[0030] Embodiment 1

[0031] Refer to the attached Figures 1-5 , an angle steel adaptive root clearing device for a power transmission tower, including a support base 1 and support plates 11 arranged on both sides of the support base 1. A plurality of bi-directional lead screws 12 are arranged between the two support plates 11 on both sides. The bi-directional lead screws 12 are symmetrically arranged in pairs at both ends of the support base 1. An adaptive clamping mechanism 5 is arranged on the bi-directional lead screws 12 to achieve precise clamping of the upper half structure of the angle steel 4;

[0032] The two sides of the support base 1 are slidably connected with a main support 7. A root clearing milling mechanism 8 is arranged on the main support 7 for root clearing treatment of the angle steel 4. A roller seat 2 is arranged on the support base 1. A plurality of V-shaped rollers 3 are arranged in parallel on the roller seat 2. The angle steel 4 is placed on the V-shaped rollers 3.

[0033] The adaptive clamping mechanism 5 includes guide sliders 51 arranged at both ends of two groups of bi-directional lead screws 12. The two sides of the guide sliders 51 are respectively screwed to the two groups of bi-directional lead screws 12. An L-shaped fixture 52 is slidably connected inside the guide slider 51. A tensile spring 53 is connected between the L-shaped fixture 52 and the inner wall of the guide slider 51. The horizontal end of the L-shaped fixture 52 abuts against the end of the angle steel 4. A limit component 56 is arranged at the bottom of the horizontal end of the L-shaped fixture 52. An adjusting device 54 is arranged at the top of the horizontal end of the L-shaped fixture 52 for adjusting the position of the limit component 56 to adapt to the positioning use of the angle steel 4. Inclined surface guide rails 6 are arranged on the mutually remote sides of the two support plates 11. The inclined surface guide rails 6 are slidably connected with the L-shaped fixture 52.

[0034] The root clearing milling mechanism 8 includes a connecting plate 81 fixed between two groups of main brackets 7. A slide bar 82 and a first lead screw 83 are respectively arranged between the two groups of main brackets 7. A tool holder 84 is slidably connected to the connecting plate 81. The tool holder 84 is screwed to the first lead screw 83 and slidably connected to the slide bar 82. A second motor 87 is arranged at the top of the tool holder 84, and the second motor 87 drives the tool assembly to operate.

[0035] The adaptive root clearing milling of the present invention is mainly divided into two steps:

[0036] First, the adaptive clamping movement: The adaptive clamping mechanism 5 is in an open state before work. During work, the angle steel 4 is placed on the V-shaped rollers 3. The 90° angle part on the outer side of the angle steel 4 is in contact with the parallelly arranged V-shaped rollers 3. The motor connected to the bidirectional lead screw 12 is started to drive the bidirectional lead screw 12 to rotate, so that the bidirectional lead screw 12 drives the guide sliders 51 on both sides to approach each other along the axial direction of the bidirectional lead screw 12. The movement of the guide sliders 51 on both sides drives the corresponding L-shaped clamps 52 to move towards each other. Under the action of the tension spring 53, while the two L-shaped clamps 52 approach each other, they move along the inclined plane direction of the inclined plane guide rail 6. When the two L-shaped clamps 52 move to contact the end of the angle steel 4, the two bidirectional lead screws 12 stop running and automatically lock, thereby realizing the precise clamping of the upper half structure of the angle steel 4. The lower half structure is in contact with the 90° outside of the angle steel 4 through multiple parallelly arranged V-shaped rollers 3 to complete the clamping of the lower half structure of the angle steel 4, so as to improve the precise positioning of the angle steel 4 and can be adapted to different models of angle steel 4 for use. There is no need for manual repeated adjustment of the clamping size of the fixture, reducing the difficulty of operating on the angle steel 4 and improving the root clearing efficiency of the angle steel 4; the root clearing milling mechanism 8 performs single or multiple pen milling on the angle steel 4, effectively reducing the wear degree of the tool and ensuring the root clearing quality.

