Lifting device of pole-mounted circuit breaker

Abstract

The invention discloses a lifting device of a pole-mounted circuit breaker, and belongs to the technical field of installation of power equipment. The lifting device comprises a pulley, a steel stranded wire and a rope guide mechanism, wherein the pulley is arranged on a pole arm; the rope guide mechanism comprises a box body, a rocking handle, a rotating shaft, a reel, a driven gear and a locking mechanism; the reel is arranged on the rotating shaft; one end of the steel stranded wire is connected with the reel; the other end of the steel stranded wire passes through the pulley and is used for connecting the pole-mounted circuit breaker; the rocking handle is connected with the box body through a shaft sleeve; a driving gear is arranged on the rocking handle and is engaged with the driven gear; the locking mechanism comprises a groove, a bump and a limiting baffle plate; the groove is formed in the box body; the bump is arranged on the rocking handle; and the groove is matched with the bump. The lifting device is small in size, and low in requirements on surrounding service environment of infrastructure and the infrastructure; a lifting operation of the pole-mounted circuit breaker can be relatively conveniently and flexibly carried out; the cost of a crane and manpower for construction is reduced; and compared with a crane operation, the lifting device is high in flexibility, convenient to install and wide in application environment.

Description

Technical field [0001] The invention relates to a lifting device for a pole-mounted circuit breaker, which belongs to the technical field of power equipment installation. Background technique [0002] The pole-mounted circuit breaker is the circuit breaker installed and operated on the electric pole. At this stage, due to the needs of power grid transformation, a large number of pole-mounted circuit breakers need to be replaced or installed. At present, the lifting of the pole-mounted circuit breaker usually requires crane operations and personnel Pole coordination not only requires more workers to cooperate, but also has a high labor intensity, and the cost of using the crane is high, which increases the cost of electric construction. Even the high cost of labor and cranes are acceptable. Some construction environments such as: field or rural operations. Due to the backward infrastructure such as roads, the overall size of the crane is large, inconvenient to move, and unstable, ...

Problems solved by technology

Even the high cost of labor and cranes is acceptable. In some construction environments such as field or rural operations, due to poor infrastructure such as roads, the overall size of the crane is large, inconvenient to move, and unstable, which will not only affect the circuit breaker on the pole. Widely installed applications, but also the possibility of security incidents
