[0062] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by identical or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0063] refer to Figures 1 to 7 The present application provides a steel pipe cutting device for construction (hereinafter referred to as the cutting device), comprising: a support 1; a measuring component 2, which is arranged on the support 1, and the measuring component 2 can slide to set the length of the steel pipe 9 to be cut; a fixing component 3, which is arranged on the support 1, and the fixing component 3 can be used to fix the steel pipe 9 to be cut; a cutting component 4, which is arranged on the support 1, and can be used to cut the steel pipe 9 to be cut; a transport component 5, which is arranged on one side of the measuring component 2, and can be used to transport the cut steel pipe 9; a storage component 6, which is connected to the support 1, and can be used to store the cut steel pipe 9 transported by the transport component 5.

[0064] In this embodiment, a plurality of supporting legs 11 are provided below the support 1 to provide support and meet the operating height requirements of the operator.

[0065] In this embodiment, the measuring component 2 includes: a first box body 21, on which a slide groove is provided; a sizing rod 22, which passes through the first end of the first box body 21 and is slidably connected to the first box body 21, and a linear bearing is provided on the first box body 21, which can make the sliding of the sizing rod 22 easier; the first end of the sizing rod 22 is provided with a limit block 221, and the second end of the sizing rod 22 is rotatably connected to a rotating disk 25; a first spring 23, the first end of which is connected to the first end in the slide groove; a slider 24, which is slidably connected in the slide groove, the slider 24 is connected to the second end of the first spring 23, the slider 24 can be slidably mounted on the sizing rod 22, and the slider 24 can be fixed to the sizing rod 22 by a bolt.

[0066] In this embodiment, the method of using the measuring assembly 2 is to first set the length of the steel pipe 9 to be cut, specifically, slide the slider 24 to the length of the size rod 22 to be cut, and then fix the slider 24 and the size rod 22 relative to each other through the bolts on the slider 24. It should be understood that if Figure 1 As shown, the scale aligned on the right side of the slider 24 on the size rod 22 is the set length of the size.

[0067] In this embodiment, the length of the steel pipe 9 to be cut is determined by the scale on the size rod 22. When cutting the steel pipe 9, the steel pipe 9 needs to be placed on the first box 21. Figure 1 and Figure 2 The right side of the steel pipe 9 touches the groove opened on the rotating disk 25. The groove can limit the position of the steel pipe 9. When calculating the length of the cut steel pipe 9, the depth of the groove needs to be calculated into the length of the cut steel pipe 9. Therefore, the length of the cut steel pipe 9 calculated on the size rod 22 is based on Figure 1 The right side of the groove in the first box body 21 is the starting point, and the scale on the size rod 22 that passes through the right end surface of the first box body 21 is the end point. The scale value of the end point minus the scale value of the starting point is the length of the cut steel pipe 9. Therefore, by keeping the depth of the groove consistent with the wall thickness of the right end surface of the first box body 21, the Figure 1 The scale on the left side of the middle size rod 22 connected to the rotating disk 25 is the starting point, and the scale on the size rod 22 aligned with the right side of the slider 24 is the end point.

[0068] In this embodiment, a limiting cylinder 27 is fixedly connected to the rotating disk 25, and both ends of the limiting cylinder 27 are provided with through holes; the first end of the limiting cylinder 27 (i.e., the Figure 2 and Figure 5 The left side of the middle limiting cylinder 27) is rotatably connected to the second end of the sizing rod 22 through a rotating body 222, and the rotating body 222 is fixedly connected to the second end of the sizing rod 22; a rubber pad 223 is provided in the limiting cylinder 27 on the right end surface of the rotating body 222, and the rubber pad 223 is fixedly connected to a fixed block 224, and the fixed block 224 is connected to the first threaded rod 26, and the first threaded rod 26 passes through the limiting cylinder 27 and the rotating disk 25, and is threadedly connected to the second end of the limiting cylinder 27 or the rotating disk 25.

[0069] The rotating body 222 is fixedly connected to the sizing rod 22, and the rotating body 222 and the rotating disk 25 can rotate relative to each other. The rubber pad 223 provides friction to prevent the relative rotation between the rotating body 222 and the rotating disk 25 from rotating too quickly. The friction value can be adjusted by the first threaded rod 26. By rotating the first threaded rod 26 to achieve horizontal displacement of the first threaded rod 26, the rubber pad 223 is pressed against or away from the right end surface of the rotating body 222, thereby adjusting the friction value.

