Abstract
The utility model relates to an anti-falling device of an electrified operational rope ladder. The anti-falling device consists of a rope ladder beam, the anti-falling device, a rope ladder head pillar, an insulating rope and an anti-falling self-locker. The anti-falling device is characterized in that the insulating rope is threaded through the anti-falling device and fixed on the rope ladder head pillar, the insulating rope is fixed with the rope ladder and is provided with the anti-falling self-locker matched with the insulating rope, and the other head of the anti-falling self-locker is a potential personnel safety belt. The anti-falling device provided by the utility model has the advantages that when potential personnel climb up and down the rope ladder and fall because the hands do not grasp firmly or because of other reasons, the anti-falling self-locker locks immediately to prevent the personnel from falling from high-altitude, so that the safety of operators is effectively protected and the safety risk is reduced.
Description
Technical field:
The utility model belongs to the device that keeps in repair transmission line of electricity, refer more particularly to a kind of special-purpose anti-drop device of maintenance rope ladder that is applicable to power supply industry transmission of electricity 110KV-220KV circuit or converting equipment, particularly 110KV-220KV hot line maintenance, power transformation livewire work.
Background technology:
The 110KV-220KV transmission line of electricity, when the charged equipotential live line work of power transformation is stepped on rope ladder, because the current potential operating personnel steps on rope ladder from rope ladder one side, and the current potential operating personnel is installed with a complete set of screening clothing, and the easy slippage of screening clothing gloves very easily causes the security incidents such as falling from high altitude.Therefore, for effectively reducing site safety hidden danger, existing rope ladder is transformed, ensured operating personnel's personal safety, reduce accident rate very necessary and urgent.
Summary of the invention:
There is no anti-drop device in order to overcome existing rope ladder, easily cause operating personnel's personal injury, the utility model provides a kind of anti-drop device of livewire work rope ladder, can make the 110KV-220KV transmission line of electricity, pass through to use this rope ladder anti-drop device when the charged equipotential live line work of power transformation is stepped on rope ladder, can guarantee to finish the work under the prerequisite of safety.Simultaneously also reduced livewire work personnel's security risk, and can increase work efficiency.
The utility model is achieved through the following technical solutions its goal of the invention.
The falling proof device of livewire work rope ladder, consisted of by rope ladder crossbeam, falling proof device, rope ladder head foundation, insulating cord, anti-fall self-locking device, it is characterized in that: pass a bar insulation rope from falling proof device, and be fixed on the rope ladder head foundation, insulating cord and rope ladder are fixing together, a fall-preventing self-locking device that matches with insulating cord is installed on insulating cord, and the fall-preventing self-locking device other end is connected with current potential personal security band.
Described falling proof device is an annulus, is inserted in a bar insulation rope on annulus, is fixed on the rope ladder head foundation.
The utility model has the advantage of as the current potential operating personnel during at the up and down rope ladder, do not hold or other reason when falling because of hand, fall-preventing self-locking device can be locked immediately, prevents falling from high altitude, effectively protects operating personnel's safety, reduces security risk.
Description of drawings:
Accompanying drawing is the utility model structural representation.
In the accompanying drawings, the 1st, rope ladder crossbeam, the 2nd, falling proof device, the 3rd, rope ladder head foundation, the 4th, insulating cord, the 5th, fall-preventing self-locking device.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, the anti-drop device of livewire work rope ladder, that a falling proof device 2 is installed on rope ladder head crossbeam 1, it is characterized in that: fill to fall to putting from fall arrest and pass a bar insulation rope 42, and be fixed on rope ladder head foundation 3, insulating cord 4 and rope ladder are fixing together, and a fall-preventing self-locking device 5 that matches with insulating cord is installed on insulating cord 4, and fall-preventing self-locking device 5 other ends are connected with equipotential personal security band.As the current potential operating personnel during at the up and down rope ladder, not hold or other reason when falling because of hand, fall-preventing self-locking device 5 can be locked immediately, can prevent that falling from high altitude from protecting operating personnel's safety effectively, reduces security risk.
Described falling proof device 2 is annulus, is inserted in a bar insulation rope 4 on annulus, is fixed on rope ladder head foundation 3.
