Portable lever puller for high-density electrical prospecting electrode pins

Abstract

The application discloses a portable lever pulling-out device for electrode nail of high-density electrical exploration, and relates to the technical field of geological exploration equipment. The device comprises a supporting module, a lever pivot module, a flexible steel wire rope and a self-tight pulling-out assembly. The supporting module comprises a base and a supporting column; the lever pivot module comprises a front force arm and an operating handle, which are coaxially hinged to the top end of the supporting column; the upper end of the flexible steel wire rope is connected to the front end of the front force arm, and the lower end is connected to the top of the pulling-out device shell. The pulling-out device shell is internally provided with an internal taper surface with a small upper part and a large lower part, a compression spring is arranged above the internal taper surface, the compression spring transmits a pushing force to a synchronous retaining ring through a pressure bearing gasket and a central fastening assembly; a plurality of wedges are hung through a circumferential array of wedge hinged shafts below the synchronous retaining ring, the outer wall of the wedges is slidably attached to the internal taper surface, and the inner wall of the wedges is provided with anti-skid teeth. The application realizes labor-saving pulling-out by using the lever principle, can keep vertical force application to avoid bending of the electrode nail, and has high portability and terrain adaptability.
