Embodiment 1

[0032] Embodiment 1: as figure 1 , figure 2 As shown, the present invention includes a variable diameter attachment device 5, a wheel mechanism 3, a pulley block hanger 7, a working platform 2 and a rotatable lifting mechanism 12, and one end of the working platform 2 is connected with a variable diameter attachment fixedly connected with the tower. Mechanism, the side working platform 2 is also connected with an extendable or retractable wheel mechanism 3 for supporting on the tower 4, the pulley block hanger 2 is fixed on the fan nacelle 8, through the roll on the working platform 2 The drum mechanism wire rope is connected to the working platform 2 to realize the rising and falling of the working platform 2, and the rotatable lifting mechanism 12 for hanging parts is fixed on the working platform 2.

[0033] like figure 1 As shown, the working platform 2 is an "L"-shaped frame structure, forming an upper and lower two-layer frame, one end of the two-layer frame is close ...

Embodiment 2

[0045] Embodiment 2: The difference between this example and Embodiment 1 is that the inter-arm telescopic mechanism 53 includes an electric push rod and a fixed ear plate 532, that is, the electric push rod replaces the hydraulic cylinder I 531, and the two ends of the electric push rod pass through the fixed ears respectively. The plate 532 is connected to two adjacent connecting arms 58 , and the pushing out or retracting of the electric push rod adjusts the opening or buckling of the connecting arms 58 . The hydraulic oil cylinder II59 of the variable diameter attachment mechanism 51 can also be replaced by an electric push rod.

Abstract

The invention discloses a traction attached type fan maintenance hoisting platform, belonging to the technical field of fans. The traction attached type fan maintenance hoisting platform comprises a reducing attachment device, a depended wheel mechanism, a pulley block hanging bracket, a working platform and a rotatable hoisting mechanism, wherein one end of the working platform is connected with the reducing attachment mechanism fixedly connected with a tower tube, the working platform is also connected with the retractable depended wheel mechanism used for supporting the tower tube, the pulley block hanging bracket is fixed on a fan cabin, and connected with the working platform through a coiling drum steel wire rope on the working platform so as to realize the lifting and descending of the working platform; the rotatable hoisting mechanism for hanging the parts is fixed on the working platform. The hoisting platform disclosed by the invention can be lifted and can descend, the climbing synchronism and the security are good, the whole machine is stable, the assembling/disassembling and the operation are convenient; the hosting platform is suitable for maintaining and repairing outer vertical faces of various wind driven generator tower drums, cabin outer surfaces and fan blades.

Description

technical field [0001] The invention relates to a traction-attached fan maintenance lifting platform. In particular, it relates to a working platform that is used in the maintenance and lifting operations of components in the nacelle of various wind-driven generators, and depends on the hoisting and lifting of steel wire ropes, and relies on the working platform attached to the outer facade of the wind-driven generator tower when hoisting. Background technique [0002] With the shortage of energy, wind power generators are developing rapidly. There is a lack of special construction equipment for the maintenance of the inside and outside of the ultra-high large-scale wind turbine tower, the nacelle and the blades. A large number of imported equipment is used in the construction, or replaced by traditional construction equipment with a low safety factor and low work efficiency, which seriously affects my country's ultra-high The improvement of the technical level of constructi...
