It relates to a water pipe combined fire truck worktable capable of rotating 360 degrees having a water pipe coupling structure capable of collectively performing fire extinguishing work.

In general, a fire engine is a vehicle for extinguishing a fire with water or extinguishing fluid by moving to a fire site in the event of a fire. The fire engine includes a pump fire engine equipped with a high-power main pump and a water tank equipped with a water tank. There are chemical fire engines that spray special fire extinguishing fluids on fire, and ladder fire trucks with ladders to rescue the lives of high-rise buildings.

In the event of a fire, the above-mentioned various types of fire trucks are appropriately dispatched to the fire site to extinguish the fire.

However, compared to the increased amount of vehicles, the road does not reach the increased amount, and it is difficult for the fire truck to move to the fire site due to the width of the road, the lack of fire fighting roads, and illegal parking on the road, etc., and fire trucks having different functions The fire was dispatched to the fire site, and economical enormous losses were incurred to complete the fire suppression according to each role.

As a prior art that has been disclosed to solve the above problems, Korean Patent Registration No. 1050257 (2011.07.12.) has an extinguishing liquid tank for storing the extinguishing liquid, and is connected to the extinguishing liquid tank and connected to the extinguishing liquid tank to drive the engine.

However, in the case of the above-mentioned prior art, in the case of the registered patent publication No. 1050257, it is difficult to extinguish a fire in a high-rise building because the angle of fire extinguishing agent injection can be adjusted only at the location of the fire-fighting vehicle, and there is a problem that it is impossible to save the height of life.

In addition, in the case of the registered patent publication No. 1663500 among the above-mentioned prior arts, the conversion angle setting for switching of the working direction is extremely limited because only the elevator for the boarding of firefighters is provided on the barn legs that can be extended only in length. However, there is a technical limitation that the application and function of fire engines are extremely limited because the workability for fire suppression is poor, and it is possible to proceed only with lifesaving in accordance with the aerial work.

In particular, the fire truck work table according to the prior art is simply in the form of a work table on the chassis cap, and the tarpaulin is provided only in the front, and the fire fighting vehicle must be less than 4 m in height in accordance with the fire standard, so it is manufactured under 3.8 m in the case of a small ladder car. Even if the worktable is rotated, there is a problem in that it cannot exceed 30 degrees to the left and right, so that a large restriction may be applied to firefighting work and aerial rescue work.

In addition, if all the fire engines with each function are dispatched, the firefighters, and the water tank and the fire extinguishing tank, which have a composite function capable of saving life and fire, are equipped with firefighters. It is a situation that demands the development of a double cap type small fire truck that can be loaded by as many firefighters as possible.
