A self-contracting fall arrester

Abstract

The invention discloses a falling protector capable of contracting automatically. The falling protector comprises a box body; a sealing cavity is formed in the box body; a movable rod capable of moving is arranged in the sealing cavity; the upper end of the movable rod is rotationally connected with a bevel gear shaft; the upper end of the bevel gear shaft is fixedly connected with a first bevel gear; the lower end of the bevel gear shaft is fixedly connected with a second bevel gear; a time-delay device is fixedly connected with the lower end of the movable rod; and the right end of the time-delay device is fixedly connected with a transmission device. The falling protector can be locked firmly after the falling protector is stressed, and a rope in the falling protector automatically contracts, so that a heavy object returns to the safe position, and a device is restored to the initial state again.

Description

Technical field [0001] The invention relates to the field of safety devices, in particular to an anti-falling device that can automatically retract. Background technique [0002] Common fall arresters in people’s use only contain a locking mechanism. After being locked, people need to unlock them by themselves, which lacks efficiency. At present, there is no self-retracting fall arrester, so design a self-retracting device. The fall arrester is really necessary. This device can automatically retract the rope inside the fall arrester to return the heavy object to a safe position and restore the initial state of the device. Summary of the invention [0003] technical problem: [0004] Common fall arresters only contain a locking mechanism when used by people. After being locked, people need to be rescued to unlock it, which lacks efficiency. [0005] In order to solve the above-mentioned problems, this example designs an automatically retractable fall arrester, which includes a box bo...

Problems solved by technology

[0002] In people's use, the general anti-fall device only contains a locking mechanism. After the lock is locked, people need to unlock it by themselves, which is inefficient. At present, there is no automatic retractable anti-fall device, so design an automatic retractable one. The fall arrester is really necessary. This device can automatically shrink the rope inside the fall arrester, return the weight to a safe position, and return to the initial state of the device
