Problems solved by technology
The on-site survey work is only the preparatory work. It is impossible for the surveyors to climb the power pole to measure the wire type and specification after the power failure of the line. Judging the wire type and specification based on experience has a high error rate; or after returning to the office to check the information, the wire type and specification are determined, but because the data is not updated in time or due to poor storage, there are many mistakes in the judgment of the wire type and specification

Embodiment Construction
[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0021] Such as figure 1 As shown, an insulating caliper includes: an insulating rod 1 , a vernier caliper 2 and a vernier locking device 3 after measurement. The insulating rod is a telescopic insulating rod.
[0022] The vernier caliper includes a main ruler 2.1, a vernier slide seat 2.2 slidably arranged on the main ruler and an outer diameter measuring structure. The main chi is connected to one end of the insulating rod, specifically, the main chi is rotatably connected to one end of the insulating rod through the rotating shaft 4 . The rotating shaft is perpendicular to the sliding direction of the vernier slide seat. The vernier sliding seat is located between the fixed outer measuring claw and the rotating shaft.
[0023] The outer diameter measuring structure includes a fixed outer measuring claw 2.3 arranged on the main ruler and a ...

The invention discloses an insulation caliper unit and aims at providing an insulation caliper unit that is capable of surveying the type and specification of a conductor accurately while the normal working of the conductive line are not affected. The insulation caliper unit comprises an insulation rod, a vernier caliper, and an after-measurement vernier locking device. The vernier caliper consists of a main ruler, a vernier sliding base arranged on the main ruler in a sliding mode, and an outer diameter measuring structure; the main ruler is connected with one end of the insulation rod; and the outer diameter measuring structure includes a fixed external measuring claw arranged on the main ruler, and a moving external measuring claw arranged on the vernier sliding base. The after-measurement vernier locking device consists of a guide rail arranged on the vernier sliding base, a sliding block sliding along a guide rail, a trigger push rod arranged on the sliding block, a locking bolt being arranged on the vernier sliding base and being used for locking the vernier sliding base at the main ruler, a driving gear arranged at the locking bolt, and a tooth bar being arrange at the tripper push rod and being engaged with the drive gear.
Description
technical field [0001] The invention relates to a caliper device, in particular to an insulating caliper. Background technique [0002] On-site survey work is the preparatory work for electric power repair construction. During the survey, it is necessary to clarify the wire type and specification of the line. The on-site survey work is only the preparatory work. It is impossible for the surveyors to climb the power pole to measure the wire type and specification after the power failure of the line. Judging the wire type and specification based on experience has a high error rate; or after returning to the office to check the data, the wire type and specification are determined, but due to the untimely update of the data or poor storage, there are many mistakes in the judgment of the wire type and specification. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an insulated caliper capable o...
