It should be noted that the left door frame, the right door frame, the upper door frame and the lower door frame may be separate structures or may be an integrated structure, and the present invention is not particularly limited.
As shown in fig. 1, the micro automatic fireproof door frame of the embodiment of the invention is formed by assembling and combining a left door frame 1, an upper door frame 4, a right door frame 12, a lower door frame 23, a left upper connecting plate 2 and a right upper connecting plate 11 through bolts, the outline shape of the convex door frame takes the arch structure characteristics of a cable tunnel into consideration, and under the condition that the passing space of the door is not reduced, the height of the left door frame 1 and the height of the right door frame 12 are reduced to adapt to the arc trend of the arch crown of the tunnel, so that enough space allowance is reserved for field installation. The door frame is made of galvanized steel sheets. The working indicator lamps 24 are mounted on two sides of the left door frame 1, and are in a green flashing state after completely opening or closing the door, orange flashing during opening/closing the door, and red flashing during failure, so that the working state of the whole miniature automatic fireproof door can be displayed.
As shown in fig. 2, taking the right door frame 12 as an example, the right door frame has a function of accommodating a driving component in addition to a function of supporting a frame as a whole door frame, the right door frame box 1201 is formed by bending a galvanized steel plate, a motor 15 is fixed inside the right door frame box 1201 through a motor mounting plate 16, a gear 17 is installed on a shaft of the motor 15 and is fixed through 18 jackscrews, a motor driver 14 and a controller 13 are installed inside the right door frame box 1201, a position sensor 19 is installed on a sensor mounting plate 20, the sensor mounting plate 20 is fixed inside the right door frame box 1201 through a bolt, a right door frame cover 1203 and the right door frame box 1201 are connected through a bolt 1204 and a gasket 1205, when the debugging motor and a driving control device thereof need to be installed, only the right door frame cover 1203 needs to be opened, and a groove is formed in the side surface of the right door frame box 1201: the door opening sensing plate 701 and the door closing sensing plate 702 will cross the slot space when the door is opened and closed, and enter the sensing area of the corresponding position sensor, and two sensors 19 are arranged in the left door frame box and the right door frame box. When the automatic fireproof door is closed, a reserved gap between the door leaf and the door frame meets the requirement of the fireproof door, the door leaf can also isolate the spaces on two sides of the door, and smoke and the like are prevented from channeling to the other side from the slotting part of the right door frame box 1201. In the same way, the left door frame 1 and the right door frame 12 have the same function and symmetrical structure, the motors 15 and the drivers 14 are also installed in the left door frame 1 and the right door frame 12, and the two motors 15 share one controller 13 (installed in the right door frame 12).
As shown in fig. 3 and 4, taking the right door 7 as an example, the right door 7 is made of galvanized steel plate, and is filled with fireproof rock wool, and a space allowing the rail to pass is opened, and a fireproof sealing strip is arranged between the rail and the door. The right door leaf 7 is connected with the connecting shaft 8 through a screw 703, the connecting shaft 8 and a door assembly area are of a two-side milling structure and can be tightly attached to the door leaf, the driven gear 22 is assembled with the connecting shaft 8 through a spline, the lower end face of the gear is attached to a shaft shoulder of the connecting shaft 8, and the upper end face of the gear is prevented from axially moving through the shaft stopper 21. The driven gear 22 is engaged with the gear 17. The upper end and the lower end of the connecting shaft 8 are respectively arranged on bearings 10, and the bearings 10 are arranged in the bearing block 3 and are sealed and fixed through bearing covers 9. The bearing seat 3 is installed on the upper door frame 4 and the lower door frame 23 through bolts, so that the whole door leaf is fixed, namely, the left door leaf and the right door leaf are fixed on the upper door frame and the lower door frame through the connecting shaft 8, the left door leaf and the right door leaf are fixed on the left door leaf and the right door leaf through hinges unlike the traditional door leaf, and the installation and the maintenance are more convenient. The right door leaf 7 is welded with a door opening sensing plate 701 and a door closing sensing plate 702. In the same way, the function principle of the left door leaf 5 is the same as that of the right door leaf 7.
The action sequence of the miniature automatic fireproof door is as follows:
under the normal condition, the left door leaf and the right door leaf are both in a closed state, the track penetrates through the reserved I-shaped space of the door leaves and is continuously erected, the indicator lamp 24 flashes orange warning in the opening and closing processes, and green flashing is displayed after the action is finished. When the rail robot works and runs to the fire door and needs to pass through the fire door (the action sequence is the same from any side of the two sides of the door), a door opening instruction is sent to the background, the automatic fire door controller 13 (the left and right two motors 15 share one controller 13) receives the door opening instruction, the driving motor 15 of the right door 7 rotates clockwise first to drive the gear 17 to rotate in the same direction, the gear 22 meshed with the gear rotates anticlockwise, the gear 22 can drive the connecting shaft 8 connected with the gear through the spline to rotate in the same direction around the bearing 10, and the connecting shaft 8 drives the right door 7 fixed with the connecting shaft through the bolt 703 to move in the same direction to open the right door 7. When the right door leaf driving motor 15 is delayed for 400ms after acting, the driving motor positioned in the left door frame 1 starts to act, and the left door leaf 5 is driven by the motor to rotate and open according to the same principle. As shown in fig. 3, when the door opening sensing plate 701 slides into the opening sensing area of the position sensor 19, and detects that the door has been opened by 90 ° at the limit position, the motor stops operating, and the right door leaf is completely opened; similarly, the door opening sensing plate 501 on the left door leaf 5 enters the opening sensing area of the sensor 19 in the left door frame 1, and then the motor stops. By sequentially opening the doors so far, the track robot passes through the firewall along the track through the opened space.
After the track robot passes through, the controller 13 receives a door closing command, at this time, the motor located in the left door frame 1 first acts, the motor 15 located in the right door frame starts to act after delaying 400ms, namely, the doors are sequentially closed when being closed, and interference of two door leaf occlusion parts in the door opening and closing process is prevented. When the door is closed, the rotation direction of the motor is opposite to that of the door when the door is opened, and the door leaves are driven to be closed in sequence through the driving gear and the driven gear. As shown in fig. 4, when the door closing sensor plate 602 and the door closing sensor plate 702 enter the corresponding position sensor 19, the motor stops operating, and the door closing is completed.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
