[0002] The wind-assisted propulsion rotor is a tall and large circular cylindrical structure. After being loaded onto a ship, when the ship is loading or unloading goods or encountering a low bridge, it is necessary to use a hydraulic tilting device to switch the wind-assisted propulsion rotor between a horizontal position and a vertical position as needed.

[0003] After the hydraulic tilting device of the wind-assisted propulsion rotor is manufactured, it needs to be fully tested to ensure the safety of the system. Since the wind-assisted propulsion rotor is a tall and large circular cylindrical structure with a large weight and a high center of gravity, in the prior art, the wind-assisted propulsion rotor is directly used for hydraulic tilting test, and the weight and the center of gravity height of the tooling cannot be adjusted, which is equivalent to directly conducting a full-load test and has a relatively high risk.

[0027] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all structures.

[0029] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0030] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying 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 construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] On the one hand, this embodiment provides a test tooling for a wind-assisted rotor hydraulic tipping device, and this test tooling for a wind-assisted rotor hydraulic tipping device is used to replace the wind-assisted rotor to be tested for tipping tests.

[0032] Please refer to Figures 1 to 4, the test tooling for the hydraulic tilting device of the wind-assisted rotor includes a suspension connection mechanism 2 and N cylinders 11. The suspension connection mechanism 2 is used to connect with a hoisting device. The suspension connection mechanism 2 can be connected to any one of the cylinders 11, and N is an integer not less than 2. Connection parts 111 are provided at both ends of each cylinder 11, and the connection parts 111 of any two cylinders 11 can be detachably connected. The N cylinders 11 are respectively the first cylinder, the second cylinder... the Nth cylinder. The suspension connection mechanism 2 and the N cylinders 11 can combine to form N kinds of simulated rotors. The ith kind of simulated rotor is spliced by the suspension connection mechanism 2 and i cylinders 11. Among them, when i is equal to 1, the cylinder is the first cylinder, and the suspension connection mechanism 2 is connected to one end of the first cylinder. When i is a positive integer greater than 1 and less than or equal to N, the i cylinders 11 are respectively the first cylinder... the ith cylinder. The first cylinder... the ith cylinder are coaxially connected in sequence to form a main body simulation part 1, and the suspension connection mechanism 2 is connected to the cylinder 11 at one end of the main body simulation part 1. The center of gravity height of the first cylinder is L1, the center of gravity height of the Nth cylinder is L3, and the center of gravity heights of the remaining cylinders 11 are all L2, where L1 > L2 > L3. The center of gravity height and weight of the Nth kind of simulated rotor are the same as those of the wind-assisted rotor to be tested. Among the remaining simulated rotors, from the (N - 1)th kind of simulated rotor to the first kind of simulated rotor, the weight and center of gravity height of the simulated rotor gradually decrease. With such a setting, when conducting the test of the hydraulic tilting device, first, the first kind of simulated rotor composed of the first cylinder is used for the first test of the hydraulic tilting device. Then, the first cylinder and the second cylinder are connected to form the second kind of simulated rotor for the second test of the hydraulic tilting device, and so on. The hydraulic tilting device is tested with graded loading. The center of gravity height of the first cylinder is set to be the largest, so that during the test process, as the number of tests increases, the increased center of gravity height of the simulated rotor has a gradually decreasing trend, which can further ensure the safety of the test. The center of gravity heights of the second cylinder to the (N - 1)th cylinder are the same, so the change amounts of the center of gravity heights of the second kind of simulated rotor to the (N - 1)th kind of simulated rotor are the same, which is beneficial to identifying the change trend of the performance parameters of the hydraulic tilting device caused by the change of the center of gravity height during each loading, and is convenient for theoretical analysis. And the center of gravity height of the Nth cylinder is set to be the smallest. At this time, the center of gravity height of the simulated rotor reaches the rated center of gravity height of the hydraulic tilting device, that is, it has the same center of gravity height as the wind-assisted rotor to be tested, which is beneficial to evaluating the reliability of the hydraulic tilting device.

