Description

Technical Field

[0001] This utility model relates to photovoltaic grouting piles, and in particular to a rapid positioning device for photovoltaic grouting piles in mountainous areas. Background Technology

[0002] In mountainous photovoltaic (PV) projects, it is often necessary to effectively transfer the load on the PV support structure to a stable foundation using cast-in-place piles to ensure the long-term stable operation of the PV project. Therefore, the construction quality of the cast-in-place piles directly affects the overall performance and service life of the PV project. Currently, the positioning methods for cast-in-place piles typically employ surveying instruments such as total stations or theodolites. However, these methods are ill-suited to the dense vegetation and significant terrain variations characteristic of mountainous environments, making it difficult to guarantee positioning accuracy during construction and thus impacting the quality of the cast-in-place piles. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a rapid positioning device for mountain photovoltaic grouting piles that is compact in structure, easy to install, low in construction cost, and can achieve rapid and accurate positioning of grouting piles.

[0004] This utility model provides a rapid positioning device for mountain photovoltaic cast-in-place piles, comprising:

[0005] The support frame, serving as a support and installation carrier, consists of two parallel supports. The support frame includes a crossbeam 3 and legs 1 at both ends of the crossbeam. The height of the legs 1 is adjustable, and the distance from the ground to the end of the crossbeam 3 can be adjusted.

[0006] The positioning frame includes a positioning plate 4 mounted on the crossbeam 3. The positioning plate 4 has an opening 40 for the grouting pile 8 to pass through. The upper end of the positioning plate 4 is equipped with a first positioning rod 5 and a second positioning rod 6 that are perpendicular to each other. There are two first positioning rods 5 and two second positioning rods 6, which are parallel to each other. A positioning area is formed between the two first positioning rods 5 and the two second positioning rods 6, which can position the grouting pile 8. The distance between the two first positioning rods 5 and the two second positioning rods 6 is adjustable, and the diameter of the inscribed circle of the positioning area can be adjusted.

[0007] This application employs an adjustable-height outrigger structure, perfectly adapting to complex mountainous terrain. By adjusting the distance between the outriggers and the crossbeam, the ground clearance of both ends of the crossbeam can be flexibly adjusted. This is crucial for uneven mountainous terrain, ensuring that the positioning frame (positioning plate) is always horizontal or at the required working height, providing a stable foundation platform for precise positioning. It eliminates the need for extensive ground leveling, significantly reducing initial earthwork. The adjustable-spacing positioning rod design accommodates the needs of piles with different diameters. After adjustment, the pile is constrained within the positioning area, its center naturally aligned with the center of the positioning area, effectively preventing pile offset. Its convenient operation enables rapid and accurate positioning, significantly improving construction efficiency. The adjustable diameter of the tangent circle within the positioning area is one of its core advantages, allowing the same device to be used for the construction of piles with various diameters without replacing major components, improving the equipment's versatility and utilization rate, and reducing equipment investment costs.

[0008] Furthermore, the support frame is fixed to the positioning plate 4 by bolts, and the distance between the two support frames is adjustable; it is easy to adjust, can improve the adaptability to terrain, can dynamically adjust the span according to the actual slope shape, ensure the overall stable erection of the device, and has good flexibility of use.

[0009] Furthermore, mounting bases 2 are fixed at both ends of the crossbeam 3, and the support legs 1 are fixed at both ends of the crossbeam 3 through the mounting bases 2. The mounting bases 2 are fixed to the crossbeam 3 by bolts, and the distance between the two mounting bases 2 is adjustable; this also improves the adaptability to terrain and enhances the flexibility of use.

[0010] Furthermore, the mounting base 2 includes a first plate 21 that can fit against the lower surface of the crossbeam 3. The two ends of the first plate 21 are bent downward to form a second plate 22 that can fit against the side wall of the support leg 1. The support leg 1 is installed between the two second plates 22. The first plate 21 is provided with a first mounting hole I 210 for connecting with the crossbeam 3, and the second plate 22 is provided with a second mounting hole I 220 for connecting with the support leg 1. The first plate contacts the lower surface of the crossbeam, which can realize the vertical pressure transmission, improve the uniformity of force distribution, and prevent the crossbeam from deforming. The second plate 22 forms a clamping structure, which can form a lateral rigid constraint, effectively resist the horizontal force in mountain construction, form a surface contact and wrapping structure, significantly improve the bending and torsional resistance of the support frame, and prevent the support frame from deforming under force and causing positioning inaccuracy.

