Description

Technical Field

[0001] The utility model relates to a sling, in particular to a sling used for segmenting a conical projectile, and belongs to the technical field of slings. Background Art

[0002] Missiles are typically composed of different segments. During the missile assembly process, specialized hoists are required to transport the missile segments. Improper hoist design can result in uneven force on the missile during lifting, leading to structural damage. Furthermore, for conical missile segments, due to docking requirements, the connection hole at one end is typically not perpendicular to the end face, but rather at a specific angle (i.e., there is a certain angle between the axis of the connection hole at one end and the axis of the conical missile). Therefore, a specialized hoist is required to ensure safety during the lifting of conical missile segments. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] This embodiment provides a lifting device for conical projectile segments, which can ensure the stability and balance of the lifting of the conical projectile segments with high safety.

[0028] like Figure 1 As shown, the lifting device includes: a lifting beam 1, a slider 2, an end flange I3, an end flange II5 and a plurality of wedge-shaped gaskets 4; the lifting device is used for lifting the conical elastic body segment 10.

[0029] The hanging beam 1 is parallel to the axis of the conical body segment 10; two hanging blocks are symmetrically installed on the hanging beam 1 as lifting points (i.e. hanging points) for double-hanging-point lifting.

[0030] As an example, the hanging block adopts a slider 2 that slides with the hanging beam 1. The structure of the slider 2 is as follows: Figure 3 As shown, the middle opening serves as a slide groove and slides with the lifting beam 1 (that is, the lifting beam 1 passes through the slide groove and slides with it); the upper and lower ends of the slider 2 are provided with lifting ears, and the lifting ears are installed with U-shaped shackles 8; the upper U-shaped shackle 8 is used as a hanging point for connecting to the lifting equipment, and double-hanging point lifting is achieved through two sliders 2; the lower U-shaped shackle 8 is connected to the upper end of the sling 7.

[0031] The slider 2 can move on the hanging beam 1 to adjust its position, thereby adjusting the distance between the two hanging points to accommodate the projectile segments of different lengths.

[0032] A row of several positioning holes 9 are provided on the hanging beam 1 along its length direction, and a fixing hole is provided in the middle of the slider 2. When the slider 2 slides on the hanging beam 1 until its fixing hole corresponds to the position of one of the positioning holes 9, the pin 6 is installed in the positioning hole 9 and the fixing hole (that is, the pin 6 is passed through the slider 2 and the hanging beam 1) to fix the slider 2 on the hanging beam 1.

[0033] End face flanges are respectively provided at both axial ends of the conical body segment 10, with the end face flange at the large end being end face flange I3 and the end face flange at the small end being end face flange II5; holes are opened at the upper ends of the end face flange I3 and the end face flange II5 for installing U-shaped shackles; the lower end of the sling 7 is connected to the U-shaped shackle on the end face flange at the corresponding end, thereby realizing the lifting of the conical body segment 10.

[0034] The upper end of the end face flange II5 has an upward extension portion, so that the height position of the U-shaped shackle on its upper end is the same as the height position of the U-shaped shackle on the end face flange I3.

[0035] As an example, the end face flange adopts a cross structure (ie, includes a circular frame and a cross frame arranged in the circular frame), which can reduce the lifting weight.

[0036] In this example, if Figure 2 As shown, there is a certain angle between the axis of the connecting hole at the large end of the conical body segment 10 and the axis of the conical body segment 10, which is an inclined hole; when the connecting hole is directly used to connect the end face flange I3, in order to achieve a stable connection of the end face flange I3, a wedge-shaped gasket 4 is provided at each connecting hole; the end face flange I3 is provided with flange holes corresponding to the connecting holes at the large end of the conical body segment 10, and the flange holes are coaxial with the connecting holes at the corresponding positions at the large end of the conical body segment 10; a wedge-shaped gasket 4 is provided corresponding to each flange hole, and the inclined surface of the wedge-shaped gasket 4 is perpendicular to the axis of the flange hole, that is, the axis of the flange hole is along the normal direction of the inclined surface of the wedge-shaped gasket 4. A fastening hole coaxial with the flange hole is opened on the inclined surface of the wedge-shaped gasket 4, and then the bolt is passed through the fastening hole on the wedge-shaped gasket 4, the flange hole on the end face flange I3 and the connecting hole on the conical elastic body segment 10, and fastened to the inclined surface of the wedge-shaped gasket 4 with a nut, so that the end face flange I3 and the conical elastic body segment 10 can be fixed.
