Through adopting above-mentioned technical scheme, when electric block used, the motor at casing both ends started, drives the reel through reduction gear and shaft coupling and rotates to make the reel unreel or wind the book to the chain. And after the lifting hook moves to a proper position, starting a brake to stop the driving of the motor so as to stop the rotation of the winding drum, so that the moving lifting hook is fixed. Through adopting double dynamical drive, when the condition that the reduction gear appears in the electric block, the transmission shaft breaks, the moment of braking can convey above the reel, effectively prevents the emergence of incident, in time discovers corresponding trouble.

When the chain is wound, the driving assembly is started to drive the hinged plate to rotate around the hinged column so as to enable the hinged plate to rotate upwards, the sliding block on the hinged plate is enabled to abut against the chain and then slide towards the hinged column, and meanwhile, the winding drum winds the chain so as to enable the chain to be gradually wound around the whole winding drum after being abutted against the sliding block when the chain is wound; when the chain is unreeled, the driving assembly is started to drive the hinged plate to rotate downwards around the hinged column, so that the sliding block on the hinged plate slides in the direction away from the hinged column after being separated from the chain, and the chain is automatically unreeled under the rotation of the winding drum. Thereby making the reel atress more even, reducing the damage that the reel received to increase the life of reel.

Optionally, the driving assembly comprises a driving rod sliding in the casing along the vertical direction, and a driving part arranged on the winding drum and connected with the driving rod, the driving part is used for driving the driving rod to slide through the rotation of the winding drum, the hinged plate is provided with a through hole for the driving rod to pass through, one end of the driving rod passing through the through hole is provided with an abutting block abutting against the bottom wall of the hinged plate, and the driving rod swings in the through hole.

Through adopting above-mentioned technical scheme, when coiling the chain, the reel rotates and winds the chain, and the reel drives the actuating lever through the driving medium simultaneously and upwards slides, until butt piece butt in the diapire of articulated slab to make the articulated slab receive and upwards rotate around the hinge post after the butt of butt piece, and then make the slider on the articulated slab butt chain towards the hinge post slip. When unreeling the chain, the reel rotates and unreels the chain, and the reel drives the actuating lever lapse through the driving medium simultaneously to make the butt piece break away from the articulated slab, make the articulated slab rotate downwards around the hinge post, and then make the slider break away from the chain on the articulated slab and slide towards the actuating lever. Therefore, by arranging the driving rod, the driving rod is driven by the rotation of the winding drum to slide up and down by the transmission piece, the sliding block slides on the hinged plate after rotating, and the butt chain is wound or unwound along the length direction of the winding drum, so that the hinged plate is driven to rotate conveniently.

Optionally, the transmission part comprises a rack arranged on the side wall of the driving rod and a gear meshed with the rack, one end of the winding drum, which is far away from the hinge column, is coaxially connected with a rotating shaft, and the gear is coaxially connected with the rotating shaft.

Through adopting above-mentioned technical scheme, when the reel rotates and drives the actuating lever and slide, the reel drives the pivot and rotates, and the pivot drives gear revolve, and the gear drives the rack and slides from top to bottom, and then drives the actuating lever and slides from top to bottom to make gliding actuating lever drive the articulated slab and rotate round the hinge post. Therefore, the rack and the gear are arranged, the rotation of the winding drum is transmitted to the driving rod and used as a power source for the sliding of the driving rod, and therefore the driving rod can slide up and down conveniently.
