[0038] The utility model provides a pendulum lifting release device, as shown in the figure, it includes: Figures 1-5

[0039] The mounting assembly 1 is horizontally fixedly connected with the rotating drive mechanism 2, and the output end of the rotating drive mechanism 2 is fixed with the connecting piece 3.

[0040] The pendulum assembly 5 includes a swing arm 501 rotatably connected to the mounting assembly 1 and a pendulum 502 fixedly connected to the other end of the swing arm 501.

[0041] The hook assembly 4 includes a hook 401 hingedly connected to the connecting piece 3, a first linear drive mechanism 403 for pushing the hook 401 to rotate to hang the swing arm 501, and a second linear drive mechanism 406 for pushing the hook 401 to release the swing arm 501, both the first linear drive mechanism 403 and the second linear drive mechanism 406 are fixedly connected to the connecting piece 3.

[0042] It can be understood that the first linear drive mechanism 403 can push the hook 401 to rotate to hang the swing arm 501, so that the swing arm 501 is relatively fixed with the connecting piece 3, that is, when the rotating drive mechanism 2 drives the connecting piece 3 to rotate, it can lift the pendulum 502 at one end of the swing arm 501; after lifting to a certain height, the second linear drive mechanism 406 can push the hook 401 to rotate to release the swing arm 501, so as to indirectly release the pendulum 502, so that the gravitational potential energy of the pendulum 502 is converted into kinetic energy, and then knocking is realized; as described above, the pendulum lifting release device can automatically lift and release the pendulum 502 for knocking, which is conducive to realizing automatic determination of friction sensitivity.

[0043] It should be noted that the pendulum 502 is rotated to different angles and heights through the swing arm 501, and the size of the kinetic energy converted is different, and different knocking forces can be generated after falling, thereby facilitating the determination of friction sensitivity of different energetic substances.

[0044] ​It should be noted that the first linear drive mechanism 403 and the second linear drive mechanism 406 can be air cylinders, and the controller can be a PCB board loaded with a C51 single-chip microcomputer.

[0045] It should be noted that the upper end of the swing arm 501 is actually bolted to a connecting disc, and the connecting disc is rotationally connected to the mounting assembly 1, so as to facilitate dismounting of the swing arm 501 and the pendulum 502, thereby facilitating timing detection and identification.

[0046] In one embodiment, the hook 401 includes a hinged portion hinged to the connecting piece 3, a hook portion at one end of the hinged portion, and a pushing portion at the other end of the hinged portion, the first linear drive mechanism 403 and the second linear drive mechanism 406 are respectively located at two ends of the pushing portion, and the output directions of the first linear drive mechanism 403 and the second linear drive mechanism 406 are opposite.

[0047] It can be understood that the output ends of the first linear drive mechanism 403 and the second linear drive mechanism 406 respectively act on the two ends of the pushing portion, so as to make the hook portion rotate in opposite directions around the hinged portion, thereby making the hook portion hang or release the swing arm 501.

[0050] It can be understood that the photoelectric sensor 407 can sense the position of the pushing portion, so as to facilitate the first linear drive mechanism 403 and the second linear drive mechanism 406 to push the pushing portion to an accurate position.

[0052] It can be understood that the output end of the third linear drive mechanism 405 can abut against the end of the pushing portion close to the first linear drive mechanism 403 after being extended, so as to cooperate with the first linear drive mechanism 403 to act on the pushing portion, thereby locking the pushing portion, and further facilitating to improve the stability of the lifting process of the pendulum 502.

[0053] It should be noted that after the first linear drive mechanism 403 is extended, the hook 401 is hung on the swing arm 501, and then the third linear drive mechanism 405 is extended and abuts against the hook 401, so as to lock the hook 401.

[0054] It should be further noted that the third linear drive mechanism 405 can be a normally open single-acting cylinder, which can prevent self-locking when power and gas are cut off.

[0055] In an embodiment, the connecting piece 3 is fixedly connected with a support seat 404, and the third linear drive mechanism 405 is fixedly connected to the support seat 404. The output end of the third linear drive mechanism 405 abuts against and pushes the pushing part after passing through the support seat 404.

[0056] It can be understood that the support seat 404 provides support for the output end of the third linear drive mechanism 405, so as to improve the stress condition of the output end of the third linear drive mechanism 405, thereby facilitating locking of the pushing part.
