Description
Technical Field
[0001] This utility model relates to the field of photovoltaic construction technology, specifically to a photovoltaic pipe pile unloading device. Background Technology
[0002] Photovoltaic pipe piles are the basic structures used to support photovoltaic modules in a photovoltaic power generation system. They are usually made of materials such as steel pipes or prestressed concrete pipes. They provide stable support for the photovoltaic array by being driven into or implanted in the ground, ensuring that the modules maintain a fixed angle and position under various environmental conditions to achieve efficient power generation. At the same time, they must have sufficient load-bearing capacity to resist external forces such as wind loads and snow pressure.
[0003] The bearing capacity of the natural ground is usually much lower than the pressure exerted on the ground by the outriggers of the truck crane. To meet the lifting requirements, the site needs to be hardened, which not only significantly increases costs but also has a long hardening period. During the rainy season, the hardened site is prone to softening, causing work stoppages. In addition, site subsidence may also cause safety accidents such as crane overturning. According to statistics, a considerable proportion of past photovoltaic construction accidents are related to lifting operations, most of which involve insufficient site bearing capacity. At the same time, there is a conflict between the row spacing of photovoltaic arrays and the minimum operating radius of the truck crane. In narrow sites, the truck crane cannot operate normally and can only rely on manual hooking and unhooking to complete the unloading of pipe piles. However, manual operation is inefficient, and the daily unloading volume is extremely limited. Currently, the unloading of pipe piles in photovoltaic pile foundation construction has many problems, such as high site bearing capacity requirements, limited unloading radius, and low operation efficiency.

[0009] In one optional embodiment, the first lifting claw assembly further includes a second groove formed on the rotating arm and a pin passing through the first connecting arm and the rotating arm, the pin being used to fix the rotating arm to the first groove.
[0010] In one optional embodiment, the surface of the rotating arm is provided with a plurality of mounting grooves, which are equally spaced along the vertical direction of the rotating arm.

[0022] Please refer to Figures 1-7 This utility model provides an embodiment: a photovoltaic pipe pile unloading device, including a connecting pipe 1; characterized in that: it further includes a drive assembly, a rotation adjustment assembly and an extension arm assembly installed on the connecting pipe 1, a first lifting claw assembly installed on the extension arm assembly and a detachably installed second lifting claw assembly, the input end of the extension arm assembly being connected to the output end of the drive assembly; The extension arm assembly includes a first extension arm 101 slidably disposed on the connecting pipe 1, a second extension arm 102 slidably disposed on the first extension arm 101, and a claw mounting groove 103 formed on the second extension arm 102. The drive assembly is used to drive the claw assembly below the extension arm assembly to move along a preset trajectory.
[0023] In a preferred embodiment of this utility model, the hydraulic oil pipes of the excavator are connected to the input ends of the rotary adjustment component and the drive component, respectively. The rotary adjustment component and the drive component are controlled by the hydraulic system on the excavator. The device is placed on the upper end of the photovoltaic tube. By raising and lowering the excavator's stick and boom, the extension arm is driven by the drive component to move away from and closer to each other, thereby clamping and transporting the photovoltaic tube. If the first claw component installed on the extension arm component can clamp the pipe placed on the ground, if the second claw component installed on the extension arm component can clamp the photovoltaic pipe placed on the transfer vehicle by connecting the hydraulic system to the input end of the second claw component.
[0024] In a preferred embodiment of this utility model, the drive assembly includes a fixing block 3 mounted on the connecting pipe 1, a first fixing post 301 and a second fixing post 309, a first hydraulic cylinder 302 mounted on the first extension arm 101, a rotating ring 303 mounted on the output end of the first hydraulic cylinder 302, a rotating frame 304 mounted on the first hydraulic cylinder 302, a first sprocket 305 rotatably connected to the rotating frame 304, a first chain 306 connected to the second extension arm 102 and the fixing block 3, a second sprocket 307 mounted on the second extension arm 102 and a second chain 308 connected to the second extension arm 102 and the second fixing post 309, the first chain 306 being sleeved on the rotating ring 303, and the first hydraulic cylinder 302 being used to drive the first extension arm 101. The first extension arm 101 moves horizontally towards or away from the first fixed post 301. When the first extension arm 101 moves, the second chain 308 drives the second extension arm 102 to move horizontally towards or away from the first fixed post 301. When it is necessary to clamp pipes of different lengths, one end of the first hydraulic cylinder 302 is connected to the first fixed post 301 through the rotating ring 303. By opening the first hydraulic cylinder 302 on the drive assembly, the first hydraulic cylinder 302 drives the first extension arm 101 away from the first fixed post 301. The first chain 306 is sleeved on the first sprocket 305 so that the first chain 306 pulls the second extension arm 102, thereby synchronously driving the second extension arm 102 to perform displacement work, thereby realizing the adjustment of the extension arm assembly.
[0025] In a preferred embodiment of this utility model, the rotation adjustment assembly includes a connecting seat 2 mounted on the connecting pipe 1, a rotary cylinder 201 mounted on the connecting seat 2, and a mounting bracket 202 mounted on the rotary cylinder 201. The connecting seat 2 is mounted on the output end of the rotary cylinder 201, which drives the connecting seat 2 to rotate. By mounting the mounting bracket 202 to the power adjustment output end of the excavator, the rotary cylinder 201 is opened by controlling the hydraulic system on the excavator, thereby allowing the connecting pipe 1 below to be rotated and adjusted.
