Embodiment

[0023] like figure 1 , figure 2 and image 3 As shown, a wind wheel installation platform of the present invention includes a circular support tube 1 vertically placed on the ground, with two manholes 9 on the side wall of the support tube 1, and the two ends of the support tube 1 are respectively The hub support 7 and the base 6 are coaxially installed by bolts. On the outer end surface of the hub support 7, there are several hub positioning holes 8 that match with the mounting holes on the hub of the wind wheel along the circumferential direction. On the support tube 1 The rotating bearing 5 is coaxially clamped and installed between the end surface and the hub support 7, and the rotating bearing 5 is also coaxially clamped and installed between the lower end surface and the base 6. The rolling bearing 5 is supported between the hub support 7 and the end surface of the support cylinder 1 and the base. 6 and the end surface of the support cylinder 1, the inner side end of ...

Abstract

The invention discloses a wind wheel installation platform. The wind wheel installation platform is simple in structure and enables the assembly of a wind wheel to be easy, labor-saving, convenient, quick, small in space occupied during the assembly process, and low in cost for flexible use of a wind generating set. The technical problem that wind wheel assembly in the prior art requires at leasttwo cranes, the occupied area is large, the assembly cost is high, and the efficiency is low are solved. The wind wheel installation platform includes supporting cylinders that are mutually matched and supported on the end surface of a wind wheel hub, left supporting arms and right supporting arms are rotatably connected onto the supporting cylinders, the left supporting arm and the right supporting arm are supported on the ground by lifting adjustment rods correspondingly, and the center of gravity projection of the wind wheel hub is located within an acute angle included angle range formed by the left supporting arm and the right supporting arm.

Description

technical field [0001] The invention relates to a wind wheel installation platform, in particular to a wind wheel installation platform which makes the assembly of the wind wheel easy, labor-saving, convenient and fast, and occupies a small space during the assembly process and is low in cost. Background technique [0002] In the current wind turbine assembly process, due to the weight and external dimensions of related components, the wind wheel assembly is generally assembled on site. The common wind rotor assembly assembly process is generally: first place the hub assembly on the ground, then use a main crane to hoist one blade to the pitch bearing installation end face of the hub assembly for assembly, the second and third blades Sequential assembly is carried out in this way. However, after the first blade is installed on the hub assembly, the center of gravity of the hub assembly with the blade will exceed the original fulcrum position, that is, its center of gravity h...