[0070] In this embodiment, the cutting device further comprises a second box body 8, which is provided on the support 1 and connected to the first end of the first box body 21 (i.e. Figure 1 and Figure 2 The second box body 8 is provided with a rotating disk 25 and the transport component 5, and the lower side of the second box body 8 is provided with an opening connected to the storage component 6; the cut steel pipe 9 is transported to the opening of the second box body 8 connected to the storage component 6 by the transport component 5, and then the steel pipe 9 is dropped from the opening into the storage component 6.

[0071] refer to Figures 1 to 4 The transport component 5 includes: a sleeve 55, which is rotatably connected to the rod body of the sizing rod 22 extending out of the first box body 21, and a connecting rod 54 and a counterweight block 56 are connected on the outer wall surface of the sleeve 55 in opposite directions; an arc-shaped hook 53, which is connected to the connecting rod 54, and one side of the opening of the arc-shaped hook 53 is fitted on the inner wall surface of the second box body 8; a limiting slider 51, which is connected to the connecting rod 54, and the limiting slider 51 is slidably clamped on the end face of the first end of the first box body 21; wherein, the limiting slider 51 is slidable along the circumferential direction of the end face of the first box body 21.

[0072] It should be understood that the arc-shaped hook 53 is used to clamp the cut steel pipe 9, refer to Figure 2 When placing the steel pipe 9, the steel pipe 9 passes through the arc-shaped hook 53 and is clamped in the groove in the rotating disk 25. When the steel pipe 9 is cut, the arc-shaped hook 53 on the rotating disk 25 and the transport component 5 respectively sleeves the two ends of the cut steel pipe 9. Due to the weight of the steel pipe 9 itself, the balance between the arc-shaped hook 53 and the counterweight block 56 will be destroyed, causing the sleeve 55 to rotate along the size rod 22. Under the action of gravity, the steel pipe 9 moves downward until it reaches the opening connected between the second box body 8 and the storage component 6. Under the action of gravity, the steel pipe 9 will slide from the opening set in the second box body 8 to the storage component 6, thereby realizing the transportation of the cut steel pipe 9.

[0073] In this embodiment, a stopper 57 is provided above the transport component 5 inside the second box body 8. The function of the stopper 57 is to block the arc-shaped hook 53 and the counterweight 56 ​​to prevent the steel pipe 9 from rotating along with the transport component 5 due to excessive rotation speed. After the stopper 57 is set, the stopper 57 will press the counterweight 56 ​​and the arc-shaped hook 53, thereby ensuring that the arc-shaped hook 53 can face the set opening, ensuring that the steel pipe 9 slides into the storage component 6.

[0074] In this embodiment, the transport assembly 5 is connected to the rotating disk 25 via a telescopic tube 52. The ends of the telescopic tube 52 are connected to the connecting rod 54 and the rotating disk 25, respectively, so that the transport assembly 5 and the rotating disk 25 can rotate synchronously within the second housing 8. It should be understood that the telescopic length of the telescopic tube 52 is sufficient to meet the maximum displacement length of the rotating disk 25 within the second housing 8. Furthermore, the telescopic tube 52 ensures the linkage between the transport assembly 5 and the rotating disk 25.

[0075] In this embodiment, reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The fixing assembly 3 is provided on the first box body 21 to fix the steel pipe 9 to be cut.

[0076] The fixing assembly 3 includes: a door frame 31, the open side of which faces downward and is fixed to the first box body 21. It should be understood that welding or bolt connection can be used to fix the door frame 31 to the first box body 21; a second threaded rod 32, which is threadedly connected to the door frame 31, and the lower end of the second threaded rod 32 passes through the door frame 31; a connecting pipe 34, which is detachably connected to the lower end of the second threaded rod 32 by a bolt; at least two curved plates 33, the two curved plates 33 are arranged in the door frame 31, the two curved plates 33 are coaxially arranged, and the two curved plates 33 are rotatably connected to the second ends of the second threaded rod 32; wherein the steel pipe 9 can pass through the door frame 31 and the arc-shaped hook 53 of the transport assembly 5 and touch the limiting groove of the rotating disk 25, and the steel pipe 9 is fixed by rotating the second threaded rod 32 so that the curved plate 33 touches and fixes the steel pipe 9.

