Description

Technical Field

[0001] This invention relates to the field of catwalk paving, and in particular to a rapid segmented sliding paving device and method for catwalk mesh. Background Technology

[0002] A catwalk is a linear temporary construction path erected under and parallel to the main cable during the construction of a suspension bridge. Typically, cable saddles are first installed on the main towers at both ends of the suspension bridge. Then, the catwalk load-bearing cables and catwalk guardrail cables are connected to the winch via the cable saddles. Next, a surface net is laid over the catwalk load-bearing cables and catwalk guardrail cables, and walking ladders are installed over the surface net to facilitate the movement of construction workers.

[0003] Traditional catwalk construction typically involves manually laying the catwalk's surface netting, then using binding wires to secure the netting, the catwalk's load-bearing cables, and the catwalk's guardrail cables. Finally, the walkway ladders are attached to the netting. This method is limited by the construction environment, resulting in a small number of people working simultaneously, which greatly restricts the efficiency of catwalk construction. Therefore, there is still room for improvement. Summary of the Invention

[0004] To improve the efficiency of catwalk construction, this application provides a rapid segmented sliding laying device and method for catwalk mesh.

[0005] Firstly, the rapid segmented sliding laying device for catwalk mesh provided in this application adopts the following technical solution:

[0006] A rapid segmented sliding installation device for catwalk netting includes a catwalk support cable for supporting the catwalk, a catwalk guardrail cable for supporting the catwalk railing, and several fixing frames disposed on the catwalk support cable for fixing the catwalk netting. The fixing frames are detachably installed on the catwalk support cable and the catwalk guardrail cable. After the fixing frames are installed on the catwalk support cable and the catwalk guardrail cable, the fixing frames are slidably connected to the catwalk support cable and the catwalk guardrail cable, so that the netting fixed on the fixing frames slides along the catwalk support cable and the catwalk guardrail cable.

[0007] By adopting the above technical solution, the catwalk mesh is prefabricated first, reducing the work of laying the mesh sequentially from the end of the catwalk support cable to the middle and then fixing the stair rails to the mesh, which improves the efficiency of catwalk construction. Then, the fixing frame is installed on the catwalk support cable and the catwalk guardrail cable, and the mesh is then installed on the fixing frame. By setting the fixing frame to slide along the catwalk support cable and the catwalk guardrail cable, the mesh fixed to the fixing frame slides towards the middle of the catwalk support cable, reducing the manual work of carrying the mesh towards the middle of the catwalk support cable, further improving the efficiency of catwalk construction, and reducing manpower consumption. Meanwhile, by using a fixed frame to transport the catwalk mesh to the middle position of the catwalk load-bearing cable, and simultaneously transporting the catwalk guardrail to the middle position of the catwalk load-bearing cable, the situation of installing the mesh to the catwalk load-bearing cable first and then to the catwalk guardrail cable is reduced, which greatly improves the construction safety of the catwalk.

[0008] Preferably, the fixing frame consists of guardrails for installation onto the catwalk guardrail cables and load-bearing bars for installation onto the catwalk load-bearing cables, the guardrails and the load-bearing bars being fixedly connected using screws and nuts.

[0009] By adopting the above technical solution, the fixed frame structure is simple, reducing the load on the catwalk load-bearing cables and preventing overloading of the catwalk load-bearing cables due to the large number and weight of the fixed frames. This also helps reduce the cost of manufacturing the fixed frames, thereby reducing the overall cost of catwalk construction. Furthermore, using screws and nuts to fix the guardrails and load-bearing bars simplifies the fixing process, further improving the efficiency of catwalk construction. Additionally, installing the load-bearing bars onto the mesh first, then the guardrails onto the catwalk guardrail cables, and finally the load-bearing bars onto the catwalk load-bearing cables and guardrails, reduces the work of installing the fixed frames onto the catwalk load-bearing cables and guardrail cables, and then installing the mesh onto the fixed frames. This reduces the time spent working on the catwalk load-bearing cables, further improving the efficiency of catwalk construction.

