The bottom of the main lifting beam is provided with a first groove, and an upper slider that is slidably connected in the first groove and cooperates with the first bolt group is provided in the first groove. The bottom surface of the main lifting beam is connected with a stop bar to prevent the upper slider from falling off.

[0008] Furthermore, the sliding seat has a second boss on the side near the inner wall of the first flange, and the inner side of the second boss has an arc-shaped structure and abuts against the inner wall of the first flange.

[0009] Furthermore, the tailing device assembly includes: a support assembly, a second shackle, and a second lower sling; A second flange is connected to the bottom of the cylinder; One end of the lifting seat assembly is detachably connected to the second flange, and the other end is detachably connected to one end of the second lower sling via the second shackle.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example

[0020] Reference Figure 1-10 In this embodiment, a convenient and adjustable universal lifting tool includes: One end of the main lifting assembly is detachably connected to the top of the cylinder 19, and the other end is connected to the crane hook.

[0021] One end of the tailing lifting device assembly is detachably connected to the bottom of the cylinder 19, and the other end is connected to the crane hook.

[0022] In this embodiment, the main lifting tool assembly and the tailing lifting tool assembly are installed above and below the cylinder, respectively. By eliminating the main load-bearing role of bolts, the core risk of insufficient bolt strength is solved, resulting in positive effects such as reducing the number of bolts installed, simplifying the installation process, and improving lifting efficiency.

[0023] Reference Figure 2 It should be specifically noted that, in this embodiment, the main lifting device assembly includes: a main lifting beam 1, a sliding seat 4, a first upper lifting cable 3, a pulley 5, a first bolt group 14, and two first shackles 2; the top of the cylinder 19 is connected to a first flange. One end of the main lifting beam 1 has a lifting seat, the top of which is connected to one of the first shackles 2, and the bottom of the lifting seat is detachably connected to the first flange via the first bolt group 14.

[0024] Specifically, the sliding seat 4 is located at the end of the main lifting beam away from the lifting base, and has an opening in the middle. One end of the main lifting beam passes through the opening and is slidably connected to it. The sliding seat 4 can slide along the main lifting beam 1 to adjust its position. The top of the sliding seat 4 is connected to another first shackle 2, the middle of the sliding seat 4 is slidably connected to the main lifting beam 1, and the bottom of the sliding seat 4 is detachably connected to the first flange through the first bolt group 14. By adjusting the position of the sliding seat 4, the installation diameter of the main lifting assembly can be steplessly adjusted.

[0025] The lifting seat and sliding seat are located on both sides of the main lifting beam 1. A first groove is provided on the side of both near the first flange. An upper sliding block 12, which mates with the first bolt assembly 14, is slidably connected within the first groove. A stop bar 13 is connected to the bottom surface of the main lifting beam 1 to prevent the upper sliding block 12 from falling off. Specifically, the upper sliding block 12 can slide and adjust its spacing within the first groove. The upper sliding block 12 has an elongated hole into which the first bolt assembly 14 is installed. This assembly method can flexibly adapt to various first flange connection interfaces. The stop bar 13 fixes the upper sliding block 12 within the first groove on the main lifting beam 1, preventing the upper sliding block 12 from falling off.

[0026] Specifically, the lifting seat has a first concave boss 20, the inner side of which has an arc-shaped structure and contacts the outer wall of the first flange on the cylinder to bear force. The sliding seat 4 has a second convex boss 21, the outer side of which has an arc-shaped structure and contacts the upper part of the inner wall of the first flange on the cylinder to bear force. This changes the load transmission path of the lifting device, eliminates the main force-bearing role of the bolt, and solves the core risk of insufficient bolt strength.

[0027] Both ends of the first upper sling 3 are simultaneously threaded onto two first shackles 2, and the middle of the first upper sling 3 is slidably connected to the pulley 5. The pulley is provided to balance the first upper sling 3 when the cylinder is tilted. One end of the second upper sling 6 is threaded and connected to the top of the pulley 5, and the other end is connected to the crane hook. Specifically, the sliding seat 4 can slide and adjust its position on the main lifting beam 1. Both the main lifting beam 1 and the sliding seat 4 are equipped with ear plates connected to the first shackles 2. The first upper sling 3 passes through the pulley below the pulley 5 in the middle and is connected to the first shackles 2 on both sides. The upper shaft of the pulley 5 is connected to the second upper sling 6. When the cylinder rotates and tilts, the pulley below the pulley 5 rotates to adjust the length of the first upper sling 3 on both sides, ensuring the balance of the beam.

[0028] Reference Figure 4 It should be further explained that, in this embodiment, the tailing lifting device assembly includes: a lifting base assembly, a second shackle 9, and a second lower sling 10; a second flange is connected to the bottom of the cylinder 19. One end of the lifting base assembly is detachably connected to the second flange, and the other end is detachably connected to one end of the second lower sling 10 via the second shackle 9. The other end of the second lower sling 10 is connected to the crane hook.

[0029] Specifically, the lifting bracket assembly includes: a lower lifting bracket 7 and a first lower lifting cable 8. One end of the lower lifting bracket 7 is detachably connected to the second flange via a second bolt group 18, and the other end is connected to one end of the first lower lifting cable 8 via a first shackle 2. The other end of the first lower lifting cable 8 is connected to a second shackle 9.

