Buffering oil cylinder of dynamic compaction machine and installation structure thereof

Abstract

The invention discloses a buffering oil cylinder of a dynamic compaction machine. The buffering oil cylinder of the dynamic compaction machine comprises a cylinder body (5), wherein an outer piston (8) and an inner piston (3) are arranged inside the cylinder body (5), the outer piston (8) forms a rod cavity (6) and a rod-less cavity (9) inside the cylinder body (5), a damping hole (7) which penetrates through the rod cavity (6) and the rod-less cavity (9) is formed in the outer piston (8), the rod cavity (6) and the rod-less cavity (9) are filled with hydraulic oil (2), the outer piston (8) is connected with a piston rod (1), a spring (4) is arranged between the inner piston (3) and the cylinder body (5), and the cylinder body (5) is provided with an exhaust vent (10) which is communicated with the inner cavity of the spring (4). The buffering oil cylinder of the dynamic compaction machine achieves the effect of greatly consuming counter force of a pounder through a buffer spring and flow of the hydraulic oil in different cavities, and accordingly greatly reduces fatigue damage of the counter force of the pounder to rigid bodies such as a girder and a machine body platform, reduces shaking of a complete machine, especially of the girder, and improves overall stability and security.

Description

technical field [0001] The invention relates to a buffer oil cylinder, in particular to a buffer oil cylinder of a dynamic compaction machine, [0002] The invention also relates to the installation structure of the buffer oil cylinder of the dynamic compaction machine. Background technique [0003] According to the characteristics of dynamic tamping construction, when the tamper is released, the reaction force it produces on the components of the dynamic tamping mechanism is a major test for the life, stability and safety of the professional dynamic tamping machine. At present, most of the traditional dynamic tamping machines use springs as buffer devices, which have the disadvantages of more vibrations of components during buffering, long stabilization time, and low fatigue life of components. Therefore, the structure is improved so that when the rammer is released, The buffer device can quickly and effectively absorb the strong vibration energy of the component and quick...