[0010] Preferably, the load-bearing rod has a recessed load-bearing groove, and the load-bearing rod is also rotatably provided with a load-bearing buckle. One end of the load-bearing buckle is rotatably connected to the load-bearing rod, and the other end is connected to the load-bearing rod using screws and nuts. The load-bearing buckle also has a recessed load-bearing groove. When the load-bearing buckle and the load-bearing rod are fixed with screws, the load-bearing rod and the load-bearing buckle clamp the catwalk load-bearing cable, and the catwalk load-bearing cable is located in the load-bearing groove and the load-bearing groove.

[0011] The guardrail has a recessed guardrail groove, and the guardrail is also rotatably equipped with a guardrail buckle. One end of the guardrail buckle is rotatably connected to the guardrail, and the other end is connected to the guardrail using screws and nuts. The guardrail buckle also has a recessed guardrail groove. When the guardrail buckle and the guardrail are fixed with screws, the guardrail and the guardrail buckle clamp the catwalk guardrail cable, and the catwalk guardrail cable is located in the guardrail groove and the guardrail slot.

[0012] By adopting the above technical solution, after placing the load-bearing rods into the catwalk load-bearing cables, the position of the load-bearing rods is adjusted so that the catwalk load-bearing cables are engaged in the load-bearing grooves. Screws and nuts are then used to fix the load-bearing buckles and load-bearing rods, thus clamping the catwalk load-bearing cables together and strengthening the connection between them. Similarly, after placing the guardrails into the catwalk guardrail cables, the position of the guardrails is adjusted so that the catwalk guardrail cables are engaged in the guardrail grooves. Screws and nuts are then used to fix the guardrail buckles and guardrails together, thus clamping the catwalk guardrail cables together and strengthening the connection between them. This achieves the installation of the fixed frame into the catwalk load-bearing cables and catwalk guardrail cables. The operation is simple, improving the work efficiency of construction workers in installing the fixed frame, thereby further improving the efficiency of catwalk construction. Furthermore, by unscrewing the screws used to fix the load-bearing rods and load-bearing buckles, as well as those used to fix the guardrails and guardrail buckles, the fixing holes can be removed, making the operation simple and facilitating the disassembly of the catwalk.

[0013] Secondly, this application provides a construction method for a rapid segmented sliding laying device for catwalk mesh, employing the following technical solution:

[0014] A construction method for a rapid segmented sliding laying device for catwalk mesh includes the following steps:

[0015] Step S1: Prefabricate the catwalk surface netting for laying the catwalk load-bearing cables and catwalk guardrail cables, and install step poles and load-bearing poles onto the surface netting;

[0016] Step S2: Install guardrails onto the catwalk guardrail cables;

[0017] Step S3: Install the mesh onto the guardrail and use screws and nuts to fix the load-bearing rods and guardrails to the mesh to form a fixed frame. Then push the fixed frame toward the middle of the catwalk load-bearing cable along the length direction. Repeat the above steps until the mesh covers the catwalk load-bearing cable.

[0018] Step S4: Tie and secure the face netting and catwalk load-bearing cables, face netting and catwalk guardrail cables, and adjacent fixed frames at the midpoint along the length direction from the main tower to the catwalk load-bearing cables;

[0019] Step S5: After the catwalk is used, remove the fixing frame and the face net.

[0020] By adopting the above technical solution, the step ladders are installed onto the catwalk surface first, reducing the work of installing the catwalk surface after installing the catwalk load-bearing cables, thus greatly reducing the time required to construct the catwalk. Simultaneously, the load-bearing bars are installed onto the catwalk surface first, followed by the guardrails onto the catwalk guardrail cables, and then the load-bearing bars onto the catwalk load-bearing cables and guardrails. This reduces the work of installing the fixing frames onto the catwalk load-bearing cables and guardrail cables, and then installing the catwalk surface onto the fixing frames, thereby reducing the time spent working on the catwalk load-bearing cables and further improving the efficiency of catwalk construction. Connecting adjacent fixing frames reduces the possibility of the fixing frames sliding along the catwalk load-bearing cables and guardrail cables during worker movement, which helps improve construction safety during catwalk construction.

