Description

  The present invention relates to a fire hose carriage for carrying out fire fighting activities by transporting a fire hose to an underground fire hydrant or the like installed at a predetermined position when a fire occurs.

  In general, fire extinguishing equipment can be started in a short time in a city with fire extinguishing facilities, but underground hydrants and ground hydrants can be started in depopulated areas such as the countryside. Even if a fire engine is installed, it may take a relatively long time for the fire engine to reach the fire hydrant installation site after receiving notification of the occurrence of a fire, which increases the damage caused by the fire. Even in densely populated areas, initial fire fighting activities by residents etc. are important while the fire is weak to prevent the spread of damage.

  For this reason, for example, as described in Patent Document 1, a transport carriage equipped with a fire extinguishing device such as a fire hose that can perform an initial fire fighting activity before the fire truck arrives has been developed. This truck for transporting fire extinguishers is a vertically long rectangular frame-shaped carriage body having an upper end that is curved in an arm shape, and a pair of left and right pivotally supported on both sides of the bottom lower end of the carriage body. And a pedestal projecting so as to be orthogonal to the trolley body from the lower end of the trolley body to the front, and placed on this pedestal in a state where they are overlapped in the front and back, and the upper part is a hose Two or three fire hoses wound in a spiral shape held by a guard, a stand pipe and a fire hydrant opening / closing key handle arranged in parallel with each other on a frame provided at the bottom lower end of the main body of the carriage It has a structure equipped with a pipe.

  Further, in Patent Document 2, a fire hose carrier (a fire truck carrying truck) equipped with a fire extinguisher as described above is stored in a standing state in a transport cart storage box installed on a street or the like. It is described.

  In the event of a fire, grip the handle and pull the firefighting equipment transport cart diagonally while pulling it out of the storage box and transport it to a nearby fire hydrant installation position. If the fire hydrant is an underground fire hydrant, standpipe Connect the bottom end of the fire hose to the fire hydrant and stand from the fire hydrant to the ground.Connect the base end of the fire hose to the top discharge port of the standpipe with the connection bracket, and connect another fire hose as necessary. After connecting a fire hose and connecting a tube with a spray nozzle to the tip of the connected fire hose, the fire hydrant valve is opened by the fire hydrant opening / closing key handle to perform fire fighting activities.
