Manual and electric dual-purpose double-leaf flat opening vertical hinged arched protective door and control method

Abstract

The invention discloses a manual and electric dual-purpose double-leaf flat opening vertical hinged arched protective door and a control method. The protective door comprises door leaves, a door frame, a lifting doorsill and an executing mechanism. The door frame is fixed to a wall body, the lifting doorsill is arranged at the bottom of the door frame and cooperates with the door leaves, the doorleaves are connected to the door frame through hinges, and the actuating mechanism is arranged on the door leaves. On the structure, the lifting doorsill is arranged to cooperate with the arched protective door, a double-control supporting mechanism is arranged to achieve effective protection and impact resistance of the protective door, the protective door is flushed with the ground in daily useto meet the walking requirement, the protective door is lifted to cooperate with the door leaves in emergency to achieve the protection function, and the function of bearing and decomposing impact isachieved; and on control, the manual-electric double-control executing mechanism is arranged, a corresponding control method is set to achieve electric control or manual control opening and closing ofthe door leaves, convenience of daily use and emergency opening and closing under emergency conditions are met, and it is guaranteed that the protective door can be effectively opened and closed under any condition.

Description

technical field [0001] The invention relates to the technical field of airtight protective doors, in particular to a double-leaf flat-opening vertical-turning arched protective door for both hand and electric use and a control method. Background technique [0002] The entrances and exits of civil air defense buildings or facilities need to be equipped with airtight protective doors to realize the protective function in wartime. The double-leaf arched protective doors are mostly used at the entrance of civil air defense projects with high resistance levels, and the performance requirements for airtight protective doors are relatively strict. , It is required to have sealing and strong impact resistance to achieve the protective effect. Most of the existing airtight protective doors adopt the method of increasing the size and thickness of the steel plate or the door leaf enhances the protective effect, which makes the door leaf have the problems of self-heavy, inconvenient ope...

AI Technical Summary

Problems solved by technology

Most of the existing airtight protective doors adopt the method of increasing the size and thickness of the steel plate or the door leaf enhances the protective effect, which makes the door leaf have the problems of self-heavy, inconvenient opening and closing, cumbersome opening and closing, and time-consuming and labor-consuming problems, resulting in the normal protective door. It takes a lot of time to open and close once, and in order to ensure that the door leaf can be opened and closed normally under any circumstances, the opening and closing control method is strictly required; at the same time, the door leaf with a large self-weight is prone to creep and sinking at the far end. It often leads to the contact between the far end of the door leaf and the ground, resulting in the failure of the door leaf to open and close normally, resulting in the failure of the door leaf to play a protective role

And in general, in order to enhance the protective effect, a threshold is set up to improve the airtight effect and impact resistance. Now the threshold set up is generally a fixed threshold or a lifting threshold, but there are many defects in the fixed threshold. For example, the fixed threshold is not conducive to the entrance. The entry and exit of all vehicles, personnel and materials. Therefore, in order to improve the usual use effect and convenience, the lifting threshold is often used.

At present, the commonly used lifting thresholds in civil air defense projects are hydraulic lifting thresholds, but the hydraulic lifting thresholds have the disadvantages of large space required by the lifting mechanism, high price, and hidden dangers of leakage. The existing airtight protective doors cannot effectively cooperate with the lifting thresholds. protective effect
