Abstract
Official abstract text for this publication.
The present invention relates to a transportation device of a withdrawable circuit breaker, and more particularly, to a transportation device of a withdrawable circuit breaker capable of simultaneously moving right and left handles of a girder assembly for restricting movement of the transportation device or releasing a restricted state. The transportation device of a circuit breaker includes: a truck assembly on which a body of the circuit breaker is loadable; a body plate of a girder assembly installed on a front surface of the truck assembly; a pair of sliding plates slidably installed in the body plate; and a rotation plate having both sides to which leg portions of the sliding plates are rotatably coupled, respectively, wherein the rotation plate is inserted into a lead screw penetratingly-formed at a central part of the girder assembly.
First claim
Opening claim text (preview).
What is claimed is: 1 . A transportation device of a circuit breaker, comprising: a truck assembly on which a body of the circuit breaker is loadable; a body plate of a girder assembly installed on a front surface of the truck assembly; a pair of sliding plates slidably installed in the body plate; and a rotation plate having both sides to which leg portions of the sliding plates are rotatably coupled, respectively, wherein the rotation plate is inserted into a lead screw penetratingly- formed at a central part of the girder assembly. 2 . The transportation device of a circuit breaker of claim 1 , wherein handles are coupled to the pair of sliding plates, respectively. 3 . The transportation device of a circuit breaker of claim 1 , wherein vertical slits for sliding a vertical movement of the sliding plates are formed at the rotation plate, or at coupling parts of the leg portions. 4 . The transportation device of a circuit breaker of claim 1 , further comprising a pair of connection links having one end rotatably coupled to the rotation plate and another end rotatably coupled to the leg portions, respectively. 5 . The transportation device of a circuit breaker of claim 1 , wherein a pair of arms are protruding from the rotation plate in a rotation-symmetrical manner by 180°. 6 . The transportation device of a circuit breaker of claim 5 , wherein the pair of arms are positioned at opposite sides to the leg portions of the sliding plates on the basis of a horizontal center line of the lead screw. 7 . The transportation device of a circuit breaker of claim 1 , wherein a bearing is provided between the rotation plate and the lead screw.
