Description

Technical Field

[0001] The invention relates to the technical field of manipulators, in particular to a novel fireproof iron door. Background Art

[0002] During mine construction, the air inlet should be equipped with fireproof iron doors. The fireproof iron doors must be tight and easy to close. When opened, they must not hinder lifting, transportation and personnel passage. They must also be maintained regularly to ensure safety in the event of fire or explosion.

[0003] The existing Chinese patent application with application number CN117605390A discloses a telescopic fire door that can be remotely monitored, including a door frame, a telescopic mechanism is arranged inside the door frame, and the telescopic mechanism includes two groups of threaded rods, a connecting plate 1, multiple transmission rods 1 and multiple transmission rods 2, the two groups of threaded rods are rotatably connected to the inner wall of the door frame, the top ends of the two groups of threaded rods are fixedly connected with bevel gear 1, and the two ends of the connecting plate 1 are fixedly connected with threaded blocks; this invention, through the coordination arrangement between the telescopic mechanism, the double-axis forward and reverse motor, the bevel gear 2 and the door frame, can make the device have a telescopic function, thereby effectively avoiding the situation that the door cannot be retracted when not in use due to the lack of telescopic function, which not only ensures that people can travel more conveniently when not in use, but also effectively saves the space occupied by the door when not in use.

[0004] However, the fireproof iron door has the following defects when used:

[0005] 1. When the existing fireproof iron door is installed at the corresponding location (mine construction) for assembly and use, it is difficult to open and close the ordinary fireproof iron door due to the large negative pressure at the mine air inlet. If the fireproof iron door is too thin, it will be easily sucked flat, causing air leakage and damage to the iron door and making it inoperable. If it is too thick, it will cause problems such as inconvenience in opening and closing, which has great limitations.

[0006] 2. When sealing the door frame, the existing fireproof iron door generally adopts the method of rolling shutter retracting and unrolling to realize the opening and closing of the rolling shutter door. However, when the above rolling shutter door is actually operated, the negative pressure generated inside the mine will absorb the rolling shutter door, which will cause certain gaps in the side wall and bottom of the rolling shutter door, and the blocking and sealing performance of the flame or hot air generated by fire or explosion are poor, and the safety is low.

At the same time, when the main shaft rotates, it will also drive the gears and another set of retracting drums connected to its side to rotate, automatically realizing the unwinding operation of the outer wire rope of another set of retracting drums, ensuring that there will be no conflict and interference when the vertical baffles are stretched to unfold and move horizontally. The multiple sets of vertical baffles after unfolding can cooperate with the horizontally arranged T-shaped baffles to stably and firmly support and protect the rolling door panels arranged on their sides, reducing the problem of the rolling door panels being sucked flat due to the negative pressure generated in the mine.

[0049] 2. In the new fireproof iron door, the smoke alarm, multiple limiters and trigger modules can be designed so that when a fire or explosion occurs, the smoke generated will trigger the smoke alarm and automatically start the deflection motor to operate, automatically driving the T-shaped barrier rod to rotate and contact the side of the trigger module. The trigger module then sends a signal to start the speed regulating motor to operate, realizing the deployment of multiple sets of vertical barrier rods. At the same time, after the vertical barrier rod moves to the corresponding position, it will trigger the limiter to operate, send a signal to the retractable motor to operate and drive the rolling door panel to unwind, thereby realizing automated fire prevention operations and more intelligent operation;

[0050] 3. In the new fireproof iron door, after the rolling door panel is rolled up and unrolled, the servo motor can operate to drive multiple sets of tension rods to move inward or outward at the same time, and squeeze and resist the unrolled rolling door panel, so that the unrolled rolling door panel will not loosen, and the connection between the rolling door panel and the iron door base will not have a large gap due to looseness, and the generated smoke and flames will not leak along the gap, which will provide better sealing and higher safety for the mine. At the same time, the design of the extrusion spring can ensure that the moving tension rod and the oblique slider can always resist the side of the raised part, so that the tension force can be adjusted by the forward and reverse rotation of the servo motor;

[0051] 4. In the new fireproof iron door, the T-shaped barrier rod that supports and protects the rolling door panel can be in the longitudinal position when not in use. Multiple groups of vertical barrier rods can be uniformly moved to the inside of the iron door base when not in use. The rolling door panel can be retracted into the inside of the rolling cylinder when not in use, ensuring that the above structure will not block the normal construction work of the workers when not in use.

