[0029] Example

[0030] Reference Figure 1-Figure 5The utility model provides a technical solution: a special painting hoisting tool for wind turbine base castings, including a hanging dragon frame 1 and a hoisting mechanism 3, and a slide rail 2 is fixedly installed on the inner top of the hanging dragon frame 1, and the hoisting mechanism 3 includes a winding motor 31, and the winding motor 31 is installed at the output end of the winding motor 31. The output end of the winding motor 31 is equipped with a winding roller 311, and a connecting rope 32 is wound around the outside of the winding roller 311, and a ball 321 is installed at one end of the connecting rope 32. Two connecting ropes 32 are installed on the outside of the ball 321, and a round rod 33 is fixedly installed at one end of one of the connecting ropes 32. A cylinder 331 is rotatably installed on the outside of the connecting rope 32, and a circular plate 332 is fixedly installed on one end of the other connecting rope 32.

[0031] In a preferred embodiment, a connecting plate 4 is slidably installed on the slide rail 2, and a winding motor 31 is fixedly installed on the bottom of the connecting plate 4 for controlling the stable reciprocating movement of the winding motor 31. In order to facilitate the control of the movement of the winding motor 31 so as to lift castings placed in different positions, a connecting plate 4 is slidably installed on the slide rail 2, and the winding motor 31 is installed on the connecting plate 4. By controlling the movement of the connecting plate 4, the winding motor 31 can be driven to move, which meets the requirements of use.

[0032] In a preferred embodiment, a mounting hole 5 is provided on the outer surface of the circular plate 332, a circular plate 6 is fixedly mounted on one end of the round rod 33, and a threaded hole is provided on the outer side of the circular plate 6. The circular plate 332 is fixedly connected to the circular plate 6 by bolts. When the casting is lifted, the cylinder 331 is passed through the inside of the casting, and the circular plate 6 on one end of the round rod 33 is fixedly connected to the circular plate 332, and the two traction ropes 322 are closed to facilitate lifting the casting and painting the casting.

[0033] In a preferred embodiment, a baffle 7 is fixedly installed at the top position of the dragon frame 1, and the baffle 7 is respectively installed at the left and right ends of the top of the dragon frame 1. When the device moves the winding motor 31, in order to prevent the connecting plate 4 from falling from the slide rail 2, a baffle 7 is installed at one end of the slide rail 2. Under the action of the baffle 7, the winding motor 31 will be limited to avoid falling from the slide rail 2, so that the device can be used normally.

[0034] When the casting is lifted, in order to ensure stable operation of the casting, a supporting mechanism 8 is installed on the outside of the cylinder 331. The supporting mechanism 8 includes a hollow cylinder 81, a moving rod 82 and a screw 83. The hollow cylinder 81 is fixedly installed on the outer surface of the cylinder 331, and the moving rod 82 is slidably installed inside the hollow cylinder 81, and a bottom plate 9 is installed at the lower end of the moving rod 82. An annular plate 10 is fixedly installed at the upper end of the interior of the hollow cylinder 81 for limiting the bottom plate 9. A rubber pad 11 is fixedly installed on the top of the moving rod 82 for protecting the inner wall of the casting. There are several moving rods 82 and they are evenly arranged at the positions at both ends of the cylinder 331. A circular hole 12 is provided on the outer surface of the moving rod 82, and a screw hole is opened on the outer surface of the hollow cylinder 81, and a screw 83 is provided inside the screw hole, and one end of the screw 83 extends into the inside of the circular hole 12.

[0035] In actual use, in order to ensure that the casting is stably lifted, the control screw 83 is used to adjust the length of the moving rod 82 extending from the inside of the hollow cylinder 81, so that one end of the moving rod 82 is against the inner wall of the casting. By controlling all the moving rods 82 to press against the inner wall of the casting, the screw 83 is then screwed into the inside of the hollow cylinder 81 and extended into the inside of the moving rod 82. In this way, the moving rod 82 is positioned so that it can press against the inner wall of the casting, making the casting stable for use. Moreover, since the cylinder 331 is rotatable, the rotation of the casting can be controlled in actual use, which facilitates the cleaning of the outer surface of the casting, removes external impurities, and improves the painting effect.

[0036] Specifically, the working process or working principle of a special painting hoisting tool for wind turbine base castings is as follows: Since the wind turbine castings are very heavy, when painting the castings, it is necessary to constantly change the painting angle so as to paint the outer surface of the castings. In addition, most existing painting methods use painting robots to paint them, but due to the problem of casting placement, the bottom of the casting cannot be painted, affecting the processing effect of the castings. Therefore, this device is designed to solve this problem.

[0037] The casting can be lifted by this device, and the casting is in a suspended state so that an external painting robot can paint the entire outer surface of the casting, which is easy to use and improves the processing effect of the casting. The specific operation is to connect the external power supply, move the casting to a position directly below the hanging dragon frame 1 through an external mobile device, and then pass the cylinder 331 through the inside of the casting, and extend one end of the cylinder 331 from the inside of the casting. To ensure that the casting is stably lifted, the screw 83 is controlled to adjust the length of the moving rod 82 extending from the inside of the hollow cylinder 81, so that one end of the moving rod 82 is against the inner wall of the casting. By controlling all the moving rods 82 to be against the inner wall of the casting, the screw 83 is screwed into the inside of the hollow cylinder 81 and extended into the inside of the moving rod 82, so as to position the moving rod 82.

[0038] Then the circular plate 332 is installed on the circular plate 6 by bolts to connect the two traction ropes 322 together and pass through the inside of the casting. Then, the winding motor 31 is used to control the winding roller 311 to rotate and reel in the connecting rope 32. As the connecting rope 32 is continuously pulled until the casting is lifted from the ground, the casting can be suspended in the air, and then the traction rope 322 is continued to be reeled in. When the casting is lifted to a suitable position, the reeling of the connecting rope 32 can be stopped, and then the outer surface of the casting can be painted by an external painting robot to facilitate the processing of the casting.

[0039] Since the cylinder 331 rotates secretly on the round rod 33, in actual use, the casting can be rotated according to the position of the casting spraying paint. While stably supporting the inside of the casting, it can also be rotated so that the outer surface of the casting can be cleaned before painting to avoid impurities adhering to its surface, thereby improving the processing effect and meeting the use requirements.

[0040] After the casting is processed, the winding motor 31 can be used to control the winding roller 311 to reverse, so that the casting slowly falls onto a dedicated receiving seat outside, and then the connection point between the two traction ropes 322 is untied to pull the casting out.
