Description

Technical Field

[0001] This invention relates to the field of rooftop photovoltaic installation technology, and more specifically, to a method for installing prefabricated photovoltaic roof light-transmitting and smoke-exhausting structural units. Background Technology

[0002] The prefabricated photovoltaic roof light-transmitting and smoke-exhausting structural unit hoisting construction method is a professional construction technology for hoisting and positioning prefabricated roof units that integrate photovoltaic power generation, light transmission, and fire-fighting smoke exhaust functions using lifting equipment. Its core is to integrate the multiple functions required by the roof (power generation, light transmission, and smoke exhaust) into standardized prefabricated units in the factory, and then achieve efficient and high-quality roof assembly through precise hoisting.

[0003] By refining the roof structure into prefabricated Z-shaped panels, which are then processed in the factory and hoisted on-site, and connected to the main structure using grouting material, the on-site erection and dismantling of support frames is avoided. The upper part of the Z-shaped panels is equipped with motorized skylights and smoke exhaust windows and flexible photovoltaic modules, while the lower indoor space is equipped with lighting fixtures and smoke-detecting sprinklers, achieving functions such as lighting, ventilation, and photovoltaic power generation. However, the roof project is an important part of the building envelope system, and traditional design and construction have disadvantages such as high energy consumption, single function, and complex construction procedures. Therefore, a hoisting construction method for prefabricated photovoltaic roof light-transmitting and smoke exhaust structural units is provided. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for hoisting and constructing a prefabricated photovoltaic roof light-transmitting and smoke-exhausting structural unit, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a prefabricated photovoltaic roof light-transmitting and smoke-exhausting structural unit, including a base, on which two sets of hoisting components are provided; The hoisting assembly includes a slide seat mounted on top of the base, a rotatable turntable mounted on top of the slide seat, a support brace mounted on top of the turntable, an angle-adjustable reinforcing frame hinged to the top of the support brace, and an adjustable-position reinforcing crossbar mounted at one end of the reinforcing frame. The end of the reinforcing crossbar away from the reinforcing frame is provided with a first lifting clamp, and a second lifting clamp is provided on the first lifting clamp. The first and second lifting clamps are arranged opposite to each other and are rotatably connected by a limiting shaft. The bottom ends of the first and second lifting clamps are both fixedly provided with clamping rods, and each clamping rod is provided with an anti-disengagement hook on one side of its bottom.

[0006] Optionally, in one possible implementation, an iron chain is fixedly provided at the end of the reinforcing crossbar away from the reinforcing frame, and a limit hook is provided at the bottom of the iron chain. The top ends of the first and second lifting clamps are both hinged with hinge members, which are hooked onto the limit hooks. A limit torsion spring that abuts against the outside of the hinge member is provided at the top of the inner wall of the limit hook. Reinforcing inclined plates are provided on both sides of the supporting inclined bar, and the bottom ends of each of the reinforcing inclined plates are bolted to the turntable. A support is hinged to one side of the bottom of the supporting inclined bar, and a hydraulic rod is bolted to the top of the support. The top end of the hydraulic rod extends to the bottom of the reinforcing frame and is hinged to the reinforcing frame. Optionally, in one possible implementation, a plurality of limiting holes are provided through one side of the reinforcing frame, and a limiting pin that abuts against the reinforcing crossbar is inserted into one of the limiting holes. A motor is installed on one side of the turntable by bolts. A gear is provided at the output end of the motor. The gear is located outside the slide and meshes with the slide. An electric slide rail is provided at the top of the base. The slide is located at the top of the electric slide rail and is slidably connected to the electric slide rail. A plurality of supporting columns are provided on both sides of the bottom of the base, and a supporting wheel is provided at the bottom of the base. A hoisting construction method, using the above-mentioned prefabricated photovoltaic roof light-transmitting and smoke-exhausting structural unit, includes the following steps; Step 1: The gear at the output end of the motor meshes with the outer gear ring of the slide block, driving the turntable and the upper support inclined rod, reinforcing frame and other components to rotate, so that the first lifting clamp and the second lifting clamp are aligned with the direction of the workpiece lifting ear plate; Step 2, control the extension and retraction of the hydraulic rod: When the hydraulic rod extends, its top pushes the reinforcing frame to rotate upward around the hinge point at the top of the supporting diagonal rod, increasing the angle between the reinforcing frame and the horizontal plane; Step 3: Push the reinforcing crossbar along the length of the reinforcing frame so that the first and second lifting clamps can just contact the lifting ear plates on both sides of the workpiece. Manually operate the first and second lifting clamps to rotate and open them around the limiting axis, and align the bottom clamping rod with the lifting ear plate of the workpiece. Step 4: The anti-disengagement hook is attached to the inside of the lifting lug; at the same time, the hinge at the top of the lifting clamp is hooked onto the limit hook, and the limit torsion spring abuts against the outside of the hinge to prevent it from disengaging, thus completing the clamping and fixing of the workpiece. Step 5: By adjusting the electric slide rail, motor, and hydraulic rod in real time, ensure that the workpiece remains horizontal or in a preset tilt position; when the workpiece is lifted above the roof installation position, gradually adjust the position to align the workpiece with the installation base, slowly lower it and complete the docking and fixing, and finally complete the hoisting operation of a single unit.

