Split type rotating lifting gear for repairing of oven door of coke oven and use method of split type rotating lifting gear

Abstract

The invention relates to a split type rotating lifting gear for repairing of an oven door of a coke oven and a use method of the split type rotating lifting gear. Two lifting racks are symmetrically mounted on a machine side and a coke side of the coke oven; a rotating mechanism is fixed on the central axes of the two lifting racks; the lifting racks are fixedly connected with the oven door through clamping mechanisms and can be driven by lifting mechanisms to rise and fall in a horizontal state or a vertical state along with the oven door; power rotating heads are arranged on two sides of the rotating mechanism and adopt a telescopic structure, the rotating mechanism drives the oven door through the power rotating heads to rotate around the horizontal axis in the connection position; the clamping mechanisms, the lifting mechanisms and the rotating mechanism are connected with a control system respectively and complete butt joint, clamping, lifting and rotation operation of the oven door under the control of the control system. The lifting gear adopts split type arrangement, the machine side and the coke side share one rotating mechanism, unilateral frame type lifting racks are adopted, encirclement and shielding of the oven door can be reduced to the largest extent, and parts of the oven door can be maintained conveniently.

Description

technical field [0001] The invention relates to an auxiliary device for repairing a coke oven door, in particular to a split rotary lifting device for repairing a coke oven door and a method for using the same. Background technique [0002] In the coke oven production process, the furnace door often needs to repair the knife edge, web, lining brick, spring and other parts. During maintenance, the coke oven vehicle hangs the furnace door on the landing gear of the rotary landing gear, and then the furnace door enters the maintenance station after completing the lifting and rotating actions together with the landing gear. In order to realize the lifting and rotating action of the furnace door, the following two methods are usually used at present: [0003] One way is to slowly slide down the undercarriage together with the furnace door from the vertical state to the horizontal state, with the lining brick of the furnace door facing up for maintenance, and then turn over the u...

Problems solved by technology

[0004] Both of the above two methods need to hang the furnace door on the undercarriage of the quadrilateral frame structure through the upper and lower door bolts. The quadrilateral frame structure surrounds and shields all parts of the furnace door seriously. Maintenance and replacement of the knife edge, web, and door It is very difficult to fasten the spring and other parts, and the furnace door can only be removed from the landing gear to an open space for maintenance

In addition, in order to complete the lifting and lowering action, it is necessary to adopt the method of winch traction combined with wire rope pulley block transmission or sprocket chain drive combined with circular arc guide rail sliding. Both sides of the coke oven machine and coke need to be equipped with a set of steel structure slide rails. It is difficult to debug and debug, the construction process is complicated, and the construction period is long

The above two methods are not ideal in practical application, so it is necessary to develop a rotary lifting device that is more suitable for repairing the coke oven door
