[0002] When building power grid towers on hillsides and fields, the fixed pile foundations under the towers need to be drilled and then expanded by a pile foundation well boring machine. The deep foundation consisting of piles and pile caps connected to the top of the piles is referred to as caps, or the single pile foundation connected by columns and pile foundations is referred to as pile foundations. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation.

[0003] When installing existing power grid towers, they need to be erected on soil surfaces with high slopes such as mountainous areas. However, the existing erection equipment cannot effectively adapt to slopes of various inclinations during erection, and is prone to tilting during drilling, affecting the normal processing progress of the pile foundation well.

When in use, the mounting seat is laid on the ground, at this time, the top block and the adjustment plate are not in contact, and the angle of the rotating plate changes under the ups and downs of the ground and is attached to the slope of the ground. Then, by rotating the connecting rod, it moves in the threaded groove, driving the top block to rotate, and driving the arc surface to rotate. As the top block rotates, one end of the protrusion gradually abuts against the surface of the adjusting plate, exerting a lateral thrust on the rotating plate, driving the rotating plate to abut against the soil surface. Then, by rotating the locking nut to abut against the top of the mounting seat, the connecting rod is effectively positioned to prevent it from driving the top block to rotate under external pressure. The placement angle can be automatically adjusted according to the ground, and then the locking position can be quickly performed. The entire erection mechanism can be effectively attached to the ground and has a good locking effect, converting the upward thrust into a lateral force.

[0025] See also Figure 1-5 The present invention provides a technical solution: an automatic drilling machine for pile foundation wells that can be easily erected, comprising a mounting seat 1 and a frame 2 fixed above the mounting seat 1, a drilling mechanism 3 is arranged on the side of the frame 2, and the side of the mounting seat 1 is installed on the ground through an erection mechanism;

[0026] The mounting mechanism includes a rotating plate 4 and a plug-in rod 7 which are rotatably arranged on the side of the mounting seat 1 through a rotating groove 6. The inner cavity of the mounting seat 1 is respectively provided with a thread groove 12, an embedded groove 10 and an inserting groove 21 from top to bottom. The surface of the inserting rod 7 is provided with a thread 8 threadedly connected to the thread groove 12. The end of the inserting rod 7 is plugged into the inserting groove 21. The surface of the inserting rod 7 between the thread groove 12 and the inserting groove 21 is fixedly connected with a top block 11 rotatably arranged in the embedded groove 10. The surface of the top block 11 is provided with an arc surface 13. The top of the rotating plate 4 is fixedly connected with an adjusting plate 5 abutting against the surface of the arc surface 13. When in use, the mounting seat 1 is laid on the ground. At this time, the top block 11 and the adjusting plate 5 are not in contact. Under the ups and downs of the ground, the angle of the rotating plate 4 changes and is attached to the slope of the ground. Then, by rotating the inserting rod 7, it moves in the thread groove 12, driving the top block 11 to rotate, and driving the arc surface 13 to rotate. The locking nut 9 is then rotated to abut against the top of the mounting base 1, and the plug-in rod 7 is effectively positioned to prevent it from driving the top block 11 to rotate under external pressure. The placement angle can be automatically adjusted according to the ground, and then the locking positioning can be quickly performed. The entire erection mechanism can be effectively attached to the ground, and the locking effect is good, and the upward thrust is converted into a lateral force, which is not easy to loosen and is easy to erect. It can be laid even on a slope with a high slope, which solves the problem that the existing power grid tower needs to be erected on a soil surface with a high slope such as in mountainous areas during installation, but the existing erection equipment cannot effectively adapt to slopes of various inclinations during erection, and is prone to tilting during drilling, affecting the normal processing progress of the pile foundation well.

[0027] The threaded groove 12 is located on the surface above the mounting seat 1 and is threadedly connected to a locking nut 9. The bottom of the locking nut 9 abuts against the top of the mounting seat 1. By rotating the locking nut 9 to abut against the top of the mounting seat 1, the plug-in rod 7 is effectively positioned to prevent it from driving the top block 11 to rotate under external pressure.

[0028] There are four erection mechanisms, which are symmetrically distributed around the mounting base 1 and are set at four angles. The angle-adjustable support setting of the erection mechanism can be used for erection support on different ground surfaces.

[0029] The bottom of the rotating plate 4 is fixedly connected with a grounding pad 20, and a plurality of rivets are arranged at the bottom of the grounding pad 20. Through the plurality of rivet protrusions, the grounding pad 20 can be more closely contacted with the ground when pressed down, and has stronger stability.

[0030] An auxiliary mounting mechanism is provided on the surface of the frame 2, and the auxiliary mounting mechanism includes a force-bearing frame 14 and a ground nail 17 which are sleeved on the surface of the frame 2. A vibration motor 15 is installed on the top of the force-bearing frame 14 through a mounting groove 16. The vibration end of the vibration motor 15 abuts against the surface of the force-bearing frame 14. The top of the ground nail 17 is fixedly connected with a conduction plate 18 abutting against the bottom of the force-bearing frame 14. The vibration of the vibration motor 15 above the force-bearing frame 14 drives the ground nail 17 to vibrate through the conduction plate 18. The ground nail 17 is inserted into a small hole opened in advance, and the vibration of the vibration motor 15 is continuous. When the ground nail 17 is inserted, the soil inside is compacted, and multiple ground nails 17 can be quickly fixed at the same time to ensure the overall stability of the device.

[0031] The inner cavity of the rotating plate 4 is provided with a through groove 19 for the ground nail 17 to pass through. The top of the ground nail 17 is fixedly connected to a limiting frame 22. After passing through the through groove 19, the ground nail 17 is inserted into the ground to increase the grip, and is abutted against the surface of the rotating plate 4 through the limiting frame 22 to prevent the ground nail 17 from falling off from the through groove 19.

[0032] The force-bearing frame 14 is a rectangular frame and can be conveniently mounted on the surface of the frame 2 .

[0033] The arc surface 13 is provided with anti-skid patterns, which can effectively prevent it from slipping when it contacts the surface of the adjustment plate 5 .
