Referring to fig. 1, the present invention provides a cable protection pipe conveying mechanism, which includes two support frames 3 arranged in parallel; referring to fig. 2 again, a driving roller 32 is suspended from the top of the supporting frame 3, and two supporting rollers 33 are arranged at the bottom; the driving roller 32 and the two supporting rollers 33 form a space for clamping the protective tube body 200 together, and the driving roller 32 drives the protective tube body 200 to pass through the supporting frame 3; in order to balance the force applied to the protective tube body 200, the driving roller 32 is disposed on the perpendicular bisector of the two supporting rollers 33.

Referring to fig. 3, the driving roller 32 is also in transmission connection with a driving motor 35; the central axis of the driving roller 32 and the central axis of the protection tube body 200 form a predetermined included angle; the angle is preferably 10-15, such as 12, 13 or 14; the outer surface of the driving roller 32 is coated with a rubber layer, so that the driving roller has large friction force when being attached to the protection tube body 200. Due to the included angle, the friction force generated by the driving roller 32 on the protective tube body 200 has a component in the axial direction and the circumferential direction. Wherein the protection tube body 200 is driven to advance by the axially upward component force, and the protection tube body 200 is driven to rotate by the circumferentially upward component force. The protective tube body 200 is rotated and moved forward in the direction of the central axis thereof, and the conveyance jamming caused by the local deformation of the protective tube body 200 is avoided. The distance between the two supporting frames 3 can be set adaptively, so that the protection tube body 200 also has certain straightening and rounding effects in the conveying process.

Referring to fig. 4, the support rollers 33 are disposed on the support roller frame 36; the art can set the distance of the two sets of support roller stands 36 according to the actual diameter of the protective tube body 200. A plurality of universal balls 34 used for abutting against the protection tube body 200 are embedded in the surface of the supporting roller 33; the protective tube body 200 can smoothly complete the rotation and advance operation.

Preferably, the support frame 3 is disposed on the mobile vehicle 31 to facilitate movement at a construction site.

In order to prevent the long protective tube body 200 from being deformed during transportation. Preferably, a plurality of auxiliary roller frames 4 are respectively arranged on two sides of the moving vehicle 31; the auxiliary roller frame 4 is provided with an auxiliary roller 41 for supporting the protective tube body 200; a plurality of auxiliary rolling balls 42 are uniformly embedded on the outer surface of the auxiliary roller 41. The auxiliary rolling balls 42 hold the protective tube body 200 from bending deformation under gravity, while not hindering rotational advancement thereof.

Referring to fig. 6, the invention also provides a threading device with the mechanism, which comprises a spiral coil 2 arranged between two supporting frames 3 and movably sleeved outside a protective tube body 200; and two ends of the spiral coil 2 are electrically connected with the power box 21.

The wire drawing mechanism 100 is arranged in the protective tube body 200; the wire pulling mechanism 100 can be bolted with a pull rope and can do relative motion along the axial direction of the protection tube body 200; one end of the wire pulling mechanism 100 is bolted to the pull rope entering from one port of the protective tube body 200 and exiting from the other port, thereby threading the pull rope through the protective tube body 200. The other end of the pulling rope is bolted with the cable, and after the pulling rope is threaded in the protection tube body 200, the pulling rope is continuously pulled out from one end of the protection tube body 200, so that the cable is threaded into the protection tube body 200, and the threading of the cable in the protection tube body 200 is completed. The threading efficiency of cable has been improved.

Referring to fig. 7, the wire pulling mechanism 100 includes a string penetrating pipe 1, and two ends of the string penetrating pipe 1 are respectively provided with a roller assembly; a permanent magnet 11 sleeved outside the penetrating pipe column 1 is arranged between the two roller components; the permanent magnet 11 is preferably of cylindrical configuration; two ends of the string penetrating pipe 1 are respectively provided with a rope buckle 17 for bolting a pull rope.

With reference to fig. 8, the roller assembly includes at least three roller supports 14 uniformly arranged around the outer side of the tubular string 1; the end of each wheel strut 14 is provided with a universal wheel 15 for abutting on the protective tube body 200.

