Energy storage mechanism for spring operating mechanism

Abstract

The invention relates to an energy storage mechanism for a spring operating mechanism. The invention provides an energy storage mechanism for a spring operating mechanism. The spring operating mechanism comprises a rack, an energy storage spring, an energy storage pull rod and a transmission part; a connecting block is hinged to the matched end of the transmission part and rotationally arranged on the transmission part; the hinge axis of the connecting block and the matched end of the transmission part is a connecting block hinge axis; the rotating axis of the connecting block and the transmission part is a connecting block rotating axis; the connecting block hinge axis and the connecting block rotating axis are coplanar and perpendicularly intersect with each other; the connecting block rotating axis is parallel to the rotating axis of the transmission part relative to the rack; the normal direction of the plane where the connecting blockrotating axis and the connecting block hinged axis are located is the extending direction of the energy storage spring; a lug plate can swing relative to the connecting block, so that lateral component force generated when the center line of an energy storage pull rod and the center line of the energy storage spring are not collinear due to assembly accumulative errors is reduced or eliminated, so that the stability of the energy storage mechanism for the spring operating mechanism is improved.

Description

Technical field[0001]The present invention relates to an energy storage mechanism for a spring actuator.Background technique[0002]Since the spring opener structure is simple, the cost is low, therefore widely used in the 220kV level and the following circuit breaker mechanism. During the operation of the mechanism closing, due to the presence of the accumulation error during the assembly process, the ratchet connection of the energy storage tie rod and the spring operation mechanism is easily skewed to the ratchet axial direction, and the energy storage pulling rod is larger, The stability of the spring octic mechanism is much more affected.Inventive content[0003]It is an object of the present invention to provide a spring operating mechanism for energy storage mechanism for solving the current spring operating mechanism for energy storage mechanism to cause a lateral force of the energy storage tie rod to be largely caused by the presence of the accumulation error. Technical issues...
