[0038] This invention proposes a maintenance compaction device, comprising: a compaction vehicle 1, an angle adjustment frame 2, a connecting frame 3, a semi-circular clamping cylinder 4, and a compaction cylinder 5; the lower end of the angle adjustment frame 2 is rotatably connected to the front bottom of the compaction vehicle 1, and an outer connecting frame 201 is fixed to the middle of the outer sides of the two vertical channel steels of the angle adjustment frame 2, and a T-shaped insertion port 202 is provided in the middle of the front side of the two vertical channel steels of the angle adjustment frame 2; two sets of angle adjustment cylinders 101 are installed on the front side of the compaction vehicle 1, and the rear end of the angle adjustment cylinder 101 is rotatably connected to the frame of the compaction vehicle 1, and the telescopic ends are rotatably connected to the outer connecting frame 201; the connecting frame 3 is welded to the two vertical channel steels of the angle adjustment frame 2 through two sets of insert plates 301 fixed in the middle of its rear side, passing through the insertion port 202; the upper and lower ends of the connecting frame 3 are respectively provided with adjustment grooves 302, and a drive shaft 303 is movably inserted into the upper adjustment groove 302, and the lower adjustment groove 302 is rotatably inserted into the lower adjustment groove 302. A linkage shaft 305 is movably inserted into the groove 302. Three sets of chain assemblies 309 are installed between the drive shaft 303 and the linkage shaft 305. The sprockets of the three sets of chain assemblies 309 are respectively keyed to the drive shaft 303 and the linkage shaft 305. Rotary lifting blocks 3091 are fixed at the diagonally opposite positions of the three sets of chain assemblies 309. A mounting bracket 306 is also provided on the upper side of the connecting frame 3. The front end of the mounting bracket 306 is movably fitted onto the drive shaft 303. A drive motor 307 is also fixed on the mounting bracket 306. The motor shaft of the drive motor 307 is connected to the drive shaft 303 through bevel gear transmission. There are two sets of semi-circular clamping cylinders 4. The two sets of semi-circular clamping cylinders 4 are installed opposite each other at the front ends of the connecting frame 3. The compaction cylinder 5 is slidably clamped in the two sets of opposite semi-circular clamping cylinders 4. The top of the compaction cylinder 5 is also provided with a filling port 503, which is plugged with a rubber stopper.

[0039] like Figure 8 As shown, height adjustment cylinders 304 are installed on the outer sides of both ends of the connecting frame 3. The top of the telescopic end of the height adjustment cylinder 304 is respectively fitted onto the outer end of the drive shaft 303. A horizontal plate is connected between the two sets of insert plates 301, and a set of height adjustment cylinders 308 is fixed on the horizontal plate. The top of the telescopic end of the height adjustment cylinder 308 is fixedly connected to the mounting frame 306. The height adjustment cylinder 308 is located directly below the drive motor 307. The two sets of height adjustment cylinders 304 and the two sets of height adjustment cylinders 308 move synchronously. By controlling the synchronous movement of the two sets of height adjustment cylinders 304 and the two sets of height adjustment cylinders 308, the height of the drive shaft 303, the linkage shaft 305, the three sets of chain assemblies 309, the mounting frame 306, and the drive motor 307 are adjusted, thereby changing the height of the tamping cylinder 5 and adjusting the tamping force when the tamping cylinder 5 falls.

[0040] like Figure 2 and Figure 8As shown, two sets of pulleys 3061 are installed on both ends of the mounting frame 306, and the pulleys 3061 are attached to the vertical channel steel inside the angle adjustment frame 2. When adjusting the height of the mounting frame 306, the pulleys 3061 on both sides of the mounting frame 306 contact the inner wall of the vertical channel steel inside the angle adjustment frame 2 to improve the smoothness of the mounting frame 306 when adjusting up and down.

[0041] like Figure 2 and Figure 6 As shown, two sets of U-shaped frames 401 are welded to the back side of the semi-circular clamp 4, and the U-shaped frames 401 are inserted into the inner side plate of the connecting frame 3 and fixed by through bolts, which facilitates the connection and disassembly of the semi-circular clamp 4 and the connecting frame 3.

[0042] like Figure 5 and Figure 9 As shown, the left and right ends of the compaction cylinder 5 are semi-circular structures, each equipped with five vertical rows of pulleys 501. The pulleys 501 are attached to the inner walls of the two sets of semi-circular clamping cylinders 4. The bottom of the compaction cylinder 5 has arc-shaped structures on both the front and rear sides. Three sets of fixed lifting blocks 502 are welded to the lower rear end of the compaction cylinder 5. During the rotation of the chain assembly 309, the rotating lifting blocks 3091 contact the bottom of the fixed lifting blocks 502 from below. The pulleys 501 allow the compaction cylinder 5 to... The compaction cylinder 5 is positioned within two sets of opposing semi-circular cylinders 4, which increases the smoothness of the compaction cylinder 5 as it slides up and down within the two sets of opposing semi-circular cylinders 4. When the three sets of chain assemblies 309 are activated, the rotating lifting block 3091 contacts the bottom of the fixed lifting block 502 from below, pushing the compaction cylinder 5 up from the two sets of opposing semi-circular cylinders 4. When the rotating lifting block 3091 disengages from the bottom of the fixed lifting block 502, the compaction cylinder 5 falls within the two sets of semi-circular cylinders 4 to compact the road maintenance section.

[0043] The specific usage and function of this embodiment: In this invention, firstly, when the drive motor 307 drives the drive shaft 303 to rotate, it drives the three sets of chain assemblies 309 to move, causing the rotating lifting block 3091 to contact the bottom of the fixed lifting block 502 from the lower side, pushing the compaction cylinder 5 from the two sets of opposing semi-circular clamps 4, so that the bottom of the compaction cylinder 5 leaves the ground. Then, the compaction vehicle 1 is driven to the road maintenance section, and water is added to the compaction cylinder 5 by pulling out the rubber plug in the filling port 503, increasing the weight of the compaction cylinder 5. The amount of water added can be changed according to the required compaction force, thereby adjusting the compaction cylinder 5 to the corresponding weight. Then, by controlling the synchronous operation of the two sets of height adjustment cylinders 304 and the two sets of height adjustment cylinders 308, the drive shaft 303, the linkage shaft 305, the three sets of chain assemblies 309, and the safety device are adjusted. The height of the mounting frame 306 and the drive motor 307 changes the height of the tamping cylinder 5, thereby adjusting the tamping force when the tamping cylinder 5 falls. The bottom of the angle adjustment frame 2 is rotatably connected to the bottom of the tamping vehicle 1, and the telescopic end of the angle adjustment cylinder 101 is connected to the outer connecting frame 201. By controlling the angle adjustment cylinder 101, the tilt angle of the angle adjustment frame 2 is changed, thereby changing the tilt angle of the connecting frame 3, the semi-circular clamping cylinder 4, and the tamping cylinder 5, thus adjusting the contact area between the tamping cylinder 5 and the ground, and changing the width of the tamping surface of the road maintenance section. When the drive motor 307 drives the drive shaft 303 to rotate, it drives the three sets of chain assemblies 309 to move, causing the rotating lifting block 3091 to disengage from the bottom of the fixed lifting block 502, so that the tamping cylinder 5 falls in the two sets of semi-circular clamping cylinders 4 to tampe the road maintenance section.
