Description

Technical Field

[0001] This application relates to the field of suspension bridge construction technology, and more specifically, to a device for segmented traction conversion of load-bearing cables. Background Technology

[0002] A suspension bridge is a bridge whose superstructure primarily consists of cables suspended from towers and anchored to both banks. Traditionally, suspension bridges are two-tower bridges, such as the Golden Gate Bridge in the United States and the Xihoumen Bridge in China. There are also three-tower suspension bridges, such as the Taizhou Yangtze River Bridge and the Yingwuzhou Yangtze River Bridge in China. Four-tower suspension bridges have also been considered in design, but due to the decrease in structural stiffness caused by the increased number of towers, there are no real-world examples of four-tower suspension bridges.

[0003] In existing technologies, the construction of suspension bridge deck systems requires the erection of catwalks for construction. Both the catwalk cables and the main cable strands need to be traction and installed via an overhead traction system. For suspension bridge construction in complex terrains, such as those spanning mountains, seas, or long-span rivers, the foundation support is relatively weak. The traction system, continuously erected between anchorages and towers, can be modified to be erected in segments, relying primarily on anchorages and towers as the traction load-bearing structures. However, segmented traction systems require switching the traction sections. If this is done manually, the high-altitude work is difficult and the risks are uncontrollable. Adding additional switching structures would complicate the traction system and increase construction costs. Utility Model Content

[0004] This application addresses the shortcomings of existing methods by proposing a device for segmented traction conversion of load-bearing cables, thereby solving the technical problems of uncontrollable risks to workers operating at heights or uncontrollable construction costs and reliability in related technologies.

[0005] This application provides a device for segmented traction conversion of a load-bearing cable, comprising: Set at the traction end of the load-bearing cable A group of traction heads and anchor heads, wherein the anchor head is configured as the end of the traction end, and each group of traction heads is sequentially defined as the first... Group traction head, first Group traction head to the first Group traction head, number The traction head is closest to the anchor head; , Take the integer part; No. Group traction head, first Group traction head, first The traction head and the anchor head are sequentially and individually connected to the corresponding traction cables of the traction system, so as to pull the traction end through the corresponding traction cables.

[0006] Specifically, the main technical concept of this application lies in setting up a traction end of the load-bearing cable. The traction head and anchor head sequentially pull the load-bearing cable in their respective traction sections. This eliminates the need to modify the segmented traction system; the load-bearing cable can be switched between adjacent sections simply by changing the traction head and anchor head, avoiding the high-altitude work risks associated with manual cable switching. Furthermore, this application can be used with simple segmented traction systems, avoiding the introduction of complex switching structures and mitigating the technical problems of decreased reliability caused by complex structures, thus ensuring the reliability and low cost of traction construction.

[0007] Furthermore, in the twin-tower suspension bridge, ; Or, in the Three-Tower Suspension Bridge, .

[0008] It is worth explaining that, Used to represent The number of segments in the traction system required by the traction head and anchor head, such as a double-tower suspension bridge divided into 2... The paragraph, that is, the application needs to pass The traction head and anchor head are segmented and switched within a three-segment traction system, respectively used for switching the traction segment from the first anchorage to the first tower, from the first tower to the second tower, and from the second tower to the second anchorage. This pattern continues, resulting in four segments for a three-tower suspension bridge and five segments for a four-tower suspension bridge. Considering that four-tower and higher suspension bridges are not currently in practical use, this application is for two-tower and three-tower suspension bridges. Theoretically, this application could also be applied if four-tower and higher suspension bridges could be constructed.

[0009] Furthermore, each of the aforementioned traction heads includes: A rope extending longitudinally; Rope clamps for attaching the rope to the load-bearing cable; The rope end located at one end of the rope body is used to connect to the corresponding traction cable.

[0010] Specifically, another technical concept of this application is that by using a traction head composed of a rope body, rope clamp and rope end temporarily attached to the load-bearing cable, the load-bearing cable can be switched between adjacent traction cables when attached to the load-bearing cable, and can be disassembled and reused after the load-bearing cable has completed traction, thereby further reducing construction costs.

[0011] Furthermore, the rope clamp includes any one of a strap, a fastening screw, or a steel sleeve.

[0012] In some possible embodiments, the ropes of each traction head do not overlap; No. The length of the rope of the traction head is greater than the intersection distance between adjacent traction cables.

[0013] In some possible embodiments, the rope clamps are provided in multiple sets and are evenly distributed along the longitudinal direction of the rope.

