Embodiment Construction

[0017] Now in conjunction with accompanying drawing, the present invention will be further described.

[0018] 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 3-stage planetary gear assemblies 7 in the reduction transmission box. The motor is connected to one end of the transmission shaft through the backstop clutch 2, and the other end of the transmission shaft is connected to the drive shaft through the 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, in which the first-stage planetary gear assembly and the second-stage planetary gear ass...

Abstract

The invention relates to an electric double-speed winch and a work method thereof. The electric double-speed winch comprises a motor, a driving shaft, a hoisting drum, a first-stage planetary gear assembly, a second-stage planetary gear assembly and a third-stage planetary gear assembly, wherein a spline and a three-stage central gear, which move along with the driving shaft, are arranged between the second-stage planetary gear assembly and the third-stage planetary gear assembly, and the spline moves along with the driving shaft, forming three work station states. In the first state, the spline is in driving connection with a second-stage planetary gear carrier and a third-stage planetary gear carrier. In the second state, the spline is only in driving connection with the second-stage planetary gear carrier. In the third state, the spline is in driving connection with the second-stage planetary gear carrier and the three-stage central gear of the third-stage planetary gear carrier, and a spring performing a function of pushing and resetting the spline is arranged on the three-stage central gear in a sleeving manner. The work method is: a work station control mechanism drives the driving shaft to axially move, thereby driving the spline to switch among the work station states, and correspondingly, the winch works at a high speed or a low speed. According to the invention, speed regulation is very reliable and convenient, and the work method is suitable for the electric double-speed winch.

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...
