service life.

[0003] Currently, during road and bridge construction, it is often necessary to fill road gaps. The size and shape of road gaps vary. Existing equipment mostly uses asphalt grouting machines for operation. However, existing equipment can only discharge the heated and softened asphalt at the end, without treating the dust in the gaps. This causes the asphalt to adhere to the debris in the gaps, affecting the adhesion between the asphalt and the road surface gap walls, and easily leading to asphalt blocks falling off after filling. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a road and bridge construction joint filling device to achieve the purpose of cleaning debris from the joints.

[0005] A road and bridge construction joint filling device includes a platform, a filling component installed on the top of the platform, and an adjustment component. The side of the adjustment component is connected to the side of the filling component. The adjustment component includes a support frame, the end of the support frame is fixedly connected to the side of the filling component, a fixing ring is fixedly connected to the end of the support frame, a rotating shaft is rotatably connected to the inner wall of the fixing ring, a roller is installed at the bottom of the rotating shaft, a rotating tooth is installed at the top of the roller, and an adjustment tooth is engaged on the side of the rotating tooth through tooth meshing.

[0006] The cleaning component connects to the side of the filling component, and the cleaning component can clean debris from the gaps.

[0007] Furthermore, the overall structure of the rotating shaft is arranged at right angles to the support frame, and the rollers are placed in the cracks in the ground during use. The rollers are designed to be detachable.

[0008] Furthermore, the cleaning component includes a blower tube, the side of which is connected to the side of the filling component. The blower tube is fixedly connected to the back of the adjusting tooth relative to the rotating tooth. A connecting ring is fixedly connected to the end of the blower tube. An adjusting rod is slidably connected inside the connecting ring. An adjusting plate is hinged to the end of the adjusting rod. The end of the adjusting plate is rotatably connected to the inner wall of the blower tube.

[0009] Furthermore, a movable ring is slidably connected to the outer edge of the blower tube, and several sets of telescopic springs are installed in the gap between the movable ring and the connecting ring. The telescopic springs are sleeved on the outside of the adjusting rod. A pull rope is installed on the top of the movable ring. A motor is fixedly connected to the inner wall of the blower tube through a bracket, and a fan blade is fixedly connected to the output end of the motor.

[0010] Furthermore, the adjusting plate is designed as a tile structure, and multiple sets of adjusting plates can be bonded together to form a ring structure.

[0011] Furthermore, the filling component includes a liquid-gas tank, the bottom of which is connected to the top of the platform. A combustion rack is connected to the side of the liquid-gas tank via a conduit. A canister is placed on top of the combustion rack. A transfer pipe is connected to the side of the canister, and a filling gun is installed at the output end of the transfer pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a road and bridge construction joint filling device includes a platform 1, a filling component 2 installed on the top of the platform 1, and an adjustment component 3. The side of the adjustment component 3 is connected to the side of the filling component 2. The adjustment component 3 includes a support frame 10. The end of the support frame 10 is fixedly connected to the side of the filling component 2. A fixing ring 11 is fixedly connected to the end of the support frame 10. A rotating shaft 12 is rotatably connected to the inner wall of the fixing ring 11. A roller 13 is installed at the bottom of the rotating shaft 12. A rotating tooth 14 is installed at the top of the roller 13. An adjustment tooth 15 is engaged on the side of the rotating tooth 14 through tooth meshing.

[0024] Cleaning component 4, the side of cleaning component 4 is connected to the side of filling component 2, cleaning component 4 can clean debris in the gap.

[0025] During the asphalt paving process, the operator holds the filling gun 9 and places its end on the road surface crack. Then, the roller 13 at the bottom of the adjusting component 3 is placed into the crack. The operator then moves the entire equipment along the crack direction, and the roller 13 is embedded in the crack. The curvature of the road surface crack will cause the roller 13 and the rotating shaft 12 to rotate together. At the same time, the support frame 10 connected to the side of the fixing ring 11 is fixed to the filling gun 9, so that the rotating shaft 12 rotates on the inner wall of the fixing ring 11. Meanwhile, the rotation of the rotating teeth 14 causes the adjusting teeth 15 and the air blowing pipe 16 to deflect, so that the air blowing direction of the motor 23 and the fan blades 24 inside the air blowing pipe 16 is consistent with the curvature of the road surface crack, ensuring the accuracy of air blowing and cleaning the debris in the crack.

