Description

Technical Field

[0001] The utility model relates to the field of offshore anchor cable installation, in particular to an anchor cable passing and steering bracket. Background Art

[0002] With the advancement of engineering technology, some large-span bridges have developed rapidly. In the process of bridge construction, anchor cables are usually used in the construction of large floating structures such as large steel caissons. This is mainly to ensure the fixation and stability of large floating structures such as steel caissons underwater. Anchor cables can provide additional support and fixing force by connecting the caisson and anchor points on the foundation or the bottom of the water to prevent the caisson from moving or tilting under the action of water flow, waves or other external forces. This can ensure the stability of the caisson's position underwater and provide a reliable support foundation for the bridge structure.

[0003] The existing caisson is usually towed by multiple anchor cables. After the anchor cables are installed, due to the influence of environmental factors such as waves, the position of the caisson will continue to stably deviate towards a certain anchor cable, which will cause the other anchor cables of the caisson to fail to be installed smoothly, making it impossible for the caisson to enter the groove accurately. Figure 6 As shown, after underwater exploration by divers, it was found that the gravity anchor end of a side cable was entangled with the gravity anchor, which caused the cable force of the anchor cable to be too large.

[0031] In order to further understand the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Combination Figure 1-Figure 5 An embodiment of the utility model provides an anchor cable passing cable steering bracket, comprising: a steering seat 35 for being arranged on the top of a large floating structure; and a cable withdrawal ramp 4 arranged at the front end of the steering seat 35. The large floating structure can be a structure such as a steel caisson 1.

[0033] The steering seat 35 includes two inner steering plates 35a and 35b arranged on the inner side of the cable passing bracket 2, and a loudspeaker cable passing passage 36 with a notch facing outward is formed between the two inner steering plates 35a and 35b. The front end of the cable withdrawal ramp 4 gradually rises toward the rear end, and the rear end of the cable withdrawal ramp 4 is not lower than the steering seat 35. The front end of the loudspeaker cable passing passage 36 (roughly the position indicated by the reference numeral 35) is narrow, and the closed cable joint 6 of the anchor cable 7 cannot enter the loudspeaker cable passing passage 36. Then, by setting the cable withdrawal ramp 4, the closed cable joint 6 is lifted to the top of the steering seat 35 when withdrawing the cable, so as to realize the cable withdrawal.

[0034] In this embodiment, the horn cable passage 36 formed by two inner steering plates 35a, 35b can guide and limit the anchor cable of the large floating structure, limit the anchor cable passage, and the anchor cable passes through the horn cable passage to enter the top of the large floating structure. In the process of changing the cable force of the abnormal anchor cable 7 and adjusting the posture and angle of the large floating structure, the inclination angle of the cable withdrawal ramp 4 can lift the abnormal anchor cable to pass above the steering seat, so that the abnormal anchor cable 7 enters the horn cable passage 36 for cable withdrawal, and then will not be close to one of the inner steering plates 35a, 35b, eliminating the friction between the anchor cable 7 and the inner steering plates 35a, 35b, and protecting the steering seat. In addition, during the cable withdrawal process, the anchor cable is gradually lifted by the cable withdrawal ramp 4 until the closed cable joint of the anchor cable is lifted to pass over the steering seat, providing convenience for cable withdrawal.

[0035] Combination Figure 1-Figure 5 The cable withdrawal ramp 4 is supported by a plurality of I-beams 3 below. The heights of the plurality of I-beams 3 gradually increase from the front to the back.

[0036] In this embodiment, the multiple I-beams 3 below the cable withdrawal ramp 4 use their own structural characteristics to support the cable withdrawal ramp 4 while also enabling the cable withdrawal ramp 4 to have a good bearing capacity, so that the cable withdrawal ramp 4 will not collapse when the cable force of the anchor cable 7 increases. At the same time, the heights of the multiple I-beams 3 increase from front to back, so that the cable withdrawal ramp 4 initially has a certain inclination angle, so that the cable withdrawal ramp 4 has a certain force range at the initial stage of the change of the cable force of the anchor cable. At the same time, the inclined cable withdrawal ramp 4 can gradually lift the anchor cable during the cable withdrawal process until the closed cable joint 6 of the anchor cable is lifted to pass over the steering seat 35, providing convenience for cable withdrawal.

