Description

Technical Field

[0001] This utility model belongs to the technical field of compaction devices, and relates to a compaction device for ductile iron pipes, especially a compaction device for laying ductile iron pipes. Background Technology

[0002] After laying ductile iron pipes, backfilling and compaction of the soil are often required to ensure the safety of the pipes. For compaction of small areas, plate compactors are usually used. However, the compaction area of ​​such equipment is fixed and cannot be adjusted according to practical needs. Therefore, when facing the compaction requirements of laying large-diameter ductile iron pipes, the compaction width is often insufficient, which leads to repeated adjustments to the position for compaction, resulting in slow construction speed and poor effect.

[0003] To address this issue, we propose a compaction device for laying ductile iron pipes. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a compaction device for laying ductile iron pipes that is simple in structure and easy to use.

[0005] To solve the above problems, the technical solution of this utility model is as follows:

[0006] A compaction device for laying ductile iron pipes, comprising:

[0007] The base plate has a tamping plate installed at the bottom end, and the engine and vibration components are also fixedly installed on the base plate, which is suitable for tamping operations.

[0008] A rotating component is installed between the base plate and the compaction plate, and the compaction area is adjusted by rotating the compaction plate.

[0009] A pair of movable components are fixedly installed at both ends of the base plate, which are suitable for moving the base plate and adjusting the height of the base plate.

[0010] In a further embodiment, the vibration assembly includes an eccentric block and a drive belt, one end of which is rotatably mounted on a base plate, and the other end of which is connected to the engine via the drive belt.

[0011] In a further embodiment, one side of the eccentric block has a protrusion adapted to generate vibration during rotation.

[0012] In a further embodiment, the rotating assembly includes a drive shaft, a reducer, and a motor. The motor is mounted at the input end of the reducer, the top end of the drive shaft is mounted at the output end of the reducer, and a tamping plate is fixedly mounted at the bottom end of the drive shaft.

[0013] In a further embodiment, both the speed reducer and the motor are fixedly mounted on the base plate.

[0014] In a further embodiment, the top end of the drive shaft is rotatably mounted inside the base plate via a bearing.

[0015] In a further embodiment, the moving assembly includes an extension rod, a telescopic rod, a pair of rollers, and a crossbar. One end of the extension rod is fixedly mounted on a base plate, and the other end of the extension rod is fixedly mounted on a telescopic rod. The bottom end of the telescopic rod is fixedly mounted on a crossbar, and the rollers are rotatably mounted on both ends of the crossbar.

[0016] In a further embodiment, a protective cover is fixedly installed on one side of the eccentric block, the drive belt, and the engine.

[0017] In a further embodiment, the fuel tank and battery are fixedly mounted on the base plate.

[0018] In a further embodiment, a handle is also fixedly installed on the base plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The compaction device has a compaction plate installed under the base plate via a rotating device. Movable components are fixedly installed at the front and rear ends of the base plate. The movable components can extend and retract. When the movable components extend, the rollers of the movable components contact the ground, and the base plate is lifted upward, driving the compaction plate away from the ground. This not only propels the device to move, but also allows the lateral coverage area of ​​the compaction plate to be adjusted by rotating the compaction plate via the rotating device. The compaction area can be adjusted according to the compaction requirements, making it widely applicable.

[0021] 2. The engine and vibration assembly are fixedly installed on the base plate of this compaction device. A protective cover is fixedly installed on the outside of the vibration assembly to protect the stable operation of the vibration assembly. The vibration assembly includes an eccentric block and a transmission belt. One end of the eccentric block is rotatably mounted on the base plate, and the other end of the eccentric block is connected to the output shaft of the engine through the transmission belt. The eccentric block has a cylindrical structure and a protrusion on one side, so that the eccentric block can generate vibration when it rotates at high speed, thereby driving the compaction plate to perform the compaction operation.

