When the plate-like steel structure or columnar steel structure is on the processing platform, the steel structure is very likely to tilt due to the eccentric force generated during the cutting process. Even if it is clamped by a clamping device, it cannot be applied to steel structures of all shapes. For example, for a columnar steel structure, rolling deflection is very likely to occur, resulting in certain limitations in the cutting of the steel structure. Summary of the invention

At this time, the center line of the columnar steel structure is consistent with the center line of the limiting platform, so that the columnar steel structure can remain stable during cutting, and can limit steel structures of various shapes and sizes, avoiding the problem of limitations when cutting steel structures.

[0018] 2. The present application utilizes an arc-shaped limit ring to control the position of the arc-shaped limit ring by pushing the telescopic rod to start the arc-shaped limit ring, so that the arc-shaped limit ring is close to the shell.

DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0033] See also Figure 1-9 As shown, a fixed-distance laser cutting device suitable for transporting steel structures includes a supporting base plate 3 for limiting the position of the steel structure and a supporting top plate 1 for limiting the position of the cutting mechanism 6. In the present application, a first adjusting mechanism 2 and a second adjusting mechanism 5 for clamping the steel structure are provided on the supporting base plate 3, wherein the distance between the first adjusting mechanism 2 and the second adjusting mechanism 5 is adjustable. When in use, the first adjusting mechanism 2 and the second adjusting mechanism 5 are respectively used to clamp a certain length of the steel structure, and then the cutting mechanism 6 is started to cut the steel structure to obtain a certain length of the steel structure segment, and in the present application, a distance adjusting mechanism 4 for adjusting the distance between the first adjusting mechanism 2 and the second adjusting mechanism 5 is provided between the first adjusting mechanism 2 and the second adjusting mechanism 5, and the length of the steel structure can be adaptively adjusted by adjusting the first adjusting mechanism 2 and the second adjusting mechanism 5.

[0034] As a further embodiment of the present application, the support top plate 1 and the support bottom plate 3 are fixedly connected by connecting columns to achieve the overall stability of the device, and the support bottom plate 3 is installed on a fixed frame to further ensure the stability of the device during cutting operation.

[0035] Furthermore, the distance adjustment mechanism 4 includes an adjusting telescopic rod 41, wherein the adjusting telescopic rod 41 is fixedly mounted on the supporting base plate 3, and a connecting push plate 42 is provided at the output end of the adjusting telescopic rod 41, the connecting push plate 42 is slidably connected to the supporting base plate 3, and an adjusting limit rod 43 is relatively slidably provided on the first adjusting mechanism 2 and the second adjusting mechanism 5. When in use, the connecting push plate 42 is pushed by starting the adjusting telescopic rod 41 to adjust the distance between the connecting push plates 42 respectively arranged on the first adjusting mechanism 2 and the second adjusting mechanism 5, thereby adaptively adjusting the cutting length of the steel structure. In the present application, the use of the adjusting limit rod 43 is used to further realize the stable horizontal adjustment of the distance between the first adjusting mechanism 2 and the second adjusting mechanism 5.

[0036] In order to achieve stable movement of the first adjustment mechanism 2 and the second adjustment mechanism 5, the present application also includes a first sliding base 23 and a second sliding base 25, wherein the first sliding base 23 is fixedly mounted on the supporting bottom plate 3, and the second sliding base 25 is fixedly mounted on the supporting top plate 1, and the first sliding base 23 and the second sliding base 25 are respectively slidably connected to the first adjustment mechanism 2 and the second adjustment mechanism 5, that is, used to achieve stable adjustment of the distance between the first adjustment mechanism 2 and the second adjustment mechanism 5.

[0037] The first adjustment mechanism 2 and the second adjustment mechanism 5 have the same structure. Taking the first adjustment mechanism 2 as an example, the first adjustment mechanism 2 includes a first support rod 21 and a second support rod 22, wherein the first support rod 21 and the second support rod 22 are fixedly connected by a vertical rod, and the vertical rod is slidably connected to the first sliding base 23 and the second sliding base 25 respectively, so as to realize stable adjustment of the positions of the first support rod 21 and the second support rod 22. An adjustment box 24 for performing fixed distance processing on the steel structure is arranged on the side of the first support rod 21 and the second support rod 22.

