Flapping door unit transmission mechanism and flapping door unit

Abstract

The invention provides a flapping door unit transmission mechanism and a flapping door unit, belongs to the field of access control, automatic ticket checking equipment and rail transit equipment. Theflapping door unit transmission mechanism is used in the flapping door unit, the flapping door unit includes a motor and a flapping door rotating shaft, and the transmission mechanism includes a drive synchronous pulley, a synchronous belt and a driven synchronous pulley. The drive synchronous pulley, the driven synchronous pulley and the synchronous belt are horizontally disposed. The axis of the drive synchronous pulley and the axis of the driven synchronous pulley are both perpendicular to the horizontal plane. The drive synchronous pulley and the driven synchronous pulley perform synchronous transmission through the synchronous belt, and the torque of a main shaft of the motor is transmitted to the flapping door rotating shaft. By using the flapping door unit transmission mechanism and the flapping door unit, the precision of the movement and braking of a flapping door is improved, the installation space is greatly saved, the cost of a gate machine is reduced, and the maintenancetime and labor cost are saved.

Description

technical field [0001] The invention belongs to the fields of access control, automatic ticket checking equipment and rail transit equipment, and in particular relates to a flapping door unit transmission mechanism and a flapping door unit. Background technique [0002] At present, the flapping door unit is widely used in the fields of access control, automatic ticket checking equipment, and rail transit equipment. The flapping door unit is an AFC special module integrating optical, mechanical and electrical technologies. It is installed in the gate as a blocking mechanism to effectively control the entry and exit behavior of pedestrians and passengers. Only those with legal authorization are allowed to pass. Provide fast ticket check-in and entry-exit services for passengers. [0003] The flapping door has a flapping door leaf that can be opened and closed under the control of the motor device, which can fully open and block the gate passage, and can also be completely clo...

AI Technical Summary

Problems solved by technology

[0006] 1. Restricted by the overall height of the gate or automatic ticket gate (equipment height has relevant industry regulations), when the flapping gate unit is assembled into the gate or automatic ticket gate, due to limited space, it cannot ensure that it is installed perpendicular to the gate The base surface is horizontal, causing the flapping door leaf to tilt and rotate, which affects the overall appearance of the equipment

[0007] 2. Limited by the overall height of the gate or automatic ticket gate, it is impossible to adopt a direct connection scheme that controls the drive shaft of the motor and the shaft of the flapping door to keep vertical

[0008] 3. Limited by the height of the inner space of the gate or automatic ticket gate, it is impossible to adopt the solution of co-existence of electromagnetic brake and motor. Therefore, in the flapping gate units currently used in the industry, there are often only motors without electromagnetic brakes

After the lack of electromagnetic brake, the brake of the gate can only be braked and locked by the reverse and locked rotor of the motor itself, which greatly reduces the movement accuracy and braking accuracy of the flapping door

[0009] 4. When the motor and the electromagnetic brake fail, the door unit must be disassembled as a whole before the electromagnetic brake and the motor can be disassembled and repaired if the scheme of direct connection with the drive shaft of the flapping door is adopted, which wastes manpower and time and leads to a high cost of the direct connection scheme. maintenance cost
