Description

Technical Field

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

[0002] Structurally, the whole bomb is generally assembled from multiple compartments. The cables of the whole bomb generally have to pass through all the compartments from front to back. For aerodynamic considerations, the cables are generally installed inside the compartments. However, some compartments cannot have cables installed inside due to special requirements such as charging or structure. Generally, the cables are installed on one side outside the compartment, and then a cable cover is installed outside the cable for protection. As a result, the cross-section of the whole bomb (or a partial compartment of the whole bomb) is not left-right symmetrical, and the bomb body formed in this way is an asymmetric structure whole bomb.

[0003] When lifting this type of whole bomb, there is interference between the cable cover and the lifting equipment. In order to avoid damage or destruction of the cable cover due to force during the lifting or hoisting process, the common method is to rotate the whole bomb upward about 90 degrees along the circumferential direction until the cable cover is rotated to the top of the whole bomb, and then lift the whole bomb. After the whole bomb is hoisted on other tooling or brackets, the whole bomb is rotated in the opposite direction along the circumferential direction to the initial state.

[0004] The above method requires the whole bomb to be rotated about 90 degrees in 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 whole bomb needs to be rotated in the circumferential direction at a large angle 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 whole bomb cannot be directly and quickly lifted onto the bracket, and the lifting efficiency is low, which affects the equipment support efficiency. Summary of the invention

[0005] In view of this, the present invention provides an asymmetric whole-shell lifting device, which can realize the lifting of the asymmetric whole-shell, solving the problems that the asymmetric whole-shell needs to be rotated at a large circumferential angle before and after lifting, requires a tooling bracket with a large circumferential angle rotation mechanism, requires multiple people to coordinate and cooperate for synchronous operation, and has low lifting efficiency.

[0006] The asymmetric structure whole bomb lifting device is used for lifting the asymmetric structure whole bomb formed by having a cable cover on one side; the lifting device comprises: a lifting belt and an adapter combination;

[0007] The sling is used to pass around the whole bomb and the adapter and then be connected to the lifting equipment;

[0010] The adapter assembly covers the outside of the cable cover at the position of the sling on the whole bomb through the groove on its inner arc surface. The cable cover is located in the groove on the inner arc surface of the adapter assembly. The cushion block contacts the outer circumferential surface of the whole bomb, and the outer arc surface of the adapter body contacts the sling.

[0011] As a preferred embodiment of the present invention: in the adapter assembly, the inner bottom surface of the groove is an inner arc surface A, and the inner arc surfaces of the two cushion blocks are inner arc surfaces B;

[0016] As a preferred embodiment of the present invention: there is a gap between the inner bottom surface of the groove of the adapter body and the outer wall surface of the cable cover.

[0017] As a preferred embodiment of the present invention, the front end face and the rear end face of the adapter assembly are respectively located at the front and rear sides of the plumb line of the center of mass of the whole projectile, and the distances from the front and rear end faces of the adapter assembly to the plumb line of the center of mass of the whole projectile are equal.

[0018] As a preferred embodiment of the present invention: the adapter body is made of metal material, and the cushion block is made of non-metal material.

[0019] In addition, the present invention provides a method for lifting a whole-projectile with an asymmetric structure, which adopts the above-mentioned whole-projectile lifting device with an asymmetric structure, and comprises the following steps:

[0020] S1: Adjust the whole bomb so that the longitudinal axis of the whole bomb and the symmetry plane of the cable cover are horizontal, start the lifting equipment, adjust the hook of the lifting equipment to just above the center of mass of the whole bomb, move the hook laterally toward the cable cover, and the moving distance is half of the distance between the central axis of the outer arc surface of the adapter assembly and the central axis of the inner arc surface of the adapter assembly, and drop the hook;

[0021] S2: Hang the opening of one end of the sling on the hook of the lifting equipment, and then pass the other end of the sling under the whole bomb and hang the opening of the end on the hook of the lifting equipment. There is a gap between the sling and the cable cover of the whole bomb for placing the adapter assembly;

[0027] Beneficial effects:

[0028] (1) The lifting device of the present invention can realize the lifting of a whole bomb with an asymmetric structure formed by a cable cover on one side through the cooperation of a lifting belt and an adapter combination; and can adapt to the lifting of whole bombs with various cross-sectional circular diameters. As long as it is within the load-bearing range of the lifting belt, whole bombs with various cross-sectional circular diameters can be lifted, and there is no need to develop multiple types of lifting devices to adapt to the lifting of whole bombs with different cross-sectional diameters; the radius of the inner arc surface B in the adapter combination is equal to the radius of the circular surface of the whole bomb, and by adjusting the position of the adapter combination and the hook, it is ensured that the left and right sides of the lifting belt of the whole bomb above the horizontal plane of the longitudinal axis are the same in length and stress state during the lifting process, and the lifting belt will not move circumferentially relative to the whole bomb, thereby ensuring that the whole bomb will not rotate circumferentially during the lifting process, and there is no need to rotate the whole bomb circumferentially after the whole bomb is lifted.

