Description

A multi-functional cable bracket for urban rail transit signal construction Technical Field

[0001] This invention belongs to the field of urban rail transit signal construction technology, and specifically relates to a multifunctional cable bracket for urban rail transit signal construction. Background Technology

[0002] With the continuous expansion of urban rail transit construction, the signaling system, as a core facility ensuring the safety and efficiency of train operation, faces increasingly higher requirements for construction precision and efficiency. Signal cables, as the carrier of signal transmission, undergo multiple stages during construction, including laying, fixing, debugging, and maintenance, and must adapt to complex environments such as tunnels, viaducts, and stations.

[0003] Traditional cable brackets typically only have a single support or limiting function, for example:

[0004] Fixed supports can only provide static support for cables through rigid structures, and cannot adjust the height, angle, or tension of the cables according to the construction stage;

[0005] While sliding supports can enable the lateral transport of cables, they lack the ability to precisely position and fix the cables. During construction, the cables are prone to shifting due to vibration or external forces, and the transport process can easily cause cable jams, affecting transport efficiency.

[0006] This functional disconnect means that construction workers need to frequently change the type of support or auxiliary tools, significantly increasing construction time and labor costs.

[0007] Therefore, there is a need for a multifunctional cable support for urban rail transit signal construction to solve the problems of existing technologies, such as the inability to adjust cable support according to the construction stage and low cable transmission efficiency.

The rear end of the driven pulley is connected to the front end of the rotating shaft.

[0016] In a preferred embodiment, the fixed shaft is disposed on the rotating disk near the lower outer periphery, and the connecting shaft is disposed on the rotating wheel near the outer periphery of the rotating wheel, with the fixed shaft and the connecting shaft located on the same axis.

[0017] In a preferred embodiment, the alternating assembly includes two first hinge seats, which are symmetrically fixedly connected to both sides of the rotating disk.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Please refer to Figures 1-8. This invention provides a multifunctional cable bracket for urban rail transit signal construction, including a base 1, a column 2, and a support plate 3. The column 2 is fixedly connected to the top of the base 1, and the support plate 3 is fixedly installed on the top of the column 2. The support plate 3 is provided with a conveying mechanism 4 for conveying the cable body 7. The support plate 3 is also provided with an anti-jamming mechanism 5 for cooperating with the conveying mechanism 4 to adjust the conveying of the cable body 7. Above the conveying mechanism 4 and the anti-jamming mechanism 5, a limit adjustment mechanism 6 is provided on the upper part of the support plate 3 for cooperating with the conveying mechanism 4 to adjust the conveying process of the cable body 7.

[0034] The anti-jamming mechanism 5 includes a reciprocating rotation component 51 and an alternating component 52. The reciprocating rotation component 51 is connected to the conveying mechanism 4 and is mounted on the column 2 and the support plate 3. The alternating component 52 is mounted on the conveying mechanism 4 via the reciprocating rotation component 51.

[0035] The limit adjustment mechanism 6 includes an adjustment component 61 and a limit component 62. The adjustment component 61 is located on the top of the support plate 3, and the limit component 62 is located above the conveying mechanism 4 via the adjustment component 61.

[0036] Further, as shown in Figures 1, 2, 3, 4, and 5, it is worth noting that the conveying mechanism 4 includes a support base 401, which is fixedly installed on the top of the support plate 3. A rotating shaft 403 is rotatably installed on the support base 401. The front end of the rotating shaft 403 passes through the support base 401 and is connected to the reciprocating rotating component 51. A support roller 402 is fixedly connected to the rotating shaft 403. Support frames 404 are fixedly connected to the support plate 3 on the left and right sides of the support base 401. A support 405 is fixedly connected to the top of the support frame 404. A guide roller 406 is rotatably installed on the support 405. The support frame 404 has a C-shaped cross-section and passes through the support plate 3. The support frame 404 has an opening on the support plate 3 to accommodate the alternating component 52.

[0037] In use, the cable body 7 can be conveyed on the support plate 3 with the support roller 402, and the guide rollers 406 arranged on both sides can further ensure the stability of the cable body 7 in the upper part, thereby improving its conveying efficiency.

