The invention discloses a small hoisting mechanism. The small hoisting mechanism comprises a hoisting hook, a connecting hook shaft, a pulley group, an overload limiter, steel wire ropes, brake motors, rope reels, a hoister inner cavity, rotary shafts, a power-assisted stretcher, an outer-layer rope reel, a power supply switch, a variable-frequency motor, a shaft coupling and a reinforcing rib, wherein the hoisting hook is installed at the bottom of the connecting hook shaft, and the top end of the connecting hook shaft is connected with the pulley group; the overload limiter is fixedly connected with the reinforcing rib; the two steel wire ropes are arranged at an upper left end and an upper right end; one rope reel is fixed at the periphery of each brake motor and is connected with the corresponding rotary shaft; the power-assisted stretcher is fixedly installed at the centre of the hoister inner cavity; the outer-layer rope reel is fixedly connected with the shaft coupling; the power supply switch communicates with the variable-frequency motor; and the reinforcing rib is connected with the outer-layer rope reel. The small hoisting mechanism is simple in structure, and capable of being used for a hoisting machine, slowing down a speed stage by stage, and hoisting a heavy object by a small power. The small hoisting mechanism is good in brake effect, and convenient for overhaul personnel to overhaul up and down, thus the working efficiency is greatly increased.
Description
Technical field
The present invention relates to one hoist field, a kind of small-sized lifting mechanism.
Background technology
Lifting mechanism, lives as modern industry and people and applies extremely widespread jack up unit, the most raw in producing
The irreplaceable role of performer in producing in work.Lifting mechanism is the pith of crane, generally includes reel, change speed gear box
And motor.The output shaft of motor matches with the gear in change speed gear box.By the conduction of change speed gear box, motor output torque is sent to
Reel, thus drive spool turns, provide pulling force to the lifting rope being wound on reel.During the use of crane, need really
Protect lifting rope to collide with the equipment such as motor, rub.
But, the design of existing lifting mechanism result road is unreasonable, and existing lifting mechanism reel has motor to drive, motor
Arranging brake between power transmission shaft and reel, owing to being only provided with a brake, therefore its braking effect is not fine, if
Lifting mechanism is braked the most in time, on-the-spot staff may cause threat design size for security relatively big, make
Occupying larger space in, lifting mechanism itself has bigger quality, uses operation extremely inconvenience.
Summary of the invention
It is an object of the invention to provide a kind of small-sized lifting mechanism, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of small-sized lifting mechanism, including suspension hook, even hook
Axle, assembly pulley, load limiter, steel wire rope, braking motor, rope drum, lifting machine inner chamber, rotary shaft, power-assisted stretcher, outer layer
Rope drum, on and off switch, adjustable frequency motor, shaft joint and reinforcement, be mounted with suspension hook bottom described even hook axle, and top and cunning
Wheels connect, and described load limiter is fixing with reinforcement to be connected, and upper end, left and right is provided with at steel wire rope two, described braking electricity
Machine periphery is fixed with rope drum, and is connected with rotary shaft, described lifting machine lumen centers fixed in position power-assisted stretcher, described outside
Layer rope drum is fixing with shaft joint to be connected, and described on and off switch connects with adjustable frequency motor, described reinforcement and outer layer rope drum
Connect.
Preferably, it is embedded with groove bottom described even hook axle, and it matches with suspension hook.
Preferably, described braking motor is provided with at two, and symmetrical placement around.
Preferably, described power-assisted stretcher is arranged on the surface of power-assisted stretcher, and on same vertical curve.
Preferably, described adjustable frequency motor left end is mounted with shaft joint, and it is Frequency Adjustable device.
Compared with prior art, the invention has the beneficial effects as follows: this small-sized lifting mechanism is the most fairly simple, available
In hoisting machinery, reducing speed step by step, with less power lifting heavy.And speed is easily controlled, it is also possible to prevent reel
Reversing, steel wire rope has two, and after wherein steel cable ruptures, another steel cable can work on, and adds handling
The safety coefficient of journey, it is to avoid pendant formal matter event, arranges two brakes, good braking effect simultaneously, and security performance is good, it is simple to maintenance people
Member overhauls up and down, substantially increases work efficiency.
