Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket clamp testing technology, and in particular to a photovoltaic bracket clamp pull-out device for color steel tile bearing capacity. Background Technology

[0002] When installing photovoltaic brackets on corrugated steel tile roofs, "load-bearing capacity" is a core safety indicator, directly related to the stability of the photovoltaic system and the durability of the corrugated steel tile structure. The corrugated steel tile load-bearing photovoltaic bracket clamp pull-out device is a test equipment specifically designed for corrugated steel tile roof photovoltaic systems. It is used to simulate the pull-out load-bearing capacity of the photovoltaic bracket clamps under actual working conditions (such as being subjected to wind suction and the self-weight of the components).

[0003] In existing technologies, the main body of the device is constructed using aluminum alloy profiles (such as the 4080 series), with the weight controlled to within 50kg to avoid damaging the corrugated steel tile specimens. Rubber pads are added to the bottom of the frame to enhance friction with the ground. The core objective is to verify the reliability of the connection between the clamp and the corrugated steel tile, while avoiding excessive damage to the corrugated steel tile itself during the test (ensuring that the test results reflect the "clamp-corrugated steel tile connection strength" rather than the "corrugated steel tile's own strength"). However, temperature changes can affect the performance of the clamp material (such as the thermal expansion and contraction of aluminum alloy), and humidity may cause the adhesive clamp to fail. Currently, shape memory alloy clamps are being explored, which achieve adaptive fastening through temperature-triggered deformation and maintain a constant preload within the range of -20℃ to 60℃. However, this method lacks versatility. When changing specimens of different specifications, the clamping structure needs to be significantly adjusted (such as disassembling and welding the fixtures), which is cumbersome and prone to introducing test deviations due to adjustment errors. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a photovoltaic bracket clamping pull-out device for color steel tile bearing capacity, which aims to improve the lack of versatility in the existing technology. When changing test pieces of different specifications, it is necessary to make significant adjustments to the clamping structure (such as disassembling and welding the fixtures), which is cumbersome and prone to introducing test deviations due to adjustment errors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic bracket clamping and pulling device for color steel tile bearing capacity, comprising a machine body, a fixed frame fixedly connected to the top wall of the machine body, a fixed plate fixedly connected to the middle of the inner wall of the machine body, clamping mechanisms installed in the middle of the inner top wall of the fixed frame and the middle of the top wall of the fixed plate, the clamping mechanisms being used to clamp clamps of different specifications, and multiple fixed mechanisms equidistantly installed on the left and right sides of the top wall of the machine body, the fixed mechanisms being used to fix the fixed frame; the clamping mechanism includes a hydraulic rod one, the hydraulic rod one being fixedly connected to the middle of the inner top wall of the fixed frame, a housing fixedly connected to the bottom end of the hydraulic rod one, a rotating shaft two being rotatably connected to the middle of the front side of the outer wall of the housing, a rotating shaft three being rotatably connected to the lower middle of the front side of the outer wall of the housing, multiple connecting rods three being rotatably connected equidistantly to the outer wall of the rotating shaft three, and a driving assembly installed on the inner wall of the housing.

[0006] As a further description of the above technical solution: The drive assembly includes a hydraulic rod 2. A rotating shaft 1 is installed at the top of the housing. The rotating shaft 1 is slidably connected to the front side of the outer wall of the housing. A plurality of connecting rods 1 are equidistantly rotatably connected to the outer wall of the rotating shaft 1. A connecting rod 2 is rotatably connected to the end of the connecting rod 1. The connecting rod 2 is rotatably connected to the outer wall of the rotating shaft 2.

[0007] As a further description of the above technical solution: A fixed rod is rotatably connected to the outer wall of the connecting rod three. The upper middle part of the outer wall of the fixed rod is connected to the connecting rod two. An anti-slip block is fixedly connected to the lower middle part of the inner side of the fixed rod.

[0008] As a further description of the above technical solution: The fixing mechanism includes a base, which is equidistantly fixed to the left and right sides of the top wall of the machine body. Multiple protrusions are equidistantly fixed to the inner side of the base, and the protrusions are slidably connected to the outer wall of the fixing frame. A transmission component is installed on the right side of the top wall of the base.

[0009] As a further description of the above technical solution: The transmission assembly includes a fixing block, which is fixedly connected to the right side of the top wall of the base, and a threaded rod is threadedly connected to the inner wall of the fixing block.

[0010] As a further description of the above technical solution: The outer wall of the threaded rod is rotatably connected to a connecting block, the connecting block is slidably connected to the top wall of the base, and multiple locking blocks are equidistantly fixed to the outer wall of the connecting block, the locking blocks being slidably connected to the inner wall of the fixing frame.

