Description

Technical Field

[0001] The utility model relates to the technical field of rigging, in particular to a round-ring chain mooring rigging. Background Art

[0002] During sea and air transport, large equipment such as vehicles, aircraft and other materials need to be bundled and reinforced. Existing bundling and reinforcement methods include steel wire ropes, polyester belts and chain rings. During reinforcement, the two ends of the bundling reinforcement are respectively fixed on the transportation vehicle and the transported equipment, and then the mooring slings are used to apply pre-tightening force, so the mooring slings are the most important components of the bundling reinforcement. Mooring slings are used to fix equipment that is not in use temporarily to prevent the equipment from moving under the action of external forces, thereby avoiding equipment damage and personal injury. Existing mooring slings are mostly used in conjunction with ropes and chains, and are rarely suitable for tightening and reinforcing round ring chains. At the same time, mooring slings also need to be able to achieve rapid coarse and fine adjustments of the chain, and in special circumstances, be able to quickly release the relevant equipment from the mooring slings. These application scenarios place higher requirements on the properties of mooring slings. Utility Model Content

However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0047] like Figure 1 As shown, it is a schematic diagram of the overall structure of the circular chain mooring rigging of the utility model, including a pair of support guard plates 1, the pair of support guard plates 1 are symmetrically arranged, and the left and right ends are spaced by the first limit column 2 and the second limit column 3 respectively. The left end of the pair of support guard plates 1 is connected with a hook assembly 4 and an adjustment hand wheel 5, one end of the hook assembly 4 is clamped between the pair of support guard plates 1, and is sleeved on the first limit column 2, and the adjustment hand wheel 5 is sleeved on the outer side of the left end of the pair of support guard plates 1. By rotating the adjustment hand wheel 5, the hook assembly 4 can be driven to move left and right inside the pair of support guard plates 1. A self-locking assembly 6 is installed at the bottom of one end of the pair of support guard plates 1 close to the adjustment hand wheel 5, and the self-locking assembly 6 is used to lock the adjustment hand wheel 5 to limit its rotation.

A limit assembly 8 is set on the side of the right end of a pair of support guard plates 1 close to the chain seat 7. The limit assembly 8 is rotatably set on the upper side of the right end between the pair of support guard plates 1, and is used to squeeze the chain seat 7 when the chain seat 7 rotates counterclockwise to the lowest position to limit its clockwise rotation toward the outside of the pair of support guard plates 1.

[0048] The circular link chain mooring sling designed in the utility model can directly hook the transport equipment, meet the requirements of different application scenarios, and improve the safety and reliability of the mooring sling. The mooring sling integrates the hook, fine adjustment, and coarse adjustment into one mechanism, which simplifies the composition structure of the mooring sling. When in use, one end directly hooks the transport equipment through the hook assembly, and the other end is snapped into the circular link chain by the chain body and then flipped to make a coarse adjustment of the length. In the middle, the pre-tightening force of the mooring sling and the length fine adjustment are achieved by rotating the adjustment hand wheel, making the fastening of the mooring sling simpler and more convenient to operate. At the same time, the circular link chain can be quickly tightened and unlocked by rotating the limit assembly, which is simple and convenient to operate and facilitates the rapid disassembly of the mooring sling.

[0049] like Figure 2-3 As shown, in this embodiment, a pair of support guard plates 1 includes a rotating base 11 at the left end and a clamping arm group 12 at the right end, and a groove for clamping the adjustment hand wheel is provided in the middle of the rotating base 11.

When the position of the adjusting hand wheel 5 is determined, the elastic sheet 64 is pressed so that the contact 65 at its front end is snapped into the stop groove 51 on the side of the adjusting hand wheel, so as to achieve the function of anti-loosening self-locking. When the adjusting hand wheel 5 is rotated out, the elastic sheet 64 is pressed to make the contact 65 disengage from the stop groove 51 to release the locked state.

[0052] like Figure 5-6 As shown, in this embodiment, the chain holder 7 is used to buckle the round link chain. The chain holder 7 includes a pair of special-shaped plates 71, a pair of rotating shafts 72 are symmetrically arranged on the outer side of the pair of special-shaped plates 71 and are rotatably arranged on the inner side of the pair of supporting guard plates 1, and a second clamping groove 73 for buckling the round link chain is arranged on the inner side of the top of the pair of special-shaped plates 71. When in use, the round link chain is tightened and buckled into the groove in parallel. A trapezoidal stop plate 74 is arranged at one end of the pair of special-shaped plates 71 facing between the pair of supporting guard plates 1, and the bottom surface of the trapezoidal stop plate 74 is used to abut against the second limiting column 3. The top surface of the trapezoidal stop plate 74 is used to abut against the limiting assembly 8.

[0053] like Figure 7-9As shown, in this embodiment, the limit assembly 8 is a component used to limit the rotation of the round link chain and unlock the round link chain. The limit assembly 8 includes a fixed limit plate 82 and a pair of V-shaped stoppers 83 which are sequentially installed between a pair of support guard plates 1 through a second positioning bolt 81. When the chain holder 7 rotates counterclockwise to the lowest position, the fixed limit plate 82 can drive the pair of V-shaped stoppers 83 to rotate around the second positioning bolt 81 under the drive of an external force. The bottom ends of the pair of V-shaped stoppers 83 are used to abut against the top surface of the trapezoidal stopper plate 74, and the fixed limit plate 82 is clamped into the first clamping groove 13.

[0054] In specific implementation, a fixed horizontal plate 821 is provided at one end of the fixed limiting plate 82 close to the first clamping groove 13, and a pair of connecting plates 822 are provided at the other end of the fixed horizontal plate 821, and the pair of connecting plates 822 are clamped between a pair of V-shaped stoppers 83. A second slide groove 823 sleeved on the second positioning bolt 81 is provided at the front end of the pair of connecting plates 822, and a certain sliding space exists in the second slide groove 823. One end of the fixed horizontal plate 821 close to the V-shaped stopper 83 is clamped in the open groove 831 at the top of the pair of V-shaped stoppers 83, and a limiting spring 832 is respectively installed between the pair of V-shaped stoppers 83 and the pair of connecting plates 822 on both sides. When a pair of connecting plates 822 are pushed to slide along the second slide groove 823 toward one side of the chain seat 7, the end of the fixed cross plate 821 away from the V-shaped stop plate 83 can be rotated counterclockwise into the first groove 13 under the action of external force. At the same time, the limit spring 832 applies elastic force to the fixed cross plate 821 and the V-shaped stop plate 83 respectively, thereby supporting the pair of V-shaped stop plates 83 and squeezing them against the top surface of the trapezoidal stop plate 74 to prevent the chain seat 7 from rotating clockwise.

[0055] In addition, in this embodiment, the limiting assembly 8 also includes a triangular stopper 84 arranged on the second positioning bolt 81, and the triangular stopper 84 is clamped between a pair of connecting plates 822. The triangular stopper 84 can rotate around the second positioning bolt 81 along with the fixed limiting plate 82, and is used to resist the circular link chain in the second slot 73 to limit its sliding out.

[0056] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention.
