Description

Technical Field

[0001] This invention relates to the field of laser cutting machine equipment technology, and in particular to a transportable factory-type laser cutting machine and laser cutting method. Background Technology

[0002] In the construction field, H-beams are in great demand for steel structure construction, deep foundation pit support and large formwork support systems due to their good compressive strength, stiffness and connectability. Currently, most H-beams are cut and transported to the construction site, which takes a long time.

[0003] Traditional frame and box-type laser cutting equipment often adopts a horizontal and vertical straight-line arrangement with one in front and one behind. Due to the long length of a single H-beam, the size of the matching conveyor frame is also very large. This straight-line loading area layout makes the entire equipment have an excessively long longitudinal span, occupy a huge area, and is not easy to move. For construction sites or mobile sheds with limited land and space, this seriously restricts the application of laser cutting technology. In addition, the narrow loading layout limits the operating radius of the lifting equipment on the construction site when coordinating loading, which can easily cause logistics conflicts, thereby reducing material flow efficiency and affecting the overall progress of the project. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a factory-type laser cutting machine and a laser cutting method.

[0005] The technical solution of the present invention is achieved through the following scheme: a handling factory-type laser cutting machine, including a container, a processing unit, L-shaped legs and a transverse transfer table, wherein the processing unit is arranged in the inner cavity of the container, the processing unit includes a movable laser cutting head, a plurality of L-shaped legs are arranged on the outside of the bottom of the side opening of the container, and the transverse transfer table is used to transfer the H-beams at the position of the L-shaped legs to the position of the processing unit. A receiving assembly is provided between adjacent L-shaped support legs. The receiving assembly includes a base, a support plate rotatably connected to the base, and an electromagnet installed on the bottom surface of the support plate. A V-shaped and angle-adjustable receiving groove is provided between the two support plates arranged in pairs. After the H-beam is placed in the receiving groove at a 90-degree angle, the two pairs of support plates rotate downwards synchronously. During the process, the magnetic attraction of one electromagnet to the first bottom plate of the H-beam is greater than the magnetic attraction of the other electromagnet to the first cavity of the H-beam, which is used to drive the H-beam to rotate into an I-shaped position. The top surface of the L-shaped support leg is provided with a friction-reducing wheel; the support plate can be lowered until the H-shaped steel is pressed onto the friction-reducing wheel and slides along the L-shaped support leg to the position of the transverse transfer platform.

[0006] Through the above technical solutions, by highly integrating the processing unit, transverse transfer table and auxiliary unit into the container, and by using the transverse transfer table in conjunction with the external support frame and protective frame for lateral transverse loading, a mobile laser cutting operation platform is created, which enables the equipment to be transported and redeployed as a whole on the construction site.

[0007] Preferably, when the H-beam is placed at an angle in the receiving groove at 90 degrees, the horizontal top surface of the base is perpendicular to the diagonal of the H-beam, and the weight of the left and right sides of the H-beam is equal. The container side opening is hinged with a protective frame, and the protective frame has several through-leg grooves arranged in an array.

[0008] Preferably, the bottom surfaces of the two support plates are respectively hinged to the telescopic ends of the fourth and fifth linear actuators, and the other ends of the fourth and fifth linear actuators are both hinged to the base. The receiving component also includes a third linear actuator, the telescopic end of which is fixedly mounted with a base, and the third linear actuator is suspended on the side wall of the L-shaped support leg.

[0009] Preferably, the top surface of the L-shaped support leg is inclined upward at the end away from the container.

[0010] Preferably, the L-shaped support leg is provided with a flipping frame at its end, and the receiving component and the flipping frame are arranged in an alternating array. The flipping frame includes a rotating plate and a support frame. The rotating plate is rotatably mounted on the support frame by a drive motor. The support frame is fixedly mounted on the telescopic end of the sixth linear drive. The material-bearing surface of the rotating plate has a baffle protruding outward. The rotating plate is generally horizontally L-shaped.

[0011] Preferably, the transverse transfer platform includes a movable base and a receiving platform. The movable base is slidably installed inside the container via drive wheels. A plurality of first linear actuators are provided on the top surface of the movable base near the protective frame. The receiving platform is slidably installed on the top surface of the movable base via a plurality of first linear actuators. The telescopic ends of the first linear actuators are bolted to the protruding blocks on the side wall of the receiving platform. An auxiliary support plate is screwed onto the top surface of the protruding blocks. The other end of the auxiliary support plate overlaps the top surface of the first linear actuators.

