Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1 As shown, combined with Figure 2-6 This utility model discloses a steel structure cutting device for building construction, including a conveyor frame 1, a conveying device 11 inside the conveyor frame 1, and a cutting device 12 in the middle of one side of the conveyor frame 1; the conveying wheel on the conveying device 11 is provided with an I-beam 13; a fixing component 2 is provided in the middle of the lower end face of the conveyor frame 1; and a setting length component 3 is provided on one side of the conveyor frame 1.

[0028] In this embodiment, the fixing component 2 includes a hydraulic cylinder 21, which is fixedly connected to the middle of one side of the conveyor frame 1 via a first fixing plate. The output end of the hydraulic cylinder 21 is connected to a moving rod 22, one end of which is fixedly connected to a push plate 23. A first pressure plate 24, a second pressure plate 241, and a third pressure plate 242 are evenly arranged along the length direction on the upper surface of the push plate 23. Activating the hydraulic cylinder 21 drives the moving rod 22 to move to one side. The moving rod 22 is pulled by the push plate 23 to move to one side, causing one side of the first pressure plate 24, the second pressure plate 241, and the third pressure plate 242 to abut against one side of the I-beam 13. This causes the I-beam 13 to gradually press against one side of the second abutment block 27 and the second guide block 28. The fixing surfaces of the second abutment block 27 and the second guide block 28 are used to press against the I-beam 13, effectively ensuring stable cutting by the cutting wheel and preventing deviation.

[0029] In this embodiment, the first pressure plate 24 and the second pressure plate 241 are embedded inside the first slot 251 and the second slot 252 on one side of the first abutment block 25, and the third pressure plate 242 is embedded in the third slot 261 on one side of the first guide block 26. The lower end face of the first abutment block 25 is fixed to one side of the upper end face of the conveyor frame 1, and the lower end face of the first guide block 26 is fixed to the other side of the lower end face of the conveyor frame 1. A second abutment block 27 and a second guide block 28 are provided on both sides of the upper end face of the conveyor frame 1. When the fixing assembly 2 is not activated, the first pressure plate 24, the second pressure plate 241, and the third pressure plate 242 are all embedded inside the first slot 251, the second slot 252, and the third slot 261, respectively, to avoid force obstruction during the conveying of the I-beam 13.

[0030] In this embodiment, one side of the second abutment block 27 and the second guide block 28 presses against one side of the I-beam 13. One side of the first pressure plate 24, the second pressure plate 241, and the third pressure plate 242 all press against one side of the I-beam 13. One side of the first abutment block 25 is opposite to one side of the second abutment block 27, and one side of the first guide block 26 is opposite to one side of the second guide block 28. The material is smoothly conveyed to the cutting point by the guidance of the first guide block 26 and the second guide block 28.

[0031] In this embodiment, the set length component 3 includes a support frame 31 fixedly connected to one side of the conveyor frame 1. The upper surface of the support frame 31 has grooves 311 on both sides. A sliding block 32 is slidably connected inside the groove 311. The lower surface of the sliding block 32 is fixedly connected to a first motor 33 through a second fixing block. The output end of the first motor 33 is connected to a first rotating shaft 34. One end of the first rotating shaft 34 is connected to a first gear 35. The first gear 35 meshes with a first rack 36. A support plate 37 is fixedly connected to one side of the first rack 36. One side of the support plate 37 is fixed to the upper part of the inner side of the support frame 31. The first motor 33 is started to drive the first rotating shaft 34 to rotate clockwise. The first gear 35 is subjected to force and meshes clockwise with the first rack 35, causing the sliding block 32 to slide to one side inside the slide groove 311 until the sliding block 32 slides to the predetermined length. The first motor 33 can then be stopped. This allows for the setting of dimensions for I-beams 13 of different lengths and widths, eliminating the need for cutting by marking and eliminating the need for workers to measure and adjust back and forth. This effectively speeds up the work process and improves practicality.

