AI Technical Summary

Technical Problem

When the flare opening in front of the kocks rolling mill is installed, the use of ordinary linear spreaders can easily lead to crooked pulling and inclined lifting, which may cause impact damage to the limit of the rotation mechanism, and insufficient rigidity during lifting may lead to the risk of fracture.

Method used

Design a spreader for lifting the front flare of Kocks. By selecting three sections of I-shaped steel with different lengths for welding, a "U" type spreader is formed, and hanging ears are set at both ends to avoid the kocks protective cover. The raised portion of the rotating part realizes safe lifting.

Benefits of technology

The spreader can completely avoid the protruding parts of the rotating part, reduce operation risks, improve operation convenience, achieve operation stability and safety, and avoid the risks of crooked pulling and slanting hanging and breaking.

Description

Technical Field

[0001] The invention relates to the field of kocks rolling mills, in particular to a hoisting device for hoisting a front bell mouth of a kocks. Background Art

[0002] A steel guide bell is set in front of the KOCKS mill of the RSB rolling mill in the big rod plant; the bell in front of the KOCKS mill is in an embedded state, and above it is the KOCKS protective cover rotating mechanism. If ordinary linear hoists are used, it will cause crooked pulling and slanting. Improper lifting will cause impact damage to the rotating mechanism limit. The lack of rigidity of ordinary hoists will cause the risk of breakage during the lifting process.

[0003] Therefore, a special lifting device is needed for this type of operation. It can avoid the rotating part of the protective cover while maintaining stable clamping, reduce operational risks and improve operational convenience. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a hoisting device for hoisting the front bell mouth of kocks, which improves the hoisting operation when the front bell mouth of the kocks rolling mill is assembled on the line, reduces the risk of hoisting operation, and achieves stability and safety of operation.

[0005] Technical solution: The invention discloses a lifting device for lifting the front bell mouth of kocks, which is characterized by: three sections of I-beams of different lengths are selected for welding to form a "U"-shaped lifting device, and hanging ears are arranged at both ends. During use, the lifting device can avoid the raised part of the rotating part of the kocks protective cover to achieve safe lifting.

[0006] Wherein, the cross-sectional dimensions of the three sections of I-beams of different lengths are 120 mm×120 mm.

[0007] The lengths of the three sections of I-beams of different lengths are 1200mm, 1200mm and 3500mm respectively.

[0008] The three sections of I-beams of different lengths are connected by welding, that is, two 1200mm short steels are welded to two ends of a 3500mm long steel, forming a "U"-shaped structure as a whole.

[0009] Wherein, two hanging ears are welded in sequence on both sides of the short steel as the connecting parts for connecting the crane hoisting wire rope and the connecting parts for connecting the bell-mouth hoisting hook.

[0010] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention selects three sections of I-beams of different lengths for welding to form a "U-shaped" sling, with hanging ears set at both ends. During use, the sling can completely avoid the raised part of the rotating part of the kocks protective cover to achieve safe lifting. The present invention improves the lifting operation when the front bell mouth of the kocks rolling mill is assembled on the line, reduces the risk of lifting operation, and achieves stability and safety of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION

[0012] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0013] The lifting device for lifting the front bell mouth of the kocks of the present invention selects three sections of I-beams of different lengths for welding to form a "U"-shaped lifting device, and hanging ears are arranged at both ends. During use, the lifting device can avoid the raised part of the rotating part of the kocks protective cover to achieve safe lifting.

[0014] The cross-sectional dimensions of the three sections of I-beams of different lengths of the present invention are 120mm×120mm. The lengths of the three sections of I-beams of different lengths are 1200mm, 1200mm and 3500mm respectively. The three sections of I-beams of different lengths are connected by welding, that is, two 1200mm short steels are welded to the two ends of the 3500mm long steel, and the whole is a "U"-shaped structure. Two hanging ears are welded on both sides of the short steel in sequence as the connection part for connecting the crane hoisting wire rope and the connection part with the bell-mouth hoisting hook.

[0015] The lifting device for lifting the front bell mouth of kocks of the present invention comprises the following steps when used:

[0016] 1) Use the 3-section model 120*120 as the base of this spreader;

[0017] 2) After measuring the size of the rotating mechanism of the kocks protective cover, determine that the lengths of the three sections of H-shaped steel are 2*1200mm and 3500mm respectively;

[0018] 3) Weld three sections of H-shaped steel, that is, weld 2*1200mm short steel to both ends of 3500mm long steel, forming a "U" shape as a whole. When the crane is lifted vertically, the rotating parts can be completely avoided. At the same time, the overall rigidity is high, and it is relatively convenient to place when not in use;

[0019] 4) Two hanging ears are welded on both sides of the short steel in sequence as the connection parts for connecting the crane hoisting wire rope and the connection parts for the bell-mouth hoisting hook;

[0020] 5) During specific use, the workpiece is connected with a steel wire rope. After being lifted by a crane, the lower end is connected to the bell mouth. The rotating part can be completely avoided during lifting, and there will be no crooked or slanted lifting phenomenon, and the bell mouth can be stably placed in the slide groove.

[0021] The present invention selects three sections of I-beams of different lengths for welding to form a "U-shaped" sling, with hanging ears arranged at both ends. During use, the sling can completely avoid the raised part of the rotating part of the kocks protective cover to achieve safe lifting. The present invention improves the lifting operation when the front bell mouth of the kocks rolling mill is assembled on the line, reduces the risk of the lifting operation, and achieves stability and safety of the operation.
