Dynamometry support model for physical similarity simulation experiment

The utility model discloses a dynamometry support model for a physical similarity simulation experiment. The dynamometry support model comprises a support base, a top beam, a plurality of upright columns, a caving shield, a tail beam, a base lateral sensor, a caving shield lateral sensor, a top beam lateral sensor, a plurality of upright column load sensors and a data acquiring and testing system acquiring and analyzing signals detected by the sensors, height adjusting devices are arranged on the upright columns, the top beam, the caving shield and the tail beam are integrally assembled via a height adjusting mechanism, and the height adjusting devices and the height adjusting mechanism form a height adjusting system for adjusting the supporting height of the top beam. The dynamometry support model for the physical similarity simulation experiment is reasonable in structural design, simple and convenient to use and operate and fine in use effect, the height of a support is adjusted conveniently, a working face roof can be supported, and work resistance of the support can be accurately measured in real time.
