Description
Technical field
The utility model relates to instrument transformer repairing technical field, especially a kind of instrument transformer recharging oil device.
Background technology
Current large-scale substation is very wide in whole nation distribution, oil starvation amount for 66KV and above its oil immersion type mutual-inductor of transformer station is very large, often need to safeguard repairing, need to prop metal expander when oiling and expose repairing hole, the method one of existing repairing is artificial, 3 people are adopted to cooperate, 2 people with the hands lift edge on metal expander, expander is opened, other 1 people firmly grasps repairing, because muscle power is limited, often just can complete the task of oiling several times, operating efficiency is low, another kind is that the end of vertical loading board is hinged with grapple, the outer of the corresponding metal expander video disc of hook end of grapple, in the process promoted, grapple edge that is easy and metal expander video disc is thrown off, if grapple and the disengagement of metal expander video disc can make metal expander video disc shrink in the process of oiling, cause the damage of oiling equipment.
Utility model content
The technical problems to be solved in the utility model is: metal expander can be made to shrink in order to overcome existing recharging oil device grapple and metal expander disengagement in the process of oiling, causing the deficiency of the damage of oiling equipment, now providing a kind of instrument transformer recharging oil device.
The utility model solves the technical scheme that its technical problem adopts: a kind of instrument transformer recharging oil device, comprise support, lift-bolt and arm, described lift-bolt is threaded with described support, lower end and the described arm of described lift-bolt are rotationally connected, the lower end surface of described lift-bolt is provided with guide vane end stop, the two ends of described arm slidably connect the first grapple and the second grapple respectively, threaded rod is provided with between described first grapple and the second grapple, the two ends of described threaded rod have the contrary screw thread of rotation direction, the two ends of described threaded rod are threaded with the first grapple and the second grapple respectively, the outer of the hook end of described first grapple and the equal corresponding metal expander video disc of the hook end of the second grapple, during rotating threaded rod the first grapple and the second grapple can relative away from or close, rotating threaded rod by the hook end of the first grapple and the second grapple close to each other make its tightly hook metal expander video disc, by rotating and upgrading screw rod by arm, rise together with first grapple and the second grapple and the metal expander video disc that hooks thereof.
Further, described first grapple and the second grapple are provided with T-shaped guide rail, described arm is provided with the T-slot matched with described T-shaped guide rail, described T-shaped slide is arranged in described T-slot.
For the ease of staff's rotating threaded rod, further, described threaded rod is provided with knob.
The beneficial effects of the utility model are: the first grapple and the second grapple are drawn close by threaded rod by instrument transformer recharging oil device of the present utility model mutually, make its hook end tightly hook metal expander video disc, avoid the problem that grapple and metal expander video disc come off in refueling process, the utility model structure is simple, cost is low, oiling efficiency is high, good stability and coefficient of safety high.
