Description
Technical Field
[0001] This utility model belongs to the field of expansion joint construction technology, specifically a road expansion joint construction device. Background Technology
[0002] An expansion joint is a structural joint installed at appropriate locations along the road to prevent cracks or damage to the road structure caused by changes in climate and temperature (thermal expansion and contraction). An expansion joint divides the road into two independent sections, allowing for horizontal expansion and contraction along its length.
[0003] A search revealed that patent CN220079679U discloses a cleaning device for cutting expansion joints, comprising a movable wheel plate. A cutting device is fixedly installed on the top of the movable wheel plate, and the cutting blade of the cutting device passes through the bottom of the movable wheel plate. A dust collection box is fixedly installed on the top of the movable wheel plate, and an L-shaped pipe is connected to the left side of the dust collection box. This invention utilizes a fan to create negative pressure inside the dust collection box. This negative pressure is generated at the suction head through the L-shaped pipe and corrugated telescopic pipe. A motor drives a threaded rod to rotate, which in turn moves the suction head up and down via a U-shaped frame and a vertical pole to adjust its height, ensuring the suction nozzle is as close to the ground as possible. The cutting blade on the cutting device cuts the ground, and the resulting debris is sucked into the dust collection box through the corrugated telescopic pipe and L-shaped pipe by the suction at the suction head. This achieves the goal of collecting debris simultaneously with cutting, reducing manual labor.
[0004] Analysis of the above technical solutions reveals that, due to the splashing of debris generated during cutting, larger debris ejects from the inner wall of the suction head, making it difficult to collect some of the debris. Furthermore, relying solely on the suction power of the suction head is insufficient to pick up larger particles, leading to a continuous accumulation of debris at the suction head and thus reducing the effectiveness of debris collection during expansion joint cutting. Therefore, we provide a road expansion joint construction device to solve these problems. Utility Model Content

[0021] 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.
[0022] Example 1, such as Figure 1-5As shown, this embodiment proposes a road expansion joint construction device, including a vehicle body 1. A fixing frame 2 and a dust collection box 8 are fixedly connected to the vehicle body 1. The fixing frame 2 is located at the left end of the vehicle body 1. The dust collection box 8 is a mature existing technology. A filter bag is installed inside the dust collection box 8. A dust extraction pipe 7 is connected to the side of the dust collection box 8 through a vacuum cleaner. The bottom end of the dust extraction pipe 7 is connected to a chip collection mechanism, which is movably installed on the bottom surface of the vehicle body 1. A chip sweeping mechanism is installed on the left side of the chip collection mechanism and is raised and lowered on the vehicle body 1. A cutting component 4 is installed on the fixing frame 2. With the above structure, when the cutting component 4 cuts the expansion joint of the road surface, the debris generated during the cutting process will be extracted into the chip collection mechanism by the vacuum cleaner. Large particles of debris are retained in the chip collection mechanism for subsequent unified processing, while dust is drawn into the dust collection box 8 through the dust extraction pipe 7, thus more comprehensively cleaning the debris generated during cutting. With the chip sweeping mechanism set up, when the cutting component 4 is working, the chip sweeping mechanism rises upwards without affecting the dust collection effect of the chip collection mechanism. After the cutting component 4 finishes working, the chip sweeping mechanism can be controlled to descend and sweep the debris on the left side of the chip collection mechanism, thereby sweeping it into the chip collection mechanism, eliminating the need for personnel to re-process it with tools. The machinery, parts and equipment in this device all adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.
[0023] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:
[0024] like Figure 1 As shown, the chip collection mechanism includes two upright plates 10, the top ends of which are fixed to the bottom surface of the vehicle body 1. A dust collection frame 11 is hinged between the bottom ends of the two upright plates 10, allowing the dust collection frame 11 to swing between the two upright plates 10. The bottom end of the dust extraction pipe 7 passes through the vehicle body 1 and is connected to the dust collection frame 11. A spring 19 is fixed to the dust collection frame 11. The dust extraction pipe 7 is a flexible hose, so it can swing with the dust collection frame 11. The top end of the spring 19 is fixed to the bottom surface of the vehicle body 1. A chip collection hopper 16 is slidably arranged inside the dust collection frame 11, through which the chip collection hopper 16 can collect chips. Large debris is collected, and the inner top wall of the dust collection frame 11 can also prevent debris from being ejected. The bottom surface of the dust collection frame 11 is rotatably connected to two moving wheels 15, allowing the dust collection frame 11 to move on the ground via the two moving wheels 15. With the above structure, when the cutting component 4 cuts the expansion joint on the ground, the operation of the vacuum cleaner will draw dust and debris into the dust collection frame 11, so that larger debris will be collected into the debris collection hopper 16, preventing debris entering the dust collection frame 11 from falling to the outside, while dust will enter the dust collection box 8 through the dust extraction pipe 7 for dust collection treatment.