[0012] Preferably, the top surface of the movable base is fixedly installed with several abutment columns near the processing unit, and the top surface of the material receiving platform is detachably arrayed with several sword grids.

[0013] Preferably, the top surface of the material receiving platform is provided with two adjustable-spacing limiting plates for securing H-beams. Each limiting plate includes a movable grid and a sword grid, which are arranged in parallel. A slag-collecting groove is opened on the material receiving platform. The movable grid is slidably installed in the slag-collecting groove via a second linear actuator. The second linear actuator is fixedly installed on the side of the material receiving platform away from the first linear actuator. The telescopic end of the second linear actuator passes through the material receiving platform and is connected to the movable grid.

[0014] The laser cutting method of the transport-type laser cutting machine includes the following steps: S1. The H-beam is hoisted and placed into the receiving trough using lifting equipment; S2. The receiving component drives the H-beam to rotate until it is placed in an I-shape; S3, H-beams fall onto the L-shaped support legs and slide to the side opening of the container; S4, H-beams are rotated to form an H-shape and fastened to the transverse transfer platform; S5. The transverse transfer table moves the H-beam to the processing unit position.

[0015] As a preferred option, step S4 specifically includes the following material receiving and feeding steps: S41. The transverse transfer platform moves to the side opening position of the container; S42, The movable grid is close to the sword grid and fits against the side wall; S43. The tilting frame drives the H-beam to rise and then rotates until the H-beam is fastened to the outer periphery of the sword grid and the movable grid. S44. The movable grid moves away from the sword grid to the inner wall of the flange plate of the H-beam near the processing unit.

[0016] In summary, the present invention has the following beneficial effects: 1. This invention integrates the processing unit, the transverse transfer platform, and the auxiliary unit into a container, and creates a mobile laser cutting platform by using the transverse transfer platform in conjunction with the external support frame and the protective frame for lateral transverse loading. This allows the equipment to be transported and redeployed as a whole on the construction site.

[0017] 2. The two support plates arranged in a V-shape form a wider receiving area, allowing users to place the H-beam into the receiving groove without precise alignment. The H-beam then slides under its own weight to fit the receiving groove, reducing the difficulty of operation for users and improving the convenience of construction.

[0018] 3. When the support plates rotate, they can control the originally tilted H-beams to rotate into an I-shape. When the two support plates rotate synchronously, the two electromagnets respectively target different parts of the H-beams. By utilizing the principle of magnetic difference, the H-beams in both left-tilted and right-tilted states can automatically rotate into an I-shape. This makes the invention highly compatible and simplifies the operation steps for users. Users do not need to manually adjust the orientation of the first cavity of the H-beam when lowering it.

[0019] 4. In traditional technology, machine vision technology is needed to identify the orientation of the first cavity, and then two different mechanical structures are used to drive the H-beam to rotate in different directions, so that it is placed in an I-shape. However, this invention utilizes the principle of magnetic difference, which greatly simplifies the mechanical structure. Only one mechanical structure is needed to achieve rotation of H-beams in two different states in different directions, and it has high reliability and low cost.

[0020] 5. The friction-reducing wheel is used to reduce the friction of the H-beam sliding on the L-shaped support leg; the H-beam is pressed into the friction-reducing wheel in an H-shape to avoid jamming and improve the smoothness and efficiency of the H-beam's movement (the friction-reducing wheel can only be installed intermittently, and if the H-beam is pressed into it in an H-shape, there will be a jamming problem).

[0021] 6. The H-beam is rotated to an I-shape, then slid to the side opening position, and then hooked onto the transverse transfer table in an H-shape using a flipping frame. The limit plate then positions and levels the H-beam, and finally moves the H-beam to the processing unit position. All of this is achieved mechanically, with a high degree of automation and standardization, reducing the need for manpower.

[0022] 7. By using L-shaped outriggers to support the support assembly, a relatively large distance can be maintained between the support assembly and the side wall of the container. During hoisting, the swaying H-beams are less likely to collide with the container, thus avoiding impact damage.

[0023] 8. The nested layout of the sixth linear actuator utilizes the steel sidewalls of the lifting support legs as a natural protective surface, enhancing the anti-tipping and anti-bending rigidity of the linear actuator when vertically lifting heavy objects. Through the baffle and the "L"-shaped tilting frame, the lifting support legs rigidly abut and limit the movement at the initial position. Combined with the electromagnetically braked and locked drive motor, triple protection is achieved when the H-beam slowly slides to the end, completely preventing the steel from becoming unstable and falling.

