Description

Technical Field

[0001] This invention relates to the field of cable turntable technology, specifically to a high-load-bearing turntable top brake structure and layout. Background Technology

[0002] Chinese patent CN208980043U discloses an auxiliary placement support structure for cable construction, including a base with several casters mounted on the lower end and two parallel mounting columns on the upper end. A fixing plate is welded between the mounting columns, and a motor is mounted on the bottom of the fixing plate. The casters allow for easy movement of the entire device; the motor enables the turntable to rotate, thus allowing the turntable to hold cables; the fixing plate protects the motor; the placement plate allows for the placement and retrieval of support rods; the support feet support the cables; a spiral telescopic rod allows for height adjustment of the support feet as needed; and a rotating shaft, in conjunction with adjusting bolts, allows for angle adjustment of the support angle rods. When not in use, the support angle rods are retracted into grooves.

[0003] In the existing technology, the turntable is set on the hull. However, when the turntable is not in operation, it will be subjected to strong winds and waves, causing it to tilt. This tilting will cause the supporting structure on the turntable to twist, resulting in a reduction in the lifespan of the turntable. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned above in the background art, and to propose a high load-bearing turntable top brake structure and layout.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A high-load-bearing turntable top brake structure includes a hull and a top brake mechanism. A turntable is mounted on the hull, and a top brake mechanism is disposed between the turntable and the hull. The top brake mechanism includes:

[0007] Mounting base, the vertical end of the mounting base is rotatably provided with a mounting bracket, and a top brake plate is movably provided on the mounting bracket;

[0008] A linear drive mechanism is provided at the end of the horizontal part of the mounting base. The output end of the linear drive mechanism passes through the mounting base and is connected to the support roller, which is located inside the end of the mounting frame.

[0009] As a further aspect of the present invention, a friction plate is provided on the top surface of the top brake plate.

[0010] As a further aspect of the present invention, the end of the mounting frame is provided with a groove adapted to the support roller.

[0011] As a further aspect of the present invention, multiple top brake mechanisms are provided on the hull.

[0012] As a further aspect of the present invention, the number of top brake mechanisms is 72.

[0013] A layout for a high-load-bearing turntable top brake structure, characterized by comprising:

[0014] The top brake mechanism has multiple rings, and each ring has multiple rings.

[0015] As a further aspect of the present invention: the number of rings is 5, with 6, 12, 18, 18, and 18 rings arranged sequentially in each ring from the inside out.

[0016] As a further aspect of the present invention, the number of top brake mechanisms arranged along the bow direction is less than the number of top brake mechanisms arranged along the vertical direction of the bow.

[0017] The beneficial effects of this invention are:

[0018] When the turntable is not in a construction state and there are large waves, the present invention will control the hydraulic cylinder to work, drive the top brake plate on the mounting frame to rotate and lift along the mounting base, so that the top brake plate acts on the bottom surface of the turntable, thereby ensuring that the turntable always remains in a horizontal state when encountering large waves during the non-construction process of the ship, effectively preventing the turntable from being damaged during non-construction.

[0019] The present invention features an asymmetrical layout of the top brake mechanism. By taking advantage of the fact that the waves are larger on both sides of the bow and smaller in front and behind the hull during navigation, the number of top brake mechanisms can be reduced as much as possible, thereby achieving the effect of correcting the turntable and maintaining its horizontal operation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figure 1-4 As shown, the present invention is a high load-bearing turntable 2 top brake structure, including a hull and a top brake mechanism 1;

[0029] A turntable 2 is installed on the hull. The turntable 2 is used to retrieve or release cables. A top brake mechanism 1 is installed between the turntable 2 and the hull. The top brake mechanism 1 is used to lift and support the turntable 2, so that the turntable 2 is always in a relatively horizontal state. It can protect the support structure of the turntable 2 installed on the hull. It effectively solves the problem that the turntable 2 is installed on the hull. However, when the hull is transported on lakes and seas, it will encounter large winds and waves. These winds and waves will act on the turntable 2, causing it to tilt. The tilting of the turntable 2 will cause the support structure installed on the turntable 2 to twist. Working in such a large wind and wave environment for a long time will result in a short service life of the turntable 2.

