Abstract

A power winch overcurrent (overload) safety device includes a display panel with an overcurrent (overload) warning display zone. Simultaneously, amperages used in the power winch is set with an upper limit current setting value, and a current actual value is set for an actual amperage. The current setting value and the current actual value are displayed on the display panel. A first plug socket is plugged by a plug head of a controller to perform operating of the power winch, and a second plug socket is further disposed on the electrical control set of the power winch and connected to a circuit set for the current setting value in the electrical control set, and which using for the plug of a current regulator to regulate the current setting value.

Claims

1. A power winch overcurrent (overload) safety device, a side of the power winch disposed with a power source, power generated by the power source transmitted by an internal shaft core to drive a deceleration device, the deceleration device driving a cable pulley to rotate after experiencing deceleration effect so that a steel cable wound on the cable pulley performs motions of positive rotation discharging or counter rotation retracting:

the power winch disposed with an electrical control set electrically connected to the power source to control on or off of the power source;

a front surface of the power winch disposed with a display panel electrically connected to the electrical control set to display operation state and related messages of the power winch;

characterized in that;

items of the display panel comprises an overcurrent (overload) warning display zone setting an upper limit current setting value, which is in connection with use amperage of the power winch, displayed on the display panel and setting a current actual value, which is in connection with an actual amperage of the power winch, displayed on the display panel.

2. The power winch overcurrent (overload) safety device according to claim 1, wherein an external surface of the electrical control set of the power winch is disposed with a first plug socket plugged by a plug head of a controller to perform operating of the power winch.

3. The power winch overcurrent (overload) safety device according to claim 1, wherein an external surface of the electrical control set of the power winch is disposed with a second plug socket plugged by a plug head of a current regulator to regulate the current setting value.

4. The power winch overcurrent (overload) safety device according to claim 1, wherein items displayed by the display panel further comprise:

a power activation display zone displaying that the power winch is at useable state through a light emitting signal;

a vehicle power quantity display zone wherein a power quantity state of the vehicle mounted with the power winch is displayed through a light emitting signal, and wherein when power quantity is as low as a power quantity setting value, a beep sound is generated at the same time to reinforce warning;

a temperature warning display zone, wherein when a temperature of the power source reaches a temperature setting value, a light emitting signal is displayed and a beep sound is activated to warn that operation of the power source must be stopped;

a steel cable direction display zone displaying a traveling direction of the steel cable with a light emitting signal; and

a wireless operating display zone displaying a light emitting signal indicating that the power winch has been transformed into wireless remote control mode.
