Description

Technical Field

[0001] The present invention relates to the technical field related to drilling construction equipment, and in particular to a PHC pipe pile construction device for a photovoltaic component support. Background Art

[0002] Against the backdrop of accelerating global energy transition, photovoltaic power generation, as an important component of clean energy, has seen continued rapid growth in installed capacity. The foundation of photovoltaic module supports is key to ensuring the stable operation of photovoltaic power stations. PHC (prestressed high-strength concrete) pipe piles have become a common choice for the construction of photovoltaic module support foundations due to their high strength, convenient construction, and good durability. During the construction of PHC pipe piles, it is necessary to overcome the challenges of complex geological conditions and achieve precise construction.

[0003] Currently, in the construction of photovoltaic power stations, PHC pipe pile construction faces many problems. Under complex geological conditions, such as rock layers, hard soil layers and other areas, traditional PHC pipe pile construction equipment is difficult to efficiently penetrate the strata and accurately implant the pipe piles into the predetermined positions. Existing devices mostly use hammering or static pressure to sink piles. When encountering hard geology, the hammering method can easily cause damage to the pipe piles, and the construction noise and vibration are high, which will have an adverse impact on the surrounding environment. Although the static pressure method is quieter, it is limited by the tonnage of the equipment and it is difficult to reach the designed depth in the hard strata, resulting in insufficient bearing capacity of the pipe piles, affecting the stability of the photovoltaic module support.

[0004] Chinese patent publication number CN118462051A discloses a PHC pipe pile inner drilling device and a construction method thereof, wherein the drilling device includes a hydraulic jack, a drill rod, a drill bit, a transition sleeve and a guide device, wherein the two ends of the drill rod are fixed with a hydraulic jack and a drill bit respectively, and the transition sleeve is sleeved on the drill rod; the guide device includes a connecting rod, a contact wheel, a rotary gripper and a shock absorber, wherein one end of the connecting rod is hinged to the outer wall of the transition sleeve, and the other end is connected to one end of the rotary gripper through a bearing, and the contact wheel is installed on the rotary gripper. The other end of the device; one end of the shock absorber is connected to the rod body of the connecting rod through a connecting casing, and the other end is hinged to the transition sleeve. This device can solve the technical problem of drilling in the rock-embedded section of the PHC pile + cast-in-place rock-embedded pile combination, ensure the inclination of the drill rod, reduce the risk of damage to the quality of the concrete on the inner wall of the PHC pipe pile during the drilling process, reduce the risk of drill sticking, and improve the quality and efficiency of drilling construction. However, in actual use, this device cannot realize the integrated linkage control and automated operation of installation and drilling, which increases the installation and drilling time of a single pipe string and reduces the overall construction efficiency.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1, as Figure 1 and Figure 2 As shown, this embodiment discloses a PHC pipe pile construction device for a photovoltaic component bracket, including a circular mounting groove 1, a limiting device 2 is provided in the middle of the inner cavity of the circular mounting groove 1, a lifting device 3 is provided on one side of the upper end of the limiting device 2, and a braking device 4 is provided in the middle of the inner cavity of the lifting device 3.

[0033] Specifically, before installing the PHC pipe pile, a hole of a certain depth needs to be drilled on the ground. Therefore, this construction device is needed to drill holes on the ground. This construction device needs to be installed on a corresponding mobile device. When it is necessary to drill holes in the ground, the staff transports the construction device to the corresponding construction position through the relevant mobile device, and then the staff adjusts the position of the brake device 4 through the limit device 2 and the lifting device 3, so that the brake device 4 can move to a position suitable for drilling. After that, the staff controls the operation of the brake device 4, and at the same time, the lifting device 3 drives the brake device 4 to move downward, so that the brake device 4 performs drilling operations on the ground.

