Examples

In the scheme, in the working process of the vertical lift gate, a motor 5 is electrified to rotate to drive a speed reducer 4, and the speed reducer 4 converts high-speed rotation output by the motor 5 into a slow and uniform rotation speed and transmits the slow and uniform rotation speed to a transmission rod 7; the transmission rod 7 rotates to drive the upper chain wheel 8 to rotate, so that the two chains 12 rotate; the two chains 12 apply tension to the flashboard 1 at the same time, the tension of each chain is uniform and the same, the tension to be applied to the gate 1 is the sum of the tension of the two chains 12, the gate 1 is under the combined action of the two chains 12, and finally the flashboard 1 is driven to ascend or descend;
