Benefits of technology

This patented device helps detect changes over time caused by stress on an endless metal chain used in conveying systems such as cables or pulleys. Its technical benefits include improved precision and reliance when testing these materials under tension conditions compared to traditional methods like visual inspections alone.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the durability and reliance of steel cords that are commonly used in conveying machines such as conveyors or hoists due to their ability to carry heavy loads over longer periods without losing effectiveness during use. Additionally, there may be concerns about how well these connections can maintain their integrity when subjected to external forces like vibrations caused by machinery or sudden changes in temperature conditions.

Embodiment Construction

[0017] The specific implementation manner of the content of the invention will be described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the hardware device of the tensile test in the present invention is composed of a tensile testing machine 1 , an X-ray source 2 , an X-ray dynamic flat panel detector 3 and a joint sample 4 . The joint sample is fixed in the tensile testing device of the tensile testing machine 1, and the X-ray source 2 and the X-ray dynamic flat panel detector 3 are respectively installed on both sides of the surface area of ​​the joint sample, so that the X-ray source 2 can project On the surface of the joint sample 4, the X-ray dynamic flat panel detector 3 can collect the steel wire rope core image inside the joint sample 4. The X-ray dynamic flat panel detector 3 selects an area array dynamic imaging detector with a resolution of 1316×1312 and an imaging speed of not less than 10 frames per second to obtain high-

Abstract

The invention discloses an X-ray monitored steel wire rope core conveyor belt joint tensile test method to solve a problem of real-time monitoring of an internal state of a joint in a steel wire ropecore conveyor belt joint tensile test. The X-ray monitored steel wire rope core conveyor belt joint tensile test method adopts a method of combining the joint tensile test with an X-ray transmission dynamic area array imaging technology to realize dynamic monitoring of deformation of a steel wire rope core joint region, thereby successfully acquiring key experimental data such as real-time dynamicimages and elongation of the joint deformation. Through the joint tensile test method provided by the invention, data accuracy of a joint state obtained by the test can be greatly improved, and an effective experimental support is provided for research of the performance of the steel wire rope core conveyor belt joint.
