In addition, traditional steel structure cutting devices are not convenient for adjusting the cutting length of the building steel pipe, which further leads to low cutting efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a building steel structure cutting device, which can clamp the building steel pipe during cutting and release the building steel pipe after cutting, and is also convenient for adjusting the cutting length of the steel pipe to improve cutting efficiency.

[0007] Further description, it also includes bolts and nuts. The bottom of the limit seat is connected with the bolt through a thread. The limit seat is slidably connected with the nut, and the nut is rotatably connected to the bolt.

[0008] Further explanation: four brackets are provided at the bottom of the support base.

[0009] The beneficial effects of the utility model are as follows: first, the construction steel pipe to be cut is manually placed on the two clamping shafts of the fixed sleeve rod, and then the electric slider is manually started, and the saw blade will cut the construction steel pipe on the limit seat, and this process is repeated in sequence, thereby realizing automatic cutting of the construction steel pipe and improving the cutting efficiency of the construction steel pipe.

[0016] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0017] Embodiment 1: A building steel structure cutting device, such as Figure 1-Figure 3 As shown, it includes a support base 1, a slide rail 2, an electric slider 3, a saw blade 4, a limit seat 5 and a fixed sleeve rod 6. The support base 1 has two grooves, which are symmetrically arranged. Four brackets are arranged at the bottom of the support base 1. A slide rail 2 is welded on the top of the support base 1. The top of the slide rail 2 is slidably connected to the electric slider 3. The saw blade 4 is rotatably connected to the electric slider 3. A limit seat 5 is welded on the support base 1. The limit seat 5 is a quadrangular pyramid structure. A fixed sleeve rod 6 is welded on the side of the support base 1 away from the electric slider 3. Two clamping shafts are arranged on the upper part of the fixed sleeve rod 6. The two clamping shafts of the fixed sleeve rod 6 are convenient for clamping the construction steel pipe. The two clamping shafts on the fixed sleeve rod 6 are both vertically arranged.

[0018] First, the construction steel pipe to be cut is manually placed on the two clamping shafts of the fixed sleeve rod 6, and the top of the limit seat 5 contacts the construction steel pipe. Then the electric slider 3 and the saw blade 4 are manually started, so that the electric slider 3 moves back and forth along the slide rail 2, and the electric slider 3 drives the saw blade 4 to move back and forth. The saw blade 4 will cut the construction steel pipe on the limit seat 5, so that the cut construction steel pipe falls from the groove on the support base 1, and the saw blade 4 continues to move. The construction steel pipe moves downward under the action of gravity, and the saw blade 4 cuts the construction steel pipe on the limit seat 5 again. This is repeated in sequence, which can realize the automatic cutting of the construction steel pipe and improve the cutting efficiency of the construction steel pipe.

[0019] Embodiment 2: Based on embodiment 1, Figure 1-Figure 3 As shown, it also includes a bracket 7, a moving rod 8, a buckle 9, a spring 10, a short rack 11, a long rack 12 and a gear 13. The bracket 7 is welded on the support base 1. Two moving rods 8 are slidably connected to the bracket 7. The two moving rods 8 are symmetrically arranged. One end of one of the moving rods 8 is in contact with the electric slider 3. The two moving rods 8 are provided with a buckle 9 at one end close to the bracket 7. The two buckles 9 are semicircular structures. The two buckles 9 are convenient for clamping the construction steel pipe. A spring 10 is connected to the top of each buckle 9 through a hook. A short rack 11 is provided on one of the moving rods 8 close to the electric slider 3, and a long rack 12 is provided on one of the moving rods 8 away from the electric slider 3. A gear 13 is rotatably connected to the top of the bracket 7, and the gear 13 is meshed with both the short rack 11 and the long rack 12.

[0020] At first, the electric slider 3 is against one of the moving rods 8, the two springs 10 are compressed, and the gear 13 is meshed with the short rack 11 and the long rack 12. When the electric slider 3 drives the saw blade 4 to move back and forth, the electric slider 3 will be disengaged from one of the moving rods 8, and one of the springs 10 will be reset and drive the short rack 11, one of the buckles 9 and one of the moving rods 8 to move toward the direction of the building steel pipe. The short rack 11 will drive the gear 13 to rotate, and the rotation of the gear 13 drives the long rack 12, the other moving rod 8 and the other buckle 9 to move toward the direction of the building steel pipe. The other spring 10 will be reset, so that the two buckles 9 clamp the building steel pipe, and the saw blade 4 will move toward the building steel pipe. The cutting is carried out, and then the electric slider 3 continues to move and contacts with another moving rod 8. The electric slider 3 pushes the other moving rod 8 and the other buckle 9 to move away from the building steel pipe, so that one of the buckles 9 moves away from the building steel pipe, thereby causing the two buckles 9 to release the building steel pipe, and the building steel pipe moves downward, and the bottom of the building steel pipe contacts with the top of the limit seat 5 again, and repeats in sequence. It can intermittently clamp the building steel pipe, clamp the building steel pipe during cutting, make the cutting process more stable, and make the cross-section of the building steel pipe smoother. After cutting, the building steel pipe is released to facilitate continuous cutting of the building steel pipe, thereby further improving the cutting efficiency of the building steel pipe.

[0021] Embodiment 3: Based on embodiment 2, Figure 3 As shown, it also includes a bolt 14 and a nut 15. The bottom of the limiting seat 5 is connected to the bolt 14 through a thread, and the limiting seat 5 is slidably connected to the nut 15. The nut 15 is rotatably connected to the bolt 14.

[0022] The bottom of the construction steel pipe is in contact with the top of the limit seat 5. When the construction steel pipe needs to be cut according to the length of the construction steel pipe, the bolt 14 is manually rotated according to the required length. The rotation of the bolt 14 will drive the nut 15 to move upward, and the nut 15 will drive the construction steel pipe to move upward. The bolt 14 is manually rotated in the opposite direction, and the bolt 14 will drive the nut 15 to move downward, so that the construction steel pipe moves downward, so that the placement height of the construction steel pipe can be adjusted, and then construction steel pipes of different lengths can be cut to meet the needs of different occasions and further improve the efficiency of cutting construction steel pipes.