[0024] 9. Select the optimal feeding method based on the on-site construction conditions, the precision of the lifting equipment, and the manpower configuration, which greatly improves the equipment's adaptability to the on-site environment and operational flexibility. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein. Therefore, the invention is not limited to the specific embodiments disclosed in the following specification. The invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1: A transportable factory-type laser cutting machine, such as Figures 1-7As shown, the container includes a container 1, a processing unit 2, L-shaped support legs 3, and a transverse transfer table 4. The processing unit 2 is located inside the container 1 and includes a movable laser cutting head 23. Several L-shaped support legs 3 are located on the outer side of the bottom of the side opening of the container 1. The transverse transfer table 4 is used to transfer the H-beams 101 at the position of the L-shaped support legs 3 to the position of the processing unit 2. An auxiliary unit 13 is also provided at one end of the container 1. The transverse transfer table 4 is located between the processing unit 2 and the protective frame 12. The transverse transfer table 4 is smaller than the width of the protective frame 12. The bottom of the container 1 near the protective frame 12 has a mounting wall with a detachable array on the mounting wall. The container 1 is equipped with several L-shaped outriggers 3, preferably five. A protective frame 12 is hinged to the side opening of the container 1. Several through-leg grooves are arranged on the protective frame 12. The lower hinged end of the protective frame 12 is not hinged to the bottom of the container 1, but is at a certain distance from the bottom of the container 1. This distance is the mounting wall. The mounting wall has screw holes to provide the mounting base for the subsequent L-shaped outriggers 3. The container 1 is equipped with corner fittings that cooperate with hooks and wire ropes. The auxiliary unit 13 includes a cooling and temperature control unit, such as an industrial chiller, an air supply and purification unit, a dust removal and smoke exhaust unit, and a power supply unit, such as a voltage stabilizer and a transformer, located at one end of the container 1.

[0030] like Figure 1 and Figure 2 As shown, the middle of container 1 is the core processing area; the other end is the control area, such as the controller 21 and the operator's station. Container 1 has an auxiliary area door and a control area door. By opening them, one can enter the corresponding area inside container 1 for control and daily maintenance. The control area door is located at the end of container 1 away from the auxiliary unit 13, while the auxiliary area door is located on the side of container 1 away from the protective frame 12 and close to the auxiliary unit 13.

[0031] like Figure 4 As shown, the top surface of the L-shaped support leg 3 is flush with the bottom surface of the inner cavity of the container 1, and several L-shaped support legs 3 are respectively opposite to the bottom rollers of the transverse transfer table 4. The L-shaped support legs 3 ensure that the transverse transfer table 4 can slide out for receiving materials.

[0032] One side of container 1 is replaced by a corrugated plate with a wavy line shape and a protective frame 12. The lower part of the protective frame 12 is hinged to the container body. When container 1, where the laser cutting machine is located, needs to be transported, the protective frame 12 remains vertical. The upper end of the protective frame 12 is pinned to the container body. The through-leg groove provides a precise passage for the installation of L-shaped support legs 3, ensuring a stable connection with the installation wall of container 1 without damaging the integrity of the protective frame 12. The protective frame 12 can be flipped down and opened to form a safety protection boundary for outdoor operations.

[0033] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when the vertical L-shaped support leg 3 is used, the transverse transfer platform 4 includes a movable base 41 and a receiving platform 42. The movable base 41 is slidably installed inside the container 1 via drive wheels, which are rotatably installed at the bottom end of the movable base 41. Several rollers are also installed on the movable base 41 to provide stable movement support. Several first linear actuators 421 are provided on the top surface of the movable base 41 near the protective frame 12. The receiving platform 42 is slidably installed on the top surface of the movable base 41 via several first linear actuators 421. The drive wheels are precisely driven by servo motors. A cable chain 411 is provided on the side of the movable base 41, and a wheel support track is provided on the bottom surface of the container 1, the end face of which is connected to the top surface of the L-shaped support leg 3. The movable base 41 can extend outwards, and the wheel support provides a groove for guiding the rollers and drive wheels at the bottom of the movable base 41. The rollers can run directly and smoothly on the top surface of the flush L-shaped support leg 3. The material support platform 42 is stacked on the top surface of the movable base 41. The top surface of the movable base 41 has a slide rail. The material support platform 42 is driven by two first linear actuators 421, one on the left and one on the right, and slides on the top surface of the movable base 41. The telescopic end of the first linear actuator 421 is bolted to the protruding block on the side wall of the material support platform 42. An auxiliary support plate 102 is screwed to the top surface of the protruding block. The other end of the auxiliary support plate 102 overlaps the top surface of the first linear actuator 421. The auxiliary support plate 102 can support the H-beam 101 with a larger width. The workers can choose the best installation method.

