Description
Technical field
The utility model relate to a kind of on tension tester the frock of clamping chapeau de fer.
Background technology
Plate-shaped suspension type insulator (hereinafter to be referred as insulator) is for the insulation in the high voltage overhead electric line and fixing cord.Insulator generally is comprised of parts such as steel pin, skirt shape glass workpiece, chapeau de fers.Because the hi-line event of must stopping to go offline occurs, so the intensity of insulator all parts must be guaranteed.Before the assembling insulator, all must do the sampling tensile test to all parts.
As Fig. 1, chapeau de fer one end is the ball-and-socket 8 that is connected with steel pin ball head, and the other end is the cap nest 7 of assembling skirt shape glass workpiece; Be provided with the Antiskid platform 9 of annular in described cap nest 7.
Because the chapeau de fer shape is special, existing tension tester can't carry out clamping to it.
The utility model content
For the technical matters of above-mentioned existence, the utility model provides a kind of chapeau de fer tensile test frock, and the clamping chapeau de fer carries out tensile test easily.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of chapeau de fer tensile test frock comprises the upper end-fixture that is connected with the tension tester tensioning member respectively, the lower end fixture that is connected with the tension tester fixture; Described upper end-fixture comprises a conical seat; Described conical seat bottom is provided with the step of annular, and the upper end is provided with the screw mandrel that is connected with the tension tester tensioning member; Also comprise some filling blocks, described filling block is placed on conical seat, and its inside surface surrounds and the corresponding cavity of conical seat; Described filling block is outside equipped with the annular anti-slop serrations that coordinates with the chapeau de fer Antiskid platform; Described lower end fixture comprises base, and described base rear end has the silk hole that is connected with the tension tester fixture, and the base front end is provided with pull bar; Described pull bar front end is provided with the pull head that coordinates with the chapeau de fer ball-and-socket.
As a kind of improvement, described filling block relies on flexible bungee to be bound on conical seat.Make after carrying out tensile test, filling block is unlikely to be scattered, and because bungee is flexible, also can not hinder filling block to move up and down.
As a kind of preferred, the bottom surface diameter of the cavity that described filling block surrounds is less than the diameter of conical seat bottom surface.Like this, when carrying out tensile test, filling block makes pulling force larger toward lower slider and expansion, and clamping is tighter.Avoid filling block to come off from chapeau de fer cap nest.
As a kind of preferred, described filling block is pintongs.
Usefulness of the present utility model is:
Frock with said structure, the clamping chapeau de fer carries out tensile test easily, and it is simple in structure, is suitable for practicality.
Description of drawings
Fig. 1 is the schematic diagram of chapeau de fer.
Fig. 2 is the structural representation of facing of upper end-fixture.
Fig. 3 is the plan structure schematic diagram of upper end-fixture.
Fig. 4 is lower end clamp structure schematic diagram.
Mark in figure: 1 conical seat, 2 steps, 3 screw mandrels, 4 filling blocks, 5 anti-slop serrations, 6 bungees, 7 cap nests, 8 ball-and-sockets, 9 Antiskid platforms, 10 pull bars, 11 pull heads, 12 bases, 13 holes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Fig. 2-4:
The utility model comprises the upper end-fixture that is connected with the tension tester tensioning member respectively, the lower end fixture that is connected with the tension tester fixture; Described upper end-fixture comprises a conical seat 1; Described conical seat 1 bottom is provided with the step 2 of annular, and the upper end is provided with the screw mandrel 3 that is connected with the tension tester tensioning member; Also comprise some filling blocks 4, described filling block 4 is placed on conical seat 1, and its inside surface surrounds and the corresponding cavity of conical seat 1; Filling block 4 is preferably pintongs and relies on flexible bungee 6 to be bound on conical seat 1.The bottom surface diameter of the cavity that filling block 4 surrounds is less than the diameter of conical seat 1 bottom surface.Described filling block 4 is outside equipped with the annular anti-slop serrations 5 that coordinates with chapeau de fer Antiskid platform 9; Described lower end fixture comprises base 12, and described base 12 rear ends have the silk hole 13 that is connected with the tension tester fixture, and base 12 front ends are provided with pull bar 10; Described pull bar 10 front ends are provided with the pull head 11 that coordinates with chapeau de fer ball-and-socket 8.
When using, at first upper end-fixture is put into cap nest 7, then with filling block 4 along conical seat 1 toward lower slider, make filling block 4 constantly expand, until tighten with chapeau de fer Antiskid platform 9.Then the pull head 11 of lower end fixture is hung chapeau de fer ball-and-socket 8, just can carry out tensile test.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
