[0033] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] This invention provides a specific embodiment of an inclined material conveying device for ships, such as... Figure 1 As shown, the device includes a first support rod 10, a second support rod 20, a first guide rail 30, a second guide rail 40, a cargo bin 50, and a pneumatic rod 60. The first support rod 10 is installed at the top of the gangway handrail; the second support rod 20 is installed at the bottom of the gangway handrail; one end of the first guide rail 30 is located on one side of the first support rod 10, and the other end of the first guide rail 30 is located on one side of the second support rod 20; one end of the second guide rail 40 is located on the other side of the first support rod 10, and the other end of the second guide rail 40 is located on the other side of the second support rod 20; one end of the cargo bin 50 is movably mounted on the first guide rail 30, and the other end is movably mounted on the second guide rail 40; one end of the pneumatic rod 60 is mounted on the second support rod 20, and the other end is connected to the cargo bin 50, for driving the cargo bin 50 to move along the first guide rail 30 and the second guide rail 40.

[0036] Ships are typically equipped with gangways for easy access from lower to upper decks. When needed, the inclined cargo conveyor system can be secured to the gangway handrail by mounting the first support rod 10 and the second support rod 20. The cargo bin 50 is used to hold cargo, and the extension and retraction of the pneumatic rod 60 moves the cargo bin 50 along the first guide rail 30 and the second guide rail 40, thus facilitating cargo transport. The inclined cargo conveyor system is mounted on the gangway handrail, saving space on the ship.

[0037] The pneumatic rod 60 in this embodiment is an existing pneumatic rod structure. The working principle of the pneumatic rod 60 is as follows: the pneumatic rod 60 is filled with pure high-pressure nitrogen gas and has a vent hole inside. The gas pressure at both ends of the piston is equal, and the cross-sectional areas on both sides of the piston are different. One end has a piston rod, and the other end does not have a piston rod. Under the action of air pressure, pressure is generated towards the side with the smaller cross-sectional area, thereby realizing the vertical extension and retraction of the pneumatic rod 60.

[0038] The air pressure rod 60 can be extended and retracted manually. A control lever 61 can be arranged on the air pressure rod 60. The control lever 61 can be shaken to extend and retract the air pressure rod 60, thereby saving manpower. The air pressure rod 60 does not need to be driven by additional power, thereby saving the limited power resource on the ship. In addition, the inclined material conveying device is convenient to install and use. Any person can operate the inclined material conveying device without professional operation. The inclined material conveying device can prevent the danger of falling from the gangway when soldiers carry materials with both hands. The soldiers' hands are greatly liberated, and the efficiency of carrying the materials is improved.

[0039] Preferably, as shown in the drawings, the inclined material conveying device further comprises a buffer mechanism 70. The lower ends of the first guide rail 30 and the second guide rail 40 are respectively provided with the buffer mechanism 70. When the air pressure rod 60 fails and the hopper 50 freely falls at a high speed, the buffer mechanism 70 can play a buffering role. The buffer mechanism 70 can be an elastic member such as a spring. Figure 1 Preferably, as shown in the drawings, the buffer mechanism 70 comprises a first threaded sleeve 71, a gasket 72, a second threaded sleeve 73, a spring 74, and a steel sheet 75. The first threaded sleeve 71 and the second threaded sleeve 73 are arranged in the length direction of the first guide rail 30 and are respectively threadedly connected with the first guide rail 30. The first threaded sleeve 71 and the second threaded sleeve 73 have the same thread direction and opposite tightening directions. The gasket 72 is arranged between the first threaded sleeve 71 and the second threaded sleeve 73. The spring 74 is arranged at one end of the first threaded sleeve 71 close to the hopper 50. The steel sheet 75 is arranged at the other end of the spring 74 away from the first threaded sleeve 71.

[0040] Figure 1 When installed, the first threaded sleeve 71 and the second threaded sleeve 73 are screwed on the first guide rail 30, and then the first threaded sleeve 71 and the second threaded sleeve 73 are tightened in opposite directions. The first threaded sleeve 71 and the second threaded sleeve 73 generate a friction force of mutual extrusion. The first threaded sleeve 71 and the second threaded sleeve 73 are provided with a rubber gasket with a rough surface, thereby increasing the friction force and achieving the effect of fastening the two threaded sleeves at one position.

