Electric power storage type linear retractable door

Abstract

The invention discloses an electric power storage type linear retractable door. The electric power storage type linear retractable door comprises a main door column, a secondary door column, a door body and a machine head; one end of the door body is connected with the secondary door column, and the other end is connected with the machine head; the machine head includes a walking mechanism and a motor; the motor drives the walking mechanism to perform a reciprocating motion along a connecting line of the main door column and the secondary door column; an accumulator and a charging contact are arranged in the machine head; the charging contact is positioned on the surface of one side, towards the main door column, of the machine head, and is electrically connected with the accumulator; the accumulator is electrically connected with the motor; the motor is a direct-current motor; the main door column is provided with a power supply contact plate opposite to the charging contact; and the power supply contact plate is electrically connected with an external power supply. The electric power storage type linear retractable door gets rid of a necessary power supply drag chain in a traditional design to prevent the possibility of hurting people due to electricity leakage caused by quick aging of a power supply wire in an outdoor environment or or repeated folding working environment.

Description

technical field [0001] The invention relates to the technical field of barrier doors, in particular to an electric storage type linear telescopic door. Background technique [0002] The linear retractable door includes a main door post, an auxiliary door post, a door body, and a machine head. One end of the door body is connected to the auxiliary door post, and the other end is connected to the machine head. The machine head includes a traveling mechanism and a motor, and the motor drives The traveling mechanism moves in the forward or reverse direction, driving the machine head to reciprocate along the line connecting the main gate post and the auxiliary gate post, thereby controlling the extension and contraction of the door body. Existing linear retractable doors all adopt 220V commercial power to supply power to the motors, and the power lines are arranged along the door body, and are connected to the machine head by the auxiliary door posts. Since the linear retractabl...

Problems solved by technology

Since the linear retractable doors are mostly located outdoors, the power cord has high requirements on the weather resistance of the environment; the door body is often stretched, so that the power cord is often folded, which is prone to damage, resulting in electric leakage and injury accidents; The door will stop working when there is a sudden power failure in front of you, and you can only rely on manpower to push the door body back and forth to open and close the door
