Description

Technical Field

[0001] This utility model relates to the field of wind power construction technology, and in particular to a test platform for testing the compressive bearing capacity of wind power. Background Technology

[0002] In the field of wind power equipment research and development and testing, compressive bearing capacity testing is an important step in ensuring the structural safety and stable performance of wind power equipment. Traditional wind power test platforms usually require placing wind power-related equipment (such as wind turbine components) on the platform and applying pressure through specific loading devices to simulate the stress conditions of the actual working environment when conducting compressive bearing capacity tests. However, existing wind power test platforms for compressive bearing capacity testing have some shortcomings in design and function.

[0003] Specifically, existing testing platforms often cannot automatically remove wind power-related equipment that has undergone compressive strength testing after the test is completed. This deficiency is mainly reflected in the following aspects: First, manual operation is cumbersome. After the test, operators need to manually disassemble and remove the test equipment, which not only increases the workload but may also lead to safety risks during the operation. Second, it is inefficient. The process of manually disassembling the equipment takes a certain amount of time, which reduces the efficiency and speed of the entire testing process and is not conducive to quickly obtaining test results and conducting subsequent analysis.

[0004] Therefore, there is an urgent need to provide a test platform for testing the compressive bearing capacity of wind power to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a test platform for testing the compressive bearing capacity of wind power.

[0006] To solve the above technical problems, the present invention adopts a technical solution as follows: a test platform for testing the compressive bearing capacity of wind power test equipment is provided, including a base, a load-bearing plate on the top of the base is slidably connected to the top of the base, a sliding shaft is rotatably connected to one side of the load-bearing plate, support rods are fixedly connected to the four corners of the top of the base, and a lower pressure plate is slidably connected to the outside of the multiple support rods, and a pushing mechanism is rotatably connected to the front and rear ends of the lower pressure plate.

[0007] The sliding shaft is fixedly connected to sliding mechanisms at both ends, a limit mechanism is slidably connected to the top of the base, and a reset mechanism is fixedly connected to the outward end of the sliding shaft.

[0008] The present invention is further configured such that: an operating platform is installed on the top of each of the multiple support rods; an electric push rod is installed at the bottom of the operating platform, one end of which is fixedly connected to the top of the lower pressure plate; two fixing blocks for placing wind power related equipment are fixedly connected to the top of the load-bearing plate; guide blocks located at the front and rear ends of the load-bearing plate are fixedly connected to the top of the base; and a slot 2 is opened on one side of the base.

[0009] Through the above technical solution, the operating platform is designed to facilitate personnel operation and data collection, allowing for intuitive observation of the test content. The platform allows operators to control electric push rods, which in turn drive the pressure plate to press down on the wind turbine under test. Fixed blocks ensure that the equipment is securely placed on the load-bearing plate. The load-bearing plate not only bears the weight of the equipment under test but also transmits data back to the operating platform via integrated pressure sensors. Furthermore, guide blocks limit and guide the sliding of the load-bearing plate, while the second slot allows the load-bearing plate to tilt slightly after sliding to a specific position. This design cleverly utilizes the weight of the wind turbine, enabling the tested equipment to slide smoothly down, achieving automatic unloading—a quick and practical solution.

[0010] The present invention is further configured such that: the pushing mechanism includes two rods rotatably connected to the bottom of the lower pressure plate, and each of the two rods is provided with a shaft 2 at its other end. The shaft 2 can both rotate and slide axially inside the rods 2. The two shafts 2 are fixedly connected to a shaft 3 at their inward ends. The top of the base is fixedly connected to multiple guide rails. The two shafts 3 are respectively located in the multiple guide rails. The top of each of the two shafts 3 is rotatably connected to a cap. The two caps are respectively located above the two guide rails.

[0011] Through the above technical solution, the driving mechanism is responsible for driving the load-bearing plate to slide; when the pressure plate performs the pressing action, the second rod deflects and moves accordingly, with one end moving towards the second block; this movement drives the movement of the second shaft, which in turn causes the third shaft to move smoothly inside the guide rail; the cap design ensures that the third shaft is stable inside the guide rail and always remains vertical. This mechanism is convenient and quick, simple in design and practical and efficient.

[0012] The present invention is further configured such that: the sliding mechanism includes two blocks 2 fixedly connected to the front and rear ends of the sliding shaft respectively; a shaft 4 is fixedly connected inside each of the two blocks 2; a block 3 is rotatably connected to the outside of each of the two shafts 4; a torsion spring is sleeved on the outside of each of the two shafts 4; the two ends of the torsion spring are fixedly connected to the shaft 4 and the block 3 respectively; and a block 4 is fixedly connected to the inward side of each of the two blocks 2.

