Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.

As shown in Figure 3, a swivel nut 13 on cover in the middle part of preset hydro-cylinder type four column press column 7, and guiding swivel nut 13 by feather key 12, swivel nut 13 is threaded with adjusting nut 11, and makes adjusting nut 11 and swivel nut 13 catch up with crossbeam 1 by trim ring 14 to keep synchronously promoting up and down.When overhead oil cylinder 9 lifts entablature 1 to certain altitude, by nut driving mechanism rotating adjusting nut 11, swivel nut 13 is slided up and down along column face under the guiding of guide pillar key 12, when suitable distance is adjusted in swivel nut 13 bottom surface and entablature 1 bottom surface, stop adjusting nut 11, by overhead oil cylinder 9 hydraulic action decline entablature 1, until column face is withstood in swivel nut 13 bottom surface, and hydraulic pressure pins, height of packing compact adjustment terminates.