[0033] When conducting the hydraulic dumping device test, the test is carried out in sequence starting from the first simulated rotor. Specifically, when the i-th simulated rotor is tested, if the test is qualified, the subsequent simulated rotors are tested until the N-th simulated rotor is tested. If the N-th simulated rotor is tested, it indicates that the hydraulic dumping test of the wind-assisted rotor to be tested is qualified; if the i-th simulated rotor test is unqualified, there is no need to perform dumping tests on the subsequent simulated rotors, and it indicates that the dumping test of the wind-assisted rotor to be tested is unqualified, and the weight and center of gravity height of the wind-assisted rotor to be tested should not exceed the weight and center of gravity height corresponding to the i-th simulated rotor. Therefore, the wind-assisted rotor hydraulic dumping device test fixture can ensure the safety and reliability of the test when used for the dumping device test.

[0034] Optionally, see Figure 1 , the weight of the first cylinder is G1, the weight of the Nth cylinder is G3, and the weights of the remaining cylinders 11 are all G2, G1>G2>G3. The hydraulic dumping device is subjected to a graded loading test, and the weight of the first cylinder is set to the maximum, so that during the test, as the number of tests increases, the weight added by the simulated rotor tends to gradually decrease, which can further ensure the safety of the test. The weights of the second cylinder to the N-1th cylinder are the same, and the weight changes from the second simulated rotor to the N-1th simulated rotor are the same, which is conducive to identifying the changing trend of the performance parameters of the hydraulic dumping device brought about by each change in loading weight, and is convenient for theoretical analysis. The weight of the Nth cylinder is set to the minimum, at which time the weight of the simulated rotor reaches the rated weight of the hydraulic dumping device, that is, it has the same weight as the wind-assisted rotor to be tested, which is conducive to evaluating the reliability of the hydraulic dumping device.

[0035] For details, please refer to Figures 1 to 3 , along the direction in which the cylinders 11 of the main simulation part 1 are connected in sequence, the connecting parts 111 arranged at both ends of each cylinder 11 are respectively an upper flange 1111 and a lower flange 1112; the wind-assisted rotor hydraulic dumping device test fixture also includes a plurality of bolts and a plurality of nuts. In any two cylinders 11 connected to each other, the plurality of bolts sequentially pass through the lower flange 1112 of one cylinder 11 and the upper flange 1111 of the other cylinder 11, and the plurality of bolts and the plurality of nuts are threadedly connected in a one-to-one correspondence. With such a configuration, the installation and disassembly operations between the cylinders 11 are simple, and when conducting hydraulic dumping tests under different working conditions, the corresponding simulated rotor can be combined according to the needs, which shortens the test preparation time and improves the test efficiency.

[0036] Preferably, a plurality of bolts are evenly spaced along the circumferential direction of the connecting portion 111 to ensure that the two interconnected cylinders 11 are evenly stressed along the circumferential direction of the connecting portion 111, thereby ensuring that the two interconnected cylinders 11 are directly connected firmly and reliably.

[0037] Optionally, please refer to Figure 2 , the cylinder 11 includes a housing 112, a support plate 113 and a fixed counterweight 114. The support plate 113 is disposed inside the housing 112, and a limiting space is formed between the support plate 113 and the upper flange 1111. The fixed counterweight 114 is disposed in the limiting space. With such a setting, the design of the limiting space can effectively prevent the fixed counterweight 114 from shifting inside the cylinder 11. Avoiding the counterweight from shifting during the test, especially when simulating the tilting action of the rotor, which may affect the accuracy and reliability of the test.

[0038] Furthermore, the limiting space for placing the fixed counterweight 114 is located at the top of the cylinder 11. Compared with the fixed counterweight 114 being disposed at other positions of the cylinder 11, the center of gravity height of the cylinder 11 is increased, which is beneficial to reducing the size of the test tool for the hydraulic tilting device of the wind-assisted rotor, facilitating the assembly of the equipment and the actual operation of the test.