[0038] In the above technical solution, the adjustment box 24 is used to realize the clamping and positioning function of the steel structure, and then the adjustment telescopic rod 41 is started to control the distance between the first adjustment mechanism 2 and the second adjustment mechanism 5, so that the adjacent first support rods 21 and the adjacent second support rods 22 slide relative to each other, and the adjustment limit rod 43 is slidably connected to one group of the first support rods 21 or the second support rods 22 to ensure the relative level of the first support rods 21 and the second support rods 22. Further, when the cutting mechanism 6 is started, the steel structure is directly cut off to obtain three groups of steel structures with relatively stable dimensions. That is, two groups of steel structure segments are formed under the action of two adjustment boxes 24, and the distance between two adjacent adjustment boxes 24 is used to form a third group of steel structure segments. Therefore, in the present application, three groups of steel structure segments can be formed at the same time to ensure the efficiency of steel structure cutting. At the same time, since the distance between the first adjustment mechanism 2 and the second adjustment mechanism 5 is adjustable, two sections of steel structure with the same size and one section of steel structure with different sizes can also be produced at the same time to achieve two groups of steel structures with different sizes, which is convenient for positioning and cutting the steel structure as needed, so as to facilitate the packaging and transportation of the steel structure. And the two ends of the same group of steel structures are cut simultaneously, so that the gravity and the force applied by the cutting at the two ends of the steel structure are of the same direction and magnitude, so as to ensure the stability of the steel structure during cutting and avoid the problem of large errors caused by the deflection of the steel structure during the cutting process.

[0039] An arc plate 8 is fixed on the supporting base plate 3. The arc plate 8 is arc-shaped, and a material discharge trough 7 is symmetrically opened on the supporting base plate 3. During cutting, the steel structure between the first adjusting mechanism 2 and the second adjusting mechanism 5 falls after being cut and directly falls on the arc plate 8. The guiding function of the arc plate 8 is utilized to make the steel structure fall on the position of the material discharge trough 7, so that the material discharge problem of the generated steel structure can be realized by utilizing the material discharge trough 7. Since the first adjusting mechanism 2 and the second adjusting mechanism 5 have extended lengths at both ends, the material discharge function can be automatically realized by a manipulator.

[0040] As a further embodiment of the present application, the cutting mechanism 6 includes a sliding top plate 64, on the side of which a limiting slider 65 is fixed, wherein the limiting slider 65 is slidably connected to the second sliding base 25, and the sliding top plate 64 is fixedly connected to the vertical rod. When the first adjustment mechanism 2 or the second adjustment mechanism 5 moves toward or away from each other, the sliding top plate 64 will be driven to move adaptively toward or away from each other, thereby controlling the position of the cutting assembly installed on the sliding top plate 64, so that the position of the cutting assembly and the adjustment box 24 are coordinated, thereby facilitating the use of the position of the adjustment box 24 to achieve cutting of the steel structure.

[0041] The cutting assembly includes a height-adjustable telescopic rod 63, wherein the height-adjustable telescopic rod 63 is installed on the sliding top plate 64 by bolts, so the position of the height-adjustable telescopic rod 63 can be replaced by the installation position of the bolts, so in the present application, the position of the height-adjustable telescopic rod 63 can be matched and installed according to the position of the adjustment box 24, and the output end of the height-adjustable telescopic rod 63 is provided with a laser cutter 66 for cutting the steel structure, that is, when in use, the height of the laser cutter 66 is controlled by the height-adjustable telescopic rod 63, so that the steel structure is directly cut by the laser cutter 66, and in the present application, the laser cutter 66 is rotatable for adjusting the action angle of the laser cutter 66, thereby realizing direct cutting of the steel structure, so in the present application, a laser base is provided at the end of the height-adjustable telescopic rod 63, and a laser motor for adjusting the angle of the laser cutter 66 is provided on the laser base, thereby realizing adjustment of the cutting direction of the laser cutter 66.

[0042] The adjusting box body 24 includes a pushing telescopic rod 243, wherein the pushing telescopic rod 243 is fixed on the vertical rod, and a limiting push plate 244 is fixed at the output end of the pushing telescopic rod 243, wherein the limiting push plate 244 is slidably connected with the connecting push plate 42, and the connecting push plate 42 is fixedly installed on the adjacent first support rod 21 and the adjacent second support rod 22 to realize the sliding limit of the limiting push plate 244, and arc-shaped limiting rings 242 are fixedly installed at both ends of the limiting push plate 244, respectively. The arc-shaped limiting rings 242 are used to realize the preliminary limiting function of the columnar steel structure, and the arc-shaped limiting rings 242 are installed at both ends of the shell 241, so the shell 241 is fixedly installed on the connecting push plate 42. When in use, the position of the limiting push plate 244 is controlled by pushing the telescopic rod 243 to start, so that the arc-shaped limiting ring 242 moves to the input end and the output end of the shell 241, and the arc-shaped limiting ring 242 is used to realize the limiting function of the steel structure.

[0043] As a further embodiment of the present application, since the size of the arc-shaped limit ring 242 is certain and can only be used for steel structures of fixed sizes, the present application also provides an adjustable limit mechanism inside the shell 241 to limit the position of the steel structure.

