Abstract
The utility model belongs to the field of metallurgical continuous-casting equipment and relates to taper-deviation preventing mechanism for crystallizer width-regulating device. The mechanism consists of a hand wheel (1), a locking plate (2), a worm gear pair (3), checknut pairs (4), a pin axle (5), a narrow-edged press plate (6) and a square pin axle (7), wherein a screw pair has a left and a right checknut pairs (4); the width-regulating device has the pin axle (5), the square pin axle (7) and the narrow-edged press plate (6) in fitting connection; the box body of the worm gear pair (3) has the locking plate (2), which connects with the hand wheel (1); the worm gear pair (3) is in driving connection with the screw pair. The taper-deviation preventing mechanism for crystallizer width-regulating device prevents crack or steel leakage accidents caused by taper deviation and creates favorable conditions for high quality, high efficiency and high output.
Description
Technical field: it is the anti-tapering sideslip mechanism of a kind of crystallizer Width adjusting device that the utility model belongs to the metallurgical continuous casting apparatus field.
The anti-tapering sideslip mechanism of the utility model continuous casting installation for casting crystallizer Width adjusting device is that a kind of strand that makes is in casting cycle, it is mainly used in the special entity that the conical degree of crystallizer of limit setting changes in the conticaster production, prevents that the strand that conical degree of crystallizer direction generation deviation causes from cracking and bleed-out.
Background technology: at present, the domestic worm gear pairs that on the crystallizer Width adjusting device, generally adopts, the leading screw single nut is paid, bearing pin and the embedded connected mode of narrow limit pressing plate.The greatest drawback of this structure is: not self-locking of worm gear pairs: the leading screw single nut is paid because mismachining tolerance and long-time the use are worn and torn; Bearing pin is excessive with the embedded opening that is connected of narrow limit pressing plate; Cause the leading screw single nut to pay excesssive gap, mould reverse taper sideslip, thereby the generation that produces strand crackle and bleed-out accident.
Summary of the invention: provide a kind of crystallizer Width adjusting device to prevent tapering sideslip mechanism on the purpose of this utility model,, thereby created advantage for high-quality, efficient, high yield with crackle and the bleed-out accident that prevents that the tapering sideslip from causing.
The purpose of this utility model is to realize like this, design the anti-tapering sideslip mechanism of a kind of crystallizer Width adjusting device, it is characterized in that: it by handwheel, latch, worm gear pairs, stop nut pay, bearing pin, narrow limit pressing plate, square bearing pin form, leading screw has been paid left and right two stop nuts and has been paid, there are bearing pin and square bearing pin to be connected on the worm gear pairs casing at Width adjusting device latch is arranged with narrow limit pressing plate formula, latch is connected with handwheel, after regulating latch conical degree of crystallizer is mixed up by handwheel.
Characteristics of the present utility model are: pay with the leading screw single nut, the embedded connected mode of bearing pin and narrow limit pressing plate relatively, pay by leading screw and to be added with left and right two stop nuts and to pay, there are bearing pin and square bearing pin to be connected at Width adjusting device with narrow limit pressing plate formula, on the worm gear pairs casing latch is arranged, latch is connected with handwheel, after regulating latch conical degree of crystallizer is mixed up by handwheel.Can prevent crackle and bleed-out accident that the tapering sideslip causes, thereby create advantage for high-quality, efficient, high yield.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Description of drawings: Fig. 1 is the example structure schematic diagram.
Among the figure, 1, handwheel; 2, latch; 3, worm gear pairs; 4, stop nut is paid; 5, bearing pin; 6, narrow limit pressing plate; 7, square bearing pin.
The specific embodiment: Fig. 1 be the anti-tapering sideslip mechanism of a kind of crystallizer Width adjusting device it by handwheel 1, latch 2, worm gear pairs 3, stop nut pay 4, bearing pin 5, narrow limit pressing plate 6, square bearing pin 7 form, leading screw has been paid left and right two stop nuts and has been paid 4, has reduced mismachining tolerance and wearing clearance; There are bearing pin 5 and square bearing pin 7 to be connected at Width adjusting device with narrow limit pressing plate 6 formulas, ward off and exempted from excessive defective worm gear pairs 3 casings of embedded connection opening latch 2 is arranged, latch 2 is connected with handwheel 1, after regulating latch 2 conical degree of crystallizer is mixed up by handwheel 1, prevent from watering steel when vibration, worm gear pairs in the crystallizer Width adjusting device (can not self-locking) is paid and is reversed owing to leading screw.
The utility model by two stop nuts about leading screw pay, bearing pin and square bearing pin be connected with the formula of narrow limit pressing plate, the locking of latch is to reduce strand crackle and the bleed-out that the tapering sideslip causes, present this special entity and operation principle still belong to internal blank, after using this mechanism, can realize that many Bao Lian water, and boost productivity.It is easy and simple to handle, should keep in repair.Still belong to blank at present at home, only I do and have adopted in the horse steel 250X1400 slab caster project this device to facts have proved that the anti-tapering sideslip mechanism of this Width adjusting device is effective, simple in structurely am convenient to make, install, adjust, change, maintenance, saves the energy.
