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.

The invention relates to the technical field of maintenance of ultra/extra-high voltage equipment, and discloses an insulator zero value intelligent detection auxiliary device. The device comprises afixing base, a containing groove base used for containing an insulator operating rod in a sliding mode is arranged at the top of the fixing base, a rotating base used for rotating the containing groove base is arranged between the containing groove base and the fixing base, a plurality of telescopic supporting rods are hinged to the bottom of the fixing base, and tower material clamps are hinged to the ends, away from the fixing base, of the telescopic supporting rods. The containing groove base is provided with a sliding channel for the insulator operating rod to pass through, and a rotatingwheel is installed in the sliding channel. The problem that the operating rod shakes due to the change of the operating length of the insulating operating rod is solved, so that ground potential operators are helped to operate and control the insulating operating rod efficiently, stably, safely and reliably, and the insulator detection efficiency and the data accuracy are improved.

The invention discloses a semiconductor packaging fixing device which comprises a base and a support, a cushion block is arranged on the base, a pressing plate is arranged on the support, and the pressing plate and the base are fixed so that the support and the cushion block can be fixedly connected. According to the semiconductor packaging fixing device provided by the invention, the cushion block and the pressing plate are designed, and a plurality of fixing structures are arranged on the cushion block and the pressing plate, so that the bracket is more firmly fixed, the phenomenon that a wire arc is crushed by the pressing plate due to improper manual placement of the bracket is avoided, the pressing effect of the bracket in the push-pull force process is improved, and the data accuracy is ensured.
