Description

Technical Field

[0001] The invention relates to the field of cable hoisting, and in particular to a composite cable installation and clamping tool suitable for horizontal construction of a conductor frame. Background Art

[0002] In existing tensioned impressed current cathodic protection technology, corrosion detection and protection of offshore platforms are achieved through a composite cable (hereinafter referred to as the cable) that integrates a reference electrode and an auxiliary anode. The cable is usually tensioned and arranged inside the platform. For horizontally constructed jackets, the cable cannot be installed vertically and can only be installed horizontally according to the jacket's construction posture. After the jacket is launched and straightened, the cable is transformed into a vertical service state as the jacket's posture changes.

[0003] At present, cables are installed during the land construction phase of new deep-water marine platforms. The cables generally need to be arranged at high altitudes. Cranes and slings are usually used to move the cables to the corresponding positions. After the cables are fixed, it is necessary to manually climb to the position where the slings and cables are hoisted and manually release the slings from the cables. Generally, the cables are long and need to have more than a dozen or even dozens of hoisting points. Moreover, the hoisting points are basically all at high altitudes. The manual removal of the hoisting points is not only very slow, but also very difficult and dangerous. Summary of the Invention

[0004] In order to overcome the above problems, the present invention provides a composite cable installation and clamping tool suitable for horizontal construction of a jacket. The technical solution adopted by the present invention to solve the technical problem is as follows:

The movable frame slides along the sliding rope. A self-detaching hook is hinged at the bottom of the movable frame. The self-detaching hook includes a hook head and a sinking head. The hook head and the sinking head are connected by a rotating part. The weight of the sinking head is greater than the weight of the hook head. The movable frame is hinged to the rotating part. An automatic opening ring is hung on the hook head, and a cable is fixed on the automatic opening ring. When the tension of the sliding rope is released, the sinking head is driven by gravity to lift the hook head, so that the hook head is decoupled from the automatic opening ring. After the automatic opening ring is decoupled, it automatically opens under the action of gravity to detach from the cable.

[0006] Furthermore, the automatic opening ring includes a first half ring and a second half ring, the first half ring includes a first hinged end and a first hanging end, the second half ring includes a second hinged end and a second hanging end, the first hinged end and the second hinged end are hinged, the first hanging end and the second hanging end are both provided with hanging interfaces, the first hanging end and the second hanging end abut / move away from each other to close / open the automatic opening ring; when the automatic opening ring is closed, the hanging interfaces of the first hanging end and the second hanging end coincide, and the hook head passes through the hanging interfaces of the first hanging end and the second hanging end at the same time to hang the automatic opening ring and limit the opening of the automatic opening ring.

[0007] Furthermore, it also includes a sleeve, which is sleeved and fixed on the cable, and a sleeve groove is provided on the outer wall of the sleeve along the circumference, and the automatic open ring is sleeved in the sleeve groove.

[0008] Furthermore, a fastening screw perpendicular to the axis of the cable is provided on the sleeve to abut against and fix the cable.

[0009] Furthermore, the sleeve includes a first half-cylinder and a second half-cylinder, which are detachably fixedly connected by a locking adjustment piece to form a sleeve. The locking adjustment piece adjusts the distance between the first half-cylinder and the second half-cylinder to adjust the size of the space inside the sleeve.

[0010] Furthermore, the locking adjustment part includes a locking nut and an adjusting screw. Locking holes are provided at both ends of the first half cylinder and the second half cylinder. The adjusting screw passes through the locking holes of the first half cylinder and the second half cylinder and is detachably fixedly connected to the locking nut; tighten / loosen the adjusting screw to adjust the size of the space inside the sleeve.

[0011] Furthermore, the movable frame includes a slide seat, a roller is provided in the slide seat, a sliding rope passes through the interior of the slide seat and is located directly below the roller, and the slide seat slides along the sliding rope through the roller.

[0012] Furthermore, a vertical downward connecting rod is provided at the bottom of the slide seat, and the bottom end of the connecting rod is hinged to the rotating part.