[0038] Further, as shown in Figures 2, 3, 4, 5, and 6, it is worth noting that the reciprocating rotating assembly 51 includes a mounting groove 511, which is formed on the column 2 and located below the support plate 3. A rotating disk 512 is disposed within the mounting groove 511, and a fixed shaft 513 is rotatably mounted on the rotating disk 512. The fixed shaft 513 is fixedly installed within the mounting groove 511. An adjusting groove 514 is formed on the rotating disk 512, and a rotating wheel 515 is slidably disposed within the adjusting groove 514. A connecting shaft 516 is fixedly connected to the rotating wheel 515, and the fixed shaft 513 is mounted on the rotating disk 512. The connecting shaft 516 is located near the lower outer periphery of the rotating wheel 515. The fixed shaft 513 and the connecting shaft 516 are located on the same axis. The connecting shaft 516 is rotatably mounted on the column 2 through the mounting groove 511. The front end of the connecting shaft 516 is fixedly connected to the drive pulley 517. The drive pulley 517 is fitted with a belt 518. The drive pulley 517 is connected to the driven pulley 519 above the drive pulley 517 through the belt 518. The belt 518 is located on the support plate 3 and has a through hole 5110. The rear of the driven pulley 519 is connected to the front end of the rotating shaft 403.

[0039] In use, the support roller 402 conveys the cable body 7, causing the support plate 3 to rotate, which in turn drives the driven pulley 519 to rotate. Through the belt 518, the driven pulley 517 rotates. Since the connecting shaft 516 is connected to the driven pulley 517, the connecting shaft 516 drives the rotating wheel 515 to rotate in the adjusting groove 514. The rotating wheel 515 rotates in the adjusting groove 514, causing the rotating disk 512 to swing back and forth in the mounting groove 511 through the fixed shaft 513. In this way, the sequential pushing of the cable body 7 is achieved through the reciprocating operation of the alternating component 52, which is convenient to cooperate with the alternating component 52 to improve the efficiency of the cable body 7 on the conveying mechanism 4.

[0040] Further, as shown in Figures 2, 3, 4, and 5, it is worth noting that the alternating assembly 52 includes two first hinge seats 521, which are symmetrically fixedly connected to both sides of the rotating disk 512. A first connecting rod 522 is hingedly mounted on the first hinge seat 521, and the other end of the first connecting rod 522 is hinged to the support frame 404. A second hinge seat 523 is fixedly connected to the first connecting rod 522, and a second connecting rod 524 is hingedly mounted on the second hinge seat 523. A third hinge seat 525 is hingedly mounted at the top of the second connecting rod 524, and a connecting seat 526 is fixedly connected to the top of the third hinge seat 525. A third connecting rod 527 is fixedly connected to the surface of the connecting seat 526 near the support frame 404, and the end of the third connecting rod 527 is hinged to the support frame 404. An adjusting roller 528 is rotatably mounted on the upper part of the connecting seat 526.

[0041] In use, the reciprocating swing of the rotating disk 512 causes the first hinge seat 521 connected to it to swing alternately. This, in turn, drives the second connecting rod 524 through the first connecting rod 522 to push the third connecting rod 527 to move on the support frame 404. As a result, the adjusting roller 528 pushes the cable body 7 above it alternately, so that the cable body 7 can form a certain conveying pattern when conveyed by the conveying mechanism 4. This effectively prevents the conveying from getting stuck and improves the conveying efficiency, thereby improving the practicality of the device.

[0042] As can be seen from the above working process, by using the conveying mechanism 4 in conjunction with the anti-jamming mechanism 5, the cable body 7 can be stably conveyed on the device during construction and conveying work. At the same time, according to the conveying status of the cable body 7, the anti-jamming mechanism 5 can repeatedly push the cable body 7 during the conveying process, causing it to move and be conveyed intermittently on the device, thereby effectively preventing the cable body 7 from jamming during conveying, thus improving its conveying stability and conveying efficiency.

