The utility model discloses a portable flight control computer host test device, which comprises an upper computer and a test unit, and the upper computer is composed of a microcontroller and a display unit. The microcontroller is used for determining test requirements of equipment to be tested and sending the test requirements to the FPGA in the test unit through the Ethernet. A plurality of excitation signals are stored in the FPGA, and the FPGA selects an appropriate signal as a test signal according to a test requirement and transmits the test signal to a device to be tested through a 1553B protocol. The to-be-tested device generates an output signal according to the received test signal, and the display unit is responsible for analyzing and displaying the output signal. The device is small in size, convenient to carry and move and capable of being flexibly used in different places, the device to be tested does not need to be moved to a fixed testing position, and operation complexity and uncertainty caused by space and environment limitation are greatly reduced.

The utility model discloses a transfer device for welded pipe production, including the flatcar, the four corners of flatcar all are fixedly connected with L type board. The utility model discloses through the corresponding card block is pushed to move to the rear side, and card block enters the inside of card slot group, and at the same time, the insertion slot of rear side is separated with the elastic plugboard of rear side, and the insertion slot of front side is inserted with the elastic plugboard of front side, and the most top limit board is fixedly connected with the lifting rod through card slot group and card block, and starts electric cylinder, and electric cylinder drives the lifting rod to move upwards, and the lifting rod drives card slot group, card block and the most top limit board group to move upwards, need to move other corresponding card block and card slot group insertion mechanism, after all card slot group and card block are inserted, and the lifting rod can lock limit board group clamping welded pipe, has the advantage that can save the effort operation, and the limit board group of each layer is controlled through the pushing assembly, does not need manpower to pull, and the use convenience of transfer device is reduced.