[0077] In this embodiment, two curved plates 33 are provided, and the two curved plates 33 are fitted together, that is, the two curved plates 33 have different diameters, which can achieve the fixation of steel pipes 9 of various diameters. A connecting tube 34 is provided to rotatably connect the two curved plates 33, and a limit stop is provided at the lower end of the connecting tube 34 so that the connecting tube 34 can lift the two curved plates 33. By screwing and adjusting the second threaded rod 32, the curved plates 33 can be moved up and down to achieve the fixation and release of the steel pipe 9. It should be understood that screwing the second threaded rod 32 downward causes the curved plate 33 to move downward, thereby clamping the cut steel pipe 9.

[0078] In this embodiment, reference Figure 1 and Figure 2 The cutting assembly 4 includes a cantilever rod 41 connected to the first housing 21; a telescopic rod 42 provided on the cantilever rod 41 and capable of vertically extending downward; and a cutter 43 connected to the lower end of the telescopic rod 42. The cutting line of the cutter 43 coincides with the end surface of the first end of the first housing 21. The telescopic rod 42 enables the cutter 43 to move up and down, thereby cutting the steel pipe 9.

[0079] In this embodiment, the telescopic rod 42 is connected to the cutting machine 43 via a buffer; the provided buffer can play a buffering role, thereby effectively preventing the motor and blade in the cutting machine 43 from being damaged when they collide hard with the steel pipe 9 during the process of the cutting machine 43 cutting the steel pipe 9.

[0080] The buffer member includes: a third housing 44, within which a second spring 45 is disposed, the second spring 45 being connected to the upper end of the third housing 44; and a limiting rod 46 slidably disposed within the third housing 44 and connected to the second spring 45. The limiting rod 46 extends from the lower end of the third housing 44 and is connected to the cutter 43. It should be understood that the second spring 45 allows the cutter 43 to contact the steel pipe 9 and provide a buffering effect when the cutter 43 moves downward, while the limiting rod 46 prevents the cutter 43 from escaping from the third housing 44. It also ensures that the limiting rod 46 is limited by the third housing 44 during the retraction of the telescopic rod 42, thereby lifting the cutter 43.

[0081] In this embodiment, the cutting device also includes a controller 7, which is electrically connected to the telescopic rod 42 and the cutting machine 43 respectively; the telescopic rod 42 is an electric telescopic rod 42; wherein, the controller 7 can control the extension and retraction of the telescopic rod 42 and the switch of the cutting machine 43 to cut the steel pipe 9.

[0082] In this embodiment, the specific method of using the cutting device, that is, the specific method of cutting the steel pipe 9 is as follows: first, set the length of the steel pipe 9 to be cut, then set the cutting length through the slider 24 and the size rod 22, pass the steel pipe 9 to be cut through the door frame 31 of the fixing component 3, then pass it through the arc hook 53 in the transport component 5, and finally pass the steel pipe 9 into the groove provided on the rotating disk 25, and push the steel pipe 9 so that the steel pipe 9 is directed toward Figure 2 The first housing 21 is used to move the steel pipe 9 to the right until the slider 24 is limited by the first housing 21. At this time, the steel pipe 9 will push the rotating disk 25 to the right and extend the telescopic rod 42. At this time, the steel pipe 9 to be cut is set to the cutting length. The second threaded rod 32 of the fixing assembly 3 can then be screwed downward to fix the steel pipe 9 to be cut. The controller 7 can then be used to control the opening of the telescopic rod 42 and the cutting machine 43, thereby achieving the cutting of the steel pipe 9. When the steel pipe 9 is cut, the controller 7 can control the retraction of the telescopic rod 42 and the closing of the cutting machine 43. The cut steel pipe 9 is transported by the transport assembly 5 to the storage assembly 6. The operator can directly obtain the steel pipe 9 of the length that meets the use requirements from the storage assembly 6.

[0083] After the cut steel pipe 9 falls into the storage assembly 6, the first spring 23 on the first box body 21 will shrink, pulling the slider 24 back to its original position ( Figure 1 The middle slider 24 is positioned), and then the rotating disk 25 is pulled back to prepare for the next steel pipe 9 cutting.

[0084] The construction steel pipe cutting device provided in the present application can realize the size positioning of the steel pipe 9 to be cut through the set measuring component 2, making the measurement operation of the cutting length of the steel pipe 9 simpler, and realizes the fixation of the steel pipe 9 to be cut through the fixing component 3, making the steel pipe 9 to be cut more stable and the cutting length more accurate. The cut steel pipe 9 can be directly transported to the storage component 6 via the transportation component 5, and the cut steel pipe 9 can be directly taken out from the storage component 6, which improves the operating efficiency and meets the use requirements.
