In work about electric power, livewire work, is the uninterrupted operation carrying out electrification in high voltage circuit and equipment.Livewire work Enforcement, it is possible to reduce the fault outage time, improve power supply reliability, improve power supply quality.Therefore, livewire work becomes For important operation means indispensable in distribution maintenance, repairing.
Livewire work mode, according to the difference of human-body potential, can be divided into equipotential live line work, medial potential working, earth potential Three kinds of modes of operation.Wherein, according to electric pressure and the difference of priority of protection, power distribution live-wire uses intermediate potential With two kinds of operation forms of earth potential.
At present, intermediate potential mainly uses the working system utilizing aerial lift device with insulated arm or insulated platform.Owing to vehicle is made Valency, size, applicable elements etc. limit, and the scope of medial potential working method and environment are required to higher, are unfavorable for further genralrlization Livewire work.And earth potential working method is to use climbers step on bar and utilize the mode of insulating bar operation.It has simple to operate, limit The features such as condition processed is few, applied range.Therefore, the popularization of earth potential working method will become the development side of livewire work from now on To.
In distribution line, cross-arm mainly uses single cross-arm and double two kinds of forms of cross arm device.And most earth potential live Initial line operation is carried out on double cross-arm electric poles;As it is shown in figure 1, described double cross-arm electric poles include electric pole 3, pass through bearing diagonal 2 support and are fixed on the electric pole 3 double cross-arms 1 close to top.Lead frequently with insulating block coordinated insulation endless rope or the lifting of single rope Line, tool for transmitting material etc..
But, conventional pulley wheel needs to be arranged on cross-arm, cross-arm thus install, remove time operating personnel will step on bar to relatively High altitude, thus cause operating personnel to reduce with the safe distance of electrical body and grounding body, it is difficult to ensure job safety, reduce Working performance.
Therefore it provides a kind of cross arm device that can utilize in existing distribution line carries out less important work, it is greatly improved Operational security and the auxiliary device of efficiency, be a good problem to study.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, this utility model provides a kind of easy to use, reliable, it is possible to have Effect ensures operating personnel and electrical body and the safe distance of grounding body, is effectively improved charged initial line, the work of transmission Work tool simultaneously The earth potential Special circulation rope support device of industry efficiency.
The purpose of this utility model is achieved in that
Power distribution live-wire earth potential Special circulation rope support device, including support bar 4, the middle part of support bar 4 is by insulation The top of insulating bar 7 is fixed by shank of bolt fastening bolt group b with support bar 4;Described insulating bar 7 is near 4 times square tubes of support bar Cross pulley fastening bolt group c and be fixed with pulley 5, pulley 5 is installed with combined cyclic rope;
Described combined cyclic rope includes insulate single rope 6 and insulation endless rope 8;
Described support bar 4 structure in T shape, is provided with the downward grab of level 9 at horizontal direction two ends;Described props up Strut 4 uses side by side for double-rod, by support bar fastening bolt group a, insulated bolt bar fastening bolt group b and pulley fastening bolt Group c fixes;
The described fastening bolt in pulley fastening bolt group c sequentially passes through insulating bar 7 and the support bar 4 being arranged side by side, Pulley 5 is arranged in the middle of the support bar 4 that is arranged side by side, and in wear the fastening bolt in pulley fastening bolt group c.
Actively beneficial effect: this utility model simple in construction, easy for operation, reliable, it is possible to operation people is effectively ensured Member and electrical body and the safe distance of grounding body, be effectively improved charged initial line, the working performance of transmission Work tool simultaneously.
