Embodiment

[0021] see Figure 1-2 , the present invention provides the following technical solutions: a wind power generation blade installation barring positioning sensor, including a support seat 6 and a fan blade mounting seat 8, the side of the fan blade mounting seat 8 is fixedly installed with a barring disc 1, and the barring disc 1 There are several connecting holes 2 on the surface of the connecting hole 2, and a swing arm shaft 3 is plugged into one of the connecting holes 2. By setting the connecting hole 2, the connecting hole 2 is aligned with the pin hole on the swing arm 4. By inserting the swing arm shaft 3, The connection between the turning disk 1 and the swing arm 4 can be achieved, and then the purpose of rotating the turning disk 1 can be achieved by means of the hydraulic cylinder 5 stretching and contracting.

[0022] The surface of the swing arm shaft 3 is sleeved with a swing arm 4, and a hydraulic cylinder 5 is movably connected between the surface of the swing ...

Abstract

The invention belongs to the technical field of blade mounting and positioning, and relates to a wind power generation blade mounting jigger positioning sensor. The wind power generation blade mounting jigger positioning sensor comprises a supporting base and a fan blade mounting base, a jigger disc is fixedly arranged on the side surface of the fan blade mounting base, a plurality of connecting holes are formed in the surface of the jigger disc, a swing arm shaft is connected into one connecting hole in an inserted mode, the surface of the swing arm shaft is sleeved with a swing arm, and a hydraulic cylinder is movably connected between the surface of the swing arm and the supporting base through a pin shaft. The wind power generation blade mounting jigger positioning sensor has the beneficial effects that the purpose of driving the jigger disc to rotate through the swing arm and the swing arm shaft can be achieved through the work of the hydraulic cylinder, along with the telescoping of the hydraulic cylinder and by means of the movement effect of the pin shaft, the contact between an induction claw and the connecting hole can be inducted through arrangement of an optical sensor, and therefore whether the connecting hole is aligned with a pin hole in the swing arm can be positioned and judged, and the positioning accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of blade installation and positioning, and in particular relates to a wind power generation blade installation barring positioning sensor. Background technique [0002] With the development of wind power technology, the power of a single wind power generation increases, the length of the blades is also increasing, and the weight of the wind blades is also gradually increasing, so the difficulty of installing the wind blades is also gradually increasing. Generally, the blade installation base of the wind power generator is adjusted to the installation position and then the second blade is installed. Then installing the third blade also needs to adjust the blade base to the installation position for installation. In this way, a turning device is needed to drive the blade mounting seat to rotate so that it rotates to the installation position. Due to the accuracy of position control, a positioning sensor is n...