[0025] like Figure 3 and Figure 5 As shown, a limiting groove 9 is provided on the vehicle body 1, and a pull rod 14 is slidably arranged in the limiting groove 9. A support block 23 and a limiting block 22 are fixedly connected to the surface of the pull rod 14. The support block 23 is in close contact with the upper surface of the vehicle body 1, and the limiting block 22 is located on the bottom surface of the vehicle body 1 and is adapted to the limiting groove 9. The bottom end of the pull rod 14 is rotatably connected to a base plate 21, and a connecting rod 20 is hinged to the bottom surface of the base plate 21. The bottom end of the connecting rod 20 is hinged to the vehicle body 1. With the above structure, after the dust collection frame 11 is used, it can be manually... Pulling the lever 14 upwards pulls the limiting block 22 to the top of the vehicle body 1. At this time, the connecting rod 20 will pull the vacuum frame 11 to swing upwards, so that the right end of the vacuum frame 11 can swing around the two upright plates 10, thereby moving the left side of the vacuum frame 11 away from the bottom surface and preventing the vacuum frame 11 from continuously contacting the ground. Then, the lever 14 is rotated to make the limiting block 22 stick tightly to the upper surface of the vehicle body 1, limiting and fixing the lever 14. When the vacuum frame 11 moves with the vehicle body 1, the moving wheel 15 can move on the ground.
[0026] like Figures 1 to 4 As shown, the dust removal mechanism includes a U-shaped plate 12 and a mounting frame 17. The U-shaped plate 12 is fixed to the vehicle body 1. Two cylinders 13 are installed on the U-shaped plate 12. The telescopic end of each cylinder 13 is connected to the top of the mounting frame 17. A cleaning brush 18 is rotatably connected to the inner wall of the mounting frame 17. A motor 24 that drives the cleaning brush 18 to rotate is installed on the front of the mounting frame 17. The cleaning brush 18 is located on the left side of the dust collection frame 11. With the above structure, after the cutting component 4 completes the cutting of the expansion joint on the ground, the cylinder 13 can drive the mounting frame 17 to move downward and start the motor 24 to drive the cleaning brush 18 to rotate counterclockwise. This will sweep the debris accumulated on the left side of the dust collection frame 11 into the dust collection hopper 16, eliminating the need for manual cleaning of the debris on the left side of the dust collection frame 11. When the cutting component 4 cuts the expansion joint on the ground, the cleaning brush 18 will move upward, which will not prevent the debris and dust from entering the dust collection frame 11.
[0027] like Figure 1 and Figure 2 As shown, a scale plate 5 is fixedly connected to the fixed frame 2, and an indicator plate 6 is fixedly connected to the cutting assembly 4. The top of the indicator plate 6 passes through the fixed frame 2 and corresponds to the scale plate 5. With the setting of the scale plate 5 and the indicator plate 6, when the cutting assembly 4 moves below the fixed frame 2, the indicator plate 6 moves up and down on the fixed frame 2, making it easy for personnel to observe the position of the top of the indicator plate 6 on the scale plate 5. This helps personnel to know the cutting depth of the cutting assembly 4 and thus makes it easier to control the lifting and lowering of the cutting assembly 4.
[0028] like Figure 1 and Figure 2As shown, two opposing guide slots are provided on the vehicle body 1, and a protective cover 3 is slidably installed on the vehicle body 1 through the two guide slots. The protective cover 3 can shield and protect the components on the vehicle body 1 to avoid collision damage. The protective cover 3 can slide freely on the vehicle body 1 and will not affect the operation of personnel on the vehicle body 1.
[0029] The working principle and usage process of this utility model are as follows: When the cutting component 4 cuts the expansion joint on the ground, the vacuum cleaner will draw dust and debris into the vacuum frame 11, so that larger debris will be collected into the debris collection hopper 16. The debris that enters the vacuum frame 11 will not be ejected, thus preventing the debris that enters the vacuum frame 11 from falling to the outside. The dust will enter the dust collection box 8 through the dust extraction pipe 7 for dust collection. After the cutting component 4 finishes its work, the cylinder 13 can drive the mounting bracket 17 to move downwards, and the motor 24 can be started to drive the cleaning brush 18 to rotate counterclockwise, so that the debris accumulated on the left side of the vacuum frame 11 can be swept into the debris collection hopper 16. There is no need for personnel to manually clean the debris on the left side of the vacuum frame 11. When the cutting component 4 cuts the expansion joint on the ground, the cleaning brush 18 will move upwards, which will not prevent debris and dust from entering the vacuum frame 11.
