Description

A kind of anti-dropping soft ladder head
Technical field
The utility model belongs to for electrical domain, is specifically related to a kind of for the anti-dropping soft ladder head in line maintenance.
Background technology
Transmission of electricity administrative institute of Qujing power supply administration administration line range is large, circuit distance is long, because topography and geomorphology is different with natural climate, often there is the displacement of stockbridge damper miscellaneous, lightning rod, conductor spacer in circuit, maintainer is when overhauling, and normally used is common rope ladder head, because the working time is longer, and comparatively large by the impact of environmental factor, maintainer's existence falls risk from rope ladder head, once occur falling, if maintainer cannot save oneself, then can need to be in suspension status for a long time.In actual track, wire has certain radian, current full body harness, and when people is in the unsettled and state tilted to a direction, comparatively large to waist force, the long time of suing and labouring can cause the problems such as waist is impaired, expiratory dyspnea.When ground staff sues and labours, special messenger also must be established to lift by crane maintainer, and kept state until transfer to ground, this link requires high to rescuer's arm strength, has the potential risk causing falling of accidentally dropping.
Summary of the invention
The utility model is just in order to overcome the defect and a kind of anti-dropping soft ladder head of designing that above-mentioned prior art exists.
The anti-rope ladder head device that directly falls of current development, maintainer can be shortened and fall distance, make maintainer as far as possible near rope ladder head device, due to the employing of anti-dropping soft ladder head unit is utilize self gravitation that slip rod member is pressed down locked safety rope, when maintainer saves oneself, as long as slip rod member is not suppressed by gravity, automatically safety rope will be discharged, now ground staff and cooperation maintainer, the rope risen by weight on hanging wheel tightens up, there is provided a lift upwards to maintainer, greatly will improve success rate of saving oneself.If save oneself unsuccessfully, then by ground staff, maintainer is retracted steel tower cross-arm, completed by personnel on tower and sue and labour, or transfer on the spot to ground.So the development of anti-dropping soft ladder head unit can be shortened rescue time, be improved achievement power of saving oneself, and reduces force requirements and the potential danger of ground staff simultaneously.
The utility model is achieved by the following technical solution:
A kind of anti-dropping soft ladder head, comprises rope ladder head, assembly pulley, the falling proof device being connected to rope ladder head side and the weight that is connected to rope ladder head opposite side plays hanging wheel, it is characterized in that:
