Description

Technical Field

[0001] This utility model relates to the field of wind power construction technology, and in particular to a hoisting auxiliary reinforcement device for wind power construction. Background Technology

[0002] In the construction of wind power equipment, due to the large overall size of the wind turbine, especially the massive size of the non-disassembled blades, large cranes and lifting beams are required for hoisting operations. Existing lifting beams typically have a simple structure, and hoisting is achieved simply by tying the lifting ropes at the bottom of the beam to the outside of the load. This can easily lead to the lifting ropes causing the load to sway, resulting in imbalance during hoisting and affecting efficiency and safety. Therefore, there is an urgent need for a hoisting auxiliary reinforcement device for wind power construction that reduces the probability of swaying during hoisting and improves the balance of the hoisting process. Utility Model Content

[0003] The purpose of this invention is to provide a hoisting auxiliary reinforcement device for wind power construction, which can reduce the probability of the hoisted parts swaying with the hoisting rope, improve the balance during hoisting, ensure the stability during hoisting, and thus improve hoisting efficiency and increase hoisting safety.

[0004] The present invention adopts the following technical solution: A hoisting auxiliary reinforcement device for wind power construction includes a hoisting beam with tension ropes at both ends of the top. Hoisting ropes are also provided at both ends of the bottom of the hoisting beam, with each end of the hoisting rope connected to the hoisting beam to form a loop structure. Support beams are also provided at both ends of the bottom of the hoisting beam via steel wire ropes. During operation, each support beam is arranged perpendicular to the hoisting beam, located within the loop structure, and its ends abut against both sides of the loop structure.

[0005] Preferably, the support beam has limit grooves at both ends, and during operation, the hoisting ropes on both sides of the ring structure are respectively located in the limit grooves at the corresponding ends.

[0006] Preferably, at least one end of the hoisting rope is detachably connected to the hoisting beam.

[0007] Preferably, both sides of the bottom of the lifting beam are movably provided with take-up rollers, the lifting rope is wound on the take-up rollers, the end of the take-up roller is provided with a positioning groove, and the free end of the lifting rope is provided with a positioning pin; when the positioning pin passes into the positioning groove, the installation of the lifting rope and the positioning of the take-up roller are completed simultaneously.

[0008] Preferably, the bottom of the hoisting beam is provided with an mounting plate, and the winding roller is rotatably mounted on the mounting plate; wherein the mounting plate has a through hole that communicates with the positioning groove; the free end of the hoisting rope is provided with a positioning seat, and the positioning pin is movably mounted on the positioning seat.

[0009] Preferably, the positioning pin is elastically disposed on the positioning seat.

[0010] Preferably, the take-up roller is elastically disposed on the mounting plate along the circumferential direction.

[0011] Preferably, the positioning groove and the positioning pin have non-circular cross-sections.

[0013] Preferably, the mounting plate is provided with a support rod at its bottom, and the support beam is provided with steel wire ropes at both ends, with the end of the steel wire rope away from the support beam fixed to the support rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the lifting rope as a loop structure, it can be sleeved on the outside of the lifting component and supported by the support beam set at the bottom of the lifting beam. This can spread the lifting rope above the lifting component on each side. At this time, the lifting rope on each side, together with the support beam, forms a triangular structure, which effectively improves the balance of the lifting component, reduces the probability of the lifting component swaying with the lifting rope, and improves the safety of lifting. At the same time, spreading the lifting rope by the support beam can reduce the wear between the lifting rope and the lifting component during the lifting process. Spreading the lifting rope also helps to reduce the lifting height and improve the lifting efficiency. Attached Figure Description

[0016] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 3As shown, the wind power construction hoisting auxiliary reinforcement device of this utility model includes a hoisting beam 1. Both ends of the top of the hoisting beam 1 are equipped with traction ropes 2, which are connected to the hooks of the hoisting equipment, forming a triangular structure to enhance stability during hoisting. Both ends of the bottom of the hoisting beam 1 are equipped with hoisting ropes 3, with both ends of each hoisting rope 3 connected to the hoisting beam 1 to form a loop structure. The cavity in the middle of the loop structure forms a space for the hoisting component to pass through and be placed. At least one end of the hoisting rope 3 is detachably connected to the hoisting beam 1 so that the hoisting rope 3 can wrap around the bottom of the hoisting component to form a loop structure and be fitted over the outside of the hoisting component. Support beams 5 are also installed at both ends of the bottom of the lifting beam 1 via steel wire ropes 4. During operation, each support beam 5 is arranged perpendicular to the lifting beam 1 and is located inside the ring structure. Its two ends abut against the two sides of the ring structure, spreading the lifting ropes 3 on both sides of the ring structure. At this time, the support beams 5 on both sides cooperate with the corresponding lifting ropes 3 to form a triangular structure, which effectively improves the balance of the lifting component, reduces the probability of the lifting component swaying with the lifting ropes, and also balances the force on the lifting equipment to a certain extent, improving the safety of the lifting. The support beams 5 spreading the lifting ropes 3 also reduces the lifting height to a certain extent, improving the lifting efficiency.