[0034] Several abutment posts 43 are fixedly installed on the top surface of the movable base 41 near the processing unit 2. The abutment posts 43 are screwed to the end of the movable base 41. The first linear driver 421 pushes the support table 42 to make the H-beam 101 abut against the abutment posts 43, thereby forcing the sides of the H-beam 101 to be in the same reference plane to ensure the accuracy of laser cutting. Several sword grids 422 are detachably arrayed on the top surface of the support table 42. When the abutment posts 43 are used, the sword grids 422 can be added or removed according to the width of the H-beam 101. The sword grids 422 are screwed onto the support table 42.

[0035] By setting the abutment column 43 to achieve physical leveling, and combining the first linear actuator 421 to independently slide and fine-tune the material receiving platform 42, the problem of twisting or inaccurate positioning of long H-beams 101 under harsh outdoor working conditions is effectively protected. The first linear actuator 421 can be an electric actuator, pneumatic actuator, hydraulic actuator, electro-hydraulic actuator, or servo electric cylinder. Two first linear actuators 421 are synchronously connected.

[0036] In transport mode, the protective frame 12 rotates and retracts, locking the area door, and the L-shaped support legs 3 are disassembled and stored to meet the standard logistics transport dimensions of container 1. In construction mode, the L-shaped support legs 3 are installed in an array to provide strong external load support. Together with the protective frame 12, a temporary outdoor processing workshop with high safety and high load-bearing capacity is constructed, ensuring the overall stability of H-beam 101 during the loading and cutting process.

[0037] like Figure 5 and Figure 6 As shown, the processing unit 2 includes a controller 21, a moving crossbeam 22, and a laser cutting head 23. The moving crossbeam 22 is slidably installed on the bed 11 inside the container 1 via parallel guide rails 111. The moving crossbeam 22 is generally inverted "L" shape. The bed 11 is provided with two spaced parallel guide rails 111. The moving crossbeam 22 can move along the two parallel guide rails 111. The moving crossbeam 22 adopts a vertical folding type, which is an inverted "L" shaped cantilever, which makes room for side loading, i.e., side loading of the protective frame 12.

[0038] A vertical transmission mechanism 24 is slidably mounted on the moving crossbeam 22. The laser cutting head 23 is movably mounted on the vertical transmission mechanism 24. The transverse transfer table 4 is located directly below the transverse section of the moving crossbeam 22. The moving crossbeam 22 drives the laser cutting head 23 to move laterally. The vertical transmission mechanism 24 can drive the laser cutting head 23 to move up and down. The laser cutting head 23 is a five-axis laser. It should be noted that the automatic and overall displacement of the laser cutting head 23 are existing technologies, such as the moving crossbeam 22 and the vertical transmission mechanism 24 on it.

[0039] The transverse transfer table 4, auxiliary unit 13, moving crossbeam 22 and laser cutting head 23 are all connected to the controller 21 via communication.

[0040] Working principle: The staff checks whether the protective frame 12 has been pinned and fixed, and whether the doors of each area are closed and locked. Then, the container 1 is hoisted onto the truck bed for overall transportation to the construction site. Unload container 1, open the protective frame 12, install vertical L-shaped support legs 3 on the mounting wall of container 1, and transfer H-beam 101 from the H-beam 101 storage area of ​​the construction site using lifting equipment; like Figure 4 As shown, the servo motor controls the drive wheel, causing the movable base 41 to slide outward. The movable base 41 is driven by the drive wheel to move the rollers at the end to the top surface of the vertical L-shaped support leg 3. The drive wheel at the end of the movable base 41 will not exceed the wheel support track. This is the maximum sliding distance of the movable base 41. The first linear actuator 421 pulls the material receiving platform 42 to slide outward on the top surface of the movable base platform 41 until it slides out of the horizontal projection area of ​​the container 1, ensuring that the H-beam 101 will not collide with the container 1 when loading. When the lifting equipment is hoisting, the H-beam 101 is manually adjusted to be hoisted in an H-shape. When the H-beam 101 is placed on the sword grid 422 of the support platform 42, manual fine-tuning is performed to ensure that the H-beam 101 is placed stably. The servo motor is started by the controller 21, and the drive wheel drives the moving base platform 41 to move back to the processing core area inside the container 1. If there is a lateral deviation of the H-beam 101, the extension end of the first linear drive 421 is extended to push and drive the support platform 42 to slide laterally on the moving base platform 41 so that the H-beam 101 on it abuts against the abutment column 43, thereby leveling it.

