Description
Technical field
The utility model relates to a kind of improvement of underground coal mine development machine coal cutting portion motor pulley extractor.
Background technique
Used a kind of important tool when pulley extractor is underground coal mine replacement motor wheel, common structure be by pusher dog,
The structure member that one kind of composition can extract outward motor wheel is bolted with bar is suppressed in hydraulic jack, but tradition pulls out wheel
When development machine coal cutting portion motor spline housing is extracted in underground, since the outer wall of spline housing is too narrow, pusher dog is not easy to put forth effort device, so
So that it is difficult to pull out wheel operation irregularity, and it is very time-consuming laborious, great inconvenience is brought to the normal production work in underground.And it is pulling out
In the process, once encountering wheel connects excessively tight situation with motor, it often will easily take turns or motor shaft damages, in addition, installing
When it is also relatively difficult, generally require minimum two people and cooperate and could complete.
Summary of the invention
The utility model aim is to overcome the shortcomings of above-mentioned prior art, is provided a kind of structurally reasonable, handy, efficient, fast
Victory can extract development machine motor spline housing quickly to ensure to produce fast quick-recovery normal development machine coal cutting portion motor disc type
Pulley extractor.
The utility model includes link block, semi-disc, fixture block, dead man, hydraulic jack and support plate；Link block is welded on half
At two outer ends of diameter line of disk, there are two link blocks up and down on each semi-disc；Semi-disc and fixture block are semicircular ring
Shape, fixture block semicircular ring outer diameter is identical as the internal diameter of semi-disc, and semi-disc is welded and fixed with semicircle fixture block, two semi-discs and its
Fixture block above is connected as an integral circular shape structure by link block and screw merging.Along disc radius line on semi-disc
Offer strip dead man connecting hole, support plate be directly with complete disk similar in semicircle disk diameter, along circle in support plate
Disk radius offers strip dead man connecting hole, and dead man connects hole site and connect hole site phase with dead man on semi-disc on disk
Mutually corresponding, fixed dead man is interspersed on disk on dead man connecting hole and semi-disc between dead man connecting hole and by matched dead man
Fixture nut is fixed, and hydraulic jack bottom is mounted in support disk center.The diameter of circular trough on fixture block semicircle ring diameter and shaft coupling
Match, preferably fixture block semicircular ring internal diameter is equal with the outer diameter of circular trough on shaft coupling.
In use, semicircle fixture block is blocked shaft coupling, screw by link block and its above connects two semi-discs
It connects and tightens together.Fixed dead man is through on disk on dead man hole and semi-disc between dead man hole and is consolidated by matching nut
Fixed, hydraulic jack bottom is mounted in support disk center, and top is against motor shaft.Suppressing to hydraulic jack generates hydraulic jack stretching, extension
One active force, makes support plate and motor shaft do reverse utilization, drives shaft coupling to be detached from motor shaft by fixed dead man and fixture block.
The utility model is simple and reasonable, facilitate it is handy quick, when carrying out pulling out wheel work, with traditional claw pulley extractor
It is more uniform compared to stress point, wheel uniform stressed during being detached from motor can be made.It is more easy so that extracting work, more
What is added is quick, can very easily extract motor wheel (shaft coupling), and be not easy to cause mechanical damage to motor, it is ensured that production
Fast quick-recovery is normal.Also more convenient in installation, traditional pulley extractor generally requires 2-3 people and cooperates regular worker
Make, and the utility model only needs a people.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is semi-disc structural schematic diagram；
In figure: 1, link block, 2, semi-disc, 3, fixture block, 4, shaft coupling, 5, hydraulic jack, 6, support plate, 7, fixation pull out
Bar, 8, motor shaft position, 9, dead man fixture nut, 10, dead man connecting hole.
Specific embodiment
Link block 1 is welded at two outer ends of diameter line of semi-disc 2, there is two connections up and down on each semi-disc 2
Block 1 is connected and fixed by the semi-disc of screw and another side, is made a whole disk and is embraced shaft coupling (motor wheel).
Support plate 6 be it is solid, directly connect by dead man 7 between semi-disc 2, give motor using hydraulic jack 5 among support plate 6
Axis active force extracts shaft coupling (motor wheel) by opposition.Fixture block 3 and semi-disc 2 are semicircular ring shape, fixture block 3
Semicircular ring overall diameter it is identical as the internal diameter of semi-disc 2, semi-disc 2 is welded and fixed with semicircle fixture block 3, two semi-discs 2 and
Fixture block 3 above it merges into an integral circular shape structure by link block 1 and screw connection.Along disk on semi-disc 2
Radius offers strip dead man connecting hole 10, and support plate 6 is directly to support with complete disk similar in 2 diameter of semi-disc
Strip dead man connecting hole is offered along disc radius line on disk 6, dead man connection hole site and dead man on semi-disc on disk
10 position of connecting hole corresponds to each other, fixed dead man 7 be interspersed on disk on dead man connecting hole and semi-disc dead man connecting hole 10 it
Between, and fixed by matched dead man fixture nut, 5 bottom of hydraulic jack is mounted in 6 center of support plate, and 5 top of hydraulic jack is right
The motor shaft at motor shaft position 8, suppressed to hydraulic jack 5 make hydraulic jack 5 stretching, extension generate an active force, make to prop up
Support plate 6 and motor shaft do reverse utilization, drive shaft coupling 4 to be detached from motor shaft by fixed dead man 7 and fixture block 3.