[0021] Preferably, in step S3, the mesh is installed onto the guardrail, one end of the mesh is fixed to the guardrail, and the load-bearing rod and guardrail fixed to one end of the mesh are fixed with screws and nuts. Then, the fixing frame is pushed towards the middle position of the catwalk load-bearing cable along the length direction. Then, the current guardrail is installed onto the catwalk guardrail. Then, the other end of the mesh is fixed to the current guardrail, and the load-bearing rod and guardrail fixed to one end of the mesh are fixed with screws and nuts. Then, the fixing frame is pushed towards the middle position of the catwalk load-bearing cable along the length direction. The above steps are repeated until the mesh covers the catwalk load-bearing cable.

[0022] By adopting the above technical solution, the mesh is laid towards the middle of the catwalk support cables using a fixed frame until it covers the cables. The mesh is then fixed to the catwalk support cables and catwalk guardrail cables. This reduces the need for manual handling of the mesh when laying it from the main tower towards the middle of the catwalk support cables, as it is previously obstructed by existing mesh. This further improves the efficiency of catwalk construction and reduces manpower consumption. It also reduces the situation where the uniform width of the prefabricated mesh makes it difficult for the next mesh to pass through the current one when laying it from the main tower towards the middle of the catwalk support cables.

[0023] Preferably, in step S3, a mesh is installed on the guardrail, one end of the mesh is fixed to the guardrail, and screws and nuts are used to fix the load-bearing rod and guardrail fixed to one end of the mesh. Then, the fixing frame is pushed towards the middle position of the catwalk load-bearing cable along the length direction. Then, the current guardrail is installed on the catwalk guardrail. Then, the other end of the mesh is fixed to the current guardrail, and screws and nuts are used to fix the load-bearing rod and guardrail fixed to one end of the mesh. Next, sandbags are hung on the current load-bearing rod. Then, the fixing frame is pushed towards the middle position of the catwalk load-bearing cable along the length direction. The above steps are repeated until the mesh covers the catwalk load-bearing cable.

[0024] By adopting the above technical solution, sandbags are used to increase the weight of the fixing frame, making it easier for the fixing frame and the netting to slide towards the catwalk support cable under the action of gravity. This reduces the situation where the fixing frame and the netting, due to their light weight, would stop due to friction between the support bar and the catwalk support cable, as well as the guardrail bar and the catwalk guardrail cable during the sliding process. This reduces the accumulation of the fixing frame and netting in the middle position away from the catwalk support cable, thus reducing the areas not covered by the netting when the netting is laid manually using the fixing frame, and further improving the efficiency of catwalk construction.

[0025] Preferably, in step S3, a mesh is installed on the guardrail, one end of the mesh is fixed to the guardrail, and screws and nuts are used to fix the load-bearing rod and guardrail fixed to one end of the mesh. Then, the fixing frame is pushed towards the middle position along the length of the catwalk load-bearing cable. Then, the current guardrail is installed on the catwalk guardrail. Then, the other end of the mesh is fixed to the current guardrail, and screws and nuts are used to fix the load-bearing rod and guardrail fixed to one end of the mesh. Next, sandbags are hung on the current load-bearing rod. Then, the fixing frame is pushed towards the middle position along the length of the catwalk load-bearing cable. The mesh is laid from both ends of the catwalk load-bearing cable towards the middle position using the walkway frame. The above steps are repeated until the mesh covers the catwalk load-bearing cable.

[0026] By adopting the above technical solution, the catwalk support netting is laid from both ends of the catwalk support cable to the middle position of the catwalk support cable using the walkway frame. At the same time, the weight of the walkway frame is increased by sandbags, reducing the need for machines to drive the walkway frame to slide. This reduces the cost of purchasing equipment to drive the fixed frame to slide and lowers the cost of making the catwalk.

