Description

Technical Field

[0001] The utility model relates to the technical field of cable stretch detection, in particular to a power cable stretch detection device. Background Art

[0002] During the tensile process, after the material passes through the yield stage and enters the strengthening stage, the transverse cross-sectional dimensions are significantly reduced. The maximum force it bears when it is pulled apart is divided by the original cross-sectional area of ​​the specimen. The stress is called tensile strength or strength limit. Most cable tensile strength testing devices on the market cannot measure the elongation of the cable in a timely manner, resulting in a certain deviation in the elongation and a large error in the test results.

[0003] In the Chinese utility model patent application disclosure specification CN215525298U, a power cable tensile strength detection device is disclosed, comprising a bottom plate, two symmetrically arranged fixed plates are fixedly connected to the bottom plate, a threaded rod is rotatably inserted between the two fixed plates, a handle is fixedly connected to the other end of the threaded rod, a mobile frame is threadedly arranged on the threaded rod, a mounting frame is arranged on the mobile frame, a sliding opening is opened on the side wall of the mounting frame, a digital push-pull force gauge is fixedly installed on the mounting frame by bolts, and a stud is fixedly connected to the side wall of the digital push-pull force gauge. The power cable tensile strength detection device is provided with a mounting frame, a sliding opening and a nut. When the position of the mounting frame needs to be adjusted, the mounting frame is pushed to slide on the mobile frame, so that the stud slides inside the sliding opening, and then the nut is screwed on so that one end of the nut is against the mobile frame, so that the position adjustment of the digital push-pull force gauge is realized, the pulling direction is changed, and comprehensive data is obtained. However, the device detects a relatively small number of cables at the same time, and the efficiency is not high. For this reason, we propose a power cable tensile detection device.
