Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and specifically refers to a laser cutting device for steel structure profiles of power transmission towers. Background Art

[0002] Power transmission towers are indispensable infrastructure in the power transmission system, mainly used to support and connect transmission lines to ensure efficient power transmission. Power transmission towers are mainly composed of steel structure profiles such as angle steel, I-beams, and seamless steel pipes, which are assembled and welded after cutting. Angle steel towers are power transmission towers mainly assembled from cut angle steel.

[0003] Existing laser cutting devices for angle steel profiles mainly use adjustable square clamping ports for clamping and positioning and feeding. However, after clamping and positioning the angle steel in this way, it is impossible to automatically identify the arrangement state of the angle steel, and it is difficult to determine the accurate position and direction of the two side plates of the angle steel. When laser cutting, the distance between the nozzle of the laser cutter and the side plate of the angle steel cannot be determined, resulting in poor cutting effects and easy formation of slag residues. On the other hand, when the laser cutter cuts the angle steel, it is necessary to frequently control the rotation of the angle steel so that the nozzle is directly opposite the side plate of the angle steel, making the operation of the cutting process more troublesome and inconvenient, and the operation difficulty higher. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to invent a laser cutting device for steel structure profiles of power transmission towers, which is suitable for cutting angle steel, can automatically feed, clamp and position the angle steel in a fixed state with the fold angle facing up, and at the same time can make the laser cutter move along an inverted V-shaped track, so that the nozzle always maintains a perpendicular and equal distance from the side plate of the angle steel, facilitating the cutting of the angle steel.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Combined with the attached Figure 1 As shown, a laser cutting device for steel structure profiles of power transmission towers includes a feeding module 2, a cutting adjustment module 1, an automatic feeding module 3, etc. Specifically: Combined with the attached Figure 1 and the attached Figure 2As shown in the figure, the feeding module 2 includes a feeding rail 21 arranged horizontally in the front-back direction. A feeding base 22 is provided on the left side of the feeding rail 21, and a loading base 23 and a receiving base 24 are slidably arranged in the front-back direction. Among them, the loading base 23 is arranged on the front side of the feeding base 22, and the receiving base 24 is arranged on the rear side of the feeding base 22. Position adjustment modules 7 are respectively arranged horizontally in the front-back direction on the front and rear sides of the feeding base 22 of the feeding rail 21. The position adjustment module 7 includes a position adjustment motor 71 and a position adjustment screw rod 72 connected to the drive shaft of the position adjustment motor 71. The loading base 23 and the receiving base 24 are respectively threadedly sleeved on the corresponding position adjustment screw rods 72. Clamping modules 4 are respectively arranged in the feeding base 22, the loading base 23 and the receiving base 24. A group of position adjustment modules 7 are erected at the rear end of the feeding rail 21, and a fixed-distance baffle 25 driven by the position adjustment module 7 is slidably arranged up and down. A height-limiting plate 231 is arranged on the loading base 23. The bottom of the height-limiting plate 231 is adapted to the upward-facing angle steel fold angle and is arranged corresponding to the top fold angle position of the angle steel after being clamped by the clamping module 4.

[0029] In the above description, the loading base 23 and the receiving base 24 respectively slide back and forth along the feeding rail 21 through the position adjustment module 7. After the angle steel is clamped on the loading base 23 by the clamping module 4, the loading base 23 moves backward to send the angle steel into the clamping module 4 of the feeding base 22. After one end of the angle steel is cut, the receiving base 24 moves forward to clamp the angle steel to prevent it from falling after both ends are cut, and transfer it after cutting. At the same time, by clamping the angle steel with the receiving base 24 and abutting the fixed-distance baffle 25 against one end of the angle steel, the length of the angle steel can be measured in the reverse direction, so as to conveniently position and cut the other end of the angle steel suspended in the air, and effectively reduce the length of the cutting waste at the end of the angle steel and the allowance required for clamping. During the process of the receiving base 24 transferring the angle steel, the fixed-distance baffle 25 slides down to make way for the angle steel to leave.

[0030] Combined with the attached Figure 2 、attached Figure 7 、attached Figure 8 、attached Figure 9As shown, the material clamping module 4 includes mounting seats 41 respectively arranged in the feeding seat 22, the loading seat 23 and the receiving seat 24. A square through groove arranged in the front-rear direction is provided on the mounting seat 41, and a corner of the square through groove is arranged directly upward. An upright plug 411 is provided at the bottom of the square through groove. A clamping seat 44 is arranged in the mounting seat 41. The clamping seat 44 is slidably arranged up and down on the plug 411 through plug slots 441 provided on the front and rear sides. A material clamping spring 412 and a clamping hydraulic rod 45 are arranged between the bottom and the mounting seat 41. Four inner clamping rollers 43 are rotatably arranged at the top, and the inner clamping rollers 43 are respectively arranged parallel to the corresponding side walls above the square through groove, and are alternately arranged in sequence from front to back, left to right. An outer clamping roller 42 in contact with the corresponding inner clamping roller 43 is rotatably arranged in the square through groove of the mounting seat 41. The driving shafts of the rotating shafts of some of the outer clamping rollers 42 are connected to the driving shaft of a feeding motor 421 arranged on the mounting seat 41. A pressing plate 451 is arranged at the telescopic end of the clamping hydraulic rod 45, and the pressing plate 451 is slidably arranged in a pressing plate groove 442 formed in the clamping seat 44.

