Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable hoisting, in particular to a composite cable installation and clamping tool suitable for horizontally built jacket. BACKGROUND

[0002] In the existing tension type impressed current cathodic protection technology, the corrosion state detection and protection of the offshore platform are realized by a composite cable (hereinafter referred to as cable) integrated with a reference electrode and an auxiliary anode. The cable is usually arranged in tension inside the platform. For the horizontally built jacket, the cable cannot be installed vertically, and can only be installed horizontally according to the posture of the jacket during the building stage. After the jacket is launched and righted, the posture of the jacket changes to the vertical service state.

[0003] At present, the cable needs to be arranged in the air during the land building stage of the newly built deepwater offshore platform. The cable is usually moved to the upper space of the corresponding position by using a crane and a sling. After the fixed positions of the cable are fixed, a worker needs to climb to the position of the sling and the cable hoisting to manually release the hoisting of the sling on the cable. Since the cable is usually long, ten or even dozens of hoisting points need to be set, and the hoisting points are basically in the air. The operation efficiency of the worker to release the hoisting points is not only very slow, but also has high operation difficulty and danger. SUMMARY

[0004] In order to overcome the above problems, the present application provides a composite cable installation and clamping tool suitable for horizontally built jacket. The technical scheme adopted by the present application to solve its technical problems is:

[0005] The composite cable installation and clamping tool suitable for horizontally built jacket comprises a moving frame and a sliding rope. The moving frame slides along the sliding rope. The moving frame is hingedly connected with a self-unhooking hook at the bottom. The self-unhooking hook comprises a hook head and a sinking head. The hook head and the sinking head are connected through a rotating part. The weight of the sinking head is greater than that of the hook head. The moving frame is hingedly connected with the rotating part. An automatic split ring is hung on the hook head. A cable is fixed on the automatic split ring through sleeving. When the tension of the sliding rope is released, the sinking head is driven to lift the hook head under the influence of gravity, so that the hook head is unhooked from the automatic split ring. After the automatic split ring is unhooked, it is automatically opened under the action of gravity to separate from the cable.

[0006] Further, the automatic split ring comprises a first half ring and a second half ring. The first half ring comprises a first hinged end and a first hanging end. The second half ring comprises a second hinged end and a second hanging end. The first hinged end and the second hinged end are hingedly connected. The first hanging end and the second hanging end are both provided with a hanging port. The first hanging end and the second hanging end abut / close to open / close the automatic split ring. When the automatic split ring is closed, the hanging ports of the first hanging end and the second hanging end coincide. The hook head passes through the hanging ports of the first hanging end and the second hanging end at the same time, so as to hang the automatic split ring and limit the opening of the automatic split ring.

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

[0008] Furthermore, the sleeve is equipped with fastening screws perpendicular to the axis of the cable to abut and secure the cable.

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

[0010] Furthermore, the locking adjustment component includes a locking nut and an adjusting screw. Both ends of the first and second half-cylinders are provided with locking holes. The adjusting screw passes through the locking holes of the first and second half-cylinders and is detachably fixed to the locking nut. Tightening / loosening the adjusting screw adjusts the size of the space inside the sleeve.

[0011] Furthermore, the movable frame includes a slide block with rollers inside. A cable passes through the inside of the slide block and is located directly below the rollers. The slide block slides along the cable via the rollers.

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

[0013] Furthermore, a lifting ring is fixed to the base for suspending and moving the mobile frame.

[0014] Furthermore, the hook head has a bent portion with an angle of 55°-125°.

[0015] The beneficial effects of this invention are:

[0016] This fixture includes a movable frame and a cable. The movable frame slides along the cable, and a self-release hook is hinged to the bottom of the movable frame. The self-release hook includes a hook head and a sinking head, which 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 attached to the hook head, and a cable is fixed to the automatic opening ring. When the tension of the cable is released, the sinking head is driven by gravity to lift the hook head and disengage from the automatic opening ring. After disengagement, the automatic opening ring automatically opens under gravity to release the cable. This fixture combines a movable frame and a self-release hook, and the self-release hook and the automatic opening ring work together. Utilizing gravity, only the tension of the cable needs to be released to automatically release the cable hoisting and fixing, eliminating the need for manual removal one by one, thus improving construction efficiency and ensuring construction safety.

[0028] To better understand the purpose, structure, and function of this invention, the following detailed description of a specific embodiment of the invention, "A Composite Cable Installation Clamping Fixture Suitable for Horizontal Construction of Guide Frames," is provided in conjunction with the accompanying drawings.

