[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] The steel structure cutting equipment according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, the steel structure cutting equipment of the embodiment of the present application may include a cutting table 1, a cutting machine 2, a feeding assembly 3, a positioning assembly 4, two sliding limit assemblies 5 and two cutting limit assemblies 6.

[0024] Among them, a limit groove 10 and a feeding hole 11 are opened on the cutting table 1, and a plurality of rollers 12, scale lines 13 and two slide rails 14 are arranged on the cutting table 1. The plurality of rollers 12 are rotatably arranged on the cutting table 1 and are located in the limit groove 10. The two slide rails 14 are respectively arranged on the cutting table 1 and are located in the limit groove 10.

[0025] It can be understood that the provision of multiple rollers 12 can make the movement of the steel structure on the cutting table 1 more convenient. In addition, the provision of the limiting grooves 10 can limit the steel structure, thereby preventing the steel structure from shaking when moving to the cutting position.

[0026] It can be understood that, by setting the scale line 13, it is convenient for relevant operators to control the moving distance of the steel structure.

[0027] A first baffle 15 and a second baffle 16 are arranged in the cutting table 1 . The first baffle 15 and the second baffle 16 enclose and form a sliding chamber 17 . The cutting machine 2 is arranged at one side of the cutting table 1 .

[0028] It should be noted that the cutting machine 2 described in this embodiment is a common cutting device in the field of steel structure cutting and will not be described in detail here.

[0029] The feeding assembly 3 may include a motor 30 , a cam block 31 , a moving assembly 32 and a limiting assembly 33 .

[0030] The motor 30 is disposed on the second baffle 16 , the cam block 31 is disposed in the moving assembly 32 and is rotatably abutted against the moving assembly 32 , and the cam block 31 is used to control the moving assembly 32 to rotate and push.

[0031] It should be noted that one end of the cam block 31 described in this embodiment is protruding, so as to facilitate the rotation and pushing of the moving component 32.

[0032] It should be noted that the motor 30 described in this embodiment is connected to an encoder, and the encoder is used to control the rotation position of the output shaft of the motor 30 , that is, to control the rotation position of the cam block 31 .

[0033] The moving component 32 is slidably disposed in the sliding chamber 17 , one end of the moving component 32 passes through the feeding hole 11 and extends into the limiting groove 10 , and the moving component 32 is used for adsorption and pushing control of the steel structure.

[0034] It can be understood that the rotation of the cam block 31 drives the rotation of the moving component 32, so that one end of the moving component 32 adsorbs the column steel structure and drives the steel structure to move during the lateral movement, thereby realizing the movement of the steel structure without the need for relevant operators to manually push the steel structure, thereby reducing the work intensity of relevant operators.

[0035] The limit assembly 33 is in sliding contact with the moving assembly 32, and the limit assembly 33 is used to limit the moving position of the moving assembly 32. The positioning assembly 4 may include a positioning frame 40 and a sliding frame 41. The positioning frame 40 is set on the steel structure, and the sliding frame 41 is slidably set on the cutting table 1 and is located on the scale line 13, and an infrared proximity sensor 410 is set on the sliding frame 41.

[0036] It should be noted that the infrared proximity sensor 410 described in this embodiment is a common distance sensor on the market. When the infrared light emitted by it encounters an object, it will be reflected back by the object, and after receiving the reflected infrared light, the sensor will generate a corresponding electrical signal. According to the received signal strength, the sensor can determine the distance and existence of the object. When the object approaches a certain distance, the sensor will trigger a stop signal, that is, when the sliding frame 41 moves to the top of the infrared proximity sensor 410, the stop signal will be transmitted to the controller (not shown in the figure), and the controller will control the moving component 32 to stop moving, so that the cutting machine 2 can cut the steel structure that has been moved to the specified position.

[0037] The two sliding limit assemblies 5 are respectively slidably connected to the corresponding slide rails 14 . The two cutting limit assemblies 6 are respectively arranged on the cutting table 1 , located in the limit groove 10 , and located at one side of the cutting machine 2 .

[0038] It can be understood that by setting up two sliding limit assemblies 5, the two sides of the steel structure can be clamped and limited, and by setting up the slide rails 14, the steel structure can be moved while clamping, thereby eliminating the need for multiple manual limit and fixation of the steel structure.

[0039] It can be understood that, by setting the cutting limit assembly 6, the steel structure can be fixed when the cutting machine 2 cuts the steel structure, thereby improving the cutting quality of the steel structure.

