Description
Technical field
The utility model relates to high-rise working personnel in the industries such as a kind of fall protection equipment that uses, particularly electric power, communication and building in shaft tower process up and down and anti-fall rail brackets and anti-fall track-type facilities in the guidance type falling proof device that uses in the horizontal shift process on the iron tower cross-arm in climbing.
Background technology
The guidance type falling proof device is to be used for shaft tower equal-height position operating personnel climbing, moving and the operation process skyborne protective articles of back safety suspension that falls; this device mainly is made up of parts such as anti-fall guide rail, catching device and safety belts, has been widely used at present in the vertical climbing protection and the protection of horizontal shift process of power system iron tower.Anti-fall guide rail has steel wire rope guide rail and the two kinds of forms of custom-designed section bar guide rail that are stretched on the iron tower in this device, wherein the steel wire rope guide rail with its easily install, characteristics such as corrosion-resistant, non-maintaining, anti-saw and generally being adopted.
Chinese patent ZL200520030467.7 discloses the anti-fall guide rail of steel wire rope of " a kind of flexible guide rail emergency support and flexible guide rail device " by name, a kind of iron tower pin nail that utilizes installs and fixes, in iron tower process up and down, implement the anti-fall guide rail of protection, wherein, the guide supporting clamp of flexible guide rail emergency support be by bolted between support body and pressing plate, the guide supporting clamp is formed by sheet metal plate doubling bending, form the guide rail that mates with steel wire rope at its crooked position and pass through ring, this constitutional detail is many, assembling procedure is loaded down with trivial details, the guide supporting clamp is also loosening easily in the middle of using, even tear distortion, cause potential safety hazard; In addition, this support is fixing with form and pin nail that installing hole on it passes the pin nail, need lay down the clamp nut that pin nails on earlier during installation, particularly when lower end frame is installed, because of the securing member of iron tower lower has all adopted anti-theft measure, new pin nail just can be installed so must be sawed-off original pin nail changes the outfit, and work progress complexity, efficient are low.The flexible guide rail device that this patent provides, its steel wire rope directly passes by encircling from each guide rail, because of without any other fixation, the phase mutual friction so micro-play can take place causes steel rope abrasion, guide rail by the ring corrosion between the two, if things go on like this reduced the security of guide rail, even the guide rail that is sleeved on the steel wire rope is given riveted and fixed by ring, be non-sealing because of guide rail by ring also reduction of service life, after its fastening bolt was loosening, riveted joint still can lose effectiveness; In addition, in this device, if after steel wire rope ruptured from a certain position, centre, the steel wire rope of former tensioning was lax at once, causes whole track-type facilities loss of function, the workmen on the iron tower then can lose protection.
The workmen is on the iron tower cross-arm during horizontal shift; implement the anti-fall guide rail of level on the cross-arm of being mounted in of protection; the anti-fall track-type facilities of level of steel wire rope form is to utilize to be installed in the gaily decorated basket screw at steel wire rope two ends with the steel wire rope tensioning at present; the other end of gaily decorated basket screw is hooked on the link plate that is fixed on the steel tower corner iron; the mid portion of steel wire rope then utilizes some rail bracketses of being installed on the steel wire rope to be connected with angle steel on the iron tower cross-arm; in this structure; steel wire rope only is to be installed in the steel wire loop of rail brackets; be movable between the two; if steel wire rope ruptures; the steel wire rope at breakpoint two ends is in a single day stressed must be deviate from from the steel wire loop of rail brackets; this moment, consequence was with hardly imaginable if the workmen is arranged last.
