Description

Technical Field

[0001] This invention relates to the field of vibratory piling technology, specifically a novel photovoltaic support foundation piling device. Background Technology

[0002] Photovoltaic brackets are an indispensable part of solar photovoltaic power generation systems. They can fix solar panels and ensure their stability and safety. In the traditional mode of installation, the bracket foundation is usually driven first, then the bracket foundation is welded on it, and then the bracket track used to lay the photovoltaic panels is installed to complete the construction of the photovoltaic bracket.

[0003] Vibratory pile drivers consist of a vibrator, a power mechanism, and a pile clamp. During operation, a crane is typically used to control the position and orientation of the vibratory pile driver, along with the pile clamp to hold the photovoltaic support structure before transporting it to the designated location for pile driving. However, traditional vibratory pile drivers are less convenient when lifting the pile using the pile clamp, requiring a considerable amount of time for connection. Furthermore, if the work site is damp (e.g., after rain when the ground is not dry), a large amount of congealed soil can easily accumulate inside the clamping tube, hindering stable pile holding.

[0004] Therefore, a novel photovoltaic support foundation piling device is provided to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a novel photovoltaic support foundation piling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel photovoltaic support foundation piling device includes a pile frame, on which a vibratory pile driver is mounted, and on which a connecting frame is mounted. A clamping tube is mounted on the lower side of the pile frame, and a positioning structure is provided on the lower side of the clamping tube to facilitate the entry of the pile into the clamping tube. A cleaning structure is provided inside the clamping tube to clean the sludge inside the clamping tube. A clamping structure is provided on the outer side of the clamping tube to assist in clamping the pile inside the clamping tube.

[0009] As a further embodiment of the present invention, guide claws are fixedly connected to both sides of the guide block.

[0010] As a further embodiment of the present invention: the cleaning structure includes an oil cavity, the oil cavity being formed in the inner wall of the clamping tube, a transmission rod being fixedly connected to the upper side of the guide block, the transmission rod being slidably connected inside the oil cavity and fixedly connected to a movable plug.

[0011] As a further embodiment of the present invention: a fixed rod is fixedly connected inside the oil cavity, the movable plug is slidably connected to the fixed rod, and a return spring is sleeved on the fixed rod.

[0012] As a further embodiment of the present invention: a fixed cylinder is fixedly connected inside the clamping tube, a movable rod is slidably connected inside the fixed cylinder, a plurality of crushing blocks are hinged to the lower side of the movable rod via a connecting rod, a plurality of arc-shaped grooves are formed on the inner wall of the clamping tube, and the crushing blocks are slidably connected inside the arc-shaped grooves.

[0013] As a further embodiment of the present invention: the oil cavity is filled with hydraulic oil, and an oil guide pipe is fixedly connected to and penetrates the fixed cylinder.

[0014] As a further embodiment of the present invention: the cross-section of the broken block is triangular, and the broken block is fitted to the curved surface of the arc groove.

[0015] As a further embodiment of the present invention: the clamping structure includes a clamping cylinder, the clamping cylinder is mounted on the pile frame, a clamping block is installed at the output end of the clamping cylinder, auxiliary clamping blocks are fixedly connected to both sides of the clamping block, and a plurality of clamping holes and slots are provided through the surface of the clamping tube, the auxiliary clamping blocks and the clamping blocks are mating components with the clamping holes and slots.

[0016] As a further embodiment of the present invention: the clamping tube is internally fixedly connected with a plurality of limiting blocks, the limiting blocks being located on the lower side of the connecting rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This piling device uses a crane to control the movement of a vibratory pile driver and a clamping tube below it to lift the foundation piles of the photovoltaic support system to be pre-embedded (piled). Firstly, a guide block ensures quick alignment of the clamping tube with the pile tube upon contact, facilitating the subsequent rapid insertion of the clamping tube onto the photovoltaic support pile. This reduces the time spent clamping and lifting the pile before piling, improving the efficiency of photovoltaic support pre-embedding. Furthermore, the buffering force generated when the guide block in the positioning structure contacts the pile reduces the impact force when the vibratory pile driver moves downwards to contact the pile. This prevents excessive damage to the photovoltaic support piles before installation.

