[0002] In the field of electric power engineering, the stable installation of power poles is crucial for ensuring the safety and reliability of power transmission. The stability of power poles largely depends on the quality of the ramming of the pole pit. However, traditional methods and equipment for ramming the pole pit in electric power engineering have many problems.

[0003] Most traditional pole pit ramming devices for electric power engineering use fixed structure ramming hammers, whose diameters cannot be adjusted according to the actual size of the pole pit. In actual construction, different specifications of power poles require different diameters of pole pits. Fixed diameter ramming hammers cannot ensure ideal ramming effects in various sizes of pole pits. At the same time, the impact height of traditional ramming hammers is usually not adjustable. The impact height is directly related to the ramming force. Different types of soil (such as sandy soil, loam, clay, etc.) and different ramming stages have different requirements for the ramming force. However, traditional equipment cannot achieve dynamic adjustment, making it difficult to accurately control the ramming quality when facing various soil conditions and complex ramming processes. To solve the above problems, the inventor proposes a pole pit ramming device for electric power engineering. SUMMARY

[0020] By adopting the above technical solution, the opening and closing motor 211 drives the opening and closing gear 2111 to rotate, which in turn drives the meshing guide gear 213 to rotate, so that the segmented assembly 212, which cooperates with the guide gear 213 through the guide groove and the opening and closing rod, slides on the cylindrical surface of the compacted base 22 to achieve diameter adjustment.

[0021] The guide gear 213 has guide grooves in the same number as the splitting assembly 212. The splitting assembly 212 is fixedly installed on the lower side of one end of the compacted base 22 with an opening and closing rod. The opening and closing rod passes through the guide groove and is slidably connected to the guide groove.

[0022] By adopting the above technical solution, the guide groove provides a sliding trajectory for the opening and closing rod, ensuring that the split assembly 212 opens and closes accurately, and making the diameter change of the tamping hammer 21 stable and reliable.

[0023] The lower surface of the top end of the tripod 1 is fixedly provided with an impact cylinder 25, the lifting rod 2 penetrates the impact cylinder 25, the part of the lifting rod 2 above the upper surface of the tripod 1 is provided with a steering gear 24, the upper surface of the tripod 1 is fixedly provided with a steering motor 23, and the output end of the steering motor 23 is engaged with the steering gear 24.

[0032] Working Principle: When using this utility model, the operator first pushes the device to the vicinity of the pit to be compacted, rotates the hand crank 114 to raise the threaded rod 111, driving the universal wheel 112 upward, allowing the fixing pin 113 to be inserted into the ground downward, firmly fixing the device. Then, according to the size of the pit and the soil conditions, the operating parameters of the opening and closing motor 211 are set on the remote control device, such as the unfolding diameter of the segmented component 212 and the lifting height of the lifting rod 2. The opening and closing motor 211 drives the opening and closing gear 2111 to rotate, which in turn drives the guide gear 213 to rotate. Through the cooperation of the guide groove 2131 and the opening and closing rod 2121, the segmented component 212 is opened and closed to a suitable size, adjusting the vertical movement of the compaction hammer 21. The system simultaneously sets the operating parameters of the impact cylinder 25, controls the piston rod of the impact cylinder 25 to lift the lifting rod 2 to a specified height, and then releases the piston rod instantly, allowing the lifting rod 2 and the tamping hammer 21 to fall freely for tamping operations. During the tamping process, the steering motor 23 drives the tamping hammer 21 to rotate, which aims to reduce the gaps left by the segmented component 212 during tamping, making the tamping effect more uniform. After one tamping operation is completed, the impact cylinder 25 lifts the lifting rod 2 and the tamping hammer 21 again, and then performs the next tamping operation. This cycle is repeated until the pole pit reaches the specified tamping standard. Throughout the process, all components work together under the unified control of the remote control device to achieve efficient and precise pole pit tamping operations.
