A main cable turning bracket

Abstract

This invention relates to a main cable steering support, comprising: a support; a vertical limiting structure and a horizontal limiting structure, both fixed to the support; the horizontal limiting structure is configured to offset the main cable by a first preset distance in the horizontal plane, and the vertical limiting structure is configured to offset the main cable by a second preset distance in the vertical direction. This invention constructs the steering support between the anchorage and the main tower. The main cable starts from the anchorage, passes through the horizontal limiting structure to change its horizontal offset, and then passes through the vertical limiting structure to change its height limitation. This allows the main cable to change its travel path between the anchorage and the main tower, avoiding large spatial and angular deviations between the anchorage and the main tower, which could lead to excessive bending at both ends of the main cable, significant frictional damage, affecting the safety of the cable crane, and compromising the construction quality of the suspension bridge's main cable.

Description

Technical Field

[0001] This invention relates to the field of support construction, and in particular to a main cable steering support. Background Technology

[0002] A suspension bridge, also known as a suspension bridge, is a structure whose main load-bearing component is a cable (or steel chain) suspended from towers and anchored to both banks (or both ends of the bridge). The geometry of the cable is determined by force equilibrium conditions and generally approximates a parabola. Numerous suspenders hang from the cable, supporting the bridge deck. Stiffening beams are often installed between the bridge deck and the suspenders, forming a combined system with the cable to reduce deflection caused by loads.

[0003] In related technologies, due to spatial and angular deviations between the main cable at the anchorage and the main cable at the main tower, the main cable of the cable crane conflicts with the spatial position at the anchorage, causing certain frictional damage, affecting the safety of the cable crane, and failing to guarantee the construction quality of the main cable of the suspension bridge. Summary of the Invention

[0004] This invention provides a main cable steering bracket to solve the problem in related technologies where the spatial position of the main cable of a cable crane conflicts with that of the anchorage, causing frictional damage, affecting the safety of the cable crane, and failing to guarantee the construction quality of the main cable of the suspension bridge.

[0005] This invention provides a main cable steering bracket, which includes:

[0006] support;

[0007] A vertical limiting structure and a horizontal limiting structure, both of which are fixed to the bracket;

[0008] The horizontal limiting structure is configured to offset the main cable by a first preset distance in the horizontal plane, and the vertical limiting structure is configured to offset the main cable by a second preset distance in the vertical direction.

[0009] In some embodiments, there are two horizontal limiting structures, and the vertical limiting structure is fixed between the two horizontal limiting structures;

[0010] One of the horizontal limiting structures, the vertical limiting structure, and the other horizontal limiting structure are arranged according to the threading direction of the main cable.

[0011] In some embodiments, the vertical limiting structure includes:

[0012] Multiple anchor plates are spaced apart along the width direction of the bracket and are all fixed to the bracket;

[0013] Four first pins are arranged along the height direction of the bracket, the length direction of each first pin is consistent with the width direction of the bracket, and all four first pins pass through multiple anchor plates.

[0014] Along the height direction of the bracket, a first limiting space is formed between the first first pin and the second first pin, and the first limiting space is divided into multiple first limiting units by multiple anchor plates; a second limiting space is formed between the third first pin and the fourth first pin, and the second limiting space is divided into multiple second limiting units by multiple anchor plates.

[0015] In some embodiments, a first nylon sleeve is rotatably mounted on the outer wall of the first pin within the space formed by the spaced arrangement of the plurality of anchor plates.

[0016] In some embodiments, each of the horizontal limiting structures includes:

[0017] Multiple second pins are provided, the number of which corresponds one-to-one with the number of anchor plates and are fixed to the corresponding anchor plates. The length direction of each second pin is consistent with the length direction of the corresponding anchor plate.

[0018] A third limiting space is formed between any two adjacent second pins.

[0019] In some embodiments, each of the horizontal limiting structures further includes:

[0020] Three anchor boxes are spaced apart along the height direction of the support and are all fixed to multiple anchor plates;

[0021] Each of the second pins passes through and is fixed to the three anchor boxes in sequence, and each of the third limiting spaces is divided into two third limiting units by the three anchor boxes.

[0022] In some embodiments, within the space formed by the three anchor boxes spaced apart, the outer wall of each second pin is fitted with a second nylon sleeve.

[0023] In some embodiments, the support includes:

[0024] Two vertical beams, with a crossbeam fixed between the tops of the two vertical beams;

[0025] Two adjustable structures are provided, each corresponding to one of the two vertical beams and fixed to the corresponding vertical beams.

[0026] The two adjustable structures adjust the horizontal height of the crossbeam.

[0027] In some embodiments, each of the vertical beams includes: a first column and a second column;

[0028] Each of the aforementioned adjustment structures includes: at least one fixing bolt and multiple pads;

[0029] Multiple pads are stacked between the first column and the second column, and the fixing bolts pass through the multiple pads to fix the multiple pads between the first column and the second column.

[0030] In some embodiments, at least one diagonal support beam is fixed to each of the vertical beams.

