Abstract
Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic bracket installation technology, specifically, it relates to a protective clamp for thread rolling of photovoltaic bracket tie rods. Background Technology
[0002] In photovoltaic (PV) support systems, to enhance the stability of the connection between the beams and columns and meet mechanical requirements such as wind and earthquake resistance, threaded tie rods are typically installed diagonally at the junction of the beams and columns. By engaging the threads at one or both ends of the tie rod with threaded holes or nuts pre-installed on the beams and columns, the beams and columns are tightly pulled together, improving the rigidity and stability of the overall structure. Furthermore, in adjustable-angle PV support systems, threaded tie rods are a key component for adjusting the angle of the PV panels. By installing threaded adjustment tie rods between the support system and the PV panel mounting frame, when it is necessary to adjust the tilt angle of the PV panels to adapt to different seasons or geographical locations with varying sunlight conditions, the tie rods can be rotated to extend or shorten under the action of the threads, thereby pushing or pulling the PV panel mounting frame and achieving precise adjustment of the PV panel angle.
[0003] Therefore, tie rods formed by threading one or both ends of a member are common components in photovoltaic support systems. Currently, for small-scale thread rolling of photovoltaic support tie rods, thread rolling machines are typically used. During the thread rolling process, operators need to manually support the workpiece to control its sway. This results in problems such as low stability of workpiece control, time-consuming and labor-intensive processes. At the same time, the workpiece may sway significantly due to localized bending, posing a safety hazard that could easily injure the operator. Utility Model Content
[0004] To solve or partially solve the problems existing in related technologies, this utility model provides a protective fixture for thread rolling of photovoltaic bracket tie rods. This protective fixture for thread rolling of photovoltaic bracket tie rods aims to solve the problems of low control stability of workpieces, time-consuming and labor-intensive, and easy to cause injury to operators when manually supporting workpieces for thread rolling in the prior art.
[0005] This application provides a protective clamp for thread rolling of photovoltaic bracket tie rods, including a hinge seat, hinge lug, pin, operating rod, and positioning sleeve;
[0006] The hinge seat is fixedly installed on the work platform, and the hinge ear is rotatably fixedly installed on the hinge seat through a pin. One end of the operating rod is fixedly installed on the hinge ear, and the other end is suspended in the air. The operating rod can rotate in the vertical plane with the axis of the pin as the center. The positioning sleeve is horizontally fixedly installed on the operating rod. The positioning sleeve is spaced apart from the two rotating rollers of the thread rolling machine, and the axis of the positioning sleeve is parallel to the axis of the two rotating rollers of the thread rolling machine. The workpiece to be threaded can be freely rotated and passed through the positioning sleeve.
[0007] In one alternative, a positioning block is fixedly installed on the work platform below the operating lever. The top of the positioning block has a positioning groove that matches the operating lever. When the operating lever rests on the positioning groove of the positioning block, the axis of the positioning sleeve and the two rotating rollers of the thread rolling machine are in the same horizontal plane, and the workpiece to be threaded is located between the two rotating rollers of the thread rolling machine.
[0008] In one alternative embodiment, the operating lever includes an inclined section and a horizontal section arranged at an angle, the inclined section and the horizontal section being connected end to end, and a positioning sleeve being symmetrically fixed on the horizontal section, with the positioning sleeve being perpendicular to the horizontal section.
[0009] When the tilting section of the operating lever rests against the positioning groove of the positioning block, the horizontal section is parallel to the plane of the working platform.
[0010] In one alternative, a fixed ball is fixedly mounted at the end of the tilt section of the control lever away from the horizontal section.
[0011] In one alternative embodiment, the hinge includes a base plate, a first ear plate, and a second ear plate. The base plate is fixedly mounted on a work platform, and the first ear plate and the second ear plate are vertically fixedly mounted on the top of the base plate at intervals. The distance between the first ear plate and the second ear plate matches the thickness of the hinge lug.
[0012] The beneficial effects of this utility model are:
[0013] This utility model uses a positioning sleeve to support the workpiece and an operating rod to control the workpiece's swing. This replaces the existing technology where the operator directly supports the workpiece and controls its swing by hand.

[0028] In the existing technology, the thread rolling of photovoltaic bracket tie rods requires the operator to manually support the workpiece on the thread rolling machine to control its swing. This has problems such as low control stability of the workpiece, time and labor, and safety hazards that may cause injury to the operator.
[0029] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.
