Description

Technical Field

[0001] This utility model relates to the field of transmission cable fixing technology, and in particular to a subway signal transmission cable fixing device. Background Technology

[0002] Signal transmission cables are a type of signal transmission tool. Within subway sections, signal transmission cables need to be secured using fixing devices according to their environment to ensure protection and stability. Cable laying is prone to crossing and tangling. In specific situations, such as when cables are laid along walls in subway sections and encounter wall corners, bending is necessary. If the bending radius is not carefully considered, the cable can easily bend sharply, causing damage and affecting its lifespan.

[0003] Regarding the above situation, the biggest problem in existing technologies during cable laying is that the bending radius of the cable is sometimes not reached, resulting in obvious sharp bends. The bending radius of the cable must not be less than 15D, and in special circumstances, it must not be less than the manufacturer's specification. If it is less than the manufacturer's specification, the cable needs to be rerouted according to the site conditions to avoid affecting the cable's service life. During laying, it is necessary to ensure that the cable does not take "sharp bends" to avoid risks. However, the corresponding construction efficiency and cable laying effect will also be affected.

[0004] Therefore, based on the above-mentioned technical problems, in order to avoid hard bends when laying and fixing subway signal transmission cables, those skilled in the art urgently need to develop a subway signal transmission cable fixing device. Utility Model Content

[0005] The purpose of this invention is to provide a subway signal transmission cable fixing device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a subway signal transmission cable fixing device, comprising:

[0008] A fixing frame, wherein both ends of the fixing frame are bent at the same angle as the corner wall to fit against the two surfaces of the corner wall for fixing;

[0009] The roller is fixedly connected to the corner position of the fixed frame and protrudes outward from the corner position. The roller is used to support the subway signal transmission cable and make the cable roll on the roller. Multiple rollers with the same structure are fixed and distributed vertically at intervals along the corner line of the fixed frame.

[0010] The arc-shaped support body consists of two sets of identical structures, symmetrically arranged on two surfaces of the fixed frame located on both sides of the roller;

[0011] Connecting ears are arranged in pairs that are parallel to each other and spaced apart, and are fixedly connected to the outer surface of the arc-shaped support. Each pair of connecting ears corresponds to one roller. Multiple pairs of connecting ears are arranged along the horizontal direction of the arc-shaped support. Limiting holes are provided at the ends of the connecting ears.

[0012] The curved cover plate consists of two sets of identical curved cover plates, which are arranged one-to-one with the two sets of curved support bodies. When the two sets of curved cover plates cover the curved support bodies, their end faces are joined together. The curved cover plate has an assembly opening that corresponds one-to-one with the position and number of the connecting ears so that the connecting ears can pass through.

[0013] And a limiting pin, which is used to pass through the limiting holes on multiple connecting ears in a vertical direction to fix the arc-shaped cover plate.

[0014] Furthermore, the two ends of the fixing bracket are fixed to the limiting holes on the connecting ears on the two sides of the corner wall by expansion screws.

[0015] Furthermore, the curved support body is fixed to the mounting frame by adhesive bonding.

[0016] Furthermore, the rollers protrude from the outer surface of the two sets of arc-shaped support bodies.

[0017] Furthermore, the two sets of curved cover plates are connected at their joints by adhesive bonding.

[0018] Furthermore, the two ends of the limiting pin are limited by pins to prevent the limiting pin from disengaging from the limiting hole on the connecting ear.

[0019] Furthermore, the inner side of the arc-shaped cover plate has a groove structure for accommodating subway signal transmission cables.

[0020] In the above technical solution, the subway signal transmission cable fixing device provided by this utility model has the following beneficial effects:

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-5 A subway signal transmission cable fixing device, comprising:

[0032] The fixing frame 1 has two ends bent at the same angle as the corner wall to fit against the two sides of the corner wall for fixing, so that the fixing frame 1 can be stably fixed at the corner position on the wall, thereby providing a good support foundation for the subsequent installation of the fixing device;

[0033] Roller 2 is fixedly connected to the corner position of the fixed frame 1 and protrudes outward from the corner position. Roller 2 is used to support the subway signal transmission cable and make the cable roll on roller 2. Multiple rollers 2 are fixed with the same structure and are vertically spaced along the corner line of the fixed frame 1 so that multiple cables can be arranged. With the rolling support of the cable by roller 2, damage to the cable is effectively avoided during the cable laying and pulling process.

