Tunnel construction supporting frame

The tunnel construction supporting frame comprises a supporting table, telescopic rods and universal wheels, a first motor and a second motor are arranged in the center of the interior of the supporting table, one end of the first motor is rotationally connected with a first threaded rod, and one end of the second motor is rotationally connected with a second threaded rod. In actual use process, the first motor and the second motor can be controlled through the controller; therefore, when the No.1 motor and the No.2 butyl amido are started at the same time; the first threaded rod and the second threaded rod are forced to rotate; therefore, the two limiting sliding blocks can transversely move on the supporting tables of the limiting sliding blocks through threaded connection with the threaded rods. When the two limiting sliding blocks move inwards at the same time, the first crawling ladder and the second crawling ladder can tilt upwards, and therefore the first rotating mechanism, thesecond rotating mechanis
