Problems solved by technology

However, the axis of the headlight is parallel and fixed to the axis of the upper body, and the direction of beam irradiation of the headlight is the same as that of the upper body. In the front area, there are prone to lighting blind spots, so that the operator cannot accurately judge the situation in the adjacent area ahead, and cannot obtain sufficient information on the working conditions ahead, leaving serious hidden dangers for the safe operation of the excavator and bringing great harm to night work. inconvenient
[0003] Especially during the slewing operation, it is impossible to observe the working conditions of the area to be turned in advance, causing visual obstacles, causing a decrease in operating efficiency, and easily causing accidents such as collisions

Abstract

The invention discloses an illuminating system and engineering machinery. The illuminating system comprises a power source device, a signal collecting device for collecting turn signals, a trigger device, a primary floodlight and auxiliary floodlights used for enlarging illuminating areas. The primary floodlight and the auxiliary floodlights are connected with the power source device, the trigger device is arranged on a connecting wire between the auxiliary floodlights and the power source device, the trigger device is connected with the signal collecting device and used for controlling the auxiliary floodlights to be turned on and turned off according to the turn signals, therefore, illumination blind zones existing during turn are eliminated, the visual field is enlarged, an operator can observe the working conditions of a zone in advance towards which a machine is turned, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an illumination system and construction machinery. Background technique [0002] At present, excavators, as the most commonly used construction machinery, have a high probability of being used at night. However, the axis of the headlight is parallel and fixed to the axis of the upper body, and the direction of beam irradiation of the headlight is the same as that of the upper body. In the front area, there are prone to lighting blind spots, so that the operator cannot accurately judge the situation in the adjacent area ahead, and cannot obtain sufficient information on the working conditions ahead, leaving serious hidden dangers for the safe operation of the excavator and bringing great harm to night work. inconvenient. [0003] Especially during the slewing operation, it is impossible to observe the working conditions of the area to be turned in advance, causing visual ob...
