[0037] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] To solve the technical problems in the background art, the following azimuth adjustment device for radar testing is provided:

[0040] Combined with Figures 1 - 12As shown in the figure, an azimuth adjustment device for radar testing provided by the present invention includes a driving rod body 1, a driven rod body 2, and a vehicle body 9. A connection assembly 8 is fixedly installed on the loading surface of the vehicle body 9. The driving rod body 1 and the driven rod body 2 are respectively movably installed on the connection assembly 8. A main telescopic cylinder 6 is assembled inside the driving rod body 1 and the driven rod body 2, and the main telescopic cylinder 6 is in a diagonal bracing shape. A support assembly 5 that is mutually butted is assembled on the driving rod body 1 and the driven rod body 2. A driving assembly 3 is jointly and movably installed on the tops of the driving rod body 1 and the driven rod body 2. The ends of the driving rod body 1, the driven rod body 2, and the main telescopic cylinder 6 are all assembled and connected to the connection assembly 8 and the driving assembly 3 through a movable assembly 7. A rotating assembly 4 is fixedly installed on the top of the driving assembly 3. An antenna matrix assembly 10 is assembled on the top of the rotating assembly 4;

[0041] During this period, through the mutual combination of the diagonal bracing main telescopic cylinders 6 inside the driving rod body 1 and the driven rod body 2, the mechanism utilizes the traditional parallelogram linkage structure form. This structure not only has the characteristics of simple and compact structure, but also has a high lifting height, good reliability and stability. Through the operations of the support assembly 5 and the driving assembly 3, multiple limiting measures are respectively realized for the driving rod body 1, the driven rod body 2, and the rotating assembly 4. The hydraulic pins are locked when the deployment and retraction reach the position, ensuring the reliability and repeated positioning accuracy of the erection mechanism, ensuring that the pitching motion is within the stroke range. The driving assembly 3 and the rotating assembly 4 cooperate with each other, enabling the mechanism to perform continuous rotation functions, effectively saving installation space; and combining the mechanical locking mechanism and the electric limit switch on the vehicle body 9 to ensure transportation safety, and further ensuring the safety of erection / retraction and equipment use, enhancing the overall stability. And using the connection assembly 8 as the bottom installation structure of the mechanism and installing it close to the front of the vehicle body 1 can ensure the reasonable center of gravity of the overall mechanism, so as to avoid deformation, fracture or overturning when affected by wind force or external impact.

[0042] The driving assembly 3 includes an upper seat body 31, an upper seat body 32, a positioning component 33, and a driving machine 34; the rotating assembly 4 includes a support arm 41 and a rotating seat 42; the support assembly 5 includes a first support member 51, a limiting component 52, and a second support member 53; the connection assembly 8 includes a first mounting seat 82 and a second mounting seat 84. The loading surfaces of the vehicle body 9 are respectively and fixedly installed with the first mounting seat 82 and the second mounting seat 84. The first mounting seat 82 is movably connected to the bottom of the driven rod body 2, and the second mounting seat 84 is movably connected to the bottom of the driving rod body 1. A first support member 51 and a second support member 53 are respectively and fixedly installed on the driving rod body 1 and the driven rod body 2. The first support member 51 and the second support member 53 are triangular in shape. A mutually docking limiting component 52 is assembled on the first support member 51 and the second support member 53 together. The tops of the driving rod body 1 and the driven rod body 2 are fixedly installed with an upper seat body 31. The top of the upper seat body 31 is fixedly installed with a positioning component 33. The top of the positioning component 33 is fixedly installed with a rotating disk 32 for driving cooperation. The positioning component 33 is connected with a rotating seat 42 through the rotating disk 32. Support arms 41 are fixedly installed on both sides of the rotating seat 42, and the rotating seat 42 is assembled and connected with the antenna matrix assembly 10 through the support arms 41.

[0043] During this period, when performing the lifting operation, the main telescopic cylinder 6 can be started for operation. Under the movable hinge cooperation of the movable assembly 7, the driving rod body 1 and the driven rod body 2 are promoted to expand smoothly. And during the expansion, the first support member 51 and the second support member 53 on the driving rod body 1 and the driven rod body 2 will also move synchronously, prompting the first support member 51 and the second support member 53 to enter the docking state. When the driving rod body 1 and the driven rod body 2 reach the state of a parallelogram linkage structure between the driving rod body 1 and the driven rod body 2, when the main telescopic cylinder 6 and the first support member 51 and the second support member 53 reach the docking state synchronously, a stable triangular support structure is formed to complete the lifting action from 0 degrees to 90 degrees. At this time, the limiting component 52 can be started to lock the docking state of the first support member 51 and the second support member 53, and also ensure the stability of the driving rod body 1 and the driven rod body 2 during the support synchronously. When performing the rotation adjustment, the rotating seat 42 is driven by the driving machine 34 in combination with the positioning component 33, prompting the rotating seat 42 to drive the upper antenna assembly to rotate.