[0040] Specifically, during the actual operation, the relevant staff places the steel structure in the limit groove 10 of the cutting table 1 and places it above the roller 12. The controller controls the two sliding limit assemblies 5 to extend an equal distance to limit and clamp the steel structure. The relevant operator adsorbs the positioning frame 40 on the steel structure and aligns it with the 0 scale line 13 of the steel structure, and operates the sliding frame 41 to move on the scale line 13, and moves the distance required for a single cutting of the steel structure.

[0041] The controller controls the motor 30 to rotate and drives the cam block 31 to rotate. The rotation of the cam block 31 drives the moving component 32 to move. The moving component 32 drives the steel structure to move toward the cutting machine 2. In the process of driving the steel structure to move, the positioning frame 40 gradually moves toward the sliding frame 41. When it moves to the top of the sliding frame 41, the infrared proximity sensor 410 detects the positioning frame 40 and transmits a stop signal to the controller. The controller controls the motor 30 to stop rotating, and then controls the two cutting limit components 6 to clamp the steel structure, so as to cut the steel structure again, so as to ensure the cutting quality of the steel structure. After the cutting is completed, the two cutting limit components 6 release the clamping limit on the steel structure, and when the next size of the steel structure is cut, the above operation is repeated to complete the entire cutting of the steel structure.

[0042] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 5 As shown, the moving assembly 32 may include a rotating frame 320 , a connecting rod 321 and a magnetic block 322 .

[0043] Among them, the rotating frame 320 is slidably set in the sliding chamber 17, one end of the connecting rod 321 is set on the rotating frame 320, the other end of the connecting rod 321 passes through the feeding hole 11 and extends into the limiting groove 10, and the magnetic block 322 is set at the other end of the connecting rod 321.

[0044] It can be understood that, by disposing the rotating frame 320 in the sliding chamber 17 , the rotating frame 320 can be limited, and by disposing the magnetic block 322 , the steel structure can be adsorbed and driven to move.

[0045] In one embodiment of the present application, Figure 1 and Figure 5 As shown, the limiting assembly 33 may include a first limiting frame 330 , two sliding rods 331 and two second limiting frames 332 .

[0046] Among them, the first limit frame 330 is slidably connected to the connecting rod 321, the two sliding rods 331 are fixedly arranged on both sides of the first limit frame 330, the two second limit frames 332 are respectively arranged on the second baffle 16, and the two second limit frames 332 are slidably connected to the corresponding sliding rods 331.

[0047] It can be understood that, through the limitation of the connecting rod 321 by the first limit frame 330 and the limitation of the sliding rod 331 by the two limit frames, the circularly rotating cam block 31 drives the rotating frame 320 and the magnetic block 322 to rotate in a rectangular shape, thereby facilitating the continuous pushing of the steel structure, that is, when the protruding part of the cam block 31 abuts against the top of the rotating frame 320, it drives the connecting rod 321 and the magnetic block 322 to move upward and adsorb the steel structure.

[0048] When the cam block 31 continues to rotate, it will abut against the side of the rotating frame 320, thereby driving the connecting rod 321 and the magnetic block 322 to move toward that side, and driving the steel structure to move toward the direction of the cutting machine 2. When the cam block 31 continues to rotate, it will abut against the bottom of the rotating frame 320, thereby driving the connecting rod 321 and the magnetic block 322 to move downward, so that the magnetic block 322 is separated from the adsorption of the steel structure.

[0049] The cam block 31 continues to rotate and abuts against the other side of the rotating frame 320, thereby driving the connecting rod 321 and the magnetic block 322 to move toward that side. At this time, the magnetic block 322 is separated from the steel structure and will not drive the steel structure to move. When the cam block 31 continues to rotate, it abuts against the top of the rotating frame 320, and repeats the above operation to complete the continuous pushing of the steel structure by the moving component 32.

[0050] In one embodiment of the present application, Figure 1 As shown, the sliding limiting assembly 5 may include a supporting plate 50 , a first electric telescopic rod 51 and a pressing plate 52 .

[0051] The support plate 50 is slidably connected to the slide rail 14 , one end of the first electric telescopic rod 51 is connected to the support plate 50 , and the other end of the first electric telescopic rod 51 is connected to the abutting plate 52 .

[0052] It should be noted that the abutment plate described in this embodiment is provided with anti-slip grooves, so as to improve the abutment effect of the abutment plate 52 .

