Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, and in particular to a special hoisting sling for wind power generation equipment. Background Technology

[0002] In the installation and maintenance of wind power equipment, hoisting is an indispensable key link. Wind power equipment is usually characterized by its large size, heavy weight, and complex structure, and its hoisting process has extremely high requirements for safety and stability.

[0003] Traditional lifting slings have some problems in actual use, especially when lifting large wind power equipment. The upper part of the lifting sling is prone to loosening. This loosening can cause the lifting equipment to shake during the lifting process, which not only affects the accuracy and efficiency of the lifting, but may also cause safety accidents, posing potential risks to construction personnel and equipment, and exacerbating the instability and uncontrollability of the lifting process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a special lifting sling for wind power generation equipment.

[0005] This utility model is achieved using the following technical solution: a special lifting sling for wind power generation equipment, comprising a lifting sling body, a lifting ring provided on the surface of the lifting sling body, a slider one slidably connected to the surface of the lifting sling body, a slider two slidably connected to the surface of the lifting sling body, a limit crossbar fixedly connected to the surface of the slider one, a locking groove and an insertion groove provided on the surface of the slider two, a sleeve fixedly connected to the upper surface of the slider two, a telescopic spring fixedly connected to the inner wall of the sleeve, a tension ring fixedly connected to the lower surface of the telescopic spring, a locking pin fixedly connected to the lower surface of the tension ring, and a lifting block fixedly connected to the upper surface of the tension ring.

[0006] The above technical solution effectively avoids the problem of the upper part of the lifting sling being relatively loose during the lifting process, which can easily lead to the shaking of the lifting equipment. It significantly reduces the sway space of the lifting ring on the surface of the lifting sling, greatly improves the stability and safety of the lifting process, and provides a reliable guarantee for the lifting operation of wind power generation equipment.

[0007] As a further improvement to the above solution, the slider is slidably connected to one side of the surface of the lifting belt.

[0008] As a further improvement to the above solution, the second slider is slidably connected to the other side of the surface of the lifting belt.

[0009] The above technical solutions further improve the stability and safety of the lifting sling during lifting operations, providing a solid guarantee for the safe lifting of wind power generation equipment.

[0010] As a further improvement to the above solution, the limiting crossbar is adapted to the insertion groove.

[0011] The above technical solution not only makes the locking method easy to operate, but also has a significant locking effect, effectively preventing relative sliding between slider one and slider two during the hoisting process and ensuring the stability of the hoisting sling during the hoisting process.

[0012] As a further improvement to the above solution, the locking groove is adapted to the locking pin.

[0013] As a further improvement to the above solution, the locking pin is inserted through the slider and into the inside of the locking groove.

[0014] As a further improvement to the above solution, the material of the lifting sling is nylon fiber.

[0015] Through the aforementioned technical solutions, nylon fibers exhibit extremely high strength, capable of withstanding significant tensile forces. This ensures that the lifting slings will not easily break when lifting heavy objects such as wind turbine equipment, providing reliable protection for the lifting operation. Secondly, nylon fibers possess excellent abrasion resistance, maintaining a long service life during contact and friction with the lifting and wind turbine equipment, reducing the frequency of sling replacements and lowering lifting costs. Furthermore, nylon fibers also possess good flexibility, allowing the lifting sling to be flexibly adjusted according to the shape and lifting angle of the equipment during the lifting process, better conforming to the equipment surface and improving the stability and safety of the lifting operation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a lifting block to raise the tension ring, which in turn compresses the telescopic spring, causing the locking pin to disengage from the insertion groove. Once the limiting crossbar is inserted into the groove, the lifting block is slowly released. Under the restoring force of the telescopic spring, the tension ring descends, causing the locking pin to penetrate the locking groove on the surface of the limiting crossbar, thus achieving a stable lock on slider one and slider two. This effectively avoids the swaying problem caused by the loose upper area of ​​the lifting sling during lifting, as is common with traditional lifting slings. It significantly reduces the swaying space of the lifting ring on the surface of the lifting sling. Simultaneously, the limiting crossbar restricts the swaying of the lifting ring, greatly improving lifting stability and safety, providing strong protection for the safe lifting of wind power equipment, reducing lifting risks, and improving lifting operation efficiency.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4This embodiment describes a special lifting sling for wind power equipment, comprising a lifting sling body 1, a lifting ring 2 on the surface of the lifting sling body 1, a slider 3 slidably connected to the surface of the lifting sling body 1, a slider 4 slidably connected to the surface of the lifting sling body 1, a limit bar 5 fixedly connected to the surface of the slider 3, a locking groove 6 and an insertion groove 7 on the surface of the slider 4, a sleeve 8 fixedly connected to the upper surface of the slider 4, a telescopic spring 9 fixedly connected to the inner wall of the sleeve 8, a tension ring 10 fixedly connected to the lower surface of the telescopic spring 9, a locking pin 11 fixedly connected to the lower surface of the tension ring 10, and a lifting block 12 fixedly connected to the upper surface of the tension ring 10. In use, personnel first tightly connect the wind power equipment to the bolt holes on the surface of the lifting ring 2 using bolts, then connect the lifting sling body 1 to the lifting equipment, and then... When block 3 and slider 4 slide to the bottom, the operator pulls the lifting block 12. The lifting block 12 drives the tension ring 10 to rise and compress the telescopic spring 9. The rise of the tension ring 10 causes the locking pin 11 to disengage from the inside of the insertion groove 7. The operator inserts the limiting crossbar 5 on the surface of slider 3 into the inside of the insertion groove 7. When the limiting crossbar 5 is accurately inserted into place, the operator slowly releases the pulling force on the lifting block 12. Under the action of the return elastic force of the telescopic spring 9, the locking pin 11 passes through the locking groove 6 on the surface of the limiting crossbar 5, firmly fixing the position of the limiting crossbar 5, thereby achieving a stable lock between slider 3 and slider 4. When the positions of slider 3 and slider 4 are locked, the lifting belt body 1 inside slider 3 and slider 4 will fit tightly together. At the same time, the limiting crossbar 5 can effectively limit the positional sway of the lifting ring 2 on the surface of the lifting belt body 1, greatly reducing the amount of sway of the lifting ring 2.

