Description

Technical Field

[0001] This disclosure relates to the field of catwalk traction technology for suspension bridges, and more specifically, to a catwalk laying traction device and method. Background Technology

[0002] With the advancement of technology and economic development, my country's infrastructure construction has expanded significantly, including bridge construction. Among these, suspension bridges have the largest spans. The catwalk of a suspension bridge is located directly beneath the main cable and runs along it. As temporary high-altitude scaffolding during suspension bridge construction, the catwalk is a crucial structure related to the main cable system and the entire superstructure of the suspension bridge. Currently, the laying of catwalks typically involves setting up fixed winches on both sides of the riverbank to pull the catwalk cables one by one.

[0003] However, existing construction methods (see Chinese patent document: CN110438880B) require the use of manual machinery (e.g., tractors, towing vessels) to pull the catwalk cables one by one from one bank to the other, and then using a lifting device to raise the catwalk cables to the designed position. This method is unsuitable for construction sites that are not navigable or accessible by vehicles. For example, this method is not applicable when the area between the two banks is a non-navigable river or an inaccessible mountainous area. Furthermore, existing construction methods require the use of manual machinery and lifting devices, making the construction process complex and inefficient. Summary of the Invention

[0004] To address the technical problems existing in the related technologies, the purpose of this disclosure is to provide a catwalk laying traction device and method.

[0005] According to one aspect of this disclosure, a catwalk laying traction device is provided, including a load-bearing traction cable, a plurality of mounting frames, a plurality of locking mechanisms, a plurality of supporting mechanisms, and two traction mechanisms respectively disposed on a first bank and a second bank;

[0006] The mounting frames are arranged in pairs, and each pair of mounting frames is used to install the two sides on the main tower and the two sides on the bank piers. The mounting frame includes a first support leg and a second support leg that are connected to each other. The first support leg and the second support leg enclose a first cavity and a second cavity that are connected to each other, and the first cavity is located above the second cavity.

[0007] The load-bearing traction cables are sequentially threaded through the first cavity of all the mounting frames and form a ring structure;

[0008] One end of the locking mechanism is mounted on the load-bearing traction cable, and the other end of the locking mechanism is used to fix the catwalk cable. The lateral dimension of the locking mechanism is smaller than the lateral dimension of the second cavity so that the locking mechanism can pass through the second cavity. One end of the supporting mechanism is mounted on the load-bearing traction cable, and the other end of the supporting mechanism is used to support the catwalk cable. The lateral dimension of the supporting mechanism is smaller than the lateral dimension of the second cavity so that the supporting mechanism can pass through the second cavity.

[0009] The traction mechanism located on the first bank is connected to the portion of the load-bearing traction cable near the second bank, and the traction mechanism located on the second bank is connected to the portion of the load-bearing traction cable near the first bank, so that the two traction mechanisms can drive the load-bearing traction cable to rotate circumferentially along the load-bearing traction cable.

[0010] As an optional technical solution, the mounting bracket further includes a rotating component, which includes a rotating shaft extending in a vertical direction and multiple rotating rods extending in a horizontal direction. The rotating shaft is rotatably mounted on the first support leg, and the multiple rotating rods are arranged circumferentially around the rotating shaft. One end of each of the multiple rotating rods is connected to the rotating shaft, and the length of the rotating rod is less than or equal to the length of the connection between the first cavity and the second cavity.

[0011] As an optional technical solution, multiple rotating rods are evenly spaced.

[0012] As an optional technical solution, the support mechanism includes an installation component, a connector, and a support component. The installation component is used to connect with the load-bearing traction cable. One end of the connector is connected to the installation component, and the other end of the connector is connected to the middle of the support component. The support component has a plurality of support grooves evenly spaced on it, and the support grooves are used to support the catwalk cable.

[0013] As an optional technical solution, the locking mechanism includes an installation ring, a first connecting rod, a second connecting rod, a third connecting rod, and an installation rod. The installation ring is used to fit onto the load-bearing traction cable. One end of the first connecting rod is connected to the installation ring, and the other end of the first connecting rod is connected to the second connecting rod and the third connecting rod. The second connecting rod, the third connecting rod, and the installation rod form a triangular structure. The installation rod is used to install the catwalk cable.

