Retractable type fall arrester provided with integral rescuing device

Abstract

The invention relates to a retractable type fall arrester provided with an integral rescuing device. The retractable type fall arrester provided with the integral rescuing device comprises a shell, a rolling wheel arranged in the shell, a rescuing rod and a buffer box, wherein the rescuing rod and the buffer box are arranged outside the shell. A center shaft is arranged in the shell. The center shaft is sleeved with the rolling wheel, and a braking ratcheted wheel is welded to the center shaft. The retractable type fall arrester provided with the integral rescuing device is characterized in that a driven gear and a brake disk are fixed to the end face of the rolling wheel, two pawls are movably connected to the brake disk, two tension spring shafts are fixed to the brake disk, the pawls are connected with the tension spring shafts through extension springs, the rescuing rod comprises a rotating shaft, the rotating shaft is sleeved with a driving gear, a buffering spring and a shaft sleeve are arranged in the buffering box, and the center shaft is sleeved with the shaft sleeve in an embedded manner. The retractable type fall arrester provided with the integral rescuing device has the beneficial effects that when high-speed impact happens, the pawls centrifugally extend out, the pawls are combined with the brake ratcheted wheel in an embedded manner, the brake ratcheted wheel transmits the impact energy to a buffering spring through the center shaft, the buffer spring releases the impact energy, after impact is completed, a rescue worker starts and shakes the rescuing rod, a falling person is ascended or descended, and therefore the purposes of protecting and rescuing the falling person are achieved.

Description

technical field [0001] The invention relates to the field of safety protection equipment, in particular to a speed difference automatic controller with an integral rescue device used for high-altitude operations or deep well operations. Background technique [0002] Now, with the development of science and technology, the content of high-altitude operations and deep well operations has become more and more frequent, and people's awareness of personal safety has deepened, and the comfort and functional requirements of safety protective equipment have been continuously improved. Although the automatic controller can meet the requirements of safety protection, the general speed difference automatic controller releases the impact energy of the fall unstable, and the unstable impact energy will cause serious personal injury to the faller, and the general speed differential automatic controller completes the control After the fall protection of the fallen person, the fallen person...

[0002] Now, with the development of science and technology, the content of high-altitude operations and deep well operations has become more and more frequent, and people's awareness of personal safety has deepened, and the comfort and functional requirements of safety protective equipment have been continuously improved. Although the automatic controller can meet the requirements of safety protection, the general speed difference automatic controller releases the impact energy of the fall unstable, and the unstable impact energy will cause serious personal injury to the faller, and the general speed differential automatic controller completes the control After the fall protection of the fallen person, the fallen person will be suspended in the air, unable to rise or fall, especially in the narrow space of the deep well, the rescue work for the fallen person becomes more complicated and difficult, and the rescue efficiency is extremely low