[0029] See Figure 1 and Figure 2In this embodiment, the tooling includes a movable frame 100 and a sliding cable 200. The movable frame 100 slides along the sliding cable 200. A self-detaching hook 300 is hinged to the bottom of the movable 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 the weight of the hook head 301. The bottom of the movable frame 100 is hinged to the rotating part 303. An automatic opening ring 400 is attached to the hook head 301, and a cable 500 is fixedly attached to the automatic opening ring 400. After the moving frame 100 slides along the cable 200 to transport the cable 500 to the corresponding position and install it, the operator operates the pulley of the cable 200 to release the tension of the cable 200. At this time, the sinking head 302 sinks under the influence of gravity, which in turn drives the hook head 301 to rise, so that the hook head 301 is disengaged from the automatic opening ring 400. After being disengaged, the automatic opening ring 400 will automatically open and detach from the cable 500 under the action of gravity. The entire disengagement process does not require the operator to work at height. Only by remotely releasing the tension of the cable 200, all the cable 500 hoisting positions on the cable 200 can be automatically disengaged and released from the attachment state. The automatic opening ring 400 automatically falls off the cable 500 and is automatically retrieved. This tooling is not only highly efficient in disengagement and retrieval, but also safer.

[0030] See further Figure 2 In this embodiment, the automatic opening ring 400 includes a first half-ring 401 and a second half-ring 402. The first half-ring 401 includes a first hinge end 4011 and a first hook end 4012. The second half-ring 402 includes a second hinge end 4021 and a second hook end 4022. The first hinge end 4011 and the second hinge end 4021 are hinged together. Both the first hook end 4012 and the second hook end 4022 are provided with hook interfaces 403. The first hook end 4012 and the second hook end 4022 rotate along the hinge end to abut / move away from each other, thereby closing / opening the automatic opening ring 400. When the automatic opening ring 400 closes... When the first hook end 4012 and the second hook end 4022 are aligned, the hook head 301 passes through the hook interface 403 of the first hook end 4012 and the second hook end 4022 to hook the automatic opening ring 400 and restrict the automatic opening ring 400 from opening under gravity. Only when the hook head 301 is unhooked from the hook interface 403, the first half ring 401 and the second half ring 402 rotate relative to each other under gravity, opening the automatic opening ring 400 and detaching from the cable 500, automatically releasing the restraint on the cable 500, and achieving the purpose of automatically retrieving the opening ring 400.

[0031] More specifically, in this embodiment, the tooling also includes a sleeve 501, which is sleeved and fixed on the cable 500. The outer wall of the sleeve 501 is provided with a sleeve groove 502 along the circumferential direction. 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 and to strengthen the sleeve fixation of the cable 500. In addition, 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 hoisting and movement.

[0032] See further Figure 3 In this embodiment, the sleeve 501 is provided with a fastening screw 503 perpendicular to the axis of the cable 500. Tightening the fastening screw 503 causes the top of the fastening screw 503 to abut against and fix 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-tube 504 and a second half-tube 505. The first half-tube 504 and the second half-tube 505 are detachably and fixedly connected to form the sleeve 501 via a locking adjustment component. The operator can adjust the distance between the first half-tube 504 and the second half-tube 505 by adjusting the locking adjustment component, thereby adjusting the size of the internal space of the sleeve 501. Preferably, the locking adjustment component includes a locking nut 506 and an adjusting screw 507. Both ends of the first half-tube 504 and the second half-tube 505 are provided with locking holes 508. The adjusting screw 507 passes through the locking holes 508 of the first half-tube 504 and the second half-tube 505 and is detachably and fixedly connected to the locking nut 506. The operator can adjust the size of the internal space of the sleeve 501 by tightening / loosening the adjusting screw 507 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 inside the slide 101. The zipline 200 passes through the left side of the slide 101 and exits from the right side, passing directly below the roller 102. Preferably, the two rollers 102 are arranged to be distributed left and right on the same straight line. The slide 101 slides along the zipline 200 through the roller 102. The rolling reduces the friction during sliding, making the movable frame 100 slide more stably and smoothly on the zipline 200.

[0035] More specifically, in this embodiment, a vertically downward connecting rod 103 is fixedly connected to the bottom of the slide 101. 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. Furthermore, the connecting rod 103 can be made detachable. By replacing the connecting rod 103 with different lengths, this tooling can be adapted to different application scenarios.

[0036] See further Figure 2 In this embodiment, the hook head 301 has a hook portion 3011 with an angle of 55°-125°. This ensures that the hook head 301 will not be affected by natural wind and suddenly detach when it is attached to the automatic opening ring 400, and also ensures that it can be easily detached after the tension of the cable 200 is released.

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