[0002] Wind power generation converts the kinetic energy of wind into electrical energy. Wind energy is a clean, pollution-free, renewable energy source. Due to its pollution-free, renewable, and mature technology, coupled with its vast energy reserves, wind power generation is gaining increasing attention worldwide.

[0003] During the production of wind turbine towers, the rolled components must be grouped and initially welded. During this welding process, the worker who welds the neutral wire generally welds the neutral wire directly to the iron block and then throws it into the unassembled tower. The neutral wire will slide down by gravity as the tower rotates and remain at the bottom of the tower. The disadvantages of this approach are that, first, the neutral wire may slip out of the tube during the rotation of the tube, and secondly, the contact area between the neutral wire and the inner wall of the tower is too large, and the neutral wire is excessively worn by the edge and the inside of the tube during the operation. In order to solve this technical problem, the utility model proposes a device to prevent the line from falling, wear and bending. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a device for preventing line from falling, abrasion and bending;

[0023] It includes a basic bracket 1, a clamping base 2, an anti-channeling blocking structure 3 and a tower 7. The clamping base 2 is arranged above the eccentric central axis of the basic bracket 1. The anti-channeling blocking structure 3 is detachably arranged on one side of the basic bracket 1. An adjustable wheeled support device 4 is movably arranged on the anti-channeling blocking structure 3. The four end corners of the basic bracket 1 are provided with rollers 6 with a diameter greater than the width of the main body of the basic bracket 1. The larger diameter rollers can better offset the overturning moment and make the movement of the device more stable. The basic bracket 1 works on the inner wall of the tower 7.

[0024] The basic bracket 1 includes a connecting plate 101 and a connecting shaft 102. The four end corners of the basic bracket 1 are provided with a certain inward angle of the axis of the roller 6, and the central axis of the basic bracket 1 is an eccentric central axis.

[0025] The clamping base 2 includes a support frame 201, a No. 1 clamping base 202, a No. 2 clamping base 203 and a butterfly screw rod 204. The support frame 201 is arranged at the top of the connecting plate 101, the No. 1 clamping base 202 is arranged at the top of the connecting plate 101, the No. 2 clamping base 203 is movably arranged inside the support frame 201, the butterfly screw rod 204 is rotatably arranged at the top of the No. 2 clamping base 203, and the butterfly screw rod 204 is threadedly connected to the support frame 201, and the clamping base surfaces of the No. 1 clamping base 202 and the No. 2 clamping base 203 are arc surfaces.

[0026] The anti-channeling blocking structure 3 includes a support rod 301 and a blocking frame 302 . A nut 5 is provided on one side of the connecting plate 101 . The support rod 301 is threadedly connected to the nut 5 . The blocking frame 302 is provided at one end of the support rod 301 .

[0027] The adjustable wheeled support device 4 comprises a sliding ring 401 movably arranged outside the support rod 301 and a mounting frame 402 arranged at the bottom end of the sliding ring 401.

[0028] The inside of the support frame 201 is provided with a guide groove 8, and the outside of the second clamping base 203 is provided with two groups of protrusions 9 movably penetrating the inside of the guide groove 8.

[0029] The four end corners of the foundation support 1 are provided with eccentric shafts, and the middle shaft is an eccentric shaft to balance the overturning moment caused by the zero line. The clamping foundation 2 is arranged above the eccentric middle shaft. The clamping operation surface is a curved surface, which can better clamp the line. The anti-channeling blocking structure 3 is connected to the sliding ring 401 of the adjustable wheeled support device 4 on one side of the foundation support 1 by a nut 5, and the adjustable wheeled support device 4 is designed to balance the moment caused by the line. The four end points of the foundation support 1 are provided with moving devices rollers 6. The larger diameter rollers 6 can better offset the overturning moment and make the device move more stably. The clamping foundation 2 is provided with a butterfly type screw rod 204 on the upper surface. The butterfly type screw rod is used for clamping. During the operation process, it is easier to operate. Increasing the pitch of the screw rod will reduce the clamping operation time.

[0030] To solve the problem of zero line sliding in the team operation, we use the rotation of the tower drum during the operation process to offset the advancing angle of the trolley wheel with the zero line. Then during the team operation process, the trolley will always have a tendency to walk into the cylinder through the rotation of the tower drum 7. To fix the relative position of the trolley in the cylinder, we extend the anti-channeling blocking structure 3 outside the cylinder. Under the action of the two designs, the trolley will maintain a relatively static state with the cylinder during the operation process.

[0031] To solve the problem of zero line wear caused by the edge and wall of the cylinder during the team operation process, we use the trolley to move in the cylinder. The rolling of the roller 6 replaces the previous dry friction of the zero line. The rolling of the roller 6 will bring the relative static state of the trolley and the cylinder. The zero line is fixed on the trolley, and the zero line will maintain a relatively static state with the cylinder. At this time, the edge of the cylinder may still wear the zero line. To solve this problem, we pass the zero line through the extended anti-channeling blocking structure 3. Because the zero line has a certain gravity, it will bring a certain overturning force to the trolley. Therefore, a supporting device for the zero line is installed behind the fixing structure.

[0032] To solve the problem of zero line pulling and twisting caused by the rotation of the tower drum 7 during the operation process, this device will always be at the low end of the cylinder wall during the operation process, so it will not pull the zero line. The rotation of the trolley roller 6 will avoid the twisting of the zero line.

[0033] Working principle: the utility model discloses when using, first the line clamping and trolley clamp inside screw butterfly screw rod 204 are tightened, secondly, the trolley is placed in the inner wall of the processing cylinder, and the extended anti-escape blocking structure 3 is close to the cylinder edge and can carry out the welding operation, has the advantages of simple operation, convenient to use, and good use effect.

Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model.
