Description

Technical Field

[0001] The present invention belongs to the technical field of cable brackets, and particularly relates to a multi-purpose combined cable bracket for railway tunnels and subways. Background Art

[0002] Railway tunnels are mainly used for railway traffic crossing, with complex construction environments and many safety issues. Subways, on the other hand, are mainly used for rapid public transportation within or between cities, with advantages such as high efficiency, speed, and environmental friendliness. In railway tunnels and subway systems, in order to effectively support and fix intricate cable lines, cable brackets, an important facility, are usually widely used. These brackets not only ensure the stable layout of cables but also play a crucial role in ensuring the safe and stable operation of the entire transportation system.

[0003] During the use of existing cable brackets, the cable brackets are mainly used to support cables, but they lack the ability to be adjusted and combined according to different cable types and specifications, which makes it difficult for cable brackets to meet diverse cable laying requirements. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a multi-purpose combined cable bracket for railway tunnels and subways to solve the problems brought about by the inability of existing cable brackets to be adjusted and combined according to different cable types and specifications.

The upper outer surfaces of the limit screws are all threadedly connected with fastening nuts. Two mounting rods are movably inserted through one end of the mounting seat, and the mounting seat is movably inserted into the limit groove.

[0011] Preferably, a fixing frame is movably inserted and connected between the limiting groove and the outer surface of the support rod. Positioning rods are arranged on both sides of one end of the fixing frame. A support frame is arranged at the top end of the support rod, and a mounting frame is installed at one end of the support frame away from the limiting groove.

[0012] Preferably, the bracket structure includes an adjusting structure. Connecting plates are fixedly connected to both sides of the bottom end of the adjusting structure. Two through slots are respectively formed at one end of each connecting plate. Movable blocks are movably inserted and connected in the through slots. Two springs are fixedly connected between the movable blocks and the lower slot walls in the through slots. Support wheels are movably installed between adjacent movable blocks. The connecting plates are installed at one end of two first connecting blocks.

[0013] Preferably, the adjusting structure includes fixing plates, connecting grooves, lead screws, fixing blocks and fixing wheels. There are two fixing plates, connecting grooves, lead screws and fixing blocks respectively. Two connecting grooves are respectively formed at one end of the two fixing plates. The two lead screws are respectively movably inserted and connected in the two connecting grooves. The two fixing blocks are respectively threadedly connected to the outer surfaces of the two lead screws. The fixing wheel is fixedly connected between the two lead screws. The fixing plates are fixedly connected to the top ends of the connecting plates.

[0014] Preferably, the fixing seat is fixedly connected to the top end of the mounting plate.

[0015] Preferably, the mounting seat is movably inserted and connected to the outer surface of the support rod.

[0016] Preferably, the limiting structure includes a support block, an L-shaped frame, a displacement rod and a pressing block. The L-shaped frame is fixedly connected to one side of the top end of the support block. The displacement rod is threadedly connected to the middle of the top end of the L-shaped frame. The bottom end of the displacement rod penetrates through the bottom end of the L-shaped frame and extends below it.

[0017] Preferably, the movable plate is fixedly connected to the middle of the bottom end of the support block. An insertion rod is fixedly inserted into the movable plate. Support plates are movably inserted and connected to the outer surfaces of both sides of the insertion rod. The second connecting block is threadedly connected to the outer surface of one side of the insertion rod.

[0018] Preferably, the pressing block is located directly above the support block. The middle parts of the bottom end of the pressing block and the top end of the support block are both provided with arc-shaped structures.

[0019] Preferably, the fixing wheel is located above the middle of the two support wheels.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) By setting the support wheel, fixed wheel, screw rod, fixed block, limit screw rod, mounting plate, mounting seat and mounting rod, the mounting seat can slide in the limit groove, thereby driving the support seat to move synchronously, and then fix it with the mounting rod. During the installation process, the mounting plate is properly installed first, and then the cable is placed on the top surface of the two support wheels. By moving the fixed wheel, the screw rod slides smoothly in the connecting groove. When the fixed wheel is close to the outer surface of the cable, the fixed block is used to lock it, thereby effectively limiting the cable. This design ensures that the device can flexibly adapt to various specifications and types of cables, fully meeting the diverse cable laying needs.

[0022] (2) By setting the support wheel, movable block, groove and spring, when the cable is pulled, the support wheel can rotate freely in the direction of the pulling force. At the same time, the movable block also slides smoothly and unimpeded inside the groove. This sliding action is accompanied by the moderate contraction of the spring. The spring, with its good elasticity, effectively buffers the impact caused by the pulling force, thereby cleverly reducing the friction between the cable and the device, avoiding any potential damage to the cable due to excessive friction, which not only ensures the safety of the cable, but also greatly improves the smoothness and efficiency of the entire laying process.

