Description
Technical Field
The utility model relates to a wind-powered electricity generation blade field of making specifically is a rotatory lifting device for wind-powered electricity generation blade.
Background
The development of wind power generation depends on producing and manufacturing a large number of wind power generators, the wind power generators cannot leave blades, the wind power generator blades are of a thin shell structure made of composite materials and generally consist of a root part, a shell and reinforcing ribs or beams, in order to meet market demands, the blades are manufactured increasingly, the manufacturing process is complex, and the weight of the blades is large due to materials. At present, in the production process of blades, wind power blades are generally required to be continuously changed in storage postures (the blades are horizontally placed or stored at 90 degrees), so that equipment is required to realize the rotation of the blades; however, there are two kinds of rotating blade solutions in the prior art: firstly, the blade rotation is realized through a blade root circle vehicle and a blade tip circle vehicle, and the scheme has the defects that the structure of the hanging point position of the tip part of the blade is weak, and the blade tip circle vehicle is in hard contact with the blade, so that the blade is easily damaged by the circle vehicle in the rotation process; the second is that the blade tip circle car is replaced to an unpowered rotatory hoist and blade root circle car cooperation is used, and the shortcoming of this scheme is, and the rotatory in-process of blade relies on the drive of blade root circle car completely, can lead to the rotatory in-process of blade to cause the torsion damage because of the atress is uneven, consequently needs to develop an equipment cooperation blade root circle car, realizes blade root apex synchronous revolution, and rotatory process atress is even, reduces the impaired risk of blade.
SUMMERY OF THE UTILITY MODEL
To above technical problem, the utility model aims to reach the technical effect that a can cooperate blade root circle car is provided, realizes blade root apex synchronous revolution, and rotatory process atress is even, reduces the rotatory lifting device of wind-powered electricity generation blade of the impaired risk of blade.
For solving the technical problem, a rotatory lifting device for wind-powered electricity generation blade, including speed reducer, motor, rubber coating suspender, the motor connect in speed reducer one side, this speed reducer output is connected with the action wheel, speed reducer top fixedly connected with lug, lower extreme fixedly connected with frame, rotate in the frame and be connected with the driven shaft, this driven shaft one end fixedly connected with from the driving wheel, the action wheel pass through the belt with connect from the driving wheel, the cover is equipped with the rubber coating suspender on the driven shaft.
Further, the speed reducer is connected with the output end of the motor through a spring coupling.
Compared with the prior art, the utility model has the following advantage:
1. the utility model discloses a set up the rotatory wind-powered electricity generation blade apex position of rubber coating suspender hoist and mount for realize the soft contact between wind-powered electricity generation blade apex and the suspender, effectively avoided the blade to be hindered by the card.
2. The utility model discloses a motor drive rubber coating suspender makes apex and synchronous rotation of blade root, rotates in-process blade atress even, and the centre can not produce torsion and damage the blade.
3. The utility model discloses set up the spring coupling between motor and speed reducer, can effectively reduce the vibration sense that the motor operation produced, and then promoted the stability of blade at the rotatory in-process of hoist and mount.

In the figure: 1. the rubber-coated lifting belt comprises a motor, 2, a speed reducer, 3, a rack, 4, a spring coupling, 5, lifting lugs, 6, a driving wheel, 7, a belt, 8, a driven wheel, 9, a driven shaft, 10 and a rubber-coated lifting belt.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the rotary hoisting equipment for wind power blades comprises a speed reducer 2, a motor 1 and a rubber-coated hanging strip 10, wherein in order to provide rotary power, the motor 1 is connected to one side of the speed reducer 2, the output end of the speed reducer 2 is connected with a driving wheel 6, in order to hoist the rotary hoisting equipment, the top end of the speed reducer 2 is fixedly connected with a lifting lug 5, the lower end of the speed reducer 2 is fixedly connected with a rack 3, in order to drive the rubber-coated hanging strip 10 to rotate, the rack 3 is rotatably connected with a driven shaft 9, one end of the driven shaft 9 is fixedly connected with a driven wheel 8, the driving wheel 6 is connected with the driven wheel 8 through a belt; in order to realize synchronous rotation of the blade root and the blade tip in the rotation process of the blade, the diameters of the driving wheel and the driven wheel and the speed reducer speed ratio are obtained through calculation, the calculation process is that marking points are respectively made on the rotation position of the blade root and the hanging strip, the displacement relation between the marking points of the rotation position of the blade root and the marking points on the hanging strip is calculated through one rotation of the blade, the calculation relation between the output power of the blade root loop vehicle and the output power of the equipment is obtained, and the diameters of the driving wheel and the driven wheel, the speed reducer speed ratio and the like are determined according; the synchronous start and stop of the leaf root ring vehicle and the motor 1 of the optional hoisting equipment are controlled through electrical linkage.
In order to reduce the vibration sense brought by the motor 1 during the operation of the equipment and ensure the stability of the blades during the rotating and hoisting, the speed reducer 2 is connected with the output end of the motor 1 through the spring coupling 4.
The working process of the utility model is as follows:
before the wind power blade is rotationally hoisted, a lifting lug 5 on the equipment is hung on a travelling crane, then a rubber-coated hanging strip 10 is sleeved on the blade tip of the wind power blade, the blade root is clamped on a blade root ring vehicle, the blade root ring vehicle and a motor 1 are synchronously started through linkage control, the motor 1 drives a driving wheel 6 to rotate through a speed reducer 2, the driving wheel 6 drives a belt 7 to drive a driven wheel 8 to rotate, the driven wheel 8 drives a driven shaft 9 to rotate, the driven shaft 9 rotates and simultaneously enables the rubber-coated hanging strip 10 sleeved on the driven shaft 9 to rotate, the rubber-coated hanging strip 10 drives the blade tip to rotate through friction force, the rubber-coated hanging strip 10 is in soft contact with the blade tip in the rotating process, the path change of the blade when the blade tip rotates can be met, the blade.
