Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal nuts, in particular to a heavy hexagonal nut for wind power generation. Background Art

[0002] A wind turbine generator set is composed of components such as a fuselage tower and wings. It is an electrical equipment that can convert wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] When the existing wind turbine fuselage tower is installed on the ground, the fuselage tower is hoisted and connected to the prefabricated bolts on the bottom support, and then threadedly fixed with a large heavy hexagonal nut to ensure the stability of the fuselage tower. The nut is fixed to each other by the bite friction between the internal thread and the bolt assembly. When the shear force of the nut is overloaded, the inner thread of the nut is easily squeezed and deformed, which may seriously cause the nut to crack. As a result, when the nut needs to be maintained and replaced later, the nut is difficult to disassemble and replace after being overloaded and deformed. For this reason, we propose a heavy hexagonal nut for wind power generation. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a heavy hexagonal nut for wind power generation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heavy-duty hexagonal nut for wind power generation, comprising a supporting base, a prefabricated bolt and a wind turbine body, the bottom of the wind turbine body is provided with an installation groove for docking with the prefabricated bolt, the external thread of the prefabricated bolt is installed with two groups of assembled hexagonal nut assemblies, the bottom of the hexagonal nut assembly is installed with a nut base, the two groups of nut bases are spliced ​​into a hexagonal structure, and the outside of the two groups of hexagonal nut assemblies is provided with a hexagonal hoop sleeve for fastening the hexagonal nut assembly.

[0007] Furthermore, after the two groups of hexagonal nut assemblies are connected and assembled with each other through the docking grooves and the docking parts, when the hexagonal hoop is mounted on the outside of the two groups of hexagonal nut assemblies, the hexagonal hoop is limitedly engaged with the slot on the outside of the hexagonal nut assembly through the plug-in, and the hexagonal hoop is located outside the two groups of hexagonal nut assemblies in a tightened state.

[0008] Preferably, the four side surfaces of the interior of the hexagonal hoop are equipped with plug-ins, the inner surface of the hexagonal hoop is provided with a buffer pad covering the outside of the plug-in, and the periphery of each group of the hexagonal nut components is provided with slots on both sides;

[0009] Furthermore, the buffer pad itself has a deformation property, and the inner side of the hexagonal hoop is in a mutually fitting and extruded state with the outer sides of the two groups of hexagonal nut assemblies through the buffer pad.

[0010] Preferably, a reinforcement screw sleeve assembly is provided on the top of the hexagonal hoop, and the reinforcement screw sleeve assembly includes a reinforcement upper part and a reinforcement lower part integrally formed with the reinforcement upper part;

[0011] Furthermore, the reinforced upper part is threadedly connected to the external thread of the prefabricated bolt, and the reinforced lower part is threadedly connected to the reinforcing screw groove inside the hexagonal hoop. The reinforcing screw sleeve assembly is threadedly engaged with the prefabricated bolt and the hexagonal hoop.

[0012] Beneficial Effects

[0013] The utility model provides a heavy hexagonal nut for wind power generation, which has the following beneficial effects:

[0014] (1) A heavy hexagonal nut for wind power generation. In this article, after the wind turbine body is initially installed and docked with the prefabricated bolts through the installation groove, the two groups of hexagonal nut assemblies can be sleeved on the outside of the prefabricated bolts to make them docked with each other and limited. The assembled hexagonal nut assemblies are rotated to the bottom of the wind turbine body. At this time, the hexagonal hoop is sleeved on the outside of the two groups of hexagonal nut assemblies through the corresponding slot position of the plug-in, so that the two groups of hexagonal nut assemblies are tightened and reinforced. The inner side of the hexagonal hoop can first be pressed against the outer periphery of the two groups of hexagonal nut assemblies through the provided buffer pad, so as to increase the stability between the hexagonal hoop and the two groups of hexagonal nut assemblies. A nut base is integrally formed at the bottom of the hexagonal nut assembly, and the larger support area of ​​the nut base itself can provide greater support force for the hexagonal nut assembly. When the hexagonal nut assembly needs to be replaced and maintained later, the hexagonal hoop can be removed upwards, so that the two groups of hexagonal nut assemblies can be separated from each other to complete the disassembly and replacement, thereby achieving the effect of facilitating the quick replacement and use of damaged and deformed hexagonal nut assemblies.

[0015] (2) In the heavy hexagonal nut for wind power generation, after the two sets of hexagonal nut assemblies are assembled together on the outside of the prefabricated bolt, they can be sleeved for secondary reinforcement through the hexagonal hoop. At this time, the reinforcement screw sleeve assembly can be threadedly connected to the outer surface of the prefabricated bolt, so that the reinforcement lower part is threadedly connected to the reinforcement screw groove inside the hexagonal hoop, and the reinforcement upper part is threadedly connected to the outer surface of the prefabricated bolt. At this time, the reinforcement screw sleeve assembly can simultaneously engage and limit the hexagonal hoop and the hexagonal nut assembly with each other, thereby achieving the effect of improving the support stability of the wind turbine body itself.
