DETAILED DESCRIPTION
[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.
[0018] This embodiment includes an inverted U-shaped steel plate 1, which can be made of channel steel commonly used on construction sites. Two ramming columns 3 are connected to the opening below the inverted U-shaped steel plate 1, and the inverted U-shaped steel plate 1 and the two ramming columns 3 form a door shape. Strip holes 2 are symmetrically provided on the two side panels of the inverted U-shaped steel plate 1. In this embodiment, the strip holes 2 on each side panel are set as two upper and lower strips. The two ramming columns 3 are symmetrically arranged inside the inverted U-shaped steel plate 1. The ramming columns 3 are rectangular parallelepipeds. The width of the ramming columns 3 is equal to the inner width of the inverted U-shaped steel plate 1. The ramming columns 3 are located between the two side panels of the inverted U-shaped steel plate 1. A horizontal ramming plate 4 is fixed at the bottom end of the ramming column 3. The ramming plate 4 is a rectangular plate. The long screw 5 passes vertically through the strip hole 2 and the ramming column 3, and the position where the long screw 5 contacts the ramming column 3 is welded together to prevent the ramming column 3 from swinging left and right around the long screw 5, but the long screw 5 can slide left and right along the strip hole 2. Nuts 6 are installed at both ends of the long screw 5, securing the tamping posts 3 to the inverted U-shaped steel plate 1. A rubber gasket 12 can be placed over the long screw 5 to further secure the nuts 6 to the long screw 5. The position of the tamping posts 3 is adjusted by sliding the long screw 5 within the slot 2, thereby adjusting the spacing between the two tamping posts 3 and the two tamping plates 4, so that the two tamping posts 3 and the two tamping plates 4 are positioned on opposite sides of the pipe. To prevent the tamping posts 3 from accidentally touching the pipe and causing damage, a rubber pad 10 is preferably installed on the inner side of the tamping posts 3, which faces the side of the pipe.
[0019] A vibration device 7 for tamping is installed in the middle of the upper surface of the inverted U-shaped steel plate 1. Two connecting plates 8 are symmetrically provided on both sides of the vibration device 7. The connecting plates 8 are provided with connecting holes 9. The connecting plates 8 are used to connect to the excavator. The connecting plates 8 are connected to the excavator by passing through the connecting holes 9 of the connecting plates 8 and the pin shaft seat of the excavator boom. Conventional excavator booms are provided with a pin shaft seat, and the bucket can be connected to the excavator boom by passing through the pin shaft seat. The two connecting plates 8 of the present invention correspond to the pin shaft seat of the excavator boom. The bucket of the excavator can be removed and connected to the device of the present invention. The excavator bucket connection structure is a well-known structure. In this embodiment, the bucket is simply replaced with a device for connecting the present invention, which will not be repeated here. In order to make the device more stable, a stiffening rib 11 is preferably provided between the connecting plate 8 and the inverted U-shaped steel plate 1.
[0020] To use the small trench pipe compaction tool, the device is connected to a small excavator via a connecting plate 8. Adjusting the device to a suitable angle allows the excavator to move the device. After measuring the trench width and pipe diameter, the two tamping posts 3 are adjusted by sliding a long screw 5 through the slots 2, ensuring that the two tamping plates 4 are positioned close to the pipe on either side. Nuts 6 are then tightened to secure the tamping posts 3. Finally, the vibrating device 7 is activated to begin compaction.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