[0014] In some possible embodiments, the rope end or the anchor head is connected to the traction rope via a triangular connector.

[0015] Specifically, another technical concept of this application is to use a triangular connector to establish a three-way force system, thereby achieving vector balance through the forces at the three points of the triangular connector. This allows the force applied by the load-bearing cable to the traction rope to be vector-decomposed and resolved through the two hypotenuses of the triangle, thus optimizing its mechanical transmission performance with the traction rope and reducing the traction risk during the traction process of the load-bearing cable.

[0016] Furthermore, the rope end or the anchor head is connected to the right-angle point of the triangular connector.

[0017] In some possible embodiments, the triangular connector includes a rod and flexible steel wire ropes connected to both ends of the rod.

[0018] Specifically, another technical concept of this application lies in using a flexible steel wire rope to dynamically adjust the stress state of the triangular connector. Compared with a fixed triangular connector, the flexible steel wire rope can adjust the position and angle of the load-bearing cable applied to the triangular connector, thereby dynamically adjusting the stress state of the triangular connector and realizing dynamic adjustment of the traction force.

[0019] In some possible embodiments, the rope end or the anchor head is connected to the triangular connector via a shackle. This application reduces the difficulty of connecting the traction rope, anchor head, and traction head through the connection hole and shackle, making operation and construction easier.

[0020] The beneficial technical effects of the technical solutions provided in this application include: The device for segmented traction conversion of the load-bearing cable provided in this application mainly utilizes The traction head and anchor head are used to switch the load-bearing cable between adjacent traction cables. Without changing the structural composition of the segmented traction system, this method requires less personnel involvement and less temporary construction investment. Workers only need to... After the group of traction heads completes traction via the corresponding section of traction cable, it will move the first... By connecting the traction head to the next traction cable segment, the switching of the load-bearing cable between adjacent traction systems can be achieved. This reduces manual intervention, minimizes modifications to the traction system, significantly mitigates the risks of working at heights, and ensures the reliability of the traction system. Furthermore, this application only requires connecting a detachable traction head to the load-bearing cable to achieve traction switching within a segmented traction system, without altering the traction mechanism of the traction system. This results in higher traction reliability and minimal construction costs. Therefore, this application offers advantages such as simple operation, reliability, and low cost.

[0023] Those skilled in the art will understand that, unless specifically stated otherwise, the terms "described" and "the" as used herein may also include plural forms. It should be further understood that the term "comprising" as used in the specification of this application means the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by this art.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0025] Please refer to Figure 1 This is a schematic diagram of a device for segmented traction conversion of a load-bearing cable according to an embodiment of this application.

[0026] Specifically, the method for segmented traction conversion of the load-bearing cable 1 provided in this application mainly relies on the anchor head 4 set at the traction end 101 and The traction head is used to achieve this. The load-bearing cable 1 refers to the cable that needs to be pulled in the air by the traction system, including the catwalk cable or the main cable strand. If other cables that need to be pulled in sections during bridge construction, the traction conversion device for the load-bearing cable 1 provided in this application can also be used.

[0027] In this application, the traction end 101 of the load-bearing cable 1 refers to the end of the load-bearing cable 1 used for traction by the traction system, and its end is configured as an anchor head 4. The anchor head 4 can be understood by referring to the anchor head 4 of the load-bearing cable 1 in a continuous traction system. That is, the traction end 101 of the load-bearing cable 1 in this application is sequentially provided with Group 4 of traction heads and anchor heads, and each group of traction heads is defined as the 4th group. Group traction head, first Group traction head to the first Group traction head, number The traction head is closest to the anchor head 4; , Take the integer part.

[0028] It is worth explaining that the first Group traction head and the first Group traction heads are used to distinguish adjacent traction heads, for example: at the start, The value is 1, the first Group traction head and the first The first conversion combination consisting of the traction heads is {first traction head 2, second traction head 3}. After completing the first traction head conversion, The value is 2, the first The first group of traction heads, together with the next adjacent traction head, forms a second group of traction heads, namely {second group traction head 3, third group traction head (not shown in the figure)}, and so on, until the group closest to anchor head 4. In the group traction head For example, in the case of the twin-tower suspension bridge No. 7, That is, the traction end 101 includes a first set of traction heads 2, a second set of traction heads 3, and an anchor head 4; in a three-tower suspension bridge, 3, that is, the traction end 101 includes the first traction head 2, the second traction head 3, the third traction head and the anchor head 4, and so on. Theoretically, It can be infinitely large, but in reality... The value of is limited by the number of towers in a suspension bridge in reality. Currently, only three-tower suspension bridges exist in reality. Suspension bridges with four or more towers have not been put into practice. Therefore, this application is currently only applied to two-tower suspension bridges and three-tower suspension bridges. If suspension bridges with four or more towers can be manufactured in reality, the application can theoretically also be applied to suspension bridges with four or more towers.

