Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of installation tools, and particularly relates to an installation tool for railway tunnel cables. Background Technique
[0002] When a train travels rapidly on the rail, vibration waves will be generated. The vibration waves propagate along the earth's surface and excite the buildings near the railway to vibrate. Although the amplitude and energy of the environmental vibration caused by the railway are relatively small, from the perspective of building safety, it will not cause severe damage like an earthquake.
[0003] Due to the long-term existence and repeated occurrence of the vibration, the repeated action of this persistent small-amplitude environmental vibration will reduce the strength of the building structure, cause cracks in the building walls or structural deformation, thus causing the bolts to loosen, resulting in the shaking or even falling off of the cable brackets fixed to the walls by bolts, and ultimately affecting the safety and normal use of the cables.
[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model
[0005] Regarding the problems in the related technology, the utility model proposes an installation tool for railway tunnel cables to overcome the above technical problems existing in the existing related technology.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model is an installation tool for railway tunnel cables, including a hexagon bolt. A gasket is sleeved on the circumferential surface of the hexagon bolt. A sleeve is sleeved on the circumferential surface of the hexagon bolt and on one side of the gasket. An internal milling cone cap is sleeved on one side inside the sleeve. A resisting block is arranged on the other side of the internal milling cone cap. The resisting block is in sliding fit with the hexagon bolt. A spring is arranged on the other side of the resisting block. Both the resisting block and the spring are sleeved on the hexagon bolt. The internal milling cone cap is threadedly installed with the hexagon bolt.
[0008] Further, the hexagon bolt includes a hexagon rotating block. One end of the hexagon rotating block is fixedly installed with a threaded rod. A cavity is formed inside between the hexagon rotating block and the threaded rod.
[0009] Further, thread lines are formed on the circumferential surface of the threaded rod and inside the cavity. One end of the threaded rod close to the spring is provided with an inclined opening. The thread lines extend from one end of the threaded rod to the other end of the hexagon rotating block.
[0010] Further, the casing includes a pipe body sleeved on the threaded rod. An expansion groove is formed at one end of the pipe body close to the internal milling cone cap, and the diameter of the end of the internal milling cone cap close to the pipe body is smaller than that of the pipe body.
[0011] Further, a plurality of expansion blocks are fixedly installed on the pipe body, and the plurality of expansion blocks are located at the expansion groove.
[0012] Further, the resisting block includes a resisting ring located on one side of the internal milling cone cap and sleeved on the threaded rod. A sliding block is fixedly installed on the inner wall of the resisting ring, and a sliding groove slidably matched with the sliding block is formed on the threaded rod.
[0013] The utility model has the following beneficial effects:
[0014] 1. When the train vibrates during running, the resisting block on one side of the internal milling cone cap will always remain in a state of being in contact with the casing under the elastic action of the spring, ensuring that there is no relative sliding between the casing and the wall, avoiding the situation that the cable bracket shakes or even falls off, and ensuring the safety and normal use of the cable.
[0015] 2. By a worker turning the hexagon bolt with a wrench, the internal milling cone cap is made to push the casing to expand in all directions. Then, the expansion of the casing will firmly press against the wall surface in the hole of the railway tunnel wall. Subsequently, through the mutual extrusion and cooperation among the casing, the internal milling cone cap, the hexagon bolt and the gasket, the bracket between the gasket and the casing is fixed to the wall of the railway tunnel.
[0016] 3. When turning the hexagon rotating block with a wrench, the hexagon rotating block will drive the fixedly installed threaded rod to rotate. Since threaded lines are formed on the circumferential surface of the threaded rod and located in the cavity, when the threaded rod drives the threaded lines to rotate, the stone debris will move towards the direction of the hexagon rotating block through the rotation of the threaded lines, and then the stone debris in the hole is cleaned out of the hole so that the threaded rod can smoothly enter the hole.
[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model.
[0029] Please refer to Figures 1-6As shown, the utility model is an installation tool for railway tunnel cables, including 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 inner side of the sleeve 3, a resisting block 5 is provided 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 provided 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.
[0030] First, prepare the drilling on the wall of the railway tunnel according to the fixed position of the railway tunnel cable, then pass the cable bracket 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, the sleeve 3, the inner milling cone cap 4, the resistance block 5, and the spring 6 into the hole on the wall of the railway tunnel in the adjacent order, and make the spring 6 resist at the innermost of the hole, and then use the staff to turn the hexagonal bolt 1 with a wrench. Due to the threaded installation between the inner milling cone cap 4 and the hexagonal bolt 1, the rotation of the hexagonal bolt 1 The inner milling cone cap 4 installed with the thread will be driven to rotate, and then the inner milling cone cap 4 will move toward the direction of the casing 3. Then, the casing 3 is pushed by the inner milling cone cap 4, so that the end of the casing 3 close to the inner milling cone cap 4 will expand to the surroundings, and the inner milling cone cap 4 will enter the casing 3. The expansion of the casing 3 will make it firmly against the wall surface of the hole in the wall of the railway tunnel. Then, the casing 3, the inner milling cone cap 4, the hexagonal bolt 1 and the gasket 2 will be squeezed and matched with each other, so that the bracket between the gasket 2 and the casing 3 is firmly fixed to the wall of the railway tunnel.
