Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting device for steel structures of electric power transmission towers. Background Art

[0002] An electric power transmission tower is a tall structure used to support overhead transmission conductors in a transmission line. Generally, it is divided into five types according to its shape: wine glass type, cat head type, upper type, dry type, and barrel type. According to its use, there are tension towers, straight towers, corner towers, transposition towers, terminal towers, and crossing towers, etc. All kinds of tower types belong to space truss structures. The whole tower mainly consists of three major parts: tower head, tower body, and tower legs. If it is a guyed tower, a guy wire part is added. Angle steel is one of the most commonly used profiles in electric power transmission towers. Its cross-section is in the shape of an "L", and it is divided into equal-angle steel and unequal-angle steel. It has good mechanical strength and load-bearing capacity, and can withstand various loads on the tower. Usually, it adopts a lattice design and is assembled by multiple angle steel members in a grid form to form a stable tower frame structure, which not only increases the rigidity and stability of the tower, but also can reduce the amount of material used and the self-weight of the tower;

[0003] During cutting, when the angle steel is not restricted at the cutting position and tilts and warps, after straight cutting, the cutting position of the angle steel is prone to errors, and at the same time, the cutting edge is prone to be beveled, affecting the cutting quality.

[0008] A material pressing mechanism, which cooperates with the material conveying mechanism to convey profiles, and the material pressing mechanism is symmetrically installed on the top of the material conveying mechanism along the central axis position of the material conveying mechanism;

[0009] The cam is provided with a plurality of sliding holes, and a plurality of sliding columns are fixedly installed between the plurality of side plates, and the sliding columns are symmetrically installed along the axis center position of the plurality of side plates, and a sleeve plate is slidably installed on the outer side of the sliding columns, and a connecting rod is fixedly installed on the central position of the non-opposite surfaces of the sleeve plates, and the outer side of the connecting rod is slidably adapted to the sliding holes of the side plates. Through the contact between the arc pressure block and the two sides of the angle steel profile, the compression spring is deformed when the angle steel enters, and an elastic force is generated, so that the angle steel is subjected to the same force on both sides, and the cutting center position corresponds to the cutting mechanism. By utilizing the restriction of the sleeve plate by the sliding column, the arc pressure block is further restricted, so that the arc pressure block on the same side contacts the same height of the angle steel profile on the same side, and the angle steel is restricted from warping, and the angle steel is prevented from being offset, resulting in an error in the cutting position. At the same time, by restricting the warping of the angle steel, an inclined surface appears in the cut after cutting, which affects the cutting quality. A spring is fixedly installed between the sleeve plate and the side plate, and a bottom plate is fixedly installed on both sides of the bottom of the sleeve plate, and an arc pressure block is fixedly installed on one end of the bottom plate away from the sleeve plate.

The slider is restricted by the guide rod so that the laser cutting gun can be used horizontally, and the rectangular through groove at the center position of the top of the support plate is used to provide space for the cutting residue to fall during cutting, so that the residue passes through the rectangular through groove and falls to the ground, thereby avoiding the cutting residue from accumulating inside the equipment and affecting the transmission of the angle steel. The outer side of the screw is threadedly connected to the inner wall of the slider, and the laser cutting gun is fixedly installed at the center position of the bottom of the slider.

Groove strips are provided on both sides of the runner. A rubber ring is fixedly installed on the outer side of the runner. Through the rubber ring on the outer side of the runner, when the angle steel is placed, the self-gravity of the angle steel is used to cooperate with the material pressing mechanism to increase the contact pressure, deform the rubber ring, increase the contact area, and increase the friction force with the angle steel, ensuring that the angle steel can be smoothly driven during rotation, avoiding slipping of the angle steel during transmission and causing incorrect cutting positions. Side sliders are slidably installed at the groove strip positions of the runner. Elastic rings are fixedly installed between the side sliders and the convex plates. Outer arc plates are fixedly installed on the outer sides of the side sliders. Through the cooperation of the elastic rings and the side sliders, during the transmission of the angle steel, a certain supporting force is provided for both sides of the bottom of the angle steel to avoid tilting and dropping of the angle steel. At the same time, in cooperation with the material pressing mechanism, the position of the angle steel is restricted to avoid tilting and offset during the transmission of the angle steel, resulting in the angle steel being unable to smoothly enter the cutting position. A rubber cushion strip is fixedly installed at one end of the outer arc plate away from the side slider.

