The action principle of the mechanism is as follows: in most cases, the operation platform needs to advance along the length direction to construct a row of suspended ceilings of buildings, at the moment, the jack is retracted, the large roller contacts the ground, a worker stands on the top of the platform, and the first motor is remotely controlled to drive the large roller to move longitudinally; after one row of construction of furred ceiling is accomplished, when needing operation platform lateral shifting to next row of construction, the drive jack for the small idler wheel sinks to touch to earth, and with a little distance of big gyro wheel lifting, makes big gyro wheel and ground break away from, drives the second motor this moment, drives the small idler wheel, realizes lateral shifting. And when the operation platform transversely and longitudinally moves in place, the jack is driven, so that the large roller and the small roller contact the ground simultaneously, and the large roller and the small roller which are vertical to each other are locked mutually, thereby avoiding the accidental movement of the operation platform.

By the aid of the device, the operation platform does not need a worker to climb down from the top of the operation platform, and does not need another worker to push the platform, and the operation platform only needs one worker to stand at the top of the support for remote control operation, so that the platform can automatically move transversely or longitudinally. Therefore, labor cost and labor cost are saved, and the use is convenient and quick. Moreover, when the jack jacks down, the four small rollers are uniformly distributed at four corners of the bottom of the operating platform, so that the balance is good; the distance for lifting the large roller by the small roller is not large, and only the large roller is lifted off the ground, so that the safety and the stability of the whole platform are not problematic, and the potential safety hazard of instability is avoided; moreover, two motors and a jack are additionally arranged on the bottom plate, so that the counterweight at the bottom of the operating platform is further increased, the stability of the operating platform is further enhanced, and the potential overturning hazard is further avoided. More expensively, new braking components are not additionally arranged on all the rollers, more complex disc brakes, hoops and the like are not needed, two groups of rollers which are perpendicular to each other are used for self-locking, the two groups of rollers realize three functions of transverse moving, longitudinal moving and self-locking, all improvement points are combined and mutually promoted, and the technical effect that one is added and one is larger than two is realized.

Preferably, the bottom surface of the bottom plate is provided with a first travel switch, the bottom surface of the bottom plate is also provided with an L-shaped frame, the L-shaped frame is provided with a second travel switch, and the lifting disc is not in contact with the two travel switches when the large idler wheel and the small idler wheel are in contact with the ground; the first travel switch is electrically connected with the first motor, and the second travel switch is electrically connected with the second motor.

The principle of the design is that when the two groups of rollers are in a state of being in contact with the ground, the lifting disc is not in contact with the two travel switches, so that circuits of the two groups of motors are both broken, and the situation that the rollers are forced to move to cause short circuit of the motors in a self-locking state is prevented; only when the lifting disc rises for a distance of 5mm, namely the small roller is completely separated from the ground, and the large roller is fully attached to the ground, the first travel switch is pressed, so that the circuit path where the first motor is located is formed, and the large roller can rotate; or, when the lifting disc descends by a distance of 5mm, namely the small roller is fully contacted with the ground and the large roller is completely separated from the ground, the lifting disc can press the second travel switch, so that the small roller can rotate when the circuit path where the second motor is located is closed. In other words, the device realizes the following functions that two groups of rollers cannot rotate accidentally during the ascending or descending process of the lifting disc, and the rollers are allowed to move only after one group of rollers is fully attached to stabilize the whole operating platform, so that the phenomenon that the operating platform collapses due to the fact that a certain group of rollers accidentally moves during the ascending or descending process of the lifting disc is avoided.
