Description

Technical Field

[0001] This utility model relates to the field of missile military equipment loading and unloading technology, specifically to a missile storage and transportation box loading and unloading device. Background Technology

[0002] Given that the 5-ton and 10-ton hazardous materials transport vehicles are all box trucks, the presence of the roof makes direct loading by crane impossible. When transporting products like the storage and delivery boxes for a certain type of missile, loading the boxes into box trucks is difficult, requiring the use of 13-meter-long trailers, resulting in a transportation cost of 21 yuan / ton / km. Designing a dedicated loading and unloading device would allow loading the products onto 10-ton box trucks at a cost of 9 yuan / ton / km; loading them onto 5-ton box trucks would reduce the cost to 6.5 yuan / ton / km, significantly lowering transportation costs. Therefore, a loading and unloading device is needed to load the storage and delivery boxes onto 5-ton or 10-ton box trucks, meeting the requirements for safety, reliability, and economy in the loading and unloading process. Utility Model Content

[0003] To meet the above technical requirements, the purpose of this utility model is to provide a missile storage and launch box loading and unloading device that fully considers the economic cost of product transportation, safety and convenience during loading and unloading, and can easily realize manual loading and unloading of missile storage and launch boxes to vans according to the actual conditions of different workshops.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a missile storage and launch box loading and unloading device, including a transfer trolley for placing missile storage and launch boxes, a support frame for facilitating loading of the transfer trolley, and a winch assembly placed on one side of the support frame and providing power to the transfer trolley; the transfer trolley includes a transfer support frame and multiple universal wheels at the bottom of the transfer support frame, and eye bolts as fixing points for steel wire ropes are provided at the bottom of the transfer support frame; the support frame adopts an inclined support frame or a support platform, the slope of the inclined support frame is set to 3.2°, and the support platform is in a horizontal state, and both the inclined support frame and the support platform are provided with support rollers for supporting steel wire ropes; the winch assembly is located on one side of the support frame, including a winch bracket and a winch body provided on the surface of the winch bracket, and two winch pulley sets for threading steel wire ropes are provided at the bottom of the winch bracket. During operation, the steel wire rope from the winch body passes through the two winch pulleys, then winds around the support rollers, and then passes through the eye bolts. The winch body is manually cranked to drive the transfer trolley to move.

[0005] Furthermore, the winch body adopts a self-locking worm gear winch.

[0006] The transfer support frame is made up of multiple crossbeams and longitudinal beams welded together. Handles for easy manual pushing are welded at both ends of the transfer support frame. Lifting eye screws are set at the bottom of the crossbeams. The longitudinal beams are also symmetrically provided with positioning pins for accurate positioning of the hoisting and storage boxes. The bottom of the longitudinal beams is provided with multiple transfer auxiliary wheels and adjustable feet.

[0007] The inclined support frame includes a front inclined support and a rear inclined support that is detachably connected to the front inclined support. Both the front and rear inclined supports are steel frame structures, with the bottom made of several welded steel pipes and the top provided with a support plate. The support plate is fixed with corner braces on both sides, and support rollers are provided on the surface of the support plate.

[0008] The support platform is a steel frame structure, and the bottom of the support platform is equipped with multiple transfer auxiliary wheels and adjustable support legs, with support rollers located on the surface of the support platform.

[0009] The winch support is a steel frame structure, and multiple winch auxiliary wheels are also provided at the bottom of the winch support.