[0031] The beneficial effects of the technical solution provided by this invention include: constructing the steering support between the anchorage and the main tower; the main cable starts from the anchorage, passes through the horizontal limiting structure to change the offset of the main cable in the horizontal direction, and then passes through the vertical limiting structure to change the limiting of the main cable in the height direction, thereby realizing the change of the main cable's travel path between the anchorage and the main tower. This avoids large deviations in spatial position and angle between the main cable and the main tower, which would lead to excessive bending at both ends of the main cable, resulting in significant frictional damage, affecting the safety of the cable crane, and failing to guarantee the construction quality of the suspension bridge's main cable.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides a main cable steering bracket to solve the problem in related technologies where the spatial position of the main cable of a cable crane conflicts with that of the anchorage, causing frictional damage, affecting the safety of the cable crane, and failing to guarantee the construction quality of the main cable of the suspension bridge.

[0045] like Figure 1-4 As shown, an embodiment of the present invention provides a main cable steering bracket, which may include: a bracket 1; a vertical limiting structure 2 and a horizontal limiting structure 3, both of which are fixed to the bracket 1; the horizontal limiting structure 3 is configured to offset the main cable 4 by a first preset distance in the horizontal plane, and the vertical limiting structure 2 is configured to offset the main cable 4 by a second preset distance in the vertical direction. Wherein, as... Figure 1 As shown, its left-right direction represents the width of support 1, its up-down direction represents the height of support 1, and its front-back direction represents the length of the suspension bridge. That is, the anchorage is behind support 1, and the main tower is in front of support 1. Specifically, support 1 is fixed between the anchorage and the main tower, as shown... Figure 3 As shown, the horizontal limiting structure 3 can be fixed to the rear side of the vertical limiting structure 2, as follows. Figure 4As shown, the multiple main cables 4 at the anchorage first pass through the horizontal limiting structure 3 on the support 1, thus shifting the main cables 4 to the left by a first preset distance; as shown... Figure 4 and Figure 5 As shown, the main cable 4 then passes through the vertical limiting structure 2, offsetting and limiting the main cable 4 upwards. During the process from the horizontal limiting structure 3 to the vertical limiting structure 2, the height of the main cable 4 changes by a second preset distance in the vertical direction. When the positional offset error between the anchor and the main tower is too large, it will cause the bending angles at both ends of the main cable 4 to be too large, which will easily cause contact with the anchor and the main tower, resulting in frictional wear and affecting the service life of the main cable 4. The main cable turning bracket is connected between the anchor and the main tower, which can offset the path of the main cable 4, adjust the position of the main cable 4, and prevent the problem of excessive bending at both ends of the main cable 4.

[0046] Specifically, the support frame 1 is constructed between the anchorage and the main tower. The bottom of the support frame 1 is embedded in the concrete 6 through pre-embedded parts 5, thus fixing the support frame 1 to the ground. The main cable 4 starts from the anchorage, passes through the horizontal limiting structure 3 to change the horizontal offset of the main cable 4, and then passes through the vertical limiting structure 2 to change the height limit of the main cable 4. This allows the main cable 4 to change its travel path between the anchorage and the main tower, avoiding large deviations in the spatial position and angle of the main cable 4 between the anchorage and the main tower. This would prevent excessive bending at both ends of the main cable 4, resulting in significant frictional damage, affecting the safety of the cable crane, and compromising the construction quality of the main cable of the suspension bridge. When tunnel anchors are used for construction at the anchorage, the main cable of the cable crane can be anchored to the front anchor surface of the tunnel anchor plug through this bracket 1, avoiding the need for a large amount of manual excavation of piles and pouring of large volumes of concrete. At the same time, it prevents friction damage caused by spatial conflicts between the main cable of the cable crane and the main cable and the side wall of the tunnel anchor, which would affect the safety of the cable crane.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, there are two horizontal limiting structures 3, and a vertical limiting structure 2 is fixed between the two horizontal limiting structures 3; one horizontal limiting structure 3, the vertical limiting structure 2, and the other horizontal limiting structure 3 are arranged according to the threading direction of the main cable 4. Figure 5 for Figure 4 In the right-side view, after the main cable 4 passes through the middle vertical limiting structure 2, it passes through a horizontal limiting structure 3 again. This provides a second limiting for the main cable 4 in the horizontal plane, extending the limiting length of the main cable 4 and ultimately pulling the main cable 4 to the main tower. This avoids excessive bending of the main cable 4 between the vertical limiting structure 2 and the main tower, which could lead to wear and damage at the vertical limiting structure 2.

[0048] Furthermore, the overall height of the horizontal limiting structure 3 on the right side can be higher than the overall height of the horizontal limiting structure 3 on the left side, ensuring the overall climbing trend of the main cable 4.

[0049] Among them, such as Figure 1 and Figure 3 As shown, two horizontal limiting structures 3 and one vertical limiting structure 2 form a set of limiting components. In the width direction of the support 1, two sets of limiting components are installed on the support 1. Each set of limiting components limits and offsets multiple main cables 4 on one side of the main tower of the bridge.