[0041] Example 2: Figures 8-21 As shown, after the H-beam 101 is placed in an inclined position in the 90-degree receiving groove, the two pairs of support plates 312 rotate downwards synchronously. During the process, the magnetic attraction force of one electromagnet 313 on the first base plate 103 of the H-beam 101 is greater than the magnetic attraction force of the other electromagnet 313 on the first cavity 104 of the H-beam 101, which is used to drive the H-beam 101 to rotate to be placed in an I-shape.

[0042] Compared to Embodiment 1, the top surface of the L-shaped support leg 3 is provided with a friction-reducing wheel 32; the support plate 312 can be lowered until the H-shaped steel 101 is pressed onto the friction-reducing wheel 32 and slides along the L-shaped support leg 3 to the position of the transverse transfer platform 4.

[0043] The top surface of the L-shaped support leg 3 is inclined upward at the end away from the container 1, forming a slope with an angle of 4%. This not only gives the H-beam 101 the initial kinetic energy to slide towards the container 1, but also ensures that the H-beam 101 will not hit the machine body or cause the tilting frame 33 to fail to stop due to excessive sliding speed when it is placed.

[0044] The H-beam 101 is composed of two first base plates 103 and one web plate, wherein the two first base plates 103 and the web plate form two concave first cavities 104.

[0045] like Figure 19 and Figure 20 As shown, the top surface of the material receiving platform 42 is provided with two adjustable spacing limit plates for clamping the H-beam 101. The limit plates include a movable grid 424 and a sword grid 422. The sword grid 422 is fixedly installed on the top surface of the material receiving platform 42 near the first linear driver 421. The movable grid 424 and the sword grid 422 are arranged in parallel. The H-beam 101 is finally covered on the movable grid 424 and the sword grid 422.

[0046] A slag-collecting groove 425 is formed on the material receiving platform 42. A movable grid 424 is slidably installed in the slag-collecting groove 425 via a second linear actuator 423. The movable grid 424 has the same height and length as the sword grid 422. Both ends of the movable grid 424 are integrally formed with protrusions. Corresponding sliding grooves are formed on the two side walls of the inner cavity of the slag-collecting groove 425. The protrusions and sliding grooves are adapted to each other, thereby providing precise guidance for the lateral reciprocating sliding of the movable grid 424 and preventing it from deviating during the material pushing process. The second linear actuator 423 is fixedly installed on the side of the material receiving platform 42 away from the first linear actuator 421. The telescopic end of the driver 423 passes through the material receiving platform 42 and is connected to the movable grid 424. The end of the second linear driver 423 is embedded in the bottom support plate of the movable grid 424. By controlling the lateral extension and retraction of the second linear driver 423, the movable grid 424 can be driven to move smoothly along the slag receiving groove 425 and the slide, thereby pulling one side wall of the H-beam 101 for leveling. In addition to serving as the receiving and running track of the movable grid 424, the slag receiving groove 425 is also used to collect the molten metal slag that falls in during the laser cutting process, making it convenient for workers to clean. Manual cleaning of slag is carried out at regular intervals to prevent waste slag from getting stuck in the movable grid 424.

[0047] Because the end of the second linear actuator 423 penetrates the side wall of the receiving platform 42 and is embedded in the bottom support plate of the movable grid 424, and the slag receiving groove 425 is smaller than the receiving platform 42, when the H-beam 101 is received by the receiving platform 42, the telescopic end of the second linear actuator 423 will not be directly pressed by the H-beam 101, thus avoiding damage and reducing its service life.

[0048] The material receiving platform 42 has a driver support plate protruding on the side away from the first linear driver 421, and the second linear driver 423 is installed on it. The second linear driver 423 adopts a small, short-stroke servo electric cylinder, which minimizes the physical size of the equipment's lateral extension while ensuring thrust, thus optimizing the overall space utilization inside the container 1.