[0043] As further shown in Figures 2, 3, and 7, it is worth noting that the adjusting component 61 includes a fixed frame 611, which is fixedly connected to the top of the support plate 3. A screw 612 is rotatably connected to the top of the fixed frame 611, and a rotating handle 613 is fixedly connected to the top of the screw 612. A U-shaped frame 614 is threaded onto the screw 612. The U-shaped frame 614 is provided with a matching limiting groove 615 on the fixed frame 611. A stop block 616 is fixedly connected to the bottom of the U-shaped frame 614, and the U-shaped frame 614 slides at the upper limit of the fixed frame 611 through the limiting groove 615.

[0044] Further, as shown in Figures 2, 3, 7, and 8, it is worth noting that the limiting component 62 includes a mounting shaft 621, which is rotatably mounted on a U-shaped frame 614. A V-shaped frame 622 is rotatably mounted on the mounting shaft 621. Limiting ports 623 are provided at both ends of the V-shaped frame 622. A sliding groove 624 is provided inside the limiting port 623. A sliding seat 625 is slidably disposed inside the limiting port 623 through the sliding groove 624. A limiting roller 626 is rotatably connected to the sliding seat 625. A connecting plate 627 is fixedly connected to the side of the sliding seat 625 near the V-shaped frame 622. A matching movable groove 629 is provided on the connecting plate 627 corresponding to the V-shaped frame 622. A spring 628 is fixedly connected to one side of the connecting plate 627 inside the movable groove 629 and is fixedly installed inside the movable groove 629.

[0045] In use, rotating the lever 613 drives the screw 612 to rotate, which in turn causes the U-shaped frame 614 to slide on the fixed frame 611 through the limiting groove 615. This allows adjustment of the height of the V-shaped frame 622 to accommodate the specifications of the cable body 7 being transported. Adjusting the distance between the limiting roller 626 and the guide roller 406 effectively prevents the cable body 7 from shaking on the device, thus improving the stability of the cable body 7 transport. At this time, the elastic force of the spring 628 causes the limiting roller 626 to be elastically limited within the slide groove 624 through the slide block 625 and the connecting plate 627, thereby improving the tightness of the connection between it and the cable body 7, and ensuring the stability of the cable body 7 transport. Furthermore, by adjusting the height of the V-shaped frame 622 through the adjusting component 61, the limiting component 62 can clamp and limit the cable body 7 on the conveying mechanism 4, thus supporting and limiting the cable body 7 for construction positioning operations, thereby improving the practicality of the device.

[0046] This solution has the following working process: When this device is used, during the construction support and positioning of the cable body 7, the limit adjustment mechanism 6, in conjunction with the conveying mechanism 4, facilitates the adjustment of the conveying interval between the limit adjustment mechanism 6 and the conveying mechanism 4 according to the specifications of the cable body 7. This ensures stable conveying of the cable body 7 through the conveying mechanism 4. Under the adjustment of the adjustment component 61, the limit component 62, in conjunction with the conveying mechanism 4, can clamp and limit the cable body 7 on the conveying mechanism 4, thus facilitating the construction operation of the limited cable body 7. When the cable body 7 is conveyed through the limit adjustment mechanism 6 and the conveying mechanism 4, the rotation of the cable body 7 on the support roller 402 drives the anti-jamming mechanism 5. The reciprocating rotation component 51, in conjunction with the alternating component 52, can sequentially push and move the conveyed cable body 7, effectively preventing jamming during the conveying of the cable body 7 on the conveying mechanism 4. This ensures the continuity of the cable body 7 during the construction conveying process and improves its conveying efficiency.

[0047] In summary: By using the conveying mechanism 4 in conjunction with the anti-jamming mechanism 5, the cable body 7 can be stably conveyed on the device during construction and conveying operations. Simultaneously, based on the conveying status of the cable body 7, the anti-jamming mechanism 5 repeatedly pushes the cable body 7 during conveying, causing it to move intermittently on the device, effectively preventing jamming and thus improving conveying stability and efficiency. Furthermore, the limit adjustment mechanism 6, in conjunction with the conveying mechanism 4, allows for matching adjustment of the conveying distance of the conveying mechanism 4 according to the specifications of the cable body 7 being conveyed, thereby improving the stability of the cable body 7's conveying. The limit adjustment mechanism 6 also facilitates stable limiting operations on the cable body 7 on the device, ensuring it is clamped and limited for construction operations, thus improving the device's practicality.
