Description

Technical Field

[0001] The invention relates to the technical field of track antenna routing, in particular to a track antenna routing frame. Background Art

[0002] Urban rail transit system refers to a transportation system that uses vehicles to run on fixed rails in the city and is mainly used for urban passenger transportation. Nowadays, in order to ensure smooth and stable communication with high-speed rail, staff need to perform signal detection on signal towers and other signal transmitting devices near the track along the track to prevent mutual interference of signals. Common signal detection devices are usually installed at the bottom of the train. The outside of the signal detection device is usually connected to multiple cables and respectively passed into each car. Since the cables connected to the outside of the signal detection device are close to the track, in order to prevent the cables from contacting the track ground, it is usually necessary to use a cable rack to support the cables;

[0003] However, the wiring method adopted by the wiring rack in the prior art is usually to insert the cables into the holes reserved on both sides of the wiring rack in turn. This wiring method has certain disadvantages. On the one hand, it is difficult to limit the cables after they are inserted into the holes reserved in the wiring rack, causing multiple strands of cables to become loose in the wiring rack and then cause them to be entangled with each other. On the other hand, the cables need to be further pulled forward after being inserted into the holes reserved in the wiring rack, causing relative sliding between the cables and the wiring rack, which can easily cause the surface of the cables to be scratched by the wiring rack. In addition, during the subsequent maintenance and replacement of the cables inserted into the wiring rack, it is impossible to take out a single cable located in the internal area of ​​the wiring rack for maintenance, which increases the difficulty of maintenance and replacement.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0097] Furthermore, if Fig. 9 As shown, the upper wire fixing mechanism 212 includes:

[0098] The second lifting shaft 2121 is provided with a plurality of groups corresponding to the second wire storage slots 17, and is slidably inserted into the lifting frame 222 up and down. The lifting frame 222 is provided with a second guide hole 2223 for guiding the lifting of the second lifting shaft 2121;

[0099] The upper wire pressing rod 2122 is fixedly connected to the lower end of the second lifting shaft 2121. Both ends of the upper wire pressing rod 2122 are slidably connected to the inside of the second wire storage slot 17 to compress the cable 102 in the first wire storage slot 16.

[0100] Wherein, the upper wire fixing mechanism 212 further includes:

[0101] The second connecting rod 2123 is fixedly sleeved on the outer side of the second lifting shaft 2121 and located between the lifting frame 222 and the upper wire pressing rod 2122. A second threaded hole 21231 runs through the middle of the second connecting rod 2123;

[0104] The second rotating rod 2125 is fixedly connected to the lower end of the second threaded rod 2124 and is used for rotationally adjusting the second threaded rod 2124 .

[0105] As an improvement, Figure 1-3 As shown, a fixing block 18 is fixedly connected to the outer side of the upper portion of the fixing frame 11;

[0106] The lower end of the train 101 near both sides is fixedly connected with mounting rods 19;

[0107] The fixing block 18 is fastened to the lower end of the mounting rod 19 by means of bolts.

[0108] It should be noted that: in the specific implementation process of the present invention, Figure 3-4 As shown, initially, the lower wire pressing rod 2113 is located at the upper part of the first wire storage groove 16, the upper wire pressing rod 2122 is located at the upper part of the second wire storage groove 17, and the revolving doors 12 on both sides of the fixed frame 11 are in an open state. When routing, multiple cables 102 are moved from the bottom of the fixed frame 11 through the corresponding routing grooves 13 and the first wire inlet grooves 14 into the first wire storage groove 16. If the number of cables 102 exceeds the number of the first wire storage grooves 16, for the extra cables 102, the extra cables 102 are moved through the routing grooves 13, the first wire inlet grooves 14, and the second wire storage grooves 17. The second wire entry slot 15 is moved into the second wire storage slot 17, and the cable 102 is transitioned to the fixed frame 11 by using the wire routing slot 13, and the cable 102 is supported by the first wire storage slot 16 and the second wire storage slot 17, without inserting the cable 102 into the fixed frame 11, so that the cable 102 is first pulled, and then the straightened cable 102 is moved into the first wire storage slot 16 and the second wire storage slot 17, ensuring that there is no relative sliding with the wiring rack during the wiring process, and preventing the surface of the cable 102 from being scratched by the wiring rack;

