Upper and lower two sides are provided with steadying plate 18, and steadying plate 18 and limit sliding rail 20 constitute slide construction, and transmission gear 17 is equal
Connection is engaged with 2 steadying plates 18, so that the transmission gear 17 of rotation drives 2 18 counter motions of steadying plate, thus steadying plate
18 coincide connection with the inner wall of connecting cylinder 5, and connecting cylinder 5 is fixed, and avoid its rotation, steadying plate 18 with limit 20 phase of sliding rail
It connects, and limits sliding rail 20 and be located at the left side inside rack 1, the side of steadying plate 18 is provided with strip 19.
Working principle: when using the safety arrestment electric block, it is installed in the place of needs first, connects later
Power supply, driving motor 2 drives universal driving shaft 8 to be rotated, so that universal driving shaft 8 is rotated with movable reel 3 in the inside of rack 1,
So that the wirerope 4 in 3 outside of reel is gradually fallen, weight is wound using wirerope 4, so that heavy lift is got on,
Reel 3 drives stable pin 6 to be rotated in endless glide 7, improves the stability of the rotation of reel 3, and reel 3 drives and connects
Connect cylinder 5 is rotated；
While 8 uniform rotation of universal driving shaft, universal driving shaft 8 drives connection ring 10 to carry out uniform rotation by fixed link 9, thus
The rotation of the first strength magnetic patch 13 at the uniform velocity inside connection ring 10, the contact for being timed it with the second strength magnetic patch 15, two
It is attracting when person position is to correspondence, reduce from distance between the two, i.e., connecting shaft 21 is stretched out from limit shaft 14, and connecting shaft 21 is right
Elastic 12 is compressed, when the second strength magnetic patch 15 and 15 position of the second strength magnetic patch interlock, between magnetic force reduce, bullet
Property column 12 restore deformation so that connecting shaft 21 comes back to the inside of limit shaft 14；
When driving motor 2 loses braking action, the weight on wirerope 4 drives wirerope 4 to move down, i.e. wirerope
4 drive universal driving shaft 8 rapidly to rotate downwards by reel 3, and universal driving shaft 8 drives connection ring 10 to be rotated by fixed link 9, at this time
Since the speed of universal driving shaft 8 becomes faster, 13 velocity of rotation of the first strength magnetic patch inside connection ring 10 becomes faster, with the second strength magnetic patch
15 times of contact increased, so that the second strength magnetic patch 15 is attracted by magnetic force, it is magnetic attracting with the first strength magnetic patch 13, thus even
