Embodiment Construction

[0019] A handcart propulsion mechanism for an indoor single-phase vacuum circuit breaker for electrified railway users according to the present invention includes a transmission shaft 3, a bearing 2, a crank arm 1, a main shaft 4, an end plate 5, a roller 6 and a hexagonal end 7. The transmission shaft 3 is fixed under the handcart of the circuit breaker through the bearing 2 and the bushing. One end of the transmission shaft 3 is a hexagonal end 7 that matches the sleeve rocker arm. The other end of the transmission shaft 3 is composed of two crank arms 1. The ten bytes are connected to spindle 4. Rotate the hexagonal end 7 with the rocker arm to generate torque, so that the transmission shaft 3 rotates, and transmits to the main shaft 4 through the ten bytes formed by the two crank arms 1, so that the main shaft 4 rotates thereupon. The main shaft 4 is fixed on the lower part of the handcart of the circuit breaker and close to the track through bearings. Both ends of the mai...

Abstract

An advancing mechanism of single phase vacuum breaker handcart used on electronic rail way is prepared as fixing a driving shaft at bottom of said handcart through bearing, setting hexagon end on oneend of said shaft and crosshead on another end of said shaft for driving master shaft to rotate when said shaft is rotated, fixing master shaft at bottom of said handcart near to rail, setting end plates with rollers at two ends of master shaft and rollers in guard block of body frame on said handcart for driving said handcart to move back and forward when master shaft is rotated.

Description

1. Technical field [0001] The invention relates to a handcart propulsion mechanism, in particular to a handcart propulsion mechanism for an electrified railway user's indoor single-phase vacuum circuit breaker used in an electrified railway substation. 2. Background technology [0002] With the continuous expansion of rail transit, electrified railways have also been widely used. High-voltage circuit breakers are mostly used in substations of electrified railways. The medium and low voltage power distribution cabinets are mainly used in power plants and industrial and mining enterprises. The medium and low voltage power distribution cabinets mostly use worm gear and rack and pinion propulsion mechanisms. This type of circuit breaker is characterized by small size, light weight, and high distance from the ground. , the operator can drive the circuit breaker to move simply by shaking the handle. [0003] The lever type propulsion mechanism is mainly used in high voltage circ...
