Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe cutting, and more specifically, particularly relates to a steel pipe cutting device for building construction engineering. Background Art

[0002] In the construction of buildings, a large number of building materials will be transported and installed. Among them, steel pipes, as one of the mainstream materials, are often used as supports or conveying pipes. When steel pipes are transported to the construction site, they are often long. When used in different places, cutting equipment is required for cutting.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment:

[0026] like Figure 1-4 As shown, a steel pipe cutting equipment for building construction engineering includes an operating table 1 and a first fixing mechanism 3 and a second fixing mechanism 4 arranged on the operating table 1 for fixing the steel pipe 2. A cutting machine 6 for cutting the steel pipe 2 is fixedly installed on the operating table 1, and the cutting machine 6 is located between the first fixing mechanism 3 and the second fixing mechanism 4. The model of the cutting machine 6 is a J3G4-400 profile cutting machine. The first fixing mechanism 3 slides on the operating table 1, and the second fixing mechanism 4 is fixed on the operating table 1. A moving mechanism 5 is connected between the first fixing mechanism 3 and the second fixing mechanism 4. The moving mechanism 5 can drive the first fixing mechanism 3 to move closer to or away from the second fixing mechanism 4, and can fix steel pipes 2 of different lengths during cutting. By setting two fixing mechanisms to clamp the steel pipe 2, the stability during cutting of the steel pipe 2 is improved, and the two sections of the steel pipe 2 can be processed separately after cutting.

[0027] like Figure 1-4As shown, two third long holes 11 are symmetrically opened on the operating table 1, and the first fixing mechanism 3 includes a first mounting frame 31 that penetrates and slides in the third long hole 11. The inner side wall and the outer side wall of the first mounting frame 31 in the vertical direction are fixedly connected to the limit block 311. The two limit blocks 311 located on the same side wall are respectively fitted with the upper end surface and the lower end surface of the operating table 1 to limit the displacement of the first mounting frame 31 in the vertical direction. The upper end of the first mounting frame 31 is provided with a first long hole 32 connected with the interior thereof, and the first clamping member 33 and the second clamping member 34 are penetrated and slid in the first long hole 32. The first clamping member 33 and the second clamping member 34 are provided with an opening on the side close to each other for clamping the steel pipe 2. In this embodiment The first fixing mechanism 3 also includes a first rotating rod 35, one end of which is rotatably connected to the first mounting frame 31 through a bearing seat (not shown in the figure), and a first servo motor 36 is fixedly installed on one side of the first mounting frame 31. The other end of the first rotating rod 35 passes through and rotates on the first mounting frame 31 and is fixedly connected to the output end of the first servo motor 36. The first rotating rod 35 is located in the first mounting frame 31 and has an external thread with opposite textures. The first rotating rod 35 passes through and is threadedly connected to the lower ends of the first clamping member 33 and the second clamping member 34. The first clamping member 33 and the second clamping member 34 are respectively connected to the external threads with opposite textures. The first servo motor 36 rotates the first rotating rod 35, and since the first clamping member 33 and the second clamping member 34 are respectively connected to the threads with opposite textures, the first clamping member 33 and the second clamping member 34 are close to each other to clamp the steel pipe 2 and adapt to steel pipes 2 of different diameters.

[0028] like Figure 1-4As shown, the second fixing mechanism 4 includes a second mounting frame 41 that penetrates and is fixedly connected to the operating table 1, and a second elongated hole 42 that is connected to the interior of the second mounting frame 41 is opened at the upper end thereof, and a third clamping member 43 and a fourth clamping member 44 are inserted and slidably in the second elongated hole 42, and the third clamping member 43 and the fourth clamping member 44 are opened on the side close to each other and are the same as the opening of the first clamping member 33 or the second clamping member 34 and are used to clamp the steel pipe 2; the second fixing mechanism 4 also includes a second mounting frame 41 that is rotatably connected to the operating table 1 through a bearing seat (not shown in the figure) at one end thereof. The second rotating rod 45 in the second mounting frame 41 has a second servo motor 46 fixedly mounted on one side of the second mounting frame 41. The other end of the second rotating rod 45 penetrates and rotates on the second mounting frame 41 and is fixedly connected to the output end of the second servo motor 46. The second rotating rod 45 located in the second mounting frame 41 has an external thread with opposite patterns, and the second rotating rod 45 penetrates and is threadedly connected to the lower ends of the third clamping member 43 and the fourth clamping member 44. The third clamping member 43 and the fourth clamping member 44 are respectively connected to the external threads with opposite patterns. The second rotating rod 45 is driven to rotate by the rotation output of the second servo motor 46, so that the third clamping member 43 and the fourth clamping member 44 are close to each other and clamp the steel pipes 2 of different diameters.

