Abstract

The utility model discloses a portable small-sized hoisting machine which is composed of a worm and gear driver, a pinion, a spool, a steel cable, a hook, etc., wherein, the components are all arranged in a bracket. The worm and gear driver with a large drive ratio is used, and the components are connected by screw threads, so that the utility model has the advantages of simple structure, easy assembly, and convenient carrying and use. The utility model is suitable for outgoing repair persons or repairing and hoisting in narrow places, and is especially suitable for repairing and installing an engine gearbox of a minicar outside a driving cab.

Description

Portable small-sized hoisting machine

The utility model provides a kind of portable small-sized hoisting machine, belongs to repairing, Lifting implements is installed.

Present hoisting machine tool is all thicker, heavy, being mainly used in engineering construction, installation, transportation, harbour etc. locates, as tower crane, vapour hang, hand removes cucurbit etc., to being suitable for local narrow repairing, the small-sized Lifting implements of installing and using, also do not have through the market research and the Searches of Patent Literature.

The purpose of this utility model is: provide a kind of and carry, use easy to operate, be suitable for local narrow repairing, the hoisting machine tool of installation.

The purpose of this utility model is achieved in that in the rectangular support frame that is made of angle bar, screw nut by small-sized hand hoisting device of bearing fixing, hoisting device forms by a small-sized worm and gear driver and by its internal gear binding tooth axle, fix a flute profile bobbin that steel rope and drop hanger are housed on the tooth axle, be provided with below the support can demolition, installation supporting leg, crank drives the tooth axle by worm screw and internal gear and the flute profile bobbin is done the break-in rotation, make steel rope and drop hanger do upper and lower motion, reach the purpose of the lifting of rising and falling.

Owing to adopted above-mentioned technical scheme, the utility model is simple in structure, and very big transmitting ratio is arranged, dismounting, use, easy to carry, be well suited for going out treatment people in narrow place use, be particularly suitable for mid-get car in the repairing lifting of operator's compartment to engine mission.
