Description

Technical Field

[0001] The utility model belongs to the technical field related to mechanical engineering, and particularly relates to a blade turning machine. Background Art

[0002] A blade turner is a specially designed mechanical device used to turn large blades during the manufacturing and maintenance of wind turbine blades. This equipment is usually used for post-processing procedures of blades, such as grinding, shaping, painting, etc., to ensure that the blades can be handled safely and accurately. The design of the blade turner takes into account the size, weight and stability requirements of the blades during the turning process to improve work efficiency and ensure operational safety. Traditional ground turning equipment cannot meet the needs of turning large-sized blades and occupies a large area, which can easily cause damage to the blades and has low production efficiency. The aerial turning machine is small in size and flexible in operation, avoiding damage to the blades during the turning process. The turning efficiency is 5 times that of traditional ground turning. Since the turning with a sling can adapt to wind turbine blades of various sizes, a blade turner is indispensable. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The utility model provides Figure 1-5 The blade turning machine shown is a blade turning machine, comprising a transmission main body case 4 and a lifting ring 1 arranged at the upper end of the transmission main body case 4; a side plate 6 is installed at the inner wall position of the transmission main body case 4; a wiring pipe 2 is installed on the inner side of the transmission main body case 4 and below the lifting ring 1, and an anti-slip connection device 3 is installed on the inner side of the transmission main body case 4 and below the wiring pipe 2; a roller 5 is installed on the inner side of the transmission main body case 4 and below the anti-slip connection device 3, and the outer side of the roller 5 is fixed. A sling 11 is located below the transmission case 4. An electronic control system box 8 is located at the front right side of the transmission case 4, with an indicator light 7 located slightly to the left of the upper end of the box. A wired control jack 9 is located on the right side of the box, and a power supply 10 is connected to the left side of the box. A motor is located inside the transmission case 4, connected to the electronic control system box 8 via a connecting wire inside a wiring conduit 2. The box is then connected to an external power source via the power supply 10. The installation of the blade turning mechanism reduces the size of the machine, improves production efficiency, and reduces the failure rate.

[0031] like Figure 1 and Figure 2As shown, in order to reduce the volume, improve production efficiency and reduce the failure rate, when using the blade turning machine, first use a crane to lift the equipment 1.5M above the ground, then pass the sling 11 through the roller 5, then connect the power supply 10 to the external power supply, and then turn the equipment left and right to check the direction indicator light 7 on the electronic control system box 8. The red indicator light 7 will light up according to the direction of rotation. After the detection is completed, the sling 11 passes through the root of the blade and connects the sling 11 connecting device. Adjust the sling 11 connecting device to the appropriate position, and then slowly lift the blade. The lifting speed should be slow to avoid frequent left and right rotation and large shaking. After lifting to the appropriate height, press the remote control button to realize the left and right rotation of the blade. When switching to left and right rotation, you must wait for one action to stop completely before performing the next action. Frequent and continuous operation of the left and right rotation button is prohibited to avoid damage to the speed change mechanism. Through the setting of the blade turning machine, the volume is reduced, the production efficiency is improved, and the failure rate is reduced, thereby solving the damage to the blade caused by traditional flipping.

[0032] A reinforcing belt 12 is provided at the inner side of the sling 11, a second annular placement groove 16 is provided at the outer wall position of the reinforcing belt 12, a strong rubber layer 17 is provided at the inner position of the annular placement groove, a first annular placement groove 15 is provided at the inner wall position of the reinforcing belt 12, an anti-slip belt 13 is provided at the inner position of the annular placement groove, and an anti-slip film 14 is provided at the inner wall position of the anti-slip belt 13. By arranging the reinforcing belt 12, the anti-slip belt 13 and the anti-slip film 14, not only the friction and anti-slip performance of the belt are improved, but also the bearing performance of the belt is enhanced.

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to improve the friction, anti-skid performance and bearing performance of the belt, when using the blade turning machine, the anti-skid film 14 is first applied to the surface of the anti-skid belt 13, and then the anti-skid belt 13 is glued to the inside of the first annular placement groove 15, so that the anti-skid belt 13 is installed on the inner wall of the reinforcement belt 12, and then the strong adhesive layer 17 is glued to the inside of the second annular placement groove 16, so that the strong adhesive layer 17 is installed on the outer wall of the reinforcement belt 12, and then the reinforcement belt 12 and the sling 11 are connected through the strong adhesive layer 17, so that the reinforcement belt 12 is installed on the inner side of the sling 11. When the reinforcement belt 12 passes through the root of the blade, the setting of the anti-skid film 14 and the anti-skid belt 13 increases the friction between the reinforcement belt 12 and the blade, thereby preventing the blade from slipping when turning over. Now, through the setting of the reinforcement belt 12, the anti-skid belt 13 and the anti-skid film 14, not only the friction and anti-skid performance of the belt are improved, but also the bearing performance of the belt is enhanced.

[0034] The anti-slip belt 13 and the first annular placement groove 15 are both provided with multiple anti-slip belts 13, and the thickness of the multiple anti-slip belts 13 is greater than the thickness of the first annular placement groove 15. The anti-slip film 14 is formed by evenly applying belt wax on the anti-slip belt 13 to form a protective film. The anti-slip film 14 increases the friction of the belt and prevents the anti-slip belt 13 from slipping. The anti-slip belt 13, the reinforcing belt 12 and the belt are all made of rubber material. The belt and the reinforcing belt 12 are connected by a strong adhesive layer 17. The strong adhesive layer 17 is made of cyanoacrylate compounds. These compounds can quickly polymerize when exposed to moisture such as moisture in the air to form high-strength polymers, thereby achieving a fast and strong bonding effect. The setting of the strong adhesive layer 17 enhances the stability of the connection between the belt and the reinforcing belt 12.

[0035] like Figure 2 、 Figure 3 and Figure 5 As shown, in order to enhance the stability of the connection between the belt and the reinforcing belt 12, when using the blade turning machine, the anti-slip film 14 is first applied to the surface of the anti-slip belt 13, and then the anti-slip belt 13 is glued to the inside of the first annular placement groove 15, so that the anti-slip belt 13 is installed on the inner wall of the reinforcing belt 12, and then the strong adhesive layer 17 is glued to the inside of the second annular placement groove 16, so that the strong adhesive layer 17 is installed on the outer wall of the reinforcing belt 12, and then the reinforcing belt 12 is connected to the sling 11 through the strong adhesive layer 17, so that the reinforcing belt 12 is installed on the inner side of the sling 11. Through the setting of the strong adhesive layer 17, the stability of the connection between the belt and the reinforcing belt 12 is enhanced.
