Abstract
The utility model discloses a non-contact truck bed lifting alarm device of a dump truck. The non-contact truck bed lifting alarm device comprises a proximity switch, a relay-contactor, a power supply, a sound device and a lighting device, wherein the proximity switch is arranged on a proximity switch support. The proximity switch is arranged between a positive pole and a negative pole of the power supply. The proximity switch is connected with the relay-contactor. The relay-contactor is connected with the sound device and the lighting device which are connected in parallel. When a truck bed is in a normal position, the normally-closed positive-negative-positive (PNP) proximity switch sends out a power-off electric signal, the normally-opened relay-contactor does not motion, and the sound device and the lighting device do not work. When the truck bed leaves the normal position (in a lifting state), the proximity switch sends out a power-on electric signal to drive the relay-contactor to work, a normally-opened contact is switched on to drive the sound device and the lighting device to work, and then the alarm function of the non-contact truck bed lifting alarm device is achieved.
