SU1206593A1 - Arrangement for replacing support rollers in heating furnaces - Google Patents

Description

The invention relates to the technique of replacing rollers in heating furnaces without stopping the technological process and can be used when replacing rollers in heating furnaces of metallurgical and small-scale factories .;

The aim of the invention is to reduce the cost of the process of replacing the rollers by reducing the intensity of use of the lifting equipment of the workshop, for example, overhead cranes.

Reduction of energy consumption is also possible when the hanging mechanism is suspended, as a result of which it is possible to free shop areas and use them more rationally when placing Equipment in the workshop. In addition, it is possible to use the proposed device for roller furnaces with different height of roller installation — from the floor level of the workshop.

FIG. 1 shows the proposed device in its initial position with a replaceable roller, general view ;, in FIG. 2 - the same, in the position of full operation of the pressing mechanism, i.e. partial extraction of the roller; Fig. 3 - the same, with the complete extraction of the replaceable roller.

The device consists of Guides I, a carriage 2, a cantilever beam 3 on which a carriage 4 is mounted movably with a movably fixed on it, a gripper 5 and a pneumatic cylinder 6. The transshipment stand is equipped with a 4-position tipper, a supporting roller 8 with reels .: The device also contains a pressing mechanism 9, which is located on the drura side of the furnace, containing a platform 10, which carries on itself a movably fixed pneumocillium 11 and a rod 12.

The device works in the following way.

Trolley 2 with prepared replacements with their rollers is fed along rails (guides 1) laid along the furnace and mounted against a replaceable roller. The carriage 4 with claws 5 is guided through the cantilever beam 3 to the roller trunnion, the pneumatic cylinder 6 is turned on, and the gripper 5 locks the axle of the roller to be replaced along the outer diameter. Simultaneously, from the back side of the furnace, the rod 12 is set against the roller to be replaced, and the pneumatic cylinder 11 presses the rod 12, inserting it into the trunnion socket of the replaceable roller. Then, the stroke of the carriage 4 is engaged with a gripper 5 for removing the roller. At this stage, the rod 12 of the pressing mechanism 9, pressed by the pneumatic cylinder 11, also moves, accompanying the replacement of its roller, being its second support (the first is gripper 5J. The pressing of the pressing mechanism 9 is sufficient with the input of the barrel of the replaceable roller to the supporting roller 8. Thus, the replaceable roller again receives two points of support — roller 8 and grip 5 and is completely removed from the furnace. The replaceable roller is skidded by trolley 7 onto the trolley. Lift roller 7, which has a four-position drum design, simultaneously gives out Rolls to the initial position of the roller installation.

The replacement roller is installed in the reverse order.

After replacing one roller, the device moves to a new position along the rails laid along the heel. The proposed device allows the rollers to be replaced in all roller-type heating furnaces without destroying the lining. Replacing the rollers is accompanied by a decrease in the cost of the process. - I