[0014] As an optional technical solution, the length of the second connecting rod is equal to the length of the third connecting rod, and the mounting rod extends in the horizontal direction.

[0015] As an optional technical solution, the mounting rod body is provided with a plurality of first through holes spaced apart. The first through holes are used for the catwalk cable to pass through, and the radial dimension of the first through holes is greater than or equal to the radial dimension of the catwalk cable.

[0016] As an optional technical solution, the mounting rod includes a first rod and a second rod. The two ends of the first rod are respectively used to connect the second connecting rod and the third connecting rod. The second rod includes a first part and a second part. The first part is installed at the bottom of the first rod and a first groove corresponding to the first through hole is formed on the first part. The second part is rotatably installed on the first rod and located above the first part. A second groove corresponding to the first through hole is formed on the second part.

[0017] The mounting rod includes a locked state and an unlocked state. In the locked state, the first part and the second part are abutting each other and are detachably connected. The first groove and the second groove together enclose a second through hole that is coaxial with the first through hole. The radial dimension of the second through hole is smaller than the radial dimension of the catwalk cable. In the unlocked state, the first part and the second part are separated from each other.

[0018] As an optional technical solution, a locking groove and a first locking block are formed at the end of the first part away from the rotation axis of the second part. The locking groove is disposed between the locking block and the first rod body. A second locking block that matches the locking groove is formed on the second part. A locking notch that matches the first locking block is formed on the second part.

[0019] In the locked state, the second locking block is accommodated in the locking groove, and the first locking block is accommodated in the locking notch.

[0020] According to another aspect of this disclosure, a catwalk laying and traction method is provided, applied to the catwalk laying and traction device described in any of the above-mentioned technical solutions of this disclosure, the catwalk laying and traction method comprising:

[0021] Pairs of mounting frames are installed on both sides of the main tower and on both sides of the bank piers. The load-bearing traction cable is then sequentially inserted into the first cavity. At least one locking mechanism is installed on both sides of the load-bearing traction cable near the banks, and a support mechanism is installed on the load-bearing traction cable at certain intervals.

[0022] On both sides, the extended ends of the catwalk cables are installed onto the locking mechanisms. The traction mechanism is then activated, causing the load-bearing traction cable to rotate around it. As the catwalk cables move along with the load-bearing traction cable, they are placed into the support mechanism, which moves synchronously with the load-bearing traction cable. The traction mechanism is stopped once the catwalk cables from both sides reach their respective preset positions on the opposite bank.

[0023] Release the end of the catwalk cable from the locking mechanism and anchor it to the anchoring device. Remove the middle part of the catwalk cable from the support mechanism and install it into the catwalk cable saddle.

[0024] Through the above technical solution, on the one hand, the catwalk laying traction device of this disclosure eliminates the need for manual machinery to pull the catwalk cable between the two banks, thus making it suitable for situations where navigation or passage between the two banks is not possible. On the other hand, the load-bearing traction cable of this disclosure can act as a guiding device, providing guidance for the locking mechanism and the supporting mechanism. The locking mechanism can be relatively fixed to one end of the catwalk cable, allowing the catwalk cable to gradually move to the opposite bank under the drive of the locking mechanism. At the same time, the supporting mechanism can lift the catwalk cable during its movement, which helps to improve the stability of the catwalk cable during movement. In this way, the traction and laying of the catwalk cable can be completed very conveniently and quickly. Furthermore, the traction mechanism of this disclosure is connected to both ends of the annular load-bearing traction cable, and can act as a driving device for the circumferential rotation of the load-bearing traction cable, thereby realizing the traction and laying process of the catwalk cable between the two banks. On another note, the construction process disclosed herein does not require manual or mechanical traction of the catwalk cables, nor does it require lifting machinery to raise the catwalk cables. Furthermore, it enables the simultaneous laying and traction of the corresponding upstream and downstream catwalk cables in one go, which effectively simplifies the construction process, improves construction efficiency, and reduces construction difficulty.

