Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket technology, and more specifically, to a straightening machine for processing photovoltaic brackets. Background Technology

[0002] A photovoltaic (PV) support system is a structural system used to support and fix solar photovoltaic (PV) modules, ensuring that the PV panels receive solar radiation at the optimal angle, thereby improving power generation efficiency. It is usually installed on the ground, roof or other open areas and has good resistance to wind, snow and corrosion to cope with various climatic conditions.

[0003] Photovoltaic support structures are mainly composed of columns, beams, diagonal braces, and connectors. The materials used are mostly aluminum alloy, galvanized steel, or stainless steel to ensure durability. However, during the manufacturing process of photovoltaic support structures, the materials may be deformed by bending, twisting, or other defects due to improper transportation, storage, or processing, which will affect the installation accuracy and stability of the support structure. Therefore, it is necessary to correct these defects.

[0004] Currently, U-shaped steel is widely used in photovoltaic brackets because its cross-sectional design gives it high bending and torsional resistance, while its relatively light weight makes it easy to transport and install. However, current straightening machines usually correct deformed materials by mechanical force to restore them to a flat and straight state. However, when straightening U-shaped steel, due to its shape characteristics, the straightening machine is prone to bending it inward when straightening the outer wall of the U-shaped steel, which can lead to material damage. Therefore, it is necessary to improve and optimize the straightening process. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a straightening machine for processing photovoltaic brackets, which solves the technical problem that U-shaped steel is prone to bending and deformation during straightening in the prior art.

[0006] According to one aspect, at least one embodiment of this disclosure provides a straightening machine for processing photovoltaic brackets, including a support platform, a limiting structure provided on the top of the support platform, the limiting structure including a telescopic groove opened in the middle of the limiting structure, second limiting grooves opened on both the front and rear sides of the telescopic groove, and first limiting grooves opened at both the left and right ends of the two sets of second limiting grooves.

[0007] The support platform has an inner lining structure in the middle, which includes a protective plate movably installed inside the second limiting groove. There are two sets of protective plates located on the left and right sides of the second limiting groove. Rollers are provided on the outer walls of the two sets of protective plates. The inner lining structure also includes a control block movably installed inside the telescopic groove. A lead screw is rotatably installed inside the telescopic groove. The lead screw and the control block are threaded together. A first motor is fixedly installed at the bottom of the support platform. The output shaft of the first motor is fixedly connected to the lead screw. A U-shaped steel is provided at the top of the support platform. The rollers on the left and right sides abut against the inner walls of the U-shaped steel. A straightening mechanism is provided on both the left and right sides of the top of the support platform.

[0008] For example, in at least one embodiment of this disclosure, a straightening machine for processing photovoltaic brackets is provided, which further includes: the straightening mechanism consists of two sets, including a straightening table movably installed inside the first limiting groove. The two sets of straightening tables are provided with movable grooves inside. A straightening plate is movably installed inside the movable groove. A pressure roller is rotatably installed at one end of the straightening plate, and the pressure roller and the outer wall of the U-shaped steel abut against each other.

[0009] For example, in at least one embodiment of this disclosure, a straightening machine for processing photovoltaic brackets is further provided, wherein a first hydraulic cylinder is fixedly installed on the outer wall of the straightening table, and the telescopic end of the first hydraulic cylinder extends through the interior of the movable groove and is fixedly connected to the straightening plate.

[0010] For example, in a straightening machine for processing photovoltaic brackets provided in at least one embodiment of this disclosure, a second motor is fixedly installed inside the straightening plate, and two sets of synchronous pulleys are rotatably installed inside the straightening plate.

[0011] For example, in a straightening machine for processing photovoltaic brackets provided in at least one embodiment of this disclosure, there is a set of synchronous pulleys and the output shaft of the second motor that are fixedly connected, and another set of synchronous pulleys and the rotating shaft of the pressure roller are fixedly connected, and the two sets of synchronous pulleys are connected by a synchronous belt drive.

[0012] For example, in at least one embodiment of this disclosure, a straightening machine for processing photovoltaic brackets is provided, which further includes: a centering mechanism provided at the bottom of the support platform, the centering mechanism including a bottom shell fixedly installed at the bottom of the support platform, a first transmission plate provided on the left side inside the bottom shell, and a second transmission plate provided on the right side inside the bottom shell.

