Pendulum assembly and pendulum impact test apparatus having the same

Abstract

The present invention provides a pendulum assembly and a pendulum impact test apparatus having the pendulum assembly. The pendulum assembly comprises a fixation bracket and a pendulum handle, wherein the pendulum handle is rotatably connected with the fixation bracket, and is provided with a pendulum. The pendulum assembly further comprises a hydraulic pressure oil cylinder assembly for driving the pendulum handle to swing, and a clutch arranged between the hydraulic pressure oil cylinder assembly and the pendulum handle, wherein the clutch is provided with a conjugation position for making the hydraulic pressure oil cylinder assembly push the pendulum handle and lifting the pendulum, and a separation position for making the pendulum handle freely swing so as to make the pendulum impact a test piece. According to the present invention, match of the hydraulic pressure oil cylinder assembly and the clutch is adopted to push the pendulum handle, such that the pendulum assembly structure is compact, and a vertical occupation space of a gantry can be effectively reduced; and the clutch is adopted to control combination and separation of the hydraulic pressure oil cylinder assembly and the pendulum handle, such that characteristics of simpleness, reliability, easy control and precision are provided, and complexity of the whole structure is effectively reduced.

Description

technical field [0001] The invention relates to the field of pendulum impact test devices, in particular to a pendulum component and a pendulum impact test device having the same. Background technique [0002] Earthmoving machinery may often be impacted by rocks, debris or other objects during construction, and the toughness of components may be significantly lower than that of static loads when subjected to high-speed impact loads, so it is necessary to carry out dynamic test verification , the dynamic test is to simulate the impact of the actual impact energy on the material or component to verify whether its toughness is qualified. [0003] At present, there are roughly two types of experimental devices, namely, the pendulum impact testing machine for the impact resistance of materials and the commercial vehicle impact test platform. The installation space and impact energy parameters of the former can only be impacted on specific material specimens. test; and the impact...