[0012] As a further description of the above technical solution: The controller is equipped with a display screen on its top, which is fixedly connected to the right side of the top wall of the controller.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after the hydraulic rod 2 is started, it drives the rotating shaft 1 to slide up and down inside the outer shell. When the rotating shaft 1 moves, it pulls the connecting rod 1, which in turn pulls the connecting rod 2, causing the connecting rod 2 to rotate along the rotating shaft 2. The connecting rod 2 then pulls the fixed rod, which in turn drives the connecting rod 3, causing the connecting rod 3 to rotate along the rotating shaft 3. This drives the fixed rod and the anti-slip block to move, enabling opening and closing actions to clamp the fixture. It can adapt to fixtures of different sizes, and when changing fixtures of different specifications, there is no need to make significant adjustments to the clamping structure, such as disassembling and welding the tooling.

[0014] 2. In this utility model, when installing the fixing frame, slide the fixing frame down along the protrusion and close to the outside of the base. Then rotate the threaded rod inside the fixing block. The threaded rod rotates and drives the connecting block on the outer wall, thereby pushing the connecting block to slide into the fixing frame inside the base and causing the locking block to insert into the inner wall of the fixing frame, forming a stable connection and preventing the fixing frame from loosening when subjected to large tensile force.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a photovoltaic bracket clamping device for color steel tile bearing capacity, comprising a body 1, a fixed frame 2 fixedly connected to the top wall of the body 1, a fixed plate 5 fixedly connected to the middle of the inner wall of the body 1, clamping mechanisms 3 installed in the middle of the inner top wall of the fixed frame 2 and the middle of the top wall of the fixed plate 5, the clamping mechanisms 3 being used to clamp clamps of different specifications, and multiple fixing mechanisms 4 equidistantly installed on the left and right sides of the top wall of the body 1, the fixing mechanisms 4 being used to fix the fixed frame 2; the clamping mechanism 3 includes a hydraulic rod 301, the hydraulic rod 301 being fixedly connected to the middle of the inner top wall of the fixed frame 2, the bottom end of the hydraulic rod 301 being fixedly connected to a housing 302, the middle of the front side of the outer wall of the housing 302 being rotatably connected to a rotating shaft 308, and the lower middle of the front side of the outer wall of the housing 302 being rotatably connected to... A rotating shaft 309 is connected to the outer wall of the rotating shaft 309, and multiple connecting rods 305 are rotatably connected at equal intervals. A drive assembly 303 is installed on the inner wall of the outer shell 302. The drive assembly 303 includes a hydraulic rod 3032. A rotating shaft 3031 is installed at the top of the outer shell 302. The rotating shaft 3031 is slidably connected to the front side of the outer wall of the outer shell 302. Multiple connecting rods 3033 are rotatably connected to the outer wall of the rotating shaft 3031 at equal intervals. A connecting rod 304 is rotatably connected to the end of the connecting rod 3033. The connecting rod 304 is rotatably connected to the outer wall of the rotating shaft 308. A fixing rod 306 is rotatably connected to the outer wall of the connecting rod 305. The upper middle part of the outer wall of the fixing rod 306 is connected to the connecting rod 304. An anti-slip block 307 is fixedly connected to the lower middle part of the inner side of the fixing rod 306. Specifically, when hydraulic rod 2 3032 is activated, it drives rotating shaft 1 3031 to slide up and down within housing 302. During this movement, rotating shaft 1 3031 pulls connected connecting rod 1 3033, which in turn pulls connecting rod 2 304, causing it to rotate along rotating shaft 2 308. As connecting rod 2 304 rotates, it further pulls fixed rod 306. Fixed rod 306, through transmission connecting rod 305, causes connecting rod 305 to rotate along rotating shaft 309. Ultimately, this allows fixed rod 306 and anti-slip block 307 to open and close, thus achieving the clamping function of the fixture. Once the fixture is fixed, hydraulic rod 1 301 is activated simultaneously, and both hydraulic rods... Pulling the outer casing 302 with hydraulic rod 301 performs a pull-out test on the fixture held by the anti-slip block 307. The anti-slip block 307 prevents the fixture from slipping during the pull-out process, thus avoiding test interruption and sudden drop in force, ensuring that the ultimate strength of the fixture can be measured. Hydraulic rod 301 and hydraulic rod 3032 are hydraulic devices composed of piston rods and cylinders, which are medium-pressure cylinders: 16-25MPa (general industrial equipment). The pressure is directly marked, such as CD250B-100 / 50-500 (25MPa). In addition, this mechanism can adapt to fixtures of different sizes. When changing fixtures of different specifications, there is no need to make major adjustments to the clamping structure, such as disassembling and welding the tooling, thereby greatly improving the convenience and efficiency of operation.