[0013] Furthermore, a lifting ring is fixed on the base to facilitate lifting the movable frame.

[0014] Furthermore, the hook head has a hook portion, and the angle of the hook portion is 55°-125°

[0015] The beneficial effects of the present invention are:

[0016] The tooling includes a mobile frame and a sling. The mobile frame slides along the sling. A self-detaching hook is hinged at the bottom of the mobile frame. The self-detaching hook includes a hook head and a sinker head. The hook head and sinker head are connected by a rotating part. The weight of the sinker head is greater than that of the hook head. The mobile frame is hinged to the rotating part. An automatic opening ring is hung on the hook head, and a cable is fixed on the automatic opening ring. When the tension of the sling is released, the sinker head is affected by gravity and drives the hook head to rise to disengage from the automatic opening ring. After the automatic opening ring is disengaged, it automatically opens under the action of gravity to detach from the cable. This tooling combines the mobile frame with the self-detaching hook. The self-detaching hook and the automatic opening ring work together and utilize gravity to automatically release the cable hoisting fixation by simply releasing the tension of the sling. There is no need for manual labor to release them one by one, which improves construction efficiency and ensures construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to better understand the purpose, structure and function of the present invention, the specific embodiment of the present invention "a composite cable installation and clamping tool suitable for horizontal construction of a conductor frame" is further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1 and Figure 2In this embodiment, the tooling includes a mobile frame 100 and a zip line 200. The mobile frame 100 slides along the zip line 200. A self-detaching hook 300 is hinged at the bottom of the mobile frame 100. The self-detaching hook 300 includes a hook head 301 and a sinking head 302. The hook head 301 and the sinking head 302 are connected by a rotating part 303. Preferably, the hook head 301, the sinking head 302 and the rotating part 303 are integrally formed. The weight of the sinking head 302 is greater than that of the hook head 301. The bottom of the mobile frame 100 is hinged to the rotating part 303. An automatic snap ring 400 is mounted on the hook head 301, and a cable 500 is fixedly sleeved on the automatic snap ring 400. After the mobile frame 100 slides along the zip line 200 to transport the cable 500 to the corresponding position and install it, the operator operates the pulley of the zip line 200 to release the tension of the zip line 200. At this time, the sinking head 302 sinks under the influence of gravity, thereby driving the hook head 301 to rise, so that the hook head 301 is unhooked from the automatic snap ring 400. After the automatic snap ring 400 is unhooked, it will automatically open and detach from the cable 500 under the action of gravity. The entire unhooking process does not require the operator to go to the height to work. It only needs to remotely release the tension of the zip line 200, so that all the cables 500 hoisting positions on this zip line 200 can be automatically unhooked, the hanging state is released, and the automatic snap ring 400 automatically falls off from the cable 500 and is automatically recovered. This tooling is not only efficient in unhooking and recovery, but also safer.

[0030] See further Figure 2 In this embodiment, the automatic open ring 400 includes a first half ring 401 and a second half ring 402. The first half ring 401 includes a first hinged end 4011 and a first hanging end 4012. The second half ring 402 includes a second hinged end 4021 and a second hanging end 4022. The first hinged end 4011 and the second hinged end 4021 are hinged. The first hanging end 4012 and the second hanging end 4022 are both provided with a hanging interface 403. The first hanging end 4012 and the second hanging end 4022 rotate along the hinged end to abut / move away from each other, thereby closing / opening the automatic open ring 400. The automatic open ring 400 closes When closed, the hanging interface 403 of the first hanging end 4012 and the second hanging end 4022 overlap, and the hook head 301 passes through the hanging interfaces 403 of the first hanging end 4012 and the second hanging end 4022 at the same time to hang the automatic open ring 400 and limit the automatic open ring 400 from opening under the action of gravity; only when the hook head 301 is unhooked from the hanging interface 403, the first half ring 401 and the second half ring 402 rotate relative to each other under the action of gravity, open the automatic open ring 400, and detach from the cable 500 and fall off, automatically releasing the restraint on the cable 500, thereby achieving the purpose of automatically recovering the open ring 400.