[0027] Preferably, in step S5, after the catwalk is used, the fixed frames connected in the middle of the catwalk are disconnected first, and then the netting is disconnected from the catwalk load-bearing cable and the catwalk guardrail cable from the middle of the catwalk along the length direction to both ends of the catwalk in sequence. Then the fixed frames are pulled to both ends of the catwalk, and the fixed frames pulled to the end of the catwalk load-bearing cable and adjacent to it are disconnected.

[0028] By adopting the above technical solution, the catwalk is pulled towards the main tower from both ends using a drive mechanism. Compared to disassembling the walkway frame and mesh on the catwalk's load-bearing cables, disassembling them on the main tower is safer. Simultaneously, pulling the walkway frame and mesh to the main tower via the drive mechanism facilitates the binding work after disassembling the fixed frames and mesh by construction personnel. This makes it easier to hoist the disassembled fixed frames and mesh to the ground, reducing the need for construction personnel to tidy up the disassembled fixed frames and mesh on the remaining parts of the catwalk after disassembling them, thus promoting rapid disassembly of the catwalk.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By setting up walkway frames and detachably installing these frames on the catwalk support cables and guardrail cables, the work of sequentially laying the mesh from the end of the support cables towards the middle and then fixing the stair rails to the mesh is reduced, thus improving the efficiency of catwalk construction. After installing the fixing frames along the support cables and guardrail cables, the frames can slide, allowing the mesh fixed to the frames to slide towards the middle of the support cables. This reduces the need for manual handling of the mesh, further improving catwalk construction efficiency and reducing manpower consumption.

[0031] 2. By setting the installation of the step bars and load-bearing bars to the catwalk surface first, the work of installing the catwalk surface after installing the catwalk load-bearing cables and then installing the step bars to the surface is reduced, greatly reducing the time for constructing the catwalk. At the same time, the work of installing the fixed frame after installing the catwalk load-bearing cables and catwalk guardrail cables and then installing the catwalk surface after installing the fixed frame is reduced, thereby reducing the time spent working on the catwalk load-bearing cables and further improving the efficiency of catwalk construction.

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] Example 1

[0041] This application discloses a rapid segmented sliding laying device for catwalk mesh. (Refer to...) Figure 1 as well as Figure 2 The rapid segmented sliding installation device for the catwalk netting 2 includes catwalk support cables 11 for supporting the catwalk, catwalk guardrail cables 12 for supporting the catwalk railings, and several fixing frames 3 set on the catwalk support cables 11 for fixing the catwalk netting 2. In this embodiment, there are eight catwalk support cables 11 and two catwalk guardrail cables 12. In this embodiment, there are four fixing frames 3, with two fixing frames 3 forming a group, and each group of fixing frames 3 fixing both ends of a section of the netting 2 along its length. The fixing frame 3 consists of guardrail bars 32 detachably installed on the catwalk guardrail cables 12 and load-bearing rods 31 detachably installed on the catwalk support cables 11. In this embodiment, both the guardrail bars 32 and the load-bearing rods 31 are angle steel. There are two guardrail bars 32, and one end of each guardrail bar 32 along its length is fixed to both ends of the load-bearing rod 31 along its length using screws and nuts.

[0042] The waist plate of the load-bearing rod 31 has a recessed load-bearing groove 311. The bottom of the load-bearing groove 311 is semi-circular and the diameter of the bottom of the load-bearing groove 311 is larger than the diameter of the catwalk load-bearing cable 11. In this embodiment, each load-bearing rod 31 has eight recessed load-bearing grooves 311. The eight load-bearing grooves 311 are used to fit onto the eight catwalk load-bearing cables 11 respectively, and to secure the load-bearing rod 31 onto the catwalk load-bearing cables 11. Four load-bearing grooves 311 form a group, and the two groups of load-bearing grooves 311 are located at both ends of the load-bearing rod 31 along its length, and both groups of load-bearing grooves 311 are located between the connection points of the two guardrail bars 32 and the load-bearing rod 31.

