The invention discloses a tensioning device and a construction method for charge of a solid rocket motor. The device includes a plurality of support plates, the support plates are arranged vertically and form a circle, and gaps are arranged between adjacent two support plates , the upper part and the lower part of the inner wall of each support plate are respectively connected with at least one support rod, and the center of the circle surrounded by the support plates is provided with a fixed plate. The first connecting plate, the second connecting plate and the cylinder are symmetrically arranged, and the output rod of the cylinder passes through the second connecting plate and the first connecting plate in turn and is fixed with the shaft sleeve; There is a fixing ring, and one end of the strut is connected with the support plate, and the other end is connected to the fixing ring. The device solves the problems of manual operation and air entrainment after the large-diameter round tank drug blocks of the solid rocket motor are bonded in pieces.
Description
technical field [0001] The invention belongs to the technical field of rocket motor charging, and relates to process equipment, in particular to a tensioning device and a construction method for solid rocket motor charging. Background technique [0002] In the past, there are two types of charge in the expansion structure of solid rocket motors, namely the screw expansion device and the taper sleeve expansion device. The screw expansion device is composed of a barrel section and a support plate assembly. Uniformly distributed threaded holes are designed on the barrel section. Manually operate the screw to respectively contact the support plate assembly with the drug column to bond the drug column to the shell; the taper sleeve expansion device mainly It is composed of taper sleeve, fixed plate, moving plate, screw, etc. The taper sleeve has uniform grooves, and the screw rod connects the fixed plate and moving plate, and the expansion and tightening is realized through the t...
