[0008] Preferably, two sets of first sliding grooves arranged in parallel are respectively formed in the front and rear side walls of the machine body, and the left and right ends of the sliding shell are located inside the first sliding grooves and are slidably connected thereto.

[0009] Preferably, the driving part comprises a high-speed oil cylinder fixedly mounted on the upper part of the machine body, one side of the high-speed oil cylinder is provided with an accumulator fixedly mounted inside the machine body, and a valve group for use with the accumulator is fixedly mounted on a side wall of one side of the machine body.

[0011] Preferably, the wrapping shell is composed of two centrally symmetrical monomers, which are tightly fitted together, and a first fixing hole is provided at the upper end of the two monomers. Two symmetrically arranged second fixing holes are provided at the upper end of the fixing shell, and the second fixing holes are located directly below the corresponding first fixing holes.

[0012] Preferably, the fixing shell is made of degradable bioplastic.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. In the present application, by setting up ultrasonic transducers, ultrasonic generators, and amplitude transformers, etc., high-frequency vibration can be used to generate tiny impacts and frictions when the drilling tool contacts the soil, which helps to break the structure of the soil, reduce cutting resistance, and make the soil easier to crush and remove. At the same time, vibration can prompt the soil debris generated by cutting to be quickly discharged from the borehole, reducing the accumulation and blockage of debris, thereby ensuring the continuity and stability of the borehole, and preventing continuous collapse of the soil layer and excessive damage to the soil layer structure. At the same time, the accuracy and straightness of the borehole are improved, making the drilled hole more regular. Because the soil in the gully is relatively loose when it is not compacted, the fixed shell can be better rotated into the soil.

[0018] 2. In the present application, by setting the threaded drill rod, the wrapping shell and the fixed shell, etc., a segmented hole that is wide at the top and narrow at the bottom can be formed inside the soil. The segmented hole can better control the compaction depth, avoiding the problem of under-compacting or over-compacting caused by the compaction being too deep or too shallow. The fixed shell and the threaded shell remaining inside the soil will maintain the stability of the upper soil, so that the soil inside will not fall off.

[0019] 3. In this application, through the arrangement of the high-speed cylinder, accumulator and valve group, the accumulator can be used to store the excess energy generated during the downward impact of the high-speed cylinder so as to release it when needed. At the same time, through its cooperation with the valve group, the energy utilization efficiency can be effectively improved.

[0020] 4. In the present application, by setting the material of the fixed shell to be degradable bioplastic, the fixed shell can be better integrated into the soil. At the same time, by filling the inside of the threaded shell with sodium silicate solution, when the threaded shell is broken as the fixed shell is flattened, the sodium silicate solution inside it will flow into the soil, thereby increasing the adhesion between the particles of the soil and increasing the stability of its compaction.

[0021] In summary, in the present application, the compaction process of the compactor in the prior art is improved through the design of the above-mentioned structure, thereby effectively improving the compaction effect of the soil and improving the uniformity of the soil.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all the embodiments.

[0032] Reference Figures 1 to 8 A compacting machine for electric power construction includes a machine body 1. A connecting frame 5 is fixedly installed on the upper end surface and the lower left surface of the machine body 1. The connecting frame 5 is used to connect the machine body 1 to an external compacting device (such as a compacting vehicle, etc.). A sensor 4 is fixedly installed on the front surface of the machine body 1. The sensor 4 is used to detect the position and movement state of the compacting machine parts to maintain the stability of the device. The specific model can be an Omron E2E proximity sensor 4.

[0033] Two sets of second slide grooves 11 are arranged in parallel on the inner walls on the left and right sides of the body 1, and a sliding plate 13 is slidably connected inside the multiple sets of second slide grooves 11. Two sets of first slide grooves 10 are arranged in parallel on the front and rear side walls of the body 1, and a sliding shell 12 is slidably connected between the two sets of first slide grooves 10. There are two sets of sliding shells 12 in total, and they are respectively located on the front and rear sides of the sliding plate 13. The two sets of sliding shells 12 are fixedly connected to the sliding plate 13.