[0037] Refer to Figure 6 , taking the equal-angle steel 4 of model 36 as an example, the side width b of the angle steel 4 is 360 mm, the side thickness d is 35 mm, and the inner arc radius r is 30 mm. The specific clamping process is as follows:

[0038] First, place the 36# angle steel 4 on the V-shaped rollers 3. The motor drives the bidirectional lead screw 12 to rotate, and then drives the two guide sliders 51 to move towards each other from the initial position, driving the two L-shaped clamps 52 to approach each other along the direction of the inclined plane guide rail 6. It is set that the angle between the guide rail of the inclined plane guide rail 6 and the vertical direction is 47.7°. The bidirectional lead screw 12 is single-headed and the pitch is 8 mm. Therefore, if the bidirectional lead screw 12 rotates n circles to achieve clamping, the guide sliders 51 move 8n mm towards each other from the initial position respectively, and then drive the two L-shaped clamps 52 to move 8n mm towards each other respectively. In the triangle NPO, , mm, the L-shaped fixture 52 moves downward in the vertical direction mm. At this time, the two groups of L-shaped fixtures 52 contact and self-lock with the angle steel 4 to complete the clamping; at this time, the angle steel 4 is placed on the V-shaped roller 3, and the V-shaped side of the angle steel 4 is placed at 45° to the horizontal plane. According to the calculation, the distance of the angle steel 4 in the direction perpendicular to the ground at this time is , substituting the No. 36 angle steel 4, according to the calculation H = 254.56 mm, the height that the L-shaped fixture 52 needs to descend is h = 270 - 254.56 = 15.44 mm, the angle of the L-shaped fixture 52 is 47.7°, PO = 15.44 mm, then , so the number of turns of the bidirectional lead screw 12 is n = 14.05 / 8 = 1.75625 turns. Therefore, when the bidirectional lead screw rotates clockwise by 1.75625 turns, the No. 36 angle steel 4 is completed for clamping.

[0039] Second, root clearing milling motion: When the L-shaped fixture 52 clamps the upper end structure of the angle steel 4, the tool assembly is not started at this time and remains at a position away from the root clearing part of the angle steel 4; drive the main bracket 7 to move, drive the root clearing milling mechanism 8 to move to the designated position to prepare for the subsequent root clearing milling, start the first lead screw 83, and the first lead screw 83 drives the tool holder 84 to move to the left along the slide bar 82 and the connecting plate 81 until it moves to the leftmost position to ensure that the tool assembly is in the correct starting position, start the tool assembly, and make the tool assembly start the milling operation; during the milling process, the tool assembly completes multiple root clearing milling of the angle steel 4 through down milling and up milling to ensure the milling accuracy and the processing quality of the angle steel 4.

[0040] After the root clearing milling operation is completed, the motor rotates in reverse, driving the bidirectional lead screw 12 to rotate in the reverse direction, driving the two groups of guide sliders 51 to move away from each other, and the two groups of guide sliders 51 drive the two groups of L-shaped fixtures 52 to move away from the angle steel 4, disengaging the constraint between the L-shaped fixture 52 and the angle steel 4 and completing self-locking through the bidirectional lead screw 12. The multiple groups of parallelly arranged V-shaped rollers 3 are connected by a belt. Start the motor to drive the belt to rotate, so that the V-shaped rollers 3 rotate, and rely on the friction force to drive the angle steel 4 to be discharged from the discharge port, thereby completing the root clearing milling operation of the angle steel 4 and ensuring the quality of the angle steel 4.

[0041] Refer to the appendix Figures 2-3 , as a possible implementation manner of this solution, preferably, a positioning chute 55 is provided on the horizontal end of the L-shaped fixture 52, and the limiting component 56 is slidably arranged along the positioning chute 55.

[0042] The vertical section of the L-shaped fixture 52 is provided with an inclined chute 521, the inclined chute 521 is slidably connected to the inclined guide rail 6, a pulley 522 is installed at the top of the inclined chute 521 through a connecting frame 523, the top of the inclined guide rail 6 is provided with an inclined connecting groove 61, and the pulley 522 is slidably connected to the inclined connecting groove 61.