[0030] Specifically, the connection between the turntable 2, the hull, and the top brake mechanism 1 is as follows: a ring-shaped ship engine base plate 3 is provided on the hull, a turntable track plate 4 is provided on the bottom surface of the turntable 2, the turntable track plate 4 is adapted to the ship engine base plate 3, and the top brake mechanism 1 is located between the turntable track plate 4 and the ship engine base plate 3 and is installed on the ship engine base plate 3.

[0031] Multiple top brake mechanisms 1 are provided on the hull; preferably, there are 72 top brake mechanisms 1.

[0032] The top brake mechanism 1 includes a mounting base 11, a linear drive mechanism, a support roller 13, a mounting frame 14, a top brake plate 15, and a friction plate 16. The mounting base 11 is mounted on the hull and has an L-shaped structure. The mounting frame 14 is rotatably mounted on the vertical end of the mounting base 11. The top brake plate 15 is movably mounted on the mounting frame 14. The friction plate 16 is mounted on the top surface of the top brake plate 15. The linear drive mechanism is mounted on the horizontal end of the mounting base 11. The output end of the linear drive mechanism passes through the mounting base 11 and is connected to the support roller 13. The support roller 13 is located inside the end of the mounting frame 14. The end of the mounting frame 14 is provided with a groove that is adapted to the support roller 13.

[0033] The linear drive mechanism in the top brake mechanism 1 is connected to the level monitoring instrument on the turntable 2. When the level monitoring instrument on the turntable 2 detects that the turntable 2 is tilted, it will control the linear drive mechanism to work, drive the top brake plate 15 on the mounting frame 14 to rotate and lift, and support the turntable 2.

[0034] The linear drive mechanism includes hydraulic cylinder 12, pneumatic cylinder, lead screw mechanism, linear motor, etc.

[0035] The top brake plate 15 in the top brake mechanism 1 is connected to the bottom surface of the turntable 2. By setting the friction plate 16 on the top brake plate 15, the friction between the top brake plate 15 and the turntable 2 can be increased, making the support of the top brake plate 15 more stable and firm.

[0036] During operation, when the turntable 2 is not in a construction state and in rough seas, the present invention will control the hydraulic cylinder 12 to drive the top brake plate 15 on the mounting frame 14 to rotate and lift along the mounting base 11, so that the top brake plate 15 acts on the bottom surface of the turntable, thereby ensuring that the turntable 2 remains in a horizontal state when encountering rough seas during non-construction periods, effectively preventing damage to the turntable 2 during non-construction periods.

[0037] Example 2

[0038] Based on the above embodiment 1, the present invention provides a layout for a high load-bearing turntable top brake structure, comprising the following:

[0039] The top brake mechanism 1 has multiple rings, and each ring has multiple rings. Preferably, there are 5 rings, and each ring has 6, 12, 18, 18 and 18 rings respectively from the inside out.

[0040] Furthermore, the number of top brake mechanisms 1 arranged along the bow direction is less than the number of top brake mechanisms 1 arranged vertically along the bow direction. This asymmetrical arrangement of the number of top brake mechanisms 1 utilizes the fact that the waves are larger on both sides of the bow and smaller in front and behind the bow when the ship is sailing, thus minimizing the number of top brake mechanisms 1 and achieving the effect of correcting the turntable 2 and maintaining its horizontal operation.

[0041] The working principle of this invention is as follows: When the turntable 2 is not in a construction state and there are large waves, the control cylinder 12 will be activated to drive the top brake plate 15 on the mounting frame 14 to rotate and lift along the mounting base 11. This allows the top brake plate 15 to act on the bottom surface of the turntable, thereby ensuring that the turntable 2 remains in a horizontal state when encountering large waves during non-construction of the ship, effectively preventing damage to the turntable 2 during non-construction.

[0042] The asymmetrical layout of the top brake mechanism 1 utilizes the fact that the waves are larger on both sides of the bow and smaller in front and behind the hull during navigation, thus minimizing the number of top brake mechanisms 1 and achieving the effect of correcting the turntable 2 and maintaining its horizontal operation.

[0043] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