[0034] During the drilling process, if the construction device is fixed but the drilling position does not meet the conditions, the lifting device 3 and the braking device 4 can be adjusted through the limit device 2, such as Figure 3 and Figure 4As shown, the limiting device 2 includes a fixed plate 21, which is rotatably installed in the middle of the inner cavity of the circular mounting groove 1. An arc-shaped support rod 22 is provided on one side of the outer surface of the fixed plate 21. Arc-shaped racks are provided on the outer surfaces of the fixed plate 21 and the arc-shaped support rod 22. A gear 23 rotatably installed in the inner cavity of the circular mounting groove 1 is provided on the side of the outer surface of the arc-shaped support rod 22 away from the lifting device 3. The gear 23 is meshed with the arc-shaped racks on the outer surfaces of the fixed plate 21 and the arc-shaped support rod 22. A handwheel 24 is provided on the upper end of the gear 23, and a dustproof plate 25 is rotatably installed on the upper end of the circular mounting groove 1.

[0035] Specifically, after the relevant mobile device transports the construction device to the corresponding position and fixes it, if it is necessary to fine-tune the position of the construction device, the process of adjusting the position of the construction device through the mobile device is relatively cumbersome. At this time, the staff can turn the handwheel 24, and the handwheel 24 drives the fixed plate 21 and the arc-shaped support rod 22 to rotate through the gear 23 and the arc-shaped rack on the outer surface of the fixed plate 21 and the arc-shaped support rod 22, thereby causing the fixed plate 21 to drive the lifting device 3 and the braking device 4 to move, thereby adjusting the position of the braking device 4 and moving the braking device 4 to above the corresponding punching position.

[0036] In order to install the brake device 4, at the same time, the brake device 4 is controlled to move up and down, such as Figure 5 and Figure 6 As shown, the lifting device 3 includes a support frame 31, and limiting holes 311 are provided on both sides of the outer surface of the support frame 31. A mounting plate 33 is provided at the lower end of the support frame 31, and the lower end of the mounting plate 33 is fixedly connected to the upper end of the fixing plate 21. The outer surface of the mounting plate 33 is fixedly connected to the outer surface of the dustproof plate 25. Hydraulic cylinders 32 are provided on both sides of the inner cavity of the support frame 31, and double-headed hydraulic cylinders 34 are provided on both sides of the upper end of the mounting plate 33. The upper parts of the two double-headed hydraulic cylinders 34 are rotatably connected to the two sides of the upper part of the outer surface of the support frame 31 respectively. Two supporting telescopic rods 35 are provided on the side of the lower part of the outer surface of the support frame 31 away from the double-headed hydraulic cylinder 34. Fenders 36 are provided on the outer surface of the support frame 31 near both sides, and the lower parts of the outer surfaces of the two fenders 36 are fixedly connected to the outer surface of the dustproof plate 25.

[0037] Specifically, after the staff transports the construction device to the corresponding position through the mobile device, the two double-headed hydraulic cylinders 34 extend to lift the support frame 31 and push the support frame 31 to an angle, which is adjusted according to the angle of the hole punched by the brake device 4. When the two double-headed hydraulic cylinders 34 push the support frame 31 to the corresponding angle, the staff adjusts the position of the lifting device 3 and the brake device 4 through the limit device 2.

[0038] Furthermore, after the staff has adjusted the position and angle of the lifting device 3, the staff controls the operation of the braking device 4. At the same time, the staff controls the operation of the two hydraulic cylinders 1 32, so that the two hydraulic cylinders 1 32 drive the braking device 4 to move downward, thereby causing the braking device 4 to drill holes in the ground.

[0039] Furthermore, after the two double-headed hydraulic cylinders 34 push the support frame 31 to the corresponding angle, the two supporting telescopic rods 35 need to be extended to support the supporting telescopic rods 35. During the drilling process of the braking device 4, the mudguards 36 on both sides can provide protection to prevent mud from splashing to the upper end of the limiting device 2 to a great extent.