[0019] 2. In this piling device, if the soil is damp, dust on the pile surface will be retained on the inner wall of the clamping tube during the clamping action. This dust can solidify during clamping and lifting, affecting the stability of the pile. The cleaning structure, with its breaking blocks, cleans the inside of the clamping tube when the guide block contacts the pile tube, preventing large clumps of soil from accumulating inside and hindering the pile tube from entering. This achieves stable clamping of the pile during the pre-embedding process of the photovoltaic support pile. Attached Figure Description

Detailed Implementation

[0031] Please see Figure 1 A novel photovoltaic (PV) support foundation piling device includes a pile frame 1, on which a vibratory pile driver 7 is mounted. A connecting frame 8 is mounted on the vibratory pile driver 7. The vibratory pile driver 7 drives the pile frame 1 to vibrate, and the connecting frame 8 can be hoisted by a crane, suspending the vibratory pile driver 7 and the pile frame 1. A clamping pipe 2 is installed on the lower side of the pile frame 1. The diameter of the clamping pipe 2 is slightly larger than the diameter of the pile body, facilitating the clamping of the pile body. Most of the piles for PV cable supports are cylindrical. During the piling installation of the PV support, the embedment points are first marked on the ground. Then, the PV support is transported to the designated location, and a crane (not shown in the diagram) is used to control the vibratory pile driver to hoist each PV support. When pile driving is required, the photovoltaic support frame, which has fallen (lay horizontally on the ground), is first lifted by the clamping pipe 2 and brought to a vertical position. Then, a crane is used to control its movement, transporting it to the marked point. Finally, the vibratory pile driver is activated to pre-embed the piles perpendicular to the ground. During this process, the vibratory pile driver 7 drives the pile to vibrate, and the force of the vibration is transmitted to the ground, causing the soil to liquefy. The pile gradually overcomes the soil resistance and is able to penetrate into the soil, completing the pile driving step. The vibratory pile driver 7 uses an electric motor as a power source to drive the internal vibrator to vibrate, thus generating vibration. The vibrator adopts a synchronous counter-rotating eccentric block structure, mainly composed of a vibration box 71, an eccentric block 72, an eccentric block rotation shaft 73, transmission gears, pulleys, etc. When the eccentric block on the disc rotates, centrifugal force is generated, thus producing vibration. The above-described pile driving process of the vibratory pile driver is existing technology and will not be described in detail here.

[0032] In the process of clamping the pile body, the clamping tube 2 may encounter problems such as high clamping difficulty and instability. Therefore, the following improvements have been made in this application.

[0033] like Figure 2 andFigure 3 As shown, a positioning structure 3 is provided on the lower side of the clamping tube 2. The positioning structure 3 includes a guide block 301. Two sets of sliding rods 303 are fixedly connected to one side of the guide block 301. A fixed frame 304 is fixedly connected to the outer side of the clamping tube 2. The sliding rods 303 are slidably connected inside the fixed frame 304. Guide claws 302 are fixedly connected to both sides of the guide block 301. In this embodiment, in order to enable the operator to quickly complete the hoisting of the pile body by the clamping tube 2, the guide block 301 is first attached to the edge of the pile body tube. When the guide block 301 is attached to the clamping tube 2, under the gravity of the pile frame 1 and the clamping tube 2 itself, the guide block 301 will move closer to the clamping tube 2 and move on the clamping tube 2 through the sliding rods 303, so that the overall length of the clamping tube 2 and the guide block 301 becomes shorter. This setting is to enable the operator to quickly determine the position where the clamping tube 2 should be placed at the edge of the pile body tube, reducing the difficulty of operation for the operator.

[0034] After the guide block 301 is aligned with the clamping tube 2, the clamping tube 2 is tilted so that one side of it is in contact with the ground. At this point, the clamping tube 2 is initially aligned with the pile (there is still a deviation between the centerline of the pile and the clamping tube 2). Then, the crane is started to move the clamping tube 2 towards the pile, and the vibrating motor is started at the same time. Under the action of the vibrating motor, the pile extending into the clamping tube 2 will continuously correct its angle under the action of the inner wall of the clamping tube 2, so that its centerline is parallel to the centerline of the clamping tube 2. Therefore, under the dual power, the clamping tube 2 can be fitted onto the pile.

[0035] Furthermore, such as Figure 4 As shown, when the pile enters the clamping tube 2, it undergoes two steps: correction and movement. When the vibratory motor and crane move, the front end of the pile enters the clamping tube 2. If the pile and clamping tube 2 are not fully aligned, the vibratory motor and crane will drive the clamping tube 2 and pile to correct their positions, ensuring complete alignment. Then, the crane is moved again and the vibratory motor is started, allowing the pile to fully enter the clamping tube 2. The guide claw 302, when the clamping tube 2 tilts, can fully conform to the upper side of the pile (when the pile falls to the ground). That is, when the clamping tube 2 tilts, the guide block 301 moves towards the pile under the rebound force (restoring its initial position), increasing the contact area between the guide block 301 and the pile, and increasing the number of points of force application. Thus, when the vibratory motor is started, the guide claw 302 improves the correction efficiency of the clamping tube 2, allowing the pile and clamping tube 2 to quickly align.

