Abstract
The utility model discloses a maintenance crane for a large-sized wind generating set, which comprises a control device, an overhead traveling crane which is arranged inside a machine cabin, a speeduppulley block, a hanger which is used for joining and fixing a maintained part and a windlass which is arranged on a basic platform of the wind generating set and is controlled by the control device,the speedup pulley block is connected with the windlass through a wire cable which rounds a guide pulley which is arranged inside the machine cabin, and the speedup pulley block is installed on the overhead traveling crane and is connected with the hanger. The crane can hoist large-sized components (such as blade, speed increaser, power generator and the like) inside the machine cabin to the basicplatform or from the basic platform into the machine cabin; and by changing the multiplying power of the pulley block and the winding way of the wire cable and arranging an appropriate hanger, the hoisting of all components inside the machine cabinet of the large-sized power generating set can be satisfied. The crane has the advantages of convenience, high efficiency and low cost.
Description
Technical field
The utility model relates to a kind of crane, more particularly, relates to a kind of maintenance crane that is used for Large-scale Wind Turbines.
Background technology
There are three problems in the maintenance of main parts size with replacing in the Large-scale Wind Turbines at present:
1, engine room inside narrow space, maintenance is difficult in engine room inside and finishes.
2, the weight of main parts size is heavier, and for Generator Set, the weight of its electrical generator, booster engine generally all more than ten tons, need have the equipment of enough lifting abilities.
3, the setting height(from bottom) in cabin is unfavorable for maintenance and lifting generally more than 70 meters.
For this reason, the method that adopts at present generally has three kinds:
First kind is to use the large-tonnage crawler crane, and whole cabin or gear case are hung on the ground, then gear case is keeped in repair.This mode is not only not convenient, and costly.
Second kind is that elevator is arranged in the cabin, hang on the basic platform from the cabin damaging the part that needs to change, need in the cabin, arrange the winch that liter weight is big like this, because the weight of winch self is just very big, therefore the unit design of aerogenerator and the layout of each parts are produced certain influence, and because the control housing of winch that the space is limit and operator's station are arranged and operation inconvenience very difficult.
The third be in the cabin, arrange a hoisting capacity at one ton with interior hoist ceiling crane.This can only lift by crane part, and can not the bigger parts of integral hoisting weight, if the bigger damage parts of weight must be hung whole cabin on the ground with the large-tonnage crawler crane and be keeped in repair.
The utility model content
The purpose of this utility model is to provide a kind of maintenance crane that is used for Large-scale Wind Turbines, utilizes this maintenance crane can convenient and efficient, expense is cheap relatively mode to finish the lifting problem of high-altitude, heavy parts.
The maintenance crane that is used for Large-scale Wind Turbines in the utility model, include control setup, be located at engine room inside driving, speedup assembly pulley, be used to be connected and fixed the suspender of Awaiting Parts and be located on the wind power generating set basic platform winch by described control setup control, be connected by the steel rope of walking around the guide pulley that is located at described engine room inside between described speedup assembly pulley and the described winch, described speedup assembly pulley is installed in the described driving, is connected with described suspender simultaneously.
Described speedup assembly pulley is 8 times of fast speedup assembly pulleys.
Described winch is connected with the motor of being controlled by described control setup.
Described speedup assembly pulley includes running block and fixed pulley group.
The maintenance crane that is used for Large-scale Wind Turbines in the utility model can winch to the large component of engine room inside on the basic platform or from basic platform and hang in engine room inside, has the cheap relatively advantage of convenient and efficient, expense.
Description of drawings
Fig. 1 is the structural representation of maintenance crane in the utility model;
Fig. 2 among Fig. 1 along the enlarged diagram of analysing and observe of A-A line.
The specific embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the maintenance crane that is used for Large-scale Wind Turbines in the utility model includes winch 2, steel rope 3, guide pulley 4, speedup assembly pulley 5, suspender 6 and control setup 8 and drives a vehicle 9.Wherein:
Speedup assembly pulley 5 is made up of fixed pulley group and running block, and winch 2 is installed on the basic platform 1 by motor-driven, and motor is controlled by control setup 8, thereby further controls winch 2.Winch 2 is connected with an end of steel rope 3, the other end of steel rope 3 extends into engine room inside, walking around guide pulley 4 is connected with fixed pulley group in the speedup assembly pulley 5, fixed pulley group in the speedup assembly pulley 5 is installed in the driving 9 of engine room inside, be connected with suspender 6 by running block in the speedup assembly pulley 5 and steel rope, speedup assembly pulley 5 can adopt 8 multiplication ski-running wheels mechanisms, and suspender 6 is used for fixing the suspension centre of connection gear case 7.When starting winch 2, gear case 7 can be sling, withdraw from the cabin, drop on the ground-surface basic platform 1, after reparation, can deliver in the cabin again.
The advantage that is used for the maintenance crane of Large-scale Wind Turbines in the utility model is:
1, control device 8 is installed on the basic platform 1 with hoist engine 2, and hoist engine 2 is by frequency control Can reach the desirable speed of service, simultaneously disposed counter at hoist engine 2, can know weight Instant height.
2, owing to adopt zoom rate assembly pulley, can satisfy all zero ones of Large-scale Wind Turbines engine room inside The lifting of part.
3, because hoist engine is arranged on the basic platform, a cover maintenance crane can satisfy many typhoons power generator The lifting of gear-box is used.
4, easy to operate, owing to hoist engine, control device are arranged on the basic platform on ground, the space is well-to-do, Be convenient to assembling personnel's operation.
5, no longer need the large-tonnage crawler crane, thereby can save the expense of lease or transportation, except low-cost.
