Abstract
The invention discloses an eight-point automatic lifting maintenance platform. The ultrahigh maintenance platform can particularly lift an extra heavy object and can be balanced under the background conditions of high fan maintenance cost and difficulty. The eight-point synchronous automatic lifting maintenance platform comprises a bottom plate, a motor, a speed reducer, lifting drums, guide wheels, lifting lugs and the like. The eight-point synchronous automatic lifting maintenance platform has the advantages that a lifting system is connected with the drums, the guide wheels, fixed pulleys and the bottom plate by four groups of steel wire ropes, so that eight points of the object can be synchronously lifted, and the lifting platform with multiple lifting points can be balanced; the platform can reach a preset position or altitude on the basis of the positions of the four fixed pulleys; the eight-point synchronous automatic lifting maintenance platform is free of constraints of maximum lifting height and places, can be applied to maintaining various facilities and brings convenience for transition and transportation; particularly, workers can conveniently and quickly climb to positions near a cabin when fans are maintained, so that the maintenance cost can be reduced, and the operation efficiency can be improved.
Description
Technical field
The present invention relates to a kind of blower fan maintenance technique field, particularly a kind of 8 synchronously from lifting maintenance platform.
Background technology
Wind-power electricity generation industry keeps fast-developing in recent years, and the feature of wind-power electricity generation has determined that wind power plant is in the mountain area meagrely-populated, environment is more severe, desert, seabeach, coastal waters near zone mostly.
The device that aerogenerator is is electric energy by wind energy transformation, is mainly comprised of blade, electrical generator, mechanical part and electric component.Blade rotates under wind-force effect, drives generator operation in fan engine room to produce electric energy.
When large fault occurs large parts in cabin, just trouble unit need to be dismantled, with hoisting crane, trouble unit is transported to ground; During installation, with hoisting crane, trouble unit is transported to tower cylinder top and installs.At present, blower fan tower barrel height generally, between 60 to 80 meters, must just can complete dismounting with the assistance of goliath when maintenance.And the transition of goliath transportation is more difficult, the expense of renting goliath itself is also higher, causes traditional blower fan maintenance cost higher, and efficiency is lower.
Therefore, how to reduce high-altitude maintenance cost, improve maintenance efficiency and become technical matters urgently to be resolved hurrily.
Summary of the invention
For the problems referred to above, the object of this invention is to provide at a kind of 8 and reduce cost and the difficulty of maintenance blower fan synchronously from lifting maintenance platform, improve maintenance fan efficiency.
For achieving the above object, the invention provides a kind of 8 synchronously from lifting maintenance platform, comprise the mechanisms such as base plate, electrical motor, retarder, hoisting drum, track adjusting wheel, hanger.The hoisting system that the electrical motor of telling, retarder, hoisting drum form is fixed on base plate; Track adjusting wheel and hanger are separately fixed at the position that base plate surrounding is suitable.
Drum mechanism built of the present invention is for being provided the two reels of synchronous interaction of power by same propulsion source, each reel is divided into again two parts, and every part coiling steel cable is realized four steel ropes of synchronous hoist.
Hoisting drum of the present invention, track adjusting wheel, fixed pulley group, hanger are reeled by the link of steel rope, have formed two some suspension centres.Four groups of these devices have formed the suspension centre of eight synchronous ascendings altogether.
The present invention can utilize being climbed fixing fixed pulley group on thing, realizes from lifting, and can fully guarantee balance and the stability of platform during use.Can the safe and effective maintenance completing fast blower fan.Also for convenience detach after use, facilitate transition, be applicable to the maintenance of different blower fans.
The present invention can be convenient fixing on tower cylinder by adding clamping embracing unit, installs the convenient landing to weight of Lifting device additional.
Accompanying drawing explanation
Fig. 1 is hoisting system schematic diagram.
Fig. 2 is that wire rope roll is around schematic diagram.
Fig. 3 is integral structure schematic diagram of the present invention.
Wherein, 1-retarder, 2-electrical motor, 3-reel, 4-base plate, 5-track adjusting wheel, 6-hanger, 7-fixed pulley.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is carried out to exemplary and explanatory description in detail.
As shown in Figure 1, this figure has shown a kind of from jacking system, and this system lifts and transports tower cylinder top equipment while can be used in maintenance blower fan.
Shown in from the hoisting mechanism of jacking system by electrical motor 2, retarder 1, winding drum 3 and auxiliary transmission installation composition.Each winding drum is divided into two parts, respectively two steel ropes of elevator
As shown in Figure 1, four leading sheaves 3 and four hangers 6 form respectively eight suspension centres, and steel rope forms one group of jack up unit by reel 3, track adjusting wheel 5, assembly pulley 7, hanger 6 respectively.Four steel ropes have formed altogether eight Heave Heres, eight Heave Here synchronization liftings, the balance of implementation platform and stable.The canoe of steel rope as shown in Figure 2, shown in fixed pulley group 7 be fixed on the suitable position of object that this platform is sought connections with, platform just can climb smoothly and dismantle, and efficiently completes safely and fast maintenance work.
As shown in Figure 3, when the platform that this hoisting system is housed keeps in repair blower fan, can add that clamping is embraced system to blower fan is fixed on tower cylinder, install crane system additional and can carry out the lifting to weight.