[0007] The technical effects and advantages of this invention are as follows: This invention achieves precise adjustment of the hoisting position, direction, angle, and radius by using an electric slide rail to drive the slide block to slide laterally, a motor to drive the turntable to rotate, a hydraulic rod to adjust the angle of the reinforcing frame, and a limit pin to adjust the extension length of the reinforcing crossbar. It can adapt to the hoisting needs of different roof slopes and different sizes of photovoltaic light-transmitting and smoke-exhausting units, and solves the problem of insufficient adjustment flexibility of traditional hoisting equipment. The first and second lifting clamps of this invention form a scissor-type clamping structure through a limiting shaft. With the bottom anti-disengagement hook, they can firmly hook the lifting ear plate of the workpiece and prevent the workpiece from falling off during the lifting process. On the other hand, the cooperation between the hinge and the limiting hook and the counteracting action of the limiting torsion spring can prevent the lifting clamp from accidentally separating from the reinforcing crossbar. The dual safety design significantly improves the stability and safety of the lifting operation. The hoisting components of this invention adopt modular assembly, which facilitates rapid on-site installation and subsequent maintenance. At the same time, automated adjustment is achieved through automated components such as electric slide rails, motors, and hydraulic rods, reducing manual operation and shortening unit hoisting time. This solves the problems of low efficiency caused by reliance on manual adjustment in traditional hoisting. Furthermore, the reinforcing inclined plates on both sides of the support rod form a triangular stable structure, which can distribute the hoisting load to the turntable. The base is fixed to the ground through support columns, and with the bottom support wheels, it can quickly switch between moving and fixed positions, which can ensure the overall stability during hoisting and is also suitable for heavy photovoltaic light-transmitting and smoke-exhausting units. In summary, it can achieve precise adjustment of the hoisting position, direction, angle, and radius in all directions, and can adapt to the hoisting needs of roofs with different slopes and photovoltaic light-transmitting and smoke-exhausting units of different sizes. It solves the problem of insufficient adjustment flexibility of traditional hoisting equipment. The first hoisting clamp and the second hoisting clamp form a scissor-type clamping structure through the limiting shaft. With the bottom anti-disengagement hook, it can firmly hook the workpiece hoisting ear plate to prevent the workpiece from falling off during hoisting. On the other hand, the cooperation between the hinge and the limiting hook and the counteracting action of the limiting torsion spring can prevent the hoisting clamp from accidentally separating from the reinforcing crossbar. The dual safety design significantly improves the stability and safety of hoisting operations. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] This embodiment discloses a prefabricated photovoltaic roof light-transmitting and smoke-exhausting structural unit, suitable for the integrated installation of photovoltaic modules and light-transmitting and smoke-exhausting systems on the roofs of large industrial plants, commercial complexes, etc., and its structure is shown in the attached figure. Figure 1 As shown, it includes a base 1 and two sets of hoisting components symmetrically arranged on the base 1, which can realize the stable hoisting and precise positioning of the prefabricated photovoltaic light-transmitting and smoke-exhausting unit.

