The invention discloses a robot elevator pedaling mechanism, and belongs to the field of hydraulic elevators. The robot elevator pedaling mechanism is characterized in that two main oil cylinder rodsstretch and retract alternately to drive an elevator car to ascend or descend, the main oil cylinder rods are connected with auxiliary oil cylinder rods, an auxiliary oil cylinder is connected with amachine box, an electromagnet coil in the machine box is electrified, and an electromagnet bolt is inserted into a tooth groove of a rack guide rail; due to the fact that two oil ports of the auxiliary oil cylinder are connected with two oil ports of a three-position four-way reversing valve, when the main oil cylinder rods stretch out and draw back, the auxiliary oil cylinder rods (with valve element enginery of Y type) are driven to be stretched out and drawn back, upper pressure oil and lower pressure oil of an auxiliary oil cylinder piston can flow mutually, and surplus oil flows out through a safety overflow valve, and oil is sucked in through a one-way valve is the oil is short, so that operation of the main oil cylinder rods is not affected; and at the moment, one side of the three-position four-way reversing valve is electrified, and the two main oil cylinder rods are alternately reversed while the auxiliary oil cylinder rods and the other main oil cylinder rod extend or retract, so that a main oil cylinder stably drives the elevator car to move up and down without bumping.

    机器人电梯蹬踏机构:属液压电梯领域。两个主油缸杆交替伸缩带动电梯轿厢升或降。主油缸杆连接副油缸杆,副油缸连接机箱、机箱中的电磁铁线圈通电、电磁铁插销插入齿条导轨的齿槽中。因副油缸两油口连接三位四通换向阀的两油口,(阀芯机能Y型)当主油缸杆伸缩时带动副油缸杆伸缩,副油缸活塞上下压力油可互相流动,多余油通过安全溢流阀流出,不足通过单向阀吸进。因此不影响主油缸杆的运行,此时三位四通换向阀一边通电,副油缸杆与另一主油缸杆伸或缩的同时两个主油缸杆交替换向,使主油缸平稳带动轿厢上或下运行,没有颠簸。