[0037] Combination Figure 1-Figure 5 The cable withdrawal ramp 4 includes rectangular tubes 41 arranged in parallel on both sides of the I-beam 3. The rectangular tubes 41 are gradually raised from the front end to the rear end; a cable withdrawal groove 42 is formed between the two rectangular tubes 41, which is supported on the top of the I-beams 3 arranged at intervals. The top surface of the I-beam 3 forms the bottom surface of the cable withdrawal groove 42; a plurality of I-beams 3 are arranged at intervals. The I-beam 3 can be an i20 I-beam, and the rectangular tube can be a 125X10mm rectangular steel tube.

[0038] The rectangular tube 41 is used to prevent the anchor cable from being displaced by a lateral force on its axis. When the anchor cable moves out of the cable-retracting ramp 4, the rectangular tube 41 gradually rises from the front end to the rear end and can be in close contact with the surface of the cable-retracting ramp 4. The cable-retracting groove 42 formed by the two rectangular tubes 41 can provide good guidance for the anchor cable, so that the anchor cable can be smoothly reeled in without being obstructed by foreign objects during the cable-retracting process.

[0039] Combination Figure 5 The auxiliary deflection baffle 8 is fixedly mounted on the cable support 2 and is located above the steering seat 35. The outer sides of the inner steering plates 35a and 35b are supported on the top of the large floating structure (steel caisson) through an I-beam support 81, and the I-beam support 81 is used to fix the inner steering plates 35a and 35b and the cable support 2.

[0040] In this embodiment, the cable support 2 can provide certain support to the auxiliary deflection baffle 8 to prevent the anchor cable 7 from pushing the auxiliary deflection baffle 8 to cause displacement during the displacement process. The auxiliary deflection baffle 8 located above the steering seat 35 can guide and limit the anchor cable 7.

[0041] Combination Figure 5 The auxiliary deflection baffle 8 is located above one of the inner steering plates 35a / 35b, and its inner wall is flush with the inner wall of the inner steering plate 35a / 35b or protrudes above the speaker cable passage 36. Cable passing brackets 2 are provided on both sides of the steering seat 35. The auxiliary deflection baffle 8 is fixedly connected to the cable passing bracket;

[0042] In this embodiment, the cable support 2 can provide certain support to the auxiliary deflection baffle 8 to prevent the anchor cable 7 from pushing the auxiliary deflection baffle 8 to cause displacement during the displacement process. The auxiliary deflection baffle 8 located above the steering seat 35 can guide and limit the anchor cable 7.

[0043] Before unwinding, one or more half clamps are provided at the front end of the steering seat 35 to temporarily lock the entangled anchor cable, and the front end of the anchor cable is provided with a closed cable joint 6. The closed cable joint 6 is limited in front of the steering seat 35 by the half clamp to avoid automatic unwinding after the closed cable joint 6 is connected to the pin 5 of the front traction device.

[0044] The purpose of temporarily locking the entangled anchor cable by the half clamp at the front end of the steering seat 35 is to prevent the anchor cable 7 from automatically falling off during the process of unwinding after contacting the entanglement. Then, the half clamp that temporarily locks the anchor cable is removed, and the anchor cable 7 is gradually loosened. When the abnormal anchor cable 7 slowly falls to the steering seat 35 under the action of its own weight, the joint is gradually lifted by the pre-set unwinding ramp 4 and the falling direction is limited by the pre-set auxiliary deflection baffle 8, so that the closed cable joint 6 can pass over the notch of the steering seat 35. At the same time, the closed cable joint 6 is used to connect with the winch to reel in the unwinding anchor cable 7.

[0045] A cable roller (not shown) is also set up on the top of the lateral support structure (cable support 2) on both sides, so that the traction wire rope connected to the abnormal anchor cable 7 can pass over the cable roller for transportation.

[0046] In such Figure 3 In a feasible embodiment shown, the upper ends of the inner deflection plates 35a, 35b are further provided with rectangular tubes 41 and steel tube edges 42. The rectangular tubes 41 and steel tube edges 42 strengthen the structural strength of the upper end of the speaker cable passage 36 of the deflection seat 35, and can prevent the anchor cable 7 from moving out of the passage during the cable passing process.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
