Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0027] In order to solve the technical problems in the background art, such as Figure 1-5 As shown, this application provides a technical solution: a railway cable protection device, characterized as follows:

[0028] The mounting base 1 is made of high-strength materials, such as steel or aluminum alloy, to ensure its structural stability and durability. The mounting base 1 has an internally threaded hole 2 for mating with the screw 4, thus connecting the mounting base 1 and the screw 4. A fastening clamp 3 is located at the bottom of the mounting base 1; its material can be metal or high-strength plastic to accommodate main cables of different diameters. The fastening clamp 3 is connected to the mounting base 1 by bolts, clips, or other fastening mechanisms, ensuring the main cable can be securely fixed. One end of the screw 4 has an annular ring 5, the interior of which is spherically designed to provide flexible angle adjustment. The screw 4 is mated to the internally threaded hole 2 via a thread at its other end and secured to the mounting base 1 by a nut, ensuring the stability of the entire device. A sleeve 6, made of wear-resistant material, is located within the annular ring 5, and has a hollow universal ball 7 in its center, allowing the sleeve 6 to rotate freely in multiple directions. The omnidirectional ball 7 fits into the inner spherical surface of the annular ring 5, ensuring that the sleeve 6 can rotate flexibly within the annular ring 5 to adapt to forces in different directions. A fastening nut 8 is located on the external threaded end of the sleeve 6 and is used to secure the branch line passing through the sleeve 6 to the sleeve 6. The fastening nut 8, tightened by rotation, ensures a secure connection between the branch line and the sleeve 6, preventing loosening due to vibration or external forces.

[0029] It should be noted that the internal threaded holes 2 are evenly distributed along the length of the fixing seat 1, thus providing multiple mounting points to accommodate the main cable in different positions. The diameter and pitch of the internal threaded holes 2 are determined according to the specifications of the screw 4 to ensure that the screw 4 can be smoothly screwed in and fixed. The internal threaded holes 2 can be formed by machining such as lathe machining or thread milling to ensure the accuracy and consistency of the threads.

[0030] Furthermore, the movable connection between the fastening hoop 3 and the fixed base 1 allows the fastening hoop 3 to rotate or slide freely on the fixed base 1 to accommodate cable mainlines of different diameters or shapes. The movable connection can be designed using various mechanisms, such as rotary joints, sliding grooves, or other flexible mechanical connection methods. The movable connection can be achieved by providing a series of sliding grooves on the fixed base 1, with corresponding protrusions on the fastening hoop 3 allowing it to move within the sliding grooves. Another implementation method is to provide bearings or rollers between the fastening hoop 3 and the fixed base 1 to reduce friction and improve flexibility.

[0031] It should be noted that the auxiliary support 9 is a structural component designed to enhance the stability and adjustability of the railway cable protection device. The auxiliary support 9 is typically made of high-strength materials, such as steel or aluminum alloy, to ensure its load-bearing capacity and durability. One end of the auxiliary support 9 has a through hole 11 for connection to the fixed base 1. The diameter and shape of the through hole 11 are designed to match the connecting screw 4 on the fixed base 1 to ensure a secure connection. The other end of the auxiliary support 9 has an adjustment groove 12 for mounting an additional screw 4 to provide adjustment functionality for the branch line. An additional screw 4 can be installed within the adjustment groove 12, parallel to the screw 4 on the fixed base 1, achieving coaxial adjustment. The two screws 4 are connected by a universal ball 7 within their annular ring 5 and a sleeve 6, allowing the sleeve 6 to adjust its direction, thereby adjusting the direction of the branch line. By adjusting the position of the screw 4 on the auxiliary support 9 within the adjustment groove 12, the position of the branch line can be adjusted. This design allows for fine-tuning of the cable position to suit different installation environments and maintenance needs.

[0032] It should be noted that the adjusting ring 10 is designed with a T-shaped structure. This design allows the adjusting ring 10 to connect to both the auxiliary support 9 and the screw 4 simultaneously, providing adjustment functionality. The adjusting ring 10 should be made of durable and high-strength materials, such as stainless steel or high-strength plastic, to ensure its stability and reliability during adjustment. One end of the adjusting ring 10 is designed as a hollow ring, which passes through the screw 4 so that the adjusting ring 10 can slide along the screw 4. The inner diameter of the hollow ring should be slightly larger than the outer diameter of the screw 4 to ensure smooth passage through the screw 4. The other end of the adjusting ring 10 is provided with an external thread, which is used to connect with the side wall thread of the auxiliary support 9. The pitch and diameter of the external thread should match the side wall thread of the auxiliary support 9 to ensure a secure connection. The threaded end of the adjusting ring 10 is screwed into the side wall thread of the auxiliary support 9 to achieve a fixed connection. This connection method allows the adjusting ring 10 to move axially along the side wall of the auxiliary support 9 to adjust the position of the screw 4. One hollow annular end of the adjusting ring 10 passes through the screw 4 and is then connected to the top wall of the auxiliary support 9, which can be a threaded connection or other fastening method. This connection method allows the adjusting ring 10 to fix the position of the screw 4 while allowing for fine adjustments along the axial direction of the screw 4.

[0033] It should be noted that the hollow annular end of the adjusting ring 10 has two key dimensions: the inner diameter and the outer diameter. The inner diameter is slightly larger than the outer diameter of the screw 4 to ensure that the adjusting ring 10 can slide smoothly along the screw 4 while maintaining a tight fit and preventing loosening. The outer diameter is larger than the width of the adjusting groove 12, which ensures that the adjusting ring 10 is stably positioned within the adjusting groove 12 and will not fall off.

[0034] It is worth noting that the elastic washer is a ring-shaped elastomer, usually made of rubber, silicone, or other elastic materials, used to improve the sealing and stability between the fastening clamp 3 and the fixing seat 1. The elastic washer can also absorb vibration and impact, reducing loosening of the connection caused by vibration during railway operation.

[0035] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
