High-altitude operation engineering machinery and working platform monitoring system thereof

Abstract

The invention discloses a working platform load monitoring system, which is used for high-altitude operation engineering machinery, and comprises a weighing sensor, a controller and an overload limiting device, wherein the weighing sensor collects load signals in real time and sends the load signals to the controller. When the load of a working platform is more than the scheduled load, the controller sends an instruction to the overload limiting device, and the overload limiting device stops the motion of the working platform according to the instruction. The invention also discloses high-altitude operation engineering machinery comprising the working platform load monitoring system. The working platform load monitoring system can automatically complete the monitoring of the working platform load, not only can obtain accurate detection results to avoid the waste of loading energy, but also can stop the motion of the working platform when the actual load is close to a scheduled value toprevent safety accidents.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a working platform monitoring system applied to high-altitude operation construction machinery. The present invention also relates to a high-altitude construction machinery comprising the above-mentioned working platform monitoring system. Background technique [0002] At present, high-altitude construction machinery such as climbing platform fire trucks and aerial work vehicles are more and more widely used in production and life. [0003] Aerial work construction machinery usually has a working platform for carrying people or objects. The working platform can be lifted to a certain height by the boom and carry out related operations such as transportation, maintenance, and emergency rescue. [0004] However, the mechanical strength of the boom of the aerial work engineering machinery is limited, and the load of the working platform should be controlled within an...

Problems solved by technology

In most cases, in order to ensure safety as much as possible, the load tends to be overestimated, which leads to the actual load being less than the rated load of the working platform under various motion curves, so the working platform often cannot move along the ideal curve, so it cannot Give full play to the working performance of high-altitude construction machinery, limit its effective working range, and cause unnecessary waste
