Description

Technical Field

[0001] This utility model relates to the field of heavy cargo transportation technology, and in particular to a fast-loading heavy cargo transportation fastening and protection structure. Background Technology

[0002] Large cargo such as spacecraft capsules are typically characterized by their large size, heavy weight, and irregular shape (e.g., flat bottom and semi-circular top). During transportation, especially by road or rail, the cargo needs to be reliably secured to the transport platform (such as a flatbed truck) to resist displacement, overturning, or damage that may be caused by inertial forces, wind, vibration, etc.

[0003] Currently, when transporting such spacecraft, traditional customized wooden crates or steel frame structures are commonly used for fixing and protection. This method is inconvenient in terms of loading, requiring the cabin to be hoisted and its attitude adjusted multiple times before it can be placed into a fixed container, which is inefficient and increases the risk of hoisting. In terms of fastening, steel wire ropes and chains are usually used with chain hoists or tensioners for binding and fixing. This method relies on the experience of the operators, and the fastening force is difficult to quantify and standardize. Insufficient pre-tightening force can cause the cargo to loosen during transportation, or excessive tightness can damage the precision structure. More importantly, existing shock absorption measures are often quite simple, such as laying rubber pads at the bottom of the cargo. Their shock absorption effect is limited and lacks specificity, making it difficult to effectively filter the complex road spectrum vibrations and impacts transmitted from the chassis of the transport vehicle. This poses a potential threat to the precision instruments inside the spacecraft cabin. In addition, traditional protective structures are mostly enclosed, making it impossible to visually inspect the condition of the cargo during transportation. Furthermore, the top protection is mostly fixed, with poor adaptability and inability to be quickly adjusted according to cabins of different sizes. A single structure usually serves only one or one type of transportation mission, resulting in low versatility and a huge waste of resources.

[0004] Therefore, in view of the shortcomings of the above-mentioned fixed packaging and wire rope binding, such as poor adaptability, low loading and unloading efficiency, uneven fastening force, and rudimentary shock absorption measures, a quick-assembly type fastening and protection structure for large transport goods can be designed, which can achieve quick clamping, effective shock absorption, all-round protection, and good versatility. Utility Model Content

[0005] In order to overcome the problems of poor adaptability, low loading and unloading efficiency, uneven fastening force, and rudimentary shock absorption measures in the existing structure which uses fixed packaging and steel wire rope binding.

[0006] The technical solution of this utility model is as follows: a fast-assembly type large cargo transport fastening and protection structure, including a bottom support frame assembly, a fixed end plate and a movable end plate. The bottom support frame assembly is used to support the spacecraft body. The fixed end plate is fixedly installed on one end of the upper surface of the bottom support frame assembly along the length direction. The movable end plate is movably arranged on the other end of the upper surface of the bottom support frame assembly. The two are arranged parallel to each other. It also includes a top protection assembly, which includes two sets of parallel fixed seats, several sets of arched beams spaced apart between the fixed seats, and several protective plates covering the outside of the arched beams.

[0007] Preferably, the cargo is loaded and positioned at the bottom. Large cargo, such as the spacecraft cabin, is hoisted onto the bottom support frame assembly. Then, the cargo is longitudinally secured by driving the movable end plate to move along the upper surface of the bottom support frame assembly, so that it, together with the fixed end plate, clamps the cargo from both ends. Finally, the top protection assembly is installed and adjusted to a suitable height according to the actual height of the cargo. The top protection assembly moves to the upper surface of the spacecraft cabin, forming a sturdy top protective cover with internal cushioning, protecting the cargo from falling objects and environmental factors.

[0008] Preferably, the bottom support frame assembly includes two parallel main longitudinal beams, several crossbeams that are fixedly connected to the two main longitudinal beams, a pressure plate laid on the crossbeams, a buffer pad layer on the upper surface of the pressure plate, and multiple fixed bases located below the main longitudinal beams.