[0034] A plurality of groups of horn rods 14 are evenly arranged and fixedly installed inside the sliding plate 13. An ultrasonic transducer 15 is fixedly installed on the upper end of the horn rod 14. The ultrasonic transducer 15 is a prior art and is used to convert electromagnetic energy into mechanical energy. A conductive wire 17 is fixedly connected to the upper end surface of the ultrasonic transducer 15. The upper end of the conductive wire 17 is connected to an ultrasonic generator (not shown in the figure). The ultrasonic generator is also a prior art and is used to convert electrical energy into a high-frequency alternating current signal that matches the ultrasonic transducer. A rotating member 16 is movably installed at the lower end of the horn rod 14. A threaded drill rod 18 is threadedly connected to the lower end of the rotating member 16.

[0035] The outer side of the threaded drill rod 18 is covered with a wrapping shell 19, and a spiral protrusion is arranged inside the wrapping shell 19, which is engaged with the thread groove on the outer surface of the threaded drill rod 18, so that when the threaded drill rod 18 rotates, the wrapping shell 19 can be driven to rotate. The wrapping shell 19 is set as two monomers with central symmetry, and the two monomers are tightly fitted, and the upper ends of the two monomers are provided with a first fixing hole 20. A fixed shell 21 is arranged below the wrapping shell 19, and the upper end of the fixed shell 21 is provided with two symmetrically arranged second fixing holes, and the second fixing holes are located directly below the corresponding first fixing holes 20. When the device is used, the two monomers of the wrapping shell 19 can be fixedly connected together through the mutual cooperation of the first fixing hole 20, the second fixing hole and the bolt, and the wrapping shell 19 can also be fixedly connected with the fixed shell 21. The outer surface of the fixed shell 21 is fixedly connected with a threaded shell 22, and the inside of the threaded shell 22 is hollow and filled with sodium silicate solution, and the material of the fixed shell 21 is degradable bioplastic.

[0036] The bottom end of the fixing shell 21 is provided with an opening, and the lower end of the threaded drill rod 18 passes through the opening and is provided with a pointed end, so as to facilitate better insertion of the threaded drill rod 18 into the soil.

[0037] A high-speed oil cylinder 7 is fixedly installed on the upper part of the body 1, the output end of the high-speed oil cylinder 7 faces downward and is fixedly connected to a fixed plate 8 after sliding through the sliding plate 13, the upper end of the fixed plate 8 is fixedly connected to the lower end of the sliding shell 12, a groove is opened in the middle position of the fixed plate 8, a hammer pad 6 is glued inside the groove, and a plurality of through holes are opened on the hammer pad 6 and the bottom wall of the groove, and the through holes correspond to the positions of the threaded drill rod 18 one by one (as shown in the attached manual Figure 2 As shown), it is convenient for the threaded drill rod 18 to pass through the through hole.

[0038] A tamping seat 9 is fixedly connected to the bottom of the fixed plate 8 by bolts. The tamping seat 9 is not installed and used at the same time as the fixed shell 21 and the threaded shell 22. A plurality of inverted triangle-shaped protrusions are fixedly installed on the bottom of the tamping seat 9. The inverted triangle-shaped protrusions at the bottom of the tamping seat 9 can increase the contact area with the soil and better compact the soil.

[0039] An accumulator 2 is fixedly installed on one side of the upper part of the body 1. The accumulator 2 is a prior art. The accumulator 2 is used to store excess energy generated during the downward impact of the high-speed cylinder 7 so as to release it when needed. At the same time, a valve group 3 is fixedly installed on the side wall of one side of the body 1. The valve group 3 is also a prior art and is used in conjunction with the accumulator 2 to improve energy utilization efficiency.

