Clamping device for lifting assembled shear web plates in wind turbine blade

Abstract

The invention discloses a clamping device for lifting assembled shear web plates in a wind turbine blade, which belongs to the technical field of lifting clamps for megawatt wind turbine blades. A left clamp (2) and a right clamp (3), which have the same structures, are connected with each other through a center shaft (10) to form an X-shaped structure; a vertical beam (1) and a cross beam (4) form a middle balance supporting arm with a T-shaped structure; a left supporting rod (5) and a right supporting rod (5) are arranged at two ends of the cross beam (4) and are connected with the cross beam (4) to form a rotating supporting structure through shafts (6); the shear web plate clamping device is kept under a static structure posture by a spring (7). The inner assembled shear web plate clamping device provided by the invention can lift and mount the assembled shear web plates in a balanced manner and guarantees the assembling technical sizes of the shear web plates; the deformation of the web plates is alleviated to the maximum extent; the production efficiency is improved; the quality of the blade is guaranteed; the clamping device is simple in structure and convenient to use and can be quickly mounted and dismounted in a low position.

Description

technical field [0001] The invention belongs to the technical field of hoisting fixtures for megawatt wind power generation blades, and mainly relates to a clamping device for hoisting and transporting the assembled shear web inside the wind power generation blades. Background technique [0002] The shear web is an internal structure to improve the shear strength of the wind power blade. Generally, two shear webs are preformed and then installed and fixed inside the wind power blade according to specific design requirements. [0003] In the prior art, there are several methods for hoisting and installing the shear webs inside the blades of wind power generation: 1. Lift and install the shear webs one by one by using the lifting fixture; 2. Use the lifting fixture to lift the two shear webs Simultaneous lifting and installation; 3. After simple assembly of the two shear webs in advance, use lifting fixtures for lifting and installation. Comparing the above three lifting ...

Problems solved by technology

Patent No. 201020542936.4 "Megawatt Wind Turbine Shear Web Lifting Fixture Device" discloses a shear web lifting fixture device. From its technical scheme, although it solves the problem of lifting two shear webs at the same time, it also simplifies the shear web. The problem of hoisting and installation after pre-assembly, but for two shear webs that are not pre-assembled, it cannot meet the accuracy of the distance between the shear webs in the length direction, especially for the root tip of the shear web Position, from the content of the disclosed technical proposal, if you want to improve the accuracy of the distance between positions in the length direction, you need to increase the number of tooling, the number of cranes, or use auxiliary equipment such as hanging beams, and the height of the shear web length direction varies greatly , using tooling positioning installation, the bonding and pressing down after installation and the removal of tooling are more cumbersome, resulting in a longer stagnation time in the subsequent process, even if the shear web is simply assembled in advance to avoid deformation in the length direction and accurate spacing of each position performance, but the installation and disassembly of this clamp device is also relatively cumbersome, especially for shear webs with high roots
