Abstract
The utility model discloses a mobile type turning device of a wind generating set, relates to wind generating sets, and solves the technical problem that the turning of a large wind generating set can not be realized manually. The mobile type turning device consists of a bracket with a sliding groove, a locking pin, a pushing rod mechanism, a positioning stopper, a driving device, a driving support and a connecting bolt, wherein the driving device is fixed on the driving support by the connecting bolt; the driving support is arranged in the bracket with the sliding groove and is connected with a pushing rod of the pushing rod mechanism; the pushing rod is matched with a nut arranged on the bracket; the upper end of the pushing rod is connected with a hand wheel; the bracket is provided with the positioning stopper of the turning position; the driving support is provided with a positioning hole which corresponds to the turning position and is used for placing the locking pin. The mobile type turning device disclosed by the utility model is used for maintenance of the wind generating set and has the advantages of being simple in turning operation, safe and reliable.
Description
Technical field
The utility model relates to the barring gear of wind power generating set, particularly the portable barring gear of a kind of wind power generating set.
Background technique
After wind power generating set must rotate to wind wheel locked position (usually pan of a steelyard car) locking, maintenance in the wheel hub of being allowed for access.At present, mostly adopt manpower manual jiggering (as shown in Figure 1).Along with wind power generating set maximizes, rotor diameter continues to increase, and hand turning is also more and more difficult, even can't realize.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of wind power generating set portable barring gear, solves the technical problem that the Large-scale Wind Turbines manpower can't be realized jiggering.
The utility model is achieved through the following technical solutions:
The portable barring gear of a kind of wind power generating set, it is characterized in that: described portable barring gear is by the support with chute, stop pin, transfer bar mechanism, position block, drive unit (motor reducer small gear three-in-one structure), driving bearing and connecting bolt forms, described drive unit is fixed on by connecting bolt and drives on the bearing, driving bearing is installed in the support with chute, and be connected with the push rod of transfer bar mechanism, push rod cooperates with nut on being installed in described support, the push rod upper end is connected with handwheel, be provided with the position block of jiggering position on the described support, be provided with corresponding with the jiggering position at the driving bearing, place the positioning hole of stop pin.
The utility model compared with prior art utilizes the feed screw nut principle, and will rotatablely move to be converted into moves forward and backward, the handwheel of rotating push rod mechanism, thus realize that drive unit moves to the jiggering position along the chute of support, insert in the positioning hole stop pin fixing.By the gearwheel on the drive unit driving main drive chain of wind generating set, finish the rotation to wind wheel again.
The utility model is used for the wind power generating set maintenance, has jiggering advantage simple to operate, safe and reliable.
Description of drawings
Fig. 1 is the schematic representation of prior art hand turning;
Fig. 2 is the structural representation (plan view) of the portable barring gear of a kind of wind power generating set;
Fig. 3 is the plan view of Fig. 2.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
Embodiment
Such as Fig. 2, shown in 3, the portable barring gear of a kind of wind power generating set, by the support 1 with chute, stop pin 2, transfer bar mechanism 3, position block 4, drive unit (motor reducer small gear three-in-one structure) 5, drive bearing 6 and connecting bolt 7 compositions, described drive unit 5 is fixed on by connecting bolt 7 and drives on the bearing 6, driving bearing 6 is installed in the support 1 with chute, and be connected with the push rod 3-1 of transfer bar mechanism 3, push rod 3-1 cooperates with nut 3-2 on being installed in described support 1, push rod 3-1 upper end is connected with handwheel 3-3, be provided with the position block 4 of jiggering position on the described support 1, be provided with corresponding with the jiggering position at driving bearing 6, place the positioning hole of stop pin 2.
The utility model utilizes the feed screw nut principle, the handwheel 3-3 of rotating push rod mechanism 3, thereby realize to drive bearing 6 and drive unit 5 thereof and move to position block (jiggering position) 4 places along the chute with the support 1 of chute, insert in the positioning hole stop pin 2 fixing, the gearwheel 8 that drives on the main drive chain of wind generating set by drive unit 5 is again finished the rotation to wind wheel.When the maintenance wind wheel, simple to operate, safe and reliable.
