Description

Technical Field

[0001] This invention relates to the field of basic connection structure technology, and more specifically, to a construction structure and construction equipment for photovoltaic module installation. Background Technology

[0002] In traditional photovoltaic (PV) module installation processes, foundation construction is required first, including on-site positioning, piling, or concrete foundation pouring. Only after the foundation reaches the designed strength can the PV brackets be installed and leveled, and finally the PV modules are laid and fixed. Among these steps, concrete foundation pouring is a key step in PV module installation. It involves pouring concrete at precise locations to form concrete piers. Once the foundation is stable, the metal brackets are fixed to the concrete piers. The concrete piers provide a sturdy, level, and durable support platform for the entire PV system.

[0003] When pouring concrete foundations, J-bolts with threads at one end are typically pre-embedded in the concrete. After the concrete hardens, the base of the support bracket fits onto the anchor bolts through pre-drilled holes and is then tightened with nuts and washers. While this traditional method of pre-embedded anchor bolt fixing is low-cost and versatile, the bolts are easily displaced by the impact of the concrete during pouring, leading to deviations in position, elevation, and verticality. This makes subsequent installation difficult, and once the concrete hardens, the bolt position cannot be adjusted, necessitating rework if deviations occur. Therefore, we propose a construction structure and equipment for photovoltaic module installation. Summary of the Invention

[0004] The purpose of this invention is to provide a construction structure and equipment for installing photovoltaic modules, so as to solve the technical problem that once the concrete solidifies, the bolt position cannot be adjusted and rework is necessary when deviations occur.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a construction structure for photovoltaic module installation, comprising a concrete pier, the concrete pier being formed by pouring concrete into a foundation pit, a base adjustment assembly being arranged on the top of the concrete pier, and a metal bracket being connected to the top of the base adjustment assembly, the metal bracket being used to support the photovoltaic panels; multiple J-type anchor bolts are embedded inside the concrete pier, the threaded portion of the top of the J-type anchor bolts extending above the concrete pier; the base adjustment assembly is connected to the top of the concrete pier via the J-type anchor bolts; the base adjustment assembly includes a base plate, a pressure plate being arranged above the base plate, a gasket being arranged between the base plate and the pressure plate, an adjustment cylinder seat being arranged in the inner cavity of the pressure plate, the adjustment cylinder seat being connected to the metal bracket via bolts and nuts; the adjustment cylinder seat can be in a movable or fixed state in the horizontal direction; in the movable state, the adjustment cylinder seat can move to a preset position at the bottom connection of the metal bracket and connect with the metal bracket; after connection, the adjustment cylinder seat can be in a fixed state, so that the metal bracket is stably fixed.

[0006] Preferably, the base plate and the pressure plate are fixed to the screw of the J-type anchor bolt by a nut. By adjusting the nut on the screw of the J-type anchor bolt, the base plate and the pressure plate can be in a relaxed or tightened state. An adjustment groove is provided on the top of the base plate; the adjustment groove is a circular groove structure. An adjustment sleeve hole is provided on the pressure plate from top to bottom, and a pressure ring is connected to the bottom of the pressure plate, the pressure ring being arranged within the adjustment groove. The adjustment cylinder seat consists of a cylinder rod and a circular plate; the circular plate is connected to the bottom of the cylinder rod, and the cylinder rod is movable. The circular plate is movably arranged in the adjustment groove and the pressure ring is arranged on the top of the circular plate. When the base plate and the pressure plate are in a relaxed state, the position of the cylinder rod in the horizontal direction can be changed by adjusting the position of the circular plate in the adjustment groove until the connection between the cylinder rod and the metal bracket is aligned. Then, by adjusting the base plate and the pressure plate to a tight state, the pressure ring is pressed down on the top of the circular plate to form a clamping and fixing state for the circular plate, so that the adjustment cylinder seat can be fixed.

[0007] Preferably, a sealing cover is threaded onto the outer circumference of the cylinder rod, and the sealing cover is arranged on the top of the pressure plate; a reinforcing rib is also connected to the outer circumference of the cylinder rod.

[0008] Preferably, the outer circumference of the circular plate is provided with an annular groove; the four side walls of the substrate are respectively provided with fixing cylinders of the same structure, and the inner cavity of the fixing cylinder is movably provided with an internal hexagon bolt, the thread of the internal hexagon bolt passes through the side wall of the substrate and extends into the adjustment groove; the screw head of the internal hexagon bolt can be inserted into the annular groove.

