Abstract
The utility model discloses a small lift which is composed of a left and a right brackets, a drum, a steel wire rope and a brake motor. The drum is movably mounted on the left and the right brackets through bearings, and the brake motor is fixed on the right bracket. The utility model is characterized in that the output shaft of a motor is connected with an eccentric shaft through transmission; a balancing block and a planetary wheel are arranged on the eccentric shaft, and the planetary wheel is engaged with an inner gear which is fixed in the drum; a fixed shaft which is fixed on the left bracket is in rotary match with the extending end of the eccentric shaft, and the shaft is connected with the planetary wheel by a cross shaft coupler; a speed reducing mechanism with small teeth difference, which is composed of the components is entirely arranged in the inner cavity of the drum. The utility model which adopts a single-phase electric source has the advantages of big transmission ratio, simple structure, low noise and low price.
Description
The utility model relates to lifting means, particularly miniature gig.
Promoted the building whim lifting weight at least more than 500kg in the past, just do not have and hoisting capacity is specifications such as 100kg, 150kg, 200kg, 250kg, 300kg.Because when vast rural urbanization build labourer used the room construction 3-5 layer resident, building materialss such as lifting brick and sandstone cement plaster were sought after the lifting means of above-mentioned five kinds of specifications.The Guangdong flat engineering facility of Nanhai County fringe factory once produced miniature winch, but this machine speed reduction gearing still adopts three grades of helical gear reducers, rather than few tooth difference structure, the complete machine layout is to be the center with the reel, left end configuration retarder, right-hand member arrangement brake motor, be actually old-fashioned electric block structure, volume is big, complex structure, the fault rate height, the price height.
The purpose of this utility model provides and adopts small Tooth Number Difference Planetary Transmission to form speed reduction gearing to be installed in miniature gig in the reel, and transmitting ratio is big, simple in structure, in light weight, noise is low, cheap, and operating maintenance is convenient.
The utility model is finished as follows: by left socle, reel, right support, steel rope, on the gig that braking motor is formed, reel is movably arranged on the support of the left and right sides by bearing, braking motor is fixedly mounted on the right support, with motor output shaft and eccentric shaft driving coupling, balance block is installed on the eccentric shaft, satellite gear also is installed on eccentric shaft, satellite gear be fixed on reel in-to-in inner gear engagement, anchor shaft is fixedly mounted on the left socle, at the end face inner chamber of anchor shaft bearing being installed cooperates with the external part of eccentric shaft, have cross coupler to connect between anchor shaft and eccentric shaft, above-mentioned each parts are formed the inner chamber of few tooth difference speed reducing mechanism integral installation at reel.
Said inner gear and satellite gear are few tooth difference structures.
The utility model has following advantage than conventional art: 1, with the electric winch of common epicyclic gear transmission relatively under the condition of transmitting identical torque, transmitting ratio is big, and is simple in structure, compact, in light weight, noise is low, price is honest and clean; 2, can be widely used in the rural urbanization building ground, also be applicable to the vertical-lift of factory, warehouse material; 3, this machine adopts 220 volts of domestic power supplies, and is easy to install; Braking is rapid, safe and reliable during outage.
Further describe below in conjunction with accompanying drawing.
Fig. 1 is the utility model general assembly front view.
With reference to Fig. 1 is miniature gig general assembly front view, is made up of left socle (1), reel (4), right support (9), steel rope (10), braking motor (11).Reel (4) is movably arranged on the support of the left and right sides by bearing, with motor (11) output shaft and eccentric shaft (7) driving coupling, eccentric shaft (7) is gone up balance block (8) is installed, and the effect of balance block (8) is exactly when rotating and eccentric shaft (7) produces equilibrium activity.Satellite gear (6) is installed on eccentric shaft (7), satellite gear (6) again be fixed on reel (4) in-to-in inner gear (5) engagement.On the coaxial direction of eccentric shaft (7), anchor shaft (2) is fixedly mounted on the left socle (1), at the end face inner chamber of anchor shaft (2) bearing is installed and cooperates with the external part of eccentric shaft (7).Have cross coupler (3) to connect between anchor shaft (2) and eccentric shaft (7), above-mentioned each parts are formed the inner chamber of few tooth difference speed reducing mechanism integral installation in reel (4).
Here satellite gear (6) and inner gear (5) engagement for few tooth difference structure, are made deceleration transmission.Between anchor shaft (2) and eccentric shaft (7), adopt cross coupler (3), simple in structure and can compensate the assembling or the caused error of part deformation.On reel (4), be wound with steel rope (10).Complete machine weight is less than 30kg, therefore carries very convenient.Simultaneously because the lifting specification is equipped with the plurality of specifications less than 500kg, therefore can be widely used in rural urbanization when building alto building as the usefulness that promotes building materialss such as brick and tile sandstone cement wash.During work, lifting brake motor output moment of rotation drives eccentric shaft (7), slow down through the few tooth difference structure of satellite gear (6) and inner gear (5), drive reel (4), then steel rope (10) the traction rolling on the reel (4) obtains reciprocal lifting travel.Quit work, then braking motor (11) is braked immediately, has made weight stop motion immediately.
Claims (2)
1, miniature gig, form by left socle (1), reel (4), right support (9), steel rope (10), braking motor (11), reel (4) is movably arranged on the support of the left and right sides by bearing, braking motor (11) is fixedly mounted on the right support (9), it is characterized in that motor (11) output shaft and eccentric shaft (7) driving coupling, balance block (8) is installed on the eccentric shaft (7), satellite gear (6) is installed on eccentric shaft (7), satellite gear (6) be fixed on reel (4) in-to-in inner gear (5) engagement; Anchor shaft (2) is fixedly mounted on the left socle (1), at the end face inner chamber of anchor shaft (2) bearing being installed cooperates with eccentric shaft (7) external part, have cross coupler (3) to connect between anchor shaft (2) and eccentric shaft (7), above-mentioned each parts are formed the inner chamber of few tooth difference speed reducing mechanism integral installation in reel (4).
2,, it is characterized in that said inner gear (5) and row gear (6) are few tooth difference structures according to the said miniature gig of claim 1.
