In this embodiment, the number of the first passive shafts 6 is two, and the two first passive shafts 6 are respectively located on both sides of the active shaft 7. The two first passive shafts 6 are directly rotatably installed on the lifting carrier 5, and the active shaft 7 and the plurality of first passive shafts 6 transmission connection, specifically, a first pulley is fixedly sleeved on the driving shaft 7, a second pulley is fixedly sleeved on the two first passive shafts 6, the same belt 14 is sleeved on the two second pulleys and the corresponding first pulleys, the bottom ends of the two first passive shafts 6 extend to the bottom of the lifting carrier plate 5, and a plug sleeve 9 is fixedly installed, and a limited position hole is provided on the plug sleeve 9. When in use, the top of the photovoltaic spiral pile is inserted into the plug sleeve 9, and then a pin is used to pass through the limited hole and the docking socket on the photovoltaic spiral pile, so that the photovoltaic spiral pile can be reliably connected to the plug sleeve 9, and a connector 8 is fixedly installed on the top of the driving shaft 7, and a docking socket is provided on the connector 8. When in use, the sleeve on the driving head of the spiral drill is sleeved on the connector 8, and then the pin is inserted into the limited hole on the sleeve and the docking socket on the connector 8, so that the connector 8 can be reliably connected to the driving head of the spiral drill, and a high-position support mechanism for supporting the lifting carrier plate 5 is installed on the outer wall of the two side supports 1 close to each other;

[0037] Specifically, refer to Figure 3 and Figure 5Any high-position support mechanism includes a fixed block 10, a sliding support rod 11, a hand rod 12 and a first spring 13. The fixed block 10 is fixedly mounted on the side support 1 and is located on one side of the limiting slide 4. The sliding support rod 11 penetrates and is slidably mounted on the fixed block 10. The top of the sliding support rod 11 contacts the bottom of the lifting plate 5. The hand rod 12 is fixedly mounted on the end of the sliding support rod 11 away from the lifting plate 5. The first spring 13 is sleeved on the sliding support rod 11. One end of the first spring 13 is fixedly connected to the hand rod 12. The other end One end is fixedly connected to the fixed block 10. Under the holding force of the first spring 13, the sliding support rod 11 will not slide forward and backward at will, and can reliably support the lifting and lowering carrier plate 5. In order to limit the front and rear positions of the sliding support rod 11, two first limit blocks are fixedly installed on the top of the sliding support rod 11. The two first limit blocks are respectively located on both sides of the fixed block 10. Holding the hand lever 12 and pulling it forward can drive the sliding support rod 11 to slide forward, so that the sliding support rod 11 is separated from the lifting and lowering carrier plate 5, thereby releasing the restriction on the lifting and lowering carrier plate 5.

[0038] In this embodiment, in order to reduce the amount of operation by relevant personnel, an inclined sliding surface is provided at one end of the sliding support rod 11 away from the hand lever 12. When the lifting plate 5 is lifted from bottom to top, after the lifting plate 5 hits the inclined sliding surface, the sliding support rod 11 can automatically slide forward under the action of the horizontal component of the resistance force. During this process, the first spring 13 will be stretched. When the lifting plate 5 is completely raised to the top of the sliding support rod 11, the sliding support rod 11 can automatically perform a reset movement backward under the pulling force of the first spring 13, and its rear end will automatically move to the bottom of the lifting plate 5.

[0039] In this embodiment:

[0040] The photovoltaic support foundation piling device is suitable for cooperating with a spiral pile driver to drive the spiral ground piles of the photovoltaic support; in the initial state, the lifting plate 5 is located at a high position and is supported by two sliding support rods 11;

