Interval adjusting device of prestressed concrete track plate stretching-drawing system

The invention provides an interval adjusting device of a prestressed concrete track plate stretching-drawing system. The interval adjusting device of the prestressed concrete track plate stretching-drawing system includes a supporting structure and a converting structure, wherein the converting mechanism is installed between two adjacent stretching-drawing locking mechanisms through the supportingstructure; the converting mechanism includes a coupling, a transmission part, and a converting block which are connected in turn; and an output shaft of a driving device is fixedly connected with thecoupling, the driving device drives the converting block through the transmission part, and the converting block is used for regulating intervals between the two adjacent stretching-drawing locking mechanisms. According to the interval adjusting device of the prestressed concrete track plate stretching-drawing system, distances between the two adjacent stretching-drawing locking mechanisms can beflexibly changed through t
