Provided with multiple through holes, the through hole on the outside of the upper end of frame is held to be used for the joint that will hold frame and solid rocket motor case by bolt
Link together, multiple circular holes are evenly equipped with the inside of the upper end for holding frame, hold the circular hole on the inside of the upper end of frame to be used for threaded circle
Steel is fixed on the circular hole on the inside of the upper end of end frame, and the lower end outside of end frame is provided with multiple through holes, hold frame lower end outside it is logical
Hole is used to fix end frame and testing stand by bolt；Described round steel two ends are provided with screw thread, and round steel one end is fixed to nut
Hold on the circular hole on the inside of the upper end of frame, round steel other end nut fixation steel plate；Through hole is provided with the middle of described steel plate, steel plate leads to
Through hole is crossed installed in round steel one end and is fixed with nut, it is red at the upper surface of steel plate and the end socket of solid rocket motor case
Diatom is concordant；Described solid rocket motor case is fixed on the end frame of end frame assembly, solid propellant rocket
Enclosure interior loads concrete, the height of concrete and the upper surface flush of steel plate.
Beneficial effect：
The device connection of the present invention is simple, safe and reliable, realizes that obtaining solid rocket motor case list skirt axle draws load, both may be used
To be applied to solid rocket motor case list skirt axis pulling experiment, can also be applied to before and after solid rocket motor case skirt by
Carry inconsistent axis pulling experiment.
Brief description of the drawings
Fig. 1 is the device combination schematic diagram for solid rocket motor case list skirt axis pulling experiment；
Fig. 2 is end frame assembly schematic diagram；
Fig. 3 is end frame schematic diagram；
In figure：1 it is dismountable end frame assembly, 2 be solid rocket motor case, 3 be bolt, 4 be concrete, 5 is end
Frame, 6 be round steel, 7 be that nut and 8 is steel plate.
Embodiment
With reference to embodiment, the present invention will be further described.
As shown in figure 1, the present invention is used for the device of solid rocket motor case list skirt axis pulling experiment, experiment mainly includes
Dismountable end frame assembly 1, solid rocket motor case 2, bolt 3 and concrete 4.
As shown in Fig. 2 removably end frame assembly is made up of end frame 5, round steel 6, nut 7 and steel plate 8.The two of round steel 6
Side is provided with the screw thread of certain length.Steel plate 8 is provided with through hole.The surface of steel plate 8 is provided with through hole, is connected with round steel 6, for fixed solidification
Concrete afterwards.
As shown in figure 3, the side of end frame 5 is provided with multiple through holes that different distributions are justified, opposite side is provided with multiple through holes.Hold frame
With being provided with multiple through holes with the correspondence position of the connecting socket of solid rocket motor case 2 on the outside of 5 upper ends, for passing through bolt
End frame 5 be connected with the joint of solid rocket motor case 2, holds frame 5 upper end inner side to be evenly equipped with multiple circular holes, for will be with spiral shell
The round steel 6 of line is fixed in the frame 5 of end on mother rib lateral rotundum；The lower end outside of frame 5 is held to be provided with multiple through holes, with bolt by end frame 5 with testing
Platform is fixed.
The present invention provides a kind of device.With nut by Interal fixation to threaded round steel one end, steel plate is away from round steel end
The distance in face is 30mm, and then the threaded round steel other end is fixed on the inframe mother rib lateral rotundum of end with nut again, passes through nut
Distance of the steel plate away from round steel one end is adjusted, makes steel plate concordant with equatorial line at end socket, then with bolt by end frame and solid-rocket
The joint connection of motor body, is finally 1 by cement and sand weight ratio：2 concrete loads solid propellant rocket shell
Internal portion, concrete height is flushed with steel plate, it is concrete curing after, end frame one end is bolted to Test-bed, burns
Imposed load on room housing list skirt, can be used for solid propellant rocket skirt axis pulling experiment.