[0029] Optionally, each traction head includes a longitudinally extending rope body 201, a rope clamp 202 for attaching the rope body 201 to the load-bearing cable 1, and a rope end 203 disposed at one end of the rope body 201. The rope end 203 is used to connect to the corresponding traction cable, that is, the rope end 203 is a knot formed by closing one end of the rope body 201 for attaching to the traction cable, while the rope body 201 is fixed to the traction end 101 by the rope clamp 202.

[0030] Optionally, the rope clamp 202 includes any one of a strap, a fastening clamp, or a fastening sleeve. It is worth explaining that the rope clamp 202 is a component used to fix two cables and prevent relative slippage between them. It can be used in various ways such as binding, wrapping, and locking. This should be interpreted broadly; any component used to fix the rope 201 and the load-bearing cable 1 and prevent relative slippage during construction can achieve the function of the rope clamp 202 in this application.

[0031] Optionally, the ropes 201 of each traction head do not overlap, so as to achieve individual traction of the traction end 101 by each rope 201, and facilitate the removal of each traction head after traction is completed; The length of the rope 201 of the group traction head is greater than the intersection distance between adjacent traction cables, because the first The rope head 203 of the group traction head is used to connect to the first The first section of the traction cable, and the second section... The rope head 203 of the group traction head and the first The distance between the rope ends 203 of the group traction head is basically the first The length of the rope 201 of the group traction head, due to the first The rope head 203 of the group traction head is connected to the first The traction cable segment, only when the first The length of the rope 201 of the group traction head is greater than that of the first group. From the start of the traction cable to the... The distance from the termination point of the traction cable segment is required to achieve the first... The rope head 203 of the group traction head and the first The connection of the traction cable segments to enhance the first The operability of segmented conversion of the traction head. That is, at the node, the length of the rope 201 of the next traction head is greater than the handover distance between the next traction cable and the previous traction cable, which is used to connect the rope head 203 of the next traction head to the next traction cable.

[0032] Optionally, multiple sets of rope clamps 202 are provided and evenly distributed along the longitudinal direction of the rope body 201 to provide a reliable connection between the rope body 201 and the load-bearing cable 1 for traction of the load-bearing cable 1.

[0033] Furthermore, this application is based on Figure 2 The working principle of this application will be explained using the double-tower suspension bridge 7 as an example. Please refer to [reference needed]. Figure 2 This is a schematic diagram of the segmented traction conversion of the load-bearing cable 1 in the 7th section of the double-tower suspension bridge.

