Abstract
The utility model relates to a kind of light-duty pile press.For solving existing static pressure type pile driver from great problem, it comprises that a lower end relies on the ground overhead lever of going up top power hydraulic jack and its driving by support, and the other end of this lever is used to export downforce.Therefore, it has, and noise is low, and volume is little, in light weight, easy to use, does not fetch earth, not muck haulage, does not need to look for local advantage of falling soil and cost saving.
Description
Technical field
The utility model relates to pile driver, particularly relates to a kind of light-duty pile press.
Background technology
Existing static pressure type pile driver all is a large amount of balance weight body of adapted, leans on the gravity of balance weight body that stake is pressed in the ground.It has the advantage of noise-less pollution.But because it, also has the defective that shifts the building site difficulty simultaneously from great.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of little light-duty pile press of conducting oneself with dignity is provided.
For achieving the above object, the light-duty pile press of the utility model comprises that a lower end relies on the ground overhead lever of going up top power hydraulic jack and its driving by support, and the other end of this lever is used to export downforce.So the bigger balance weight body of deadweight has been omitted in design, therefore, has the little advantage of deadweight.
As optimization, the other end of lever also further is connected with the press-down type hydraulic jack, and the lower end of press-down type hydraulic jack is used to export downforce, and the oil pressure of two hydraulic jacks is identical, and the work plane of last topped hydraulic oil cylinder is greater than the work plane of press-down type hydraulic jack.So design has and presses down the big advantage of stroke.
As optimization, it is by four unidirectional commutation, oily obstructed power oils of logical control of cutting down; Control oil, the hydraulic principle of logical power oil realizes commutating, and four unidirectional cuts down to be cut down by four electromagnetic switch and control, and the logical control of energising oil, obstructed power oil, no power power oil pass through voluntarily, and four electromagnetic valves intersect switches on; 1DT, the 3DT logical power oil of A mouth of switching on is simultaneously built and is pressed the oil return of B mouth, and the piling oil cylinder presses down, stake is pressed in the soil, and back to the end, 2DT, 4DT energising, the logical power oil of B mouth is built and is pressed the oil return of A mouth, and the piling oil cylinder promotes back original position with core Tong.
Therefore, it has, and noise is low, and volume is little, in light weight, easy to use, does not fetch earth, not muck haulage, does not need to look for local advantage of falling soil and cost saving.
