The main power wheels can be used by the two groups of outer pulley supporting pieces of the pipe according to the field condition, and the main power wheels and the auxiliary power wheels can be exchanged in the use process so as to avoid the operation of workers from going back and forth to the two ends of the cable trench.
The threading pipe 3 is formed by connecting a plurality of sections of single sleeve pipes 30 in a detachable mode end to end mode, clamping seats 31 for installing the pulley 5 in the pipe are respectively arranged on the inner walls of the two end portions of each section of single sleeve pipe 30, and the two clamping seats 31 are located on the inner walls of the same side of the single sleeve pipe and correspond to each other.

In the working state, the two groups of outer pulley supporting pieces 1 are respectively positioned above the two end parts of the threading pipe 3; at least two ends of the threading pipe 3 are respectively provided with an in-pipe pulley 5, and the in-pipe pulley 5 is connected with a clamping seat 31 at the outer end of the single sleeve at the end part of the threading pipe 3 in a clamping way through a bracket; if the cable trench is longer, the pulley in the tube can be arranged on the clamping seat of the middle section single sleeve according to the situation; the hauling rope 2 passes through the threading pipe 3 and sequentially winds around each inner pipe pulley 5 and the supporting pulleys 10 of the two groups of outer pipe pulley supporting pieces, and two ends of the hauling rope are mutually connected to form a closed ring shape.
When the threading pipe penetrates into the cable trench, the cone cover 4 is arranged at the outer end (free end) of the single sleeve at one end of the threading pipe 3 and the joint is kept smooth, so that the threading pipe can conveniently enter the cable trench.
As an optimization scheme, the threading pipe 3 adopts a taper pipe (a straight pipe can be adopted when a cable trench is narrower), namely the diameters of the single sleeves 30 of the multiple sections of the taper pipes are gradually increased, the taper cover 4 is connected with the single sleeves at the small diameter end of the threading pipe 3, and the threading space in the trench can be gradually expanded by the design, so that the difficulty in threading is further reduced.
As another optimization scheme, the bracket of the pulley 5 in the pipe is obliquely supported, and after the pulley 5 in the pipe is clamped with the threading pipe 3, the outer edge of the pulley is positioned outside ports (free ends of the single sleeve) at two ends of the threading pipe; the supporting pulley 10 of the pulley support piece 1 outside the pipe extends outwards obliquely from the vertex angle of the supporting seat, so that the supporting pulley 10 extends out, and friction between a traction rope and a threading pipe port, the supporting seat or a foundation is avoided.

The right-angle clamping position of the supporting seat 11 is utilized to be clamped and supported with the ground 60 (a trench cover plate or a vertical shaft edge) above the port of the threading pipe, the external pipe pulley supporting piece 1 (the supporting pulley 10) is arranged right above the two ports of the threading pipe, then the traction rope 2 is disassembled, the traction rope sequentially winds around the internal pipe pulleys 5 and the supporting pulleys 10 of the two groups of external pipe pulley supporting pieces, and two ends of the traction rope are mutually connected to form a closed ring.
Finally, the end part of a cable (wire harness) to be grooved is inserted into the threading pipe 3 and is hung on a traction rope, a supporting pulley 10 serving as a main power wheel is driven to drive the cable to pass through the threading pipe, and the threading pipe is used for isolating new and old cables in the process, so that the cables are prevented from being mutually rubbed and damaged during threading; in addition, the cable can be hung and hoisted on the traction rope section by section to avoid friction between the cable and the inner wall of the threading pipe. And removing the device after the operation is finished.
Example 2
As can be seen from fig. 3, the difference between the present embodiment and embodiment 1 is that each section of the single sleeve 30 of the threading pipe 3 is formed by joining two arc plates, that is, the single sleeve 30 is divided into an upper arc plate 301 and a lower arc plate 302 along the central line direction, one side of the upper arc plate 301 and one side of the lower arc plate 302 are hinged by adopting a hinge, and the other side is connected by a buckle 32 to form an openable structure, so as to facilitate the disassembly and assembly of the threading pipe 3 in construction.

The structure design makes the assembly and the disassembly of the threading pipe 3 more convenient, the process of threading the cable trench is not influenced by the length of the cable outside the cable trench, and the pulling traction rope can be pulled to circularly run to continuously convey longer cables without influencing the disassembly and assembly of the single sleeve 30.
Other technical features of this embodiment are the same as those of embodiment 1.
Finally, it should be noted that: the above examples are intended to illustrate the technical solution of the present invention, but not to limit it, and those skilled in the art may modify the embodiments or make equivalent substitutions for some technical features without departing from the spirit of the technical solution of the present invention, and all the embodiments are included in the scope of the present invention as claimed.