[0017] As attached Figure 1 As shown, the base 1 can be formed by welding steel plates. Several support columns 24 are symmetrically arranged on both sides of the bottom of the base 1. The bottom ends are fixed to the ground by expansion bolts to stabilize the overall structure during hoisting operations. Several support wheels with brakes are also provided at the four corners of the bottom of the base 1 to facilitate the movement of the equipment when not in operation.

[0018] Two parallel electric slide rails 23, model LGB-1500, are laid along the length of the top of the base 1 and are fixed to the base 1 with bolts. The electric slide rails 23 can be driven by a PLC control system to slide the slide block 2 along the rails, so as to achieve precise adjustment of the lateral position of the hoisting component.

[0019] The specific structure of each hoisting assembly is shown in the attached figure. Figure 2 As shown, it includes a slide block 2, a turntable 3, a support diagonal bar 4, a reinforcing frame 5, a reinforcing crossbar 6, and a lifting clamp assembly. The components work together to achieve multi-dimensional adjustment of the lifting angle and position.

[0020] Slide 2 and Turntable 3: The bottom of slide 2 is fixedly connected to the slider of electric slide rail 23, and the top is mounted with a turntable 3 that can rotate 360° via a bearing seat. A drive motor 21, a servo motor of model SGM7J-04AFC6S, is bolted to one side of the turntable 3. A gear 22 is keyed to its output end, and the gear 22 meshes with the gear ring on the outside of slide 2. By driving the gear 22 to rotate in both forward and reverse directions through the motor 21, the turntable 3 can be rotated, realizing the adjustment of the hoisting direction. The adjustment angle can be fed back in real time through the motor encoder.

[0021] A support brace 4 is welded to the top of the turntable 3 to enhance its stability. Reinforcing plates 16 are symmetrically arranged on both sides of the support brace 4. The bottom end of the reinforcing plates 16 is fixed to the turntable 3 by bolts to form a triangular stable structure, which can distribute the hoisting load to the turntable 3.

[0022] A support 17 is hinged to one side of the bottom of the support rod 4. A hydraulic rod 18 is bolted to the top of the support 17, and its top extends to the bottom of the reinforcing frame 5 and is hinged to the reinforcing frame 5. This allows the reinforcing frame 5 to rotate around the hinge point at the top of the support rod 4, thereby adjusting the angle to meet the hoisting requirements of different roof slopes.

[0023] The reinforcing frame 5 is a rectangular steel structure frame with several limiting holes 19 evenly distributed along its length on one side for adjusting the extension length of the reinforcing crossbar 6. One end of the reinforcing crossbar 6 is inserted into the reinforcing frame 5 and fixed by inserting a limiting pin 20 into the corresponding limiting hole 19. The extension length can be adjusted within the range of 0-600mm to accommodate the hoisting of units of different sizes.

[0024] As attached Figure 3 As shown, a chain 12 is welded to the end of the reinforcing crossbar 6 away from the reinforcing frame 5, and a limit hook 13 is connected to the bottom of the chain 12. A limit torsion spring 14 is installed on the top of the inner wall of the limit hook 13 to limit the disengagement of the hinge 15.

[0025] The first lifting clamp 7 and the second lifting clamp 8 are rotatably connected by a limiting shaft 9, forming an opening and closing structure similar to "scissors". (See attached image) Figure 4 As shown, when an external force is applied, the first lifting clamp 7 and the second lifting clamp 8 can rotate around the limiting shaft 9 to achieve an opening and closing angle adjustment of 0-60°. Both clamps are welded to their bottom ends with clamping rods 10, and anti-disengagement hooks 11 are welded to one side of the bottom of the clamping rods 10 to hook the lifting ear plates of the photovoltaic smoke exhaust unit and prevent them from falling off during the lifting process.

