The specific embodiment
As shown in Figure 1, Figure 2, the patent wind-powered electricity generation maintenance lifting platform of the present invention shown in Fig. 3, Fig. 4, Fig. 5, it comprises: clamp hook 1, clamping piece 2, hydraulic actuating cylinder connects pin block 3, clamping hydraulic cylinder 4, support roller 5, rolling wheel support 6, platform framework 7, revolution supports 8, luffing hydraulic actuating cylinder 9, hydraulic actuating cylinder connects pin plate 10, and clamp arm connects pin plate 11, clamp arm connecting pin 12, clamp arm 13, roller pole 14, support roller hydraulic actuating cylinder 15,, hanger 16, arm 17.Its clamping mechanism comprises two-layer up and down, every layer has 5 joint clamp arms, each saves and between clamp arm 13, by clamp arm, connects pin plate 11 and be connected with clamp arm connecting pin 12, clamp arm connects pin plate 11 and is welded and fixed with clamp arm 13, each saves between clamp arm and can rotate, clamping hydraulic cylinder 9 one end connect pin plate 11 by hydraulic actuating cylinder and are fixed on a joint clamp arm, and the other end connects pin block 3 by hydraulic actuating cylinder and is fixed on another joint clamp arm.Clamp hook 1 and clamping piece 2 are welded and fixed with clamp arm respectively.Roller pole 14 one end are articulated with on first segment clamp arm 13, rotatable.Support roller hydraulic actuating cylinder 15 one end and platform framework 7 are articulated and connected, and the other end is articulated with on roller pole 14, and roller pole 14 bottoms are connected with rolling wheel support 6, and support roller 5 is installed on rolling wheel support 6.Clamping mechanism is connected by Plate Welding with platform framework 7, and platform framework 7 bottom supporting parts are formed by many Plate Weldings, and both sides are welded with guardrail.Platform framework 7 both sides are respectively welded with two hangers 16, totally four.Revolution is supported 8 and is fixed on platform framework 7, top carrying arm 17.The folding arm form that described arm (17) is comprised of five joint telescopic booms.
During concrete use, steel rope strides across the pulley that is fixed on tower cylinder top, and one end is connected on winch, and the other end is connected with the hanger 16 on wind-powered electricity generation maintenance platform platform framework 7, and wind-powered electricity generation keeps in repair hanging of lifting platform and rises power and provided by winch.Before hoisting, the clamping hydraulic cylinder 4 of wind-powered electricity generation maintenance lifting platform clamping mechanism is retracted, the open-shaped state of clamping mechanism.Support roller hydraulic actuating cylinder 15 stretches out, and support roller 5 is attached on tower barrel.Start winch, wind-powered electricity generation maintenance lifting platform is slowly sling, and hoists in process, and support roller 5 rolls on tower barrel, avoids wind-powered electricity generation maintenance other positions of lifting platform to touch tower cylinder.When wind-powered electricity generation maintenance lifting platform hangs while rising to tower cylinder top, winch braking, support roller hydraulic actuating cylinder 15 is slowly retracted, and clamp arm 13 and tower barrel are fitted, and clamping hydraulic cylinder 4 stretches out, and makes clamping mechanism be the state of holding tightly, holds tower cylinder tightly.Now, 9 actions of luffing hydraulic actuating cylinder, arm 17 starts to keep in repair hoisting operation.After maintenance activity, clamping hydraulic cylinder 4 is retracted, clamping mechanism is slowly opened, after mechanism to be clamped opens completely, support roller hydraulic actuating cylinder 15 stretches out, and support roller 5 is attached on tower barrel, winch starts, wind-powered electricity generation maintenance lifting platform slowly falls, until drop down onto ground, whole maintenance process is complete.
It is light that patent of the present invention has realized use structure, and easily the complex work of the minor crane tool of transportation maintenance large fan, has improved work efficiency, reduces blower fan maintenance cost.
