The invention discloses a control method for a searching erecting mechanism, relates to a method for achieving erection and storage of the searching erecting mechanism through control over a hydraulic system, and aims at providing the control method for the searching erecting mechanism, wherein by means of the control method, mechanical disturbance can be overcome, and whether a bolt is arranged in place or not can be judged. The method comprises the following steps that at the initial erecting stage, an electromagnetic reversing valve YA1+ and a hydraulic flow speed regulating valve are opened; at the erecting tail end, the hydraulic flow speed regulating valve is turned down till the hydraulic flow speed regulating valve is closed; at the initial storage stage, an electromagnetic reversing valve YA1- and the hydraulic flow speed regulating valve are opened; at the storage tail end, the hydraulic flow speed regulating valve is turned down till the hydraulic flow speed regulating valve is closed; if the bolt does not stretch in place, an electromagnetic reversing valve YA2+ and the hydraulic flow speed regulating valve are opened, and the hydraulic flow speed regulating valve is closed till the signals exist in a bolt stretching-in-place sensor; and if the bolt does not retract in place, an electromagnetic reversing valve YA2- and the hydraulic flow speed regulating valve are opened, and the hydraulic flow speed regulating valve is closed till signals exist in a bolt retracting-in-place sensor.
