Accompanying drawing explanation
Fig. 1 is the explosive view of the transformator disc type oil-immersed pump dismounting special purpose device of the present invention.
Fig. 2 is bracket and the generalized section of screw mandrel in Fig. 1.
Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
See Fig. 1, the transformator disc type oil-immersed pump of present invention dismounting special purpose device include slide rail 1, slide connect on slide rail 1 sliding platform 2, be arranged on the bearing 3 above sliding platform 2, be arranged on screw 4 above bearing 3 and the screw mandrel 5 that screw 4 is threadeded, be arranged on the supporting plate 6 above screw mandrel 5 and be arranged on the packing ring 7 above supporting plate 6.Supporting plate 6 is used for supporting disc type oil-immersed pump.
Slide rail 1 is rectangle, for sliding on for sliding platform 2.The production method of the slide rail 1 of the present embodiment is: first taking specification is four, 50mm*50mm angle steel, wherein two a length of 1500mm, another two a length of 500mm, termination docking assembly welding, i.e. forms the slide rail 1 being square.
Sliding platform 2 includes supporting the identical connecting shaft 21 of platform 20, two root architecture and the identical rotation wheel 22 of four structures.Supporting platform 20 to be made up of steel plate, it is provided centrally with through hole 23；Connecting shaft 21 is supported by round bar, is connected by welding manner is fixing with support platform 20；Rotating wheel 22 is ball bearing, is respectively sleeved at the two ends of connecting shaft 21.
Bearing 3 includes upper plate 30, lower plate 31, cylindrical seat 32 and the some support bars 33 being fixedly connected between upper plate 30 and lower plate 31.Upper plate 30 and lower plate 31 are made by steel plate, and the center of upper plate 30 and lower plate 31 is respectively provided with through hole (not shown), and two through holes are centrally located on same vertical line；Cylindrical seat 32, in hollow form, has centre bore, is fixedly installed on the top of upper plate 30, and its centre bore is corresponding with the through hole of upper plate 30 during installation.
Screw 4 is positioned at above cylindrical seat 32, and rotatable.Being provided with four handles 16 on screw 4 excircle equably, all use the round steel of diameter 10mm to make, the design of handle 16 can be easy to drive screw 4 to rotate.
Screw mandrel 5 is full silk screw rod, threadeds with screw 4, and inserts in cylindrical seat 32, may also pass through bearing 3 and sliding platform 2 simultaneously.When rotating screw 4, due to threaded characteristic, screw mandrel 5 can occur elevating movement.But in order to avoid screw mandrel 5 is with screw 4 synchronous axial system, the hole wall of the centre bore of cylindrical seat 32 arranges the first keyway (not shown) together, square toes key 11 is installed in first keyway, the outer wall of screw mandrel 5 arranges the second keyway (not shown) together, square toes key 11 snaps in the second keyway, so the rotary motion of screw mandrel 5 is limited, when rotating screw 4, it is ensured that screw mandrel 5 can only occur elevating movement.
Supporting plate 6 is made by steel plate, the concrete specification of the present embodiment be the length of side be the steel plate of 200mm.See Fig. 2, at lower central fixing welding one cylindrical sleeve 8 of supporting plate 6, four screws of the side opening of this cylindrical sleeve 8.During installation, screw mandrel 5 inserts in cylindrical sleeve 8, then uses bolt to be connected with each other at the axle journal of screw mandrel 5 through screw, thus realizes the supporting plate 6 flexible rotating at horizontal plane.Packing ring 10 ringwise, is arranged at supporting plate 6 upper center, to ensure the horizontal positioned of disc type oil-immersed pump.
The method using the special purpose device dismounting disc type oil-immersed pump of the present invention is as follows: slide rail 1 is first positioned over the lower section of oil-immersed pump to be torn open, and aliging with the centrage of disc type oil-immersed pump in the center of slide rail 1, one end is stretched out outside radiator, it is simple to oil-immersed pump is pulled down tailing edge track and skidded off.Remainder assembling being put in place successively, then whole device is slid into oil-immersed pump center, pull handle 16 and rise to bottom disc type oil-immersed pump by supporting plate 6, the fixing bolt of i.e. detachable disc type oil-immersed pump, disc type oil-immersed pump departs from, and is supported by supporting plate 6.The most reversely pull handle 16, disc type oil-immersed pump slowly can be fallen so that it is leave the radiator of transformator, slowly skid off overall together with disc type oil-immersed pump for sliding platform 2 along slide rail 1 the most again, can steadily be safely completed the dismounting of disc type oil-immersed pump.
The method that the special purpose device using the present invention installs disc type oil-immersed pump is contrary with the order of method for dismounting.
In sum, the transformator disc type oil-immersed pump dismounting special purpose device of the present invention has some advantage following:
1, the combination of this device bulk-breaking, easy to carry, easily takes care of.
2, simple in construction, easy to operate, can split out and go back to loading position easily, quickly by disc type oil-immersed pump entirety, improve work efficiency, reduce labor intensity, strengthen the safety of work, convenient maintenance.
3, due to rational in infrastructure, using this device, being positioned by disc type oil-immersed pump of energy accurate quick, during installation, equipment is steadily without tilting, and facilitates the para-position of disc type oil-immersed pump flange face to hole, it is ensured that equipment level splits out and installs, it is to avoid flange face sealing part shifts or damages.
4, lifting rope binding or people the most in the past lifts method, and owing to special purpose device can ensure that the light and slow level of disc type oil-immersed pump enters position, flange face para-position is reliable, and security performance is greatly improved, and during can effectively avoiding manually lifting shifting, device fall is damaged and the accident of casualties.
It is pointed out that above-mentioned preferred embodiment is only technology design and the feature of the explanation present invention, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
