Abstract
A fall arrest horizontal safety rope device for operation on bridge crane track beam, comprises and is fixed on the cramp bar on steel column on beam, the outside top of cramp bar is provided with protruding slip-off preventing block, is all connected with safety rope between the cramp bar on adjacent steel column.This device can prevent from vertically falling, and for operating personnel provides failure-free safety guard-safeguard, prevents fall injury accident, and is conducive to improve the convenience of construction.
Description
Technical field
The utility model relates to high-altitude working safety protective device, particularly the anti-falling safe rope of operation on a kind of bridge crane track beam.
Background technology
In electrical building, installation and upkeep operation, there is in a large number high-rise working and face limit operation, for example, in the installation and maintenance of crane in bridge type, operating personal need to be walked and operation on track girder.High-rise working workmen need to carry out safety precaution, and carries out aloft the walking of horizontal direction, conventionally need to set up the platform passage with guardrail.But not perfect in structure, or be not easy to set up in the situation of platform passage, workmen needs wear safety belt.The use of safety strap needs movable hooking point, and existing method is to utilize the existing frameworks such as on-the-spot water pipe, truss as hooking point, and the aisle actual needs but the setting of these frameworks is not fitted, causes its protective capacities low; And framework is provided with a plurality of nodes, workmen must frequently change hooking point, and this has greatly affected the convenience of construction.
Summary of the invention
The utility model aims to provide the fall arrest horizontal safety rope device of operation on a kind of bridge crane track beam, to improve operating personal safety and convenience during operation on the track girder of crane in bridge type.
The fall arrest horizontal safety rope device of operation on bridge crane track beam described in the utility model, factory building arranges many vertical steel columns, the partial fixing of each steel column above track girder is provided with strut bar, between the strut bar on adjacent steel column, be all connected with safety rope, on each strut bar, be also provided with and prevent that safety rope is from the slip-off preventing block of strut bar outer end landing.
The fall arrest horizontal safety rope device of operation on bridge crane track beam described in the utility model, operating personal is on track girder during operation, by safety strap is hooked on safety rope, restriction and traction at safety rope, both made operator conveniently on track girder, walk, can realize the safety precaution to operating personal by failure-free again, avoid the accidental falling of operating personal.It is easy to operate, safe and reliable.And described device, strut bar is installed on steel column, and safety rope is arranged between the strut bar on steel column, and its total setting fits in body of wall, can, to construction, equipment installation and current impacting, also not improve the convenience of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fall arrest horizontal safety rope device of operation on a kind of bridge crane track beam.
Fig. 2 is the partial enlarged drawing of Fig. 1 shown device.
Fig. 3 is the schematic diagram of local side shown in Fig. 1.
The specific embodiment
As shown in Figure 1, 2, 3, the track girder 101 of crane in bridge type is positioned at the both sides of factory building, and the top of track girder 101 is the Crane Rail of Operation Van 102, and the factory building wall in track girder outside is provided with many vertical steel steel columns 103.The fall arrest horizontal safety rope device of operation on described bridge crane track beam, on each steel column above track girder, fixedly mount strut bar 1, the slip-off preventing block 2 that the arranged outside of strut bar 1 raises up, 1 of strut bar on adjacent steel column is all connected with safety rope 3; Described safety rope 3 be take the high-tensile ropes such as steel rope as good.
Safety rope 3 can comprise multistage, and each section of safety rope is connected between adjacent cramp bar, and its installation fastness is strong.
Safety rope 3 can be also a whole piece, and it is wound around after the strut bar at each middle part, and two ends are individually fixed on the strut bar 1 of two avris, or two ends are placed on respectively the strut bar of two avris and fix by wire clips.One root safety rope connects all strut bars, and its structure is simpler, easier for installation.But a safety rope connects all strut bars, between each strut bar, the surplus of safety rope can migration between each strut bar, when operator falls downwards at one section of safety rope place, the surplus of adjacent safety rope can be shifted to by the section of drawing with the drop-down of rope, thereby the distance that operator falls can be taught greatly, still may bring injury to operator.For fear of surplus migration, safety rope can be wrapped on each strut bar of middle part by compound fast knot.It can avoid the surplus migration of safety rope, thereby avoids tenesmus distance excessive, guarantees that every section of tenesmus distance is all in the scope of setting, thereby further improves safety.
Strut bar 1 is advisable with pipe, on pipe, without corner angle, can avoid the safety rope being wound around to wear and tear, thereby safer.
Slip-off preventing block, can be only one be positioned at strut bar outside, can be also a plurality of outsides that are evenly arranged in strut bar, a plurality of slip-off preventing blocks, more failure-free prevents from coming off, and can avoid the local shedding phenomenon of safety rope.
Consider making full use of of main building space, constructability personnel walk simultaneously, conventionally on the body of wall above beam, have the door of turnover, and factory building is provided with the cat ladder that leads to door outward, and workmen enters aisle beam from Men Chu.Because the height of safety rope is generally 1.2 meters of convenient operation, if do not adjusted, the setting of safety rope is crossed and is moved into one's husband's household upon marriage from door middle part, can personnel's turnover and walking be made troubles and be affected, and even may trip operator, causes danger.For overcoming the above problems, the fall arrest horizontal safety rope device of operation on bridge crane track beam, can arrange under reveal limit and door and walk around the accessible framework 4 on doorway, described accessible framework 4 is all equipped with pulley 5 in each corner, and safety rope 3 is walked around pulley 5 successively.By the setting of accessible framework and pulley, safety rope can get around doorway, avoids personnel's turnover to impact.
Button for safety strap is hung mode, can not directly with the crampons of safety strap, directly detain and hang on safety rope, preventing that crampons and safety rope from impacting causes rope part contacted by wedge angle, causes it stressed excessive and destroy, and can adopt U-shaped snap ring as the transition of safety-belt metal hook and safety rope.In like manner, can not interlock with safety rope by the rope part of safety strap, prevent the crooked excessive and stressed fracture after socket mutually of filament in rope strand.When operating personnel column one across forward to another across time, should be first the little cord of U-shaped snap ring cover be enclosed within fixedly on steel pipe, when preventing from unclamping safety buckle, it automatically slide into anti-fall arrest level rope across position, bottom.
