Description

Technical Field

[0001] The present invention relates to the field of industrial equipment testing technology, and in particular to a batch intelligent comprehensive test bench for winches and a test method thereof. The present invention is mainly applied to performance testing of various types of winches, including but not limited to winches of various models and specifications used in the fields of construction, navigation, mining, forestry, oil drilling, military, etc. Background Art

[0002] As an important lifting equipment, winch is widely used in many fields such as construction, navigation, mining, forestry, etc. With the continuous advancement of industrial technology, the performance requirements for winches are also increasing. In order to ensure the quality and reliability of the winch, it is particularly important to conduct comprehensive performance testing. At present, the winch test mainly adopts the single-machine test method, that is, only one winch can be tested at a time. This method has the defects of low testing efficiency, complex operation, low equipment utilization, unstable testing environment, low data acquisition and analysis efficiency, and mechanical balance problems. In addition, how to quickly and accurately install and replace the winch is a key factor in improving testing efficiency. Existing test equipment is often designed for specific models of winches, and it is difficult to adapt to the testing needs of winches of different specifications and models.

[0003] In response to these problems, some improved technologies have been proposed. For example, an electro-hydraulic controlled winch test bench (authorization announcement number CN 201233291Y) provides a solution with easy operation, high precision, high work efficiency and multiple functions, including a quick installation fixture, a multi-stage drum gear coupling, an integrated torque sensor and a tachometer. Another winch rotation detection device and method (authorization announcement number CN 106370887 B) uses a sensing block and a proximity sensor to avoid direct contact, reduce vibration effects, and accurately detect the winch rotation direction and angle through signal phase difference analysis.

[0004] Although these technologies have improved the efficiency and accuracy of winch testing in some aspects, they are still insufficiently adaptable, have limited automation, and there is still room for improvement in testing efficiency. Summary of the invention

[0005] In view of this, the present invention provides an innovative intelligent integrated test bench for winches, which can test multiple winches at the same time and greatly improve the test efficiency. Its core innovations include the design of the gyroscopic body, the quick-connect self-locking device, the power conversion mechanism, etc. These designs not only improve the automation and efficiency of the test, but also enhance the safety and accuracy of the test process. The invention also provides a systematic test method to ensure the standardization and repeatability of the test process.

[0006] The technical solution of one of the themes of the embodiments of the present invention is implemented as follows: a batch intelligent comprehensive test bench for winches includes: a plane base, the center of which has a accommodating space; a gyro, which is arranged at the center of the plane base, has an upper plane, and can rotate along its own axis; a plurality of installation stations for the winches to be tested, which are arranged equidistantly in a circle near the edge of the upper plane of the gyro; a plurality of test lines corresponding to the number and position of the installation stations for the winches to be tested, which are arranged on the plane base; wherein each of the test lines includes a test frame, a track arranged on the test frame, a sliding table, a test power unit and a test data acquisition unit, and the sliding table, the test power unit and the test data acquisition unit are arranged in sequence along the track from the center of the gyro to the distal end.

The beneficial effect of this technical solution is that the design of the transmission gear and the sliding bar realizes the precise synchronous movement of the active pliers foot and the passive pliers foot. The setting of the guide rail limits the movement range of the sliding bar and ensures the controllability of the movement.

[0012] According to a preferred embodiment, the hinges of the active and passive pliers are both provided with a shaft bias spring that causes the two pliers to twist toward one end of the clamping in a normal state.

The beneficial effect of this technical solution is that the key steps in the test process are described in detail, ensuring the accuracy and safety of the test. The automatic activation and self-locking functions of the locking mechanism improve the stability and reliability of the test process.

DETAILED DESCRIPTION

[0030] The following will be combined with the attached Figure 1-Figure 7 The preferred embodiments of the present invention are described in detail. It should be noted that the following description is only a preferred embodiment of the present invention, rather than a limitation of the present invention. Those skilled in the art should understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the attached claims.

[0031] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. Example

[0032] like Figure 1 As shown, the present invention proposes a batch intelligent comprehensive test bench for winches. The test bench mainly includes the following parts:

[0033] 1) Plane foundation 1: A fixed planar structure with a central storage space, serving as the support foundation for the entire test bench.

[0034] 2) Rotating body 2: It is arranged at the center of the plane base 1 and has at least an upper plane structure, such as a disk structure. The rotating body 2 can rotate along its own axis through a power mechanism.