[0029] (2) By adopting the hoist of the present invention, it is not necessary to rotate the whole bomb at a large circumferential angle before and after the whole bomb is hoisted, and thus the tooling or bracket does not need to have a large circumferential angle rotation mechanism, which simplifies the tooling or bracket, reduces the size, weight and cost of the tooling or bracket. At the same time, the operation process of the hoist is simple, which reduces the workload and operation difficulty, and enables the whole bomb to be directly and quickly hoisted onto the bracket, with high hoisting efficiency.

[0030] (3) In the lifting device of the present invention, the circumferential width of the groove on the adapter body is greater than the maximum circumferential width of the cable cover, and the two intersections of the inner arc surface and the outer arc surface of the adapter assembly have rounded corners, which reduces the difficulty of lifting operation and improves the lifting security.

[0031] (4) In the lifting device of the present invention, the adapter body is made of a low-hardness metal material, and the pad is made of a non-metallic material, so that the entire elastic circular surface will not be worn during the lifting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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.

[0038] Embodiment 1:

[0039] This embodiment provides an asymmetric structure whole bomb lifting device, which is used for lifting an asymmetric structure whole bomb formed by having a cable cover 4 on one side of the outer surface.

[0040] like Figure 1 and Figure 2 As shown, the sling comprises: a sling 1 and an adapter assembly 2, wherein the sling 1 is a flat belt structure with two openings at both ends for cooperating with the hook of the lifting equipment, and the size of the openings is larger than the size of the hook of the lifting equipment. The length of the sling 1 is larger than the circumference of the whole bomb 3, and the rated load of the sling 1 is larger than twice the gravity of the whole bomb 3. When hoisting, the plumb line 6 of the center of mass of the whole bomb 3 is located in the central symmetry plane of the sling 1.

[0041] like Figure 3 and Figure 4 As shown, the adapter assembly 2 is covered on the outside of the cable cover 4 where the sling is located on the whole bomb 3 (the adapter assembly 2 only needs to ensure that the sling 1 and the cable cover 4 can be separated), including: an adapter body 201 and two cushion blocks 202, the adapter body 201 is an arc-shaped structure, including an inner arc surface and an outer arc surface; the inner arc surface is provided with a groove axially penetrating the adapter body 201 at the middle position in the circumferential direction, and the groove width (circumferential dimension) is greater than the width of the cable cover 4; the two cushion blocks 202 are symmetrically fixed on the inner arc surfaces on both sides of the groove of the adapter body 201. The overall inner arc surface of the adapter assembly 2 formed in this way is divided into three parts along the circumferential direction, namely the inner bottom surface of the groove (let it be the inner arc surface A) and the inner arc surfaces of the cushion blocks 202 on both sides of the inner arc surface A (let it be the inner arc surface B). In the adapter combination 2, the radius of the inner arc surface B is R1, which is the same as the radius of the whole bomb 3 and can fit on the outer circumferential surface of the whole bomb 3; the radius of the inner arc surface A is R2, which is larger than the maximum radial dimension of the cable cover 4, and the radius of the outer arc surface of the adapter group 2 is R3, which is equal to R1.

[0042] The two inner arc surfaces B of the adapter assembly 2 are coaxial with the inner arc surface A of the adapter assembly 2. The central axis of the outer cylindrical surface of the adapter assembly 2 is in the circumferential symmetry plane of the adapter assembly 2. The central axis of the outer cylindrical surface of the adapter assembly 2 is parallel to the central axes of the two inner arc surfaces B of the adapter assembly 2. The distance between the central axis of the outer arc surface of the adapter assembly 2 and the central axes of the two inner arc surfaces B of the adapter assembly 2 is L1.

[0043] The adapter assembly 2 covers the outside of the cable cover 4 on the whole bomb 3 through the groove on its inner arc surface. The cable cover 4 is located in the groove on its inner arc surface. The pad 202 on the inner arc surface B contacts the outer circumferential surface of the whole bomb 3, and the outer arc surface of the adapter body 201 contacts the sling 1.

[0044] In the adapter assembly 2, the two inner arc surfaces B are respectively located on the two pads 202, and the two inner arc surfaces B are symmetrically distributed about the symmetry plane of the adapter assembly 2. The inner arc surface A is located on the adapter body 201, in the middle of the adapter assembly 2 along the circumferential direction; the symmetry plane of the inner arc surface A is coplanar with the symmetry plane of the adapter assembly 2.

[0045] The two end faces of the adapter assembly 2 along the axial direction are the front face and the rear face, respectively. The front face of the adapter assembly 2 is parallel to the rear face of the adapter block. The distance between the front and rear faces of the adapter assembly 2 (i.e., the width of the adapter assembly 2) is L3. The width of the sling 1 is L4, and L3 is greater than L4. The front face and the rear face of the adapter assembly 2 are respectively on the front and rear sides of the plumb line 6 of the center of mass of the whole projectile, and the distance from the front face of the adapter assembly 2 to the plumb line 6 of the center of mass of the whole projectile is equal to the distance from the rear face of the adapter assembly 2 to the plumb line 6 of the center of mass of the whole projectile.

[0046] As an example, the adapter body 201 is made of metal material, and the two pads 202 are made of non-metal material; the circumferential width of the groove on the adapter body 201 is greater than the maximum circumferential width of the cable cover 4; the two intersections of the inner arc surface B and the outer arc surface on both sides of the adapter body 201 have rounded corners.
