A split pin bending pliers

Abstract

The invention provides a split pin bending pliers, comprising: an upper pliers body and a lower pliers body hinged through a first rotating shaft, the upper pliers body is provided with a circular arc end for accommodating the split pin at the end away from the first rotating shaft The positioning groove of the lower caliper body is provided on the upper surface of the end portion away from the hinge shaft with a first action surface and a second action surface that intersect with each other, and the first action surface and the second action surface are respectively connected to the The first leg of the cotter pin is matched with the second leg; it also includes a trigger part for driving the lower clamp body to slide relative to the upper clamp body, and the trigger part includes a first protrusion arranged on the lower side of the upper clamp body A block, and a second protrusion disposed on the upper side of the lower jaw body, the first protrusion and the second protrusion are matched through an inclined surface. The invention solves the problems of difficulty in assembling the split pins in the assembling process of the triple idler rollers of the existing belt conveyors to meet the technical standard requirements and low assembling efficiency.

Description

technical field [0001] The invention relates to the field of assembling cotter pins, in particular to a cotter pin bending pliers. Background technique [0002] With the development of science and technology, the transportation capacity and transportation distance of belt conveyors have been continuously improved, and the length of the fuselage has also been realized from several hundred meters to several kilometers or even tens of thousands of meters. As the main part of the belt conveyor, the idler supports the conveyor belt so that the sag does not exceed the limit value and reduces the running resistance of the conveyor belt. After continuous mining, the matching belt conveyor generally adopts triple rollers. Between the three rollers, two connecting plates are used to connect the roller shaft with cylindrical pin B, and the cylindrical pin B is locked with a split pin to limit the axial displacement. Hanging mounted on the stringer. [0003] At present, the triple rol...
