Abstract
The utility model provides a sealed chamber lifting device for a continuous annealing furnace. A fixed pulley is arranged at one side of a rope wheel and consists of a hinge pin and a copper sleeve; the copper sleeve is connected on the hinge pin in a sliding way; the hinge pin is connected on a bracket, a steel rope is wound on the rope wheel and is connected with a sealed roller through the fixed pulley; and the diameter of the rope wheel is equal to or smaller than that of a chain wheel. As the diameter of the rope wheel is shortened to be equal to or smaller than that of the chain wheel, and the fixed pulley is additionally installed, the lifting distance of the sealed roller can be equal to or smaller than the traveling distance of a sealed knife while the spatial position of the sealed roller is ensured, thereby eliminating the interference phenomenon between the sealed roller and the sealed knife, the problem that the sealed knife clasps the sealed roller can be prevented, the bending of an upper roller of the sealed roller and strip steel scratching accidents caused by the same can be avoided, thereby ensuring the product quality and smooth production.
Description
Technical field
The utility model belongs to the mechanical equipment of steel rolling field, particularly a kind of cold rolled silicon steel continuous annealing furnace sealed roller and lifting device that seals cutter of being used for.
Background technology
The lifting device of cold-rolled silicon iron continuous annealing furnace sealing chamber is by domestic supporting making, this lifting device comprises the rope sheave of lift-off seal roller and the sprocket wheel of lift-off seal cutter, on rope sheave and sprocket wheel, be wound with steel cable respectively and for the lifting chain of counterweight, the steel cable the other end is connected on the sealed roller, and lifting chain is connected on the sealing cutter.Rope sheave and sprocket wheel are installed on the same drive shaft, and the rope sheave diameter is ￠ 370mm, and sprocket diameter is ￠ 225mm.Because the rope sheave diameter is greater than sprocket diameter, therefore the stroke that rises in the identical time with the sealed roller of shaft drive is greater than the stroke of sealing cutter, make between sealed roller and the sealing cutter when promoting, to interfere, after the sealing cutter of wedge-shaped cross section rises to certain altitude, the sealed roller top roll can be embraced.Sealed roller top roll both sides temperature difference causes the last bending that does not change, and when crooked sealed roller top roll fell, basic sometimes rotation was not got up, and have to carry out human intervention and handle.Though also can rotate sometimes, height of drop is not enough, cause connecting and move back stove afterbody furnace pressure shakiness, can't satisfy the production needs.If the assurance furnace pressure, the top roll of bending is descended by force, then can cause steel strip surface to scratch, directly influence the up-to-standard rate of finished strip.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, can avoid sealed roller and sealing cutter to interfere mutually, thereby prevent the continuous annealing furnace sealing chamber lifting device that bending does not change on the sealed roller.
For this reason, the solution taked of the utility model is:
A kind of continuous annealing furnace sealing chamber lifting device, comprise rope sheave and sprocket wheel, it is characterized in that, be provided with a fixed pulley in rope sheave one side, fixed pulley is made up of bearing pin and copper sheathing, and copper sheathing is slidingly connected on the bearing pin, bearing pin is connected on rope sheave and the chain wheel drive shaft stool by support, the steel cable that is wrapped on the rope sheave connects sealed roller through fixed pulley, and when guaranteeing the lift-off seal roller, the sealed roller bearing does not bear horizontal pull.
Described rope sheave diameter is equal to or less than sprocket diameter.
Described fixed pulley external diameter is ￠ 45-55mm, and length is 48-58 mm.
Horizontal throw between described fixed pulley axis and rope sheave and the chain wheel drive axis is 150-170 mm.
The beneficial effects of the utility model are:
Since the utility model with the rope sheave reduced to≤sprocket diameter, installed simultaneously fixed pulley again additional, can guarantee the locus of sealed roller, can make the stroke of the stroke≤sealing cutter of sealed roller rising again, thereby the interference when eliminating lifting between sealed roller and the sealing cutter, prevent to seal the problem that cutter is embraced sealed roller, avoid the bending and the consequent band steel scuffing accident of sealed roller top roll, guarantee the direct motion of quality product and production.
Description of drawings
Accompanying drawing is a continuous annealing furnace sealing chamber lifting device structure synoptic diagram.
Among the figure: sealed roller 1, sealing cutter 2, steel cable 3, lifting chain 4, support 5, bearing pin 6, copper sheathing 7, sprocket wheel 8, rope sheave 9, bearing 10.
Embodiment
By accompanying drawing as seen, continuous annealing furnace sealing chamber lifting device comprises sealed roller 1, sealing cutter 2, steel cable 3, lifting chain 4, support 5, sprocket wheel 8, rope sheave 9, bearing 10 and fixed pulley.The utility model to ￠ 215mm, makes it to be slightly less than the diameter of sprocket wheel 8 with the reduced of rope sheave 9.Install a fixed pulley of forming by bearing pin 6 and copper sheathing 7 simultaneously in the left side of rope sheave 9.Copper sheathing 7 external diameters are that ￠ 50mm, length are 50mm; Bearing pin 6 diameters are identical with copper sheathing 7 internal diameters, are ￠ 30mm; Copper sheathing 7 slides and is embedded in outside the bearing pin 6.Bearing pin 6 is connected on the support 5, and 5 on support is welded on the bearing 10 of rope sheave 9 and sprocket wheel 8.Horizontal throw between the drive axis of the axis of fixed pulley bearing pin 6 and rope sheave 9 and sprocket wheel 8 is 160 mm.The steel cable 3 that is wrapped on the rope sheave 9 connects sealed rollers 1 through fixed pulleys (outer rim of copper sheathing 7), and the other end of the lifting chain 4 on the sprocket wheel 8 connects sealing cutter 2.
