A second bracket 70 is fixedly provided on the side of the support frame 20 close to the ground rail 10, and the second bracket 70 is used to support the expansion sleeve 82.
[0021] Please refer to Figure 1 , first hoist the central shaft 80 onto the propulsion assembly 40. When the central shaft 80 is too long, the end can also be supported by the first bracket 50. Then place the expansion sleeve 82 on one side on the second bracket 70. The propulsion assembly 40 and the first bracket 50 move synchronously towards the support frame 20 through the moving assembly 60, pass one end of the central shaft 80 through the expansion sleeve 82 and contact the fixture 30, and use the fixture 30 to support and fix one end of the central shaft 80.
[0022] Please refer to Figure 2 , the propulsion assembly 40 and the first bracket 50 move away from the support frame 20, so that the propulsion assembly 40 and the first bracket 50 withdraw from the area of the central shaft 80. Then hoist the drum skin 81 above the propulsion assembly 40, and place the expansion sleeve 82 on the other side above the second bracket 70. The propulsion assembly 40 adjusts its height, adjusts the drum skin 81 and the central shaft 80 to the same axis, so that the propulsion assembly 40 moves towards the support frame 20 to start the shaft-passing work. At the same time, the second bracket 70 also moves synchronously. After the drum skin 81 completes the shaft-passing work, manually press the expansion sleeves 82 on the first bracket 50 and the second bracket 70 into both sides of the drum skin 81 for locking. After the assembly is completed, the fixture 30 releases one end of the central shaft 80, drives the central shaft 80 to move out of the fixture 30 through the propulsion assembly 40, hoist the assembled drum away, and complete the entire assembly operation.

One end of the diagonal brace 22 is fixedly connected to the base frame 21, and the clamp 30 is fixed to the upper end of the bracket 22, so as to ensure that after the clamp 30 clamps the central axis 80, the support frame 20 can remain stable to avoid the occurrence of the situation.
[0025] The clamp 30 includes a fixed frame 31, a clamping cylinder 32 and a first clamping block 33. The fixed frame 31 is fixed above the bracket 22, the first clamping block 33 is fixed in the middle of the fixed frame 31, the clamping cylinder 32 is arranged above the fixed frame 31, and the output shaft of the clamping cylinder 32 extends to the middle of the fixed frame 31 where a second clamping block 34 is provided. The first clamping block 33 and the second clamping block 34 are arranged opposite to each other.
[0026] When one end of the center shaft 80 is pushed between the first clamp block 33 and the second clamp block 34 through the moving assembly 60, the second clamp block 34 is pushed by the clamping cylinder 32 to move toward the side of the first clamp block 33, thereby clamping one end of the center shaft 80. The surface of the first clamp block 33 is a semi-cylindrical structure, and the surface of the second clamp block 34 is an inverted V-shaped structure, which can better adapt to center shafts 80 of different diameters and clamp the center shaft 80 between the first clamp block 33 and the second clamp block 34.
[0027] The first bracket 50 and the second bracket 70 have the same structure. The first bracket 50 includes a worm gear hoist 51 and a first bracket 52. The first bracket 52 is lifted up and down by the worm gear hoist 51. The first bracket 50 is fixedly connected to the support frame 20 through a support plate. The second bracket 70 is slidably connected to the ground rail 10 through a support seat 53. The moving component 60 is fixed to one side of the support seat 53.
[0028] Please refer to Figure 4 The propulsion assembly 40 includes a bottom plate 41, four groups of worm gear lifting seats 42, a lifting plate 43 and a second bracket 44. The bottom plate 41 is slidably connected to the ground rail 10. The four groups of worm gear lifting seats 42 correspond to the four corners of the bottom plate 41, and the worm gear lifting seats 42 are connected by a worm 45.

A guide rod 47 is provided under the lifting plate 43. The guide rod 47 is slidably connected to the bottom plate 41. The guide rod 47 is used to guide and limit the rise or fall of the lifting plate 43 to make it more stable.
[0030] Moreover, both the first support 52 and the second support 44 are V-shaped structures, which can better facilitate the center shaft 80 and the cylinder skin 81 to slide to the middle through the inclined surfaces of the first support 52 or the second support 44 after being placed above the first support 52 or the second support 44, achieving a better placement effect and avoiding rolling off from one side. And laser distance sensors are provided in the middle of the first support 52 and the second support 44. By detecting the distance from the center shaft 80 or the cylinder skin 81 to the middle of the first support 52 or the second support 44 with the laser distance sensors, the corresponding radius can be calculated, facilitating the heights of the first bracket 50 and the second bracket 70, so that the center shaft 80 and the cylinder skin 81 can be adjusted to the same horizontal line.

The rotating gear 62 is fixedly connected to the output shaft of the rotating motor 61, and the rotating gear 62 meshes with the rack 11. By driving the rotating gear 62 to rotate with the rotating motor 61, the rotating gear 62 can roll along the rack 11, achieving the purpose of moving left and right on the ground rail 10.
[0032] The utility model provides a large drum horizontal assembly device. First, hoist the center shaft onto the propulsion assembly. When the center shaft is too long, the end can also be supported by the first bracket. Then place the expansion sleeve on one side on the second bracket. The propulsion assembly and the first bracket move synchronously towards the support frame side through the moving assembly. Pass one end of the center shaft through the expansion sleeve and contact the fixture. After using the fixture to support and fix one end of the center shaft, the propulsion assembly and the first bracket move away from the support frame side, so that the propulsion assembly and the first bracket withdraw from the area of the center shaft. Then hoist the cylinder skin above the propulsion assembly, and place the expansion sleeve on the other side above the second bracket. Adjust the height of the propulsion assembly to adjust the cylinder skin and the center shaft to the same axis. Then the propulsion assembly moves towards the support frame side to start the shaft-passing work. At the same time, the second bracket also moves synchronously. After the cylinder skin completes the shaft-passing work, manually press the expansion sleeves on the first bracket and the second bracket into both sides of the cylinder skin to lock them. After the assembly is completed, the fixture releases one end of the center shaft, and the propulsion assembly drives the center shaft to move out of the fixture, and hoist the assembled drum away to complete the entire assembly operation.