[0009] A construction device for installing photovoltaic modules, applicable to the aforementioned construction structure, includes a base frame. Two slidable support frames are arranged symmetrically within the base frame's inner cavity. Two rotating landing gears are rotatably arranged on the inner sidewall of the base frame, also symmetrically arranged. Each support frame has a support groove and multiple semi-support grooves at its top, the support groove supporting the fixing cylinder of the substrate sidewall. An overflow groove is provided on the sidewall of the support frame to control the upper limit of cement pouring within the support frame's inner cavity. The two support frames have a combined state and a separated state. In the combined state, the two support frames... The semi-support slots of the shaped support frame can be merged to form the support slot structure. The inner cavity formed by the two shaped support frames in the merged state is used to position and support the base adjustment assembly. In the separated state, the two shaped support frames can be separated from the cast concrete pier. The rotating landing gear has casters at the top of the pole, a fixing plate on the side wall of the rotating landing gear, and a pressure block slidably arranged on the side wall of the fixing plate. The two rotating landing gears can rotate synchronously in opposite directions. When the two rotating landing gears rotate synchronously upward, the shaped support frame can be lowered to the ground surface. When the two rotating landing gears rotate synchronously downward, the shaped support frame can be lifted upward from the ground surface.

[0010] Preferably, the inner sidewall of the equipment base frame is connected to multiple guide rods, the top of the equipment base frame is arranged with a machine compartment, the machine compartment is equipped with a first motor, and the output end of the first motor is connected to a transmission gear; the sidewall of the shaping support frame is provided with multiple sliding holes, the guide rods are arranged in the sliding holes, and the shaping support frame slides with the guide rods through the sliding holes; one sidewall of the shaping support frame is connected to an upper toothed plate, and the sidewall of the upper toothed plate slides with the sidewall of the other shaping support frame; the sidewall of the other shaping support frame is connected to a lower toothed plate, and the transmission gear is arranged between the lower toothed plate and the upper toothed plate, and the lower toothed plate and the upper toothed plate are respectively meshed with the transmission gear.

[0011] Preferably, the equipment base frame sidewall is rotatably arranged with a plurality of small gears, a plurality of small gears, a plurality of medium gears, and a plurality of large gears. Two small gears are meshed with each other, small gears are meshed with small gears, small gears are meshed with small gears, small gears are meshed with medium gears, and medium gears are meshed with large gears. A second motor is installed on the other sidewall of the equipment base frame, and the output end of the second motor is coaxially connected to one of the small gears. The rotating shaft of the rotating landing gear is coaxially connected to the large gear.

[0012] Preferably, a third motor is installed on the side wall of the fixed plate, a gear three is connected to the output end of the third motor, a gear four is meshed with the output end of the gear three, a lead screw is coaxially connected to the gear four, the lead screw is rotatably arranged on the side wall of the fixed plate, and multiple sliding grooves are provided on the side wall of the fixed plate.

[0013] Preferably, the pressure block includes multiple L-shaped plates, with a pressure cover connected to the top of each L-shaped plate. Multiple sliding plates are connected to the sidewalls of the pressure cover, and the sliding plates are slidably arranged within the groove. A driving block is connected to the top of the pressure cover, and a lead screw is movably arranged within the inner cavity of the driving block and threadedly engaged with it. The L-shaped plates can be pressed into the inner cavity of the shaping support frame and are located to the side of the overflow groove opening, thus closing the overflow groove opening. At this time, the pressure cover can press down on the top of the pressure plate of the base adjustment assembly, positioning the base adjustment assembly. When the two rotating landing gears rotate synchronously upwards to a vertical position, the two pressure blocks form a symmetrical structure, causing the multiple pressure covers to be arranged at the four corners for pressing and positioning the top four corners of the pressure plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by designing a base adjustment assembly on the top of the concrete pier, allows the adjustment cylinder seat to move freely or be firmly clamped in the horizontal direction by adjusting the tightness of the nuts on the J-type anchor bolts. This achieves a precise connection of the metal bracket. Even if there is a slight deviation in the J-type anchor bolts during the pouring process, the position of the adjustment cylinder seat of the base adjustment assembly on the horizontal plane can be adjusted to precisely align it with the metal bracket. This greatly improves installation efficiency and success rate. Installers do not need to rework on-site due to incorrect hole positions; they only need to make minor adjustments to complete the connection. This reduces construction difficulty and solves the problem in traditional processes where the bracket cannot be aligned if the pre-embedded anchor bolts are not in the correct position.