[0013] Through the above technical solution, the sliding mechanism is designed to allow the load-bearing plate to slide smoothly on the base. When the pressure plate is pressed down, it drives rod two to deflect, and one end of rod two moves towards block two. This action in turn drives shaft two and shaft three to slide within the guide rail. Shaft three continues to slide until it contacts block three and deflects it, during which the torsion spring is compressed. Afterward, shaft three continues to move in the same direction until it separates from block three. At this time, the torsion spring releases its elastic force, causing block three to automatically return to its initial position. Block three is always located on the movement path of shaft three. The pressing action of the pressure plate actually applies pressure to the wind turbine mechanism to conduct a load-bearing capacity test. After the test is completed, the pressure plate moves up, causing rod two to deflect in the opposite direction, which in turn causes shaft three to slide in the opposite direction within the guide rail. During the operation, it will contact block three again, but at this time block four is in front of block three, preventing further deflection of block three and causing block four, block two, and the sliding shaft to move, ultimately driving the load-bearing plate and the wind power equipment on it to move together; when the load-bearing plate moves to the position of slot two, it will automatically tilt due to the design. At the same time, under the action of the wind power equipment's own weight, the equipment will slide off the load-bearing plate, completing the automatic unloading process; on the other hand, after the load-bearing plate completes the unloading, shaft three continues to move along the guide rail until it enters the curved section of the guide rail and disengages from block three; at this time, under the action of the tension spring, the load-bearing plate automatically returns to the initial state, and rod two and the lower pressure plate also return to the starting position, ready to receive the next operation; this mechanism is convenient, fast, simple and practical.

[0014] The present invention is further configured such that: the limiting mechanism includes two T-shaped blocks respectively fixedly connected to the bottom of the two blocks 2, and the top of the base is provided with grooves 3 respectively corresponding to the two T-shaped blocks.

[0015] Through the above technical solution, the function of the limiting mechanism is to provide precise limiting and guidance for block two. It uses the close cooperation between the T-block and the slot three to ensure that block two can only move along the preset path. This design further enables block three, block four and sliding shaft to follow the predetermined trajectory. The whole system is easy to operate and highly practical.

[0016] The present invention is further configured such that: the reset mechanism includes two shafts five fixedly connected to the outward side of the front and rear ends of the sliding shaft respectively; two first brackets are fixedly connected to one side of the base; each of the two first brackets has a cylinder two that is slidably connected to the two shafts five respectively; and tension springs are sleeved on the outside of the two cylinders two respectively; the two ends of the tension springs are fixedly connected to the cylinder two and the shaft five respectively.

[0017] Through the above technical solution, the design of the reset mechanism aims to ensure that the load-bearing plate can automatically and smoothly reset after the separation of block three and shaft three. The entire mechanism operates as follows: rod two drives shaft three to move, shaft three in turn pushes block three, and the movement of block three drives the displacement of the sliding shaft and the load-bearing plate. This series of actions simultaneously causes shaft five to slide inside cylinder two. During this process, the tension spring is stretched and stores elastic potential energy. During the movement of shaft three, it always moves in close contact with block three. However, when shaft three travels to the curved area of ​​the guide rail, under the precise guidance of the guide rail, shaft three and block three achieve smooth separation. At this time, the tension spring, with its stored elastic force, quickly pulls shaft five back to the starting position inside cylinder two. The reset action of shaft five leads to the reset of the sliding shaft and the load-bearing plate. This automatic reset mechanism is not only easy to operate and highly practical, but also efficient and fast, fully demonstrating the ingenuity and optimization of the design.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses an electric push rod to drive the lower pressure plate, enabling rapid and accurate testing of the compressive strength of wind power equipment. The testing process is highly automated, reducing manual intervention and improving testing efficiency. After the test, the load-bearing plate automatically tilts, using the weight of the wind power equipment for automatic unloading, avoiding the tedious manual handling and saving time and labor costs. Through the cooperation of tension springs and guide rails, the load-bearing plate can automatically return to its initial position after unloading, requiring no additional operation, simplifying the testing process and improving the continuous operation capability of the equipment.

