Description
Technical field
The utility model relates to power industry distribution line equipment mounting tool, specifically a kind of network distribution transformer shunting switch special spanner, for the upkeep operation of network distribution transformer shunting switch.
Background technology
In the upkeep operation of transmission line of electricity network distribution transformer shunting switch, often run into shunting switch fuse rotating shaft place oil leakage fault, this place's leakage of oil main cause is because aging loosening appears in sub-connecting switch of transformer sealing gasket.And sub-connecting switch of transformer sealing gasket maintenance position is special, for 10kV network distribution transformer shunting switch, its sealing nut periphery is laid with the equipment such as various high-low pressure porcelain vase, lead-in wire, use the instrument maintenance such as existing spanner, workmen need to stretch into from the gap of the equipment such as porcelain vase carry out dismantling, tightening operation, moment is subject to porcelain vase and lead-in wire stop cannot fully be had an effect, and occurs fastening phenomenon not in place, operating difficulties, wastes time and energy.In addition conventional spanner fastening means, spanner bayonet socket cannot fit tightly with shunting switch sealing nut, very easily occurs slippage in operating process, cause that staff is injured, Switch main body and porcelain vase impaired.
Owing to there is above-mentioned defect, therefore at the scene conditions permit when, suspended core process is adopted usually to the maintenance of sub-connecting switch of transformer oil leakage fault, device body of namely slinging, changes a new switch.But there is following shortcoming in this processing method: low-tension bushing leakage of oil may be caused during dismounting low-voltage bus bar; Case lid sealing not easily processes; Need dismounting high-low voltage leads, at least need to have a power failure more than half a day.Therefore need to develop a kind of specific purpose tool for sub-connecting switch of transformer dismounting fuse sealing clamping nut, to solve the problems such as current shunting switch leakage of oil maintenance efficiency of construction is low.
Summary of the invention
The purpose of this utility model is to provide a kind of special spanner for dismounting network distribution transformer shunting switch sealing clamping nut.
The purpose of this utility model is achieved through the following technical solutions:
Network distribution transformer shunting switch special spanner, comprises spanner, the support bar for transmitting torque, hand lever; Spanner is horizontally disposed with, each vertical connection in bayonet socket both sides support bar of spanner upper surface, and hand lever is fastened on the top of two support bars; Described support bar is made up of core bar, loop bar, and what core bar can pull and push is inserted in loop bar, and is located by jackscrew.
Further, described spanner is U-shaped structure.
Further, described hand lever is made up of crossbeam and two handles, and handle is articulated and connected at crossbeam two ends, and can swing in vertical plane; Crossbeam is connected with support bar.
Further, the crossbeam of described hand lever and handle junction are provided with and limit the limited block of handle to lower swing.
Further, be fixed with between the loop bar of described support bar and strengthen connecting rod or connecting plate.
Further, described core bar is connected with spanner, and loop bar is connected with hand lever.
The beneficial effects of the utility model are: simple and reasonable, easy to operate; Spanner is connected with support bar and hand lever plug-in mounting, the spanner of replaceable different size bayonet socket, coordinates the equipment of all size, to guarantee fitting tightly of bayonet socket and switchgear; This device changes traditional fastening means, overcome defect of the prior art, force hand lever is arranged on the top of stress point sealing nut, thus avoids the interference of the equipment such as sealing nut periphery high-low pressure porcelain vase and lead-in wire, workmen firmly evenly, improves operating efficiency and repair quality.In addition, the handle portion of hand lever is collapsible to be packed up, and is convenient to this instrument and passes through between porcelain vase etc., be convenient for carrying simultaneously and store in construction.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In figure: 1, spanner, 2, support bar, 21, core bar, 22, loop bar, 3, hand lever, 31, crossbeam, 32, handle, 4, strengthen connecting rod.
Embodiment
As can be seen from Figure 1, technical solutions of the utility model comprise spanner 1, the support bar 2 for transmitting torque, hand lever 3; Described hand lever 3 is made up of crossbeam 31 and two handles 32, handle 32 can in vertical plane longitudinal oscillation be articulated and connected at crossbeam 31 two ends; The crossbeam 31 of described hand lever is provided with the junction of handle 32 and limits the limited block of handle to lower swing, and make handle 32 be rocked to horizontal level (be a straight line with crossbeam) stop, namely handle upwards swings only.
Described support bar 2 is made up of core bar 21, loop bar 22, and core bar 21 is inserted in loop bar 22, along axial sliding movement expansion fit (what in the present embodiment, core bar 21 epimere can pull and push is inserted in loop bar 22), and is located by jackscrew.
Described spanner 1 is U-shaped hatch frame, and is horizontally disposed with, and spanner can arrange the bayonet socket of plurality of specifications, to coordinate the switchgear of different size; The each vertical connection in bayonet socket both sides support bar 2 of spanner 1 upper surface, in this example, spanner 1 and the lower end of core bar 21 are by being welded to connect, and loop bar 22 top (i.e. the top of two support bars 2) is connected and fixed by the crossbeam 31 of welding with hand lever 3.
Be fixed with between the loop bar 22 of described support bar 2 and strengthen connecting rod 4 or connecting plate, prevent support bar 2 stress deformation in construction.
When the utility model uses, select suitable spanner assembling tool according to switchgear specification, regulated the height of hand lever in assembling process by core bar 21 and loop bar 22, make it higher than porcelain vase, lead-in wire etc.By the bayonet socket inlay card of spanner on the sealing clamping nut (platen) of shunting switch, to both sides deploying handles, press down and firmly pull handle drive spanner unscrew or fit sealing clamping nut.Use this instrument to construct, avoid the impact on the spanner arm of force (hand lever) such as high-low pressure porcelain vase, add the scope of activities of hand lever, staff can evenly exert a force by both hands, significantly improves efficiency of construction and repair quality.
Finally should be noted that: above embodiment is not intended to limit for illustration of the technical solution of the utility model; those skilled in the art modifies to embodiment or carries out equivalent replacement to portion of techniques feature; and do not depart from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
