Description
Technical Field
The utility model relates to an overhaul platform safety control mechanism specifically is a safety control mechanism that mine well head overhauld platform suitable for mine well head overhauls, belongs to mining equipment technical field.
Background
Mine hoisting refers to transporting out ore, coal, waste rock or gangue along a mine shaft, and lifting personnel, equipment and the like. Mine hoisting is most widely used as wire rope hoisting. With the development of the coal industry in China, the lifting of the auxiliary vertical shaft of the mine gradually develops towards the deep and heavy direction, namely the lifting depth exceeds 800 meters, and the lifting total weight exceeds 80 tons. In order to ensure safe production of a mine, a hoisting steel wire rope, a skip and a cage serving as a hoisting container need to be overhauled and maintained regularly so as to eliminate potential safety hazards.
The maintenance of skip, cage and hoisting wire rope is usually carried out at the vertical well head, owing to limited by the special environmental condition of vertical, overhauls the maintenance during operation and need erect maintenance platform so that overhaul maintenance personnel overhauld and maintain the work at vertical well head position. The traditional maintenance platform is characterized in that after an I-shaped beam is erected on a well head, plates are laid on the I-shaped beam to form a platform structure, the temporarily constructed maintenance platform is slow in construction, time-consuming and labor-consuming, easy to move and unstable, and has great potential safety hazards when being stood on the platform for maintenance operation.
Aiming at the problems, the prior art has a single-open or split type mine wellhead overhaul platform with a table top capable of being opened or closed in a turnover mode, the table top is completely turned over and opened within the range of 0-90 degrees and is in a vertical state, the lifting container is not influenced to pass through the mine wellhead overhaul platform to go into the well when being turned over and opened within the range of 0-90 degrees, and the table top can form a platform structure when being completely turned over and closed within the range of 0-90 degrees and is in a horizontal state, so that overhaul personnel can stand on the platform to lift a steel wire rope or the lifting container. When the table top is completely turned over and closed to be in a horizontal state, enough supporting strength and stable supporting effect need to be ensured, and particularly, aiming at an opposite-opening mine wellhead maintenance platform, the table top needs to be limited to be turned over continuously within the range of 0-90 degrees, so that safety accidents are caused. The limiting block or the limiting plate structure which is protruded and fixed on the table top is adopted to limit the table top in the prior art, the protruded structure is easy to cause stumbling of maintainers, and only has a limiting function and does not have a locking function.