[0010] This utility model consists of a storage and transportation container transfer trolley, an inclined support frame, a winch assembly, and a support platform. To facilitate flexible and convenient loading and unloading of the containers, a storage and transportation container transfer trolley was designed, comprising a transfer support frame and four omnidirectional wheels at the bottom. This allows for flexible movement of the containers even without a crane. Considering the actual conditions of a workshop in our factory, where the external platform is 1.05m high, inconsistent with the floor height of the hazardous materials transport vehicle, it is impossible to directly load the containers by pushing the transfer trolley. Through theoretical calculations, an inclined support frame with a reasonable slope was designed to connect the platform and the vehicle. A worm gear winch with steel wire ropes is then used to pull the storage and transportation container transfer trolley. Simultaneously, manual directional control allows for the safe and quick loading of containers with supports onto 5-ton or 10-ton box trucks. Finally, the wheels of the transfer trolley are locked, and the auxiliary transfer wheels are adjusted to support the weight of the container. The containers are reliably secured using ropes through locking points inside the vehicle. When loading and unloading containers in a platformless workshop, there is no need for inclined support frames. The height of the support platform can be freely adjusted to accommodate the loading and unloading of 5-ton or 10-ton box trucks. At the same time, the bottom is equipped with multiple transfer auxiliary wheels to ensure that the support platform is reliably fixed and easy to move.

[0011] The technical problem this utility model aims to solve is the high cost of transporting a certain type of missile storage and launch box using large hazardous materials transport vehicles, while loading and unloading it on small hazardous materials transport vehicles is difficult. To address this, a reasonably structured, simple, and convenient loading and unloading device is provided, which can load the box onto a small hazardous materials transport vehicle, thereby reducing transportation costs.

[0012] The beneficial effects of this utility model are: under field testing or in the absence of a crane, the transfer trolley can carry the storage and transportation boxes and move them flexibly; the storage and transportation boxes can be safely and conveniently loaded onto small 5-ton or 10-ton box-type dangerous goods transport vehicles, greatly reducing transportation costs; it is applicable to the loading and unloading of storage and transportation boxes under different workshop conditions; it has low cost, short processing cycle, simple assembly, and convenient operation.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Appendix Figure 1-5 This is one embodiment of the present invention, which discloses a missile storage and launch box loading and unloading device, which consists of a transfer trolley 1, an inclined support frame 2, a winch assembly 3 and a support platform 4.

[0021] Figure 2The transfer trolley consists of a transfer support frame and four omnidirectional wheels at the bottom. The transfer support frame is made of Q235A steel and is composed of multiple crossbeams 7 and longitudinal beams 6 to support the weight of the entire storage and transportation container, ensuring its rigidity and strength. Handles 10 are welded to both ends of the transfer support frame for easy manual pushing of the trolley. Eye bolts 11 are welded to the bottom of the crossbeams 7 at both ends of the transfer support frame as fixing points for the wire rope, used in conjunction with the winch assembly 3 during loading and unloading. Omnidirectional lifting rings 8 are welded to the surface of the longitudinal beams for easy lifting. Additionally, four positioning pins 12 are welded to the upper part of the longitudinal beams for accurate positioning during lifting of the storage and transportation container. To reduce cushioning force, pine wood pads are used at the contact points between the positioning pins 12 and the container body. To facilitate loading and unloading and save time and effort, the four wheels of the transfer trolley are made of high-strength, high-elasticity and wear-resistant transfer auxiliary wheels 13. The wheels are equipped with brakes, are 5 inches in size, and have a rated load of 1.7 tons. The four wheels can withstand the weight of a fully loaded storage and transportation box. At the same time, four adjustable support feet 14 are installed at the bottom of the support frame. When the storage and transportation box is placed on the ground or in the transport vehicle, it can work with the transfer auxiliary wheels 13 to support the weight of the box and avoid the transfer auxiliary wheels 13 from being subjected to stress for a long time, thus avoiding safety hazards.

[0022] Due to the unsuitable platform height, in order to accommodate the loading and unloading operations of 5-ton or 10-ton box trucks transporting hazardous materials, theoretical calculations were performed to... Figure 3 The inclined support frame is designed with a slope of 3.2° and consists of a front inclined support and a rear inclined support. The inclined support frame is a steel frame structure welded from several steel pipes, with corner braces 17 welded to the left and right sides of the support plate for fixation. The width of the support plate is 1200mm. The floor of the 5-ton van is 1160mm high, and only the front inclined support 15 is needed to connect the platform and the van. The slope length of the front inclined support 15 is 2296mm.