[0026] As a technical optimization of this utility model, the overall structure of the rotating shaft 12 is arranged at right angles with the support frame 10. The roller 13 is placed at the crack in the ground during use. The roller 13 is designed to be detachable. The roller 13 can be selected according to the size of the gap so that the roller 13 can be embedded in the gap.

[0027] As a technical optimization of this utility model, the cleaning component 4 includes a blower pipe 16. The side of the blower pipe 16 is rotatably connected to the side of the filling gun 9 inside the filling component 2. The side of the blower pipe 16 is fixedly connected to the back of the adjusting tooth 15 relative to the rotating tooth 14. A connecting ring 17 is fixedly connected to the end of the blower pipe 16. An adjusting rod 18 is slidably connected inside the connecting ring 17. An adjusting plate 19 is hinged to the end of the adjusting rod 18. The end of the adjusting plate 19 is rotatably connected to the inner wall of the blower pipe 16. When it is necessary to control the airflow range at the port of the blower pipe 16, the airflow range is adjusted in real time according to the width of the gap. The operator manually pulls the pull rope 22. The movable ring 20 at the end of the pull rope 22 moves up along the surface of the connecting ring 17, and the end of the adjusting plate 19 connected to the adjusting rod 18 is pulled to it, so that the adjusting plate 19 is in an expanded state. This allows control over the range of airflow discharged from the blower pipe 16, blowing a large area towards the wide gap. At the same time, in the original state, if the person does not pull the pull rope 22, the elastic force of the telescopic spring 21 will pull the movable ring 20 down, and the adjusting rod 18 and the adjusting plate 19 connected to the movable ring 20 will be in a retracted state. This causes the airflow from the blower pipe 16 to concentrate on the narrow gap, making the process of blowing away impurities more effective and achieving the effect of dynamically adjusting the blowing range according to the gap width.

[0028] As a technical optimization of this utility model, a movable ring 20 is slidably connected to the outer edge of the blower pipe 16. Several sets of telescopic springs 21 are installed in the gap between the movable ring 20 and the connecting ring 17, and the telescopic springs 21 are sleeved on the outside of the adjusting rod 18. A pull rope 22 is installed on the top of the movable ring 20. A motor 23 is fixedly connected to the inner wall of the blower pipe 16 through a bracket. A fan blade 24 is fixedly connected to the output end of the motor 23. The arrangement of the motor 23 and the fan blade 24 can make the bottom end of the blower pipe 16 present a blowing state. At the same time, the displacement change of the end of the adjusting rod 18 can control the adjusting plate 19 connected to it to directly expand or retract, thereby controlling the range adjustment of the overall air blowing of the cleaning component 4.

[0029] As a technical optimization of this utility model, the adjusting plate 19 is set as a tile structure, and multiple sets of adjusting plates 19 can be attached to form a ring structure. The setting of the adjusting plate 19 can limit the size of the opening of the blower pipe 16 after blowing air, thereby adjusting the airflow area blown into the gap.

[0030] As a technical optimization of this utility model, the filling component 2 includes a liquid-gas tank 5. The bottom end of the liquid-gas tank 5 is connected to the top of the platform 1. The side of the liquid-gas tank 5 is connected to a combustion frame 6 through a conduit. A canister 7 is placed on the top of the combustion frame 6. A transmission pipe 8 is connected to the side of the canister 7. A filling gun 9 is installed at the output end of the transmission pipe 8. The liquid-gas tank 5 is injected into the combustion frame 6 through the pipe for combustion, which then heats the asphalt inside the canister 7. The asphalt is then transmitted to the filling gun 9 through the transmission pipe 8. The bottom end of the filling gun 9 can discharge the flowing hot asphalt into the road surface cracks, thereby filling the road surface cracks.

[0031] As a technical optimization of this utility model, the tank 7 is filled with asphalt, and the tank 7 is filled with a stirring structure. The stirring structure is equipped with a drive motor and a stirring blade connected to the output shaft of the drive motor. The stirring blade can mix the asphalt.
