Problems solved by technology

For example, it is necessary to lay a cable from point A to point B, and it needs to be bent several times in the middle, the line is complicated, and the length of the cable is not easy to measure
The ordinary measurement method can only be estimated and the error is large, and it cannot meet the needs of accurately measuring the meter of the secondary cable. It is easy to cause the situation that the secondary cable is too much or the length is not enough; and the end of the cable needs a special Tool to strip outer sheath

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 , 2 A cable rangefinder shown includes a distance measuring wheel 4 and a roller seat 2, the distance measuring wheel 4 rotates coaxially relative to the roller seat 2, a handle 6 is mounted on the roller seat 2, and the distance measuring wheel 4 There is a counter on it. Wherein, the counter is a mechanical counter, and the counter and the roller seat 2 are symmetrically arranged on both sides of the distance measuring wheel 4 .

[0018] In order to facilitate the observation of the measured data, an observation window 5 corresponding to the counter is provided on the side of the distance measuring wheel 4 to read the required cable length value.

[0019] At the same time, a cable through hole 7 matched with the outer circle of the cable is also provided on the roller seat 2, so that the roller seat 2 can ...

Abstract

The invention discloses a cable distance measuring instrument and belongs to the electric power construction appliance technical field. The cable distance measuring instrument includes a distance measuring wheel and a rolling wheel seat; the distance measuring wheel rotates in the rolling wheel seat; the rolling wheel seat is provided with a handle; and the rolling wheel is provided with a counter. The distance measuring wheel rolls along the laying direction of a cable, so that the numerical value of the length of the required cable can be detected through the counter. Compared with an original cable estimation mode, the cable distance measuring instrument can assist in decreasing cable length errors and greatly improving cable measurement accuracy. The cable distance measuring instrument of the invention has the advantages of simple structure and convenient operation. With the cable distance measuring instrument adopted, the accuracy of secondary cable measurement can be improved, and cable laying construction can be facilitated.

Description

technical field [0001] The invention relates to the technical field of electric power construction tools, in particular to a cable range finder. Background technique [0002] At this stage, a large number of secondary cables need to be laid during the infrastructure construction and transformation of substations. For example, a cable needs to be laid from point A to point B, and it needs to be bent several times in the middle, the line is complicated, and the length of the cable is difficult to measure. The ordinary measurement method can only be estimated and the error is large, and it cannot meet the demand for accurate measurement of the meter of the secondary cable. It is easy to cause the secondary cable to be too much or the length is not enough; and the cable end needs a special The tool strips the outer sheath. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cable range finder with simple structure an...
