Automatic retractable door by a retractable door body, the head, the controller consists of three parts. Automatic retractable gate body: retractable door is a large box by the door, cross bracing, axis (fixed axis slide axis) and telescopic retractable door door door body round the main components. Retractable door body as a whole is a metal structure, the material is divided into the stainless steel door, aluminum alloy door, die-cast aluminum door. 2, the nose: the drive and the electrical part composition, it is fixed at one end of the retractable gate body, driving the telescopic movement of the door body, with retractable door body supporting the use. Drive sub-ordinary wire, Luxury full remote control and intelligent robots trackless type. 3, controller: control box, desktop controller and handle the remote control. 1), the control box: fixed received by it in the nose, the directives issued by the controller to control the operation of the automatic retractable door. 2), the desktop controller: mainly by the staff on duty in the duty room. 3) handle the remote control: with vehicle use, at within the nose around 10-30 meters (according to the on-site radio communication environment) activities to control automatic retractable door opening and closing. Finally - Qingdao automatic retractable door of the main technical parameters 1, Product conventional height: 1600mm 2, Ambient temperature: -500 - 750 3, air relative humidity: ≤ 90% 4 Insulation: Grade B 5, transmission speed ratio: 1:40 electric retractable door installation steps: 1. determined to convey the position of the indoor control box, that manipulate the the retractable door switch device location; 2. 220V power supply leads to the position of the lower end of the control box, the best with a ground wire, the thickness of Specifications for 1.37, but leakage protection devices, and PVC Concealed; 3. reserved ￠ 32mm PVC piping, from the position of the lower end of the control box down to below ground level, out through the wall, to track the approximate location of the ground plane under 0.1 -0.15 m for later the retractable door outdoor lines burglary. Drawn in accordance with the above table the openings length, puzzle doorway hole wide clearance of not less than 0.75-0.8 meters the net ordinary size door within the height of not less than 0.25 m door height, luxury door is not less than 0.1 m door height; openings upper end of the stay end side and 0.4 meters wide, 0.6 meters high and manholes conditional doorway total length plus 0.2-0.3 meters long, this may change the manhole small door, and to facilitate future maintenance maintenance retractable door electrical wiring; 2. before laying track in addition to leaving about 0.8-0.9 meters wide, the first to do a good job on both sides of the ground; 2-3 (winter 5-7), the re-laying of the track at the same time, civil tie do good track at the ground, pay attention to the laying of the track during road closed to traffic, so as not to bend the track; http://www.qddcmy.com
