Description

Technical Field

[0001] This invention belongs to the field of clamp straightening technology, specifically a photovoltaic bracket clamp straightener for use on construction sites. Background Technology

[0002] In photovoltaic (PV) power generation systems, clamps are crucial connectors used to connect and secure various components of the PV mounting system. During the installation process at the PV construction site, after processes such as bending during production, hot-dip galvanizing for corrosion protection, warehousing, transportation, and loading / unloading, clamps are prone to deformation defects such as curvature deviations, ellipses, gaps, and lug warping. This results in the clamps failing to fit tightly against the PV mounting system after installation. This problem not only reduces the installation connection strength of the clamps but also compromises the safety of the PV equipment after installation, ultimately significantly reducing the actual performance of the clamps.

A drive spring is sleeved on a drive square post; one end of the drive spring is fixedly connected to the drive block, and the other end is fixedly connected to the bent square plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) When the inner wall of the pressure arc block contacts the outer wall of the clamp, the pressure arc block is limited and cannot move further, causing the pressure horizontal plate to continue moving on the pressure cylinder, so that the pressure spring is in a buffer state, further strengthening the contact strength between the pressure arc block and the clamp, and preventing deformation or bending of the clamp due to insufficient pressure. The clamp cannot return to the state of fitting with the bracket due to insufficient pressure. It is worth mentioning that the second limiting plate is used to control the maximum movement position of the pressure horizontal plate on the pressure cylinder, preventing the pressure applied by the pressure arc block to the clamp from being too large and causing damage. This further improves the clamp's performance and lifespan, while also making the machine more efficient. This device can repair and straighten deformed and bent clamps, preventing non-human-caused deformation defects such as arc deviation, ellipticity, and opening during storage, transportation, loading and unloading, and delivery to the construction site. Furthermore, the repair and straightening of clamp deformation is performed after installation, ensuring a tight fit between the clamp and the photovoltaic support. This not only improves the installation connection strength of the clamp but also effectively guarantees the safety of the photovoltaic equipment after installation, ultimately significantly improving the actual performance of the clamp. It also enhances the effectiveness of the machine used to straighten clamp deformation. Moreover, this straightening and repair method can be operated by hand, reducing the limitations of machine use. (2) The two drive racks move relative to each other, causing them to move at the upper limit of the auxiliary base via the auxiliary sliding column. This causes the moving drive racks to drive the bending square plates to move, causing the two bending square plates to move relative to each other. Under the action of the drive column and the drive spring, the drive blocks move, causing the two drive blocks to move closer to the top and bottom of the clamped clamp, respectively. This causes the buffer pads on the drive blocks to contact the clamp, allowing the two drive blocks to further clamp the clamp. This also allows the drive blocks to contact the top and bottom of the clamp before the pressure arc block contacts the outer wall of the clamp, for positioning and setting. The clamping mechanism prevents the pressure arc block from dislodging during clamp repair, thus avoiding repair and correction failures and improving the clamp repair effect. Simultaneously, when the inner wall of the pressure arc block contacts the outer wall of the clamp, pressure is applied, causing the clamp to bend and deform under pressure. This deformation generates wobbling, which is absorbed and reduced by the buffering force of the drive spring and buffer pad. This improves the stability of the clamp repair and correction, thereby enhancing its correction effect and increasing the installation and connection strength of the clamp, further improving its usability and reducing the limitations of machine use. (3) The pressure arc block moves close to the clamp until the inner wall of the pressure arc block contacts the outer wall of the clamp and applies pressure to the outer wall of the clamp, so that the bent and deformed parts of the clamp are pressed and fit against the bracket, thus avoiding the clamp not fitting against the bracket after installation, which