Mobile framework moving trolley
The invention relates to a mobile framework moving trolley. The mobile framework moving trolley is characterized by comprising a trolley beam saddle, a main jack, n guide bars and joists. The main jack is vertically arranged at the center position of the trolley beam saddle, the n uniformly-distributed guide bars are slidingly arranged on the trolley beam saddle by taking the main jack as the center, n is greater than 2, the bottoms of the joists are connected with the head end of a piston rod of the main jack and the ends of the guide bars, sliding beams are installed on the two sides of the bottom of a girder, the bottoms of the two sliding beams are installed on the joists in a horizontally sliding manner, the girder is driven by a longitudinal moving drive device to move longitudinally relative to the joists and a locking mechanism is arranged on the guide bars. As the support structure of the single main jack and the guide bars is adopted, the joists fulfill the function of balancing stress, the height of the guide bars can be freely adjusted according to the stroke of the main jack, and the guide bars are self-locked through the locking mechanism, so that the safety reliability and the lifting stability are improved, the weight is decreased, and the cost of the hydraulic system is lowered compared with a double-jack system as the single main jack is used.