[0029] like Figure 1-4 As shown, the moving mechanism 5 includes a first connecting plate 51 fixedly connected to the second mounting frame 41 and a second connecting plate 52 fixedly connected to the first mounting frame 31, the end of the second connecting plate 52 away from the first mounting frame 31 slides in the first connecting plate 51, the lower end surface of the second connecting plate 52 is fixedly connected to the third connecting plate 53, the lower end surface of the first connecting plate 51 is fixedly installed with a third servo motor 54, the output end of the third servo motor 54 is fixedly connected to a threaded rod 55, and the free end of the threaded rod 55 penetrates and is threadedly connected to the third connecting plate 53. The threaded rod 55 is rotated by the rotation output of the third servo motor 54, and the threaded rod 55 rotates through the connection of the third connecting plate 53 to make the second connecting plate 52 slide in the first connecting plate 51. Since the second connecting plate 52 is fixedly connected to the first mounting frame 31, the first mounting frame 31 can slide in the third long strip hole 11, thereby moving the first fixing mechanism 3 relative to the second fixing mechanism 4, adjusting the distance between the two fixing mechanisms, and clamping and fixing steel pipes 2 of different lengths according to needs.

[0030] like Figure 5As shown, the arc-shaped openings of the first clamping member 33, the second clamping member 34, the third clamping member 43 and the fourth clamping member 44 are all provided with pads 7 that are adapted to the shapes of their openings. The pads 7 are made of rubber material to prevent the clamping members from causing damage to the steel pipe 2 when fixing it; the bottom ends of the openings of the first clamping member 33, the second clamping member 34, the third clamping member 43 and the fourth clamping member 44 are fixedly connected with inclined blocks 8. When the steel pipe 2 enters between the two clamping members, it is first placed on the first mounting frame 31 or the second mounting frame 41. When the two clamping members approach each other, by setting the inclined blocks 8, the inclined surfaces of the two inclined blocks 8 squeeze the steel pipe 2 and push it between the arc-shaped openings of the two clamping members in the process of approaching each other, so that the two clamping members continue to approach each other to fix the steel pipe 2.

[0031] like Figure 1-4 As shown, a steel pipe cutting device for building construction engineering also includes a storage mechanism 9, which is arranged on the side of the first fixing mechanism 3 away from the second fixing mechanism 4. The storage mechanism 9 includes two symmetrically arranged fixing frames 91 fixedly connected to the upper end surface of the operating table 1, and a plurality of rollers 92 are arranged between the two fixing frames 91. The two ends of the rollers 92 are respectively rotatably connected to the adjacent fixing frames 91. It also includes a baffle 93 fixedly connected to the fixing frame 91. The opening shape of the baffle 93 is the same as the opening shape of the first clamping member 33. In this embodiment, the baffle 93 is arc-shaped, and the highest point of the roller 92 is flush with the upper end surface of the first mounting frame 31. The upper end surface of the first mounting frame 31 is flush with the upper end surface of the second mounting frame 41. By setting the storage mechanism 9, the steel pipe 2 to be cut can be placed in the storage mechanism 9, and by setting the rollers 92, it is convenient to push the steel pipe 2 to the first fixing mechanism 3 or the second fixing mechanism 4 for fixing, and the baffle 93 is arranged to prevent the steel pipe 2 from rolling to the side.

[0032] The first servo motor 36, the second servo motor 46, the third servo motor 54 and the cutting machine 6 are all electrically connected to an external power supply. The first servo motor 36, the second servo motor 46, the third servo motor 54 are electrically connected to a control unit (not shown in the figure). The model of the first servo motor 36, the second servo motor 46, the third servo motor 54 is HGHN43J.

[0033] The working principle of a steel pipe cutting device for building construction engineering in this embodiment is as follows: when in use, firstly, the steel pipes 2 are placed in the storage mechanism 9, the initial position of the first fixing mechanism 3 is located on the side of the third long hole 11 close to the storage mechanism 9, the steel pipe 2 is pushed between the first clamping member 33 and the second clamping member 34, and according to the length of the steel pipe 2, the first fixing mechanism 3 is moved to a suitable position by the output of the third servo motor 54, until the end of the steel pipe 2 close to the second fixing mechanism 4 enters between the third clamping member 43 and the fourth clamping member 44, and the first servo motor 36 and the second servo motor 46 are rotated and output, The first clamping member 33 and the second clamping member 34 are brought close to each other, and the third clamping member 43 and the fourth clamping member 44 are brought close to each other. Through the pushing of each inclined block 8, the tube body of the steel pipe 2 is made to enter between the openings of the first clamping member 33 and the second clamping member 34 and the openings of the third clamping member 43 and the fourth clamping member 44. Finally, the first fixing mechanism 3 and the second fixing mechanism 4 can fix steel pipes 2 of different lengths. After that, the steel pipe 2 is cut by the cutting machine 6. The two sections after cutting will not fall off. Moreover, since the first fixing mechanism 3 and the second fixing mechanism 4 can be operated separately, the two sections of the steel pipe 2 can be processed separately after cutting.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
