Description

Technical Field

[0001] This utility model relates to the field of photovoltaic pile foundation positioning technology, and in particular to a precise positioning photovoltaic pile driving device. Background Technology

[0002] Solar photovoltaic (PV) brackets are special brackets designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. They are generally made of aluminum alloy, carbon steel, and stainless steel. The base installation structure of existing PV brackets generally adopts pile foundation installation, especially for large-area outdoor PV projects, where the pile foundations generally need to penetrate several meters deep into the ground, thus requiring the use of PV piling devices.

[0003] According to a public notice (Announcement No.: CN118997151A) of a three-cable photovoltaic pile foundation positioning device, the above application uses an auxiliary rod in conjunction with an auxiliary component to further position the photovoltaic pile foundation on the ground near the pile driving position, thereby increasing the accuracy of pile driving. The movable groove is used by the hydraulic rod one to drive the movable frame to move, so that the position of the auxiliary frame can be adjusted accordingly. The auxiliary frame plays a role in auxiliary positioning at the end of the pile foundation. The hydraulic rod two controls the movement of the auxiliary frame through telescopic control to limit the end of the pile foundation.

[0004] However, in actual use, when the photovoltaic engineering piles are driven into the pre-embedded holes, the piles themselves have a certain mass and height, and are easily tilted due to deviation or external force during the pile driving process. This not only affects the pile driving work, but also the normal installation accuracy of the subsequent photovoltaic brackets. Utility Model Content

[0036] This utility model proposes a precise positioning photovoltaic piling device.

[0037] like Figures 1 to 5A precision positioning photovoltaic piling device is shown, comprising a frame 1, an impact hammer 14, and at least one positioning component 2. A vertical working channel 15 is provided within the frame 1, which is used to accommodate pile foundations. The impact hammer 14 is located on the top side of the working channel 15 and is used to impact the pile foundations located within the working channel 15. Positioning components 2 are sequentially arranged on the frame 1 along the extension direction of the working channel 15. Each positioning component 2 includes a driver 3 and a positioning frame. The driver 3 drives and connects to the positioning frame, and is used to drive the positioning frame to a preset position outside the working channel 15. The positioning frame is arranged circumferentially around the working channel 15. A positioning plate is provided on the side of the positioning frame facing the working channel 15, and a slide rail is provided around the working channel 15 on the same side. The positioning plate is slidably connected to the slide rail. Several contact wheels 4 are provided on the side of the positioning plate facing the working channel 15, and each contact wheel 4 is arranged at intervals along the circumference of the working channel 15. Each contact wheel 4 is used for vertical sliding. The positioning plate is used to support the pile foundations located within the working channel 15 through the contact wheels 4.

[0038] By setting several positioning components 2, the pile foundation located in the working channel 15 is limited and supported, which can provide a more stable support and protection effect for the pile foundation; ensure that the pile foundation remains vertical when the impact hammer 14 hits the pile foundation, and avoid the pile foundation tilting during the pile driving process, which would affect the pile driving accuracy; the pile foundation moves down continuously under the impact of the impact hammer 14, the contact wheel 4 contacts the pile foundation and assists the pile foundation to descend, reducing the wear on the side of the pile foundation. At the same time, the contact position between the contact wheel 4 and the pile foundation will also change continuously to avoid leaving too large marks on the surface of the pile foundation, which would affect the structural strength and service life of the pile foundation.

[0039] The frame 1 includes a base 11, a top frame 12, and a gantry 13. The base 11 is located on one side of the top frame 12, and the gantry 13 is located on the side of the top frame 12 away from the base 11. The working channel 15 extends along the gantry 13 toward the base 11 and passes through the top frame 12 and the base 11 in sequence. The impact hammer 14 is located on the side of the gantry 13 facing the working channel 15. A positioning component 2 is provided on the base 11 and the top frame 12 respectively.

[0040] Specifically, the two positioning components 2 are ring-shaped.

[0041] The two sets of positioning components 2 can provide good support and limit effect on the outside of the pile foundation that needs to be piled, so as to prevent it from deviating during the pile driving process. In addition, the impact hammer 14 is located on the central axis of the positioning components 2 (that is, above the working channel 15), so that the impact hammer 14 can strike the pile foundation that is limited by the positioning components 2 in the working channel 15, and give the pile foundation a vertical downward impact force, so that it enters the ground and thus realizes the pile driving work.

[0042] Several multi-section hydraulic rods 16 are arranged between the base 11 and the top frame 12, and each multi-section hydraulic rod 16 is arranged around the working channel 15.

[0043] Specifically, there are four sets of multi-section hydraulic rods 16, and the four sets of multi-section hydraulic rods 16 are arranged in a matrix array between the base 11 and the top frame 12. This allows the top frame 12 to continuously drive the gantry frame 13 and the impact hammer 14 downward as the pile foundation moves downward during pile driving, so that the pile foundation can always obtain the impact effect, thus ensuring the normal progress of photovoltaic pile driving.

[0044] The positioning frame consists of two detachable halves 21, with a slide rail located on the side of the two halves 21 facing the work channel 15; the positioning plate consists of two detachable halves 22, with one half 22 located on the slide rail of one half 21 and the other half 22 located on the slide rail of the other half 21; and several contact wheels 4 are provided on the side of each half 22 facing the work channel 15.

[0045] Specifically, both half-frame 21 and half-plate 22 are semi-circular, which facilitates the entry of the pile foundation into the working channel 15. Then, the two half-frames 21 and two half-plates 22 are combined into a ring-shaped positioning frame and a ring-shaped positioning plate to achieve the effect of supporting and limiting the pile foundation.