[0109] like Figure 5-6As shown, then, the third rotating rod 2232 is rotated, and the third rotating rod 2232 drives the third threaded rod 223 to rotate. The third threaded rod 223 drives the lifting frame 222 to move downward along the guide groove 111 through the thread cooperation with the third threaded hole 2221. The lifting frame 222 drives the first connecting rod 2114 to move downward through the first threaded rod 2115. The first connecting rod 2114 moves downward along the first guide hole 2222 through the first lifting shaft 2111. The first lifting shaft 2111 drives the lower wire pressing rod 2113 to move downward along the first wire storage groove 16 through the transfer rod 2112, so that the cable 102 in the first wire storage groove 16 is At the same time, when the lifting frame 222 moves downward along the guide groove 111, it also synchronously drives the second threaded rod 2124 to move downward, and the second threaded rod 2124 drives the second lifting shaft 2121 to move downward along the second guide hole 2223 through the second connecting rod 2123, and the second lifting shaft 2121 drives the upper wire pressing rod 2122 to move downward along the second wire storage groove 17, so that the cable 102 in the second wire storage groove 17 is also synchronously pressed, thereby realizing the ability to synchronously limit the cables 102 placed in the first wire storage groove 16 and the second wire storage groove 17 after routing, and avoiding the phenomenon of loose winding of the cables 102 in the wiring frame;

[0110] After the cable 102 is routed, the revolving door 12 is closed to ensure that the cable 102 can be protected by the fixing frame 11 and the revolving door 12 during the travel of the train 101;

[0111] like Figure 5-8 As shown, the present invention arranges the first wire storage slot 16 and the second wire storage slot 17 in parallel up and down, and distributes the first wire storage slot 16 at equal intervals along the fixed frame 11, and the second wire storage slot 17 is also distributed at equal intervals along the fixed frame 11. In this way, while ensuring that each cable 102 keeps a distance between adjacent cables 102 during the routing process, more cables 102 can be accommodated, further reducing the probability of the cables 102 being entangled, and facilitating subsequent inspection and troubleshooting of the cables 102.

[0112] like Figure 5-6 , Fig. 9As shown, in addition, when the cable 102 in the fixed frame 11 fails and needs to be repaired and replaced, the revolving door 12 is opened, and the faulty cable 102 is first found. If the faulty cable 102 is located in the first cable storage slot 16, the first rotating rod 2116 corresponding to the faulty cable 102 is rotated, and the first rotating rod 2116 drives the first threaded rod 2115 to rotate. The first threaded rod 2115 drives the first connecting rod 2114 to move upward under the action of the thread tangential force between the outer thread and the first threaded hole 21141, and the first connecting rod 2114 moves upward through the first lifting The shaft 2111 moves upward along the first guide hole 2222, and the first lifting shaft 2111 drives the lower pressing rod 2113 to move upward along the first wire storage slot 16 to the upper part of the first wire storage slot 16 through the transfer rod 2112, so that the lower pressing rod 2113 corresponding to the faulty cable 102 is lifted, while the remaining lower pressing rods 2113 and upper pressing rods 2122 still press the normal cable 102, and then the faulty cable 102 is transferred out through the first wire inlet slot 14 and the wire routing slot 13 in turn, and then the faulty cable 102 is replaced;

[0113] If the faulty cable 102 is located in the second wire storage slot 17, the second rotating rod 2125 corresponding to the faulty cable 102 is rotated, and the second rotating rod 2125 drives the second threaded rod 2124 to rotate. The second threaded rod 2124 drives the second connecting rod 2123 to move upward under the action of the thread tangential force between the outer thread and the second threaded hole 21231. The second connecting rod 2123 moves upward along the second guide hole 2223 through the second lifting shaft 2121, and the second lifting shaft 2121 drives the upper wire pressing rod 2122 to move along the second wire storage slot 17. Move upward to the upper part of the second wire storage groove 17, so that the upper wire pressing rod 2122 corresponding to the faulty cable 102 is lifted, while the remaining upper wire pressing rods 2122 and lower wire pressing rods 2113 still press the normal cable 102.