[0041] When in use, first insert the top ends of the two spiral piles into the two plug-in sleeves 9 respectively, and fix them with pins, then adjust the driving head of the spiral pile driver downward so that the sleeve on the driving head is sleeved on the connecting head 8 and fixed with a pin. Thereafter, use two construction workers to hold the two hand levers 12 respectively and pull them forward. Driven by the hand levers 12, the two sliding support rods 11 will move forward. After the two sliding support rods 11 are separated from the lifting carrier plate 5, the lifting carrier plate 5 is now supported by the driving head of the spiral pile driver. Thereafter, the driving head of the spiral pile driver moves downward, driving the lifting carrier plate 5 and the two spiral piles to move downward, and the driving head will drive the connecting head 8 to rotate during the descent process, and then drive the driving shaft 7 to rotate. The two first pulleys will drive the two belts 14 to operate during the rotation of the driving shaft 7, and then the two first passive shafts 6 will rotate. The two first passive shafts 6 will drive the corresponding plug-in sleeves 9 to rotate, so that the two spiral piles rotate, accompanied by the continuous descent of the lifting carrier plate 5 After the lifting plate 5 is lifted up to the top of the two sliding support rods 11, the two sliding support rods 11 will slide forward, and the two first springs 13 will be stretched. When the lifting plate 5 is completely lifted to the top of the two sliding support rods 11, due to the loss of the obstruction of the lifting plate 5, the two sliding support rods 11 will slide backward under the pulling force of the two first springs 13, blocking the bottom of the lifting plate 5. After that, the driving head is stopped from continuing to rise, and the pin on the sleeve of the driving head is pulled out. After the connection between the connecting head 8 and the driving head is released, the lifting plate 5 is placed on the two sliding support rods 11.

[0042] After that, the photovoltaic bracket foundation piling device is moved to the next two piling points. When moving, the photovoltaic bracket foundation piling device is first moved back a distance to allow the two already driven spiral piles to pass through the long opening on the lower connecting frame 2, and then the photovoltaic bracket foundation piling device is dragged to move to the next two piling points.

[0043] Compared with the related art, the photovoltaic support foundation piling device provided by the present invention has the following beneficial effects:

[0044] Through the arrangement of two side supports 1, lower connecting frame 2, upper connecting frame 3, lifting carrier plate 5, two first passive shafts 6, active shaft 7, connector 8, plug sleeve 9 and two high-position supporting mechanisms, when in use, the sliding support rods 11 on the two high-position supporting mechanisms can reliably support the lifting carrier plate 5, so that the lifting carrier plate 5 is in a higher position, which is convenient for the connection work between the spiral pile and the plug sleeve 9 and the connecting head 8 and the driving head of the spiral pile driver. In the process of the driving head of the spiral pile driver running and moving downward, the lifting carrier plate 5 can be driven to move downward, and the two spiral piles can be rotated in the process of moving downward, so that the two spiral piles are drilled into the soil, and the piling work of two spiral piles is completed in a single time, which has the advantage of high work efficiency; after the piling work is completed, the lifting carrier plate 5 can automatically slide forward in the process of following the rising of the driving head, and after the lifting carrier plate 5 rises to the top of the sliding support rod 11, the two sliding support rods 11 will automatically reset and block the bottom of the lifting carrier plate 5, which has the advantage of easy use.

[0045] Second embodiment:

