Abstract
The utility model discloses a spanner which disassembles and assembles the GW4-110-type disconnector vertical linkage bearing cover plate. The utility model consists of a handle (1) and a semi-round frame (2) arranged at one end of the handle; two ends ringent externally of the semi-round frame are respectively provided with a grapping fixture (3). When the spanner is blocked in two symmetrical holes of the cover plate, the cover can be convenient to be rotated, to implement the disassembly and assembly of the cover plate.
Description
Technical field
The utility model belongs to the electric equipment specific purpose tool, is specially adapted to the dismounting of GW4-110 type isolating switch vertical links bearing shell cover plate.
Background technology
GW4-110 type isolating switch is a kind of switch that power industry particularly is widely adopted in electric substation, for making its safe operation, the overhaul of every 4-5 palpus once, vertical links bearing shell cover plate on it is a disc, there is a circular hole of wearing the vertical links bearing shell centre, even layout has four small sircle holes around the circular hole, the bearing shell cover plate is that screw thread by periphery is fixed on the chassis at ordinary times, need take off cover plate during maintenance, because long-term corrosion, it is extremely difficult to take off cover plate during dismounting, and common way is the method for pounding with punching pin and hammer, and this kind method is easy to component wear.
Summary of the invention
The purpose of this utility model provides a kind of spanner of dismounting GW4-110 type isolating switch vertical links bearing shell cover plate, uses this spanner can be easily with the dismounting of bearing shell cover plate.
The utility model is realized with following technical scheme: this spanner is made up of at the semi-round ring shape support of handle one end handle and device, on two outside open terminations of semi-round ring shape support a grappling fixture is arranged respectively, the spacing between two grappling fixtures equates with the spacing that switch shaft FE Tiler plate connects between the symmetrical holes.As long as two grappling fixtures with this spanner during use insert in the symmetrical small sircle hole of cover plate, pulling handle is rotating plate easily, and cover plate is taken off.
Its good effect is: owing to adopted technique scheme, when two grappling fixtures of the present utility model are snapped in the cover board hole, pull handle by hand of spiral, can easily cover plate be backed out or tighten, the utlity model has advantage simple in structure, easy to use.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Among the figure: 1, handle, 2. support, 3. grappling fixture.
The specific embodiment
See figures.1.and.2, the utility model is made up of handle (1), the semi-round ring shape support (2) that is contained in handle (1) one end, and support (2) also can be made outwards open other shapes.Respectively stretch out a cylindrical grappling fixture (3) on a company termination of support (2), the spacing on the spacing between two grappling fixtures (3) and the switch shaft FE Tiler plate between two symmetrical holes equates, easily grappling fixture is inserted in two holes.
Claims (2)
1, a kind of spanner of dismounting GW4-110 type isolating switch vertical links bearing shell cover plate, it is characterized in that forming at the semi-round ring shape support (2) of handle one end, on two outside open terminations of semi-round ring shape support, a grappling fixture (3) is arranged respectively by handle (1) and device.
2, the spanner of dismounting GW4-110 type isolating switch vertical links bearing shell cover plate according to claim 1 is characterized in that the spacing between two symmetrical holes of spacing and switch shaft FE Tiler plate between two grappling fixtures (3) equates.