[0025] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0039] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0040] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" refer to the upper and lower as defined in the operating state of the catwalk laying and traction device of this disclosure. Terms such as "first" and "second" are used only to distinguish one element from another and do not imply any order or importance. Furthermore, the directional terms used above are for the convenience of describing this disclosure simply and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting this disclosure.

[0041] To facilitate a clearer and more accurate understanding of the technical solutions disclosed herein by those skilled in the art, the existing related technologies will be described in more detail below.

[0042] In existing related technologies, when laying catwalk cables, one end of the catwalk cable is first installed on one bank, and then the other end of the catwalk cable is pulled to the opposite bank using manual machinery (e.g., towing vehicles, towing ships, etc.). Then, lifting machinery is used to lift the catwalk cable to the designed position, and the above operation is repeated until all catwalk cables are laid.

[0043] However, the above construction methods will no longer be applicable when there are no navigational conditions for towing vessels or passage for towing vehicles, such as when the water between the two banks is shallow and contains many large boulders, or when the roads between the two banks are rugged or entirely farmland.

[0044] Even when navigation or traffic conditions are met, the above construction methods still have drawbacks such as complex construction procedures and long construction periods.

[0045] In view of this, the present disclosure provides a catwalk cable laying traction device and method, which is not only applicable to situations where there is no navigation or passage between the two banks, but also has the advantages of simple construction procedures and short construction period.

[0046] The technical solution of this disclosure will be described in more detail below with reference to the accompanying drawings.

[0047] According to one aspect of this disclosure, such as Figures 1 to 10As shown, this disclosure provides a catwalk traction device 100, including a load-bearing traction cable 1, several mounting frames 2, several locking mechanisms 3, several supporting mechanisms 4, and two traction mechanisms 5 respectively disposed on the first bank and the second bank; the mounting frames 2 are arranged in pairs, each pair of mounting frames 2 is used to install on both sides of the main tower 200 and both sides of the bank side piers 300, the mounting frame 2 includes a first support leg 21 and a second support leg 22 connected to each other, the first support leg 21 and the second support leg 22 enclosing a first cavity 23 and a second cavity 24 that are interconnected, and the first cavity 23 is located above the second cavity 24; the load-bearing traction cable 1 is sequentially passed through the first cavity 23 of all mounting frames 2 and forms a ring structure; one of the locking mechanisms 3... One end of the locking mechanism 3 is installed on the load-bearing traction cable 1, and the other end of the locking mechanism 3 is used to fix the catwalk cable 101. The lateral dimension of the locking mechanism 3 is smaller than the lateral dimension of the second cavity 24 so that the locking mechanism 3 can pass through the second cavity 24. One end of the supporting mechanism 4 is installed on the load-bearing traction cable 1, and the other end of the supporting mechanism 4 is used to support the catwalk cable 101. The lateral dimension of the supporting mechanism 4 is smaller than the lateral dimension of the second cavity 24 so that the supporting mechanism 4 can pass through the second cavity 24. The traction mechanism 5 located on the first bank is connected to the part of the load-bearing traction cable 1 near the second bank, and the traction mechanism 5 located on the second bank is connected to the part of the load-bearing traction cable 1 near the first bank so that the two traction mechanisms 5 can drive the load-bearing traction cable 1 to rotate circumferentially along the load-bearing traction cable 1.

