Description

Technical Field

[0001] This utility model relates to a tilting cover for a vehicle compartment, belonging to the technical field of containers. Background Technology

[0002] Containers are the most common cargo loading devices in the current logistics industry. Depending on the type of cargo being loaded, different locations on the container have cargo entrances and exits.

[0003] Existing top-opening containers typically have folding covers, which not only result in a small opening area but also occupy space above the container, easily causing interference with other external equipment or structures, thus limiting their usability. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cargo box flip-top cover that not only operates smoothly and reliably, but can also be completely flipped to the side wall of the cargo box, thereby allowing large machinery to operate without obstacles and improving loading and unloading efficiency.

[0005] To solve the above problems, the specific technical solution of this utility model is as follows: A car body flip cover has an opening at the upper end of the car body, and a cover plate that opens in the width direction of the car body is provided at the opening; one end of several parallel linkage arms is hinged to the outer side of the cover plate, and the other end of the linkage arms is hinged to the side plate or side column of the car body; a power crossbeam is provided on the front and rear sides of the opening at the upper end of the car body, and a lower seat of a hydraulic cylinder is fixedly connected to the middle position of the power crossbeam. The cylinder seats of hydraulic cylinders are respectively hinged to both sides of the lower seat of the hydraulic cylinder. The piston rod of the hydraulic cylinder is hinged to the flip arm through a linkage mechanism. One end of the flip arm is hinged to the power crossbeam, and the other end is hinged to the inner side of the cover plate.

[0006] The linkage mechanism includes a swing arm and a tilting arm; one end of the swing arm and the tilting arm are both hinged to the rotating shaft, and the piston rod of the hydraulic cylinder is also hinged to the rotating shaft; the other end of the swing arm is hinged to the power beam, and the other end of the tilting arm is hinged to the end of the tilting arm.

[0007] Each cover plate has an L-shaped flip arm seat at its inner end, and the end of the flip arm is hinged to the flip arm seat.

[0008] One of the cover plates has a waterproof cover plate on its inner end side, and the other cover plate has a waterproof groove I on its inner side, with the waterproof cover plate covering the waterproof groove I.

[0009] The waterproof cover plate has an inwardly bent edge at its end, and the bottom edge of the bent edge is in contact with the upper surface of the cover plate on the opposite side.

[0010] The bottom of the waterproof cover is provided with a waterproof baffle I, which is set inside the waterproof groove I.

[0011] The bottom of the waterproof baffle I is provided with an inclined surface that bends toward the opposite cover plate.

[0012] The power beam is provided with side fan square tubes and walkway square tubes on both sides respectively. A waterproof edge with a bent edge structure is provided between the side fan square tubes and the walkway square tubes. The top surface of the waterproof edge is flush with the top surface of the walkway square tube and contacts the bottom surface of the cover plate. A linkage arm upper seat is provided at the hinge of the cover plate and the linkage arm. When the cover plate is closed, the linkage arm upper seat sits in the opening groove provided in the side fan square tube.

[0013] The cover plate is provided with a waterproof baffle II on the lower surface near the upper seat of the linkage arm. When the cover plate is closed, the waterproof baffle II is located inside the waterproof edge.

[0014] The tilting arm, swing arm, and tilting arm are double-layered structures, located on both sides of the rotating shaft, with the piston rod of the hydraulic cylinder hinged to the middle of the rotating shaft.

[0015] The tilting cover of the carriage in this application adopts the above-described structure and has the following advantages: 1. The operation is labor-saving and efficient, completely replacing the heavy physical labor that requires multiple people to cooperate in traditional tarpaulin covering and rope binding. It completely eliminates the repeated purchase costs of consumables such as tarpaulins and ropes, and also avoids the risk of cargo damage caused by tarpaulin damage and personnel injury during operation. 2. Revolutionary improvement in loading and unloading efficiency: The large opening design for bulk cargo and hoisted cargo maximizes the size of the cover plate, almost covering the entire top of the container. The top cover can be fully opened, and the two covers can be flipped to the sides of the container during loading, allowing large machinery (such as grab buckets and grain unloaders) to operate without obstruction. The loading and unloading efficiency is improved compared to the side door method, and the dwell time of vehicles in the plant is greatly reduced. 3. The container hydraulic tilting cover, powered by a hydraulic system, provides powerful and stable force, completely replacing cumbersome and time-consuming manual operation. Operators can open and close the cover in tens of seconds simply by using a control button or handheld remote control, greatly improving work efficiency and reducing labor intensity. The rapid opening and closing directly translates into higher vehicle turnover and more daily transport trips, creating more revenue. 4. Smooth and synchronous operation with high reliability. The innovative double-sided boom mechanism and hydraulic synchronizer ensure that the cover plate operates synchronously on both sides during opening and closing, effectively eliminating the lack of coordination and smoothness in opening and closing actions caused by jamming, abnormal noise or structural deformation. The hydraulic system operates smoothly, with less impact on containers and cargo, and the overall mechanism has a long service life and low failure rate. 5. Excellent sealing performance protects goods. The surrounding waterproof structure and optimized compression design provide excellent waterproof and dustproof effects, effectively protecting the goods inside the box from rain. 6. Compact structure and strong adaptability: The entire system is compactly designed and does not take up too much extra space. It can be adapted to containers of various standard sizes. The optimized linkage trajectory enables the cover to effectively avoid obstacles when opening, making it very suitable for use in space-constrained yards, docks and railway freight yards.