[0023] (3) By setting up displacement rods, L-shaped frames, clamping blocks, movable plates, insertion rods, second connection blocks and support blocks, the angle of the support block is adjusted according to the actual laying path of the cable to ensure that it perfectly matches the direction of the cable. Subsequently, the support block is firmly fixed in the appropriate position using the insertion rod. Next, the cable is placed inside the support block and fixed by the clamping block, thereby achieving a firm fixation of the cable and ensuring the stability and safety of the cable during the laying process.

Detailed implementation manners

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figure 1 - Figure 6 As shown in the figure, the multi-purpose railway tunnel and subway combined cable bracket includes:

[0034] Support rod 1;

[0035] One end of the support rod 1 is provided with a limit groove 2, and a plurality of mounting structures 7 are equidistantly installed in the limit groove 2. The tops of the mounting structures 7 are equidistantly installed with a plurality of support structures 8, and one ends of the support structures 8 are all provided with a limiting structure 9;

[0036] The support structure 8 includes a fixing seat 81, a movable frame 82 is installed in the fixing seat 81, both ends of the movable frame 82 are fixedly connected with a first connecting block 83, and one ends of the first connecting blocks 83 at both ends are jointly installed with a bracket structure 84;

[0037] The mounting structure 7 includes a mounting seat 71, one end of the mounting seat 71 is fixedly connected with a support seat 73, both sides of one end of the support seat 73 are fixedly connected with a limit screw 74, and an installation plate 75 is movably inserted through the outer surfaces of the two limit screws 74 in common. The upper outer surfaces of the limit screws 74 are all threadedly connected with fastening nuts 76. Two mounting rods 72 are movably inserted through one end of the mounting seat 71, and the mounting seat 71 is movably inserted into the limit groove 2.

[0038] ByFigure 1 and Figure 3 - Figure 5 It can be seen that a fixing frame 3 is movably inserted and connected between the inside of the limiting groove 2 and the outer surface of the support rod 1. Positioning rods 4 are arranged on both sides of one end of the fixing frame 3. A support frame 5 is arranged at the top end of the support rod 1. An installation frame 6 is installed at one end of the support frame 5 away from the limiting groove 2;

[0039] The bracket structure 84 includes an adjusting structure 841. Connecting plates 842 are fixedly connected to both sides of the bottom end of the adjusting structure 841. Two through slots 843 are respectively opened at one end of each of the connecting plates 842. Movable blocks 845 are movably inserted and connected in the through slots 843. Two springs 844 are fixedly connected between the movable blocks 845 and the lower slot walls in the through slots 843. Support wheels 846 are movably installed between adjacent pairs of movable blocks 845. The connecting plates 842 are installed at one ends of two first connecting blocks 83;

[0040] The adjusting structure 841 includes fixing plates 11, connecting grooves 12, lead screws 13, fixing blocks 14 and fixing wheels 15. There are two fixing plates 11, connecting grooves 12, lead screws 13 and fixing blocks 14. Two connecting grooves 12 are respectively opened at one ends of the two fixing plates 11. Two lead screws 13 are respectively movably inserted and connected in the two connecting grooves 12. Two fixing blocks 14 are respectively threadedly connected to the outer surfaces of the two lead screws 13. The fixing wheel 15 is fixedly connected between the two lead screws 13. The fixing plate 11 is fixedly connected to the top end of the connecting plate 842.

[0041] As described above, slide the mounting seat 71 in the limiting groove 2 so that the support seat 73 is displaced synchronously. After the mounting seat 71 reaches the ideal position, fix it. During the installation process, the mounting plate 75 is inserted around the two limiting screws 74 and fixed by the fastening nuts 76, realizing the installation and disassembly of the mounting plate 75. The cable is placed on the top surface between the two support wheels 846. The support wheels 846 provide stable support for the cable. At this time, move the fixing wheel 15 so that the lead screw 13 firmly connected to the fixing wheel 15 slides smoothly in the connecting groove 12. When the fixing wheel 15 is in close contact with the outer surface of the cable, the cable is effectively limited by locking the fixing block 14. This design ensures that the device can flexibly adapt to different types and specifications of cables and meet the diversified cable laying requirements.

[0042] Embodiment Two:

[0043] Refer to Figure 4As shown in the figure, the support structure 84 includes an adjustment structure 841. Both sides of the bottom end of the adjustment structure 841 are fixedly connected with connecting plates 842. Two through slots 843 are respectively opened at one end of each connecting plate 842. Movable blocks 845 are movably inserted into the through slots 843. Two springs 844 are fixedly connected between the movable blocks 845 and the lower slot walls in the through slots 843. Support wheels 846 are movably installed between adjacent movable blocks 845. The connecting plates 842 are installed at one ends of two first connecting blocks 83.

