Description
Technical Field
The invention relates to the field of installation tools of fire fighting equipment, in particular to an installation tool of a fire fighting spray header.
Background
The fire sprinkler head is applied to the fire sprinkler system, and when the conflagration breaing out, the heat-sensitive component in the fire sprinkler head is because experience the temperature and rise, breaks rapidly, and then makes the water in the pipeline spill through shower head splash box and put out a fire, according to the difference of water spray mode, mainly divide into down the type watering shower nozzle of spouting, goes up the type watering shower nozzle of spouting, side spout type watering shower nozzle at present.
According to the fire-fighting standard, the fire-fighting spray header is widely applied to places such as superstores, hotels and office buildings and is uniformly distributed on the ceilings of the places according to a certain distance. As shown in fig. 8, the fire sprinkler head 5 is in communication with the fire feed pipe 6 by a screw-fit.
Because the floor height of the place is higher, the fire-fighting spray head is further far away from the ground, and particularly for a downward-spraying type water spray head, because the opening of the downward-spraying type water spray head is arranged upwards, workers can mount the fire-fighting spray head only by climbing a scaffold or a ladder and other tools; meanwhile, due to the fact that the number of the fire-fighting spray headers is large, workers need to frequently climb up or down a ladder during installation, and therefore installation difficulty of the fire-fighting spray headers is increased.
