[0016] (III) Beneficial effects
[0017] Compared with the prior art, the present invention provides an intelligent elevator for automation system integration, which has the following beneficial effects:
[0018] 1. By setting up weightlessness sensors, electric push rods, movable plates and anti-fall teeth, the weightlessness force of falling is monitored in real time through the weightlessness sensors, and the monitoring data is integrated and interconnected with the automation system.

[0019] 2. By setting a rotating arm, roller, pre-tightening adjustment bolt, pressure plate and spring, during the process of the elevator rising and falling, the roller is used to roll in contact with the elevator body to achieve an auxiliary guiding effect on the lifting and lowering of the elevator body. Due to the difference in elevator models, the required auxiliary pressure is different. By rotating the pre-tightening adjustment bolt, the position of the pressure plate can be adjusted by rotating the pre-tightening adjustment bolt and the rotating arm thread, thereby changing the degree of spring compression and transmitting the reaction force from the rotating arm to the roller to ensure the stable operation of the elevator body.
