The technical solution adopted in the present invention is: tower machine supply lines, is characterized in that: comprise interconnective external power cord and special supply lines, and for connecting the distribution box transition wire of special supply lines and distribution box; Described special supply lines is connected in sequence by some power supply line segments be fixed on tower-body standard section, adopts connector to removably connect between adjacent two power supply line segments.
Described connector comprises for connecting adjacent two power supply line segments to realize the conductive contact be electrically connected, and banding is enclosed within adjacent two power supply line segment junctions in case two power supply line segments are thrown off, surrounded conductive contact therein to realize the anchor ear of junction waterproof simultaneously, described anchor ear adopts insulating material to make.
Described power supply line segment comprises insulation epidermis, and be embeddedly fixed on this insulation meter intracutaneous and five of mutually insulated conductive metal sheets, in five conductive metal sheets three be live wire, one be zero line, one for ground wire, it is exposed that the two ends of each sheet metal all extend insulation epidermis outside; The adjacent two exposed sheet metals in power supply line segment ends are connected by conductive contact and realize electrical connection.
The cross section of described power supply line segment is square.
Described power supply line segment is fixed on tower-body standard section by the holder be installed on the horizontal web member of tower-body standard section.
The power supply line segment top be fixed on the standard knot of tower body top is provided with the waterproof lid that insulating material is made.
The exterior protection grade of described power supply line segment and lid is not less than IP44, and puncture voltage is not less than 20kv/min, and insulation resistance is greater than 10M Ω.
The exterior protection grade of described anchor ear is not less than IP44, and puncture voltage is not less than 20kv/min, and insulation resistance is greater than 10M Ω.
Beneficial effect of the present invention: because special supply lines is connected in sequence by some power supply line segments be fixed on tower-body standard section, connector is adopted to removably connect between adjacent two power supply line segments, therefore the present invention compared with prior art has the following advantages: 1, there is not the problem of increasing deadweight increase with tower body, reduce the wearing and tearing in use procedure, extend useful life, reduce use cost.2, arbitrarily can add and subtract with the height of tower body height, and can exchange use on same model tower machine, interchangeability is very strong.3, easy to maintenance, sectional checks special supply lines, if you have questions, changes a certain section of power supply line segment.4, cost is low, can use multiple architectural engineering continuously, need not change.5, can effectively prevent electric wire stolen.6, safe and reliable, outward appearance is beautiful.

Embodiment
As shown in Figure 1 and Figure 2, the present embodiment comprises interconnective external power cord 1 and special supply lines 2, and for connecting the distribution box transition wire 3 of special supply lines 2 and distribution box, namely external power cord 1 is connected to distribution box after special supply lines 2 and distribution box transition wire 3, powers to whole tower machine.Described special supply lines 2 is connected in sequence by some power supply line segments 4 be fixed on tower-body standard section 9, connector is adopted to removably connect between adjacent two power supply line segments 4, the wearing and tearing in use procedure can not only be reduced, increase the service life, reduce use cost, and arbitrarily can add and subtract with the height of tower body height, interchangeability is strong.
As shown in Figure 3, Figure 4, described connector comprises for connecting adjacent two power supply line segments 4 to realize the conductive contact 5 be electrically connected, and banding be enclosed within adjacent two power supply line segment 4 junctions anchor ear 6(adopt insulating material make), be used for preventing two power supply line segments 4 from throwing off on the one hand, on the other hand conductive contact 5 is surrounded therein to realize the water proof and dust proof of junction, improve the fail safe of outdoor use.As shown in Figure 6, Figure 7, the cross section of line segment of powering described in the present embodiment is rectangular, comprise insulation epidermis, and be embeddedly fixed on this insulation meter intracutaneous and five of mutually insulated conductive metal sheets 7, in five conductive metal sheets 7 three be live wire, one be zero line, one for ground wire, it is exposed that the two ends of each sheet metal 7 all extend insulation epidermis outside; The adjacent two exposed sheet metals in power supply line segment 4 ends 7 are connected by conductive contact 5 and realize electrical connection.
As shown in Figure 5, the horizontal web member 10 of described tower-body standard section 9 is provided with holder 8 by bolt or rivet, described power supply line segment 4 is fixed on tower-body standard section 9 by this holder.
For preventing from leaking or foreign matter enters special supply lines 2, power supply line segment 4 top be fixed on tower body top standard knot 9 is provided with the waterproof lid that insulating material is made.
The exterior protection grade of described power supply line segment 4, lid and anchor ear 6 is not less than IP44, and puncture voltage is not less than 20kv/min, and insulation resistance is greater than 10M Ω.
Tower machine lifting guide support adding or when falling joint, predetermined supernumerary segment or fall joint location criteria joint 9 special supply lines 2 be connected with tower machine distribution box by distribution box transition wire 3, now distribution box transition wire 3 lays outside jacking stock 11, through undersetting 12 bottom undersetting 12, get involved after upper bracket 13 on distribution box, hydraulic jack power line on jacking stock 11 is received on tower machine distribution box in the same fashion, switch on power and start jacking or fall joint, after reaching certain height, remove the connection of distribution box transition wire 3 and special supply lines 2, the special supply lines 2 between standard knot 9 is connected again by anchor ear 6 and conductive contact 5, again distribution box transition wire 3 is connected, repetition jacking adds falls joint action, until complete the final height of tower body.The length of distribution box transition wire 3 is about the length of 7 times of standard knots 9, and this length is for convenience of can jacking more standard joint 9 and reserving.During each dismounting distribution box transition wire 3 again, special messenger is needed to cut off power supply on ground.
