Detailed description of the invention
Hereinafter, with reference to the accompanying drawings to describe embodiments of the invention in detail.
Embodiment one
The present embodiment is the embodiment of the part replacement device of wind-driven generator, below by the part replacement device of the wind-driven generator that makes introductions all round from the following aspects.
(1) overall structure
Overall structure below in conjunction with the part replacement device of Fig. 2 to 4 illustratively the present embodiment, as shown in Figures 2 and 3, the part replacement device of the wind-driven generator of the present embodiment includes base 1 and arranges hoisting mechanism 2 on the base, described base is provided with traction enhancement portion 11, this traction enhancement portion 11 is connected by drawing connector 5 with the first traction connecting portion 4 being arranged on precalculated position in described tower 3, drives described part replacement device to move up along described tower 3 in the way of traction.
Fig. 3 it illustrates part replacement device state in traction uphill process, and Fig. 4 then illustrates that part replacement device arrives precalculated position, and fixing after state.
By Fig. 2 to Fig. 4 it can be seen that compared with the hydraulic pressure climbing mechanism of prior art, the hoisting mechanism of the part replacement device of the present embodiment is more simple, manufacturing cost is relatively low, and in the process of lifting piece more changing device, it is not necessary to large lifting equipment, installation cost is relatively low.
(2) traction enhancement portion
Referring to Fig. 2 to Fig. 5, wherein, Fig. 5 is the overall structure schematic diagram of the base of the part replacement device of the wind-driven generator of the embodiment of the present invention one, and it illustrates the structure in the traction enhancement portion being arranged on base from depression angle. Traction enhancement portion 11 and the critical piece that traction connector 5 is lifting piece more changing device, traction enhancement portion 11 can include hoist engine 111 and the second traction connecting portion 112 (as shown in Figure 5), traction connector 5 can be draught line 5, more specifically, draught line 5 can adopt steel wire traction line, as shown in Figure 3, first traction connecting portion 4 can be specially the first pulley mechanism 41, draught line 5 is drawn from hoist engine 111, through the first pulley mechanism 41, it is fixed on the second traction connecting portion 112.
By adopting the combination of pulley mechanism, hoist engine and steel wire traction line, it is simple to promote whole part replacement device.
Further, the structure gone out as shown in Figure 3 can be adopted, first pulley mechanism 41 includes multiple first pulley 411 (such as, Fig. 3 illustrates 2 pulleys), second traction connecting portion 112 includes at least one second pulley 1121 and draught line fixing point 1122, and (this draught line fixing point can also be pulley, simply it is as the fixing point of draught line one end), draught line 5 is drawn from described hoist engine 111, alternately across the first pulley 411 and the second pulley 1121, it is fixed on draught line fixing point 1122. As it is shown on figure 3, draught line 5 is after hoist engine 111 extraction, alternately pass through three pulleys, an i.e. pulley 1121 on two pulleys 411 on tower top and base, it is finally fixed on the pulley as draught line fixing point 1122, it can be seen that define 4 draught lines side by side.
Combination by multiple pulleys so that draught line can interlock between the pulley of base and the pulley of tower, and then makes in the process of the lifting of part replacement device, and pull strength can balancedly act on base.
Additionally, described traction enhancement portion 11 can be multiple, be symmetricly set on described base, with multiple described first traction connecting portions 4 corresponding connection.As shown in Figures 2 and 3, traction enhancement portion 11 is arranged on the symmetrical position of base, shown in figure, is provided with two traction enhancement portions 11 altogether, so in the process promoted, it is possible to make whole base steadily increase.
(3) base
As shown in Figures 2 and 3 the base of the present embodiment could be formed with the opening around tower, in the process that more changing device rises along tower, between inwall and the tower of opening, leave gap.
Owing to leaving gap between inwall and the tower of opening, changing in the process that mechanism rises whole, the inwall of opening will not come in contact with the surface of tower, it is possible to avoids damage to the face coat of tower. On the contrary, the climbing mechanism of prior art, in its process climbed, constantly to there is contacting of big frictional force with the inwall of tower, the face coat of meeting major injury tower, and this defect, be non-existent in the present embodiment.
