Active driving type telescopic beam manufacturing pedestal

The invention discloses an active driving type telescopic beam manufacturing pedestal which comprises a plurality of adjustable formwork supporting mechanisms arranged between two end power mechanisms, the adjacent adjustable formwork supporting mechanisms are detachably connected, and the adjustable formwork supporting mechanisms located at the two ends are detachably connected with the corresponding end power mechanisms correspondingly. At least one end power mechanism can drive any one or more adjustable formwork supporting mechanisms to move in the direction close to or away from the end power mechanisms, and all the end power mechanisms and all the adjustable formwork supporting mechanisms are installed on the guide base. According to the invention, it is realized that the device adapts to various different types of prefabricated box girders, a girder manufacturing pedestal does not need to be independently built for each type of prefabricated girder, the construction cost of the prefabricated girder fie
