Description
Technical field
The utility model relates to fall arrest lifesaving technical field of safety devices, relates to especially that to be used for the work high above the ground personnel with belt, under flip-flop action situation, and device that can automatic falling-proof.
Background of invention
In industries such as the power transmission and transformation of power system, telecommunication, chemical industry work high above the ground is arranged all, need ascend a height; In building field, the construction of highrise building, maintenance, maintenance also often relate to ascend operation, owing to there is not reliable falling-proof safety device, safety code can't be implemented, and causes the accident in the ascend operation to take place frequently; As China's power industry regulation, ascend operation must not lose the safety belt protection, and in fact, shaft tower can't be brought into play the safety belt effect up and down; A kind of " falling proof device of ascending a height " (patent No.: 96227757.6) was once disclosed on China's utility model patent communique, its anti-falling device one end is a crotch shape, can hook special cat ladder column, the opening part of crotch is withstood by bearing pin, make openings get smaller, anti-falling device is unlikely from the column slippage, can pass through treadle again; This kind structure when the operating personnel climbs, must be handed anti-falling device, and opening is aimed at, and with by treadle, climbs up and climb down all inconveniences, the energy and the notice of disperseing the people easily; China's patent of invention also disclosed a kind of " work high above the ground personnel's automatic falling-proof devices " (notification number: CN1100576C), it is to be passed in the saturating up and down empty housing by safety rope, locking mode is with cam extruding rope, itself and shell wall are fixed, thereby stop human body to glide, the detection roller is housed, according to acceleration that glides or speed limit control cam action on the bearing pin of cam; Falling accident when this scheme can prevent that the work high above the ground personnel from ascending a height, but can only just be difficult to climb for the big tower body of some base portions vertically; Sometimes the work high above the ground personnel need laterally move to the setting operation after climbing up shaft tower, and this turning is climbed can not depend merely on its solution; Insuring rope in addition is flexible body, rocks easily, makes the operating personnel produce panic sense; And mechanism's relative complex is made the required precision height.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned defective, and a kind of good rigidly, simple in structure, the esy to use, safe and reliable and guide rail external catching device that can turn along certain radian are provided.
For achieving the above object, the technical solution of the utility model is such: a kind of guide rail external catching device, form by guide rail and fall arrest assembly two parts; Guide rail is installed on the climbing thing of type highrise building such as original cable pylon, can vertically be installed on ground, and radian that can also be certain is turned; This guide rail is a trough-shaped body, and its cross section is " C " word or " ∏ " font, and the opening one side outwards, and is relative with human body, and back side sealing one side has the on-slip hole at a certain distance; Said fall arrest assembly comprises parts such as housing, keep plate, spring, keep plate is connected with housing by bearing pin, housing places in the guide rail, in groove, slide with guide rail two sides or open front wall with being accessibly connected, in the middle of being, the back shroud of housing has slotted eye, outside the slotted eye of the extended back shroud of an end of keep plate and the on-slip hole of guide rail, with the slip of locking fall arrest assembly, the other end of keep plate stretches out outside the housing, and the end is provided with the hole that is connected with front hanging type whole body type safety belt; Spring places in the housing, and spring one end and housing fix, and the other end is fixed on the keep plate.
In inactive state, keep plate is under the effect of spring force, and the one end stretches out outside the on-slip hole of the slotted eye of back shroud and guide rail, and guide tracked catching device is in the state of automatically locking; When the personnel of ascending a height climbed, exposing on the end that keep plate is connected with safety belt carried, and keep plate rotates along bearing pin, the compression spring, its end that stretches out is withdrawn in guide rail on-slip the hole outside, fall arrest assembly along guide rail with moving on the human body; When need moved down, the climbing personnel slightly to layback, carried exposing on the end that keep plate is connected with safety belt health, and its end that stretches out outside the guide rail on-slip hole is withdrawn, and fall arrest assembly glides with human body along guide rail; Human body drops suddenly when climbing or moving down, and fall arrest assembly is along with behind the ground run distance down, and keep plate immediately is buckled on the on-slip hole of guide rail under the double action of human body whereabouts impact force and spring force, and fall arrest assembly is locked.
Owing to adopted technique scheme, a kind of guide tracked catching device of the present utility model to have good rigidly, characteristics simple in structure, esy to use, safe and reliable, and can turn, be suitable for all kinds of industries personnel that ascend a height and use along certain radian.
