[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Then, the steel wire rope 3 is wound around the capstan 2 for several turns, and then passes through each pulley in the pulley assembly 4 in turn, and finally connected with the tension sensor assembly 7, and then the test device is installed. By setting the limit assembly 5, the safe and stable operation of the hydraulic cylinder loading assembly 6 is ensured.

[0039] In an embodiment of the present invention, Figure 1-7 As shown, the pulley assembly 4 includes: a first fixed pulley 401, a second fixed pulley 402, a third fixed pulley 403 and a movable pulley 404, the first fixed pulley 401 is fixedly connected to the lower beam 105; the second fixed pulley 402 is fixedly connected to the upper beam 104; the third fixed pulley 403 is fixedly connected to the upper beam 104, and is arranged side by side with the second fixed pulley 402; the movable pulley 404 is arranged on the hydraulic cylinder loading assembly 6, and the movable pulley 404 is suspended in the air by the action of the wire rope 3.

[0040] By sequentially arranging the first fixed pulley 401, the second fixed pulley 402, the third fixed pulley 403 and the movable pulley 404 on the rectangular support frame, the multiple pulleys effectively transmit the traction force generated by the winch 2 to the hydraulic cylinder loading assembly 6 through the wire rope 3, ensuring that the force can be accurately transmitted along the predetermined path and avoiding the influence of unnecessary lateral force or torsional load on the system.

[0041] In an embodiment of the present invention, Figure 1-7 As shown, the hydraulic cylinder loading assembly 6 includes: a hydraulic cylinder support 601, a hydraulic cylinder body 603, a hydraulic rod 604, a first joint bearing 605 and a first shackle 606; the hydraulic cylinder support 601 is fixedly connected to the lower cross beam 105; the hydraulic cylinder support 601 is rotatably connected to the hydraulic cylinder body 603 through a support pin 602; the hydraulic rod 604 is slidably connected to the inner wall of the hydraulic cylinder body 603; the first joint bearing 605 is threadedly connected to the hydraulic rod 604; one end of the first shackle 606 is connected to the first joint bearing 605, and the other end of the first shackle 606 is connected to the movable pulley 404.

[0042] The hydraulic cylinder body 603 and the hydraulic rod 604 together constitute a hydraulic cylinder, to which is connected a loading hydraulic system, which is an integral device for controlling and providing hydraulic oil pressure, and includes but is not limited to a hydraulic pump station, a control valve group, hydraulic pipelines, sensors, and a control system.

This allows the hydraulic cylinder to work in different positions and postures without being affected by the uneven force transmission caused by angle deviation, and ensures that the force applied by the hydraulic cylinder can be accurately transmitted to the tested capstan 2 in the expected direction, rather than being dispersed in other directions. This is very important for obtaining accurate and reliable test results; in addition, when performing dynamic loading tests, the upper and lower movable connections of the hydraulic cylinder can better simulate the dynamic load conditions that the capstan 2 is subjected to in the actual working environment. It allows the hydraulic cylinder to automatically adjust its position according to the actual situation to respond to load fluctuations and provide a more realistic working scene simulation.

[0045] In an embodiment of the present invention, Figure 1-7 As shown, the limiting assembly 5 includes: a bracket 501 and a limiting ring 503; the bracket 501 is fixedly connected to the lower cross beam 105; the bracket 501 is connected to the limiting ring 503 through a locking bolt 502, and the limiting ring 503 and the bracket 501 surround the circumference of the hydraulic cylinder body 603, and a gap is left in the circular ring surrounded by the hydraulic cylinder body 603 and the limiting ring 503 and the bracket 501.

[0046] By setting the hydraulic cylinder body 603 in the circle surrounded by the limiting ring 503 and the bracket 501, it is ensured that the position of the hydraulic cylinder body 603 remains unchanged during the test, avoiding the influence of the position displacement of the hydraulic cylinder body 603 on other components; at the same time, the limiting ring 503 can be opened by loosening the locking bolt 502, which makes the installation and removal of the hydraulic cylinder body 603 more convenient.

[0048] The upper crossbeam 104 is composed of two upper crossbeam I-beams 1041, and the two upper crossbeam I-beams 1041 are fixedly connected by an upper crossbeam connecting plate 1042; the lower crossbeam 105 is composed of two lower crossbeam I-beams 1051, and the two lower crossbeam I-beams 1051 are fixedly connected by a lower crossbeam connecting plate 1052; in addition, the first fixed pulley 401 and the hydraulic cylinder support 601 are fixedly connected to the lower crossbeam connecting plate 1052, and the lifting ring 701, the second fixed pulley 402, the third fixed pulley 403 and the lifting ring 701 are fixedly connected to the upper crossbeam connecting plate 1042.

[0049] The legs 101 , the reinforcing ribs 103 , the upper crossbeam I-beam 1041 and the lower crossbeam I-beam 1051 together form a strong and stable rectangular support frame, ensuring the safe and reliable operation of all components during the performance test of the capstan 2 .

[0050] In an embodiment of the present invention, Figure 1-7 As shown, the capstan 2 is also provided with a front guide pulley 201 and a rear guide pulley 205 .

[0051] By providing two guide rope wheels, the problems of the wire rope 3 being knotted or out of the groove during operation are reduced, and the direct contact between the wire rope 3 and other parts of the capstan 2 is reduced, thereby reducing friction and wear and extending the service life of the wire rope 3.

[0052] In addition, the capstan 2 is also provided with two rollers 204, two support plates 203 and four support plate pins 202. When installing the wire rope 3, first pull out the four support plate pins 202 and rotate the two support plates 203. At this time, the roller 204 is in a cantilever state and can be wound with the wire rope 3. After winding it around the roller 204 for multiple turns, it comes out from the rear guide rope wheel 205. After the wire rope 3 is wound, rotate the two support plates 203 and insert and lock the four support plate pins 202. The installation of the capstan 2 is completed.