[0046] Based on the photovoltaic support foundation piling device provided in the first embodiment of the present application, the second embodiment of the present application proposes another photovoltaic support foundation piling device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0047] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0048] Please refer to Figure 7-10In the photovoltaic support foundation piling device proposed in this embodiment, the distance between the two first passive shafts 6 is designed to be adjustable, so that within a certain range, it can meet the piling requirements of spiral piles with different spacings. Specifically, two first sliders 15 are slidably installed on the lifting and lowering carrier plate 5, and first limiting protrusions are fixedly installed on the outer walls of the front and rear sides of the first slider 15. The two limiting protrusions are slidably connected to the lifting and lowering carrier plate 5. The two first passive shafts 6 are respectively penetrated and rotatably installed on the corresponding first sliders 15. In order to adjust the distance between the two first sliders 15, the lifting and lowering carrier plate 5 is provided with a plurality of first sliders 15, and the lifting and lowering carrier plate 5 is provided with a plurality of first sliders 15. A bidirectional screw rod 16 is rotatably installed on the front side of the lowering plate 5. The bidirectional screw rod 16 passes through the two first limit protrusions located on the front side and is threadedly connected with the two first limit protrusions through two sections of external threads with opposite rotation directions. Two support blocks 17 are fixedly installed on the front side of the lifting and lowering plate 5. Avoidance openings are opened on the two support blocks 17. The bidirectional screw rod 16 passes through the two avoidance openings and is movably connected with the two avoidance openings. Second sliders 18 are slidably installed in the two support blocks 17. Second passive shafts 19 are penetrated and rotatably installed on the two second sliders 18. The two second driven shafts 19 are The moving shaft 19 is fixedly sleeved with a third pulley, and the two belts 14 are respectively sleeved on the two third pulleys. The left and right outer walls of the two second sliders 18 are fixedly installed with second limiting protrusions, and the two second limiting protrusions are slidably connected to the support block 17. The same connecting rod 21 is fixedly installed between the two second limiting protrusions on the outer wall of the side where the two second sliders 18 are close to each other. A U-shaped isolation block is fixedly installed on the front side of the lifting carrier 5. The bidirectional screw rod 16 passes through the U-shaped isolation block and is movably connected to the U-shaped isolation block. A U-shaped The U-shaped frame 20 has a one-way screw rod 22 rotatably installed in it, the connecting rod 21 passes through the U-shaped frame 20 and is movably connected to the U-shaped frame 20, the one-way screw rod 22 passes through the connecting rod 21 and is threadedly connected to the connecting rod 21. After the distance between the two first passive shafts 6 is determined, the one-way screw rod 22 can be rotated clockwise to drive the connecting rod 21 to move forward, and the connecting rod 21 drives the two second sliders 18 to move forward. The two second passive shafts 19 and the two third pulleys move with the corresponding second sliders 18, so that the two belts 14 can be tightened.

[0049] In order to facilitate the use of a wrench to screw the bidirectional screw rod 16 and the unidirectional screw rod 22, both ends of the bidirectional screw rod 16 and the end of the unidirectional screw rod 22 away from the lifting plate 5 are welded with hexagonal heads 23, and a hexagonal groove is provided in the hexagonal head 23. The provision of the hexagonal groove makes it convenient for relevant personnel to use an inner hexagonal wrench to screw the bidirectional screw rod 16 and the unidirectional screw rod 22.

[0050] In this embodiment:

[0051] In different photovoltaic foundation designs, when the distance between the spiral piles changes, the distance between the two plug sleeves 9 can be adjusted accordingly to meet the use requirements;

[0052] When adjusting the distance between the two plug-in sleeves 9, take increasing the distance as an example: first rotate the one-way screw rod 22 counterclockwise, the counterclockwise rotating one-way screw rod 22 will drive the connecting rod 21 to move backward, and under the drive of the connecting rod 21, the two second sliders 18 will gradually approach the lifting carrier plate 5, and the second passive shaft 19 and the third pulley will follow the second slider 18 to move backward, which will make the belt 14 loose, thus providing a basis for increasing the distance between the two first passive shafts 6; thereafter, rotate the bidirectional screw rod 16 clockwise, and the bidirectional screw rod 16 will drive the two first sliders 15 to move backwards during the clockwise rotation, so that the two first The distance between the sliders 15 gradually increases, and the two first sliders 15 drive the corresponding first passive shafts 6 and the plug-in sleeves 9 to move, so that the distance between the two plug-in sleeves 9 gradually increases. When the distance between the two plug-in sleeves 9 reaches the target value, the rotation of the bidirectional screw rod 16 is stopped, and then the unidirectional screw rod 22 is rotated instantaneously. According to the reverse reasoning of the above working principle, the connecting rod 21 will move forward, so that the two second sliders 18 are away from the lifting plate 5, and the two second passive shafts 19 and the two third pulleys gradually move forward, so that the two belts 14 can be gradually tightened. After the belts 14 are properly tightened, the unidirectional screw rod 22 can be stopped.

