A kind of 8 points synchronous from lifting maintenance platform
Technical field
The present invention relates to a kind of fan repair technical field, particularly a kind of 8 points synchronous from lifting maintenance platform.
Background technology
The characteristics of in recent years wind power generation industry keeps fast development, wind-power electricity generation determines that wind power plant is in mostly
The more severe mountain area of meagrely-populated, environment, desert, seabeach, coastal waters near zone.
Wind-driven generator is the device for converting wind energy into electric energy, mainly by blade, generator, mechanical part and electrically
Part is constituted.Blade rotates under wind-force effect, drives generator operation in fan engine room to produce electric energy.
When part big in cabin occurs big failure, it is necessary to dismantle trouble unit, with crane by failure portion
Part is transported to ground;During installation, trouble unit is transported to into tower top with crane and is installed.At present, blower fan tower barrel is high
Degree just must can complete dismounting in maintenance typically between 60 to 80 meters with the assistance of goliath.And goliath
Transition transport it is relatively difficult, rent goliath itself expense it is also higher, cause traditional fan repair cost compared with
Height, it is less efficient.
Therefore, high-altitude maintenance cost how is reduced, improving maintenance efficiency becomes technical problem urgently to be resolved hurrily.
The content of the invention
For the problems referred to above, it is an object of the invention to provide synchronous from lifting maintenance platform, maintenance wind is reduced at a kind of 8 points
The cost and difficulty of machine, improves maintenance fan efficiency.
For achieving the above object, the present invention provide a kind of 8 points it is synchronous from lifting maintenance platforms, including base plate, motor,
The mechanisms such as decelerator, hoisting drum, directive wheel, hanger.The hoisting system that told motor, decelerator, hoisting drum are constituted is consolidated
It is scheduled on base plate;Directive wheel and hanger are separately fixed at the suitable position of base plate surrounding.
Drum mechanism built of the present invention is to be provided the synchronous interaction two-fold cylinder of power, each reel by same power source
Two parts are divided into again, per winds portions steel cable, realize four steel wire ropes of synchronous hoist.
Hoisting drum of the present invention, directive wheel, fixed pulley group, hanger are wound by the link of steel wire rope, define two
Individual suspension centre.Four groups of devices define altogether the suspension centre of eight synchronous ascendings.
The present invention can utilize fixed fixed pulley group on by climbing thing, realize when using from lifting, and can fully protect
The balance and stability of card platform.The maintenance to blower fan can be safely and effectively rapidly completed.Dismounting is also convenient for after use, it is convenient
Transition, it is adaptable to the maintenance of different blower fans.
The present invention can to hold device convenient fixed in tower by installing additional, installs that Lifting device is convenient to be risen to weight additional
Drop.

Fig. 2 is wire rope roll around schematic diagram.
Fig. 3 is the overall structure diagram of the present invention.
Wherein, 1- decelerators, 2- motor, 3- reels, 4- base plates, 5- directive wheels, 6- hangers, 7- fixed pulleys.
Specific embodiment
Carry out detailed exemplary and explanatory description to the present invention below in conjunction with the accompanying drawings.
As shown in figure 1, the figure shows one kind from jacking system, the system can be used in keep in repair blower fan when to tower top
Equipment is lifted and transported.
The shown hoisting mechanism from jacking system is made up of motor 2, decelerator 1, winding drum 3 and assisted delivery devices.
Each winding drum is divided into two parts, respectively two steel wire ropes of elevator
As shown in figure 1, four leading blocks 3 and four hangers 6 respectively constitute eight suspension centres, steel wire rope passes through respectively reel
3rd, directive wheel 5, assembly pulley 7, hanger 6 form one group of jack up unit.Four steel wire ropes define altogether eight Heave Heres, and eight are risen
Suspension centre synchronization lifting, realizes the balance of platform and stablizes.The canoe of steel wire rope is as shown in Fig. 2 shown fixed pulley group 7 is fixed
The appropriate position of the object sought connections with the platform, platform just can be smoothed out climbing and dismantling, safely and fast efficiently complete
Maintenance work.
As shown in figure 3, when the platform equipped with the hoisting system is keeped in repair to blower fan, the system of holding can be installed additional so as to handle
Blower fan is fixed in tower, and installing crane system additional can carry out the lifting to weight.
