Description

Technical Field

[0001] This utility model relates to the field of umbilical cable technology, and specifically to a limiting device for umbilical cable release. Background Technology

[0002] Umbilical cables are core equipment for deepwater oil and gas exploration and development. They typically integrate functional modules such as power, communication, and hydraulic pipelines to connect surface facilities with underwater production systems, enabling energy transmission, signal control, and chemical delivery. They are widely used in underwater production systems, ROVs (Remotely Operated Vehicles), and deep-sea robots.

[0003] Existing umbilical cables are generally heavier than conventional cables. During release, especially in the lowering phase, they are prone to accelerating downwards due to inertia and gravity caused by the rotation of the cable. This can easily lead to the cable release wheel spinning faster and faster, resulting in a runaway speed and irreversible damage to precision structures such as cables. Therefore, a limiting device for umbilical cable release is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a limiting device for umbilical cable release, which integrates deceleration braking and static locking into one limiting function. This improves the safety and stability of umbilical cable release, and ensures that the release speed is within human control through auxiliary deceleration, avoiding sudden pulling and rapid lowering.

[0005] The technical solution adopted by this utility model to solve its technical problem is a limiting device for umbilical cable release, including a base, a cable release wheel and a limiting braking mechanism. Support arms are welded to both ends of the top of the base, the cable release wheel is disposed between the support arms, brake disc assemblies are disposed at both ends of the cable release wheel, and two sets of limiting braking mechanisms are disposed and located at the bottom of the brake disc assemblies.

[0006] The two ends of the cable-laying wheel are rotatably connected to the top of the support arm via bearings, and the brake disc assembly is respectively sleeved on the two ends of the cable-laying wheel.

[0007] By adopting the above technical solution, a cable release limit device is provided for the release of umbilical cable through a mechanism consisting of a base, a cable release wheel, and a limit braking mechanism. This device can assist in slowing down the cable release wheel during cable release, and then further limit and lock the cable release wheel after it has slowed down and stopped rotating, keeping the cable release wheel in a stopped state when no cable is being released, thereby improving the stability of umbilical cable use.

[0008] Specifically, the brake disc assembly includes a central disc with toothed lobes on its outer periphery. The center of the central disc is fixedly connected to the shaft of the cable release wheel by a key pin. Circular side discs are bolted to both sides of the central disc.

[0009] Specifically, the limiting braking mechanism includes a base plate and a limiting plate with teeth corresponding to the middle plate on the top. The bottom of the limiting plate is welded to the middle of the top of the base plate. A wheel frame is provided on the top of the base plate and on both sides of the limiting plate. A rubber wheel is provided in the wheel frame. The two ends of the rubber wheel are rotatably connected to the wheel frame through a damping shaft.

[0010] By having the rubber wheel in the limit braking mechanism contact the circular side disc of the rotating brake disc assembly, and with the assistance of the damping effect of the damping shaft, a certain frictional resistance is generated. This resistance can counteract the rotational inertia of the cable release wheel, promote its deceleration, and prevent the cable release wheel from becoming uncontrollable due to the weight of the umbilical cable causing it to rotate faster and faster into a "runaway" state.

[0011] Specifically, guide rods are welded to both ends of the bottom of the wheel frame, the bottom of the guide rods extends through to the bottom of the base plate, and a spring is sleeved on the top of the guide rods. The two ends of the springs are welded to the wheel frame and the base plate, respectively.

[0012] By adopting the above technical solution, the limit braking mechanism brakes the brake disc assembly to limit the cable-laying wheel, thereby stopping the umbilical cable from being laid.

[0013] Specifically, telescopic push rods are installed at both ends of the base, and the output end of the telescopic push rods is connected to the bottom of the base plate.

[0014] By adopting the above technical solution, the telescopic push rod provides lifting and pulling force to the limit braking mechanism.

[0015] The beneficial effects of this utility model are as follows: The mechanism composed of a base, a cable-laying wheel, and a limiting braking mechanism provides a cable-laying limiting device for releasing the umbilical cable. It can assist in slowing down the cable-laying wheel during cable laying, and then further limit and lock the cable-laying wheel after it stops rotating, maintaining the cable-laying wheel in a stopped state when no cable is being laid. This realizes the limiting function of integrating deceleration braking and static locking into one unit, which can improve the safety and stability of umbilical cable release. The assisted deceleration ensures that the release speed is within human control, avoiding sudden pulling and rapid descent. It solves the problem that during the release process of the umbilical cable, especially in the descent stage, the cable-laying wheel is prone to accelerate downward due to inertia and gravity, which can easily cause the cable-laying wheel to rotate faster and faster, resulting in a runaway speed and irreversible damage to the cable and other precision structures.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-4 As shown, the present invention provides a limiting device for releasing umbilical cables, comprising a base 1, a cable-releasing wheel 2, and a limiting braking mechanism 3. Support arms 11 are welded to both ends of the top of the base 1, the cable-releasing wheel 2 is disposed between the support arms 11, and brake disc assemblies 21 are provided at both ends of the cable-releasing wheel 2. The limiting braking mechanism 3 is provided in two sets and is located at the bottom of the brake disc assembly 21.

