Description

Vehicle-mounted emergency searchlight

Technical Field

The utility model belongs to the technical field of the illumination lamps and lanterns, concretely relates to on-vehicle emergent searchlight.

Background

A searchlight is a device which has a strong light source and a concave mirror capable of intensively projecting light rays to a specific direction and is used for remote illumination and search. Greater light intensity can be achieved by concentrating the exiting beam in a small solid angle (typically less than 2 degrees) with a mirror or lens. Considering the volume, weight and convenient operation of the device, most searchlights are attached with foot stands or movable carriers, and large searchlights even special trucks are used as carriers.

The traditional searchlight mostly adopts a direct current or stepping motor to match with a synchronous wheel and a synchronous belt to realize the rotation of X and Y axes. Synchronous belt drive has the advantages of belt drive, chain drive and gear drive. In the synchronous belt transmission, the belt and the belt wheel are engaged to transmit motion and power, so that the belt and the belt wheel do not slide relatively and accurate transmission ratio can be ensured. The transmission noise is less than that of belt transmission, chain transmission and gear transmission, the wear resistance is good, oil lubrication is not needed, and the service life is longer than that of a friction belt. The main disadvantages are high requirements for manufacturing and mounting precision and strict requirements for center distance. Therefore, the synchronous belt is widely applied to medium and low power transmission requiring accurate transmission ratio. In outdoor environment application, most of the transmission equipment can normally exert the characteristics of the transmission equipment by a fixed or stable platform. When the disaster place or the area needing to be applied is in the open air, mountain forest, grassland, sea lake and other harsh captive environments, the operation of general equipment is not stable, and some conditions need to be operated flexibly, so that the bumpy vibration can be generated, and the use requirement of synchronous belt transmission can not be met.