[0011] Furthermore, the side wall of the support leg 1 is provided with a second mounting hole II 110 corresponding to the second mounting hole I 220. There are multiple second mounting holes II 110 arranged sequentially along the length direction of the support leg 1. They form different height levels. According to different terrains, the appropriate mounting hole can be selected to flexibly adjust the height of the support leg (beam) to ensure that the device can be stably erected on different slopes. The structure is simple, the manufacturing cost is low, and the adjustment is convenient and quick.

[0012] Furthermore, the lower surface of the end of the crossbeam 3 is provided with a first mounting hole II 31 corresponding to the first mounting hole I 210. There are multiple first mounting holes II 31 arranged sequentially along the length direction of the crossbeam 3. They form different width positions. According to different terrains, the appropriate mounting hole can be selected to flexibly adjust the distance between the two legs. The structure is simple, the manufacturing cost is low, and the adjustment is convenient and quick.

[0013] Furthermore, the two sides of the first plate 21 are bent upward to form a first reinforcing part 211. The crossbeam 3 is located between the two first reinforcing parts 211 and can achieve radial limiting of the crossbeam 3. On the one hand, it can improve the overall structural strength of the mounting base and extend its service life; on the other hand, it forms a physical guard to prevent the crossbeam from radially shifting. It can withstand lateral forces and avoids the force being directly borne by the bolts, thus improving the service life of the connectors. At the same time, the forming limiting structure can realize the rapid positioning and assembly of the crossbeam, improving assembly efficiency.

[0014] Furthermore, the positioning plate 4 is provided with a third mounting hole 41 for installing the first positioning rod 5 and a fourth mounting hole 42 for installing the second positioning rod 6. There are multiple third mounting holes 41 arranged sequentially along the length direction of the second positioning rod 6, and there are multiple fourth mounting holes 42 arranged sequentially along the length direction of the first positioning rod 5. It is easy to process, has low manufacturing cost, can realize rapid adjustment of the position of the first positioning rod 5 and the second positioning rod 6, and the adjustment is convenient, labor-saving, and easy to operate.

[0015] Furthermore, the second positioning rod 6 is mounted on the positioning plate 4 via a corner bracket 7 and is located above the first positioning rod 5. This enables a layered positioning structure between the first and second positioning rods in the vertical direction, avoiding mutual interference.

[0016] Furthermore, the first positioning rod 5 and the second positioning rod 6 are purlins; they are lightweight, achieving a lightweight design, and at the same time, they have pre-drilled holes for easy installation and adjustment, resulting in low operating costs, light weight, and high strength.

[0017] Furthermore, the upper end of the support leg 1 is provided with a relief groove 111 for avoiding bolts, providing relief space for bolts, avoiding false tightening caused by improper installation, ensuring connection strength, and facilitating assembly.

[0019] This utility model of a rapid positioning device for mountain photovoltaic cast-in-place piles adopts an adjustable-height outrigger structure, perfectly adapting to complex mountainous terrain. By adjusting the distance between the outriggers and the crossbeam, the ground clearance of both ends of the crossbeam can be flexibly adjusted, which is crucial for uneven mountainous terrain.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] See Figures 1-8 This utility model provides a rapid positioning device for photovoltaic grouting piles in mountainous areas, which is used to quickly and accurately position photovoltaic grouting piles in mountainous areas. It includes a support frame and a positioning frame.

[0030] The support frame serves as a support and installation carrier, fixedly installed on the mountainside and used to install the positioning frame. As a basic structure, it ensures the stability and load-bearing capacity of the overall device. There are two support frames, arranged in parallel. The support frame includes a crossbeam 3 and legs 1. Mounting seats 2 are fixed at both ends of the crossbeam 3. The legs 1 are fixed to both ends of the crossbeam 3 through the mounting seats 2. The distance between the legs 1 and the mounting seats 2 is adjustable, which can adjust the overall height of the legs 1 and thus adjust the distance of the ends of the crossbeam 3 from the ground to adapt to installation on mountain slopes with different inclines.

