Unpowered obstacle pulley

Abstract

The invention relates to a non-powered obstacle-crossing pulley, which includes a shell, a pulley, a bayonet body, and a clamping plate; the device can quickly pass a steel cable at a long distance, has a simple structure, is convenient to use, and is provided with a clamp made of a steel plate sheet metal. The plate is interactively arranged on the pulley, and the clamp is installed in the connecting hole in the middle of the pull plate, clamp plate and guide plate to limit the position of the clamp plate, so that the connection between the pulley and the cable is more firm and the safety performance is improved; the clamp plate There is a gap matching the cable support plate between the upper end and the side wall of the pulley, which is convenient for the pulley to pass through the support plate, eliminating the need to disassemble and replace the pulley during the zipper process, reducing the difficulty of operation and avoiding potential safety hazards; A hanging arm is set to hang the safety rope, and the safety rope and the steel cable are damaged due to friction to avoid the safety failure; two pulleys are set in the housing to make the device more stable during the zipline process and will not shake back and forth.

Description

technical field [0001] The invention relates to a high-altitude safety protection device, in particular to a non-powered obstacle-crossing pulley. Background technique [0002] Working at heights is one of the common tasks in life. When the operator is at a high position from the ground, if the protective measures are effective, there will be no danger of falling; Lead to serious casualties; in the process of high-altitude operations, pulleys are commonly used high-altitude protection tools. The quality and performance of pulleys directly determine people's life safety. It is in the form of a buckle, but this connection method is prone to accidents due to the failure of the buckle spring, and the safety performance is low; and this connection method cannot directly pass through the cable support plate, and it is often necessary to manually remove the pulley from the side of the support plate After being lowered, reset it on the other side of the support plate, because it is...