[0044] In the present application, the adjustable limit mechanism includes a first limit platform 247 and a second limit platform 248. The first limit platform 247 is symmetrically fixedly installed inside the shell 241, and the first limit platform 247 is in an inverted L shape. The second limit platform 248 is fixed on the first limit platform 247, wherein the second limit platform 248 is in an inverted L shape. When in use, the first limit platform 247 is used to place the frame-shaped steel structure at a distance from the lowest end, and the first limit platform 247 and the second limit platform are used to adjust the limit mechanism. The side 248 forms a placement limit for the frame-type steel structure of the second size, and the upper part of the second limiting platform 248 and the side limiting plate 249 are used to realize the placement limit of the frame-type steel structure of the third size. Therefore, in the present application, the frame-type groove 246, the first limiting platform 247, the second limiting platform 248 and the side limiting plate 249 are used to realize the placement limit of frame-type steel structures of different sizes, so that the frame-type steel structure can pass through the first adjusting mechanism 2 and the second adjusting mechanism 5 relatively straight to ensure the stability of its cutting.

[0045] In the present application, a side mounting base 2412 is fixed to the side of the side limit plate 249, and a mounting screw hole 2413 is opened on the side of the second limit platform 248. By connecting the side mounting base 2412 and the mounting screw hole 2413 with bolts, the position of the side limit plate 249 can be adjusted to limit frame-type steel structures of different sizes.

[0046] Furthermore, a top telescopic rod 2411 is fixed on the top of the shell 241, a movable plate 2410 is fixed on the output end of the top telescopic rod 2411, and a limiting pressure plate 245 for clamping and fixing the steel structure is fixed on the end of the movable plate 2410 away from the top telescopic rod 2411. When in use, the top telescopic rod 2411 is started to control the movable plate 2410 to move longitudinally, so that the limiting pressure plate 245 is tightly pressed on the steel structure to realize the limiting function of the steel structure.

[0047] In the present application, in addition to being able to clamp and fix the frame-type steel structure, the present application can also limit the columnar steel structure, that is, when the columnar steel structure is within a certain range, it is clamped on the arc angle of the first limiting platform 247 to achieve the limitation of the columnar steel structure of the first step size. When the size of the columnar steel structure is large enough to be clamped on the arc angle of the second limiting platform 248, the second size columnar steel structure can be limited. Under the action of gravity, the center of the columnar steel structure can be on the center line of the shell 241. Then, by starting the top telescopic rod 2411, the limiting pressure plate 245 is pressed down on the columnar steel structure to limit the position of the columnar steel structure.

[0048] As another embodiment of the present application, the laser cutter 66 in the application is replaced by a power box 61. The output end of the power box 61 is provided with a rotating cutter 62 for directly cutting the steel structure. When in use, the rotating cutter 62 is driven by the power box 61 to achieve the cutting function of the steel structure.

[0049] When the present invention is in use, firstly, according to the shape and size of the steel structure, it is determined whether it can be limited and fixed by the arc-shaped limit ring 242. If so, the arc-shaped limit ring 242 is moved to the shell 241 by pushing the telescopic rod 243, and then the columnar steel structure passes through the two arc-shaped limit rings 242 to limit the position of the columnar steel structure. If the arc-shaped limit ring 242 cannot be used for limiting and fixing, the arc-shaped limit ring 242 is removed from the shell 241 by pushing the telescopic rod 243, and then the shape of the steel structure is used to limit it inside the shell 241, that is, the shell 241 can limit the position of steel structures of various sizes and shapes, and then the top telescopic rod 2411 is started to press the movable plate 2410 downward, and the limit pressing plate 245 is pressed on the steel structure to further limit the steel structure.

[0050] Subsequently, the connecting push plate 42 is pushed by adjusting the start of the telescopic rod 41, so as to adjust the distance between the connecting push plates 42 respectively arranged on the first adjusting mechanism 2 and the second adjusting mechanism 5, so as to adaptively adjust the cutting length of the steel structure. When the cutting mechanism 6 is started, the steel structure is directly cut off to obtain three groups of steel structures with relatively stable sizes, that is, two groups of steel structure segments are formed under the action of the two adjusting boxes 24, and the third group of steel structure segments is formed by using the distance between the two adjacent adjusting boxes 24. Therefore, in the present application, three groups of steel structure segments can be formed at the same time to ensure the efficiency of steel structure cutting. At the same time, since the distance between the first adjusting mechanism 2 and the second adjusting mechanism 5 is adjustable, two sections of steel structures with the same size and one section of steel structures with different sizes can also be produced at the same time, so as to obtain two groups of steel structures with different sizes, which is convenient for positioning and cutting the steel structure according to needs, so as to facilitate the packaging and transportation of the steel structure.

[0051] When the cutting mechanism 6 is started, a laser base is provided at the end of the height-adjusting telescopic rod 63, and a laser motor for adjusting the angle of the laser cutter 66 is provided on the laser base, thereby adjusting the cutting direction of the laser cutter 66 and cutting the steel structure.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
