Problems solved by technology

[0004] However, when the worker is moving in the high-altitude working environment, the steel cable may have been completely released from the rotating part. At this time, if the worker accidentally slips and falls, the braking device cannot be driven by the steel cable to slow down the rotation of the rotating part
Although the other end of the general cable-type fall arrester is fastened to the staff, the staff may be injured due to their own short-term free fall and the tension generated by the rapid arrest of the wire rope.

Embodiment Construction

[0017] Please refer to figure 1 , is a wire rope type fall arrester 1 of a preferred embodiment of the present invention, used to prevent the staff from falling continuously due to accidental slips while working at heights, or to slow down the falling speed of the staff. The fall arrester 1 includes a rotating part 14, a braking device 12, a steel cable 20 and a restraining beam 30, wherein the steel rope 20 is wound around the rotating part 14, and the restraining restraining ring 30 is sheathed on the steel rope 20; the braking device 12 It is connected with the rotating member 14 and is used to limit the rotation of the rotating member 14 .

[0018] The first end of the steel cable 20 is connected with the rotating member 14, and the steel cable 20 can be wound on the rotating member 14 as the rotating member 14 rotates, and the second end of the steel cable 20 is a free end.

[0019] exist figure 1 Among them, the steel cable 20 includes at least a plurality of third coi...

Abstract

A wire rope type fall arrester, including a rotating part, a braking device and a steel cable, the first end of the steel cable is connected to the rotating part; the steel cable includes a first winding ring and a second winding ring wound around the On the piece; the first restricting part of the restricting beam ring is sleeved on the first winding ring, and the second restricting part of the restricting beam ring is sleeved on the second winding ring, so that the steel rope is in the second restricting part and the first winding ring. One end has a fixed length and is wound on the rotating part; when the free end of the steel cable is pulled by an external force, and the steel cable wound on the rotating part is released in a direction away from the rotating part, the restraining beam ring is broken , to release the fixed length of the cable; where the external force is greater than or equal to the tension generated by the free fall of an adult. By releasing the fixed length of the steel cable, the rotating part is rotated and the braking device is driven to act, so that the rotation of the rotating part is slowed down or stopped.

Description

technical field [0001] The present invention relates to a fall arrester; in particular, it refers to a steel cable type fall arrester suitable for high-altitude workplaces. Background technique [0002] In recent years, labor safety has been paid more and more attention. For example, when working at heights, workers should wear a fall arrest device including a safety belt according to regulations. The anti-falling device is fixed on a support, and one end of the safety belt is fixed on the anti-falling device, and the other end is tied to the staff to prevent the staff from continuing to fall due to an accidental fall or to use Buffer the falling speed of the personnel, thereby ensuring the personal safety of the staff. [0003] A general wire rope type fall arrester includes a rotating part, a scroll spring, a braking device and a wire rope. The braking device is connected to the rotating part and is used to limit the rotation of the rotating part. One end of the cable i...