[0043] Reference Figure 3 as well as Figure 4 The load-bearing rod 31 is also rotatably connected to a load-bearing buckle 312. The load-bearing buckle 312 is rectangular and there are eight load-bearing buckles 312. One side of each of the eight load-bearing buckles 312 in the width direction is recessed with a load-bearing groove 3121 for engaging the waist plate of the load-bearing rod 31. The bottom of the groove and one end along the length direction of the groove of the load-bearing groove 3121 penetrate through the bottom of the groove.

[0044] Reference Figure 3 as well as Figure 4One end of the load-bearing buckle 312 is rotatably connected to the load-bearing rod 31 via a load-bearing rotating rod 3123 along its length, and the other end is fixed to the load-bearing rod 31 with screws and nuts. The load-bearing rotating rod 3123 passes through the waist plate of the load-bearing buckle 312 and the load-bearing rod 31. The load-bearing buckle 312 has a load-bearing groove 3122 recessed along its length and on the side near the load-bearing rod 31. The bottom of the load-bearing groove 3122 is semi-circular, and the diameter of the bottom of the load-bearing groove 3122 is the same as the diameter of the bottom of the load-bearing groove 311. When the load-bearing buckle 312 and the load-bearing rod 31 are fixed with screws and nuts, the waist plate of the load-bearing rod 31 is inserted into the eight load-bearing slots 3121, the eight load-bearing grooves 3122 and the eight load-bearing slots 311 are spliced ​​together to form eight circular holes, and the eight catwalk load-bearing cables 11 are respectively located in the eight circular holes formed by the eight load-bearing grooves 3122 and the eight load-bearing slots 311, so that the load-bearing rod 31 is slidably connected to the catwalk load-bearing cables 11.

[0045] Reference Figure 3 as well as Figure 5 The guardrail 32 has a recessed guardrail groove 321 on its waist plate. The bottom of the guardrail groove 321 is semi-circular and its diameter is larger than that of the cat walkway guardrail cable 12. The guardrail groove 321 is located at the end of the guardrail 32 away from the guardrail 32. The guardrail 32 is also rotatably connected to a guardrail buckle 322. The guardrail buckle 322 is rectangular. Each of the eight guardrail buckles 322 has a recessed guardrail locking groove 3221 on one side of its width direction for engaging the waist plate of the guardrail 32. The bottom of the guardrail locking groove 3221 and one end of its length direction penetrate through the bottom of the groove.

[0046] Reference Figure 3 as well as Figure 5 One end of the guardrail buckle 322 is rotatably connected to the guardrail rod 32 along its length using a guardrail lever 3223, and the other end is fixed to the guardrail rod 32 using screws and nuts. The guardrail lever 3223 passes through the waist plate of both the guardrail buckle 322 and the guardrail rod 32. A guardrail groove 3222 is recessed along the length of the guardrail buckle 322 and near the guardrail rod 32. The bottom of the guardrail groove 3222 is semi-circular, and the diameter of the bottom of the guardrail groove 3222 is the same as the diameter of the bottom of the guardrail slot 321. When the guardrail buckle 322 and the guardrail rod 32 are fixed using screws and nuts, the waist plate of the load-bearing rod 31 is inserted into the guardrail slot 3221. The guardrail groove 3222 and the guardrail slot 321 form a circular hole, and the catwalk guardrail cable 12 is located in the circular hole formed by the guardrail groove 3222 and the guardrail slot 321, allowing the guardrail rod 32 to slide on the catwalk guardrail cable 12.

