Description

Technical Field

[0001] The utility model relates to the technical field of cable pulling auxiliary devices, and specifically to a hydraulic cylinder push rod clamping type actively driven submarine cable pulling auxiliary device. Background Art

[0002] Submarine cables primarily refer to long-distance power grid connections laid across waters between land and islands, between islands, and between oil production platforms. The dense network of protected areas, waterways, and anchorages in the Bohai Sea, where the Bohai Oilfield shore power project is being implemented, severely restricts the layout and laying of submarine cables. To avoid disturbing the terrain and landforms during cable-laying construction and reduce adverse impacts on the surrounding marine ecosystem, seabed excavation is typically avoided within areas less than 250 meters from the protected area red line, and horizontal directional drilling combined with crossing construction is employed. In these circumstances, shore power projects often face crossings involving submarine cables exceeding a kilometer in length. When dragging a submarine cable within a steel conduit, the traction applied to the cable significantly exceeds its maximum allowable tensile strength to offset the friction between the cable and the inner wall of the conduit over a kilometer of contact, potentially causing mechanical damage. Therefore, a hydraulic cylinder push rod clamping, actively driven submarine cable dragging auxiliary device is proposed to address this issue. Utility Model Content

[0003] The purpose of the utility model is to provide a hydraulic cylinder push rod clamping type active drive submarine cable dragging auxiliary device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a hydraulic cylinder push rod clamping type active drive submarine cable pulling auxiliary device, comprising a pushing mechanism, a movable overall frame, a hydraulic transmission system and a main rolling wheel transmission mechanism;

[0005] The overall frame includes two circular ring components, and a channel for the cable to pass through is formed between the two circular ring components. The pushing mechanism is installed between the two circular ring components, and the pushing mechanism includes a first load-bearing frame and a second load-bearing frame that are symmetrically fixedly connected. Two pushing mechanism connecting plates are symmetrically fixedly connected at a position between the first load-bearing frame and the second load-bearing frame. A transmission beam is fixedly connected to the bottom of the second load-bearing frame. The two pushing mechanism connecting plates are rotatably connected to clamping arms on opposite sides of each other. A rotating crank is rotatably connected between the inner wall of the clamping arm and the transmission beam. Pushing frames are installed at both ends of the transmission beam, and the hydraulic transmission system is connected to the pushing frames.

[0006] Preferably, a hydraulic pump frame load-bearing plate is installed at the bottom end of the inner part of the overall frame, and the circular ring component includes three 120-degree fan rings and three fan ring connecting rods. The three 120-degree fan rings are equidistantly distributed in a circular array, and the fan ring connecting rod is fixedly connected between two adjacent 120-degree fan rings. One side of the hydraulic pump frame load-bearing plate is fixedly connected to the fan ring connecting rod, and the outer side of the fan ring connecting rod is fixedly connected to the hydraulic pump frame load-bearing plate rear plate, and the hydraulic pump frame load-bearing plate rear plate is fixedly connected to the hydraulic pump frame load-bearing plate. The hydraulic pump frame is fixedly connected to the hydraulic pump frame rear plate above the hydraulic pump frame load-bearing plate, and the hydraulic pump frame is fixedly connected to the hydraulic pump frame rear plate above the hydraulic pump frame, and the hydraulic pump frame and one side of the hydraulic pump frame rear plate are both fixedly connected to the fan ring connecting rod, and two circular connecting frames are sleeved on the circumference of the fan ring connecting rod.

[0007] Preferably, a secondary rolling wheel is sleeved on the circumferential surface of the fan ring connecting rod, and the secondary rolling wheel is located between the two circular ring connecting frames.

[0008] Preferably, two supporting members are installed at the bottom of the two circular ring members, and main rolling wheel transmission mechanisms for driving the circular ring members to move are installed on the two supporting members.

[0009] Preferably, the supporting member comprises a main rolling wheel upper frame and a main rolling wheel lower frame that are fixedly connected.

[0010] Preferably, the main rolling wheel transmission mechanism includes a hydraulic motor and a main rolling wheel, and the output end of the hydraulic motor is connected to the main rolling wheel.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model controls four groups of hydraulic cylinders to push up the transmission crossbeam of the pushing mechanism. Since the pushing mechanism is a hinge transmission mechanism, the clamping arm is driven by the hinge mechanism to clamp the cable, and the gear hydraulic motors that control the front and rear main rolling wheels drive the main rolling wheels to complete the dragging of the cable. At the same time, the two upper slave rolling wheels assist the cable movement to prevent the main rolling wheels from slipping and shifting. During the dragging, the main rolling wheels play the role of converting sliding friction into rolling friction. Secondly, since the main rolling wheels are designed as cantilever beams and are not directly installed on the annular frame, when the cable is dragged, the main rolling wheel connecting frame is an elastic rigid body and can withstand certain bending deformation. Therefore, the rolling wheels can adapt to certain changes in the inner diameter of the pipe during movement, thereby preventing the entire mechanism from being stuck in extreme environments, thereby improving the cable dragging efficiency and stability during dragging.
