Abstract
The utility model discloses a nut dismantling device for a boiler water pump impeller, which comprises a hexagonal sleeve, a crowbar and a sleeve, wherein the sleeve is fixedly arranged on the outer ring of the hexagonal sleeve and provided with a through-hole matched with the hexagonal sleeve, and the crowbar penetrates the sleeve and the through-hole in the hexagonal sleeve and is in welded connection with the sleeve and the hexagonal sleeve. The nut dismantling device for the boiler water pump impeller has the advantages that a nut of the boiler water pump impeller can be dismantled conveniently and rapidly, and the knock resiliency and cutting with a cutter are avoided, the nut dismantling work efficiency is effectively improved, and the maintenance quality of the boiler water pump is ensured.
Description
Technical field
The utility model relates to the dismantling device that a kind of stove water pump vane is pieced together cap.
Background technique
The stove water pump is used for the boiler equipment of generator set, and the stove water pump vane is located on the stove water pump main shaft by piecing together cap, pieces together cap and spindle end by being threaded; In the troubleshooting of stove water pump or when examining surely, because the influence of production scene operating mode, the stove water pump vane often occurs and piece together the phenomenon that cap and spindle thread are killed.And dismounting adopt usually when piecing together cap in Hexagonal jacket be inserted in and piece together on the cap, will piece together the cap dismounting by the rotation crow bar in the through hole of Hexagonal jacket in then crow bar being penetrated; But run into when piecing together cap and killing, manpower can't rotate crow bar, and piecing together cap can't split out, this moment, the general hammer that adopts knocked crow bar, and is because crow bar penetrates interior Hexagonal jacket through hole, flexible when knocking, decomposed percussion power, exerted all one's strength all to affact and piece together on the cap, thereby can't dismantle the assembly cap of killing; Still can't dismantle when piecing together cap knocking crow bar, the method that can only adopt hand-held cutting machine cutting to piece together cap, obviously cap is pieced together in cutting very big uncertain factor and risk, very easily damages stove water pump vane and spindle nose screw thread, and the effort of taking a lot of work, influenced the repair quality and the efficient of stove water pump.
Summary of the invention
Technical problem to be solved in the utility model provides the dismantling device that a kind of stove water pump vane is pieced together cap, utilize this dismantling device to piece together cap by convenient and swift dismounting stove water pump vane, avoid knocking elasticity and adopt the cutting machine cutting, effectively improved the dismounting work efficiency of piecing together cap, the repair quality of the stove water pump of guaranteeing to know clearly.
For solving the problems of the technologies described above, the dismantling device that the utility model stove water pump vane is pieced together cap comprises interior Hexagonal jacket, crow bar and sleeve, described sleeve is fixed at described interior Hexagonal jacket outer ring and has the through hole that mates with interior Hexagonal jacket, and described crow bar penetrates the through hole of described sleeve and interior Hexagonal jacket and is welded to connect.
Above-mentioned crow bar can adopt solid crow bar.
Because piecing together the dismantling device of cap, the utility model stove water pump vane adopted technique scheme, be that this dismantling device comprises interior Hexagonal jacket, crow bar and sleeve, described sleeve is fixed at described interior Hexagonal jacket outer ring and has the through hole that mates with interior Hexagonal jacket, and described crow bar penetrates the through hole of described sleeve and interior Hexagonal jacket and is welded to connect.This dismantling device can be convenient and swift dismounting stove water pump vane piece together cap, avoid knocking elasticity and adopt the cutting machine cutting, effectively improved the dismounting work efficiency of piecing together cap, the repair quality of the stove water pump that guarantees to know clearly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation that the utility model stove water pump vane is pieced together the cap dismantling device.
Embodiment
As shown in Figure 1, the dismantling device that the utility model stove water pump vane is pieced together cap comprises interior Hexagonal jacket 1, crow bar 3 and sleeve 2, described sleeve 2 is fixed at described interior Hexagonal jacket 1 outer ring and has the through hole 21 that mates with interior Hexagonal jacket 1, and described crow bar 3 penetrates the through hole 21 of described sleeve and interior Hexagonal jacket and is welded to connect.
Above-mentioned crow bar 3 can adopt solid crow bar.
In this dismantling device, sleeve is fixedly set in interior Hexagonal jacket outer ring, and the intensity of having reinforced interior Hexagonal jacket has been thickeied the wall thickness of interior Hexagonal jacket, and Hexagonal jacket is more firm in making, and welding made it to fuse after crow bar penetrated the through hole of sleeve and interior Hexagonal jacket; When piecing together the cap dismounting, only need rotate crow bar, or meet when piecing together cap and killing, adopt hammer to touch crow bar crow bar is rotated, thereby cap is pieced together in dismounting; When hammer touches crow bar, because crow bar and sleeve and interior Hexagonal jacket are integrally welded, elasticity when having avoided knocking, percussion power is concentrated on the crow bar, this percussion power all acts on sleeve and the interior Hexagonal jacket, make piecing together cap can be for convenience detach, has avoided the damage of impeller and spindle nose screw thread in the disassembly process, improve the dismounting efficient of piecing together cap, guaranteed the quality of stove water pump maintenance.Adopt solid crow bar to make to knock to be easier to stressedly, further overcome the elastic force of knocking, make the damage that percussion power is more concentrated and avoid crow bar to be knocked.
Claims (2)
1. a stove water pump vane is pieced together the dismantling device of cap, Hexagonal jacket and crow bar in comprising, it is characterized in that: also comprise sleeve, described sleeve is fixed at described interior Hexagonal jacket outer ring and has the through hole that mates with interior Hexagonal jacket, and described crow bar penetrates the through hole of described sleeve and interior Hexagonal jacket and is welded to connect.
