Description

Boom and Ladder Fire Truck Monitor

The present invention relates to a monitor device for a boom and ladder fire truck, and more specifically, for the boom and ladder fire truck used for fire suppression and lifesaving purposes, the automatic leveling of the outrigger to adjust the level of the fire truck to rescue the rescuer Sensing data on the angle, length, wind speed and load in the process of operating the boom and ladder, and by the detected data the safety of the vehicle body by the weight of the boom and ladder itself and the operator and the wind speed and impact. The present invention relates to a monitor device for a boom and ladder fire truck that displays a state by an output device such as a monitor so that a user can easily identify the same.

As is known, in the current situation where the height of the building is getting higher and higher, the boom and ladder fire trucks used for lifesaving and extinguishing activities in the event of a fire in the building have a boom and ladder folded so that the vehicle can be lowered and lowered. The purpose is to save lives and firefighting activities.

In the case of the boom and ladder firefighting vehicle, the folded boom and the ladder are elongated in order to extinguish a fire in a high place or to work in a high position, and the worker provided at the upper part of the elevator performs a necessary work such as fire extinguishing. Therefore, the center of gravity of the sum of the weight of the boom and the ladder itself and the weight of the worker and the equipment, such as the overturning of the vehicle body due to the rotational moment as the deviation from the center of gravity of the vehicle body is normally avoided to prevent this. Outriggers are provided on the body and the safety of the fire truck is ensured by supporting the body in four horizontal positions with respect to the ground by a jack operated hydraulically from the outrigger.

However, such a boom and ladder fire truck, the operator unfolds the outrigger in a horizontal state after arriving at the fire site, and the working conditions such as being hit by wind speed and buildings or obstacles in extending the boom and ladder. Observation with the naked eye causes elongation, which makes it difficult to operate the boom and the ladder.

When the rescuer is rescued in the process of carrying out necessary work such as fire extinguishing on the elevator provided at the top of the boom and the ladder, the center of gravity for the sum of the weight of the ladder itself and the weight of the worker and the equipment, etc. Since the operation is determined by the naked eye, when a certain range is out of the center of gravity of the vehicle body, there is a problem of causing a human accident due to overturning of the vehicle body.

Accordingly, the present invention has been made in view of the above problems, the object of which is to increase the horizontal and boom and ladder of the fire truck by the auto-leveling means of the outrigger operated to extend the boom and the ladder in the event of a high-rise building fire. By the angle, length, wind speed, and load, the weight of the boom and ladder itself and the safety status of the vehicle body are displayed by an output device such as a monitor by the worker, wind speed, and impact, so that the safety status of the boom and ladder can be easily recognized. The present invention provides a monitor device for a boom and ladder fire truck.

In addition, another object of the present invention is to display the operating state of the boom and ladder on the coordinates shown on the monitor and at the same time to display the safety status of the boom and ladder by text and the like.
