[0032] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0034] See also Figure 1-Figure 8 As shown, the utility model is a railway tunnel cable installation bolt assembly, comprising a hexagonal bolt 1, a gasket 2 is sleeved on the circumferential surface of the hexagonal bolt 1, a sleeve 3 is sleeved on the circumferential surface of the hexagonal bolt 1 and on one side of the gasket 2, an inner milling cone cap 4 is sleeved on one side of the sleeve 3, a resisting block 5 is arranged on the other side of the inner milling cone cap 4, the resisting block 5 and the hexagonal bolt 1 are slidably matched, a spring 6 is arranged on the other side of the resisting block 5, the resisting block 5 and the spring 6 are both sleeved on the hexagonal bolt 1, and the inner milling cone cap 4 and the hexagonal bolt 1 are threadedly installed;

[0035] A bracket 7 is provided between the gasket 2 and the sleeve 3, and the bracket 7 is sleeved on the hexagonal bolt 1. A fixing component 8 is symmetrically fixedly installed on one end of the bracket 7, and an engaging component 9 is meshed at one end of two of the fixing components 8. The engaging component 9 is fixedly installed with the bracket 7, and two clamping rods 10 are clamped on the circumferential surface of the engaging component 9, and the two clamping rods 10 are rotatably installed on the bracket 7.

[0036] First, prepare drilling holes on the wall of the railway tunnel according to the fixed position of the railway tunnel cable, then pass the bracket 7 through the hexagonal bolt 1 and place it between the gasket 2 and the sleeve 3, and then put the hexagonal bolt 1 and the gasket 2, sleeve 3, inner milling cone cap 4, resistance block 5, and spring 6 into the hole on the wall of the railway tunnel in a state of being adjacent in sequence, and make the spring 6 resist at the innermost part of the hole, and then the staff will use a wrench to turn the hexagonal bolt 1. Due to the threaded installation between the inner milling cone cap 4 and the hexagonal bolt 1, the rotation of the hexagonal bolt 1 will drive the threaded inner milling cone cap 4 to rotate, and then the inner milling cone cap 4 moves toward the direction of the sleeve 3, and then the sleeve 3 is pushed by the inner milling cone cap 4; so that the end of the sleeve 3 close to the inner milling cone cap 4 expands to the surroundings, The inner milling cone cap 4 enters the sleeve 3, and the expansion of the sleeve 3 will make it firmly against the wall surface of the hole in the wall of the railway tunnel. Then, the sleeve 3, the inner milling cone cap 4, the hexagonal bolt 1 and the gasket 2 are squeezed and matched with each other, so that the bracket between the gasket 2 and the sleeve 3 is fixed to the wall of the railway tunnel. In addition, the inner milling cone cap 4 on one side of the sleeve 3 will firmly press against the sleeve 3. When the train vibrates during running and the bolt becomes loose, the sleeve 3 will be squeezed and deformed with the wall. Then, the resistance block 5 on one side of the inner milling cone cap 4 will always keep in contact with the sleeve 3 under the elastic action of the spring 6, ensuring that there is no relative sliding between the sleeve 3 and the wall, thereby increasing the stability of the cable bracket installed on the hexagonal bolt 1.

[0037] When installing the cable, first pass the cables of different thicknesses through the two fixing components 8. By manually rotating the two fixing components 8 according to the thickness of the cable, the two fixing components 8 will make the internal components evenly converge or move away from the central axis, that is, the internal components of the fixing components 8 move toward the outer wall of the cable and make the two fixing components 8 fix the cable. Then the two fixing components 8 will drive the meshing meshing components 9 to rotate. When the cable is fixed, rotate the two clamping rods 10 to respectively engage with the meshing components 9, so that the gravity of the cable will not cause the problem of the fixing components 8 not fixing the cable firmly.

[0038] Thus, by manually rotating the two fixing components 8 according to the thickness of the cable, the fixing components 8 will make the internal components evenly converge or move away from the central axis, so that the size of the inner cavity between the two fixing components 8 changes, that is, the size of the cavity between the fixing components 8 is adjusted according to the thickness of the cable to adapt to the thickness of the cable, thereby clamping and fixing cables of different thicknesses.

[0039] Thus, the two clamping rods 10 and the engaging assembly 9 are engaged with each other, so that the engaging assembly 9 limits the rotation of the two fixing assemblies 8, ensuring that the fixing assembly 8 can firmly limit the cable on the middle cavity.

[0040] In one embodiment, for the above-mentioned hexagonal bolt 1, the hexagonal bolt 1 comprises a hexagonal rotating block 101, and a threaded rod 102 is fixedly mounted on one end of the hexagonal rotating block 101.

[0041] The sleeve 3 includes a tube body 301, which is sleeved on the threaded rod 102. An expansion groove 302 is opened on one end of the tube body 301 close to the inner milling cone cap 4. The diameter of the end of the inner milling cone cap 4 close to the tube body 301 is smaller than the diameter of the tube body 301.

