Problems solved by technology

[0004] However, in the actual use process, it was found that the support and fixation effect of the longitudinal support bar and the oblique support bar on the wind power blade mold frame itself is not ideal, and problems such as deformation and uneven deformation are prone to occur, which affects the production efficiency of the wind power blade mold
[0005] In the prior art, there are also auxiliary supporting and fixing tools used for the mold frame of wind power blades, but the supporting and fixing effect is not ideal

Abstract

The present invention provides a support frame for a wind power blade mold frame, comprising: a first support rod; a second support rod, the second support rod is perpendicular to the first support rod, and one end is fixedly connected to the first support rod; Three support rods, one end of the third support rod is fixedly connected to the first support rod, and the other end is fixedly connected to the second support rod; the fixed connection position of the third support rod on the second support rod conforms to the following relationship: S=n L , wherein, 3 / 5≤n≤7 / 10; S is the length of the connection between the third support rod and the second support rod from the first support rod; L is the length of the second support rod. The invention also provides a connection structure between the mold frame of the wind power blade and the supporting frame. The support frame for the mold frame of the wind power blade and the connection structure between the mold frame of the wind power blade and the support frame of the present invention can improve the fixing and supporting effect of the support frame on the mold frame of the wind power blade and improve the overall rigidity of the mold frame of the wind power blade.

Description

technical field [0001] The invention relates to the field of wind power blade molds, in particular to a support frame for a wind power blade mold frame and a connecting structure thereof. Background technique [0002] During the production cycle of the wind power blade mold, the mold is opened and laid flat for a long time, and the wind power blade mold frame is easily deformed due to the load of the blade and its own weight. [0003] In the prior art, those skilled in the art have provided longitudinal support rods and oblique support rods on the wind power blade mold frame to improve the rigidity of the wind power blade mold frame itself and reduce the occurrence of deformation. [0004] However, in the actual use process, it was found that the support and fixation effect of the longitudinal support bar and the oblique support bar on the wind power blade mold frame itself is not ideal, and problems such as deformation and uneven deformation are prone to occur, which affect...
