The invention discloses a track varying device which consists of a linear motor, a feeding push rod, a fixed bracket, a movable bracket, a linear track, an arc track, a linear forked road, an arc forked road, a main trunk, guide rails, expansion bolts, bottom fixing reinforcing plates, lateral positioning plates, upper C-shaped sliding ways, lower T-shaped sliding blocks and self-locking mechanisms, wherein the linear motor is fixed on the fixed bracket; an output shaft of the linear motor is connected with the feeding push rod through keys so as to exert moment in the linear direction to the feeding push rod; the feeding push rod is connected with the movable bracket through hinge pins; two guide rails are distributed on the left and right sides of the linear motor; each guide rail is provided with two parts, namely the upper C-shaped sliding way and the lower T-shaped sliding block; the lower T-shaped sliding blocks which can move in the axial direction are mounted inside the upper C-shaped sliding ways. By controlling the linear motor, the feeding push rod is in a stretched or contracted state, then connection or disconnection of lines of the two tracks is achieved, and thus track variation is achieved; the device is applicable to places with small space and track variation requirements, such as nuclear power station plants and maintaining rooms.
Description
Technical field: [0001] The invention relates to a track changing device, in particular to a special device for realizing track exchange in a narrow space, and belongs to the technical field of cranes. Background technique: [0002] There are many types of track changing devices at home and abroad, and they are used in different working environments. Most of them use more complicated driving mechanisms and motion guiding devices, which require a large layout space; according to different uses, the structures are different, and some use rotating motors directly. The rotary track realizes the rail-crossing docking, and some use gear mechanisms, and there are also manual rail-passing devices; but most of them have the defects of large volume, complex structure, and low reliability. [0003] Depending on the usage environment, the functions and implementation methods are also different. Invention content: [0004] The invention proposes a novel track changing device aiming at...
