Electrically controlled heavy protective door

Abstract

The invention relates to an electrically controlled heavy protective door, and belongs to the technical field of protective equipment. The electrically controlled heavy protective door comprises a door frame and a door leaf, wherein the door frame and the door leaf are connected through hinge pages, the door leaf is provided with a locking system, and hand wheels are arranged on the two sides of the locking system; the electrically controlled heavy protective door is further provided with a torquer, the torquer comprises a torque motor and a planetary reducer, wherein the output end of the torque motor is connected with the planetary reducer, and the output end of the planetary reducer is connected with at least one of the hinge pages for controlling opening and closing of the door leaf; the torque motor is further arranged on one side of the door leaf, a chain wheel I is arranged on an output shaft of the torque motor, meanwhile, a chain wheel II is arranged on a transmission shaft which is connected with the corresponding hand wheel as well, and the chain wheel I and the chain wheel II are connected through a chain or a gear in a transmission mode; and the door leaf adopts a caststeel arched structure and is used for resisting high strength shock waves. According to the electrically controlled heavy protective door, the problems of large hand power and resistance due to self-locking of the reducer or large drag during the manual operation are effectively solved.

Description

technical field [0001] The invention relates to a protective door, in particular to an electric-controlled heavy-duty protective door, which belongs to the technical field of protective equipment. Background technique [0002] Protective doors are used in key protection projects to resist blast shock waves. But existing protective door, because door body is heavier, often mainly is manual mode, and when manual, it needs to increase bigger manual power because of reducer self-locking or big resistance, is not easy to manually open. Simultaneously, existing protective doors are less resistant to shock waves because they generally adopt plate-type plane structures, which requires either thicker door designs or high-strength materials, which indirectly increases the cost of protective doors. CN109440816A discloses a kind of composite material civil air defense protection equipment for the hoisting port of urban underground comprehensive pipe gallery, including equipment door le...

AI Technical Summary

Problems solved by technology

Although the above structure is driven by hydraulic pressure, it still has the problems of high opening resistance, slow opening speed and insufficient resistance to shock waves for heavy-duty protective doors.
