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

The invention discloses a service-life early-warning method of a dynamic consolidation machine. The service-life early-warning method includes the steps of detecting a one-time damage evaluation parameter value of a cantilever crane by ith-time impact, adding the one-time damage evaluation parameter value and a current total damage evaluation parameter value, enabling the value obtained through adding to serve as a new current total damage evaluation parameter value, comparing the new current total damage evaluation parameter value with a preset damage evaluation parameter threshold value, and giving a warning when the new current total damage evaluation parameter value is larger than or equal to the damage evaluation parameter threshold value. The invention further discloses a service-life early-warning system and the dynamic consolidation machine. According to the service-life early-warning method, the damage evaluation parameter value of the cantilever crane is detected and evaluated, and the warning is given when the current total damage evaluation parameter value is larger than or equal to the damage evaluation parameter threshold value, in this way, the service life of the cantilever crane can be monitored and early warned according to the practical work conditions of the cantilever crane, accidents caused by the phenomena such as cracking of the cantilever crane in the work process are avoided, and the safety performance of the dynamic consolidation machine is improved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a life warning method for a dynamic compaction machine, a life warning system and a dynamic compaction machine including the life warning system. 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 cran...