[0034] The curved surface support 3 consists of two identical sets symmetrically arranged on two surfaces of the fixed frame 1 located on both sides of the roller 2. This arrangement allows the two sets of curved surface supports 3 to support the cable with a larger bending radius, exceeding the cable bending standard, thus preventing hard bends during cable installation and effectively protecting the cable laying. Furthermore, if... Figure 1 , Figure 2 As shown, the arc formed by the curved support 3, after supporting the cable, allows the cable to smoothly transition to the wall surface through a transition curve, so as to carry out regular wiring for the front and back of this position.

[0035] Connecting ears 4 are arranged in pairs that are parallel to each other and spaced apart, and are fixedly connected to the outer surface of the arc support 3. Each cable is arranged through the gap between the two connecting ears 4 in each group. Each group of connecting ears 4 corresponds to a roller 2, so that the cable between the two connecting ears 4 in each group continues to run on the corresponding roller 2 for wiring. Multiple groups of connecting ears 4 are arranged in the horizontal direction of the arc support 3, so as to more comprehensively and stably isolate and separate the wiring, and avoid the crossing and mess between cables. Limiting holes 5 are opened at the end of the connecting ears 4 to facilitate subsequent installation and fixing.

[0036] The curved cover plate 6 consists of two sets of identical curved cover plates 6, which are arranged one-to-one with the two sets of curved support bodies 3. The curved cover plate 6 presses onto the curved support body 3 to protect the cable. When the two sets of curved cover plates 6 cover the curved support body 3, their end faces are joined together to form a complete closed surface at the corner position to effectively protect the cable. The curved cover plate 6 has an assembly port 7 that corresponds one-to-one with the position and number of connecting ears 4 so that the connecting ears 4 can pass through to achieve overall assembly.

[0037] And a limiting pin 8, which is used to pass through the limiting holes 5 on multiple connecting ears 4 in a vertical direction to fix the arc-shaped cover plate 6. The limiting pin 8 restricts the arc-shaped cover plate 6 from detaching from the connecting ears 4 by limiting it, so as to complete the fixing of the arc-shaped cover plate 6.

[0038] Furthermore, the two ends of the fixing bracket 1 are fixed to the limiting holes 5 on the connecting ears 4 on the two sides of the corner wall by expansion screws. The expansion screws can be installed by countersunk holes. The longitudinal width of the fixing bracket 1 should be the same as or higher than the longitudinal width of the arc cover plate 6 to facilitate the installation of the arc cover plate 6 on the fixing bracket 1.

[0039] Furthermore, the curved support 3 is fixed to the fixing frame 1 by adhesive bonding, or it can also be fixed by conventional methods such as bolt connection.

[0040] Furthermore, the roller 2 protrudes from the outer surface of the two sets of arc-shaped supports 3 to provide good support for the cable at the corner position, effectively preventing wear on the cable during the laying process. The roller 2 and the two sets of arc-shaped supports 3 form a good transition, preventing the cable from bending excessively under the support of the roller 2.

[0041] Furthermore, the two sets of curved cover plates 6 are connected by adhesive bonding or sealed with silicone sealant, etc., for sealing purposes only, so that the two sets of curved cover plates 6 form a whole and effectively protect the cable. The main support connection is provided by the connecting ear 4 structure.

[0042] Furthermore, the two ends of the limiting pin 8 are limited by pins to prevent the limiting pin 8 from disengaging from the limiting hole 5 on the connecting ear 4, so that a stable connection is formed between the limiting pin 8 and the connecting ear 4, so that the limiting pin 8 and the connecting ear 4 cooperate to form a stable limit on the arc cover plate 6, so as to stably protect and fix the cable.

[0043] Furthermore, the inner side of the curved cover plate 6 has a groove structure to accommodate the subway signal transmission cable, so as to better match the cable's structure and prevent structural compression or excessive looseness that would cause the cable to sway, making the device more stable in fixing the subway signal transmission cable.

[0044] In summary, this device arranges curved supports for the cables at the corners of the walls where the cables are laid. The support structure, with a bending angle greater than the specified value, protects the subway signal transmission cables at the corners and protects them with a curved cover plate. At the same time, the cables at the corners are supported by rollers to prevent damage to the cables during the laying and pulling process, effectively ensuring the safety of the subway signal transmission cables when laid and fixed at corners.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
