[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

Link component 4 connects two adjacent long baffles 2 and two adjacent short baffles 3. The lifting control assembly 5 is connected to two connecting assemblies 4 at adjacent ends of the long baffle 2 and the short baffle 3. The lifting control assembly 5 is connected to the top of the vehicle platform 1 and is used to control the lifting of the long baffle 2 and the short baffle 3. Synchronous control component 6, the bottom end of the lifting control component 5 is respectively connected to the synchronous control component 6 in a transmission manner, the synchronous control component 6 is connected to the bottom of the vehicle plate 1, and the synchronous control component 6 is used to control the operation of the lifting control component 5; The movable component 7 is installed at the bottom of the vehicle platform 1 and is used to move the fabric cart.

[0041] In this technical solution, long baffles 2 and short baffles 3 are used to block and protect the material on the fabric placing vehicle, preventing the material from falling out when the fabric placing vehicle moves with the ship, so as to facilitate the movement of the fabric placing vehicle on the ship. At the same time, a single synchronous control component 6 can control the operation of multiple lifting control components 5, thereby driving multiple long baffles 2 and short baffles 3 to operate simultaneously. This makes the height adjustment of long baffles 2 and short baffles 3 easier, and the height of long baffles 2 and short baffles 3 is adjustable, so that the fabric placing vehicle can adapt to materials of different heights and facilitates the loading and unloading of materials with larger weights, making the loading and unloading of the fabric placing vehicle more labor-saving.

[0042] The linking component 4 includes a fixed frame 41, the bottom of which is connected to the top of the vehicle plate 1. Both ends of the long baffle 2 and the short baffle 3 are connected to follower strips 43. One end of the follower strip 43 is connected to one side of the mounting plate 42. The mounting plate 42 is slidably disposed in the inner cavity of the fixed frame 41. Two symmetrically distributed flexible connecting chains 44 connect two adjacent mounting plates 42, and the bottom of the lowermost mounting plate 42 is connected to the flexible connecting chain 44, the bottom end of which is connected to the inner wall of the bottom surface of the fixed frame 41.

[0043] In this technical solution, the connecting component 4 enables adjacent long baffles 2 and adjacent short baffles 3 to be connected sequentially, so that multiple long baffles 2 and multiple short baffles 3 can be folded and unfolded according to height.

[0044] A flexible separator 45 is provided between two flexible connecting chains 44 on the same horizontal plane, and the two ends of the flexible separator 45 are respectively connected to two mounting plates 42; The bottom end of the flexible partition strip 45 located at the bottom is connected to the bottom of the inner cavity of the fixed frame 41.

[0045] In this technical solution, the two flexible connecting chains 44 can be separated by the flexible separator 45, so as to avoid the two flexible connecting chains 44 from getting tangled and affecting subsequent use.

[0046] The lifting control component 5 includes a mounting frame 51. Four mounting frames 51 arranged in a rectangular structure are connected to the top of the vehicle plate 1. A lifting threaded shaft 52 is provided in the inner cavity of the mounting frame 51. The bottom end of the lifting threaded shaft 52 is connected to the synchronous control component 6 for transmission. The lifting threaded shaft 52 is threadedly connected to a lifting plate 53, and a plurality of lifting columns 54 are connected to the top of the lifting plate 53. The surface of the lifting column 54 is slidably connected through to the top surface of the mounting frame 51. The top of the lifting column 54 is connected to the bottom of the control plate 55, and the sides of the control plate 55 are respectively connected to the two mounting plates 42 located at the top.

[0047] In this technical solution, the height of the long baffle 2 and the short baffle 3 can be adjusted using the lifting control component 5.

[0048] In use, the synchronous control component 6 simultaneously controls the rotation of the four lifting threaded shafts 52. When the lifting threaded shafts 52 rotate, they drive the corresponding lifting plates 53 to move, which in turn drives the corresponding lifting columns 54 to move in the same direction, thereby driving the corresponding control plates 55 to move in the same direction, so that the four control plates 55 can move in the same direction at the same time. When the control plate 55 moves, it drives the uppermost long baffle 2 and short baffle 3 to move. When the long baffle 2 and short baffle 3 move upward, they drive one end of the flexible connecting chain 44 and the flexible separating strip 45 to move, and cause the flexible connecting chain 44 and the flexible separating strip 45 to unfold. Then, it drives the other long baffle 2 and short baffle 3 to move upward in sequence, unfolding multiple long baffle 2 and short baffle 3 in sequence. When the long baffle 2 and the short baffle 3 move downward, the flexible partition 45 contracts under the action of gravity, so that the multiple long baffles 2 and short baffles 3 are successively stored in the fixed frame 41, thus completing the storage of the long baffles 2 and short baffles 3.

[0049] The synchronization control component 6 includes a protective housing 61, the top of which is connected to the bottom of the vehicle panel 1; The protective housing 61 has four rectangular transmission sprockets 62 arranged in the inner cavity, and the four transmission sprockets 62 are respectively connected to the surfaces of four lifting threaded shafts 52. The transmission sprocket 62 is engaged with a transmission chain 63 on its side, and the four transmission sprockets 62 are connected by the transmission chain 63.

[0050] In this technical solution, multiple lifting control components 5 can be controlled simultaneously by the synchronous control component 6.

