Description

Technical Field

[0001] This utility model relates to the field of oil and gas blasting technology; more specifically, it relates to an emergency blasting cutter for oil and gas pipeline rescue. Background Technology

[0002] The field of oil and gas blasting technology refers to a comprehensive technical field that utilizes blasting energy and related engineering techniques to carry out operations such as rock breaking, pipeline cutting, wellbore cleaning, and obstacle removal in the exploration, development, transportation, and emergency rescue of oil and gas resources. Oil and gas pipeline emergency blasting cutters are commonly used in the field of oil and gas blasting technology. They are emergency cutting devices specifically designed for oil and gas pipeline emergency rescue operations. They use blasting energy to quickly and accurately cut off pipelines to deal with sudden accidents such as pipeline leaks, fires, and explosions, prevent the accidents from escalating, and ensure the safety of personnel and the environment.

[0003] Currently, existing blasting cutters are cumbersome to operate when fixing the equipment to oil and gas pipelines, making emergency handling inconvenient and potentially delaying rescue efforts or failing to achieve the desired cutting effect, thus reducing the equipment's emergency response performance. Furthermore, the positioning of existing blasting cutters is typically slow, requiring operators to remain in hazardous environments for extended periods, thereby reducing the equipment's safety and practicality. Therefore, there is an urgent need for an emergency blasting cutter for oil and gas pipeline rescue to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an emergency blasting cutter for oil and gas pipeline rescue, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an emergency blasting cutter for oil and gas pipeline rescue, including a first positioning plate:

[0006] The upper end of the first positioning plate is hinged to the second positioning plate. Bolts are threaded to both sides of the upper end of the first positioning plate. Magnetic suction plates are provided on both sides of the first and second positioning plates. Movable grooves are opened at the upper ends of the first and second positioning plates. A blasting box is slidably engaged inside the movable groove. Both ends of the blasting box are hinged to hinge blocks, and magnetic suction blocks are fixed to the inner walls of the hinge blocks.

[0007] Preferably, threaded grooves are provided on both sides of the upper end of the second positioning plate, and the surface of the threaded grooves is adapted to the surface of the bolt. When the positions of the threaded grooves and the bolts correspond, the positions of the first positioning plate and the second positioning plate can be fixed by rotating the bolts, thereby improving the convenience of the equipment.

[0008] Preferably, both the first positioning plate and the second positioning plate are arc-shaped. With the above-mentioned arrangement, the equipment can fit more closely to the surface of the oil and gas pipeline, thereby enabling the equipment to be positioned more quickly.

[0009] Preferably, the upper end of the blasting box is threaded with a top cover. Before the equipment is used, the explosive can be placed inside the blasting box, and then the top cover is fixed by the threaded connection.

[0010] Preferably, the lower end of the blasting box is provided with a slider, and the slider is arc-shaped. The surface of the slider is adapted to the surface of the moving groove. Through the use of the arc shape, the position of the blasting box can be moved more quickly.

[0011] Preferably, the position of the magnetic block corresponds to the surface position of the magnetic plate, and the position of the blasting box can be fixed through the above operation.

[0012] The technical effects and advantages of this utility model are as follows: This utility model moves the first positioning plate so that its lower end surface is in contact with the surface of the oil and gas pipeline, and then rotates the second positioning plate. When the lower end surface of the second positioning plate is in contact with the surface of the oil and gas pipeline, the positions of the first positioning plate and the second positioning plate can be fixed by rotating the bolts, thereby fixing the position of the equipment and the oil and gas pipeline. This operation is relatively simple and facilitates emergency handling, which improves the performance of the equipment and its emergency response performance to a certain extent.

[0013] By moving the position of the blasting box on the surface of the moving slot, when the blasting box corresponds to the blasting point, two sets of hinge blocks can be rotated so that the surface of the magnetic block is in contact with the surface of the magnetic plate, thereby fixing the position of the blasting box. This installation method is relatively quick, thereby reducing the operator's dwell time and improving the safety and practicality of the equipment. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The oil and gas blasting involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] like Figures 1 to 3 As shown, this embodiment proposes an emergency blasting cutter for oil and gas pipeline rescue, including a first positioning plate 1, a second positioning plate 2 is hinged to the upper end of the first positioning plate 1, bolts 3 are threaded to both sides of the upper end of the first positioning plate 1, and threaded grooves are opened on both sides of the upper end of the second positioning plate 2, and the surface of the threaded grooves is adapted to the surface of the bolts 3. Both the first positioning plate 1 and the second positioning plate 2 are arc-shaped.

[0022] In this embodiment, the surface of the oil and gas pipeline can be fitted together by the cooperation of the first positioning plate 1 and the second positioning plate 2. Then, the bolt 3 is rotated to fix both of them to the position of the oil and gas pipeline at the same time. The above operation is relatively simple, which can reduce the installation time of the workers and thus improve its safety.

[0023] Example 2

[0024] like Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: magnetic suction plates 4 are provided on both sides of the first positioning plate 1 and the second positioning plate 2, and a moving groove 5 is provided at the upper end of the first positioning plate 1 and the second positioning plate 2, and a blasting box 6 is slidably engaged inside the moving groove 5. A hinge block 7 is hinged to both ends of the blasting box 6, and a magnetic suction block 8 is fixed to the inner wall of the hinge block 7. A top cover is threaded to the upper end of the blasting box 6, and a slider is provided at the lower end of the blasting box 6. The slider is arc-shaped, and the surface of the slider is adapted to the surface of the moving groove 5. The position of the magnetic suction block 8 corresponds to the surface position of the magnetic suction plate 4.

[0025] In this embodiment, by using the magnetic suction plate 4 and the magnetic suction block 8 together, when the position of the blasting box 6 is moved appropriately, the magnetic suction block 8 can be rotated by rotating the hinge block 7, thereby making the surface of the magnetic suction block 8 fit against the surface of the magnetic suction plate 4, and the strong attraction between the two can fix the position of the blasting box 6. By using the top cover together, when the explosives and blasting equipment are placed inside the blasting box 6, the position of the top cover and the blasting box 6 can be fixed by threads, thereby preventing the explosives from shifting or falling, thus improving the success rate of blasting. By using the slider together, the blasting box 6 can be moved inside the moving slot 5 according to the actual situation, thereby improving the convenience and applicability of the equipment.

[0026] Working principle: When using the equipment, firstly, the lower surface of the first positioning plate 1 is brought into contact with the surface of the oil and gas pipeline. Then, the second positioning plate 2 is rotated. When the lower surface of the second positioning plate 2 is in contact with the surface of the oil and gas pipeline, the positions of the first positioning plate 1 and the second positioning plate 2 are fixed by rotating the bolt 3, thereby fixing the position of the equipment and the oil and gas pipeline. Next, the explosive to be used for blasting is placed inside the blasting box 6, and the top cover of the blasting box 6 is fixed by threads. Then, the blasting box 6 is moved to the blasting point, and then the two sets of hinge blocks are rotated. 7. This allows the surface of the magnetic block 8 to adhere to the surface of the magnetic plate 4, thereby fixing the position of the blasting box 6. Finally, the equipment can be activated to blast the oil and gas pipeline. In this application, the shock wave and high-pressure gas generated by the explosion of the explosive are directly applied to the oil and gas pipeline, causing the pipeline to break under the strong external force. When the explosive explodes, high-temperature and high-pressure gas is generated in a very short time. This gas expands rapidly to form a shock wave. The shock wave acts on the pipeline wall, causing the pipeline material to deform, stretch, and eventually break. The above is the entire working principle of this utility model.

[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
