Description

Technical Field

[0001] The present invention relates to the technical field of drilling construction equipment, and particularly relates to a construction device for PHC pipe piles of a photovoltaic module support. Background Art

[0002] Under the background of the global acceleration of energy transformation, as an important part of clean energy, the installed capacity of photovoltaic power generation continues to grow rapidly. The foundation of the photovoltaic module support is the key to ensuring the stable operation of the photovoltaic power station. PHC (prestressed high-strength concrete) pipe piles have become a common choice for the construction of the foundation of photovoltaic module supports due to their high strength, convenient construction, good durability, etc. 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, the construction of PHC pipe piles faces many problems. In complex geological conditions, such as rock layers and hard soil layers, traditional PHC pipe pile construction devices are difficult to efficiently penetrate the formation and accurately implant the pipe piles into the predetermined positions. Existing devices mostly use the hammering or static pressure method to sink the piles. When encountering hard geology, the hammering method is likely to cause damage to the pipe piles, and the construction noise is large and the vibration is strong, which will have an adverse impact on the surrounding environment. Although the static pressure method is relatively quiet, due to the limitation of the equipment tonnage, it is difficult to reach the design depth in hard strata, resulting in insufficient bearing capacity of the pipe piles and affecting the stability of the photovoltaic module support.

[0004] Chinese Patent Publication No. CN118462051A discloses a PHC pipe pile internal drilling device and its construction method. The drilling device includes a hydraulic pusher, a drill pipe, a drill bit, a transition sleeve and a guiding device. The two ends of the drill pipe are respectively fixed to the hydraulic pusher and the drill bit, and the transition sleeve is sleeved on the drill pipe; the guiding device includes a connecting rod, a contact wheel, a rotating gripper and a shock absorber. 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 rotating gripper through a bearing. The contact wheel is installed at the other end of the rotating gripper; one end of the shock absorber is connected to the rod body of the connecting rod through a connecting cylinder, and the other end is hinged to the transition sleeve. This device can solve the technical problem of the hole formation of the rock-socketed section of the PHC pile + cast-in-place rock-socketed pile composite pile, ensure the inclination of the drill pipe, reduce the risk of damage to the concrete quality of the inner wall of the PHC pipe pile during the drilling process, reduce the risk of sticking of the drill, and improve the quality and efficiency of the drilling construction.

Detailed implementation mode

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0020] Example 1, as Figure 1 and Figure 2 shown, this embodiment discloses a construction device for PHC pipe piles of a photovoltaic module bracket, which includes a circular installation groove 1. A limiting device 2 is arranged in the middle of the inner cavity of the circular installation groove 1. A lifting device 3 is arranged on one side of the upper end of the limiting device 2. A braking device 4 is arranged in the middle of the inner cavity of the lifting device 3.

[0021] Specifically, before installing the PHC pipe pile, a hole with a certain depth needs to be drilled on the ground. Therefore, this construction device is required to drill holes on the ground. This construction device needs to be installed on a corresponding moving device. When drilling holes on the ground, the staff transports the construction device to the corresponding construction position through the relevant moving device, and then the staff adjusts the position of the braking device 4 through the limiting device 2 and the lifting device 3, so that the braking device 4 can move to a suitable position for drilling. Then the staff controls the operation of the braking device 4. At the same time, the lifting device 3 drives the braking device 4 to move downward, so that the braking device 4 performs drilling operations on the ground.

[0022] During the drilling process, if the construction device is fixed, but the drilling position does not meet the requirements, at this time, the limiting device 2 can be used to adjust the lifting device 3 and the braking device 4, as Figure 3 and Figure 4 shown. The limiting device 2 includes a fixing plate 21. The fixing plate 21 is rotatably installed in the middle of the inner cavity of the circular installation groove 1. An arc-shaped support rod 22 is arranged on one side of the outer surface of the fixing plate 21. Arc-shaped racks are arranged on the outer surfaces of the fixing plate 21 and the arc-shaped support rod 22. A gear 23 rotatably installed in the inner cavity of the circular installation groove 1 is arranged on the side of the outer surface of the arc-shaped support rod 22 far away from the lifting device 3. The gear 23 is meshed and connected with the arc-shaped racks on the outer surfaces of the fixing plate 21 and the arc-shaped support rod 22. A hand wheel 24 is arranged at the upper end of the gear 23. A dust-proof plate 25 is rotatably installed at the upper end of the circular installation groove 1.

[0023] Specifically, when the relevant mobile device transports the construction device to the corresponding position and fixes it, if the position of the construction device needs to be fine-tuned, the process of adjusting the position of the construction device through the mobile device is rather cumbersome. At this time, the staff can rotate the handwheel 24. 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 racks on the outer surfaces of the fixed plate 21 and the arc-shaped support rod 22. Then, the fixed plate 21 drives 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 above the corresponding drilling position.

