Abstract

The invention provides a wrapping tape type unlocking and separation device driven by explosive bolts, belongs to the technical field of aerospace, and solves the technical problems that the assembly precision is difficult to guarantee, the structure size is large and the impact is great in the prior art. The wrapping tape type unlocking and separation device comprises the explosive bolts, an upper bracket, a lower bracket, a left wrapping tape, a right wrapping tape, wrapping tape connecting springs and explosive bolt detached body collecting devices. The left wrapping tape is in fitting contact with the upper bracket and the lower bracket. The right wrapping tape is in fitting contact with the upper bracket and the lower bracket. The contact parts, on each of the left side and the right side, of the left wrapping tape and the right wrapping tape are fastened together by two parallel explosive bolts. The wrapping tape connecting springs are in threaded connection with the left tape and the right tape. Each of two ends of the right tape is fixedly connected with one explosive bolt detached body collecting device which is used for collecting detached bodies of the explosive bolts. The wrapping tape type unlocking and separation device driven by the explosive bolts has greatly improved bearing capacity is and is simple and compact structure.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a band-wrapped unlocking and separating device driven by an explosive bolt. Background technique [0002] At present, the tape-wrapped unlocking and separating mechanism is widely used in the aerospace field. The traditional strap-type structure includes straps, clamps, explosive bolts and protective devices; a certain number of blocks are evenly distributed around the straps, and the blocks are clamped by tightening the straps, thereby realizing the locking function. For the small tape structure, it is difficult to guarantee its assembly accuracy; the protective device is used to collect the separated body after the explosive separation of the explosive bolt. The traditional protective device is to put the explosive bolt in a metal box, and the separated body will fly out with the The metal box collides, thereby confining the separated body within the metal box. ...