[0026] In a preferred embodiment of this utility model, the first lifting claw assembly includes a first connecting arm 4 mounted on a lifting claw mounting groove 103, a first groove 401 formed in the first connecting arm 4, two rotating arms 402 rotatably connected to the first groove 401, a first lifting claw 403 connected to the first connecting arm 4, and a second lifting claw 406 mounted on the rotating arms 402. When the two second extending arms 102 approach each other, the first lifting claw 403 clamps the pipe. The first lifting claw assembly also includes a second groove 404 formed in the rotating arms 402 and a pin 405 passing through the first connecting arm 4 and the rotating arms 402. The pin 405 is used to fix the rotating arms 402. On the first groove 401, the surface of the rotating arm 402 is provided with multiple mounting slots. The mounting slots are equally spaced along the vertical direction of the rotating arm 402. When performing single-pipe clamping work, the clamping port of the pipe is placed below the two first lifting claws 403. The distance between the extension arm components is adjusted by the drive component. Then the device moves down to clamp the pipe. When multi-pipe clamping work is required, the pin 405 is taken out from the first connecting arm 4, and the two rotating arms 402 are rotated out of the first groove 401. The mounting slots on the rotating arm 402 are used to quickly thread the second lifting claw 406 to increase the number of lifting claws, thereby realizing multi-pipe clamping work.
[0027] In a preferred embodiment of this utility model, the second lifting claw assembly includes a second connecting arm 5 mounted on a lifting claw mounting groove 103, a third fixing column 501 connected to the second connecting arm 5, a second hydraulic cylinder 502 rotatably mounted on the third fixing column 501, a connecting sleeve 503 connected to the output end of the second hydraulic cylinder 502, a third groove 506 formed on the second connecting arm 5, a third lifting claw 505 rotatably connected to the third groove 506, and a third connecting arm 504 mounted on the third lifting claw 505. The third connecting arm 504 and the connecting sleeve 503 are rotatably connected to each other. 502 drives the third lifting claw 505 to rotate along the third groove 506 via the connecting sleeve 503. When it is necessary to clamp the pipe placed on the transfer vehicle, some pipes may be in contact with the placement compartment, which restricts the displacement of the extended end of the lifting claw. By installing the second lifting claw assembly, when the second hydraulic cylinder 502 is closed, its output end drives the connecting sleeve 503 to move upward, so that the third lifting claw 505 is in a vertical state and extends into the pipe clamping position. Then, the second hydraulic cylinder 502 is opened so that its output end drives the connecting sleeve 503 to move downward, thereby causing the third lifting claw 505 to rotate to a horizontal state, thus clamping the pipe.
[0028] Another embodiment based on the second gripper assembly: In actual use, the second hydraulic cylinder 502 can be replaced with a return spring, and the third lifting claw 505 can be changed to rotate clockwise. The spring pulls the third lifting claw 505, and the third lifting claw 505 folds when it touches the pipe. Then it enters the clamping position and enters the pipe to reset and unfold. Compared with the method of using the second hydraulic cylinder 502 to drive, this method is lower in cost and easier to maintain.
[0029] In a preferred embodiment of this utility model, the first extension arm 101 has limiting grooves at both ends, and the inner wall of the connecting pipe 1 has limiting blocks at both ends that are adapted to the grooves of the first extension arm 101. The second extension arm 102 has limiting grooves at both ends, and the inner wall of the first extension arm 101 has limiting blocks at both ends that are adapted to the grooves of the second extension arm 102, so as to ensure that the first extension arm 101 and the second extension arm 102 slide stably.
[0030] Through the above steps, the excavator's hydraulic oil pipes are connected to the input ends of the rotary cylinder 201 of the rotary adjustment assembly and the first cylinder 302 of the drive assembly, respectively. The rotary cylinder 201 of the rotary adjustment assembly is opened via the excavator's hydraulic system, causing the connecting seat 2 to rotate and adjust the lower connecting pipe 1 to a suitable angle. Then, the first cylinder 302 of the drive assembly is opened, causing the first extension arm 101 to move away from the first fixed column 301. The first chain 306 is sleeved on the first sprocket 305, pulling the second extension arm 102, causing the second extension arm 102 to move synchronously, thus adjusting the extension arm assembly. When performing single-pipe clamping, the pipe clamping port is placed below the first claw 403 of the two first claw assemblies. The drive assembly adjusts the distance between the extension arm assemblies to lower the device, and the first claw 403 clamps the pipe. When performing multi-pipe clamping, the pipe is clamped from the first connecting arm 4... Remove the pin 405 and rotate the two rotating arms 402 out of the first groove 401. Use the evenly distributed mounting grooves on the rotating arms 402 to quickly thread the second lifting claw 406. Increase the number of lifting claws to achieve multi-pipe clamping. When clamping the pipe placed on the transfer vehicle, install the second lifting claw assembly. The output end of the second cylinder 502 drives the connecting sleeve 503 to move upward. The third lifting claw 505 extends vertically into the pipe clamping position. Then, turn on the second cylinder 502 so that its output end drives the connecting sleeve 503 to move downward. The third lifting claw 505 rotates to a horizontal position to clamp the pipe. During the sliding process of the extension arm assembly, the limiting grooves at the front and rear ends of the first extension arm 101 cooperate with the limiting blocks at the front and rear ends of the inner wall of the connecting pipe 1. The limiting grooves at the front and rear ends of the second extension arm 102 cooperate with the limiting blocks at the front and rear ends of the inner wall of the first extension arm 101 to ensure stable sliding.
[0031] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.
[0032] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
