Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A cable threading device and a threading method, as shown in figure 1. The cable threading device comprises a pipe body 1, wherein the right end of the pipe body 1 is communicated with a conical sleeve 2 which can be adapted in the threading pipe, the diameter of the inner wall of the conical sleeve 2 is consistent with that of a cable, the annular area of the conical sleeve 2 is gradually increased rightwards, a gap is formed in the conical sleeve 2, the gap extends towards the left end surface of the conical sleeve 2 along the right end surface of the conical sleeve 2, and the gaps are uniformly distributed along the circumferential direction of the conical sleeve 2; the cover has ring 3 on the toper sleeve 2, and ring 3 includes first semicircle ring 31 and lower semicircle ring 32, the outside fixedly connected with intermediate lamella of opposite face of first semicircle ring 31 yu xian 32 passes through bolt fixed connection between the double-phase opposite intermediate lamella, and the horizontal fixedly connected with of right flank of ring 3 has along the connecting rod 5 of 3 center line symmetries of ring, and connecting rod 5 has seted up the external screw thread towards the one end of connecting plate 6 and has cup jointed stopper 8, sets up the through-hole that connecting rod 5 passed on the connecting plate 6, and the end threaded connection that wears out the through-hole of connecting rod 5 has gland nut 9.
This device is when using, at first will go up ring 3 and lower ring 3 to detaining and utilize the bolt to make up into ring 3 with ring 3 down with last ring 3, and overlap ring 3 on taper sleeve 2, then penetrate connecting plate 6 on the connecting rod 5 that corresponds and utilize gland nut 9 to fix connecting plate 6 on connecting rod 5, penetrate taper sleeve 2 with the cable through body 1 in, then stimulate stay cord 4 right, make stay cord 4 penetrate in the threading pipe, the removal of stay cord 4 drives the removal of connecting plate 6, and then move right through connecting rod 5 drive ring 3. Because ring 3 is located conical sleeve 2 and 2 annular areas of conical sleeve increase gradually right, consequently, ring 3 is when removing, because conical sleeve 2 is extrudeed gradually when ring 3 removes, because set up jaggedly on conical sleeve 2, consequently conical sleeve 2 extrudees main cable under the extrusion of ring 3 to can fix the cable in conical sleeve 2. Thereby effectively clamping the cable. Simultaneously along with the pulling force increase that stay cord 4 received, ring 3 moves towards conical sleeve 2 right side, can press from both sides tight cable more. After wearing out the cable from the threading pipe, at first pull down connecting plate 6 from connecting rod 5, then with first semicircle ring 31 and lower semicircle ring 32 split, and then make ring 3 no longer press from both sides tight tapered sleeve 2, prevent that tapered sleeve 2 from extrudeing the cable, and then make things convenient for the cable to take off from tapered sleeve 2.
A gasket is arranged between the compression nut 9 and the connecting plate 6. The gasket can prevent effectively that gland nut 9 extrusion from destroying connecting plate 6.
The inner wall of the conical sleeve 2 is provided with anti-skid grains. The cable can be effectively prevented from sliding in the conical sleeve 2.
The use of this application can not only be in the same place stay cord 4 and cable junction fast to save the time and physical power of tensile and cable junction consumption, stay cord 4 is when drawing ring 3 simultaneously, and is drawing more, and ring 3 is big more to conical sleeve 2's effort, thereby is big more to the extrusion force of cable, and then prevents that cable and stay cord 4 from breaking away from, and then guarantees the permanent use of device.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
