Description
Technical field
The utility model belongs to design and the technical field of improvement of building safety equipment, particularly a kind of safety device arranged on tower crane crane arm for building.
Background technology
Building operation tower crane reckon without when designing stuck in generation dolly mechanical breakdown, motor burns out, power failure etc. in particular cases; maintenance personnel are on tower crane crane arm in walking process; safety strap does not have to hang and slidably fender guard; and cause the generation of falling from high altitude safety misadventure, painful and economic loss is greatly brought to family and enterprise.
Summary of the invention
The purpose of this utility model is: on the crane arm of the tower crane of existing use, design a safety device, when tower crane meets accident accident, can well ensure the staff constructed on tower crane.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme: a kind of safety device arranged on tower crane crane arm for building, comprise the upper of tower crane crane arm and crane arm, lower edge, at least one side of winding up of described tower crane crane arm two ends respectively consolidation steel rope ear is set, same side of winding up middle part at least consolidation two rope holders are set, steel rope one end is connected with the top steel rope ear that winds up by wire clips, the other end is connected by wire clips with the end steel rope ear that winds up through rope holder, steel rope is tightened between two steel rope ears.Described steel rope ear and rope holder are steel, and its shape is hook and loop or tabular with holes.Described wire clips is commercially available steel wire clips.
The beneficial effects of the utility model: the safety device that the utility model describes; reasonable in design; install simple; for convenience detach; can play stuck in tower crane generation dolly mechanical breakdown, motor burns out, power failure etc. in particular cases; ensure that maintenance personnel in walking process, play safety guard-safeguard effect, the generation of preventing high altitude falling accident on tower crane crane arm.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is lateral plan.
Detailed description of the invention
Embodiment 1, a kind of safety device arranged on tower crane crane arm for building, as shown in the figure, comprise the upper and lower string 1,2 of tower crane crane arm and crane arm, 1 at least one side of winding up of described tower crane crane arm two ends respectively consolidation steel rope ear 3 is set, 1 same side of winding up middle part at least consolidation the holders 5 of two ropes are set, steel rope 4 one end is connected with the 1 top steel rope ear 3 that winds up by wire clips, the other end is connected by wire clips with the end steel rope ear 3 that winds up through rope holder 4, and steel rope 4 is tightened between two steel rope ears 3.Described steel rope ear 3 and rope holder 5 are steel, and its shape is hook and loop or tabular with holes.Described wire clips is commercially available steel wire clips.
In practical operation, this safety device is installed after ground assembling elevator boom rack completes, namely install this anchor fitting and steel rope ear in tower crane Liang Ge end, side of winding up, two brackets and rope holder are installed in middle part, fixedly mount one steel rope between two anchor fittings; Steel rope passes middle bracket successively from top device, finally, the mode of short sling is coordinated at tail end fixing device place jack, to bear rope tension, be fixed with being no less than three wire clips, the hook of safety strap hangs on safety rope and walks by maintenance operation personnel, thus form one life safety rope, ensure the life security of personnel when current maintenance, assembling and disassembling, avoid falling from high altitude, play the effect of safety control.Finish using at tower crane, through falling joint, before crane arm drops down onto ground decomposition, then this covering device is removed, recyclable recycling.