[0015] 2. This invention achieves a dual fixing effect on the adjusting cylinder seat by opening an annular groove on the outer circumference of the circular plate of the adjusting cylinder seat and arranging fixing cylinders and internal hexagon bolts on the four side walls of the base plate. After the circular plate of the adjusting cylinder seat moves to the target position in the adjusting groove, the nuts on the J-type anchor bolts are tightened to press down the pressure plate and lock the adjusting cylinder seat in the target position. Then, the internal hexagon bolts around the base plate are tightened so that their screw heads are inserted into the annular groove of the circular plate to form a radial mechanical limit. Combined with the axial clamping force of the pressure plate, this effectively prevents the adjusting cylinder seat from rotating or displacing horizontally when under force, significantly improving the connection stability and vibration resistance, providing more reliable support for the metal bracket, and solving the problem that the circular plate may slide laterally due to friction after being pressed and fixed by the pressure plate in the adjusting groove.

[0016] 3. This invention designs an auxiliary construction device for photovoltaic module installation. Before pouring the foundation pit, this device supports the base adjustment assembly using two combined fixed support frames. The base adjustment assembly, connected to multiple J-type anchor bolts via nuts, is supported, allowing the fixing cylinders on the four sides of the base plate to be placed in the support grooves of the fixed support frames, thus supporting and positioning the base adjustment assembly. Subsequently, the pushing device moves the base adjustment assembly above the foundation pit, and then two rotating lifting frames rotate synchronously upwards, causing the fixed support frames to descend towards the foundation surface until they land at the pit opening. At this point, the J-shaped rods of the multiple J-type anchor bolts are located within the pit, providing support for the base adjustment assembly. The positioning above the foundation pit is then completed by pouring concrete into the pit through the foundation pouring channel between the fixed support frame and the base adjustment assembly until the concrete level reaches the overflow tank. This process changes the traditional method of embedding J-type anchor bolts into the concrete pier. By treating the base adjustment assembly and the J-type anchor bolts as a whole, precise positioning is achieved before pouring, avoiding the problem of J-type anchor bolts shifting due to concrete impact in the traditional process. This ensures the accuracy of the final position of the J-type anchor bolts. Because the J-type anchor bolts are precisely positioned, there is no need for tedious position adjustments when installing the metal brackets. Even if there is a positional deviation, the position can be calibrated in time through the function of the base adjustment assembly, greatly improving installation efficiency.

[0017] 4. This invention features two rotating landing gears. These can simultaneously rotate downwards to a vertical position, utilizing casters to achieve flexible movement and precise positioning of the entire equipment. Simultaneously, they can rotate to a horizontal position, ensuring stable contact between the support frame and the foundation pit, and unobstructed flow in the concrete foundation pouring channel. Furthermore, they can simultaneously rotate upwards to a vertical position, facilitating the positioning constraint of the base adjustment assembly and the sealing control of the overflow groove by the pressure block. No additional equipment is needed for movement or positioning; equipment relocation, foundation pit contact, and pouring protection can be completed simply by switching the states of the rotating landing gears, simplifying the construction process.

[0018] 5. This invention, through the design of a pressure block, stops pouring when the poured concrete overflows from the overflow trough. Subsequently, by pressing down with the pressure block, an L-shaped plate is pressed into the inner cavity of the shaping support frame from the foundation pouring channel inlet, flattening the top of the concrete liquid and sealing the overflow trough. This causes the concrete liquid to form a concrete pier shape within the inner cavity of the shaping support frame and the foundation pit. Specifically, the lower half of the concrete pier is embedded in the foundation, while the upper half is located within the inner cavity of the shaping support frame and shaped by the L-shaped plate. Simultaneously, the pressure cover precisely presses down on the top of the pressure plate of the base adjustment assembly, achieving stable positioning of the base adjustment assembly. This ensures the stability of the concrete liquid forming and the position of the base adjustment assembly, solving the problem that the concrete liquid, under the pressure of the L-shaped plate, pushes the base adjustment assembly upwards, causing a change in the position of the base adjustment assembly.