[0051] The bottom surfaces of the vehicle plate 1 and the mounting frame 51 are provided with multiple mounting holes. The bottom end of the lifting threaded shaft 52 is rotatably connected to the mounting frame 51 and the vehicle plate 1, respectively, and the bottom end of the lifting threaded shaft 52 is rotatably connected to the inner wall of the bottom surface of the protective shell 61.

[0052] In this technical solution, the rotation of the lifting threaded shaft 52 can drive the lifting plate 53 to move.

[0053] One of the lifting threaded shafts 52 has a secondary gear 64 connected to its surface. The secondary gear 64 is meshed with a main gear 65 on its side. The main gear 65 is connected to the output end of the control power source 66. The control power source 66 is connected to the bottom surface of the protective housing 61.

[0054] In this technical solution, the rotation of the main gear 65 can be driven by controlling the power source 66.

[0055] In use, the main gear 65 is driven to rotate by the control power source 66, which in turn drives the secondary gear 64 to rotate, which in turn drives the corresponding transmission sprocket 62 to rotate, thereby driving the transmission chain 63 to rotate, which in turn drives the other transmission sprockets 62 to rotate, so that the four transmission sprockets 62 can rotate simultaneously. When the four transmission sprockets 62 rotate simultaneously, they can drive the four lifting threaded shafts 52 to rotate simultaneously.

[0056] The moving component 7 includes a rotating connecting shaft 71. Two symmetrically distributed rotating connecting shafts 71 are provided below the vehicle plate 1. The surfaces of the rotating connecting shafts 71 are rotatably connected to two supporting side plates 72 respectively. The two supporting side plates 72 are symmetrically distributed, and the top of the supporting side plates 72 is connected to the bottom of the vehicle plate 1. Both ends of the rotary connecting shaft 71 are connected to movable wheels 73.

[0057] In this technical solution, the movable component 7 facilitates the movement of the fabric cart.

[0058] When in use, the fabric cart can be moved by rotating the movable wheel 73.

[0059] Example 2 As one embodiment of this application, such as Figures 7 to 9 As shown, the difference between it and Embodiment 1 is that the two rotating connecting shafts 71 are connected by a locking assembly 8, which includes a rotating gear 81, and the rotating gear 81 is connected to the center of each of the two rotating connecting shafts 71. A locking rack 82 is provided on one side of the rotating gear 81, and the rotating gear 81 and the locking rack 82 engage when they are in contact. One end of the locking rack 82 is connected to one side of the movable mounting frame 83, one side of the movable mounting frame 83 is threaded to the surface of the bidirectional threaded shaft 84, and the middle part of the bidirectional threaded shaft 84 is connected to the power component 9 for transmission. The bottom of the vehicle plate 1 is connected to four fixed side plates 85. The two fixed side plates 85 located at the edge are rotatably connected to both ends of the bidirectional threaded shaft 84, and the two fixed side plates 85 located on the inner side are rotatably connected to the surface of the bidirectional threaded shaft 84. The two fixed side plates 85 located at the edge are set inside the movable mounting frame 83.

[0060] Multiple positioning rails 86 are connected between the two fixed side plates 85 and the fixed outer shell 91 located at the edge, and the positioning rails 86 are slidably connected through one side of the movable mounting frame 83.

[0061] In use, the movable mounting frame 83 moves along the positioning track 86. The positioning track 86 limits the movement trajectory of the movable mounting frame 83, making the movement of the movable mounting frame 83 more stable and smooth.

[0062] In this technical solution, the moving part 7 can be locked by the locking component 8, which increases the stability of the fabric carriage when it stops.

[0063] The power component 9 includes a fixed housing 91, which is connected to the bottom of the vehicle plate 1, and the two sides of the fixed housing 91 are respectively rotatably connected to the surface of the bidirectional threaded shaft 84. The inner wall of the fixed housing 91 is connected to a drive source 92. The output end of the drive source 92 is connected to a first gear 93. The side of the first gear 93 is meshed with a second gear 94. The second gear 94 is connected to the surface of the bidirectional threaded shaft 84.

[0064] In this technical solution, the power component 9 can provide driving force for the operation of the locking assembly 8.

[0065] When the fabric carrier is loading or unloading materials or when the ship is rocking, the drive source 92 drives the first gear 93 to rotate, which in turn drives the second gear 94 to rotate, which in turn drives the bidirectional threaded shaft 84 to rotate. When the bidirectional threaded shaft 84 rotates, it drives the movable mounting frames 83 on both sides to move in opposite directions along the positioning track 86, which in turn drives the locking rack 82 to move in the same direction, so that the locking rack 82 and the rotating gear 81 are engaged, thereby locking the rotating connecting shaft 71 and the moving wheel 73 and increasing the stability of the fabric carrier. When it is necessary to move the fabric carriage, the locking rack 82 is moved away from the rotating gear 81 by using the opposite method. At this time, the locking of the moving wheel 73 and other structures can be released, which makes it easier to move the fabric carriage.

[0066] The control power source 66 and drive source 92 are motor sets or other devices that can output rotational kinetic energy.

[0067] The flexible connecting chain 44 is a chain or other rope-like structure with a certain mass.
