Description

Technical Field

[0001] This invention relates to the field of power distribution network engineering equipment technology, and in particular to a multi-purpose engineering operation vehicle for drilling, erecting poles, and stringing lines in power distribution network engineering. Background Technology

[0002] In the construction of power distribution networks, drilling, pole erection, and wire stringing are crucial steps, and their efficiency and quality directly affect the progress and later operational stability of the entire network. In traditional power distribution network construction, these steps often require the coordinated use of various different pieces of equipment, which is not only cumbersome in terms of equipment handling and scheduling, but also consumes a significant amount of manpower, material resources, and time. Traditional drilling and pole erection equipment operate independently. After drilling is complete, the pole erection equipment needs to be repositioned. During this process, the soil around the hole can easily loosen and fall into the hole, requiring the hole to be cleaned before subsequent pole erection. This wastes time and affects the accuracy of the pole erection. Moreover, even after cleaning, it is difficult to quickly and accurately align the utility pole with the hole during the erection process, often requiring multiple adjustments, which greatly reduces work efficiency. Traditional pole erection methods rely heavily on manual labor combined with simple machinery, which is not only labor-intensive but also poses significant safety hazards. Especially during the lifting and erection of utility poles, it is difficult to guarantee their stability and verticality, leading to tilting or even collapse, threatening the safety of construction workers. Furthermore, because drilling and pole erection equipment are independent, each power grid project requires drilling holes first, then removing the drilling equipment before erecting the poles. Alignment between the pole and the hole is also necessary during erection, significantly reducing overall efficiency.

[0003] Therefore, it is necessary to design a multi-purpose engineering vehicle for drilling, erecting poles, and stringing lines in power distribution network projects to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-purpose engineering vehicle for drilling, erecting poles, and stringing lines in power distribution network projects. This invention combines drilling and pole erection, allowing for quick alignment and insertion of the pole into the hole after each drilling operation. Furthermore, the push component pushes the soil around the hole away from it during drilling, preventing soil from falling into the hole during subsequent pole placement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-purpose engineering vehicle for drilling, erecting poles, and stringing power distribution lines includes a vehicle body with a robotic arm mounted on it.

Two first hydraulic rods 5 are provided at the lower end of the switching disk 4. The first hydraulic rods 5 are multi-stage telescopic hydraulic rods, which can provide a large thrust and telescopic stroke. A drilling assembly and a clamping rod assembly are installed at the lower end of the switching disk 4.

The upper end of the first hydraulic rod 5 located on the front side passes through the switching disc 4. Both the output shafts of the first hydraulic rod 5 and the second motor 6 are equipped with meshing bevel gears 7. Through the transmission of the bevel gears 7, the power of the second motor 6 can be transmitted to the first hydraulic rod 5. The rotating rod 8 is fixedly connected to the telescopic end of the first hydraulic rod 5 located on the front side. The clamping rod assembly includes a connecting seat 32, and the lower end of the connecting seat 32 is fitted with... It is equipped with two slide rails 34 and two second hydraulic rods 35. The telescopic ends of the two second hydraulic rods 35 are fixedly connected to the fixing blocks 33. The two fixing blocks 33 are slidably connected to the two slide rails 34. The lower ends of the two fixing blocks 33 are fixedly connected to the grippers 30. The opposite sides of the two grippers 30 are fixedly connected to the anti-slip pads. The anti-slip pads are made of rubber and have diamond-shaped anti-slip patterns on their surface, which can increase the friction between the anti-slip pads and the utility poles and prevent slippage during clamping. The inner walls of the two grippers 30 are V-shaped to accommodate the clamping needs of utility poles of different diameters.

[0019] The lower end of the switching disk 4 is equipped with a bulldozing assembly, which is used to push away the soil generated during drilling from around the hole. The bulldozing assembly includes a rectangular box 12 fixedly connected to the lower end of the switching disk 4. A first hydraulic rod 5 located on the front side passes through the rectangular box 12. An incomplete gear 17 is fixedly connected to the first hydraulic rod 5. Two moving blocks 15 are slidably connected inside the rectangular box 12. The two moving blocks 15 are elastically connected to the left and right inner walls of the rectangular box 12 through a first spring 13, which can drive the moving blocks 15 to reset when the incomplete gear 17 is not engaged. A first rack 18 is fixedly connected to the adjacent sides of the two moving blocks 15. Each of the two movable blocks 15 has a through-hole 28, and the two first racks 18 pass through the corresponding through-hole 28. The lower end of the rectangular box 12 has a strip opening 14. The lower ends of the two movable blocks 15 are fixedly connected to vertical rods 16, and the two vertical rods 16 pass through the strip openings 14. The lower ends of the two vertical rods 16 are provided with arc-shaped blocks 10. The curvature of the arc-shaped blocks 10 is adapted to the curvature of the outer wall of the spiral blade 9, so that it can move in close contact with the spiral blade 9.

The lower ends of the two bulldozer plates 11 are both inclined to avoid obstruction when inserting into the soil.

