Description
Technical field:
The present invention relates to and a kind ofly portablely the transmission line of electricity of one man operation can walk the special rope ladder of ray examination, be widely used in the work of upper and lower composite insulator in maintenance of overhead transmission line process, belong to transmission of electricity Overhaul site technical field.
Background technology:
Overhead transmission line mainly contains the compositions such as shaft tower, basis, wire, lightning conducter, insulator, gold utensil and ground device.Insulator mainly serves the effect supporting or hang wire in overhead transmission line, makes wire and shaft tower insulate simultaneously.
Due to the effect of bending, torsional load, compressive load and alternation mechanical load may be born and make the change of insulator generation performance, even there is phenomenon of rupture in the insulator in actual motion.Therefore, clear stipulaties in State Grid Corporation of China's 18 great anti-accident measures of electrical network: should avoid damaging full skirt, sheath and end part seal when composite insulator installation and upkeep operation, must not composite insulator be ridden.
Walk in ray examination work at the circuit of reality, the subject matter faced is that an operating personnel cannot after complete independently rolls off the production line work from a base shaft tower, on cross-arm from an other base shaft tower handled by itself ladder.Carry out walking ray examination defect elimination for 220kV overhead transmission line, the composite insulator that 220kV overhead transmission line straight line pole uses is generally about 2.4 meters, calculate the length connecting gold utensil up and down, operating personnel is approximately about 3.0 meters from cross-arm to the overall height on wire.When carrying out work under operating personnel needs to wire, often need two people or many people operation.First shaft tower is climbed by two operating personnels, when arriving cross-arm place, by pulley, the rope carried with, hanging ladder used for lower insulator is delivered on tower, hanging ladder is fixed on after on cross-arm, operating personnel by hanging ladder roll off the production line carry out aerial condutor walk the work of ray examination defect elimination, another operating personnel is delivered to ground with rope, then tower under this operating personnel after being removed by hanging ladder.The operating personnel of lower tower needs the shaft tower arriving on-line operation personnel power cut-off, then climbs upper tower and carry out same operation, help on-line operation personnel can utilize hanging ladder from wire on cross-arm, then 2 people one remove tower, terminate service work.As can be seen from said process, the hanging ladder that insulator uses up and down now needs multiple people cooperation to finish the work, and operation is more loaded down with trivial details, and required cooperation personnel are more.
Summary of the invention:
The object of the invention is to overcome above-mentioned prior art deficiency and provide a kind of structure simple, easy to operate, be easy to carry, save labour turnover, that increases work efficiency portablely the transmission line of electricity of one man operation can walk the special rope ladder of ray examination.
Object of the present invention can be reached by following measure: a kind ofly portablely the transmission line of electricity of one man operation can walk the special rope ladder of ray examination, it is characterized in that it is primarily of rising to the bait, turnbuckle, telescopic sleeve pipe, aluminium hydraulic pressed connecting pipe, wire rope, pedal, flower basket bolt, lower hook composition, to rise to the bait connection turnbuckle, turnbuckle connects telescopic sleeve pipe by wire rope, telescopic sleeve pipe connects at least one group of pedal unit by wire rope, one group of pedal unit bottom connects flower basket bolt, flower basket bolt connects lower hook, often organize pedal unit by a pedal, two aluminium hydraulic pressed connecting pipes, one section of wire rope is formed, each pedal two ends all connect an aluminium hydraulic pressed connecting pipe, pedal is connected with wire rope by aluminium hydraulic pressed connecting pipe.
In order to realize object of the present invention further, described pedal unit has four groups.
In order to realize object of the present invention further, described turnbuckle is primarily of connecting bolt, brake valve, spragging gear, fastening bolt, swing handle, wire stretching wheel, central axis, wheel carrier composition, the upper end of wheel carrier is provided with connecting bolt, wheel carrier connects brake valve by fastening bolt, and brake valve connects spragging gear, and wheel carrier connects central axis, central axis is provided with wire stretching wheel, one end connection of rotating handle of central axis, connecting bolt is connected with rising to the bait, and wire rope is fixed on wire stretching wheel.
In order to realize object of the present invention further, described flower basket bolt comprises adjusting rod, and the both sides of adjusting rod are respectively threaded a pull bar, and the hand of spiral of adjusting rod both sides cap nut is contrary.
The present invention can produce following good effect compared with the prior art: structure of the present invention is simple, be easy to carry, can one man operation be realized, effectively solve the problem that operating personnel needs many people to coordinate from the upper and lower insulator of different shaft tower, save cost of labor, substantially increase operating efficiency.It has:
1. structure is simple, easy to operate.The present invention primarily of rising to the bait, the composition such as turnbuckle, decorative pattern bolt, wire rope, telescopic sleeve pipe, pedal.Turnbuckle, decorative pattern screw are used for regulating the length of wire rope, adapt to the length of different model insulator and tighten up rope ladder; Telescopic sleeve pipe adopts fishing rod type scalable design, uses when installing and removing this rope ladder voluntarily for operating personnel.The mechanical composition of whole invention is fairly simple, easy for operation.
2. volume little, be easy to carry.Because whole invention connects to form primarily of wire rope, wire rope can effectively tighten up by turnbuckle, decorative pattern bolt, telescopic sleeve pipe can shrink to be deposited, make the small volume of whole invention, when operating personnel needs to be shifted on wire, only needs are placed in carry-on kit after this invention being tightened up and carry, and are beneficial to and work on wire.
3. reduce cost of labor.Many for needs people's cooperations are completed work by maximum feature of the present invention exactly, can only have been come by a people by application of the present invention.When this invention is fixed on shaft tower by operating personnel, operating personnel under a cross-arm after wire, by operation flower basket bolt and telescopic sleeve pipe, oneself will be risen to the bait and take off; When operating personnel's power cut-off from wire to another cross-arm time, utilize flower basket bolt and telescopic tube to be suspended on cross-arm by upper hook, Self-operating, greatly reduces cost of labor, improves operating efficiency.