would reduce the performance of the clamp and the photovoltaic bracket. This improves the installation and fastening effect of the clamp and ensures the performance, life and safety of the photovoltaic equipment on the bracket. At the same time, when the pressure horizontal plate moves the pressure arc block, the pressure horizontal plate moves at the upper limit of the U-shaped rod through the pressure sliding column. This not only supports the pressure arc block and the pressure horizontal plate, but also improves the stability of their movement, thus strengthening and improving the repair and correction operation of the clamp by the pressure arc block. (4) When the limiting pin on the limiting plate passes through the pressure cylinder, it connects with one of the limiting slots, thereby limiting the positioning cylinder and completing the installation operation of the pressure arc block. The pressure arc block for repairing and correcting the deformed clamp can be installed on the moving pressure cylinder for use, reducing the limitations of the machine's use. It is worth mentioning that the number of limiting slots is set to several, so that the pressure arc block can be installed at different distances from the bracket, which is convenient for the machine to be used according to different sizes of brackets, further improving the machine's use effect. At the same time, when the positioning cylinder is limited, the positioning spring in the buffer state cannot be reset, and the resulting elastic force acts on the positioning cylinder, thereby increasing the contact strength and friction between the limiting slot and the limiting pin, and preventing the pressure block from being installed due to non-human factors during use. The machine addresses the issue of dislocation or wobbling of the arc blocks, improving installation efficiency. This allows for quick and convenient installation and removal of the pressure arc blocks. Different shapes and sizes of pressure arc blocks, such as arc-shaped and square ones, can be used to repair and correct clamps of various shapes, depending on different needs and conditions. The replacement process can be completed without any tools, reducing limitations while improving correction effectiveness and efficiency. The machine can perform targeted repair and correction for clamps of different sizes and shapes, ensuring a perfect fit between the pressure arc blocks and the clamps. This improves the repair and correction effect and precision, ensuring a perfect fit between the repaired clamps and the bracket. This guarantees and enhances the installation connection strength of the clamps, ensuring the safety of the photovoltaic equipment and its subsequent use. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Implementation examples, by Figures 1 to 12The invention includes a bracket; a U-shaped rod 1; two spliced ​​clamps mounted on the bracket; the bracket being located within an opening in the U-shaped rod 1; a handrail 2 being mounted on the side of the U-shaped rod 1 away from its opening; a pressure-applying correction device being provided on the U-shaped rod 1 for correcting bending and deformation of the clamps after installation; the pressure-applying correction device includes two pressure arc blocks 3 located on both sides of the bracket; the outer wall of the clamp is located on the moving path of the inner wall of the pressure arc blocks 3; and a pressure cross plate 4 being disposed within the opening of the U-shaped rod 1; the pressure cross plate 4 is located within the pressure arc blocks 3. Between block 3 and the inner wall of U-shaped rod 1; displacement groove 7, set on the inner wall of U-shaped rod 1; displacement screw 8, installed in displacement groove 7; displacement screw 8 and bracket are vertically matched; displacement screw 8 is provided with two opposite threaded areas; power source 9, connected to the outer wall of U-shaped rod 1; the output end of power source 9 is connected to displacement screw 8; displacement block 10; two displacement blocks 10 are symmetrically connected to displacement screw 8; the two threaded areas are threadedly matched with the two displacement blocks 10 respectively; displacement blocks 10 and displacement groove 7 are fitted together, and the two are in sliding fit. An extension plate 11 is connected to a movable block 10 on one side and to a pressure plate 4 on the other side; a fixed base 12 is installed on one of the extension plates 11; a first limiting plate 19 is installed on the end of the pressure cylinder 5 away from the pressure arc block 3; a second limiting plate 20 is installed on the pressure cylinder 5; the second limiting plate 20 is located between the pressure arc block 3 and the pressure plate 4; the second limiting plate 20 is located on the moving path of the pressure plate 4; a