Abstract
Description
Technical Field
[0001] This invention belongs to the field of equipment manufacturing, and in particular relates to an integrated self-unloading and leveling device for modular shelters. Background Technology
[0002] Electronic equipment container houses, serving as equipment carrying platforms and operator workspaces, are typically transported by flatbed trucks. During operation, the container needs to be landed and leveled. They are currently widely used in civilian and military fields such as communications command and radar. Due to their heavy weight, hoisting is inconvenient and results in poor mobility. To improve convenience, self-unloading mechanisms have been designed.
[0003] Patent CN 212474666 U, proposing a "novel self-unloading container," uses a hydraulic cylinder to drive the tipping plate, achieving self-unloading of goods. However, it is not suitable for the overall self-loading, unloading, and leveling of the container. Patent CN212173293 U, proposing a "novel self-loading container structure," achieves self-unloading through extension legs and leveling legs. However, its extension legs have only one degree of freedom, meaning they cannot move along the width of the container, nor along its height, and the required stroke of the leveling legs is relatively long. Therefore, there is currently a lack of a compact and reliable solution for self-unloading and leveling of container containers. Summary of the Invention
[0004] To overcome the shortcomings of the existing technology, this invention proposes an integrated self-unloading and leveling device for modular shelters, which improves the self-loading, unloading and leveling efficiency of modular shelter equipment vehicles, provides reliable support for the modular shelter after leveling, and maintains its levelness for a long time.
[0005] The present invention provides an integrated self-unloading and leveling device for a container, comprising 3 fixed lugs, 4 connecting rods, 9 pins, 1 support base, 2 movable lugs, 1 electric cylinder, and 1 leveling leg installed on the container.
[0006] The three fixed supports include an upper fixed support (21), a middle fixed support (22), and a lower fixed support (23). The upper fixed support (21) serves as the rotating fixed end support for the electric cylinder (26), and the two are rotatably connected by the upper pin (1) of the electric cylinder. The middle fixed support (22) serves as the rotating fixed end support for the upper connecting rod (14) and the upper-middle connecting rod (5), and are rotatably connected by the upper pin (2) of the upper connecting rod and the upper pin (3) of the upper-middle connecting rod, respectively. The lower fixed support (23) serves as the rotating fixed end support for the lower connecting rod (7), and is rotatably connected by the upper pin (6) of the lower connecting rod.
[0007] The two movable supports include an upper movable support (24) and a lower movable support (25). The upper movable support (24) serves as a connecting support for the rotating end of the upper connecting rod (14), and the two are rotatably connected through the lower pin (13) of the upper connecting rod. The lower movable support (25) serves as a rotating end support for the middle and lower connecting rods (11) and the lower connecting rod (7), and is rotatably connected through the lower pin (10) of the middle and lower connecting rods and the lower pin (9) of the lower connecting rods, respectively.
[0008] The movable upper support (24) and movable lower support (25) are fixedly connected to the leveling leg (27) respectively, driving the leveling leg to move.
[0009] The upper and middle connecting rods (5) are rotatably connected to the electric cylinder (26) via the lower pin (4) of the electric cylinder, and are rotatably connected to the lower connecting rod (11) via the connecting pin (12) of the upper and middle connecting rods.
[0010] The support base (8) is fixed on the lower connecting rod (7) to provide auxiliary support and limit the connection shaft between the upper connecting rod (5) and the lower connecting rod (11) in the working state of the device.
[0011] The beneficial effects of this invention are as follows:
[0012] 1. High installation adaptability. The leveling outriggers and the container of this invention are integrated into one unit, requiring no further assembly when not in use, making it convenient to use and ensuring good safety.
[0013] 2. Small size and convenient layout. The device of this invention has a small thickness, which reduces the size along the length of the vehicle during transportation. After being recycled to the transportation state, its width and height are small, meeting the transportation limit requirements. Attached Figure Description

Detailed Implementation
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] The self-unloading and leveling integrated device consists of four sets, installed at the four corners of the container. Three fixed supports—upper support 21, middle support 22, and lower support 23—are installed on the corresponding support surfaces of the container and connected by screws. The mounting surfaces serve as the foundation for supporting the device during movement and operation, and must ensure adequate strength and rigidity. The mounting surfaces of the four sets are at approximately the same height.
[0021] The process of the device changing from the working state to the transport state is as follows: the shortening of the electric cylinder (26) drives the lower pin (4) of the electric cylinder to press... Figure 1 The movement to the upper right causes the upper connecting rod (5) to rotate around the upper pin (3) of the upper connecting rod. The upper connecting rod (5) and the lower connecting rod (11) change from an approximately straight line to a broken line, causing the lower connecting rod (7) to rotate around the upper pin (6) of the lower connecting rod. This, in turn, causes the lower movable support (25) to rotate around the pin (6). The upper ends of the lower connecting rod (7) and (14) rotate around the upper pin (2) of the upper connecting rod and the upper pin (6) of the lower connecting rod, respectively. The lower ends are rotated through the lower pin (9) of the lower connecting rod, the lower pin (13) of the upper connecting rod, the upper movable support (24), the lower movable support (25), and the leveling leg (27), forming a parallelogram mechanism. This drives the leveling leg to rotate and rise to the transport state. The movement from the transport state to the working state is the reverse process.
[0022] Figure 3 In the transport state of the device, both the electric cylinder 26 and the leveling leg 27 are in the shortest stroke state. When they retract to the shortest stroke state, the limit switch provides a trigger signal, and the control system cuts off the power to the motor to stop it.
[0023] Figure 4This is the operating state of the device. In this state, the electric cylinder 26 is in its longest stroke position. When it extends to the longest position, a limit switch provides a trigger signal, and the control system cuts off power to the motor to stop it. The leveling leg 27 stops at the corresponding stroke according to the needs of supporting leveling. When it extends to the longest position, a limit switch provides a trigger signal, and the control system no longer allows the corresponding leveling leg to extend, only to retract it, to ensure the safety of the system.
[0024] This invention is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this invention should be included within the scope of protection of this invention.