[0044] Embodiment 2

[0045] As Figure 1 and Figure 12 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0046] In this embodiment, a reinforcing component 11 is jointly assembled inside the active rod body 1 and the driven rod body 2. The reinforcing component 11 includes a reinforcing rod 111 and a support rod 112. The reinforcing rod 111 is jointly assembled inside the active rod body 1 and the driven rod body 2, and two groups of support rods 112 are fixedly installed inside the reinforcing rod 111, and the two groups of support rods 112 are cross-shaped.

[0047] During this period, the reinforcing component 11 is used as a connecting member between the rod bodies, and the two groups of support rods 112 are cross-connected, which not only increases the support strength of the reinforcing rod 111, but also further ensures the stability and load-bearing performance of the active rod body 1 and the driven rod body 2 during lifting.

[0048] In this embodiment, the positioning component 33 includes a hydraulic slide rail 331, a mounting plate 332, a first hydraulic pin 333, a stop block 334, and a pin hole 335. The mounting plate 332 is fixedly installed at the top of the upper seat body 31, the rotating disk 32 is fixedly installed on the mounting plate 332, the hydraulic slide rail 331 is fixedly installed on the mounting plate 332, the stop block 334 is fixedly installed at the bottom of the rotating seat 42, and the stop block 334 cooperates with the hydraulic slide rail 331. The first hydraulic pin 333 is fixedly installed on the mounting plate 332, and a pin hole 335 is provided at the bottom of the rotating seat 42, and the pin hole 335 and the first hydraulic pin 333 are inserted and matched with each other.

[0049] During this period, the hydraulic slide rail 331 and the stop block 334 cooperate with each other; the first hydraulic pin 333 and the pin hole 335 cooperate with each other;

[0050] When the device is reset, in order to ensure that the device can be reset to the initial state, the initial position of the sliding of the hydraulic slide rail 331 is used, that is, the hydraulic cylinder pushes the slider on the slide rail, prompting the slider to slide inward. At this time, the slider on the slide rail will be reset to the blocking state. When the rotating seat 42 rotates to the predetermined position, the stop block 334 at its bottom will be blocked by the slider on the slide rail, preventing the rotating seat 42 from rotating further, achieving a limiting effect;

[0051] Then the first hydraulic pin 333 operates, driving the pin at the end to insert into the pin hole 335, realizing the positioning of the rotating seat 42, locking the state of the rotating seat 42, and cooperating with the device to be reset.

[0052] In this embodiment, the rotating assembly 4 further includes a hinge cylinder 43, a movable shaft two 44, and a connecting head 45. One end inside the support arm 41 is butt-jointed and installed with the movable shaft two 44, and the other end inside the support arm 41 is butt-jointed and installed with the hinge cylinder 43. The end of the hinge cylinder 43 is butt-jointed and installed with the connecting head 45. The support arm 41 is assembled and connected with the antenna matrix assembly 10 through the movable shaft two 44 and the connecting head 45.

[0053] During this period, when the antenna matrix assembly 10 needs to be flipped and adjusted, it is completed by the articulated cylinder 43. The articulated cylinder 43 pushes the front end of the bottom of the antenna matrix assembly 10 at the front through the connector 45, while the rear end of the antenna matrix assembly 10 is movably connected to the support arm 41 through the movable shaft two 44. Therefore, when the front end of the antenna matrix assembly 10 is subjected to the driving force of the articulated cylinder 43, it will perform angle adjustment around the movable shaft two 44 as the movable point.

[0054] Embodiment Three

[0055] As Figures 1 - 12 shown, on the basis of the above embodiment, the present embodiment further gives the following content:

[0056] In this embodiment, the limiting component 52 includes a second hydraulic pin 521, a socket 522, a first fixing seat 523, a plugging block 524, and a second fixing seat 525. The first fixing seat 523 is fixedly installed on the inner side of the first support member 51, the socket 522 is fixedly installed on the first fixing seat 523, and a docking port 526 is provided on the socket 522. The second fixing seat 525 is fixedly installed on the inner side of the second support member 53, the plugging block 524 is fixedly installed on the second fixing seat 525, and the plugging block 524 is in docking cooperation with the first fixing seat 523. The second hydraulic pin 521 is fixedly installed on the socket 522, and the pin end of the second hydraulic pin 521 extends into the docking port 526 and is inserted and positioned with the plugging block 524.

