Description

Technical Field

[0001] The utility model belongs to the technical field of installation anti-falling, and in particular relates to an electric power safety anti-falling device. Background Art

[0002] The internal structure of a fall arrester primarily consists of a buffer mechanism, a catch mechanism, a transmission mechanism, and an actuating mechanism. Components include a ratchet, pawl, steel belt, double stop shaft, outlet protection ring, tension spring, coil spring, ratchet cover, ratchet spindle, and housing. Its core operating principle is essentially the same as the transmission principle. The reverse stop function of the ratchet and pawl, coupled with a speed differential automatic, effectively addresses the reliability issues of the transmission mechanism, achieving effective braking. This provides cushioning protection for personnel at heights during a rapid fall, keeping them suspended above the falling surface and ensuring their safety.

[0003] At present, the existing technology cannot perform auxiliary installation positioning during installation of the fall arrester, which may cause the fall arrester to shift during use. At the same time, the fall arrester is not equipped with an alarm mechanism. When a problem occurs, it is impossible to notify other companions in time, which may cause greater harm.

The battery 406 is installed inside the storage box 408, which is fixedly mounted on the rear end wall of the installation box 401 near the bottom. The central control panel 405 is located inside the installation box 401. The rear end of the installation box 401 is fixedly connected to the front of the fall arrester body 3. The front of the installation box 401 is provided with a mounting cover 403 near the bottom surface. The buzzer 407 is located inside the installation box 401 near the rear end wall.

[0024] In this embodiment, a mounting box 401 is threadedly fixed to the front of the fall arrester body 3. A filter 402 is provided on one side of the mounting box 401 to prevent dust and dissipate heat from the alarm mechanism 4. A buzzer 407 is electrically connected to the central control panel 405. The sound emitted by the buzzer 407 can promptly alert other staff members or companions to check on the falling person. A battery 406 provides power to the alarm mechanism 4.

[0025] See also Figure 4 As shown, the automatic mechanism 10 specifically includes a slide bar 1001, a movable block 1002, a slider 1003, a pressure sensor 1004, and a spring 1005. There are two slide bars 1001 and two sliders 1003. The two sliders 1003 are internally distributed and movably engage with the surfaces of the two slide bars 1001.

After the pressure sensor 1004 senses the pressure, it is electrically connected to the central control panel 405, thereby electrically starting the buzzer 407. The sound emitted by the buzzer 407 can promptly remind other staff members to check the situation of the faller and avoid greater harm. After the faller is relieved of safety, the mounting member 11 is also reset. After the pressure sensor 1004 no longer senses pressure, the buzzer 407 is released, and the spring 1005 resets the movable block 1002.
