Description
Technical field
The utility model relates to the technical field of aloft work anti-falling, and more particularly, it relates to a kind of cable wire drop preventer and installation method thereof.
Background technology
The safety features of work high above the ground is of a great variety, carries out reliably moving or Fixed Point Operation to make work high above the ground personal security, must provide a fixing tie point or a kind of drop preventer reliably comprehensively, carry out safety work to make operating personnel.Drop preventer is for high-rise working personnel skyborne protective articles of safety suspension after climbing, move and falling in operation process.In work high above the ground, normally used falling proof device is guidance type falling proof device at present, generally be made up of critical pieces such as guide rail, self-locking device (catching device), safety belts (rope), mainly produce braking effect by the interaction between self-locking device and guide rail.
At present, application number on market be 201220726027.5 Chinese patent disclose a kind of Anti-fall safety wire, it comprises steel wire rope, arranges slide fastener on a steel cord and corner seating, and steel wire rope two ends are provided with end supports, and slide fastener can be free to slide on steel wire rope and corner seating.Achieve the fall arrest protection to high-altitude fixed point or mobile operating, solve the problem that job area is little, operation transfer efficient is low that former work high above the ground can only fix a point to fix safely.
But, the frame structure that the trapezoidal plate that above-mentioned end bearing is identical with two pieces by the rectangular slab that two block sizes are different is formed, social house roof structure change is various now, described end supports structure is too simple, be difficult to the roofing adapted to now, because end supports, intermediate support and corner seating need to support whole drop preventer, be fixed on roof if bearing cannot be stable, will have a huge impact whole drop preventer security.In addition, described seat structure side-closed, when running into heavy snow weather, heavy snow is piled up, in cleaning accumulating processes of snowpack, when accumulated snow slides to eaves from roofing most significant end, seat structure can stop the landing of accumulated snow, thus accumulated snow can rest on the side of bearing, because accumulated snow gravity can produce certain active force to bearing, thus have impact on the stability of whole drop preventer, easily cause whole drop preventer destructurized and cause security of system coefficient to reduce.
In addition, because rest base lifting surface area is less, for ensureing the relatively stable of system, certain limitation can be there is to the height of system, the deficiency of system height can cause being buried by accumulated snow in heavy snow weather whole system, thus causes drop preventer normally to use, and base lifting surface area is less, not enough to the laminating degree of roofing, also can have a huge impact the stability of whole drop preventer.
In said system, buffer and stretcher separate two ends setting, are not easy to install, and when tension adjusting, need two people to coordinate, increase homework burden.
In system, cable wire and bearing adopt end fitting to be connected, and easily come off, security exists hidden danger.System corner adopts corner seating and curved steel pipe, increases installation quantity, has increased the weight of the work load of work high above the ground personnel, be unfavorable for operating personnel's operation.
In addition, operating personnel is when roof operation, due to the difference of operating location distance, operating personnel can produce a pulling force to the side of system, due to the constraint of system seat structure, seat structure is too fastening, bearing cannot produce certain deformation and buffering, when active force is excessive time, the skew of whole system structure can be caused, thus have impact on security of system, above-mentioned Anti-fall safety wire corner is provided with corner seating and curved steel pipe, structure is comparatively complicated, add installation difficulty and the activity duration of operating personnel, curved steel-tube construction lacks flexibility, deformation buffering cannot be produced when operating personnel applies active force at turning to it, add the load of whole system, there is certain safeguard protection hidden danger.
Therefore, it is very necessary for researching and developing safe and reliable cable wire drop preventer, for ensureing that the security of work high above the ground personnel is significant.