[0031] In addition, the inner milled cone cap 4 located on one side of the sleeve 3 will firmly press against the sleeve 3. When the train vibrates and the bolt becomes loose, the sleeve 3 will be squeezed and deformed between the wall. Then, the resistance block 5 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, ensuring 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.
[0032] Therefore, when the train vibrates, the resistance block 5 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, ensuring that there will be no relative sliding between the sleeve 3 and the wall, avoiding the cable bracket from shaking or even falling off, and ensuring the safety and normal use of the cable.
[0033] Thus, the staff rotates the hexagonal bolt 1 with a wrench, causing the internal milling cone cap 4 to push the sleeve 3 to expand in all directions. Subsequently, the expansion of the sleeve 3 causes it to firmly abut against the wall surface of the hole in the railway tunnel wall. Then, through the mutual extrusion and cooperation among the sleeve 3, the internal milling cone cap 4, the hexagonal bolt 1, and the gasket 2, the bracket between the gasket 2 and the sleeve 3 is fixed firmly to the wall of the railway tunnel.
[0034] In one embodiment, for the above, the hexagonal bolt 1 includes a hexagonal rotating block 101. One end of the hexagonal rotating block 101 is fixedly installed with a threaded rod 102, and a cavity 103 is formed inside between the threaded rod 102 and the hexagonal rotating block 101.
[0035] Thread lines 104 are provided on the circumferential surface of the threaded rod 102 and within the cavity 103. One end of the threaded rod 102 close to the spring 6 is provided with an inclined opening, and the thread lines 104 extend from one end of the threaded rod 102 to the other end of the hexagonal rotating block 101.
[0036] During installation, since there will be residual stone debris in the holes drilled in the wall of the railway tunnel before installation, it will be difficult for the threaded rod 102 to enter the hole. When the threaded rod 102 is moved towards the hole, the stone debris will first enter the cavity 103 opened on the threaded rod 102 through the inclined opening at one end of the threaded rod 102. Subsequently, 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. Since the thread lines 104 are provided on the circumferential surface of the threaded rod 102 and within the cavity 103, when the threaded rod 102 drives the thread lines 104 to rotate, the stone debris will move towards the direction of the hexagonal rotating block 101 through the rotation of the thread lines 104. Then, the stone debris in the hole is cleared outside the hole so that the threaded rod 102 can smoothly enter the hole.
[0037] In one embodiment, for the above sleeve 3, the sleeve 3 includes a tube body 301. The tube body 301 is sleeved on the threaded rod 102. An expansion groove 302 is opened at one end of the tube body 301 close to the internal milling cone cap 4, and the diameter of one end of the internal milling cone cap 4 close to the tube body 301 is smaller than the diameter of the tube body 301.
[0038] A number of expansion blocks 303 are fixedly installed on the tube body 301, and a number of the expansion blocks 303 are located at the expansion groove 302.
[0039] When the threaded rod 102 rotates, the threaded rod 102 drives the internally milled cone cap 4 installed by threads to rotate. Subsequently, the internally milled cone cap 4 moves in the direction of the pipe body 301. Since the caliber of the end of the internally milled cone cap 4 close to the pipe body 301 is smaller than the caliber of the pipe body 301, under the push of the internally milled cone cap 4, the pipe body 301 enables the internally milled cone cap 4 to push several expansion blocks 303 thereon to approach each other, and makes the middle positions between several adjacent expansion blocks 303 expand towards the surroundings and move towards the expansion groove 302. Subsequently, the expanded middle positions between several expansion blocks 303 will firmly abut against the wall surface in the hole of the railway tunnel wall. Subsequently, through the mutual extrusion and cooperation of the sleeve 3, the internally milled cone cap 4, the threaded rod 102 and the gasket 2, the bracket between the gasket 2 and the sleeve 3 is fixed to the wall of the railway tunnel.
[0040] In one embodiment, for the above-mentioned resisting block 5, the resisting block 5 includes a resisting ring 501. The resisting ring 501 is located on one side of the internally milled cone cap 4 and sleeved on the threaded rod 102. A sliding block 502 is fixedly installed on the inner wall of the resisting ring 501, and a sliding groove 105 slidably matched with the sliding block 502 is formed on the threaded rod 102.
[0041] To prevent the bolt from loosening when the train vibrates during driving, the resisting ring 501 on one side of the internally milled cone cap 4 will always be in a state of being in contact with the sleeve 3 under the elastic action of the spring 6. In addition, the sliding groove 105 formed on the threaded rod 102 can ensure that when the threaded rod 102 rotates, the sliding block 502 also rotates along with it. Subsequently, the sliding block 502 drives the resisting ring 501 to rotate, so as to ensure that when the threaded rod 102 rotates, the resisting ring 501 can still be in contact with the sleeve 3, so that there is no relative sliding between the sleeve 3 and the wall, thereby increasing the stability of the cable bracket installed on the hexagon bolt 1.