[0023] The height of the 10-ton van floor is 1300mm, so a rear inclined support 16 needs to be connected to the front inclined support 15 to make it level with the height of the van floor. The total length of the slope of the front and rear inclined supports is 4677mm. In addition, the inclined support frame 2 is equipped with a support roller 19 for supporting steel wire ropes to work with the winch assembly 3, making the loading and unloading process more labor-saving.

[0024] Figure 4The winch assembly includes a winch support, a winch body mounted on the winch support, a winch pulley block 23, and a winch auxiliary wheel 24. The winch body is a worm gear winch. The winch support is a steel frame structure welded from 12 steel pipes, with a self-locking worm gear winch installed on the upper part. The load capacity is 500kg, which fully meets the theoretically calculated thrust required for the storage and transportation container to move upward along the inclined support frame. The bottom is fixed to the winch pulley block 23 by two corner braces, allowing the wire rope to pass through. At the same time, the winch auxiliary wheel 24 is installed for adjustment and fixation. The winch assembly is used in conjunction with the inclined support frame and support platform to make the loading and unloading process more labor-saving.

[0025] like Figure 5 As shown, the bottom of the support platform is constructed and welded from a square tube steel frame structure. The bottom is also equipped with adjustable legs 14 and transfer auxiliary wheels 24. The adjustable legs are made of square tubes with evenly distributed screw holes. Each leg of the support platform is connected to the adjustable leg with two screws, allowing for free adjustment of the platform's height according to different loading and unloading conditions. To ensure reliable fixation and easy movement of the support platform, multiple transfer auxiliary wheels are provided at the bottom. Support rollers 19 with supporting steel wire ropes are installed at both the front and rear ends, used in conjunction with the winch assembly 3. The support platform is suitable for loading and unloading of containers in workshops without platforms, and its height can be freely adjusted according to the loading vehicle.

[0026] The specific process of using this utility model is as follows:

[0027] When loading missile storage and launch containers onto a 5-ton van in a workshop of our factory, the first step is to lock the wheels of the transfer trolley 1 and use an overhead crane to hoist the storage and launch container 5 onto the transfer trolley 1. Then, a front inclined support 15 is placed on the platform, making it level with the floor of the 5-ton van. The transfer trolley 1 is manually pushed onto the front inclined support 15. The wire rope on the worm gear winch is then wound around the support rollers above the front inclined support 15 through the two lower winch pulley sets 23 and connected and fixed to the lifting eye bolts 11 at the rear of the transfer trolley. The worm gear winch is manually cranked to pull the storage and launch container transfer trolley, while simultaneously controlling the direction manually, to safely and quickly load the storage and launch container onto the 5-ton van. Finally, the wheels of the storage and launch container transfer trolley are locked, the adjustable support legs 14 and the transfer auxiliary wheels 13 are adjusted to support the weight of the container, and the container is reliably fixed by using ropes through the locking points inside the van.

[0028] To load the storage and transport container onto a 10-ton box truck, simply connect a rear inclined support 16 to the front inclined support 15 to make it flush with the floor of the 10-ton box truck. The remaining steps are the same as loading a 5-ton box truck. Unloading is the reverse.

[0029] When loading and unloading containers in workshops without platforms, inclined support frames are unnecessary; instead, a support platform with auxiliary transfer wheels and adjustable height is required. First, adjust the adjustable legs to align the support platform with the floor of a 5-ton or 10-ton box truck. Then, use an overhead crane to hoist the container transfer trolley 1 onto the support platform 4. The wire rope from the hand-cranked worm gear winch is looped around the support rollers 19 at the rear of the support platform and connected to the lifting eye bolts 11 at the rear of the container transfer trolley. The support platform 4 is then manually pushed to the truck bed. Finally, the container is pulled into the truck bed using the hand-cranked worm gear winch. Unloading is the reverse process.

[0030] The above describes the basic principles and main features of this utility model. The slope of the inclined support, the pulling force required for the storage and unloading trolley, and the specifications of the worm gear winch in this utility model have all been theoretically calculated and experimentally verified. The channel steel, lifting rings, winches, etc., used are all standard parts and can be purchased on the market. The specific connection methods of each part all adopt conventional methods such as bolts and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art.
