UTILITARIAN CONTENT

[0004] Therefore, the utility model provides a kind of boiler large-caliber pipeline hoisting and the connecting structure of steel wire rope to solve the technical problem that traditional rope and hoisting ear winding cooperation is prone to rope slipping for large-caliber pipeline.

[0007] Further, the hanging ring is hung with external lifting device, for providing the force point position of external hoisting device to first rope and second rope.

[0008] By adopting the technical scheme, the hanging ring can be firmly hung on the lifting hook or other connecting components of the external lifting device in the lifting process, ensuring that the lifting force can be smoothly transmitted to the ropes, and then the pipeline is stably lifted.

[0009] Further, the other end of the first rope and the second rope is hung on itself through a gourd-shaped padlock.

[0010] By adopting the technical scheme, the stability and safety of the ropes in the lifting process are ensured, and the structure of the gourd-shaped padlock enables the ropes to be firmly connected together and not easily separated due to external force, thereby ensuring the smooth progress of the lifting operation.

[0011] Further, the four mounting ears are arranged in an equidistant ring along the central axis of the pipeline, and the first rope and the second rope pass through each mounting ear.

[0012] By adopting the technical scheme, the balance and stability of the pipeline in the lifting process are ensured, and since the mounting ears are uniformly distributed, they can provide stable support points for the first rope and the second rope, so that the ropes can be uniformly stressed in the lifting process, avoiding pipeline shaking or tilting due to uneven stress.

[0030] The embodiments will be described below according to the overall structure of the utility model. Embodiment one:

[0031] A kind of boiler large-diameter pipeline hoisting and the connecting structure of steel wire rope, such as Figures 1-4As shown, including pipeline 1, the two sides of pipeline 1 are respectively provided with first rope 201, second rope 202, the outer side of pipeline 1 is provided with four mounting ears 5, first rope 201, second rope 202 are in "cross" interlaced structure, support at the bottom of pipeline 1, one end of first rope 201, second rope 202 is provided with hanging ring 4, the staggered arrangement of first rope 201 and second rope 202 forms a stable "cross" support structure at the bottom of pipeline 1, which directly acts on the bottom of pipeline 1 and provides reliable support for it, effectively sharing the weight and pressure in the hoisting process. Compared with the traditional hoisting method, this support structure avoids the direct winding of the rope and the hoisting ear outside the pipeline 1, thereby significantly reducing the risk of rope slipping, and the "cross" support structure also significantly improves the stability and safety of the pipeline 1 during hoisting. Since the rope forms a stable support point at the bottom of the pipeline 1, the pipeline 1 can remain stable during hoisting, reducing the possibility of shaking and tilting.

[0032] Referring to Figure 1 , Figure 2 , hanging ring 4 is hung with external lifting device, for providing the force point of external hoisting device to first rope 201, second rope 202, in the hoisting process, hanging ring 4 can be firmly hung on the lifting hook or other connecting parts of external lifting device, to ensure that the lifting force can be smoothly transmitted to the rope, and then stably hoist the pipeline 1, at the same time, the existence of hanging ring 4 makes the hoisting operation more convenient and safe, because hanging ring 4 usually has high strength and wear resistance, it can withstand the huge tension and friction force generated in the hoisting process, to ensure the smooth progress of hoisting operation.

[0033] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the other end of first rope 201, second rope 202 is hung with itself through the shape of the rope, to ensure the stability and safety of the rope in the hoisting process, the structure of the shape of the rope makes the rope can be firmly connected together, will not easily come off because of external force, so as to ensure the smooth progress of hoisting operation, at the same time, this kind of hanging way also has certain self locking function, in the hoisting process, if the rope is subjected to tension, the shape of the rope will be automatically locked, to prevent the rope from slipping or loosening, this self locking mechanism not only improves the safety of hoisting operation, but also reduces the operation steps needed by the hoisting personnel, improves the work efficiency.

[0034] Referring to Figure 1 , Figure 2 , Figure 3, four mounting ears 5 are arranged along the central axis of the pipeline 1 in equal distance annularly, and the first rope 201 and the second rope 202 penetrate through each mounting ear 5, which ensures the balance and stability of the pipeline 1 during hoisting. Since the mounting ears 5 are uniformly distributed, they can provide stable support points for the first rope 201 and the second rope 202, so that the ropes can be uniformly stressed during hoisting, avoiding the shaking or tilting of the pipeline 1 caused by uneven stress. Meanwhile, the first rope 201 and the second rope 202 penetrate through each mounting ear 5, further enhancing the stability of the hoisting structure. The close cooperation between the ropes and the mounting ears 5 ensures that the hoisting force can be smoothly transmitted to the pipeline 1, ensuring the smooth progress of the hoisting operation.

