Detection device for filling degree of concrete of cast-in-place pile

The invention relates to the technical field of constructional engineering detection equipment, in particular to a cast-in-place pile concrete filling degree detection device which comprises a moving vehicle, a mechanical arm is fixedly mounted at the top end of the moving vehicle, a mounting assembly is fixedly mounted at one end of the mechanical arm, and a bearing assembly is inserted into the mounting assembly. A detection probe is arranged in the bearing assembly; through the mode that third springs are installed on the outer sides of second hinge rods, the situation that the cleaning brush is squeezed by the detection probe to be disengaged from the surface of the detection probe is avoided, and therefore the problem that the cleaning brush cannot clean the surface of the detection probe is avoided; and two groups of springs III always have a drawing force and an extrusion force, so that the attaching area of the cleaning brush and the surface of the detection probe is increased, the cleaning brush can
