Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of insulation caliper, comprising: vernier locking device 3 after insulating bar 1, vernier caliper 2 and survey.
Insulating bar is telescopic insulating bar.
Vernier caliper includes main scale 2.1, the vernier slide 2.2 being slidably arranged on main scale and outside diameter measuring structure.Main scale
It is connected with one end of insulating bar, specifically, main scale is rotatedly connected by shaft 4 and one end of insulating bar.Shaft and vernier are sliding
The glide direction of seat is perpendicular.Vernier slide, which is located at, to be determined between exterior measuring measuring jaw and shaft.
Outside diameter measuring structure includes the dynamic exterior measuring for determining exterior measuring measuring jaw 2.3 and be arranged on vernier slide being arranged on main scale
Measuring jaw 2.4.The length for determining exterior measuring measuring jaw is greater than dynamic exterior measuring measuring jaw.It is to determine base towards the side for determining exterior measuring measuring jaw for moving exterior measuring measuring jaw
Quasi- face 2.31.It include dynamic datum level 2.41 and guiding surface 2.42 towards the side for the dynamic exterior measuring measuring jaw for determining exterior measuring measuring jaw.Dynamic base
Quasi- face is between guiding surface and main scale.Dynamic datum level is parallel with datum level is determined.
What is connect with main scale determines one end of exterior measuring measuring jaw is defined as: determines the root of exterior measuring measuring jaw；Far from determining for main scale connection
One end of exterior measuring measuring jaw is defined as: determine the end of exterior measuring measuring jaw.Guiding surface and spacing between datum level is determined by determining external pelivimetry
The root of pawl is gradually increased toward the end direction for determining exterior measuring measuring jaw.
As shown in Figure 1 and Figure 2, vernier locking device includes the guide rail 3.1 being arranged on vernier slide, along guide rail cunning after survey
Dynamic sliding block 3.5, the triggering push rod 3.2 being arranged on sliding block, on setting vernier slide for by vernier sliding seat locking in main scale
On clamping screw 3.3, the driving gear 3.8 that is arranged on clamping screw and setting on triggering push rod and with driving gear phase
The rack gear 3.4 of engagement.The glide direction of sliding block and the glide direction of vernier slide are perpendicular.It is parallel with main scale to trigger push rod,
And push rod and main scale are triggered positioned at the same side of dynamic datum level.
Clamping screw, rack gear and driving gear are located at the same side of triggering push rod.Drive gear and clamping screw coaxial.Lock
Rubber block is additionally provided on the surface of the end of tight bolt.Rack gear is parallel with guide rail.The axis of clamping screw and guide rail are perpendicular,
The axis of clamping screw and triggering push rod are perpendicular.
Guide rail is equipped with the first limited block 3.6 and the second limited block 3.7.Sliding block is located at the first limited block and the second limited block
Between.First limited block and dynamic exterior measuring measuring jaw are located at the same side of triggering push rod, and the second limited block and dynamic exterior measuring measuring jaw are located at touching
Send out the opposite sides of push rod.
When sliding block is against on the first limited block: the end of clamping screw is separated with main scale, specifically, clamping screw
The rubber block of end is separated with main scale.
The specifically used as follows of caliper of insulating of the present embodiment:
First, the mobile sliding block of prospecting personnel is against sliding block on the first limited block, at this time the end of clamping screw and main scale
Separation；
Second, prospecting personnel hold insulating bar on ground, by vernier caliper close to high altitude wire to be calibrated；Then it will lead
Ruler is mobile toward conducting wire direction, is stuck in conducting wire and determines between datum level and guiding surface；
Third drives main scale to continue slowly mobile toward conducting wire direction by insulating bar, in this process:
It is mobile toward the separate direction for determining exterior measuring measuring jaw that conducting wire will first make exterior measuring measuring jaw and vernier slide, until conducting wire is located at
Until determining between datum level and dynamic datum level, after conducting wire, which is located at, to be determined between datum level and dynamic datum level, exterior measuring measuring jaw and trip are moved
It marks slide and stops movement；
Then, conducting wire will contact with triggering push rod and triggering push rod is driven to move along guide rail toward main scale direction, trigger push rod
Band carry-over bar moves together, to move clamping screw rotation by driving gear band, clamping screw is locked, rubber block is pressed
In scale surface；After rubber block is pressed on main scale, dynamic exterior measuring measuring jaw and vernier slide will be locked on main scale；
4th, prospecting personnel make vernier caliper and conducting wire by vernier caliper toward far from the movement of conducting wire direction by insulating bar
Separation；Then, vernier caliper is moved down, the diameter of high altitude wire is measured by vernier caliper.Due to moving external pelivimetry in the step
Pawl and vernier slide will be locked on main scale, and dynamic exterior measuring measuring jaw and vernier are sliding during vernier caliper up moves in this way
Seat does not move, to guarantee the accuracy of measurement.
The insulation caliper of the present embodiment can be in the case where not influencing conducting wire normal work, and accurately prospecting is led
The insulation caliper of line type and spec.
