Description

Technical Field

[0001] This utility model relates to the field of air cargo technology, and in particular to a rapid loading and unloading device for air cargo barrier nets. Background Technology

[0002] In today's air cargo sector, with cargo volumes continuously increasing, transportation efficiency and safety have become core concerns. Traditional air cargo barrier net loading and unloading methods have many drawbacks. Their connections often rely on complex bolt structures, requiring operators to tighten them one by one during installation, consuming a significant amount of time and manpower. At airports with frequent cargo turnover, this greatly prolongs the loading and unloading cycle and reduces aircraft utilization efficiency.

[0003] A search revealed the publication number CN222238729U. This publication discloses a training barrier net, comprising several uprights with several support rods rotatably mounted on both sides of each upright. A base is mounted at the bottom of each support rod, and the base is slidably mounted within the support rod via a connecting rod. A locking assembly is provided between the connecting rod and the support rod. The hinged connection between the support rod and the horizontal uprights allows for flexible adjustment of the barrier net's angle to meet different training needs. Furthermore, the base and connecting rod are spring-loaded to ensure the support rod's length adaptability during rotation, enabling free height adjustment. The locking assembly ensures the barrier net is securely locked after adjustment, improving safety. This significantly enhances the adaptability, convenience, and safety of the training barrier net, meeting the needs of diverse training scenarios.

[0004] The "locking component" mentioned in the aforementioned patent, in actual use, includes a screw 8, which is matched and connected to the support rod 2. By rotating the screw 8, the displacement of the connecting rod 3 can be controlled; that is, after the screw 8 and the connecting rod 3 are disconnected, the connecting rod can move freely to adjust the height of the base 4, and then the screw 8 can be rotated in the opposite direction to lock again. For ease of operation, a handwheel 9 is installed on the outside of the screw 8, allowing the user to easily rotate the screw 8 to complete height adjustment and locking. Therefore, to address the above-mentioned problems, a rapid loading and unloading device for air cargo barrier nets is proposed to solve the aforementioned problems. Utility Model Content

[0014] As a further description of the above technical solution:

[0015] A connecting support block is fixedly connected to the bottom of the sliding connecting column, a supporting barrier net is fixedly connected to the outside of the connecting support block, and the outside of the connecting support block is slidably connected to the inside of the supporting protective shell.

[0016] As a further description of the above technical solution:

[0017] The external of the support fixing block is fixedly connected to a connecting fixing ring, and the internal of the connecting fixing ring is slidably connected to the outside of the support protective shell;

[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rapid loading and unloading device for air cargo blocking nets, after the rotating motor is started, it drives the driving wheel to rotate through transmission. The driving wheel then drives the driven wheel one, which in turn causes the driven wheel two to move together. The rotation of this series of wheels drives the moving rack and sliding connecting column to move up and down. The connecting support block then rises and falls synchronously at the top of the sliding connecting column, realizing flexible adjustment of the height of the blocking net. Its beneficial effects are significant. It can accurately adjust the height of the blocking net according to the different sizes, weights, and materials of the cargo, ensuring effective interception of various types of cargo and greatly enhancing the applicability and reliability of the device in complex air cargo scenarios.

[0024] 2. In this utility model, after the telescopic cylinder is activated, it pushes the telescopic connecting rod, which in turn drives the sliding limit block to move, and the sliding fixing block slides within the sliding limit block. When the fixing ring is placed outside the connecting fixing ring, the sliding fixing block slides inward and tilts up, quickly fixing the position of the fixing connecting ring, realizing the rapid fixing of the telescopic mechanism and the quick-release mechanism, improving the assembly efficiency of the device. In frequent loading and unloading scenarios in air cargo, it can quickly complete the connection of components, reduce the waiting time for operation, and enhance the overall stability of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 This utility model provides an embodiment of a rapid loading and unloading device for air cargo barrier nets, comprising a support protective shell 1. The device is characterized by: a quick-release mechanism 3 fixedly connected to the bottom of the support protective shell 1; a telescopic mechanism 2 slidably connected inside the support protective shell 1; the telescopic mechanism 2 including a rotary motor 201 serving as the power core for its lifting action; a lifting assembly 209 rotatably connected to the inner side of the support protective shell 1; the lifting assembly 209 including a drive wheel 202 fixedly connected to the output end of the rotary motor 201; the motor rotation drives the drive wheel 202 to rotate synchronously; the output end of the rotary motor 201 fixedly connected inside the drive wheel 202; and a driven wheel 203 rotatably connected to the inner side of the support protective shell 1, meshing with the drive wheel 202. Driven by the driving wheel 202, the driven wheel 203 is externally connected to the driven wheel 204, which is connected to the driven wheel 203, receives the power transmitted by the driven wheel 203 and rotates; on the other hand, it meshes with the moving rack 206. The driven wheel 203 and the driving wheel 202 are meshed with each other. The moving rack 206 is slidably connected inside the supporting protective shell 1 and meshes with the driven wheel 204. Driven by the driven wheel 204, it moves linearly along the internal track of the supporting protective shell 1. The sliding connecting column 205 is slidably connected inside the supporting protective shell 1 and slides inside the supporting protective shell 1. The bottom of the column is fixedly connected to the moving rack 206 and the top is fixedly connected to the connecting support block 207. The driven wheel 204 and the moving rack 206 are meshed with each other.

