Prepressing counter-force frame device of model 0 block support frame

The utility model discloses a prepressing counter-force frame device of a model 0 block support frame, comprising a pillar top pre-planting steel bar, a counter-force frame and a lifting jack, wherein the pillar top pre-planting steel bar is embedded at the top of a pillar body, the counter-force frame is welded by a connecting rod through a ladder-shaped truss, the counter-force frame is connected with the pillar top pre-planting steel bar in an anchoring way, the counter-force frame is arranged right above the support frame, and the lifting jack is arranged between the counter-force frame and the lifting jack. By adopting the structure, the support frame can be prepressed by equivalent load by the stretch-draw counter force by the means that the pillar top pre-planting steel bar is taken as a force application system of the prepressing counter-force frame, so that the prepressing loading problem of the support frame can be well solved.
