Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Refer to Figures 1-9, an oil and gas torch module hoisting device, including a mounting frame 8 and a mounting plate 19 arranged below the mounting frame 8. A sling mechanism is arranged between the mounting frame 8 and the mounting plate 19.

Two symmetrically arranged connecting plates 31 are arranged at the lower part of the mounting frame 8, and the two connecting plates 31 are fixedly connected with a torch barrel through a limiting mechanism. A first installation groove 24 is opened at the bottom end of the mounting frame 8. A second servo motor 25 is fixedly installed in the first installation groove 24, and a rotating gear 26 for controlling the connecting plate 31 to drive the torch barrel to deflect at an angle is fixedly installed at the output end of the second servo motor 25. Through the cooperation between the rotating gear 26 and the rack 23, the moving plate 22 drives the sliding block 21 and the connecting plate 31 to move synchronously, changing the installation angle of the torch barrel.

[0034] The sling mechanism includes a winding roller 15 rotatably installed on the moving block 11. A sling 17 is arranged on the outer wall of the winding roller 15. A rotating motor 16 for driving the winding roller 15 to wind the sling 17 is fixedly installed on the outer wall of the moving block 11. By rotating the rotating motor 16, the winding roller 15 winds the sling 17, changing the distance between the hook 18 fixedly installed at the bottom end of the sling 17 and the installation deck 36.

[0035] Two symmetrically arranged hanging rings 30 are fixedly installed on the mounting plate 19. Two hooks 18 are arranged at the bottom end of the sling 17, and both two hooks 18 are arranged inside the hanging rings 30, facilitating the hanging rings 30 to drive the mounting plate 19 to move synchronously.

[0036] The limiting mechanism includes a limiting frame 32 fixedly installed on the inner wall of the connecting plate 31 and having a U-shaped structure. Four electric push rods 34 are fixedly installed on the side wall of the limiting frame 32 and are equally spaced and circumferentially arranged. An installation table 35 is fixedly installed at the ends of the four electric push rods 34, and a limiting column 33 for limiting the torch barrel is fixedly installed on the installation table 35.

[0037] A circular hole penetrating the limiting frame 32 horizontally is opened on the limiting frame 32. The four electric push rods 34 are equally spaced around the circular hole, and the limiting column 33 is slidably arranged in the circular hole.

[0038] Two pairs of symmetrically arranged limiting blocks 12 are fixedly installed on the inner wall of the mounting frame 8, and the moving block 11 is slidably arranged in the limiting blocks 12. Two guide rails 14 are fixedly installed at the bottom end of the inner wall of the mounting frame 8. Two rollers 13 are rotatably installed on both side walls of the moving block 11, and the two rollers 13 are respectively slidably arranged in the two guide rails 14, changing the contact friction of the moving block 11 in the mounting frame 8 into rolling friction and reducing the friction loss between the moving block 11 and the mounting frame 8. A lead screw 10 is rotatably installed in the mounting frame 8. The moving block 11 is sleeved on the outer wall of the lead screw 10 through a thread. A first servo motor 9 for driving the lead screw 10 to rotate is fixedly installed at the end of the mounting frame 8.

[0039] On both sides of the mounting frame 8, two pairs of symmetrically arranged hoisting frames 1 are fixedly installed, and between each pair of hoisting frames 1, a plurality of equally spaced fixed frames 2 are fixedly installed. At the bottom ends of the two pairs of hoisting frames 1, bases 3 are fixedly installed. Through grooves 4 are opened in the bases 3. In the through grooves 4, a plurality of equally spaced and U-shaped rockers 5 are rotatably installed. On each of the plurality of rockers 5, a pulley 6 is rotatably installed. On the outer walls of the two bases 3, a plurality of drive motors 7 for driving the rockers 5 to rotate are fixedly installed. At the bottom ends of the two bases 3, an installation deck 36 is fixedly installed together. On the installation deck 36, a plurality of protective columns 37 are fixedly installed, and at the upper ends of the plurality of protective columns 37, a guardrail 38 is fixedly installed together.

At the bottom ends of the two sliding blocks 21, moving plates 22 are fixedly installed. And on the inner walls of the two moving plates 22, racks 23 meshing with the rotating gear 26 are fixedly installed. When the rotating gear 26 rotates, the racks 23 perform synchronous circular movement. The upper ends of the two connecting plates 31 are respectively fixedly connected to the bottom ends of the two moving plates 22. By driving the moving plates 22 to move through the racks 23, the connecting plates 31 perform circular movement, changing the installation angle of the flare stack.

[0041] When the holes on the flare arm of the flare stack are aligned with the holes on the flare stack, through the clamping and limiting of the fixing ring 29 by the limiting clamp 28, the rotation of the fixing ring 29 is avoided, ensuring the stability of the rotating gear 26. A fixing ring 29 is fixedly installed on the rotating gear 26. Between the first installation groove 24 and the sliding groove 20 at the bottom end of the mounting plate 19, a second installation groove 27 is opened, and in the second installation groove 27, four equally spaced limiting clamps 28 for limiting the fixing ring 29 are fixedly installed.

[0042] The functional principle of the present invention can be elaborated through the following operation methods:

[0043] By starting the drive motor 7, the output end of the drive motor 7 drives the rocker 5 to rotate, enabling the rocker 5 to drive the pulley 6 to perform eccentric rotation, making the bottom end of the pulley 6 contact and support the upper surface of the installation deck 36, changing the contact friction between the base 3 and the installation deck 36 into rolling friction, facilitating the movement of the base 3 on the installation deck 36, avoiding the problem of difficult movement of traditional lifting tools, and making the lifting tool more practical and widely applicable;

[0044] Start the rotation of the driving motor 16 to control the rotation of the winding roller 15, so that the sling 17 drives the ring 30 hoisted at the bottom of the hook 18 to move vertically. After the mounting plate 19 fixedly installed at the bottom end of the ring 30 reaches the appropriate position, control the rotation of the rotating gear 26 through the second servo motor 25, so that the racks 23 meshed with both ends of the rotating gear 26 drive the moving plate 22 to move in a circular motion, change the installation angle of the flare stack between the two connecting plates 31, and cooperate with the rotation of the first servo motor 9 to make the lead screw 10 rotate, so that the moving block 11 slides horizontally in the mounting bracket 8 to change the installation position of the flare stack at the bottom end of the mounting plate 19. When the installation hole positions are aligned, clamp the fixed ring 29 fixedly installed on the rotating gear 26 through the limit clamp 28 to prevent the angle of the rotating gear 26 from deflecting, so that the hole positions of the flare stack and the hole positions on the flare arm are completely aligned, facilitating the installation of the flare stack and effectively improving the installation efficiency of the flare stack;

[0045] Control the telescoping of the four electric push rods 34, so that the mounting table 35 drives the limit posts 33 to slide in the circular holes, so that the limit posts 33 slide out of the circular holes and release the limit on the flare stack, and there is no need for manual operation to release the limit, making the automation degree of the equipment higher.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