Detailed Implementation

[0021] Example 1, as Figures 1 to 6As shown, this embodiment provides a construction structure for photovoltaic module installation, including a concrete pier 1, which is formed by pouring concrete into a foundation pit 2. A base adjustment assembly 3 is arranged on the top of the concrete pier 1, and a metal bracket 4 is connected to the top of the base adjustment assembly 3. The metal bracket 4 supports the photovoltaic panels. Multiple J-type anchor bolts 101 are embedded inside the concrete pier 1, with the threaded portion of the J-type anchor bolts 101 extending above the concrete pier 1. The exposed threaded portion is used for installing and fixing the upper structure. The base adjustment assembly 3 is connected to the top of the concrete pier 1 via the J-type anchor bolts 101. The seat adjustment assembly 3 includes a base plate 301, a pressure plate 302 arranged above the base plate 301, a gasket 303 made of rubber arranged between the base plate 301 and the pressure plate 302, and an adjustment cylinder seat 304 arranged in the inner cavity of the pressure plate 302. The adjustment cylinder seat 304 is connected to the metal bracket 4 by bolts and nuts. The adjustment cylinder seat 304 can be in a movable state or a fixed state in the horizontal direction. In the movable state, the adjustment cylinder seat 304 can move to a preset position at the bottom connection of the metal bracket 4 and connect with the metal bracket 4. After connection, the adjustment cylinder seat 304 can be in a fixed state to stably fix the metal bracket 4.

[0022] In an embodiment of the present invention, the substrate 301 and the pressure plate 302 are fixed to the screw of the J-type anchor bolt 101 by a nut. By adjusting the nut on the screw of the J-type anchor bolt 101, the substrate 301 and the pressure plate 302 can be in a relaxed state or a tight state. An adjustment groove 3011 is provided on the top of the substrate 301, and the adjustment groove 3011 is a circular groove structure. An adjustment sleeve hole 3021 is provided from top to bottom on the pressure plate 302, and a pressure ring 3022 is connected to the bottom of the pressure plate 302. The pressure ring 3022 is arranged in the adjustment groove 3011. The adjustment cylinder seat 304 is composed of a cylinder rod 3041 and a circular plate 3042, and the circular plate 3042 is connected to the bottom of the cylinder rod 3041. The cylinder rod 3041 is movably arranged in the adjusting sleeve hole 3021, the circular plate 3042 is movably arranged in the adjusting groove 3011, and the pressure ring 3022 is arranged on the top of the circular plate 3042. When the base plate 301 and the pressure plate 302 are in a relaxed state, the position of the cylinder rod 3041 in the horizontal direction can be changed by adjusting the position of the circular plate 3042 in the adjusting groove 3011 until the connection between the cylinder rod 3041 and the metal bracket 4 is aligned. Then, by adjusting the base plate 301 and the pressure plate 302 to be in a tight state, the pressure ring 3022 is pressed down on the top of the circular plate 3042 to form a clamping and fixing state for the circular plate 3042, so that the adjusting cylinder seat 304 can be fixed.

[0023] The pressure between the base plate 301 and the pressure plate 302 is controlled by tightening or loosening the nuts on the J-type anchor bolts 101. Loosening the nuts allows the base plate 301 and the pressure plate 302 to relax. At this time, the pressure ring 3022 at the bottom of the pressure plate 302 no longer presses against the circular plate 3042 of the adjusting cylinder seat 304. The circular plate 3042 can then slide freely in the circular adjusting groove 3011 of the base plate, thereby driving the upper cylinder rod 3041 to move horizontally until it is precisely aligned with the metal bracket 4. After alignment, tightening the nuts causes the pressure plate 302 to press down. The pressure ring 3022 at the bottom of the pressure plate 302 then tightly clamps the circular plate 3042 in the adjusting groove 3011 of the base plate 301, thereby locking the adjusting cylinder seat 304 in a precise position and completing the stable connection with the metal bracket 4. This invention, by designing a base adjustment assembly 3 on the top of the concrete pier 1, allows the adjustment cylinder seat 304 to move freely or be firmly clamped in the horizontal direction by adjusting the tightness of the nuts on the J-type anchor bolts 101. This achieves the effect of precisely connecting the metal bracket 4. Even if there is a slight deviation in the J-type anchor bolts 101 during the pouring process, the position of the adjustment cylinder seat 304 on the horizontal plane can be adjusted by adjusting the base adjustment assembly 3 to precisely align it with the metal bracket 4. This greatly improves the installation efficiency and success rate. Installers do not need to rework on-site due to incorrect hole positions; they only need to make minor adjustments to complete the connection. This reduces the construction difficulty and solves the problem in traditional processes where the bracket cannot be aligned if the pre-embedded anchor bolts are not in the correct position.

[0024] In another embodiment of the present invention, a sealing cover 3043 is threadedly connected to the outer circumference of the cylinder rod 3041. The sealing cover 3043 is arranged on the top of the pressure plate 302 and can prevent external impurities from entering the adjusting groove 3011. A reinforcing rib 3044 is also connected to the outer circumference of the cylinder rod 3041. The reinforcing rib 3044 is used to improve the strength of the cylinder rod 3041.

