Embodiment

[0037] Please refer to figure 1 , the present embodiment provides a blade spar cap spreading trolley 100 , including a frame 1 , a tension adjusting mechanism 2 and a cloth laminating roller mechanism 3 .

[0038] Such as Figure 1-Figure 7 As shown, in this embodiment, the tension adjustment mechanism 2 includes a tension spring 21, an adjustment swing arm 22 and a tension adjustment assembly 23. One end of the tension spring 21 is fixed to the vehicle frame 1, and the other end is connected to the adjustment swing arm 22. The arm 22 is connected in transmission with the tension adjustment assembly 23, the tension adjustment assembly 23 is rotatably connected with the vehicle frame 1 through the first bearing seat 41, the tension spring 21 exerts a pulling force on the adjustment swing arm 22, and the tension spring 21 can drive the tension adjustment assembly 23 rotates relative to the vehicle frame 1, thereby changing the tension of the cloth (cloth layer) passing through ...

Abstract

The invention relates to a blade beam cap laying trolley, and belongs to the technical field of laying trolleys. A tension spring is detachably connected with an adjusting swing arm, the adjusting swing arm is in transmission connection with a tension adjusting assembly, the tension adjusting assembly is rotatably connected with a frame, a cloth pressing roll swing frame is rotatably connected with the frame, a cloth pressing roll is rotatably connected with the cloth pressing roll swing frame, and a winching assembly is installed on the frame and connected with the cloth pressing roll swing frame; the tension spring can drive the adjusting swing arm to rotate relative to the frame, so that cloth arranged on the tension adjusting assembly in a penetrating mode is tensioned; and the winching assembly is used for driving the cloth pressing roll swing frame to rotate relative to the frame, so that the cloth pressing roll presses the cloth. According to the blade beam cap laying trolley, the tension of the cloth can be conveniently adjusted, the uniformity of the rotating tension of cloth layers can be guaranteed, the flatness of the cloth layers is kept, the internal stress among thecloth layers is eliminated, the condition that the laid cloth layers are lifted up in the cloth laying process is prevented, cloth layer folds are eliminated, and the cloth laying quality and the cloth laying efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of spreading trolleys, in particular to a blade spar cap spreading trolley. Background technique [0002] With the trend of large-scale wind turbine blades, the spar cap, as the main load-bearing part, has higher and higher requirements on its mechanical properties and weight. The conventional carbon fiber perfusion main beam process has the disadvantages of poor carbon fiber wettability and poor process friendliness. Due to the characteristics of the material itself, the carbon fiber prepreg avoids the pouring process and ensures the consistency of the product. [0003] In the process of laying carbon fiber prepreg cloth rolls, the laying trolley is used to improve the laying efficiency. With the existing cloth spreading trolley, the tension control of the prepreg cloth roll is poor, and the laying of the cloth roll is easy to bring up the laid cloth layer, or cause the cloth layer to wrinkle, which affec...
