Abstract

The invention relates to a circulating concrete material and component impact tester which comprises a base, the base is connected with a top plate through supports, the middle of the bottom plate isin bolted connection with a driving hammer rod, the lower end of the driving hammer rod is fixedly connected with a driving hammer, an embedded magnetic ring is arranged in the driving hammer, and falling distance limiting plates are symmetrically arranged on the supports on the two sides of the driving hammer. The lower portion of the driving hammer rod is in sliding connection with a loading weight disc, a magnetic induction counter is arranged on the loading weight disc, the upper portion of the driving hammer rod is in sliding connection with a lifting platform, the lifting platform is driven by a lead screw lifting mechanism, hook pressing devices used for hooking the loading weight disc are fixedly connected to the two sides of the lifting platform respectively, and travel switches are arranged on the hook pressing devices. The outer side of the pressing hook device slides along the falling distance limiting plate, and the top of the falling distance limiting plate is in bolted connection with a falling distance limiting block. The device is high in simulation degree of the concrete member and the test block under the impact load effect, easy and convenient to operate, good in practicability and wide in application range, and the test period is shortened.

Description

technical field [0001] The invention relates to the field of mechanical performance research of concrete specimens under impact load, in particular to a circular concrete material and component impact tester. Background technique [0002] The existing concrete impact performance test loading device is complicated to operate, has a large volume, and is difficult to disassemble and assemble. The test cycle needs manual control, and the test cycle is long. The production cost of the equipment is high, and the test objects are mostly small concrete test blocks, which are single and cannot meet the diverse needs of the test. Therefore, there is a need for a device that is simple and convenient to assemble and disassemble, occupies a small space, is simple to operate and low in manufacturing cost, and can perform various tests. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a circulating concrete material and compon...
