Abstract
A kind of on load tap changer core bucket extracting tool, comprise the horizontal stand of " ten " font, four the vertical through holes be arranged symmetrically with are provided with in the outside of described support, corresponding screw rod is installed with respectively in described vertical through hole, described screw rod is respectively equipped with screw thread and lower screw thread, the upper threaded portion of described screw rod upwards passes described support, and be threaded connection top nut and lower nut at the upper screw thread place of described screw rod, described support is between upper and lower nut.
Description
Technical field
The utility model relates to a kind of on-load tap switch maintenance apparatus field, particularly a kind of on load tap changer core bucket extracting tool.
Background technology
On load tap changer is a kind of switching device providing constant voltage when transformer load changes, during installation, the core bucket of on load tap changer to be penetrated from bottom to top in the centre bore of overcoat and to be fixed by bolt and overcoat, during work, on load tap changer needs continuous action and cuts off load current, act frequently, and due to reasons such as on load tap changer manufacturing process, installation, service conditionss, cause failure rate higher, often will dismantle, overhaul.
The mode of current dismounting core bucket is opened by the bolt that core bucket is connected with overcoat, and hook core bucket by crane and slowly discharge downwards, thus be separated with overcoat by core bucket.This dismounting mode operating personnel are more, and because substation is complicated, vacant lot area is little and equipment is more, particularly indoor transformer, crane dismounting is inconvenient, and the more difficult control of the strength of crane, easily cause damage and the operator safety danger of on load tap changer.
Summary of the invention
The utility model is to solve the problems of the technologies described above, and provides one can reduce operating personnel, convenient disassembly, minimizing on load tap changer damage occurrence probability, improves the on load tap changer core bucket extracting tool of the fail safe of dismantling the operation in planting.
Technical solution of the present utility model is: a kind of on load tap changer core bucket extracting tool, its special character is: the horizontal stand comprising " ten " font, four the vertical through holes be arranged symmetrically with are provided with in the outside of described support, corresponding screw rod is installed with respectively in described vertical through hole, described screw rod is respectively equipped with screw thread and lower screw thread, the upper threaded portion of described screw rod upwards passes described support, be threaded connection top nut and lower nut at the upper screw thread place of described screw rod, described support is between upper and lower nut.
Described through hole is strip hole, is convenient to the position of adjusting screw(rod).
The beneficial effects of the utility model are: because support is " ten " font, uniform force, Stability Analysis of Structures; Support is seated in the overcoat top of on load tap changer, and screw rod is fixedly mounted on the core bucket of on load tap changer by lower screw thread, turning upper and lower nut makes screw rod opposite brackets move downward, thus the core bucket of on load tap changer is slowly separated downwards from overcoat, structure is simple, carries, convenient disassembly, decreases operating personnel's quantity, reduce the damage probability of on load tap changer, improve the fail safe of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is using state schematic diagram of the present utility model;
In figure: 1-support, 2-through hole, 3-screw rod, the upper screw thread of 301-, screw thread under 302-, 4-top nut, 5-lower nut, 6-overcoat, 7-core bucket.
Embodiment
As shown in the figure, a kind of on load tap changer core bucket extracting tool, comprise the support 1 of " ten " font, on described support 1, four outside portions are respectively equipped with the through hole 2 of corresponding vertical direction, described through hole 2 is strip hole, in described through hole 2, be installed with corresponding screw rod 3 respectively, described screw rod 3 is respectively equipped with screw thread 301 and lower screw thread 302, and the upper and lower being positioned at support 1 at upper screw thread 301 place of described screw rod 3 is provided with top nut 4 and lower nut 5.
During operation, first the connecting bolt corresponding with support 1 between the overcoat 6 of on load tap changer and core bucket 7 is unloaded, then support 1 is seated in the top of overcoat 6, and screw rod 3 is arranged in screwed hole corresponding on core bucket 7 by lower screw thread 302, fix with core bucket 7, again other bolts that core bucket 7 is connected with overcoat 6 are unloaded, and upwards turn upper and lower nut 4,5 screw rod 3 opposite brackets 1 is moved downward, thus the core bucket 7 of on load tap changer is slowly separated downwards from overcoat 6, complete operation.
These are only specific embodiment of the utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
Claims (2)
1. an on load tap changer core bucket extracting tool, it is characterized in that: the horizontal stand comprising " ten " font, four the vertical through holes be arranged symmetrically with are provided with in the outside of described support, corresponding screw rod is installed with respectively in described vertical through hole, described screw rod is respectively equipped with screw thread and lower screw thread, the upper threaded portion of described screw rod upwards passes described support, and be threaded connection top nut and lower nut at the upper screw thread place of described screw rod, described support is between upper and lower nut.
