Tension test device and tension test system

Abstract

The invention relates to a tension test device and a tension test system. In the tension test process, fixing structures are respectively arranged on a base at intervals; a stress tool, an assistor and a tension meter are connected between the two fixing structures; and after assembling, the assistor is used for applying a pulling force to the stressed tool. And when the reading on the tension meter reaches a predicted force, the stress tool is kept to be stressed for a preset duration;, and after the preset duration, the appearance change of the stress tool is observed and the current readingon the tension meter is read. Compared with traditional large-scale test equipment, the device can complete a tension test by adopting the fixing structures, the assistor and the tension meter, so that the structure of the tension test device is simplified, the occupied space of the device is reduced, and great convenience is brought to an operator to test a stress tool in time. Meanwhile, when the base is of a structure in a construction site, such as a steel rail, the tension test device can be erected in the construction site at any time through the fixing structures, so that an operator can carry out tension test operation at any time.

Description

technical field [0001] The invention relates to the technical field of tensile testing, in particular to a tensile testing device and a tensile testing system. Background technique [0002] Safety belts, wire ropes, wire tensioners and other force-bearing tools are necessary safety tools for high-altitude operations and disassembly operations. It is required to conduct inspections and random inspections every year to ensure that all force-bearing tools are in a qualified state, so as to ensure normal operation. and personal safety. When some stressed wires on the operation line have material performance degradation or failure, samples need to be taken for tensile test. However, grass-roots workers usually lack standardized test benches to operate and perform tensile tests, which is not conducive to the standardization of the tensile test operation process and the personal safety of operators. At the same time, professional testing institutions often use large-scale equipme...

However, grass-roots workers usually lack standardized test benches to operate and perform tensile tests, which is not conducive to the standardization of the tensile test operation process and the personal safety of operators.

At the same time, professional testing institutions often use large-scale equipment, which occupies a large area and is expensive, and cannot be universally configured, and it is not convenient to carry out tensile tests on force-bearing tools in a timely manner
