CN201250589Y - Oscillating-type rolling shutter door device with rails - Google Patents

Abstract

The utility model provides an oscillating-type rolling shutter door device with rails, which is used for a seal protector for sealing rolling mills and preventing latex emulsion from splashing around during steel rolling. The oscillating-type rolling shutter door device comprises a rolling shutter door lifting gear, a rolling shutter door, rolling shutter door rails, an upright support, an air cylinder and a four bar linkage mechanism. The upright support is fixed on both sides of the fixed rail of a roll changing carriage; one end of two oscillating connecting rods of the four bar linkage mechanism is articulated with the inner side of the upright support, and the other end is articulated with the rolling shutter door rail; the air cylinder is articulated with the bottom of a rolling mill platform and the rolling shutter door rail respectively; when the roll of the rolling mill is replaced, the rolling shutter door lifting gear rolls up the rolling shutter door; the air cylinder drives the four bar linkage mechanism to oscillate the rolling shutter door rail, thus ensuring the butt-welded side seam of a traveling rail and the fixed rail within 2mm. When the rolling mill rolls steel, the rolling shutter door lifting gear lowers the rolling shutter door. The air cylinder drives the four bar linkage mechanism to oscillate the rolling shutter door rail down, thus sealing the rolling mills and preventing latex emulsion from splashing around. The utility model has the advantages of simple and novel structure, and being maintained conveniently.

Description

Track wobble formula roller door arrangement

Technical field

The utility model relates to a kind of track wobble formula roller door arrangement, is used for steel rolling and produces the sealing protector that the sealing milling train is avoided emulsion splash everywhere.

Background technology

At present, on the production line of steel plate rolling, roller door arrangement is housed, is used for milling train sealing protection; The roll changing carriage trapped orbit generally is positioned at milling train sealing inboard and is covered by rolling door, owing to limited by technology and place, the roll changing carriage moving track only laterally moves during roll change, can not interfere with the roller door arrangement of milling train sealing, and the mobile roll change track of milling train is positioned at the milling train sealing outside; Therefore the rolling door track is welded on two root posts of fore side clad and can not moves, purpose is to prevent emulsion splash in the milling train when working for milling train to the outside, and rolling door is rolled carrying out smoothly in order to roll change work during roll change.Because design reasons, seam is excessive when rolling mill changer moving track and trapped orbit butt joint, is far longer than the designing requirement of 2mm, and rolling mill changer produces when running to moving track and trapped orbit joint and pitches, easily cause roll to come off, damage steel rolling equipment.

Summary of the invention

The designing requirement of seam in 2mm when the utility model purpose is intended to satisfy rolling mill changer moving track and trapped orbit butt joint, overcome the shortcoming and defect that milling train sealing protection roller door arrangement exists in the existing steel rolling production, a kind of track wobble formula roller door arrangement is provided, this device is provided with cylinder and four jointed gear units, when roll changing carriage moving track and trapped orbit butt joint, the rolling door lifting gear is rolled rolling door; Simultaneously cylinder drives four jointed gear units the rolling door track wobble is risen, thus the designing requirement of seam in 2mm when having guaranteed moving track and trapped orbit butt joint.

Technical solution of the present utility model is achieved in that

A kind of track wobble formula roller door arrangement comprises rolling door lifting gear, rolling door, rolling door track and column support, it is characterized in that: also comprise cylinder and quadric chain; The column support is fixed on roll changing carriage trapped orbit both sides, described rolling door lifting gear is fixed on milling train platform top, two swing connecting bar one ends of quadric chain and column support hinged inside, the other end and rolling door track are hinged, cylinder respectively with milling train platform bottom and rolling door track upper articulation.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model is provided with cylinder and quadric chain, and during the rolling mill roll change, the rolling door lifting gear is rolled rolling door; Simultaneously cylinder drives four jointed gear units the rolling door track wobble is risen, and makes roll changing carriage moving track and the mutually noninterfere of milling train closed system, thus the designing requirement of seam in 2mm when having guaranteed that moving track and trapped orbit dock.

2, during rolling mill steel rolling, the rolling door lifting gear is fallen rolling door; The while cylinder drives four jointed gear units the rolling door track wobble is fallen, and the sealing milling train is avoided emulsion splash everywhere.

3, the utility model novelty simple in structure is easy to maintenance.

Description of drawings

The utility model drawings attached two width of cloth, wherein:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a perspective view of the present utility model.

Among the figure: 1, rolling door lifting gear, 2, rolling door, 3, the rolling door track, 4, cylinder, 5, quadric chain, 6, the column support, 7, the roll changing carriage trapped orbit, 8, the roll changing carriage moving track, 9, the milling train platform.

The specific embodiment

A kind of track wobble formula roller door arrangement as depicted in figs. 1 and 2 comprises rolling door lifting gear 1, rolling door 2, rolling door track 3, column support 6, cylinder 4 and quadric chain 5; Column support 6 is fixed on roll changing carriage trapped orbit 7 both sides, described rolling door lifting gear 1 is fixed on milling train platform 9 tops, two swing connecting bar one ends of quadric chain 5 and column support 6 hinged inside, the other end and rolling door track 3 are hinged, cylinder 4 respectively with milling train platform 9 bottoms and rolling door track 3 upper articulations.When mill roll, cylinder 4 rod chamber air inlets, rolling door track 3 is by the upwards swing rise counterclockwise of quadric chain 5 wraparound turning points, rolling door lifting gear 1 is rotated counterclockwise rolling door 2 and lifts, make roll changing carriage and the mutually noninterfere of milling train closed system, the slit meets design requirement in 2mm when having guaranteed rolling mill changer moving track 8 and trapped orbit 7 butt joints; Cylinder 4 rodless cavity air inlets when milling train steel rolling, track 3 falls by quadric chain 5 wraparound turning point clockwise direction lower swings, and rolling door lifting gear 1 rolling door 2 that turns clockwise is fallen, and the sealing milling train is avoided emulsion splash everywhere.

The utility model has the advantages that novelty simple in structure, handling safety.
