[0001] The invention relates to the technical field of slope opening devices, in particular to a slope opening device for a corrugated surface at an end of a tower. Background Art

[0002] The diameter of the wind power tower is very large, and steel plates are generally rolled to form. After the steel plates are rolled, the butt surfaces are welded together. Before welding, the butt surfaces need to be sloped. Generally, the butt surfaces of tower welding are straight surfaces. Since the welding length of this butt surface is short, the connection strength of the welding surface is not high. Therefore, the butt surfaces are cut into arc-shaped wavy butt surfaces. There are currently two cutting methods. One is to cut the steel plate into an arc-shaped wavy surface, then slope it, and then roll it; the second is to roll the steel plate first, and then cut the arc-shaped wavy surface at the end of the cylinder. For the second method of cutting the arc-shaped surface at the end of the cylinder, it is more difficult to slope the arc-shaped wavy surface at the end of the cylinder, and the chamfers cut out by workers manually bit by bit are very uneven.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 6 A tower end corrugated surface slope opening device comprises a support frame 1, on which a slope opening component and two groups of first positioning components 5 are symmetrically arranged on both sides of the slope opening component. The two groups of first positioning components 5 can limit the support frame 1 along the axial direction of the tower 24, and an arc line identical to the arc of the tower 24 can be formed between the two groups of first positioning components 5 and the slope opening component. The two groups of first positioning components 5 and the slope opening component have a total of three components, which can determine an arc. One first positioning component 5 is located at the first wave portion 7 of the wave surface of the tower 24, the slope opening component is located at the second wave portion 8 of the wave surface of the tower 24, and the other first positioning component 5 is located at the third wave portion 9 of the wave surface of the tower 24. The slope opening component can move synchronously with the two first positioning components 5, that is, the two groups of first positioning components 5 and one slope opening component each correspond to a wave unit, preferably three continuous wave units. Since the three groups of components are fixed on the same support frame 1, the movement of the two groups of first positioning components 5 and one slope opening component can achieve exactly the same motion trajectory.

[0025] The device limits the support frame 1 along the axial direction of the tower 24 through two groups of first positioning components 5. One first positioning component 5 is located at the first wave portion 7 of the wave surface of the tower 24, the slope opening component is located at the second wave portion 8 of the wave surface of the tower 24, and the other first positioning component 5 is located at the third wave portion 9 of the wave surface of the tower 24. When the two first positioning components 5 move along the first wave portion 7 and the third wave portion 9, the support frame 1 drives the slope opening component to follow the movement, and the slope opening component moves along the second wave portion 8 following the movement of the support frame 1. That is, when the two first positioning components 5 move to the crest of the wave surface, the slope opening component also moves to the crest, and when the two first positioning components 5 move to the trough of the wave surface, the slope opening component also moves to the trough. The movement of the slope opening component is positioned and guided by the two first positioning components 5, so that the difficulty of slope opening on the wave surface at the end of the tower is reduced, and the slope opening shape is more uniform and even.

[0026] The slope opening assembly includes a rotating shaft 3 which is rotatably connected to the support frame 1 and whose axis is arranged radially along the tower 24. A conical milling cutter 4 is installed at the bottom end of the rotating shaft 3. A rotating motor 2 which is fixed to the support frame 1 is connected to the top end of the rotating shaft 3. The rotating motor 2 drives the rotating shaft 3 to rotate, and the conical milling cutter 4 is driven to rotate by the rotating shaft 3. Figure 6 , the chamfer is cut on the wave surface by a conical milling cutter 4.

[0027] refer to Figure 1 , Figure 5 The first positioning assembly 5 includes a first guide rod 13 arranged along the radial direction of the tower 24. The first guide rod 13 is installed on the support frame 1. The first guide rod 13 can abut against the end face of the wave surface of the tower 24. The first guide rod 13 is abutted against the end face of the wave surface of the tower 24 to limit the movement of the support frame 1 along the axial direction of the tower 24. In order to make the movement smoother, the first guide rod 13 includes a first main body rod and a first roller 16 installed at the bottom end of the first main body rod. The axis of the first roller 16 is arranged along the radial direction of the tower 24, and the outer peripheral surface of the first roller 16 can abut against the end face of the wave surface of the tower 24.

[0028] When in use, the support frame 1 is placed on one side of the wave surface of the tower 24, and then a first positioning component 5 is located at the first wave part 7 of the wave surface of the tower 24, the slope opening component is located at the second wave part 8 of the wave surface of the tower 24, and the other first positioning component 5 is located at the third wave part 9 of the wave surface of the tower 24. At the same time, the first roller 16 abuts against the end face of the wave part, and the movement of the support frame 1 to the main body of the tower is limited by the first roller 16. At the same time, the rotating motor 2 is started to rotate the conical milling cutter 4, and then the support frame 1 is held to perform circular motion around the axial direction of the tower, and the support frame 1 is guided and limited by the front and rear two first rollers 16, so that the support frame 1 drives the conical milling cutter 4 to follow the motion, so that the chamfer shape cut by the conical milling cutter 4 is more uniform.