[0027] Example 1:

[0028] A compaction device for laying ductile iron pipes, such as Figures 1 to 3 As shown, the system includes a base plate 7 and a compaction plate 6. The compaction plate 6 is rotatably mounted on the bottom end of the base plate 7 via a rotating assembly 10. Moving assemblies 5 are fixedly mounted on the front and rear ends of the base plate 7, respectively. The moving assemblies 5 can move up and down. When the moving assemblies 5 move downwards, they lift the base plate 7, moving the compaction plate 6 away from the ground, allowing for rotation. When the moving assemblies 5 move upwards, they lower the base plate 7, bringing the compaction plate 6 into contact with the ground for compaction. Preferably, the compaction plate 6 has a rectangular structure, which allows for changing the lateral coverage area of ​​the compaction plate 6 through rotation.

[0029] like Figures 1 to 3As shown, a tilted handle 3 is fixedly installed at the rear end of the base plate 7. The handle 3 has a U-shaped structure, which is suitable for pushing the compaction device to move. An oil tank 1, an engine 2, a battery 4, and a vibration assembly 9 are also fixedly installed on the base plate 7. The oil tank 1 is fixedly installed at the front end of the base plate 7, and the engine 2 is fixedly installed in the middle of the base plate 7. The oil tank 1 is connected to the interior of the engine 2, which is suitable for supplying oil to the engine 2. The battery 4 is fixedly installed at the rear end of the base plate 7. The battery 4 is connected to the engine 2, the moving assembly 5, the rotating assembly 10, and other structures, which is suitable for supplying power. One end of the vibration assembly 9 is rotatably installed on the base plate 7, and the other end of the vibration assembly 9 is connected to the engine 2. A protective cover 8 is also fixedly installed on the outside of the vibration assembly 9. The vibration assembly 9 includes an eccentric block 91 and a transmission belt 92. The eccentric block 91 is located below the oil tank 1 and is fixedly mounted on a shaft. One end of the shaft is rotatably mounted on the base plate 7, and the other end of the shaft is connected to the output shaft of the engine 2 via the transmission belt 92, so that the engine 2 drives the eccentric block 91 to rotate. The eccentric block 91 has a near-cylindrical structure, and one side of the eccentric block 91 has a protruding fan-shaped structure, so that the eccentric block 91 can generate vibration when rotating at high speed, thereby driving the compaction device to compact.

[0030] like Figure 3 As shown, the rotating assembly 10 includes a drive shaft 101, a reducer 102, and a motor 103. The reducer 102 and the motor 103 are fixedly mounted on the base plate 7. The top end of the drive shaft 101 is rotatably mounted on the middle of the base plate 7 via a bearing. The input end of the reducer 102 is connected to the output end of the motor 103, and the output end of the reducer 102 is connected to the top end of the drive shaft 101. The bottom end of the drive shaft 101 is fixedly mounted on the compaction plate 6. Preferably, the reducer 102 is a worm gear reducer, which can reduce the rotational speed of the motor 103 and output it to the drive shaft 101 to drive the compaction plate 6 to rotate.

[0031] like Figure 1 As shown, the movable component 5 includes an extension rod 51, a telescopic rod 52, a pair of rollers 53, and a crossbar 54. One end of the extension rod 51 is fixedly mounted on the base plate 7, and the other end of the extension rod 51 has an annular structure, which is fitted onto the outer side of the middle of the telescopic rod 52. The bottom end of the telescopic rod 52 is fixedly mounted on the middle of the crossbar 54, and rollers 53 are rotatably mounted on both ends of the crossbar 54. Preferably, the telescopic rod 52 is an electric push rod. When the electric push rod extends downward, the pair of rollers 53 contact the ground, which is suitable for moving and loading, and can support the base plate 7, so that the compaction plate 6 is away from the ground, making it easier to rotate the compaction plate 6 to adjust the compaction area. When the electric push rod retracts, the pair of rollers 53 move away from the ground, so that the base plate 7 is lowered, causing the compaction plate 6 to contact the ground, which is suitable for compaction operations.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
