[0002] With the vigorous development of transportation construction, a number of large-span and super-large-span bridges have been built one after another. People are paying more and more attention to the safety, durability and normal use functions of these large and important bridges.

[0003] At present, in order to facilitate the monitoring of the health status of bridges, most bridge management companies usually use fiber optic sensors to monitor the status of bridges so that bridge management companies can take corresponding solutions in time according to the monitoring results.

[0004] When installing fiber optic sensors, the first thing to do is to lay out the optical cables on the bridge. Currently, most bridge management companies usually need a large number of workers to lift and lay the optical cables to the corresponding positions when laying optical cables. This laying method consumes a lot of manpower and material resources, and the laying efficiency is relatively low. Therefore, further improvements can be made. Summary of the invention

[0008] By adopting the above technical solution, when laying the optical cable, the worker first fixes the head of the optical cable to the first slide, and then pulls the optical cable so that the optical cable can be dragged along the length direction of the cable trough. At the same time, during the process of dragging the optical cable, a slide is added at a certain interval so that multiple slides can support the optical cable at the same time. After the optical cable is dragged to the corresponding position, the worker pushes the optical cable into the cable trough, and installs the optical cable support on multiple node support mechanisms. Since the optical cable is laid by the slide, manpower and material resources can be effectively reduced, and the laying efficiency of the optical cable can be improved.

[0050] Reference Figure 3 Specifically, in this embodiment, the node support mechanism 3 includes a mounting seat 31, a wire receiving column 32 and a switch assembly 33; wherein the mounting seat 31 includes a bottom plate 311 and two side plates 312, the two side plates 312 are arranged opposite to each other, and the two side plates 312 are fixedly mounted on both sides of the bottom plate 311.

[0051] Specifically, there are two groups of switch assemblies 33, each group of switch assemblies 33 includes a switch slide column 331, a preload spring 332 and a handle 333; wherein, the wire receiving column 32 is provided with guide slots 322 on both sides of each wire receiving opening 321, and the guide slots 322 and the wire receiving column 32 are integrally formed, the two guide slots 322 are arranged opposite to each other, each guide slot 322 is in an arc shape, and the center of the guide slot 322 is arranged colinearly with the axis of the wire receiving column 32. The switch slide column 331 is in an arc shape, the center of the switch slide column 331 is the same as the center of the guide slot 322, and the cross-sectional profile of the switch slide column 331 is consistent with the cross-sectional profile of the guide slot 322, so that the switch slide column 331 can be slidably arranged in the guide slot 322. The preload spring 332 is installed in the guide slot 322, and one end of the preload spring 332 is fixed to the bottom of the guide slot 322, and the other end is pressed against the switch slide column 331, so that the two preload springs 332 can be used to push the two switch slide columns 331 to slide towards each other, so that the wire receiving opening 321 can be closed. The handle 333 is installed on the switch slide column 331, and the handle 333 is fixedly installed on the end of the switch guide column away from the guide slot 322, so that the worker can pull the switch slide column 331 to slide along the guide slot 322 through the handle 333.

[0052] In the process of installing the optical cable support on the node support mechanism 3, the worker first pulls the switch slide column 331 through the handle 333 to slide along the guide slide groove 322 so that the wire receiving opening 321 can be opened, and then the worker places the optical cable in the wire receiving opening 321, and finally releases the handle 333, so that the two pre-tightening springs 332 respectively push the two switch slide columns 331 to slide toward each other and press together, so that the wire receiving opening 321 can be closed, thereby completing the work of the optical cable support on the node support mechanism 3.

[0053] In this embodiment, the guide groove 322 corresponding to each wire receiving opening 321 is staggered with the guide groove 322 corresponding to the adjacent wire receiving opening 321, so that the distance between two adjacent wire receiving openings 321 can be further reduced, thereby increasing the number of wire receiving openings 321.

[0054] In this embodiment, a plurality of numbers 323 are provided at one end of the wire receiving column 32, and the plurality of numbers 323 are arranged in sequence along the circumference of the wire receiving column 32, and the plurality of numbers 323 are arranged correspondingly to the plurality of wire receiving openings 321, so that workers can find the optical cable in the corresponding wire receiving opening 321 through the numbers 323, which is convenient for the workers to perform maintenance and inspection work in the later stage.