[0031] In the above description, the clamping seat 44 is lifted by the material clamping spring 412, and the inner clamping roller 43 is in contact with the corresponding outer clamping roller 42. After the angle steel enters between the inner clamping roller 43 and the corresponding outer clamping roller 42, the clamping hydraulic rod 45 extends and the pressing plate 451 abuts against the top of the pressing plate groove 442, so that the angle steel is tightly clamped and limited between the inner clamping rollers 43 and the outer clamping rollers 42, and is fixed in the state with the folded angle facing upward at the same time. After the feeding motor 421 is started, the corresponding outer clamping roller 42 rotates, so that the angle steel moves back and forth in the material clamping module 4. When it is necessary to separate between the outer clamping roller 42 and the inner clamping roller 43, the clamping hydraulic rod 45 is controlled to contract, and after the pressing plate 451 slides down to the bottom of the pressing plate groove 442, the clamping seat 44 is pulled down to separate between the outer clamping roller 42 and the inner clamping roller 43.

[0032] Combined with attached Figure 1 、attached Figure 3 、attached Figure 4 As shown, a gantry 8 is arranged at the rear side of the feeding seat 22, and the gantry 8 is arranged on the left side of the conveying track 21. A cutting adjustment module 1 is arranged inside, a laser cutter 6 is installed on the cutting adjustment module 1, and a cutting base 5 is arranged below. The cutting adjustment module 1 includes a folding angle track module 11, a transverse transmission module 12, a cutting distance adjustment module 13 and a height measurement module 14.

[0033] In the above description, after the cutting adjustment module 1 measures the distance from the folding angle of the angle steel through the height measurement module 14, the laser cutter 6 is kept perpendicular to and at a fixed distance from the two side plates of the angle steel through the folding angle track module 11 and performs cutting. At the same time, through the transverse transmission module 12, it smoothly moves and automatically turns in the left-right direction along a route parallel to the two side plates of the angle steel, and the distance between the nozzle of the laser cutter 6 and the two side plates of the angle steel is adjusted through the cutting distance adjustment module 13.

[0034] Combined with the attached Figure 3 , the attached Figure 4 , the attached Figure 5 As shown, the angled rail module 11 includes a positioning plate 111 that slides back and forth on the gantry 8. A pair of parallel angled rails 112 and a triangular notch are provided at the bottom of the positioning plate 111. The angled rails 112 are symmetric and perpendicular on both sides, and the top angled part is a smooth arc-shaped L-shaped chute structure (the center of the smooth arc is located at the top angled part of the angle steel). A directional sleeve 113 is provided at the rear side of the positioning plate 111. The directional sleeve 113 is perpendicular to the angled rails 112, and a pair of directional sliders 114 are provided on the front side wall. The directional sliders 114 are respectively slidably arranged in the corresponding angled rails 112.

[0035] Combined with the attached Figure 3 , the attached Figure 5 As shown, a set of left-right horizontal adjustment modules 7 are provided at the rear side of the positioning plate 111, and a driving slide base 121 driven by the adjustment module 7 slides left and right at the top. A driving block 122 is rotatably arranged on the directional sleeve 113, and a set of folding rods 123 arranged to fold back and forth are hinged between the top of the driving block 122 and the bottom of the driving slide base 121.

[0036] In the above description, start the adjustment motor 71 of the corresponding adjustment module 7, and the driving slide base 121 slides left and right on the positioning plate 111. At the same time, drive the driving block 122 to slide left and right along the angled rails 112 through the folding rods 123. During the process, the folding rods 123 fold and extend following the distance between the driving slide base 121 and the driving block 122 up and down. And because the distance between the two directional sliders 114 is fixed, and the two angled rails 112 are parallel to each other, the directional sleeve 113 always remains perpendicular to the angled rails 112 and automatically turns after passing through the top bending part.

