The internal structure of the retractable gate
Retractable gate
We are common in our daily life, but do you know the internal structure of the retractable gate? The following retractable gate manufacturers Anda gate industry Anda small series for everyone to introduce the internal structure of the retractable gate
Telescopic gate motor is a permanent magnet, bipolar DC motor, the motor is equipped with internal slowdown device. The interior of the telescopic gate motor is generally equipped with an anti-radio dry device to prevent interference with the reception of radio in the vehicle when using a glass lifter. The motor is also equipped with internal current protection device, the motor movement is blocked when the power can automatically cut off, so as to avoid the motor burned. Telescopic gate motors are generally designed to operate in positive and negative rotation, with high output torque, low noise, small size, flat shape and short working hours, and dust and detergent with sealing performance.
In order to match the structure of the different lifts, the structure of the output part of the telescopic gate motor is also different. For the sheave structure, the output part of the motor is a plastic sheave with a rope on the sheave and a rope on the rope. The motor drives the sheave, which drives the rope to be wound, and the slider on the wire rope drives the glass to move up and down along the guide rail. For the arm-type structure, the output part of the motor is also a pinion gear, by engaging with the teeth on the flexible shaft (similar to the rack), driving the flexible shaft winding, driving the glass along the rail for up and down movement.
Retractable gate glass lifter with hydraulic and mechanical two categories. Mechanical lifter structure of the type of rope wheel, cross arm and soft shaft type.
(1) electric hydraulic glass lifter. Electric hydraulic retractable gate glass lifter by the motor, cylinder, with arms and control switches and other components. If you want to raise a window glass, press the window up button, the circuit is connected, the current flows into the motor, turn the pump to produce high pressure oil. At the same time the current flow into the control of the window of the electromagnetic coil, the valve open, the pressure oil into the cylinder will push the piston, the connecting device, so that the windshield rose. If you want to reduce a window glass, press the window down button, the electromagnetic coil has a current into the valve to open, then the motor does not turn, no pressure oil, windshield connecting rod by the spring force, the oil pressure The oil in the tank returns to the oil storage chamber, causing the windshield to drop.
(2) Rope-type retractable gate glass lifter. Rope-type retractable gate glass lifter consists of pulleys, wire rope, tensioners, tension pulleys and other components by driving the motor by pulling the rope to control the expansion and contraction of the gate glass, the output part of the motor is a plastic sheel, sheave on the rope , The rope is equipped with a slider, the motor drive rope, driven wire rope winding, rope on the slider to drive the glass, so as to move up and down along the guide.
(3) cross arm retractable gate glass lifter. Six window glass lifter, mainly by the fan-shaped tooth plate, glass rails and regulators and other components. Its working principle is: fan-shaped tooth plate using the drive motor ratchet to rotate, so as to drive the X arm movement, leaving the windshield for moving up and down.
In general, the internal structure of the retractable gate is as described above, and the actual expansion of the gate and not much difference. Different should be manufacturers in the design of the retractable gate will be more prominent when their product features and attached to some of the special configuration, in order to achieve special features.
