Embodiment Construction
[0015] Now in conjunction with accompanying drawing, the present invention will be further described.
[0016] Such as Figure 1-4 As shown, the electric two-speed winch includes a winch support, a motor 1, a transmission shaft 16, a winch 4, a reduction transmission box 15, and a station control mechanism. There are 14 first-stage planetary gear sets, 12 second-stage planetary gear assemblies, and 7 third-stage planetary gear assemblies in the reduction transmission box. The motor is connected to one end of the drive shaft through a backstop clutch, and the other end of the drive shaft is connected to a drive shaft through a primary center wheel. The first-stage planetary gear assembly, the first-stage planetary gear assembly, the second-stage planetary gear assembly, and the third-stage planetary gear assembly are sequentially connected to form a reduction transmission, and the first-stage planetary gear assembly and the second-stage planetary gear assembly form a second-sta...

The invention relates to an electric double-speed winch and a working method thereof. The electric double-speed winch comprises a motor, a transmission shaft, a hoisting drum, a first-level planet wheel assembly, a second-level planet wheel assembly and a third-level planet wheel assembly. A spline moving along with the transmission shaft is arranged between the second-level planet wheel assembly and the first-level planet wheel assembly, and the spline moves along with the transmission shaft in two station states. According to the first station state, the spline is in transmission connection with a second-level planet wheel support of the second-level planet wheel assembly and a third-level planet wheel support of the third-level planet wheel assembly, and according to the second station state, the spline is in transmission connection with the second-level planet wheel support of the second-level planet wheel assembly and a third-level central wheel of the third-level planet wheel assembly, and the third-level central wheel is sleeved with a spring playing pushing and buffering roles on the spline. According to the working method of the electric double-speed winch, the transmission shaft is driven by a station control mechanism to move in the axial direction, and therefore the spline is driven to be switched between the two station states, and high-speed work and low-speed work of the winch are correspondingly achieved. According to the electric double-speed winch and the working method thereof, speed regulation is reliable and convenient.
Description
technical field [0001] The invention relates to a winch, which is an electric double-speed winch and its working method. Background technique [0002] An electric winch is a device that can be used for traction, such as a car winch, and can be used for self-rescue and rescue in harsh environments. The existing electric winch is mainly composed of a motor, a transmission shaft, a reduction transmission box, a winch and other structures, relying on the reduction transmission box to connect the power between the motor and the winch, so that the steel wire rope wound on the winch can generate a relatively high speed. Large traction force realizes the winch traction function. In addition to the traction function, the electric winch is often equipped with a clutch mechanism in the reduction transmission box to cut off the power connection between the motor and the winch, so as to facilitate the pulling operation of the wire rope on the winch. Therefore, most of the existing elec...