[0025] In another embodiment of the present invention, an annular groove 3045 is provided on the outer circumference of the circular plate 3042; a fixing cylinder 3012 with the same structure is arranged on the four side walls of the base plate 301, and an internal hexagon bolt 3013 is movably arranged in the inner cavity of the fixing cylinder 3012. The thread of the internal hexagon bolt 3013 passes through the side wall of the base plate 301 and extends into the adjusting groove 3011; the screw head of the internal hexagon bolt 3013 can be inserted into the annular groove 3045. By creating an annular groove 3045 on the outer circumference of the circular plate 3042 of the adjusting cylinder seat 304, and arranging fixing cylinders 3012 and hexagonal socket head cap screws 3013 on the four side walls of the base plate 301, a dual fixing effect is achieved for the adjusting cylinder seat 304. After the circular plate 3042 of the adjusting cylinder seat 304 moves to the target position in the adjusting groove 3011, the pressure plate 302 is pressed down by tightening the nut on the J-type anchor bolt 101, locking the adjusting cylinder seat 304 in the target position. Then, the base plate is tightened... The hexagonal socket head cap screws 3013 around the plate 301 allow their screw heads to be inserted into the annular groove 3045 of the circular plate, forming a radial mechanical limit. Combined with the axial clamping force of the pressure plate 302, this effectively prevents the adjusting cylinder seat from rotating or displacing horizontally when under force, significantly improving connection stability and vibration resistance. This provides more reliable support for the metal bracket 4 and solves the problem that the circular plate 3042 may slide laterally after being pressed and fixed by the pressure plate 302 in the adjusting groove 3011 to overcome friction.

[0026] Example 2, as Figures 7 to 17As shown, this embodiment provides a construction device for photovoltaic module installation, applicable to the aforementioned construction structure. It includes a base frame 5, with two slidably arranged support frames 6 within the base frame 5, arranged symmetrically. Two rotating landing gears 7 are rotatably arranged on the inner sidewall of the base frame 5, also arranged symmetrically. Each support frame 6 has a support groove 601 and multiple semi-support grooves 602 at its top. The support groove 601 supports the fixing cylinder 3012 on the sidewall of the substrate 301. An overflow groove 603 is provided on the sidewall of the support frame 6 to control the upper limit of cement pouring within the cavity of the support frame 6. The two support frames 6 have a combined state and a separated state. In the combined state, the semi-support grooves 602 of the two support frames 6 can merge to form the support groove 601 structure. The inner cavity formed by the two fixed support frames 6 is used to position and support the base adjustment assembly 3, and the inner cavity of the fixed support frame 6 can form the shape of the concrete pier 1. The gap between the inner cavity of the fixed support frame 6 and the base adjustment assembly 3 forms the foundation pouring channel 8, which is used for concrete pouring to form the shape of the concrete pier 1. In the separated state, the two fixed support frames 6 can separate from the poured concrete pier 1. The pole head of the rotating landing gear 7 is equipped with casters 71, and the side wall of the rotating landing gear 7 is equipped with a fixing plate 72. The side wall of the fixing plate 72 is slidably equipped with a pressure block 73. The two rotating landing gears 7 can rotate synchronously in opposite directions. When the two rotating landing gears 7 rotate synchronously upward, the fixed support frame 6 can be lowered to the surface of the foundation 2. When the two rotating landing gears 7 rotate synchronously downward, the fixed support frame 6 can be lifted off the surface of the foundation 2.