[0029] The support frame 1 includes a first support rod 10 and two second support rods 11. The two second support rods 11 are respectively located at both ends of the first support rod 10. The second support rod 11 is rotatably connected to the first support rod 10 through a connecting piece 17, and the angle between the second support rod 11 and the first support rod 10 can be fixed. The slope opening component is installed on the first support rod 10, and the two first positioning components 5 are respectively installed on the two second support rods 11. The two ends of the first support rod 10 of the device are rotatably connected to the second support rod 11, so that the support angle of the two second support rods 11 can be adjusted. In this way, the positions of the three points of the two first positioning components 5 and one slope opening component can be adjusted. Different three points can determine different curvatures, so that it can adapt to towers of different sizes.

[0030] As an embodiment, the connecting member 17 includes a bolt 22 and a nut 23. The bolt 22 passes through the first support rod 10 and the second support rod 11 and is locked by the nut 23. When the bolt 22 and the nut 23 are loosened, the angle between the first support rod 10 and the second support rod 11 can be adjusted. After the adjustment is completed, the first support rod 10 and the second support rod 11 can be clamped and fixed by the bolt 22 and the nut 23.

[0031] The second support rod 11 is provided with a track 12, and the first positioning assembly 5 includes a first support block 14 and a first guide rod 13. The first support block 14 is slidably connected to the track 12, and the first support block 14 is fixed to the second support rod 11 by a locking bolt, and the first support block 14 can be close to or away from the slope component. The first guide rod 13 includes a first main body rod and a first roller 16 installed at the bottom end of the first main body rod. The first main body rod radially penetrates the first support block 14 along the tower 24, and the two are fixed by a first locking member 15. The axis of the first roller 16 is arranged radially along the tower 24, and the outer peripheral surface of the first roller 16 can abut against the end surface of the wave surface of the tower 24. The first support block 14 is slidably connected to the track 12 to achieve adjustment of the distance position between the slope component and the first positioning assembly 5 to adapt to wave surfaces of different sizes, and the radial height of the first roller 16 can also be adjusted to cope with wave surfaces of different sizes.

[0032] Furthermore, the slope opening device also includes two sets of second positioning components 6, which are symmetrically arranged on both sides of the slope opening component. The two sets of second positioning components 6 can limit the support frame 1 along the radial direction of the tower 24, and the support frame 1 is axially limited by the first positioning component 5, and the support frame 1 is radially limited by the second positioning component 6. Figure 5 Under the joint action of the first positioning assembly 5 and the second positioning assembly 6, the position between the support frame 1 and the tower is made more stable, further improving the uniformity of the slope.

[0033] The second positioning assembly 6 includes a second guide rod 18, which is radially arranged along the tower 24 and installed on the support frame 1. The second guide rod 18 can abut against the outer peripheral surface of the tower 24; the second guide rod 18 includes a second main rod, and the bottom end of the second main rod is rotatably connected to a second roller 20, the axis of the second roller 20 is axially arranged along the tower 24, and the second roller 20 is supported on the outer peripheral surface of the tower 24.

[0034] Of course, since the second positioning assembly 6 needs to move in a circular motion as well as along the axial direction of the tower, the second roller 20 can be configured as a universal roller.

[0035] When using, refer to Figure 5 The support frame 1 is squeezed in the axial direction and radial direction of the tower, and is supported on the end faces of the first wave portion 7 and the third wave portion 9 by the front and rear two first rollers 16 respectively, and is supported on the outer peripheral surface of the tower by the front and rear two second rollers 20, so as to realize the radial positioning and axial positioning of the support frame 1, and then the support frame 1 is rotated around the axis of the tower, and the first positioning component 5 and the second positioning component 6 move around the end faces of the first wave portion 7 and the third wave portion 9 to position and guide the slope opening component, and the tapered milling cutter 4 is used to stably and evenly complete the slope opening and chamfering.

[0036] As an embodiment, the device can be applied to towers with a diameter of 2 meters to 5 meters. The wave surface is preferably similar to an arc surface, and the diameter of each arc is approximately 20 centimeters to 50 centimeters. For example, for a tower with a diameter of 5 meters, the diameter of the arc of the wave surface is approximately 50 centimeters. A slope opening component and two groups of first positioning components 5 are set at a distance of three adjacent wave arc units, and the diameters of the first roller 16 and the second roller 20 are 1 centimeter to 3 centimeters.
