The controller control principle of this application is shown in fig. 6, the sand table can real-time detection system operation situation, starts overload protection and prevents pressing from both sides the protection when necessary in the upset in-process.

And sound absorption materials are adhered in the bearing table body. The sound absorbing material can play the processing of making an uproar that falls of lift in-process, and this application falls the processing back of making an uproar through the vibration isolation, and the partial noise that effectively absorbs motor and transmission system produced at the during operation, the in-process noise that produces of upset is less than 60 decibels, has guaranteed the comfort level of closely operating.

The present application does not intend to connect or secure, and can be implemented by any available prior art. The large sand table electric turnover device is based on stress analysis, based on worm gear transmission and PLC control, comprehensively utilizes theories such as a mechanical theory and a control theory and the like to realize electric turnover of the large sand table, and has the function of realizing turnover of the large sand table within an arbitrary angle range of 0-35 degrees and providing a good human-computer interaction interface, so that the observation visual angle of a commander is ensured. Meanwhile, the sand table turnover mechanism can be driven manually, so that the turnover of the sand table is realized, and the reliability of the turnover mechanism of the sand table is improved.

Has the advantages that: the utility model discloses it lies in to show the advantage: (1) by means of a man-machine design concept, a good man-machine interface is provided, and the visual angles of commanders with different heights are ensured; (2) the system functions can be updated and expanded according to the technical development and requirement change by following the principle of integration and modular design; (3) according to the safety design principle, when the sand table is turned over, the PLC can receive an overload signal to cut off the power supply of the motor in time, so that overload protection is realized, and an anti-pinch protection function is realized; (4) the design principle of reliability is followed, the design of margin is carried out on the thrust of the push-pull system, and the reliable operation of the system is ensured; (5) by adopting the novel sound-absorbing material, partial noise generated by the motor and the transmission system is effectively absorbed.
