Embodiment Construction
[0027] The present invention will be further described below in conjunction with accompanying drawing:
[0028] Such as figure 1 with 2 as shown, figure 1 It is a schematic diagram of the use state of the concentric adjustment device of the present invention, figure 2 It is a schematic view of another angle of use of the concentric adjustment device of the present invention. The concentric adjustment device includes a reference frame 1 installed on the outer plane of the pitch bearing 8 and a comparison frame 2 abutted against the inner wall of the blade hole of the spinner 7 .
[0029] Such as image 3 Shown is a schematic diagram of the structure of the reference frame 1. The reference frame 1 includes a reference rod 3 flatly attached to the outer plane of the pitch bearing 8 and a laser pointer 4 fixed on the reference rod 3 . The laser pointer 4 is vertically arranged on the reference rod 3 along the axial direction of the pitch bearing 8 , and the emitting light p...

The invention belongs to the field of wind turbine generator system wind wheel assemblies, and particularly relates to a concentric adjustment device for a blade hole of a flow guide cover of a wind turbine generator and an annular hole of a variable-pitch bearing. The concentric adjustment device comprises a reference frame and a contrast frame. The reference frame comprises a reference rod horizontally attached to the outer plane of the variable-pitch bearing, and a laser pen fixed to the reference rod. The laser pen is perpendicularly arranged on the reference rod in the axis direction of the variable-pitch bearing. The emitting light point of the laser pen is located on the axis of the variable-pitch bearing. The contrast frame comprises a bottom frame connected to the inner wall face of the blade hole of the flow guide cover in an abutting manner, and a mark indication plate arranged on the bottom frame. The marker indication plate is located at the center of the blade hole of the flow guide cover, and provided with an area used for displaying the allowable deviation of the emitting light point of the laser pen. By means of the concentric adjustment device, repeated work of workers can be reduced, concentric adjustment of the blade hole and the variable-pitch bearing is conducted through one step, the radial size does not need to be measured, and assembly of the flow guide cover and a hub is rapidly and accurately completed.
Description
technical field [0001] The invention belongs to the field of assembly of wind wheel components of wind power generating sets, and in particular relates to a concentric adjustment device for blade holes of wind turbine shrouds and pitch bearing ring holes. Background technique [0002] In the assembly of the spinner and the hub of the wind wheel assembly, considering the insufficient structural rigidity of the FRP material, it is necessary to measure the radial direction from the upper ring hole of the pitch bearing to the inner circular surface of the spinner blade hole at the same time as the installation and connection. distance, and constantly adjust to ensure that the ring hole of the pitch bearing is concentric with the hole of the blade, which is extremely time-consuming in assembly, and there is too much repetitive work. inconvenient. Contents of the invention [0003] The purpose of the present invention is to provide a method that can reduce the repetitive labor ...