[0039] Furthermore, please refer to Figure 3 , the test tool for the hydraulic tilting device of the wind-assisted rotor further includes a plurality of movable counterweights 115. In the i-th simulated rotor, the movable counterweight 115 is used to be selectively loaded on the top of the i-th cylinder 11. Specifically, the i-th simulated rotor has the weight and the center of gravity height that simulate the real wind-assisted rotor. With such a setting, after the full-load test of the hydraulic tilting device is carried out using the i-th simulated rotor, the weight and the center of gravity height of the simulated rotor can be adjusted by loading the movable counterweight 115 to test the load limit of the hydraulic tilting device.

[0040] Preferably, please refer to Figure 1 and Figure 2 , the cylinder 11 further includes a plurality of reinforcing ribs 116. The plurality of reinforcing ribs 116 are all arranged at intervals on the outer periphery of the housing 112, and the plurality of reinforcing ribs 116 all extend along the axial direction of the housing 112. The setting of the reinforcing ribs 116 can strengthen the stiffness of the cylinder 11, thereby enhancing the ability of the cylinder 11 to resist deformation. Avoiding excessive deformation of the cylinder 11 during the tilting process, ensuring the shape and size stability of the simulated rotor, and making the test results more accurate and reliable.

[0041] Optionally, please refer to Figure 1 and Figure 4, the suspension connection mechanism 2 includes a connecting plate 21, a reinforcing member 22 and a plurality of lifting lugs 23. In the i-th simulated rotor, the connecting portion 111 of the connecting plate 21 and the i-th cylinder is detachably connected. The reinforcing member 22 is arranged on the connecting plate 21, and a plurality of lifting lugs 23 are all arranged on the reinforcing member 22. The lifting lugs 23 are used to connect with a lifting device. Preferably, the suspension connection mechanism 2 is also provided with an annular reinforcing plate to strengthen the strength of the connecting plate 21, and the annular reinforcing plate and the reinforcing member 22 are arranged on the same side of the connecting plate 21. With such an arrangement, during the loading operation, the connecting plate 21 is connected to the cylinder 11 to be loaded, the lifting lugs 23 are connected to the lifting device, and the cylinder 11 to be loaded is lifted by the lifting device to complete the loading. After the loading is completed, the suspension connection device can be removed from the simulated rotor. Similarly, during the unloading operation, the cylinder 11 to be unloaded can be unloaded from the simulated rotor through the suspension connection device. The setting of the suspension connection mechanism 2 facilitates the combination of various simulated rotors and improves the testing efficiency of the hydraulic tipping device.

[0042] Optionally, please refer to Figure 4 , the reinforcing member 22 includes a plurality of reinforcing ribs. The plurality of reinforcing ribs are evenly distributed along the circumferential direction of the connecting plate 21, and the middle parts of the plurality of reinforcing ribs intersect, and both ends of each reinforcing rib extend to the edge of the connecting plate 21. With such an arrangement, the cross-shaped reinforcing member 22 can evenly disperse the load to the periphery of the connecting plate 21, avoid local stress concentration, and further increase the strength of the connecting plate 21 to prevent the connecting plate 21 from deforming during the hoisting process.

[0043] Preferably, the reinforcing member 22 includes four reinforcing ribs, and the suspension connection mechanism 2 includes four lifting lugs 23. The four lifting lugs 23 are respectively installed at the four free ends of the reinforcing member 22. With such an arrangement, the load of the simulated rotor is evenly dispersed, and the forces borne by the four lifting lugs 23 are relatively balanced, ensuring the safety during the testing, loading or disassembling of the cylinder 11 of the hydraulic tipping device.

