In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a mine track electric locomotive leaf spring hydraulic pressure replacer, includes operation face, lift post, base and hydraulic system, the one end on the base of the bottom base fixed mounting of lift post, the one end fixed mounting in the upper end of the drive post of lift post of the bottom surface of operation face, hydraulic system intercommunication lift post the feed liquor end with go out the liquid end.
Preferably, the upper end face of the operation face is welded with an upper reinforcing rib, and the upper reinforcing rib extends to the middle of the upper end face of the operation face from one end of the operation face connected with the lifting column.
Preferably, one side or two sides of the lifting column are welded with lower reinforcing ribs, and the lower end faces of the lower reinforcing ribs are welded with the upper end face of the base.
Preferably, the lifting column is a hydraulic automatic lifting column.
Preferably, the lifting column is welded and fixed with the base, and the operation surface is welded and fixed with the lifting column.
Preferably, the hydraulic system consists of a signal control unit and a hydraulic power unit, and the hydraulic system is fixedly arranged on the base.
Compared with the prior art, the beneficial effects of the utility model are that:
this mine track electric locomotive leaf spring hydraulic pressure replacer, can be very convenient insert the operation face to the plate spring lower extreme, the maintainer only needs to fill in the replacer under the electric locomotive plate spring, use hydraulic system to promote the lift post, make the operation face withstand the plate spring lower extreme, demolish old and useless fastening bolt, the fastening bolt of renewal is screwed up, can accomplish the dismouting process, the labor intensity is reduced, the work efficiency is improved, and the face contact is kept with ground to replacer bottom surface in whole process, without the operation of inclining, the security of maintenance operation has been improved.
