Embodiment Construction
[0015] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0016] A cross-over wire structure, including pole 1, pole top seat 2, rope one 3, pulley 4, wire one 5, wire two 6, rope two 7 and rope three 8; the top of pole 1 is provided with a pole top Seat 2, one end of rope one 3 is fixed on the rod top seat 2, and the other end is connected to the hook of pulley 4; wire one 5 passes through pulley 4; wire two 6 is bound to the pole 1 below the pole top seat 2 through rope two 7 On; one end of rope three 8 is fixed on the lower end of pulley 4, and the other end is connected to the below of binding wire two on the electric pole.
[0017] The first wire is a newly erected wire on the upper layer, and the second wire is an original crossed wire on the lower layer.
[0018] A method for crossing and crossing lines, comprising the steps of:
[0019] The wire 2 6 was originally installed on the pole 1, a...

The invention relates to a cross-span wire-traversing method and a cross-span wire-traversing structure, and belongs to the span technical field of wire erection. According to the technical scheme, a pole top base (2) is arranged at the top end of an electric pole (1); one end of a rope I (3) is fixed on the pole top base (2) while the other end of the rope I is connected with a hook of a pulley (4); a wire I (5) passes through the pulley (4); a wire II (6) is bound on the electric pole (1) below the pole top base (2) through a rope II (7); and one end of a rope III (8) is fixed at the lower end of the pulley (4) while the other end of the rope III is connected below the wire II bound on the electric pole. The cross-span wire-traversing method and the cross-span wire-traversing structure have the beneficial effects that a cross-span wire-arranging operation can be done freely by using the cross-span wire-traversing structure in wire erections in the cross-span manner, without requiring to establish a span frame or without putting down the lower layer wires, so that time and labor force are saved, and safety risks are greatly lowered.
Description
technical field [0001] The invention relates to a method for crossing and crossing a wire and a structure for crossing and crossing a wire, and belongs to the technical field of wire spanning. Background technique [0002] When the construction of 35KV lines in mountainous areas of our country crosses power or communication lines of 10KV and below, it is usually used to complete the wiring task by taking a spanning frame. However, due to terrain restrictions, when it is impossible to cross over the bridge, the original line can only be dropped, and after the upper layer of the conductor is erected, the original crossed line can be re-erected. When the span of the crossed line is large and the tension section is long, the amount of work for re-releasing and erecting the conductors is quite large, the power outage time is long, and there are many safety hazards, which increase the construction difficulties. Contents of the invention [0003] The purpose of the present inven...