[0030] In some implementations, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A protective fixture for thread rolling of photovoltaic bracket tie rods is provided, including a hinge seat 1, a hinge lug 2, a pin 3, an operating rod 4, and a positioning sleeve 5. The hinge seat 1 is fixedly installed on a work platform 10. The hinge lug 2 is rotatably fixedly installed on the hinge seat 1 via the pin 3. One end of the operating rod 4 is fixedly installed on the hinge lug 2, and the other end is suspended. The operating rod 4 can rotate in a vertical plane with the axis of the pin 3 as the center. The positioning sleeve 5 is horizontally fixedly installed on the operating rod 4. The positioning sleeve 5 is spaced apart from the two rotating rollers 20 of the thread rolling machine, and the axis of the positioning sleeve 5 is parallel to the axis of the two rotating rollers 20 of the thread rolling machine. The workpiece 30 to be threaded can be freely rotatably inserted into the positioning sleeve 5. Specifically, in this embodiment, the hinge seat 1 and the hinge lug 2 are both steel plates with a diameter of t = 6 mm, the pin 3 is a round steel bar with a diameter of 12 mm, the operating rod 4 is a round steel bar with a diameter of 14 mm, and the positioning sleeve 5 is a steel pipe with a diameter of 18 × 2 mm.
[0031] Therefore, when it is necessary to perform thread rolling on the photovoltaic bracket tie rod, such as Figure 1 , Figure 2 As shown, the workpiece 30 to be threaded is placed in the positioning sleeve 5, and the operating lever 4 is flipped downwards so that the operating lever 4 drives the workpiece 30 to the space between the two rotating rollers 20 of the thread rolling machine through the positioning sleeve 5. The length of the end of the workpiece 30 extending between the two rotating rollers 20 of the thread rolling machine is adjusted according to the required thread rolling length. Then the thread rolling machine is started so that the two rotating rollers 20 of the thread rolling machine gradually come together to complete the thread rolling of the workpiece 30.
[0032] This protective clamp supports the workpiece 30 through the positioning sleeve 5. During the thread rolling process, the workpiece 30 can rotate freely within the positioning sleeve 5 to ensure the normal completion of the thread rolling. The swing of the workpiece 30 is controlled by the operating rod 4. Thus, the positioning sleeve 5 and the operating rod 4 replace the existing technology where the operator directly supports the workpiece 30 and controls its swing by hand. The control stability of the workpiece 30 is high, the operation is time-saving and labor-saving, safe and reliable, and effectively eliminates the safety hazard of the operator being injured by the large swing of the workpiece 30. Moreover, it has a simple structure, is easy to operate and install.
[0033] In some implementations, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6A positioning block 6 is fixedly installed on the working platform 10 below the operating lever 4. The top of the positioning block 6 is constructed with a positioning groove 601 that matches the operating lever 4, so as to position the flip position of the operating lever 4 through the positioning block 6 and the positioning groove 601. Specifically, when the operating lever 4 rests on the positioning groove 601 of the positioning block 6, the axis of the positioning sleeve 5 and the two rotating rollers 20 of the thread rolling machine are in the same horizontal plane, and the workpiece 30 to be threaded is located between the two rotating rollers 20 of the thread rolling machine. In this way, it can be ensured that each workpiece 30 is in the optimal thread rolling position when performing thread rolling processing, thereby effectively improving the thread rolling processing quality of the workpiece 30 and effectively improving the consistency of the finished photovoltaic bracket tie rod.
[0034] In some embodiments, the operating lever 4 includes an inclined section 401 and a horizontal section 402 arranged at an angle, with the inclined section 401 and the horizontal section 402 connected end to end. A positioning sleeve 5 is symmetrically fixedly installed on the horizontal section 402, and the positioning sleeve 5 is perpendicular to the horizontal section 402. When the inclined section 401 of the operating lever 4 rests against the positioning groove 601 of the positioning block 6, the horizontal section 402 is parallel to the plane of the work platform 10. This improves the ease and comfort of operating the operating lever 4, and also enhances the stability of the operating lever 4 and the positioning sleeve 5 in supporting the workpiece 30 during thread rolling.
[0035] In some embodiments, a retaining ball 7 is fixedly installed at the end of the inclined section 401 of the operating lever 4 away from the horizontal section 402. In this way, the retaining ball 7 can shield the end of the operating lever 4, which can effectively prevent the edge of the end of the operating lever 4 from scratching the operator, and at the same time improve the comfort of the operator in operating and holding the operating lever 4.
[0036] In some embodiments, the hinge 1 includes a base plate 101, a first ear plate 102, and a second ear plate 103. The base plate 101 is fixedly mounted on the work platform 10. The first ear plate 102 and the second ear plate 103 are vertically fixedly mounted on the top of the base plate 101 at intervals. The distance between the first ear plate 102 and the second ear plate 103 matches the thickness of the hinge ear 2. This facilitates the secure mounting of the hinge 1 onto the work platform 10 via the base plate 101, thereby improving the stability of the operating rod 4 and the positioning sleeve 5 in supporting the workpiece 30 during thread rolling. At the same time, through the cooperation of the hinge ear 2 with the first ear plate 102, the second ear plate 103, and the pin 3, it is ensured that the operating rod 4 can only rotate in a vertical plane with the axis of the pin 3 as the center. This effectively prevents the operating rod 4 and the positioning sleeve 5 from deflecting, which is beneficial to ensuring the quality of thread rolling of the workpiece 30.
[0037] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
