The contamination situation of edge, to arrange the cleaning and replacement of insulator.The measurement work of insulator dirty degree is current power train
The important references that emphasis and each place in maintenance work of uniting divide dirty area figure, design insulation system.
Currently, the pollution degree of insulator is characterized with equivalent salt density (ESDD) and ash close (NSDD), but both parameters
Measurement all have to the surface area of insulator as parameter.But the insulator of scene operation is many kinds of, the producer of manufacture
Often operations staff can't be given using surface area as the parameter of insulator, which results in operation maintenance personnels in measurement insulator
Pollution degree in meet difficulty.
The measurement of live insulator surface product passes through measurement generally using irregular surface to be divided into coaxial rotary table
Surface area is obtained with the lateral area that calculates multiple rotary tables.According to the lateral area formula of rotary table, it is necessary first to obtain table on rotary table
The diameter in face and lower surface.Since insulator surface is irregular shape, especially bell-shaped insulator lower surface has very
Deep rib slot, this just brings difficulty to the measurement of diameter.Traditional inside plain calipers and bow compass is due to its design feature, it is difficult to measure
The diameter of bell-shaped insulator lower surface regional area needs targetedly to design new segmented clamp under insulator
The measurement of surface diameter, to calculate insulator surface product.
Utility model content
The purpose of the utility model is to provide a kind of for measuring the two-part clamp of insulator rib slot internal diameter, and the clamp are not
It only can directly snap at bell-shaped insulator rib groove depth, while also can use the value that its graduated scale directly reads diameter.
It is a kind of for measuring the two-part clamp of insulator rib slot internal diameter, its special feature is that: including graduated scale, at this
It is fixedly installed with hinge column among graduated scale, the top of left large arm and the top of right large arm are hingedly installed simultaneously on the hinge column
End, the bottom end of the left large arm and the top of left forearm are hinged, and the bottom end of the right large arm and the top of right forearm are hinged, on the left side
The bottom end of forearm and right forearm is each provided with a through-hole, further includes the first elater and the second elater, wherein the one of the first elater
End binding is on the through-hole of left forearm bottom end and the other end of first elater is bound on the scale, and the one of the second elater
End binding is on the through-hole of right forearm bottom end and the other end of second elater is bound on the scale.
Wherein hinged is specifically to be movably riveted on together using rivet.
Wherein the first elater and the second elater are all made of PBT high stretch yarn.
Wherein left large arm, left forearm, right large arm and right forearm are all made of 304 stainless steel materials.
Wherein there are gaps between the first elater and the second elater and graduated scale, to make first elater and the second bullet
Silk can move linearly relative to graduated scale length direction.
It is the intuitive measurement results of the utility model, reliable, forearm end is connected to by the PBT high stretch yarn on clamp when use
The through-hole and graduated scale in portion, high stretch yarn have good elasticity, can tightly entangle through-hole and graduated scale.When clamp are stuck in insulation
After the corresponding position in sublist face, high stretch yarn position on the scale is adjusted, keeps high stretch yarn vertical with graduated scale, it at this time can be with
The diameter of measurement point is accurately read according to the position of high stretch yarn on the scale.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is the use state diagram of the utility model.
Specific embodiment
As shown in Figure 1, 2, the utility model provides a kind of for measuring the two-part clamp of insulator rib slot internal diameter, wraps
Graduated scale 1 is included, is fixedly installed with hinge column 5 among the graduated scale 1, left large arm 2 is hingedly installed simultaneously on the hinge column 5
Top and right large arm top, the bottom end of the left large arm 2 and the top of left forearm are hinged, and the bottom end of the right large arm and the right side are small
The top of arm 3 is hinged, is each provided with a through-hole 4 in the bottom end of the left forearm and right forearm 3, further includes the first elater and second
Elater 6, wherein one end of the first elater is bound on the through-hole 4 of left forearm bottom end and the binding of the other end of first elater exists
On graduated scale 1, and one end of the second elater 6 is bound on the through-hole 4 of right 3 bottom end of forearm and the other end of second elater 6
Binding is on graduated scale 1.
Wherein there are gaps between the first elater and the second elater 6 and graduated scale 1 to make the first elater and the second elater 6
It can move linearly relative to graduated scale length direction.
Wherein hinged is specifically to be movably riveted on together using rivet, and it is high-elastic that the first elater and the second elater 6 are all made of PBT