[0041] The first threaded sleeve 71 is arranged above the second threaded sleeve 73. The spring 74 is arranged above the first threaded sleeve 71. The steel sheet 75 is arranged above the spring 74. When the hopper 50 is slightly impacted, the spring 74 can effectively rebound. When the air pressure rod 60 fails due to overweight of the materials, i.e., the hopper 50 freely falls, the double-threaded work-shaped threaded sleeve can effectively block the impact generated by the sliding of the hopper 50. The buffer mechanism 70 arranged on the second guide rail 40 has the same structure as the buffer mechanism 70 arranged on the first guide rail 30.

[0042] The first threaded sleeve 71 is arranged above the second threaded sleeve 73. The spring 74 is arranged above the first threaded sleeve 71. The steel sheet 75 is arranged above the spring 74. When the hopper 50 is slightly impacted, the spring 74 can effectively rebound. When the air pressure rod 60 fails due to overweight of the materials, i.e., the hopper 50 freely falls, the double-threaded work-shaped threaded sleeve can effectively block the impact generated by the sliding of the hopper 50. The buffer mechanism 70 arranged on the second guide rail 40 has the same structure as the buffer mechanism 70 arranged on the first guide rail 30.

[0043] ​Preferably, such as Figure 2 As shown, the upper ends of the first guide rail 30 and the second guide rail 40 are respectively provided with buffer mechanisms 70. The buffer mechanisms 70 provided at the upper ends of the first guide rail 30 and the second guide rail 40 can play a buffering role when the pneumatic rod 60 fails and pops upward, so as to avoid injury to personnel.

[0044] Preferably, the inclined material conveying device further includes multiple limiting mechanisms 80. One end of the second support rod 20 is connected to the first guide rail 30 through one limiting mechanism 80, and the other end of the second support rod 20 is connected to the second guide rail 40 through another limiting mechanism 80. The first support rod 10 and the second support rod 20 are respectively connected to the first guide rail 30 and the second guide rail 40 through the limiting mechanisms 80. In addition, the limiting mechanism 80 is located below the buffer mechanism 70. When the buffer mechanism 70 fails, the limiting mechanism 80 can further prevent the impact caused by the slippage of the hopper 50.

[0045] The limiting mechanism 80 includes a third threaded sleeve 81 and a fourth threaded sleeve 82, which are arranged vertically along the length of the first guide rail 30 and are threadedly connected to the first guide rail 30 respectively. The threads of the third threaded sleeve 81 and the fourth threaded sleeve 82 are in the same direction but opposite in tightening direction. The second support rod 20 is disposed between the third threaded sleeve 81 and the fourth threaded sleeve 82. The installation method of the third threaded sleeve 81 and the fourth threaded sleeve 82 is the same as that of the first threaded sleeve 71 and the second threaded sleeve 73. Using this method to fasten the first support rod 10 and the second support rod 20 is not only convenient for disassembly and assembly and easy for replacement, but also has a simple structure, low cost, and does not require special personnel for maintenance.

[0046] Preferably, the inclined material conveying device further includes a weight sensor 90, which is installed at the bottom of the hopper 50. With the weight sensor 90 installed inside the hopper 50, when the weight of the materials inside the hopper 50 reaches its limit, the weight sensor 90 will issue a warning signal to prevent overloading and improve the safety of the inclined conveying device.

[0047] The inclined material conveying device also includes a support base 100, which is mounted on the second support rod 20. The bottom of the pneumatic rod 60 is fixed to the support base 100. The pneumatic rod 60 can be welded to the support base 100 to improve the connection stability between the pneumatic rod 60 and the support base 100.

[0048] The inclined material conveying device of this embodiment has the following technical advantages:

[0049] (1) It has a simple structure, is economical and practical, and does not require additional electric drive, thus saving the ship's power resources;

[0050] (2) installation and use method is simple, maintenance is simple, anyone can operate, does not occupy extra installation space, only needs to depend on the gangway handrail installation;

[0051] (3) Eliminate the risk of falling accidents that may occur when soldiers carry materials up and down the suspended ladder with both hands;

[0052] (4) greatly liberate the hands of soldiers carrying supplies, improve the efficiency of carrying supplies;

[0053] (5) strong flexibility, the number of corresponding installations can be increased or decreased according to the amount of goods;

[0054] (6) by two reverse tightening of the nut, the nut is fastened in a position, and then the spring and steel sheet are fixed, so that the buffer mechanism is simple in structure, convenient to replace, low in cost, and the buffer mechanism has good buffering effect, slight impact of the hopper, spring elasticity can effectively rebound, if overweight causes hydraulic rod failure, that is, the hopper freely falls, the double-threaded I-beam bolt can effectively block the impact generated by the sliding of the hopper;

[0055] (7) by setting the weight sensor, overloading can be avoided to avoid danger.

[0056] The above only describes the preferred embodiments of the present application, and it should be noted that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
