Abstract
The invention provides a follow-up supporting system which comprises a plurality of follow-up jacks, a hydraulic pump station, an oil pipe and balancing oil cylinders. The follow-up jacks adopt hydraulic drive, and internally adopt mechanical threads to bear upper part loads; and the system presses part of hydraulic oil to the balancing oil cylinder with smaller load from the balancing oil cylinder with larger load through the balancing oil cylinders and hydraulic oil lines till the loads borne by follow-up devices corresponding to the balancing oil cylinders at all points are basically uniform. The follow-up supporting system has the benefits that the follow-up supporting system has reliable bearing force, synchronicity and integral carrying capability, can overcome uniform loads caused by a mechanical machining error of the follow-up jacks, and ensures that the loads of the follow-up jacks in the same group is uniform.
