The controller 8 can be independently arranged outside the power push rod 3, and can control the power push rod 3 to move through electric connection, and can also be integrated inside the power push rod 3 so as to save the space of the device. The controller 8 may receive the suspended monorail switch control signal through a wired mode, or may receive the suspended monorail switch control signal through a wireless communication mode such as WIFI, bluetooth, 4G, 5G signals and the like through an integrated communication module. The controller 8 can also determine whether the power pushrod 6 is pushed out or retracted into place by acquiring the movement time of the power pushrod 3, acquiring the thrust value of the power pushrod 3, and the like. When the controller 8 receives the switching signal of the movable rail 1, the power push rod 3 is synchronously controlled to move, so that the two compensation rails 2 are locked.

When the embodiment of the invention works, the suspension type monorail switch signals received by the controller 8 control the power push rod 3 to do linear reciprocating motion, the power push rod 3 does linear reciprocating motion to drive the lifting crank shafts 401 of the lifting crank assemblies 4 to rotate, and the first crank arms 404 and the second crank arms 405 arranged on the lifting crank shafts 401 respectively drive the locking crank shafts 501 in the two locking crank assemblies 5 positioned at the two ends of the power push rod 3 to synchronously rotate through pull rods, and the two rotating locking crank shafts 501 respectively drive the locking shafts 602 in the corresponding locking assemblies 6 to ascend or descend through the pull rods. As shown in fig. 4, when the two sets of locking shafts 602 descend to the lowest point, the locking device of the suspended monorail switch compensating rail 2 locks both ends of the two compensating rails 2, and at this time, both ends of the two compensating rails 2 are in a locking state and cannot be turned over. As shown in fig. 5, when the two sets of locking shafts 602 rise to the highest point, the suspended monorail switch compensating rail 2 locking device unlocks the two compensating rails 2, at which point the compensating rails 2 can be flipped. Because the two ends of the two compensation rails 2 are synchronously locked when the compensation rails 2 are locked, the locking strength is improved, the locking reliability is enhanced, and the safety of the device is further improved.
