Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to a safety evacuation staircase and a fire-fighting elevator group for an underground multi-story station. Background Art

[0002] In underground multi-storey stations, in order to provide underground garage personnel with important escape routes in emergency situations such as fire, safe evacuation stairs and fire elevator groups are usually installed in underground multi-storey stations. Existing safe evacuation stairs and fire elevator groups are usually composed of shaft walls, elevator cars, evacuation passages and evacuation stairs.

[0003] For example, the utility model with application number CN201921661410.5 discloses a fire elevator simulation facility, which specifically includes a shaft, wherein the shaft includes a shaft wall and a safety ladder, and the safety ladder is arranged on the shaft wall; an external platform, which is nested outside the shaft, and the external platform includes a support platform and an outdoor staircase 1, and the outdoor staircase 1 is arranged on the support platform; a lifting system, which is arranged in the shaft, and the lifting system includes a traction machine 16, a control cabinet 17, a car 18, a car guide rail 19, a counterweight 20 and a wire rope 21, the traction machine 16 is electrically connected to the control cabinet 17, the car 18 is arranged on the car guide rail 19, and the car 18 is connected to the counterweight 20 by a wire rope 21. The structural design of the utility model is reasonable, which enables students to intuitively and thoroughly learn and master the structural composition, working principle and operation method of the fire elevator, so as to improve learning efficiency.

[0004] However, as for the current traditional underground multi-story station safety evacuation stairs and fire elevator groups, in the event of a fire, since the underground multi-story station is located deep underground, the structure is relatively closed and has limited connection with the outside world. It is mainly connected to the outside world through entrances and exits, ventilation shafts, etc. As a result, when people are evacuated through the evacuation passage, the smoke generated by the fire will also enter the evacuation passage, resulting in reduced visibility in the evacuation passage and increasing the difficulty of evacuation. Utility Model Content

[0005] In view of this, the present invention provides an underground multi-story station safety evacuation staircase and fire elevator group, which has an inflatable door curtain that can automatically form a barrier at the floor entrance in the event of a fire, blocking smoke from entering the evacuation passage. In the event of a fire, when the smoke sensor senses the smoke generated by the fire, it will start the inflation pump, causing the inflation pump to quickly inflate the inflatable door curtain, causing the inflatable door curtain to quickly expand and fit tightly against the floor entrance to form a temporary barrier, blocking smoke from entering the evacuation passage. At the same time, the inflatable door curtain recorded in this application is made of highly fire-resistant transparent material to avoid obstructing people's vision after forming a barrier.

[0006] The utility model provides an underground multi-story station safety evacuation staircase and fire elevator group, which specifically include: a multi-story station main body; a shaft wall is arranged in the multi-story station main body; an elevator machine room is opened on the upper part of the multi-story station main body; a control cabinet is arranged in the elevator machine room; a traction machine is fastened with bolts in the elevator machine room; the traction machine is electrically connected to the control cabinet; an elevator car is arranged in the shaft wall; the elevator car and the traction machine are connected by a steel wire rope; an evacuation passage is arranged on the right part of the multi-story station main body; multi-story stairs are arranged in the evacuation passage; multiple groups of floor openings are opened on the right part of the multi-story station main body; the multiple groups of floor openings are all aligned with the positions of the multi-story stairs; a swing door is arranged at the lower part of the multi-story station main body; and multiple groups of floor doors are arranged on the shaft wall.

[0007] Optionally, the treads of the multi-story staircase are all hollow plate structures; the treads of the multi-story staircase are all filled with asbestos materials; and an evacuation exit is opened at the upper part of the evacuation passage.

[0008] Optionally, multiple groups of floor openings are provided with inflatable door curtains; the right part of the multi-story station body is bolted to multiple groups of air pumps; the air outlets of the multiple groups of air pumps are respectively connected to the multiple groups of inflatable door curtains; the right part of the multi-story station body is bolted to multiple groups of smoke sensors; the multiple groups of smoke sensors are electrically connected to the multiple groups of air pumps.

[0009] Optionally, the exterior of the multi-story staircase is fixedly connected with a plurality of sets of stair handrails; the exteriors of the plurality of sets of stair handrails are hingedly connected with support plates.

[0010] Optionally, multiple groups of lighting lamps are fixedly connected to the upper parts of the multiple groups of stair handrails; the multiple groups of lighting lamps are respectively aligned with the positions of the multiple groups of support plates.

[0011] Optionally, the top surface of the elevator car is centrally connected to a rescue door; two control torsion springs are symmetrically fixedly connected to the outside of the rescue door shaft; the ends of the two control torsion springs are fixedly connected to the elevator car; the right part of the rescue door is fixedly connected to a locking hook; the right part of the elevator car is slidably connected to a locking hanger; the inner side of the locking hanger is fixedly connected to a return spring; the end of the return spring is fixedly connected to the elevator car; the lower inner part of the locking hanger is fixedly connected to a control handle; the control handle is slidably connected to the elevator car; the right end face of the inner wall of the elevator car is fixedly connected to an anti-accidental touch box; the control handle is arranged in the anti-accidental touch box.

[0012] Beneficial effects

[0013] When the smoke sensor senses the smoke generated by the fire, the utility model starts the inflation pump, causing the inflation pump to quickly inflate the inflatable door curtain, causing the inflatable door curtain to expand rapidly and fit tightly against the floor opening to form a temporary barrier, thereby preventing smoke from entering the evacuation passage. At the same time, the inflatable door curtain recorded in the present application is made of a highly fire-resistant transparent material, which avoids obstructing the vision of personnel after forming a barrier, helps to keep the air in the evacuation passage relatively fresh, provides a relatively safe escape passage for evacuees, improves the clarity of vision of evacuees, enables them to find the escape route more quickly, and effectively improves the practicality of the safe evacuation stairs and fire elevator groups in underground multi-story stations.

[0014] When the elevator car is damaged and cannot be opened normally, firefighters can smash the anti-accidental touch box, and then push the locking hanger upwards to disengage the locking hanger from the locking hook. At this time, the rescue door will stand up with the elastic potential energy of the control torsion spring itself, allowing the rescue door to open, making it convenient for firefighters to leave the elevator car through the gap exposed after the rescue door is opened. The operation is simple and quick, and effectively improves the convenience of safe evacuation stairs and fire elevator groups in underground multi-story stations. BRIEF DESCRIPTION OF THE DRAWINGS
