Summary of the invention
Proposition of the present utility model is intended to change the installation site of lifting mechanism accident brake, and it is simple to reach safety control, impact under the emergency braking situation little, purpose such as cost is low.
Technical solution of the present utility model is achieved in that
A kind of hoisting crane lifting mechanism of planetary transmission, comprise electric motor I and electric motor I I, service brake I and service brake II, accident brake, planetary reduction gear, the reel group, fixed pulley group and steel rope, fixed pulley group wherein, running block on reel group and steel rope and the suspender constitutes steel rope rope system, electric motor I, II links by coupler and retarder, retarder is by drum coupling and reel set associative, electric motor I, II drives retarder and drives steel rope rope system and lifting mechanism lifting, it is characterized in that: electric motor I drives sun wheel, external toothing in electric motor I I drives, service brake I, II is contained in respectively on described two motor reels; Accident brake then links by a pair of multiplying wheel and pinion carrier and/or is set directly on the pinion carrier axle.
Compared with prior art, advantage of the present utility model mainly shows:
1, can cancel monitored control system, make the control of lifting mechanism simple, reduce maintenance levels requirement, cost-cutting the user.
2, the braking safety to lifted load is higher than employing fixed shaft gear train spur gear drive.
3, accident brake is arranged on the gear wheel shaft that links with pinion carrier or with accident brake and is set directly on the pinion carrier axle, and moment is little, greatly alleviated the impact to complete machine during misoperation, and the accident brake specification is little, and cost is low.

Fig. 2 is the lifting mechanism scheme drawing on the gear wheel shaft that links of accident brake setting of the present utility model and pinion carrier;
Fig. 3 is a planetary reduction gear structural representation of the present utility model;
Fig. 4 is existing planetary reduction gear formula lifting mechanism scheme drawing.
In the drawings: 1.1 electric motor I, 1.2, electric motor I I, 2.1, service brake I, 2.2, service brake II, 3, the fixed pulley group, 4, the reel group, 5, steel rope, 6, accident brake, 7, planet bag retarder, 7.1 pinion carrier, 7.2 sun wheel, 7.3 satellite gears, 7.4, in (outward) gear ring 8, monitored control system, 9, multiplying wheel.
The specific embodiment
As Fig. 1～a kind of hoisting crane shown in Figure 3 lifting mechanism of planetary transmission, by electric motor I 1.1, electric motor I I 1.2, service brake I 2.1, service brake II 2.2,, an accident brake 6, the retarder 7 of a band planet bag, 3, two steel ropes of 4, one fixed pulley groups of a reel group, 5 compositions such as grade.Running block on reel group 4, fixed pulley group 3, steel rope 5 and the suspension hook group (or suspender) is formed steel rope rope system.Electric motor I, electric motor I I link by coupler and retarder 7, and reel group 4 links by drum coupling and retarder 7.Electrical motor 1 drives retarder 7, and retarder 7 drives steel rope rope system, and drives lifting mechanism hook group (or suspender) lifting, it is characterized in that: electric motor I 1.1 drives sun wheel 7.2, external toothing 7.4 in electric motor I I1.2 drives.Two service brake I, II are contained in respectively on two motor reels, and control the motion of sun wheel 7.2, internally toothed annulus 7.4 respectively.Accident brake 6 links with pinion carrier by a pair of multiplying wheel 9 or accident brake 6 is set directly on the pinion carrier axle.The accident brake lock torque is little like this, has greatly alleviated the impact to car load during misoperation; The accident brake specification is little, and cost is low.
During the lifting mechanism normal operation, two electrical motors turn round simultaneously.The rotating speed of electric motor I and electric motor I I passes to retarder 7 output shafts with power by pinion carrier, cylindrical wheel in the stack of pinion carrier place, thereby the rope that drives reel group 4, fixed pulley group 3, steel rope 5 compositions is with specified lifting velocity v
eLong-term work.
When electric motor I breaks down, service brake 2 brakings on it, electric motor I I drives internally toothed annulus, and internally toothed annulus drives satellite gear, and satellite gear drives pinion carrier, and pinion carrier is given retarder 7 output shafts with transmission of power, and lifting mechanism is pressed lifting velocity v
1Normal operation; When electric motor I I breaks down, service brake 2 brakings on it, electric motor I drives sun wheel, and sun wheel drives satellite gear, and satellite gear drives pinion carrier, and pinion carrier is given retarder 7 output shafts with transmission of power, and lifting mechanism is pressed lifting velocity v
2Normal operation.The relation of above-mentioned three lifting velocities is: v
e=v
1+ v
2
No matter lifting mechanism is by above-mentioned which lifting velocity operation, and the transmitting ratio i between pinion carrier and the speed reducer output shaft is a definite value, and i is much larger than 1.Simultaneously, because the messenger chain between pinion carrier and the speed reducer output shaft is the fixed shaft gear train spur gear drive, so accident brake be arranged on the pinion carrier axle or be arranged on the gear wheel shaft that links with pinion carrier, required lock torque is much smaller than accident brake being arranged on the required lock torque of low speed end (reel place), and the safety of lifted load braking is compared with accident brake being arranged on low speed end (reel place), significantly do not reduce.
