The invention provides a hot knife actuated split nut type compression releasing device. The device comprises two hot knives, two heat transfer sleeves, a two-petal type split nut, a rope harness, a bearing bolt, a waveform elastic washer and a spherical washer which are arranged in a space defined by a top cover and a base. The two-petal type split nut is arranged in the center of the space defined by the top cover and the base; the two heat transfer sleeves are symmetrically fixed on two petals of the two-petal type split nut; one hot knife is arranged in each heat transfer sleeve; the ropeharness is wound on an outer surface of the two-petal type split nut and the outer surface of the heat transfer sleeve; and in the locking state, the two-petal type split nut and the heat transfer sleeve are tightly bound, the spherical washer and the waveform elastic washer are arranged in an area defined by the lower portion of the two-petal type split nut and the base, and the bearing bolt sequentially penetrates through the base, the waveform elastic washer and the spherical washer and then is connected with the two-petal type split nut. The device is reliable in locking and safe in release, and has characteristics of a low impact, no pollution, low energy consumption, a high bearing capacity and miniaturization.
本发明提供了一种热刀致动的分瓣螺母型压紧释放装置,包括设置在由顶盖和底座围成的空间内的两个热刀、两个传热套、两瓣式分瓣螺母、绳索线束、承载螺栓、波形弹性垫圈和球面垫圈,两瓣式分瓣螺母设置在由顶盖和底座围成的空间的中心处,两个传热套对称固定在两瓣式分瓣螺母的两瓣上,在每个传热套内设置一热刀,绳索线束缠绕在两瓣式分瓣螺母的外表面及传热套的外表面,锁紧状态下将两瓣式分瓣螺母和传热套紧密绑定,球面垫圈和波形弹性垫圈设在两瓣式分瓣螺母的下部与底座围成的区域内,承载螺栓依次穿过底座、波形弹性垫圈和球面垫圈后与两瓣式分瓣螺母连接。本发明锁紧可靠、释放安全,具有低冲击、无污染、耗能小、承载大、小型化特点。
