Description
Technical field
The present invention relates to a kind of two-part clamp for being used to measure insulator rib groove internal diameter.
Background technology
The pollution degree measurement of insulator is the important process in antifouling work, and this has for the safe and stable operation of transmission line of electricity
It is significant.By carrying out the measurement of pollution degree after terminating in contamination season to insulator, operation maintenance personnel can be allowed to understand exhausted
The contamination situation of edge, to arrange the cleaning of insulator and replacing.The measurement work of insulator dirty degree is current power train
Emphasis in maintenance work of uniting, and each place divide dirty area's figure, design the important references of insulation system.
At present, 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 insulation subcategory of scene operation is various, the producer of manufacture
Often operations staff can't be given using surface area as the parameter of insulator, which results in operation maintenance personnel in measurement insulator
Pollution degree in meet difficulty.
The measurement of live insulator surface product passes through measurement typically using irregular surface to be divided into coaxial round platform
Surface area is obtained with the lateral area that calculates multiple round platforms.According to the lateral area formula of round platform, it is necessary first to obtain round platform upper table
Face and the diameter of lower surface.Because insulator surface is irregular shape, especially bell-shaped insulator lower surface has very
Deep rib groove, this just brings difficulty to the measurement of diameter.Traditional inside plain calipers and bow compass are due to its design feature, it is difficult to measure
The diameter of bell-shaped insulator lower surface regional area is used under insulator, it is necessary to targetedly design new segmented clamp
The measurement of surface diameter, to calculate insulator surface product.
The content of the invention
It is an object of the invention to provide a kind of two-part clamp for being used to measure insulator rib groove internal diameter, the clamp can not only
It is enough directly to snap at bell-shaped insulator rib groove depth, while the value of diameter can also be directly read using its graduated scale.
A kind of two-part clamp for being used to measure insulator rib groove internal diameter, it is particular in that：Including graduated scale, at this
Articulated column is installed among graduated scale, the top on the simultaneously be hinged top and right large arm for being provided with left large arm on the articulated column
End, the bottom of the left large arm and the top of left forearm are hinged, and the bottom of the right large arm and the top of right forearm are hinged, on the left side
The bottom of forearm and right forearm is each provided with a through hole, in addition to the first elater and the second elater, wherein the one of the first elater
Hold colligation on the through hole of left forearm bottom and the other end colligation of first elater on the scale, and the one of the second elater
Hold colligation on the through hole of right forearm bottom and second elater other end colligation on the scale.
Wherein be hinged is specifically to be movably riveted on together using rivet.
Wherein the first elater and the second elater use PBT false-twist textured yarns.
Wherein left large arm, left forearm, right large arm and right forearm use 304 stainless steels.
Gap is left between wherein the first elater and the second elater and graduated scale, so that first elater and the second bullet
Silk can move linearly relative to graduated scale length direction.
It is the intuitive measurement results of the present invention, reliable, forearm end is connected to by the PBT false-twist textured yarns on clamp during use
Through hole and graduated scale, false-twist textured yarn have good elasticity, can tightly entangle through hole and graduated scale.When clamp are stuck in insulation sublist
After position corresponding to face, the position of regulation false-twist textured yarn on the scale, make false-twist textured yarn vertical with graduated scale, now can basis
The position of false-twist textured yarn on the scale accurately reads the diameter of measurement point.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is use state diagram of the invention.
Embodiment
As shown in Figure 1, 2, the invention provides a kind of two-part clamp for being used to measure insulator rib groove internal diameter, including carve
Chi 1 is spent, articulated column 5 is installed among the graduated scale 1, is hinged the top for being provided with left large arm 2 simultaneously on the articulated column 5
End and the top of right large arm, the bottom and the top of left forearm of the left large arm 2 are hinged, and the bottom of the right large arm and right forearm 3
Top be hinged, a through hole 4, in addition to the first elater and the second bullet are each provided with the bottom of the left forearm and right forearm 3
Silk 6, wherein one end colligation of the first elater is on the through hole 4 of left forearm bottom and the other end colligation of first elater is being carved
Spend on chi 1, and one end colligation of the second elater 6 is on the through hole 4 of the right bottom of forearm 3 and the other end of second elater 6 is tied up
Prick on graduated scale 1.
Gap is left between wherein the first elater and the second elater 6 and graduated scale 1 so that the first elater and the second elater 6
It can be moved linearly relative to graduated scale length direction.
Wherein be hinged is specifically to be movably riveted on together using rivet, and the first elater and the second elater 6 are high-elastic using PBT