[0035] 3) Installation station 3 for the capstan to be tested: In terms of position and layout, multiple installation stations 3 for the capstan to be tested are arranged near the edge of the upper plane of the gyroscopic body 2, arranged equidistantly in a circle, and located in the same radial dimension. In addition, a device for temporarily fixing the capstan to be tested is provided in each installation station 3 for the capstan to be tested, which may include, for example: a) Bolt locking type: the station is provided with prefabricated installation holes, which are fixed by bolts matching the capstan to be tested; b) Power clamp type: a clamp system equipped with an external power drive, which can achieve rapid locking and release through hydraulic, pneumatic or electric mechanisms.

[0036] 4) Test line 4: multiple lines corresponding to the number and position of the winch installation stations 3 to be tested (position correspondence refers to radial extension), arranged on the plane foundation 1.

[0037] This design has the following advantages:

[0038] First, mechanical balance: when multiple winch installation stations 3 are subjected to tensile testing, the stress is symmetrically distributed. This design allows the stresses borne by the foundation structure to offset each other, greatly improving the stability and durability of the structure.

[0039] Second, convenient operation: The rotating function of the gyro 2 allows the auxiliary device for hoisting the capstan to be set at a fixed position on the plane foundation 1. Through the rotation of the gyro 2, any installation station 3 of the capstan to be tested can be docked with the auxiliary device for hoisting the capstan, so that the operator can complete the installation of all the capstans to be tested at a fixed position, thereby improving work efficiency and safety.

[0040] This design not only achieves mechanical balance during the test, but also greatly simplifies the installation and testing process of the winch, providing convenient conditions for batch testing.

[0041] In some specific embodiments, referring to Figure 1 , the structure of test line 4 is as follows, including:

[0042] 1) Test stand 41: a fixedly installed long strip structure, serving as the basic support for the entire test line.

[0043] 2) Track 42: fixed on the upper surface of the test frame 41, used to guide the movement of other components.

[0044] 3) Arranged in sequence from the center to the far end of the gyroscopic body 2 are: a sliding table 43, a test power unit 44, and a test data acquisition unit;

[0045] Among them, a cable cage 431 is provided on the sliding table 43, and the sliding table 43 is installed on the track 42 and can slide along the track; the test power unit 44 includes a mounting seat 441 and a winch 442 fixedly installed on the mounting seat 441, and the installation direction of the winch 442 is parallel to the winch to be tested in the winch installation station 3, that is, the drums of the two winches are in a parallel state.

[0046] Working principle:

[0047] The free end of the cable in the winch 442 is pulled out and fixed on the drum of the winch to be tested. The winch to be tested is started and works normally. The winch 442 resists the pulling force generated by the winch to be tested and controls the loosening and tightening of the cable according to a preset program.

[0048] The test data acquisition unit collects the following data in real time:

[0049] The tension generated by the tested winch, the elongation of the cable, the reaction force of the winch 442, the time during the test, the power consumption of the tested winch, and other relevant parameters (such as temperature, vibration, etc.). The collected data is sent to the central control system in real time through the data transmission interface for analyzing the performance indicators of the tested winch, such as maximum tension, continuous working capacity, energy efficiency, etc.

[0050] This design allows for comprehensive performance testing of the winch, including static and dynamic load testing, durability testing, and efficiency testing. By adjusting the working parameters of the winch 442, various actual working conditions can be simulated to fully evaluate the performance and reliability of the tested winch.

[0051] In some specific embodiments, Figure 7 For the test winch 01 with the bottom plate structure 02 shown, we have designed a quick-connect self-locking device 5 for quickly installing and disassembling this type of winch to improve efficiency and replace other complex or time-consuming locking mechanisms. The specific structure and working principle of the quick-connect self-locking device 5 are as follows:

[0052] 1) The mounting seat 441 is designed to be slidably matched with the track 42 and can move on the track;

[0053] 2) An actuator 51 for locking the test capstan 01 is provided at each capstan installation station 3 to be tested;

[0054] 3) A self-locking mechanism, which utilizes the tension of the cable during the test to first drive the movement of the mounting seat 441 in the initial stage of the test, and allows the movement of the mounting seat 441 to resist the test frame 41, so that the test frame 41 moves as a whole toward the actuator 51;

[0055] 4) A power conversion mechanism 52 is provided between each test frame 41 and the actuator 51 . The power conversion mechanism 52 transmits power to the actuator 51 , and converts the movement of the test frame 41 into locking power of the actuator 51 .