[0013] Preferably, the material pressing mechanism includes a cover plate. The cover plate is symmetrically installed at the top of the support plate along the central axis of the support plate.

The chute block is symmetrically installed along the central axis of the empty groove. A plate groove is provided on the outer side of the chute block. A slide plate is slidably installed at the plate groove position of the chute block. Rubber cushion blocks are fixedly installed on the tops of the slide plates. Through the rubber deformation of the rubber cushion blocks, when the angle steel penetrates, it is compressed and deformed to generate a reaction force, pressing the angle steel downward, and cooperating with the self-gravity of the angle steel to increase the contact pressure between the angle steel and the material conveying mechanism, increasing the friction force during transmission and avoiding slipping of the angle steel. Connecting plates are fixedly installed on both sides of the bottom of the slide plate. Side clamping plates are fixedly installed at the bottoms of the opposite surfaces of the connecting plates. A material pressing wheel is rotatably installed between the side clamping plates. Through the annular groove of the material pressing wheel contacting the angle steel, when the angle steel is tilted, it is restricted by the annular groove to avoid tilting and dropping of the angle steel. At the same time, the rotatably installed material pressing wheel changes the friction force with the angle steel during transmission into rotational friction force, reducing the resistance received by the angle steel during transmission. The material pressing wheels are evenly installed along the axis between the side clamping plates, and annular grooves are provided on the outer sides of the material pressing wheels.

[0014] The present invention provides a laser cutting device for steel structures of power transmission towers, having the following beneficial effects:

[0015] 1. The laser cutting equipment for the steel structure profiles of power transmission towers, through the contact of the arc pressure blocks with both sides of the angle steel profiles, compresses the spring deformation when the angle steel enters, generating elastic force, so that under the same force on both sides of the angle steel, the cutting center position corresponds to the cutting mechanism. By using the restriction of the sliding column on the sleeve plate, and then restricting the arc pressure blocks, the arc pressure blocks on the same side contact the same height on the same side of the angle steel profile, restricting the warping of the angle steel and avoiding the deviation of the angle steel, which may lead to incorrect cutting positions. At the same time, by restricting the warping of the angle steel, the cut surface after cutting shows an inclined plane, affecting the cutting quality.

[0016] 2. The laser cutting equipment for the steel structure profiles of power transmission towers, through the rubber ring outside the runner, when the angle steel is placed, uses the self - gravity of the angle steel to cooperate with the pressing mechanism, increasing the contact pressure, deforming the rubber ring, increasing the contact area, and increasing the friction force with the angle steel, ensuring that the angle steel can be smoothly driven during rotation and avoiding the angle steel from slipping during transmission, resulting in incorrect cutting positions.

[0017] 3. The laser cutting equipment for the steel structure profiles of power transmission towers, through the cooperation of the elastic force ring and the side slider, provides a certain supporting force for both sides of the bottom of the angle steel during the transmission of the angle steel, avoiding the angle steel from tilting and falling. At the same time, cooperating with the pressing mechanism, it restricts the position of the angle steel, avoiding the angle steel from tilting and deviating during the transmission process, resulting in the angle steel being unable to smoothly enter the cutting position.

[0018] 4. The laser cutting equipment for the steel structure profiles of power transmission towers, through the rubber deformation of the rubber cushion block, is compressed and deformed when the angle steel penetrates, generating a reaction force, pressing the angle steel downward, and cooperating with the self - gravity of the angle steel, increasing the contact pressure between the angle steel and the material transmission mechanism, increasing the friction force during transmission, and avoiding the angle steel from slipping.