[0049] The second linear actuator 423 enables dual grid support of the dynamic active grid 424 and the sword grid 422. The sliding mechanism enables dynamic leveling and support during the flipping and feeding of H-beam 101. The slag receiving groove 425 can effectively collect the molten metal slag generated during laser cutting.

[0050] like Figure 11 , Figure 13 , Figure 15 , Figure 16 , Figure 17 and Figure 18As shown, a receiving assembly 31 is provided between adjacent L-shaped support legs 3. The receiving assembly 31 includes a base 311, a support plate 312 rotatably connected to the base 311, and an electromagnet 313 installed on the bottom surface of the support plate 312. A V-shaped and angle-adjustable receiving groove is provided between the two support plates 312 arranged in pairs. The bottom surfaces of the two support plates 312 are respectively hinged to the telescopic ends of the fourth linear actuator 3121 and the fifth linear actuator 3122. The other ends of the fourth linear actuator 3121 and the fifth linear actuator 3122 are both hinged to the base 311.

[0051] The receiving component 31 also includes a third linear actuator 3111, the telescopic end of which is fixedly mounted with a base 311, and the third linear actuator 3111 is suspended on the side wall of the L-shaped support leg 3.

[0052] The side wall of the L-shaped support leg 3 is welded with an L-shaped hanging plate and a support plate to form a triangular stable state. The third linear actuator 3111 is fixedly installed on the hanging plate. The base 311 is convex in shape and is composed of a mounting plate and a mounting block. The mounting block is fixedly installed at the center of the mounting plate and is integrally set. Two support plates 312 are rotatably installed on the mounting block. Electromagnets 313 are installed on the non-material-bearing surface of the support plates 312. The base 311 is made of non-magnetic stainless steel. The two electromagnets 313 are located in the center of the non-material-bearing surface of the two support plates 312. One support plate 312 is connected to the fourth linear actuator 3111. Linear actuator 3121 is connected to the mounting plate, and another support plate 312 is connected to the mounting plate through the fifth linear actuator 3122. The non-telescopic ends of the fourth linear actuator 3121 and the fifth linear actuator 3122 are both hinged to the mounting plate, one on the left and one on the right, so as to drive the two support plates 312 to rotate respectively. The two support plates 312 are pushed by the two linear actuators. In the working state, the angle between the two plates is set at 90 degrees. When the support plate 312 is at the top dead point, which is the highest position, the height of the bottom of the receiving trough is higher than the top surface of the L-shaped support leg 3 and the top surface of the friction reduction wheel 32.

[0053] The third linear actuator 3111 pushes the L-shaped support leg 3 to receive the H-beam. No fine-tuning is required; the H-beam 101 is simply hoisted into the V-shaped receiving area formed by the two support plates 312 in a conventional "I-beam" configuration. When the H-beam 101 is placed at an angle in the 90-degree receiving groove, the horizontal top surface of the base 311 is perpendicular to the diagonal of the H-beam 101, and the weight on both sides of the H-beam 101 is equal. There is no need for frequent manual adjustments to the material's posture in the high-risk hoisting area. After being lowered, the H-beam 101 will inevitably exhibit one of two non-standard postures on the two support plates 312: tilting to the right or left. At this point, regardless of the state, the flange of the H-beam 101 will inevitably come into contact with one of the support plates 312. Once in contact, the high-strength magnet located in the center of the non-material-bearing surface of the support plate 312 will immediately generate a strong penetrating magnetic attraction force, instantly adsorbing and locking the inclined side edge of the H-beam 101 onto the support plate 312, completing the initial posture grasping. Then, when the two support plates 312 slowly rotate to the horizontal, the H-beam 101 will rotate with it to form an I-shaped state. Then, the third linear actuator 3111 will reset, and finally place the I-shaped H-beam 101 onto the L-shaped support leg 3, and then slide due to the friction reduction wheel 32 and the gentle slope.

[0054] The third linear actuator 3111 can be an electric actuator, pneumatic actuator, hydraulic actuator, electro-hydraulic actuator, or servo electric cylinder. Since the number of L-shaped legs 3 that need to be installed on the receiving component 31 is two, the third linear actuator 3111 is also preferably two, and they are set synchronously.

[0055] The initial working state of 90 degrees is a fixed value for the extension of the linear actuator obtained by manual experiment. The fourth linear actuator 3121 and the fifth linear actuator 3122 are both preferably servo electric cylinders.