[0043] The bidirectional lead screw 12 rotates to drive the L-shaped fixture 52 to move. During the process of the L-shaped fixtures 52 approaching each other, the inclined chute 521 is slidably connected to the inclined guide rail 6. At the same time, under the action of the tension spring 53, the pulley 522 is driven to always slide along the inclined connecting groove 61, so as to realize that the L-shaped fixtures 52 approach each other and slide downward along the inclined guide rail 6 to adapt to the use of angle steels 4 of different models, without the need for manual adjustment of the clamping position of the fixture, reducing the operation difficulty for the angle steel 4 and improving the operation efficiency.

[0044] Embodiment 2

[0045] Refer to the attached Figures 3-4 As a possible implementation manner of this solution, preferably, the adjusting device 54 includes fixing seats 541 arranged on both sides of the top of the transverse end of the L-shaped fixture 52. A screw rod 542 is rotatably connected between the two fixing seats 541. A movable support 543 is screwed on the screw rod 542. The movable support 543 is slidably connected to the positioning chute 55. One end of the screw rod 542 is connected to a first motor 544, and the limiting component 56 is fixed on the side of the movable support 543 close to the angle steel 4.

[0046] The limiting component 56 includes a mounting seat 562 fixed on one side of the movable support 543. A pressing plate 563 is rotatably connected inside the mounting seat 562. The pressing plate 563 presses against the bottom of the end of the angle steel 4. A protruding end 561 for restricting the rotation of the pressing plate 563 is arranged on the side of the mounting seat 562 close to the angle steel 4. A limiting spring 564 is connected between the side of the pressing plate 563 away from the angle steel 4 and the movable support 543.

[0047] When it is necessary to adjust the position according to the model of the angle steel 4, the L-shaped fixture 52 moves to contact the end of the angle steel 4 under the action of the bidirectional lead screw 12. The first motor 544 is started, and the first motor 544 drives the screw rod 542 to rotate, thereby driving the movable support 543 to move. The movable support 543 drives the mounting seat 562 to move, so that the mounting seat 562 drives the pressing plate 563 to be adjusted to abut against the outer side of the upper end of the angle steel 4, so that the two pressing plates 563 press the angle steel 4 from both sides, further improving the precise positioning of the angle steel 4 and ensuring the accuracy of subsequent root clearing milling to improve the quality of the angle steel 4 operation. Under the action of the limiting spring 564, the pressing plate 563 can closely adhere to the angle steel 4 and adapt to it.

[0048] Embodiment 3

[0050] Guide ends 13 are provided at the bottoms of the two main brackets 7 on the sides close to each other. The guide ends 13 are slidably connected to the connecting rods on both sides of the support seat 1.

[0051] During the root clearing milling operation, through the cooperation of the first lead screw 83, the main bracket 7 and the guide end 13, the milling cutter disc 9 is moved to the leftmost position, so that the milling cutter disc 9 is located at the correct starting position. The second motor 87 is started, and the milling cutter disc 9 is driven to rotate through the conveyor belt 88, so that the milling cutter disc 9 starts to operate. The second motor 87 drives the second lead screw 85 to rotate, so as to drive the tool holder 86 and the milling cutter disc 9 installed on the tool holder 86 to move downward, and start the milling operation after contacting the root clearing part of the angle steel 4;

[0052] During the milling process, the main bracket 7 controls the milling cutter disc 9 to perform down milling from front to back until one end of the angle steel 4 is processed. The movement of the main bracket 7 can be controlled by a mechanism capable of performing linear reciprocating motion such as a lead screw assembly, a cylinder or an electric push rod. Subsequently, the second motor 87 drives the first lead screw 83 to rotate, so that the tool rest 84 drives the milling cutter disc 9 to move to the right along the slide bar 82, and is adjusted to the set root clearing width to ensure that the milling cutter disc 9 covers the entire root clearing area. At the same time, the second motor 87 controls the second lead screw 85 to rotate, so that the milling cutter disc 9 moves downward to the set root clearing depth. Subsequently, the main bracket 7 is controlled to move in the reverse direction, and the milling cutter disc 9 is driven to perform up milling from back to front, completing multiple root clearing milling operations on the angle steel 4 to ensure the milling accuracy and the quality of the angle steel 4.