[0031] More specifically, in this embodiment, the tooling further includes a sleeve 501, which is sleeved and fixed on the cable 500. A sleeve groove 502 is circumferentially provided on the outer wall of the sleeve 501, and the automatic opening ring 400 is sleeved in the sleeve groove 502 to prevent the automatic opening ring 400 from slipping relative to the cable 500, thereby strengthening the sleeve fixation of the cable 500; and the sleeve 501 is located between the cable 500 and the automatic opening ring 400, which can protect the cable 500 and prevent the automatic opening ring 400 from damaging the cable 500 during the lifting and moving process.

[0032] See further Figure 3 In this embodiment, a fastening screw 503 perpendicular to the axis of the cable 500 is provided on the sleeve 501. The fastening screw 503 is tightened so that the top of the fastening screw 503 abuts and fixes the cable 500, preventing the sleeve 501 from sliding relative to the cable 500.

[0033] More specifically, in this embodiment, the sleeve 501 includes a first half-sleeve 504 and a second half-sleeve 505. The first half-sleeve 504 is detachably fixedly connected to the second half-sleeve 505 via a locking adjustment member to form the sleeve 501. An operator adjusts the distance between the first half-sleeve 504 and the second half-sleeve 505 via the locking adjustment member to adjust the size of the space within the sleeve 501. Preferably, the locking adjustment member includes a locking nut 506 and an adjusting screw 507. Locking holes 508 are provided at both ends of the first half-sleeve 504 and the second half-sleeve 505. The adjusting screw 507 passes through the locking holes 508 of the first half-sleeve 504 and the second half-sleeve 505 and is detachably fixedly connected to the locking nut 506. By tightening or loosening the adjusting screw 507, the operator can adjust the size of the space within the sleeve 501 to accommodate cables 500 of different diameters.

[0034] See further Figure 1 、 Figure 2 and Figure 4 In this embodiment, the movable frame 100 includes a slide 101, and a roller 102 is provided in the slide 101. The cable 200 passes through the left side of the slide 101 and out of the right side, passing directly under the roller 102. Preferably, two rollers 102 are arranged on the same straight line and distributed on the left and right sides. The slide 101 slides along the cable 200 through the rollers 102. The friction during sliding is reduced by rolling, so that the movable frame 100 slides on the cable 200 more stably and smoothly.

[0035] More specifically, in this embodiment, a vertically downward connecting rod 103 is fixed to the bottom of the slide 101, and the bottom end of the connecting rod 103 is hinged to the rotating part 303. Since the connecting rod 103 is rod-shaped, the self-detaching hook 300 can rotate at a larger angle; and the connecting rod 103 can be set to be detachable. By replacing the connecting rods 103 of different lengths, the tooling can be suitable for different application scenarios.

[0036] See further Figure 2 In this embodiment, the hook head 301 has a hook portion 3011, and the angle of the hook portion 3011 is 55°-125°. This can ensure that the hook head 301 will not be affected by natural wind and cause sudden unhooking when hanging the automatic opening ring 400, and can also ensure that it can be easily unhooked after the tension of the zip line 200 is released.

[0037] The following formula is used to calculate the swing angle of the hook portion 3011 and the wind force on the object: F = 1 / 2*ρAV^2*Cd, where ρ is the air density, which is 1.29 kg / m3, A is the projected area of ​​the object, which is 0.01 m2, V is the maximum wind speed, which is 20.7 m / s, and Cd is the air resistance coefficient of the object, which is 0.82. The wind force on the object is calculated to be 2.26 kg / m2. The weight of the hook portion 3011 is approximately 3 kg. Calculate ∠α: α=as in(a / c), a is 2.26, c is 3.756, the calculated result of ∠α is 36.99°<45°, and a safety factor of 1.2 times is reserved. The anti-slip angle of the hook part 3011 is designed to be 55°~125°.
