[0002] In the overhead power line installation project, due to differences in installation standards in different areas, the wire diameters of the cables actually used in each area are different. In the subsequent unified management, in order to ensure power safety, it is necessary to measure and record the wire diameters of the overhead conductors in all areas.

[0003] Traditional wire diameter measurement solutions mostly involve manually climbing onto the wire rack, getting close to the cable, and then using handheld tools to measure. This has the problems of difficult operation, low measurement efficiency and danger. There are also long-rod tools for ground-based measurement, which are connected by inner and outer tubes. The inner and outer tubes are respectively connected to the clamp seat and the clamp plate at the end. The clamp plate is moved by moving the inner tube, so that the clamp plate and the clamp seat clamp the cable to measure the wire diameter. However, in actual operation, the cable is usually high, resulting in a long measuring tool. If an integrated type is used, it is inconvenient to carry. If a spliced ​​type is used, the inner and outer tubes need to be installed separately, resulting in the entire measuring tool being very inconvenient to use. For this purpose, a rapid diameter measurement tool for overhead conductors is provided to solve the above problems. Summary of the invention

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The embodiment of the present application solves the problem that the existing overhead line diameter measuring tools are inconvenient to carry and use by providing an overhead line wire diameter rapid measuring tool.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The embodiment of the invention discloses a tool for quickly measuring the diameter of an overhead conductor.

[0027] According to the attached Figure 1-5 As shown, it includes a measuring clamp 1, an operating rod 2 and an operating observation member 3. The measuring clamp 1 and the operating observation member 3 are respectively arranged at both ends of the operating rod 2. The measuring clamp 1 is provided with a movable clamping port for clamping the cable, and the operating observation member 3 is provided with an observation groove 35 corresponding to the movable clamping port. The operating rod 2 can drive the movable clamping port to expand and contract to clamp the cable, and the observation groove 35 changes synchronously with the expansion and contraction of the movable clamping port to present the outer diameter of the cable.

[0028] Hang the clamping seat 11 on the outer surface of the cable, and then twist the operating rod 2 to make the clamping seat 11 rotate. At this time, the wire clamping part 113 is against the side of the cable, so that the clamping seat 11 cannot continue to rotate. At this time, one hand holds the positioning handle 31, and the other hand rotates the operating rod 2. At this time, the splicing rod 21 spirals upward, thereby driving the clamping plate 121 to slide upward, and finally the clamping plate 121 and the clamping seat 11 complete the clamping of the cable. At this time, the position of the bottom end of the splicing rod 21 at the observation scale 34 is observed through the observation groove 35, thereby completing the wire diameter measurement.

[0029] The operating rod 2 includes a splicing rod 21 and an upper threaded column 22 fixedly arranged at the top of the splicing rod 21. A threaded seat 112 is integrally formed at the bottom end of the clamping seat 11. The upper threaded column 22 is threadedly connected to the threaded seat 112. The sliding clamping member 12 includes a clamping plate 121 and a rotating seat 122 integrally formed at the bottom of the clamping plate 121. The top of the upper threaded column 22 is rotatably connected to the rotating seat 122. When the operating rod 2 rotates, the upper threaded column 22 spirally moves upward in the threaded seat 112, and the upper threaded column 22 rotates with the rotating seat 122, thereby pushing the clamping plate 121 to slide upward.

[0030] The measuring clamp 1 includes a clamping seat 11 and a sliding clamp 12 slidably arranged on the inner side of the clamping seat 11. One side of the sliding clamp 12 forms a movable clamping opening with the inner side of the clamping seat 11. One end of the operating rod 2 passes through the inner side of the clamping seat 11 and is connected to the sliding clamp 12.

[0031] The clamping seat 11 is L-shaped, and a wire clamping portion 113 for clamping the cable is provided at the end of the clamping seat 11. The wire clamping portion 113 is located on one side of the movable clamping port, so that after the clamping seat 11 is hung on the outer surface of the cable, the wire clamping portion 113 is abutted against the outer wall of the cable by twisting the clamping seat 11, so that the clamping seat 11 cannot rotate with the operating rod 2, and plays an automatic limit role. When in use, there is no need to use the inner and outer tubes to fix the clamping plate 121 and the clamping seat 11 respectively, which saves more materials and is more convenient to install and use. .

[0032] The operating observation part 3 includes a positioning handle 31 and a control tube 33 fixedly arranged at the upper end of the positioning handle 31. The operating rod 2 is threadedly connected to the positioning handle 31. The operating rod 2 movably passes through the control tube 33. The observation groove 35 is opened on the side wall of the control tube 33. By rotating the splicing rod 21, the upper threaded column 22 spirally moves upward in the threaded seat 112, and the lower threaded tube 23 spirally moves upward inside the driving stud 32, so that the relative displacement of the upper end clamp 121 in the clamping seat 11 is reflected by the displacement of the bottom end of the splicing rod 21 and the observation scale 34, thereby realizing the wire diameter measurement.

[0033] The operating rod 2 includes a splicing rod 21 and an upper threaded column 22 fixedly arranged at the top of the splicing rod 21 . A threaded seat 112 is integrally formed at the bottom end of the clamping seat 11 . The upper threaded column 22 is threadedly connected in the threaded seat 112 .

[0034] The sliding wire clamp 12 includes a clamp 121 and a rotating seat 122 integrally formed at the bottom of the clamp 121. The top end of the upper threaded column 22 is rotatably connected to the rotating seat 122. A limiting portion 123 is provided on one side of the clamp 121. The limiting portion 123 is slidably connected to the side of the clamping seat 11. A reference scale 114 is provided on the outer side of the clamping seat 11.

[0035] A lower threaded tube 23 is fixedly mounted on the inner bottom of the splicing rod 21 , and a driving stud 32 is fixedly mounted on the top of the positioning handle 31 . The driving stud 32 is threadedly connected in the lower threaded tube 23 .

[0036] An observation groove 35 penetrating to the inner wall is formed on the outer surface of the control tube 33 , and an observation scale 34 is provided on one side of the observation groove 35 .

[0037] The splicing rod 21 is formed by connecting multiple groups of hollow tubes 211 end to end, and a connecting piece is installed between two adjacent groups of hollow tubes 211, so that the splicing rod 21 can be quickly assembled according to the required length when in use.

[0038] The connecting piece includes an external threaded kit 212 and an external threaded insert 213, which are respectively fixedly arranged in two opposite sets of hollow tubes 211, and are plugged into each other. The outer surfaces of the external threaded kit 212 and the external threaded insert 213 are threadedly connected with an internal threaded ring 214.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
