Method for paying-off by utilizing overhead line and equipment for implementing said method

Abstract

The present invention relates to a method to utilize the overhead line existed on the pole tower to place the line rope of high voltage transmission line, cable, optical cable and etc. and its executing device. the method is top place a draught attachment with motive power on the overhead line to use radio remote controlelr to start the draught attachment with a built-in remote control correspondance executing mechanism to carry out dragging work of line, cable or self brought line directly in rolling along the overhead line to fulfil various actions for placing the line rope to realize the line placing operation. The method will not be limited by the land form, so it can raise the efficiency of line placing operatino greatly and also reduce the intensity of work a lot, and so far it is ahigh efficiency constructino method of line placing among many line placing methods.

Description

technical field [0001] The invention relates to a method for additionally laying high-voltage transmission lines, cables, optical cables and other lines by using the existing overhead lines on the pole tower and a device for implementing the method. Background technique [0002] In the setting-out construction of overhead lines, the manual construction method is commonly used at present, that is, at the line-entry construction site, the set-out line is hoisted to the top of the tower with tools, and then the return line is placed on the ground and manually dragged. Pull it to another tower, then hoist it to the top of the tower with tools, and then use a tensioning device to straighten the line. If building obstacles are encountered during the setting-out construction process, it is necessary to temporarily build a cross-line frame to make the laid-off wires and cables pass over obstacles; The cable crosses the water area; if it encounters complex terrain and landforms, it ...

Problems solved by technology

If building obstacles are encountered during the setting-out construction process, it is necessary to temporarily build a cross-line frame to make the laid-off wires and cables pass over obstacles; The cable crosses the water area; if it encounters complex terrain and landforms, it will encounter more problems and the construction will be more difficult. Therefore, the setting-out construction of overhead lines has always been labor-intensive and low-efficiency.

[0003] In order to solve the above problems, someone once used the directional launching method for setting out construction, that is, the flying target with the wire rope in the launching tube was launched from the starting point of the wire and cable erection to the destination of the wire and cable erection by shells. Although it is feasible, the cost of use is high, and it is not easy to control. It can only be used for light-weight guide ropes and occasions where the target range is relatively large, so the use has certain limitations, and it is difficult to meet the needs of construction.

[0004] Another method is to use a remote-controlled model helicopter to carry out the setting-out construction, and the remote-controlled model machine pulls the wires and cables to realize the setting-out operation. Although the remote-controlled model machine can advance rapidly and take off and land vertically, it does not need special airports and runways. It is also only suitable for placing some light-weight wires and ropes, and cannot directly drag wires and cables of a certain weight, so the use also has certain limitations, and it is difficult to meet the needs of overhead line setting-out construction
