Self-weight electromagnetic acceleration fire-fighting cleaning through fire hook

Abstract

The invention discloses a self-weight electromagnetic acceleration fire-fighting cleaning through fire hook which comprises a casting barrel. A through hole end cover is in threaded connection with the middle position of the bottom of an inner cavity of the casting barrel, a pull bolt is movably connected to the inner surface of the through hole end cover, and a clamping piece is fixedly connectedto the middle position of the side, close to the casting barrel, of the pull bolt. A crossbow shooting mechanism is movably connected to the inner surface of the clamping piece; a chain is fixedly connected to the side, away from the pull bolt, of the clamping piece; a hook rod is fixedly connected to the end, away from the clamping piece, of the chain; an energy rod is fixedly connected to the end, away from the chain, of the hook rod; and an acceleration rod is movably connected to the side, away from the hook rod, of the energy rod. An inner cavity of the acceleration rod is movably connected with a claw mechanism; and the end, away from the energy rod, of the inner surface of the inner cavity of the acceleration rod is fixedly connected with an anti-collision protection mechanism. Theinvention relates to the technical field of fire hooks. Throwing type hooking can be conducted remotely, personnel are prevented from making close contact with a fire scene, and personal safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fire hooks, in particular to a self-weight electromagnetic accelerated fire-fighting cleaning through fire hook. Background technique [0002] Fire hooks are generally used for cleaning hooks at fire sites, breaking down ceilings, and hooking wires. The existing fire hook is formed by connecting up and down successively by multi-section split rods, wherein the top of the uppermost split rod has a hook head. The butt joints of the adjacent two sub-rods are sleeved with pipe joints, and the pipe joints and the sub-rods are connected by threads. When the two sub-rods are installed, they need to be respectively screwed into the pipe joints for effective use. [0003] According to Chinese patent CN107569789A, it includes a head rod, several intermediate rods and a tail rod. The upper end of the head rod is formed with a fulcrum, the top of the fulcrum is formed with a sharp cone, and the fulcrum is formed wit...