[0020] 2. This utility model ensures the stability of the shaft during movement through the cooperation of the guide rail, cap, and shaft three, avoiding errors caused by equipment shaking or offset during testing and guaranteeing the accuracy of test results. The operating platform integrates control and data collection functions, allowing testers to intuitively observe the test process and data, facilitating real-time adjustments and recording, and improving the controllability and operability of the test. Through the ingenious use of elastic elements such as torsion springs and tension springs, the smooth movement and reset of the load-bearing plate are achieved. The overall structure is simple and practical, and easy to maintain and operate. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] Please see Figures 1-5 This embodiment describes a test platform for testing the compressive bearing capacity of wind power equipment. It includes a base 1, a load-bearing plate 2 slidably connected to the top of the base 1, on which wind power-related equipment is placed. A sliding shaft 3 is rotatably connected to one side of the load-bearing plate 2. Support rods 4 are fixedly connected to the four corners of the top of the base 1. A lower pressure plate 5 is slidably connected to the outside of each support rod 4. A pushing mechanism 6 is rotatably connected to both the front and rear ends of the lower pressure plate 5. The pushing mechanism 6 includes two rods 601 rotatably connected to the bottom of the lower pressure plate 5. A shaft 602 is provided at the other end of each rod 601. The shaft 602 can both rotate and slide axially within the rods 601. A shaft 603 is fixedly connected to the inward-facing end of each shaft 602. Multiple guide rails 604 are fixedly connected to the top of the load-bearing plate 2. Two shafts 603 are located within the multiple guide rails 604. The top of each shaft 603 is rotatably connected to a cap 605. The two caps 605 are located above the two guide rails 604. The pushing mechanism 6 is responsible for driving the load-bearing plate 2 to slide. When the pressing plate 5 performs the pressing action, the rod 601 deflects and moves accordingly, with one end moving towards the block 701. This movement drives the movement of shaft 602, which in turn causes shaft 603 to move smoothly within the guide rails 604. The design of the caps 605 ensures that shaft 603 is stable within the guide rails 604 and always remains vertical. This mechanism is convenient, quick, simple in design, and practical and efficient.

[0029] like Figures 4-5As shown, sliding mechanisms 7 are fixedly connected to both the front and rear ends of the sliding shaft 3. Each sliding mechanism 7 includes two blocks 701 fixedly connected to the front and rear ends of the sliding shaft 3. A shaft 702 is fixedly connected inside each block 701. A block 703 is rotatably connected to the outside of each shaft 702. A torsion spring 704 is sleeved on the outside of each shaft 702, with both ends of the torsion spring 704 fixedly connected to the shaft 702 and the block 703, respectively. A block 705 is fixedly connected to the inward-facing side of each block 701. The sliding mechanism 7 is designed to allow the load-bearing plate 2 to rest on the base 1. The upper part slides smoothly; when the lower pressure plate 5 presses down, it drives the second rod 601 to deflect, and one end of the second rod 601 moves towards the second block 701. This action drives the second shaft 602 and the third shaft 603 to slide within the guide rail 604; the third shaft 603 continues to slide until it contacts the third block 703 and deflects it, during which the torsion spring 704 is compressed; then, the third shaft 603 continues to move in the same direction until it separates from the third block 703. At this time, the torsion spring 704 releases its elastic force, causing the third block 703 to automatically return to its initial position; the third block 703 is always located in the movement path of the third shaft 603. The downward pressing action of the lower pressure plate 5 actually applies pressure to the wind turbine mechanism to conduct a load-bearing capacity test. After the test is completed, the lower pressure plate 5 moves upward, causing rod 2 601 to deflect in the opposite direction, which in turn causes shaft 3 603 to slide in the opposite direction within the guide rail 604. During the sliding process of shaft 3 603, it will contact block 3 703 again, but at this time block 4 705 is already in front of block 3 703, preventing further deflection of block 3 703, and causing block 4 705, block 2 701 and sliding shaft 3 to move, ultimately driving the load-bearing plate 2 and the wind turbine equipment on it to move together. When the load-bearing capacity is increased, the wind turbine equipment on the load-bearing plate 2 will move together with the wind turbine equipment on the load-bearing plate 2. When plate 2 moves to position 14 of slot 2, it will automatically tilt due to its design. At the same time, under the weight of the wind power equipment, the equipment will slide off the load-bearing plate 2, completing the automatic unloading process. On the other hand, after the load-bearing plate 2 has completed unloading, shaft 3 603 continues to move along guide rail 604 until it enters the curved section of guide rail 604 and disengages from block 3 703. At this time, under the action of tension spring 904, load-bearing plate 2 automatically returns to its initial state, and rod 2 601 and lower pressure plate 5 also return to their starting positions, ready to receive the next operation. This mechanism is convenient, fast, simple and practical.

[0030] like Figures 4-5 As shown, a limiting mechanism 8 is slidably connected to the top of the base 1. The limiting mechanism 8 includes two T-shaped blocks 801 that are fixedly connected to the bottom of the two blocks 701 respectively. The top of the base 1 is provided with a groove 802 that corresponds to the two T-shaped blocks 801 respectively. The function of the limiting mechanism 8 is to provide precise limiting and guidance for the blocks 701. It uses the tight cooperation between the T-shaped blocks 801 and the groove 802 to ensure that the blocks 701 can only move along the preset path. This design further enables the blocks 703, 705 and the sliding shaft 3 to move along the predetermined trajectory. The whole system is easy to operate and highly practical.

