Abstract
The invention discloses an obstacle bridging construction method for power line wiring and wiring pulleys. The method is convenient and quick to construct, small in labor number and high in universality. The method sequentially includes: laying three pulling ropes and a front dragline, enabling the tree pulling ropes to respectively penetrate through at least one pulley block at one ends of towers, pulling the pulling rope in a main pulley to enable a middle guide line to go through from one tower to another tower under the suspension of the other two pulling ropes and auxiliary pulleys, pulling the pulling rope in the two auxiliary pulleys to enable two side guide lines to go through from one tower to another tower under the suspension of the auxiliary pulleys, and recovering the pulley block to finish wiring works of enabling the guide lines to pass through the obstacles. The whole wiring process is performed on the two towers, each guide line is suspended through the pulling ropes without contacting with the ground and free of control by people standing below, so that damages to ground crops and blockage to traffic lines below the guide lines are avoided.
Description
Technical field
The present invention relates in the electric power system a kind of method and the stringing of stringing and use coaster, more specifically to a kind of power circuit stringing leaping over obstacles construction method and wires-erecting pulley.
Background technology
In the overhead transmission line process of deployment of power circuit, often need the across obstacle stringing sometimes, like other circuit, highway, railway, bridge, river, tall and big plant woods, cropland etc. (general designation is crossed over thing); Restrictions such as often receiving object being spanned height, width, geographical position is set up in this leap; The leap operation is complicated, and workload and difficulty are big, and interruption duration is long; Big to the influence on ground, as to need road or navigation channel envelope road causes damages, problem such as dispute takes place to claim damages the vegetation on ground.Have a strong impact on the progress and the efficient of stringing, and whole stringing hand labor intensity is big.Though have at present 200810234611.7 overhead transmission lines to cross over the patent of stringing method and wires-erecting pulley, this method can only be set up by the single line single line, and when stringing, need the people on ground with steel wire rope 4 pulling wires-erecting pulley 1; Height with control wires-erecting pulley 1 upper conductor 8; The somebody must hold on ground and move and be connected the stay cord 6 on the coaster 1 simultaneously, reaches the purpose that moves forward and backward coaster 1, and preferably the somebody holds and moves and is connected the location drag-line 5 on the coaster 1; Each movable block 1 needs 3 people (at least 2 people) after this manner; If the construction of line of crossing over is long, intermediate demand 5-6 platform movable block 1 even longer just needs more people.Though such stringing method lead can unsettledly set up, many people also must stand under the lead rely on various ropes with about the control coaster 1, seesaw etc.This can only solve lead 8 and not land, and for lead be for 8 times highway, railway, lake, water surface navigation channel must seal, could the stringing construction after iceound.Therefore this method still receives the restriction of many environment and geographic factor, and numerous workmans' manipulation and cooperation need be arranged on ground, and the stringing cost is very high, and efficient is also low.
Summary of the invention
The purpose of this invention is to provide a kind of easy construction, quick, the recruitment number is few, the power circuit stringing leaping over obstacles construction method and the wires-erecting pulley of highly versatile.
In order to solve the problems of the technologies described above, this power circuit stringing leaping over obstacles construction method is successively:
(1) between two shaft towers of need route wires, put three pull ropes and a fore stay earlier, and be fixed between two A and the B shaft tower, the tail end of every pull rope connects middle lead and two limit leads that three needs are laid respectively;
(2) three pull ropes pass at least one tackle pulley respectively at an end of shaft tower; Each tackle pulley has a main coaster and two branch coasters, and two branch coasters wherein are connected with main coaster through connection cord, and fore stay is connected with first tackle pulley; Be connected in series through static line between the tackle pulley before and after each; In the end be fixed with backstay on a tackle pulley,, adjust centre and the overhead positions of each tackle pulley between two shaft towers through the traction of fore stay and backstay;
(3) pull rope in the tractive master coaster; With connecting middle lead behind this pull rope at all the other two pull ropes and divide under the suspention of coaster aloft from a shaft tower to another shaft tower; Should be strained and fixed on two shaft towers by middle lead then, lead is mentioned in all tackle pulley quilts;
(4) pull rope in two branch coasters of tractive, with two limit leads under the suspention of minute coaster aloft from a shaft tower to another shaft tower, accomplish three leads and set up vacantly between two shaft towers;
(5) tractive fore stay or backstay make each tackle pulley to an end of shaft tower, and what shed tackle pulley and middle lead and limit lead is connected the stringing work of completion lead leaping over obstacles.
The length of said static line is 30-40 rice.
Main coaster described in the above-mentioned power circuit stringing leaping over obstacles construction method be a fourfold block it include 4 pulleys that become each two arrangement of two rows; Each pulley is connected with the large pulley framework through bearing pin; Side at the large pulley framework is shaped on big overhead door through big hinge; The other end of big overhead door is connected with the large pulley framework through bearing pin; The lateral surface of big overhead door and with the large pulley framework of big overhead door relative position on be fixed with the connecting rod of opening respectively, form the looping pit that supplies connection cord to connect, on guide roller frame, be provided with the connecting hole that supplies static line to connect.
In looping pit, be with connecting ring, connection cord is connected with connecting rod through connecting ring again.
Described connecting hole is that be welded with fixed lever in the lower end of large pulley framework formed.
Branch coaster described in the above-mentioned power circuit stringing leaping over obstacles construction method is a three-fold block; It includes the truckle framework and on the truckle framework, sells and be fixed with three pulleys that are triangularly arranged; Side at the truckle framework is shaped on little overhead door through small hinge; The other end of little overhead door is connected with the truckle framework through pin, on the truckle framework, is shaped on the connecting ring that supplies fixed connection string.
Described pulley is processed with nylon material.
Power circuit stringing leaping over obstacles construction method and wires-erecting pulley according to such scheme enforcement; All on two shaft towers, carry out in whole stringing process; Each lead is not contacted with ground by pull rope, middle lead and the unsettled picking-up of special-purpose coaster in the process of traction; Do not need the people yet and control below, can not cause the injury of surface crops under the lead and the obstruction of traffic route.Whole stringing process operation is simple, and safety can not cause damage to surrounding environment, does not also receive the restriction of geographical conditions.The wires-erecting pulley structure and the manufacturing process that are designed are simple, use reliably, and convenient, especially main coaster adopts fourfold block, and whole tackle pulley is moved steadily.The loss that this scheme can be brought for laying, repairing shortening time and the minimizing construction of power circuit.