[0040] During the installation of the PHC pile, it is necessary to first drill a hole in the ground through the braking device 4, and then put the PHC pile in. Figure 7 and Figure 8 As shown, the braking device 4 includes a transmission member 41, and support blocks 44 are provided on both sides of the outer surface of the transmission member 41. The two support blocks 44 are slidably installed on the inner cavity surface of the support frame 31, and the inner surfaces of the two support blocks 44 are fixedly connected to the outer surfaces of the two hydraulic cylinders 32 respectively. A push plate 45 is provided on the side of the outer surfaces of the two support blocks 44 away from each other. The two push plates 45 extend to the outside of the support frame 31, and the outer surfaces of the two push plates 45 are slidably connected to the inner surfaces of the two limiting holes 311 respectively. A spiral drill bit 43 is provided in the middle of the transmission member 41, and the lower part of the spiral drill bit 43 extends to the outside of the support frame 31. The upper end of the transmission member 41 is provided with a motor 42 for transmitting kinetic energy to the spiral drill bit 43.

[0041] Specifically, when the two double-headed hydraulic cylinders 34 push the support frame 31 to the corresponding angle, the transmission member 41 is slidably installed in the inner cavity of the support frame 31 under the action of the two support blocks 44, and the transmission member 41 also moves with the support frame 31 to an angle suitable for the opening.

[0042] Furthermore, when the lifting device 3 is fixed, the motor 42 drives the spiral drill bit 43 to rotate through the transmission member 41. At this time, the two hydraulic cylinders 32 drive the transmission member 41 to move downward through the two support blocks 44, and then the transmission member 41 drives the spiral drill bit 43 to move downward to perform drilling operations on the ground.

[0043] Embodiment 2: This embodiment further improves the placing device 7 based on the embodiment 1. Figure 1 and Figure 2 As shown, driven devices 5 are provided on both sides of the upper outer surface of the lifting device 3, a holding frame 6 is provided on the other side of the upper end of the limiting device 2, a plurality of PHC pile bodies 8 are provided in the middle of the inner cavity of the holding frame 6, and a releasing device 7 is provided on the lower side of the lifting device 3 close to the holding frame 6.

[0044] Specifically, before the braking device 4 performs the drilling operation, the staff can place multiple PHC pile bodies 8 in the inner cavity of the containing frame 6 so that the PHC pile bodies 8 can be installed later. At the same time, a PHC pile body 8 is placed on the upper part of the releasing device 7, and the releasing device 7 will clamp the PHC pile body 8. When the braking device 4 digs a hole, the lifting device 3 drives the braking device 4 to move upward. After the braking device 4 moves upward to the corresponding height, the braking device 4 will drive the two driven devices 5 to operate, and then the driven device 5 drives the releasing device 7 to operate.

[0045] Furthermore, when the placing device 7 is in operation, the placing device 7 can place the PHC pile body 8 placed on the upper portion thereof into the dug hole, eliminating the need for workers to place the pile separately, thereby increasing work efficiency.

[0046] In order to utilize the lifting device 3 to drive the braking device 4 upward to drive the release device 7 to operate, as shown in FIG. Figure 9 As shown, the driven device 5 includes a hydraulic frame 51, which is fixedly mounted on the outer surface of the support frame 31. A piston 52 is provided at the lower part of the inner cavity of the hydraulic frame 51. The upper end of the piston 52 is provided with a spring fixedly mounted on the top wall of the inner cavity of the hydraulic frame 51. A push rod 53 is provided at the lower end of the piston 52. The lower end of the push rod 53 extends to the outside of the hydraulic frame 51. The push rod 53 is adapted for use with the push plate 45 on the same side.

[0047] Specifically, in the process of the two hydraulic cylinders 32 driving the transmission member 41 to move upward through the two support blocks 44, the two support blocks 44 will also drive the two push plates 45 to move upward during the upward movement. When the two push plates 45 move upward to the corresponding heights respectively along with the two support blocks 44, the upper ends of the two push plates 45 will respectively contact the push rods 53 in the two driven devices 5, and then the two push plates 45 will respectively drive the two pistons 52 to move upward through the two push rods 53. When the two pistons 52 move upward, they will squeeze the hydraulic oil in the inner cavity of the hydraulic frame 51, thereby causing the hydraulic oil in the inner cavity of the hydraulic frame 51 to flow into the inner cavity of the applying device 7.