[0031] like Figures 4-5 As shown, a reset mechanism 9 is fixedly connected to the outward end of the sliding shaft 3. The reset mechanism 9 includes two shafts 901 fixedly connected to the outward sides of the front and rear ends of the sliding shaft 3, respectively. Two first supports 902 are fixedly connected to one side of the base 1. Each of the two first supports 902 has a cylinder 903 fixedly connected to the two shafts 901, respectively. Each cylinder 903 is fitted with a tension spring 904, and the two ends of the tension spring 904 are fixedly connected to the cylinder 903 and the shaft 901, respectively. The reset mechanism 9 is designed to ensure that the load-bearing plate 2 can automatically and smoothly reset after the block 703 and the shaft 603 are separated. The entire mechanism operates as follows: the second rod 601 drives the shaft 603 to move, the shaft 603 then pushes the block 703, and the movement of the block 703 in turn drives... The displacement of sliding shaft 3 and load-bearing plate 2 causes shaft 5 901 to slide inside cylinder 2 903. During this process, tension spring 904 is stretched and stores elastic potential energy. During the movement of shaft 3 603, it always moves in close contact with block 3 703. However, when shaft 3 603 moves to the bending area of ​​guide rail 604, shaft 3 603 and block 3 703 are smoothly separated under the precise guidance of guide rail 604. At this time, tension spring 904, with its stored elastic force, quickly pulls shaft 5 901 back to the starting position inside cylinder 2 903. The reset action of shaft 5 901 leads to the reset of sliding shaft 3 and load-bearing plate 2. This automatic reset mechanism is not only easy to operate and highly practical, but also efficient and fast, fully demonstrating the ingenuity and optimization of the design.

[0032] like Figures 1-2 As shown, an operating platform 10 is installed on the top of each of the multiple support rods 4. An electric push rod 11, one end of which is fixedly connected to the top of the lower pressure plate 5, is installed on the bottom of the operating platform 10. Two fixing blocks 12 for placing wind power-related equipment are fixedly connected to the top of the load-bearing plate 2. Guide blocks 13, located at the front and rear ends of the load-bearing plate 2, are fixedly connected to the top of the base 1. A slot 14 is provided on one side of the base 1. The operating platform 10 is designed to facilitate personnel operation and data collection, allowing for direct observation of the test results. Through this operating platform 10, the operator can control the electric push rod 11, thereby driving... The pressure plate 5 presses down on the wind turbine equipment to be tested; the fixing block 12 ensures that the equipment can be stably placed on the load-bearing plate 2; the load-bearing plate 2 not only bears the weight of the equipment to be tested, but also transmits data back to the operating platform 10 through an integrated pressure sensor; in addition, the guide block 13 plays a role in limiting and guiding the load-bearing plate 2 when it slides, and the setting of the slot 2 14 allows the load-bearing plate 2 to tilt slightly after sliding to a specific position; this design cleverly utilizes the self-weight of the wind turbine equipment, so that the wind turbine equipment after testing can slide smoothly down, realizing the function of automatic unloading, which is both fast and practical.

[0033] In use, the wind turbine is first placed on the load-bearing plate 2 and secured by the fixing block 12. The electric push rod 11 on the operating platform 10 is activated, driving the lower pressure plate 5 downwards. The lower pressure plate 5 presses down on the wind turbine on the load-bearing plate 2 to conduct a pressure test. The descent of the lower pressure plate 5 causes the connected rod 601 to deflect, thereby pushing shafts 602 and 603 to slide within the guide rail 604. The movement of shaft 603 causes it to contact block 703 and pushes block 703 to deflect, compressing the torsion spring 704. As shaft 603 continues to move, block 703 returns to its original position under the action of the torsion spring 704. After the test is completed, the electric push rod 11 rises, causing the lower pressure plate 5 to move upwards, and rod 601 to deflect in the opposite direction, while shaft 603... The shaft slides in the reverse direction within the guide rail 604; shaft 3 603 contacts block 3 703 again, but due to the obstruction of block 4 705, block 3 703 cannot continue to deflect, thus pushing the sliding shaft 3 and the load-bearing plate 2 to move, at which point the tension spring 904 is pulled; when the load-bearing plate 2 slides to the position of slot 2 14, the load-bearing plate 2 tilts, and the wind turbine automatically slides down under its own weight, completing the unloading; subsequently, shaft 3 603 continues to move to the curved section of the guide rail 604, separating from block 3 703; at this time, the tension spring 904 releases its elastic potential energy, pulling shaft 5 901 to reset, driving the sliding shaft 3 and the load-bearing plate 2 back to the initial position, ready for the next test; the whole process, through synergistic action, realizes the automatic unloading of the wind turbine and the automatic reset of the load-bearing plate 2, which is simple and efficient to operate.