[0048] Through the above technical solution, on the one hand, the catwalk laying traction device 100 of this disclosure eliminates the need for manual machinery to pull the catwalk cable 101 between the two banks, thus making it suitable for situations where navigation or passage between the two banks is not possible. On the other hand, the load-bearing traction cable 1 of this disclosure can serve as a guiding device, providing guidance for the locking mechanism 3 and the supporting mechanism 4. The locking mechanism 3 can be relatively fixed to one end of the catwalk cable 101, allowing the catwalk cable 101 to gradually move to the opposite bank under the drive of the locking mechanism 3. At the same time, the supporting mechanism 4 can lift the catwalk cable 101 during its movement, which helps to improve the stability of the catwalk cable 101 during its movement. In this way, the traction and laying of the catwalk cable 101 can be completed very conveniently and quickly. Furthermore, the traction mechanism 5 of this disclosure is connected to both ends of the annular load-bearing traction cable 1, and can serve as a driving device for the circumferential rotation of the load-bearing traction cable 1, thereby realizing the traction and laying process of the catwalk cable 101 between the two banks. On another note, the construction process disclosed herein does not require manual or mechanical traction of the catwalk cable 101, nor does it require lifting machinery to raise the catwalk cable 101. At the same time, it can simultaneously complete the laying and traction of the corresponding catwalk cables 101 upstream and downstream in one go, which can effectively simplify the construction process, improve construction efficiency, and reduce construction difficulty.

[0049] To facilitate understanding by relevant technical personnel, the working principle / process of the catwalk laying traction device 100 disclosed herein is explained below:

[0050] When laying the catwalk cable 101, first install the mounting frame 2 on the main tower 200, side pier 300, or the ground. Then, thread one end of the load-bearing traction cable 1 through the mounting frame 2, and connect the two ends of the load-bearing traction cable 1 to form a ring structure. Install the locking mechanism 3 on the portion of the load-bearing traction cable 1 near both banks, and install the supporting mechanism 4 at other positions on the load-bearing traction cable 1. Then, fix the extended end of the catwalk cable 101 to the locking mechanism 3. Activate the traction mechanisms 5 on both banks to drive the load-bearing traction cable 1 to rotate around its own circumference, thereby moving the locking mechanism 3 towards the opposite bank, and further moving the extended end of the catwalk cable 101 towards the opposite bank until the catwalk cable 101 reaches the designed position. Then, close the traction mechanism 5, detach the catwalk cable 101 from the locking mechanism 3 and the supporting mechanism 4, and then install the catwalk cable 101 into the catwalk cable saddle. In this way, the corresponding catwalk cables 101 on both the upstream and downstream sides are installed at once.

[0051] Furthermore, since the catwalk includes an upstream catwalk and a downstream catwalk, and each of the upstream and downstream catwalks includes multiple catwalk cables 101, the catwalk traction and laying device described in the above embodiment can be repeatedly used to achieve the traction and laying of all catwalk cables 101.

[0052] In one optional embodiment of this disclosure, such as Figures 3 to 5 As shown, the mounting bracket 2 of this disclosure may further include a rotating component 25. The rotating component 25 includes a rotating shaft 251 extending in the vertical direction and multiple rotating rods 252 extending in the horizontal direction. The rotating shaft 251 is rotatably mounted on the first support leg 21. The multiple rotating rods 252 are arranged at intervals around the rotating shaft 251, and one end of each of the multiple rotating rods 252 is connected to the rotating shaft 251. The length of the rotating rods 252 is less than or equal to the length of the connection between the first cavity 23 and the second cavity 24.

[0053] The rotating rod 252, configured in this way, can block the connection between the first cavity 23 and the second cavity 24, thus preventing the load-bearing traction cable 1 from slipping out of the first cavity 23 into the second cavity 24. This helps ensure that the load-bearing traction cable 1 remains continuously within the first cavity 23, and facilitates the continuous and smooth operation of the catwalk laying traction device 100 of this disclosure. Furthermore, the rotating rod 252, configured in this way, can rotate under the action of the locking mechanism 3 or the supporting mechanism 4 when passing through the second cavity 24, so that the locking mechanism 3 and the supporting mechanism 4 can pass smoothly through the mounting frame 2, thereby ensuring the continuous and reliable operation of the catwalk laying traction device 100 of this disclosure.

[0054] In one optional embodiment of this disclosure, such as Figure 5 As shown, the multiple rotating rods 252 of this disclosure can be evenly spaced. This helps to ensure that the force on the rotating member 25 is relatively balanced, and on the basis of reliably supporting the load-bearing traction cable 1, the locking mechanism 3 or the supporting mechanism 4 can pass smoothly through the second cavity 24.