[0048] When the brake device 4 has finished drilling the hole on the ground, the driven device 5 uses the lifting device 3 to drive the brake device 4 upward to drive the placing device 7 to operate, so that the placing device 7 puts the PHC pile body 8 placed on it into the hole drilled by the brake device 4. Figure 9 As shown, the releasing device 7 includes a support handle 71, which is fixedly mounted on the upper end of the mounting plate 33 near the side of the support frame 31. The upper end of the support handle 71 is provided with a pushing mechanism 72, and the upper end of the pushing mechanism 72 is provided with a clamping mechanism 73.

[0049] Specifically, when the braking device 4 completes the drilling operation, the lifting device 3 drives the braking device 4 to move upward, and then the braking device 4 drives the two driven devices 5 to operate. The hydraulic oil in the inner cavity of the two driven devices 5 will flow into the inner cavity of the pushing mechanism 72, so that the pushing mechanism 72 drives the clamping mechanism 73 to rotate upward to make the clamping mechanism 73 erect. Then the clamping mechanism 73 releases the PHC pile body 8 and places the PHC pile body 8 into the hole drilled by the braking device 4.

[0050] In order to achieve the purpose of placing the PHC pile body 8 placed on the upper part of the placing device 7 into the drilled hole, as shown in FIG. Figure 10 As shown, the pushing mechanism 72 includes a support plate 721, which is rotatably mounted on the upper end of the support handle 71. A hydraulic rod 722 is provided in the middle of the inner cavity of the support plate 721, and the outer surface of the hydraulic rod 722 is rotatably mounted on the upper end of the support handle 71 near the side of the support frame 31.

[0051] Further, such as Figure 9 As shown, the inner cavity of the hydraulic rod 722 is communicated with the inner cavities of the hydraulic frames 51 in the two driven devices 5 through two hydraulic pipes respectively.

[0052] Further, such as Figure 11 As shown, the clamping mechanism 73 includes a support frame 731, which is fixedly mounted on the upper end of the support plate 721. Mounting plates 732 are provided on both sides of the outer surface of the support frame 731. Clamping claws 733 are rotatably mounted on both sides of the outer surfaces of the two mounting plates 732. A small hydraulic cylinder 734 is provided on the lower part of the outer surface of the two clamping claws 733 mounted on the outer surface of the same mounting plate 732.

[0053] Specifically, before the braking device 4 is drilled, the staff needs to place a PHC pipe pile body 8 in the inner cavity of the containing frame 6 into the upper part of the support frame 731, and then the staff controls the output of the two small hydraulic cylinders 734 to make the two clamps 733 connected to the same small hydraulic cylinder 734 rotate on the outer surface of the mounting plate 732, so that the two clamps 733 move toward each other, and then the two clamps 733 clamp the PHC pipe pile body 8 placed on the upper part of the support frame 731.

[0054] Furthermore, when the hydraulic oil in the inner cavity of the hydraulic frame 51 is squeezed out by the action of the piston 52, the hydraulic oil is introduced into the inner cavity of the hydraulic rod 722 through the hydraulic pipe, so that the hydraulic rod 722 pushes the support plate 721 to rotate upward, and then the hydraulic rod 722 drives the PHC pile body 8 to rotate upward through the clamping mechanism 73, so that the PHC pile body 8 is vertical. Then the staff controls the two small hydraulic cylinders 734 to contract, so that the four clamping claws 733 release the fixed state of the PHC pile body 8. At this time, the PHC pile body 8 falls into the hole drilled by the braking device 4 under the action of gravity, realizing integrated linkage control and automated operation of installation and drilling, shortening the installation and drilling time of a single pipe column, improving the overall construction efficiency, and effectively shortening the project construction period.

[0055] Furthermore, after the placing device 7 places the PHC pile body 8 in the hole drilled by the braking device 4, the corresponding moving device lifts the construction device upward, and then the corresponding moving device transports the construction device to the next construction position.

[0056] It should be noted that the specific installation method, circuit arrangement connection method and control method of the hydraulic cylinder 1 32, double-head hydraulic cylinder 34 and motor 42 used in the above-mentioned embodiment 1 and the small hydraulic cylinder 2 734 used in the embodiment 2 are all conventional designs in the prior art and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
