Description

Technical Field

[0001] This utility model relates to the field of drone fire extinguishing bomb transfer auxiliary device, and in particular to a bomb rack. Background Technology

[0002] When using drones for firefighting, fire extinguishing bombs need to be installed on the drones. In actual firefighting operations, the drones and fire extinguishing bombs are stored in an integrated container on a transfer vehicle. Upon arrival at the fire site, the drone is detached, and the fire extinguishing bombs are installed on it for firefighting. Figure 1 As shown, fire extinguishing bomb 1 is placed inside fire extinguishing bomb storage box 2, which is then stacked inside an integrated container. The number of fire extinguishing bomb storage boxes 2 stacked in a single layer is limited. When stacked in multiple layers, the uppermost fire extinguishing bomb storage boxes 2 may tilt during the operation of the transfer vehicle, posing a safety hazard of tipping over when workers retrieve them from the integrated container. Furthermore, when workers remove fire extinguishing bombs from the fire extinguishing bomb storage boxes 2, they need to put the empty fire extinguishing bomb storage boxes 2 back into the integrated container. They also need to remove the filled fire extinguishing bomb storage boxes 2 to make room before placing the empty ones into the integrated container of the transfer vehicle. During this process, the workers experience high labor intensity, fatigue, and low work efficiency when moving the fire extinguishing bomb storage boxes 2. Summary of the Invention

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0030] like Figure 2As shown, a type of ammunition rack includes at least one set of storage racks 3. The storage racks 3 are profiled frame structures with long storage cavities inside. The width of the storage cavity matches the width of the fire extinguishing ammunition storage box 2, and the length of the storage cavity is an integer multiple of the length of the fire extinguishing ammunition storage box 2. In this embodiment, the length of the storage cavity is 7 times the length of the fire extinguishing ammunition storage box 2, allowing for the placement of 7 fire extinguishing ammunition storage boxes 2. A bottom plate 301 is provided at the bottom of the storage cavity along its length. The bottom plate 301 is a smooth flat plate, facilitating the pushing and pushing of the fire extinguishing ammunition storage boxes 2. Guide and limiting rods 302 are provided on both sides of the storage cavity along its length, such as... Figure 3 As shown, positioning blocks 201 are provided on both sides of the fire extinguishing bomb storage box 2, and guide limiting rods 302 are provided above the positioning blocks 201. The distance between the two guide limiting rods 302 matches the width of the fire extinguishing bomb storage box 2. The guide limiting rods 302 guide and limit the fire extinguishing bomb storage box 2 in all directions. First door stops 303 are provided at both ends of the storage cavity of the storage rack 3 to prevent the fire extinguishing bomb storage box 2 from being pushed out from both ends of the storage cavity during transportation.

[0031] like Figure 2 As shown, the first door stop 303 is a rotatable door stop, including a first stop bar 3031, a first pivot seat 3032, and a first support seat 3033. The first pivot seat 3032 is mounted on the storage rack 3. One end of the first stop bar 3031 is rotatably mounted on the first pivot seat 3032, and the other end of the first stop bar 3031 is provided with the first support seat 3033. The first support seat 3033 is fixedly mounted on the storage rack 3 to support the first stop bar 3031.

[0032] The bottom of storage shelf 3 can also be set as follows: Figure 4 The slide rail 304 is shown. The reduced contact area between the slide rail 304 and the fire extinguishing bomb placement box 2 reduces friction and can reduce the labor intensity of the workers.

[0033] The bottom of storage shelf 3 can also be set as follows: Figure 5 The roller rail 305 shown is a roller conveyor line composed of several sets of rollers. The roller rail 305 and the fire extinguishing bomb placement box 2 experience rolling friction, greatly reducing the labor intensity of the workers.