[0042] When the hexagonal rotating block 101 is rotated with a wrench, the hexagonal rotating block 101 will drive the fixedly installed threaded rod 102 to rotate. When the threaded rod 102 rotates, the threaded rod 102 will drive the threadedly installed inner milling cone cap 4 to rotate, and then the inner milling cone cap 4 will move toward the direction of the tube body 301. Since the diameter of the end of the inner milling cone cap 4 close to the tube body 301 is smaller than the diameter of the tube body 301, the tube body 301 is pushed by the inner milling cone cap 4, so that the inner milling cone cap 4 can push the several expansion blocks 303 thereon to approach each other, and make the middle positions between the adjacent expansion blocks 303 expand toward the surroundings and move toward the expansion groove 302. Then, the expanded middle positions between the expansion blocks 303 will firmly resist the wall surface in the wall hole of the railway tunnel, and then, through the mutual extrusion and cooperation between the casing 3, the inner milling cone cap 4, the threaded rod 102 and the gasket 2, the bracket between the gasket 2 and the casing 3 is secured to the wall of the railway tunnel.

[0043] In one embodiment, for the above-mentioned tube body 301 , a plurality of expansion blocks 303 are fixedly mounted on the tube body 301 , and the plurality of expansion blocks 303 are located at the expansion groove 302 .

[0044] The resistance block 5 includes a resistance ring 501, which is located on one side of the inner milling cone cap 4 and is sleeved on the threaded rod 102. A sliding block 502 is fixedly installed on the inner wall of the resistance ring 501, and a sliding groove 105 that slides with the sliding block 502 is opened on the threaded rod 102.

[0045] To prevent the bolts from loosening when the train vibrates during running, the resisting ring 501 located on one side of the inner milled cone cap 4 will always maintain a fit with the sleeve 3 under the elastic action of the spring 6. In addition, the sliding groove 105 provided on the threaded rod 102 can ensure that when the threaded rod 102 rotates, the sliding block 502 also rotates therewith, and then the sliding block 502 drives the resisting ring 501 to rotate, thereby ensuring that when the threaded rod 102 rotates, the resisting ring 501 can also maintain a fit with the sleeve 3, so that there will be no relative sliding between the sleeve 3 and the wall, thereby increasing the stability of the cable bracket installed on the hexagonal bolt 1.

[0046] In one embodiment, for the above-mentioned fixing component 8, the fixing component 8 includes a fixing plate 801, and a plurality of sliding rods 802 are slidingly installed on the fixing plate 801. A sliding groove that slides with the plurality of sliding rods 802 is opened on the fixing plate 801, and each of the sliding rods 802 is fixedly installed with a fixing plate 803, and a circle is formed between the plurality of fixing plates 803.

[0047] In one embodiment, for the sliding rod 802 , a rotating disk 804 is slidably mounted on the other end of the sliding rod 802 , a fixing rod 805 is fixedly mounted on one end of the two rotating disks 804 close to each other, and a gear bar 806 is symmetrically fixedly mounted on the fixing rod 805 .

[0048] When installing the cable, first pass the cables of different thicknesses through the two fixed disks 801, and rotate the fixed rod 805 by hand according to the thickness of the cable, then the fixed rod 805 will drive the two fixed rotating disks 804 to rotate, and then the rotating disk 804 will drive the plurality of sliding rods 802 to rotate, and the plurality of sliding rods 802 will move along the direction of the sliding groove under the action of the sliding groove opened on the fixed disk 801, and then the plurality of sliding rods 802 will drive the rotating disk 804 fixedly installed thereon to move, so that the rotating disk 804 moves toward the direction of the outer wall of the cable and reaches the two fixed components 8 to fix the cable, and then the inner cavity size between the plurality of sliding rods 802 is changed, that is, the cavity size between the plurality of sliding rods 802 is adjusted according to the thickness of the cable to adapt to the thickness of the cable, thereby clamping and fixing cables of different thicknesses.

[0049] In one embodiment, for the above-mentioned meshing assembly 9, the meshing assembly 9 includes two rotating gears 901, and the two rotating gears 901 are respectively meshed on the two gear bars 806, and a rotating rod 902 is fixedly installed at one end of the two gear bars 806 close to each other.

[0050] The rotating rod 902 is rotatably mounted on the bracket 7 , and the two clamping rods 10 are respectively clamped with the rotating gear 901 .

[0051] The rotation of the fixed rod 805 will drive the fixedly installed gear bar 806 to rotate, and then the gear bar 806 will drive the meshing rotating gear 901 to rotate, and the two rotating gears 901 will drive the rotating rod 902 between them to rotate under the support of the bracket 7. After the plurality of sliding rods 802 fix the cable line, the two clamping rods 10 are rotated to clamp with the meshing rotating gear 901 respectively, so that at this time, the fixed component 8 will not cause the problem of loose fixation of the cable line due to the gravity of the cable line, and it is ensured that the plurality of sliding rods 802 will firmly limit the cable line on the middle cavity.
