The blocking component 109 includes an electromechanical box 118, a drive motor 119, a bearing seat 120, a flexible coupling 121, and a stop block 122. This solution addresses the problem in existing hydraulic door opening structures for dump truck bodies where workers still need to stand on the side to open the side door during unloading, potentially causing materials to spill out and posing a safety hazard to workers.

[0023] In this specific embodiment, the compartment 101, in conjunction with the two opening and closing components, is used for loading goods.

[0024] The plurality of rotating components 102 are respectively disposed on one side of the compartment 101; the plurality of mounting parts 103 are respectively disposed on one side of the plurality of rotating components 102; the plurality of assembly blocks 104 are respectively located on one side of the plurality of mounting parts 103; the compartment 101 is fixedly connected to the plurality of assembly blocks 104 and is located on one side of the plurality of assembly blocks 104; the assembly frame 106 is fixedly connected to the compartment 101 and is located on one side of the compartment 101; the hydraulic telescopic cylinder 107 is fixedly connected to the assembly frame 106 and is located on one side of the assembly frame 106; the pushing component 108 is disposed between the hydraulic telescopic cylinder 107 and the compartment door 105; the blocking component 109 is disposed on one side of the compartment 101; and the compartment door 105 is respectively assembled to the plurality of mounting parts via the plurality of assembly blocks 104. On 103, during loading, the hydraulic telescopic cylinder 107 on the assembly frame 106 controls the pusher 108 to close the door 105, and then the blocking member 109 assists in blocking the door 105. When unloading is required, the blocking member 109 is first controlled to move away from the door 105, and then the hydraulic telescopic cylinder 107 on the assembly frame 106 is controlled to drive the pusher 108 to lift the door 105 in conjunction with the rotating member 102 to open the compartment 101. Then, the goods inside the compartment 101 are unloaded. Through the contactless unloading method, the problem of existing hydraulic door opening structures for dump trucks is solved. Since workers still need to stand on the side to open the side door during the unloading process, materials may rush out from the side during the opening of the side door, which may cause safety hazards to the workers.

[0025] Secondly, the connecting part 110 is fixedly connected to the compartment 101 and located on one side of the compartment 101; the rotating shaft 111 is fixedly connected to the connecting part 110 and located on one side of the connecting part 110; the rotating block 112 is rotatably connected to the rotating shaft 111 and fixedly connected to the assembly 103 and located on one side of the rotating shaft 111. The connecting part 110 is used to support the rotating shaft 111 to support the rotating block 112 to rotate, and the rotating block 112 is used to support the opening and closing of the compartment door 105.

[0026] Next, the assembly frame 113 is fixedly connected to the rotating block 112 and is located on one side of the rotating block 112; the locking screw 114 is threadedly connected to the assembly frame 113 and is located on one side of the assembly frame 113.

Then, the locking screw 114 is twisted and inserted into the matching limiting hole on the assembly block 104 to complete the assembly of the door 105.

[0027] In addition, the push block 115 is fixedly connected to the output end of the hydraulic telescopic cylinder 107 and is located on one side of the hydraulic telescopic cylinder; the slider 116 is rotatably connected to the push block 115 and is located on one side of the push block 115; the slide rail 117 is fixedly connected to the door 105 and slidably connected to the slider 116 and is located on one side of the door 105. The hydraulic telescopic cylinder 107 is controlled to drive the push block 115 to slide on the slide rail 117 on the door 105, so as to lift the door 105 and open the compartment 101.

[0028] Furthermore, the electromechanical box 118 is fixedly connected to the compartment 101 and located on one side of the compartment 101; the drive motor 119 is fixedly connected to the electromechanical box 118 and located on one side of the electromechanical box 118; the bearing housing 120 is fixedly connected to the output end of the drive motor 119 and located inside the drive motor 119; the flexible coupling 121 is fixedly connected to the bearing housing 120 and located on one side of the bearing housing 120; the stop block 122 is fixedly connected to the flexible coupling 121 and located on one side of the flexible coupling 121. The electromechanical box 118 is used to support the assembly of the drive motor 119 and control the drive motor 119 to drive the flexible coupling 121 to drive the stop block 122 to rotate through the bearing housing 120, so that the stop block 122 can assist in blocking the compartment door 105.

[0029] In using this utility model, the compartment door 105 is respectively assembled onto multiple assembly parts 103 via multiple assembly blocks 104. During loading, the hydraulic telescopic cylinder 107 is controlled to drive the push block 115 to slide on the slide rail 117 on the compartment door 105, so that the compartment door 105 closes the compartment body 101. Then, the drive motor 119 is controlled to drive the elastic coupling 121 through the bearing seat 120 to drive the stop block 122 to rotate, so that the stop block 122 can assist in blocking the compartment door 105. When unloading is required, the drive motor 119 is first controlled to drive the bearing seat 120 and the elastic coupling 121 to rotate. The flexible coupling 121 drives the stop block 122 away from the door 105, and then controls the hydraulic telescopic cylinder 107 to drive the push block 115 to slide on the slide rail 117 on the door 105, so as to lift the door 105 and open the body 101, and then unload the goods inside the body 101. Through the contactless unloading method, the problem of existing hydraulic door opening structures for dump trucks is solved. Since workers still need to stand on the side to open the side door during the unloading process, materials may rush out from the side during the opening of the side door, which may cause safety hazards to the workers.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
