Background technology
Mammoth conveter equipment is heavy, size is big, and the integral hoisting difficulty is big.Site operation adopts furnace crown, shaft, furnace bottom segmentation lifting group separately right.Because furnace bay does not have lifting machine, can't directly lift, conventional way is on the factory building Vierendeel girder lifting point to be set, utilize hanging devices such as tackleblock, jack, windlass to remove and installing converter, yet this method precondition is the supporting capacity of mill construction can satisfy weight of equipment, so need check Vierendeel girder, original mill construction be carried out interim consolidation process, thereby can not guarantee construction safety and construction period requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of sulky derrick that lifts usefulness, being used for converter body removes and installs, solve converter and removed the lifting problem of installing, this sulky derrick not only makes things convenient for installation, adjusts flexibly, and manufacture craft is simple, the dismounting facility that finishes of constructing, and can reuse, for the lifting of converter body provides reliably auxiliary lifting device, guarantee construction quality, shorten the construction period.
The utility model comprises: sulky derrick body, shaft hanger, tackleblock, shackle.The column suspension column of sulky derrick body and the welding of backing ring boundary belt, vertical mutually; The shaft hanger is corresponding to the gusset hanger and the welding of furnace shell inwall of sulky derrick body; Tackleblock connects the sulky derrick gusset by shackle one end, and the other end connects the furnace shell hanger.
The sulky derrick body is made up of column, horizontal support, diagonal ligament, web plate, abacus, post support, gusset (hanger), the sulky derrick body is connected by tackleblock, shackle with the shaft hanger, promotes or the decline furnace shell under the traction of windlass by tackleblock.
Each parts of sulky derrick body are welded to connect, three root posts become equilateral triangle to distribute, flange plate is towards the triangle center direction, three groups of posts support and are welded on the column both sides, weld with column and backing ring respectively at two ends, and three horizontal supports and three diagonal ligaments weld with column respectively, and passing through up and down in the middle of the horizontal support, two circular web plates weld, abacus and column, horizontal support, diagonal ligament welding, gusset (hanger) and column, horizontal support welding; Manual welding is adopted at each position.
Be separated by on backing ring each 120 ° and determine that be the column putting position at 3, actual measurement platform absolute altitude is made sulky derrick according to distance and backing ring size under furnace shell height and the stove.Sulky derrick is installed and is adopted the mobile crane lifting, on backing ring, weld sulky derrick, furnace shell inwall welding shaft hanger, three cover 60t tackleblock and 80t shackles are set, with tackleblock shaft is hung up properly, subtract furnace shell gravity by the pulley component, slowly the decline furnace shell is removed under the traction of windlass, step was identical when shaft was installed, and slowly the rising furnace shell is installed under the traction of windlass.Treat that furnace shell is removed or installation back cutting disassembling sulky derrick.
The beneficial effects of the utility model are, can interim suspension centre be set for the dismounting and the installation of shaft, do not need lifting overhead traveling crane and the load-bearing of factory building Vierendeel girder, guarantee construction quality and safety, and are simple in structure.
