Abstract

The utility model relates to a gantry crane rigging, in particular to a special gantry crane rigging for the slow cooling of a circular steel bar, comprising a carrying pole beam and a hanger arranged above the carrying pole beam, wherein a pair of ramshorn hooks, a pair of chain hooks, a pair of symmetrical hooks and a single hook are arranged below the carrying pole beam. the number of the steels brought to the grass for eight hours is 450 ton, and the lifting safety can be greatly improved. According to the utility model, the gantry crane rigging can perform the operation of collecting, bringing to the pit, bringing to the grass and the like in the circular steel bar slow cooling process, more importantly, can greatly relieve the bending of the high temperature slow cooling steel, the gantry crane rigging has the characteristics of high efficiency and good adaptability and safe characteristic, and can improve the slow cooling efficiency by 30%, thereby improving the yield and the quality.

Description

The special-purpose gauntry crane rigging of round steel bar slow cooling

Technical field

The utility model relates to a kind of gauntry crane rigging, the special-purpose gauntry crane rigging of a kind of specifically round steel bar slow cooling.

Background technology

Special steel manufacturing enterprise is in the complexity of steel slow cooling link owing to operation, operation process relates to packing, the handling of high-temperature steel, the conversion of process handling mode, the handling of going into the hole, going out hole, steel subsequent treatment (aligning, pickling etc.) etc., the middle operation of realization that needs is very many, cause the Current Collector Sleave of simple function to need a variety of, and in operation process, the conversion of these Current Collector Sleaves was both lost time, and had a strong impact on operating efficiency and safety again.

Domestic round steel bar manufacturing enterprise, slow cooling link at steel does not also have unified job specification and slow cooling technological standards, each manufacturing enterprise all is according to enterprise practical conditions, mechanism form according to burial pit, the mechanism form of cold bed, the relative position of burial pit and cold bed, differences such as the steel grade specification length of slow cooling steel and take different slow cooling work patterns, but what be difficult in the slow cooling link avoid is that the high temperature steel are very easy to crooked in annealing process more than 600 ℃, a lot of enterprises are because the control of slow cooling link is bad, the steel bending phenomenon is very serious, cause the unusual difficulty of steel straightening processing after the slow cooling, big curved steel can't efficiently be handled at all.Under the insurmountable situation of this contradiction, a lot of enterprises have dropped to the temperature of slow cooling about 400 ℃, but require from the retarded cooling process of steel, the real purpose of basic out of reach slow cooling.Solve high-temperature steel at slow cooling link buckling problem, mainly to be that high-temperature steel is produced by external force easily crooked by analyzing, in addition in that to go into this link of hole difficult with control.The good handling mode bending generation of link high-temperature steel annealing process to a great extent.

Summary of the invention

Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, the special-purpose gauntry crane rigging of a kind of round steel bar slow cooling is proposed, make in the round steel bar retarded cooling process process hoist tool of collecting, go into to cheat, go out operations such as hole have commonality, can alleviate the crooked situation that high temperature slow cooling steel produce significantly.

The technical scheme that the utility model solves above technical matters is:

The special-purpose gauntry crane rigging of round steel bar slow cooling comprises shoulder pole girder and is located at the hanger of shoulder pole girder top that the shoulder pole girder below is provided with a pair of ramshorn hook, a pair of rope chain hook, a pair of symmetrical hook and a single hook.

Single hook is positioned at the centre of shoulder pole girder, and symmetrical hook is symmetricly set on the both sides of single hook, and the rope chain hook is symmetricly set on the outside of symmetrical hook, and ramshorn hook is symmetricly set on the outside of rope chain hook.

The utility model has the advantages that: the slow cooling operation in slow cooling steel (bar round steel) production process and follow-up all handlings of processing such as aligning can be finished by the special-purpose gauntry crane rigging of round steel bar slow cooling of the present utility model, the Current Collector Sleave conversion has been saved in the centre, wherein the rope chain hook plays very big facilitation to avoiding into the hole steel bending, the handling mode that goes out to cheat the efficiency ratio past of slow cooling steel improves 2 times (per 8 hours of past only can go out to cheat about 150 tons of steel in addition, and went out to cheat about 450 tons of steel in present 8 hours), and go into the hole, the safe lifting that goes out the hole significantly improves.The utility model can well solve in the round steel bar retarded cooling process process and collect, goes into to cheat, go out the commonality of the hoist tool of operations such as hole, the more important thing is that can alleviate high temperature slow cooling steel significantly produces crooked situation, have characteristics such as efficient, safety, comformability are good, can improve slow cooling operating efficiency 30%, thereby promote the raising of output, quality.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Embodiment one

The structure of present embodiment as shown in Figure 1, the special-purpose gauntry crane rigging of round steel bar slow cooling, comprise shoulder pole girder 9 and be located at the hanger 8 of shoulder pole girder 9 tops, below shoulder pole girder 9, be provided with a single hook 4, bilateral symmetry at single hook 4 is provided with a pair of symmetrical hook 3 and 5, be arranged with a pair of

rope chain hook

2 and 6 in the outside of symmetrical hook 3 and 5, be arranged with a pair of ramshorn hook 1 and 7 in the outside of

rope chain hook

2 and 6.

Ramshorn hook 1 and 7 is 10 tons of rockery hooks; Rope

chain hook

2 and 6 is 8 tons of rope chain hooks; Symmetry hook 3 and 5 is 10 tons of symmetrical hooks; Single hook 4 is 10 tons of single hooks; Hanger 8 is 15 tons of hangers; Shoulder pole girder 9 is 15 tons of gantry shoulder pole girders.Wherein rockery hook 1 and 7 pairings are used, and are used for guaranteeing that non-ring type slow cooling special chain packing slow cooling material goes into the hole, goes out to cheat operation;

Rope chain hook

2 and 6 pairings are used, and are used for guaranteeing that the ring type slow cooling specializes in chain packing slow cooling material and go into the hole, go out to cheat operation; Symmetry hook 3 and 5 pairings are used, and are used for guaranteeing to use aligning the handling that the gentle cold material of stand takes off chain on the non-slow cooling material of steel rope handling; Single hook 4 general independent uses are used for guaranteeing the handling of burial pit hole cover plate and middle plate, possess all functions that can realize of general single hook certainly.28 tons of

chain hooks

2 and 6 can solve more than 600 ℃ high temperature slow cooling steel go into to cheat to guarantee on the link steel safe, efficiently be in steadily after going into the hole, neat, unfold state, be unlikely to because each other extruding causes steel serious crooked (because the high temperature steel are very easy to cause bending because of external force), and improve more than 2 times going out to cheat Link Efficiency.

The needed Current Collector Sleave of a plurality of operation process of the utility model is fused on the Current Collector Sleave, in aspect modern designs such as the layout of function allocation, suspension hook (ear), the length of rope chain hook, the dead-weight capacity of hook are provided with, reasonable, has practicality.

The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of the utility model protection.
