Description

Technical Field

[0001] The utility model relates to a container top cover, a container component and a railway transportation system, belonging to the technical field of railway transportation systems. Background Art

[0002] In railway transportation, detachable container covers can be used in conjunction with open-top containers. For example, the applicant's prior application CN216508328U discloses a railway transportation system. When transporting production materials to a factory via an open-top container, multiple container covers can be stacked on a freight flatbed truck and transported to the factory together. After arriving at the factory, the production materials are unloaded, and fly ash can be transported after the container cover is fastened to the open-top container, thereby realizing the pendulum-like transportation of railway transportation, making full use of railway transportation capacity, saving resources, and saving transportation costs. For example, the applicant's prior applications CN217349220U and CN217436691U also disclose similar container structures and railway transportation systems. Since the container cover and the open-top container can be used detachably, how to ensure that the two can be assembled firmly and easily installed during use is a problem that needs to be solved urgently. Utility Model Content

[0003] Therefore, an object of the present invention is to provide a container top cover that can be securely locked on an open top container, and further to provide a container assembly and a railway transportation system.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a container top cover, including a cover plate and a plurality of locking devices arranged on the lower end surface of the cover plate; the locking device includes a base for fixing to the cover plate, a locking arm hinged to the base and a support arm hinged to the locking arm; a first hinge shaft is provided at one end of the base, one end of the locking arm is installed on the first hinge shaft, and the other end can be rotated to the outside of the first hinge shaft for pressing on the lower end surface of the top frame of the open top container; the support arm is connected to the middle part of the locking arm through a second hinge shaft, and a first pin seat is also provided on the base, and a first pin hole is provided on the support arm. When the locking arm rotates to the working position for pressing the lower end surface of the top frame of the open top container, the first pin on the first pin seat can pass through the first pin hole to lock the support arm.

[0005] An auxiliary push rod is also fixed on the support arm. When the first latch passes through the first latch hole to lock the support arm, the auxiliary push rod presses against a blocking member arranged on the base.

[0006] The first latch seat serves as the blocking member.

[0007] A second latch hole is also provided on the support arm and located between the first latch hole and the second hinge axis.

[0008] A second latch seat is provided on the base and located inside the first hinge shaft, and a third latch hole is provided on the locking arm. The second latch on the second latch seat can be inserted into the third latch hole to lock the locking arm.

[0009] The locking arm is arc-shaped.

[0010] The locking arm comprises two locking plates arranged in parallel and a pressure roller connected between the two locking plates. The pressure roller is located at the end of the locking plate away from the first hinge shaft.

[0011] The pressing roller is a rubber pressing roller.

[0012] The support arm includes two support plates arranged in parallel and a gripping plate portion connected between the two support plates.

[0013] The utility model also provides a container assembly, comprising an open top container and the container top cover as described above.

[0014] The present invention also provides a railway transportation system, including a freight train and the container assembly as described above, wherein the freight train includes multiple freight flatbed trucks, and the open-top containers in the container assembly are fixed on the freight flatbed trucks; the container top cover in the container assembly can be fastened on the open-top container to close the open-top container.

[0015] By adopting the above technical solution, the container top cover, container assembly and railway transportation system of the present invention have the following beneficial effects compared with the prior art:

[0016] 1. Multiple locking mechanisms securely lock the container cover to the open-top container, effectively preventing it from becoming loose or unstable during transport. The improved locking mechanism design makes installation and removal of the cover even easier. By rotating the locking arm and inserting the latch, the cover can be quickly and securely connected and unlocked to the open-top container, improving operational efficiency.

[0017] 2. The locking arm is designed to be arc-shaped and equipped with a pressure roller, which can apply pressure evenly to ensure a close fit between the top cover and the top frame of the open top container, enhancing the stability of the connection. The use of a rubber pressure roller can avoid scratches on the surface of the open top container during the locking process.

[0018] 3. The support arm is equipped with an auxiliary push rod, which can apply torque to the blocking member through the push rod after locking, further strengthening the connection between the top cover and the container frame, and avoiding deformation or instability of the top cover during transportation.

[0019] 4. The effective sealing of the container roof ensures the safe transportation of items within the container, which is particularly important for the transportation of goods that require sealing or dust and water protection. Overall, the improved structure greatly improves the installation, fixation, and stability of the container roof during rail transportation, effectively improving transportation efficiency, reducing risks, and minimizing resource waste.
