Description

Technical Field

[0001] The utility model relates to the field of marine engineering machinery, and particularly relates to an offshore towing device. Background Art

[0002] In the existing ship scientific research operations, when it is necessary to lower scientific research devices or other terminal equipment using a gantry system, the stability and angle control of the gantry become key elements. In traditional technologies, the gantry is mainly fixed at the extreme positions of the rotation stroke through mechanical limit devices to ensure that it maintains a preset towing angle. However, this design has the following defects and deficiencies:

[0003] Singularity of angle adjustment: With the diversification of scientific research operation requirements, different scenarios may require the gantry to work at different angles and postures. However, the gantry can only be limited at the preset extreme positions and lacks the ability to be fixed at intermediate angles, thus limiting its applicability in different scientific research tasks.

[0004] Uneven load distribution: In the towing state, most of the loads are directly borne by the leg structure, which poses higher requirements on the overall strength of the main structure. In the long-term operation, it may lead to structural fatigue and potential safety hazards.

[0005] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0009] To solve the above technical problems, the utility model provides the following technical solutions:

[0010] An offshore towing device, comprising:

[0011] A base provided with a first support portion and a second support portion;

[0012] Legs, the legs comprising a leg main body and an auxiliary support fixedly connected to the leg main body, and the leg main body is rotatably connected to the base;

[0013] The flap mechanism includes a support plate and a driving component connected to each other. The support plate is rotatably connected to the base, and the driving component is disposed on the base and is used to drive the support plate to rotate relative to the base.

[0014] Wherein, when the support plate rotates to the rotation path of the auxiliary support and supports on the first support portion, the auxiliary support can rotate with the leg body and abut against the support plate, so that the leg body is limited relative to the base at a first angle.

[0015] When the support plate rotates away from the rotation path of the auxiliary support, the auxiliary support can rotate with the leg body and abut against the second support portion, so that the leg body is limited relative to the base at a second angle.

[0016] In some embodiments, the base is provided with a groove, and the extending direction of the groove is the same as the rotation direction of the auxiliary support; the first support portion is disposed at the notch of the groove, the second support portion is disposed at the bottom of the groove, and the support plate is rotatably disposed at the notch.

[0017] In some embodiments, a nylon backing plate is provided on the support plate and / or the first support portion; when the support plate rotates and supports on the first support portion, the support plate and the first support portion are in contact through the nylon backing plate.

[0018] In some embodiments, the base is provided with a groove, and the extending direction of the groove is the same as the rotation direction of the auxiliary support; the first support portion is disposed at the notch of the groove, the second support portion is disposed at the bottom of the groove, and the support plate is rotatably disposed at the notch; a nylon backing plate is provided on each of the opposite sides of the notch of the groove, the support plate is provided with a positioning convex block, and each of the opposite sides of the positioning convex block is provided with an inclined surface and a supporting plane.

[0023] (III) Advantageous Effects

[0024] Compared with the prior art, the marine towing device provided by the present utility model has the following advantageous effects:

[0025] When the marine towing device is working, the rotation limit of the leg is controlled by the flap mechanism. Specifically, the leg can rotate through the leg body, driving the auxiliary support to rotate. When the support plate rotates to the rotation path of the auxiliary support and supports on the first support part, the auxiliary support can rotate with the leg body and abut against the support plate, limiting the leg body relative to the base at the first angle; when the support plate rotates away from the rotation path of the auxiliary support, the auxiliary support can rotate with the leg body and abut against the second support part, limiting the leg body relative to the base at the second angle. Among them, the load and wave impact on the leg can be transmitted by the auxiliary support to the base, effectively reducing the fluctuating load borne by the driving components and the main structure, and reducing the probability of risks caused by the fluctuating load. It can be seen that compared with the traditional gantry with only a single working angle, the marine towing device of the present utility model can increase the number of gantry limit positions, improve the applicability of the gantry at the working angle, and at the same time can reduce the load directly borne by the main structure, having the advantages of high safety and good applicability in towing operations.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Existing gantries for offshore towing usually only fix the angle at the extreme positions of the rotation stroke. At this time, the leg structure directly bears the load, and greater structural strength requirements are imposed on the main structure.

