Abstract

The utility model relates to a four roller working machine rollers are dismouting machine, including base, U type seat, slide rail, bearing frame, tightly deciding bolt and pneumatic cylinder, the base upper end is the work plane, and an upper end open -ended U type seat is equipped with admittedly at the middle part on the base, and this U type seat is used for clamping the middle part boss of fixing a position the roll, and two tip that the roll has the bearing all transversely stretch out outside the U type seat, equal symmetry is equipped with the horizontal slide rail that sets up of level admittedly on the base of U type seat both sides, and all the direction removes and installs a bearing frame on the slide rail of the horizontal both sides of U type seat, and radial pre -installation has a plurality of bolts of tightly deciding on the bearing frame, all install a pneumatic cylinder on the base in the horizontal outside of bearing frame. The utility model discloses effectively having alleviated the drawback of artifical dismouting bearing frame, having reached and used manpower sparingly, the assembly is accurate, not fragile work piece in addition, and advantages such as reduce cost especially adopt and replace manual work, have effectively eliminated industrial injury hidden danger.

Description

A kind of four roller working machine roller system changers

Technical field

The utility model belongs to heavy duty equipment field, especially a kind of four roller working machine roller system changers.

Background technology

At present, in most of steel mill, substantially still adopt artificial roll change, the process exception of tearing bearing block open is difficult, wastes a large amount of manpower and materials, and there is fragile workpiece and bearing in disassembly process, the situations such as assembly precision is inadequate.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of structural strength is high, shock resistance good, four roller working machine roller system changers of wear-and corrosion-resistant, long service life.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of four roller working machine roller system changers, it is characterized in that: comprise pedestal, U-shaped seat, slide rail, bearing block, tight fixed bolt and hydraulic cylinder, pedestal upper end is working face, the U-shaped seat of a upper end open is fixed with in pedestal upper center, this U-shaped seat is for clamping the middle part boss of location roll, and roll all crosses out outside U-shaped seat with two ends of bearing;

On the pedestal of U-shaped seat both sides, equal symmetry is fixed with the slide rail that horizontal cross is arranged, and on the slide rail of the both lateral sides of U-shaped seat, equal guiding movement is provided with a bearing block, and on bearing block, radial direction is preinstalled with multiple tight fixed bolt; The pedestal of bearing block lateral outer side is all provided with a hydraulic cylinder.

And the equal symmetry in pedestal upper end outside slide rail is fixed with backplate.

And hydraulic cylinder is arranged on pedestal by hinged block, by hinge hinge dress between hydraulic cylinder and bearing block.

Advantage of the present utility model and good effect are:

The utility model effectively alleviates the drawback of artificial dismounting bearing block, reaches saving manpower, and accurately, and not easily defective work piece, the advantage such as to reduce costs, especially adopt and replace manual work, effectively eliminating industrial injury hidden danger in assembling.

Detailed description of the invention

Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of four roller working machine roller system changers, comprise pedestal 8, U-shaped seat 5, slide rail 9, bearing block 2, tight fixed bolt 3 and hydraulic cylinder 1, pedestal upper end is working face, the U-shaped seat of a upper end open is fixed with in pedestal upper center, this U-shaped seat is for clamping the middle part boss of location roll 6, and roll all crosses out outside U-shaped seat with two ends of bearing 4;

The lateral dimension of U-shaped seat can regulate according to the specification of roll.

On the pedestal of U-shaped seat both sides, equal symmetry is fixed with the slide rail that horizontal cross is arranged, and on the slide rail of the both lateral sides of U-shaped seat, equal guiding movement is provided with a bearing block, and on bearing block, radial direction is preinstalled with multiple tight fixed bolt, and tight fixed bolt is used for limiting locking bearing; The pedestal of bearing block lateral outer side is all provided with a hydraulic cylinder. this Driven by Hydraulic Cylinder bearing block transverse shifting.

The equal symmetry in pedestal upper end outside slide rail is fixed with backplate 7.

In order to prevent torsion from damaging hydraulic cylinder, hydraulic cylinder is arranged on pedestal by hinged block 10, by hinge hinge dress between hydraulic cylinder and bearing block.

The course of work:

This device location is adjusted to the position of wanting dismounting roller system;

The roll lifting that will change is above equipment;

After roll is stuck on middle U-shaped seat, the holding screw at bearing block two ends is twisted firmly;

Start equipment, utilize the two ends steel plate of sliding bottom to be pulled out by bearing block.

When starting equipment, need first crawl test run, bearing block then can pull out by the situations such as non-displacement, jam, abnormal sound.

Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.

Claims

1. a roller working machine roller system changer, it is characterized in that: comprise pedestal, U-shaped seat, slide rail, bearing block, tight fixed bolt and hydraulic cylinder, pedestal upper end is working face, the U-shaped seat of a upper end open is fixed with in pedestal upper center, this U-shaped seat is for clamping the middle part boss of location roll, and roll all crosses out outside U-shaped seat with two ends of bearing;