[0055] In one optional embodiment of this disclosure, such as Figure 10 As shown, the support mechanism 4 of this disclosure may include an installation member 41, a connector 42, and a support member 43. The installation member 41 is used to connect with the load-bearing traction cable 1. One end of the connector 42 is connected to the installation member 41, and the other end of the connector 42 is connected to the middle of the support member 43. The support member 43 has a plurality of support grooves 431 evenly spaced on it, and the support grooves 431 are used to support the catwalk cable 101.

[0056] Thus, on the one hand, the supporting mechanism 4 of this disclosure has a simple structure and a small self-weight, which can effectively reduce the self-weight of the entire catwalk laying traction device 100, which is conducive to convenient construction; on the other hand, the supporting member 43 provided in this disclosure can simultaneously support multiple catwalk cables 101 through the supporting groove 431 provided thereon, and can maintain the smooth movement of multiple catwalk cables 101. In this way, it is beneficial to lay multiple catwalk cables 101 at one time, and also to effectively maintain the smooth movement of multiple catwalk cables 101, which is conducive to fast and convenient construction.

[0057] In one optional embodiment of this disclosure, such as Figures 6 to 9 As shown, the locking mechanism 3 of this disclosure may include a mounting ring 31, a first connecting rod 32, a second connecting rod 33, a third connecting rod 34, and a mounting rod 35. The mounting ring 31 is used to be sleeved on the load-bearing traction cable 1. One end of the first connecting rod 32 is connected to the mounting ring 31, and the other end of the first connecting rod 32 is connected to the second connecting rod 33 and the third connecting rod 34. The second connecting rod 33, the third connecting rod 34, and the mounting rod 35 form a triangular structure. The mounting rod 35 is used to install the catwalk cable 101.

[0058] Thus, on the one hand, the locking mechanism 3 of this disclosure can be quickly and stably installed onto the load-bearing traction cable 1 via the mounting ring 31. Simultaneously, the catwalk cable 101 can be installed via the mounting rod 35, enabling synchronous movement between the catwalk cable 101 and the load-bearing traction cable 1. On the other hand, the second connecting rod 33, the mounting rod 35, and the second connecting rod 33 form a stable and reliable triangular structure. This structure is not only relatively simple and has a strong load-bearing capacity, but also maintains the catwalk cable 101 installed on the mounting rod 35 in a relatively stable state during movement.

[0059] It is understood that the first connecting rod 32, the second connecting rod 33, the third connecting rod 34 and the mounting rod 35 of this disclosure can all be formed as hollow structures to further reduce the weight of the catwalk laying traction device 100 of this disclosure.

[0060] In one optional embodiment of this disclosure, the length of the second connecting rod 33 may be equal to the length of the third connecting rod 34, and the mounting rod 35 extends in the horizontal direction.

[0061] Thus, in this embodiment, the triangular structure formed by the second connecting rod 33, the second connecting rod 33 and the mounting rod 35 is an isosceles triangle structure, which can not only reliably fix the catwalk cable 101, but also effectively maintain the stability of the catwalk cable 101 during movement.

[0062] In one optional embodiment of this disclosure, such as Figures 6 to 9 As shown, the mounting rod 35 of this disclosure has a plurality of first through holes 351 spaced apart. The first through holes 351 are used for cat track cables 101 to pass through, and the radial dimension of the first through holes 351 is greater than or equal to the radial dimension of the cat track cables 101.

[0063] Thus, when it is necessary to fix the catwalk cable 101 to the locking mechanism 3, the extended end of the catwalk cable 101 can be passed through the first through hole 351, and then the other end can be fixed to the mounting rod 35 by a locking mechanism (e.g., a locking block, threaded fastener, etc.). In this way, the fixing method of the catwalk cable 101 is very simple and quick, which helps to simplify the construction process and improve construction efficiency.

