Integrated transmission case for electronically operated gate

Abstract

The invention discloses an integrated transmission case for an electronically operated gate. The integrated transmission case adopts two one-way transmissions in opposite directions and rapid opening and slow closing of the electronically operated gate can be realized by a simple structure, so that the integrated transmission case has the advantages of simple structure, low construction cost, low failure rate and low maintaining cost. Meanwhile, the transmission case and a planetary gear reduction gear can be integrally installed in the same transmission case body, so that the problem of single function of a mechanical transmission can be overcome and the whole transmission case can integrally complete mechanical outputs of forward and backward rotation at different speed. At the same time, in the same transmission case body, a torque clutch is arranged between a power system of the electronically operated gate and an opening and closing device of the electronically operated gate so as to increase the torque of a transmission shaft when the electronically operated gate is blocked in the closing motion, and finally, the toque clutch is tripped, the electronically operated gate maintains a harmless clamping force and the motor cannot be blocked from rotating and being burnt down, at the same time, a control motor is controlled reverse rotate to open the gate under the support of a control circuit. The integrated transmission case is a mechanical anti-clamping device having the advantages of simple structure, low construction cost, low failure rate and security and reliability.

Description

technical field [0001] The invention relates to the field of electric doors, in particular to an electric door integrated transmission box. Background technique [0002] Electric doors can realize electric opening and closing, and can cooperate with automatic control devices such as sensors to realize automatic opening and closing, so they are widely used, such as elevator doors, hotel lobby doors, bank lobby doors, and other relatively high-end or high-safety requirements. In places, electric doors generally require fast opening and slow closing to meet the requirements of high door opening efficiency and high door closing safety factor. When the speed of the motor is the same, the output speed and torque are the same. In order to achieve fast opening and slow closing, the speed regulation generally adopts the motor speed control system or the clutch to switch gears with different speed ratios to realize door opening and closing. The above-mentioned system has the disadvan...

[0002] Electric doors can realize electric opening and closing, and can cooperate with automatic control devices such as sensors to realize automatic opening and closing, so they are widely used, such as elevator doors, hotel lobby doors, bank lobby doors, and other relatively high-end or high-safety requirements. In places, electric doors generally require fast opening and slow closing to meet the requirements of high door opening efficiency and high door closing safety factor. When the speed of the motor is the same, the output speed and torque are the same. In order to achieve fast opening and slow closing, the speed regulation generally adopts the motor speed control system or the clutch to switch gears with different speed ratios to realize door opening and closing. The above-mentioned system has the disadvantages of complex structure of the control system, high cost, high failure rate, and high maintenance cost.

At the same time, the function of its mechanical transmission device is single, and it cannot be integrated to meet the requirements of mechanical forward and reverse rotation at different speeds.

At the same time, electric doors are required to have an anti-pinch function to prevent personal and equipment safety accidents. At present, electric doors are generally detected by sensors, and the obstruction signal is transmitted to the electric door electric control device to control the electric door to stop closing and reverse open, so that Avoid accidents, but there are complex system structures, high costs, prone to failures, and certain potential safety hazards
