Abstract
The invention relates to a double-speed electric capstan and a use method thereof. According to the design, the double-speed electric capstan is characterized in that a two-stage planet wheel assembly in a gearbox is provided with two sets of planet wheels with different transmission ratios, and the two sets of planet wheels are correspondingly provided with independent outer gear rings. The gearbox is provided with a shifting handle rotating in a limited mode, and the end, extending into the gearbox, of the shifting handle is provided with a locking head which rotates within a limited stroke along with the shifting handle and switches the locking states with the two outer gear rings. When the shifting handle rotates to the middle position of two limiting ends and the locking head rotates along with the two outer gear rings, the locking head makes no contact with the two outer gear rings. The use method comprises the steps that the shifting handle is rotated, and the locking states between the two outer gear rings and the locking head are switched, so that the rotation speed I and the rotation speed II of the capstan are realized; and when the shifting handle is rotated to the middle position of the two limiting ends, the two outer gear rings are in an idle state, and the disengagement state of the capstan is realized. The double-speed electric capstan is simple in structure and small in size, and the speed adjustment operation is convenient and reliable.
Description
Technical field
The present invention relates to capstan winch, it is a kind of double-speed electric winch and using method thereof.
Background technology
Power capstan is a kind of device that can be used for traction, such as automobile winch, is used in severe environment and saves oneself and sue and labour. Existing power capstan is primarily of structure compositions such as motor, transmission shaft, satellite gear reduction box, winding drums, rely on the power that satellite gear reduction box is connected between motor and winding drum, make the wireline being wrapped on winding drum can produce bigger tractive force, it is achieved capstan winch traction function. Power capstan, except traction function, is often provided with engaging and disengaging gear in satellite gear reduction box, is connected for the power cut off between motor with winding drum, thus facilitate wireline on winding drum pull operation. Therefore existing power capstan is mostly the capstan winch of single speed band clutch for clutch control, but this kind of single speed capstan winch scope of application is comparatively limited, the more difficult operation being applicable to many speed traction working conditions. For this reason, prior art again discloses some power capstans with speed-regulating function, but existing speed governing is mostly realized by the speed governing gear of different chi ratio, complex structure is not only installed, volume is relatively big, and operation is comparatively required great effort, therefore needs to be improved by existing speed governing capstan winch.
Summary of the invention
For overcoming above-mentioned deficiency, it is an object of the invention to provide a kind of double-speed electric winch and using method thereof to this area so that it is solving existing like product two velocity modulation joint structure installment comparatively complicated, speed governing operates the technical problem of comparatively inconvenience. Its objective is to be achieved through the following technical solutions.
This double-speed electric winch comprises motor, winding drum, transmission shaft, gear mechanism, hexagonal middle wheel, gear mechanism comprises wheel casing, and it is positioned at the primary planet wheel assembly of wheel casing, secondary planet wheel assembly, third-level planetary wheel assembly, motor output end connection for transmission axle one end, the transmission shaft the other end connects hexagonal middle wheel, hexagonal middle wheel is in transmission connection primary planet wheel assembly, primary planet wheel assembly, secondary planet wheel assembly, third-level planetary wheel assembly are in transmission connection successively to be formed and slow down, and third-level planetary wheel assembly is in transmission connection winding drum. Its structure main points are that described secondary planet wheel assembly is provided with the different satellite gear of two groups of transmitting ratios, and these two groups of satellite gear correspondences are provided with independent external toothing, two external toothings all rotate and are positioned in described wheel casing, and the side face of two external toothings is equipped with lock part position, between the lock part position of two external toothings, form ring groove; Described wheel casing is provided with group hand in rotary limited, and one end that group hand stretches in wheel casing is provided with tapered end; When described group of hand turns to one of them positive stop end, described tapered end only coordinates lock only with the lock part position of an external toothing in described secondary planet wheel assembly; When described group of hand turns to another positive stop end, described tapered end only coordinates lock only with the lock part position of another external toothing in described secondary planet wheel assembly; When described group of hand turns to the mid-way of two positive stop ends, in the ring groove of described tapered end between two external toothings, and when rotating with two external toothings, tapered end does not contact with two external toothings.
