Description
Technical field
The utility model relates to a kind of bending strength test frock, and specifically a kind of 110kV composite sheath bending strength test frock, is applicable to 110kV composite sheath bending strength test.
Background technology
110kV composite sheath is widely used in cross-linked polyethylene insulated cable terminal, major part is all arranged on cable Ji Ta, can be subject to beam wind and cable lateral pull, so have certain bending strength requirement to composite sheath, composite sheath dispatches from the factory and must do four-way beam test.
Summary of the invention
The purpose of this utility model is to provide a kind of 110kV composite sheath bending strength test frock, this test fixture structure is simple, floor area is little, use this test fixture to carry out bending strength test to composite sheath, easy and simple to handle, product can realize axial-rotation and complete four-way beam test.
The purpose of this utility model is achieved through the following technical solutions:
A kind of 110kV composite sheath bending strength test frock, comprise testing jig, movable trolley, described testing jig comprises base, is arranged on the column of base side, and described column is provided with mounting flange; The opposite side of described base is provided with hydraulic jack, push-pull effort sensor and nylon cushion block from below to up successively; Top 4 end of described movable trolley is respectively equipped with roller.
Described 110kV composite sheath bending strength test frock also comprises back up pad, and described back up pad is fixed on base surface thereof support post.
Described testing jig is welded by base, column and back up pad.
The material of described testing jig is H steel.
Described 110kV composite sheath bending strength test frock also comprises force value feedback extension line, and described push-pull effort sensor is connected with Portable digital display tautness meter or computer terminal through force value feedback extension line, the display that when realizing testing, force value exports.
During use, 110kV composite sheath is loaded onto movable trolley, by roller supporting, one end of 10kV composite sheath is fixed by mounting flange, the other end is placed on nylon cushion block, regulate hydraulic jack to carry out anti-bending test, force value feeds back to Portable digital display tautness meter or computer terminal; Unload composite sheath from mounting flange again, by composite sheath axial rotary 90 degree, then fixed by mounting flange, carry out anti-bending test; Repeat the operation of above-mentioned anti-bending test, until composite sheath completes four-way beam test.
The beneficial effects of the utility model:
The utility model 110kV composite sheath bending strength test tool structure is simple, floor area is little, this test fixture is used to carry out bending strength test to composite sheath, easy and simple to handle, product can realize axially 360 ° of rotations and complete four-way beam test, force value during Real-time Obtaining test.