[0032] In this embodiment, a second motor 321 is fixedly connected to one side of the lower end face of the sliding block 32. The output end of the second motor 321 is connected to a second rotating shaft 322. A second gear 323 is sleeved on the lower end of the second rotating shaft 322. The second gear 323 meshes with a first blocking component 38 and a second blocking component 39. The first blocking component 38 includes a second rack 381, which meshes with the second gear 323. A sliding elongated shell 382 is slidably fitted to one side of the second rack 381. Fixed rods 383 are fixedly connected to both sides of the upper end face of the sliding elongated shell 382. The upper end face of the fixed rods 383 is fixed to the lower end face of the sliding block 32. A stop rod 384 is fixedly connected to one side of the second rack 381. The first blocking component 38 and the second blocking component 39 have the same structure. The second motor 321 is started to drive the second rotating shaft 322 to rotate counterclockwise. The second gear 323 is subjected to force and meshes counterclockwise with the two second racks 381, causing the two second racks 381 to move in opposite directions. The second racks 381 slide to one side inside the sliding elongated shell 382, ​​and at the same time, they also drive the abutment rod 384 to move to one side. The distance that the two abutment rods 384 move does not exceed the width of the I-beam 13, so as to ensure that the length of the I-beam 13 is accurate.

[0033] In this embodiment, the lower outer side of the abutment 384 abuts against one side of the I-beam 13, ensuring that the cut dimensions of the I-beam 13 are accurate.

[0034] The working principle of this utility model is as follows:

[0035] In this invention, firstly, the length of the I-beam 13 to be cut is adjusted, and the first motor 33 is started to drive the first rotating shaft 34 to rotate clockwise. The first gear 35 is subjected to force and meshes clockwise with the first rack 35, causing the sliding block 32 to slide to one side inside the slide groove 311 until the sliding block 32 slides to the predetermined length. Then the first motor 33 is stopped. Figure 1 As shown, adjust the movement of the two abutment rods 384 according to the width of the I-beam 13. Start the second motor 321 to drive the second rotating shaft 322 to rotate counterclockwise. The second gear 323 is forcefully engaged counterclockwise with the two second racks 381, causing the two second racks 381 to move in opposite directions. The second racks 381 slide to one side inside the sliding elongated shell 382, ​​and at the same time, they also drive the abutment rods 384 to move to one side. The distance that the two abutment rods 384 move does not exceed the width of the I-beam 13. Stop the second motor 321. Figure 5 As shown, the conveying wheel on the conveying device 11 is then activated to convey the I-beam 13. As the I-beam 13 moves towards the cutting device 12, it is smoothly conveyed to the cutting point by the guidance of the first guide block 26 and the second guide block 28. The conveying continues until one side of the I-beam 13 touches the outside of the abutment rod 384, at which point the conveying device is stopped. If the I-beam 13 deviates just before touching the abutment rod 384, the hydraulic cylinder 21 can be activated to drive the moving rod 22 to one side. The moving rod 22 is pulled to one side by the push plate 23, causing one side of the first pressure plate 24, the second pressure plate 241, and the third pressure plate 242 to all touch the deviated side of the I-beam 13, gradually pressing the I-beam 13 against the side of the second abutment block 27 and the second guide block 28. Using the fixed surfaces of the second abutment block 27 and the second guide block 28, the I-beam 13 is adjusted to a straight state. Figure 3 As shown, at this time, the hydraulic cylinder 21 is retracted to its original position.

[0036] After the I-beam 13 contacts the abutment rod 384, the hydraulic cylinder 21 is activated again, causing the first pressure plate 24, the second pressure plate 241, and the third pressure plate 242 to press against the I-beam 13. The I-beam 13 is pressed tightly against the fixed surfaces of the second abutment block 27 and the second guide block 28. At this time, the conveying device is stopped, and the cutting device is activated, allowing the cutting wheel to cut the I-beam 13. After the I-beam 13 is cut, it returns to its original position using the hydraulic cylinder. The conveying device 1 is then activated again to continue conveying the I-beam to one side. The cut section of the I-beam 13 can be conveyed outward by manual labor or by the pressure of the conveying I-beam 13. Before this, the second motor 381 is activated to move the two abutment rods 384 outward, ensuring that the cut section of the I-beam 13 can pass smoothly. After the I-beam 13 passes, the second motor 381 is activated again to drive the two abutment rods 384 to work, thus repeating the process in sequence.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
