Description

Technical Field

[0001] The utility model relates to the technical field of loading support platforms, in particular to a universal segmented telescopic cartridge loading support platform. Background Art

[0002] The process of loading a cartridge primarily involves pushing the cartridge into or pulling it out of the storage and transport tube, a process that presents significant integration challenges. The cartridge is placed on a cartridge support, which is placed on a cartridge support platform. The storage and transport tube is placed on a tube support, which is placed on the storage and transport tube support platform. A pulling device facilitates the loading and unloading of the cartridge. Loading and unloading the storage and transport tube must be safe, ensuring smooth and seamless entry and precise docking. The trial assembly of the cartridge and the storage and transport tube must be easy to operate, with good processability and cost-effectiveness.

[0003] The loading support platform must not only consider the needs of the storage and transportation tubes and ammunition loading, and solve the problem of difficult loading alignment, but also consider the needs of transportation, transfer, and storage. The loading process requires precise docking, and the support platform must ensure a certain strength and precision.

[0004] Currently, there are two main types of loading support platforms. One is a split-type loading support platform, where a missile rack and a storage and transport barrel rack are docked, with an adjustment mechanism aligning the two sections of guide rails. During loading, a sprocket is manually cranked, pushing a transfer plate fixed to the front end of the missile's slide, pushing it into the launch box. To withdraw the missile, the active sprocket is cranked in the opposite direction, pulling the missile out of the launch box. This system, which uses a carriage for direct loading, lacks a missile support seat, and has fixed guide rails with no adjustable width. This makes it unsuitable for loading larger barrels and ammunition, presenting significant limitations.

[0005] The other type is a mobile ammunition loading vehicle, a type of ammunition transport device used for ammunition transfer and testing. Its upper and lower sections are split, allowing for multi-dimensional lifting and leveling, but it cannot be used for horizontal loading of ammunition and storage tubes. Due to the large size and weight of storage tubes and ammunition, loading is technically challenging, and there is no suitable support platform for ammunition loading. Utility Model Content

[0033] See Figure 1-2 One embodiment of the present invention provides a segmented retractable cartridge loading support platform, which is mainly divided into two parts: a storage and transportation cartridge support platform and a cartridge support platform. The storage and transportation cartridge support platform and the cartridge support platform are connected by a slide rail, thereby achieving retractability.

[0034] For details, see Figure 3 The main structure of the storage and transportation barrel support platform is a fixed frame 1, which consists of a pair of main beams and multiple connecting beams welded between the beams. In a preferred embodiment, the fixed frame 1 is a double-beam structure formed by rectangular steel pipe weldments. It consists of two long rectangular steel pipes as the dual main beams, with several equal-length rectangular steel pipes welded in between to form the double-beam main frame.

[0035] Underneath the storage and transport cylinder support platform are multiple parking mechanisms 3 for adjusting the position. These parking mechanisms 3 consist of columns and a base, providing height adjustment. In a preferred embodiment, the columns are pairs of equal-length rectangular steel tubes welded to the lower portion of the main beam of the fixed frame 1. These columns have threaded holes machined into them for mounting the lead screws. The base, preferably a disc-shaped base, is fixedly connected to the lower portion of the lead screws. By rotating the lead screws up and down, the base is raised and lowered, ensuring the storage and transport cylinder support platform is grounded and securely parked.

[0036] A plurality of casters 4 are further provided below the storage and transportation barrel support platform for moving the storage and transportation barrel support platform. The number of casters 4 is preferably four.

[0037] See Figure 5-6Multiple sets of rollers 7 are mounted on the fixed frame 1 to facilitate sliding movement between the storage and transport cylinder support platform and the elastic support platform. The rollers 7 can be constructed from multiple sets of rolling bearings and are mounted on the fixed frame 1 via roller mounting shafts 12. Preferably, a reinforcement frame 6 is welded to the fixed frame 1 where the rollers 7 are located to provide local reinforcement for the fixed frame 1. The roller mounting shafts 12 pass through the fixed frame 1 and the reinforcement frame 6, securing the rollers 7 to the inner side of the fixed frame 1.

[0038] In some embodiments, the fixed frame 1 is further provided with multiple cylinder support mounting plates 5 for mounting fixing seats adapted to different types of storage and transportation cylinders. The fixed frame 1 is provided with limiting holes 11 for limiting and fixing the elastic support platform when it is extended and retracted into place.

