According to the width of the road surface, the support seats 2 are slid to change the distance between the two groups of support seats 2 so that the two groups of support seats 2 are respectively close to the two sides of the road surface, reducing the unnecessary stroke of the connecting member 7 and improving the efficiency of the hydraulic pump 62 in compacting and leveling the road surface. Starting the hydraulic pump 62 can drive the pressure plate 63 to press the soil base downward. Driven by the connecting member 7, the hydraulic pump 62 can slide along the I-beam 1 to compact and level the same straight line area in the width direction of the road surface, and then move the device along the length direction of the road surface until the entire road surface is compacted and leveled.

[0028] like Figure 4 and Figure 5 As shown, the upper end of the support seat 2 is fixedly connected to the cross plate 21, and an opening is opened at the upper end of one side of the support seat 2. The I-beam 1 is located inside the opening of the support seat 2. The opening of the support seat 2 is rotatably connected to the baffle 8.

The rotating shaft 92 is rotatably connected to the slide plate 93 through the limiting ring 921. The other end of the rotating shaft 92 is fixedly connected to the turntable 922. A plurality of sliding columns 931 are fixedly connected to one side of the slide plate 93, and the sliding columns 931 are slidably connected to the support seat 2. The I-beam 1 can enter the support seat 2 through the opening of the support seat 2, rotate the baffle 8 so that the baffle 8 abuts one side of the I-beam 1, pass the plug column 81 through the cross plate 21 and insert it into the baffle 8, limit the baffle 8 so that it remains in the abutment state, rotate the turntable 922 to drive the rotating shaft 92 to rotate, and the rotating shaft 92 passes through the threaded sleeve 911 and continuously moves inward, thereby pushing the sliding column 931 to move and abut the other side of the I-beam 1, fixing the support seat 2 on the I-beam 1.

[0029] like Figure 1 As shown, threaded posts 3 are fixedly connected to both ends of the upper surface of the horizontal plate 21. The roller 4 is rotatably connected to the threaded posts 3. A fixing nut 31 is provided on the upper end of the roller 4. The fixing nut 31 is threadedly connected to the threaded posts 3. The roller 4 is sleeved on each of the four threaded posts 3, and the fixing nut 31 is screwed into the threaded posts 3 to limit the position of the roller 4 and prevent it from slipping off the threaded posts 3.

[0030] like Figure 2 and Figure 3As shown, cables 41 are provided on the two rollers 4 on the same horizontal plate 21, the cables 41 are coiled around one of the rollers 4, and the ends of the cables 41 are fixed on the other roller 4. The lower ends of the two rollers 4 on one of the two groups of support seats 2 are provided with pads 5, and the connecting member 7 includes a frame 71, a long shaft 72, a connecting wheel 1 73 and a connecting wheel 2 74.

The cable 41 of the roller 4 with the pad 5 at the lower end passes around the connecting wheel 1 73, and the cable 41 of the roller 4 of the other group of support seats 2 passes around the connecting wheel 2 74. The two rollers 4 located on the same horizontal plate 21 form a group. The end of the cable 41 wound on one of the rollers 4 of one group of rollers 4 is pulled out, passed around the connecting wheel 1 73 and fixed on the other roller 4. The end of the cable 41 wound on one of the rollers 4 of the other group of rollers 4 is pulled out, passed around the connecting wheel 2 74 and fixed on the other roller 4. The roller 4 at the fixed end of the cable 41 is actively rotated, so that the cable 41 is shortened and wound around the roller 4 at the fixed end of the cable 41, so that the sliding member 6 moves to the edge position of the I-beam 1, reducing the use of the power device, reducing the cost of the device, and keeping relatively quiet during operation, reducing the impact on the construction environment.

[0031] When the cable 41 of the drum 4 at one end of the I-beam 1 is shortened, the cable 41 of the drum 4 at the other end of the I-beam 1 will be lengthened. The group of drums 4 with shortened cables 41 is actively driven, and the group of drums 4 with extended cables 41 is passively driven. When the sliding member 6 is located at one end of the I-beam 1, the length of the cable 41 pulled out of the drum 4 at the other end of the I-beam 1 is at its longest.

[0032] Adopting this utility model, such as Figure 1 and Figure 2As shown, the sliding member 6 equipped with the connecting member 7 is slidably connected to the I-beam 1, and the I-beam 1 is passed through the openings of the two groups of support seats 2 into the support seat 2.

Rotating the turntable 922 can drive the rotating shaft 92 to rotate, and the rotating shaft 92 passes through the threaded sleeve 911 and continuously moves inward, thereby pushing the sliding column 931 to move and abut the other side of the I-beam 1, fixing the support seat 2 on the I-beam 1, and can quickly adjust the structure according to the requirements of different road construction widths, and the disassembly and assembly process is simple, the detachable device is highly flexible, and has strong adaptability to working conditions. The roller 4 is sleeved on the threaded column 3 on the cross plate 21, and the fixing nut 31 is screwed into the threaded column 3 to limit the roller 4. When the roller 4 is set on one of the support seats 2, the pad 5 is first sleeved on the threaded column 3, and then the roller 4 is sleeved, which plays the role of raising the roller 4, and the cable 41 wound on the roller 4 with the pad 5 at the bottom is pulled out, bypasses the connecting wheel 1 73 and is fixed to the other roller 4 on the same side, and the cable 41 wound on the roller 4 on the other side is pulled out, bypasses the connecting wheel 2 74 and is fixed to the other roller 4 on the same side, and the roller 4 at one end of the I-beam 1 is rotated to shorten the cable 41 extending from the end, thereby causing the sliding member 6 to move toward the end. By repeatedly rotating the rollers 4 at both ends in sequence, the pressure plate 63 on the hydraulic pump 62 compacts and levels the same straight line area in the width direction of the road surface, and then moves the device along the length direction of the road surface until the entire road surface is compacted and leveled, reducing the use of power devices and reducing the cost of the device.
