Problems solved by technology
The long-term operation of the reel cable in the occasion of high tensile force, torsion, and back-and-forth friction dragging makes it difficult to measure and evaluate the service life of the cable. Knowing the design service life of this type of cable is the most urgent concern of port equipment manufacturers and customers question

Abstract
The invention discloses a testing device for testing mechanical properties of cables, comprising: a base, a support column and a first coiling block and a second coiling block for winding cables. A guide wheel can rotate around an axis thereof. A first support arm and a second support arm are respectively provided with a first gap and a second gap for embedding the cables. The front and back sides of the upper end face of the support column are respectively provided with a front baffle plate and a back baffle plate. The opposite faces of the front baffle plate and the back baffle plate are provided with guide grooves along the direction of the support column. A tension guide wheel seat is between the front baffle plate and the back baffle plate. Projection blocks and corresponding guide grooves are arranged at the outer side of the tension guide wheel seat and between the front baffle plate and the back baffle plate. The tension guide wheel seat can move forwards along the guide groove direction. Both ends of a tension guide wheel are mounted between the front end face and the back end face of the tension guide wheel seat by a first bearing. The lower end face of the tension guide wheel seat is connected with a cylinder. The testing device of the invention can detect tensile strength, torsion performance and life circumstances of the cables in a set environment, is beneficial to tide cables in a plane and buffer additional tension, and further improves the testing accuracy.
Description
technical field [0001] The invention relates to a test device for electric cables, in particular to a test device for detecting the mechanical properties of cables. Background technique [0002] With the continuous development of China's economy, the scale and total throughput of China's ports have ranked first in the world. In the future, the construction of special container ports will be the focus of port construction. The rapid development of ports will increase the demand for port machinery cables. [0003] The surrounding environment of the port is harsh. The equipment and cables used in the port must meet chemical damage such as corrosion resistance, acid resistance, alkali resistance, and smoke resistance, as well as mechanical properties such as wear resistance, torsion resistance, and tensile resistance. The reel cable is the most important type of port machinery cable, which has the characteristics of large demand, wide range of use, and high technical integration...