[0013] For example, in a straightening machine for processing photovoltaic brackets provided in at least one embodiment of this disclosure, the top of the first transmission plate and the second transmission plate both penetrate into the interior of the first limiting groove, and the first transmission plate and the second transmission plate are respectively fixedly connected to the left and right sets of straightening tables.

[0014] For example, in a straightening machine for processing photovoltaic brackets provided in at least one embodiment of this disclosure, two sets of gears are rotatably installed inside the bottom shell, two sets of racks are fixedly installed on the right side of the first transmission plate, and two sets of racks are also fixedly installed on the left side of the second transmission plate, with each pair of racks meshing with a gear.

[0015] For example, in a straightening machine for processing photovoltaic brackets provided in at least one embodiment of this disclosure, a second hydraulic cylinder is fixedly installed on the outer wall of the bottom shell, and the telescopic end of the second hydraulic cylinder extends into the interior of the bottom shell and is fixedly connected to the first transmission plate.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, by controlling the upward displacement of the block, the sloping surfaces on the left and right sides gradually push the two sets of protective plates to the sides. As the protective plates are pushed, the roller and the inner wall of the U-shaped steel abut against each other, protecting the inner wall of the U-shaped steel. Through the operation of the two sets of straightening mechanisms, the outer wall of the U-shaped steel is straightened. Compared with traditional devices, this device can protect the inner wall of the U-shaped steel through the inner lining structure when the straightening mechanism is straightening, effectively avoiding deformation of the U-shaped steel caused by excessive straightening force. At the same time, with the pressure applied by the straightening mechanism, the roller can also straighten the inner wall of the U-shaped steel, ensuring the straightening quality and efficiency.

[0018] 2. In this disclosure, the operation of the second hydraulic cylinder causes the two sets of transmission plates to move synchronously relative to each other, further shortening the distance between the two sets of straightening mechanisms. Compared with traditional devices, this device can simultaneously straighten the left and right ends of the U-shaped steel during straightening, and ensure that the U-shaped steel is always located in the center of the support platform during straightening, avoiding the offset and misalignment of the U-shaped steel. Through the operation of the second motor and the transmission of the synchronous belt, the pressure roller is rotated, realizing the automatic straightening of the U-shaped steel, reducing the workload and improving the straightening efficiency.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-7 As shown, it illustrates a straightening machine for processing photovoltaic brackets in one embodiment of the present disclosure, including a support platform 1, a limiting structure 6 provided on the top of the support platform 1, the limiting structure 6 including a telescopic groove 63 opened in the middle of the limiting structure 6, a second limiting groove 62 opened on both the front and rear sides of the telescopic groove 63, and a first limiting groove 61 opened at both the left and right ends of the two sets of second limiting grooves 62.

[0035] The support platform 1 has an inner lining structure 2 in the middle. The inner lining structure 2 includes a protective plate 21 that is movably installed inside the second limiting groove 62. There are two sets of protective plates 21 located on the left and right sides of the second limiting groove 62. Rollers 22 are provided on the outer walls of the two sets of protective plates 21. The inner lining structure 2 also includes a control block 25 that is movably installed inside the telescopic groove 63. A lead screw 24 is rotatably installed inside the telescopic groove 63. The lead screw 24 and the control block 25 are threaded together. A first motor 23 is fixedly installed at the bottom of the support platform 1. The output shaft of the first motor 23 is fixedly connected to the lead screw 24. A U-shaped steel 5 is provided at the top of the support platform 1. The rollers 22 on the left and right sides and the inner walls of the U-shaped steel 5 abut against each other. A straightening mechanism 3 is provided on both the left and right sides of the top of the support platform 1.

[0036] When the U-shaped steel 5 needs to be straightened, the operator first powers on the device and then places the U-shaped steel 5 on the support platform 1. At this time, the operator should ensure that the groove of the U-shaped steel 5 is locked on the top of the two sets of protective plates 21. Then, the operator controls the operation of the first motor 23 through the main control switch. The operation of the first motor 23 drives the lead screw 24 to rotate. The rotation of the lead screw 24 drives the control block 25, which is threadedly connected to it, to move along the telescopic groove 63. When the control block 25 moves upward, the slope surface 26 on the left and right sides of the control block 25 will abut against the protective plates 21 and move the two sets of protective plates 21 to the left and right ends along the second limit groove 62 until the roller 22 and the inner wall of the U-shaped steel 5 abut against each other. Then the operator can stop the first motor 23. At this time, the roller 22 on the left and right sets of protective plates 21 abut against the inner wall of the U-shaped steel 5, providing internal support for the U-shaped steel 5.

