Description

A kind of spanner for middle high-voltage circuitbreaker oil bumper

Technical field

It is specifically a kind of high for middle the utility model relates to middle high-voltage circuitbreaker oil bumper maintenance tool The spanner of voltage breaker oil bumper.

Background technique

When middle high-voltage circuitbreaker is in division than under more frequently operating conditions, the cylinder cap of oil bumper is easy to happen It loosens, limits its piston rod stroke, cause breaker closing to keep pawl that cannot clasp semiaxis, " refused to generate breaker The phenomenon of the failure of conjunction "；Occur to need to tighten cylinder cap when the phenomenon, the narrow space as locating for oil bumper, a hand is all It is difficult to put in, as seen in figs. 5-6, oil bumper is designed with spatial clapboard 8 by periphery in breaker, leads to its operating space It is very narrow, when cylinder cap 6 loosens, it is difficult to repair, several skilled practitioners is needed gradually to tear breaker open at present Solution, the compact complexity of breaker structure, the assembly of each component is closely linked, and it is more than hour to need two for dismantling work time-consuming, imitates Rate is very beneath, seriously affects production efficiency.

Summary of the invention

The purpose of this utility model is exactly to seriously affect life to solve the cylinder cap generation loosening of oil bumper and be difficult to repair The problem of producing efficiency, provides a kind of spanner for middle high-voltage circuitbreaker oil bumper.

The concrete scheme of the utility model is: a kind of spanner for middle high-voltage circuitbreaker oil bumper, packet Wrench body and handle are included, wrench body includes U-board, and U-board is set on one side there are two the positioning pin outwardly protruded, and two position The distance between the distance between pin cylinder cap location hole of oil bumper matches so that wrench body can be put into oil bumper Cylinder cap on and drive cylinder cap to rotate, the lateral surface of U-board is evenly provided with several handle sockets, and described handle one end is equipped with Bolt, bolt matched with handle socket so that handle capable of being freely be inserted or pulled out handle socket.

Handle socket described in the utility model is round or regular polygon, bolt and the handle socket shape phase of the handle Together.

Clearance fit between handle socket and bolt described in the utility model, fit clearance are 0.2 ~ 0.5mm.

Clearance fit between positioning pin and cylinder cap location hole described in the utility model, fit clearance are 0.2 ~ 0.5mm.

Utility model works principle is as follows: being fastened using the symmetrical location hole of cylinder cap to cylinder cap, by handle The position that adjustment wrench body at cylinder cap is sent to after insertion wrench body makes two positioning pins of wrench body be put into determining for cylinder cap In the hole of position, then swing handle makes wrench body that cylinder cap rotation be driven to tighten, during tightening if stroke not enough if handle torn open It carries out repeatedly tightening movement in the handle socket of rear end in lower insertion wrench body.

The utility model has the advantage that compared with prior art to be operated in narrow space, avoid big It is easy to operate, upper quick-moving when dismounting work, significant increase maintenance efficiency, and using, general operation personnel are carried out simple Training, so that it may which complete independently can complete whole operation in 10 minutes.

Specific embodiment

Referring to Fig. 1-4, the present embodiment includes wrench body 1 and handle 2, and wrench body 1 includes U-board, and U-board is set on one side There are two the positioning pins 3 that outwardly protrude, between the distance between two positioning pins 3 and 6 location hole 7 of cylinder cap of oil bumper away from From matching so that wrench body 1 can be put on the cylinder cap 6 of oil bumper and cylinder cap 6 is driven to rotate, the lateral surface of U-board is uniform Ground is equipped with several handle sockets 4, and described 2 one end of handle is equipped with bolt 5, and bolt 5 is matched with handle socket 4 so that 2 energy of handle Freely be inserted or pulled out handle socket 4.

Handle socket described in the present embodiment is square (being also possible to regular polygon after circle), the bolt 5 of the handle 2 It is identical as 4 shape of handle socket.

Clearance fit between handle socket 4 and bolt 5 described in the present embodiment, fit clearance are that 0.2 ~ 0.5mm(is specifically 0.4mm).

Clearance fit between 6 location hole 7 of positioning pin 3 described in the present embodiment and cylinder cap, fit clearance are 0.2 ~ 0.5mm(tool Body is 0.4mm).
