Embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides the non-excavation power cable laying of a kind of guiding traction method, comprise the steps: that at first, at the well head place of the first cable shaft 26 installing cables dish 2, the cable 1 be arranged on cable hank 2 send cable machine 8 by after the one or three the two-sided carrying roller 4 of carrying roller 3, first, the 6, the 23 carrying roller 7 of the two-sided carrying roller of single mount roller 5, second, being transported to first successively.The two-sided carrying roller 6 of described single mount roller 5, second and the two or three carrying roller 7 are arranged on cable trough by the first plane steelframe 10.Described first send cable machine 8 to be arranged on cable trough by the steel mounting 9 tilted, and cable 1 is by the first underground pillar 14 of input that send cable machine 8 to tilt, and the cable 1 of sending into is 15o with the angle of the face of underground horizontal.
Then first send cable machine 8 that cable 1 is transported to intermediate cable well 27 by underground pillar 14, the intermediate cable well is transported to the second cable shaft 28 by cable 1 by underground pillar 14.The carrying roller 11 and second of wheel more than first is installed in described intermediate cable well 27 and send cable machine 12, described intermediate cable Jing27Kou is equipped with the second plane steelframe 13, and described more than first wheel carrying rollers 11 and second send cable machine 12 to be arranged on the second plane steelframe 13 by the rope made of hemp.
The well head place of the second cable shaft 28 is equipped with hoist engine 20, and the haulage cable 21 be arranged on hoist engine 20 is connected with an end of trailer system, and the cable 1 that is transported to the second cable shaft is connected with the other end of trailer system by more than second wheel carrying rollers 15.Described trailer system comprises anti-twister 19, tensioner 18, cable drawing head 17, and described tensioner 18 is connected with anti-twister 19, cable drawing head 17 respectively; Described anti-twister 19 is connected with haulage cable 21, and described cable drawing head 17 is connected with cable 1.Described more than second wheel carrying rollers 15 are arranged on cable trough by the 3rd plane steelframe 16.Cable drawing head 17, by making in cables manufacturing factory, has water resistance.Tensioner 18 has the wireless transmission signal function.
The power cable non-excavation that leads lays the more region that river crossing, railway, highway etc. can not excavate trench that is used in.By the restriction of cables manufacturing transportation condition, the cable joint length is in 1000m, so make the well that continues that cable is set when position after cable penetration, or increase by 1 intermediate cable well in the middle of two end connector well, can increase the number of intermediate cable well according to the length of traverse distance.Near the vehicle pass-through Jing Yichu that continues of cable easily, installing cables dish 2 is set.During the intermediate cable well arranges, cable 1 curve transition is played in the settings of many wheel carrying rollers 11, second send cable machine 12 tilt with underground pillar 14 axis one to.
As shown in Figure 2, an end of described the first cable shaft is equipped with total generator 22, and described total generator 22 is connected with the first generator 23, the second generator 24, the 3rd generator 25 respectively, and described the first generator 23 send the motor of cable machine 8 to be connected with first; Described the second generator 24 send the motor of cable machine 12 to be connected with second, and described the 3rd generator 25 is connected with the motor of hoist engine 20.
The non-excavation power cable laying of the described a kind of guiding of the present embodiment traction method is when traction, and cable first draws top root, and then successive is downward, finally draws bottom root.Cable protecting tube 14 is interior can fill water, to reduce cable 1, drags resistance.Often changing a cable 1 send cable machine and many wheel carrying rollers to adjust position.Cable discharges by the special messenger commander issues an order, and each work-yard is equipped with the machine of begging for.Wire-feeding machine and hoisting machine 20 rotate simultaneously or stop transport, and Wire-feeding machine has at the uniform velocity constant force spy to give birth to, the steady application of force balance of hoisting machine 20 take-up speed.Bending when power cable is subject to larger axis to pulling force, to itself injury power maximum, in the bending of suffered pulling force larger part, select many wheel carrying rollers, and the cable size of amassing wealth by heavy taxation with the curved radius 20 of arc because of the wheels of taking turns carrying rollers, effectively cable bending transition more.
The non-excavation power cable laying of the described a kind of guiding of the present embodiment traction method, its rational facility are selected and electrical source of power is arranged, can effectively solve the traction technique problem of the non-excavation power cable laying of long distance, and traction technique is safe and reliable, harmless for trailing cable.
