Description

Technical Field

[0001] The invention belongs to the technical field of slings, and in particular relates to a special-shaped whole-bullet sling and a lifting method. Background Art

[0002] In order to meet special requirements such as air inlets or aerodynamic layout, the cross-section of some missile bodies (or partial compartments of missile bodies) is not circular, but has a partially protruding special-shaped structure on the basis of a full circle, so that the missile body formed is a special-shaped whole missile; these locally protruding special-shaped structures are mostly below the special-shaped whole missile. When lifting the special-shaped whole missile, the protruding special-shaped structure interferes with the lifting equipment. In order to avoid damage or destruction caused by the protruding special-shaped structure during the lifting or hoisting process, a common method is to rotate the special-shaped whole missile in one direction along the circumference until the protruding special-shaped structure rotates to the top of the special-shaped whole missile, and then lift the special-shaped whole missile. After the special-shaped whole missile is lifted and placed on other tooling or brackets, the special-shaped whole missile is rotated in the opposite direction along the circumference to the initial state.

[0003] The above method requires the special-shaped whole bomb to be rotated at a large angle along the circumferential direction, and requires the tooling or bracket to have a large-angle circumferential rotation mechanism, which increases the complexity of the tooling or bracket and increases the size, weight and cost; at the same time, the special-shaped whole bomb needs to be rotated at a large angle along the circumferential direction before and after lifting, and multiple operators need to cooperate and operate the rotating handwheel synchronously. The operation process is cumbersome and takes a lot of time, which increases the workload and operation difficulty. In addition, the special-shaped whole bomb cannot be directly and quickly lifted onto the bracket, and the lifting efficiency is low, which affects the equipment support efficiency.

[0035] Beneficial effects:

[0036] (1) The present invention adopts a sling and an adapter block to cooperate with each other. The sling ensures that the sling and the contact surface area of ​​the special-shaped whole bullet are in full contact, thereby reducing the pressure and force of the special-shaped whole bullet in the contact surface area;

[0037] At the same time, the sling can be adapted to the lifting of special-shaped whole bombs with different diameters, and has strong versatility. As long as it is within the carrying range of the sling, the special-shaped whole bomb can be lifted, and there is no need to develop multiple types of slings to adapt to the lifting of special-shaped whole bombs with different cross-sectional diameters;

[0038] Installing an adapter block between the sling and the special-shaped whole bomb can meet the needs of locally protruding special-shaped structures arranged at various angles along the circumference of the special-shaped whole bomb, greatly increasing the versatility of the special-shaped whole bomb lifting device and lifting method.

[0039] (2) In the present invention, by adjusting the circumferential positions of the plurality of adapter blocks between the sling and the special-shaped whole bomb, the plurality of adapter blocks are arranged on both sides of the plumb line of the center of mass of the special-shaped whole bomb, so that the plurality of adapter blocks separated on both sides of the plumb line of the center of mass of the special-shaped whole bomb are symmetrical about the plumb line, thereby ensuring that the resultant force applied to the special-shaped whole bomb by the plurality of adapter blocks during the lifting process of the special-shaped whole bomb falls on the plumb line of the special-shaped whole bomb, thereby ensuring that the special-shaped whole bomb will not rotate in the circumferential direction during the lifting process, and there is no need to rotate the whole bomb in the circumferential direction after the special-shaped whole bomb is lifted.

[0040] (3) In the present invention, the special-shaped whole bomb does not need to be rotated at a large circumferential angle before and after the hoisting of the special-shaped whole bomb, and thus the tooling or bracket does not need to have a large circumferential angle rotation mechanism, which reduces the workload and operating difficulty, realizes direct and rapid hoisting of the special-shaped whole bomb, and improves the hoisting efficiency.

[0041] (4) The present invention is applicable to single-lifting point lifting, and only one lifting hook is needed for the lifting equipment to complete the lifting of the entire irregular bomb, thereby reducing the difficulty of lifting operation and improving the lifting security.

[0042] (5) The present invention can also be applied to double-lifting point lifting, that is, lifting of special-shaped whole-body items is performed by two hooks of a lifting device or two hooks provided by more than two lifting devices. The lifting load of a single hook during double-lifting point lifting is half of the lifting load of a single hook during single-lifting point lifting, thereby reducing the load-bearing requirements for a single hook of the lifting device, reducing the difficulty of lifting operation, and improving the lifting security.

DETAILED DESCRIPTION

[0047] In order to better understand the present invention, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] Embodiment 1:

[0049] This embodiment provides a special-shaped whole bomb lifting device, which is used for lifting a special-shaped whole bomb having protruding structures on both sides of the outer surface.

[0050] like Figure 1 As shown, the special-shaped whole-bomb lifting device comprises: one or more lifting units; the lifting unit comprises: a sling 1 and a plurality of adapter blocks, wherein the sling 1 is a flexible sling, which is passed around the special-shaped whole bomb; openings are provided at both ends of the sling 1 for cooperating with the hook of the lifting equipment; a plurality of adapter blocks are provided in the area where the special-shaped whole bomb 6 contacts the sling 1; two adapter blocks are correspondingly provided for each protruding structure, and the two adapter blocks are respectively located on both sides of the protruding structure along the circumference of the special-shaped whole bomb.