[0009] Preferably, the movable end plate is driven and positioned by two sets of long threaded columns that penetrate its body. The long threaded columns are fixedly connected to the fixed end plate, and the movable end plate is tightened by adjusting nuts screwed onto the long threaded columns.

[0010] Preferably, shock-absorbing and protective components are provided inside the fixed end plate and the movable end plate.

[0011] As a preferred option, the shock-absorbing and protective component is a multi-chamber interconnected damping airbag, which includes multiple independent but interconnected small air chambers through damping holes.

[0012] Preferably, the shock absorption and protection components include a damping shock absorber, a clamping plate installed on the telescopic end of the damping shock absorber, and a honeycomb damping plate fixedly connected to the inner wall of the clamping plate.

[0013] Preferably, the top protective assembly also includes a guide rail fixedly connected to the outside of the main longitudinal beam and a soft pad fixedly connected to the inner wall of the protective plate. The fixing seat is fixedly connected to the end of the guide rail, and the fixing seat is threaded with bolts for fixing the protective plate.

[0014] Preferably, the arched beam adopts a telescopic structure, which includes two sets of fixed legs, a telescopically insertable arc beam into the two sets of fixed legs, and a pin for adjusting and fixing the arc beam. The fixed legs are connected to the sliding parts in the fixed guide rail.

[0015] The beneficial effects of this utility model are as follows: It realizes modularization and quick assembly of fastening and protection, effectively improving operation efficiency and safety. By combining fixed end plates with movable end plates and using long threaded columns and adjusting nuts for driving, it achieves precise and controllable longitudinal clamping of the spacecraft body, fundamentally avoiding cargo loosening or structural damage caused by improper fastening. At the same time, the top protection component adopts an adjustable height arched beam and modular protection plate, which can quickly adapt to spacecraft bodies of different sizes, forming a stable protection space, greatly shortening preparation time and allowing observation of cargo en route. A multi-level, multi-directional integrated shock absorption system is designed, which significantly improves the dynamic protection performance during transportation, providing unprecedented flexible and reliable fastening protection for the spacecraft body and greatly reducing transportation risks.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1 Please see Figures 1-4 This utility model provides an embodiment of a quick-assembly type large cargo transport fastening and protection structure, including a bottom support frame assembly 1, a fixed end plate 2, and a movable end plate 3. The bottom support frame assembly 1 is used to support the spacecraft cabin. The fixed end plate 2 is fixedly installed on one end of the upper surface of the bottom support frame assembly 1 along the length direction. The movable end plate 3 is movably arranged on the other end of the upper surface of the bottom support frame assembly 1. The two are arranged parallel to each other. It also includes a top protection assembly 4, which includes two sets of parallel fixed seats 401, several sets of arched beams 402 spaced apart between the fixed seats 401, and several protective plates 403 covering the outside of the arched beams 402.

[0020] The bottom support frame assembly 1 includes two parallel main longitudinal beams 101, several crossbeams 102 fixedly connecting the two main longitudinal beams 101, a pressure plate 103 laid on the crossbeams 102, a buffer pad layer 104 disposed on the upper surface of the pressure plate 103, and a number of fixed bases 105 disposed below the main longitudinal beams 101.

[0021] Meanwhile, the movable end plate 3 is driven and positioned by two sets of long threaded columns 5 that penetrate its body. The long threaded columns 5 are fixedly connected to the fixed end plate 2, and the movable end plate 3 is tightened by adjusting nuts 6 screwed onto the long threaded columns 5.

[0022] In addition, shock-absorbing and protective components are provided in the fixed end plate 2 and the movable end plate 3. The shock-absorbing and protective components are multi-chamber interconnected damping airbags 701, which include multiple independent but interconnected small air chambers through damping holes.

[0023] In addition, the top protective assembly 4 also includes a guide rail 404 fixedly connected to the outside of the main longitudinal beam 101 and a soft pad 406 fixedly connected to the inner wall of the protective plate 403. The fixing seat 401 is fixedly connected to the end of the guide rail 404. The fixing seat 401 is threaded with a bolt 405 for fixing the protective plate 403. The arched beam 402 adopts a telescopic structure, which includes two sets of fixed legs 4021, an arc beam 4022 telescopically inserted into the two sets of fixed legs 4021, and a pin 4023 for adjusting and fixing the arc beam 4022. The fixed legs 4021 are connected to the sliding parts in the fixed guide rail 404.

