Correspondingly, present invention also offers a kind of method of railcar u-turn, u-turn is turned round using jacking described above
Device come realize railcar reverse end for end, the described method comprises the following steps:
S1, adjustment railcar center and the center superposition of jacking revolution upender, rotating arm 9 make the stacker of support arm
95 positioned at the underface of the jack-up point of railcar;
S2, continuously pressurizeed up and down to manual pump 15, the top of jack 4 is first contacted with the lower surface of slew gear, enter
And eject slew gear upwards, until the stacker 95 of slew gear contacts with the jack-up point of railcar and by track roof
Rise, railcar wheel rim is higher by rail level;
S3, the gyroaxis of slew gear rotate 180 ° relative to rotary table, make support arm 9 drive railcar to rotate 180 °,
Realize that railcar is reversed end for end;
S4, the manual pump 15 of release pressure, jack 4 drive slew gear to decline, until jacking revolution upender with
Railcar does not contact, and after railcar is rolled away from, packs up jacking revolution upender.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
