Description
Technical field
The utility model belongs to hot-rolled steel section Mill Technology field, is related on a kind of milling train for facilitating oil cylinder dismounting, installing
Roller owner's balancing cylinder structure.
Background technology
Milling train is most important equipment in steel and iron industry rolling system, and bascule is the important composition portion of milling train
Point, because bascule can balance the weight between upper roller system and its bearing block and pressure head, and eliminate down screw rod and pressure spiral shell
Existing gap between mother and caused enormous impact force.Because the specification pattern of milling train is different, the requirement to bascule is not yet
Equally.At present, most widely used balance mode has：Common spring balancing, counterweight balance and hydro-cushion.Heavy Plate Plant
The main bascule of milling train is often using hydro-cushion, the bascule phase of this hydraulic balance device and other forms
Than, its advantage is compact-sized, is operated steadily, easy to use, easily operated and can change oil cylinder working-pressure etc., but it there is also
Some shortcomings, i.e. Maintenance and Repair are extremely difficult.
Usually, milling train upper roller system balancing cylinder need to change cylinder seal because of bad seals oil leak or oil cylinder is repaired
During replacing, phase could be carried out to oil cylinder by being required to remove bearing pin from the connecting hole between upper roller system balancing cylinder and shoulder pole girder
The operation answered.In milling train rolling process, because bearing pin is chronically in high temperature and the environment of steam corrosion, it is difficult to protectiveness
Bearing pin is completely taken off and also expend it is substantial amounts of manually and man-hour, therefore, upper roller system balancing cylinder is carried out ninety-nine times out of a hundred
All it is that destructive cut away bearing pin can just split out bearing pin during Maintenance and Repair, and then upper roller system balancing cylinder and shoulder pole girder is divided
Leave.
Utility model content
In view of this, in order to solve in milling train rolling process, what the bearing pin of corrosion was not easy to be disassembled asks the utility model
Topic, there is provided a kind of to facilitate dismounting hinge pin, milling train upper roller owner's balancing cylinder structure of installation.
To reach above-mentioned purpose, the utility model provides following technical scheme：Including balancing cylinder, the upper end of balancing cylinder
Offer U-shaped seat on face, oil cylinder crossbeam is placed in U-shaped seat, offer shoulder pole girder hole on oil cylinder crossbeam, it is detachable in shoulder pole girder hole
Insertion bearing pin, U-shaped seat is divided into upper half circular arc U structures and lower half circular arc U structures, and lower half circular arc U structures are in semicircle knot
Structure, the diameter of lower half circular arc U structures is identical with the diameter of oil cylinder crossbeam, and the opening degree of upper half circular arc U structures is more than lower half
Circular arc U structures, for whole U-shaped seat into open-like shape, U-shaped seat both sides are provided with clamp, and fastener, lower half circular arc are provided with clamp
The bottom center of U structures offers through hole.
Further, clamp is provided with proximity switch.The proximity switch can detect the degree of closeness of clamp and bearing pin.
Further, fastener is bolt.Clamp can be fixedly mounted on cylinder by bolt.
Further, the connected mode in bearing pin and shoulder pole girder hole is the interference fits that hole axle coordinates.
Further, the size of bearing pin is φ 320mm × 700mm.
Further, through hole is tapped through hole, a diameter of 100mm of tapped through hole.
Further, the upper surface of clamp is carburized layer.
Compared with prior art, its advantage is the utility model：
1st, the lower half circular arc U structures of U-shaped seat are direct identical with oil cylinder crossbeam on milling train upper roller owner's balancing cylinder,
Oil cylinder crossbeam can be caused to be stuck on balancing cylinder, bear about 500T roller system weight, oil cylinder crossbeam will not be on balancing cylinder
Rock, influence the steel rolling effect of whole milling train；The effect of upper half circular arc U structures is that the bearing pin being inserted on shoulder pole girder is led
To so that bearing pin is accurately inserted on shoulder pole girder, and so, shoulder pole girder and bearing pin are directly fallen in as an entirety after improving
On the U-shaped seat of balancing cylinder.After the clamp of U-shaped seat both sides clamps bearing pin, clamp is fixed on balance cylinder by bolt, this
Sample, when balancing cylinder repairs, the bolt opened on clamp is turned on, clamp is removed, the overall structure that shoulder pole girder and bearing pin are formed
With regard to can be separated with balancing cylinder, facilitate the maintenance of balancing cylinder.
2nd, by the improvement to milling train upper roller system conventional balanced cylinder structure, and by later stage prolonged production run with
And Maintenance and Repair facts have proved：The Maintenance and Repair efficiency of milling train upper roller system balancing cylinder after improvement improves nearly 7 times, whole flat
Balance system operating cost also largely reduces, and the security and stability of system operation also has no difference compared with before-improvement, and necessarily
The production efficiency of heavy and medium plate mill is also improved in degree.Therefore, the technology can maturely promote the use of milling train system of steel mill
Unite in the improvement of main balancing cylinder.
3rd, U-shaped seat bottom opens up tapped through hole, by inserting suitable jackscrew, the continuous rotation of jackscrew in tapped through hole
Enter, enable to bearing pin constantly to be lifted, it helps shoulder pole girder and bearing pin separate with balance cylinder, facilitate the dimension of balance cylinder
Repair.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
Accompanying drawing illustrates：
Fig. 1 is the structural representation of the utility model milling train upper roller owner's balancing cylinder structure；

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Reference in Figure of description includes：
Balancing cylinder 11, oil cylinder crossbeam 12, bearing pin 13, clamp 14, fastener 15, through hole 16, U-shaped seat 17.
A kind of milling train upper roller owner balancing cylinder structure as depicted in figs. 1 and 2, the upper surface of rectangle balancing cylinder 11 is opened
If U-shaped seat 17, it is in semicircle knot that U-shaped seat 17, which divides for upper half circular arc U structures and lower half circular arc U structures, lower half circular arc U structures,
Structure, the diameter of lower half circular arc U structures is identical with the diameter of oil cylinder crossbeam 12, under the opening degrees of upper half circular arc U structures is more than
Semicircular arc U structures so that whole U-shaped seat 17 is into open-like shape.
Oil cylinder crossbeam 12 is placed in U-shaped seat 17, opens up shoulder pole girder hole on oil cylinder crossbeam 12, shoulder pole girder hole it is a diameter of
320mm, dismountable insertion bearing pin 13 in shoulder pole girder hole, the size of bearing pin 13 are φ 320mm × 700mm, and bearing pin 13 with it is flat
