Embodiment Construction
[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0026] As a first aspect of the present invention, an anti-roller damping system is provided. Such as figure 1 and figure 2 As shown, the anti-rolling damping system includes an oil cylinder 10, a first cavity communication oil passage 20, a second cavity communication oil passage 30, and a damping oil passage 40. The oil cylinder 10 includes a first piston and has a first piston 14 interconnected Isolated first cavity 11 and second cavity 12; the first end of the first cavity communicating with the oil passage 20 communicates with the first cavity 11; the second cavity communicates with the first end of the oil passage 30 and the second cavity Body 12 communicates; the second end of the first cavity communication oil passage 20 and the second en...

The invention provides an anti-back-tipping damping system and a dynamic compaction machine. The anti-back-tipping damping system comprises an oil cylinder, a first cavity communication oil path, a second cavity communication oil path and a damping oil path. The oil cylinder comprises a first piston, a first cavity and a second cavity, wherein the first cavity and the second cavity can be isolated through the first piston. The first end of the first cavity communication oil path is communicated with the first cavity, and the first end of the second cavity communication oil path is communicated with the second cavity; and the second end of the first cavity communication oil path and the second end of the second cavity communication oil path are correspondingly communicated with two ends of the damping oil path in a one-to-one manner. The hydraulic damping manner is adopted by the anti-back-tipping damping system for damping, and the damping effect is ensured; the anti-back-tipping damping system can meet the different damping requirement of engineering mechanical equipment; and due to the fact that the first cavity and the second cavity of the oil cylinder are communicated through the damping oil path, oil pressure in the first cavity and oil pressure in the second cavity of the oil cylinder can be balanced, so that the damping function is achieved.
Description
technical field [0001] The invention relates to the field of construction machinery, and more specifically, to an anti-backward shock absorption system and a dynamic compaction machine. Background technique [0002] Construction machinery and equipment (such as dynamic compaction machines) often need to be equipped with an anti-backward shock absorption system to reduce the vibration amplitude and frequency of the equipment and ensure the working stability and reliability of the equipment. [0003] Take the dynamic tamping machine as an example. When the dynamic tamping machine performs tamping operations in a decoupling manner, the rammer falls freely after decoupling. At the moment of decoupling, the load released by the rammer will cause a strong impact on the boom, which will seriously damage the boom. The service life of the system and the stability and safety of the vehicle. [0004] At present, the anti-rear damping system is mostly a mechanical spring damping system...