[0034] Based on the size of the loading space allocated to the transfer vehicle, a reasonable modular ammunition rack is set up. After the transfer vehicle arrives at the designated fire extinguishing location, the side wings of the transfer vehicle open. The staff selects one side port of the storage cavity as the retrieval outlet of the fire extinguishing ammunition box 2, and the other side port as the inlet of the empty fire extinguishing ammunition box 2. When retrieving the fire extinguishing ammunition box 2 with ammunition, the staff rotates the first door stop 303 of the retrieval outlet, rotates the first stop bar 3031, and opens the retrieval port. After the staff takes out the fire extinguishing ammunition box 2 with ammunition, they rotate the first stop bar 3031 again, so that the first stop bar blocks laterally at the retrieval port. After the staff takes out the fire extinguishing ammunition from the fire extinguishing ammunition box 2, the empty fire extinguishing ammunition box 2 is pushed in from the inlet. During the pushing process, the fire extinguishing ammunition box 2 with ammunition in the storage cavity will be pushed forward to the retrieval outlet. This process is repeated until the fire extinguishing ammunition in the storage cavity is taken out. Then, the staff starts to retrieve fire extinguishing ammunition from another set of storage cavities.

[0035] To further reduce the labor intensity of staff and improve the efficiency of bullet retrieval, the storage rack 3 can be tilted during bullet retrieval, with the tilt direction being from the push-in end of the storage cavity to the retrieval end.

[0036] like Figure 6 As shown, a tilting device is installed below the storage rack 3. The tilting device includes a rotating base 4, a lifting assembly 5, and a support roller assembly 6. The rotating base 4 is located below the storage rack 3 and at the outlet end of the storage cavity. The lifting assembly 5 is located below the storage rack 3 and at the inlet end of the storage cavity. The support roller assembly 6 is located below the storage rack 3 and between the rotating base 4 and the lifting assembly 5. Multiple sets of support roller assemblies 6 are provided to support the ammunition rack when it is placed horizontally, so that the ammunition rack is placed stably.

[0037] like Figure 6 As shown, the rotating base 4 includes a first base plate 401, a bearing seat 402, a second rotating shaft 403, and a rotating support plate 404. The first base plate 401 is a U-shaped plate, and the bottom of the U-shaped plate is fixedly mounted on the transfer vehicle. Bearing seats 402 are provided on the vertical plates on both sides of the U-shaped plate. The second rotating shaft 403 is inserted through the shaft hole of the bearing seat 402. The rotating support plate 404 is fixedly mounted on the second rotating shaft 403. The top of the rotating support plate 404 is fixedly mounted on the bottom of the storage rack 3.

[0038] like Figure 6 , Figure 7As shown, the lifting assembly 5 includes a second base plate 501, a lifting cylinder 502, a roller mounting seat 503, a roller 504, a top plate 505, a guide strip 506, and a fixing plate 507. The second base plate 501 is fixedly mounted on the transfer vehicle. The lifting cylinder 502 is mounted on the second base plate 501. The output shaft of the lifting cylinder 502 is directed towards the storage rack 3. The roller mounting seat 503 is fixedly mounted at the end of the output shaft of the lifting cylinder 502. The roller 504 passes through the roller mounting seat 503. The bottom of the storage rack 3 is provided with a top plate 505. When the lifting cylinder 502 lifts, the roller 504 abuts against the top plate 505 and lifts the storage rack 3. The roller 504 rolls and rubs on the top plate 505 to reduce the friction during lifting. A guide strip 506 is provided on the top plate 505. The guide strip 506 is along the rolling direction of the roller 504 and is located on both sides of the roller 504. The channel between the two sets of guide strips 506 is the rolling channel of the roller 504. A fixing plate 507 is also provided on the second bottom plate 501. The top of the fixing plate 507 is matched with the top plate 505. When the transfer vehicle is moving, the fixing plate 507 and the top plate 505 are tightened with bolts to ensure the stability of the storage rack 3 during the transfer process. When the storage rack 3 needs to be tilted when it reaches the designated location, the fastening bolts between the fixing plate 507 and the top plate 505 are loosened and removed.

[0039] like Figure 6 As shown, the support roller assembly 6 includes a third base plate 601, a rotating roller 602, and a soft sheath 603. The bottom of the third base plate 601 is fixedly mounted on the transfer vehicle. The rotating roller 602 is mounted on the third base plate 601 and supports the storage rack 3. The soft sheath 603 is wrapped around the outer edge of the rotating roller 602 to cushion the impact force on the storage rack 3 during transportation. The soft sheath 603 can be made of rubber, sponge, etc.

