Description

Technical Field

[0001] The invention relates to the technical field of bolt sleeve testing, and in particular to testing equipment for wind turbine blade root bolt sleeves. Background Art

[0002] Blades are the most critical components of wind turbines. They are getting longer and heavier. The blades are connected to the hub with bolts. The blade root bolt connection will also be subjected to complex tensile or compressive loads. The bonding force between the bolts and the bolt sleeves becomes particularly important. Pulling out the bolt sleeves or damage to the bolts will cause the connection of the blade root bolts to fail, resulting in serious tower collapse accidents. Therefore, it is necessary to perform a tensile test on the blade root bolt sleeves.

[0003] At present, when testing the blade root bolt sleeve, it is necessary to manually assist in operating other equipment to load the materials, which has low work efficiency. In addition, when the staff fixes the two ends of the bolt sleeve to apply a stable tensile force, additional staff or devices are required to assist in supporting the bolt sleeve to keep it stable so as to fix the two ends of the bolt sleeve. At the same time, the support of the bolt sleeve needs to be removed after the fixing is completed to avoid affecting the subsequent tensile test. The operation is cumbersome, time-consuming and labor-intensive, and it is inconvenient to collect the bolt sleeve after the test. In addition, the existing device is difficult to simulate the impact of different environments on the bolt sleeve test, and has low practicality. Summary of the invention

The sliding block 43 is located in the sliding groove 47 and is slidably connected to the sliding groove 47.

[0032] When the present invention is used, there are enough bolt sleeves stored in the storage box 5, one of which will fall into the feeding chute 41, and the telescopic end of the bolt sleeve will be extended by driving the cylinder 21, and the driving cylinder 21 will drive the second slope block 29 and the two first slope blocks 22 to move. During this movement, the second push rod 31 will first contact the slope surface of one of the first slope blocks 22 and finally move to another plane section. During this process, the second push rod 31 and the first moving plug 34 (attached Figure 4The incompressible fluid in the fourth cylinder 30 located on the right side of the first movable plug 34 will be squeezed into the third cylinder 26 through the second tube 19, thereby making the third movable plug 40, the mounting rod 39 and the movable block 38 (attached Figure 5 ) moves to the left, and by setting a connecting rod 25, the rotating plate 3 can rotate clockwise, so that the rotating plate 3 and the inclined plate 4 form a "V" shape;

[0033] Then the first push rod 28 will contact the slope of the second slope block 29 and finally move to another plane section. In this process, the telescopic rod 23 is extended, the first tension spring 24 is stretched, the cross plate 18, the inclined plate 4 and the rotating plate 3 will move upward, and the inclined plate 4 moves to a position aligned with the lower end of the feeding hole 13. Finally, the third push rod 32 will contact the slope of another first slope block 22 and finally move to another plane section. In this process, the third push rod 32 and the second movable plug 35 will move to the left, and the third tension spring 36 will be stretched, so that the incompressible fluid located on the left side of the second movable plug 35 in the second cylinder 17 will be squeezed into the first cylinder 11 through the first tube 16, so that the fourth movable plug 44, the auxiliary rod 45 and the movable column 46 move straight to the right. In this process, since the movable column 46 will not rotate, the sliding block 43 slides in the arc-shaped sliding groove 47, so that the hollow shaft 10 (attached Figure 6 ) rotate counterclockwise 120 degrees, so that one of the bolt sleeves in the feed chute 41 rotates to the feed hole 13, and finally slides through the feed hole 13 and the inclined plate 4 to the "V" area formed by the inclined plate 4 and the rotating plate 3. At this time, the staff can fix the two ends of the bolt sleeve and finally install it into the two fixtures of the testing machine. Since the hollow shaft 10 is fixedly connected to the inner ring of the one-way bearing 9, when the hollow shaft 10 rotates counterclockwise, the inner ring of the one-way bearing 9 rotates counterclockwise accordingly, but at this time the inner ring and outer ring of the one-way bearing 9 are idling, and the turntable 8 does not rotate;

[0034] After the bolt sleeve is fixed, the telescopic end is retracted by driving the cylinder 21, and the third push rod 32 will contact each other along the slope of the other first slope block 22 again and finally move to the initial plane section. The tension generated by the elongation of the third tension spring 36 can make the third push rod 32 and the second movable plug 35 move to the right, so that the incompressible fluid in the first cylinder 11 is sucked into the second cylinder 17, and the fourth movable plug 44, the auxiliary rod 45 and the movable column 46 move to the left. By setting the sliding block 43 and the sliding groove 47, the hollow shaft 10 can be rotated clockwise. After rotating 120 degrees, the feed chute 41 is changed from the position of the feed hole 13 to the bottom of the storage box 5, and another bolt sleeve falls into the feed chute 41. When the hollow shaft 10 rotates clockwise, the inner ring of the one-way bearing 9 rotates clockwise accordingly. At this time, the inner ring and the outer ring of the one-way bearing 9 are locked, and the turntable 8 rotates clockwise accordingly, so that the hot air blower 14 rotates to the position of the processing hole 7. The cold air blower 15 rotates to the initial position of the hot air blower 14. The hot air blower 14 can pass the processing hole 7 and blow it into another bolt sleeve in the feed chute 41 to heat it.

[0035] Subsequently, the first push rod 28 will contact the slope of the second slope block 29 again and finally move to the initial plane section. The tension generated by the elongation of the first tension spring 24 can make the cross plate, the inclined plate 4 and the rotating plate 3 move downward, so that one of the fixed bolt sleeves is suspended in the air. By applying a stable tension to both ends of one of the bolt sleeves through the testing machine, a tensile test can be performed on it. After the test, the one of the bolt sleeves will be released and fall between the rotating plate 3 and the inclined plate 4. Finally, the second push rod 31 will contact the slope of the first slope block 22 again and finally move to the initial plane section. The tension generated by the elongation of the second tension spring 33 can make the second push rod 31 and the first moving plug 34 move to the left, so that the third cylinder 26 The incompressible fluid inside is sucked into the fourth cylinder 30, and the third movable plug 40, the mounting rod 39 and the movable block 38 move to the right. By setting the connecting rod 25, the rotating plate 3 can rotate counterclockwise, so that the upper surface of the rotating plate 3 is flush with the upper surface of the inclined plate 4, so that one of its bolt sleeves slides along the surface of the inclined plate 4 and the rotating plate 3 to the collecting box 2 for collection, and so on. Another bolt sleeve that has been heat-treated can be fixed, tested and collected, and another bolt sleeve will fall into the discharge chute 41, and the cold air fan 15 will rotate to the processing hole 7 for refrigeration treatment, and finally another bolt sleeve that has been cold-treated can be fixed, tested and collected, simulating the influence of different environments on the bolt sleeve environment, and can perform repeated tests.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
