Abstract
The utility model is a kind of wind-driven generator group wheel box high speed brake disc barring gear, comprise erection support and be fixed on the brake disc driven gear on draught fan impeller high speed brake disc outer surface, erection support is fixed on wind-driven generator group wheel box, erection support is equipped with drive motor and gear-box, the output shaft of gear-box is connected with the small gear engaged with brake disc driven gear.The utility model drive motor drives the brake disc driven gear on high speed brake disc to rotate, thus impeller rotates, and instead of heavy manual labor.Drive motor adopts variable-frequency motor, and the torque needed when can prevent impeller loads from changing changes.Use Self locking gears case to pin small gear, prevent the excessive gear-box that causes of the opposite force of impeller from reversing.
Description
Technical field
The utility model relates to a kind of wind-driven generator group wheel box high speed brake disc barring gear.
Background technique
Wind-power electricity generation is the important component part as China's energy resource structure, is the renewable energy sources having most in the recent period the prospect of large-scale developing and utilizing, and the wind power technology equipment of China has had significant progress in a period of time in the past.Because the common running environment of blower fan is relatively more severe, Wind turbines endures the erosion of thunder and lightning, dust storm, rainwater to the fullest extent, and some component are damaged and cannot avoid.Especially when the impeller of Wind turbines break down, blade be damaged time, blower fan cannot leave oar and run, but again whole vane rotary is keeped in repair to suitable position.A few individual is adopted to rotate high speed brake disc together under normal circumstances, the rotation of driven gear case and impeller.Such operating method inefficiency, labor intensity are large, have certain danger.And when having the direction of a wind and rotation inconsistent a little, impeller will bring very large resistance, cannot wheel rotor.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of structural safety, handling safety wind-driven generator group wheel box high speed brake disc barring gear easily.
Technical problem to be solved in the utility model is realized by following technological scheme, the utility model is a kind of wind-driven generator group wheel box high speed brake disc barring gear, be characterized in: comprise erection support and be fixed on the brake disc driven gear on draught fan impeller high speed brake disc outer surface, erection support is fixed on wind-driven generator group wheel box, erection support is equipped with drive motor and gear-box, the output shaft of gear-box is connected with the small gear engaged with brake disc driven gear.
Technical problem to be solved in the utility model can also be realized further by following technological scheme, and described wind-driven generator group wheel box high speed brake disc barring gear, is characterized in: described drive motor is variable-frequency motor.Variable-frequency motor adopts frequency conversion to export, and the torque needed when preventing impeller loads from changing changes.
Technical problem to be solved in the utility model can also be realized further by following technological scheme, described wind-driven generator group wheel box high speed brake disc barring gear, is characterized in: described brake disc driven gear is provided with two symmetrically arranged positioning holes and two symmetrically arranged fixing screw holes.
Technical problem to be solved in the utility model can also be realized further by following technological scheme, and described wind-driven generator group wheel box high speed brake disc barring gear, is characterized in: described gear-box is Self locking gears case.
When draught fan impeller needs jiggering, the braking clamp on draught fan impeller high speed brake disc is pulled down, by brake disc driven gear bolton on the outer surface of high speed brake disc.With the screw hole installing braking clamp, erection support is fixed on wind-driven generator group wheel box, then gear-box and drive motor is arranged on erection support.When needing jiggering, connect the power supply on drive motor, the pinion rotation on drive motor driven gear case and tooth case, tooth case small gear drives the brake disc driven gear on brake disc to rotate, and so just serves the effect of jiggering.
Compared with prior art, the utility model drive motor drives the brake disc driven gear on high speed brake disc to rotate, thus impeller rotates, and instead of heavy manual labor.Drive motor adopts variable-frequency motor, and the torque needed when can prevent impeller loads from changing changes.Use Self locking gears case to pin small gear, prevent the excessive gear-box that causes of the opposite force of impeller from reversing.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is mounting structure schematic diagram.
Fig. 3 is for using structural representation.
Embodiment
With reference to accompanying drawing 1, a kind of wind-driven generator group wheel box high speed brake disc barring gear, comprise the erection support 2 be fixed on wind-driven generator group wheel box and the brake disc driven gear 1 be fixed on draught fan impeller high speed brake disc 5 outer surface, erection support 2 is equipped with variable frequency drive motors 4 and Self locking gears case 3, the output shaft of Self locking gears case 3 is connected with the small gear engaged with brake disc driven gear 1.
Described brake disc driven gear 1 is all provided with four holes, wherein two are symmetrical arranged as positioning hole, and two other is symmetrical arranged as fixing screw hole.Use positioning hole and fixed bolt hole can ensure the small gear of gear-box 3 and the accuracy of mesh of brake disc driven gear 1.
During installation, use screw fastening on high speed brake disc 5 outer surface brake disc driven gear 1, utilize the original screw hole installing brake callipers to be fixed on wind-driven generator group wheel box 3 by jiggering erection support 2, then respectively gear-box 3 and drive motor 4 are fixed on erection support 2.The combination of drive motor 4 and gear-box 3 quite and speed reducer.
After barring gear installation, connect the power supply of drive motor 4, the pinion rotation on drive motor 4 driven gear case 3, small gear drives brake disc driven gear 1 to rotate, thus promotion wind-driven generator group wheel box 6 rotates.Then drive fan shaft system 7 to rotate, behind suitable position, disconnect the power supply of drive motor 4, so just serve the object rotating draught fan impeller.