[0040] Furthermore, after the fire extinguishing bomb placement box 2 at the outlet end is taken out, in order to prevent the next fire extinguishing bomb placement box 2 from sliding out, the door stop at the outlet end is structurally optimized. At the same time as taking out the fire extinguishing bomb placement box 2 at the outlet end, the next fire extinguishing bomb placement box 2 is blocked. Therefore, the optimized door stop structure second door stop 7 is set at both ends of the storage cavity of the storage rack 3.

[0041] like Figure 6 , Figure 8As shown, the second door stop 7 includes a second stop bar 701, a second pivot seat 702, a second support seat 703, a first rotating shaft 704, a bearing with a seat 705, and a blocking plate 706. The second pivot seat 702 is mounted on the storage shelf 3, and the first rotating shaft 704 passes through the second pivot seat 702. One end of the second stop bar 701 passes through the first rotating shaft 704 of the second pivot seat 702, and the other end of the second stop bar 701 is provided with the second support seat 703. The second support seat 703 is fixedly mounted on the storage shelf 3 to support the second stop bar 701. The first rotating shaft 704 extends along the storage shelf 3. The first rotating shaft 704 extends in the direction of degree and extends to the position between the two sets of fire extinguishing bomb placement boxes 2 at the outlet end. A baffle plate 706 is provided at the extended end of the first rotating shaft 704. The baffle plate 706 is set perpendicular to the second baffle 701. When the second baffle 701 is set to block laterally, the baffle plate 706 is set to block vertically downward. When the second baffle 701 is set to open vertically upward, the baffle plate 706 is set to block laterally. A seated bearing 705 is also provided on the first rotating shaft 704 to make the rotation of the first rotating shaft 704 more stable. In this embodiment, two sets of seated bearings 705 are provided, and the number can be set according to the actual situation.

[0042] like Figure 8 As shown, the top of the baffle plate 706 is also provided with a conical top 7061, which provides initial guidance when the baffle plate 706 rotates. Figure 6 As shown, the fire extinguishing bomb storage box 2 is equipped with a locking assembly 202. When the fire extinguishing bomb storage boxes 2 are arranged one by one on the storage shelf 3,

[0043] When the fire extinguishing bomb placement boxes 2 are in the storage cavity, a gap is formed between them by the locking assembly 202. The baffle plate 706 is set at the gap position. When the baffle plate 706 is in the lateral blocking state, it is located in the gap space.

[0044] After the transfer vehicle arrives at the designated firefighting location, its side wings open. Workers first loosen and remove the bolts securing the fixed plate 507 and the top plate 505, separating them. Then, workers open the second door stop 7 at the outlet end of the storage cavity by rotating the second stop lever 701 vertically upwards. Simultaneously, the blocking plate 706 rotates from a vertically downward position to a horizontal blocking position. At this point, the lifting assembly 5 activates, and the lifting cylinder 502 pushes the output shaft upwards. The roller 504 lifts the storage rack 3, causing it to rotate around the rotating base 4 at a certain angle, tilting it. Workers can then remove the fire extinguishing grenade storage box 2 without much physical exertion. After removing the fire extinguishing grenade storage box 2, workers rotate the second stop lever 701 from a vertically open position to a horizontal blocking position, while the blocking plate 706 rotates from a horizontal blocking position to a vertically downward open position. After the staff removes the fire extinguishing bombs from the fire extinguishing bomb storage box 2, the empty fire extinguishing bomb storage box 2 is pushed in through the inlet. During the pushing process, the fire extinguishing bomb storage box 2 with the bombs in it will be pushed forward to the retrieval outlet. This process is repeated until the fire extinguishing bombs in the storage cavity are removed. Then, fire extinguishing bombs are retrieved from another set of storage cavities.

[0045] like Figure 9 As shown, the ammunition rack in this embodiment can be formed by multiple storage racks 3 arranged in a matrix to form different numbers of storage racks. The quantity, size and composition of the racks are diverse. The size of the ammunition racks is determined by the size of the provided placement space, making it flexible and adaptable.