[0053] In one embodiment of the present application, Figure 1 As shown, the cutting limiting assembly 6 may include a mounting plate 60 , a second electric telescopic rod 61 and a limiting plate 62 .

[0054] The mounting plate 60 is disposed on the cutting table 1 and is located in the limiting groove 10 . One end of the second electric telescopic rod 61 is connected to the mounting plate 60 , and the other end of the second electric telescopic rod 61 is connected to the limiting plate 62 .

[0055] It should be noted that the limiting plate 62 described in this embodiment is provided with anti-slip grooves, so as to improve the anti-slip effect of the limiting plate 62 .

[0056] It should be noted that when the cam block 31 of the cutting limit assembly 6 described in this embodiment abuts against the bottom of the rotating frame 320, the encoder transmits a signal to the controller, and the controller controls the cutting limit assembly 6 to clamp and limit the steel structure, thereby preventing the magnetic block 322 from magnetically disengaging from the steel structure and dragging the movement of the steel structure, thereby ensuring the cutting quality of the steel structure. In addition, when the cam block 31 rotates from the bottom of the rotation to the side of the rotating frame 320 to abut, the cutting limit assembly 6 releases the limit clamping of the steel structure, thereby ensuring the magnetic block 322 has a pushing effect on the steel structure again.

[0057] Specifically, during the actual operation, the relevant staff places the steel structure in the limit groove 10 of the cutting table 1 and places it above the roller 12. The controller controls the first electric telescopic rod 51 in the two sliding limit assemblies 5 to extend an equidistant distance to limit and clamp the steel structure. The relevant operator adsorbs the positioning frame 40 on the steel structure and aligns it with the 0 scale line 13 of the steel structure, and operates the sliding frame 41 to move on the scale line 13, and moves the distance required for a single cutting of the steel structure.

[0058] The controller controls the motor 30 to rotate, and drives the cam block 31 to rotate. The rotation of the cam block 31 drives the rotating frame 320 and the magnetic block 322 to rotate in a rectangular shape, thereby facilitating the continuous pushing of the steel structure (that is, when the protruding part of the cam block 31 abuts against the top of the rotating frame 320, the connecting rod 321 is driven to slide upward in the first limit frame 330, and the magnetic block 322 is driven to move upward and adsorb the steel structure.

[0059] When the cam block 31 continues to rotate, it will abut against the side of the rotating frame 320, thereby driving the connecting rod 321 to abut against the first limit frame 330, so that the sliding rod 331 moves in the second limit frame 332 toward the cutting machine 2, and drives the magnetic block 322 to move toward this side, and drives the steel structure to move in the direction of the cutting machine 2. When the cam block 31 continues to rotate, it will abut against the bottom of the rotating frame 320, thereby driving the connecting rod 321 to slide downward in the first limit frame 330, and driving the magnetic block 322 to move downward, so that the magnetic block 322 is separated from the adsorption of the steel structure.

[0060] The cam block 31 continues to rotate and will abut against the other side of the rotating frame 320, thereby driving the connecting rod 321 to abut against the first limit frame 330, causing the sliding rod 331 to move in the second limit frame 332 in a direction away from the cutting machine 2, and driving the magnetic block 322 to move to that side. At this time, the magnetic block 322 is detached from the steel structure and will not drive the steel structure to move.

[0061] When the cam block 31 continues to rotate, it abuts against the top of the rotating frame 320, and repeats the above operation to complete the continuous pushing of the steel structure by the moving component 32), and the moving component 32 moves. The moving component 32 drives and controls the steel structure to move toward the cutting machine 2, and in the process of driving the steel structure to move, the positioning frame 40 gradually moves toward the sliding frame 41. When it moves to the top of the sliding frame 41, the infrared proximity sensor 410 detects the positioning frame 40 and transmits a stop signal to the controller. The controller controls the motor 30 to stop rotating, and then controls the two cutting limit components 6 to clamp the steel structure, so that the steel structure is cut again, thereby ensuring the cutting quality of the steel structure.

[0062] After the cutting is completed, the two cutting limit assemblies 6 release the clamping limit on the steel structure, and when cutting the steel structure of the next size, the above operation is repeated to complete the entire cutting of the steel structure.

[0063] In summary, the steel structure cutting equipment of the embodiment of the present application does not need to adjust the steel structure body when adjusting the cutting position, and when a single steel structure is cut multiple times, there is no need to manually limit and fix the steel structure multiple times, thereby improving the cutting efficiency of the steel structure.
