Abstract
The utility model discloses a bottom sealing board structure for a protective air-tight portioning door of a subway interval. The bottom sealing board structure is arranged on the lower end of a portioning door and comprises a screw rod transmission device and a bottom sealing board, wherein a transmission shaft of the screw rod transmission device is arranged on the portioning door; and the bottom sealing board is in transmission connection with the transmission shaft of the screw rod transmission device. According to the bottom sealing board structure for the protective air-tight and portioning door of the subway interval, when the screw rod transmission device rotates, a guide shaft is changed to do the rectilinear motion according to helical pitches in corresponding standards along a rotating angle of a driven rotating shaft, and the corresponding rectilinear motion is realized by maintaining the transmission connection between the guide shaft and the driven rotating shaft as well as the fixed connection between the bottom sealing board and a connecting seat on the guide shaft; and the automatic opening and closing of the bottom sealing board along the vertical direction are realized by changing the rotational motion of the screw rod transmission device into the rectilinear motion of the bottom sealing board.

City track traffic engineering is the important connecting line of urban civil air defense Engineering System, major function be ensure traffic safety, goods and materials shift and transportation, the subway station can be used as again the urgent sheltered location of personnel.Rail line after setting up defences is the large-scale civil air defense constructions and installations that is formed by connecting by the tunnel by many stations.As requested protective airtight partition door should be set in position.
(RFJ02-2009) converting from wartime to peacetime production and vice versa has following requirement to " the railway traffic engineering people's air defence design specifications " implemented in July, 2009 to safeguard function:
Because pre-warning time when entering wartime state may be long, the isolated type protection time that surpasses engineering far away, thereby just there is such a case: lead to aperture in addition, guard plot and seal, but underground interval main track safeguard (being the protective airtight partition door between protective unit) is in opening, train can keep operation on a small scale, and its safe escape, transfer and transportation function travel.When closing protective airtight partition door should decide according to the requirement of traffic in wartime and evacuation, and this is also the difference of track traffic underground construction and common people's preventing engineering.
Therefore, for protective airtight partition door, just before a battle be a very important war skill index conversion time.
And the bottom sealing plate of the partition door of existing tunnel installs after just before a battle equipment is enabled, and also need spend suitable manpower and time in wartime like this, actually implements to exist certain difficulty.
The utility model content
Because the problems referred to above, the utility model provides a kind of Subway Tunnel protective airtight partition door bottom sealing plate structure, is arranged at the lower end of described partition door, comprising:
One spindle gear, the power transmission shaft of this spindle gear are arranged on described partition door;
One bottom sealing plate keeps being in transmission connection with the power transmission shaft of described spindle gear.
Further, described spindle gear comprises:
Be arranged at the rotating disc on described partition door;