[0019] 5. The laser cutting equipment for the steel structure profiles of power transmission towers, through the contact of the annular groove of the pressing wheel with the angle steel, when the angle steel is tilted, restricts the angle steel through the annular groove, avoiding the angle steel from tilting and falling. At the same time, the rotationally installed pressing wheel changes the friction force between the angle steel during transmission into rotational friction force, reducing the resistance received by the angle steel during transmission.

[0034] The blank holding mechanism 3 cooperates with the material conveying mechanism 2 to convey profiles, and the blank holding mechanism 3 is symmetrically installed at the top of the material conveying mechanism 2 along the axis center position of the material conveying mechanism 2;

[0035] Sliding holes are provided at the center positions of the opposite surfaces of the side plates 5, and a sliding column 6 is fixedly installed between the side plates 5. The sliding column 6 is symmetrically installed along the axis center position of the side plates 5, and a sleeve plate 7 is slidably installed on the outer side of the sliding column 6. Connecting rods 9 are fixedly installed at the center positions of the non-opposite surfaces of the sleeve plate 7. The sleeve plate 7 is restricted by the sliding column 6 fixedly installed between the side plates 5. When the angle steel enters between the arc pressing blocks 11, through the contact between the side of the angle steel and the arc pressing blocks 11, the arc pressing blocks 11 are pushed to both sides, so that the pressure is transmitted to the spring 8 through the bottom plate 10 and the sleeve plate 7, causing the spring 8 to be compressed and deformed, and the sleeve plate 7 moves to both sides to provide a gap for the entry of the angle steel. The outer side of the connecting rod 9 is slidably adapted to the sliding holes of the side plates 5. A spring 8 is fixedly installed between the sleeve plate 7 and the side plates 5, and bottom plates 10 are fixedly installed on both sides of the bottom of the sleeve plate 7. When the cutting position of the angle steel reaches directly below the cutting mechanism 4, through the elastic force generated by the compression deformation of the spring 8, the two arc pressing blocks 11 on the same side are closely attached to the outer side of the angle steel, and the angle steel is restricted by the elastic force of the spring 8. At the same time, the two springs 8 on both sides apply pressure to the angle steel under the same elastic force, so that the center position of the angle steel corresponds to the cutting center position. At the same time, the arc pressing blocks 11 on the same side contact the same height of the side of the angle steel under the restriction of the sliding column 6 on the sleeve plate 7, so that the angle steel cannot warp. Arc pressing blocks 11 are fixedly installed at the ends of the bottom plates 10 away from the sleeve plate 7.

[0036] The cutting mechanism 4 includes a first motor 41 and a guide rod 42. The output end of the first motor 41 penetrates through the frame body 1 and extends into its interior. The two ends of the guide rod 42 are fixedly connected to both sides of the inner wall of the frame body 1, and the guide rod 42 is symmetrically installed along the axis center position of the frame body 1. When the cutting position of the angle steel reaches, the first motor 41 drives the screw rod 43 to rotate. By using the threaded connection between the screw rod 43 and the slider 44, the slider 44 moves under the restriction of the guide rod 42, and at the same time drives the laser cutting gun 45 to move, so that the laser cutting gun 45 cuts the angle steel. A slider 44 is slidably installed on the outer side of the guide rod 42. The output end of the first motor 41 is fixedly connected with a screw rod 43. The outer side of the screw rod 43 is threadedly connected with the inner wall of the slider 44. A laser cutting gun 45 is fixedly installed at the center position of the bottom of the slider 44