[0053] In this embodiment, through the arrangement of two first sliders 15, a bidirectional screw rod 16, two support blocks 17, two second sliders 18, two second passive shafts 19, a U-shaped frame 20, a connecting rod 21 and a one-way screw rod 22, when the one-way screw rod 22 is rotated clockwise or counterclockwise, the two second sliders 18 can be moved away from or close to the lifting plate 5, so that the belt 14 can be tightened or relaxed. In the process of rotating the bidirectional screw rod 16 clockwise or counterclockwise, the two first sliders 15 can be made to move back to back or towards each other accordingly, thereby completing the distance adjustment work between the two plug-in sleeves 9, so that the photovoltaic bracket foundation piling device can meet the piling requirements of spiral piles with different spacings within a certain range, and has the advantage of wide applicability.

[0054] Third embodiment:

[0055] Based on the photovoltaic support foundation piling device provided in the second embodiment of the present application, the third embodiment of the present application proposes another photovoltaic support foundation piling device. The third embodiment is only a preferred mode of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0056] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0057] Please refer to Figure 11-Figure 12In the photovoltaic bracket foundation piling device proposed in this embodiment, a mounting block 25 is also installed on one of the side supports 1, and a telescopic rod 26 is penetrated and slidably installed on the mounting block 25, and an L-shaped fixing frame 27 is fixedly installed on the mounting block 25, and a sliding rod 28 is penetrated and slidably installed on the L-shaped fixing frame 27. A limiting end plate 31 is fixedly installed on one end of the sliding rod 28 away from the mounting block 25, and an insulating seat 29 is fixedly installed on the end of the sliding rod 28 and the telescopic rod 26 close to each other, and a conductive block 30 is fixedly installed on the outer wall of the side where the two insulating seats 29 are close to each other. A second spring 32 is sleeved on the telescopic rod 26, and one end of the second spring 32 is fixedly connected to the corresponding insulating seat 29, and the other end is fixedly connected to the mounting block 25. A third spring 33 is sleeved on the sliding rod 28, and one end of the third spring 33 is fixedly connected to the L-shaped fixing frame 27, and the other end is fixedly connected to the corresponding insulating seat 29. The telescopic rod 26 is away from the limiting end plate 31. The end is a semicircular structure, and a sound and light alarm 37 is fixedly installed on the top of the upper connecting frame 3. Under normal circumstances, a certain gap is retained between the two conductive blocks 30, and the two conductive blocks 30 constitute a "normally open point". The sound and light alarm 37 is powered by a battery, and the battery is installed on the corresponding side support 1. The "normally open point" is connected in series in the power supply circuit of the sound and light alarm 37 through conduction. When the spiral pile is driven, after the lifting carrier plate 5 descends to a distance close to the designed drilling depth of the spiral pile, it will conflict with one end of the semicircular structure on the telescopic rod 26. Under the action of the horizontal component of the resistance force, the telescopic rod 26 will slide forward, thereby pushing the conductive block 30 on the rear side gradually close to the conductive block 30 on the front side. After the two conductive blocks 30 are in contact, the sound and light alarm 37 will be energized, thereby issuing a sound and light alarm, prompting the operator of the spiral pile driver to stop the driving head from continuing to descend in time, thereby preventing the spiral pile from being driven too deep into the soil.