[0024] To install the braking device 4 and at the same time control the up and down movement of the braking device 4, as Figure 5 and Figure 6 shown, the lifting device 3 includes a support frame 31. Limiting holes 311 are opened on both sides of the outer surface of the support frame 31. An installation plate one 33 is arranged at the lower end of the support frame 31. The lower end of the installation plate one 33 is fixedly connected to the upper end of the fixed plate 21. The outer surface of the installation plate one 33 is fixedly connected to the outer surface of the dust-proof plate 25. Hydraulic cylinders one 32 are arranged on both sides of the inner cavity of the support frame 31. Double-headed hydraulic cylinders 34 are arranged on both sides of the upper end of the installation plate one 33. The upper parts of the two double-headed hydraulic cylinders 34 are respectively rotationally connected to both sides of the upper part of the outer surface of the support frame 31. Two support telescopic rods 35 are arranged on one side of the outer surface of the support frame 31 far from the double-headed hydraulic cylinders 34 at the lower part. Mudguards 36 are arranged on both sides close to the outer surface of the support frame 31. The lower parts of the outer surfaces of the two mudguards 36 are fixedly connected to the outer side surface of the dust-proof plate 25.

[0025] 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 drilling angle of the braking device 4. When the two double-headed hydraulic cylinders 34 push the support frame 31 to the corresponding angle, the staff then adjusts the positions of the lifting device 3 and the braking device 4 through the limiting device 2.

[0026] Further, after the staff adjusts 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 one 32 to drive the braking device 4 to move downward, so that the braking device 4 drills holes in the ground.

[0027] Further, after the two double-headed hydraulic cylinders 34 push the support frame 31 to the corresponding angle, the two support telescopic rods 35 also need to be extended to support the support telescopic rods 35. During the drilling process of the braking device 4, the mudguards 36 on both sides can provide protection, greatly avoiding soil splashing onto the upper end of the limiting device 2.

[0028] During the installation of PHC pipe piles, it is necessary to first drill holes in the ground through the braking device 4, and then place the PHC pipe piles. As Figure 7 and Figure 8 shown, the braking device 4 includes a transmission member 41. On both sides of the outer surface of the transmission member 41, support blocks 44 are provided. The two support blocks 44 are slidably installed on the inner cavity surface of the support frame 31. The inner surfaces of the two support blocks 44 are respectively fixedly connected to the outer surfaces of the two hydraulic cylinders 32. On the outer surfaces of the two support blocks 44, on the sides away from each other, push plates 45 are provided. The two push plates 45 both extend to the outside of the support frame 31, and the outer surfaces of the two push plates 45 are respectively slidably connected to the inner surfaces of the two limiting holes 311. In the middle of the transmission member 41, a spiral drill bit 43 is provided. The lower part of the spiral drill bit 43 extends to the outside of the support frame 31. At the upper end of the transmission member 41, a motor 42 for transmitting kinetic energy to the spiral drill bit 43 is provided.

[0029] Specifically, when the two double-headed hydraulic cylinders 34 push the support frame 31 to the corresponding angle, since 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, the transmission member 41 also moves to a suitable angle for hole opening along with the support frame 31.

[0030] Furthermore, after 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 hole drilling operation on the ground.

[0031] Embodiment 2. Based on Embodiment 1, this embodiment further improves the discharging device 7. As Figure 1 and Figure 2 shown, on both sides of the upper part of the outer surface of the lifting device 3, driven devices 5 are provided. On the other side of the upper end of the limiting device 2, a storage frame 6 is provided. In the middle of the inner cavity of the storage frame 6, a plurality of PHC pipe pile bodies 8 are provided. On the side of the lower part of the lifting device 3 close to the storage frame 6, a discharging device 7 is provided.

[0032] Specifically, before the braking device 4 performs the hole drilling operation, the staff can place a plurality of PHC pipe pile bodies 8 in the inner cavity of the storage frame 6 for subsequent installation of the PHC pipe pile bodies 8. At the same time, place a PHC pipe pile body 8 on the upper part of the discharging device 7, and the discharging device 7 will clamp the PHC pipe pile body 8. After 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 devices 5 drive the discharging device 7 to operate.

[0033] Furthermore, when the discharging device 7 operates, the discharging device 7 can place the PHC pipe pile body 8 placed on its upper part into the dug hole, eliminating the need for workers to place it separately and improving work efficiency.

[0034] To utilize the upward power of the lifting device 3 to drive the braking device 4 to drive the discharging device 7 to operate, as Figure 9 shown, the driven device 5 includes a hydraulic frame 51. The hydraulic frame 51 is fixedly installed on the outer surface of the support frame 31. A piston 52 is arranged at the lower part of the inner cavity of the hydraulic frame 51. A spring fixedly installed on the top wall of the inner cavity of the hydraulic frame 51 is arranged at the upper end of the piston 52. A push rod 53 is arranged 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 to be used with the push plate 45 on the same side.

