The utility model has the advantages of high-speed response, abnormal agile and quick reaction.

Description

Retractable door gate inhibition's control device

Technical field

The utility model relates to the retractable door gate inhibition's controlling organization on a kind of automatic ticket checking gate that is used for automatic ticket-selling system and track traffic turnover station.

Background technology

Development along with computer electron electric power and sensor technology, each advanced country's electromechanical integrated product emerges in an endless stream, and many class products such as all kinds of door machineries, printing machinery, metallurgical machinery, chemical machinery and industrial robot, intelligent robot all have new progress every year.Electromechanical integration technology more and more receives the concern of each side, and it is being improved the people's livelihood, increases work efficiency, energy conservation, reduction material consumption, is strengthening aspect such as enterprise competitiveness and play great effect.

At present, the fan door dynamic resistance mechanism on automatic ticket checking gate, that often uses has triadius type stopper and door leaf formula stopper two big classes.Because door leaf formula stopper has People's Bank of China by fireballing characteristics, has obtained extensive utilization on the automatic ticket checking gate of rail traffic station.Door leaf formula stopper is divided into the vertical shaft rotation and pats three types at door, flexible translation door, transverse axis swing fan door etc.; Can not bounce back automatically when wherein the greatest drawback of beating door and translation door is outage, be disadvantageous to promptly dredging the stream of people, and the utility model improves this.

Summary of the invention

For solving aforementioned problem of patting door and translation door existence, the utility model provides a kind of retractable door gate inhibition's control device, its scheme is, door is installed on door bracket, main shaft is passed through in the door bracket lower end, be fixed on the bracket base, door bracket one side is installed an iron block, one push rod also is fixed on the bracket base by main shaft, fix an electromagnet on the push rod, electromagnet is inhaled mutually with the iron block on the door bracket, and door bracket and push rod are combined, connect a connecting rod on the push rod, connecting rod is connected with rocking arm by rotating shaft, and rocking arm is connected with gear by shaft tip, and gear just is being subjected to a motor drives, reverse rotation, door is shunk to the right or stretch out left, door shrinks or stretches out by two limit sensors controls.

In the rotating shaft of door bracket torsion spring is installed, under off-position, electromagnet loses magnetism, and makes door bracket break away from push rod, and by the torsion of torsion spring, forces door bracket to shrink left and reaches the outage purpose of opening the door.

Described limit sensors is to transfer at door bracket a baffle plate is installed, two screws are installed on the baffle plate, corresponding respectively two sensors that are installed on the door bracket base, sensor is connected with motor control panel, and when door reached extreme position, a screw was near a sensor, the shutdown of sensor signal control motor, when door was retracted to extreme position, another screw was near another sensor, and sensor signal control motor shuts down.

The utility model has the advantages that:

1, high-speed response and since directly cancelled in the system some responsive time constants bigger as mechanical transmissioning pieces such as leading screw, belts, whole closed loop border control system dynamic response performance improved greatly, abnormal reaction is sensitive quick.

2, precision height, the lever actuated system has cancelled the driving error that causes owing to mechanical mechanisms such as leading screws, the tracking error that has lagged behind and brought because of transmission system when having reduced interpolation.Detect FEEDBACK CONTROL by lever positions, can improve the positioning accuracy of a machine greatly.

3, dynamic stiffness height, because " lever actuated ", the motion delay phenomenon that has caused because of elastic deformation, fretting wear and the backlass of middle transmission link when having avoided startup, speed change and commutation has improved its transmission stiffness simultaneously.

4, speed is fast, the acceleration and deceleration process short, because torque motor has 100% working environment and constant torque output, in conjunction with the flexible door-plate of single lever control.This brings the motion of speed-controllable, soft terminal point location and dynamic brake function.Lever can be regulated the lock door plate in make position, or applies the open state that keeps door-plate after the specific power.Also because the high-speed response of above-mentioned part transmission shortens its acceleration and deceleration process greatly, moment reach at a high speed when realizing starting, again can moment during high-speed cruising standard stop.

5, intelligent sucker is installed in the appropriate location of a machine, when the people is in retractable door pass closed region, can stop the closure of door, and the power of closing meets relevant regulations less than 150Nm, and therefore the injury to the people almost is impossible.
