Problems solved by technology

When the rammer is raised to the rated height, the automatic uncoupling device controls the rammer to unhook, and the crane unloads the load instantly. Due to the elastic energy storage effect of itself and the wire rope, the jib of the crane vibrates violently and releases energy, resulting in the jib of the crane and the The relevant parts are impacted, which may cause premature damage to the relevant parts of the crane, or cause the jib to tip backwards, or even cause the jib to break in advance

Abstract

The invention discloses a back-tilting prevention device of a dynamic compactor. The back-tilting prevention device comprises a back-tilting prevention oil cylinder of which two ends are respectively connected to an arm support and a base of the dynamic compactor. Back-tilting of the arm support of the dynamic compactor is prevented through a hydraulic device. The invention also discloses a back-tilting prevention system of the dynamic compactor and the dynamic compactor. The rigidity of the back-tilting prevention device is controlled by controlling the pressure of a hydraulic oil path, so that the rigidity of a back-tilting oil cylinder is adjusted according to a specific working condition of the dynamic compactor; therefore, the back-tilting prevention device has different rigidities under different working conditions, a proper buffering effect is achieved, and the safety of the dynamic compactor is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an anti-backward device of a dynamic compaction machine, an anti-backward system and a dynamic compaction machine. Background technique [0002] The dynamic tamping machine is a kind of construction machinery equipment that uses lifting equipment to repeatedly lift the rammer to a certain height, and then uses automatic decoupling to release the load or free fall with the hammer to ram the foundation with strong impact energy and improve the strength of the foundation. . [0003] For dynamic compactors, sudden unloading is a normal and frequent working condition for dynamic compactors. Therefore, the boom of the dynamic compaction machine is often in a state of vibration due to the sudden unloading of this broadband excitation. [0004] At present, most domestic dynamic compaction construction equipment is modified on the basis of crawler cranes for small and medium tonnage...