[0035] Specifically, during the process of the two hydraulic cylinders I 32 driving the transmission member 41 to move upward through the two support blocks 44, during the upward movement of the two support blocks 44, the two support blocks 44 will also drive the two push plates 45 to move upward respectively 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 drive the two pistons 52 to move upward respectively 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, and further cause the hydraulic oil in the inner cavity of the hydraulic frame 51 to flow into the inner cavity of the discharging device 7.

[0036] When the braking device 4 finishes drilling holes on the ground, at this time, the driven device 5 utilizes the upward force of the lifting device 3 to drive the braking device 4 to drive the discharging device 7 to operate, so that the discharging device 7 places the PHC pipe pile body 8 placed on it into the hole drilled by the braking device 4, as Figure 9 shown, the discharging device 7 includes a support handle 71. The support handle 71 is fixedly installed at the upper end of the first mounting plate 33 close to one side of the support frame 31. A pushing mechanism 72 is arranged at the upper end of the support handle 71. A clamping mechanism 73 is arranged at the upper end of the pushing mechanism 72.

[0037] Specifically, after the braking device 4 finishes drilling operations, the lifting device 3 drives the braking device 4 to move upward, and further causes the braking device 4 to drive the two driven devices 5 to operate. The hydraulic oil in the inner cavities of the two driven devices 5 will flow into the inner cavity of the pushing mechanism 72, causing the pushing mechanism 72 to drive the clamping mechanism 73 to rotate upward to make the clamping mechanism 73 stand up. After that, the clamping mechanism 73 releases the PHC pipe pile body 8 and places the PHC pipe pile body 8 into the hole drilled by the braking device 4.

[0038] To achieve the purpose of placing the PHC pipe pile body 8 placed on the upper part of the discharging device 7 into the already drilled hole, as Figure 10As shown, the pushing mechanism 72 includes a support plate 721. The support plate 721 is rotatably installed at the upper end of the support handle 71. In the middle of the inner cavity of the support plate 721, a hydraulic rod 722 is provided. On the side of the outer surface of the hydraulic rod 722 close to the support frame 31, it is rotatably installed at the upper end of the support handle 71.

[0039] Furthermore, as Figure 9 shown, the inner cavity of the hydraulic rod 722 and the inner cavities of the hydraulic frames 51 in the two driven devices 5 are respectively communicated through two hydraulic pipes.

[0040] Furthermore, as Figure 11 shown, the clamping mechanism 73 includes a support frame 731. The support frame 731 is fixedly installed at the upper end of the support plate 721. On both sides of the outer surface of the support frame 731, mounting plates II 732 are provided. On both sides of the outer surfaces of the two mounting plates II 732, clamping jaws 733 are rotatably installed. At the lower part of the outer surfaces of the two clamping jaws 733 installed on the outer surface of the same mounting plate II 732, small hydraulic cylinders II 734 are provided.

[0041] Specifically, before the braking device 4 drills holes, the staff needs to place a PHC pipe pile body 8 in the inner cavity of the storage frame 6 into the upper part of the support frame 731. Then, the staff controls the output of the two small hydraulic cylinders II 734, so that the two clamping jaws 733 connected to the same small hydraulic cylinder II 734 rotate on the outer surface of the mounting plate II 732, making the two clamping jaws 733 move towards the side close to each other, and further enabling the two clamping jaws 733 to clamp the PHC pipe pile body 8 placed in the upper part of the support frame 731.

[0042] Furthermore, when the hydraulic oil in the inner cavity of the hydraulic frame 51 is extruded under the action of the piston 52, the hydraulic oil is introduced into the inner cavity of the hydraulic rod 722 through the hydraulic pipe, making the hydraulic rod 722 push the support plate 721 to rotate upwards. Then, the hydraulic rod 722 drives the PHC pipe pile body 8 to rotate upwards through the clamping mechanism 73, making the PHC pipe pile body 8 vertical. After that, the staff controls the two small hydraulic cylinders II 734 to contract, so as to release the fixing state of the four clamping jaws 733 on the PHC pipe pile body 8. At this time, the PHC pipe pile body 8 falls into the hole drilled by the braking device 4 under the action of gravity, realizing the 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.

[0043] Furthermore, after the placing device 7 places the PHC pipe pile body 8 into the hole drilled by the braking device 4, the corresponding moving device lifts the construction device upwards, and then the corresponding moving device transports the construction device to the next construction position.

[0044] It should be noted that the specific installation methods, circuit layout connection methods, and control methods of the first hydraulic cylinder 32, double-headed hydraulic cylinder 34, and motor 42 used in the first embodiment above and the second small hydraulic cylinder 734 used in the second embodiment are all conventional designs in the prior art, and will not be elaborated in detail in the present invention.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
