Abstract

The utility model discloses a kind of device for being used to dismantle hydro-turbo generator set water guide leaf Lower shaft sleeve, described device is made up of crossbeam, two hydraulic jacks, pull bar, terminal pad and multiple pins；Advantageous effects of the present utility model are：A kind of device for being used to dismantle hydro-turbo generator set water guide leaf Lower shaft sleeve is proposed, after the device, very easily Lower shaft sleeve can be split out out of mounting hole, mounting hole will not be caused to damage, operating efficiency is higher.

Description

For dismantling the device of hydro-turbo generator set water guide leaf Lower shaft sleeve

Technical field

A kind of Overhauling for Hydraulic Generator Set technology is the utility model is related to, more particularly to it is a kind of for dismantling hydrogenerator The device of group guide vane Lower shaft sleeve.

Background technology

Lower shaft sleeve is the strength member in turbine-generator units, and its effect is that axle journal under guide vane is lubricated, and makes to lead Waterleaf can be rotated swimmingly, in use, Lower shaft sleeve is typically embedded in the mounting hole below guide vane on pedestal, Lower shaft sleeve category In consumable accessory, it is necessary to regularly replace.

A kind of typical structure of Lower shaft sleeve is (to be generally copper or copper alloy in the metal of cylindrical shape, have certain wall It is thick) multiple through holes are set in the side wall of matrix, inlaid solid lubrication material in through hole, the side wall of the Lower shaft sleeve of this structure is relative Thicker, after long-term use, Lower shaft sleeve is combined very close with mounting hole, when changing, it is difficult to by Lower shaft sleeve from peace Filling in hole and take out, be typically only capable to destroy Lower shaft sleeve using violence dismounting mode, then further take out, operation is not only wasted time and energy, But also mounting hole is easily damaged, cause subsequently to also need to repair mounting hole, influence operating efficiency.

Utility model content

The problem of in background technology, it is used to dismantle under hydro-turbo generator set water guide leaf the utility model proposes one kind The device of axle sleeve, the Lower shaft sleeve are tubular structure body, and multiple through holes are provided with the side wall of Lower shaft sleeve；In multiple through holes, edge Lower shaft sleeve axial direction, the multiple through holes of position identical are designated as a sets of vias；Before dismounting, the Lower shaft sleeve is socketed in the peace on pedestal Fill in hole, the axial direction of Lower shaft sleeve is vertical with pedestal upper surface；Its improvement is：Described device by crossbeam, two hydraulic jacks, Pull bar, terminal pad and multiple pins composition；The hydraulic jack is placed on pedestal upper surface, the push rod court of hydraulic jack On, two hydraulic jacks are located at mounting hole both sides respectively, and the crossbeam is placed on the push rod upper surface of two hydraulic jacks On；The terminal pad is disc-shaped structure body；The upper end of the pull bar in the middle part of crossbeam with being connected, pull bar axial direction and pedestal upper surface Vertically, the lower end of pull bar and terminal pad are coaxially connected, and the diameter of terminal pad is less than Lower shaft sleeve internal diameter, and terminal pad is located at Lower shaft sleeve Interior, at least there is a sets of vias in the top of terminal pad, the sets of vias above terminal pad is designated as connecting hole group, the multiple Pin is socketed in the administrative multiple through holes of any connecting hole group correspondingly, when the outer end of pin and the outer peripheral face of Lower shaft sleeve When flushing, projection of the pin the inner on Lower shaft sleeve axial direction is on the upper surface of terminal pad.

When being dismantled using device of the present utility model to Lower shaft sleeve, first solid remaining on Lower shaft sleeve is moistened with instrument Sliding material prizes out of through hole, so as to obtain described connecting hole group, is then first installed in place two hydraulic jacks, then Crossbeam, pull bar and terminal pad are installed in place again, are then again installed in place multiple pins, then starts hydraulic jack by horizontal stroke Beam is jacked up upwards, and terminal pad is lifted up by crossbeam by pull bar, and terminal pad is further through multiple pins by stress to lower axle Put, when hydraulic jack jacks up crossbeam, Lower shaft sleeve is also pulled out out of mounting hole therewith, in this way to Lower shaft sleeve Dismantled, easy to operate, the used time is shorter, and mounting hole is hardly caused to damage, and is greatly improved upkeep operation effect Rate, meanwhile, the Lower shaft sleeve split out is also more intact, can also be continuing with after returning factory and office's reason, can effectively save cost.

Advantageous effects of the present utility model are：Propose a kind of for dismantling hydro-turbo generator set water guide leaf Lower shaft sleeve Device, after the device, very easily Lower shaft sleeve can be split out out of mounting hole, mounting hole will not be caused to damage Wound, operating efficiency are higher.
