Picker and method for picking targeted object

Abstract

The invention relates to the field of machinery, in particular to a picker and a method for picking a targeted object. A self-locking function is produced due to the structure of the picker, and the phenomenon that pliers arms of the picker are loosened because the targeted object is too heavy is avoided, so the picker can pick the object at a long distance reliably when power is not sufficient. The picker comprises a guide device, a pliers seat, a lifting and pulling piece, and a clamping device; the guide device comprises a guide column and a guide plate; the lower end of the guide column is fixedly connected with the guide plate; the pliers seat is provided with a through hole or a notch which is penetrated from the upper part of the pliers seat to the lower part of the pliers seat, so the guide column can slidably pass through the through hole or the notch; the lifting and pulling piece comprises at least one lifting and pulling rope which is provided with a free end and a connection end which is connected with the pliers seat; the clamping device comprises at least two pliers arms; the upper end of each pliers arm is pivoted with the pliers seat; the pliers arms can slidably pass through a guide hole of a guide plate respectively to ensure that the lower end of each pliers arm is selectively unfolded or folded relative to a central shaft of the picker; and each pliers arm is arch-shaped, and the opening of the arch faces the central shaft of the picker.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a picker and a method for picking up a target item. Background technique [0002] In the prior art, the existing pick-up life-saving products can only be picked up at a long distance under powered conditions, such as in wells, but in areas lacking power supply (such as areas lacking electricity supply), they will not be able to pick up long-distance target items. Picking up and salvaging limits the use distance of picking up or salvaging, which is not conducive to instant picking up or salvaging. Contents of the invention [0003] The invention provides a picker and a method for picking up a target item, which can reliably pick up from a long distance when the power is insufficient or there is no power condition (such as lack of power supply). [0004] The invention provides a pickup, characterized in that it comprises: [0005] A guiding device, which includes a guide post and a guide...
