Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cutting devices, and in particular to an underground oil and gas pipeline cutting device. Background Art

[0002] An underground oil and gas pipeline is a complex system that transports energy materials such as crude oil and natural gas from their sources of production to their consumption. It consists of a series of pipelines, which are usually buried underground to reduce the impact on the environment and improve transportation efficiency. During the construction of underground oil and gas pipelines, the pipes are cut with the help of a cutting device. The cutting device is a device that cuts and separates materials by shearing or grinding. Its basic working principle is to use an internal or external driving source to cause the cutting tool to generate shear force or grinding force on the material, thereby causing the material to break or cut. When the cutting device is turned on, the cutting tool begins to rotate and cuts the material according to the instructions of the control system. In this process, the cutting tool will generate shear force or grinding force on the material, causing the material to gradually break and separate from the body. Since the position of the pipeline during the cutting process directly affects the cutting effect, it is necessary to perform cutting limit and stabilization operations on the pipeline.

[0003] In the related art, when the cutting device is used, a clamping frame is generally used to clamp and position the pipeline during the cutting process to ensure stability during the pipeline cutting process, so that the cutting device can be used.

[0004] However, during the current use of the cutting device, when the pipe is clamped for stability, the entire pipe is in a fixed state, and the pipe is set in a hollow circular shape, which makes it difficult for the cutting tool to make circumferential contact with the pipe cutting position during cutting. When the pipe size is large, the staff needs to repeatedly loosen the clamped pipe and adjust the cutting position of the pipe before performing circumferential cutting and separation operations on the pipe, which affects the convenience and stability of pipe cutting.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] Reference Figures 1-4 The utility model provides a technical solution: an underground oil and gas pipeline cutting device, including a cutting table 1 and a cutting stabilization mechanism.

At the same time, it is convenient for the user to rotate the pipeline so that the cutting knife 2 performs a circular cutting operation on the pipeline, avoiding the difficulty in adjusting the stability and cutting position during the pipeline cutting process, thereby improving the cutting convenience and stability of the cutting knife 2.

[0031] Reference Figures 1-4 In a preferred embodiment, the cutting stabilization mechanism includes a stabilizing seat 4, which is movably connected to both sides of the top of the cutting table 1, and a force-applying rod 6 is movably connected to the front side of the top of the stabilizing seat 4. Contact wheels 7 are installed on both sides of the stabilizing seat 4, the force-applying rod 5 and the force-applying rod 6 through axle pins. The force-applying connection mechanism is arranged at the bottom of both sides of the stabilizing seat 4. The pipe to be cut is placed on the top of the stabilizing seat 4, and the pipe is located inside the force-applying rod 5 and the force-applying rod 6. Then, the force-applying rod 6 is moved to contact the surface of the pipe, so that the force-applying rod 6 cooperates with the force-applying rod 5 to clamp and stabilize the pipe. At the same time, the contact wheel 7 contacts the surface of the pipe, preparing for the subsequent user to rotate the pipe for cutting operation, and then push the stabilizing seat 4 to cooperate with the force-applying rod 6 and the force-applying rod 5 to drive the pipe It contacts the cutting knife 2, so that the cutting knife 2 contacts the pipe for cutting. At the same time, the pipe can be rotated according to the actual size of the pipe, so that the cutting knife 2 performs circular cutting on the pipe. At this time, since the contact wheel 7 can only rotate back and forth, it ensures that the pipe can rotate in a circular motion while ensuring the stability of the pipe. The force connection mechanism includes a connecting groove 8, a connecting seat 9 and a connecting frame 10. The connecting groove 8 is opened at the bottom of both sides of the stable seat 4. The connecting seat 9 is movably connected to the inside of the connecting groove 8. The connecting frame 10 is fixedly connected to the top of the connecting seat 9. The inner side of the connecting frame 10 is fixedly connected to the outer side of the force rod 6, and the force translation connection between the force rod 6 and the stable seat 4 can be performed to avoid the force rod 6 from being separated from the stable seat 4 when in use, thereby improving the stability of the force rod 6.