[0056] like Figure 12 and Figure 14As shown, a tilting frame 33 can be provided at the end of the L-shaped support leg 3. There are three L-shaped support legs 3 with the tilting frame 33 installed. The supporting component 31 and the tilting frame 33 are arranged in an alternating array. The two L-shaped support legs 3 with the supporting component 31 are also arranged in an alternating array. The tilting frame 33 includes a rotating plate 331 and a support frame 332. The rotating plate 331 is rotatably mounted on the support frame 332 via a drive motor 333. The support frame 332 is fixedly mounted on the telescopic end of the sixth linear actuator 334. The end of the support leg 3 near the container 1 is embedded with a sixth linear actuator 334. A drive motor 333 is mounted on the support frame 332. The drive motor 333's shaft is connected to a rotating plate 331. The shaft of the drive motor 333 passes through the support frame 332 and is fixedly connected to the rotating plate 331. The shaft and support frame 332 are connected by bearings. A baffle 3311 protrudes from the end of the material-bearing surface of the rotating plate 331. The rotating plate 331 is generally horizontally L-shaped, used to support the edge of the sliding H-beam 101. Rigid limiting, the initial state of the tilting frame 33 is flush with the highest point of the anti-friction wheel 32. When the H-beam 101 slides onto the tilting frame 33, the self-locking of the drive motor 333, the rigid contact between the non-bearing surface of the baffle 3311 and the end of the rotating plate 331 and the L-shaped support leg 3 effectively restrict the tilting frame 33 and stress dispersion. The support frame 332 is concave in shape, and the support frame 332 has an integrally formed rib plate 3321 to improve the structural rigidity of the support frame 332 itself. The tilting frame 33 is installed... The L-shaped support leg 3 has a concave end, and the sixth linear actuator 334 is screwed inside the concave end. The sixth linear actuator 334 lifts the H-shaped steel 101 and flips it through the drive motor 333. The drive motor 333 is preferably a servo motor with electromagnetic braking, which can achieve safe self-locking under power failure or instantaneous heavy load impact. The sixth linear actuator 334 can be an electric actuator, pneumatic actuator, hydraulic actuator, or electro-hydraulic actuator, or a servo electric cylinder. The sixth linear actuator 334 is also set synchronously.

[0057] like Figure 9 As shown, because the L-shaped support leg 3 with the flipping frame 33 is provided at the end for feeding, the top surface friction reduction wheel 32 covers a shorter length than the L-shaped support leg 3 with the receiving component 31. The overall length of each L-shaped support leg 3 is consistent, and the H-beam 101 can slide to the end through the friction reduction wheel 32.

[0058] It should be noted that although the L-shaped support leg 3 in this embodiment has a slope, the connecting plates at its ends that are screwed to the mounting wall are all in a vertical state to ensure a stable connection with the mounting wall. The two electromagnets 313 in the pair have equal power; the distance between the two electromagnets 313 in the pair and the rotation center of the support plate 312 is equal.

[0059] Example 3: A laser cutting method for a transport-type laser cutting machine, such as... Figures 1-21 As shown, it includes the following steps: When transportation is required, the optimal loading method should be selected based on the on-site construction conditions, the accuracy of the lifting equipment, and the manpower configuration. When the accuracy of the lifting equipment at the construction site is low, there are few manpower and no time to correct it, the loading assembly structure of the L-shaped outrigger 3 with slope and the movable grid 424 is preferred. When the construction site has a high precision lifting equipment and a large number of workers, it is preferable to use a loading assembly structure with vertical L-shaped support legs 3 and abutment columns 43.

[0060] After the equipment arrives at the construction site with container 1, the pin at the top of the protective frame 12 is released, the protective frame 12 is unfolded outward, and the L-shaped support legs 3 are installed.

[0061] H-beam 101 was transferred from the H-beam 101 storage area at the construction site using lifting equipment.

[0062] S1. Use lifting equipment to hoist H-beam 101 and place it in the receiving trough; S2, The receiving component 31 drives the H-beam 101 to rotate until it is placed in an I-shape; The third linear actuator 3111 lifts, and the fourth linear actuator 3121 and the fifth linear actuator 3122 push the two support plates 312 to form a "V" shaped receiving groove, placing the H-beam 101 in the receiving groove and magnetically locking the H-beam 101. The fourth linear actuator 3121 and the fifth linear actuator 3122 retract, causing the two support plates 312 to flip outward, forcing the H-beam 101 to be converted into a standard horizontal I-beam upright state.

