Description

Civil engineering piling machine
Technical field
The present invention relates to Architectural Equipment technical field, more particularly, to a kind of piling machine.
Background technology
With national economic development and the fast development of infrastructure, all kinds of buildings are constantly gushed out, regardless of whether construction scope Size and purposes, all inevitably need use pile in substantial amounts of building, if because large-scale ground building is wanted Build on the ground, ground will bear very big pressure, it is necessary that there is enough renitent intensity on ground, this is often It is difficult to accomplish.So the ground for bearing building must just be reinforced or improve ground bears mode, so just thinking Drive piles on ground, allow most of weight of building to pass to the very deep position of below ground by stake, because this position Ground it is more much bigger than ground ability to bear.And by pile building can be made more firm for aedicula.Each Class river both sides, construction of park, the occasions such as bridge formation of repairing the roads, it is also desirable to carry out piling work and reinforced or for viewing and admiring.Beat Stake is a kind of widely used civil construction mode, and people carry out engineering construction by the way of piling machine at present.Piling machine by Pile monkey, pile frame and auxiliary device etc. form, its main technical parameter is impact moiety by weight, impact kinetic energy and frequency of impact. Current piling machine specific aim is stronger, because without possessing the condition used under more scenes, i.e. applicability is not strong.Particularly with small-sized Civil construction, since the size, material and piling of pile require different, also differs widely the performance requirement of piling machine, Existing piling machine can not adjustment period technical parameter, cause a variety of machines of engineering construction needs, it is very cumbersome.
In piling machine apparatus field, people have carried out long-term and deep exploration, and the species of piling machinery is also enriched therewith, Chinese patent(Application number:201510465335.5)Disclose a kind of comprehensive piling machine, comprising piling platform, driven in translation structure, Piling cushion cap, lifting structure, rack body and construction passage.Upper frame body is equipped with rack body upper end, is set inside upper frame body Drilling rod is equipped with, upper frame body side surface is provided with piling hammer body, the advantage is that with two kinds of works of rotation piling and jump bit piling Industry mode and realizing laterally and longitudinally moves.But it does not solve piling machine frequency of impact and impact during piling The unalterable problem of kinetic energy, is only applicable in the matched piling work of pile intensity, it is impossible to realize a tractor serves several purposes.
The content of the invention
The technical problem to be solved in the present invention is existing piling machine frequency of impact and the unalterable problem of impact kinetic energy, Propose a kind of using the bent shaft-driven different pile intensity of adaptation that can adjust frequency of impact and impact kinetic energy, the soil of material Wood engineering piling machine.
