Crane intelligent arm head lamp device and control method

Abstract

The invention discloses a crane intelligent arm head lamp device and a control method. The crane intelligent arm head lamp device comprises a lamp head, a connection support, an execution motor, a supporting seat, an inclination angle detection apparatus, a main controller and a selection controller; the inclination angle detection apparatus, the execution motor and the selection controller enable respectively electric connection with the main controller; and the control method comprises the following steps: under an automatic mode, the inclination angle detection apparatus detects the attitude of the lamp head, the main controller treats the attitude signal, the execution motor performs closed-loop control, the irradiation direction of the lamp head is vertical and downward; under a hand-operated mode, the main controller detects the signal of the selection controller, the execution motor performs closed-loop control, so that the irradiation direction of the lamp head satisfies the real requirement. The crane intelligent arm head lamp device empolys active control, the structure is simple, the defense of outside force influence is realized, so that safe and stable illumination can be realized; the electrical installation enables enclosed space, safe usage and life can be ensured, two modes can be freely switched, the hoisting position can be timely tracked, lamp head irradiation direction can be controlled at will, and the on-site complex light illumination demand at condition can be satisfied.

Description

technical field [0001] The invention relates to a lighting device and a control method, in particular to a crane arm head device and a control method. Background technique [0002] The headlight of the crane arm is a lighting device to ensure the normal and safe operation of the crane at night. The headlights of the traditional crane arm are fixedly installed on the boom, and the light can only be irradiated along a fixed direction, and cannot track the position of the hoisting weight in time with the amplitude and expansion of the boom. When working at night or in an environment with insufficient light, it is difficult for the operator to judge the actual situation of the lifting place and the specific position of the hoisting weight in the air, which increases the danger and difficulty of the work and reduces the work efficiency. [0003] Aiming at the above problems, the patent ZL201120439286.5 designed a purely mechanical arm headlight mechanism, which uses a counterwei...

AI Technical Summary

Problems solved by technology

First of all, if the damping of the damping device is too large, it is easy to cause the movement of the counterweight to be stuck; if the damping of the damping device is too small, the counterweight is easy to shake, which will cause the shaking of the arm headlight

Secondly, this design is difficult to resist the influence of high-altitude wind and vehicle body vibration, and it is difficult to achieve better expected design results under various working conditions

In addition, the light is always vertically downward, and the direction of the lamp head cannot be arbitrarily controlled to track the position of the hoist from time to time. It is difficult to meet the complex lighting requirements of the working site, and the risk factor of night construction is high.
