A method and system for releasing and tensioning a soft track

Abstract

The invention relates to a soft track tension releasing method and a pair of soft track tension releasing systems. The soft track tension releasing method is characterized in that the pair of the soft track tension releasing systems is arranged at an interval; each system comprises a releasing device, a pulley, a tension device and a first steel wire rope, wherein the first steel wire rope bypasses the pulley and then is connected with the releasing device, the heavy end of the steel wire rope is directly / indirectly connected with the tension device, and a second steel wire rope in the tension device is connected with ground anchor points; a braking device of the releasing device can be automatically or manually unlocked, so as to control a soft track to release; the releasing speed of the first steel wire rope of the releasing device is controlled through a speed limiting mechanism arranged in the releasing device; after the operation of the releasing device is completed, the second steel wire rope between the ground anchor points is tensioned on the ground through the tension device; the external force applied to the two steel wire ropes which are connected into a whole is controlled to be within a set range through a force limiting device arranged in the tension device, and the second steel wire rope between the ground anchor points is prevented from being discharged and loosened; the second steel wire rope of the soft track tension releasing system is in a tension state, and a lift car which penetrates through between soft tracks on both sides is enabled to do a reciprocating rectilinear motion, so as to prevent from drifting.

Description

technical field [0001] The invention relates to a method and system for slow descent at high altitude, in particular to a method and system for releasing and tensioning a soft track. Background technique [0002] Generally speaking, when the soft track of the high-altitude slow-descent system device is released, the operator is required to manually release the hand wheel, and at the same time, the operator is required to manually control its falling speed. When the soft track is tightened, the operator needs to manually turn the handwheel in reverse and fix the handwheel to tighten the soft track. Operators are required to operate the system device at the installation location of the equipment (usually the roof). The operation process requires the operator to have a high technical level, and the operation process is cumbersome and takes a long time. As an essential device for rescue equipment, its processing method and system should meet the requirements of simple, convenie...