[0064] In one optional embodiment of this disclosure, such as Figures 7 to 9As shown, the mounting rod 35 of this disclosure may include a first rod 352 and a second rod 353. The two ends of the first rod 352 are respectively used for connecting the second connecting rod 33 and the third connecting rod 34. The second rod 353 includes a first part 3531 and a second part 3532. The first part 3531 is mounted on the bottom of the first rod 352, and a first groove 3531a corresponding to the first through hole 351 is formed on the first part 3531. The second part 3532 is rotatably mounted on the first rod 352 and located at the first part 3531. Above, a second groove 3532a corresponding to the first through hole 351 is formed on the second part 3532; wherein, the mounting rod 35 includes a locked state and an unlocked state. In the locked state, the first part 3531 and the second part 3532 abut against each other and are detachably connected. The first groove 3531a and the second groove 3532a together enclose a second through hole coaxial with the first through hole 351. The radial dimension of the second through hole is smaller than the radial dimension of the catwalk cable 101. In the unlocked state, the first part 3531 and the second part 3532 are separated from each other.

[0065] Thus, when it is necessary to fix the cat track cable 101 to the locking mechanism 3, the unfolded end of the cat track cable 101 can be inserted through the first through hole 351, and then the first part 3531 and the second part 3532 can be adjusted to the locked state so that the cat track cable 101 can be quickly and reliably fixed to the locking mechanism 3.

[0066] Furthermore, it is understood that the mounting rod 35 of this disclosure may also include a buffer member disposed in the first groove 3531a and / or the second groove 3532a. In the locked state, the buffer member can not only enhance the fixing effect between the locking mechanism 3 and the catwalk cable 101, but also prevent damage to the catwalk cable 101 to a certain extent.

[0067] It should be noted that the buffer component disclosed herein can have various implementations. For example, it can be a rubber component, a plastic component, etc., and it can be ring-shaped, block-shaped, or spherical. This application does not specifically limit it in this regard.

[0068] In one optional embodiment of this disclosure, as shown in the figure Figure 9As shown, the first part 3531 of this disclosure may have a locking groove 3531b and a first locking block 3531c formed at the end away from the rotation axis 251 of the second part 3532. The locking groove 3531b is disposed between the locking block and the first rod 352. The second part 3532 has a second locking block 3532b that matches the locking groove 3531b and a locking notch 3532c that matches the first locking block 3531c. In the locked state, the second locking block 3532b is accommodated in the locking groove 3531b and the first locking block 3531c is accommodated in the locking notch 3532c.

[0069] In this way, the first part 3531 and the second part 3532 can be quickly locked and unlocked through the locking groove 3531b, the second locking block 3532b, the locking notch 3532c and the first locking block 3531c, which helps to simplify the construction process and improve the construction efficiency.

[0070] According to another aspect of this disclosure, a catwalk laying and traction method is provided, applied to the catwalk laying and traction device 100 in any of the above-described technical solutions of this disclosure. The catwalk laying and traction method includes:

[0071] Pairs of mounting frames 2 are installed on both sides of the main tower 200 and on both sides of the bank piers 300. The load-bearing traction cable is sequentially inserted into the first cavity 23. At least one locking mechanism 3 is installed on both sides of the load-bearing traction cable 1 near the banks, and a support mechanism 4 is installed on the load-bearing traction cable 1 at certain intervals.

[0072] In this embodiment, the number and spacing of the locking mechanisms 3 can be selected according to actual needs, as long as they can reliably and stably fix the catwalk cable 101. Similarly, the spacing of the supporting mechanisms 4 can be selected according to actual needs, and this disclosure does not impose specific limitations on it.

[0073] The extended ends of the catwalk cables 101 on both banks are installed onto the locking mechanism 3. The traction mechanism 5 is activated, causing the load-bearing traction cable 1 to rotate around it. As the catwalk cables 101 move with the load-bearing traction cable 1, the catwalk cables 101 are placed into the support mechanism 4, which moves synchronously with the load-bearing traction cable 1. The traction mechanism 5 is stopped after the catwalk cables 101 from both banks reach the preset positions on the opposite bank.