[0047] Reference Figure 3 as well as Figure 5The guardrail 32 also has three guardrail fixing holes 323 on its waist plate, which are convenient for construction workers to use binding wire to fix the guardrail 32 and the mesh 2. The three guardrail fixing holes 323 are located on the upper part of the length direction of the guardrail 32. The load-bearing bar 31 also has six load-bearing fixing holes 313 on its waist plate, which are convenient for construction workers to use binding wire to fix the load-bearing bar 31 and the mesh 2. Three load-bearing fixing holes 313 form a group, and the load-bearing fixing holes 313 in the same group are located between adjacent load-bearing grooves 311 in the same group.

[0048] The implementation principle of the rapid segmented sliding laying device for catwalk mesh in this embodiment is as follows:

[0049] First, prefabricate the surface net 2 for laying the cat walkway, install the step rods 21 on the surface net 2, and use binding wire to pass through the load-bearing fixing holes 313 to install the two load-bearing rods 31 at both ends of the surface net 2 along the length direction.

[0050] When it is necessary to lay the netting 2 on the catwalk load-bearing cable 11 and the catwalk guardrail cable 12, first install the two guardrail bars 32 on the two catwalk guardrail cables 12 respectively: put the two guardrail bars 32 on the two catwalk guardrail cables 12 respectively, so that the two catwalk guardrail cables 12 are respectively inserted into the two guardrail slots 321; then rotate the guardrail buckle 322, and use screws and nuts to fix one end of the guardrail buckle 322 to the guardrail bar 32, so that the guardrail bar 32 is slidably connected to the catwalk guardrail cable 12.

[0051] Then, install the load-bearing rods 31 onto the catwalk load-bearing cables 11: Place the load-bearing rods 31, installed at one end of the netting 2 along its length, onto the catwalk load-bearing cables 11, so that the eight catwalk load-bearing cables 11 are respectively inserted into the eight load-bearing slots 311. Then, use screws and nuts to fix the guardrails 32 and the load-bearing rods 31, forming a fixed frame 3. Next, use screws and nuts to fix eight load-bearing buckles 312 to the load-bearing rods 31, so that the load-bearing rods 31 are slidably connected to the catwalk load-bearing cables 11, thereby allowing the fixed frame 3 to slidably connect the catwalk load-bearing cables 11 and the catwalk guardrail cables 12. Finally, use binding wire to fix the netting 2 to the guardrails 32 through the guardrail fixing holes 323.

[0052] Next, install the fixing frame 3 at the other end of the netting 2: continue installing guardrails 32 onto the two catwalk load-bearing cables 11, then push the previous fixing frame 3 towards the middle of the catwalk load-bearing cable 11 along its length until the end of the netting 2 without the fixing frame 3 is flush with the end of the catwalk guardrail cable 12. Then, use screws and nuts to fix the load-bearing rod 31 and guardrail 32 at the other end of the netting 2. Then, put the load-bearing rod 31 onto the catwalk load-bearing cable 11, so that the eight catwalk load-bearing cables 11 are respectively inserted into the eight load-bearing slots 311. Then, use screws and nuts to fix the guardrail 32 and the load-bearing rod 31 to form the fixing frame 3. Then, use binding wire to fix the netting 2 to the guardrail 32 through the guardrail fixing holes 323. Then, push the netting 2, which is slidably connected to the catwalk load-bearing cable 11 and the catwalk guardrail cable 12 through the fixing frame 3, towards the middle of the catwalk load-bearing cable 11 along its length. Repeat the above steps until the netting 2 covers the catwalk load-bearing cable 11.

[0053] Using binding wires, bind and secure the catwalk load-bearing cable 11 from both ends along the length of the catwalk load-bearing cable 11 to the middle position along the length of the catwalk load-bearing cable 11, the catwalk load-bearing cable 12, and the adjacent fixed frame 3.

