[0009] The frame is provided with a slide groove, and a plurality of sliding blocks are arranged inside the slide groove. One end of the sliding block is connected to the corresponding mounting plate and is used to guide the mounting plate to slide.

[0010] In some embodiments, a plurality of threaded holes are provided on one side of the frame close to the mounting plate, the plurality of threaded holes are symmetrically distributed on the frame, a second threaded hole with a rectangular distribution is provided on the mounting plate, and the frame and the mounting plate are connected by bolts.

[0011] In some embodiments, the slide groove and the slider are both T-shaped, and the slide groove is provided with a slideway near the mounting plate, and the slideway is used to connect the slider and the mounting plate.

[0012] In some embodiments, the height of the slider is the same as the height of the mounting plate.

[0013] In some embodiments, a plurality of fastening strips are abutted against the transverse support beam, and the fastening strips are connected to the transverse support beam by bolts.

[0014] In some embodiments, a plurality of cavities matching the cable troughs are formed at the bottom of the fastening strip, and the cavities are used to accommodate the cables.

[0015] In some embodiments, diameters of the plurality of cable troughs decrease sequentially along the length of the transverse support beam.

[0016] The embodiment of the present application provides a cable bracket for railways, which realizes stable support and flexible arrangement of cables through cable grooves, chambers, racks, mounting plates, transverse support beams, reinforcing beams, cable troughs, slide grooves and sliders.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] An embodiment of the present application provides a cable rack for railways, which can solve the problem in the related art that the distance between the transverse support beams cannot be adjusted, resulting in inflexible arrangement of the cable rack, and the transverse support beams are prone to tilt after long-term use, causing the cables laid on the transverse support beams to slip or shift.

[0024] See also Figure 1-Figure 3 A cable support for railways comprises: a cable groove 1, wherein the cable groove 1 has a chamber 2 for laying cables, a frame 3 is arranged on the chamber 2, a plurality of mounting plates 4 are slidably arranged on the frame 3, a transverse support beam 5 is arranged on one side of the mounting plate 4, a reinforcing beam 6 is arranged between the transverse support beam 5 and the mounting plate 4, the reinforcing beam 6 is used to support the transverse support beam 5, a plurality of cable grooves 7 are provided on the transverse support beam 5, and the cable grooves 7 are used to accommodate cables; a slide groove 8 is provided on the frame 3, a plurality of sliders 9 are arranged inside the slide groove 8, one end of the slider 9 is connected to the corresponding mounting plate 4 and is used to guide the mounting plate 4 to slide, wherein the frame 3 is connected to the chamber 2 by bolts.

[0025] In this embodiment, a chamber 2 is provided inside the cable trench 1, and the chamber is specially designed for laying cables. The chamber 2 provides a protected space for the cables, preventing the cables from being damaged by external environment such as dust, moisture, etc., and ensuring the stable operation of the cables.

[0026] A rack 3 is provided above the chamber 2, and the rack 3 is fixed to the inner wall of the chamber 2 by bolts. A slide groove 8 is provided on the rack 3, and a plurality of sliders 9 are installed inside the slide groove 8. The sliders 9 are connected to the mounting plate 4, so that the mounting plate 4 can slide flexibly on the rack 3, and the position of the mounting plate 4 can be flexibly adjusted according to the wiring requirements of the cables, thereby meeting different cable laying requirements.

[0027] A transverse support beam 5 is provided on one side of the mounting plate 4 for supporting the cable. At the same time, a reinforcing beam 6 is provided between the transverse support beam 5 and the mounting plate 4 to form a stable triangular structure. This structure not only enhances the load-bearing capacity of the bracket, but also effectively prevents the transverse support beam from tilting or deforming after long-term use.

[0028] A plurality of cable troughs 7 are provided on the transverse support beam 5. The cable troughs 7 are used to accommodate cables. The design of the cable troughs 7 allows the cables to be laid neatly and orderly while preventing the cables from sliding or wearing during operation.

[0029] In summary, the railway cable bracket realizes stable support and flexible arrangement of cables, can adjust the distance between the transverse support beams 5 according to the wiring situation, is simple and convenient to operate, has high work efficiency, and improves the stability of the transverse support beams 5, avoiding the cables thereon from slipping or displacing during use, thereby ensuring the layout efficiency and protection performance of the cables.

[0030] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the frame 3 is provided with a plurality of threaded holes 12 on one side close to the mounting plate 4, and the plurality of threaded holes 12 are symmetrically distributed on the frame 3. The mounting plate 4 is provided with a rectangularly distributed threaded hole 2, and the frame 3 and the mounting plate 4 are connected by bolts.

