Description

Technical Field

[0001] The utility model relates to the technical field of wind power construction, in particular to a hoisting auxiliary reinforcement device for wind power construction. Background Art

[0002] During wind turbine construction, scaffolding is essential for installing the nacelle and impeller. For large nacelles or impeller assemblies, scaffolding provides a temporary support structure, assisting in positioning and securing equipment.

[0003] The patent with the current announcement number CN221321692U discloses a hoisting construction scaffold for construction engineering, including a structural beam, a steel plate provided on one side of the structural beam, an I-beam provided on one side of the steel plate, two reinforcing nuts provided on one side of the steel plate, the two reinforcing nuts provided on both sides of the I-beam, two reinforcing bolts provided on the inner side of the structural beam, the two reinforcing bolts movably penetrate the steel plate and are threadedly connected to the two reinforcing nuts, and the bottom of the I-beam is connected to two lower vertical poles. The above technology is provided with a pre-buried bolt ring, an adjustable flange and a diagonal tie rod. When in use, the I-beam is hoisted on one side of the structural beam through the diagonal tie rod, the two ends of the diagonal tie rod are fixed by the pre-buried bolt ring, and the connection strength of the diagonal tie rod is increased by the adjustable flange, thereby improving the stability of the I-beam and preventing its deformation, while improving the overall stability of the scaffolding and ensuring the safety of construction workers.

[0004] However, the above technology still has the following problems:

[0005] During the installation of large nacelles or impeller assemblies, temporary support platforms constructed with scaffolding assist in positioning and securing the equipment. Scaffolding is used to secure guide wind ropes during nacelle hoisting, adjust equipment angles, and ensure installation accuracy. During this process, due to the heavy mass of large nacelles or impeller assemblies, they experience large swings during hoisting. Traditional scaffolding only provides a static platform and cannot dynamically offset the impact of the load. Consequently, it is easy for the scaffolding to fail to support the weight of the nacelle or impeller, resulting in damage and causing the nacelle or impeller to topple over. Utility Model Content

[0006] In view of the deficiencies of the existing technology, the utility model provides a hoisting auxiliary reinforcement device for wind power construction, which can provide auxiliary support during the installation of the nacelle or impeller assembly to reduce damage to the equipment.

[0007] The utility model provides the following technical solutions: a hoisting auxiliary reinforcement device for wind power construction, comprising a scaffolding main body, a round tube being slidably connected to the scaffolding main body, a disc being fixedly connected to the lower end of the round tube, a fixing mechanism being detachably connected to the round tube, a diagonal support rod being fixedly connected to the fixing mechanism, a rotating shaft being fixedly connected to the front end of the diagonal support rod, rotating blocks being rotatably connected to both ends of the rotating shaft, the lower ends of the two rotating blocks being commonly connected to a base plate, a guide mechanism being fixedly connected to the base plate, a cutting mechanism being detachably connected to the guide mechanism, and a lifting assembly being connected to both the guide mechanism and the cutting mechanism.

[0008] Furthermore, the fixing mechanism includes two arc-shaped plates, one and two, which are adapted to the scaffolding main body. Both sides of the arc-shaped plate one are fixedly connected to the support plate one, and both sides of the arc-shaped plate two are fixedly connected to the support plate two. Circular holes are provided on the support plate one and the support plate two, and the support plate one and the support plate two are connected by bolts and nuts.

[0009] Furthermore, the inner walls of the arc-shaped plate 1 and the arc-shaped plate 2 are connected with arc-shaped rubber pads.

[0010] Furthermore, the guide mechanism includes a limiting tube fixedly connected to the base plate, the lower end of the limiting tube passes through the lower surface of the base plate, the upper end of the limiting tube is fixedly connected to an annular plate, and both sides of the annular plate are fixedly connected to a hanging ring.

[0011] Furthermore, the annular plate is provided with a plurality of support blocks in a circumferential array.

[0012] Furthermore, the cutting mechanism includes an inserting rod adapted to the limiting tube, the upper end of the inserting rod is fixedly connected to a knocking block, and both sides of the knocking block are fixedly connected to a second hanging ring.

[0013] Furthermore, the lifting assembly includes a sling, both ends of the sling are fixedly connected with a ring, and the ring is sleeved on the hanging ring second.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of hoisting auxiliary reinforcement device for wind power construction can increase the contact area between the scaffolding body and the ground. The increase in contact area can increase the anti-overturning moment and reduce local stress concentration, preventing the scaffolding from single-point overload failure. At the same time, it directly reduces the pressure per unit area of the ground, avoiding foundation settlement or collapse. Moreover, when the scaffolding is subjected to lateral force, part of the lateral force can be transferred to the ground, reducing the burden on the scaffolding itself and avoiding structural damage caused by local stress concentration, thereby further ensuring the safety of the equipment.

[0020] 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 only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 3 A hoisting auxiliary reinforcement device for wind power construction comprises a scaffolding main body 1, a round tube 2 is slidably connected to the scaffolding main body 1, a disc 3 is fixedly connected to the lower end of the round tube 2, a fixing mechanism is detachably connected to the round tube 2, a diagonal brace 4 is fixedly connected to the fixing mechanism, a rotating shaft 5 is fixedly connected to the front end of the diagonal brace 4, both ends of the rotating shaft 5 are rotatably connected to rotating blocks 6, the lower ends of the two rotating blocks 6 are commonly connected to a base plate 7, a guide mechanism is fixedly connected to the base plate 7, a cutting mechanism is detachably connected to the guide mechanism, and a lifting assembly is connected to both the guide mechanism and the cutting mechanism.

