Description
Technical field
The utility model is related to fire-screen door limiting devices before a kind of converter, and fire-screen door limits before belonging to metallurgy industry converter
Position equipment technical field.
Background technology
Fire-screen door is generally fitted provided with before converter, the switch of fire-screen door is controlled by limit switch, avoids making
At door collision or slide down.
Currently, the limit switch mounting distance fire door of fire-screen door is closer, the failures such as scaling loss are easily caused, and personnel handle event
Closer apart from fire door, fire-screen door when barrier, there are the security risks such as larger burn, mechanical wounding.
Utility model content
The utility model aim is to provide fire-screen door limiting device before a kind of converter, can ensure opening for stokehold fire-screen door
It closes, securely and reliably, solves the problems, such as background technology.
The technical solution of the utility model is：
Fire-screen door limiting device before a kind of converter, including column, fixed pulley, steel wire rope, counterweight, fixing bracket one, opening
Limit switch, fixing bracket one and fixing bracket two are separately fixed at column in place for limit switch, fixing bracket two and pass in place
On, fixing bracket one and about two fixing brackets are arranged, reaching a limit switch and pass, limit switch is separately fixed at admittedly in place
On fixed rack one and fixing bracket two, fixed pulley is fixed on the upper end of column, and fixed pulley is equipped with steel wire rope, and steel wire rope is equipped with
Counterweight.
Fire-screen door limiting device before above-mentioned converter, also includes stokehold fire-screen door and hanging ring in composition, and hanging ring is fixed on stove
In preceding fire-screen door, steel wire rope is hung on hanging ring.
It is described reach a limit switch and close the distance between limit switch and the stroke of stokehold fire-screen door match in place.
The column makes for square steel.
The utility model is used, in use, column to be fixed on to the both sides of stokehold fire resistant doorsets, after steel wire rope is by fixed pulley
Being fixed on makes the moving direction of counterweight parallel with the direction of motion of stokehold fire-screen door on the hanging ring in the fire-screen door of stokehold.Work as stokehold
When fire-screen door is opened the door, steel wire rope drives counterweight to move up, and when counterweight, which touches, reaches limit switch, stokehold fire-screen door is stopped
Only move；When stokehold fire-screen door is closed, counterweight moves down, when counterweight, which touches pass, reaches limit switch, stokehold gear
Vent stops movement, avoids the collision of stokehold fire-screen door or slides down.
The utility model has the beneficial effects that：It can ensure the switch of stokehold fire-screen door, securely and reliably, avoid stokehold gear fire
The collision of door or slide down and due to apart from fire door it is relatively close caused by the failures such as scaling loss.
Description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model side view；
Fig. 3 is the utility model fixed pulley scheme of installation；
In figure：Column 1, steel wire rope 3, counterweight 4, fixing bracket 1, reaches a limit switch 6, fixing bracket at fixed pulley 2
27, limit switch 8 in place are closed.
Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1,2,3, fire-screen door limiting device before a kind of converter, including column 1, fixed pulley 2, steel wire rope 3, matching
4, fixing bracket 1 is weighed, a limit switch 6, fixing bracket 27 are reached and closes limit switch 8 in place, fixing bracket 1 and solid
Fixed rack 27 is separately fixed on column 1, and fixing bracket 1 and about 27 fixing bracket are arranged, 6 He of a limit switch is reached
Limit switch 8 in place is closed to be separately fixed on fixing bracket 1 and fixing bracket 27, fixed pulley 2 is fixed on the upper end of column 1,
Fixed pulley 2 is equipped with steel wire rope 3, and steel wire rope 3 is equipped with counterweight 4.
In the present embodiment, column 1 makes for square steel, is uprightly installed on stokehold fire-screen door both sides, fixes on the ground, and
The hanging ring of steel wire rope is welded and fixed in the fire-screen door of stokehold.
In the apical lateral of square steel a fixed pulley 2, the outer of fixed pulley 2 and square steel are welded towards stokehold fire-screen door direction
Outer is concordant.Counterweight 4 is rectangular, and size is less than square steel, and weight and the stokehold fire-screen door of counterweight 4 match.Upper on the outside of square steel,
Lower position difference box cut hole, length about 30CM, width are slightly less than square steel, expose side counterweight.And it is welded on the outside of slot hole solid
Two bottom plates of fixed limit bit switch, the distance between two bottom plates will be matched with the stroke of stokehold fire-screen door, will finally be reached
Limit switch 8 is separately fixed on two bottom plates in place for position limit switch 6 and pass.
When stokehold fire-screen door is opened the door, steel wire rope 3 drive counterweight 4 move up, when counterweight touch reach position limit open
When closing 6, stokehold fire-screen door stops movement；When stokehold fire-screen door is closed, counterweight 4 moves down, and is reached when counterweight 4 touches pass
When the limit switch 8 of position, stokehold fire-screen door stops movement, avoids the collision of stokehold fire-screen door in this way or slides down.
