[0018] The specific embodiments of the utility model are further described in detail below. Figures 1-6 The specific embodiments of the utility model are further described in detail below.

[0019] The technical scheme solved by the embodiment is that, in use, the hanging assembly 8 can be matched with the cylinder body 1 of the pressure container, specifically matched with the connecting hole 3 of the flange 2 on the cylinder body 1, thereby achieving connection of the cylinder body 1. The three sets of hanging assemblies 8 are evenly arranged and matched with the connecting holes 3 on the flange 2, ensuring the safety coefficient of the connection, so as to facilitate safe hoisting operation. The structure is simple, convenient to use, and highly practical. In use, the jib 13 is first separated from the guide cylinder 11, then the jib 13 is inserted into the connecting hole 3 from bottom to top, so that the flange 2 is abutted by the baffle disc 17, then the jib 13 is inserted into the guide cylinder 11 and matched with the limiting block 12 and the limiting groove 14, thereby limiting the jib 13 in the installation cylinder and effectively preventing disengagement, thereby achieving the function of the hanging assembly 8. The operation is simple, and the connection is safe.

[0020] In the embodiment, to ensure the stability of hoisting, the three sets of hanging assemblies 8 should be evenly arranged on the circumference of the flange 2 and matched with the corresponding connecting holes 3, as shown in the drawings. Figure 1

[0021] Before use, the jib 13 is separated from the guide cylinder 11. Specifically, the jib 13 is slid upward relative to the guide cylinder 11, which causes the limiting block 12 to disengage from the limiting groove 14, until the limiting block 12 completely disengages from the limiting groove 14 and enters the ring groove 15. Then the jib 13 is rotated, so that the limiting block 12 rotates around the ring groove 15, until the limiting block 12 is matched with the guide groove 16. The matching of the limiting block 12 and the guide groove 16 facilitates the downward sliding of the jib 13 along the guide cylinder 11, thereby separating the jib 13 from the guide cylinder 11.

[0022] After the jib 13 is separated from the guide cylinder 11, the cylinder body 1 can be connected. Specifically, the jib 13 is inserted into the connecting hole 3 from bottom to top, then the guide groove 16 on the jib 13 is matched with the limiting block 12 on the guide cylinder 11, thereby inserting the jib 13 into the guide cylinder 11. With the insertion of the jib 13, the limiting block 12 will reach the position of the ring groove 15 along the guide groove 16. At this time, the jib 13 is rotated, so that the limiting block 12 rotates relative to the ring groove 15, until the limiting block 12 is matched with the limiting groove 14 on the jib 13. At this time, the jib 13 is adjusted, so that the limiting block 12 completely enters the limiting groove 14, thereby completing the connection of the cylinder body 1. The operation is simple, then the lifting eye 5 on the connecting disc 4 is connected with the hook of the external hoisting equipment, thereby completing the hoisting operation.

[0023] ​In the third embodiment, the connecting plate 4 is connected with a steel strand 7 through the upper mounting ring 6, the steel strand 7 is connected with a hanging device through the lower mounting ring 9, the hanging device is connected with the connecting hole 3 on the flange 2, and then the external crane equipment is convenient for hoisting. The guide cylinder 11 is rotatably connected with the lower mounting ring 9 through the mounting disc 10, and the adjustment of the corresponding parts when the boom 13 cooperates with the guide cylinder 11 is more convenient. Of course, the fixed connection can also achieve the purpose of the application. The gasket 18 arranged on the blocking disc 17 can increase the friction force of the contact surface, and ensure stable hoisting.
