Anti-falling pin for power transmission line

Abstract

The invention discloses an anti-falling pin for a power transmission line, and relates to the field of power transmission line engineering. An iron tower is assembled, all components are connected through bolts, in order to guarantee the safety and stability of connection, except nuts for fixation, screws with holes in the tail portions are used, pins are inserted into the screws, traditional pinscan be roughly divided into cotter pins, closed pins and the like, but due to the fact that the structure is too simple, hidden danger such as loosening and falling of the pins often exists. The anti-falling pin comprises a first arc part, a second arc part, a first straight line part and a second straight line part which form a runway shape, the right end of the first arc part is folded inwardsto form an inwards-folded straight line part, the upper end of the second straight line part extends to form an outwards-extending straight line part, the right end of the first arc part is tightly attached to the second straight line part, and the inwards-folded straight line part and the outwards-extending straight line part are coplanar with the runway-shaped main body structure. The anti-falling pin is simple in structure and good in sealing performance, the moving space of the pin can be effectively limited in the bolt hole, the pin cannot loose and fall off easily, and the safety is improved.

Description

technical field [0001] The invention relates to the field of power transmission line engineering, in particular to an anti-falling pin used for power transmission lines. Background technique [0002] In actual engineering, the iron tower is assembled and all parts are connected by bolts. In order to ensure the safety and stability of the connection, in addition to the nuts, a screw with a hole in the tail is used and a pin is interspersed in it. Traditional pins can be roughly divided into open pins and closed pins, etc., but because the structure is too simple, there are often hidden dangers such as pin loosening and falling off; in addition, the material of the pins becomes unstable and easily damaged after being exposed to wind and sun in the external environment. It needs frequent replacement, investigation, and elimination of hidden dangers, which increases the maintenance workload.