[0031] A number of threaded holes 12 are provided on one side of the rack 3 near the mounting plate 4. These threaded holes 12 are symmetrically distributed on the rack, ensuring the uniform distribution and stability of the connection points. At the same time, the mounting plate 4 also has two threaded holes distributed in a rectangular pattern, which match the threaded holes 12 on the rack 3. With this design, the rack 3 and the mounting plate 4 can be connected by bolts, which pass through the threaded holes 2 on the mounting plate 4 and are tightly combined with the threaded holes 12 on the rack 3 to form a firm connection structure. This connection method not only strengthens the connection strength between the rack and the mounting plate, but also improves the stability and load-bearing capacity of the entire cable rack.

[0032] Further, such as Figure 2 and Figure 3As shown, in this embodiment, the slide groove 8 and the slider 9 are both T-shaped, and the slide groove 8 is provided with a slideway 10 near the mounting plate 4, and the slideway 10 is used to connect the slider 9 with the mounting plate 4.

[0033] Both the slide groove 8 and the slider 9 are T-shaped. This design helps to increase the contact area between the slide groove 8 and the slider 9, thereby improving the stability and reliability of sliding. The T-shaped structure enables the slider 9 to be more tightly embedded in the slide groove 8, reducing shaking and deviation during sliding.

[0034] A slideway 10 is specially provided on one side of the chute 8 close to the mounting plate 4. The main function of the slideway 10 is to serve as a connecting passage between the slider 9 and the mounting plate 4. Through the slideway 10, the slider 9 can be smoothly connected to the mounting plate 4 to form a stable whole.

[0035] It should be noted that the slider 9 and the mounting plate 4 are integrally cast.

[0036] The slider 9 and the mounting plate 4 are designed as an integrated casting. The slider 9 and the mounting plate 4 are cast as a whole during the manufacturing process, and there is no independent connection or interface between them. This integrated design not only improves the strength and stability of the structure, but also simplifies the installation and disassembly process. Since the slider 9 and the mounting plate are integrated, the connection between them is more secure and is not easy to loosen or fall off.

[0037] Preferably, in this embodiment, the height of the slider 9 is the same as the height of the mounting plate 4 .

[0038] In actual operation, the height of the slider 9 is designed to be the same as the height of the mounting plate 4, ensuring the vertical consistency of the slider 9 and the mounting plate 4, so that they can slide in the slide groove 8 as a whole, which helps to maintain stability and balance during the sliding process and prevent shaking or deviation caused by height differences.

[0039] Furthermore, the slider and the mounting plate 4 have the same height, and the connection between them is tighter, which reduces possible gaps or looseness, helps to enhance the stability of the entire structure, and ensures that the mounting plate 4 and the transverse support beam 5 can withstand the impact and vibration of the external environment.

[0040] In addition, the height matching of the slide block 9 and the mounting plate 4 also simplifies the installation and maintenance process. During installation, there is no need to additionally adjust the position of the slide block 9 or the mounting plate 4, and they only need to be placed together in the chute.

[0041] As a preferred embodiment, in this embodiment, a plurality of fastening strips 11 are abutted against the transverse support beam 5 , and the fastening strips 11 are connected to the transverse support beam 5 by bolts.

[0042] A plurality of fastening strips 11 are abutted on the transverse support beam 5. The main function of the fastening strips 11 is to further enhance the fixing effect of the cable on the transverse support beam 5 and prevent the cable from sliding or shifting during operation. The fastening strips 11 can realize multiple fixations of the cable and improve the overall stability of the cable support.

[0043] The fastening strip 11 is connected to the transverse support beam 5 by bolts, which has the advantages of simple structure and firm connection. By selecting appropriate bolt specifications and tightening force, the tight fit between the fastening strip 11 and the transverse support beam 5 can be ensured to prevent the cable fixing failure caused by looseness.

[0044] Furthermore, in this embodiment, a plurality of cavities matching with the cable trough 7 are provided at the bottom of the fastening strip 11, and the cavities are used to accommodate cables, wherein the cavities are semi-arc-shaped.

[0045] The bottom of the fastening strip 11 is provided with a plurality of cavities adapted to the cable trough 7. The shape and size of the cavities are precisely designed according to the cable trough 7 to ensure that they can fit together tightly, so that the cables can be placed more firmly in the cable trough, reducing the shaking and displacement of the cables on the bracket.

[0046] The cavity is designed in a semi-arc shape, which matches the shape of the cable and can better accommodate and fix the cable.

[0047] In this embodiment, the diameters of the plurality of cable troughs 7 decrease successively along the length direction of the transverse support beam 5 .

[0048] The diameters of the plurality of cable troughs 7 provided on the transverse support beam 5 are not uniform, but decrease in sequence along the length direction of the transverse support beam, and the accommodating space of the cable troughs decreases gradually from one end to the other end.

[0049] The main purpose of this diameter change is to accommodate cables of different sizes. During the cable laying process, a suitable cable trough can be selected for installation according to the diameter of the cable to be laid. Larger cables can be placed in a cable trough with a larger diameter, while smaller cables can be placed in a cable trough with a smaller diameter. This design not only makes full use of the space of the transverse support beam 5, but also ensures that cables of different sizes can be firmly supported.
