Abstract

The invention discloses an automatic opening and closing device for an air-tight door. The automatic opening and closing device comprises a first hydraulic driving assembly, and a locking mechanism, wherein a hydraulic cylinder of the first hydraulic driving assembly is connected with a fixed object, a piston rod of the first hydraulic driving assembly is connected with the air-tight door, and thefirst hydraulic driving assembly is used for driving the air-tight door to move so as to achieve opening and closing of the air-tight door; and the locking mechanism comprises a second hydraulic driving assembly and a rotary locking assembly, and the rotary locking assembly comprises a gear disc, a cross rod and a rack. The automatic opening and closing device for the air-tight door can achieve automatic remote control, is safe and reliable, improves safety and reliability, and achieves remote automatic operation; and the automatic opening and closing device for the air-tight door achieves remote opening and closing of the pump room air-tight door, fills the industry blank, and greatly improves safety and reliability.

Description

Technical field [0001] The invention relates to the technical field of closed doors, in particular to an automatic opening and closing device for closed doors. Background technique [0002] The drainage system of a mine is an important manifestation of the ability to check disaster resistance. At present, most mines have achieved remote control of water pumps, while the remote control of closed doors of pump rooms and substations is still in a blank stage. The airtight door is used in the passage from the underground main substation and the main drainage pump house to the underground yard, and it is easy to close to prevent the sudden intrusion of water. The closed door leaf is made of flat steel plates, well-shaped ribs, ring beams, etc. The door frame is a channel steel and I-steel combined frame structure. The tightening device is a wedge-shaped slider wedge. The hinge is supported by rolling bearings. A closed door is a door that can increase air tightness. The materials...
