Drilling tool and method for constructing borehole in ground
The invention relates to a drilling tool for constructing a drill hole in a ground, comprising a rotatably drivable base body, a removal device at a lower end of the base body for removing ground material, and at least one adjustable removal element, the removal element can be adjusted between a radially inner retracted position and a radially outer widened position, in which the removal element protrudes radially outward with respect to the base body for widening the bore diameter. According to the invention, in order to adjust the removal element, an adjustment mechanism is provided with a rotating part which can be rotated on the base body about a drilling axis between a first rotational position and a second rotational position, and the at least one removal element is arranged on a pivot arm, the pivot arm is pivotable relative to the base body between a first pivot position, in which the at least one removal element is in its retracted position, and a second pivot position, in which the at least one removal element is in its widened position, in which the at least one removal element is in its widened position. An actuating projection is provided on the rotating part and/or on the at least one pivot arm, by means of which a rotational movement of the rotating part can be converted into a pivoting movement of the at least one pivot arm.
本发明涉及一种用于在土地中构建钻孔的钻孔工具，所述钻孔工具具有能被可转动地驱动的基体、在所述基体的下端部处的用于去除土地材料的去除装置和能调节的至少一个去除元件，所述去除元件能够在沿径向处于内部的收回位置和沿径向处于外部的扩宽位置之间调节，在所述扩宽位置中，所述去除元件沿径向向外相对于所述基体突出，以用于扩宽钻孔直径。根据本发明设置成，为了调节所述去除元件，设置有带有转动部件的调节机构，所述转动部件在所述基体处能够围绕钻孔轴线在第一转动位置和第二转动位置之间转动，所述至少一个去除元件布置在枢转臂处，所述枢转臂能相对于所述基体在第一枢转位置和第二枢转位置之间枢转，在所述第一枢转位置中，所述至少一个去除元件处于其收回位置中，在所述第二转动位置中，所述至少一个去除元件处于其扩宽位置中，并且在所述转动部件处和/或在所述至少一个枢转臂处设置有操纵凸起部，通过所述操纵凸起部能将所述转动部件的转动运动转换成所述至少一个枢转臂的枢转运动。