[0050] In some embodiments, such as Figure 2 and Figure 6 As shown, the vertical limiting structure 2 may include: multiple anchor plates 21, spaced apart along the width direction of the support 1 and all fixed to the support 1; four first pins 22, arranged along the height direction of the support 1, with the length direction of each first pin 22 consistent with the width direction of the support 1, and all four first pins 22 penetrating through the multiple anchor plates 21; along the height direction of the support 1, from top to bottom, a first limiting space is formed between the first first pin 22 and the second first pin 22, and the first limiting space is divided into multiple first limiting units by the multiple anchor plates 21; a second limiting space is formed between the third first pin 22 and the fourth first pin 22, and the second limiting space is divided into multiple second limiting units by the multiple anchor plates 21. Each first limiting unit corresponds to one main cable 4, and each second limiting unit also corresponds to one main cable 4, thereby sequentially limiting and offsetting the multiple main cables 4 of the double-layer structure in the height direction, enabling the main cables 4 to be arranged in multiple layers, saving space.

[0051] In some embodiments, such as Figure 6 As shown, within the space formed by the spaced arrangement of multiple anchor plates 21, a first nylon sleeve 23 is rotatably mounted on the outer wall of the first pin 22. This facilitates the main cable 4 to move within two of the first nylon sleeves 23, reduces its coefficient of friction, and also ensures a good limiting effect on the main cable 4.

[0052] In some embodiments, such as Figure 6 and Figure 7 As shown, each horizontal limiting structure 3 may include: multiple second pins 31, the number of which corresponds one-to-one with the number of anchor plates 21, and fixed to the corresponding anchor plates 21. The length direction of each second pin 31 is consistent with the length direction of the corresponding anchor plate 21; a third limiting space is formed between any two adjacent second pins 31. Each third limiting space is used for the passage of the two main cables 4, which are then subjected to layered limiting offset by the first and second limiting units in the vertical direction, changing the height offset of the two main cables 4.

[0053] In some embodiments, such as Figure 5 and Figure 7 As shown, each horizontal limiting structure 3 may further include: three anchor boxes 32, spaced apart along the height direction of the support 1, each anchor box 32 being fixed to multiple anchor plates 21 by a bolt plate 34; each second pin 31 passing through and being fixed to the three anchor boxes 32 in sequence, and each third limiting space being divided into two third limiting units by the three anchor boxes 32. The third limiting space is also divided into two third limiting units by the three anchor boxes 32, and the two third limiting units located in the same vertical direction similarly limit the double-layer main cable 4, preventing the two main cables 4 of the double-layer structure from becoming entangled and affecting the erection of the main cable 4. Specifically, the horizontal limiting structure 3 and the vertical limiting structure 2 have clearly defined forces, are easy to install and dismantle, have strong assembly capabilities, good versatility, and facilitate construction.

[0054] In some embodiments, such as Figure 7 As shown, within the space formed by the three anchor boxes 32 spaced apart, each second pin 31 has a second nylon sleeve 33 fitted onto its outer wall. The second nylon sleeve 33 ensures the service life of the main cable 4, reduces its wear, and facilitates the restraint and passage of the main cable 4.

[0055] In some embodiments, such as Figure 1 As shown, the support 1 may include: two vertical beams 11, with a crossbeam 12 fixed between the top ends of the two vertical beams 11. Multiple stiffening plates 121 are fixedly installed on the crossbeam 12 along its length to improve its structural strength; two adjusting structures 13, each corresponding to one of the two vertical beams 11 and fixed to the corresponding vertical beam 11; the two adjusting structures 13 adjust the horizontal height of the crossbeam 12. The adjusting structures 13 can adjust the horizontal height of the crossbeam 12, thereby changing the overall height of the multiple main cables 4 to adjust according to actual conditions.

[0056] In some embodiments, such as Figure 1 and Figure 9As shown, each vertical beam 11 may include: a first column 111 and a second column 112; each adjusting structure 13 may include: four fixing bolts 131 and multiple pads 132; the multiple pads 132 are stacked between the first column 111 and the second column 112, and the four fixing bolts 131 all pass through the multiple pads 132 to fix the multiple pads 132 between the first column 111 and the second column 112. When it is necessary to adjust the height of the crossbeam 12, the first column 111 and the second column 112 are opened by jacking, and the horizontal height of the crossbeam 12 is increased by increasing the number of pads 132, or the horizontal height of the crossbeam 12 is decreased by decreasing the number of pads 132, thereby realizing the offset limiting work in the height direction of the main cable 4.

[0057] In some embodiments, such as Figure 1 As shown, each vertical beam 11 is fixed with at least one diagonal support beam 14. Among them, as... Figure 3 As shown, a diagonal support beam 14 is similarly fixedly installed in front of the vertical beam 11 to ensure the installation of the bracket 1. The bracket 1 adopts a prefabricated structure, with the horizontal beam 12, the first column 111, and the second column 112 connected by bolts. It can be used in other projects, saving a lot of steel.