[0021] Figure 6 A plan view showing the carriage with the flip-top cover open. Detailed Implementation

[0022] like Figures 1 to 6 As shown, a car body flip cover has an opening at the upper end of the car body, and a cover plate 1 that opens in the width direction of the car body is provided at the opening. Several parallel linkage arms 5 are hinged to one end of the outer side of the cover plate 1, and the other end of the linkage arms 5 is hinged to the side plate or side column of the car body. Power beams 15 are provided on the front and rear sides of the opening at the upper end of the car body. The lower seat of the hydraulic cylinder 11 is fixedly connected to the middle position of the power beam 15. The cylinder seats of hydraulic cylinders 13 are respectively hinged to the two sides of the lower seat of the hydraulic cylinder 11. The piston rod of the hydraulic cylinder 13 is hinged to the flip arm 7 through the linkage mechanism. One end of the flip arm 7 is hinged to the power beam 15, and the other end is hinged to the inner side of the cover plate 1.

[0023] The linkage mechanism includes a swing arm 8 and a tilting arm 9; one end of the swing arm 8 and the tilting arm 9 are hinged to the rotating shaft 16, and the piston rod of the hydraulic cylinder 13 is also hinged to the rotating shaft 16; the other end of the swing arm 8 is hinged to the power beam 15, and the other end of the tilting arm 9 is hinged to the end of the tilting arm 7.

[0024] Each cover plate 1 has an L-shaped flip arm seat 10 at its inner end, and the end of the flip arm 7 is hinged to the flip arm seat 10.

[0025] One of the cover plates 1 has a waterproof cover plate 2 on its inner end side, and the other cover plate 1 has a waterproof groove I14 on its inner side, with the waterproof cover plate 2 covering the waterproof groove I14.

[0026] like Figure 5 As shown, the waterproof cover 2 has an inwardly curved edge at its end, and the bottom edge of the curved edge is attached to the upper surface of the cover 1 on the opposite side. A waterproof baffle I3 is provided at the bottom of the waterproof cover 2, and the waterproof baffle I3 is disposed within a waterproof groove I14. The bottom of the waterproof baffle I3 has an inclined surface that curves towards the opposite cover 1. When rainwater enters the compartment through the gaps in the waterproof cover 2, the rainwater generates a high-speed vortex. The flow velocity of the vortex is counteracted by the waterproof baffle I3, and the water then re-enters the space between the waterproof baffle I3 and the waterproof groove I14, reducing rainwater splashing, preventing it from entering the compartment, and draining out of the compartment through the waterproof groove I14.

[0027] The power beam 15 is provided with a side fan square tube 17 and a walkway square tube 18 on both sides respectively. A waterproof edge 12 with a bent edge structure is provided between the side fan square tube 17 and the walkway square tube 18. The top surface of the waterproof edge 12 is flush with the top surface of the walkway square tube 18 and contacts the bottom surface of the cover plate 1. A linkage arm upper seat 4 is provided at the hinge of the cover plate 1 and the linkage arm 5. When the cover plate 1 is closed, the linkage arm upper seat 4 sits in the opening groove provided in the side fan square tube 17.

[0028] like Figure 4 As shown, a waterproof baffle II19 is provided on the lower surface of the cover plate 1 near the upper seat of the linkage arm 4. When the cover plate 1 is closed, the waterproof baffle II19 is located inside the waterproof flange 12. When rainwater enters from the gap of the upper seat of the linkage arm 4, the rainwater generates a high-speed vortex. The flow velocity of the vortex is counteracted by the waterproof baffle II19, and the rainwater re-enters the space between the waterproof flange 12 and the waterproof baffle II19, reducing rainwater splashing, entering the box body, and being discharged from the compartment through the waterproof flange 12.

[0029] The flipping arm 7, the swing arm 8, and the flipping arm 9 are double-layered structures and are located on both sides of the rotating shaft 16, respectively. The piston rod of the hydraulic cylinder 13 is hinged to the middle of the rotating shaft 16.

[0030] The working process of this application is as follows: The cover plate 1 is initially in a closed state. When it is necessary to open the cover plate 1, the hydraulic cylinder 13 is activated to retract. The piston rod of the hydraulic cylinder 13 pushes the rotating shaft 16, and the swing arm 8 and the tilting arm 9 rotate accordingly. The tilting arm 9 drives the hinged tilting arm 7 to rotate upward and outward. After rotating 180°, the cover plate 1 tilts downward and folds with the linkage arm 5 until it bends and falls almost parallel to the side wall of the carriage. The hydraulic cylinder 13 extends and operates in the opposite direction to complete the closing of the cover plate 1.