[0034] Specifically, in combination Figure 1 Regarding the traction end 101, The description of the traction head and anchor head 4, in the scenario of a double-tower suspension bridge 7, shows that the traction end 101 of the load-bearing cable 1 includes the sequentially arranged... Group traction head, first The traction head and anchor head 5, namely the first traction head 2, the second traction head 3, and the anchor head 4, are defined in this application for ease of explanation of the working principle. Section traction cable, the first Section traction cable and the first The traction cable segment, because the traction system is divided into three segments by the first anchorage 71, the first tower 72, the second tower 73, and the second anchorage 74 of the double-tower suspension bridge 7, is used to address scenarios where the construction environment is limited or the construction cost is limited. Specifically, the segment between the first anchorage 71 and the first tower 72 includes: a first traction cable segment 8, a second traction cable segment 9, and a third traction cable segment 10. Accordingly, this application also defines the... The node, the first The node and the first The nodes are: the first node 11 at the top of the first tower 72, the second node 12 at the top of the second tower 73, and the third node 13 at the top of the second anchorage 74. Therefore, in the double-tower suspension bridge 7, the working principle of the segmented traction conversion device for the load-bearing cable 1 provided in this application is as follows: The first set of traction heads 2 is connected to the first section of traction cable 8 between the first anchorage 71 and the first tower 72. The first set of traction heads 2 is then pulled to the first node 11, i.e., to the top of the first tower 72, via the first section of traction cable 8. At the first tower 72, the first section of traction cable 8 is switched to the second section of traction cable 9. In existing technologies, workers typically remove the anchor head 4 of the load-bearing cable 1 from the first section of traction cable 8 and then pull it to the second section of traction cable 9 for fixation. Since workers need to pull the traction end 101 of the load-bearing cable 1 from the top of the first tower 72, and the top of the first tower 72 is at a high altitude with the load-bearing cable 1 having significant weight, there are risks associated with working at height, especially under the influence of crosswinds or the downward force of the load-bearing cable 1. While existing technologies also include installing a switching component at the top of the first tower 72, this requires additional switching parts to achieve the switching of the load-bearing cable 1 between different traction cables. This increases the complexity of the traction system and reduces its reliability. In this application, the aforementioned operations in the prior art are unnecessary. It is sufficient to connect the second set of traction heads 3 to the second section of traction cable 9. Since the second set of traction heads 3 is closer to the anchor head 4 than the first set of traction heads 2, when the first set of traction heads 2 is pulled to the first node 11, the second set of traction heads 3 has displacement margin toward the second section of traction cable 9 and can be easily connected to it. Because the load-bearing cable 1 is restricted by the first set of traction heads 2 during the connection of the second set of traction heads 3 to the second section of traction cable 9, the risk of high-altitude operations for workers is avoided. After the second set of traction heads 3 is connected to the second section of traction cable 9 between the first tower 72 and the second tower 73, the first set of traction heads 2 is released from the first section of traction cable 8, allowing the load-bearing cable 1 to be pulled via the second section of traction cable 9 through the second set of traction heads 3 until the second set of traction heads 3 is pulled to the second node 12, i.e., the top of the second tower 73. It is understandable that the length of the rope 201 of the second traction head 3 is greater than the handover distance at the first node, that is, greater than the handover distance between the first traction cable 8 and the second traction cable 9. This allows the workers to easily connect the rope end 203 of the second traction head 3 to the second traction cable 9, and so on. At this time, at the second node 12, that is, at the top of the second tower 73, the operation of connecting the next traction head and disconnecting the previous traction head is performed. Since this application is a double-tower suspension bridge, the second traction head 3 is the first At this point, the anchor head 4 is connected to the third traction cable 10 at the second node 12, which is the traction cable between the second tower 73 and the second anchor 74. The connection between the second group of traction heads 3 and the second traction cable 9 is released. Thus, the load-bearing cable 1 can be pulled to the third node 13, which is the second anchor 74, through the third traction cable 10 and the anchor head 4. This realizes the segmented traction of the load-bearing cable 1 from the first anchor 71 to the second anchor 74. Because the above-mentioned traction process only requires connecting the first set of traction heads 2 to the first traction cable 8 at the first anchor 71, connecting the second set of traction heads 3 to the second traction cable 9 at the first node 11 (top of the first tower 72) and disconnecting the first set of traction heads 2 from the first traction cable 8, and connecting the anchor head 4 to the third traction cable 10 at the second node (top of the second tower 73) and disconnecting the second set of traction heads 3 from the second traction cable 9, the segmented traction conversion of the load-bearing cable 1 in the segmented traction system can be realized. The whole process is safe and reliable with low manual intervention, which can effectively reduce the operational risks of high-altitude operations, while reducing construction costs and investment.

[0035] It is worth explaining that, for a three-tower suspension bridge, one can refer to... Figure 2 The double-tower suspension bridge 7 shown is understood in the following way: the difference is that the three-tower suspension bridge includes a third tower (not shown in the figure). Accordingly, at the second node 12, i.e., the second tower 73, the third set of traction heads is connected to the third section of traction cable 10 between the second tower 73 and the third tower. Then, the connection between the first set of traction heads 2 and the first section of traction cable 8 is released. The load-bearing cable 1 can then be pulled to the third node 13, i.e., the top of the third tower, through the third section of traction cable 10 and the third set of traction heads. Since the third set of traction heads is the... The third traction head, at the third node 13, i.e., at the top of the third tower, connects the anchor head 4 to the fourth traction cable segment between the third tower and the second anchorage 74. The connection between the third traction head and the third traction cable segment 10 is then released. The load-bearing cable 1 can then be pulled to the fourth node, i.e., the second anchorage 74, via the fourth traction cable segment and the anchor head 4. Therefore, based on the segmented traction conversion of the load-bearing cable 1 in the scenarios of a double-tower suspension bridge 7 and a three-tower suspension bridge, the provisions of this application can be understood. Group traction head, No. Group traction head, No. Working principle of the traction head and anchor head 4.

