Description
Technical Field
[0001] The utility model relates to the technical field of floating docks, and particularly relates to a new type of airbag floating dock. Background Art
[0002] During the manufacturing, testing and maintenance processes of ships, it is often necessary to move the ship from land to water or from water to land. Since the volume and length of the ship are relatively large, it is difficult to move. Therefore, at present, the movement of the hull is often achieved through a lifting device or a floating dock with a mobile trailer.
[0003] Due to the complex structure, high cost and difficult maintenance of the lifting device, it is more cost-effective to use a floating dock with a mobile trailer for the land-water transfer of inland river ships. The main method of using a floating dock with a mobile trailer for the land-water transfer of inland river ships is as follows: place the mobile trailer in the floating dock for fixation, and the floating dock sinks as a whole underwater by filling with water. The inland river ship sails into the area above the floating dock; after the ship is stabilized on the mobile trailer, the floating dock is raised by draining water to lift the inland river ship out of the water, and then the mobile trailer is pulled to achieve the movement of the inland river ship.
[0004] However, due to the shallow water depth of the inland river channel, the molded depth of the existing ordinary floating dock is at least 1.8 m. Even when the ordinary floating dock touches the bottom after draining water, it is difficult to sink to the depth at which the inland river ship can drive into the floating dock; at the same time, the river bottom of the inland river is prone to siltation soon after excavation. Therefore, the problem of difficult maintenance and launching of inland river ships cannot be fundamentally solved by excavating the river bottom.
[0005] Therefore, in view of the characteristics of the shallow water depth of the inland river channel, it is very necessary to design a new type of floating dock in this field. Content of the Utility Model
[0006] The purpose of the utility model is to overcome the defects of the prior art and provide a new type of airbag floating dock.
[0007] To achieve the above purpose and other purposes, the utility model is realized by including the following technical solutions: The utility model provides a new type of airbag floating dock, which includes a frame body; a plurality of airbags fixedly arranged on the lower end surface of the frame body and communicated with an air charging and discharging device arranged on land through an air charging and discharging pipe; and the plurality of airbags are arranged at equal intervals in a direction parallel to the width direction of the frame body.
[0008] In one embodiment, the airbag is communicated with an air charging and discharging device arranged on land through an air charging and discharging pipe.
[0009] In one embodiment, the air charging and discharging pipe is a hose or a telescopic pipe with tensile strength.
[0010] In one embodiment, the length of the airbag is greater than or equal to the width of the frame body.
[0011] In one embodiment, the two ends of the airbag respectively extend beyond the length of the frame body by 0.5 m to 1 m.
[0012] In one embodiment, the trailer includes a vehicle frame and wheels. The wheels are fixedly arranged at the bottom of the vehicle frame through roller shafts; the wheels are slidably mounted on the trailer track through rollers.
[0013] In one embodiment, the roller is a track wheel with grooves provided on its axial surface and is sleeved on the roller shaft through a bearing; a sealing pressing plate and a retaining ring are also sleeved on the roller shaft. The retaining ring is located outside the sealing pressing plate and presses the sealing pressing plate, so as to form a sealing cavity between the sealing pressing plate, the roller shaft, the bearing and the inner ring of the roller.
[0014] In one embodiment, a cushion block is arranged on the upper end surface of the vehicle frame.
[0015] In one embodiment, a plurality of docking platforms are arranged on the upper end surface of the frame body for fixing a ship; the plurality of docking platforms are symmetrically arranged on both sides of the upper end surface of the frame body along the length direction of the frame body.

And the "connection" mentioned in the present invention, unless otherwise specified, includes both direct and indirect connections.
[0033] In order to avoid confusion with the present utility model, some well-known technical features in the art are not described.
[0034] As Figure 1 and Figure 2 shown, the present utility model provides a new type of airbag floating dock 100, which includes a frame main body 110 and airbags 120. A plurality of the airbags 120 are fixedly arranged on the lower end surface of the frame main body 110 and are arranged at equal intervals in the width direction parallel to the frame main body 110. The distance between adjacent two of the airbags 120 is not less than the radius size of the airbag 120 when it is filled with gas. The airbag 120 is communicated with an air charging and discharging device 300 arranged on land through an air charging and discharging pipe 121. Although Figure 2 the air charging and discharging pipe 121 shown in
[0035] The utility model can deflate the airbag 120 through the air charging and discharging device 300 on land, so that the frame body 110 and the trailer 130 sink to underwater as a whole, so that the ship 200 can drive into the upper part of the new airbag type floating dock 100; after the ship 200 stops stably on the trailer 130, the air charging and discharging device 300 inflates the airbag 120 to increase the buoyancy of the new airbag type floating dock 100 to achieve elevation, so as to lift the ship 200 out of the water surface, and then pull the trailer 130 to realize the land and water movement of the ship 200. Due to the huge compression ratio and large buoyancy of the airbag 120, the frame body 110 can be evenly stressed, and it can adapt to different river channels and hull conditions, and can solve the problems of inland ship maintenance and difficult launching.
