Description
Technical field
The present invention relates to a kind of barrel support toolings.
Background technique
The bus bar canister that combined electrical apparatus is closed in full packing is required to carry out pressure test before factory, as shown in Figure 1, pressure test
Equipment includes high pressure generator 100, and the side of high pressure generator 100 is connected with the horizontally extending connector 200 of axis, connects
Conducting wire is coaxially equipped in first 200, the end of connector 200 is equipped with abutted flange 300.When test, bus bar canister is horizontally disposed, bus
One end of cylinder is connected by flange and connector, and the other end is supported using supporting tool 500.Bus bar canister and pressure test equipment
After connection, the conducting wire inside bus bar canister 400 is docked with the conducting wire in connector, and the high-voltage electricity that high pressure generator 100 generates is by connecing
First 200 conduction can carry out pressure test to bus bar canister 400.
Existing supporting tool includes bracket and the V-block for being fixed on cradle top, in use, bus bar canister is horizontal positioned
In the V-groove of V-block.Since the connector center height of pressure test equipment is fixed, and to be tested bus bar canister specification
Difference, diameter vary, can be with pressure test device junction in order to meet the centre-height of different-diameter bus bar canister
Centre-height is consistent, and realizes bus pipe and pressure test equipment interconnection, it is necessary to which the bus bar canister of different-diameter is corresponding different
Bearing height.It is female if the bus bar canister to be supported is relatively large in diameter since the V-groove angle of a V-block is certain
After spool is placed on V-block, the support angle of V-block can not be adapted with the diameter of bus bar canister, and it will cause supports not
Stable problem；In addition the diameter increase of bus bar canister is increased along with center, this just needs to reduce the bearing height of supporting tool,
Since supporting tool support is unstable, it be easy to cause bus bar canister to fall during adjusting bearing height and in turn results in outside bus bar canister
Portion's structural damage.And when the diameter of bus bar canister is smaller, although V-block can stablize bus bar canister and support, but there is V
The diameter of type block and bus bar canister mismatches and causes the centre-height of bus bar canister relatively low.In order to make the diameter of V-block and bus bar canister
Matching, usual same V-block can only support the bus bar canister of one two kinds of different sizes, for the bus bar canister compared with plurality of specifications,
It just needs to manufacture more set supporting tool, therefore needs a kind of supporting tool that can be matched with the bus bar canister of multiple diameter.
Summary of the invention