limiting base 13 is located between the second limiting plate 20 and the pressure plate 4; a pressure spring 21 is sleeved on the pressure cylinder 5; one end of the pressure spring 21 is fixedly connected to the first limiting plate 19, and the other end is fixedly connected to the pressure plate 4; a pressure sliding column 25 is installed on the side of the pressure plate 4 away from the pressure arc block 3; the pressure sliding column 25 is connected through the side of the U-shaped rod 1 near the support; the pressure sliding column 25 and the U-shaped rod 1 are in sliding engagement; After the two semi-circular clamps are assembled and installed on the bracket, the U-shaped rod 1 on it is lifted synchronously by holding the handle 2 and moved to the installed clamp position, so that the bracket and its clamps are located in the opening of the U-shaped rod 1. At this time, the power source 9 is started, and its output end drives the displacement screw 8 to rotate. Since the two ends of the displacement screw 8 have opposite threads, the two threaded displacement blocks 10 are limited to move relative to each other in the displacement groove 7. Under the action of the extension plate 11, they drive the two pressure plates 4 to move relative to each other, so that the two pressure plates 4 located on both sides of the bracket... All of these move close to the clamps installed on the bracket, causing the pressure plate 4, under the action of the control and replacement mechanism, to move the pressure arc block 3 installed on the pressure plate 4 closer to the clamp until the inner wall of the pressure arc block 3 contacts the outer wall of the clamp and applies pressure to the outer wall of the clamp. This causes the bent and deformed parts of the clamp to be pressed and fit against the bracket, preventing the clamp from failing to fit against the bracket after installation, which would reduce the performance of the clamp and the photovoltaic bracket. This improves the installation and fastening effect of the clamp and also ensures the performance, lifespan and safety of the photovoltaic equipment on the bracket. At the same time, when the pressure plate 4 drives the pressure arc block 3 to move, the pressure plate 4 moves at the upper limit of the U-shaped rod 1 through the pressure sliding column 25, which not only supports the pressure arc block 3 and the pressure plate 4, but also improves the stability of their movement, thus strengthening and improving the repair and correction operation of the clamp by the pressure arc block 3. It is worth mentioning that, since the pressure arc block 3 is installed on the pressure cylinder 5 through the control and replacement mechanism, and the pressure cylinder 5 is in sliding fit with the pressure horizontal plate 4, in the early stage when the pressure arc block 3 does not receive resistance, the moving pressure horizontal plate 4 is under the action of the first limit plate 19 and the pressure spring 21. At this time, the pressure spring 21 does not overcome the elastic force, so the pressure horizontal plate 4 and the pressure arc block 3 move together. When the inner wall of the pressure arc block 3 contacts the outer wall of the clamp, the pressure arc block 3 is limited and cannot continue to move, so that the pressure horizontal plate 4 continues to move on the pressure cylinder 5, so that the pressure spring 21 is in a buffer state, further strengthening the contact strength between the pressure arc block 3 and the clamp, and avoiding the clamp from deforming or bending due to insufficient contact strength, which cannot return to the state of fitting with the bracket due to insufficient pressure. It is worth mentioning that the second limiting plate 20 is used to control the maximum movement position of the pressure plate 4 on the pressure cylinder 5, preventing excessive pressure from the pressure arc block 3 on the clamp and causing damage. This further improves the clamp's performance and lifespan, while also enabling the machine to repair and correct deformed or bent clamps. This avoids non-human-caused deformation defects such as arc deviation, ellipticity, and opening during storage, transportation, loading and unloading, and delivery to the construction site. Furthermore, the repair and correction of clamp deformation is performed after installation, ensuring a tight fit between the clamp and the photovoltaic bracket. This not only improves the installation connection strength of the clamp but also effectively guarantees the safety of the photovoltaic equipment after installation, ultimately significantly improving the actual performance of the clamp. Simultaneously, it enhances the effectiveness of the machine used to correct clamp deformation. Moreover, this correction and repair method can be operated by hand, reducing the machine's limitations.

