Description
Technical field
The present invention relates to a kind ofly utilize on the shaft tower existing overhead transmission line to lay the method for lines such as high voltage transmission line, cable, optical cable and the device of implementing this method in addition.
Background technology
In the payingoff construction that carries out overhead transmission line, commonly used is artificial construction's method at present, promptly in the lambda line job site of circuit, after with instrument institute's unwrapping wire being winched to the shaft tower top ends, again loop line is put to ground and be pulled to another shaft tower place by manually pulling, winch to the cat head end by instrument again, adopt tensioning apparatus that line is stretching then.As in the payingoff construction process, running into architectural barriers thing etc., then need build coil holder more temporarily, institute's unwrapping wire, cable are cleared the jumps; Then must make institute's unwrapping wire, cable cross the waters as lake, river with special-purpose means of transportation; As complicated topography and geomorphology, then the problem of being run into is just more, and construction is difficulty more, so that the payingoff construction of overhead transmission line exists labor intensity is big always, and ineffective present situation.
For addressing the above problem, once the someone adopted the directional transmissions method to carry out payingoff construction, promptly the Darts of cotton rope will be had in the transmitting tube by shell, the starting point of setting up from line, cable is emitted to the destination that line, cable set up, though this method is feasible, and the use cost height, and it is wayward, the guiding rope and the bigger occasion of target zone that can only be used for very light in weight have certain limitation so use, and are difficult to satisfy the needs of construction.
Also having a kind of method is to adopt the telecontrolled model helicopter to carry out payingoff construction, realize the unwrapping wire operation by telecontrolled model machine travel line, cable, though the telecontrolled model function is advanced fast, vertical takeoff and landing (VTOL), do not need advantages such as special airport, runway, but also only be applicable to line, the rope of placing some very light in weight, and can not directly pull line, the cable of constant weight, and so use certain limitation is arranged also, be difficult to satisfy overhead transmission line payingoff construction needs.
Summary of the invention
The objective of the invention is, a kind of draw-gear that can roll and travel on existing overhead transmission line is provided, with this device along overhead transmission line by with the line that carries, cable or directly Dragging Line, cable, with the method for finishing payingoff construction and the device of this method of enforcement.
The technical scheme that realizes the object of the invention is: the draw-gear that will have power is placed on the existing overhead transmission line, by handling Digiplex, the draw-gear that is built-in with corresponding remote control actuator is travelled along the overhead transmission line rolling by the direct Dragging Line of instruction, cable or with self brought line, cable, finish the required exercises of unwrapping wire, realize the unwrapping wire operation.
Implement line-putting method equipment therefor of the present invention and comprise draw-gear and the Digiplex of forming by remote-control transmitting mechanism and remote control actuator, described draw-gear is made of the power, transmission device, remote control actuator and the suspension sheave that are installed on the casing, have at least more than one and suspension sheave that circumferential edge has an arcuate guide groove is bearing on the corresponding supporting arm, supporting arm is fixedlyed connected with casing, at least be connected with a suspension sheave by power-actuated transmission device, transmission device is bearing on casing and the supporting arm.
The invention provides a kind of new line-putting method, be about to have power, the draw-gear that travels that can roll hangs on the existing overhead transmission line by suspension sheave, control the remote control actuator that is contained in the draw-gear by Digiplex, finish startup required in the payingoff construction, advance, retreat, exercises such as parking and acceleration and deceleration, increase substantially the operating efficiency of payingoff construction, also reduce labour intensity greatly with the while, because this method is not placed restrictions on by landform, it is easy to use and have working method flexibly, is applicable to various power transmission lines, cable, the payingoff construction of optical cable.