[0037] Second embodiment, on the basis of the first embodiment, please refer to Figures 4 to 6As shown, the material transmission mechanism 2 includes a support plate 201, a rectangular through groove is provided at the center position of the top of the support plate 201, and the rectangular through groove of the support plate 201 is located directly below the laser cutting gun 45, and fixed plates 202 are fixedly installed on both sides of the support plate 201, and the non-opposite surfaces of the fixed plate 202 are fixedly connected to the two sides of the inner wall of the frame 1, and the worker puts the angle steel into the top of the rotating wheel 207 so that the angle of the angle steel is downward, and the second motor 203 drives the pulley 205 to rotate through the belt 204, so that the pulley 205 drives the rotating shaft 206 and the rotating wheel 207 to rotate, and in the process of rotation, the rubber ring 209 on the outside of the rotating wheel 207 contacts the center position of the angle of the angle steel, and cooperates with the material pressing mechanism 3 to increase the friction between the rubber ring 209 and the angle steel, so as to drive the angle steel to move during rotation, and the top of the support plate 201 is symmetrically provided with wheel grooves, and the support plate 20 1 is fixedly installed with a fixing block 214 at the bottom, and the fixing block 214 corresponds to the wheel groove one by one, and a rotating shaft 206 is rotatably installed on the inner wall of the fixing block 214, and a pulley 205 is fixedly installed at one end of the rotating shaft 206. The second motor 203 is fixedly installed at both ends of the bottom of the support plate 201, and the output end of the second motor 203 is transmission-connected with a belt 204. During the movement, it contacts the two sides of the inside of the angle steel through the rubber pad 213, and the pressing mechanism 3 cooperates with the gravity of the angle steel to apply downward pressure. The pressure is transmitted to the side slider 210 through the rubber pad 213 and the outer arc plate 212, so that the side slider 210 compresses the elastic ring 211 to deform, and the elastic force generated by the deformation of the elastic ring 211 is used to provide supporting force on both sides of the inside of the angle steel during the transmission process. The output end of the second motor 203 is transmission-connected with the pulley 205 through the belt 204.

[0038] A rotating wheel 207 is fixedly installed at the center position of the outer side of the rotating shaft 206, convex plates 208 are fixedly installed at the center positions of both sides of the rotating wheel 207, and grooves are opened on both sides of the rotating wheel 207, a rubber ring 209 is fixedly installed on the outer side of the rotating wheel 207, and side sliders 210 are slidably installed in the grooves of the rotating wheel 207, elastic rings 211 are fixedly installed between the side sliders 210 and the convex plates 208, an outer arc plate 212 is fixedly installed on the outer side of the side slider 210, and a rubber pad strip 213 is fixedly installed on the end of the outer arc plate 212 away from the side slider 210.

[0039] The third embodiment is based on the first and second embodiments. Figures 7 to 8As shown in the figure, the blank holding mechanism 3 includes a cover plate 31. The cover plate 31 is symmetrically installed at the top of the support plate 201 along the central axis position of the support plate 201, and empty slots are symmetrically opened on the outer side of the cover plate 31. A chute block 32 is fixedly installed at the top of the cover plate 31. The blank holding wheel 37 contacts the protrusion on the top of the angle steel. When the angle steel penetrates, the angle steel jacks up the blank holding wheel 37 upwards, causing the rubber cushion block 34 to be compressed and deformed. At the same time, a reaction force is generated, pressing the angle steel downwards, increasing the contact pressure between the angle steel and the material conveying mechanism 2. The chute block 32 is symmetrically installed along the central axis position of the empty slot. A plate slot is opened on the outer side of the chute block 32, and a sliding plate 35 is slidably installed at the plate slot of the chute block 32. Rubber cushion blocks 34 are fixedly installed at the tops of the sliding plates 35. Connecting plates 33 are fixedly installed at both sides of the bottom of the sliding plate 35. Side clamping plates 36 are fixedly installed at the bottoms of the opposite surfaces of the connecting plates 33. A blank holding wheel 37 is rotatably installed between the side clamping plates 36. During the transmission process, through the annular groove of the blank holding wheel 37, it contacts the top of the angle steel. Cooperating with the material conveying mechanism 2 during the transmission of the angle steel, the position of the angle steel is positioned and restricted. The blank holding wheels 37 are uniformly installed along the axis between the side clamping plates 36, and an annular groove is opened on the outer side of the blank holding wheel 37.

