Description

SPECIAL VEHICLE CAPABLE OF DISPLAYING OUTRIGGER INSTALLATION POSITION}

The present invention relates to a special vehicle capable of displaying an outrigger installation position.

In general, when a special vehicle such as a fire engine arrives at a work site, an outrigger is deployed and lands on the ground so that the vehicle body of the special vehicle does not shake, so that the leveling of the vehicle body is adjusted.

In particular, in the case of fire engines equipped with elevated ladders used to extinguish fires in high-rise buildings, the risk of overturning occurs when the vehicle body cannot maintain a stable level with the ground because it is operated in the extended state. Therefore, the installation work of the outrigger is the most important thing.

In the case of fixing the vehicle body in a stable state using an outrigger, the vehicle body is maintained in a stable state by properly extending the horizontal bar of the outrigger and then lowering the vertical bar of the outrigger to make it completely contact with the ground.

However, in spite of a very urgent situation such as a fire, the conventional outrigger installation is not only very slow because the operator must operate the horizontal bar and the vertical bar of the outrigger after checking the working position one by one. Since the operation of the horizontal bar and the vertical bar of the outrigger must be installed according to the experience of an experienced operator, the unskilled person of a special vehicle not only takes more time to install the outrigger, but also causes a large accident due to the incomplete installation of the outrigger. There were many problems such as.

In the present invention, the driver or assistant of a special vehicle can quickly determine whether an outrigger can be installed in a narrow place or a disaster site, and through this, an outrigger can be quickly installed, thereby minimizing personal injury at a disaster site. It aims to provide special vehicles.

It will be understandable.

A special vehicle according to an embodiment of the present invention includes a vehicle body; At least a pair of outriggers that are deployed to both sides of the vehicle body and include a horizontal bar and a vertical bar; A driving unit driving the outrigger; A sensor unit sensing an abnormal object in the deployment space of the outrigger; A display unit for projecting an identification mark on the ground at an installation position of the outrigger; And a controller configured to control operations of the display unit and the driving unit based on the abnormal object sensing data sensed by the sensor unit. It may include.

The sensor unit comprises: a first sensor unit configured to sense an abnormal object in the horizontal direction of the horizontal bar; And a second sensor unit for obtaining image data by photographing a space in which the outrigger is deployed. It may include.

The first sensor unit may be a distance measurement sensor.

When the distance value in the horizontal direction of the outrigger measured by the first sensor unit is less than a preset first distance value, the control unit determines that an abnormal object is disposed in the deployment space of the outrigger, and the display unit and the The operation of the driving unit can be suppressed.

A plurality of first sensor units may be disposed to be spaced apart in a vertical direction on a vehicle body adjacent to the outrigger or on a vertical bar of the outrigger.

The first sensor unit may be disposed on a vehicle body adjacent to the outrigger or on a vertical bar of the outrigger, and may be movable in a vertical direction.

The display unit may include a first display unit for projecting a dot-shaped identification mark on the ground at an installation position of the outrigger or a second display unit for projecting a line-shaped identification mark on the ground at an installation position of the outrigger.

According to an embodiment of the present invention, a driver or an assistant of a special vehicle can quickly determine whether an outrigger can be installed in a narrow place or a disaster site, and through this, an outrigger can be quickly installed, resulting in personal injury at a disaster site. Can be minimized.
