Photo-thermal heliostat pitching position precision driving push-pull rod type structure

A photo-thermal heliostat pitching position precision driving push-pull rod type structure comprises a ball screw, a pitching transmission support and an orientation speed reducer, the orientation speed reducer is fixed to a heliostat stand column barrel, the output end face of an orientation speed reducer output disc faces upwards and is connected with the pitching transmission support, and a lead screw nut base supporting frame is fixed to one side face of the pitching transmission support. An articulated shaft is arranged at the end head of the lead screw nut base supporting frame. The topof the pitching transmission support supports a transmission main shaft through a sliding bearing, the middle of the transmission main shaft is fixedly sleeved with a swing connecting rod arm, a leadscrew sleeve is hinged to the end, away from the transmission main shaft, of the swing connecting rod arm, and a ball screw is rotatably connected into the lead screw sleeve. The lead screw nut is connected to the lead screw n
