Description

Technical Field

[0001] The utility model relates to the technical field of railway construction safety, in particular to an explosion-proof and fireproof door based on a railway tunnel. Background Art

[0002] Railway tunnel is a relatively closed space. Usually, there are cross-channel protective doors in the tunnel. When fire and explosion occur, personnel can enter the safe area through the protective doors to ensure their safety. In order to gain enough evacuation time, the protective doors must have good fire resistance and the ability to resist explosion shock waves.

[0003] Due to the operation of trains in railway tunnels, large lateral wind pressure is often generated in the tunnel. Conventional fire doors are only locked by one lock. The lateral wind will produce continuous wind pressure on the explosion-proof and fire doors on both sides of the tunnel. The explosion-proof and fire doors will hit the door frames under the action of wind pressure. Under the action of long-term lateral wind pressure, a single lock may be damaged by impact or fall off to the track side. At the same time, conventional explosion-proof and fire doors are relatively simple in function and only have a blocking effect, so there may be problems with safety.

[0004] Based on this, it is necessary to develop a multifunctional explosion-proof fire door. Utility Model Content

[0027] When a dangerous situation occurs, the staff quickly passes through the passage, pushes the two fire doors 2 to close, and operates the manual locking mechanism 3 to lock the two fire doors. After that, the smoke outlet 4 extracts the smoke that escapes through the passage. At the same time, the spray mechanism sprays water mist to spray the location or surrounding of the door frame 1 to suppress the spread of fire, and at the same time, it also suppresses the spread of thick smoke to a certain extent. The whole structural design is simple and reasonable, and can play a good role in fire prevention, explosion prevention, smoking and fire extinguishing.

[0028] As a preferred embodiment, a vertically extending smoking port 4 is provided on a vertical beam on one side of the door frame 1, a first dust cover 42 is detachably installed at the smoking port 4, a smoking box 41 is embedded in the smoking port 4, and the smoking box 41 is connected to the smoking pipe 6 through a pipeline.

[0029] In the above embodiment, when not in use, the smoking port 4 is shielded by the first dust cover 42. When a dangerous situation occurs, the first dust cover 42 is quickly removed, and thick smoke will enter the smoking and 41 and then be sucked away by the smoking pipe 6. This structure can not only shield and protect the smoking port 4 when not in use, but also realize quick smoking operation when in use.

[0030] In this embodiment, a smoke exhaust fan or pump is provided on the pipeline. Of course, a fan or pump can also be connected to the outlet end of the smoke exhaust pipe 6 or the pipeline.

[0031] In this embodiment, a filter screen is also provided in the smoking port 4 .

[0032] As a preferred embodiment, the above-mentioned spray mechanism includes a diverter 8 embedded in the top crossbeam of the above-mentioned door frame 1, and the lower end of the above-mentioned diverter 8 is connected to a plurality of horizontally spaced nozzles 81, and the above-mentioned diverter 8 is connected to the above-mentioned water pipe 7 through a pipeline, and the above-mentioned water pipe 7 is provided with a valve.

[0033] In the above embodiment, when in use, by opening the valve, the municipal water network into which the water pipe 7 is integrated can provide pressurized tap water, which is sprayed out through the nozzle 81. The spraying direction can be toward the inner area of ​​the door frame 1 or the outer area, which is set according to actual needs.

[0034] As a preferred embodiment, the valve is an electrically controlled valve and is connected to a button controller, which is disposed near the door frame 1 .

[0035] In the above implementation scheme, when encountering a dangerous situation, it is only necessary to operate the button controller, which is very simple and quick.

[0036] As a preferred embodiment, the manual locking mechanism 3 includes a fixing rod 31, a plurality of locking pins 32 and a driving member 33, wherein a cavity is provided inside a side of the fire door 2 away from the door frame 1, the fixing rod 31 is vertically arranged in the cavity, the plurality of locking pins 32 are vertically fixed to the fixing rod 31 and pass through the through holes adapted to the side ends of the fire door 2, the plurality of locking pins 32 are spaced apart up and down, and a locking socket corresponding to the locking pins 32 is provided on the side end of another fire door 2 away from the door frame 1, the driving member 33 is connected to the fixing rod 31, and a guide groove 21 passing through the cavity is horizontally provided on one side of the fire door 2, and the driving member 33 extends into the guide groove 21.

[0037] In the above embodiment, after closing the two fire doors 2, the driving member 33 is operated to translate along the guide groove 21, thereby driving the fixing rod 31 and the locking pin 32 to translate, so that the locking pin 32 is inserted into the locking socket at the side end of the other fire door 2. The operation is very simple.

[0038] As a preferred embodiment, the driving member 33 includes a sleeve 331 and a driving rod 332. The sleeve 331 is arranged perpendicular to the fire door 2, one end of which is connected and fixed to the middle part of the fixing rod 31, and the other end extends into the guide groove 21. The driving rod 332 is detachably plugged into the other end of the sleeve 331.

[0039] In the above implementation scheme, the driving rod 332 and the sleeve 331 are designed to be detachable. When not in use, the driving rod 332 is removed and the sleeve 331 is hidden in the guide groove 21. When in use, the driving rod 332 is inserted into the sleeve 331 to drive the fixed rod 31 to translate, which is very clever and reasonable.

[0040] In this embodiment, a safety box for accommodating the driving rod 332 is embedded on the door frame 1. When it is needed, the fresh-keeping box is opened and the driving rod 332 is taken out. When it is not needed, the safety box is sealed.

[0041] In this embodiment, a second dust cover 22 is detachably provided at the guide groove 21. When not in use, the second dust cover 22 covers the guide groove 21 to prevent dust from entering, and at the same time, it is more beautiful. When it is needed, the second dust cover 22 can be removed, which is very convenient. A protrusion is provided on the inner side of the second dust cover 22, and the protrusion is inserted into the sleeve 331 to maintain the position of the sleeve 331, ensuring that the sleeve 331, the fixing rod 31 and the locking pin 32 will not shift when not in use.