Preferably, the wheel support 14 is rotatably arranged outside the perforating string 1 through a support bearing 16; the universal wheel 15 can rotate around the penetrating pipe string 1 while moving in the axial direction of the protective pipe body 200. The slight bending, protrusion or deformation of the local position of the self-adaptive protection tube body 200 reduces the resistance of the wire pulling mechanism 100 to move.

Referring to fig. 9, as a preferred solution, the universal wheels 15 are disposed on the telescopic rods 151; a cavity which is movably sleeved with the telescopic rod 151 is arranged on the wheel strut 14; the bottom of the cavity is provided with an adjusting spring 153 for abutting against the telescopic rod 151; when the universal wheel 15 encounters a slight protrusion on the inner wall of the protective tube body 200, the telescopic rod 151 compresses the adjusting spring 153, thereby preventing the universal wheel 15 from being caught.

Further, a flange structure is arranged at an opening position of the cavity of the wheel strut 14, and a stop ring 152 corresponding to the flange structure is arranged on the telescopic rod 151. The telescopic rod 151 is prevented from coming out of the inner cavity of the wheel post 14 in a free state.

A direct current is introduced into the spiral coil 2, so that a magnetic pole is induced in the center of the spiral coil 2; the direction of the current is set so that the polarities of the ends of the spiral coil 2 opposite to the permanent magnet 11 are the same, for example, both N-poles or both S-poles. The permanent magnet 11 is substantially positionally invariant under the influence of magnetic repulsion. As the protective tube body 200 continuously moves through the support frame 3, the piercing post 1 moves relative to the protective tube body 200, thereby piercing the pulling rope into the tube.

The invention realizes the threading operation of the cable in the conveying process of the protective tube body 200. The conveying and threading procedures of the protection tube are integrally completed, so that the operation efficiency is greatly improved.

The permanent magnet 11 of the present invention is preferably made of neodymium magnet, and has strong magnetism and large repulsive force.

The invention induces a magnetic pole at the center position of the spiral coil 2 by using current, and pushes the permanent magnet 11 to move by using magnetic repulsion, thereby realizing non-contact driving. Simple structure and convenient operation.

Preferably, the penetrating pipe column 1 is movably sleeved with a sliding sleeve 12, and a permanent magnet 11 is fixedly sleeved on the outer side of the sliding sleeve 12; referring to fig. 10, a plurality of balls 121 abutting against the outer wall of the string penetrating pipe 1 are uniformly arranged on the inner wall of the slip sleeve 12. The permanent magnet 11 can rotate relative to the penetrating pipe column 1, and stress of the penetrating pipe column is balanced. When the direction of the magnetic repulsion force of the helical coil 2 is not coaxial or parallel to its magnetic axis, the permanent magnet 11 can be balanced by rotational adjustment, even converting this force into a driving force. The wire pulling mechanism 100 can move smoothly in the protective tube body 200.

Preferably, a soft cushion layer 13 is arranged between the sliding sleeve 12 and the permanent magnet 11, so that hard connection between the sliding sleeve and the permanent magnet is avoided. Preferably, the cushion layer 13 is a rubber layer to prevent relative rotation between the permanent magnet 11 and the slip sleeve 12.

In summary, the invention provides a cable protection pipe conveying mechanism, which comprises two supporting frames; a driving roller and a supporting roller are arranged in the supporting frame; the driving roller drives the protection tube body to rotate and then passes through the supporting frame; the conveying process of the protection tube is optimized, and meanwhile, certain straightening and rounding effects are achieved on the surface of the tube body. The invention also provides a threading device with the mechanism, the threading device is provided with a wire pulling mechanism which can move in the protective tube body, and a driving mechanism is arranged outside the protective tube body to drive the wire pulling mechanism to move; one end of the wire pulling mechanism is bolted with the pulling rope to enter from one port of the protecting tube body and to be led out from the other port, so that the pulling rope is threaded in the protecting tube body. The other end bolt of stay cord connects the cable, after the stay cord was worn in the protection tube body, will constantly pull out the stay cord from the one end of protection tube body to wear the cable to the protection tube body in. The threading operation of the cable is realized in the conveying process of the protective tube, and the construction efficiency is improved.
