Labor-saving wing gate with function of automatically opening door in case of power failure

Abstract

The invention discloses a labor-saving wing gate with the function of automatically opening a door in case of power failure, which comprises a case provided with a rack, wherein a guide rail is arranged on the front side of the rack; a wing plate, wherein the side, opposite to the rack, of the wing plate is fixedly connected with a guide wheel; a driving mechanism is arranged in the case and used for driving the wing plates to swing outwards out of the case or retract inwards; a power-off switching-off mechanism comprises a traction rope, an electromagnet attraction piece, a large gravity block arranged on the electromagnet attraction piece and an electromagnet installed below the bottom end of the guide rail; when the wing gate is powered on after being powered off, the wing plate swings outwards out of the machine box, the electromagnet attraction piece is synchronously driven by the traction rope to move upwards to make contact with the electromagnet, the electromagnet is powered on, when the wing gate is powered off after being powered on, the electromagnet is powered off, and the large gravity block drives the wing plate to retract inwards into the machine box through the traction rope. The invention has the beneficial effects of automatically opening the door and closing the gate without effort when power is off.

Description

technical field [0001] The invention relates to the technical field of gate equipment. More specifically, the present invention relates to a labor-saving flap gate with the function of automatically opening the door when the power is off. Background technique [0002] Wing gates, one of the channel management equipment, are mainly used for pedestrian channel management. They have the characteristics of quick opening, safety, and convenience. They are ideal management and dredging equipment for high-frequency pedestrian access. It has been widely used in airports, subway stations, stations, docks, scenic spots, parks, student dormitories, unit pedestrian passages, etc. It can cooperate with smart cards to realize the function of off-line ticketing management system and form unattended management of personnel entry and exit. For fire protection, the wing gate is required to have the function of automatically opening the power-off channel to avoid blocking people. The existin...

Problems solved by technology

[0004] Another object of the present invention is to provide a labor-saving wing gate with the function of automatically opening the door when the power is off. Through the large gravity block and the setting of the traction rope, the electromagnet, and the electromagnet suction piece, it can solve the existing problem of meeting the power-off gate opening function. The wing gate has the problem of overcoming the work done by the existing elastic device during the closing process of the gate and when it is closed.