[0040] The specific working principle of the present invention is as follows: first, the connecting frame 5 is fixed on a specially designed compacting vehicle. The design of the connecting frame 5 allows the device to be stably installed on the compacting vehicle. Then, the device is moved to the position where compaction is required by the compacting vehicle, the position of the cable is calculated first, and then the device is slowly lowered. Then, the ultrasonic generator is started to generate a high-frequency electrical signal, usually with a frequency between 20kHz and hundreds of kHz. Then, the electrical signal is converted into mechanical vibration energy through the ultrasonic transducer 15. At this time, the mechanical vibration is transmitted to the amplitude transformer 14, so that the force it conducts is changed, thereby driving the rotating member 16 to rotate and vibrate, and the rotation and vibration of the rotating member 16 will drive the efficiency to the threaded drill rod 18, causing it to rotate and vibrate.

[0041] At this time, the device slowly descends, and the use of ultrasonic assisted drilling can produce tiny impacts and frictions at the moment of contact between the drilling tool and the soil through high-frequency vibration. This helps to break the structure of the soil, reduce cutting resistance, and make the soil easier to break and remove. At the same time, vibration can prompt the soil debris produced by cutting to be quickly discharged from the borehole, reducing the accumulation and blockage of debris, thereby ensuring the continuity and stability of the borehole, and preventing continuous collapse of the soil layer and excessive damage to the soil layer structure. At the same time, the accuracy and straightness of the drilling are improved, making the drilled hole more regular. Because the soil in the gully is relatively loose when it is not compacted, the fixed shell 21 can be better rotated into the soil. When the fixed shell 21 is completely in the soil, the machine is stopped and it is stationary.

[0042] After that, the thread connected to the first fixing hole 20 is twisted off to disengage the outer side of the wrapping shell 19 and the outer side surface of the fixed shell 21. Then, the staff separates the two sides of the wrapping shell 19 and takes it out from the gap at the upper end of the fixed shell 21. At this time, the fixed shell 21 has no direct connection with the threaded drill rod 18 and will no longer rotate, so that the fixed shell 21 remains inside the soil. Then, the device is started again to allow the threaded drill rod 18 to continue to extend downward and stop at a suitable position to prevent damage to the cable. At this time, a segmented hole with a wide top and a narrow bottom is formed inside the soil. The segmented hole can better control the compaction depth and avoid the problems of under-compacting and over-compacting due to over-deep or over-shallow compaction. The fixed shell 21 and the threaded shell 22 remaining in the soil will maintain the stability of the upper soil to prevent the soil inside from falling off.

[0043] Thereafter, the machine body 1 is lifted upward, and the threaded drill rod 18 is disassembled to disengage it from the rotating part 16. Then, the tamping seat 9 and the fixed plate 8 are bolted together to fix them. The inverted triangular protrusion at the bottom of the tamping seat 9 can increase the contact area with the soil and compact the soil better. Then, the high-speed cylinder 7 is started, and after starting, the fixed plate 8 and the tamping seat 9 at the bottom are driven to be lifted. When lifting, the sliding shell 12 and the sliding plate 13 will be driven to slide in the first slide groove 10 and the second slide groove 11, thereby driving the amplitude change rod 14 to slide so that it will not be damaged. Then, the high-speed cylinder 7 is pressed downward to impact for compaction. There will be a short period of excess energy during the impact, which will be stored in the accumulator 2.

[0044] The accumulator 2 can store this excess energy so that it can be released when needed, thereby improving energy utilization efficiency. When the tamping seat 9 performs impact tamping, due to the design of the cable trench itself, the space in the backfill area is limited. During the impact, the soil will be squeezed outward and compacted. Due to the limitations of the gully walls on the upper and lower sides, the soil will be squeezed to make the soil better compacted. When the impact force squeezes the soil, the fixed shell 21 buried in the soil will be flattened. At this time, the underground fixed shell 21 will be crushed and flattened. After multiple impact tamping, the material design of the fixed shell 21 allows it to be better integrated into the soil, and the threaded shell 22 will also break as the fixed shell 21 is flattened, allowing the sodium silicate solution inside it to flow into the soil, increasing the adhesion between the particles in the soil and increasing the stability of its compaction. The sensor 4 on the tamping machine can be used to detect the position and movement state of the tamping machine components to maintain the stability of the device.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