[0046] A limiting block 23 is provided at one end of half plate 22, and a limiting groove adapted to the limiting block 23 is provided at the other end of half plate 22. Driver 3 drives the two half plates 22 to move closer to the working channel 15, so that the limiting blocks 23 of the two half plates 22 are inserted into the limiting groove of the other half plate 22, thus assembling the two half plates 22 into a positioning plate. The two half plates 22 are aligned and assembled through the limiting blocks 23 and the limiting groove to ensure stability during support.

[0047] Two first protrusions 24 are provided on the side of the half-plate 22 away from the working channel 15. One first protrusion 24 is located near one end of the half-plate 22, and the other first protrusion 24 is located near the other end of the half-plate 22. A second protrusion and two elastic springs 26 are provided in the slide of the half-frame 21. One elastic spring 26 is located between one of the first protrusions 24 and the second protrusion, and the other elastic spring 26 is located between the other first protrusion 24 and the second protrusion. The first protrusions 24, the second protrusions, and the elastic springs 26 are all located in the slide, which can prevent the half-plate 22 from sliding into the adjacent half-frame 21, and can also buffer the descent of the pile foundation with the help of the elastic springs 26.

[0048] A connecting rod 25 is also provided on the side of the half-plate 22 opposite to the working channel 15. The connecting rod 25 passes through the second protrusion and is slidably connected to the second protrusion. One end of the connecting rod 25 is connected to one of the first protrusions 24, and the other end of the connecting rod 25 is connected to the other first protrusion 24. The connecting rod 25 is located between the two first protrusions 24. Two elastic springs 26 are respectively sleeved on the connecting rod 25. The setting of the connecting rod 25 can further improve the stability of the half-plate 22 when rotating and prevent the elastic springs 26 from disengaging.

[0049] The actuator 3 includes two first cylinders 31, which are mounted on the frame 1 and symmetrically arranged along the working channel 15. The output ends of the two first cylinders 31 face the working channel 15 respectively. The output end of one first cylinder 31 drives and connects to the adjacent half-frame 21, and the output end of the other first cylinder 31 drives and connects to the adjacent half-frame 21. The two first cylinders 31 operate and position the two half-frames 21 to ensure the support effect of the two pairs of half-frames on the pile foundation.

[0050] The driver 3 also includes two second cylinders 32 and two connecting rods 33. The two second cylinders 32 are disposed on the frame 1 and are symmetrically arranged along the working channel 15. The output ends of the two second cylinders 32 are respectively arranged facing the working channel 15. The output end of one second cylinder 32 is hinged to one end of one connecting rod 25, and the other end of the connecting rod 25 is hinged to the adjacent half frame 21. The output end of the other second cylinder 32 is hinged to the other end of the other connecting rod 25, and the other end of the connecting rod 25 is hinged to the adjacent half frame 21. One second cylinder 32 and the adjacent first cylinder 31 are arranged vertically spaced apart. The other second cylinder 32 and the adjacent first cylinder 31 are arranged vertically spaced apart.

[0051] The first cylinder 31, the second cylinder 32, and the connecting rod 33 form a relatively stable triangle between the base 11 and the connecting rod 33. By synchronously controlling the start of the first cylinder 31 and the second cylinder 32, the positioning frame can move horizontally toward the working channel 15 and fit against the outer surface of the pile foundation, ensuring the horizontal stability of the positioning frame.

[0052] Several balls 41 are provided on the contact surface of the contact wheel 4 facing the working channel 15.

[0053] The contact surface of the contact wheel 4 is configured as an inwardly concave arc groove 42 that is adapted to the outer surface of the pile foundation, and the contact wheel 4 is arranged vertically, so that the contact wheel 4 will not cause excessive wear or movement interference to the outer surface of the pile foundation that is continuously descending due to impact.

[0054] Ball bearings 41 are movably mounted on the contact surface of the contact wheel 4, and there are two sets of ball bearings 41. The two sets of ball bearings 41 are located on both sides of the central axis of the contact wheel 4, and the two sets of ball bearings 41 are staggered. Each set of ball bearings 41 contains several ball bearings 41 bodies arranged in a circumferential array. This allows the contact wheel 4 to contact the pile foundation surface by means of the ball bearings 41. Even if the pile foundation moves down continuously under the impact of the impact hammer 14, the staggered ball bearings 41 prevent excessive wear between the contact surface of the contact wheel 4 and the pile foundation. At the same time, the contact position will continuously change to avoid leaving excessive marks on the pile foundation surface, which would affect the structural strength and service life of the pile foundation.

[0055] The work process is as follows:

[0056] When using it, first open the pre-embedded holes at the location where the photovoltaic pile foundation needs to be buried, then place the frame 1 on the pre-embedded holes, and align the center of the working channel 15 with the axis of the pre-embedded holes.

[0057] Next, position the frame 1 on the ground, and then use external equipment to lift the pile foundation end to be aligned with the pre-embedded hole. At this time, start each first cylinder 31 and each second cylinder 32 to move the positioning frame in the horizontal direction, and finally position the pile foundation at the center of the working channel 15, and ensure that the pile foundation is in a vertical state.

[0058] Start the multi-section hydraulic rod 16 to move the gantry frame 13 and the impact hammer 14 to a suitable position at the top of the pile foundation; then start the impact hammer 14 so that the impact hammer 14 continuously generates downward impact force on the pile foundation, and in conjunction with the continuously retracting multi-section hydraulic rod 16, control the top frame 12 to continuously and slowly move down, thereby completing the pile driving work.

[0059] During this process, two positioning components 2 are set up. When the two positioning frames on the frame 1 approach each other and dock, the half plates 22 in the two positioning frames approach each other and assemble into a ring-shaped positioning plate, so that the positioning frame can provide a more stable support and protection effect for the pile foundation, and avoid the pile foundation from tilting during the pile driving process, which would affect the pile driving accuracy.

[0060] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