[0037] To solve the above technical problems, this embodiment provides an offshore towing device. Please refer to Figures 1 to 4 as shown, Figure 1 is a perspective view of the offshore towing device in the embodiment, Figure 2 is a perspective view of the flap mechanism in the embodiment, Figure 3 is a schematic diagram of the offshore towing device in the embodiment when the leg main body is at the first angle, Figure 4 is a schematic diagram of the offshore towing device in the embodiment when the leg main body is at the second angle.

[0038] An offshore towing device in this embodiment includes: a base 1, legs 2, and a flap mechanism 3.

[0039] As Figure 2 shown, the base 1 is provided with a first support portion 11 and a second support portion 12 for supporting the legs 2. It can be understood that the base 1 is usually fixed on the ship.

[0040] As Figure 2 shown, the leg 2 includes a leg main body 21 and an auxiliary support 22 fixedly connected to the leg main body 21. The leg main body 21 is rotatably connected to the base 1, enabling the leg main body 21 to rotate relative to the base 1 and the ship. It can be understood that, as Figure 1 shown, a cross beam is fixedly connected between the legs 2, and the cross beam is used for hoisting scientific research devices.

[0041] As Figure 2 shown, the flap mechanism 3 includes a support plate 31 and a drive component 32 connected to each other. The support plate 31 is rotatably connected to the base 1, and the drive component 32 is disposed on the base 1 and is used to drive the support plate 31 to rotate relative to the base 1.

[0042] Among them, the setting of the flap mechanism 3 also needs to meet the following conditions: As Figure 3As shown, when the support plate 31 rotates to the rotation path of the auxiliary support 22 and supports on the first support portion 11, the auxiliary support 22 can rotate with the leg main body 21 and abut against the support plate 31, so that the leg main body 21 is limited to a first angle relative to the base 1; as Figure 4 shown, when the support plate 31 rotates away from the rotation path of the auxiliary support 22, the auxiliary support 22 can rotate with the leg main body 21 and abut against the second support portion 12, so that the leg main body 21 is limited to a second angle relative to the base 1.

[0043] In the above technical solution of the offshore towing device, during the working process, the innovative flap mechanism 3 realizes precise control of the rotation position of the leg 2 and multiple limit positions. Specifically, when the support plate 31 rotates to the preset cooperation position with the auxiliary support 22 and stably supports on the first support portion 11 of the base 1, the auxiliary support 22 can automatically abut against the support plate 31 as the leg main body 21 rotates, thereby effectively limiting the leg main body 21 to the preset first angle and ensuring the stability of the gantry under specific working conditions. When the support plate 31 rotates to avoid the rotation path of the auxiliary support 22, the auxiliary support 22 then smoothly abuts against the second support portion 12 as the leg main body 21 continues to rotate, thereby limiting the leg main body 21 to another preset second angle, thus improving the adaptability and operation flexibility of the gantry. Particularly importantly, the offshore towing device of the above technical solution cleverly uses the auxiliary support 22 as a bridge for load transfer, effectively dispersing and transferring the wave impact and working load borne by the leg 2 to the base 1, significantly reducing the fatigue damage of the driving component 32 and the leg main body 21 caused by directly bearing the fluctuating load, thereby reducing the risk of failure or malfunction caused by the fluctuating load. This innovative design not only enhances the structural strength and service life of the gantry, but also significantly improves the safety and reliability of the towing operation.

[0044] It can be seen that compared with the traditional gantry that can only perform simple limit at the extreme positions, the offshore towing device of the above technical solution realizes more precise control of the position of the leg 2 and more effective load management by adding additional limit positions and optimizing the load transfer path, endowing the gantry with a wider range of applicability and higher operation efficiency, which is an important progress in the field of offshore towing technology.

[0045] In one implementation manner of the above base 1 provided with the first support portion 11 and the second support portion 12, refer to Figure 2 and Figure 4As shown, the base 1 is provided with a groove 10, and the extending direction of the groove 10 is the same as the rotation direction of the auxiliary support 22, that is, it is adapted to the rotation path of the auxiliary support 22; the first support portion 11 is provided at the notch of the groove 10, the second support portion 12 is provided at the bottom of the groove 10, and the support plate 31 is rotatably provided at the notch. The design of the groove 10 optimizes the structural layout of the gantry, making the overall structure more compact, effectively reducing the space occupation, especially suitable for the environment with limited space in offshore operations, and improving the space utilization rate. At the same time, the first support portion 11 is arranged at the notch of the groove 10, and the support plate 31 is rotatably arranged and cooperates with it. The notch structure strengthens the support of the first support portion 11 on the support plate 31 and improves the stability during cooperation.