[0056] Detailed structure of the actuator 51:

[0057] a) Winch mounting seat 511: it has an upper plane 03 that is close to or larger than the plane area of ​​the bottom plate structure 02 and can be detachably fixed to the winch mounting station 3 to be tested;

[0058] b) Clamp foot design: active clamp foot 512 is hinged on one side of the upper plane 03; passive clamp foot 513 is hinged on the other side of the upper plane 03; the positions of the two sides correspond to the two directions of the bottom plate structure 02 in the capstan parallel to the drum;

[0059] c) Linkage assembly 514: connects the active clamp foot 512 and the passive clamp foot 513 to form a linkage mechanism to achieve synchronous clamping or loosening.

[0060] The advantages of this design are: high degree of automation, using the test force to automatically trigger the locking mechanism; fast installation and disassembly, greatly improving the test efficiency; strong adaptability, can be used for a variety of winch models with similar bottom plate structures; simple operation, reducing human errors and labor intensity. The design of the quick-connect self-locking device 5 cleverly utilizes the mechanical characteristics during the test process, realizes the fast and stable locking of the winch, and ensures the safety and reliability of the test process.

[0061] Further, see Attachment Figure 5-Figure 6 The active clamp foot 512 and the passive clamp foot 513 are designed as follows:

[0062] The active clamp foot 512 and the passive clamp foot 513 are generally formed by bending rigid sheet materials or casting from a one-time molding die, and are force-bearing parts with a hook at one end. Their hinge axes are parallel to the upper plane 03 and the hinge parts are close to the hook. The difference is that after the active clamp foot 512 is installed, it extends in a direction away from the capstan mounting seat 511 at a section below the hinge axis (so that its end is separated from the capstan mounting seat 511 by a distance), and a horizontal roller 21 parallel to the hinge axis is provided at the end. The passive clamp foot 513 also extends downward from the hinge axis, and the extension direction is bent toward the bottom surface of the capstan mounting seat 511. A roller 22 is provided at the end of the extension. The purpose of this design is to facilitate the linkage with the active clamp foot 512.

[0063] Accordingly, the structure of the linkage component 514 includes:

[0064] The transmission gear 515 is respectively fixed to the two side ends of the active clamp foot 512 and is coaxial with the hinge axis thereof. One end of the transmission gear 515 has a tooth segment meshing with the teeth of the transmission gear 515 and the other end of the sliding bar 516 has an inclined surface 04 contacting and matching with the roller 22. The sliding bar 516 is limited in its moving range by the guide rail 05 fixed to the bottom surface of the capstan mounting seat 511, and the hinges of the active clamp foot 512 and the passive clamp foot 513 are provided with a shaft bias spring that makes the two clamp feet biased to clamp one end to twist under normal conditions. The angle of the inclined surface 04 is just that when it contacts with the roller 22 and moves relative to the roller 22, the movement range converted into the clamping of the passive clamp foot 513 is equal to the movement range converted into the clamping of the active clamp foot 512 by the movement of the horizontal roller 21 moving upward due to the external force. That is to say, this design realizes the synchronous movement of the active clamp foot 512 and the passive clamp foot 513. When external force acts on the horizontal roller 21 to move it upward, this movement is transmitted to the passive clamp foot 513 through the cooperation of the transmission gear 515 and the sliding bar 516. The precise angle design of the inclined plane 04 ensures the equal conversion of the movement: the upward movement distance of the horizontal roller 21 is converted into the clamping movement of the active clamp foot 512 through the mechanism, and at the same time, the movement of the inclined plane 04 is converted into the equal clamping movement of the passive clamp foot 513 through the roller 22. This ingenious mechanical transmission design ensures that the two clamp feet can clamp the bottom plate structure 02 synchronously and evenly, thereby achieving a stable and reliable locking of the test capstan.

[0065] Working principle:

[0066] With this design, when the horizontal roller 21 moves upward, the two clamping feet are forced to act on the bottom plate structure 02 synchronously and with the same clamping stroke. This mechanism design cleverly utilizes the principle of mechanical transmission, realizes the coordinated movement of the active and passive clamping feet, and ensures the rapid, uniform and reliable clamping of the test capstan. At the same time, the design of the structure also takes into account the convenience and reliability of use, which is conducive to improving the test efficiency and accuracy.

