[0002] Barriers are channel management devices used for various entrances and exits, and are now widely used at the entrances and exits of highways, parking lots, communities, enterprises and institutions, etc. As the use scenarios of barriers continue to expand, for some dual-channel scenarios that require temporary unilateral closure or temporary flow restriction / diversion (such as highway forks, left and right roads, and roadside confluence / exit, etc.), under the premise of giving priority to driving space, the installation location and floor space of the barrier are very high, and the control of the roads on both sides must also be taken into account.

[0003] The barriers currently on the market still have some shortcomings when dealing with such scenarios:

In addition, the utility model has low cost and small footprint.

[0024] See also Figure 1 to Figure 2An embodiment of the utility model provides a dual-channel control barrier, including a barrier housing 1, a movement assembly 2 is arranged in the barrier housing 1, the barrier housing 1 includes a barrier cap 11, a movement mounting plate 12 for fixing the movement assembly 2 is arranged in the barrier housing 1, the movement mounting plate 12 is installed in the barrier to form a partition, the movement assembly 2 is installed on the movement mounting plate 12, and is located between the cavity formed by the movement mounting plate 12 and the barrier cap 11, a controller 3 is arranged in the cavity of the barrier housing 1, the movement assembly 2 includes a motor 24, the A power-loss brake 25 is provided on one side of the input shaft of the motor 24, and a reducer 23 is provided on one side of the output shaft of the motor 24. The reducer 23 is provided with a movement output shaft 21 that penetrates the barrier gate housing 1 on the side away from the motor 24. One end of the movement output shaft 21 is fixedly connected with a key pin at one end of a gate rod clamp, and the other end of the gate rod clamp is nested and connected with one end of the barrier gate rod 5. The barrier gate clamp is used to strengthen the connection and fixation of the output shaft to the barrier gate rod 5 and facilitate disassembly. A second encoder 22 is installed on the housing of the reducer 23, and a first encoder 26 is provided on the end of the power-loss brake 25 away from the motor.

[0025] See also Figure 3 In this embodiment, a first encoder 26 is installed on one side of the input shaft of the motor 24 for recording the absolute position of the shaft of the motor 24, and a second encoder 22 is installed on one side of the output shaft of the reducer 23, wherein the second encoder 22 includes a driving gear 221 coaxially connected to the output shaft of the reducer 23, and a driven gear 222 meshing with the driving gear 221, wherein a magnet 223 is provided inside the driven gear 222 for cooperating with an encoder body 224 axially rotatably connected to the driven gear 222 toward one side of the reducer to record the relative position of the motor shaft.

[0026] The motor 24 is controlled by the controller 3 , the first encoder 26 and the second encoder 22 , so that the position of the gate rod can be precisely controlled.

[0027] Since the utility model is generally installed in an open road environment, there are certain requirements for the maintenance and protection of the equipment. The dual-channel control barrier is provided with a barrier cap 11 on the barrier housing 1, which is used for quick disassembly and access to the movement assembly 2 during maintenance, and a waterproof ring 4 is installed between the movement output shaft 21 and the barrier housing 1, so that the entire device is dustproof and waterproof under the premise of maintenance.

[0028] A gate door 14 is provided on the opposite side of the gate box 1 to the gate pole 5. When the gate door 14 is opened, an electrical installation board 13 installed on the wall can be seen visually. The motor 24 controller, wire duct, switching power supply, air switch, and other power distribution systems are installed on the electrical installation board.

[0029] Working principle: when powered on, the power-off brake 25 loses its braking function. At this time, the motor 24 can rotate forward and reverse under the control of the controller 3. After conversion by the reducer 23, the speed on the output shaft is decelerated and the torque is increased, so that the barrier rod 5 can rotate smoothly. However, after the limiting of the first encoder 26 and the second encoder 22, the barrier rod 5 can rotate 180° smoothly and can be controlled to stay at any position. When the power is suddenly cut off, the power-off brake 25 immediately works to lock the output shaft of the motor to prevent the barrier rod from sliding down. In addition, the power-off brake can also work under the control of the controller when the power is on, so as to strengthen the staying stability of the barrier rod.

[0030] It should be noted that in this embodiment, the motor is a servo motor, the reducer is a harmonic reducer, and the controller is a servo controller. However, this is not limited to the above. The motor can also be replaced by a brushless motor, the reducer can also be replaced by a planetary gear reducer, and so on.

[0031] See also Figures 3 to 5 In one embodiment of the utility model, for some dual-channel scenarios that require temporary unilateral closure or temporary flow restriction or diversion, the barrier rod 5 needs to alternately stop on the left and right sides. In the prior art, for control in different directions, the barrier rod 5 needs to be disassembled and reinstalled, or two barrier devices are installed on both sides, which is costly and inconvenient. However, the utility model utilizes the controllable characteristics of the direction and speed of the motor 24, and at the same time assembles a reducer 23 on the output shaft of the motor 24 to increase the torque, so that the utility model can rotate back and forth smoothly in the left and right directions of 180°. Under the control limit of the first encoder 26 and the second encoder 22, the barrier rod 5 completes the alternate stop on the left and right sides. Due to the small size of the utility model, one can be installed in the middle of some dual-channel roads that require flow restriction to control the diversion of the roads on both sides.

[0032] In summary, the dual-channel control barrier in the above-mentioned embodiment of the utility model mainly utilizes the controllable characteristics of the motor's steering and speed, and cooperates with the reducer to increase the torque while achieving a small size. At the same time, the first encoder and the second encoder limiter are installed on the input shaft of the motor and the output shaft end of the reducer, so that the barrier rod can rotate 180 degrees smoothly and controllably. At the same time, in order to prevent the power-off barrier rod from falling, the input shaft of the motor is equipped with a power-off brake, so that the motor is locked after the power is off, and the power is off and the rod is stopped, which is safe and reliable. In addition, the utility model has low cost and small footprint.