[0046] Exemplarily, the groove wall of the groove 10 is an integral structure (not shown in the figure), or is formed by enclosing several rib plates.

[0047] In an embodiment where the support plate 31 abuts against the first support portion 11, refer to Figure 2 As shown, a nylon cushion plate 4 is provided on the support plate 31 and / or the first support portion 11; when the support plate 31 rotates and supports on the first support portion 11, the support plate 31 contacts the first support portion 11 through the nylon cushion plate 4. With this arrangement, the nylon cushion plate 4 is innovatively added to the support plate 31 and the first support portion 11, which can buffer the load and impact, improve the stability of the cooperation, and at the same time can reduce the direct friction and wear between the support plate 31 and the first support portion 11, effectively reducing the component loss caused by long-term use, thereby significantly extending the service life of the offshore towing device and reducing the maintenance cost.

[0048] Exemplarily, the nylon cushion plate 4 is fixed on the plate surface of the support plate 31 and / or the first support portion 11 by means of bonding or screw fixation.

[0049] The above groove 10 and nylon cushion plate solutions can be combined and further optimized as follows. Refer to Figure 2 As shown, the base 1 is provided with a groove 10, and the extending direction of the groove 10 is the same as the rotation direction of the auxiliary support 22; the first support portion 11 is provided at the notch of the groove 10, the second support portion 12 is provided at the bottom of the groove 10, and the support plate 31 is rotatably provided at the notch; a nylon cushion plate 4 is provided on each of the opposite sides of the notch of the groove 10, the support plate 31 is provided with a positioning convex block 310, and each of the opposite sides of the positioning convex block 310 is provided with an inclined surface 311 and a support plane 312, and the whole is symmetrically structured. The distance between the inclined surfaces 311 gradually decreases towards the end for guiding the positioning convex block 310 to be inserted between the nylon cushion plates 4; when the support plate 31 rotates and supports on the first support portion 11, the support plate 31 contacts the first support portion 11 through the nylon cushion plate 4, the positioning convex block 310 is limited between the nylon cushion plates, and contacts the nylon cushion plate 4 through the support plane 312.

[0050] In one embodiment of the auxiliary support 22 abutting against the support plate 31, see Figure 2 and Figure 3 As shown, the support plate 31 is provided with a nylon pad 4 at one end that abuts against the auxiliary support 22, and the nylon pad 4 is used for buffering and shock absorption, while avoiding direct contact between the auxiliary support 22 and the support plate 31, thereby extending the service life.

[0051] Exemplarily, the nylon pad 4 is mounted on the support plate 31 by screws or buckles and can be removed and replaced.

[0052] In one embodiment of the above-mentioned support plate 31 being rotatably connected to the base 1, see Figure 2 As shown, the support plate 31 and the base 1 are rotatably connected via a pin shaft, and the support plate 31 can rotate around the pin shaft.

[0053] In one embodiment of the driving component 32 driving the support plate 31 to rotate, see Figure 2 and Figure 3 As shown, the driving component 32 is a tilting cylinder, one end of which is rotatably connected to the base 1 , and the other end of which is rotatably connected to the support plate 31 .

[0054] In another embodiment in which the driving component 32 drives the support plate 31 to rotate, the driving component 32 is a rotating driving component 32 such as a motor, the support plate 31 is connected to the base 1 through a rotating shaft, and the motor is connected to the rotating shaft for driving the rotating shaft to rotate, thereby driving the support plate 31 to rotate.

[0055] The first angle and the second angle can be set according to the requirements of the towing operation. For example, the first angle is 150° and the second angle is 170°.

[0056] In order to conveniently view the rotation angle of the leg body 21, refer to Figure 2 As shown, the base 1 is provided with a dial 5 indicating an angle at the rotation connection with the leg body 21 , and the leg body 21 is provided with a pointer 6 facing the dial 5 , and the pointer 6 can indicate the current relative angle between the leg body 21 and the base 1 on the dial 5 .