[0037] Combined with the attached Figure 3 , the attached Figure 4 , the attached Figure 5 As shown, the cutting distance adjustment module 13 includes a lifting seat 133 slidably arranged on the two side walls of the gantry 8 and a fixed-distance rod 131 arranged below the positioning plate 111. One lifting seat 133 is driven by the adjustment module 7 arranged vertically on the gantry 8. The shape of the fixed-distance rod 131 is as shown in the attached Figure 5As shown, both ends thereof are slidably arranged on the two side lifting seats 133 in the front and rear directions respectively, and one end is driven by an adjustment module 7 arranged along the front and rear directions on the other lifting seat 133. A positioning slot 132 is fixed at the other end. One side edge of the positioning plate 111 is slidably arranged in the positioning slot 132. An inverted V-shaped slide rail 135 is arranged on the fixed-distance rod 131 corresponding to the folding-angle slide rail 112. An installation rod 134 is slidably arranged in the orientation sleeve 113. A fixed-distance slider 136 slidably arranged on the V-shaped slide rail 135 is arranged on the installation rod 134. The laser cutter 6 is installed on the fixed-distance slider 136.

[0038] In the above description, the lifting seat 133 moves up and down through the adjustment module 7 on the gantry 8, and the fixed-distance rod 131 moves up and down below the positioning plate 111, driving the installation rod 134 to slide in the orientation sleeve 113, and the laser cutter 6 moves along with the installation rod 134, so as to adjust the distance between the nozzle of the laser cutter 6 and the side plate of the angle steel. Moreover, the fixed-distance rod 131 and the positioning plate 111 move back and forth through the adjustment module 7 on the lifting seat 133, thereby driving the laser cutter 6 to move back and forth to cut the angle steel.

[0039] Combined with Fig. Figure 5 、Fig. Figure 6 As shown, the height measurement module 14 includes a positioning tube 141 vertically installed at the top of the fixed-distance rod 131. A measurement rod 142 and a pressing block 145 are respectively slidably arranged in the positioning tube 141, and a pressure sensor 144 is embedded at the top. A resisting block 143 is arranged at the bottom of the measurement rod 142. A measurement spring 146 is arranged between the top and the pressing block 145, so that the pressing block 145 abuts against the pressure sensor 144, and the bottom of the resisting block 143 is adapted to the top folding angle of the angle steel.

[0040] In the above description, the lifting seat 133 moves down through the adjustment module 7 on the gantry 8, causing the fixed-distance rod 131 to drive the positioning tube 141 to move down. After the bottom of the resisting block 143 abuts against the top folding angle of the angle steel, the pressing block 145 is pressed through the measurement spring 146, and the pressure is obtained through the pressure sensor 144. Finally, the distance between the fixed-distance rod 131 and the top folding angle of the angle steel is measured through the pressure change value of the pressure sensor 144.

[0041] Combined with Fig. Figure 1 、Fig. Figure 10 、Fig. Figure 13As shown in the figure, the automatic feeding module 3 is arranged on the front side of the gantry 8 and includes a lifting feeding module 32 disposed directly below the feeding base 23. A centering module 34 is provided at the top of the lifting feeding module 32, and a turning module 33 and a bracket 31 are arranged on the left side. There are four brackets 31 arranged along the front and back, and connecting telescopic rods 37 are respectively arranged between the two outer brackets 31 and the adjacent brackets 31. The turning module 33 is arranged between the two middle brackets 31. Conveyor tracks 35 are respectively arranged on the two outer brackets 31, and limit baffles 36 are respectively arranged on the brackets 31 at the right ends of the two conveyor tracks 35.

[0042] In the above description, after the angle steel is placed on the conveyor track 35 and moves to the right through the conveyor track 35, and when both ends are respectively abutted against the limit baffles 36, it slides on the conveyor track 35. The rightmost bottom of its bottom is lifted by the turning module 33, and under the action of the conveyor track 35, the angle steel is turned to the left. After being turned to the state where the fold angle is upward, the bent part is lifted by the turning module 33, and the angle steel is transferred to the lifting feeding module 32 between the centering modules 34 by the turning module 33. After being centered and clamped by the centering module 34, it is lifted by the lifting feeding module 32 to the rear side of the feeding base 23, and the feeding base 23 moves backward, so that the angle steel is clamped in the clamping module 4 of the feeding base 23 in the state where the fold angle is upward.

[0043] Combined with attached Figure 10 、attached Figure 12 、attached Figure 13 As shown in the figure, the lifting feeding module 32 includes a pair of fixed frames 321 arranged on the right side of the bracket 31. The two fixed frames 321 are arranged parallel to each other along the front and back, and a connecting telescopic rod 37 is arranged between them to facilitate the adjustment of the front and back distance. The inner sides of the two fixed frames 321 are respectively provided with a feeding frame 322 that slides up and down, and a feeding telescopic rod 323 is vertically arranged between the feeding frame 322 and the corresponding fixed frame 321. A centering module 34 is arranged at the top of the feeding frame 322, including centering clamping rods 341 that slide left and right on the top surface of the feeding frame 322, and centering telescopic rods 343 arranged along the front and back on the opposite surfaces of the two feeding frames 322. A pair of centering clamping rods 341 are respectively arranged on the two feeding frames 322 in a left-right mirror image, and the two pairs of centering clamping rods 341 on the right side are connected together by a linkage telescopic rod 344 arranged horizontally along the front and back. The bottom parts of the centering clamping rods 341 are respectively hinged with centering pull rods 342, and the other ends of the centering pull rods 342 are respectively hinged with the other ends of the centering telescopic rods 343 on the same side.