[0035] Referring to Figure 1 , Figure 2 , Figure 3 , four clamping grooves 3 are formed in the bottom of the pipeline 1, and the first rope 201 and the second rope 202 are clamped inside the clamping grooves 3, which limits the position of the first rope 201 and the second rope 202, providing fixed clamping positions for the first rope 201 and the second rope 202. By clamping the ropes inside the clamping grooves 3, the movement of the ropes during hoisting can be effectively limited, ensuring that they always remain in the predetermined position, thereby enhancing the stability of the hoisting structure. Meanwhile, the clamping effect of the clamping grooves 3 on the first rope 201 and the second rope 202 also prevents the ropes from slipping. Example two:

[0036] Referring to Figure 3 , Figure 4 , hooks 7 are arranged at the bottom of the first rope 201 and the second rope 202, which are buckled outside the clamping grooves 3. The hooks 7 are in the shape of "L" as a whole. By hooking the hooks 7 with the clamping grooves 3, the hooks 7 can be firmly hooked inside the clamping grooves 3, providing stable support points for the first rope 201 and the second rope 202. The ropes are sequentially penetrated through the mounting ears 5 and hooked by the gourd-shaped padlocks, completing the installation and cooperation of the ropes with the pipeline 1. Meanwhile, the other end of the rope is hooked by the lifting device outside, and then hoisting operation is carried out. In this process, the support and hooking of the hooks 7 at the bottom of the pipeline 1 play a key role, which is conducive to directly applying the external hoisting force to the bottom of the pipeline 1, forming a relatively stable hoisting structure. This structure can effectively disperse the pressure during hoisting, reducing the possibility of pipeline shaking and tilting, thereby improving the safety and stability of the hoisting operation.

[0037] Referring to Figure 1 , Figure 2 , Figure 3, and located below the mounting ear 5, in the hoisting process, if the bottom rope slips, the knot 6 will play a key role, because the knot 6 and the mounting ear 5 exist the clamping limiting relationship, when the rope slips, the knot will be clamped on the mounting ear 5, so as to prevent the pipeline 1 from falling, and meanwhile, the stability of the pipeline 1 in the hoisting process is ensured, even if the rope is loose or slips, the clamping of the knot 6 and the mounting ear 5 can provide additional support force for the pipeline, so as to prevent the pipeline from falling, the double protection mechanism not only improves the safety of the hoisting operation, but also provides more safety protection for the operator.

[0038] The implementation principle of the utility model is: when the pipeline 1 needs to be vertically hoisted, first, the first rope 201 and the second rope 202 are staggered and supported at the bottom of the pipeline 1 in the form of a cross, which is similar to the binding of a cake box, and meanwhile, the clamping groove 3 is used to clamp and limit the first rope 201 and the second rope 202, so as to ensure the structural stability of the cross-shaped support structure, then the end is penetrated through the mounting ear 5, then the gourd-shaped padlock at one end is hung with itself, the cooperation of the rope and the pipeline 1 is completed, then the hoisting device outside is used to hang the ring 4 at the other end of the rope and carry out the subsequent hoisting operation, in this embodiment, the cross-shaped support structure formed by the first rope 201 and the second rope 202 at the bottom of the pipeline 1 is beneficial to supporting the bottom of the pipeline 1 in the hoisting process, reduces the probability of rope slipping in the traditional hoisting process, that is, the rope is wound around the hoisting ear outside the pipeline 1, and improves the stability and safety of the pipeline 1 in the hoisting process;

[0039] The clamping groove 3 is arranged on one side to improve the stability of the rope and the cross-shaped structure, and on the other side, when the pipeline 1 is hoisted, the rope can be separated from the pipeline 1 through the clamping groove 3, so as to improve the convenience of separating the rope, and the clamping groove 3 waits for the pipeline to be connected, and then is repaired through the welding technology, so as to ensure the overall integrity of the pipeline 1;

[0040] The knot 6 is arranged below the mounting ear 5, and when the bottom rope slips, the knot 6 is a safety protection mechanism, and the clamping and limiting of the knot 6 and the mounting ear 5 can ensure that the pipeline 1 will not fall, so as to further improve the safety of the pipeline hoisting.

[0041] To provide the second problem solving means for the present application, and the second embodiment, first through the hook 7 and the card slot 3 is hung, according to the above principle, the first rope 201, the second rope 202 in turn through the mounting ear 5, and through the gourd-shaped padlock is hung, complete the rope and pipeline 1 installation cooperation, then, using the outside hoisting device on the other end of the rope ring 4 is hung and after the hoisting operation, in this embodiment, through the hook 7 on the bottom of the pipeline 1 support hanging, it is advantageous to the hoisting force of the outside directly acting on the bottom of the pipeline 1, form a more stable hoisting structure, also can solve the problem proposed in the present application.