[0040] During use, the worker places the angle steel profile of the power transmission tower into the material conveying mechanism 2. Through the cooperation of the material conveying mechanism 2 and the blank holding mechanism 3, the angle steel profile is driven to move, so that the angle steel profile moves to directly below the cutting mechanism 4, and the angle steel profile is laser cut by the cutting mechanism 4 to be cut according to the required dimensions.

[0041] When the cutting position of the angle steel reaches directly below the cutting mechanism 4, the sleeve plate 7 is restricted by the sliding columns 6 fixedly installed between the side plates 5. When the angle steel enters between the arc pressing blocks 11, through the contact between the side of the angle steel and the arc pressing blocks 11, the arc pressing blocks 11 are pushed to both sides, so that the pressure is transmitted to the spring 8 through the bottom plate 10 and the sleeve plate 7, causing the spring 8 to be compressed and deformed, and the sleeve plate 7 moves to both sides to provide a gap for the entry of the angle steel. When the cutting position of the angle steel reaches directly below the cutting mechanism 4, due to the elastic force generated by the compression deformation of the spring 8, the two arc pressing blocks 11 on the same side are closely attached to the outer side of the angle steel. The elastic force of the spring 8 is used to restrict the angle steel. At the same time, the springs 8 on both sides apply pressure to the angle steel under the same elastic force, so that the central position of the angle steel corresponds to the cutting center position. At the same time, the arc pressing blocks 11 on the same side, under the restriction of the sliding columns 6 on the sleeve plate 7, contact the same height of the side of the angle steel, so that the angle steel cannot warp.

[0042] In the cutting mechanism 4, when the cutting position of the angle steel reaches, the first motor 41 drives the screw rod 43 to rotate. Using the threaded connection between the screw rod 43 and the slider 44, the slider 44 moves under the restriction of the guide rod 42, and drives the laser cutting gun 45 to move while moving, so that the laser cutting gun 45 cuts the angle steel.

[0043] In the material conveying mechanism 2, the worker places the angle steel on the top of the rotating wheel 207 with the included angle of the angle steel facing downwards. The second motor 203 drives the pulley 205 to rotate through the belt 204, causing the pulley 205 to drive the rotating shaft 206 and the rotating wheel 207 to rotate. During the rotation process, the rubber ring 209 on the outer side of the rotating wheel 207 contacts the central position of the included angle of the angle steel. Cooperating with the material pressing mechanism 3, the friction force between the rubber ring 209 and the angle steel is increased, and the angle steel is driven to move during rotation. At the same time, during the movement process, the rubber cushion strip 213 contacts both sides inside the angle steel, and the material pressing mechanism 3 cooperates with the self-weight of the angle steel to apply pressure downwards. The pressure is transmitted to the side slider 210 through the rubber cushion strip 213 and the outer arc plate 212, causing the side slider 210 to compress the elastic ring 211 and deform. Using the elastic force generated by the deformation of the elastic ring 211, a supporting force is provided on both sides inside the angle steel during the transmission process.

[0044] In the material pressing mechanism 3, the pressing wheel 37 contacts the protrusion on the top of the angle steel. When the angle steel penetrates, the angle steel pushes up the pressing wheel 37, causing the rubber cushion block 34 to be compressed and deformed. At the same time, a reaction force is generated to press the angle steel downwards, increasing the contact pressure between the angle steel and the material conveying mechanism 2. At the same time, during the transmission process, through the annular groove of the pressing wheel 37, it contacts the top of the angle steel, and cooperates with the material conveying mechanism 2 to position and limit the position of the angle steel during the transmission of the angle steel.