[0051] In this example, there is a protruding structure on each side of the outer surface of the special-shaped bomb, namely protruding structure one 7 and protruding structure two 8; based on this, each lifting unit is provided with four adapter blocks, namely adapter block one 2, adapter block two 3, adapter block three 4, and adapter block four 5.

[0052] The sling 1 is a flat belt-shaped structure with an opening at each end for cooperating with the hook; to facilitate the lifting of the hook, the size of the opening is larger than the hook size of the lifting equipment; the length of the sling 1 is larger than the circumference of the special-shaped whole bomb 6; the sling 1 is made of a flexible material, and when it contacts the special-shaped whole bomb 6 and each adapter block (i.e., adapter block one 2, adapter block two 3, adapter block three 4, adapter block four 5) under the action of external force, the contact surface is completely fitted, so that the external force can be evenly applied to the contact area.

[0053] Each adapter block has the same structural dimensions and mass; the adapter block is an arc-shaped block with concentric inner and outer arc surfaces. The radius of the inner arc surface of the adapter block is the same as the radius of the special-shaped whole bomb 6, so that the inner arc surface of the adapter block can fit the outer surface of the special-shaped whole bomb 6; the radius of the outer arc surface of the adapter block is larger than the maximum radial dimension of the protruding structure 1 7 and the protruding structure 2 8 (that is, the adapter block protrudes from the protruding structure 1 7 and the protruding structure 2 8 in the radial direction), thereby preventing the protruding structure 1 7 and the protruding structure 2 8 from contacting the sling 1.

[0054] The two end faces of the adapter block along the axial direction of the special-shaped whole bullet 6 are the front end face and the rear end face. The front end face of the adapter block is parallel to the rear end face. The distance between the front and rear end faces of the adapter block is the width (such as Figure 2 and Figure 3 L2 in the figure is greater than the width of the sling 1 (as Figure 2 and Figure 3 L1); the adapter block is made of a flexible material. When it contacts the special-shaped whole bomb 6 and the sling 1 under the action of external force, the contact surface is completely fitted, and the external force can be evenly applied to the contact area.

[0055] The adapting block is located at the intersection of the two circumferential side surfaces of the special-shaped whole bullet 6 with the inner arc surface and the outer arc surface, and has rounded corners.

[0056] Several adapter blocks are installed between the sling 1 and the special-shaped whole bomb 6, and one adapter block is arranged on both sides of each protruding structure. The adapter block is adjustable along the circumference of the special-shaped whole bomb 6 between the sling 1 and the special-shaped whole bomb 6 (before lifting, the position of each adapter block is manually adjusted).

[0057] When the special-shaped whole bomb lifting device includes an odd number of lifting units, one of the lifting units is arranged at the position of the center of mass plumb line 10 of the special-shaped whole bomb 6 (let it be the central lifting unit), the symmetry line of the sling 1 of the central lifting unit coincides with the center of mass plumb line 10 of the special-shaped whole bomb, and the remaining lifting units are symmetrically arranged on both sides of the center of mass plumb line 10 of the special-shaped whole bomb 6 along the axial direction of the special-shaped whole bomb.

[0058] When the special-shaped whole bomb lifting device comprises an even number of lifting units, the even number of lifting units are symmetrically arranged on both sides of the plumb line 10 of the center of mass of the special-shaped whole bomb along the axial direction.

[0059] As an example, the special-shaped whole-bomb sling is a single-point sling, such as Figure 2 As shown, the special-shaped whole-bullet sling includes a lifting unit, which is arranged at the position of the center-of-mass plumb line 10 of the special-shaped whole-bullet 6, and the center-of-mass plumb line 10 of the special-shaped whole-bullet is in the central symmetry plane of the sling 1; the adapter block 1 2 and the adapter block 3 4 are symmetrical along the center-of-mass plumb line 10 of the special-shaped whole-bullet 6 (i.e., the plumb line passing through the center-of-mass 9 of the special-shaped whole-bullet), and the adapter block 2 3 and the adapter block 4 5 are symmetrical along the center-of-mass plumb line 10 of the special-shaped whole-bullet 6. For a single-hanging-point sling, the rated load of the sling 1 is greater than twice the gravity of the special-shaped whole-bullet 6.

[0060] As an example, the special-shaped whole-bomb sling is a double-hanging-point sling, such as Figure 3 As shown, the special-shaped whole-bullet sling includes two lifting units, which are symmetrically arranged along the axis of the special-shaped whole bullet on both sides of the plumb line 10 of the center of mass of the special-shaped whole bullet 6; in the lifting units on each side, the adapter block 1 2 and the adapter block 3 4 are symmetrical along the symmetry line of the sling 1, and the adapter block 2 3 and the adapter block 4 5 are symmetrical along the symmetry line of the sling 1. For the double-hanging-point sling, the rated load of the sling 1 is greater than one times the gravity of the special-shaped whole bullet 6.
