Abstract
The invention discloses a high-altitude butt joint device for a fan impeller, which consists of a fixed end, a butt joint end and six servo electric cylinders. The high-altitude butting device for the fan impeller adopts a visual servo technology, the position of the impeller is identified, the posture of the platform is adjusted to be butted with the impeller, and an automatic nut at the butting end locks an impeller hub bolt. And adjusting the posture of the butt joint end of the platform again to enable the impeller and the host to be coaxial, enabling the long bolt of the impeller to enter the flange hole of the host, unlocking the platform, hoisting the platform by the crane auxiliary crane, and butting the impeller with the host under the guidance of the long bolt.
Description
Technical Field
The invention relates to a butt joint device, in particular to a high-altitude butt joint device for a fan impeller.
Background
The existing fan impeller butt joint adopts a mode that a crane is matched with a manual pull rope for adjustment, namely, the crane bears the gravity of the impeller, and the impeller posture is adjusted manually on the ground through pulling, so that the impeller bolt and the fan flange are in butt joint in the air. The butt joint mode is low in control accuracy, the impeller bolt is difficult to enter a flange hole of the host, the impeller and the host are easy to collide, and the butt joint difficulty is greatly improved under the influence of wind.
Disclosure of Invention
In order to overcome the defects of low impeller butt joint precision, high difficulty and high wind influence, the invention provides a six-degree-of-freedom butt joint platform adopting a visual servo technology, which accurately catches an impeller bolt to complete the butt joint of a fan impeller.
The technical scheme adopted by the invention for solving the technical problems is as follows: the fan impeller butt joint platform consists of a fixed end, a butt joint end and six servo electric cylinders and has six degrees of freedom of translation and rotation. The fixed end is fixed on the host, the visual servo technology is adopted in the butt joint process, the position of the impeller is identified, the posture of the platform is adjusted to be in butt joint with the impeller, and the automatic nut at the butt joint end locks the impeller hub bolt. And adjusting the posture of the butt joint end of the platform again to enable the impeller and the host to be coaxial, enabling the long bolt of the impeller to enter the flange hole of the host, unlocking the platform, hoisting by the crane pair, and butting the impeller with the host under the guidance of the long bolt. The response speed of the fan impeller butt joint platform is far higher than the swing of the impeller in wind, the fan impeller butt joint platform can follow the posture of the impeller in real time to position, and the whole-process automation is realized.
The butt joint scheme of the invention does not need to change the structure of the fan impeller, has strong universality and wind interference resistance, can be disassembled after the butt joint of the butt joint platform is finished, has no component residue, can be repeatedly used, and does not influence the operation of the fan.

Detailed Description
A fixed end 7 of a fan impeller butt joint platform is fixedly installed on a flange of a host through a short bolt 5, the host and the platform are simultaneously hoisted and installed to a tower barrel, the crane hoists the impeller to install a long bolt 9, then the impeller is hoisted to a position close to the platform, the butt joint end 1 adjusts the posture of the platform through a visual servo technology, an automatic nut 2 of the butt joint end catches an impeller hub bolt, after butt joint, the automatic nut 2 locks the fan impeller butt joint platform through the automatic nut 2 under the pretension force of a spring 16, the butt joint end position posture of the fan impeller butt joint platform is adjusted, the fixed end is coaxial with the butt joint end, namely the impeller is coaxial with the host, and the long bolt 9 penetrates through a flange hole of the host. The fan impeller docking platform is unlocked by an automatic bolt 6 and opened by two unlocking motors 4, and the platform is hoisted by the auxiliary crane of the crane. The impeller is gradually close to the host flange under the guidance of the long bolts 9, and the long bolts 9 are separated one by one until complete butt joint is achieved.
Claims (2)
1. The utility model provides a fan wheel high altitude interfacing apparatus, includes stiff end, butt joint end, electric putter, characterized by: the CCD camera visually positions the impeller, the butt joint end moves and fixes the impeller bolt through the electric nut, the butt joint end drives the impeller to move to be coaxial with the host, and the long bolt of the impeller enters the host flange.