[0020] The positioning and replacement mechanism of this embodiment is disposed on the pressure-applying horizontal plate 4; the positioning and replacement mechanism is used to conveniently replace pressure-applying arc blocks 3 of different shapes and sizes; the positioning and replacement mechanism includes a pressure-applying cylinder 5, which is connected through the pressure-applying horizontal plate 4 to the side near the pressure-applying arc block 3; the pressure-applying cylinder 5 and the pressure-applying horizontal plate 4 are slidably engaged; a limiting base 13 is installed on both sides of the pressure-applying cylinder 5; a limiting cylinder 14 is connected to the limiting base 13; a limiting horizontal plate 15 is located on the outer wall of the pressure-applying cylinder 5; the limiting horizontal plate 15 is connected through the limiting cylinder 14 to the side near the pressure-applying cylinder 5; the limiting cylinder 14 and the limiting horizontal plate 15 are slidably engaged; a limiting insert 16 is installed on the side of the limiting horizontal plate 15 near the pressure-applying cylinder 5; a positioning cylinder 17 is installed on the side of the pressure-applying arc block 3 away from the bracket; the positioning cylinder 17... 7. The end away from the pressure-applying arc block 3 is fitted inside the pressure-applying cylinder 5; the pressure-applying cylinder 5 and the positioning cylinder 17 are in sliding fit; the positioning spring 18 is set inside the pressure-applying cylinder 5; one end of the positioning spring 18 is fixedly connected to the bottom surface inside the pressure-applying cylinder 5, and the other end is located on the moving path of the end point of the positioning cylinder 17; the limiting slot 22 is set through the positioning cylinder 17 on the side near the limiting horizontal plate 15; several limiting slots 22 are arranged at equal intervals; the limiting insert 16 passes through the pressure-applying cylinder 5 and is connected to one of the limiting slots 22; the third limiting plate 23 is fixedly connected to the end of the limiting cylinder 14 away from the limiting base 13; the limiting spring 24 is sleeved on the limiting cylinder 14; one end of the limiting spring 24 is fixedly connected to the third limiting plate 23, and the other end is fixedly connected to the limiting horizontal plate 15; By pulling the limiting horizontal plate 15 outward, it moves to the upper limit of the limiting cylinder 14, so that the limiting spring 24 is in a buffer state. Then, the limiting pin 16 on the limiting horizontal plate 15 is disengaged from the pressure cylinder 5 and is no longer connected to one of the limiting slots 22, thereby releasing the limiting setting of the positioning cylinder 17. This allows the positioning spring 18, which was originally in a buffer state, to reset. The elastic force brought about by the reset acts on the positioning cylinder 17, thereby pushing it out of the pressure cylinder 5. This allows the pressure arc block 3 on the positioning cylinder 17 to be disengaged from the pressure cylinder 5, completing the disassembly of the pressure arc block 3. When it is necessary to install the pressure arc block 3, the positioning cylinder 17 on it is aligned with the pressure cylinder 5 and moved, so that the positioning cylinder 17 moves within the pressure cylinder 5 until the positioning cylinder 17 contacts the end point of the positioning spring 18 located inside the pressure cylinder 5. If pressure is continuously applied to the pressure arc block 3 at this time, the positioning cylinder 17 on it will continue to move within the pressure cylinder 5, so that the positioning spring 18 is in a buffer state. When the pressure arc block 3 moves to the appropriate and required position, it indicates that it has reached the installation position. By releasing the original outward pulling limit plate 15, the limit spring 24, which was originally in the buffer state, is reset and moves, and drives the limit plate 15 to reset and move on the limit cylinder 14. This allows the limit pin 16 on the limit plate 15 to pass through the pressure cylinder 5 and connect with one of the limit slots 22, thereby limiting the positioning cylinder 17 and completing the installation operation of the pressure arc block 3. The pressure arc block 3 for repairing and correcting deformed clamps can be installed on the moving pressure cylinder 5 for use, reducing the limitations of machine use. It is worth mentioning that the number of limiting slots 22 is set in a certain way, so that the pressure arc block 3 can be installed at different distances from the bracket, which makes it convenient for the machine to be used with brackets of different sizes, and further improves the machine's performance. At the same time, when the positioning cylinder 17 is limited, the positioning spring 18, which is in a buffer state, cannot be reset. The resulting elastic force acts on the positioning cylinder 17, thereby increasing the contact strength and friction between the limiting slot 22 and the limiting pin 16, preventing the pressure arc block 3 from dislodging or shaking due to non-human factors during use, and improving its installation effect. This allows for quick and convenient installation and removal of the pressure arc block 3, and also enables... Depending on different needs and conditions, pressure blocks 3 of different shapes and sizes, such as arc-shaped and square, are used to repair and correct clamps of different shapes. The operation can be completed without the aid of any tools during the replacement process, reducing the limitations of use while improving the correction effect and efficiency. The machine can perform targeted repair and correction according to clamps of different sizes and shapes, ensuring that the pressure blocks 3 used for repair and correction can fit perfectly with the clamps, thereby improving the effect and accuracy of repair and correction. This ensures that the repaired clamps fit perfectly with the bracket, thus ensuring and improving the installation connection strength of the clamps and guaranteeing the safety of the photovoltaic equipment in subsequent use.

