Abstract
The invention relates to a lifting appliance for installing a blast furnace shell. The lifting appliance (1) is in equilateral triangle shape; a three-side support (6) is connected through angle connecting plates (5); simultaneously, the three angle connecting plates (5) are connected with three suspenders (4); each suspender (4) is provided with a batten plate (3) and is connected with the angleconnecting plate (5); a lifting lug (7) is connected with the angle connecting plates (5) by passing through the suspenders (4) and is provided with an upper lifting hole (15) and a lower lifting hole(16); the two lifting holes for hoist are respectively provided with a double-faced reinforcing ring (8); the three-side support (6) is connected with a pull rod (10) through a connecting plate (9);the pull rod (10) and the suspender (4) are connected on a triangular central connecting plate (2); and the lifting appliance (1) is a stable structure on the whole. The invention has the advantages of simple structure, convenient operation and good overall mechanical property, greatly saves working hours, reduces the labor intensity of workers, and ensures the quality of the blast furnace shell.
Description
One, technical field:
The present invention relates to a kind of suspender, particularly relate to a kind of lifting appliance for installing last furnace shell.
Two, background technology:
In recent years, along with the develop rapidly of China's blast furnace ironmaking art, each newly-built furnace volume of big steel mill is increasing, has increased the blast furnace mounting hardness.In blast furnace was installed, the installation of furnace shell was the emphasis of construction, also is difficult point, to operation effectively be connected, the reduction of erection time plays key role.At present, last furnace shell is bigger because of its structure external form, and furnace shell is installed needs to adopt goliath to be divided into how band is installed, at furnace shell many suspension centres are set during installation, connect the furnace shell suspension centre with rope one end, the other end and hoisting crane gib head direct connection lift, and lifting puts the back in place in the high-altitude welding.Shortcoming is that the horizontal component of force that lifts the rope pull generation causes shell deformation easily, and it is right to need correction earlier to organize after the distortion, has increased the aloft work difficulty, both increased labor strength, make the duration extend again, cost strengthens, and the integral body of housing and presentation quality all are difficult to guarantee simultaneously.
Three, summary of the invention:
The present invention is for overcoming above-mentioned the deficiencies in the prior art, propose a kind of simple in structure, easy for operation, synchronism is strong, the good a kind of lifting appliance for installing last furnace shell of whole mechanical property, suspender (1) is the equilateral triangle shape, suspender (1) three limit is supported (6) and is connected by corner connection plate (5), simultaneously be connected with three suspension rods (4) at three corner connection plates (5), suspension rod (4) is provided with batten plate (3), suspension rod (4) is connected with corner connection plate (5), hanger (7) passes suspension rod (4), corner connection plate (5) is connected with it, hole for hoist (15) is set on hanger (7), following hole for hoist (16), two hole for hoist positions are established two-sided reinforcing pad (8) respectively, (6) are supported by connecting panel (9) cylinder lever connecting rod (10) in three limits, pull bar (10) is concentrated with suspension rod (4) and is connected on the triangle center connecting panel (2), and suspender forms a rock-steady structure on the whole.
Advantage of the present invention be simple in structure, easy for operation, synchronism is good, stable height, the whole mechanical property of suspender are good, the horizontal component of force of having avoided lineoutofservice signal pull to produce when the handling furnace shell causes shell deformation, it is right that but special quality is finished blast furnace every band furnace shell installation group, save man-hour greatly and reduce labor strength, also guaranteed the last furnace shell quality simultaneously.

Five, the specific embodiment
Embodiment one: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, suspender (1) is the equilateral triangle shape, suspender (1) three limit is supported (6) and is connected by corner connection plate (5), simultaneously be connected with three suspension rods (4) at three corner connection plates (5), suspension rod (4) is provided with batten plate (3), suspension rod (4) is connected with corner connection plate (5), hanger (7) passes suspension rod (4), corner connection plate (5) is connected with it, hole for hoist (15) is set on hanger (7), following hole for hoist (16), two hole for hoist positions are established two-sided reinforcing pad (8) respectively, (6) are supported by connecting panel (9) cylinder lever connecting rod (10) in three limits, pull bar (10) is concentrated with suspension rod (4) and is connected on the triangle center connecting panel (2), and suspender forms a rock-steady structure on the whole.During installation, last lifting rope (14) connects the last hole for hoist (15) of hoisting crane (17) gib head and suspender (1) hanger (7), following lifting rope (12) connects hanger (7) hole for hoist (16) and last furnace shell (11) down, hoisting crane (17) lifts by crane afterwards, and suspender (1) drives furnace shell (11) and finishes the last furnace shell installation.
