However, this method of securing the drum requires multi-directional winding, which is time-consuming and labor-intensive. Moreover, the binding and tightening of the ropes around the drum is often not secure enough, and the drum is prone to slipping when suspended by the lifting equipment, posing a risk of the drum falling during suspension.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5A combined lifting device includes several support frames 1, connecting frames 2, and two fixed frames 5. The support frames 1 are evenly distributed in a straight line. A connecting frame 2 is provided between each two adjacent support frames 1, and the adjacent support frames 1 are fixedly connected by the connecting frame 2. A side clamping mechanism 3 is provided on the support frame 1 for clamping the side of the boiler drum. The two fixed frames 5 are fixedly provided at the left and right ends of the lifting device. An end clamping mechanism 6 is provided on the top of the fixed frame 5 for clamping the end of the boiler drum. Fixed columns 7 are fixedly provided at the front and rear ends of the top of the fixed frame 5, and the end clamping mechanism 6 is located between the two fixed columns 7 on the top of the fixed frame 5. A pull ring 8 is provided on the top of the fixed column 7. A lifting rope is wound on the pull ring 8, and the top of the lifting rope on the four pull rings 8 is fixedly connected to a ring-shaped lifting buckle. The crane lifts the lifting device through the ring-shaped lifting buckle.

[0028] The side clamping mechanism 3 includes a toothed plate 301, a connecting rod 303, and a clamping plate 304. A storage cavity 101 is provided inside the support frame 1. Two toothed plates 301 are installed inside the storage cavity 101, and the two toothed plates 301 are slidably connected to the top and bottom of the storage cavity 101, respectively. A gear 302 is provided between the two toothed plates 301, and the gear 302 meshes with the two toothed plates 301. The rotation of the gear 302 drives the two toothed plates 301 to move towards each other. The two toothed plates 301 pass through both ends of the support frame 1. A connecting rod 303 is fixedly installed on the top of each plate 301. A sliding groove 102 is opened on the top of the support frame 1, and the connecting rod 303 and the sliding groove 102 are slidably connected. The sliding groove 102 limits the sliding position of the connecting rod 303. A clamping plate 304 is fixedly installed on the opposite surface of the two connecting rods 303, and the two clamping plates 304 are at the same height. An anti-slip layer is provided on the opposite surface of the two clamping plates 304, and the anti-slip layer is an anti-slip rubber pad. The high friction of the anti-slip rubber pad further improves the stability of the boiler drum on the hanger.

[0029] Among them, several support frames 1 are pierced by rotating shafts 9, and the rotating shafts 9 and support frames 1 are rotatably connected. Gears 302 are fixedly mounted on the rotating shafts 9. One end of the rotating shaft 9 is provided with a fixing mechanism 4 for fixing the rotational position of the rotating shaft 9. The fixing mechanism 4 includes a fixing platform 401, which is fixedly located on the right side of the rightmost support frame 1. The rotating shaft 9 passes through the fixing platform 401 and is rotatably connected to the fixing platform 401 through a bearing. A limiting plate 402 is provided on the side of the fixing platform 401 away from the support frame 1, and the limiting plate 402 is fixedly mounted on the rotating shaft. On the 9, the fixed platform 401 has several threaded holes 403 on the side away from the support frame 1, and the several threaded holes 403 are evenly distributed around the rotating shaft 9. The limiting plate 402 is provided with screws 404, and the screws 404 are threadedly connected to the fixed platform 401 through the threaded holes 403. By turning the screws 404 into the threaded holes 403, the position of the limiting plate 402 is limited, and the position of the rotating shaft 9 is fixed by the limiting plate 402. By limiting the rotation position of the rotating shaft 9, the side clamping strength of the clamping plate 304 is ensured.

[0030] The end clamping mechanism 6 includes a fixed rod 601 and a clamping claw 603. The fixed rod 601 is fixedly mounted on the top of the fixed frame 5. A horizontal threaded shaft 602 is threaded onto the fixed rod 601 and passes through the fixed rod 601. The clamping claw 603 is rotatably mounted on the end of the threaded shaft 602 near the support frame 1, and a handle 604 is fixedly mounted on the end of the threaded shaft 602 away from the support frame 1. By rotating the handle 604, the threaded shaft 602 is rotated, thereby driving the clamping claw 603 to move, making the control of the clamping claw 603 more convenient and quick. The threaded assembly of the threaded shaft 602 and the fixed rod 601 improves the end clamping strength of the clamping claw 603.

[0031] Working principle: When using this lifting device to suspend and install the boiler drum, first place the boiler drum between two clamping claws 603, then rotate and remove the screw 404, then rotate the rotating shaft 9, which drives the gear 302 to rotate, and the gear 302 drives the two toothed plates 301 on the support frame 1 to slide towards each other, and then the two toothed plates 301 drive the connecting rod 303 to slide towards each other, thereby clamping the side of the boiler drum through the clamping plate 304. Then, the screw 404 is turned into the threaded hole 403, thereby fixing the rotation of the rotating shaft 9 through the limiting plate 402. Then, rotate the threaded shaft 602, and use the threaded assembly of the threaded shaft 602 and the fixing rod 601 to drive the clamping claws 603 to move and clamp the end of the boiler drum. The crane is then engaged in the ring-shaped lifting buckle of the lifting device, and then the boiler drum is suspended.
