Detailed Implementation

[0033] A rapid lifting device for interference and camouflage comprises three main parts: a multi-stage rapid lifting device 1, a concealment and shielding device 2, and a buried foundation 3. This rapid lifting device for interference and camouflage has two states: an initial state and a working state. These two states of the system are described as follows: Figure 1 and Figure 2 As shown:

[0034] In a rapid-lift device used for jamming and camouflage, the multi-stage rapid-lift device 1 serves to raise the "false target." The device's retracted state (initial state) is as follows: Figure 3 As shown.

[0035] In its initial state, the multi-stage rapid lifting device, under the action of the power source... Figure 3 The spindle 10 rotates, driving the various internal mechanisms of the device to operate. Under the action of these mechanisms, the rapid lifting devices at each stage extend, achieving the required working state. The working state of the device is as follows: Figure 4 As shown.

[0036] In the rapid lifting device, the concealment cover 2 serves to open the working channel of the multi-stage rapid lifting device 1 when the system is in operation. In the initial state of the system, it closes the working channel of the multi-stage rapid lifting device 1 to conceal the device and protect personnel safety. Furthermore, this concealment cover 2, combined with the same paint scheme as the surrounding area, effectively disguises the rapid lifting device, thus protecting the system. Additionally, in the initial state, the concealment cover 2 functions similarly to the ground (e.g., it can support people and vehicles walking on it). The concealment cover 2 in the initial state... Figure 5 As shown.

[0037] When the system is in operation, the drive unit 6 of the concealment mask device 2 drives the cover plate assembly 4 to retract to the right along the track 5, opening the working channel of the multi-stage rapid lifting device 1. The concealment mask device 2 in operation is as follows: Figure 6 As shown.

[0038] In the rapid lifting device, the buried foundation 3 provides installation space for the multi-stage rapid lifting device 1 and the concealed shielding device 2. The buried foundation 3, as shown... Figure 7 As shown.

[0039] The flange 7 below the multi-stage rapid lifting device 1 is installed on the buried foundation 3 using anchor bolts 9, nuts, and washers 8, as shown below. Figure 8 As shown.

[0040] The structure of the multi-stage rapid lifting device 1 is as follows: Figure 9 As shown.

[0041] This section uses the extension of the first stage of a multi-stage rapid lifting device as an example to illustrate the lifting process of the multi-stage rapid lifting device.

[0042] The outer sleeve of the multi-stage rapid lifting device 1 is fixed on the buried foundation 3, see Figure 8 . First-grade threaded disc 11 (see Figure 10 ) and first-stage sleeve 17 (see Figure 11 They are assembled together using bolt connections to form a primary assembly, see... Figure 12 The first-stage threaded disc 11 has a convex cross-section and is hollow in the middle. The outer side of the lower half is connected to the end of the first-stage sleeve 17 by bolts 26.

[0043] After the primary sleeve 17 and the primary threaded disc 11 are assembled, the four evenly distributed grooves 28 of the primary sleeve 17 and the four evenly distributed grooves 28 of the primary threaded disc 11 are aligned to form four grooves (see...). Figure 12 Connect the four recesses of the primary assembly to the four evenly distributed bosses 30 on the outer sleeve 16 (see...). Figure 13 This allows the primary assembly to be assembled with the outer sleeve 16. The four evenly distributed bosses 30 on the outer sleeve 16 guide the movement of the primary assembly (see...). Figure 9 (View from direction A).

[0044] Primary mandrel 22 (see) Figure 14 The primary threaded disc 11 and the first-stage threaded disc 11 are assembled together by two bearings 27, as shown. Figure 16 On the side of the primary spindle 22, there is a window for mounting the rolling elements (see...). Figure 16 (View A) A bearing 27 is installed between the primary spindle 22 and the primary threaded disc 11, and the primary spindle 22 and the primary threaded disc 11 can respectively serve as the outer ring and inner ring of the bearing 27. A cage for rolling elements is installed between them to form a bearing 27. Intermediate spindle 10 (see...) Figure 15Installed on a power source, the thread of the intermediate spindle 10 engages with the thread of the primary threaded disc 11, and the four evenly distributed grooves 28 of the intermediate spindle 10 engage with the four spindle bosses 30 of the primary spindle 22. Under the action of the rotating intermediate spindle and the two bearings, the primary spindle 10 can rotate around the primary threaded disc 11. The assembly of the remaining stages of the multi-stage rapid lifting device is the same as that of the first stage.

[0045] In one specific embodiment, the assembly is configured in five stages. The second stage assembly includes a secondary threaded disc 12, a secondary sleeve 18, and a secondary mandrel 23; the third stage assembly includes a tertiary threaded disc 13, a tertiary sleeve 19, and a tertiary mandrel 24; the fourth stage assembly includes a quaternary threaded disc 14, a quaternary sleeve 20, and a quaternary mandrel 25; and the fifth stage assembly is the last stage, which only includes a quaternary sleeve 21 and a quaternary mandrel 26.

[0046] When the intermediate spindle 10 rotates under the action of the power source, the first-stage assembly moves upward under the action of the threaded disc and the guiding action of the evenly distributed bosses on the outer sleeve, simultaneously driving the first-stage spindle 22 to move upward. The four spindle bosses 30 of the first-stage spindle 22 are inserted into the four evenly distributed grooves 28 of the intermediate spindle, so that the rotation of the intermediate spindle drives the first-stage spindle 22 to rotate together at the same speed. Similarly, the 29 threads of the first-stage spindle 22 can drive the second-stage assembly (assembled from the second-stage spindle 23 and the second-stage sleeve 18) to move upward, and so on, so that each stage of the assembly moves upward simultaneously, thereby achieving the function of rapid lifting and reaching the working state. The retraction process of the multi-stage rapid lifting device 1 is the reverse of the lifting process. Simply rotate the power source in the opposite direction, and each stage of the assembly can be retracted, and the device returns to its initial state. During the lifting and lowering process, the multi-stage rapid lifting device 1 can stop at any position within its stroke.

[0047] When the rapid lifting device is in its initial state, a concealed shielding device 2 is installed for the system to protect the safety of the system and personnel (e.g., Figure 5 and Figure 6 The concealment cover is mounted above the rapid lifting device. Two chains 33 are fixed below the cover assembly of the concealment cover, and these chains 33 are driven by sprockets 31 on the shaft 32 of the drive unit (see...). Figure 17 and Figure 18 This allows for the retraction and extension (expansion and retraction) of the cover plate assembly, enabling the opening and closing of the working channel of the multi-stage rapid lifting device. See [link / reference]. Figure 19 .

[0048] When the system needs to operate, the drive unit at the bottom of the concealment cover device 2, under the action of the power source, drives the sprocket 31 to rotate clockwise, retracting the cover assembly 4 to the right side and into the track. Figure 20The system reaches its working state. After the work is completed, the drive unit, under the action of the power source, drives the sprocket 31 to rotate counterclockwise, releasing the cover plate assembly, closing the working channel of the multi-stage rapid lifting device 1, and returning the multi-stage rapid lifting device 1 to its initial position. Figure 21 .

[0049] The buried foundation 3 is a reinforced concrete structure, which mainly provides a base for the installation of the multi-stage rapid lifting device 1 and an interface for the installation of the concealed cover device 2. The track of the concealed cover device is installed on the inner wall of the buried foundation. The buried foundation also provides storage space for the cover plate assembly 4 of the concealed cover device when the system is in operation.
