A track antenna wiring rack

Abstract

The present invention discloses a track antenna cable rack, comprising: a cable routing unit, mounted on the lower part of a train, for supporting and guiding cables; a cable fixing unit, comprising a main cable fixing assembly mounted on the upper part of the cable routing unit for synchronously compressing all cables in the cable routing unit, and a sub-cable fixing assembly mounted on the lower part of the main cable fixing assembly for compressing individual cables in the cable routing unit. A plurality of cables are sequentially inserted into the cable routing unit from the lower end thereof, and then the main cable fixing assembly is adjusted to drive the sub-cable fixing assembly to synchronously move downward along the interior of the cable routing unit to compress the cables. During the routing process, the cables enter the cable routing unit in an erection manner instead of a penetration manner, thereby preventing the size of the cables from hindering the routing process. After the cables are erected, the sub-cable fixing assembly compresses the cables in the cable routing unit, thereby preventing the cables and the cable routing unit from sliding relative to each other, thereby preventing the cable surfaces from being scratched by the cable rack.

Description

Technical Field

[0001] The present 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 in which vehicles run on fixed rails in a city and is mainly used for urban passenger transportation. Nowadays, in order to ensure smooth and stable communication with high-speed rail, workers need to perform signal detection on signal towers and other signal transmitting devices near the track to prevent mutual signal interference. 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. Because 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, a cable tray is usually required 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 become 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 content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Summary of the Invention

[0005] The object of the present invention is to provide a track antenna wiring rack to solve the problem that the track antenna wiring rack in the prior art proposed in the above background technology supports and routes the cables by inserting the cables into the reserved holes of the wiring rack in sequence. It is difficult to limit the cables after they are inserted into the wiring rack. The cables need to be further pulled forward after they are inserted into the holes reserved for the wiring rack, which can easily cause the surface of the cables to be scratched by the wiring rack.

DETAILED DESCRIPTION

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0062] See also Figure 1-10 , the present invention provides a technical solution:

[0063] A track antenna wiring rack, comprising:

[0064] The cable routing unit 1 is installed at the bottom of the train 101 and is used to support and guide the cables 102;

[0066] It should be noted that: when routing, multiple cables 102 are inserted into the routing unit 1 from the lower end of the routing unit 1 in sequence, and then the main fixed wire assembly 22 is adjusted to drive the sub-fixed wire assembly 21 to move downward synchronously along the inside of the routing unit 1 to compress the cables 102. During the routing process, the cables 102 enter the routing unit 1 in a way of erecting instead of inserting, so as to avoid the size of the cables 102 hindering the routing process. After the cables 102 are erected, the sub-fixed wire assembly 21 is used to press the cables 102 into the routing unit 1, so as to avoid relative sliding between the cables 102 and the routing unit 1, which may cause the surface of the cables 102 to be scratched by the routing rack.

[0067] In addition, when repairing and replacing the cable 102, for the damaged cable 102, the fixed line component 21 on the damaged cable 102 can be picked up separately, and the cable 102 can be moved out of the wiring rack, while the remaining cables 102 that can be used normally remain in the wiring rack, making it convenient to repair and replace the cable 102.

[0096] The first limiting plate 2117 is fixedly connected to the upper end of the first threaded rod 2115 and is located inside the lifting frame 222, and is used to limit the first threaded rod 2115. The first limiting plate 2117 and the first threaded rod 2115 are both rotatably connected to the lifting frame 222. A first limiting groove 2224 for accommodating the first limiting plate 2117 is provided inside the lifting frame 222 and on the outside of the first limiting plate 2117. The first limiting plate 2117 is cylindrical.

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

[0098] The second lifting shafts 2121 are provided in multiple groups corresponding to the second wire storage slots 17 and are slidably inserted into the lifting frame 222. The lifting frame 222 is provided with second guide holes 2223 for guiding the lifting of the second lifting shafts 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 mounted on the outside of the second lifting shaft 2121 and is located between the lifting frame 222 and the upper wire pressing rod 2122. A second threaded hole 21231 is formed in the middle of the second connecting rod 2123.

[0102] The second threaded rod 2124 is threadedly connected to the inside of the second threaded hole 21231;

[0103] A second limiting plate 2126 is fixedly connected to the upper end of the second threaded rod 2124 and is located inside the lifting frame 222. The second limiting plate 2126 and the second threaded rod 2124 are both rotatably connected to the lifting frame 222. A second limiting groove 2225 is provided inside the lifting frame 222 and outside the second limiting plate 2126 for accommodating the second limiting plate 2126.

[0104] The second rotating rod 2125 is fixedly connected to the lower end of the second threaded rod 2124 and is used to rotate and adjust 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 is fixedly connected to mounting rods 19 near both sides;

[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 slot 16, the upper wire pressing rod 2122 is located at the upper part of the second wire storage slot 17, and the revolving doors 12 on both sides of the fixed frame 11 are in the open state. When routing, multiple cables 102 are moved from the bottom of the fixed frame 11 through the corresponding routing slots 13 and the first wire inlet slots 14 into the first wire storage slot 16. If the number of cables 102 exceeds the number of the first wire storage slots 16, the extra cables 102 are respectively moved through the routing slots 13, the first wire inlet slots 14 and the second wire inlet slots 17. The second wire entry slot 15 is moved into the second wire storage slot 17. 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. There is no need to insert 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 the cable 102 does not slide relative to the wiring rack during the wiring process, thereby 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 slot 16 through the adapter rod 2112, so that the cable 102 in the first wire storage slot 16 is pressed. The second threaded rod 2124 is driven downwardly by the lifting frame 222 when it moves downwardly along the guide groove 111. The second threaded rod 2124 drives the second lifting shaft 2121 to move downwardly along the second guide hole 2223 through the second connecting rod 2123. The second lifting shaft 2121 drives the upper wire pressing rod 2122 to move downwardly along the second wire storage groove 17, so that the cables 102 in the second wire storage groove 17 are also synchronously pressed, thereby achieving 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, thereby preventing the cables 102 in the routing frame from being loosely entangled.

[0110] After the cable 102 is routed, the revolving door 12 is closed to ensure that the cable 102 is protected by the fixing frame 11 and the revolving door 12 during the movement 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 fixing frame 11, and the second wire storage slot 17 is also distributed at equal intervals along the fixing frame 11. In this way, while ensuring that each cable 102 maintains a distance between adjacent cables 102 during the routing process, it can also accommodate more cables 102, 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 , Figure 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. 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 groove 16 to the upper part of the first wire storage groove 16 through the adapter 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 the upper pressing rod 2122 still press the normal cable 102. Subsequently, the faulty cable 102 is transferred out through the first wire inlet groove 14 and the wire routing groove 13 in sequence, and then the faulty cable 102 is replaced;

[0113] If the faulty cable 102 is located in the second cable 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 cable storage slot 17. Move upward to the upper part of the second wire storage slot 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. Subsequently, the faulty cable 102 is transferred out through the second wire entry slot 15 and the wiring slot 13 in turn, and then the faulty cable 102 is replaced, so that the remaining normal cables 102 are always kept in a compressed and limited state during the entire cable 102 replacement process, which facilitates the inspection and replacement of the faulty cable 102.
