Description

Technical Field

[0001] This utility model relates to the field of scientific research vessel technology, specifically to a mobile equipment platform based on a catamaran scientific research vessel. Background Technology

[0002] Research vessels, also known as scientific research vessels, are ships specifically designed for investigating and researching marine hydrology, geology, meteorology, biology, and other special tasks. They are not only platforms for marine scientific research but also important equipment for developing the ocean, utilizing marine resources, and building a maritime power. Catamaran research vessels adopt a parallel catamaran structure design, with the two hull structures forming a large-span central gap area through a rigid connecting frame, which improves the stability of the vessel and the deck working area, making them suitable for carrying large seabed exploration equipment and multidisciplinary collaborative operations.

[0003] Currently, the central gap area of ​​existing catamaran research vessels is empty. Seabed exploration equipment is lowered into the water directly through the deck inlet by a crane on the deck. When the equipment passes through the inlet, it is easy to collide with the structure and cause damage to the equipment. At the same time, it is inconvenient for researchers to observe the equipment entering the water at close range. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile equipment platform based on a catamaran research vessel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The equipment mobile platform based on the catamaran research vessel includes the catamaran research vessel body. Two symmetrically arranged fixed side frames are fixedly connected between the two hull structures of the catamaran research vessel body. Two parallel I-shaped rails are fixedly connected between the two fixed side frames. A platform body for placing the catamaran research vessel equipment is provided above the two I-shaped rails. Two sets of symmetrically arranged moving mechanisms are fixedly connected to the four corners of the bottom of the platform body. The two moving mechanisms located on the same side are respectively connected to the two I-shaped rails.

[0007] The moving mechanism includes an L-shaped frame fixedly connected to the bottom of the platform body. A housing is fixedly connected to one lateral end of the L-shaped frame. A locking drive mechanism is fixedly connected to one side of the housing. One end of the locking drive mechanism passes through the housing and is fixedly connected to a first gear. Two rotating shafts are inserted and rotatably connected to the side of the housing away from the locking drive mechanism. Two meshing second gears are fixedly connected to the inner ends of the two rotating shafts. The first gear meshes with one of the second gears. Rollers are fixedly connected to the outer ends of the two rotating shafts. The two rollers abut against and roll against the upper and lower inner walls of the I-shaped track, respectively.

[0008] As a further embodiment of this utility model: the locking drive mechanism includes a cover fixed to one side of the housing, a drive motor fixedly connected to one side of the cover, a drive shaft fixedly connected to the drive end of the drive motor, one end of the drive shaft penetrating into the cover and fixedly connected to a worm gear, a rotating rod rotatably connected to the inner wall of the cover via a first bearing component, a worm wheel fixedly connected to the rotating rod and meshing with the worm gear, and one end of the rotating rod penetrating into the housing and fixedly connected to a first gear.

[0009] As a further embodiment of this utility model, the inner wall of the housing is rotatably connected to two rotating shafts via two second bearing components.

[0010] As a further embodiment of this utility model, the diameter of the first gear is less than half the diameter of the second gear.

[0011] As a further embodiment of this utility model, the sidewalls of the two I-shaped tracks are respectively fixedly connected to the two hull structural sidewalls of the catamaran research vessel.

[0012] As a further improvement of this utility model, the two ends of the two fixed side frames are fixedly connected to the two hull structural side walls of the catamaran research vessel body by welding.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the setting of a moving mechanism, an I-shaped track, and a platform, activates a drive motor to rotate a worm gear fixed to the drive shaft. Since the worm gear meshes with a worm wheel, it in turn rotates a first gear fixed to a rotating rod. This first gear meshes with one of the second gears, and the two second gears are also meshed together. At this time, the two second gears rotate simultaneously in opposite directions, thereby driving two rollers fixed to two rotating shafts to rotate in opposite directions. The two rollers then roll along the track groove of the I-shaped track, thus realizing the moving function of the platform. This allows for the movement and transport of equipment from a catamaran research vessel until it is moved to the middle of the vessel's body, facilitating the direct lowering of the equipment underwater by a crane, avoiding collisions. The operation is simple, and it allows researchers to closely observe the equipment's entry into the water. Furthermore, the platform can also serve as a temporary storage point for the equipment, combining storage and transportation functions. Attached Figure Description

[0021] Please see Figures 1-4 In this practical embodiment, the equipment mobile platform based on the catamaran research vessel includes the catamaran research vessel body 1. Two symmetrically arranged fixed side frames 2 are fixedly connected between the two hull structures of the catamaran research vessel body 1. Two parallel I-shaped rails 3 are fixedly connected between the two fixed side frames 2. A platform body 4 for placing the catamaran research vessel equipment is provided above the two I-shaped rails 3. The equipment is hoisted onto the platform body 4 using a shore crane. Two sets of symmetrically arranged moving mechanisms are fixedly connected to the four corners of the bottom of the platform body 4. The two moving mechanisms located on the same side are respectively connected to the two I-shaped rails 3. The motors on the four moving mechanisms are synchronously controlled by a synchronizer. Their power supply terminals can be connected to the power supply terminals on the catamaran research vessel body 1. The circuit involved is existing technology, which can be fully implemented by those skilled in the art and does not need to be elaborated.

