Description
Technical field
The utility model relates to the tamping machine power-lifter, relates in particular to the dynamic compaction machinery lifting appliance.
Background technology
In the building construction process, but when natural ground can not satisfy the building of design to the requiring of the advantage of ground, stability and distortion, usually all need ground is carried out consolidation process, changing the engineering property of ground soil property, and then satisfy the designing requirement of construction work.In the processing of carrying out the building operations ground, the most frequently used foundation reinforcement method should belong to dynamic compaction, and dynamic compaction machinery is being brought into play extremely important effect as a kind of first-selected plant equipment of implementing the foundation dynamic consolidation processing in the process that ground is processed.Common dynamic compaction machinery includes fuselage, hammer ram and tripping gear, wherein, tripping gear is connected by the suspension hook of dynamic compaction machinery, usually the weight of dynamic compaction machinery hammer ram is larger, generally weigh several tons even weigh tens tons, carry out ground treatment construction when doing at dynamic compaction machinery, make tripping gear hook hammer ram, then start dynamic compaction machinery, according to the different requirements of ramming ability, hammer ram is hung and is raised to several meters to tens meters height under the effect of dynamic compaction machinery, tripping gear and hammer ram is separated, at this moment, hammer ram will and collide with ground with freely falling body form whereabouts, can produce very large impact energy in the process of collision, impact capacity can produce corresponding profit ripple and dynamic stress on the ground, under the repeated action of stress wave and dynamic stress, loose soft ground soil property will obtain solidifying, its supporting capacity can be improved, and the soil density homogenizing of ground, and sedimentation phenomenon reduces.Although carrying out the processing of building lot, dynamic compaction machinery has obvious advantage, but because the own wt of hammer ram is large, in the process that hammer ram promotes, the phenomenon because the increasing of the weight of dynamic compaction machinery fore-body, dynamic compaction machinery fuselage generally can be leaned forward is if misoperation can be caused danger, especially in moment that tripping gear and hammer ram are separated, because the anterior weight of dynamic compaction machinery fuselage reduces suddenly, be easy to cause the dynamic compaction machinery fuselage to produce very large rocking, serious also be easy to cause equipment breakdown.
