The telescopic movable joint is engaged therebetween, and the other end of the sleeve rod 13 is fixed to the positioning member 11. The rod 10 and the sleeve 13 are sleeved into the spring 9, and the two ends of the spring 9 are respectively placed on the two

positioning members

7, 11.

The positioning member 11 is rotated and matched with the positioning rod 12. The upper and lower ends of the positioning rod 12 are respectively placed into the guiding and positioning holes of the top plate 1, the bottom plate 2, and can slide along the guiding and positioning holes. The positioning rod 12 is rotatably coupled with the two parallel guiding guides 16. The other end of the two guiding pieces 16 is connected with a guiding rod 17, and the guiding rod 17 is rotatably engaged with the guiding piece 16.

The guiding rod 17 is rotatably engaged with the two transmission members 18, the two transmission members 18 are facing to both sides, and the two transmission members 18 are in the foregoing The centerline of the notch is symmetrically laid out on the basis of the reference. The other end of the transmission member 18 is rotatably coupled to one end of the two top contact pieces 21 via the shaft 19. The top contact pieces have the same shape and are arranged in parallel up and down. The other ends of the two top contacts 21 are fixedly connected by a connecting rod 22, and the middle portions of the two top contact pieces 21 are rotatably mounted between the top plate and the bottom plate by the support shaft 20. The end of the top contact piece 21 is the top contact end 21-1, and the top contact end 21-1 forms a top contact surface which faces and contacts the back surface of the brake block 5 (the side corresponding to the clamping surface).

One of the shafts 20 is also rotatably coupled to one end of the two locking hooks 14. The two locking hooks are identical in shape and arranged in parallel in the upper and lower directions, and the other ends of the two locking hooks 14 are connected by a connecting rod 15. A hook groove 14-1 is formed on the lock hook 14, and the hook groove is fitted with the positioning rod 12.

The upper and lower parts of the electromagnet 23 are fixedly connected to the top plate 1 and the bottom plate 2 through a

vertical plate

24, 25, respectively. The movable head 23-1 of the electromagnet 23 is provided with an energy storage spring 26, and the electromagnet 23 is in an energized state, and the movable head 23- 1 Retracts and compresses the spring 26. A tension spring 27 is further connected between the upper riser 24 and the upper end of the connecting rod 15.

The two ends of the screw 30 are rotatably positioned on the mounting plate 28, the positioning seat 31, and the positioning seat. 31 is fixed to the vertical plate 3 on one side by screws. The screw 30 is screwed through the nut 32. When the screw 30 rotates, the nut 32 moves along the screw 30, and it can push the guide piece 16 to be reset, and under normal conditions, the nut 32 does not hinder the triggering action of the guide piece 16. . In order to prevent the rotation of the nut 31, an anti-rotation rod 33 is fixed between the plate 28 and the positioning seat 31. The anti-rotation rod 33 is parallel with the screw 30, and a part of the nut 32 forms a concave portion corresponding to the rod 33. The anti-rotation rod 33 is placed, and the sliding fit between the two causes the nut 32 to move only and cannot rotate.

The triggering process: the electromagnet 23 is de-energized, and the movable head 23-1 is ejected outwardly under the restoring force of the accumulator spring 26 and touches the connecting rod 15, thereby rotating the locking hook 14 with the pivot 20 as an axis. The hook groove is disengaged from the locking of the positioning rod 12; after the positioning rod 12 is unlocked, it slides along the guiding and positioning holes under the force of the spring 9, and simultaneously drives the guide piece 16 to move, so that the guiding rod 17 moves away from the gap along the guiding hole. In the process, the guide rod 17 pushes one end of the top contact piece 21 to the outside by the transmission member 18 on both sides, and the top contact end 21-1 of the top contact piece 21 is pressed against the opposite side. Block 5, the brake block 5 is translated to the opposite side until the brake pads 5 on both sides grip the elevator guide. At this time, the tension spring 27 is in a stretched state. See Figure 6.

The resetting process is to start the motor 29, which drives the screw 30 to rotate, thereby moving the nut 32 along the nut 32 until the nut 32 pushes the guide piece 16 to perform the reset rotation, and the positioning rod 12 slides along the guiding and positioning holes to compress and slide the spring 9 and other components. The resetting action is also performed, until the clamping surface of the braking block 5 is level with the longitudinal plane of the corresponding edge of the notch (the resetting action of the braking block 5 can be achieved by the tension spring, and the one end of the tension spring is hooked to the braking block). On the back side, the other end is hooked on the same side of the riser (not shown), and the elevator guide rail can be worn normally. At the same time, the electromagnet 23 is energized to reset the movable head 23-1, which again causes the accumulator spring 26 to be in a compressed state; the lock hook 14 also returns to the normal position by the restoring force of the tension spring 27 to lock the positioning. Rod 12. Subsequently, the motor 29 is reversed to reset the nut 28 to its original position.
