Specific embodiment
Below in conjunction with attached drawing, clear, complete description is carried out to the technical solution in the present invention, it is clear that described
Embodiment is a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
Logical technical staff all other embodiment obtained without making creative work, belongs to protection of the present invention
Range.
Embodiment one
Elevator rope gripper, as shown in Figure 1, Figure 2, Figure 3 shows comprising: rope guarding plate 1, drive rod 2, blocking rod 3, electromagnetic coil
4, spring 5；
The drive rod 2, including the thin segment 21, changeover portion 22, thick section being sequentially coaxially fixed together from front to back
23；
The thin segment 21, thick section 23 are cylindrical；The outer diameter of the thin segment 21 is less than the outer diameter of thick section 23；
The outer diameter of the changeover portion 22 becomes larger from front to back；
The rope guarding plate 1 is fixed on 21 front end of thin segment；
The blocking rod 3 and drive rod 2 are orthogonal direction arrangement, and 3 bottom of blocking rod is resisted against on spring 5；When elevator presss from both sides
When device of restricting does not trigger rope-clamping movement, blocking rod 3 is located at 2 thin segment 21 of drive rod, as shown in Figure 1, when elevator rope gripper has triggered
After acting at rope-clamping, blocking rod 3 is located at the thick section 23 of drive rod 2, as shown in Figure 3；
The electromagnetic coil 4, fixation are set in outside the blocking rod 3；
