Wire holder device for elevator safety protection

Abstract

The invention provides a wire holder device for elevator safety protection. The wire holder device comprises a wire holder device supporting device, a transmission gear assembly, a fan-shaped pressing plate, an energy storage spring, a first rotating shaft, a second rotating shaft, a transmission arm, a movable clamping plate and a guide bearing shaft; the fan-shaped pressing plate is arranged on the first rotating shaft arranged on supporting plates on the two sides of the wire holder device supporting device; arc-shaped guide grooves are formed in the supporting plates on the two sides of the wire holder device supporting device; the two ends of the second rotating shaft are arranged in the arc-shaped guide grooves, and the fan-shaped pressing plate drives the second rotating shaft to slide in the arc-shaped guide grooves; the upper end of the energy storage spring is connected with the second rotating shaft hinged to one end of the transmission arm, and the other end of the transmission arm is hinged to the movable clamping plate; and one end of the guide bearing shaft is connected with the front supporting plate of the wire holder device supporting device, and the movable clamping plate is arranged on the guide bearing shaft. By means of the wire holder device for elevator safety protection, the clamping force of the movable clamping plate and a fixed clamping plate can be improved, and the wire holder device can be suitable for elevators with the carrying capacity lower than two tons.

Description

technical field [0001] The invention relates to a rope gripper, in particular to a rope gripper device for elevator safety protection. Background technique [0002] The potential safety hazards of elevators include many aspects, among which the accidental movement of the elevator car occupies a large proportion. The unexpected movement of the elevator car includes the abnormal speed of the elevator when it is running and then rushing to the top or squatting at the bottom, and the car moving away from the leveling floor with the door open. Said situation all can bring great potential safety hazard to passenger, relying on the working brake of elevator system itself is unreliable, must arrange the safety braking device independent of elevator system. [0003] After searching the existing technology, it is found that the application number is 201610107762.0, and the invention patent named the rope clamp device for elevator safety protection discloses a rope clamp device for el...

Problems solved by technology

However, this patent is only applicable to the clamping rope braking of elevators with a tonnage of less than 800kg. When braking under an elevator with a higher load, the sliding distance is longer, and the safety of the elevator cannot be guaranteed.
