Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a blade mounting and positioning device for wind turbine equipment, comprising: The positioning assembly includes a receiving flange 101, a blade root flange 102, a C-shaped frame 103, and positioning blocks 104. The receiving flange 101 and the blade root flange 102 are movably connected to the top of one end of the C-shaped frame 103, and the positioning blocks 104 are movably connected to both sides of the C-shaped frame 103. The receiving flange 101 and the blade root flange 102 are movably connected between the positioning blocks 104. The easy-to-disassemble component includes an L-shaped block 201, a threaded groove 202, a wing screw 203, a slot 204, and a lever 205. The top of both ends of the C-shaped frame 103 is fixedly connected to the L-shaped block 201. The threaded groove 202 is opened through the L-shaped block 201. The wing screw 203 is movably connected in the threaded groove 202. One end of the wing screw 203 is movably connected to the positioning block 104. The receiving flange 101 has slots 204 on both sides. One end of the positioning block 104 is fixedly connected to the lever 205. The lever 205 movably engages with the slot 204. The receiving flange 101 is fixedly installed at the pitch bearing, and the blade is fixedly installed in the middle of the blade root flange 102. The C-shaped frame 103 and the two positioning blocks 104 form a three-point limit, thereby achieving effective positioning of the receiving flange 101 and the blade root flange 102. The setting of the L-shaped block 201 provides a guarantee for the opening of the threaded groove 202. The threaded groove 202 and the wing screw 203 work together to push the positioning blocks 104 at both ends toward the receiving flange 101, while making the locking rod 205 firmly inserted into the locking groove 204, realizing a stable connection between the receiving flange 101 and the positioning blocks 104. Then, the connected blade root flange 102 is positioned, and the wing screw 203 is rotated in the opposite direction to ensure that the locking rod 205 on the positioning block 104 is disengaged from the locking groove 204. Then, the C-shaped frame 103 is moved downward, which can realize that the C-shaped frame 103 and its connecting parts are disengaged from the receiving flange 101 and the blade root flange 102.

[0018] The positioning component also includes an arc-shaped positioning groove 105, and the C-shaped frame 103 has an arc-shaped positioning groove 105; the positioning block 104 has an arc-shaped clamping and limiting end. The opening of the arc-shaped positioning groove 105 and the setting of the arc-shaped structure of the clamping and limiting end of the positioning block 104 enable the C-shaped frame 103 and the positioning block 104 to fit against the bottom and side ends of the receiving flange 101 and the leaf root flange 102, further improving the positioning and installation effect.

[0019] The length of lever 205 is equal to the depth of slot 204; The dimensional arrangement of the above components ensures that the positioning block 104 can smoothly contact the receiving flange 101 and the side end of the blade root flange 102.

[0020] Working principle: The receiving flange 101 is fixedly installed at the designated position of the pitch bearing. The middle part of the blade root flange 102 is pre-fixed to the blade to be installed, ensuring that the connection between the two is firm and without looseness. The C-shaped bracket 103 is fastened to the bottom of the receiving flange 101, so that the arc-shaped positioning groove 105 on the C-shaped bracket 103 fits against the bottom end of the receiving flange 101, initially defining the position of the device. The wing screw 203 on the L-shaped block 201 is rotated. Using the thread engagement between the threaded groove 202 and the wing screw 203, the positioning blocks 104 on both sides of the C-shaped bracket 103 are pushed towards the flange. During this process, the locking rod 205 at one end of the positioning block 104 gradually aligns with the locking groove 204 on both sides of the receiving flange 101 until the locking rod 205 is fully inserted into the locking groove 204 (because the length of the locking rod 205 is consistent with the depth of the locking groove 204, it ensures that the positioning block 104 fits exactly against the side end of the flange). At this time, the C-shaped bracket 103 is fully engaged. The C-frame 103 and two positioning blocks 104 form a three-point limiting structure, firmly limiting the receiving flange 101. Then, the blade root flange 102 is moved between the C-frame 103 and the positioning blocks 104 until the blade root flange 102 contacts the receiving flange 101, completing the installation and positioning. Then, bolts are used to firmly connect the blade root flange 102 and the receiving flange 101. After the blade and hub are installed, the wing screw 203 is rotated in the opposite direction to move it away from the positioning blocks 104. Then, the positioning blocks 104 at both ends are pulled, and the locking rod 205 is simultaneously disengaged from the locking groove 204. After the locking rod 205 is completely out of the locking groove 204, the C-frame 103 is moved downward, so that the C-frame 103 and the connected positioning blocks 104 and other components are completely disengaged from the receiving flange 101 and the blade root flange 102, completing the disassembly of the device. This step can avoid the blade breakage caused by the vibration generated by the forceful disassembly.

[0021] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The dual-limiting guide assembly includes a strip guide groove 301 and a T-shaped guide rod 302. The strip guide groove 301 is opened at the bottom of the L-shaped block 201. The T-shaped guide rod 302 is fixedly connected to the bottom of the positioning block 104. The T-shaped guide rod 302 is slidably connected in the strip guide groove 301. The T-shaped guide rod 302 slides in the middle area of ​​the C-shaped frame 103. The T-shaped guide rod 302 and the strip guide groove 301 work together to effectively limit the vertical movement of the positioning block 104.

[0022] The dual-limiting guide assembly also includes a rectangular plate 303, which is fixedly connected to one side of the top of the C-shaped frame 103. The rectangular plate 303 is located on the side of the positioning block 104. The dual-limiting guide assembly also includes a circular guide groove 304 and a cylindrical guide rod 305. The circular guide groove 304 is opened through the rectangular plate 303. The cylindrical guide rod 305 is fixedly connected to the side of the positioning block 104. The cylindrical guide rod 305 is movably connected in the circular guide groove 304. The rectangular plate 303 provides a guarantee for the opening of the circular guide groove 304. The cylindrical guide rod 305 and the circular guide groove 304 work together to effectively limit the horizontal movement of the positioning block 104, thereby ensuring the smooth movement of the positioning block 104 and avoiding the shaking and deviation of the positioning block 104 during the movement, which indirectly speeds up the movement rate of the positioning block 104.

[0023] Working principle: During the movement of the positioning block 104, the T-shaped guide rod 302 moves synchronously along the strip guide groove 301, and the cylindrical guide rod 305 moves synchronously in the circular guide groove 304. This step can achieve efficient limiting of the movement of the positioning block 104 and ensure the smooth movement of the positioning block 104.
