Spacing adjusting device of prestressed concrete track plate tensioning system

The utility model provides a spacing adjusting device of a prestressed concrete track plate tensioning system, which comprises a support structure and a conversion structure, and the conversion structure is arranged between two adjacent tensioning locking mechanisms through the support structure; the conversion structure comprises a coupler, a transmission part and a conversion block which are connected in sequence, an output shaft of the driving device is fixedly connected with the coupler, the driving device drives the conversion block through the transmission part, and the conversion blockis used for adjusting the distance between every two adjacent tensioning locking mechanisms. According to the distance adjusting device of the prestressed concrete track slab tensioning system, the distance between every two adjacent tensioning locking mechanisms can be flexibly changed through the corresponding conversion structure, flexible conversion between different tensioning systems can beachieved, and prestressed