[0036] Alternatively, please refer to Figure 3 for Figure 2 Enlarged diagram of direction A in the diagram. Figure 4 for Figure 2 Enlarged diagram of point B in the middle.

[0037] Specifically, both ends of the first traction cable 8, the second traction cable 9, and the third traction cable 10 are pulled by the first winch 5 and the second winch 6. The first winch 5 for the first traction cable 8 is located at the first anchorage 71, and the second winch 6 (see reference) Figure 3 The winch on the left is located on the temporary first tower platform erected on the top of the first tower 72 (not shown in the figure); the first winch 5 of the second traction cable 9 (see reference) Figure 3 The winch on the right is also located on the first tower platform and is opposite to the second winch 6 of the first section of the load-bearing cable 1. The second winch 6 (see reference) Figure 4 The winch on the left is located on the temporary second tower platform erected on top of the second tower 73 (not shown in the figure); the first winch 5 of the third traction cable 10 (please refer to...) Figure 4 The winch on the right is located on the second tower platform and opposite the second winch 6 of the second section of the load-bearing cable 1. The second winch 6 is located on the second anchorage 74. Therefore, the traction principle of the traction cable in this application is that by unwinding the first winch 5 and simultaneously winding it up through the second winch 6, the traction cable between the first winch 5 and the second winch 6 is wound towards the second winch 6, thus achieving traction on the load-bearing cable 1 connected to the traction cable. It is worth explaining that a winch refers to a small, lightweight lifting device that uses a drum to wind steel wire rope or chain to lift or pull heavy objects.

[0038] Optionally, this application can also achieve reverse traction of the traction cable by unwinding the cable through the second winch 6 and simultaneously winding it up through the first winch 5, thereby realizing the reciprocating erection of the load-bearing cable 1 between suspension bridges.

[0039] Further, please refer to Figure 5 The first embodiment provided in this application Group traction head and the first A schematic diagram of the connection of the traction cable segment.

[0040] Specifically, this application uses a triangular connector 14 to connect the load-bearing cable 1 and the traction cable. (The last sentence appears to be incomplete and possibly refers to a different application.) Group traction head and the first Taking the connection of the traction cable as an example, the traction cable is split on both sides of the triangular connector 14, with the first section 301 wound around the first winch 5 and the second section 302 wound around the second winch 6. These sections are connected to the first and second points of the triangular connector 14, respectively, while the third point of the triangular connector 14 is used to connect the rope end 203. Due to the triangular structure of the triangular connector 14, the force applied by the load-bearing cable 1 to the traction cable can be optimized. Compared to the prior art where the load-bearing cable 1 is directly connected to the traction cable via the rope end 203, the reaction force applied by the load-bearing cable 1 to the traction cable is decomposed into forces along the two sides of the triangular connector 14 and then further decomposed through the first section 301 and the second section 302. This allows the reaction force to be borne by the first section 301 and the second section 302, avoiding the stress concentration problem of direct connection in the prior art. The force distribution is more reasonable, and the risk of traction loss of control is lower.

[0041] Optionally, the triangular connector 14 is configured as a right triangle, with the third point configured as a right-angle point, for further optimization of the force based on the Pythagorean theorem.

[0042] Optionally, the triangular connector 14 includes a plate 141, connecting holes disposed on the edge of the plate 141 corresponding to the first point, the second point, and the third point, and a shackle (not shown in the figure) connected to the connecting holes. This application provides a shackle on the triangular connector 14, allowing for convenient operation whether disassembling the rope end 203 of the upper traction cable or attaching the rope end 203 of the lower traction cable.

[0043] Optionally, in the In the section of the traction cable, the third point of the triangular connector 14 is used to connect the anchor head 4.

[0044] In some embodiments, please refer to Figure 6 The first embodiment provided in this application Group traction head and the first A schematic diagram of the connection of the traction cable segment.

[0045] Specifically, the triangular connector 14 and Figure 5 The difference is that the triangular connector includes a rod 142 and a flexible steel wire rope 143. The flexible steel wire rope 143 is connected to both ends of the rod 142, so that the load-bearing cable is connected to the middle of the flexible steel wire rope 143 in a non-slip connection through a shackle. This makes the position of the shackle relative to the flexible steel wire rope 143 adjustable, and thus the triangular shape formed by the rod 142 and the flexible steel wire rope 143 adjustable. That is, the included angle of the shackle pulling the flexible steel wire rope 143 is adjustable. In other words, the force structure of the triangular connector 14 can be optimized by itself based on the force, which improves the reliability of the load-bearing cable traction.
