Abstract
Description
Technical Field
[0001] This utility model relates to the field of decommissioned wind turbine blade clamping technology, specifically an adjustable clamping device for decommissioned wind turbine blades. Background Technology
[0002] Wind turbine blades are mainly composed of materials such as glass fiber, carbon fiber, epoxy resin, and balsa wood, among which glass fiber has excellent mechanical properties. For retired wind turbine blades, existing processing methods include cutting, trimming, and drilling to ensure their physical properties.
[0003] Currently, most clamping or pressing devices for retired wind turbine blades use curved plates with the same shape as the blades on both sides for clamping or pressing. However, different blade sizes have different shapes and sizes, so if the blades need to be replaced, the curved plates need to be replaced, increasing manufacturing costs. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable clamping device for retired wind turbine blades to solve the problems existing in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable clamping device for retired wind turbine blades, comprising a base 1, characterized in that: the base 1 is welded and fixed to the upper support plate 6 via a support frame 3, and two movable plates 2 that can slide separately are provided between the base 1 and the upper support plate 6, and the movable plates 2 are provided with more than 4 adjustable rods 10 that can be adjusted in height separately.
[0006] Furthermore, the movable plate 2 is provided with an equal number of adjusting seats 8 as the adjusting rod 10. The adjusting seats 8 are coaxial with the adjusting rod 10 and are connected by threads, and are fixed with locking nuts 9.
[0007] Furthermore, the inner side of the support frame 3 is provided with a linear rail 4, and the linear rail 4 is provided with a lower slider 2 and an upper slider 5 respectively. The two movable plates 2 are fixedly connected to the lower slider 2 and the upper slider 5 respectively.
[0008] Furthermore, a lower hydraulic cylinder 13 is provided below the base 1, and the front end of the lower hydraulic cylinder 13 is fixedly connected to the lower movable plate 2; an upper hydraulic cylinder 7 is provided above the upper support plate 6, and the front end of the upper hydraulic cylinder 7 is fixedly connected to the upper movable plate 2.
[0009] Furthermore, each of the adjusting rods 10 is provided with a spherical pressing block 11 below it.
[0010] Furthermore, the outer ring of the clamping block 11 is covered with a 5-10mm rubber layer.
[0011] This utility model has the following advantages: First, the position of the clamping block can be freely adjusted according to the shape of the blade, without the need to replace the clamping block, thus saving production costs; Second, the upper and lower pressing mechanisms are controlled by separate oil cylinders, which is suitable for pressing various types of blades and has a stronger pressing force.