[0036] The clamping tube 2 is equipped with a cleaning structure inside. The cleaning structure cleans the sludge inside the clamping tube 2. When the clamping tube 2 is working, a large volume of solidified mud will adhere to the inside. The solidified mud will prevent the pile from entering the inside of the clamping tube 2 and will also affect the stability during the clamping process. The cleaning structure will destroy the large volume of solidified mud inside the clamping tube 2, so that it can no longer adhere to the inside of the clamping tube 2. Therefore, it plays a cleaning role inside the clamping tube 2.

[0037] like Figure 5 and Figure 6 , Figure 7 As shown, the cleaning structure includes an oil chamber 4, which is located on the inner wall of the clamping tube 2. A transmission rod 401 is fixedly connected to the upper side of the guide block 301. The transmission rod 401 is slidably connected inside the oil chamber 4 and a movable plug 402 is fixedly connected thereto. A fixed rod 404 is fixedly connected inside the oil chamber 4. The movable plug 402 is slidably connected to the fixed rod 404. A return spring 403 is sleeved on the fixed rod 404. A fixed cylinder 5 is fixedly connected inside the clamping tube 2. A moving rod 501 is slidably connected inside the fixed cylinder 5. Multiple breaking blocks 503 are hinged to the lower side of the moving rod 501 through a connecting rod 502. Multiple arc-shaped grooves 504 are provided on the inner wall of the clamping tube 2. The breaking blocks 503 are slidably connected inside the arc-shaped grooves 504. Hydraulic oil is provided inside the oil chamber 4. An oil guide pipe 405 is fixedly connected to and runs through the fixed cylinder 5.

[0038] Therefore, during crane lifting, the clamping pipe 2 needs to be controlled to move vertically downwards towards one end of the photovoltaic support. After the clamping pipe 2 is lowered, its opening needs to be aligned with one end of the photovoltaic support. At this point, the photovoltaic support is then connected to the clamping pipe 2 to achieve the purpose of clamping the photovoltaic support. When the crane controls the clamping pipe 2 to fall and contact the photovoltaic support, the guide block 301 on the clamping pipe 2 will move upwards, causing hydraulic oil to transfer and absorb energy, thus providing a buffering effect and preventing the clamping pipe 2 from directly falling and contacting the fiber optic cable support pile, thereby preventing damage to the pile.

[0039] As described above, when the guide block 301 is in contact with the clamping tube 2, the guide block 301 will move upward under the gravity of the clamping tube 2 itself. When the guide block 301 moves upward, it will cause the movable plug 402 to move inside the oil chamber 4 through the transmission rod 401. When the movable plug 402 moves upward, it will push the hydraulic oil in the oil chamber 4 upward. The hydraulic oil will enter the interior of the fixed cylinder 5 through the oil guide pipe 405. Then, the hydraulic oil inside the fixed cylinder 5 will push the moving rod 501 downward. The moving rod 501 will drive the crushing block 503 to move along the arc groove 504. The crushing block 503 will move downward in an arc along the arc groove 504, crushing the large volume of soil adhering to the inside of the clamping tube 2. After being crushed, the large volume (dried) soil can no longer adhere to the inner wall of the clamping tube 2, and will fall out of the inside of the clamping tube 2 (at this time, the clamping tube 2 is in a perpendicular state to the pile body), which makes it easier for the subsequent pile body to enter the inside of the clamping tube 2.

[0040] Specifically, when the clamping tube 2 is flush with the pile body (the clamping tube 2 and the pile body are tilted on the ground at the same time), the movable plug 402 on the guide block 301 is reset under the action of the return spring 403, which drives the movable plug 402 to move down. When the movable plug 402 moves down, it will generate negative pressure, which will cause the hydraulic oil inside the fixed cylinder 5 to flow back into the oil chamber 4. At the same time, it will drive the moving rod 501 to move up, which will drive the crushing block 503 inside the arc groove 504 to move up, and perform secondary crushing of the soil, which can better clean the soil inside the clamping tube 2.

[0041] Preferably, the cross-section of the crushing block 503 is triangular, and the crushing block 503 is fitted to the curved surface of the arc groove 504.

[0042] Specifically, the arc-shaped groove 504, compared to the vertically arranged groove, can increase the moving distance of the crushed block 503, thereby enabling more soil to be crushed. The curved surface of the crushed block 503 fits into the arc-shaped groove 504, and the crushed block 503 is hinged to the connecting rod 502. This connection method ensures that when the crushed block 503 changes its moving direction inside the arc-shaped groove 504, there will be no motion interference, and the crushed end of the crushed block 503 can always be aligned with the soil, reducing the moving resistance of the crushed block 503.

