Description
Technical field
The utility model relates to falling-proof safety device technical field, is applicable to high-altitude and the overhead operation of the systems such as electric power, chemical industry, building, specifically a kind of box-like fall arrest track of high-strength complex of end of tape lock.
Background technology
In the systems such as electric power, chemical industry, building, often have work high above the ground, in order to ensure operating personnel's life security, must have falling proof device reliably.Falling proof device be for work high above the ground personnel climbing, prevent from falling during the situation such as move in high-altitude, work high above the ground and starve a kind of security system, to operating personnel, increased the guarantee of safety together.And fall arrest track is one of most important parts in falling proof device.
At present, unit adopts " work " font rail or T-shape rail mostly, also has the flexible guide rails such as aluminium rail, organic material guide rail, steel pipe and a small amount of steel strand wires etc.These falling proof devices are not fitst water safety protective toolses, have local defect.As " work " font or T-shape steel track exist difficult, quality heavy, to the shaft tower shortcoming such as large, perishable of bearing a heavy burden; There is the shortcomings such as safety coefficient is unreliable in aluminium rail; There is the shortcomings such as locking distance, easy swing in flexible guide rail.In addition, existing fall arrest track does not all arrange protective device at its end, just in case catching device is malfunctioning, catching device will be along fall arrest track tenesmus until come off from fall arrest track, cause the generation of falling accident.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of box-like fall arrest track of high-strength complex of end of tape lock is provided.
The utility model is achieved by the following technical solution:
A kind of box-like fall arrest track of high-strength complex of end of tape lock, comprise two parallel sleeve pipes, two sleeve pipes connect by a rectangular strip connecting plate, and two sleeve pipes are fixed on respectively two long limit ends of rectangular strip connecting plate along the length direction of rectangular strip connecting plate; The every intrinsic interior rail of sleeve pipe interpolation, outside and two interior rails that the end of interior rail is exposed at the cannula end mouth of pipe are exposed at the equal in length of sleeve pipe mouth of pipe outside, the part that every interior rail is exposed at outside the sleeve pipe mouth of pipe is also respectively equipped with a draw-in groove, and the draw-in groove on two interior rails is offered relatively; Wherein, described sleeve pipe and rectangular strip connecting plate are made by aluminium alloy extrusions, and described interior rail is made by steel, and interior rail and sleeve pipe are closely combined with each other; Tip lock is arranged on two interior rails and is exposed in the part outside the sleeve pipe mouth of pipe, one end of tip lock is that the collar, the other end are the dop of offering bayonet socket, the collar is sleeved on an interior rail wherein, the bayonet socket of dop is connected in another root on rail, and be plugged on the interior rail in the collar and be also provided with and can make dop upper latch notch fastener be connected on the torsionspring on rail in another root, wherein, the external diameter of the collar and dop is all greater than the external diameter of sleeve pipe; The part that two interior rails are exposed at tip lock outside is provided with fixture, fixture comprises two parallel fixed sleevings, two fixed sleevings by one fixedly rectangular strip connecting plate connect, two fixed sleevings are fixed on fixedly two long limit ends of rectangular strip connecting plate along the fixing length direction of rectangular strip connecting plate respectively, and two fixed sleevings and fixedly rectangular strip connecting plate are isometric and align and fix; Fixedly rectangular strip connecting plate surface offers fixed card access slot, the two ends of fixed card access slot communicate with the inner space of fixed sleeving respectively, the part that two interior rails are exposed at tip lock outside be plugged in respectively in two fixed sleevings of fixture and the draw-in groove on interior rail over against the fixed card access slot on fixing rectangular strip connecting plate, in fixed card access slot, be fixed with fixedly fixture block, fixedly the two ends of fixture block are connected to respectively in the draw-in groove on interior rail.
The utility model fall arrest track is a kind of outer aluminium alloy material, the inner high performance composite track of aluminium Baogang that adopts steel, and this track is through cold-drawn extrusion modling, and whole tension, shearing strength are apparently higher than like product; Process through hardening oxidation on aluminium alloy top layer, is not highly polishedly stained with ash, resistance to corrosion is strong; Two circular shaft structures are curve transition, there is no tongue and groove, and through ice-coating test, surperficial ice cover is far below other structures and Steel material product, and deicing is simply easy, and after a vibrating deicing, residual ice is few, and catching device can pass through smoothly.In addition, this track can also play the antitheft effect of anti-theft, and in built-in steel, rail intensity is high, and crime personnel can not be sawed-off easily.
When operating personnel will go up pole tower operation, the tip lock of long rails end is pulled open to (collar of tip lock of take is center of rotation, the dop that tip lock is stuck on interior rail is pulled away from interior rail), then by catching device sleeve after the sleeve pipe of long rails, then by the dop holding of tip lock on interior rail.When operating personnel falls on long rails, just in case when the latch functions of catching device lost efficacy, longitudinally track tenesmus of catching device, when catching device drops the lowermost end of long rails, the tip lock of long rails end will block catching device and split away off from long rails to prevent catching device, has so also just avoided operating personnel to drop on ground.
The utility model apparatus structure is simple, novel in design; have lightweight, intensity is high, be difficult for corrosion, anti-theft is antitheft, low cost and other advantages; the more important thing is that this track is also provided with the tip lock of fall arrest; even if guaranteed that catching device inefficacy can not make catching device come off from track yet; for work high above the ground personnel provide another pipe protection barrier, be worth of widely use.