[0019] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 4 includes a base 403, which is equidistantly fixed to the left and right sides of the top wall of the body 1. Multiple protrusions 401 are equidistantly fixed to the inner side of the base 403. The protrusions 401 are slidably connected to the outer wall of the fixing frame 2. A transmission assembly 404 is installed on the right side of the top wall of the base 403. The transmission assembly 404 includes a fixing block 4041, which is fixedly fixed to the right side of the top wall of the base 403. A threaded rod 4042 is threadedly connected to the inner wall of the fixing block 4041. A connecting block 402 is rotatably connected to the outer wall of the threaded rod 4042. The connecting block 402 is slidably connected to the top wall of the base 403. Multiple locking blocks 405 are equidistantly fixed to the outer wall of the connecting block 402. The locking blocks 405 are slidably connected to the inner wall of the fixing frame 2. Specifically, during the installation of the mounting bracket 2, the mounting bracket 2 first needs to be slid downwards along the protrusion 401 to ensure that it is tightly attached to the outer side of the base 403. Next, the threaded rod 4042 inside the mounting block 4041 needs to be rotated. As the threaded rod 4042 rotates, it will drive the connecting block 402 on the outer wall, causing the connecting block 402 to slide towards the mounting bracket 2 within the base 403. This ensures that the connecting block 402 can move smoothly within the base 403. Finally, the locking block 405 will be inserted into the inner wall of the mounting bracket 2, thereby forming a stable connection. This stable connection method can effectively prevent the mounting bracket 2 from loosening when subjected to large tensile forces, ensuring the stability and safety of the overall structure.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the machine body 1 is equipped with a controller 7, which is fixedly connected to the right side of the outer wall of the machine body 1. The controller 7 is a Siemens S7-1214CDC / DC / DC model PLC (Programmable Logic Controller). This model is equipped with 14 inputs (DC24V) and 10 outputs (DC24V), supports a maximum user program storage capacity of 16kB, and has a processing speed of 0.15μs / instruction. The top of the controller 7 is equipped with a display screen 6, which is fixedly connected to the right side of the top wall of the controller 7. The display screen 6 is a Weintek MT8102iE model industrial touch screen with a screen size of 10.1 inches, a resolution of 1024×600, and has wide temperature (-10℃~60℃) operating capability and anti-electromagnetic interference characteristics. Specifically, the controller 7 can efficiently respond to various signals during equipment operation, perform logical operations and data processing through built-in programs, and the display screen 6 serves as a human-machine interface, displaying key parameters in real time during the testing process. Operators can set parameters through the touch screen, and the screen will also provide real-time prompts for equipment fault information, facilitating quick troubleshooting and significantly improving operational convenience and testing efficiency.

[0021] Working principle: After hydraulic rod 2 3032 is started, it drives rotating shaft 1 3031 to slide up and down inside housing 302. When rotating shaft 1 3031 moves, it pulls connecting rod 1 3033. Connecting rod 1 3033 then pulls connecting rod 2 304, causing connecting rod 2 304 to rotate along rotating shaft 2 308. Connecting rod 2 304 then pulls fixed rod 306. Fixed rod 306 drives connecting rod 3 305, causing connecting rod 3 305 to rotate along rotating shaft 3 309, thereby driving fixed rod 306 and anti-slip block 307. The device is movable and can open and close to clamp the fixture. After the fixture is fixed, hydraulic rod 301 is activated simultaneously. The two hydraulic rods 301 pull the outer shell 302 to perform a pull-out test on the fixture held by the anti-slip block 307. The anti-slip block 307 can prevent the fixture from slipping during the pull-out process, which would cause the test to be interrupted and the force value to drop suddenly, making it impossible to measure the ultimate strength. It can adapt to fixtures of different sizes, and when changing to different specifications of fixtures, there is no need to make major adjustments to the clamping structure (such as disassembling and welding the tooling). When installing the mounting bracket 2, slide the mounting bracket 2 downward along the protrusion 401 and press it against the outside of the base 403. Then rotate the threaded rod 4042 inside the mounting block 4041. The threaded rod 4042 rotates and drives the connecting block 402 on the outer wall, thereby pushing the connecting block 402 to slide into the mounting bracket 2 inside the base 403 and causing the locking block 405 to be inserted into the inner wall of the mounting bracket 2, forming a stable connection and preventing the mounting bracket 2 from loosening when subjected to large tensile forces.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