[0027] This invention designs an auxiliary construction device for photovoltaic module installation. This device supports the base adjustment assembly 3 using two combined, fixed support frames 6 before pouring the foundation pit 2. Figure 15 As shown, the base adjustment assembly 3, which is connected to multiple J-type anchor bolts 101 by nuts, is supported. The fixing cylinders 3012 on the four sides of the base plate 301 of the base adjustment assembly 3 are placed in the support grooves 601 of the shaping support frame 6, thus supporting and positioning the base adjustment assembly 3. Then, the equipment is pushed, and the universal wheels 71 of the rotating landing gear 7 are used to move the base adjustment assembly 3 above the foundation pit of the foundation 2. Then, the two rotating landing gears 7 rotate upwards synchronously, causing the shaping support frame 6 to descend towards the surface of the foundation 2 until it lands at the opening of the foundation pit. At this point, the J-shaped rods of the multiple J-type anchor bolts 101 are located inside the foundation pit. Figure 16As shown, the base adjustment assembly 3 is positioned above the foundation pit. Finally, concrete is poured into the foundation pit through the foundation pouring channel 8 between the inner cavity of the shaping support frame 6 and the base adjustment assembly 3 until the concrete level reaches the overflow groove 603, completing the pouring. In this process, the traditional pouring method of embedding the J-type anchor bolt 101 into the concrete pier 1 is changed. The base adjustment assembly 3 and the J-type anchor bolt 101 are treated as a whole, and precise positioning is achieved before pouring. This avoids the problem of the J-type anchor bolt 101 shifting due to concrete impact in the traditional process, ensuring the accuracy of the final position of the J-type anchor bolt 101. Because the position of the J-type anchor bolt 101 is accurate, there is no need to make tedious position adjustments when installing the metal bracket 4. Even if there is a position deviation, the position can be calibrated in time through the function of the base adjustment assembly 3, which greatly improves the installation efficiency.

[0028] In an embodiment of the present invention, a plurality of guide rods 501 are connected to the inner sidewall of the equipment base frame 5, and a machine compartment 502 is arranged on the top of the equipment base frame 5. A first motor 503 is installed in the machine compartment 502, and a transmission gear 504 is connected to the output end of the first motor 503. A plurality of sliding holes 604 are opened on the sidewall of the shaping support frame 6, and the guide rods 501 are arranged in the sliding holes 604. The shaping support frame 6 slides with the guide rods 501 through the sliding holes 604. An upper toothed plate 605 is connected to the sidewall of one shaping support frame 6, and the sidewall of the upper toothed plate 605 slides with the sidewall of another shaping support frame 6. A lower toothed plate 606 is connected to the sidewall of the other shaping support frame 6, and the transmission gear 504 is arranged between the lower toothed plate 606 and the upper toothed plate 605. The lower toothed plate 606 and the upper toothed plate 605 are respectively meshed with the transmission gear 504.

[0029] In another embodiment of the present invention, a plurality of pinion gears 505, a plurality of pinion gears 506, a plurality of intermediate gears 507 and a plurality of large gears 508 are rotatably arranged on the side wall of the equipment base frame 5. Two pinion gears 505 are meshed with each other, pinion gear 505 is meshed with pinion gear 506, pinion gear 506 is meshed with intermediate gear 507, and intermediate gear 507 is meshed with large gear 508. A second motor 509 is installed on the other side wall of the equipment base frame 5. The output end of the second motor 509 is coaxially connected to one of the pinion gears 505. The rotating shaft of the rotating landing gear 7 is coaxially connected to the large gear 508.

[0030] The second motor 509 drives the gear transmission system to achieve smooth lifting and lowering of the shaping support frame 6. The motor power is transmitted sequentially through pinion 505, pinion 506, intermediate gear 507, and large gear 508, with gear reduction and torque increase ensuring synchronization on both sides. Finally, the large gear 508 drives the rotary landing gear 7 to rotate around its axis. When the two rotary landing gears 7 rotate upward synchronously, their bottom casters 71 swing outward, the support points move outward, and the equipment base frame 5 and the shaping support frame 6 smoothly descend to the surface of the foundation 2 under the action of gravity; conversely, they are lifted upward.

