Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, specifically to a pipe cutting device for building engineering. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] In construction projects, pipes are often cut. However, current cutting techniques generally involve manual cutting using cutting machines, which results in poor cutting quality and requires subsequent grinding. Cutting with equipment is also an option, but the equipment is large and inconvenient to use. Furthermore, the inability to accurately place the pipes also leads to poor cutting quality. Utility Model Content

[0006] The main ring body is connected to a support ring frame on the front side. The support ring frame is provided with a limiting ring groove on the front side. A limiting slider is provided in the limiting ring groove for limiting and sliding. The limiting slider extends to the outside and is connected to a drive frame. A cutting device is provided on the front side of the drive frame for lifting and driving.

[0009] Furthermore, the auxiliary drive box has a first bevel gear and a second bevel gear rotatably connected to one side and the bottom, respectively. The first bevel gear is connected to the adjusting screw, and the second bevel gear is connected to a torsion handle extending to the outside, which facilitates the lifting and lowering of the drive cutting device.

[0010] Furthermore, a limiting ring frame is connected to the outer side of the support ring frame, and a ring groove is provided on the outer side of the limiting ring frame. An auxiliary frame extending into the ring groove is connected to the rear side of the drive frame to facilitate auxiliary limiting and stable rotation operation.

[0011] Furthermore, an auxiliary handle is connected to the top of the auxiliary frame, and a rubber sleeve is connected to the outside of the auxiliary handle to facilitate auxiliary rotation operations.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3A pipe cutting device for construction engineering includes a main ring body 1. A clamping half-ring 3 is connected to the inner side of the main ring body 1. A hand-tightening bolt 2, which is threadedly connected to the rear end of the clamping half-ring 3, is connected to the main ring body 1. In actual use, it is often necessary to place the round pipe on a support structure, such as a table, and then put the main ring body 1 on it. The hand-tightening bolt 2 drives the clamping half-ring 3 to move inward, thereby clamping the round pipe. In actual operation, it is necessary to ensure that the round pipe is in the center position of the main ring body 1, that is, the positions of the clamping half-rings 3 on both sides are consistent.

[0019] The main ring body 1 is connected to a support ring frame 4 on its front side. The support ring frame 4 is provided with a limiting ring groove 5 on its front side. A limiting slider 6 is provided in the limiting ring groove 5 for limiting and sliding. The limiting slider 6 extends to the outside and is connected to a drive frame 7. A cutting device 11 is provided on the front side of the drive frame 7 for lifting and lowering. The cutting device 11 includes a battery box 12, a main drive box 13, and a cutting box 14 arranged sequentially from top to bottom. A cutting blade 15 is rotatably connected to the bottom of the cutting box 14. A drive motor 16 is connected to the outside of the cutting box 14 to drive the cutting blade 15 to rotate. When the round tube is clamped, the cutting device 11 is driven to rise and fall by the drive frame 7. When the cutting device 11 is in contact with the round tube, the drive motor 16 is started to drive the cutting blade 15 to rotate. Then, the cutting device 11 is driven to rise and fall by the drive frame 7 again to cut. After the cutting begins, the round tube can be cut in a ring shape by the rotation of the drive frame 7. Because the clamping half ring 3 has already clamped the round tube, the cutting plane can be well guaranteed, and no post-grinding is required.

[0020] The drive frame 7 has a limiting groove 8 on its front side. An adjusting screw 9 is rotatably connected in the limiting groove 8. A limiting block 10, threadedly connected to the adjusting screw 9, is provided in the limiting groove 8 to limit movement. The limiting block 10 is fixedly connected to the main drive box 13 for operation. A secondary drive box 22, which drives the adjusting screw 9 to rotate, is connected to the top of the drive frame 7. A first bevel gear 23 and a second bevel gear 24, which mesh with each other, are rotatably connected to one side and the bottom of the secondary drive box 22, respectively. The first bevel gear 23 is connected to the adjusting screw 9. The second bevel gear 24 is connected to a torsion handle 25 extending to the outside. In actual use, by torsion of the handle 25, the first bevel gear 23 and the second bevel gear 24 can drive the adjustment screw 9 to rotate, thereby driving the lifting and lowering of the limiting block 10 and the cutting device 11.

[0021] The support ring frame 4 is connected to a limiting ring frame 17 on its outer side. The limiting ring frame 17 has an annular groove 18 on its outer side. The drive frame 7 is connected to an auxiliary frame 19 extending to the annular groove 18 on its rear side. The auxiliary frame 19, in conjunction with the annular groove 18, can further ensure rotational stability. The top of the auxiliary frame 19 is connected to an auxiliary handle 20. The outer side of the auxiliary handle 20 is connected to a rubber sleeve 21. In actual use, the auxiliary handle 20 and the rubber sleeve 21 can drive the drive frame 7 and the cutting device 11 to perform a stable annular rotation operation.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