[0058] In this embodiment, in order to be able to provide an alarm prompt when different pile driving depths are met within a certain range, a slide rail 24 is fixedly installed on the corresponding side support 1, and a mounting block 25 is slidably installed on the slide rail 24. Ear blocks are fixedly installed on the top and bottom of the mounting block 25, and tightening screws 34 are penetrated and threadedly installed on the two ear blocks. Contact heads 35 are rotatably sleeved on the two tightening screws 34. A strip groove is opened on the inner wall of one side of the slide rail 24 relative to the mounting block 25, and an anti-skid pad 36 is fixedly installed in the strip groove. The anti-skid pad 36 is made of rubber, and the two contact heads 35 are rotatably sleeved on the two tightening screws 34. The contact heads 35 are in contact with the anti-slip pad 36, and the tightening screw 34 is screwed clockwise to gradually approach the anti-slip pad 36. Driven by the tightening screw 34, the contact heads 35 will come into contact with the anti-slip pad 36. After applying sufficient pre-tightening force to the tightening screw 34, the sliding resistance to the mounting block 25 can be greatly increased, so that the mounting block 25 can be stably maintained at the current height position. Through the above-mentioned settings, the height position of the mounting block 25 can be adjusted according to the designed piling depth of the spiral pile, and then the distance between the telescopic rod 26 and the lifting carrier plate 5 can be adjusted appropriately.

[0059] In this embodiment, in order to prevent the telescopic rod 26 from being positioned too far back, a second limiting block is fixedly installed on the top of the telescopic rod 26 .

[0060] In this embodiment:

[0061] Through the above arrangement, the distance between the telescopic rod 26 and the lifting plate 5 can be adjusted according to the designed driving depth of the spiral pile, so that after the spiral pile is driven into the soil to a depth that reaches the designed requirement, the lifting plate 5 can push the telescopic rod 26 forward, so that the two conductive blocks 30 are in contact with each other, triggering the sound and light alarm 37 to emit a sound and light alarm;

[0062] When adjusting the height position of the telescopic rod 26, first rotate the two tightening screws 34 counterclockwise. The two tightening screws 34 will gradually move away from the slide rail 24 during the counterclockwise rotation, thereby driving the two contact heads 35 to separate from the anti-skid pad 36. In this way, the mounting block 25 is freed from restriction, and then the height position of the mounting block 25 can be adjusted upward or downward. When the distance between the telescopic rod 26 and the lifting carrier plate 5 is appropriate, the two tightening screws 34 are screwed clockwise in turn to make the two contact heads 35 tighten against the anti-skid pad 36 again, so that the mounting block 25 can be fixed and the height position of the telescopic rod 26 can be maintained. When the spiral pile is driven, As the lifting plate 5 continues to descend, the two spiral piles will gradually drill into the soil. When the drilling depth of the spiral piles approaches the designed depth, the lifting plate 5 will collide with one end of the semicircular structure on the telescopic rod 26, and will push the telescopic rod 26 to slide forward during the subsequent descent. After the drilling depth of the spiral piles reaches the designed depth, the conductive block 30 on the rear side contacts the conductive block 30 on the front side, and the sound and light alarm 37 will be powered on to emit a sound and light alarm. After the operator of the spiral pile driver observes the sound and light alarm, he can stop the driving head of the spiral pile driver from continuing to move downward in time to prevent the spiral piles from being driven too deep into the soil and affecting the installation of the subsequent bracket.

[0063] In this embodiment, by arranging the components such as the mounting block 25, the telescopic rod 26, the sliding rod 28, the two insulating seats 29, the two conductive blocks 30, the second spring 32, the third spring 33, and the sound and light alarm 37, when in use, after the lifting plate 5 touches the telescopic rod 26 downward, the two conductive blocks 30 can be brought into contact, so that the sound and light alarm 37 is activated. In this way, after the installation height of the mounting block 25 is reasonably determined according to the designed driving depth of the spiral pile, the sound and light alarm 37 can be triggered to alarm after the driving depth of the spiral pile reaches the design requirement, thereby prompting the operator of the spiral pile driver to shut down the drive head in time to avoid the spiral pile from being driven too deep into the soil and affecting the installation of the subsequent bracket; by arranging the components such as the slide rail 24, the tightening screw 34, the contact head 35, the anti-skid pad 36, etc., the height position of the mounting block 25 can be flexibly adjusted, so that the photovoltaic bracket foundation piling device can be able to give an alarm prompt at different piling depths within a certain range, further improving the convenience and flexibility of the device.