[0055] The node support mechanism 3 also includes an adjustment component 35, which includes a worm wheel 351, a worm 352 and a rotating wheel 353; wherein, the rotating shaft at one end of the wire support column 32 passes through the side plate 312 to which it is rotatably connected, and the worm wheel 351 is fixedly installed on the rotating shaft, so that the worm wheel 351 can drive the wire support column 32 to rotate through the rotating shaft. The worm 352 is installed on the side plate 312 corresponding to the worm wheel 351, and the worm 352 is vertically rotated and installed on the side plate 312, and the worm 352 is meshed with the worm wheel 351. A transmission rod is provided at the top of the wire trough 1 at the position of each node support mechanism 3, and the transmission rod is vertically rotated and installed on the wire trough 1.

The rotating wheel 353 is installed on the top of the transmission shaft 354, so that the rotating wheel 353 can control the rotation of the worm 352 through the transmission shaft 354.

[0056] When the wire receiving opening 321 aligned with the slot of the cable trough 1 supports an optical cable, by rotating the rotating wheel 353, the rotating wheel 353 drives the worm 352 to rotate, and the worm 352 drives the wire receiving column 32 to rotate through the worm wheel 351, so that the new wire receiving opening 321 can be adjusted to a position relative to the slot of the cable trough 1, which is convenient for workers to install the new optical cable.

[0057] Reference Figure 1 and Figure 2In order to improve the sealing performance of the wire trough 1, in this embodiment, horizontal slide grooves 12 are provided on two opposite inner sides of the wire trough 1. The two horizontal slide grooves 12 are parallel to each other and opposite to each other.

[0058] Since a cover is installed at the slot position of the cable trough 1, it is not easy for external debris such as stones to enter the cable trough 1, so that the cable trough 1 is not easily blocked by debris, which is convenient for the later extraction and maintenance of the optical cable.

[0059] Reference Figure 1 In this embodiment, the sub-cover 4 is also provided with an inspection port, each of which is provided corresponding to a node support mechanism 3, so that workers can inspect and repair the optical cable at the location of the node support mechanism 3 through inspection. An inspection door 41 is also installed in each inspection port, and one end of the inspection door 41 is hinged to the sub-cover 4, so that workers can open / close the inspection port through the inspection door 41.

[0060] The implementation principle of Example 1 is:

[0061] When laying the optical cable, the worker first fixes the head of the optical cable to the first dragging mechanism 2. In the process of fixing the head of the optical cable, the optical cable is first placed between the two clamping plates 25, and then the breaking rod 26 is rotated, and the breaking rod 26 drives the adjusting screw 23 to rotate, so that the two adjusting nuts 24 can drive the two clamping plates 25 to move towards each other, so that the two clamping plates 25 can clamp the optical cable to complete the fixing of the optical cable.

[0062] After the cable head is fixed, the cable is pulled so that the cable can be dragged along the length direction of the cable trough 1. At the same time, during the dragging of the cable, a dragging mechanism 2 is added at a certain interval so that multiple dragging mechanisms 2 can support the cable at the same time.

[0063] After the optical cable is dragged to the corresponding position, the optical cable is pushed into the cable trough 1, and the optical cable support is installed on multiple node support mechanisms 3.

[0064] At the same time, when the receiving opening 321 aligned with the slot of the cable trough 1 supports an optical cable, the rotating wheel 353 drives the worm 352 to rotate, and the worm 352 drives the receiving column 32 to rotate through the worm wheel 351, so that the new receiving opening 321 can be adjusted to a position relative to the slot of the cable trough 1, which is convenient for workers to install new optical cables. Until all optical cables are installed in the receiving opening 321 in the receiving column 32, the installation of optical cables is completed.

[0075] S1. Fix the optical cable head to the dragging mechanism 2: first place the optical cable between the two clamping plates 25, then rotate the lever 26, which drives the adjusting screw 23 to rotate, so that the two adjusting nuts 24 can drive the two clamping plates 25 to move towards each other, so that the two clamping plates 25 can clamp the optical cable to complete the fixing of the optical cable.

[0076] S2. Drag the optical cable along the length direction of the cable trough 1: After the head of the optical cable is fixed, grab the head of the optical cable and drag the optical cable; at the same time, during the dragging process, add a dragging mechanism 2 at a certain interval.

[0077] S3. Supporting the optical cable on the node support mechanism 3: After the optical cable is dragged to the corresponding position, the worker pushes the optical cable into the cable duct 1 and supports and installs the optical cable on multiple node support mechanisms 3.

[0078] Through S1, workers can pull the optical cable through the slide 21, so that the optical cable can be dragged along the length direction of the cable trough 1 for preliminary laying; through S1, during the process of dragging the optical cable, by adding a slide 21 at a certain distance, the optical cable can be supported by multiple slides 21, which facilitates the laying of the optical cable; through S3, workers support and install the optical cable on multiple node support mechanisms 3, and can complete the laying and installation of the optical cable.
