Light high-strength automatically controlled protective door

Abstract

The invention discloses a light high-strength automatically controlled protective door, comprising a door leaf, a door frame, a closed lock, a hinged leaf and a door leaf driving device. The door leaf comprises a door leaf arch plate, a rib plate, a reinforced grate, an inner arch plate, an arch corner and a pulling plate, wherein the door leaf arch plate and the pulling plate are made of light composite materials; the rib plate, the reinforced grate, the inner arch plate and the arch corner are made of steel or aluminium alloy; the inner arch plate is tightly appressed to the back of the door leaf arch plate; the rib plate and the reinforced grate are fixedly connected with the back of the inner arch plate; the arch corner is fixedly connected with left and right side edges of the door leaf arch plate and the inner arch plate; the pulling plate is fixedly connected with the backs of the rib plate and the reinforced grate; and left and right sides of the pulling plate are wrapped on the outer side surface of the arch corner. By means of the protective door, the technical problems that the traditional electric control protective door has a heavy door body, is difficult to convey, install and debug and has a complex driving mechanism and low reliability can be solved. The protective door has the advantages of high resistance, light and convenient door leaf, small occupation space of a driving system, convenience for installing and debugging, simple and rational integral structure, and convenience for operation and maintenance.

Description

technical field [0001] The invention relates to an electric control protective door used in protective engineering. Background technique [0002] The command protection project is an important part of the national defense system. It has a strategic deterrent effect in peacetime and can guarantee the safety of important national personnel, command organs and strategic counterattack forces in wartime. The current form of war is mainly based on local and rapid strikes, which require projects to have high protection capabilities and rapid response capabilities. However, most of my country's command and protection projects were built in the 1960s and 1970s. Most protective doors are made of concrete or steel structures, which are bulky overall and difficult to transport, install, and debug. Therefore, the design of the electric drive mechanism is more difficult, and the electronic control system of the existing electronically controlled protective doors uses mechanical transmissio...