[0032] Reference Figure 2-Figure 4In a preferred embodiment, a positioning groove 11 is provided on the top of the stabilizing seat 4, and a positioning bar 12 located inside the positioning groove 11 is movably connected to the front side of the top of the stabilizing seat 4, so that the force rod 6 and the stabilizing seat 4 can be translated and positioned, thereby avoiding the situation where the force rod 6 is difficult to translate and position when in use, thereby improving the positioning convenience of the force rod 6, and a lifting port 13 is provided at the bottom of the front side of the force rod 6, and a lifting seat 14 is movably connected inside the lifting port 13, and the bottom of the lifting seat 14 is fixedly connected to the top of the positioning bar 12, so that the positioning bar 12 and the force rod 6 can be lifted and connected, thereby ensuring the connection effect between the positioning bar 12 and the force rod 6.

[0033] Reference Figure 2-Figure 4 In a preferred embodiment, a lifting rod 15 located in front of the force-applying rod 6 is movably connected to the top of the stabilizing seat 4, and the rear side of the lifting rod 15 is fixedly connected to the front side of the lifting seat 14. This can provide the user with a force-applying medium for synchronously moving the two lifting seats 14, thereby ensuring the convenience of using the lifting seats 14. A limiting opening 16 is provided inside the lifting seat 14, and a limiting rod 17 located inside the limiting opening 16 is fixedly connected to the inner wall of the lifting opening 13, which can perform lifting and limiting work between the lifting seat 14 and the lifting opening 13, thereby improving the lifting stability of the lifting seat 14.

[0034] Reference Figure 2-Figure 4 In a preferred embodiment, by inlaying and connecting magnetic sheets 18 on both sides of the limiting rod 17, and inlaying and connecting magnetic strips 19 on both sides of the inner wall of the limiting opening 16, the lifting seat 14 and the positioning strip 12 can be magnetically positioned by the lifting seat 14 after lifting and moving, thereby improving the convenience of using the lifting seat 14 and the positioning strip 12.

[0035] Specifically, the working process or working principle of the underground oil and gas pipeline cutting device is as follows: when in use, first move the pipe to be cut and place it on the top of the stabilizing seat 4, and make the pipe located inside the force-bearing rod 5 and the force-applying rod 6, then move the force-applying rod 6 to contact the surface of the pipe, so that the force-applying rod 6 cooperates with the force-bearing rod 5 to clamp and stabilize the pipe. At this time, the connecting frame 10 drives the connecting seat 9 to follow the force-applying rod 6 to move inside the connecting groove 8, and performs translational connection between the force-applying rod 6 and the stabilizing seat 4. At the same time, the contact wheel 7 contacts the surface of the pipe, preparing for the subsequent user to rotate the pipe for cutting operation, and then hold the lifting rod 15 to move the lifting seat 14 to drive the positioning bar 12 to move downward into the positioning groove 11, so that the positioning column cooperates with the lifting seat 14 to plug between the force-applying rod 6 and the stabilizing seat 4 Positioning work. During this process, the limit rod 17 moves inside the limit mouth 16 to perform lifting and limiting work between the lifting seat 14 and the force rod 6. At the same time, the magnetic sheet 18 cooperates with the magnetic strip 19 to magnetically position the lifted lifting seat 14 and the positioning strip 12. Subsequently, the stabilizing seat 4 is pushed to cooperate with the force rod 6 and the force-bearing rod 5 to drive the pipe to contact the cutting knife 2, so that the cutting knife 2 contacts the pipe for cutting. At this time, the translation rail 21 moves inside the translation mouth 20 to perform translation connection and anti-deviation work between the stabilizing seat 4 and the cutting table 1. At the same time, the pipe can be rotated according to the actual size of the pipe, so that the cutting knife 2 performs circular cutting on the pipe. At this time, since the contact wheel 7 can only rotate back and forth, it ensures that the pipe can rotate in a circular motion while ensuring the stability of the pipe.

[0036] It should be noted that the cutting table 1, cutting knife 2 and controller 3 are all devices or equipment existing in the prior art, or devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
