A cable toughness testing device

Abstract

This utility model discloses a cable toughness testing device, relating to the field of cable testing. It includes a testing platform with a support column mounted on its upper end. A limiting groove is formed at the inner end of the support column, and a clamping frame is installed at the inner end of the limiting groove. An internal screw is installed in the middle of the clamping frame. This utility model, through the testing platform, support column, limiting groove, clamping frame, internal screw, and bottom motor, allows the cable to pass through the annular opening formed between the support column and the clamping frame at the front end of the testing platform. The cable is then pulled to the annular opening formed between the support column and the clamping frame at the other end of the testing platform. The bottom motor rotates, causing the clamping frame to descend vertically within the limiting groove, thereby clamping and fixing the cable to the support column. The toothed arrangement of the support column and clamping frame effectively prevents the cable surface from being too smooth, thus improving the stability of the clamping device.

Description

Technical Field

[0001] This utility model relates to the field of cable testing, specifically a cable toughness testing device. Background Technology

[0002] Cables are typically made of several or groups of conductors twisted together, similar to a rope. Each group of conductors is insulated from each other and twisted around a central core. The entire cable is covered with a highly insulating outer layer. They are mainly used to transmit and distribute electrical energy or transmit electrical signals. During the production, transportation, installation, and use of cables, toughness is a key performance indicator, which directly affects the cable's service life, reliability, and applicable scenarios. In the latter half of the production process, a testing device is needed to test its toughness. Existing cable toughness testing devices suffer from insufficient clamping stability due to the smooth surface of the cable and poor testing efficiency. Therefore, a new cable toughness testing device is needed.

[0003] Existing cable toughness testing devices cannot effectively improve the stability of the device clamping and the efficiency of the device testing during operation. Therefore, there is an urgent need for a new cable toughness testing device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cable toughness testing device to solve the problems that existing cable toughness testing devices cannot effectively improve the stability of device clamping and the efficiency of device testing during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable toughness testing device, comprising a testing platform, a support column installed at the upper end of the testing platform, a limiting groove formed at the inner end of the support column, a clamping frame installed at the inner end of the limiting groove, an internal screw installed at the middle end of the clamping frame, and a bottom motor installed at the lower end of the internal screw.

[0006] The front end of the testing platform is equipped with a testing and observation instrument. A limit groove is formed at the upper end of the testing platform. A top plate is installed at the inner end of the limit groove. A hydraulic rod is installed at the lower end of the top plate.

[0007] Preferably, the clamping frame forms a sliding structure with the support column through a limiting groove, and the upper end of the support column is a slotted arc.

[0008] Preferably, the clamping frame is threadedly connected to the built-in screw, and the built-in screw forms a rotating structure with the testing table via a bottom-mounted motor.

[0009] Preferably, the clamping frame forms a lifting structure with the testing table via a built-in screw, and the clamping frame is symmetrically arranged with respect to the central axis of the testing table.

[0010] Preferably, the top plate is movably connected to the testing platform via a limiting groove, and the upper surface of the top plate is set in a semi-circular arc shape.

[0011] Preferably, the top plate forms a lifting structure with the testing platform via a hydraulic rod, and the top plate is positioned at the center of the testing platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a testing platform, support column, limiting groove, clamping frame, built-in screw and bottom motor to pass the cable through the annular opening formed between the support column and the clamping frame at the front end of the testing platform, and pull it to the annular opening formed between the support column and the clamping frame at the other end of the testing platform. The rotation of the bottom motor drives the clamping frame to descend vertically in the limiting groove, thereby clamping and fixing the cable to the support column. The toothed support column and clamping frame effectively prevent the cable surface from being too smooth and affecting the clamping effect, thus improving the stability of the device.

[0014] 2. This utility model uses a testing platform, a testing and observation instrument, a limiting groove, a top plate, and a hydraulic rod. The hydraulic rod drives the top plate to leave the limiting groove, pushing the middle position of the cable upwards and backwards, thereby subjecting the cable to multiple impacts to test its toughness. At the same time, the testing and observation instrument is used to observe the internal cable integrity, improving the efficiency of the device's testing. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figures 1-4 A cable toughness testing device includes a testing platform 1, a support column 2 mounted on the upper end of the testing platform 1, a limiting groove 3 formed at the inner end of the support column 2, a clamping frame 4 mounted at the inner end of the limiting groove 3, an internal screw 5 mounted in the middle of the clamping frame 4, and a bottom motor 6 mounted at the lower end of the internal screw 5. The clamping frame 4 and the support column 2 form a sliding structure through the limiting groove 3, and the upper end of the support column 2 is a slotted arc. The clamping frame 4 and the internal screw 5 are threadedly connected, and the internal screw 5 forms a rotating structure with the testing platform 1 through the bottom motor 6. The clamping frame 4 and the testing platform 1 form a sliding structure through the internal screw 5. The lifting structure, with the clamping frame 4 symmetrically arranged around the central axis of the testing platform 1, allows the cable to pass through the annular opening formed between the support column 2 at the front end of the testing platform 1 and the clamping frame 4. The cable is then pulled to the annular opening formed between the support column 2 and the clamping frame 4 at the other end of the testing platform 1. The rotation of the bottom motor 6 drives the clamping frame 4 to descend vertically within the limiting slide groove 3, thereby clamping and fixing the cable to the support column 2. The toothed arrangement of the support column 2 and the clamping frame 4 effectively prevents the cable surface from being too smooth, thus affecting the clamping effect and improving the stability of the device.

[0023] Please see Figures 1-4 A cable toughness testing device includes a testing platform 1 with a testing observation instrument 7 installed at the front end. A limiting groove 8 is formed at the upper end of the testing platform 1, and a top plate 9 is installed inside the limiting groove 8. A hydraulic rod 10 is installed at the lower end of the top plate 9. The top plate 9 is movably connected to the testing platform 1 through the limiting groove 8, and the upper surface of the top plate 9 is semi-circular. The top plate 9 and the testing platform 1 form a lifting structure through the hydraulic rod 10, and the top plate 9 is positioned at the center of the testing platform 1. The hydraulic rod 10 drives the top plate 9 to leave the limiting groove 8, pushing the middle part of the cable upwards and backwards, thereby subjecting the cable to multiple impacts to test its toughness. Simultaneously, the testing observation instrument 7 is used to observe the internal cable integrity, improving the efficiency of the device's testing.

[0024] Working principle: In use, the cable is first passed through the annular opening formed between the support column 2 and the clamping frame 4 at the front end of the testing platform 1, and then pulled to the annular opening formed between the support column 2 and the clamping frame 4 at the other end of the testing platform 1. The rotation of the bottom motor 6 causes the clamping frame 4 to descend vertically within the limiting groove 3, thereby clamping and fixing the cable to the support column 2. The toothed support column 2 and clamping frame 4 effectively prevent the cable surface from being too smooth, thus improving the clamping effect and enhancing the stability of the device. Then, the hydraulic rod 10 can drive the top plate 9 to leave the limiting groove 8, pushing the middle part of the cable upwards and back and forth, thereby subjecting the cable to multiple impacts to test its toughness. At the same time, the internal cable integrity is observed through the inspection and observation instrument 7, improving the efficiency of the device's inspection. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
