Abstract
The utility model discloses a kind of rolling finishing mill roll shifting sliding block anti-drop devices, including one end to be fixedly installed in the L-type plate hook in rolling-mill housing, and the strip groove being set on play upper end of slide block side wall；The hook plate of L-type plate hook lower end is located in the strip groove, and the hook plate is slidably matched with the strip groove.The rolling finishing mill roll shifting sliding block anti-drop device of this practicality, the play sliding block that can effectively avoid hot-rolling finishing mill slide down accident, to ensure steady production, improve production efficiency.
Description
Technical field
The utility model is related to a kind of rolling finishing mill roll shifting sliding block anti-drop devices.
Background technology
Working roll roll shifting be exactly working roll in the axial direction on move horizontally, the roll shifting of working roll is uniform operational roller mill
The advantageous measure of damage, at the same to improve roller the effect of, reduce working roll excessive deflection and reduce harmful contact area have centainly
Effect.The roll shifting of working roll is controlled there are four hydraulic cylinder, be respectively distributed to upper working rolls and lower working rolls fore side entrance side and
Outlet side, there are one position sensors on each hydraulic cylinder, and by the play position of sensor detecting work roller, hydraulic cylinder is logical
It crosses play sliding block and drives working roll axial float.Play sliding block play in the track of rolling-mill housing by the ears or side handles of a utensil of lower part, with
The increasing of abrasion, play sliding block can slide down phenomenon, influence production efficiency, increase maintenance amount.
Utility model content
In order to solve the above-mentioned technical problem, this practicality provides a kind of rolling finishing mill roll shifting sliding block anti-drop device, can have
Effect avoids the play sliding block of hot-rolling finishing mill from sliding down accident, to ensure steady production, improves production efficiency.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of rolling finishing mill roll shifting sliding block anti-drop device, including：
One end is fixedly installed in the L-type plate hook in rolling-mill housing, and
The strip groove being set on play upper end of slide block side wall；
The hook plate of L-type plate hook lower end is located in the strip groove, and the hook plate is slided with the strip groove
Cooperation.
Further, the outer surface of the vertical plate of the L-type plate hook is aligned with the lateral wall of the play sliding block.
Further, the hook plate of the L-type plate hook is made of High Strength Wear-Resistance Material.
Further, the L-type plate hook is made of High Strength Wear-Resistance Material.
Further, the L-type plate hook is an integral molding structure.
Further, it is provided with collision chock in the both ends in the strip groove.
Further, the length of the strip groove is more than the maximum travel limit of the play sliding block.
Compared with prior art, the advantageous effects of the utility model：
Rolling-mill housing hooks the strip groove on play sliding block by L-type plate hook, to fix play sliding block, avoids
Play sliding block slides down, and to reduce accident, ensures steady production.

Specific implementation mode
As illustrated in fig. 1 and 2, a kind of rolling finishing mill roll shifting sliding block anti-drop device, including：
One end is fixedly installed in the L-type plate hook 2 in rolling-mill housing 1, and
The strip groove 4 being set on 3 upper end side wall of play sliding block；
The hook plate 201 of 2 lower end of L-type plate hook is located in the strip groove 4, the hook plate 201 and the bar shaped
Groove 4 is slidably matched.
In the present embodiment, the outer surface of the vertical plate of the L-type plate hook 2 is aligned (position with the lateral wall of the play sliding block 3
In same plane), the hook plate 201 of the L-type plate hook 2 is made of High Strength Wear-Resistance Material, and L-type plate hook 2 is welding at this time
Separate structure or the L-type plate hook 2 are made of High Strength Wear-Resistance Material, and the L-type plate hook 2 is integrally formed knot at this time
Structure, the length of the strip groove 4 are more than the maximum travel limit of the play sliding block 3.
In another embodiment, collision chock 5 is provided in the both ends in the strip groove 4.
The utility model makes in the even slag finishing mill course of work, and rolling-mill housing 1 is hooked by L-type plate hook 2 on play sliding block 4
Strip groove 4 avoid sliding down for play sliding block 3 to fix play sliding block 3, to reduce accident, ensure steady
Fixed production.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are new to this practicality
The various modifications and improvement that the technical solution of type is made should all fall into the protection domain of the utility model claims book determination
It is interior.
