Description

Technical Field

[0001] This utility model relates to the technical field of installation tools for wind turbine components, and in particular to a wind turbine component clamping mold. Background Technology

[0002] Because the mounting bushing of the wind turbine assembly only covers the middle of the wind turbine, the wind turbine often rotates during installation. This rotation can cause deviations during installation, resulting in defective products. If the number of defective products is large, it will affect production. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of existing technologies where the wind turbine rotates during installation, and provides a wind turbine assembly clamping mold that improves the stability of the wind turbine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wind turbine assembly clamping mold, comprising:

[0006] The upper mold is placed on top of the clamping mold;

[0007] The lower mold is placed below the upper mold;

[0008] The groove is placed on the lower end face of the lower mold;

[0009] The mold ejector pin has its lower end placed in a groove, and its upper end passes through the top surface of the groove and is positioned above the lower mold.

[0010] An annular groove is placed on the upper end face of the lower mold, the annular groove surrounds the mold ejector pin, and the annular groove is coaxial with the mold ejector pin;

[0011] An annular pressure plate is placed above the lower mold, and the inner diameter of the annular pressure plate is larger than the inner diameter of the annular groove.

[0012] Several fixing rods are evenly distributed on the upper end surface of the lower mold. The fixing rods are placed around the annular groove. One end of the fixing rod is fixedly connected to the upper end surface of the lower mold. The upper end of the fixing rod passes through the lower end surface of the annular pressure plate and is placed above the annular pressure plate.

[0013] A spring is placed in a groove, with its upper end in contact with the lower end face of the mold ejector pin;

[0014] Slot 1 is placed on the lower end face of the upper mold. Slot 1 is coaxial with the mold ejector pin, and the upper end of the mold ejector pin is placed in slot 1.

[0015] When in use, the impeller to be installed is placed into the annular groove of the lower mold. Then, an annular pressure plate is placed above the impeller and fixed in position with a fixing rod. The weight of the annular pressure plate presses the impeller downward, making it difficult for the impeller to rotate. Next, the bushing is put into the mold ejector pin, and the groove on the upper mold is used to hold the mold ejector pin and press the bushing downward. When encountering impellers with inconsistent heights, the mold ejector pin will also adjust its length under the action of the spring, thereby improving the stability of the impeller.

[0016] Preferably, the fixing rod is provided with a fixing nut, which is placed on the upper end face of the annular pressure plate. The fixing nut is threadedly connected to the fixing rod, and the annular pressure plate is connected to the lower mold through the cooperation of the fixing rod and the fixing nut. The fixing nut can fix the annular pressure plate to the fixing rod, making the annular pressure plate more stable.

[0017] Preferably, the annular pressure plate is provided with a plurality of pressure blocks, which are grouped together and evenly distributed on the upper surface of the annular pressure plate. The lowermost pressure block engages with the upper surface of the annular pressure plate, and the pressure block engages with the adjacent pressure block. The pressure blocks increase the weight of the annular pressure plate, allowing different impellers to be held in place.

[0018] Preferably, the upper surface of the annular pressure plate is provided with several fixing grooves, one fixing groove corresponding to a set of pressure blocks. The lowermost pressure block is placed in the fixing groove and is engaged with the annular pressure plate through the fixing groove. The fixing groove can stabilize the pressure block.

[0019] Preferably, the lower end face of the annular pressure plate is provided with a plurality of flexible rings, which are distributed outward from the center of the annular pressure plate and are fixedly connected to the lower end face of the annular pressure plate. The flexible rings are intended to reduce damage to the wind turbine.

[0020] Preferably, the annular groove contains a plurality of flexible pillars, which are evenly distributed on the outer wall of the annular groove. The cross-sectional shape of the flexible pillars is conical, and the flexible pillars are fixedly connected to the outer wall of the annular groove. The flexible pillars can hold the fan blades in place without damaging them.

[0021] Preferably, the pressure block is provided with a second slot and a locking strip. The second slot is placed on the lower end face of the pressure block, and the locking strip is placed on the upper end face of the pressure block. The locking strip is fixedly connected to the pressure block, and the locking strip corresponds to the second slot. The pressure block is engaged with adjacent pressure blocks through the cooperation of the second slot and the locking strip. The second slot and the locking strip are designed to prevent the stacked pressure blocks from moving arbitrarily.

[0022] The beneficial effects of this utility model are: improving the stability of the wind turbine; the fixing nut can fix the annular pressure plate to the fixing rod, making the annular pressure plate more stable; the pressure block can increase the weight of the annular pressure plate, allowing different wind turbines to be pressed down; the fixing groove can stabilize the pressure block; the soft ring is to reduce damage to the wind turbine; the soft column can hold the wind blades in place without damaging them; the second slot and the locking strip are to prevent the stacked pressure blocks from moving randomly.

On the upper surface of the lower mold 2, the fixing rod 7 is placed around the annular groove 5. One end of the fixing rod 7 is fixedly connected to the upper surface of the lower mold 2. The upper end of the fixing rod 7 passes through the lower surface of the annular pressure plate 6 and is placed above the annular pressure plate 6. The spring 13 is placed in the groove 4. The upper end of the spring 13 is in contact with the lower surface of the mold ejector pin 3. The slot 14 is placed on the lower surface of the upper mold 1. The slot 14 is coaxial with the mold ejector pin 3. The upper end of the mold ejector pin 3 is placed in the slot 14.

[0029] like Figures 1 to 3As shown, a fixing nut 8 is provided on the fixing rod 7. The fixing nut 8 is placed on the upper end face of the annular pressure plate 6. The fixing nut 8 is threadedly connected to the fixing rod 7. The annular pressure plate 6 is connected to the lower mold 2 through the cooperation of the fixing rod 7 and the fixing nut 8.

[0030] like Figure 1 and Figure 2 As shown, the annular pressure plate 6 is provided with several pressure blocks 9. The pressure blocks 9 are grouped into several groups, and the groups of pressure blocks 9 are evenly distributed on the upper end surface of the annular pressure plate 6. The lowermost pressure block 9 is engaged with the upper end surface of the annular pressure plate 6, and the pressure block 9 is engaged with the adjacent pressure block 9.

[0031] like Figure 3 As shown, the upper surface of the annular pressure plate 6 is provided with several fixing grooves 10, one fixing groove 10 corresponds to a set of pressure blocks 9, the lowermost pressure block 9 is placed in the fixing groove 10, and the lowermost pressure block 9 is engaged with the annular pressure plate 6 through the fixing groove 10.

[0032] like Figure 3 As shown, a number of soft rings 12 are provided on the lower end surface of the annular pressure plate 6. The soft rings 12 are distributed outward with the center of the annular pressure plate 6 as the axis, and the soft rings 12 are fixedly connected to the lower end surface of the annular pressure plate 6.

[0033] like Figure 2 and Figure 3 As shown, a number of flexible pillars 11 are provided in the annular groove 5.