[0043] like Figure 8As shown, a clamping structure, including a clamping block 408, is provided on the outer side of the clamping tube 2. The clamping structure can assist in clamping the pile inside the clamping tube 2. The clamping structure of the clamping tube 2 uses hydraulic pressure as a power source to drive the clamping block 408 to move inside the clamping tube 2. This allows the clamping block 408 to clamp the pile inside the clamping tube 2, preventing the pile from falling out of the clamping tube 2 during hoisting. The clamping structure also includes a clamping cylinder 409, which is mounted on the pile frame 1. The output end of the clamping cylinder 409 is fixedly connected to the clamping block 408. Auxiliary clamping blocks 407 are fixedly connected to both sides of the clamping block 408. Multiple clamping holes and slots are provided through the surface of the clamping tube 2. The auxiliary clamping blocks 407 and the clamping blocks 408 are mating components with the clamping holes and slots. Multiple limiting blocks 6 are fixedly connected inside the clamping tube 2. The limiting blocks 6 are located below the connecting rod 502.

[0044] When the pile enters the clamping tube 2, the clamping cylinder 409 is activated, causing the clamping block 408 to deflect at an angle to clamp the pile inside the clamping tube 2 and prevent it from falling out. This is existing technology and will not be described in detail. What needs to be specifically explained is that auxiliary clamping blocks 407 are also provided on both sides of the clamping block 408. When the clamping block 408 deflects at an angle, the auxiliary clamping blocks 407 can also enter the interior of the clamping tube 2 through the corresponding slots and fit against the pile. This setting can increase the friction between the pile and the clamping block 408 and prevent the pile from falling out of the clamping tube 2.

[0045] In addition, the limiting block 6 sets a limiting effect on the pile inside the clamping tube 2, preventing the pile from hitting the breaking block 503 when it is inside the clamping tube 2. The arc groove 504 does not contact the limiting block 6, thus preventing the breaking block 503 from contacting the limiting block 6 when it moves. The side of the clamping tube 2 with the clamping block 408 is not provided with the arc groove 504 and the breaking block 503, because when the clamping block 408 deflects at an angle, it can clear some of the solidified soil. Therefore, there is no need to provide the arc groove 504, and it can prevent the breaking block 503 from interfering with the movement between the clamping block 408.

[0046] Working Principle: When pile lifting is required, the crane moves the clamping tube 2 downwards. The clamping tube 2 must contact the edge of the pile body during this downward movement. Then, the guide block 301 is placed against the edge of the pile body. When the guide block 301 is in contact with the clamping tube 2, under the weight of the clamping tube 2 itself, the guide block 301 will move upwards, moving inside the clamping tube 2 via the sliding rod 303. This shortens the overall length of the clamping tube 2 and the guide block 301. This design allows operators to quickly determine the correct placement of the clamping tube 2 along the edge of the pile body. However, because the lengths of the fixed guide blocks 301 vary, operators need to observe and adapt over a long period to determine their correct placement, increasing the difficulty of operation. When the vibrating motor and the crane move, the front end of the pile body enters the clamping tube 2. If the pile body and the clamping tube 2 are not fully aligned at this time... Driven by the vibratory motor and the crane, the clamping tube 2 and the pile body are aligned. Then, the crane is moved again and the vibratory motor is started, so that the pile body is fully inserted into the clamping tube 2. When the guide block 301 moves upward, the movable plug 402 moves inside the oil chamber 4 through the transmission rod 401. When the movable plug 402 moves upward, it pushes the hydraulic oil in the oil chamber 4 upward. The hydraulic oil enters the fixed cylinder 5 through the oil guide pipe 405. The hydraulic oil in the fixed cylinder 5 pushes the moving rod 501 downward. The moving rod 501 drives the crushing block 503 to move along the arc groove 504. The crushing block 503 moves downward in an arc along the arc groove 504, crushing the large volume of soil adhering inside the clamping tube 2. The soil then falls out of the clamping tube 2, making it easier for the subsequent pile body to enter the clamping tube 2. During this process, the clamped pile is embedded into the designated position under the action of the vibratory pile driver. After the previous photovoltaic support pile is embedded, the crane re-controls the vibratory pile driver and its pile clamp (i.e., the clamping pipe 2 in this application) to clamp another new pile for a new pre-embedding (pile driving) operation. This process is repeated in sequence to achieve the purpose of driving piles for the photovoltaic support system.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
