Detachable multifunctional drop hammer impact test device

Abstract

The invention discloses a detachable multifunctional drop hammer impact test device, which is arranged on a reaction wall and a reaction bearing platform which are perpendicular to each other, and comprises an impact hammer, a rigid guide rod, a detacher, a fixed bracket, a first bracket, a second bracket and a structural test piece, the fixed bracket, the first bracket and the second bracket are sequentially fixed on a reaction wall from top to bottom; the upper and lower ends of the rigid guide rod are fixedly connected with the first bracket and the second bracket through bolts respectively; the impact hammer comprises a balance weight and an impact head arranged below the balance weight. The impact hammer is suspended right above the structural test piece and can vertically slide along the rigid guide rod; the lower end of the detacher is connected with the impact hammer, and the upper end of the detacher is connected with a winch arranged on the fixed support through a sling. The device is low in cost, is suitable for impact tests of most components such as beams, plates and columns in engineering structures, can be conveniently mounted and dismounted, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of impact test equipment for civil engineering structural components, in particular to a detachable multifunctional drop weight impact test device. Background technique [0002] In recent years, it is not uncommon for engineering structures to suffer accidental impact accidents. The effect of impact load on structures has been paid more and more attention in protection engineering, structural engineering and even national defense engineering. The impact resistance of structural components has become an important content in the field of engineering disaster prevention and mitigation. Due to the particularity of the impact load and the complexity of the dynamic response of the structure, it is often necessary to simulate the impact with the help of test equipment. [0003] The existing drop weight impact test device mainly includes steel structure tower, guide rail, impact hammer and other components. Steel t...

AI Technical Summary

Problems solved by technology

Steel towers often need to occupy a large test site, which also limits the type and size of structural test pieces

At the same time, the whole set of test equipment is complicated to manufacture and expensive

Due to the limitations of test sites and funds, there are fewer test devices of this type, which also brings inconvenience to the development of impact tests of engineering structural components.
