crane

Abstract

The invention relates to the technical field of cranes, in particular to a crane. The crane comprises a control cabin and a hook and further comprises a head-up display system. The head-up display system comprises a projection device and a control device, wherein the projection device is mounted in the control cabin and used for projecting to-be-monitored information of the crane onto a windshieldof the control cabin to be displayed, and the control device is used for adjusting the projection direction of the projection device according to the position of the hook. The head-up display systemis arranged in the crane, and the head-up display system can project the to-be-monitored information directly onto the windshield of the control cabin according to the position of the hook so that anoperator can observe the information projected onto the windshield along with moving of a weight, back and forth switching of the view of the operator between a lifted object and the displayed information is reduced, and observation convenience is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane. Background technique [0002] When the crane is performing lifting operations, the operator needs to obtain the parameters of the force limiter and other operating parameters in real time, so as to grasp the safety status of the crane at any time, such as lifting weight, angle, amplitude, torque percentage, etc. In the prior art, these parameters that need to be obtained in real time are usually displayed through a display screen fixed on the instrument panel in front of the control room. The main problem with this display method is: since the position of the instrument panel is usually low, the operator needs to lower his head to see it, which is inconvenient to observe, especially when the hoisted object is hoisted to a high place, the operator needs to look up repeatedly to see the hoisted object , look down at the display, it is easy to cause operator fatigue, and th...

Problems solved by technology

The main problem with this display method is: since the position of the instrument panel is usually low, the operator needs to lower his head to see it, which is inconvenient to observe, especially when the hoisted object is hoisted to a high place, the operator needs to look up repeatedly to see the hoisted object , look down at the display, it is easy to cause operator fatigue, and the operating parameters cannot be monitored during the lifting period, the monitoring parameters will be missed, and there is a safety risk; moreover, because the position of the display screen is fixed, the position of the hoisted object is constantly changing. Changing, the operator's gaze also needs to move continuously with the heavy objects on the hook, therefore, the operator's gaze inevitably has to switch frequently between the suspended object and the display, which is prone to fatigue and inconvenient to observe
