[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0020] See also Figures 1 - 5 , the utility model provides a technical solution.

[0021] A bucket elevator operation safety protection mechanism comprises an equipment frame 1, a traction rope 2 and a bucket 3; the equipment frame 1 is used to support the mechanism components, and an emergency stop component and a safety buffer component are arranged on the equipment frame 1;

[0022] The emergency stop assembly includes: a safety frame 4, a sliding frame 5, a slide 6, a support frame 7, a telescopic rod 8, a spring 9, a connecting hinge 10, a sensor switch 11, a pressing frame 12, a driving frame 13, an induction cylinder 14, an emergency stop frame 15, a mounting groove 16 and an emergency stop tooth 17;

[0023] The slide 6 is opened on both sides of the surface of the equipment frame 1, the sliding frame 5 is installed on the safety frame 4, and the safety frame 4 is installed on the slide 6 through the sliding frame 5. The support frame 7 is installed on the side of the machine bucket 3, the telescopic rod 8 is installed on the support frame 7, and the connecting hinge seat 10 is installed on the telescopic end of the telescopic rod 8. The spring 9 is sleeved on the telescopic rod 8 and the upper and lower sides are respectively connected to the support frame 7 and the connecting hinge seat 10. The traction rope 2 is connected through the connecting hinge seat 10. The pressing frame 12 is installed on the connecting hinge seat 10 and aligned with the induction switch 11. The driving frame 13 is installed at the bottom of the safety frame 4, and the induction cylinder 14 is installed in the driving frame 13. The emergency stop frame 15 is connected to the telescopic end of the induction cylinder 14, and the mounting groove 16 is opened on the equipment frame 1, and the emergency stop teeth 17 are arranged and installed in the mounting groove 16.

[0024] The safety buffer assembly includes: a chain 18, a buffer groove 19, a shock absorbing damper 20 and a buffer plate 21;

[0026] It should be noted that when the traction rope 2 pulls the bucket 3 to rise, the safety frame 4 can move with the bucket 3 on the slide 6 through the connection of the chain 18. Once the traction rope 2 pulling the bucket 3 is broken, the tension on the spring 9 disappears, so that the spring 9 will drive the connecting hinge 10 to retract, and then the pressing frame 12 can be driven to touch the sensing switch 11, so that the sensing cylinder 14 is started, thereby pushing the emergency stop frame 15 down to the installation groove 16 and engaging with the emergency stop tooth 17, and then the safety frame 4 can be stopped urgently, and then the bucket 3 can be taken over, and the buffer plate 21 and the shock absorber 20 on the safety frame 4 can reduce the impact of the bucket 3 on the safety frame 4, thereby completing the safe acceptance and protection of the bucket 3.

[0028] It should be noted that the rubber pad is used to provide buffering protection for the bucket 3 .

[0029] Preferably, furthermore, the telescopic rod 8 and the spring 9 are both in an extended state during the ascending process of the bucket 3.

[0030] It should be noted that the telescopic rod 8 and the spring 9 in the extended state can ensure that the pressing frame 12 does not touch the induction switch 11 when the bucket 3 ascends.

[0031] Preferably, furthermore, the induction switch 11 and the induction cylinder 14 are associated with each other by an electrical signal.

[0032] It should be noted that when the induction switch 11 is touched by the pressing frame 12, the electrical signal can transmit an instruction to the induction cylinder 14, thereby completing the induction transmission process.