[0024] The two ends of the cable-laying wheel 2 are rotatably connected to the top of the support arm 11 via bearings, and the brake disc assembly 21 is respectively sleeved on the two ends of the cable-laying wheel 2.

[0025] The present invention also includes a brake disc assembly 21 comprising a central disc 211 with toothed outer periphery, the center of the central disc 211 being fixedly connected to the shaft of the cable release wheel 2 by a key pin, and circular side discs 212 being bolted to both sides of the central disc 211.

[0026] This utility model also includes a limiting braking mechanism 3 comprising a base plate 31 and a limiting plate 32 with a toothed edge on the top corresponding to the middle plate 211. The bottom of the limiting plate 32 is welded to the middle of the top of the base plate 31. A wheel frame 33 is provided on the top of the base plate 31 and on both sides of the limiting plate 32. A rubber wheel 34 is provided inside the wheel frame 33. The two ends of the rubber wheel 34 are rotatably connected to the wheel frame 33 through a damping shaft 35.

[0027] When in use, based on the contact between the rubber wheel 34 in the limit braking mechanism 3 and the circular side plate 212 of the rotating brake disc assembly 21, and with the damping effect of the damping shaft 35, a certain frictional resistance is generated. This resistance can counteract the rotational inertia of the cable release wheel 2, promote its deceleration, and prevent the cable release wheel 2 from becoming uncontrollable due to the weight of the umbilical cable causing it to rotate faster and faster into a "runaway" state.

[0028] After the cable release wheel 2 comes to a complete stop, the limiting plate 32 is pushed further to engage with the teeth of the middle disc 211 of the brake disc assembly 21. During this process, the cable release wheel 2 can be manually rotated for fine adjustments to ensure that the teeth of the middle disc 211 are engaged with the limiting plate 32. Then, the limiting plate 32 is pushed up to lock the middle disc 211 in place. This mechanical hard locking ensures that the cable release wheel can rotate again, thus guaranteeing the stability of the umbilical cable after release.

[0029] The present invention also includes a guide rod 36 welded to both ends of the bottom of the wheel frame 33, the bottom of the guide rod 36 extending through to the bottom of the base plate 31, and a spring 37 sleeved on the top of the guide rod 36, the two ends of the spring 37 being welded to the wheel frame 33 and the base plate 31 respectively.

[0030] When in use, the limit braking mechanism 3 brakes the brake disc assembly 21 to limit the cable release wheel 2, thereby stopping the umbilical cable from being released.

[0031] This utility model also includes telescopic push rods 38 installed at both ends of the bottom of the base 1, and the output end of the telescopic push rods 38 is connected to the bottom of the base plate 31.

[0032] During use, the telescopic push rod 38 provides lifting and pulling force to the limit braking mechanism 3.

[0033] In use, the base 1 is mounted on the platform where the cable to be released is to be installed, and the power supply components in the work area provide power to the electrical mechanism of this application. During cable release, the umbilical cable is released by rotating the cable release wheel 2. When the cable release is about to end or when it is necessary to prevent the cable release wheel 2 from accelerating, the bottom plate 31 of the limit braking mechanism 3 is pushed up by the telescopic push rod 38, causing the rubber wheel 34 to rise and contact the circular side plate 212 of the brake disc assembly 21. Based on the damping effect of the rubber wheel 34, the rotation speed of the cable release wheel 2 is controlled. At the same time, the spring 37 provides a certain elastic margin to prevent the rubber wheel 34 from initially contacting the circular side plate 212. 12 generates a large rigid lifting force. After the rotation of the cable-laying wheel 2 gradually slows down and stops, the bottom plate 31 is pushed up further, so that the limiting plate 32 is engaged in the teeth of the middle plate 211 of the brake disc assembly 21. During this process, the cable-laying wheel 2 can be manually rotated for fine adjustment. After the teeth of the middle plate 211 are engaged with the limiting plate 32, the limiting plate 32 is pushed up to lock the middle plate 211. This mechanical hard locking can ensure that the cable-laying wheel can rotate again, ensuring the stability after the umbilical cable is released. It achieves anti-acceleration during the dynamic cable-laying process and anti-slip effect in the static state when the cable is stopped, increasing the safety of the umbilical cable release operation.

[0034] Furthermore, the telescopic push rod 38 can be an electric push rod or a hydraulic push rod, and its specific use is determined according to actual operational requirements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