[0054] By setting up load-bearing rods 31, load-bearing buckles 312, guardrails 32, and guardrail buckles 322, the catwalk mesh 2 is slidably connected to the catwalk load-bearing cable 11 and the catwalk guardrail cable 12 via the fixing frame 3. This allows the catwalk mesh 2 to slide towards the middle position along the length of the catwalk load-bearing cable 11, reducing the manual pushing work of the catwalk mesh 2 and improving the efficiency of catwalk construction. Simultaneously, by setting one end of the load-bearing buckle 312 to be rotatably connected to the load-bearing rod 31 and the other end to be fixedly connected to the load-bearing rod 31 with screws and nuts, one end of the guardrail buckle 322 to be rotatably connected to the guardrail cable 32 and the other end to be fixedly connected to the guardrail cable 32, and the load-bearing rod 31 and the guardrail cable 32 to be fixedly connected with screws and nuts, the time spent installing the fixing frame 3 on the catwalk load-bearing cable 11 and the catwalk guardrail cable 12 is reduced, further improving the efficiency of catwalk construction.

[0055] Example 2

[0056] This application discloses a construction method for a rapid segmented sliding laying device for catwalk mesh, including the following steps:

[0057] Step S1: Prefabricate the catwalk surface net 2 for laying the catwalk load-bearing cables 11 and catwalk guardrail cables 12, and install the step ladders 21 and load-bearing bars 31 onto the surface net 2. The specific operation steps are as follows:

[0058] Step S11: Cut the mesh 2 according to the drawing, and use the binding wire to tie the step rod 21 to the mesh 2 used to lay the catwalk load-bearing cable 11.

[0059] Step S12: Using binding wire, pass through the load-bearing fixing hole 313 and tie two load-bearing rods 31 to both ends of the netting 2 used for laying the load-bearing cable 11 of the cat walkway along the length direction.

[0060] Step S13: Use binding wire to tie and fix the netting 2 used for laying the catwalk guardrail cable 12 and the netting 2 used for laying the catwalk load-bearing cable 11.

[0061] Step S2: Place the two guardrail bars 32 onto the two catwalk guardrail cables 12 respectively, so that the two catwalk guardrail cables 12 are respectively inserted into the two guardrail slots 321; then rotate the guardrail buckle 322 and use screws and nuts to fix one end of the guardrail buckle 322 to the guardrail bar 32, so that the guardrail bar 32 is slidably connected to the catwalk guardrail cable 12.

[0062] Step S3: Install the face net 2 onto the guardrail 32, and use screws and nuts to fix the load-bearing rod 31 and guardrail 32 fixed on the face net 2 to form a fixing frame 3. Then push the fixing frame 3 towards the middle position of the catwalk load-bearing cable 11 along the length direction. Repeat the above steps until the face net 2 covers the catwalk load-bearing cable 11. The specific operation steps are as follows:

[0063] Step S31: The load-bearing rod 31, installed at one end of the catwalk 2 along its length, is fitted onto the catwalk load-bearing cable 11, so that the eight catwalk load-bearing cables 11 are respectively inserted into the eight load-bearing slots 311. Then, the guardrail 32 and the load-bearing rod 31 are fixed with screws and nuts to form a fixed frame 3. Next, eight load-bearing buckles 312 are fixed to the load-bearing rod 31 with screws and nuts, so that the load-bearing rod 31 is slidably connected to the catwalk load-bearing cable 11, thereby allowing the fixed frame 3 to slidably connect to the catwalk load-bearing cable 11 and the catwalk guardrail cable 12.

[0064] Step S32: Use binding wire to fix the face net 2 to the guardrail 32 through the guardrail fixing hole 323.

[0065] Step S33: Push the fixed frame 3 towards the middle of the catwalk load-bearing cable 11 along the length direction until the end of the net 2 without the fixed frame 3 is flush with the end of the catwalk guardrail cable 12. Then use the hook to fix the end of the net 2 without the fixed frame 3 to the main tower 4.

[0066] Step S34: Install the current guardrail 32 onto the cat walkway guardrail 32.

[0067] Step S34: Use screws and nuts to fix the load-bearing rod 31 and guardrail 32 at the end of the mesh 2 where the fixing frame 3 is not installed, to form the current fixing frame 3.
