Description

Special lifting appliance for hanging waste steel bucket of metallurgical casting crane

Technical Field

The utility model relates to a special lifting device for hanging a scrap steel bucket of a metallurgical casting crane.

Background

Because the crane has different functions in the production process, the special lifting appliance adopted by the crane type selection design has different structural forms, for example, a metallurgical foundry crane for lifting a hot metal ladle adopts a fixed gantry hook to lift the hot metal ladle by using a main lifting, adopts a single-hook form by using an auxiliary lifting, and completes the tipping operation of the hot metal ladle by matching with the main lifting, thereby realizing the charging of molten iron into a furnace; the metallurgical bridge crane for hoisting the waste steel bucket uses a gantry hook with four hoisting points (or three hoisting points) to hoist the waste steel bucket and add waste steel into the furnace. The crane has different use functions, the lifting appliance has different structural forms, the structural form of the lifting appliance limits the full use of the functions of the crane, and in order to fully consider the special conditions of positioning, maintenance and fault of the lifting equipment and meet the simultaneous continuous production of the multi-base converter, the special lifting appliance for hanging the scrap steel bucket by the casting crane needs to be designed to meet the production requirement. There are major problems as follows: the casting crane used for steel plants is used for hoisting heavy ladle molten iron, molten steel or liquid slag, and the casting crane with a fixed gantry hook is used, namely, the main hoisting adopts a special hoisting tool for the fixed gantry hook, has single function and can only hoist the molten iron ladle; the steel scrap bucket lifting crane in the same span area can only lift steel scrap through the steel scrap bucket gantry hook lifting appliance. If one metallurgical casting crane in the same bay area breaks down or is in scheduled maintenance shutdown (positioned at a maintenance position), the lifting channel of the scrap steel bucket is blocked, so that the continuous and uninterrupted production of steelmaking smelting operation can be realized by the aid of the main lifting mechanism and the auxiliary lifting mechanism matched with the lifting of the scrap steel bucket by the casting crane, and therefore, a special lifting appliance for the waste steel bucket to be hung by the casting crane needs to be designed, and the using function of the crane is fully exerted to meet production requirements.

Disclosure of Invention

An object of the utility model is to provide a metallurgical casting crane hangs special lifting device of steel scrap fill, do not need artifical auxiliary operation, improve essence safety, under the special circumstances of hoisting equipment location maintenance and trouble, make one of them metallurgical casting crane can change the single hot metal ladle function of hanging, can realize hanging the steel scrap fill after hanging special lifting device, satisfy the continuous production in the time of many furnace bases converter, solve under hoisting equipment maintenance or the fault state, block the influence factor to the converter production that steel scrap handling passageway caused.

The technical scheme that the utility model used is, a special lifting device of metallurgical foundry crane hanging scrap steel fill, two hanging beams around this hoist has, adopt rectangular frame to articulate with it in the middle of two hanging beams to be connected, preceding hanging beam both ends are coaxial respectively setting up and are hanging the trunnion, it is 4400mm to hang the interval between the trunnion, set up two main lifting hooks respectively under the preceding hanging beam bottom surface, a connecting rod is being articulated at back hanging beam top surface middle part, the connecting rod top is setting up rings, set up an auxiliary lifting hook under the back hanging beam bottom surface, three lifting hook is counted altogether around, centre-to-centre spacing between main lifting hook and the auxiliary lifting hook is 3000mm, interval between two main lifting hooks is 2240mm.

Because the rear hook of the casting crane is generally designed into a single-hook form, the rear hook and the crane hanger adopt a 3-hanging-point form, and in order to meet the hinge point angle change caused by the relative height change of a main hook hanger and an auxiliary hook hanger, the hanging point of the auxiliary hook is designed into a hinge connection form capable of rotating 180 degrees along the axis. In order to meet the requirement of main hoisting gantry hook hanging, the front hanging beam is designed to be extended, the center distance of hanging trunnions is designed to be consistent with the center distance of plate hooks of a gantry hook hanger (4400 mm), and 2-point hanging of front hanging points is met. Through the design that metallurgical foundry crane steel scrap fill hung special lifting device, solved because the drawback that former use shoulder pole crossbeam chain hoist mode of hanging exists, through the improved design of mode of hanging, the mode that the cooperation of improved design owner auxiliary hook was hung realizes hanging the function by the automatic of driving worker operation, solves the shortcoming that needs the manual work cooperation operation, hangs, the steel scrap joining mode is safe and reliable more, improves the steel scrap and hangs the operating efficiency, reduces the influence that the speed of driving location was overhauld and is smelted the converter.
