Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Please refer to FIG. 1 , the electric winch of the present invention includes a drum unit 1 , an automatic braking unit 2 , a gearbox unit, a cable fairlead 4 and a motor 5 .

[0021] The drum unit 1 is driven by a motor 5, and it includes a drum 10 for winding cables, a front cover 11 positioned at both ends of the drum 10, a rear cover 12, and a connecting rod 13 connected between the front and rear covers 11, 12 . The drum 10 can change the direction of rotation under the control of the remote controller.

[0022] The gearbox unit includes three stages of planetary gears: a first stage planetary gear 31 , a second stage planetary gear 32 and a third stage planetary gear 33 . The three-stage planetary gears are connected successively, and as a transmission mechanism, the energy generated by the motor 5 is converted into a powerful traction force so that th...

Abstract

The present invention provides an electric winch and comprises a drum wheel unit (1), an automatic brake unit (2), a gearbox unit, a cable-guard (4) and a motor (5). The automatic brake unit is inserted in the drum wheel unit, the gearbox unit is connected with the automatic brake unit, and the cable-guard is arranged on the drum wheel unit. With friction contact between a spring of the automatic brake unit and the drum wheel, the present invention can prevent inversion when retaking the cable and can brake automatically in time even if inversion is occurred.

Description

technical field [0001] The invention relates to the technical field of winches, in particular to an electric winch. Background technique [0002] Electric winches are mainly used for off-road vehicles, agricultural vehicles, ATV sports vehicles, yachts, and other special vehicles. It is a self-protection and traction device for vehicles and ships. It can perform self-rescue of vehicles in harsh environments such as snow, swamps, deserts, beaches, and muddy mountain roads, and may perform operations such as clearing obstacles, dragging objects, and installing facilities under other conditions. , It is an indispensable safety device for petroleum, hydrology, environmental protection, forestry, transportation, public security, frontier defense, and other field sports. [0003] The working principle inside the electric winch is: the electric power of the car battery first drives the electric motor. The motor rotates to drive the drive shaft, which in turn drives the planetary ...