[0044] As can be seen from the above, during the process of pulling the cable, the support wheels 846 will rotate naturally in response to the pulling force. At the same time, the movable blocks 845 slide smoothly in the through slots 843. Along with this process, the springs 844 contract moderately, effectively avoiding potential damage to the cable caused by excessive friction.

[0045] Preferably, the fixed seat 81 is fixedly connected to the top end of the mounting plate 75;

[0046] The mounting seat 71 is movably inserted into the outer surface of the support rod 1;

[0047] The fixed wheel 15 is located above the middle of the two support wheels 846.

[0048] As can be seen from the above, movably inserting the mounting seat 71 into the outer surface of the support rod 1 improves the stability of the mounting seat 71. The fixed wheel 15 is arranged above the middle of the two support wheels 846, thus facilitating the limiting of the cable.

[0049] Embodiment Three:

[0050] Reference Figure 6 As shown in the figure, the limiting structure 9 includes a support block 91, an L-shaped frame 92, a displacement rod 93 and a pressing block 94. The L-shaped frame 92 is fixedly connected to one side of the top end of the support block 91. The displacement rod 93 is threadedly connected to the middle of the top end of the L-shaped frame 92. The bottom end of the displacement rod 93 penetrates through the bottom end of the L-shaped frame 92 and extends below it. The pressing block 94 is connected to the bottom end of the displacement rod 93 by a bearing;

[0051] The movable plate 95 is fixedly connected to the middle of the bottom end of the support block 91. An insertion rod 96 is fixedly inserted into the movable plate 95. Support plates 97 are movably inserted into the outer surfaces on both sides of the insertion rod 96. The second connecting block 98 is threadedly connected to the outer surface of one side of the insertion rod 96. The two support plates 97 are respectively fixedly connected to the bottom ends of the two first connecting blocks 83.

[0052] As can be seen from the above, according to the actual route of the cable, the angle of the support block 91 can be conveniently adjusted and fixed at an appropriate position by the insertion rod 96. Subsequently, the cable is placed in the support block 91, and the displacement rod 93 is gently rotated. The displacement rod 93 rotates smoothly and descends slowly in the L-shaped frame 92, thereby pushing the pressing block 94 connected to it by a bearing downward until the pressing block 94 tightly clamps and fixes the cable in the support block 91.

[0053] Preferably, the pressing block 94 is located directly above the support block 91, and the middle parts of the bottom end of the pressing block 94 and the top end of the support block 91 are both provided with arc-shaped structures.

[0054] As can be seen from the above, the middle parts of the bottom end of the pressing block 94 and the top end of the support block 91 are both provided with arc-shaped structures, so that the cable can be stably fixed according to the arc surface of the cable.

[0055] Furthermore, the design of the present invention is applied to the cable installation in railway tunnels and subways. The support rod 1 is closely attached to the inner walls of railway tunnels and subways. Subsequently, the fixing frame 3 is slid flexibly in the limit groove 2 to a predetermined position and fixed by the positioning rod 4. Then, the mounting seat 71 also slides smoothly in the limit groove 2, and this action drives the support seat 73 closely connected to it to move synchronously. After the mounting seat 71 reaches the ideal position, it is fixed by the mounting rod 72. During the installation process, the mounting plate 75 is inserted around the two limit screws 74, and through the restraint of the limit screws 74 and the tightening of the fastening nuts 76, the quick and convenient installation and disassembly of the mounting plate 75 are realized;

[0056] Entering the cable installation link, the cable is placed on the top surface of the two support wheels 846. The support wheels 846 provide stable support for the cable. At this time, the fixed wheel 15 is moved, so that the lead screw 13 firmly connected to the fixed wheel 15 slides smoothly in the connection groove 12. When the fixed wheel 15 is close to the outer surface of the cable, the cable is effectively limited by the locking of the fixed block 14. This design ensures that the device can flexibly adapt to different types and specifications of cables and meet the diverse cable laying requirements;

[0057] During the process of pulling the cable, the support wheels 846 will rotate naturally in response to the pulling force. At the same time, the movable block 845 slides smoothly in the through groove 843. Along with this process, the spring 844 contracts moderately, effectively avoiding potential damage to the cable caused by excessive friction. In addition, according to the actual route of the cable, the angle of the support block 91 can be conveniently adjusted and fixed at an appropriate position by the insertion rod 96. Subsequently, the cable is placed in the support block 91, and the displacement rod 93 is gently rotated. The displacement rod 93 rotates smoothly and descends slowly in the L-shaped frame 92, thereby pushing the pressing block 94 connected to it by a bearing downward until the pressing block 94 tightly clamps and fixes the cable in the support block 91.

[0058] In summary, the entire installation and adjustment process is both smooth and efficient, fully demonstrating the flexibility and practicality of the device in cable laying.