[0022] The moving mechanism includes an L-shaped frame 5 fixedly connected to the bottom of the platform body 4. A housing 6 is fixedly connected to one lateral end of the L-shaped frame 5. A locking drive mechanism is fixedly connected to one side of the housing 6. One end of the locking drive mechanism passes through the housing 6 and is fixedly connected to a first gear 7. Two rotating shafts 8 are inserted and rotatably connected to the side of the housing 6 away from the locking drive mechanism. Two meshing second gears 9 are fixedly connected to the inner ends of the two rotating shafts 8. The first gear 7 meshes with one of the second gears 9. Rollers 10 are fixedly connected to the outer ends of the two rotating shafts 8. The upper and lower sides of the I-shaped track 3 are grooved surfaces. The two rollers 10 are respectively pressed against the inner walls of the upper and lower sides of the I-shaped track 3 and are rolled.

[0023] When the locking drive mechanism is working, it can drive the first gear 7 to rotate. Since it meshes with one of the second gears 9, and the two second gears 9 are also meshed and connected, the two second gears 9 rotate in opposite directions at the same time. This drives the two rollers 10, which are fixed to the two rotating shafts 8, to rotate in opposite directions. At this time, the two rollers 10 roll and move along the track groove of the I-shaped track 3, thereby realizing the movement function of the platform body 4. The equipment of the catamaran research vessel can be moved and transported until the equipment is moved and transported to the middle of the catamaran research vessel body 1 for water tank detection. This device uses the movable platform body 4 to move and transport the equipment on the catamaran research vessel body 1. Compared with using only a crane for transportation, it is more convenient to use and safer.

[0024] like Figure 3 and Figure 4 As shown: The locking drive mechanism includes a cover 11 fixed to one side of the housing 6. A drive motor 12 is fixedly connected to one side of the cover 11. A drive shaft 13 is fixedly connected to the drive end of the drive motor 12. One end of the drive shaft 13 passes through the cover 11 and is fixedly connected to a worm gear 14. A rotating rod 16 is rotatably connected to the inner wall of the cover 11 through a first bearing 15. A worm wheel 17 that meshes with the worm gear 14 is fixedly connected to the rotating rod 16. One end of the rotating rod 16 passes through the housing 6 and is fixedly connected to a first gear 7. When the drive motor 12 works, it can drive the worm gear 14 fixed to the drive shaft 13 to rotate. Since the worm gear 14 meshes with the worm wheel 17, it can drive the first gear 7 fixed to the rotating rod 16 to rotate. This structure utilizes the principle of irreversible worm gear to make the rolling of the roller 10 have an automatic locking function to prevent deviation.

[0025] like Figure 4 As shown: The inner wall of the housing 6 is rotatably connected to the two rotating shafts 8 through two second bearing components 18, making the rotation of the rotating shafts 8 more stable.

[0026] like Figure 4 As shown: the diameter of the first gear 7 is less than half the diameter of the second gear 9. The smaller gear drives the larger gear to rotate, which requires less effort.

[0027] like Figure 1 As shown: the side walls of the two I-shaped tracks 3 are fixedly connected to the two hull structure side walls of the catamaran research vessel body 1, making the structure more stable.

[0028] like Figure 1 As shown: the two ends of the two fixed side frames 2 are fixedly connected to the two hull structure side walls of the catamaran research vessel body 1 by welding, and the connection is reliable.

[0029] Preferably, the platform body 4 is composed of a square tube frame and a top plate, and a detachable railing can be installed on the upper side edge of the platform body 4 to ensure the safety of researchers working on the platform body.

[0030] Working principle: When in use, the equipment is hoisted onto the platform body 4 by a shore crane. When the drive motor 12 is started, it can drive the worm 14 fixed to the drive shaft 13 to rotate. Since the worm 14 meshes with the worm wheel 17, it can drive the first gear 7 fixed to the rotating rod 16 to rotate. This structure utilizes the principle of irreversible worm gear to make the rolling of the roller 10 have an automatic locking function to prevent deviation.

[0031] When the first gear 7 is driven to rotate, it meshes with one of the second gears 9, and the two second gears 9 are also meshed together. At this time, the two second gears 9 rotate in opposite directions simultaneously, which in turn drives the two rollers 10 fixed to the two rotating shafts 8 to rotate in opposite directions. At this time, the two rollers 10 roll along the track groove of the I-shaped track 3, thereby realizing the movement function of the platform body 4. The equipment of the catamaran research vessel can be moved and transported until the equipment is moved and transported to the middle of the catamaran research vessel body 1, so that the crane can directly lower the equipment into the water, avoiding collisions. The operation is simple, and it is also convenient for researchers to observe the equipment entering the water at close range. In addition, the platform body 4 can also serve as a temporary storage point for the equipment, combining the functions of storing and transporting equipment.
