[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Embodiment 1:

[0024] like Figure 1-3 As shown, a railway gauge rod thread repair tool comprises a repair nut 1, a sleeve 2 is welded on one side of the repair nut 1, a connecting plate 3 is welded on one end of the sleeve 2, a square hole 4 is opened on the connecting plate 3, the sleeve 2 is provided with a through hole 5 penetrating the outer walls on both sides of the sleeve 2, two knife groove square steels 6 are symmetrically welded on the other side of the repair nut 1, a tungsten steel blade 7 and a cushion block 8 are inserted in the knife groove square steel 6, a fixing bolt 9 is threadedly connected to the knife groove square steel 6, the bolt tail of the fixing bolt 9 is pressed on the cushion block 8, and a locking nut 10 is threadedly connected to the fixing bolt 9.

[0025] The square hole 4 on the connecting plate 3 is used to connect an electric wrench, which is driven by the electric wrench to reduce the work intensity. The tungsten steel blade 7 is used to clean and repair the wire path of the railway gauge rod. The material strength of tungsten steel is relatively high, and it is not easy to damage when repairing a deformed or burred wire path. The pad 8 is used to squeeze the tungsten steel blade 7 to fix it, and the pad 8 can evenly transmit the tightening force of the fixing bolt 9 to the tungsten steel blade 7 to prevent the tungsten steel blade 7 from being damaged or broken. The fixing bolt 9 and the locking nut 10 are used to support the pad 8.

[0026] A square knife groove 11 penetrating the knife groove square steel 6 is provided on the knife groove square steel 6, and an inner thread hole 12 is opened on the other side of the knife groove square steel 6. The inner thread hole 12 is connected to the square knife groove 11, and the axis of the inner thread hole 12 is perpendicular to the axis of the square knife groove 11. The axes of the square knife grooves 11 on the two knife groove square steels 6 are located on the same radial line of the repair nut 1.

[0027] The tungsten steel blade 7 is located on one side of the square knife groove 11 close to the repair nut 1 . The tungsten steel blade 7 is inserted into the knife groove square steel 6 through the square knife groove 11 , and the blade head of the tungsten steel blade 7 faces the internal threaded hole of the repair nut 1 .

[0028] The width of the tungsten steel blade 7 is the same as the width of the square blade groove 11, and the blade head of the tungsten steel blade 7 is inclined.

[0029] The pad 8 is located on one side of the square knife groove 11 close to the inner thread hole 12. The pad 8 is inserted into the knife groove square steel 6 through the square knife groove 11. One side of the pad 8 is close to the tungsten steel blade 7, and there is a gap between the other side of the pad 8 and the inner wall of the square knife groove 11.

[0030] The width of the pad 8 is the same as that of the tungsten steel blade 7 , and the length of the pad 8 is the same as that of the square knife groove 11 . A circular groove 13 is provided on one side of the pad 8 close to the inner thread hole 12 . The diameter of the circular groove 13 is larger than the outer diameter of the fixing bolt 9 , and the circular groove 13 is coaxial with the inner thread hole 12 .

[0031] The fixing bolt 9 is threadedly connected to the knife groove square steel 6 through the inner thread hole 12 , and the bolt tail of the fixing bolt 9 is located in the circular groove 13 .

[0032] When adjusting the position of the tungsten steel blade 7, it is only necessary to loosen the locking nut 10 and the fixing bolt 9, and make the bolt tail of the fixing bolt 9 still located in the circular groove 13. Since there is a gap between the cushion block 8 and the knife groove square steel 6, the cushion block 8 can move, but is still limited by the fixing bolt 9 and will not fall out of the square knife groove 11. At this time, the tungsten steel blade 7 does not have the squeezing force of the gasket, so it can also move, and the position of the tungsten steel blade 7 can be adjusted at this time.

[0033] The repair nut 1 is a high-strength hexagonal nut. The high-strength hexagonal nut has high strength and is not easily damaged, thereby ensuring the service life of the utility model.

[0034] Embodiment 2:

[0035] This embodiment provides a railway gauge rod thread repair tool, the structure and construction of which are basically the same as those of the embodiment 1, except that:

[0036] like Figure 4 As shown, a rotating rod 14 is inserted into the through hole 5 on the sleeve 2.

[0037] If there is no electric wrench during cleaning and repair, the rotating rod 14 can be inserted into the through hole 5 and rotated manually, and a longer rotating rod 14 can be used to reduce the work intensity. Although the manual repair method of this embodiment is slower than that of embodiment 1, it can ensure that repair and cleaning can continue when there is no electric wrench or the electric wrench is damaged, and the repair and cleaning effect is not affected.

[0038] The working principle of the utility model is:

[0039] When in use, first screw the repair nut 1 on the railway gauge rod for a few turns, then adjust the position of the tungsten steel blade 7 so that the blade head of the tungsten steel blade 7 is located in the wire path of the railway gauge rod, tighten the fixing bolt 9 so that the bolt tail of the fixing bolt 9 is located in the circular groove 13 and tightly supports the cushion block 8. The cushion block 8 tightly supports the tungsten steel blade 7, and then tighten the locking nut 10 to fix the position of the bolt, thereby completing the fixation of the tungsten steel blade 7.

[0040] After fixing the tungsten steel blade 7, insert the rotating end of the electric wrench into the square hole 4, start the electric wrench, and drive the repair nut 1 to rotate on the railway gauge rod. At the same time, the tungsten steel blade 7 cleans the rust, dirt and other debris in the wire path. One end of the cleaned railway gauge rod is inserted into the sleeve, so it will not hinder the cleaning work. The tungsten steel blade 7 has a high strength and can repair the deformed or burred wire path.

[0041] If there is no electric wrench during cleaning and repair, the rotating rod 14 can be inserted into the through hole 5 and rotated manually, and a longer rotating rod 14 can be used to reduce the work intensity. Although the manual repair method is slower, it can ensure that repair and cleaning can continue when there is no electric wrench or the electric wrench is damaged, and the repair and cleaning effect will not be affected.

[0042] When adjusting the position of the tungsten steel blade 7, it is only necessary to loosen the locking nut 10 and the fixing bolt 9, and make the bolt tail of the fixing bolt 9 still located in the circular groove 13. Since there is a gap between the cushion block 8 and the knife groove square steel 6, the cushion block 8 can move, but is still limited by the fixing bolt 9 and will not fall out of the square knife groove 11. At this time, the tungsten steel blade 7 does not have the squeezing force of the gasket, so it can also move, and the position of the tungsten steel blade 7 can be adjusted at this time.

[0043] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0044] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