[0037] By controlling the upward displacement of the control block 25, the slope surfaces 26 on both sides gradually push the two sets of protective plates 21 to both sides. As the protective plates 21 are pushed, the roller 22 and the inner wall of the U-shaped steel 5 abut against each other, protecting the inner wall of the U-shaped steel 5. Through the operation of the two sets of straightening mechanisms 3, the outer wall of the U-shaped steel 5 is straightened. Compared with the traditional device, this device can protect the inner wall of the U-shaped steel 5 through the inner lining structure 2 when the straightening mechanism 3 is straightening, effectively avoiding deformation of the U-shaped steel 5 caused by excessive straightening force. At the same time, with the pressure applied by the straightening mechanism 3, the roller 22 can also straighten the inner wall of the U-shaped steel 5, ensuring the straightening quality and efficiency.

[0038] In some examples, the correction mechanism 3 has two sets, including a correction table 31 that is movably installed inside the first limiting groove 61. Both sets of correction tables 31 have a movable groove 32 inside. A correction plate 33 is movably installed inside the movable groove 32. A pressure roller 35 is rotatably installed at one end of the correction plate 33, and the pressure roller 35 and the outer wall of the U-shaped steel 5 abut against each other.

[0039] The design of the pressure rollers 35 allows two sets of pressure rollers 35 to straighten the outer wall of the U-shaped steel 5.

[0040] In some examples, a first hydraulic cylinder 34 is fixedly installed on the outer wall of the correction table 31. The telescopic end of the first hydraulic cylinder 34 extends into the interior of the movable groove 32 and is fixedly connected to the correction plate 33.

[0041] In some examples, a second motor 36 is fixedly installed inside the straightening plate 33, and two sets of synchronous pulleys 37 are rotatably installed inside the straightening plate 33.

[0042] In some examples, one set of synchronous pulleys 37 is fixedly connected to the output shaft of the second motor 36, and another set of synchronous pulleys 37 is fixedly connected to the rotating shaft of the pressure roller 35. The two sets of synchronous pulleys 37 are connected by a synchronous belt 38.

[0043] After the spacing between the two sets of straightening mechanisms 3 is adjusted, the pressure roller 35 and the outer wall of the U-shaped steel 5 come into contact with each other. The operator can start the first hydraulic cylinder 34. The telescopic end of the first hydraulic cylinder 34 will drive the straightening plate 33 to move along the movable groove 32. Further, the pressure roller 35 and the outer wall of the U-shaped steel 5 will abut against each other. The operator can control the straightening force of the pressure roller 35 on the U-shaped steel 5 through the first hydraulic cylinder 34. Finally, the operator starts the second motor 36. The operation of the second motor 36 will drive one set of synchronous pulleys 37 to rotate. However, the two sets of synchronous pulleys 37 are connected by a synchronous belt 38, so that the two sets of synchronous pulleys 37 rotate synchronously and drive the pressure roller 35 to rotate. As the pressure roller 35 rotates, the straightening mechanism 3 will straighten the U-shaped steel 5 and transport it at the same time.

[0044] The operation of the second hydraulic cylinder 46 causes the two sets of transmission plates to move synchronously relative to each other, further shortening the distance between the two sets of straightening mechanisms 3. Compared with traditional devices, this device can simultaneously straighten the left and right ends of the U-shaped steel 5 during straightening, and ensure that the U-shaped steel 5 is always located in the center of the support platform 1 during straightening, avoiding the offset and misalignment of the U-shaped steel 5. Through the operation of the second motor 36 and the transmission of the synchronous belt 38, the pressure roller 35 is rotated, realizing the automatic straightening of the U-shaped steel 5, reducing the workload and improving the straightening efficiency.

[0045] In some examples, the bottom of the support platform 1 is provided with a centering mechanism 4, which includes a bottom shell 41 fixedly installed on the bottom of the support platform 1. A first transmission plate 42 is provided on the left side inside the bottom shell 41, and a second transmission plate 43 is provided on the right side inside the bottom shell 41.

[0046] In some examples, the tops of the first transmission plate 42 and the second transmission plate 43 both extend into the interior of the first limiting groove 61, and the first transmission plate 42 and the second transmission plate 43 are respectively fixedly connected to the left and right sets of correction tables 31.

[0047] In some examples, two sets of gears 45 are rotatably mounted inside the bottom shell 41, two sets of racks 44 are fixedly mounted on the right side of the first transmission plate 42, and two sets of racks 44 are also fixedly mounted on the left side of the second transmission plate 43, with each pair of racks 44 meshing with the gears 45 respectively.

