Coal mine underground fire hose reel device

Abstract

The invention discloses a coal mine underground fire hose reel device which comprises a hoop and high-pressure straight joints. A rotating pipe shaft is fixedly connected between the two high-pressure straight joints and communicated with the two high-pressure straight joints, the hoop is connected to the rotating pipe shaft through a fixing plate, two symmetrical rotating pipe baffles are arranged on the rotating pipe shaft, the rotating pipe shaft between the rotating pipe baffles is movably sleeved with a fixing sleeve, a circular rotating disc plate is welded to the fixing sleeve, and the outer side of the rotating disc plate is fixedly connected with a rotating disc baffle through a reel barrel. The coal mine underground fire hose reel device is mainly used for winding a fire hose at present, the fire hose can be conveniently and quickly wound by using a reel, the hose can be tightly wound, a certain space is saved, the time for winding the hose is saved, the working efficiency is improved, and a good using effect is achieved.

Description

technical field [0001] The invention relates to a fire-fighting device, in particular to a coal mine underground fire-fighting hose reel device, which belongs to the technical field of coal mine fire-fighting equipment. Background technique [0002] Article 249 of the "Coal Mine Safety Regulations" stipulates that the underground fire-fighting pipeline system should be laid to the mining face, and branch pipes and valves should be set every 100m, but branch pipes and valves should be set every 50m in the belt conveyor roadway. In the past, a section of hose was directly connected to branch pipes and valves in coal mines to take water, and it was usually manually rewound when not in use, which was very troublesome. When rewinding the hose, there will be some residual water in the hose. The accumulated water in the hose for a long time may affect the service life of the hose. Affect downhole quality standardization. And the fire-fighting hose reel on the market is simple in ...

Problems solved by technology

In the past, a section of hose was directly connected to branch pipes and valves in coal mines to take water, and it was usually manually rewound when not in use, which was very troublesome

When rewinding the hose, there will be some residual water in the hose. The accumulated water in the hose for a long time may affect the service life of the hose. Affect downhole quality standardization

Moreover, the fire hose reels currently on the market are simple in structure and poor in quality, and are not suitable for underground coal mines with harsh environments.
