When the unit needs overhaul, can directly dismantle the wear-resisting board that wears badly, change spare part wear-resisting board and go, shortened the change time of wear-resisting board, reduced the cost of overhaul.
Drawings
Fig. 1 is a schematic view of the assembly structure of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
In the figure: cutting polishing assembly 1, slide bar support 2, screw headless 3, screw 4, wear plate 5, installation body 6, slide bar stand 7, slide bar 8, holding rod 9, spacing bolt 10, lifter 11, cutter 12, abrasive disc 13.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): as shown in figure 1 and figure 2, a wear-resistant plate structure can be dismantled to hydraulic turbine top cap, end ring, including installation body 6, 6 terminal surfaces of installation body are equipped with wear-resistant plate 5, are equipped with 2 screws 4 that extend to in the installation body 6 in the wear-resistant plate 5, are equipped with on the screw 4 and are the screw headlining 3 of integration with screw 4, are equipped with slide bar support 2 on the wear-resistant plate 5, slide bar support 2 includes a pair of slide bar stand 7, is equipped with the slide bar 8 that cup joints with holding rod 9 is movable between two slide bar stands 7. The slide bar bracket 2 is provided with a cutting and polishing component 1 movably contacted with the upper end surface of the screw 4.
The cutting and polishing assembly 1 comprises a holding rod 9, a lifting rod 11 movably connected with the holding rod 9 in a limiting and sleeved mode is arranged at the lower end of the holding rod 9, and a limiting bolt 10 inserted into the lifting rod 11 is arranged on the holding rod 9. The lower end of the lifting rod 11 is provided with a cutter 12 which is integrated with the lifting rod 11.