[0054] According to a second aspect of the present invention, a method for testing performance of a capstan mill is provided, the testing method comprising the following steps:

[0055] S1: Arrange the capstan 2 to be tested correctly in the test area, ensure that it is located at a predetermined position of the rectangular support frame, and ensure that it is stable.

[0056] S2: Install the hydraulic cylinder loading assembly 6 and the tension sensor assembly 7, and ensure that their connection with the rectangular support frame is firm and reliable.

[0057] S3: After the steel wire rope 3 is wound around the capstan 2 for several turns, it passes through each pulley in the pulley assembly 4 in turn and is connected to the tension sensor assembly 7 to ensure that the connection between the movable pulley 404 and the hydraulic cylinder loading assembly 6 is firm and reliable.

[0058] S4: Start the loading hydraulic system of the hydraulic cylinder loading assembly 6 to prepare for the load test.

[0059] S5: Rated load test: A rated load test of the capstan 2 is performed to verify its performance under standard working conditions.

[0060] S6. Ultimate load test: Perform an ultimate load test on the capstan 2 to evaluate the stability and safety of the capstan 2 when the load exceeds the rated load.

[0061] S7, reliability test: Conduct reliability test on the capstan 2 to simulate the performance of the capstan 2 under long-term working conditions to ensure its continuous and stable operation.

[0062] S8: First, the tension sensor 704 is used to collect the tension data applied by the capstan 2 through the wire rope 3, and then the loading force and time of the hydraulic cylinder are obtained. Finally, the data is processed by a computer to evaluate whether the performance of the capstan 2 meets the predetermined working requirements.

[0063] Example:

[0064] Align the front guide pulley 201 of the capstan 2 to be tested with the first fixed pulley 401, pull out the four support plate pins 202, and rotate the two support plates 203. At this time, the drum 204 is in a cantilever state and can be wound with the wire rope 3. Specifically, one end of the wire rope 3 enters from the front guide pulley 201, is wound on the drum 204 for multiple turns, and then exits from the rear guide pulley 205. After the wire rope 3 is wound, the two support plates 203 are rotated and the four support plate pins 202 are inserted and locked. The installation of the capstan 2 device is completed.

[0065] Open the limiting ring 503 by loosening the locking bolt 502, and then rotatably connect the hydraulic cylinder body 603 to the hydraulic cylinder bracket 601 through the bracket pin 602. After rotating the hydraulic cylinder body 603 to be perpendicular to the lower beam 105, wrap the hydraulic cylinder body 603 and limit it between the bracket 501 and the limiting ring 503 through the locking bolt 502, and then hang the tension sensor assembly 7 to be connected to the upper beam connecting plate 1042.

[0066] The steel wire rope 3 is passed through the first fixed pulley 401 , the second fixed pulley 402 , the third fixed pulley 403 , and the movable pulley 404 in sequence, and finally the steel wire rope 3 is looped into the third shackle 706 for active connection, and then the movable pulley 404 is movably connected to the first shackle 606 .

[0067] Start the loading hydraulic system on the hydraulic cylinder and carry out the rated load performance test of the capstan 2. Set the stable / dynamic loading value of the hydraulic cylinder by adjusting the pressure value of the loading hydraulic system as needed. At this time, the capstan 2 can perform the lifting work and perform the lowering work after reaching the top. During the entire lifting process, the hydraulic cylinder always maintains a stable / dynamic loading state. Stable loading can simulate the force applied by the heavy object to the wire rope 3, and dynamic loading can simulate the force applied by the heavy object to the wire rope 3 under the action of unstable wind force. Finally, through data collection and processing, determine whether the rated load performance of the capstan 2 meets the requirements.

[0068] Start the loading hydraulic system on the hydraulic cylinder, carry out the ultimate load performance test of the capstan 2, set the hydraulic cylinder loading value to 1.25 times the rated traction force of the capstan 2, and in some embodiments, the multiple here is also adjusted according to the test standards of capstan 2 with different specifications. When the capstan 2 performs the lifting work to the top, the capstan 2 is braked and suspended for 5 minutes. At this time, the hydraulic cylinder always maintains a stable / dynamic loading state. Finally, through data acquisition and processing, it is determined whether the ultimate load performance of the capstan 2 meets the requirements. In addition, the overload protection performance and braking state performance of the capstan 2 can also be tested under this test.

[0069] Start the loading hydraulic system on the hydraulic cylinder, and carry out the reliability test of the capstan 2. Set the hydraulic cylinder loading value to 0.7 times the rated traction force of the capstan 2. After the capstan 2 is lifted for at least 2m, it is lowered. During the process, the hydraulic cylinder loading device 6 always maintains a stable / dynamic loading state. Repeat the lifting and lowering for 2h. Finally, through data collection and processing, determine whether the reliability of the capstan 2 under long-term operation meets the requirements.

[0070] The present invention describes in detail a capstan performance testing device and a testing method thereof. The device is designed to be safe and reliable. The hydraulic loading device can provide steady-state and dynamic loading to achieve stepless load testing of the capstan 2. This is not only suitable for capstans 2 of various specifications, but also can simulate load fluctuations caused by wind and swing during actual lifting. In addition, the tension sensor assembly 7 used can provide accurate loading data, thereby providing a reliable process for performance testing of the capstan 2 under actual working conditions.

[0071] It should be noted that the specific models and specifications of the tension sensor 704, the capstan 2, the first fixed pulley 401, the second fixed pulley 402, the third fixed pulley 403, the movable pulley 404, and the hydraulic cylinder need to be selected and determined according to the actual specifications of the device, so they will not be described in detail.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
