Description
Technical field
The utility model belongs to technical field of wind power generation, particularly relates to a kind of wind-driven generator group wind-wheel shaft turning gear.
Background technique
Often need to rotate Transmitted chains at wind power generating set locking wind wheel and the operation of coupling centering, along with developing rapidly of wind-powered electricity generation industry, single unit capacity does larger and larger, unit main parts size blade, wheel hub, main shaft, tooth case equal-volume increases, and weight increases, Transmitted chains rotary inertia also increases thereupon, the dynamic wind wheel operation of dish becomes more and more difficult, and on-the-spot wind regime is complicated and changeable in addition, and Transmitted chains rotates suddenly and easily brings high risks to operator.
Current dish moves wind wheel and mainly contains two kinds of modes: a kind of mode directly uses spanner rotating joint thus drives Transmitted chains to rotate, and this mode is required great effort and be there is great potential safety hazard very much; Another kind of mode is that brake disc outer rim is processed into profile of tooth, and on tooth case, drive unit is installed, drive unit small gear and the engagement of brake disc gearwheel, the object of the dynamic wind wheel of dish is reached by rotating brake disc, the shortcoming of this mode is that machining accuracy is high, unit cost is high, and versatility is bad, and cannot use during unit power-off.
Summary of the invention
Moving that wind wheel mode is required great effort, cost is high to overcome existing dish, having potential safety hazard, deficiency that versatility is bad, the utility model provide a kind of operate light, reduce costs, eliminate safe hidden trouble, the wind-driven generator group wind-wheel shaft turning gear of highly versatile.
The utility model solves the technological scheme that its technical problem adopts:
A kind of wind-driven generator group wind-wheel shaft turning gear, the main shaft of described wind-driven generator is connected with coupling, described wind wheel shaft turning gear comprises hinge wheel, minor sprocket and worm speed reducer, described hinge wheel is fixed on described coupling, ring chain is sleeved on hinge wheel and minor sprocket, described minor sprocket is positioned at the below of hinge wheel, described minor sprocket is arranged on the output shaft of worm speed reducer, the input shaft of described worm speed reducer is provided with power intake, described worm speed reducer is arranged on mounting bracket, and described mounting bracket is positioned in cabin seat.
Further, described hinge wheel comprises left half wheel and right half wheel, and the described right side half wheel is enclosed within the connection expansion set of main shaft, and a described left side half wheel is enclosed within the connection expansion set of coupling, and a described left side half wheel is fixedly connected with right half wheel.
Further again, described power intake is electric wrench input end.
Or: described power intake installs swinging handle.
Further, described mounting bracket is provided with the elongated slot regulating centre of sprocket distance.
Main beneficial effect of the present utility model shows: 1, equipment volume is little, lightweight, low cost of manufacture; 2, package unit is installed by tapped hole existing on expansion set, and do not need to change existing coupler structure, versatility is good; 3, worm speed reducer comprises worm drive, can realize the little moment of torsion of input one and export a very large moment of torsion by selecting a large velocity ratio; 5, because worm drive has good self-locking property, during operation, effectively can prevent the rotation of wind wheel under wind carries effect, avoid producing serious accident; 6, crank handle is provided with electric wrench joint, connects electric wrench during energising, flexible operation, laborsaving, convenient.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to Fig. 1 ~ Fig. 4, a kind of wind-driven generator group wind-wheel shaft turning gear, the main shaft 4 of described wind-driven generator is connected with coupling 3, described wind wheel shaft turning gear comprises hinge wheel 1, minor sprocket 8 and worm speed reducer 6, described hinge wheel 1 is fixed on described coupling 3, ring chain 5 is sleeved on hinge wheel 1 and minor sprocket 8, described minor sprocket 8 is positioned at the below of hinge wheel 1, described minor sprocket 8 is arranged on the output shaft of worm speed reducer 6, the input shaft of described worm speed reducer 6 is provided with power intake 7, described worm speed reducer 6 is arranged on mounting bracket, described mounting bracket is positioned in cabin seat 10.
Further, described hinge wheel 1 comprises left half wheel 11 and right half wheel 13, and the described right side half wheel 13 is enclosed within the connection expansion set of main shaft 4, and described left half wheel case 11 is on the connection expansion set of coupling 3, and a described left side half wheel 11 is fixedly connected with right half wheel 13, is fixed by bolt 12.
Further again, described power intake 7 is electric wrench input end.
Or: described power intake 7 installs swinging handle.
Further, described mounting bracket 9 is provided with the elongated slot regulating centre of sprocket distance.
In the present embodiment, the tensioning degree of elongated slot adjusting chain bottom mounting bracket is first utilized during use, then by shake crank handle or the joint 71 connecting electric wrench input torque at electric wrench input end, through worm speed reducer worm drive and between hinge wheel and minor sprocket Chain conveyer drive coupling to rotate, most final quotation moves whole wind wheel.
