Description

Technical Field

[0001] The utility model relates to the technical field of elevator emergency braking, in particular to an elevator emergency braking device. Background Art

[0002] Elevators have brought great convenience to people's travel and can be seen everywhere in life. When an elevator encounters an emergency, in order to avoid injuries to the people inside, an emergency brake device must be set up to facilitate emergency braking and ensure the safety of people. When the elevator fails and falls sharply, the existing elevator emergency brake device will cause the temperature of the brake mechanism to rise rapidly due to the intense friction between the brake mechanism and the guide rail. The rubber brake mechanism will generate heat during the friction process, soften quickly and deform, which reduces the braking performance of the elevator and has a poor braking effect. When the elevator emergency brake device is in use, the brake mechanism and the elevator are mostly fixed with bolts. When the brake mechanism is damaged and needs to be repaired or replaced, the workers need to unscrew the screws one by one to disassemble the brake mechanism and install a new brake mechanism. The whole process is cumbersome and will waste a lot of time. Therefore, we redesigned an elevator emergency brake device. Utility Model Content