[0039] See Figure 4 The main structure of the elastic support platform is the push-pull frame 2. The push-pull frame 2 is similar in structure to the fixed frame 1, consisting of a pair of main beams and multiple connecting beams welded between them. In a preferred embodiment, the push-pull frame 2 is a double-beam structure formed by rectangular steel pipe weldments. It consists of two long rectangular steel pipes as the dual main beams, with several equal-length rectangular steel pipes welded in between to form the double-beam main frame.

[0040] A parking mechanism 3 is provided beneath the elastic support platform. This mechanism 3 consists of columns and a base, and features height adjustment. In a preferred embodiment, the columns are pairs of equal-length rectangular steel pipes welded to the lower portion of the main beam of the push-pull frame 2. These columns have threaded holes machined into them for mounting the lead screw. The base, preferably a disc-shaped base, is fixedly connected to the lower portion of the lead screw. By rotating the lead screw up and down, the base is raised and lowered, ensuring the elastic support platform is grounded and securely parked.

[0041] A plurality of casters 4 are further provided below the elastic support platform for moving the elastic support platform. The number of casters 4 is preferably four.

[0042] See Figure 5-6 The push-pull frame 2 is also provided with a roller mounting slot 8, and the roller 7 on the fixed frame 1 is configured to fit within this slot and slide within it. This creates a sliding connection between the storage and transport drum support platform and the spring-loaded support platform, enabling telescopic movement. Preferably, the spacing between the two main beams of the storage and transport drum support platform is greater than the spacing between the two main beams of the spring-loaded support platform, allowing the roller 7 to fit neatly within the roller mounting slot 8 of the spring-loaded support platform, achieving telescopic function.

[0043] In some embodiments, the push-pull frame 2 is provided with two front and rear stopper holes 11: a front stopper hole and a rear stopper hole. Longitudinal fasteners 13 are inserted through corresponding stopper holes 11 in the fixed frame 1 and the push-pull frame 2 to secure the storage and transport cylinder support platform and the elastic support platform. These longitudinal fasteners 13 include, but are not limited to, connecting bolts.

[0044] Preferably, the push-pull frame 2 is further provided with a U-shaped linear guide 9, on which are mounted multiple sets of guide blocks 10. The forward and backward movement of the guide blocks 10 on the linear guide 9 enables the loading of cartridges. Furthermore, the guide blocks 10 can be connected to various types of connecting mechanisms, adapting to various types of supports and achieving platform versatility.

[0045] In the present invention, the support platform only serves as a support during the loading process of the cartridge. During storage and transportation, the cartridge support platform and the storage and transportation cartridge support platform can be quickly adjusted to their retracted or extended states. Once adjusted to their proper positions, the parking mechanism 3 adjusts the height of the cartridge support platform, allowing the casters 4 to leave the ground.

[0046] The workflow of the loading support platform of the present invention is as follows:

[0047] Before the loading operation, unfold the two sections of the support platform in the contracted and overlapped state. First, rotate the parking mechanisms 3 on both sides of the storage and transportation tube support platform to the ground, and the casters 4 are suspended in the air. The rollers 7 of the storage and transportation tube support platform are embedded in the roller mounting grooves 8 of the elastic support platform. Remove the connecting bolts 11 in the rear end limit hole of the elastic support platform, and pull the elastic support platform along the slide rail in the opposite direction of the storage and transportation tube support platform; when the front end limit hole 11 of the elastic support platform is aligned with the limit hole 11 of the storage and transportation tube support platform, insert the bolts to fasten the two sections of the support platform together. At this time, the two sections of the support platform are in an extended state. Rotate the parking mechanisms 3 on both sides of the elastic support platform to the ground, and the casters 4 are suspended in the air. The loading operation can be carried out after the two sections of the support platform are leveled.

[0048] After the loading operation is complete, the two extended support platforms are retracted. Confirm the order of precedence by suspending the parking mechanism 3, grounding the casters 4, and inserting the rollers 7 of the storage and transport cylinder support platform into the roller mounting slots 8 of the elastic support platform. Remove the connecting bolts from the front limit holes 11 of the elastic support platform and push the elastic support platform along the slide rails toward the storage and transport cylinder support platform. When the rear limit holes 11 of the elastic support platform align with the limit holes 11 of the storage and transport cylinder support platform, insert the bolts to tighten them together. At this point, the two support platforms are in a collapsed, telescoping state.

[0049] In summary, the segmented, retractable cartridge loading support platform provided by this utility model allows for rapid deployment and retractable fixation, ensuring precise docking and loading of storage and transport cartridges and cartridges. By retracting the cartridge support platform during transport and other non-use conditions, the overall length is reduced by 40%, facilitating transportation and saving floor space. This solves the challenges of bulky loading support equipment, both in alignment and transport, and meets diverse specifications and dimensions.
