Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a pipe circumferential cutting machine. Background Technology

[0002] With the rapid development of infrastructure construction and the increasing awareness of environmental protection, circumferentially slotted explosive charges are currently used to improve the energy utilization rate of explosive detonations. A circumferentially slotted explosive charge consists of a commonly used explosive cartridge and an outer circumferentially slotted tube. The explosive cartridge is a pre-fabricated industrial product, and its outer circumferentially slotted tube is made of anti-static PVC plastic tubing with multiple circumferential slits processed on its surface. When the circumferentially slotted explosive charge detonates, the stress difference between the slits and non-slits in the tube outside the charge creates stress concentration at the slits, thereby altering the circumferential energy distribution during the explosion and improving the energy utilization rate. The circumferentially slotted explosive charge blasting is beneficial for improving the construction efficiency of the drill-and-blast method and has good economic benefits.

[0003] The circumferential cutting of existing pipes is usually done manually with a small handheld cutting machine. This is labor-intensive and has low precision. After long-term operation, the small cutting machine heats up severely, which shortens its service life. Utility Model Content

[0025] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0026] like Figure 1 As shown, the pipe circumferential cutting machine provided in this embodiment includes an operating platform 1, a first track 2, a second track 3, a clamp 5, a cutting machine 6, a drive source 23 for driving the cutting machine 6, a propulsion track 21 arranged parallel to the second track 3, and a mounting frame 26 slidably connected to the propulsion track 21.

[0027] The operating platform 1 has a length direction X and a width direction Y. Support legs 27 are provided around its bottom perimeter. The first track 2 is located on one side of the operating platform 1 in the Y direction and extends along the X direction. The second track 3 is located beside the first track 2 and extends along the Y direction. Two second tracks 3 are arranged parallel to each other in the X direction, and a propulsion track 21 is arranged between the two second tracks 3.

[0028] Both the first track 2 and the second track 2 are provided with U-shaped grooves. The upper surfaces of both the first track 2 and the second track 2 are provided with scale lines 8. Two clamps 5 are slidably connected on the first track 2, and one cutting machine 6 is connected to each of the second tracks 3.

[0029] like Figure 2 As shown, the clamping platform 5 includes a first base 7, a base 24, a fixed block 25, a movable block 10, a clamping cavity 4, a screw 12, and a pointing mark 22. The upper end of the first base 7 is connected to the base 24, and the lower end of the first base 7 is a cylinder or cuboid adapted to the U-shaped groove on the first track 2. The base 24 extends along the Y direction, and one end is fixedly connected to the fixed block 25. The screw 12 is threadedly connected to the fixed block 25. One end of the screw 12 is connected to the movable block 10, and the other end extends to the outside of the fixed block 25 and is connected to an adjusting handle 11. By rotating the adjusting handle 11, the movable block 10 can be moved closer to or further away from the fixed block 25, causing the clamping cavity 4 between the movable block 10 and the fixed block 25 to shrink to clamp the pipe or expand to loosen the pipe. To achieve flexibility in the displacement of the movable block 10, a groove or slide rail can be provided on the base 24, and the movable block 10 is placed in the groove or connected to the slide rail. The upper ends of both the movable block 10 and the fixed block 25 protrude to a certain height to clamp pipes with a diameter of 60mm or less. The directional mark 22 is set on the first base 7 and corresponds to the scale line 8 on the first track 2.

[0030] Additionally, a locking rod extending in the Y direction can be provided on the first track 2, with the locking rod extending out and abutting against the first base 7 to lock the moving position of the clamp 5.

[0031] like Figure 3 As shown, the cutting machine 6 includes a second base 9, a control frame 16 disposed on the upper end of the second base 9, and a blade 14 rotatably mounted on the control frame 16. The lower end of the second base 9 is a cylinder or cuboid adapted to the U-shaped groove on the second track 3. A safety cover 13 is provided on the side of the control frame 16 away from the first track 2. The safety cover 13 and the control frame 16 can shield some cutting debris and protect the operator's safety. A push handle 15 is provided on the outer surface of the control frame 16. The push handle 15 allows the operator to move the cutting machine 6 and the drive source 23 closer to or away from the pipe.

[0032] like Figure 1 , Figure 4As shown, the mounting bracket 26 is slidably connected to the feed rail 21, and the drive source 23 is mounted on the mounting bracket 26. The drive source 23 includes a power switch 17, a wire 18, a rotating shaft 19, and a drive motor 20. The power switch 17 is connected to the drive motor 20 via the wire 18. The drive motor 20 is connected to the rotating shaft 19 via gear engagement. The rotating shaft 19 is connected to the rotating shaft of the blade 14. The drive motor 20 drives the rotating shaft 19 to rotate, thereby driving the blade 14 to rotate and achieve cutting.

[0033] Alternatively, the power switch 17 can be installed at one end of the propulsion track 21, and the wire 18 can be a flexible and retractable cable.

[0034] The working principle of the pipe circumferential cutting machine provided by this utility model is as follows: In the initial state, the two clamps 5 on the first track 2 are in a loose state. When the operation begins, the two clamps 5 are first adjusted to the required interval length (by means of the directional mark 22 on them and the scale line 8 on the first track 2), and then the clamps 5 are locked by the locking rod.

[0035] Place the pipe in the clamping cavity 4, rotate the adjusting handle 11 to bring the movable block 10 close to the pipe and work together with the fixed block 25 to clamp the pipe.

[0036] Turn on the power to the cutting machine, and use the push handle 15 to push the cutting machine 6 close to the pipe. Turn on the power switch 17, rotate the blade 14, and slowly advance the cutting machine 6 to cut the pipe. Two cuts can be made at a time. After completion, turn off the power switch 17 and remove the cutting machine 6.

[0037] Using the cut seam as a reference, and in conjunction with the scale line 8 on the first track 2, loosen the clamp 5, move the pipe to the position where the next cut seam needs to be made, and repeat the above steps until all cut seams are completed.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
