Abstract
Official abstract text for this publication.
A transportation device of a withdrawal circuit breaker, including a girder assembly mounted on a front surface of a truck and configured to draw-in or draw-out the truck, a body plate formed in a box type having an opened rear side and coupled to the girder assembly, a pair of sliding plates slidably disposed within the body plate, and a rotational plate rotatably disposed between the sliding plates, wherein the transportation device further includes a stopper protruded at one side of the rotational plate and configured to restrict one of the sliding plates and a connection link having one end rotatably coupled to one end of the rotational plate and another end rotatably coupled to another end of one of the sliding plates.
First claim
Opening claim text (preview).
What is claimed is: 1 . A transportation device of a withdrawal circuit breaker, comprising: a girder assembly mounted on a front surface of a truck and configured to draw-in or draw-out the truck; a body plate formed in a box type having an opened rear side and coupled to the girder assembly; a pair of sliding plates slidably disposed within the body plate; and a rotational plate rotatably disposed between the sliding plates, wherein the transportation device further comprises: a stopper protruded at one side of the rotational plate and configured to restrict one of the sliding plates; and a connection link having one end rotatably coupled to one end of the rotational plate and another end rotatably coupled to another end of one of the sliding plates. 2 . The transportation device of claim 1 , wherein the rotational plate includes at its center a center hole in which part of a lead screw mounted on the truck is inserted. 3 . The transportation device of claim 1 , wherein the pair of sliding plates are coupled to a handle, respectively. 4 . The transportation device of claim 1 , wherein the rotational plate includes at its sides a pair of arms. 5 . The transportation device of claim 4 , wherein the pair of arms are formed asymmetrically. 6 . The transportation device of claim 5 , wherein the stopper is formed at a lower part of one of the pair of arms. 7 . The transportation device of claim 1 , wherein one of the sliding plates includes a spring configured to store a force pulling in a direction of an inner side.