[0021] The energy dissipation and vibration reduction unit of this embodiment is installed on the U-shaped rod 1. The energy dissipation and vibration reduction unit is used to reduce the impact force generated during the straightening process of the clamp. The energy dissipation and vibration reduction unit includes a drive gear 6, which is installed on the side of the U-shaped rod 1 near the handrail 2; a drive base 26, which is installed on the side of the U-shaped rod 1 near the handrail 2; a drive shaft 27, which is connected to the drive base 26; and a spring 28, which is connected to one end of the drive shaft 27. The end of the spring 28 is fixedly connected to the drive base 26. The first bevel tooth 29 is installed at the other end of the drive shaft 27; the winding roller 30 is connected to the drive shaft 27; the guide roller group 31 is installed on the U-shaped rod 1; the cable 32 is connected at one end to the fixed square seat 12, and the other end passes around the guide roller group 31 and is wound and connected to the winding roller 30; the second bevel tooth 33 is installed on the side of the drive gear 6 away from the U-shaped rod 1; the second bevel tooth 33 is meshed with the first bevel tooth 29; the drive rack 34 is meshed with the drive gear 6. Two drive racks 34 are located on both sides of the drive gear 6; auxiliary sliding columns 35 are installed on the drive racks 34; an auxiliary base 36 is fixedly connected to the U-shaped rod 1; the auxiliary base 36 is connected through the auxiliary sliding column 35, and the two are in sliding engagement; a bent square plate 37; the two bent square plates 37 are respectively connected to the two drive racks 34; the two bent square plates 37 are respectively located at the top and bottom of the clamp; a drive column 38 is connected through the bent square plate 37 near the clamp; the bent square plate 37 and the drive column 38 are in sliding engagement; a drive block 39 is installed at the end of the drive column 38 near the clamp; a buffer pad 40 is connected to the side of the drive block 39 away from the drive column 38; the two drive blocks 39 are respectively located at the top and bottom of the clamp; the clamp is located on the moving path of the buffer pad 40; a drive spring 41 is sleeved on the drive column 38; one end of the drive spring 41 is fixedly connected to the drive block 39, and the other end is fixedly connected to the bent square plate 37; During the repair and correction process of the clamp, the handheld U-shaped rod 1 moves the pressure plate 4 closer to the clamp, causing the extension plate 11 on it to move synchronously with the fixed seat 12. Under the action of the cable 32 and the guide roller group 31, the winding roller 30 is driven to unwind and rotate. At the same time, the drive shaft 27 on it drives the first bevel tooth 29 to rotate, and the spring spring 28 on the drive shaft 27 is in a buffer state, so that when the pressure plate 4 moves back to its original position, it no longer exerts tension on the spring spring 28. This allows the winding roller 30 to rotate back to its original position and rewind the cable 32 onto the winding roller 30 for the next repair and correction operation. When the first bevel tooth 29 rotates while the spring 28 is in a buffered state, it meshes with the second bevel tooth 33, causing the drive gear 6 to rotate. This meshes with the two drive racks 34, causing them to move relative to each other. The drive racks 34 then move to the upper limit of the auxiliary base 36 via the auxiliary slide column 35. This causes the moving drive racks 34 to move the bending square plate 37, which in turn moves relative to each other. Under the action of the drive column 38 and the drive spring 41, the drive blocks 39 move, bringing them closer to the top and bottom of the assembled clamp. This allows the buffer pads 40 on the drive blocks 39 to contact the clamp, further clamping the clamp. The drive blocks 39 can also contact the top and bottom of the clamp before the pressure arc block 3 contacts the outer wall of the clamp, positioning it for clamping. This prevents the pressure arc block 3 from dislodging during clamp repair, thus improving the clamp repair and correction effect. Simultaneously, when the inner wall of the pressure arc block 3 contacts the outer wall of the clamp, pressure is applied to the outer wall of the clamp. The clamp is bent and deformed under pressure, and shaking occurs during the deformation process. Through the buffering force of the drive spring 41 and the buffer pad 40, the impact force generated by the shaking during the clamp correction process can be absorbed and reduced, thereby improving the stability of the clamp during repair and correction, thus improving its correction effect, enhancing the installation and connection strength of the clamp, further improving its use effect, and reducing the limitations of machine use.
