Description

Pneumatic fire-proof rolling shutter door

Technical Field

The utility model belongs to the technical field of fireproof doors, and particularly relates to a pneumatic fireproof rolling door.

Background

Fire doors are required to be installed on an air inlet and return roadway of an underground coal face of a coal mine, and the fire doors are generally arranged outside a stopping and mining line of the roadway and consist of a wall body and a fire-proof plugboard. The wall body is provided with a groove, and when the fireproof plate is used, the fireproof plate is inserted into the groove one by one to achieve the purpose of sealing a tunnel and blocking a fire area. This facility has the following disadvantages:

1. the fireproof plates are inserted into the grooves of the wall body one by one, generally about twenty minutes is needed for the 3 x 4 laneways to be completely inserted and sealed, and the sealing time is long;

2. when the sealing is carried out, at least two persons are required to operate, and a ladder or climbing equipment is arranged at the same time, so that the operation is inconvenient;

3. the fire-proof plate is daily stored in front of the fire-proof door, and the fire-proof plate needs to occupy the roadway to influence transportation of pedestrians and roadways. Meanwhile, the fireproof plate is often moved or lost, and the daily management is troublesome;

4. when a fire disaster happens and the fireproof door needs to be closed, personnel need to operate in front of the fireproof door, and particularly when the fireproof door on the return air side is closed, the personnel are in a toxic and harmful gas or explosion environment and need to be equipped with professional equipment and professional personnel for operation, so that the danger coefficient is high and unsafe;

5. when a fire disaster happens, the fire door needs to be sealed, the fire door receives an alarm and gives an instruction to a professional rescue team member to go down the well to reach the field operation, the time is long, and the best disaster relief time is delayed.

Therefore, in order to meet the current situation, the design and production of the pneumatic fire-proof rolling door are urgently needed to meet the requirement of practical use.

the lower part of the firewall is provided with a limit switch for controlling the fire-proof rolling door to be closed, the limit switch is used for controlling a pneumatic switch, and the pneumatic switch controls a pneumatic motor to be closed;

the fire-proof rolling door is provided with a power source through a pneumatic device, and the pneumatic device is provided with a power air source through an underground compressed air pipeline.

In a further embodiment, the fire-proof rolling door is in a normally open state, the near control switch, the far control switch and the limit switch are in a normally closed state, and the pneumatic switch is in a normally open state.

In a further embodiment, the proximity switch and the pneumatic switch are mounted on the firewall, and the pneumatic switch is higher than the proximity switch.

In a further embodiment, the compressed air pipeline is arranged on the inner side of the firewall.

In a further embodiment, the remote control switch is arranged in the intake fresh air flow.

In a further embodiment, the fire outlets of the firewall correspond to tunnels.

The utility model has the technical effects and advantages that: the pneumatic fireproof rolling door replaces a fireproof plate, is integrally designed and installed, does not occupy the ground of a roadway, does not influence pedestrian transportation, and is simple and convenient in daily management; the daily maintenance is controlled by a proximity switch, the maintenance is simple and convenient, and a ladder or a climbing facility is not needed; when a fire disaster happens, an ordinary person can turn on the remote control switch to close the fireproof door after receiving an instruction, and the fireproof door can be closed conveniently and quickly in a few minutes. Moreover, when the personnel are in the fresh wind flow, no special equipment is needed, safety, reliability and danger are avoided, and the optimal disaster relief time is not missed; when the fireproof rolling door is closed, the fireproof rolling door is integrally closed, and the tightness is superior to that of a split fireproof plate; the limit switch ensures that the pneumatic motor and the fireproof rolling door are not damaged when the pneumatic motor and the fireproof rolling door are closed in place; the pneumatic fireproof rolling door is simple in structure and high in practicability.
