Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blades, and more specifically to a web turning mechanism. Background Art

[0002] As the capacity of wind turbine assembly continues to increase, the trend of large-scale wind turbine blades is becoming increasingly prominent. Currently, onshore blades have developed to the 100-meter level. The height of most old factories can no longer meet the production of 100-meter blades.

[0003] The web bonding requires a higher lifting height. When the workshop height does not meet the requirements for vertical placement of the web, the web needs to be laid flat first, and then placed vertically when it is lifted into the cavity at a sufficient height. Secondly, after the web is demoulded, the product needs to be placed vertically in the maintenance tooling. Both of the above steps require the web to be flipped from a flat position to a vertical position. At present, slings or fixed pulleys are commonly used for flipping, but both of the above methods have quality and safety risks. The flipping speed is uncontrollable, and the uneven density of the slings causes deformation of the web. The uncontrollable flipping speed will not only cause safety risks, but also the risk of product bumps or uneven force on the product. The above methods and the risks caused will restrict the current production of blades. A blade cavity web flipping tool similar to Patent No. CN202310532790.7 includes: two supports, the two supports are symmetrically arranged, and there is a gap in the middle; a number of flipping mechanisms, and a number of flipping mechanisms are arranged on the two supports. In between, several flipping mechanisms clamp different positions of the cavity web and flip them synchronously; the guiding mechanism, the guiding mechanisms are respectively arranged on two supports, and the guiding mechanisms include a folding state and an unfolding state. When the guiding mechanism is in the unfolding state, the lateral movement of the cavity web in or out of the several flipping mechanisms is guided, and when the guiding mechanism is in the folding state, the flipping of the cavity web is avoided; in this invention, several flipping mechanisms clamp different positions of the cavity web and then flip them synchronously to prevent the risk of twisting, cracking and deformation of the cavity web due to poor synchronization during the flipping process, and avoid the safety hazards existing in the process of manually assisted lifting and flipping; but the device is prone to safety problems caused by damage to the web caused by flipping and stalling of the web.

[0004] Therefore, there are shortcomings in the existing technical solutions, and it is impossible to avoid the safety problems caused by the web plate flipping damage and the web plate flipping stall caused by the web plate flipping at the current stage through the web plate flipping at a controllable speed. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the safety problems caused by the web plate flipping and the web plate flipping stall caused by the web plate flipping at a controllable speed in the prior art.

[0006] For this purpose, the adopted technical solution is that a web flipping mechanism of the present utility model includes a horizontal slide rail. A rack is fixed to the upper end of the horizontal slide rail. A slider is slidably arranged on the horizontal slide rail. A vertical connecting rod is fixed to the slider. Claw one and claw two for clamping the web are respectively arranged at both ends of the horizontal slide rail; A synchronous motor one and a synchronous motor two 4 for driving the web to flip are fixed to the vertical connecting rod.

[0007] Preferably, the synchronous motor one is fixed to the vertical connecting rod through a motor base, and the driving gear of the synchronous motor one meshes with the rack.

[0008] Preferably, the synchronous motor two is fixed to the upper end of the vertical connecting rod through a motor base. The synchronous motor two drives a wire rope tightening roller to rotate. A wire rope is wound around the wire rope tightening roller, and the other end of the wire rope is fixed to a wire rope connection seat.

[0009] Preferably, the wire rope connection seat is fixed to one end of the horizontal slide rail.

[0010] Preferably, double rollers are rotatably arranged in the slider, and the double rollers are in sliding contact with the horizontal slide rail.

[0011] Preferably, a claw lock one for clamping the web is connected to claw one through a threaded fit.

[0012] Preferably, a plurality of slots for side clamping are uniformly arranged at the side end of claw one.

[0013] Preferably, an adjustment chute is penetrated through the horizontal slide rail. A claw center rod is fixed in claw two, and claw two slides in the adjustment chute through the claw center rod.

[0014] Preferably, a distance adjustment screw rod is rotatably arranged in the horizontal slide rail and the adjustment chute. The distance adjustment screw rod is connected to the center of the claw center rod through a threaded fit.

[0015] Preferably, a claw lock two for adjusting the clamping is connected to claw two through a threaded fit.

The synchronous motor one 2 is used to control the rotation of the gear and the roller to drive the flipping. The ±90° rotation is realized through the connection of the vertical connecting rod 3 with the connecting rod mechanism. At the same time, by installing a fixed pulley, a safety steel wire rope is used to connect the synchronous motor two 4 to realize the flipping assistance and safety protection functions. The length of the connecting rod mechanism is determined according to the width of the corresponding position of the web. Different clamping devices are installed on both sides of the connecting rod. At the same time, the connecting rod mechanism can rotate 180°, and the web can be rotated and clamped according to the vertical placement posture of the web and be vertically placed.

[0033] It is mainly applied to the vertical placement of the demolded web and the situation where the workshop height is insufficient.