[0044] On the other hand, the present embodiment provides a method for testing a hydraulic tipping device of a wind-assisted rotor. This method for testing a hydraulic tipping device of a wind-assisted rotor is implemented by the above-mentioned testing tooling for a hydraulic tipping device of a wind-assisted rotor. This method for testing a hydraulic tipping device of a wind-assisted rotor sequentially performs hydraulic tipping tests on the 1st to Nth simulated rotors;

[0045] Among them, when performing a hydraulic tipping test on the i-th simulated rotor, if the test is qualified, then continue to perform a hydraulic tipping test on the (i + 1)-th simulated rotor; if the test is unqualified, then stop performing hydraulic tipping tests on the subsequent simulated rotors;

[0046] Performing a hydraulic tipping test on the i-th simulated rotor includes:

[0047] Connect the hoisting equipment to the hoisting mechanism 2 at the top of the i-th simulated rotor, making the i-th simulated rotor in an upright state; under the action of the hydraulic tilting device, tilt the i-th simulated rotor.

[0048] Taking N = 4 as an example, the working principle of the hydraulic tilting device test fixture for the wind-force assisted rotor to replace the wind-force assisted rotor to be tested for tilting test is introduced as follows:

[0049] The hydraulic tilting device test fixture for the wind-force assisted rotor includes a hoisting mechanism 2 and four cylinders 11, namely the first cylinder, the second cylinder, the third cylinder and the fourth cylinder. The simulated rotor is changed from an upright state to a tilted state through the hydraulic tilting device to test the tilting performance of the hydraulic tilting device.

[0050] When using the first type of simulated rotor to test the hydraulic tilting device, first connect the hoisting mechanism 2 to the first cylinder to form the first type of simulated rotor, then connect the lifting lug 23 to the hoisting equipment, lift the first type of simulated rotor in a tilted state to an upright state through the hoisting equipment, and finally start the hydraulic tilting device to tilt the first type of simulated rotor, thus completing the first hydraulic tilting device test.

[0051] When using the second type of simulated rotor to test the hydraulic tilting device, first lift the first type of simulated rotor in a tilted state to an upright state through the hoisting equipment, then remove the hoisting mechanism 2 from the simulated main body part, connect the hoisting mechanism 2 to the second cylinder, lift the second cylinder to an upright state and move it to a position coaxial with the first cylinder, and connect the first cylinder and the second cylinder through bolt-nut cooperation to form the second type of simulated rotor. Finally, start the hydraulic tilting device to tilt the second type of simulated rotor to complete the second hydraulic tilting device test.

[0052] The principle of using the third type of simulated rotor to test the hydraulic tilting device is the same as that of the second type of simulated rotor, and will not be elaborated here in this embodiment.

[0053] When using the fourth type of simulated rotor to test the hydraulic tilting device, first lift the third type of simulated rotor in a tilted state to an upright state through the hoisting equipment, then remove the hoisting mechanism 2 from the simulated main body part, connect the hoisting mechanism 2 to the fourth cylinder, lift the fourth cylinder to an upright state and move it to a position coaxial with the third cylinder, and connect the lower flange 1112 of the fourth cylinder and the upper flange 1111 of the third cylinder through bolt-nut cooperation to form the fourth type of simulated rotor. Start the hydraulic tilting device to tilt the fourth type of simulated rotor to complete the fourth hydraulic tilting device test. At this time, the fourth type of simulated rotor has the weight and center of gravity height of the wind-force assisted rotor to be tested, that is, the load capacity of the hydraulic tilting device can complete the tilting of the wind-force assisted rotor to be tested.

[0054] Subsequently, if you want to test the loading weight limit of the hydraulic tipping device, you can gradually load the movable counterweight 115 to the fourth cylinder and test it through the hydraulic tipping device until the hydraulic tipping device fails. At this time, the weight of the test work is the loading weight limit of the hydraulic tipping device.

[0055] It should be understood that N can be 2, 3, 4..., and N can be an integer not less than 2. This embodiment and the accompanying drawings are only examples.

[0056] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
