A small wire rope hand electric dual-purpose hoist

Abstract

The invention discloses a small hand-operated and electric dual-purpose hoist for a steel wire rope, and the small hand-operated and electric dual-purpose hoist is used for the hoisting field. The small hand-operated and electric dual-purpose hoist comprises a housing as well as a hand-operated positive gear, an electric positive gear, a brake, a toothed long shaft, a steel wire rope coiling block, a steel wire rope, a toothed short shaft, a piece gear and a splined hole gear which are arranged inside the housing; the hand-operated positive gear and the brake are coaxially arranged on the toothed long shaft; the piece gear and the splined hole gear are coaxially arranged on the toothed short shaft; the toothed long shaft is connected with the toothed short shaft; the steel wire rope coiling block is arranged on the splined hole gear; the steel wire rope is arranged in the steel wire rope coiling block; and the electric positive gear is connected with the toothed long shaft. According to the technical scheme adopted by the invention, the small hand-operated and electric dual-purpose hoist for the steel wire rope is high in operating efficiency, is small in manual force, is light in dead weight, is beautiful in appearance, is small in size and is convenient to carry; and the hand-operated positive gear and the electric gear are arranged, so that the hoist is driven in a hand-operated mode or an electric mode; and gears are braked by ratchets and pawls, so that the gears can be braked at any position by virtue of friction plates during lowering.

Description

technical field [0001] The invention relates to a small-sized steel wire rope hand-operated electric dual-purpose hoist in the field of lifting equipment. Background technique [0002] In my country, there are two types of small manual hoists for lifting: hand chain hoists and wire rope lever hoists. As far as the hand-chain chain hoist is concerned, since the chain cannot be accommodated in the hoist, it appears to be procrastinated, the weight and volume are relatively large, and the impact sound of the chain is relatively loud during operation, so the application occasions are subject to certain limitations. The lifting or lowering conversion operation of the wire rope lever block is cumbersome: the ordinary lever block needs to be pulled to make the switch block in the "N" position, rotate counterclockwise and pull out the hand wheel, so that the clutch is in the open state, pull Use the steel wire rope to adjust the position of the lower hook; after the adjustment, tur...

As far as the hand-chain chain hoist is concerned, since the chain cannot be accommodated in the hoist, it appears to be procrastinated, the weight and volume are relatively large, and the impact sound of the chain is relatively loud during operation, so the application occasions are subject to certain limitations.

The lifting or lowering conversion operation of the wire rope lever block is cumbersome: the ordinary lever block needs to be pulled to make the switch block in the "N" position, rotate counterclockwise and pull out the hand wheel, so that the clutch is in the open state, pull Adjust the position of the lower hook with the steel wire rope; after the adjustment, turn the hand wheel clockwise to restore it to its original position, then hang the heavy object in the middle of the lower hook, and then pull the handle to lift the heavy object

The biggest disadvantage of this kind of gourd is that the lifting movement process of heavy objects is intermittent, it cannot be smooth and continuous, only the handle can be pulled once, and the object rises and falls for a certain distance, which is not suitable for objects that cannot withstand impact of