[0027] The slider 3 is slidably connected to one side of the surface of the lifting belt body 1.

[0028] Slider 2 4 is slidably connected to the other side of the surface of the lifting belt body 1.

[0029] The limiting crossbar 5 is adapted to the insertion groove 7. When the limiting crossbar 5 is inserted into the insertion groove 7, the locking pin 11 can accurately penetrate the locking groove 6 on the surface of the limiting crossbar 5, thereby firmly fixing the limiting crossbar 5 in the insertion groove 7. This makes the locking between slider 1 3 and slider 2 4 more stable and reliable, effectively preventing slider 1 3 and slider 2 4 from loosening accidentally during hoisting.

[0030] The locking groove 6 is adapted to the locking pin 11. When the locking pin 11 is inserted into the locking groove 6, the limiting crossbar 5 can be firmly fixed on the slider 2 4, thereby realizing a stable lock between slider 1 3 and slider 2 4.

[0031] The locking pin 11 passes through the slider 2 4 and is inserted into the locking groove 6. Under the elastic force of the telescopic spring 9, the locking pin 11 can accurately pass through the slider 2 4 and be inserted into the locking groove 6, so as to firmly fix the limiting crossbar 5 on the slider 2 4.

[0032] The lifting sling body 1 is made of nylon fiber. Nylon fiber has extremely high strength and can withstand large tensile forces, ensuring that the lifting sling will not easily break when lifting heavy objects such as wind power generation equipment, providing reliable protection for the lifting operation. Secondly, nylon fiber has good wear resistance, which can maintain a long service life during the contact and friction with the lifting equipment and wind power generation equipment during the lifting process, reducing the replacement frequency of the lifting sling and lowering the lifting cost. In addition, nylon fiber also has good flexibility, which allows the lifting sling body 1 to be flexibly adjusted according to the shape of the equipment and the lifting angle during the lifting process, better conforming to the surface of the equipment and improving the stability and safety of the lifting.

[0033] The implementation principle of a special lifting sling for wind power equipment in this embodiment is as follows: First, the operator tightly connects the wind power equipment to the bolt holes on the surface of the lifting ring 2 using bolts, ensuring the stability between the equipment and the lifting sling. Then, the operator connects the lifting sling body 1 to the lifting equipment. Next, the operator slides slider 3 and slider 4 along the surface of the lifting sling body 1 to the bottom. The operator then pulls the lifting block 12, which, under the pulling force, causes the tension ring 10 to rise, thereby compressing the telescopic spring 9. As the tension ring 10 rises, the locking pin 11 disengages from the insertion groove 7. The operator then precisely inserts the limiting crossbar 5 on the surface of slider 3 into the insertion groove 7. Once the limiting crossbar 5 is fully inserted into the insertion groove 7 and accurately positioned, the operator slowly releases the pulling force on the lifting block 12. At this time, under the restoring force of the telescopic spring 9, the lifting sling... As the extension ring 10 descends, it drives the locking pin 11 to accurately penetrate the locking groove 6 on the surface of the limiting crossbar 5, firmly fixing the limiting crossbar 5 in the insertion groove 7. This achieves a stable lock between slider 3 and slider 4. Once the positions of slider 3 and slider 4 are locked, the lifting sling body 1 inside slider 3 and slider 4 will fit tightly together, forming a stable structure. At the same time, the limiting crossbar 5 can effectively limit the positional movement of the lifting ring 2 on the surface of the lifting sling body 1, significantly reducing the amount of shaking of the lifting ring 2, thereby improving the stability and safety of the lifting process. This unique locking structure and operation method effectively avoids the problem that the upper area of ​​the traditional lifting sling is relatively loose during the lifting process, which easily leads to shaking of the lifting equipment. It significantly reduces the shaking space of the lifting ring 2 on the surface of the lifting sling body 1, providing a strong guarantee for the safe lifting of wind power generation equipment.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
