[0021] This utility model provides a skeleton-type container self-unloading semi-trailer 101 with a hydraulic device, including a semi-trailer 101 and an unloading mechanism 102. The unloading mechanism 102 includes a carrying box 103, two side doors 104, a tail door 105, an installation assembly 106, multiple lifting assemblies 107 and multiple limiting assemblies 108. The installation assembly 106 includes an installation frame 109 and multiple slide rails 110. Each lifting assembly 107 includes a lifting cylinder 111, a lifting rod 112 and a top material seat 113. Each limiting assembly 108 includes a support plate 114 and a limiting block 115. The semi-trailer 101 includes a cab 116, a frame 117 and a bottom frame 118.

[0022] In this specific embodiment, each limiting component 108 is fixedly connected to the mounting component 106, each lifting component 107 is fixedly connected to the semi-trailer 101, the tailgate 105 is rotatably connected to the carrier box 103, both side doors 104 are rotatably connected to the carrier box 103, the carrier box 103 is slidably connected to each lifting component 107, each slide rail 110 is fixedly connected to the mounting frame 109, the mounting frame 109 is fixedly connected to the carrier box 103, the upper side of the top material seat 113 is slidably connected to the corresponding slide rail 110, the lower side of the top material seat 113 is rotatably connected to the lifting air rod 112, and the lower end of the lifting air rod 112 is fixedly connected to the output end of the lifting cylinder 111. The lifting cylinder 111 is fixedly connected to the semi-trailer 101, the limiting block 115 is fixedly connected to the corresponding mounting frame 109, the supporting plate 114 is fixedly connected to the semi-trailer 101, the bottom frame 118 is fixedly connected to the chassis 117, and the chassis 117 is rotatably connected to the cab 116. The carrier box 103 is provided with a side door 104 on both sides, and the carrier box 103 can be unloaded from both sides. By driving the lifting component 107 to adjust the height in either direction, the unloading of the carrier box 103 can be completed, making it more convenient to use. This design structure is reasonable and solves the problem that the main frame can only deflect in a fixed direction, and the placement position of the main frame is relatively fixed during the unloading process, making the unloading process inflexible.

[0023] Each of the limiting components 108 is located below the mounting component 106, each of the lifting components 107 is located above the semi-trailer 101, the tailgate 105 is located on one side of the carrying box 103, and the two side doors 104 are located on both sides of the carrying box 103. The carrying box 103 is located above each of the lifting components 107. The two side doors 104 and the tailgate 105 are kept in contact with the carrying box 103 by means of clamps. The transported materials can only be unloaded by manually disassembling the clamps during unloading.

[0024] Secondly, each of the slide rails 110 is located below the mounting frame 109, which is located below the carrier box 103. The upper side of the top material seat 113 is located inside the corresponding slide rail 110, and the lower side of the top material seat 113 is located above the lifting air rod 112. The lifting cylinder 111 is located above the semi-trailer 101. Since each top material seat 113 can slide within the corresponding slide rail 110 by the distance between the limiting block 115 and the supporting plate 114 after being raised, it will not interfere with the lifting air rod 112. When the carrier box 103 is in a stable state, the multiple supporting plates 114 can support the mounting frame 109 and the carrier box 103, preventing the mounting frame 109 and the carrier box 103 from directly acting on the top material seat 113 and the lifting air rod 112, thus reducing the service life of the lifting cylinder 111.

[0025] Meanwhile, the limiting block 115 is located inside the corresponding mounting frame 109, the abutment plate 114 is located above the semi-trailer 101, the bottom frame 118 is located above the chassis 117, and the chassis 117 is located on the back side of the cab 116. The bottom frame 118 provides support for the installation of each lifting cylinder 111. During unloading, the user can choose to unload from the left or right side of the carrying box 103, offering more options. At this time, all the lifting cylinders 111 on one side of the bottom frame 118 are activated, driving the corresponding lifting rod 112, so that... The top material seat 113 rises on the mounting frame 109, raising one side of the mounting frame 109 and the carrying box 103, thus completing the dumping of the material in the carrying box 103. It should be noted that during the dumping process, the upper end of each of the supporting plates 114 on the raised side needs to be disassembled to prevent the upper end of the supporting plate 114 from continuing to rotate and connect with the mounting frame 109. Meanwhile, the upper end of each of the supporting plates 114 on the other side remains continuously rotated and connected with the mounting frame 109, ensuring that the mounting frame 109 and the carrying box 103 will not detach due to the raising of the top material seat 113.

[0026] In this embodiment, both side doors 104 and the tail door 105 are kept in contact with the carrying box 103 by means of locking rods. The transported material can only be unloaded by manually disassembling the locking rods during unloading. Since each top material seat 113 can slide the distance between the limiting block 115 and the supporting plate 114 in the corresponding slide rail 110 after being raised, it will not cause movement interference with the lifting air rod 112. When the carrying box 103 is in a stable state, the multiple supporting plates 114 can support the mounting frame 109 and the carrying box 103, avoiding the mounting frame 109 and the carrying box 103 directly acting on the top material seat 113 and the lifting air rod 112, thus reducing the service life of the lifting cylinder 111. The bottom frame 118 is the mounting support for each lifting cylinder 111. For support, during unloading, the user can choose to unload from the left or right side of the carrying box 103, offering more options. At this time, all the lifting cylinders 111 on one side of the bottom frame 118 are activated, driving the corresponding lifting rods 112, causing the top material seat 113 to rise on the mounting frame 109, raising one side of the mounting frame 109 and the carrying box 103, completing the dumping of the material in the carrying box 103. It should be noted that during the dumping process, the upper end of each of the supporting plates 114 on the raised side needs to be disassembled to prevent the upper end of the supporting plate 114 from continuing to rotate and connect with the mounting frame 109, while the upper end of each of the supporting plates 114 on the other side remains rotating and connected with the mounting frame 109, ensuring that the mounting frame 109 and the carrying box 103 will not detach due to the raising of the top material seat 113.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. 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.
