The two bearing ropes 4 are respectively connected to the first connecting block 31 and the second connecting block 32. One end of the bearing rope 4 is fixed on the connecting block 3, the other end of the bearing rope is clamped on the other adjacent connecting block 3, and the bearing column 5 is placed on the two bearing ropes 4. Second joint groove 35 has all been seted up on first connecting block 31 and the second connecting block 32, and logical groove 36 has been seted up in second joint groove 35 department to first connecting block 31 and second connecting block 32, and bearing rope 4 and connecting block 31's joint end fixedly connected with fixture block 41, fixture block 41 card are established in second joint groove 35. The fixture block 41 is provided with a second semicircular hole 411, and the two second semicircular holes 411 form a through hole for the connection rope 6 to pass through in a combined manner, so that the fixture block 41 is prevented from interfering with the connection rope 6 during installation. During the use, fixture block 41 card of two bearing ropes 4 among the first group of bearing device is gone into in the connecting block 3 of the second group of bearing device, after the cable was put on the heel post 5, because the weight of heel post 5 self and cable weight, make bearing rope 4 atress drop down, and then make first connecting block 31 and second connect 32 and be in inseparable lock state always, and then will connect the inseparable interlock of fixture block 41 of rope 6 between first connecting block 31 and second connecting block 32, prevent that fixture block 41 from droing, realize bearing rope 4 and connecting block 3's being connected.
The both ends of heel post 5 all are equipped with joint platform 51, and first joint groove 511 has been seted up to joint platform 51 bottom, the first stopper 42 of intermediate position fixedly connected with of bearing rope 4, during the use, place heel post 5 on bearing rope 4, first stopper 42 card is gone into in first joint groove 511, because the cable weight of placing on the weight of heel post 5 self and the heel post 5, makes heel post 5 and bearing rope 4 joint firm.
The cover is equipped with a plurality of sleeves 52 on the heel post 5, after the cable head was pulled to the other end from the one end of body 1, when the cable pulling of follow-up not passing the protection tube completely, will remove on sleeve 52 on heel post 5, and frictional force is little, makes the quick completion of cable wear to establish. The distance between two adjacent sleeves 52 should be smaller than the diameter of a single cable to prevent the cable from getting caught between two adjacent sleeves 52.
The power cable protection tube of swift threading of this embodiment, when wearing to establish the cable, at first two sets of slider of one end installation and load bearing device of body 1, the fixture block 41 card of load bearing rope 4 among the first set of load bearing device goes into the second joint groove 35 of connecting block 3 among the second set of load bearing device, the first joint groove 511 card at 5 both ends of heel post is established on the first stopper 42 of load bearing rope 4 intermediate position, connect rope 6 and put into first connecting block 31 and second connecting block 32 in first semicircle hole 34, and two second stoppers 62 are located first connecting block 31 and second connecting block 32 both sides.
Fix the end of penetrating of cable and bind on heel post 5, connect rope 6 through the haulage rope pulling of wearing to establish in the protective tube in advance and remove, drive slider and bearing device and cable and remove to body 1. The subsequent slide and load bearing device installation method is the same as the above steps, but the cables in the subsequent load bearing device do not need to be tied to the load bearing post 5.
After the penetrating end of the cable is pulled to the other end from one end of the protection tube, the penetrating end of the cable is removed from being bound with the bearing column 5, the connection between the pulling rope and the connecting rope 6 is removed, the pulling rope and the penetrating end of the cable are bound firmly, the two ends of the connecting rope 6 are fixed, the connecting rope 6 is prevented from continuously moving, then the pulling rope is continuously pulled, and the cable which does not penetrate through the protection tube is continuously penetrated into the protection tube. When the traction rope pulls the cable at this stage, the cable moves on the sleeve 52 on the bearing column 5, and the friction force is small, so that the cable can be quickly threaded.
After the cable is worn to establish, will connect the fixed of 6 both ends of rope and remove, rope 6 is connected in the pulling, pulls out slider and load-carrying device in the protective tube to cycle use next time.