[0031] This invention designs two rotating landing gears 7. When the two rotating landing gears 7 rotate downwards synchronously to a vertical position, they are used to lift the equipment base frame 5 and the fixed support frame 6 as a whole off the surface of the foundation 2. At this time, the universal wheels 71 at the top of the rotating landing gear 7 stably contact the ground, forming a support foundation for equipment movement. This facilitates construction personnel to push the equipment and precisely move the fixed support frame 6, which is pre-loaded with the base adjustment assembly 3 assembled with J-type anchor bolts 101 using nuts, to the top of the foundation pit of the foundation 2. This lays the foundation for the positioning work before subsequent concrete pouring. When the two rotary landing gears 7 rotate synchronously to a horizontal position, the fixed support frame 6 not only presses down on the foundation pit of the foundation 2, causing the base adjustment assembly 3 to fall on the foundation pit of the foundation 2, but also allows observation of whether the base adjustment assembly 3 is aligned with the center of the foundation pit. Simultaneously, during pouring, the rotary landing gear 7 does not obstruct the entrance to the foundation pouring channel 8 between the fixed support frame 6 and the base adjustment assembly 3, facilitating concrete pouring into the foundation pit through this channel. When the two rotary landing gears 7 rotate synchronously upward to a vertical position, the pressure block 73 remains... Above the foundation pouring channel 8, multiple pressure covers 7302 are precisely pressed down at four corners onto the top of the pressure plate 302 of the base adjustment assembly 3, forming a stable positioning constraint on the base adjustment assembly 3 and preventing the base adjustment assembly 3 from shifting due to concrete impact during pouring. At the same time, the L-shaped plate 7301 will simultaneously press into the inner cavity of the shaping support frame 6 and close the overflow groove 603, ensuring that the concrete pouring height does not exceed the design limit and guaranteeing the forming quality of the concrete pier 1. This enables the rotating landing gear 7 to have a multi-state adaptive function, which can be achieved by synchronously rotating downwards. When rotated to a vertical position, the equipment can be moved flexibly and positioned precisely by relying on the casters 71; it can also be rotated to a horizontal position to ensure the stable fit between the fixed support frame 6 and the foundation pit and the smooth flow of the concrete foundation pouring channel; it can also be rotated upwards to a vertical position to facilitate the positioning constraint of the base adjustment assembly 3 by the pressure block 73 and the sealing control of the overflow groove 603; without the need for additional equipment to assist in movement or positioning, the equipment relocation, foundation pit fit, and pouring protection can be completed by rotating the landing gear 7, simplifying the construction steps.

[0032] In another embodiment of the present invention, a third motor 7201 is installed on the side wall of the fixed plate 72. The output end of the third motor 7201 is connected to a gear 7202. The output end of the gear 7202 is meshed with a gear 7203. The gear 7203 is coaxially connected to a lead screw 7204. The lead screw 7204 is rotatably arranged on the side wall of the fixed plate 72. The side wall of the fixed plate 72 is provided with a plurality of sliding grooves 7205.

[0033] Furthermore, the pressure block 73 includes multiple L-shaped plates 7301, with a pressure cover 7302 connected to the top of the L-shaped plates 7301. Multiple sliding plates 7303 are connected to the side wall of the pressure cover 7302. The sliding plates 7303 are slidably arranged in the sliding groove 7205. A driving block 7304 is connected to the top of the pressure cover 7302. The lead screw 7204 is movably arranged in the inner cavity of the driving block 7304 and is threadedly engaged with the inner cavity of the driving block 7304. The L-shaped plates 7301 can be pressed into the inner cavity of the shaping support frame 6 and are located on the side of the opening of the overflow groove 603, so that the opening of the overflow groove 603 is closed. At this time, the pressure cover 7302 can press down on the top of the pressure plate 302 of the base adjustment assembly 3 to position the base adjustment assembly 3. When the two rotating landing gears 7 rotate upwards to a vertical position in sync, the two pressure blocks 73 form a symmetrical structure, so that multiple pressure covers 7302 are arranged in a four-corner orientation, which is used to press down and position the top four corners of the pressure plate 302.

[0034] The third motor 7201 drives gears 7202 and 7203, transmitting power to the lead screw 7204 to rotate. The rotation of the lead screw 7204, through its threaded engagement with the drive block 7304, converts the rotational motion into linear motion, thereby driving the entire pressure block 73 to descend smoothly along the slide groove 7205 on the fixed plate 72. During the descent, the L-shaped plate 7301 first presses into the inner cavity of the shaping support frame 6, sealing its overflow groove 603 and controlling the concrete pouring height; simultaneously, the pressure cover 7302 precisely presses down on the top of the pressure plate 302 of the base adjustment assembly 3, achieving stable positioning of the base adjustment assembly 3.

[0035] This invention designs a pressure block 73 that stops pouring when the concrete overflows from the overflow trough 603. Subsequently, the pressure block 73 presses down, and the L-shaped plate 7301 is pressed into the inner cavity of the shaping support frame 6 from the inlet of the foundation pouring channel 8, flattening the top of the concrete liquid and sealing the overflow trough 603. This causes the concrete liquid to form a concrete pier 1 shape in the inner cavity of the shaping support frame 6 and the foundation pit of the foundation 2. That is, the lower half of the concrete pier 1 is embedded in the foundation 2, and the upper half is located in the inner cavity of the shaping support frame 6 and is shaped by the L-shaped plate 7301. At the same time, the pressure cover 7302 presses precisely down on the top of the pressure plate 302 of the base adjustment assembly 3, achieving stable positioning of the base adjustment assembly 3. This ensures the stability of the concrete liquid forming and the position of the base adjustment assembly 3, solving the problem that the concrete liquid is pushed upward by the pressure of the L-shaped plate 7301, causing the position of the base adjustment assembly 3 to change.