[0044] In the above description, control the centering telescopic rod 343 to extend, and the two pairs of centering clamping rods 341 respectively make relative movements in the left-right direction driven by the centering pull rods 342 to center and clamp the angle steel. Then control the feeding telescopic rod 323 to extend, and the angle steel moves up with the feeding frame 322 until it abuts against the bottom of the height limit plate 231. Then the feeding base 23 moves backward, and the angle steel is clamped by the clamping module 4.

[0045] Combined with the attached Figure 10 , attached Figure 11 , attached Figure 13 As shown in the figures, the material turning module 33 includes a material turning box 337 and a material turning rod 331. A material turning motor 332 is arranged on the material turning box 337, and an elliptical chute 338 is arranged outside the material turning motor 332. One end of the material turning rod 331 is vertically provided with a support telescopic rod 333. A horizontal chute 334 is arranged at the bottom of the support telescopic rod 333, and it is slidably arranged left and right in the horizontal chute 334. The other end of the material turning rod 331 is provided with an L-shaped rod 335. The top of the L-shaped rod 335 is connected to the material turning rod 331. A transmission telescopic rod 336 is rotatably arranged on the horizontal section and is slidably arranged in the elliptical chute 338. The other end of the transmission telescopic rod 336 is connected to the drive shaft of the material turning motor 332.

[0046] In the above description, the material turning rod 331 moves in the up and down and left and right directions through the support telescopic rod 333 and the horizontal chute 334, and keeps the vertical section of the L-shaped rod 335 at the bottom vertical. When the material turning motor 332 is started, the horizontal section of the L-shaped rod 335 rotates along the elliptical chute 338 driven by the transmission telescopic rod 336, thereby driving the material turning rod 331 to perform a circular motion along an elliptical closed route, and passing through point A on the conveyor track 35 to the left of the limit baffle 36 during the rising process, jacking up the angle steel at point A, and point B on the top surface of the loading rack 322 between the centering modules 34. Specifically: If the angle steel is not in the state of the folded corner facing up, the rightmost side of its bottom is jacked up by the material turning rod 331 passing through point A, and under the action of the conveyor track 35, it continues to move to the right, so that the angle steel is turned to the left until it is turned to the state of the folded corner facing up; If the angle steel is in the state of the folded corner facing up, its right side plate is jacked up by the material turning rod 331 passing through point A, and under the action of the conveyor track 35, it continues to move to the right, and the material turning rod 331 gradually slides to the bottom of the folded corner of the angle steel, thereby jacking up the entire angle steel and transferring it to point B on the lifting loading module 32 in the state of the folded corner facing up.

[0047] When using the present invention for laser cutting of steel structural profiles of power transmission towers, place the angle steel on the conveyor track 35 of the automatic loading module 3. After the angle steel is turned by the turning module 33 to a state with the folded angle facing upwards, it is transferred by the turning module 33 to the top surface of the loading rack 322 between the centering modules 34. Control the centering telescopic rod 343 to extend, and the two pairs of centering clamping rods 341 respectively perform centering clamping on both ends of the angle steel. Then control the loading telescopic rod 323 to extend, raise the angle steel until it abuts against the height limiting plate 231. The loading seat 23 moves backward along the material conveying rail 21, and the angle steel is clamped in the clamping module 4 of the loading seat 23 with the folded angle facing upwards. Then, after the angle steel is transferred to the clamping module 4 of the feeding seat 22 by the loading seat 23, laser cutting is performed on the angle steel at the rear side of the feeding seat 22. During the cutting process, the laser cutter 6 measures the distance between the fixed-distance rod 131 and the top folded angle of the angle steel through the height measurement module 14, slides and turns along the folded angle slide rail 112 through the folded angle track module 11, maintains a perpendicular and fixed distance from both side plates of the angle steel, and adjusts the distance between the nozzle of the laser cutter 6 and both side plates of the angle steel through the cutting distance adjustment module 13. After one end of the angle steel is cut, the waste material falls on the cutting base 5, and the receiving seat 24 moves forward to clamp one end of the angle steel, and then cuts the other end of the angle steel to prevent the angle steel from falling or the remaining material at the other end from being insufficient. After both ends of the angle steel are cut, it is transferred and left through the receiving seat 24.
