Mobile laboratory for weight standard device

The invention discloses a mobile laboratory for a weight standard device. The mobile laboratory is shaped as a carriage on the whole; four support legs with adjustable height are symmetrically arranged on four corners of the lower side outside a carriage body and are connected with and controlled by an automatic leveling instrument; the automatic leveling instrument is connected with a level sensor; a lifting frame capable of sliding out of the carriage body is cooperatively assembled on a sliding rail on the top in the carriage body; the lifting frame is formed by assembling a longitudinal beam and two crossbeams through bolts; an electric hoist capable of walking freely is assembled on the longitudinal beam; one end of the longitudinal beam is provided with an auxiliary bracket; a large mass comparator and a standard weight are arranged on the bottom inside the carriage body. The mobile laboratory for the weight standard device can realize the whole vehicle level by adjusting the extension lengths of the four support legs before verification and provides the basis for horizontal adjustment of the large mass comparator in the mobile laboratory, and the verification operation can be carried out by lifting the weight through the electric hoist just by extending the lifting frame equipped for the mobile laboratory to a lifting position and well mounting an auxiliary support.