[0036] Example 3: This example provides a method for using construction equipment for photovoltaic module installation, including the following steps: S1. Pre-assembly of the base adjustment assembly: The screw portions of multiple J-type anchor bolts 101 are passed through the preset holes in the base plate 301 of the base adjustment assembly 3, ensuring that the J-type rods of the J-type anchor bolts 101 face downwards; then the circular plate 3042 of the adjustment cylinder seat 304 is placed in the adjustment groove 3011 of the base plate 301, and the gasket 303 and pressure plate 302 are sequentially inserted through the cylinder rod 3041. The screws of the J-type anchor bolts 101 are screwed into the top of the pressure plate 302 by the nut to form a preliminary fixation. Finally, the sealing cover 3043 is tightened on the top of the cylinder rod 3041 to complete the preliminary assembly of the base adjustment assembly 3. S2, Base adjustment assembly support operation: The initially assembled base adjustment assembly 3 is hoisted above the combined shaping support frame 6, so that the fixing cylinders 3012 on the four sides of the base plate 301 are accurately embedded in the support grooves 601 of the shaping support frame 6, thereby achieving the positioning and support of the base adjustment assembly 3 on the equipment. S3. Pit alignment operation: Push the equipment and move it to the top of the pit of foundation 2 using casters 71; start the second motor 509 to control the two rotating landing gears 7 to rotate upward synchronously until the rotating landing gears 7 are horizontal. At this time, the fixed support frame 6 descends smoothly under the action of gravity and finally fits against the edge of the pit opening; check and confirm that the J-shaped rod of the J-shaped anchor bolt 101 is fully inserted into the pit and the base adjustment assembly 3 is directly above the pit, completing the alignment. S4. Concrete pouring operation: Concrete is slowly poured into the foundation pit of the foundation 2 through the foundation pouring channel 8 between the inner cavity of the fixed support frame 6 and the base adjustment assembly 3. During the pouring process, the overflow trough 603 is observed. When the concrete liquid level rises to the overflow trough 603 and overflows slightly, the pouring is stopped. At this time, the amount of concrete has met the design height of the concrete pier 1. S5. Pressing down and positioning operation of the pressure block: Start the third motor 7201 on the side wall fixing plate 72 of the rotating landing gear 7. The third motor 7201 drives the gear three 7202 to rotate. The gear three 7202 drives the meshing gear four 7203 and the coaxial lead screw 7204 to rotate. The lead screw 7204 pushes the pressure block 73 to descend vertically along the slide groove 7205 through the threaded engagement with the drive block 7304. The L-shaped plate 7301 of the pressure block 73 first presses into the inner cavity of the shaping support frame 6, fits the concrete liquid surface and seals the overflow groove 603 to prevent concrete from overflowing and flatten the top of the concrete. At the same time, the pressure cover 7302 of the pressure block 73 presses down precisely at the four corners of the top of the pressure plate 302 of the base adjustment assembly 3, forming a stable constraint on the base adjustment assembly 3 and preventing the base adjustment assembly 3 from shifting during the concrete solidification process. S6. After the concrete solidifies, the pressure block is reset. Wait for the concrete in the pit to completely solidify and form the concrete pier 1. Then start the third motor 7201 to rotate in the opposite direction, drive the pressure block 73 to rise and reset along the slide 7205, and disengage from the inner cavity of the fixed support frame 6 and the base adjustment assembly 3. S7. Separation of the shaping support frame and lifting of the equipment: Start the first motor 503 to drive the transmission gear 504 to rotate in the opposite direction, causing the two shaping support frames 6 to slide synchronously in the opposite direction along the guide rod 501 and enter the separation state, separating from the outer wall of the concrete pier 1; then start the second motor 509 to control the rotating lifting frame 7 to rotate synchronously downward to the vertical state, and lift the entire equipment off the foundation 2 through the casters 71 to complete the demolding. S8. Base adjustment assembly inspection and fine-tuning operation: Check the fixed status of the base adjustment assembly 3. If the position needs to be adjusted when installing the metal bracket 4 later, loosen the nut of the J-type anchor bolt 101, fine-tune the position of the round plate 3042 of the adjustment cylinder seat 304 in the adjustment groove 3011, align the metal bracket 4, tighten the nut again, and tighten the internal hex bolt 3013 on the side wall of the base plate 301 so that its screw head is inserted into the annular groove 3045 of the round plate 3042 to form a radial limit fixation of the round plate 3042.
