DETAILED DESCRIPTION

[0023] This specific embodiment is a rail transportation electromechanical equipment maintenance device, and its structural diagram is as follows Figure 1-Figure 5 As shown, it includes a mounting tube 1, two mounting tubes 1 are provided, the outer walls of the two mounting tubes 1 are respectively provided with evenly distributed rectangular openings 2, the inner walls of the rectangular openings 2 are movably connected with an arc plate 3, one end of the arc plate 3 extends into the mounting tube 1, the outer wall of the mounting tube 1 is provided with evenly distributed square holes 4, a positioning rod 5 is provided in the square hole 4, one end of the positioning rod 5 extends to the outside of the mounting tube 1, and the other end extends into the mounting tube 1, a positioning mechanism is provided on the outer wall of the mounting tube 1, the outer walls of the two mounting tubes 1 are respectively fixedly connected with fixing plates 13, and a tightening mechanism is provided between the two fixing plates 13.

[0024] like Figure 1 and Figure 2 As shown, the positioning mechanism includes an external thread groove 10, which is opened on the outer wall of the mounting tube 1, an internal thread ring 11 is assembled on the side wall of the external thread groove 10, and a tapered ring 12 is sleeved on the side wall of the mounting tube 1, and the tapered ring 12 is fixedly connected to the internal thread ring 11.

[0025] The outer wall of the internal thread ring 11 is hexagonal, and the internal thread of the internal thread ring 11 matches the external thread groove 10, so that the internal thread ring 11 can be moved leftward or rightward by rotating it.

[0026] like Figure 1 and Figure 3 As shown, the tensioning mechanism includes a screw rod 14, which is arranged between the two fixed plates 13. One end of the screw rod 14 is movably connected to the fixed plate 13 through a bearing, and one end of the screw rod 14 passes through the inner ring of the bearing and extends to the outside of the fixed plate 13 and is fixedly connected to a knob 16. A screw hole 15 is opened on one side of one of the fixed plates 13, and one end of the screw rod 14 passes through the screw hole 15 and extends to the outside of the fixed plate 13.

[0027] The distance between the two mounting tubes 1 can be adjusted by the tensioning mechanism, and the cooperation between the screw rod 14 and the screw hole 15 has a self-locking property, and the length of the screw rod 14 can be set according to actual needs.

[0028] Among them, a first movable groove 6 is opened at the top of the positioning rod 5, and an outer pulley 7 is installed on the inner wall of the first movable groove 6, and the outer pulley 7 contacts the inner wall of the conical ring 12. A second movable groove 8 is opened at the bottom end of the positioning rod 5, and an inner pulley 9 is installed on the inner wall of the second movable groove 8, and the inner pulley 9 contacts the arc plate 3.

[0029] In addition, several arc plates 3 are fixedly connected to the side opposite to the center of the mounting tube 1 with evenly distributed anti-slip teeth 17. The anti-slip teeth 17 can increase the friction between the cable sheath and the arc plate 3, effectively improving the fixed clamping effect.

[0030] Among them, the rectangular opening 2 and the arc plate 3 are respectively arranged in a circular array, and the square hole 4 and the positioning rod 5 are arranged in a circular array. The rectangular opening 2 and the arc plate 3 in the circular array can make the force of the arc plate 3 to clamp the cable more uniform when fixing the cable, which can improve the stability of use.

[0031] Working principle: When using this technical solution, if you encounter a broken cable, you need to use a cutting tool to cut the broken ends neatly, and insert the broken ends of the cable into the installation tube 1 respectively. Then, use a wrench to rotate the internal threaded ring 11, and the internal threaded ring 11 drives the conical ring 12 to rotate and move outward, so that the conical ring 12 gradually presses the outer pulley 7 on the positioning rod 5, so that the positioning rod 5 gradually descends, and the positioning rod 5 will contact and press the arc plate 3, so that the anti-slip teeth 17 on the arc plate 3 are in contact with the outer skin of the cable, so that the cable can be compressed and After the cable is fixed in the mounting tube 1, a new section of cable is used to dock the broken cable. During the docking process, if the two ends of the broken cable need to be tightened and pulled closer, the screw rod 14 can be turned forward by turning the knob 16 to make the two fixing plates 13 and the mounting tube 1 gradually approach each other. This can improve the convenience of wiring. When the wiring is completed, the mounting tube 1 is retained on the cable. This can effectively protect the cable wiring point and prevent the weak point of the cable wiring point from breaking again due to pulling, effectively protecting the cable wiring point, which can improve the stability of use.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
