Description

Technical Field

[0001] The invention relates to the field of locomotive external antennas, and in particular to a locomotive external antenna threading structure. Background Art

[0002] In the process of continuous development of the rail industry, the functions of locomotives are constantly enriched and improved. The top of the locomotive is usually equipped with a variety of equipment such as headlights, bagpipes, antennas, etc., among which the number of network communication antennas on the top is also showing an increasing trend. However, when realizing the functions of these antennas, a series of technical difficulties are faced. A large number of antennas need to be passed from the inside of the locomotive to the top of the locomotive. This process has many defects under the existing technology.

[0003] First, the antenna cable is hard and often has an inflexible crimp joint, which makes it very difficult to pass the cable through the elbow and the operability is very poor. When there are multiple cables that need to pass through, the diameter of the steel pipe has to be greatly increased to accommodate these cables. This not only increases the difficulty of manufacturing, but also leads to excessive space occupation, which has an adverse effect on the layout of the locomotive interior. In addition, there is an obvious gap between the pipe clamp and the cable, which cannot effectively ensure water tightness. This is very easy to cause moisture intrusion in a humid or rainy environment, affecting the normal operation and service life of the cable.

[0004] In addition, after the locomotive has been running for a long time, the pipe clamp may become loose or even fall off, which undoubtedly poses a serious safety hazard to driving.

[0005] Finally, the inside of the pipe clamp is prone to rust because it cannot be painted. The rusted pipe clamp not only reduces its own structural strength, but also may damage the cable, thereby threatening the safety of the cable and affecting the normal operation of the entire locomotive.

[0006] In summary, the existing locomotive antenna cable threading technology has many problems, which seriously affects the performance and safety of the locomotive, and new technical solutions are urgently needed to solve these problems. Summary of the invention

[0007] According to the above technical problems, such as the hard texture of antenna cable, gap between pipe clamp and cable, inability to ensure water tightness, looseness and falling of pipe clamp, a wiring structure for external antenna of locomotive is provided. The present invention prevents rainwater from entering the structure by designing the unique structure of outlet box and installation box, and the elastic function of sealing pad and rubber block enables complete sealing between outlet box and installation box, and between cable and installation box.

[0008] The technical means adopted by the present invention are as follows:

[0009] A locomotive external antenna threading structure, comprising: a sealing structure, a connecting structure, a vibration reduction structure, an integrated structure, a mounting box, and an outlet box;

[0010] The sealing structure includes a rubber block and a sealing pad, which utilizes the elastic properties of the material itself to ensure the sealing of the structure, prevent rainwater, dust, debris, etc. from entering the interior of the locomotive, reduce the impact of locomotive vibration on the threading structure, and prevent fasteners from loosening;

[0011] The connecting structure fasteners include screws, nuts, flat washers, and spring washers;

[0012] The diameter of the installation box is greater than the diameter of the outlet box.

[0013] Furthermore, the outlet box, the installation box and the rubber block are connected and fixed by fasteners, and there is ample operating space to meet the requirements of installation, disassembly, inspection and maintenance.

[0014] Furthermore, the integrated structure can meet the use requirements of different cables and has strong adaptability and versatility.

[0015] Furthermore, the integrated structure can adjust and replace the interface size of the rubber block according to the size of the cable structure. Only the size of the square hole inside the rubber block needs to be adaptively adjusted, and other structures remain unchanged.

[0016] Furthermore, the adjustment method of the interface size of the rubber block is simple and easy, and good sealing performance can still be maintained after adjustment.

[0017] Furthermore, the fasteners in the connection structure are made of high-strength, corrosion-resistant materials.

[0018] Furthermore, the vibration reduction structure can effectively absorb the vibration energy generated during the operation of the locomotive and protect the stability of the wire threading structure.

[0019] Furthermore, the structure in which the diameter of the outlet box is smaller than the diameter of the installation box is specially designed to ensure that rainwater cannot enter under all weather conditions.

[0020] Furthermore, the sealing structure, the connection structure, the vibration reduction structure and the integrated structure are matched with high precision, ensuring that the overall performance of the threading structure is stable and reliable.