[0024] During operation, the cargo is loaded and positioned at the bottom. Large items such as spacecraft cabins are hoisted onto the surface of the pressure plate 103 laid above the crossbeam 102. The cargo directly contacts the buffer pad 104 on the upper surface of the pressure plate 103. The buffer pad 104 effectively absorbs and cushions some of the vertical vibrations and impacts during transportation. The entire bottom support frame assembly 1 is securely connected to the platform of the transport vehicle through multiple fixed bases 105 below its main longitudinal beam 101. Then, the cargo is longitudinally secured by tightening the adjusting nut 6 installed on the long threaded column 5, which drives the movable end plate 3 to move along the upper surface of the bottom support frame assembly 1, so that it clamps the cargo from both ends together with the fixed end plate 2. During this process, the multi-chamber interconnected damping airbag 701 set inside the fixed end plate 2 and the movable end plate 3 will be in close contact with the ends of the cargo. When the cargo tends to move longitudinally during transportation, the multi-chamber interconnected damping airbag will activate. Each independent small air chamber within 701 is interconnected through damping holes, utilizing the resistance of airflow between chambers to dissipate energy, thereby achieving efficient longitudinal shock absorption and buffer protection. Finally, the top protective assembly 4 is installed. The span of the arch beam 402 is adjusted according to the actual height of the cargo: by pulling the retractable arc beam 4022 inserted into the two sets of fixed legs 4021, after adjusting to the appropriate height, the pin 4023 is inserted into the corresponding hole to lock it. Then, the assembled arch beam 402 is connected to the sliding part in the guide rail 404 through its fixed legs 4021 and slid along the guide rail 404 to the predetermined position. Next, several protective plates 403 are moved to the upper surface of the spacecraft compartment. The soft pads 406 on the inner wall of the protective plates 403 can prevent scratching the top of the cargo. The bolts 405 are screwed in to tighten, thereby forming a sturdy top protective cover with internal buffer to protect the cargo from falling objects and environmental factors.

[0025] Example 2 Please see Figure 5 The difference from Embodiment 1 is that the shock absorption and protection component includes a damping shock absorber 702, a clamping plate 703 installed on the telescopic end of the damping shock absorber 702, and a honeycomb shock absorber plate 704 fixedly connected to the inner wall of the clamping plate 703.

[0026] The shock absorption and protection component absorbs longitudinal impact energy through the damping shock absorber 702. Its telescopic end pushes the clamping plate 703 to fit tightly against the goods. The honeycomb shock absorption plate 704 on the inner wall of the clamping plate 703 further disperses and buffers local pressure through the deformation of its honeycomb structure, thus achieving multi-level shock absorption and protection.

[0027] Through the above steps, modularization and quick assembly of fastening and protection are achieved, effectively improving operational efficiency and safety. By combining the fixed end plate 2 with the movable end plate 3 and using the long threaded column 5 and adjusting nut 6 for driving, precise and controllable longitudinal clamping of the spacecraft cabin is achieved, fundamentally avoiding cargo loosening or structural damage caused by improper fastening. At the same time, the top protection component 4 adopts an adjustable height arched beam 402 and modular protection plate 403, which can quickly adapt to spacecraft cabins of different sizes, forming a stable protective space, greatly shortening preparation time and allowing observation of cargo en route. A multi-level, multi-directional integrated shock absorption system is designed, significantly improving the dynamic protection performance during transportation, providing unprecedented flexible and reliable fastening protection for the spacecraft cabin, and greatly reducing transportation risks. This solves the problems of poor adaptability, low loading and unloading efficiency, uneven fastening force, and rudimentary shock absorption measures in existing structures that use fixed packaging and wire rope binding.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
