Device capable of automatically opening and closing cabin door in compact cabin body

Abstract

The invention discloses a device capable of automatically opening and closing a cabin door in a compact cabin body. The device comprises a cabin door frame and a cabin door which are arranged on the cabin body, wherein the cabin door is connected with a cabin door opening and closing driving device; the cabin door opening and closing driving device comprises a motor base, a driving motor and a rope traction device; the rope traction device comprises a traction steel wire rope, a cabin door opening and closing controller, a rope tension mechanism and a cabin door opening and closing potentiometer; a second angular displacement sensor is arranged on the cabin door opening and closing potentiometer; the rope tension mechanism comprises a rope tension potentiometer and a tension guide wheel; the rope tension potentiometer comprises a rope tension potentiometer base and a rope tension potentiometer swinging arm; a first angular displacement sensor is arranged on the rope tension potentiometer; and a cabin opening and closing controller is used for automatically controlling the running of the driving motor according to data fed back by the first angular displacement sensor and the second angular displacement sensor. Due to the adoption of the device, the problem of opening and closing of the cabin door in a compact cabin body is solved, and the phenomena of possible blocking, falling of a steel wire, and the like in the entire moving process are avoided.

Description

technical field [0001] The invention relates to a cabin door opening and closing device, which belongs to the field of automatic cabin door motion mechanism design and control methods. Background technique [0002] Chinese patent CN201020559726.6 discloses a compartment or vehicle-mounted cabin and its automatic opening and closing hatch.
