Barrier gate machine core device with efficient transmission and high adjustability

Abstract

The invention relates to a barrier gate machine core device with efficient transmission and high adjustability. The barrier gate machine core device comprises a motor crank, a guiding rod and a transmission main shaft; and the first end of the motor crank is fixedly connected with an output shaft of a speed reducing motor, the second end of the motor crank is hinged to the guiding rod, the transmission main shaft comprises a first shaft part and a second shaft part, a sliding block supporting seat is arranged between the first shaft part and the second shaft part, the guiding rod is slidably connected with the sliding block supporting seat, the motor crank rotates and drives the guiding rod to swing, the guiding rod drives the sliding block supporting seat to push the transmission main shaft to swing between the first limit position and the second limit position, and a gate rod is connected with the transmission main shaft to realize swing between the horizontal direction and the vertical direction. According to the barrier gate machine core device, the force transferring efficiency of a barrier gate machine core and the stability of a rack can be improved, the motion gap is small,the life of a speed reducer is obviously prolonged, the cost is low, thus the production cost of a barrier gate is finally lowered, the using stability of a barrier gate machine is improved, and thelife of the barrier gate machine is prolonged.

Description

technical field [0001] The invention relates to a parking lot and a road barrier, in particular to a barrier gate movement device with high transmission efficiency and high adjustability. Background technique [0002] At present, in the barrier gate industry, the transmission device of the gate movement is generally in the form of a four-bar linkage mechanism or a direct drive of a motor. The disadvantages of the existing four-bar mechanism in the barrier gate industry are mainly due to the fact that the swing angle of the rocker is 90 degrees during work, and the transmission angle between the connecting rod and the rocker changes greatly, which makes the transmission efficiency of the mechanism low and causes a large impact on the frame. The impact of the brake lever will cause greater vibration and affect the life of the motor; the direct drive of the motor generally uses a servo or frequency converter to control the speed of the motor, and the cost is relatively high. ...
