A kind of Novel winch
Technical field
The present invention relates to a kind of Novel winch, belong to winch drive technology field.
Background technology
The winch that domestic market uses has two kinds of forms, and one is mechanical winch, and another kind is hydraulic wireline winch; Tradition mechanical winch driving efficiency is higher, but soft-start feature and speed regulation characteristics bad, overload protection poor performance.And conventional hydraulic winch type of drive is " hydraulic power unit-HM Hydraulic Motor-load " or " hydraulic power unit-HM Hydraulic Motor-retarder-load ", easily realizes soft start, soft braking and speed-regulating function, and there is good overload protection function.But due in transmission process, energy needs multiple conversions, and efficiency is lower.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of Novel winch, not only transmission efficiency be high, reliable operation, and there is good soft-start feature and the advantage of speed regulation characteristics.
To achieve these goals, the technical solution used in the present invention is: a kind of Novel winch, comprise actuating device, input shaft, one-level sun wheel, primary planet is taken turns, primary planet carrier, hydraulic power unit, liquid clutch, secondary solar gear, secondary planet frame, secondary planet wheel and drum brake mechanism, actuating device is connected with input shaft, input shaft is connected with one-level sun wheel, one-level sun wheel is connected with primary planet wheel gear, primary planet wheel sidepiece is provided with primary planet carrier, primary planet carrier is connected with secondary solar gear, secondary solar gear is connected with secondary planet wheel gear, secondary planet wheel sidepiece is provided with secondary planet frame, secondary planet frame is connected with liquid clutch, liquid clutch is connected with hydraulic power unit by pressure duct, described drum brake mechanism is arranged on the input shaft between actuating device and one-level sun wheel, and the outer of described primary planet carrier is connected with winch drum gear with the outer of secondary planet frame.
Further, also comprise plate disc brake, plate disc brake is arranged on the end plate of winch drum.
Compared with prior art, planetary transmission system combines with liquid clutch and drg by the present invention, and not only compact conformation, transmission efficiency are high, reliable operation, have good soft-start feature and the advantage of speed regulation characteristics simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of Novel winch, comprise actuating device 1, input shaft 2, one-level sun wheel 3, primary planet wheel 4, primary planet carrier 5, hydraulic power unit 8, liquid clutch 9, secondary solar gear 11, secondary planet frame 12, secondary planet wheel 13 and drum brake mechanism 14, actuating device 1 is connected with input shaft 2, input shaft 2 is connected with one-level sun wheel 3, one-level sun wheel 3 and primary planet are taken turns 4 gears and are connected, primary planet is taken turns 4 sidepieces and is provided with primary planet carrier 5, primary planet carrier 5 is connected with secondary solar gear 11, secondary solar gear 11 and secondary planet are taken turns 13 gears and are connected, secondary planet is taken turns 13 sidepieces and is provided with secondary planet frame 12, secondary planet frame 12 is connected with liquid clutch 9, liquid clutch 9 is connected with hydraulic power unit 8 by pressure duct 10, described drum brake mechanism 14 is arranged on the input shaft 2 between actuating device 1 and one-level sun wheel 3, and the outer of described primary planet carrier 5 is connected with winch drum 7 gear with the outer of secondary planet frame 12.
Preferably, the present invention also comprises plate disc brake 6, and plate disc brake 6 is arranged on the end plate of winch drum 7, together with drum brake mechanism 14, realizes two staged braking, guarantees that deceleration and stopping performance is safe and reliable.
Working process: actuating device 1 drives one-level sun wheel 3 to rotate by input shaft 2, one-level sun wheel 3 drives primary planet carrier 5 and secondary planet frame 12 to rotate successively, thus drive winch drum 7 to rotate, the pressure size of the hydraulic oil exported by hydraulic power unit 8, the positive pressure between liquid clutch 9 friction lining can be controlled, and then change output torque and the output speed of primary planet carrier 5 and secondary planet frame 12, reach and control winch drum 7 soft start and speed governing.