[0033] The moving rack 206 is fixedly connected to the outside of the sliding connecting column 205. The driven wheel 204 is rotatably connected to the inside of the support protective shell 1. The bottom of the sliding connecting column 205 is fixedly connected to the connecting support block 207, which is fixed to the top of the sliding connecting column 205 and fixedly connected to the supporting barrier net 208. The supporting barrier net 208 is fixedly connected to the outside of the connecting support block 207. It is used to intercept cargo in air transport and prevent the cargo from shifting or tipping over due to turbulence, airflow and other factors during transportation. The outside of the connecting support block 207 is slidably connected to the inside of the support protective shell 1. The lifting assembly 209 is composed of the driving wheel 202, driven wheel 203, driven wheel 204, moving rack 206 and other components. Through the wheel group transmission and rack movement driven by the motor, the rotational motion of the motor is converted into the vertical lifting motion of the supporting barrier net 208, so as to realize the height adjustment function.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The quick-release mechanism 3 includes a telescopic cylinder 301, which serves as the power source for the quick-release mechanism 3. The output end of the telescopic cylinder 301 is fixedly connected to a telescopic connecting rod 302, which transmits the telescopic movement of the cylinder. The telescopic connecting rod 302 is slidably connected to a support fixing block 303, which provides an installation base for components such as the connecting fixing ring 304, ensuring their movement trajectory and enhancing the reliability of the mechanism's operation. The support fixing block 303 is fixedly connected to a connecting fixing ring 304, which is slidably connected to the support fixing block 303 and can move within a certain range. The connecting fixing ring 304 is slidably connected to the outside of the support protective shell 1. The support fixing block 303 is fixedly connected to a sliding limit block 305, which is fixed inside the support fixing block 303, providing a sliding track for the sliding fixing block 306 and limiting its range of movement.

[0035] The sliding limit block 305 has a sliding fixed block 306 internally connected to it. When the telescopic cylinder 301 pushes the telescopic connecting rod 302 to move, the sliding fixed block 306 moves accordingly. The sliding fixed block 306 is externally fixedly connected to a connecting fixed round block 307, which connects the sliding fixed block 306 and the fixed connecting ring 308, and plays the role of transmitting force and assisting in fixing, ensuring the stability of the fixed connecting ring 308 during the connection process. The connecting fixed round block 307 is externally slidably connected to a fixed connecting ring 308, which is used to connect the telescopic mechanism 2 with other external equipment. The inner side of the fixed connecting ring 308 is slidably connected to the outer side of the connecting fixed ring 304. The outer side of the connecting fixed ring 304 is slidably connected to a second supporting fixed block 309, which provides sliding support for the telescopic cylinder 301 to ensure its smooth telescopic movement. The telescopic cylinder 301 is slidably connected to the outside of the second supporting fixed block 309.

[0036] Working principle: When the rotating motor 201 starts running, it drives the drive wheel 202 to move, which in turn drives the driven wheel 203 to move, which in turn drives the driven wheel 204 to move, which in turn drives the rack 206 and the sliding connecting column 205 to move the connecting support block 207 at the top of the sliding connecting column 205, which in turn drives the supporting barrier net 208 to move. This changes the height of the supporting barrier net 208 and the connecting support block 207, allowing for the interception of different materials as needed.

[0037] When the telescopic cylinder 301 starts running, it drives the telescopic connecting rod 302 to move, which in turn drives the sliding limit block 305 to move. This causes the sliding fixing block 306 to slide inside the sliding limit block 305. When the fixing ring 308 is placed outside the fixing ring 304, the sliding fixing block 306 slides inward, causing the sliding fixing block 306 to tilt up, thereby fixing the position of the fixing ring 308 and achieving a quick fixing effect. This fixes the telescopic mechanism 2 onto the quick-release mechanism 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