[0048] Both sets of racks 44 mesh with gears 45, causing the first transmission plate 42 and the second transmission plate 43 to move relative to each other synchronously, and further causing the two sets of straightening mechanisms 3 to move synchronously toward the center of the support platform 1, ensuring that the U-shaped steel 5 is located in the middle of the support platform 1.

[0049] In some examples, a second hydraulic cylinder 46 is fixedly installed on the outer wall of the bottom shell 41. The telescopic end of the second hydraulic cylinder 46 extends into the interior of the bottom shell 41 and is fixedly connected to the first transmission plate 42.

[0050] Then, the staff starts the second hydraulic cylinder 46 through the master control switch. The extension end of the second hydraulic cylinder 46 pushes the first transmission plate 42 to the right. As the first transmission plate 42 moves, the rack 44 drives the gear 45 to rotate. Furthermore, both sets of racks 44 mesh with the gear 45, causing the first transmission plate 42 and the second transmission plate 43 to move relative to each other, thus shortening the distance between the first transmission plate 42 and the second transmission plate 43. As the first transmission plate 42 and the second transmission plate 43 move, the distance between the two sets of straightening mechanisms 3 shortens, thus completing the positioning of the U-shaped steel 5 and the straightening mechanism 3.

[0051] In some examples, the top left and right sides of the control block 25 are provided with sloping surfaces 26, and the left and right sides of the control block 25 and the protective plate 21 abut against each other.

[0052] By setting two sets of slope surfaces 26, it is ensured that the control block 25 can gradually push the protective plate 21 to the left and right sides when it moves upward, so that it can adapt to most of the inner diameter of the U-shaped steel 5.

[0053] Working principle and usage process of this utility model:

[0054] When the U-shaped steel 5 needs to be straightened, the operator first powers on the device and then places the U-shaped steel 5 on the support platform 1. At this time, the operator should ensure that the groove of the U-shaped steel 5 is locked on the top of the two sets of protective plates 21. Then, the operator controls the operation of the first motor 23 through the main control switch. The operation of the first motor 23 drives the lead screw 24 to rotate. The rotation of the lead screw 24 drives the control block 25, which is threadedly connected to it, to move along the telescopic groove 63. When the control block 25 moves upward, the slope surface 26 on the left and right sides of the control block 25 will abut against the protective plates 21 and move the two sets of protective plates 21 to the left and right ends along the second limit groove 62 until the roller 22 and the inner wall of the U-shaped steel 5 abut against each other. Then the operator can stop the first motor 23. At this time, the roller 22 on the left and right sets of protective plates 21 abut against the inner wall of the U-shaped steel 5, providing internal support for the U-shaped steel 5.

[0055] Then, the staff starts the second hydraulic cylinder 46 through the master control switch. The extension end of the second hydraulic cylinder 46 pushes the first transmission plate 42 to the right. As the first transmission plate 42 moves, the rack 44 drives the gear 45 to rotate. Furthermore, both sets of racks 44 mesh with the gear 45, causing the first transmission plate 42 and the second transmission plate 43 to move relative to each other, thus shortening the distance between the first transmission plate 42 and the second transmission plate 43. As the first transmission plate 42 and the second transmission plate 43 move, the distance between the two sets of straightening mechanisms 3 shortens, thus completing the positioning of the U-shaped steel 5 and the straightening mechanism 3.

[0056] After the spacing between the two sets of straightening mechanisms 3 is adjusted, the pressure roller 35 and the outer wall of the U-shaped steel 5 come into contact with each other. The operator can start the first hydraulic cylinder 34. The telescopic end of the first hydraulic cylinder 34 will drive the straightening plate 33 to move along the movable groove 32. Further, the pressure roller 35 and the outer wall of the U-shaped steel 5 will abut against each other. The operator can control the straightening force of the pressure roller 35 on the U-shaped steel 5 through the first hydraulic cylinder 34. Finally, the operator starts the second motor 36. The operation of the second motor 36 will drive one set of synchronous pulleys 37 to rotate. However, the two sets of synchronous pulleys 37 are connected by a synchronous belt 38, so that the two sets of synchronous pulleys 37 rotate synchronously and drive the pressure roller 35 to rotate. As the pressure roller 35 rotates, the straightening mechanism 3 will straighten the U-shaped steel 5 and transport it at the same time.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
