The invention provides a load impact experimental system used for measuring the impact resistance of a rod-shaped connection body under the tension load. The load impact experimental system comprises a top beam, a base, stand columns, a hanging device, a tensioning and pre-tightening device, a load-bearing tray and a heavy hammer. The stand columns are arranged between the top beam and the base and used for supporting the top beam and the base. The hanging device is arranged on the top beam and used for fixing one end of the rod-shaped connection body. The tensioning and pre-tightening device is arranged on the base and used for fixing the other end of the rod-shaped connection body and providing tension loads for the rod-shaped connection body. The load-bearing tray is used for providing a force point for the rod-shaped connection body. The heavy hammer is used for exerting impact force on the load-bearing tray. When the load impact experiment is conducted through the load impact experimental system, the load impact experimental system more conforms to the practical rule of field use, the impact resistance of the rod-shaped connection body under the composite stress is truly measured, and true and accurate reference data are provided for field construction.
Description
technical field [0001] The invention relates to the technical field of testing the bearing capacity of a rod body or a rope body subjected to a tensile load when subjected to an instantaneous impact, and specifically refers to a load impact test system and a use method thereof. Background technique [0002] The load impact test system is a new test method at home and abroad, and it is in line with the test performance of mine site impact products. [0003] The load impact test system is to add loading equipment to the original impact test system, so that the impact test conforms to the actual situation on site. When the anchor rod or anchor cable support product (rod body test product) on the mine site is subjected to impact load, it is not to the existing impact test, and the rod body test product such as anchor rod or anchor cable is empty load (that is, it is not subjected to tensile load) , Generally, rod body test products such as anchor rods or anchor cables on site a...
