[0002] Special-shaped diamond wire cutting equipment is used for rapid and precise cutting of well control pipes in narrow working spaces during emergency rescue of blowouts on offshore drilling platforms.

[0003] During assembly of existing diamond wire saw equipment, the actuator must be placed in the appropriate position in front of the wellhead. When the actuator is positioned on an offshore platform, hot welding is required to secure two bolts in place. Then, two fixing bolts are tightened to secure the equipment. This prevents the actuator from being pulled down by the reaction force of the wire saw, potentially damaging the equipment.

[0004] The need for welding makes the installation and disassembly process inconvenient. Traditional welding and fixing methods often produce high-temperature metal chips or other impurities, as well as gases such as carbon dioxide, causing air pollution. At the same time, traditional hot work welding methods may cause flammable gas leakage and even explosion risks during on-site rescue. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 3 As shown, a magnetic fixing device for small and medium-sized emergency cutting equipment includes a shell 1, a clamping component arranged on the top of the shell 1, a support base 4 and a magnetic attraction component arranged on the bottom of the shell 1.

[0025] The clamping assembly includes a fixed clamping plate 2 fixedly connected to the top surface of the shell 1 and a movable clamping plate 3 movably connected to the top surface of the shell 1 through an adjustment assembly;

[0026] The adjustment assembly includes a threaded rod 10 passing through the movable splint 3 and a screw handle 11 arranged at the free end of the threaded rod 10. The movable splint 3 and the threaded rod 10 are arranged in the same manner as the screw rod and the screw nut. Rotating the screw handle 11 drives the threaded rod 10 to rotate, and then drives the movable splint 3 to move along the axis of the threaded rod 10.

[0027] In this embodiment, in order to allow the threaded rod to move, a limiting groove is formed on the top of the housing 1, and the bottom of the movable splint 3 is placed in the limiting groove.

[0028] The magnetic attraction assembly includes a clamping plate magnet 8 arranged on the opposite sides of the fixed clamping plate 2 and the movable clamping plate 3, a plurality of permanent magnets 12 arranged in the support base 4, and a permanent magnet control assembly.

[0029] The permanent magnet control assembly includes a connecting rod 13, a central rotating handle 5 and a rotating pair. The two connecting rods 13 are arranged in parallel and are connected to the axes of all permanent magnets 12; the rotating pair includes a main gear 6 arranged in the shell 1, a slave gear 15 arranged on the permanent magnet 12 at the center position, and a rack 7. The two ends of the rack 7 are respectively engaged with the main gear 6 and the slave gear 15; the central rotating handle 5 is arranged outside the shell 1, and one end extends into the shell 1 and is fixed to the center of the main gear 6. Rotating the central rotating handle 5 drives the main gear 6 to rotate, and the slave gear 15 is rotated through the rack 7, thereby realizing the rotation of the permanent magnet 12 at the center position fixed to the slave gear 15. Since all permanent magnets 12 are connected by two connecting rods, when the permanent magnet 12 at the center position rotates, the remaining permanent magnets rotate synchronously to achieve magnetic force adjustment.

[0030] In this embodiment, in order to facilitate the installation of the clamping plate magnet 8, mounting grooves are formed at corresponding positions of the fixed clamping plate 2 and the movable clamping plate 3.

[0031] In this embodiment, in order to effectively protect the device, a soft pad 9 is provided on the outside of the clamping plate magnet 8. The soft pad 9 is made of a soft and plastic material such as sponge;

[0032] In this embodiment, in order to facilitate the installation and stable rotation of the permanent magnet, a plurality of circular rotation slots are provided in the support base 4, and the permanent magnet 12 is provided in the rotation slots.

[0033] In this embodiment, for the installation of various components, the connecting rod 13 and the slave gear 15 are located on opposite sides of the central permanent magnet 12. Preferably, the connecting rod 13 is arranged on the front side of the central permanent magnet 12, and the slave gear 15 is arranged on the back side.

[0034] In this embodiment, in order to improve the stability of the entire device, a rubber pad 14 is provided at the bottom of the support base 4 to increase the friction of the bottom of the device.

[0035] The equipment chassis 16 is arranged between the fixed clamping plate 2 and the movable clamping plate 3 .

[0036] The use method of this utility model:

[0037] During use, the screw handle 11 is rotated to make the threaded rod 10 drive the movable splint 3 to move, thereby increasing the gap between the fixed splint 2 and the movable splint 3 so that the device can be easily installed on the device chassis 16; after the installation is completed, the screw handle 11 is rotated in the opposite direction again so that the movable splint 3 and the fixed splint 2 clamp the device chassis 16, the soft pad 9 can increase the friction force, and the splint magnet 8 can be adsorbed on the device chassis 16 to make the clamping more secure.

[0038] During operation, the central handle 5 rotates, causing the main gear 6 connected to it to transmit stress along the rack 7 to the slave gear 15 connected to the central permanent magnet 12. This in turn causes the connecting rod 13 to rotate all the permanent magnets 12 in all the support blocks 4. When all the permanent magnets 12 are rotated to a horizontal position, the magnetic force is maximized, effectively securing the device to the metal surface. If there are any uneven rust stains on the metal surface to which the device is fixed, the rubber pad 14 will automatically fill them and increase the friction of the fixing device.

[0039] Compared with the traditional welding fixation method, this utility model has the following advantages:

[0040] In terms of safety and environmental protection: The magnetic fixing method avoids the risk of flammable gas leakage and explosion that may be caused by the traditional hot work welding fixing method during on-site rescue, greatly reduces the risk of cutting pipe strings for offshore platform clearance, avoids high-temperature metal flying chips or other impurities generated by welding operations, and the generation of gases such as carbon dioxide, without generating any pollutants, and is green and environmentally friendly.

[0041] In terms of portability: it is flexible to assemble and disassemble, highly portable, and reusable, which improves efficiency and reduces the labor intensity of operators; at the same time, the magnetic fixing device does not require punching or cutting objects, which can avoid damage or changes to the objects, and the size of the magnetic force can be adjusted through the central handle and other control components, making the magnetic fixing device suitable for objects of different sizes and weights.

[0042] In terms of stability and reliability: by placing multiple magnets in parallel, the device has a stronger magnetic adsorption force and adsorption range. At the same time, the evenly placed magnets can also ensure that the adsorption direction is uniform and firm. If there are uneven rust stains on the metal surface where the device is fixed, the rubber pad can automatically fill the gap and increase the friction of the fixing device.
