Abstract

The invention discloses a coding controllable two-way balance banister. The banister comprises a counter rotating motor, a speed reducer component, an output shaft, and a braking lever and a chassis which are arranged on the output shaft. The banister is characterized in that the motor and the speed reducer are connected with the output shaft through a crank link mechanism; the crank link mechanism is connected with a first spring and a second spring which play a role of two-way balance; the motor and a speed reducer rotary shaft of the speed reducer component are provided with a coder which performs accurate positioning on the positions moved by the braking lever; and the banister also comprises a transducer which is matched with the coder to adjust the speed of the motor. The banister can perform accurate positioning on positions moved by the braking lever and perform frequency conversion control on the speed of the motor, so as to ensure smooth operation of the braking lever and effectively save energy.

Description

【Technical field】

[0001] The invention relates to a barrier gate for the management of parking lots, entrances and exits of residential quarters, and exits and entrances of expressways, in particular to a coded-controllable two-way balanced barrier gate which can make the gate run smoothly and save energy. 【Background technique】

[0002] At present, with the popularization of family cars, the management of vehicles is also increasingly concerned by people. In order to manage vehicles scientifically and effectively, automatic control gates are installed at the entrances and exits of parking lots, residential quarters and many public facilities in cities, and IC cards are used to manage the timing, billing, and release of vehicles entering and leaving. After the vehicles entering and exiting the parking lot or residential area take or swipe the card, the barrier gate will automatically open, and the gate lever of the barrier gate will rotate upward from the horizontal position...
