Description

Technical Field

[0001] The invention relates to the technical field of impact test devices, in particular to an intelligent bidirectional impact testing machine. Background Art

[0002] Impact table experiments are of great significance for simulating collisions and falls of components. There are mainly drop hammer impact, pendulum impact, etc., among which the research on pendulum impact is relatively less. The pendulum impact table occupies a small vertical space, which is conducive to being placed in a laboratory with a small vertical space. There are basically no large-scale pendulum impact racks available, only small pendulum impact tables, whose functions are too monotonous, and the size of the test pieces that can be impacted is too small, and impact tests on large structures or components cannot be carried out. Most of the impact racks on the market are separate vertical or horizontal impact racks, which cannot perform vertical and horizontal impacts on components at the same time. Moreover, although the existing pendulum impact can perform multi-point impacts, it has no energy storage device, so the impact energy is small and cannot meet the requirements of the impact test well.

[0003] The pendulum impact tester is a fully automatic instrument for measuring the performance of metal materials in resisting impact under dynamic load, so as to judge the quality condition of the material under dynamic load. The existing pendulum impact tester cannot fully meet the needs of impact experiments in different fields, such as some large components that need impact. The main reason for this phenomenon is that the impact energy of the pendulum impact tester is smaller than that of the drop hammer impact tester. Therefore, there is no in-depth research and development of large pendulum impact testers. However, compared with this traditional concept, the large pendulum impact tester still has its own original advantages. The space it occupies in the vertical direction is much smaller than that of the drop hammer impact tester, which is friendly to some laboratories with insufficient vertical space. In terms of impact energy, it can provide support for the impact force by increasing the mass of the hammer head, the lifting angle, and the reverse instantaneous drive at the motor. For example, the publication number CN115127937A discloses a pendulum impact tester, which cannot impact in both directions at the same time, and cannot test the impact resistance of large metal components and non-metallic components. When large components need to be subjected to bidirectional impact, some structures cannot complete the impact test by simply adjusting the impact position. For example, concrete components have special material properties (brittleness, anisotropy, etc.). These will result in the destruction of their integrity and normal stress conditions by simply adjusting the component position. Summary of the invention

Inside the steel column 2, a first vertical guide rail 4 and a second vertical guide rail 5 are arranged in parallel, and the first vertical guide rail 4 is arranged on both sides of the second vertical guide rail 5. The two ends of the steel beam 3 are connected to the first lifting mechanism 6 through the first vertical guide rail 4, and the middle part of the steel beam 3 is connected to the second lifting mechanism 8 through the second vertical guide rail 5.

[0018] like Figures 2 to 3As shown, the first lifting mechanism 6 includes a first lifting motor 61 and a first linkage beam 62. The first lifting motor 61 is fixed to the end of the steel beam 3 through a first fixing member 63. The first linkage beam 62 is symmetrically arranged and parallel to the steel beam 3. Both ends of the first linkage beam 62 are arranged inside the first vertical guide rail 4. The first lifting motor 61 and the first linkage beam 62 are connected by a steel cable. The first lifting mechanism 6 is connected to a transverse impact mechanism 7 below. The transverse impact mechanism 7 includes an energy storage motor 71, a hammer handle 72, and a hammer head 73. The energy storage motor 71 is fixed to the upper surface of the first linkage beam 62 through a first connecting member 74. The upper end of the hammer handle 72 is connected to the energy storage motor 71, and the lower end of the hammer handle 72 is detachably connected to the hammer head 73.

[0019] like Figure 4 As shown, the second lifting mechanism 8 includes a second lifting motor 81 and a second linkage beam 82. The second lifting motor 81 is fixed to the middle of the beam through a second fixing member 83. The second linkage beam 82 is also symmetrically arranged and parallel to the steel beam 3.
