Description

Technical Field

[0001] The present invention relates to a container inner liner bag assembly, a container assembly and a railway transportation system, and belongs to the technical field of railway transportation systems. Background Art

[0002] A container inner liner bag is a large flexible packaging container used to protect bulk goods from contamination, moisture or damage during transportation. It is usually placed inside a standard container and is commonly made of plastics such as polyethylene (PE) and polypropylene (PP). In the structural design of the container inner liner bag, an opening is usually provided at the upper part of the inner liner bag near the door side, and the goods are filled into the container through the top of the container (gravity filling or mechanical filling), and the goods are filled horizontally into the container (conveyor belt or horizontal pneumatic filling). And a discharge port is provided at the bottom for quick unloading (such as a valve or a cutting opening). When the container inner liner bag is used to ship powder materials, the powder materials are filled into the container inner liner bag, and the front, back, left and right of the container inner liner bag are supported by the side wall and the door of the container. However, when unloading, the container door needs to be opened. Due to the loss of the support of the container door, the container inner liner bag is very easy to expand, and even causes the container inner liner bag to burst, and the powder materials pour out instantly, causing personal injuries. The existing solution is to place 5 to 6 square pipes horizontally at the container door to block the inner liner bag, but the square pipes are not easy to install during use, are inconvenient to carry when the vehicle is empty, and are easy to lose. In addition, when the inner liner bag is used for an open-top container, in order to prevent rain and snow from entering the container, an additional tarpaulin needs to be set on the top of the open-top container. Summary of the Invention

[0003] Therefore, the purpose of the present invention is to provide a container inner liner bag assembly integrating the function of a tarpaulin and having relatively high structural strength, and to provide a container assembly and a railway transportation system having the container inner liner bag assembly.

[0004] To achieve the above object, a container inner lining bag assembly of the present invention includes a bag body, a reinforcing cloth, and a reinforcing belt; the reinforcing cloth includes a front cloth piece, a rear cloth piece, and a bottom cloth piece. An accommodation space is formed between the front cloth piece and the rear cloth piece for accommodating the bag body, and the bottom cloth piece is used to support the bag body; the reinforcing belt and the reinforcing cloth are of an integrally fixed connection structure. The reinforcing belt includes a transverse ring body that transversely surrounds the bag body, and the transverse ring body is fixedly connected to the front cloth piece and the rear cloth piece; the transverse ring body includes a top transverse ring body connected to the tops of the front cloth piece and the rear cloth piece and a middle transverse ring body located below the top transverse ring body; the reinforcing belt further includes vertical belts, and the vertical belts are arranged on the left and right sides of the bag body and connect the top transverse ring body, the middle transverse ring body, and the bottom cloth piece; a plurality of first hooks for connecting to an open-top container are arranged on the top transverse ring body; at least one discharge port that can be closed is arranged on the front cloth piece; the bag body includes a bottom surface, side surfaces, and a top surface, and at least one filling port that can be tied is arranged on the top surface; the top surface of the bag body includes a bent portion that can extend to the outside of the left and right sides of the open-top container. The reinforcing belt further includes a plurality of top belts arranged above the bag body. A traction member for connecting to the outer side wall of the container is arranged at the end of the top belt, and the top belt is fixed to the top surface.

[0005] The side surface includes a flanging portion that can be turned outwards to the left and right sides of the container, and the flanging portion is connected to the bent portion.

[0006] A plurality of connecting belts are further arranged on the top transverse ring body, and the connecting belts extend upwards and are fixed to the flanging portion.

[0007] The connecting belt and the top belt clamp the flanging portion and the bent portion therein, and the ends of the connecting belt and the top belt are fixedly connected through the traction member.

[0008] The side surface and the top surface are of a split structure that is hermetically bonded and fixed to each other.

[0009] The top belts located at the front and rear ends of the top surface are respectively provided with eaves portions that can be bent downwards; a plurality of through holes are arranged on each eaves portion for the traction rings on the side wall of the container drainage groove to pass through, and a rope passes through a plurality of the traction rings to prevent the traction rings from coming out of the through holes.

[0010] At least one diagonal tension belt is further arranged on the front cloth piece. An extension section is formed at the end of the diagonal tension belt towards the outside of the front cloth piece, and a second hook for connecting to the container is arranged at the end of the extension section.

[0011] The left and right sides of the front cloth piece are respectively connected with a left bent portion and a right bent portion.

[0012] The present invention further provides a container assembly, including an open-top container and the container inner lining bag assembly as described above.

[0013] The present invention also provides a railway transportation system, including a freight train and the container assembly as described above. The freight train includes a plurality of freight flatcars, and the container assembly is arranged on the freight flatcars.

[0014] Adopting the above technical solutions, the container inner liner bag assembly, the container assembly and the railway transportation system of the present invention have the following beneficial effects compared with the prior art: 1. The top surface of the bag body forms bending parts towards the left and right sides of the open-top container, which can act as a tarpaulin and effectively prevent rain and snow from entering the container during railway transportation. At the same time, a top belt is arranged on the top of the bag body and fixed to the top surface of the bag body through the top belt, which can play a role in lifting the bag body. When the traction member on the top belt is connected to the rope loop on the outer side wall of the container, the top surface of the bag body can be positioned under the tension of the top belt, so as to suspend the bag body for facilitating the filling of powder materials into the bag body.

[0015] 2. A three-dimensional support framework is formed by the front cloth piece, the rear cloth piece and the transverse ring body reinforcing belt, and combined with the three-dimensional constraint system of the top transverse ring body, the middle transverse ring body and the vertical belt, the anti-expansion ability of the bag body is significantly improved. When discharging, after opening the container door, the above constraint system effectively disperses the lateral pressure of the powder material on the bag wall during discharging, reducing the risk of bag swelling and rupture. When discharging, the material will have a frictional force on the bag body and tend to drag the whole inner liner bag out of the container. Therefore, it is connected and reinforced with the rope loop in the container through the reinforcing belt to prevent the whole inner bag from being dragged out of the container during discharging. In addition, during the high-speed driving of the train, the wind force will have a tearing and destructive force on the top of the bag body. Through the criss-cross arrangement of the reinforcing belt, the bag body is fixed in a grid pattern, effectively preventing the tearing and damage of the wind force to the top of the bag body.

[0016] 3. The diagonal tension belt and the second hook of the extension section form a diagonal tension structure to prevent the front cloth piece from bulging and deforming when the discharge port is opened, and maintain the stable shape of the bag body.

[0017] 4. A separable fixing method, such as an adhesive method, is adopted between the reinforcing belt and the bag body. After the bag body is damaged, it can be replaced, and the reinforcing belt and the reinforcing cloth can be reused.

[0018] 5. The left bending part and the right bending part are arranged on the front cloth piece to enhance the lateral wrapping property. After the bag body is filled with powder materials, the left bending part and the right bending part will be extruded and pressed against the inner wall of the container, thereby improving the anti-expansion ability of the front cloth piece.
