In the process of auxiliary lifting and assembly, the state of the present lifting device is changed from the state in Figure 1 to the state in Figure 6 .

[0027] Please refer to Figure 1 and Figure 2 , it can be seen that:

[0028] The hanging device comprises two opposite steel cables 1, and a cable supporting assembly is installed between the two steel cables 1 to support the middle part of the two steel cables 1 at a certain distance. By using the cable supporting assembly to support the two steel cables 1, the problem of interference between the steel cables 1 and the lifted object during lifting and assembly is effectively avoided, and the stability and safety of the lifting and assembly process are ensured.

[0029] In this embodiment, a lifting lug is arranged at the upper end and the lower end of each of the two steel cables 1. The lifting lug at the upper end is used to connect with the crane equipment, and the lifting lug at the lower end is used to connect with the bearing frame device 5.

[0030] In this embodiment, the cable supporting assembly comprises a support crossbeam 4, and an upper end inwardly inclined support inner plate 2 is welded and installed at both ends of the support crossbeam 4.

The lifting lug 6 includes a lug plate, and a connection hole is provided at the upper end and the lower end of the lug plate. The connecting bolt 7 penetrates the adjustment connection hole 54 and the connection hole at the lower end of the lifting lug 6, and the lifting ring at the lower end of the steel cable 1 is connected to the connection hole at the upper end of the lifting lug 6. When the lifting point position needs to be adjusted, the connecting bolt 7 is disassembled and the lifting lug 6 is installed at the position of another adjustment connection hole 54.

[0037] A first support 57 is installed inside the upper arm of the cross-shaped support 51, and a second support 58 is installed inside the lower arm of the cross-shaped support 51. A first adapter seat 55 is installed at the front end of the first support 57 through a hinge shaft 59, and a second adapter seat 56 is installed at the front end of the second support 58 through a hinge shaft 59. Among them, the first support 57 and the second support 58 both play a supporting role, and the first adapter seat 55 and the second adapter seat 56 are used to install the hoisted object, that is, the rocket cabin section.

[0038] In this embodiment, the first adapter 55 includes a T-shaped first adapter plate and a U-shaped first adapter base. The middle part of the first adapter plate is welded and fixedly connected to the front end of the first adapter base. Connection holes are provided at both ends of the first adapter plate. The front end of the first support 57 is located in the groove of the first adapter base and is hinged by the hinge shaft 59.

[0039] In this embodiment, the second adapter 56 includes a T-shaped second adapter plate and a U-shaped second adapter base.

The second support 58 is a T-shaped shaft seat with a diameter at its outer end greater than that at its inner end. The outer end of the second support 58 is welded and fixed to the lower arm of the cross-shaped bracket 51.

[0042] like Figure 5 As shown, since the first adapter 55 is hinged to the first support 57 and the second adapter 56 is hinged to the second support 58, the load-bearing frame device 5 can be connected to the suspended object in two states: one is as follows Figure 5 In one embodiment, both the first adapter 55 and the second adapter 56 are deflected to the inside. In another embodiment, both the first adapter 55 and the second adapter 56 are each rotated outward by 90° with the hinge axis 59 as the center.

[0043] Operation method:

[0044] Before the hoisting operation, the object to be hoisted, i.e. the rocket compartment, is in a vertical position. The hoisting equipment is used to move and lower the hoisting device, so that the load-bearing frame device 5 is moved to the upper part of the rocket compartment. The hoisting device is then lowered so that the load-bearing frame device 5 is perpendicularly connected to the object to be hoisted, and the upper part of the object to be hoisted is fixedly connected to the first adapter 55 and the second adapter 56.

[0045] According to the calculation of the center of gravity of the hoisted object, the mounting positions of the two lifting lugs 6 on the two lifting arms are adjusted to minimize the distance between the connecting line between the lifting points on the first lifting arm 52 and the second lifting arm 53 and the center of gravity of the hoisted object, so as to reduce the overturning moment and make the lifting and overturning operation easier to perform;

[0046] After the connection of the hoisted object is completed, the crane equipment starts to lift, lifts the present lifting tool and the rocket cabin section to a certain height, and then overturns the load-bearing frame device 5 under the action of manual assistance, so that the state of the present lifting tool changes from the vertical state shown in Figure 1 to the horizontal state shown in Figure 6 In this process, the rocket cabin section changes from a vertical posture to a horizontal posture, and then assembly is performed; after the assembly is completed, the connection between the end of the rocket cabin section and the first adapter seat 55 and the second adapter seat 56 is released, the present lifting tool is lifted and transferred by the crane equipment to be separated from the rocket cabin section.