[0031] The positioning frame is mounted on two support frames and includes a positioning plate 4. The positioning plate 4 is rectangular and is mounted on two crossbeams 3 of the support frame. An opening 40 is provided on the positioning plate 4 to allow the cast-in-place pile 8 to pass through. The diameter of the opening 40 is larger than the diameter of the cast-in-place pile. A first positioning rod 5 and a second positioning rod 6 are installed on the upper end of the positioning plate 4. The first positioning rod 5 and the second positioning rod 6 are both parallel to the positioning plate 4 and perpendicular to each other. There are two first positioning rods 5 and two second positioning rods 6. The two first positioning rods 5 and the two second positioning rods 6 are parallel to each other. A positioning area is formed between the two first positioning rods 5 and the two second positioning rods 6, which can position the cast-in-place pile 8. The distance between the two first positioning rods 5 and the distance between the two second positioning rods 6 are adjustable, thereby allowing adjustment of the inner circle diameter of the positioning area.

[0032] This application employs an adjustable-height outrigger structure, perfectly adapting to complex mountainous terrain. By adjusting the distance between the outriggers and the crossbeam, the ground clearance of both ends of the crossbeam can be flexibly adjusted. This is crucial for uneven mountainous terrain, ensuring that the positioning frame (positioning plate) is always horizontal or at the required working height, providing a stable foundation platform for precise positioning. It eliminates the need for extensive ground leveling, significantly reducing initial earthwork. The adjustable-spacing positioning rod design accommodates the needs of piles with different diameters. After adjustment, the pile is constrained within the positioning area, its center naturally aligned with the center of the positioning area, effectively preventing pile offset. Its convenient operation enables rapid and accurate positioning, significantly improving construction efficiency. The adjustable diameter of the tangent circle within the positioning area is one of its core advantages, allowing the same device to be used for the construction of piles with various diameters without replacing major components, improving the equipment's versatility and utilization rate, and reducing equipment investment costs.

[0033] In this application, the positioning plate 4 is generally rectangular in structure. It has a third mounting hole 41 and a fourth mounting hole 42. The third mounting hole 41 is used to install the first positioning rod 5, and the fourth mounting hole 42 is used to install the second positioning rod 6. These holes are respectively located at the four corners of the positioning plate 4 and are symmetrically arranged. There are multiple third mounting holes 41, arranged sequentially along the length of the second positioning rod 6, preferably at equal intervals. There are also multiple fourth mounting holes 42, arranged sequentially along the length of the first positioning rod 5, preferably at equal intervals. This design is easy to process, has low manufacturing cost, enables rapid adjustment of the positions of the first positioning rod 5 and the second positioning rod 6, and is convenient and labor-saving to assemble and adjust, with low operational difficulty.

[0034] The crossbeam 3 is a strip structure. A sixth mounting hole 32 for connecting with the positioning plate 4 is provided on the crossbeam 3, which penetrates the upper and lower surfaces of the crossbeam 3. In order to improve assembly efficiency, in this application, the sixth mounting hole 32 can correspond to the fourth mounting hole, which facilitates overall assembly.

[0035] In this application, the first positioning rod 5 is directly fixed to the positioning plate 4 by bolts, while the second positioning rod 6 is installed on the positioning plate 4 by angle brackets 7. It is located above the first positioning rod 5, which can realize the layered positioning structure of the first positioning rod and the second positioning rod in the vertical direction to avoid mutual interference. In addition, the first positioning rod 5 and the second positioning rod 6 in this application are purlins, which are lightweight and realize lightweight design. At the same time, they have pre-drilled holes for easy installation and adjustment, resulting in low cost, light weight and high strength.

[0036] To further enhance adaptability to mountainous terrain, in this application, the support frame is fixed to the positioning plate 4 with bolts, and the distance between the two support frames is adjustable. This adjustment is convenient, improving terrain adaptability and allowing for dynamic adjustment of the span according to the actual slope shape. For example, on steep slopes, the distance between the support frames can be shortened to prevent instability of the device's center of gravity due to excessive span. Similarly, in uneven areas, the distance can be widened to cross gullies or protrusions, ensuring the overall stable erection of the device. This adjustment is convenient and offers good flexibility. Simultaneously, in this application, the mounting base 2 is fixed to the crossbeam 3 with bolts, and the distance between the two mounting bases 2 is adjustable. This also enhances terrain adaptability and improves flexibility, allowing for adjustment of the lateral and longitudinal distances of the four legs according to different mountainous terrains. This demonstrates strong adaptability and versatility.

