As specializing, described lifting support comprises base plate and two back plates, and the lower end of two back plates is arranged on base plate, and described through hole is arranged on base plate, and two back plates form described storage tank.The lifting support of this structure is simple in structure, easy to manufacture, and cost is low.
As improvement, between back plate and base plate, be provided with reinforcement gusset, to improve the bearing strength of lifting support.
As improvement, between two back plates, be connected with connecting panel, further to improve the intensity of lifting support.
As improvement, in the upper end of back plate, be provided with and dodge breach.Because back axle is circular arc, breach is arranged to dodge in the upper end of board, can avoid the interference of back axle, therefore, more failure-free is realized lifting.
As improvement, also comprise travel(l)ing rest.When the stroke of jack has in limited time, can be by the lifting that a plurality of travel(l)ing rests are realized step be set under jack.
As improvement, in one end of lifting bearing pin, be provided with screw hole, on screw hole, be inserted with and keep out screw, for preventing that lifting bearing pin from departing from pin shaft hole, to improve the reliability of lifting.