[0067] Accordingly, refer to Figure 2 and Figure 5 The structure and working principle of the power conversion mechanism 52 are as follows:

[0068] The power conversion mechanism 52 mainly includes two key components: a wedge block 521 and a matching mounting seat 522 that provides stable parallel sliding for the wedge block 521. The wedge portion of the wedge block 521 is designed to be below the horizontal roller 21. When the test process starts, the wedge block 521 starts to move. During this movement, the contact angle between the wedge portion and the horizontal roller 21 gradually increases. This gradually increasing angle design allows the horizontal roller 21 to be stably and continuously pushed upward.

[0069] The core advantage of this design is that it can convert the horizontal movement of the test frame 41 into the vertical upward movement of the horizontal roller 21. Through this movement conversion, the aforementioned linkage assembly 514 is activated. When the horizontal roller 21 rises, it drives the active clamp foot 512 to rotate, and at the same time, through the cooperation of the transmission gear 515 and the sliding bar 516, the passive clamp foot 513 rotates synchronously. This series of chain reactions ultimately achieves a stable clamping of the test capstan.

[0070] Furthermore, this design also has a self-locking feature. As the test force increases, the wedge block 521 is pushed deeper, thereby increasing the clamping force accordingly. This adaptive clamping force ensures that a stable and reliable clamping state can be maintained under different test forces, effectively preventing the capstan from loosening or moving during the test.

[0071] The design of this power conversion mechanism not only achieves efficient conversion of test force to clamping force, but also greatly improves the safety and reliability of the entire test process through its progressive and self-locking characteristics. At the same time, its simple design is also easy to maintain and adjust, which is conducive to improving the long-term stability and service life of the entire test system.

[0072] In summary of all the above embodiments, the overall working process of the winch batch intelligent comprehensive test bench is as follows:

[0073] 1. Initial preparation stage:

[0074] 1. The operator uses the rotation function of the gyro 2 to install the test capstan 01 one by one at each test capstan installation station 3 of the gyro 2 at a pre-set position. During the installation process, the active clamp foot 512 and the passive clamp foot 513 need to be opened to a certain angle to facilitate the smooth placement of the test capstan 01. The following methods can be used: manually pry the active clamp foot 512 or use other auxiliary devices. Under the action of the shaft bias spring, the two clamp feet can apply a certain clamping force to the test capstan 01.

[0075] 2. Through the rotation function of the gyrator 2, the first batch of test winches 01 are aligned with the corresponding test lines 4 respectively.

[0076] 2. Winch connection stage:

[0077] 1. The cables of the winches 442 in each test power unit 44 are respectively connected to the corresponding test winches 01 .

[0078] 2. The cable cage 431 on each sliding platform 43 ensures the safety of the cables during the test.

[0079] 3. Locking mechanism activation stage:

[0080] 1. The test starts and the cable generates initial tension.

[0081] 2. Each pulling force drives its own mounting seat 441 to move, thereby pushing the corresponding test frame 41 to move towards the actuator 51.

[0082] 3. Each power conversion mechanism 52 (wedge block 521 ) converts the horizontal movement of the test frame 41 into the vertical ascending movement of the horizontal roller 21 .

[0083] 4. Winch locking stage:

[0084] 1. The horizontal roller 21 rises, activating the linkage assembly 514.

[0085] 2. The active clamp foot 512 and the passive clamp foot 513 synchronously clamp the bottom plate structure 02 of the test capstan 01 through the cooperation of the transmission gear 515 and the sliding bar 516.

[0086] 3. As the test force increases, the wedge block 521 penetrates deeper, increasing the clamping force and achieving self-locking.

[0087] 5. Test execution phase:

[0088] 1. All test winches 01 start working normally at the same time.

[0089] 2. The winch 442 of each test power unit 44 controls the loosening and tightening of the cable according to a preset program to simulate various working conditions.

[0090] 3. Each test data acquisition unit collects various data (tension, elongation, power consumption, etc.) of the corresponding test winch 01 in real time.

[0091] 6. Data processing stage:

[0092] 1. The collected data is transmitted to the central control system in real time.

[0093] 2. The system analyzes the data and evaluates the performance indicators of each test winch 01.

[0094] 7. Test completion and replacement phase:

[0095] 1. After the test of winch 01 in the current batch is completed, the lock will be released uniformly.

[0096] 2. The gyroscopic body 2 rotates to move the tested capstan out of the testing position.

[0097] 3. The operator installs the next batch of winches 01 to be tested at the test station.

[0098] 4. Repeat the above process until all batches of winch tests are completed.

[0099] This process makes full use of the rotation function of the gyro and the design of the quick-connect self-locking device to achieve efficient, safe and reliable batch winch testing, greatly improving test efficiency and accuracy.
