Description

TECHNICAL FIELD

[0001] The present invention relates to the field of industrial equipment testing, specifically to a quick test automatic locking device for winch and its matching winch batch intelligent comprehensive test bench. The technical solution aims to significantly improve the efficiency and accuracy of winch testing, providing a new solution for the field of industrial equipment testing. BACKGROUND

[0002] As a key device in the industrial field, the performance of winch directly affects work efficiency, safety and economic benefits, so it is crucial to conduct comprehensive and accurate performance testing. However, traditional winch testing methods have many limitations: static load testing cannot simulate dynamic load conditions in actual work, with low testing efficiency; field measurement is greatly affected by environmental factors, with unstable results and safety risks; simple bench testing cannot accurately simulate complex dynamic load conditions, with limited testing items. These methods generally face challenges such as low testing efficiency, unrealistic testing conditions, incomplete testing items, insufficient automation and intelligence, limited data collection and analysis capabilities, and low testing standardization.

[0003] To address these issues, some innovative testing methods and devices have been proposed. For example, a winch linear velocity measuring device (Patent No. CN104931721 B) provides a higher precision measurement method. The device includes a drum diameter measurement module, a drum speed measurement module, and a winch linear velocity calculation module. By measuring the current steel wire rope drum diameter r and the drum speed ω, the outermost layer of the steel wire rope linear velocity v on the drum is calculated (v = ω·r). This method can complete the online detection of the linear velocity of the winch steel wire rope within the allowable accuracy range, significantly improving the measurement accuracy. Another winch parameter measuring device (Patent No. CN204649766U) focuses on the accurate measurement of drum speed. The device uses a speed measuring gear ring and a proximity switch to measure the drum speed. The speed measuring gear ring is installed on the drum side plate, and the outer circumference is evenly distributed with protruding teeth. When the drum rotates, the protruding teeth sequentially pass through the proximity switch, achieving high-precision speed measurement.

[0004] Although these innovative technologies have made significant progress in improving measurement accuracy and achieving online detection, providing new ideas and methods for winch performance testing, they still cannot fully solve all the challenges faced by traditional testing methods. In particular, there is still much room for improvement in terms of multi-station simultaneous testing, simulating complex dynamic loads, improving testing efficiency, enhancing automation and intelligence, and providing comprehensive performance evaluation. SUMMARY

Example 2:

[0053] This embodiment proposes a winch rapid test automatic locking device, which aims to significantly improve the test efficiency of the winch and simplify the test process. This innovative design not only realizes batch testing of the winch, but also greatly reduces the manual operation time through a unique automatic locking mechanism. The device is mainly applied to winch test tables, such as Figure 7 as shown.

[0054] The test bench mainly consists of four parts: a planar base, a rotating body, installation stations for the winches under test, and test lines. The planar base 1 is a fixed planar structure with a central accommodating space, serving as the supporting foundation for the entire test bench. The rotating body 2 is located at the center of the planar base 1 and has at least an upper plane structure, such as a disc structure, which can rotate along its own axis via a power mechanism. Multiple installation stations 3 for the winches under test are located near the edge of the upper plane of the rotating body 2, arranged equidistantly in a circle, and located on the same radial dimension. Each installation station 3 is equipped with a device for temporarily fixing the winch under test, which can be a bolt-locking type or a power clamp type. Multiple test lines 4, corresponding to the number and position of the installation stations 3, are set on the planar base 1, extending radially to correspond to the installation stations 3. This design enables batch testing of winches and improves testing efficiency.

[0055] This intelligent integrated testing platform for batch winches offers significant advantages. First, during tensile testing, the stress at multiple winch installation stations 3 is symmetrically distributed, causing the stress borne by the foundation structure to cancel each other out, greatly improving the structure's stability and durability. Second, the rotation function of the gyratory body 2 allows for the installation of winch-laying auxiliary devices at fixed positions on the planar foundation 1. Rotation allows any winch installation station 3 to align with the auxiliary device, enabling operators to complete the installation of all winches in a fixed location, improving work efficiency and safety. This design not only achieves mechanical balance during the testing process but also simplifies the winch installation and testing procedures, providing convenient conditions for batch testing.

[0056] In a specific embodiment, such as Figure 7 As shown, the structure of test line 4 includes a test frame 41, a track 42, a sliding table 43, a test power unit 44, and a test data acquisition unit. The test frame 41 is a fixedly installed elongated structure, serving as the basic support for the entire test line. The track 42 is fixed to the upper surface of the test frame 41 and is used to guide the movement of other components. From the center of the rotating body 2 to the far end, the sliding table 43, the test power unit 44, and the test data acquisition unit are arranged sequentially. The sliding table 43 is equipped with a cable cage 431, which can slide along the track 42. The test power unit 44 includes a mounting base 441 and a winch 442 fixed thereon. The winch 442 is arranged parallel to the winch under test in the winch installation station 3, and the drums of the two winches are parallel.

