The sun rising ring electric telescopic door is mainly composed of door body, driver and control system. The door body of the telescopic door is made of high quality aluminum alloy and ordinary square pipe, and is hinged by parallelogram principle. The telescopic and flexible stroke is large. The driver of the telescopic door is driven by a special motor. The worm and worm gear reduces speed and is equipped with a manual clutch. When the power is cut off, the telescopic door can be opened and closed manually. The control system has a control board, a button switch and a wireless remote control device according to the user's needs.
The motor used in the electric expansion door is a special turbine worm type motor, because of its special transmission principle, high stability, high output torque, low noise, moderate speed.
The electric expansion door mainly consists of three parts: telescopic door body, nose and controller.
1. Telescopic door body: The telescopic door body is composed of large frame, cross brace, shaft (fixed shaft, sliding shaft) and door body wheel. The whole door body is metal structure, which is divided into stainless steel door body, aluminum alloy door body and die-casting aluminum door body according to material quality.
2. Head: It is composed of driver and electric part. It is fixed at one end of the door body to drive the door body to stretch and shrink, and it is used with the door body.
The driver is divided into general and robot type.
3. Controller: composed of control box, desktop controller and handle remote controller.
1), control box: fixed in the head, it receives the instructions issued by the controller to control the operation of the door body.
2) desktop controller: it is mainly used by duty personnel in duty rooms.
3) Handle remote control: mainly equipped with vehicles to use, can be around the nose within 10-30 meters (depending on the scene of radio communication environment) to control the opening and closing of the door.
Structural characteristics:Stainless steel adopts international standard stainless steel raw materials, through special process pipe bending welding finalization made of door body. The door body is permanent and durable. The door body is connected by connecting rods of large and small size to form a telescopic door. The connecting type of Dalian rod is ancient coin and plum blossom type. The small connecting rod is connected into a diamond type road gate, which is beautiful and elegant, and is firm and durable.
Features of stainless steel expansion door movable part: each movable part of the expansion door is assembled with stainless steel pipe, axle, bush, stainless steel nut and nylon pad, and each link is filled with advanced lubricating oil, no noise and flexible.
The main structure of aluminum alloy electric expansion door is similar to stainless steel. It is also made of standard aluminum alloy profiles directly pressed by mold and then connected by galvanized pipe and cross connecting rod according to the movement principle of parallelogram. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful, and the corrosion resistance is more.
Track type of electric telescopic door:In the early days, electric steel doors were generally constructed with triangular steel double track, which was difficult to construct and required high road surface. With the continuous updating of technology, the two tracks have been eliminated.
The main orbit modes on the market are monorail and trackless two. Monorail is to fix a solid square steel or light rail with expansion bolt on the road surface (light rail laying requirements are higher, but the service life is longer, using more), so as to guide and resist the wind electric door; Trackless is to lay hidden magnet on the road surface, the door body in operation according to the bottom of the induction system to automatically navigate.
There are two common ways of controlling electric translational doors:
1, control handle, line control;
2, wireless remote control, common 433MHz wireless remote control handle control;
With the development of information technology, more and more external system control methods are used, such as automatic release system of electric door through embedded control system or computer control, computer automatically identify the vehicle number plate, automatic door opening.
Maintenance method of electric telescopic door：
1. Correct usage
In use, the movement should be as light as possible to open the light shutter, do not force too large and too violent; Electric expansion door open, found to be hindered, should first troubleshooting. High grade electric telescopic doors with internal open windows, folding electric telescopic doors and so on shall be strictly operated according to instructions.
2. Frequent cleaning
Frequent cleaning, keep the surface clean, when scrubbing as much as possible to choose soft gauze or cotton silk, so as not to scratch the surface of the electric expansion door. When there are stains and dirt, wash with clear water, alcohol or neutral detergent
Try to avoid contact with acidic and alkaline chemicals on the surface of aluminum alloy electric telescopic door.
4, hardware maintenance
Check all kinds of hardware fittings of electric telescopic door regularly, if it is found that there is damage, repair or replace them in time, the hardware is used for a long time, can be coated with a little paraffin oil or drip some oil, reduce friction, keep the opening and closing of electric telescopic door easy and flexible. The sealing wool and glass tape of electric expansion door are the key parts of sealing and heat preservation. If there is aging and loosening, they should be replaced in time.