[0036] Further, in order to ensure the effectiveness and stability of the floating and sinking of the new airbag type floating dock 100, the length of the airbag 120 is designed to be close to the width of the frame body 110, that is, slightly greater than or equal to the width of the frame body 110. Through testing, when the two ends of the airbag 120 respectively exceed the length of the frame body 110 by 0.5 m to 1 m, the best sinking and floating effects can be obtained.
[0037] Specifically, a dock platform 112 and a fixing member 113 are further arranged on the frame body 110. The ship 200 can be fixed on the dock platform 112 through a cable, so as to realize the fixation of the ship 200 on the frame body 110. A plurality of the dock platforms 112 are symmetrically arranged on both sides of the upper end surface of the frame body 110 along the length direction of the frame body 110. As Figure 1 shown, the dock platforms 112 on the same side can be symmetrically arranged with the center of the frame body 110 as the axis, or can be arranged at equal intervals not shown in the figure, as long as the ship 200 is fixed symmetrically left and right, front and back. The fixing member 113 is arranged at one end of the frame body 110 and can be an ear plate for passing through a fixing cable on land to realize the relative fixed connection between the new airbag type floating dock 100 and the land.
[0038] Further, in order to facilitate fixing the moving direction of the trailer 130 and at the same time facilitate the movement of the trailer 130, a trailer track 111 parallel to the length direction thereof can be arranged on the upper end surface of the frame body 110. The trailer track 111 is used to place the trailer 130, and the trailer 130 is used to support and horizontally move the ship 200.
[0039] Please combine Figure 3, the trailer 130 includes a frame 131 and wheels 132. The wheels 132 are fixedly arranged at the bottom of the frame 131 through roller shafts 1322; the wheels 132 are slidably mounted on the trailer track 111 through rollers 1321. Towing rings 134 are further arranged on the front and rear sides of the frame 131 for threading a rope to apply a pulling force to the frame 131 to pull the trailer 130 to move.
[0040] Further, in order to prevent the paint surface of the ship 200 from being scratched by the metal frame 131, a cushion block 133 can be arranged on the upper end surface of the frame 131. The cushion block 133 has a certain rigidity and elasticity and can be a wooden block or a rubber block. The number of the cushion blocks 133 can be two as shown in Figure 3 , and they are symmetrically arranged on the upper end surface of the frame 131, but this is not necessary. Only one cushion block 133 can be arranged at the center position of the upper end surface of the frame 131.
[0041] Further, during the water-land transfer process of the ship 200, the trailer 130 needs to be immersed in water for a long time. Since water has a certain corrosiveness, it will corrode the wheel bearings of the trailer 130, resulting in poor rotation flexibility of the wheels 130 or even failure. Therefore, waterproof design needs to be carried out on the trailer 130. Please refer to Figure 4 and Figure 5 , in order to ensure that when the trailer 130 is flooded, its bearings do not come into contact with water and are protected from water corrosion, thereby maximizing its service life, the wheel 132 can include a roller 1321, a roller shaft 1322, a bearing 1323, a sealing pressing plate 1324 and a retaining ring 1325. The roller shaft 1322 is fixedly arranged on the frame 131; the roller 1321 is a track wheel with a groove on its axial surface and is sleeved on the roller shaft 1322 through the bearing 1323; the sealing pressing plate 1324 and the retaining ring 1325 are also sleeved on the roller shaft 1322. The retaining ring 1325 is located outside the sealing pressing plate 1324 and presses the sealing pressing plate 1324 so as to form a sealing cavity between the sealing pressing plate 1324 and the inner rings of the roller shaft 1322, the bearing 1323 and the roller 1321. The sealing cavity is used for injecting sealing oil to form an oil seal for the bearing 1323, so as to ensure that when the trailer 130 is flooded, the bearing 1323 does not come into contact with water and is protected from water corrosion, thereby maximizing the service life of the bearing 1323.

The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
