Description
Technical field
The utility model relates to axle sleeve extractor, is specifically related to centrifugal pump of single stage type axle sleeve extractor.
Background technology
Centrifugal pump of single stage type, as a kind of common mechanical equipment, is widely used in each elephant, industrial and mining enterprises.For ensureing the safety and steady Effec-tive Function of centrifugal pump, maintenance process simulation be carried out, relating to the replacing of related accessory, often will dismantle in Renewal process or change axle sleeve.In the process of dismounting axle sleeve, owing to being subject to centrifugal pump body structure influence, make drawbench pulling claw be subject to space constraint, axle sleeve inner side end cannot be put into, therefore cannot use, hand hammer can only be used to knock flat chisel, pick out axle sleeve with flat chisel, due to not easy to operate in process, there is the situation that instrument skids, dynamics is excessive, cause axle sleeve and pump shaft to produce unexpected damage, reduce the service life of axle sleeve and pump shaft.
Summary of the invention
For solving the problems of the technologies described above, the utility model adopts clamping pin structure to substitute drawbench pulling claw, does not limit when pulling by pump body structure, and bayonet lock to pull axle sleeve non-slip, do not damage axle sleeve and pump shaft.
The technical scheme that the utility model adopts is: a kind of centrifugal pump of single stage type axle sleeve extractor, comprise sleeve, jackscrew, bayonet lock, handle, described sleeve is cylindrical, hollow steel cylinder, sleeve diameter is greater than axle sleeve external diameter, the steel plate shutoff that sleeve one end is circular, the other end is uncovered, described steel plate is arranged the first tapped through hole, jackscrew is combined with in first tapped through hole, the barrel of sleeve opening end is symmetrical arranged square draw-in groove, in draw-in groove, bayonet lock is installed, described sleeve wall is arranged the second tapped through hole, in the second tapped through hole, handle is installed.
Preferably, described first tapped through hole is arranged on steel plate circle centre position.
Preferably, described square draw-in groove is four, and circumferentially same, every two sides being symmetricly set on circumference, described bayonet lock is two, and every root bayonet lock is through symmetrically arranged two draw-in grooves.
Preferably, described bayonet lock is square key pin.
Preferably, described jackscrew one end is cone, and the other end is the screw thread steel pole with hexagonal (hexagon)nut.
Preferably, described handle is the cylindrical metal bar of TOE.
The beneficial effects of the utility model are: the utility model in use, uses bayonet lock to block axle sleeve, non-slip when pulling axle sleeve, reliability is high, and bayonet lock only blocks end face of shaft bush, injury is not produced to boss surfaces and pump shaft surface, avoids the damage of axle sleeve and pump shaft.This apparatus structure is simple, is easy to assembling and operation.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the sectional view at the utility model AA place.
In figure: 1, sleeve, 2, jackscrew, 3, bayonet lock, 4, handle, the 5, first tapped through hole, the 6, second tapped through hole, 7, draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1 and Figure 2, a kind of centrifugal pump of single stage type axle sleeve extractor, comprise sleeve 1, jackscrew 2, bayonet lock 3, handle 4, sleeve 1 is cylindrical, hollow steel cylinder, sleeve 1 internal diameter is greater than axle sleeve external diameter, the steel plate shutoff that sleeve 1 one end is circular, the other end is uncovered, and steel plate circle centre position arranges the first tapped through hole 5, jackscrew 2 is threaded connection, screw in the first tapped through hole 5, jackscrew 2 one end is cone, and the other end is the screw thread steel pole with hexagonal (hexagon)nut.Symmetrical between two on the barrel of sleeve 1 opening end four square draw-in grooves 7 are set altogether, bayonet lock 3 is square key pin, totally two, every root bayonet lock 3 passes perpendicularly through in two symmetrical draw-in grooves 7, sleeve 1 wall is arranged the second tapped through hole 6, the cylindrical metal bar handle 4 of TOE is threaded connection, and is screwed in the second tapped through hole 6 on sleeve 1 wall.
During work, entangle axle sleeve with sleeve 1 and arrive below axle sleeve inner face, two bayonet locks 3 are inserted in the draw-in groove 7 of sleeve 1, block axle sleeve inner face, jackscrew 2 withstands pump axle end center hole and screws, and handle 4 is tightened, and prevents the stressed rotation of sleeve 1, being headed into by jackscrew 2 makes bayonet lock 3 produce pulling force, is taken off by axle sleeve from pump shaft.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
