A rotary lifting device for repairing coke oven door

Abstract

The invention discloses a rotary lifting device for repairing a coke oven door. The rotary lifting device comprises a main frame, a docking mechanism, a rotating mechanism, a lifting mechanism, a traveling mechanism and a control system, wherein the docking mechanism and the rotating mechanism are arranged on the main frame; the main frame is connected with the traveling mechanism by virtue of the lifting mechanism; the traveling mechanism can move along a ground guide rail; and the control system controls each mechanism to finish the actions such as docking and clamping, rotating, lifting, elevating and traveling of a traveling trolley on the coke oven door. Compared with the prior art, the rotary lifting device disclosed by the invention has the beneficial effects that 1) the device is suitable for two different bolt structures of a pressing mode and a rotating mode; 2) a main frame of a single-side frame structure is adopted, each part of the oven door is convenient to maintain, and the maintenance efficiency is high; 3) the operation is stable and reliable; 4) the lifting action is realized by virtue of retraction and rotation of a folding arm, and the operation is stable and reliable; 5) the left and right folding arms synchronously retract, so that the oven door is lifted to a proper height, and the working conditions are improved; and 6) a set of device can be shared on the machine and coke side, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of special equipment for repairing coke oven doors in the coking industry, in particular to a rotary lifting device for repairing coke oven doors. 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 furnace door is taken off from the carbonization chamber and sent to the furnace door repair station. The coke oven vehicle hangs the furnace door on the landing gear of the rotary landing gear, and then the furnace door completes the lifting and rotating movements together with the landing gear before entering Maintenance station. In order to realize landing and rotation, there are usually the following two methods: [0003] One is to slide the undercarriage together with the furnace door from the vertical state slowly along the slide rails to the horizontal state, with the l...

Problems solved by technology

In addition, in order to complete the lifting and lowering action, the method of hoist traction combined with wire rope pulley block transmission or sprocket chain drive combined with arc guide rail sliding requires a set of indomitable steel structure slide rails and landing gear on both sides of the coke oven machine and coke. , and the height of the landing gear cannot be adjusted when it is in a horizontal state, so that the operating height of the workers when repairing the furnace door cannot be adjusted according to the different maintenance parts

Therefore, the above two methods all have the disadvantages of unreasonable structure, low maintenance efficiency, labor-intensive and time-consuming, and unsatisfactory use effects.
