AI Technical Summary
The opening and closing of the slag simmering tank cover poses safety hazards and operational instability, especially the risk of falling due to breakage or detachment of the winch wire rope, and the operation is cumbersome, affecting work efficiency.
The design combines mechanical fall protection with counterweight balance. It uses a protective frame, pulley system and free counterweight block to achieve fall protection with electro-hydraulic push rod pin. The guide rail and pulley system stabilize the lifting and lowering, reducing the load fluctuation of the winch.
It achieves safe anti-fall and stable lifting of the slag-curing tank cover, simplifies the operation process, improves work efficiency, and enhances safety and stability.

Abstract
Claims
1. A slag pot cover switch safety protection device, comprising a slag pot, a slag pot cover (1) is arranged on the slag pot, characterized in that: The slag simmering tank cover (1) is equipped with a switch pulley 1 (2) and a protective pulley 1 (3) on the top of the cover; a protective frame (4) is provided. The protective frame (4) is a multi-layer structure. The lower layer is equipped with a switch pulley 2 (5), and the upper layer is equipped with a protective pulley 2 (6) and a protective pulley 3 (7). The cable entry method of the switch pulley group is that one end of the wire rope is fixed on the lower layer of the protective frame (4), and the other end goes around the protective pulley 1 (3) and then around to the protective pulley 2 (6) and turns to connect to the winch (8) below. The cable entry method of the protective pulley group is that one end of the wire rope is fixed on the upper layer of the protective frame (4), and the other end goes around the protective pulley 1 (3) and then around to the protective pulley 2 (6) and the protective pulley 3 (7) and turns to connect to the free counterweight (9).
2. A slag pit cover switch safety guard according to claim 1, characterised in that: The protective frame (4) is a double-layer frame structure. The main body consists of four columns, on which two layers of flat plates are mounted. Three pulleys are on the same cut surface.
3. A pit cover switch safety guard for a pit according to claim 2, wherein: The protective frame (4) has two vertical guide rails on its side. The inner side of the two guide rails is welded with a connecting surface. The connecting surface and the two guide rails together form a groove for the free counterweight (9) to slide.
4. The slag pocket cover switch safety guard of claim 1, wherein: The bottom of the free counterweight (9) is provided with a U-shaped clamp for locking. The bottom of the protective frame (4) is provided with a locking groove that matches the free counterweight (9). A push rod pin is provided next to the locking groove. When the push rod pin extends and passes through the U-shaped clamp, locking is achieved.
5. A pit cover switch safety guard for a pit according to claim 4, wherein: The push rod in the push rod pin is a hydraulic or electric telescopic rod.
6. A slag bin cover switch safety guard according to claim 1, wherein: The mass of the free counterweight (9) is 30%-50% of the mass of the slag tank cover (1).
