Description

Technical Field

[0001] The utility model relates to the field of marine hull sway testing, in particular to a marine wave compensation platform. Background Art

[0002] The swaying of the ship's hull at sea can cause instability in the equipment installed on the ship. If the connection between the equipment and the hull is not tight, the equipment may topple over with the swaying of the hull, causing an accident.

[0003] Compensation parts such as oil cylinders and electric cylinders in existing wave compensation devices need to take into account both compensation and load-bearing, which can easily affect the compensation accuracy and compensation effect. Summary of the invention

[0004] In view of the shortcomings of the prior art, the utility model provides a marine wave compensation platform, which adopts a combination of air cylinder and electric cylinder to ensure both weighing effect and compensation accuracy, and simplifies the structure to adapt to harsh working conditions. The technical solution adopted by the utility model is:

[0005] A ship wave compensation platform comprises a lower platform, an upper platform, a posture sensor, a cylinder and an electric cylinder. The posture sensor is arranged on the lower platform and is used to feed back the swing angle of the lower platform. The two ends of the cylinder are respectively hinged to the center of the lower platform and the center of the upper platform. There are multiple electric cylinders arranged equidistantly around the cylinder, and the two ends of any electric cylinder are respectively hinged to the lower platform and the upper platform.

[0006] Furthermore, the bottom of the cylinder is hinged to the lower platform via a first universal ball bearing, and the top of the cylinder is hinged to the upper platform via a second universal ball bearing.

[0007] Furthermore, the bottom of the electric cylinder is hinged to the lower platform via a first hinge support.

[0008] Furthermore, a plurality of bearing seats are evenly arranged on the lower surface of the upper platform, and a plurality of the bearing seats are rotatably connected to shaft rods, the shaft rods extend radially along the upper platform, and one end of the plurality of the shaft rods is hinged to the output ends of the plurality of the electric cylinders.

[0009] Furthermore, four wire troughs are arranged on the lower platform, and the four wire troughs form a rectangular wire rack. The cylinder is located at the center of the rectangular wire rack, and a control system is arranged inside the wire rack.

[0010] Advantages of the utility model:

[0011] The center uses cylinders as the load-bearing parts of the upper platform, and matches them with peripheral electric cylinders as wave compensation parts, which not only ensures the strength of the upper platform, but also realizes the wave compensation of the upper platform. Equipment of different weights can be matched with cylinders of different specifications;

[0012] Since the electric cylinder does not participate in the load-bearing, the wear rate and power loss of the electric cylinder are reduced, and the compensation accuracy is improved;

[0013] Since the entire heave compensation platform does not use oil circuits, it is convenient for maintenance and can adapt to harsh working conditions;

[0014] The electric cylinder is driven by a motor to accurately calculate the output stroke, reduce the use of intermediate linkage parts, reduce power loss, and efficiently use energy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Please refer to the attached Figure 1-Figure 3 The utility model provides a ship wave compensation platform, including a lower platform 101, an upper platform 102, a posture sensor 103, a cylinder 104, and an electric cylinder 105. The posture sensor 103 is arranged on the lower platform 101 and is used to feed back the swing angle of the lower platform 101. The two ends of the cylinder 104 are respectively hinged to the center of the lower platform 101 and the center of the upper platform 102. There are multiple electric cylinders 105, and the multiple electric cylinders 105 are equidistantly arranged around the cylinder 104. The two ends of any electric cylinder 105 are respectively hinged to the lower platform 101 and the upper platform 102.

[0021] The attitude sensor 103, the air cylinder 104 and the electric cylinder 105 of the present application are respectively connected to the controller of the control system 107. The lower platform is installed on the hull, and the swing signal of the hull is transmitted to the controller through the attitude sensor 103. The controller controls the travel distance of the electric cylinder 105 to keep the upper platform 102 in a horizontal state, thereby achieving the purpose of wave compensation. The entire compensation platform is oil-free, which is not only clean and tidy, but also has an accurate compensation distance, reduces the use of intermediate linkage parts, reduces power loss, and efficiently uses energy.

[0022] It should be noted that, in the present application, the lower platform 101 and the upper platform 102 are both disc-shaped. Since the cylinder 104, as an important load-bearing component, needs to be arranged at the center of the first lower platform 101 and the upper platform 102, the disc-shaped structure of the lower platform 101 and the upper platform 102 can find the center point more quickly, which facilitates the arrangement of the cylinder 104. The center uses the cylinder 104 as the load-bearing component of the upper platform, and the surrounding electric cylinder 105 as a wave compensation component, which not only ensures the strength of the upper platform, but also realizes the wave compensation of the upper platform. Equipment of different weights can be matched with cylinders of different specifications.

[0023] In a specific embodiment, as shown in the attached Figure 1 As shown, the circular area of ​​the upper platform 102 is smaller than the circular area of ​​the lower platform 101, and the two ends of the electric cylinder 105 are respectively connected to the edge of the lower platform 101 and the edge of the upper platform 102; the three electric cylinders 105 can adjust the upper platform 102 in three directions to improve the accuracy of wave compensation.

[0024] Please refer to the attached Figure 2 and attached Figure 3 In order to facilitate the rotation connection of the cylinder 104 and avoid the torque between the cylinder 104 and the upper and lower platforms, the bottom of the cylinder 104 is hinged to the lower platform 101 through a first universal ball bearing 1041, and the top of the cylinder 104 is hinged to the upper platform 102 through a second universal ball bearing 1042.

[0025] Please refer to the attached Figure 2 and attached Figure 3 In order to facilitate the rotational connection of the electric cylinder 105, the bottom of the electric cylinder 105 is hinged to the lower platform 101 through a first hinge support 1051; a plurality of bearing seats 1052 are evenly arranged on the lower surface of the upper platform 102, and a plurality of the bearing seats 1052 are rotatably connected to shaft rods 1053, which extend radially along the upper platform 102, and one end of a plurality of the shaft rods 1053 is hinged to the output ends of a plurality of the electric cylinders 105.

[0026] It should be noted that the bearing seat 1052 is fixed on the upper platform 102, and the shaft rod 1053 is arranged horizontally, with the two ends respectively connected to the bearing seat 1052 and the telescopic rod of the electric cylinder 105. At the same time, the telescopic rod of the electric cylinder 105 is rotatably connected to the shaft rod 1053 through a pin; due to the cooperation between the bearing seat 1052 and the shaft rod 1053, the electric cylinder 105 not only has the ability to drive the bearing seat 1052 to rise and fall, but also has the ability to drive the bearing rod 1053 to rotate around its own axis, thereby preventing the telescopic rod of the electric cylinder 105 from being bent and deformed by force when the upper platform 102 shakes.

[0027] Please refer to the attached Figure 2 and attached Figure 3 The lower platform 101 is provided with four wire troughs 106, which enclose a rectangular wire rack, the cylinder 104 is located at the center of the rectangular wire rack, and the wire rack is provided with a control system 107. The wire troughs 106 make the wiring of each control element in the control system 107 more convenient and neat, and can also balance the center of gravity of the lower platform 101.

[0028] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