[0017] Furthermore, limit grooves 6 are provided at both ends of the support beam 5. During operation, the hoisting ropes 3 on both sides of the ring structure are located in the limit grooves 6 at the corresponding ends to prevent the hoisting ropes 3 from detaching from the support beam 5 and causing imbalance during hoisting.

[0018] Furthermore, take-up rollers 7 are movably installed on both sides of the bottom of the lifting beam 1. One end of the lifting rope 3 is wound around the take-up roller 7, and a positioning groove is provided at the end of the take-up roller 7. A positioning pin 8 is provided at the free end of the lifting rope 3. When the positioning pin 8 passes into the positioning groove, the installation of the lifting rope 3 is completed. At this time, the lifting rope 3 forms a loop structure around the outside of the lifting component. Due to the placement of the positioning pin 8, the take-up roller 7 is also positioned, ensuring the stability of the lifting rope 3 during the lifting process. The winding of the lifting rope 3 around the take-up roller 7 helps to adjust the length of the lifting rope 3 according to different lifting components, ensuring that the support beam 5 is always in a suitable position between the lifting component and the lifting beam 1. In this embodiment, the positioning pin 8 matches the shape of the positioning groove. The cross-section of the positioning pin 8 is a non-circular structure, specifically a triangular, rectangular, or cross-shaped structure, to ensure that the positioning pin 8 forms a stable position for the take-up roller 7 after passing into the positioning groove.

[0019] Specifically, a mounting plate 9 is provided at the bottom of the lifting beam 1, and a winding roller 7 is rotatably mounted on the mounting plate 9; a through hole 15 communicating with the positioning groove is provided through the mounting plate 9; a positioning seat 10 is provided at the free end of the lifting rope 3, and a positioning pin 8 is movably mounted on the positioning seat 10. Preferably, the positioning pin 8 is elastically connected to the positioning seat 10 by a spring 11, which can prevent the positioning pin 8 from falling off and being lost from the positioning seat 10, and can also ensure the stability of the positioning pin 8 after positioning, thus ensuring the positioning effect. In addition, in this embodiment, the winding roller 7 is elastically rotatably mounted on the mounting plate 9 in the circumferential direction, which can ensure the automatic winding and reset of the lifting rope 3 after the lifting is completed; the winding roller 7 can be connected to the mounting plate 9 by a spring 11 to realize the free stretching and winding of the lifting rope 3.

[0020] Furthermore, the length of the support beam 5 in this embodiment is adjustable to accommodate lifting components of different widths. The support beam 5 can adopt a two-section structure with a centrally split design. One section is equipped with an extension rod, and the corresponding section has a cavity for the extension rod to pass through. A fixing bolt 12 is installed on the section of the support beam 5 with the cavity to position the adjusted support beam 5. Additionally, a support rod 13 is provided at the bottom of the mounting plate 9 in this embodiment. Steel wire ropes 4 are installed at both ends of the support beam 5, and the steel wire ropes 4 are connected to ear plates 14 located at the top of the support beam 5. The end of the steel wire rope 4 furthest from the support beam 5 is fixed to the support rod 13. The steel wire ropes 4 on both sides form a triangular structure with the support beam 5, ensuring the stability of the support beam 5. Since the length of the support beam 5 in this application is adjustable, different lengths of steel wire ropes 4 can be replaced after the length of the support beam 5 is adjusted, or the ear plates 14 can be slidably adjusted on the support beam 5 to meet the height requirements of the support beam 5. When the ear plate 14 is adjustable, a fixing sleeve can be set at the bottom of the ear plate 14. The fixing sleeve is not shown in the figure. The fixing sleeve is fitted on the support beam 5. As the length of the support beam 5 is adjusted, the fixing sleeve will slide on the support beam 5. After sliding into place, the fixing sleeve can be positioned and fixed by bolts.

[0021] In use, this utility model first involves wrapping the free end of the lifting rope 3 around the bottom of the lifting component, then inserting the positioning pin 8 into the positioning groove, thus completing the installation of the lifting rope 3 on the outside of the lifting component; finally, the support beam 5 is placed within the loop structure formed by the corresponding side of the lifting rope 3, and the lifting rope 3 is placed in the limiting groove 6 to perform the lifting operation. The structure is simple, the operation is convenient and quick, and it is highly practical.