[0076] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0077] See also Figure 1-Figure 12 A novel fireproof iron door comprises an iron door base column 10, a transverse beam 20, a retractable windshield mechanism 30 and an expandable rolling shutter mechanism 40. The iron door base column 10 is provided with two groups, and a transverse beam 20 is installed between the two groups of iron door base columns 10. A retractable windshield mechanism 30 extending to the inside of the transverse beam 20 is installed on the side of one group of iron door base columns 10. The retractable windshield mechanism 30 extends between the two groups of iron door base columns 10. An expandable rolling shutter mechanism 40 extending to the outside is arranged inside the transverse beam 20. The expandable rolling shutter mechanism 40 is located on the side of the retractable windshield mechanism 30. The rolling shutter door plate 400 rolled up by the expandable rolling shutter mechanism 40 extends between the two groups of iron door base columns 10. The retractable windshield mechanism 30 comprises a retractable and reeling assembly 50. The retractable and reeling assembly 50 is installed on the side of a group of iron gate base columns 10, and two groups of steel wire ropes 500 are wound inside the reel-up assembly 50, and the steel wire ropes 500 extend to the inside of the transverse beam 20; a windshield rod stretching assembly 60, the windshield rod stretching assembly 60 is movably connected to the inner bottom of the transverse beam 20, the windshield rod stretching assembly 60 is connected to the two groups of steel wire ropes 500, and the bottom of the windshield rod stretching assembly 60 extends between the two groups of iron gate base columns 10, the windshield rod stretching assembly 60 is in contact with the side of the deflection beam assembly 70, and the deflection beam assembly 70 is installed on the inner bottom of a group of iron gate base columns 10, wherein a smoke alarm 100 is installed on the side of one of the iron gate base columns 10, and a limiter 600 is provided on both the left and right sides of the windshield rod stretching assembly 60.

[0078] The above working principle: When the expansion roller shutter mechanism 40 unwinds the roller shutter door panel 400 to achieve the sealing operation of the gap between the two groups of iron door columns 10, the deflection beam assembly 70 is first started to operate and the horizontal beam is rotated between the two groups of iron door columns 10. Then the retracting and unwinding assembly 50 operates to drive multiple groups of vertical beams to move horizontally to block and cover the gap between the two groups of iron door columns 10. When the above operation is completed, the expansion roller shutter mechanism 40 is started to operate to drive the roller shutter door panel 400 to unwind. At this time, the roller shutter door panel 400 is in contact with the side of the windshield rod stretching assembly 60. The windshield rod stretching assembly 60 can be used to protect the roller shutter door panel 400 to prevent the negative pressure of the mine from damaging the roller shutter door panel 400 and improve the strength of the roller shutter door panel 400. At the same time, after the expansion roller shutter mechanism 40 is operated, the rolling roller shutter door panel 400 can be supported and positioned to reduce the problem of gaps between the rolling roller shutter door panel 400 and the iron door base column 10 caused by the negative pressure generated in the mine.

[0079] In the present invention, the smoke alarm 100 can sense the smoke and flames generated by fire or explosion, and automatically start the windshield retractable mechanism 30 and the expansion shutter mechanism 40 to operate, thereby realizing an automated sealing operation. The design of the stopper 600 can sense the position of the windshield rod stretching assembly 60 in the retracted state, and can automatically perform various steps and processes of the fireproof iron door of the present invention in sequence.