[0020] Each of the two vertical rods 16 has a lifting groove on its front side. An electromagnet 20 is installed on the top of each lifting groove. The electromagnet 20 is a DC electromagnet, and the magnetic force can be controlled by current. A connecting rod 19 is slidably connected in each of the two lifting grooves. The lower end of the two connecting rods 19 is fixedly connected to the corresponding arc block 10. The two electromagnets 20 are elastically connected to the adjacent sides of the corresponding connecting rods 19 by a second spring 21. Pressure sensors 36 are provided on the inner walls of the left and right sides of the rectangular box 12. The connecting rods 19 are made of iron. When the electromagnets 20 are energized, they attract the opposite polarity of the adjacent sides of the connecting rods 19. A controller is provided in the vehicle body 1. The controller is a PLC controller, which can receive and process the signals of each sensor and control the action of the actuator. When the moving block 15 squeezes the pressure sensor 36, an electrical signal is generated and transmitted to the controller. The controller controls the corresponding electromagnet 20 to be energized for a period of time to attract the connecting rod 19.

[0021] The first hydraulic rod 5 located at the rear has a rectangular block 23 fixedly connected to its telescopic end. A rotating shaft 29 is rotatably connected through the rectangular block 23. A rotating block 31 is fixedly connected to the rear side of the rotating shaft 29. A connecting seat 32 is fixedly connected to the rotating block 31. A rotating gear 24 is installed on the rotating shaft 29. A second rack 25 that meshes with the rotating gear 24 is provided at the lower end of the switching disk 4. A damping bearing is provided at the rotating connection between the rotating shaft 29 and the rectangular block 23 to provide appropriate damping force and prevent the utility pole from shaking when rotating and moving. After the clamping rod assembly clamps the middle of the utility pole and moves it upward, the utility pole is rotated to a vertical state by the second rack 25 and the rotating gear 24.

[0022] The lower end of the switching disk 4 is provided with an adjustment groove. A pneumatic rod 27 is fixedly connected to the inner wall of the front side of the adjustment groove. An adjustment block 26 is fixedly connected to the telescopic end of the pneumatic rod 27. The first hydraulic rod 5 and the second rack 25 located on the rear side are both fixedly connected to the lower end of the adjustment block 26. The switching disk 4 is provided with a quarter groove, which facilitates the adjustment of the position of the utility pole in the vertical state.

[0023] The functional principle of this invention can be explained by the following operation: First, prepare for drilling operation. After driving the vehicle body 1 to the designated construction position, adjust the support legs at the lower end of the vehicle body 1 so that the anti-slip bottom plate is in close contact with the ground, thereby enhancing the stability of the vehicle body 1. Then, adjust the position of the switching plate 4 through the robotic arm 2 so that the drilling component is accurately aligned with the area to be drilled. Next, drilling and bulldozing operations are carried out. The second motor 6 is started, and its output shaft drives the first hydraulic rod 5 on the front side to rotate through the bevel gear 7. This, in turn, drives the rotating rod 8 and the spiral blade 9 to rotate. At the same time, the telescopic end of the first hydraulic rod 5 on the front side extends downward, driving the rotating rod 8 to drill downward into the soil to complete the drilling. During the drilling process, the incomplete gear 17 on the first hydraulic rod 5 on the front side rotates with it, alternately meshing with the first rack 18 on the two moving blocks 15. This causes the two moving blocks 15 to slide back and forth in the rectangular box 12. Through the connecting rod 19, the arc-shaped block 10 and the bulldozing plate 11 move synchronously, pushing the soil around the hole away from the hole. When the moving block 15 presses the pressure sensor 36, the controller will control the corresponding electromagnet 20 to be energized for a period of time, which will generate an attraction force on the iron connecting rod 19, causing the connecting rod 19 and the arc block 10 to move upward. This action is to prevent the arc block 10 from contacting the soil excavated during the bulldozing process when the moving block 15 moves the arc block 10 back, thereby preventing the soil from accumulating on the spiral blade 9 and ensuring the bulldozing effect and smooth drilling operation. After a period of time, the electromagnet 20 is de-energized, and under the action of the second spring 21, the arc block 10 moves downward and is inserted between the soil and the spiral blade 9 again. While drilling is being carried out, the clamping operation of the utility pole can be performed simultaneously. The telescopic end of the first hydraulic rod 5 located at the rear extends downward, causing the clamping rod assembly to move downward. During the downward movement, the rotating gear 24 on the rotating shaft 29 meshes with the second rack 25, causing the clamping assembly to rotate accordingly. When the rotating gear 24 and the second rack 25 are not meshed, the jaws 30 face downward. When the two jaws 30 move to the sides of the utility pole, the second hydraulic rod 35 is controlled to move, pushing the fixing block 33 to slide along the slide rail 34, causing the two jaws 30 to move closer to each other and clamp the middle part of the utility pole. Then, the first hydraulic rod 5 at the rear is controlled to retract, lifting the utility pole. After being lifted to a certain height, the rotating gear 24 meshes with the second rack 25 again. As the first hydraulic rod 5 continues to retract, the rotating shaft 29 drives the clamping rod assembly and the utility pole to rotate, thereby rotating the utility pole to a vertical position. After drilling is completed, the process switches to pole erection. The first hydraulic rod 5 on the front retracts, driving the rotating rod 8 out of the hole. Then, the first motor 3 drives the thick rod 22 and the switching disk 4 to rotate, rotating the clamping rod assembly to the original position of the drilling assembly. Subsequently, the pneumatic rod 27 extends and retracts, causing the adjusting block 26 to move and adjust the position of the utility pole, which is already in a vertical position, so that the utility pole and the rotating shaft 29 are on the same rotation trajectory, ensuring the accuracy of subsequent alignment with the hole. Move the vertical utility pole above the hole, and use the positional accuracy adjusted by the pneumatic rod 27 to quickly align and insert the utility pole into the hole, completing the entire pole erection operation.