[0037] In this application, the mounting base 2 includes a first plate 21, which is a rectangular structure that can fit against the lower surface of the crossbeam 3. The two ends of the first plate 21 are bent downwards at 90 degrees to form a second plate 22. The second plate 22 can fit against the second plate 22 on the side wall of the support leg 1. The support leg 1 is installed between the two second plates 22. A first mounting hole I 210 is provided on the first plate 21 for connecting to the crossbeam 3 by bolts. A second mounting hole I 220 is provided on the second plate 22 for connecting to the support leg 1 by bolts. The first plate contacts the lower surface of the crossbeam, which can realize the vertical pressure transmission, improve the uniformity of force distribution, and prevent the crossbeam from deforming. The second plate 22 forms a clamping structure, which can form a lateral rigid constraint, effectively resisting the horizontal force in mountain construction, forming a surface contact and wrapping structure, significantly improving the bending and torsional resistance of the support frame, and preventing the support frame from deforming under force and causing positioning inaccuracy.

[0038] Specifically, the two sides of the first plate 21 are bent upwards at 90 degrees to form two first reinforcing parts 211. The crossbeam 3 is located between the two first reinforcing parts 211, thereby achieving radial limiting of the crossbeam 3. On the one hand, this can improve the overall structural strength of the mounting base and extend its service life; on the other hand, it forms a physical stop to prevent the crossbeam from radially shifting. It can withstand lateral forces and avoids the force being directly borne by the bolts, thus improving the service life of the connecting parts. At the same time, the limiting structure can realize the rapid positioning and assembly of the crossbeam, improving assembly efficiency. The two sides of the second plate 22 are bent inwards or outwards to form second reinforcing parts 221, which can improve the overall structural strength of the mounting base 2. When bent inwards, it can limit the legs, realize the rapid positioning and installation of the mounting base, and form a limiting part, which can withstand horizontal forces, improve structural strength, and extend service life.

[0039] Meanwhile, a second mounting hole II110 corresponding to the second mounting hole I220 is provided on the side wall of the support leg 1. There are multiple second mounting holes II110, which are arranged sequentially along the length direction of the support leg 1. Preferably, they are arranged at equal intervals along the length direction of the support leg. They form different height levels. According to different terrains, the appropriate mounting hole is selected to flexibly adjust the height of the support leg (beam) to ensure that the device can be erected stably on different slopes. The structure is simple, the manufacturing cost is low, and the adjustment is convenient and quick.

[0040] In this application, a clearance groove 111 is provided at the upper end of the support leg 1 to allow clearance for the bolt, which is the bolt connecting the mounting base and the crossbeam. This provides clearance space for the bolt, avoids interference during installation, and thus avoids false tightening caused by improper installation. This ensures connection strength and facilitates assembly.

[0041] The outrigger 1 in this application includes an outrigger body 11, which is made of I-beams. Second mounting holes II 110 for connecting to mounting bases are symmetrically arranged on both sides of the outrigger body 11. A base plate 12 is provided at the lower end of the outrigger body 11, and a fifth mounting hole is provided on the base plate 12 for connecting to the ground. A reinforcing rib 13 is provided between the side wall of the outrigger body 11 and the base plate 12. It has low manufacturing cost and high structural strength.

[0042] A first mounting hole II 31 corresponding to the first mounting hole I 210 is provided on the lower surface of the end of the crossbeam 3. There are multiple first mounting holes II 31, which are arranged sequentially along the length direction of the crossbeam 3. Preferably, they are arranged at equal intervals along the length direction of the crossbeam. They form different width levels. According to different terrains, appropriate mounting holes are selected to flexibly adjust the distance between the two legs. The structure is simple, the manufacturing cost is low, and the adjustment is convenient and quick.

[0043] This utility model of a rapid positioning device for mountain photovoltaic cast-in-place piles adopts an adjustable-height outrigger structure, perfectly adapting to complex mountainous terrain. By adjusting the distance between the outriggers and the crossbeam, the ground clearance of both ends of the crossbeam can be flexibly adjusted, which is crucial for uneven mountainous terrain. It ensures that the positioning frame (positioning plate) is always horizontal or at the required working height, providing a stable foundation platform for accurate positioning. It eliminates the need for extensive ground leveling, significantly reducing the amount of earthwork required upfront. The adjustable lateral and longitudinal widths of the outriggers enhance terrain adaptability, dynamically adjusting the span according to the actual slope shape to ensure stable overall installation and high flexibility.

It is applicable to the construction of cast-in-place piles of various diameters, improving the equipment's versatility and utilization rate. Loading, unloading, and adjustment are convenient and labor-saving.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