[0057] The working principle of this intelligent integrated testing platform for batch winches is as follows:

[0058] The free end of the cable of winch 442 is pulled out and fixed on the drum of the winch being tested. After the winch being tested is started and works normally, winch 442 counteracts the pulling force generated by the winch being tested and controls the loosening and tightening of the cable according to the preset program. The test data acquisition unit collects multiple data in real time, including the pulling force generated by the winch being tested, the elongation of the cable, the counterforce of winch 442, the time of the test process, the power consumption of the winch being tested, and other related parameters such as temperature and vibration. These data are sent to the central control system in real time through the data transmission interface, which is used to analyze the performance indicators of the winch being tested, such as maximum pulling force, continuous working ability, and energy efficiency. This design can comprehensively test the performance of the winch, including static and dynamic load testing, durability testing, and efficiency testing. By adjusting the working parameters of winch 442, various actual working conditions can be simulated to comprehensively evaluate the performance and reliability of the winch being tested. In some specific embodiments, the fast connection and self-locking device 5 is designed for the test winch 01 with a base plate structure 02 as shown in the figure, which is used to quickly install and disassemble this type of winch to improve efficiency and replace other complex or time-consuming locking mechanisms. Figure 13 The fast connection and self-locking device 5 is designed for the test winch 01 with a base plate structure 02 as shown in the figure, which is used to quickly install and disassemble this type of winch to improve efficiency and replace other complex or time-consuming locking mechanisms.

[0059] The structure and working principle of the fast connection and self-locking device 5 are as follows:

[0060] The mounting seat 441 is designed to be slidable with the track 42. An actuator 51 for locking the test winch 01 is provided at each test winch installation station 3. The self-locking mechanism uses the pulling force of the cable during testing to drive the mounting seat 441 to move at the initial stage of testing, so that it abuts against the test frame 41, thereby pushing the test frame 41 as a whole to move towards the actuator 51. A power conversion mechanism 52 is provided between each test frame 41 and the actuator 51 to convert the movement of the test frame 41 into the locking power of the actuator 51.

[0061] The actuator 51 includes a winch mounting seat 511 having an upper plane 03 close to or larger than the plane area of the base plate structure 02, which can be detachably fixed at the test winch installation station 3; a driving jaw 512 and a passive jaw 513 hinged on both sides of the upper plane 03, respectively, corresponding to the two directions of the base plate structure 02 in the winch parallel to the drum; and a linkage assembly 514 connecting the driving jaw 512 and the passive jaw 513 to form a linkage mechanism to realize synchronous clamping or releasing.

[0062] This design has the advantages of high automation, quick installation and disassembly, strong adaptability, and simple operation. It skillfully utilizes the mechanical properties during testing to achieve quick and stable locking of the winch, while ensuring the safety and reliability of the testing process, greatly improving the testing efficiency and reducing human error and labor intensity.

[0063] The structure design of the driving jaw 512 and the passive jaw 513 is as follows:

[0064] Both are rigid plate bending or one-time forming die casting, one end of the force element has a hook, the hinge axis is parallel to the upper plane 03 and the hinge position is close to the hook. After the installation of the active jaw 512, its hinge axis extends downward in the direction away from the capstan mounting seat 511, and the end is provided with a horizontal roller 21 parallel to the hinge axis. The passive jaw 513 extends downward along the hinge axis and bends to the bottom surface of the capstan mounting seat 511, and the end is provided with a roller 22, which is convenient for linkage with the active jaw 512.

[0065] The linkage assembly 514 includes: transmission gears 515 fixed on both sides of the end of the active jaw 512 coaxial with the hinge axis; a sliding bar 516 having a toothed section meshing with the transmission gear 515 at one end and a slope 04 contacting the roller 22 at the other end. The sliding bar 516 is limited in movement range by the track 05 on the bottom surface of the capstan mounting seat 511. The hinge of the active jaw 512 and the passive jaw 513 is provided with a hinge shaft biasing spring, so that the two jaws are normally biased to clamp one end of the twist.

[0066] The angle design of the slope 04 makes the movement amount of the roller 22 equal to the clamping amount of the active jaw 512 converted by the upward movement of the horizontal roller 21, realizing the synchronous movement of the two jaws. When external force acts on the horizontal roller 21 to make it move upward, the movement is transmitted to the passive jaw 513 through the cooperation of the transmission gear 515 and the sliding bar 516. This mechanical transmission design ensures that the two jaws clamp the bottom plate structure 02 synchronously and uniformly, realizing stable and reliable locking of the test capstan.

[0067] The working principle of the quick connection self-locking device 5 is as follows:

[0068] When the horizontal roller 21 moves upward, it causes the two jaws to act on the bottom plate structure 02 synchronously and with the same clamping stroke. This ingenious mechanism design utilizes the principle of mechanical transmission to realize the cooperative movement of the active and passive jaws, ensuring the quick, uniform and reliable clamping of the test capstan.

[0069] The power conversion mechanism 52 mainly includes a wedge-shaped block 521 and a matching mounting seat 522 for stable parallel sliding. The wedge part of the wedge-shaped block 521 is designed below the horizontal roller 21. At the beginning of the test, the wedge-shaped block 521 moves, and the contact angle with the horizontal roller 21 gradually increases, so that the horizontal roller 21 is stably and continuously pushed upward. This design converts the horizontal movement of the test stand 41 into the vertical upward movement of the horizontal roller 21, thereby activating the linkage assembly 514. The upward movement of the horizontal roller 21 drives the active jaw 512 to rotate, and at the same time, through the cooperation of the transmission gear 515 and the sliding bar 516, the passive jaw 513 is synchronously rotated, finally realizing the stable clamping of the test capstan.

[0070] This structural design not only considers convenience and reliability, but also helps to improve testing efficiency and accuracy.