[0030] The lifting bracket assembly consists of multiple sets, symmetrically connected to the lower center of the second flange. In this embodiment, there are two sets of lifting bracket assemblies, with two lower lifting brackets 7 symmetrically installed at 45 degrees below the cylindrical flange. The lower lifting brackets 7 are connected to the first lower lifting cable 8, and the other end of each of the two first lower lifting cables 8 is connected to a second shackle 9. The other side of the second shackle 9 is connected to a second lower lifting cable 10, and the other end of the second lower lifting cable 10 is connected to the crane hook.

[0031] A pad 11 is detachably connected to one end of the second flange near the second lower sling 10. The pad 11 is slidably connected to the second lower sling 10. The pad 11 is bolted to the top of the second flange. The second lower sling 10 should be locked in the groove of the pad 11 to prevent the second lower sling 10 from being cut by the cylinder flange during the lifting and turning process.

[0032] Specifically, in this embodiment, the lower lifting seat 7 includes a lifting seat body 15. A second groove is provided at the bottom of the lifting seat body 15, and a lower slider 16 is slidably connected within the second groove. The lower slider 16 is connected to a second bolt assembly 18. A baffle 17 is connected to the bottom surface of the lifting seat body 15 to prevent the lower slider 16 from falling off. Specifically, the lifting seat body 15 has an arc-shaped boss 20 that contacts and bears force with the outer wall of the second flange below the cylinder. The lifting seat body 15 has a second groove for installing the lower slider 16, which can slide within the second groove. The lower slider 16 has an elongated hole for installing the second bolt assembly 18. The baffle 17 fixes the lower slider 16 in the second groove on the lifting seat body 15, and the second bolt assembly 18 fixes the lifting seat body 15 to the second flange hole, preventing the lifting device from falling off.

[0033] This invention changes the force mechanism and load transfer path of the lifting equipment during the hoisting of cylindrical structures. It eliminates the primary force-bearing role of bolts and utilizes the boss structure in the main lifting equipment assembly and the tailing lifting equipment assembly to transfer force with the flange wall of the cylindrical structure. This reduces the number of bolts required, improves installation convenience, and makes the lifting equipment installation faster, simpler, and less demanding on construction personnel. Furthermore, the invention utilizes the boss of the lifting equipment for more reliable force bearing, fundamentally eliminating the risk of bolt failure due to insufficient strength or preload of the connecting bolts. Example

[0034] This embodiment provides a lifting method for a convenient and adjustable universal cylindrical lifting tool, which is the lifting method for the convenient and adjustable universal cylindrical lifting tool provided in Embodiment 1, as follows: Step 1: Install the sliding seat 4 on one side of the main lifting beam 1. Adjust the sliding seat 4 to a suitable position on the main lifting beam 1. Adjust the upper slider 12 to align with the mounting hole. Use the first bolt group 14 to fix the main lifting beam 1 and the sliding seat 4 above the first flange on the top of the cylinder. Connect the ear plates on the main lifting beam 1 and the sliding seat 4 to the first shackle 2. After passing through the middle of the first upper lifting cable 3 around the pulley below the trolley 5, connect both sides to the first shackle 2. Connect the upper lifting shaft of the trolley 5 to the second upper lifting cable 6. Connect the other end of the second upper lifting cable 6 to the crane hook.

[0035] Step 2: Install the two lower lifting seats 7 symmetrically at a certain angle below the second flange at the bottom of the cylinder using the second bolt group 18. Fix the gasket 11 to the middle position above the cylinder with bolts. The lower lifting seats 7 are connected to the first lower lifting slings 8. The other end of each of the two first lower lifting slings 8 is connected to the second shackle 9. The other side of the second shackle 9 is connected to the second lower lifting sling 10. The other end of the second lower lifting sling 10 is connected to the crane hook.

[0036] Step 3: The crane hook slowly lifts the cylinder, ensuring the arc-shaped protrusions 20 on the main lifting beam 1 and sliding seat 4 fully contact the flange wall on the cylinder. The pulleys below the trolley 5 rotate to adjust the lengths of both sides of the first upper lifting cable 3, ensuring the beam is balanced. The arc-shaped protrusions 20 on the lower lifting seat 7 fully contact the outer wall of the flange below the cylinder; the second lower lifting cable 10 should be secured in the groove of the pad block 11 to prevent damage to the second lower lifting cable 10.

[0037] Step 4: After the cylinder is flipped over, first disassemble the second bolt group 18 of the lower lifting seat 7 and its connected lifting slings in sequence. After the cylinder is hoisted, remove the connection between the main lifting beam 1 and the sliding seat 4, and lift the entire lifting device back to the ground. Then, disassemble the connected lifting slings in sequence.

[0038] This invention employs a lifting method in which the main lifting tool assembly and the tailing lifting tool assembly are in contact with the flange wall of the cylinder, thereby changing the load transfer path of the lifting tools, eliminating the main load-bearing role of bolts, solving the core risk of insufficient bolt strength, and bringing positive effects such as reducing the number of bolts installed, simplifying the installation process, and improving lifting efficiency.

[0039] By adjusting the positions of the upper and lower sliders, this invention can be adapted to various cylinder diameter interfaces, improving the versatility and convenience of the lifting tool and saving lifting costs.