[0022] The hoisting auxiliary reinforcement device for wind power construction in the present invention is similar to the existing hoisting construction scaffolding structure for construction engineering, such as the patent with announcement number CN221321692U which discloses a hoisting construction scaffolding for construction engineering. The main improvement of the present invention is that the bearing capacity of the scaffolding is improved by increasing the contact area between the scaffolding and the ground and by diagonally bracing one side of the scaffolding body 1. Figures 1 to 3As shown, when the hoisting auxiliary reinforcement device for wind power construction in the present invention is used, the disc 3 is placed on the ground, and then the vertical pole on the scaffolding body 1 is placed in the circular tube 2, and the other parts of the scaffolding body 1 are connected to make a temporary support platform for the cabin and the impeller, and then the fixing mechanism is fixed on the vertical pole of the scaffolding body 1, the bottom plate 7 is placed on the ground, and then the cutting mechanism is transported to the guide mechanism, and the cutting mechanism is driven into the ground by a pile driver, thereby fixing the bottom plate 7, so that the position of the diagonal support rod 4 is kept inconvenient, and the scaffolding body 1 is inconvenient. Auxiliary support is provided on one side to strengthen the strength of the scaffolding body 1. Through this operation, the contact area between the scaffolding body 1 and the ground can be increased. The increase in contact area can increase the anti-overturning moment and reduce local stress concentration to prevent the scaffolding from single-point overload failure. At the same time, it directly reduces the pressure per unit area of the ground to avoid foundation settlement or collapse. Moreover, when the scaffolding is subjected to lateral force, part of the lateral force can be transferred to the ground to reduce the burden on the scaffolding itself and avoid structural damage caused by local stress concentration, thereby further ensuring the safety of the equipment.

[0023] like Figure 3 As shown, the fixing mechanism includes two arc-shaped plates 1 8 and 2 9 adapted to the scaffolding body 1 , both sides of the arc-shaped plate 1 8 are fixedly connected with support plates 10 , and both sides of the arc-shaped plate 2 9 are fixedly connected with support plates 2 11 , and circular holes are provided on support plates 10 and 11 , and support plates 10 and 11 are connected by bolts and nuts.

[0024] Specifically, the arc plate 1 8 is placed on one side of the scaffolding body 1 and is attached to it. The height is adjusted so that the bottom plate 7 can be attached to the ground. The arc plate 2 9 is then placed on the other side of the scaffolding body 1 so that the arc plate 2 9 and the arc plate 1 8 are combined together, so that the support plate 10 and the support plate 2 11 can be fixed with bolts and nuts to fix the position of the diagonal brace 4.

[0025] like Figure 3 As shown, the inner walls of the arc-shaped plate 1 8 and the arc-shaped plate 2 9 are connected with arc-shaped rubber pads.

[0026] Specifically, the arc-shaped rubber pad can be fixedly connected to the surface of the arc-shaped plate 1 8 and the arc-shaped plate 2 9, or it can be not fixedly connected. The arc-shaped rubber pad can increase the friction between the arc-shaped plate 1 8 and the arc-shaped plate 2 9 and the scaffolding body 1, thereby enhancing the fixing effect and making it less likely to slide.

[0027] like Figure 1As shown, the guide mechanism includes a limiting tube 12 fixedly connected to the base plate 7, the lower end of the limiting tube 12 passes through the lower surface of the base plate 7, the upper end of the limiting tube 12 is fixedly connected to an annular plate 13, and both sides of the annular plate 13 are fixedly connected to a hanging ring 14.

[0028] Specifically, the hanging ring 14 is used to connect with the lifting assembly, so as to facilitate the adjustment of the guide mechanism and the diagonal support rod 4, etc. The limiting tube 12 is used to limit the direction of the cutting mechanism, and the annular plate 13 is used to support the cutting mechanism.

[0029] like Figure 1 As shown, a plurality of support blocks 15 are arranged in a circumferential array on the annular plate 13 .

[0030] Specifically, the support block 15 can leave a gap between the cutting mechanism and the annular plate 13, so that the cutting mechanism can be lifted and taken out from the ground using other equipment.

[0031] like Figure 2 As shown, the cutting mechanism includes an inserting rod 16 adapted to the limiting tube 12, the upper end of the inserting rod 16 is fixedly connected to a knocking block 17, and both sides of the knocking block 17 are fixedly connected to a hanging ring 18.

[0032] Specifically, the lifting assembly is lifted and moved by the hook, so that the insertion rod 16 is slowly sent into the interior of the limiting tube 12, and the pile driver is used to hit the knocking block 17 to drive the insertion rod 16 into the ground until the knocking block 17 and the support block 15 are abutted, thereby fixing the base plate 7, so that the diagonal support rod 4 is fixed, and is used to support and reinforce the side of the scaffolding body 1, making the scaffolding body 1 more stable, and providing better support for the cabin and impeller, and not prone to damage.

[0033] like Figure 2 As shown, the lifting assembly includes a sling 19 , both ends of the sling 19 are fixedly connected with a ring 20 , and the ring 20 is sleeved on the hanging ring 18 .

[0034] Specifically, the sling 19 can be lifted by using a hook on a crane, thereby facilitating the transfer of the guide mechanism or the implantation mechanism.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