[0063] In the magnetically locked state, the fourth linear actuator 3121 and the fifth linear actuator 3122 retract in coordination under the command of the control handle, controlling the two support plates 312 to slowly flip outward to a horizontal state. During this process, since one side of the H-beam 101 has been attracted by the electromagnet 313, the H-beam 101 is forced to rotate with its flipping action until all tilt angles are eliminated and it is forcibly converted into a standard horizontal H-beam upright state.

[0064] S3 and H-beam 101 fall onto L-shaped support leg 3 and slide to the opening position on the side of container 1; The third linear actuator 3111 retracts downward to reset, the H-beam 101 in the I-shape state is demagnetized, placed on the top surface of the L-shaped support leg 3, and slides towards the end of the L-shaped support leg 3 via the friction reduction wheel 32 on the top surface of the L-shaped support leg 3 and the slope, until it is received by the flipping frame 33.

[0065] After the workpiece is upright and kept horizontal, the third linear actuator 3111 retracts downward to reset, driving the entire assembly to retract downward.

[0066] During the descent, the bottom of the H-beam 101 contacts the friction-reducing wheel 32 on the top surface of the L-shaped support leg 3, which mechanically resists the residual vertical attraction force of the electromagnet 313, thus achieving physical demagnetization. Finally, the H-beam 101, in a standard I-shape, sits smoothly on the L-shaped support leg 3 and, with its own 4% gentle slope and friction-reducing wheel 32, slides smoothly into the transverse transfer platform 4 inside the container 1.

[0067] S4 and H-beam 101 are rotated to form an H-shape and fastened on the transverse transfer table 4; S41, the transverse transfer platform 4 is moved to the opening position on the side of container 1; S42, the movable gate 424 is close to the sword gate 422 and fits against the side wall; S43, the tilting frame 33 drives the H-beam 101 to rise and then rotates until the H-beam 101 is fastened to the outer periphery of the sword grid 422 and the movable grid 424; S44, the movable grid 424 moves away from the sword grid 422 to the inner wall of the flange plate of the H-beam 101 near the processing unit 2.

[0068] The sixth linear actuator 334 lifts the H-beam 101 in the I-beam shape, and the transverse transfer table 4 slides until it is attached to the end of the L-shaped support leg 3. The drive motor 333 drives the rotating plate 331 to flip.

[0069] H-beam 101 is smoothly transferred to the receiving platform 42, while the second linear actuator 423 pulls the movable grid 424 to smoothly receive and level the H-beam 101.

[0070] When the H-beam 101 in its standard I-beam shape slides to the end of the L-shaped support leg 3, it is supported by the rotating plate 331 with baffle 3311. The operator sends a command via the control handle to activate the sixth linear actuator 334, which lifts upwards, thus smoothly lifting the H-beam 101 off the L-shaped support leg 3. At this time, the movable base 41 moves outwards, closer to the end of the L-shaped support leg 3, to avoid motion interference between the H-beam 101 and the first linear actuator 421. The second linear actuator 423 pushes the movable grid 424 to align with the sword grid 422. In the next step, the first linear actuator 421 pulls the support platform 42 outward to move it closer to the flipping area of ​​the flipping frame 33. The servo motor drives the rotating shaft to rotate, causing the "L"-shaped rotating plate 331 to rotate around the axis on the support frame 332, thereby flipping the "I" shape into a standard "H" shape. This allows the H-beam 101 to cover the movable grid 424 and sword grid 422 on the support platform 42. During the slow flipping process of the H-beam 101, the second linear actuator 423 simultaneously pulls the movable grid 424 to smoothly support and level the H-beam 101, reducing the impact force when the H-beam 101 flips.

[0071] S5, the transverse transfer table 4 moves the H-beam 101 to the position of processing unit 2.

[0072] Workers enter the control area to perform laser cutting on H-beam 101. Controlled by controller 21, the five-axis laser cutting head 23, driven by the moving crossbeam 22 and the vertical transmission mechanism 24, performs high-precision three-dimensional cutting on the H-beam 101 directly below. After the cutting is completed, the transverse transfer table 4 moves to the end for manual unloading.

[0073] It should be noted that the space on the protective frame 12 of the steel structure is large enough for a person to step in and retrieve the parts after they have been cut into smaller components. The control handle is set separately and is controlled by the staff, so that the staff can observe the working status of the receiving component 31 and the flipping frame 33 on the L-shaped support leg 3 when the H-shaped steel 101 is transferred.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