[0026] The top ends of the first lifting clamp 7 and the second lifting clamp 8 are both hinged to the hinge 15 by a pin. The hinge 15 is hooked on the limit hook 13, and the limit torsion spring 14 abuts against the outside of the hinge 15, which can prevent the hinge 15 from accidentally disengaging from the limit hook 13, thereby further improving the safety of lifting.

[0027] The specific working principle is as follows: push the base 1 to move its bottom support wheel to the side of the area to be hoisted, and lock the support wheel brake; fix the support column 24 at the bottom of the base 1 to the ground with expansion bolts to ensure the overall stability of the equipment during hoisting and avoid shaking.

[0028] Start the electric slide rail 23, and its slider will drive the slide block 2 to slide laterally along the rail, so that the two sets of lifting components are moved to the lateral position corresponding to the lifting ear plates on both sides of the photovoltaic light-transmitting and smoke-exhausting unit to be lifted. The sliding distance of the slide block 2 is precisely controlled by the PLC control system to ensure that the lifting clamp is aligned with the lifting point of the workpiece.

[0029] Start the motor 21 on one side of the turntable 3. The gear 22 at the output end of the motor 21 meshes with the outer gear ring of the slide block 2, driving the turntable 3 and the upper support diagonal rod 4, reinforcing frame 5 and other components to rotate. Adjust the orientation of the hoisting components so that the first hoisting clamp 7 and the second hoisting clamp 8 are facing the direction of the workpiece hoisting ear plate. The rotation angle can be fed back in real time through the motor encoder.

[0030] Controlling the extension and retraction of hydraulic rod 18: When hydraulic rod 18 extends, its top pushes the reinforcing frame 5 to rotate upward around the hinge point at the top of the supporting diagonal rod 4, increasing the angle between the reinforcing frame 5 and the horizontal plane; when hydraulic rod 18 retracts, the reinforcing frame 5 rotates downward, decreasing the angle. By adjusting this angle, the tilt angle between the lifting clamp and the workpiece to be lifted is matched, such as the roof slope, ensuring that the posture of the workpiece after lifting is consistent with the roof installation angle.

[0031] According to the workpiece size, pull out the limiting pin 20 on the reinforcing frame 5, push the reinforcing crossbar 6 to move along the length of the reinforcing frame 5, and adjust its extension length; after the length is suitable, insert the limiting pin 20 into the corresponding limiting hole 19 and fix it, so that the first lifting clamp 7 and the second lifting clamp 8 can just contact the lifting ear plates on both sides of the workpiece to ensure the lifting force is balanced.

[0032] The first lifting clamp 7 and the second lifting clamp 8 are manually operated to rotate and open around the limiting shaft 9, and the bottom clamping rod 10 is aligned with the lifting ear plate of the workpiece. After the external force is released, the lifting clamps close naturally under their own weight and the pulling force of the workpiece, and the anti-disengagement hook 11 hooks the inner side of the lifting ear plate. At the same time, the hinge 15 at the top of the lifting clamp is hooked on the limiting hook 13, and the limiting torsion spring 14 abuts against the outer side of the hinge 15 to prevent it from disengaging, thus completing the clamping and fixing of the workpiece.

[0033] The lifting equipment connects the reinforcing crossbar 6 via the iron chain 12 and slowly lifts the hoisting component. During the lifting process, the electric slide rail 23, motor 21, and hydraulic rod 18 are adjusted in real time to ensure that the workpiece remains horizontal or in a preset tilt position. When the workpiece is lifted above the roof installation position, the position is gradually adjusted to align the workpiece with the installation base, and it is slowly lowered and docked and fixed, thus completing the hoisting operation of a single unit.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