[0057] During this period, when the device reaches the fully lifted state, in order to ensure stability during lifting, the state is locked through the limiting component 52 to ensure the stability of the device during operation;

[0058] When the device reaches the fully lifted state, docking occurs between the first support member 51 and the second support member 53, prompting the plugging block 524 to be within the docking port 526 in the socket 522. At this time, the second hydraulic pin 521 can be started, and the second hydraulic pin 521 will drive the pin at the end to insert into the docking port 526 along the trend, realizing the insertion and positioning of the plugging block 524 within the docking port 526.

[0059] In this embodiment, the connection assembly 8 further includes a lower seat body 81 and a lug 83. The lower seat body 81, which is connected to each other, is fixedly installed on the inner sides of the first mounting seat 82 and the second mounting seat 84. The bottom of the lower seat body 81 is fixedly connected to the loading surface of the vehicle body 9, and lugs 83 are fixedly installed on both sides of the second mounting seat 84.

[0060] During this period, the lower seat body 81 serves as a support member, which can not only carry the device, expand the support area, and ensure stability during support, but also through the lugs 83

[0061] In this embodiment, the movable component 7 includes a movable seat 71, a first movable part 72, and a second movable part 73. The first mounting seat 82 and the inner part of the upper seat body 31 are fixedly installed with the movable seat 71, and both ends of the main telescopic cylinder 6 are respectively assembled in the movable seat 71 on the first mounting seat 82 and the upper seat body 31. The first movable part 72 connected and assembled with the main telescopic cylinder 6 is butt - mounted in the movable seat 71. Both ends of the driving rod body 1 and the driven rod body 2 are respectively assembled and connected with the upper seat body 31, the first mounting seat 82, and the second mounting seat 84 through the second movable part 73. The second movable part 73 adopts the same operating principle as the first movable part 72.

[0062] The movable seat 71 realizes the movable connection with the connecting piece through the first movable part 72, prompting the driving rod body 1, the driven rod body 2, and the main telescopic cylinder 6 to complete the required angle adjustment.

[0063] During this period, the main telescopic cylinder 6 uses the first movable part 72 in the lower movable seat 71 as the activity point for support expansion. At that time, the driving rod body 1 and the driven rod body 2 will synchronously use the first movable part 72 at the top and bottom as the activity points for support expansion, realizing the formation of a parallelogram four - link structure form, and then achieving the required support and lifting effect.

[0064] In this embodiment, the first movable part 72 includes a mounting sleeve 721, a roller bearing 722, a first movable shaft 723, a locking nut 724, and a bushing 725. The inner part of the movable seat 71 is butt - mounted with the first movable shaft 723 through the bushing 725, and both ends of the first movable shaft 723 are butt - mounted with the locking nut 724. The mounting sleeve 721 is sleeved on the first movable shaft 723, and a roller bearing 722 is assembled between the mounting sleeve 721 and the first movable shaft 723. The mounting sleeve 721 is assembled and connected with the driving rod body 1 and the driven rod body 2. The articulated end of the main telescopic cylinder 6 is sleeved on the first movable shaft 723.

[0065] During this period, when the main telescopic cylinder 6 performs telescopic operation, the articulated end of the main telescopic cylinder 6 will synchronously push the movable seat 71 on the first movable shaft 723. At that time, when the driving rod body 1 and the driven rod body 2 are subjected to the acting force, angle changes will occur at both ends of them. At this time, the driving rod body 1 and the driven rod body 2 will rotate around the first movable shaft 723 through the roller bearing 722 in the mounting sleeve 721 and gradually expand due to the driving force of the cylinder body.

[0066] It prompts the formation of a parallelogram four - link structure form between the driving rod body 1 and the driven rod body 2, and then achieves the required support and lifting effect.

[0067] The conduction component 74 includes a baffle 741, a connecting rod 742, and an encoder 743. The inner side of the active rod body 1 is fixedly installed with a connecting rod 742 extending into the second mounting seat 84. The baffle 741 is fixedly installed on the connecting rod 742, and the encoder 743 is fixedly installed on the connecting rod 742 inside the baffle 741.

[0068] The encoder 743 can collect the motion information of the moving component, facilitating personnel to master the adjustment data of the device during regulation, such as angles, orientations, etc.

[0069] In this embodiment, the second fixed seat 31, the support arm 41, and the rotating seat 42 are all provided with hollow openings, and the hollow openings are strip-shaped. Four sets of fastening bolts are assembled on the rotating seat 42, and the rotating seat 42 is assembled and connected to the rotating disc 32 through the four sets of fastening bolts.

[0070] The hollow openings not only reduce the weight of the top of the mechanism but also can be used as observation windows, ensuring that general maintenance of the mechanism can be directly completed through the observation windows, increasing the convenience during operation;

[0071] And during maintenance, personnel can complete the maintenance and repair between the rotating disc 32 and the second fixed seat 31 by disassembling the fastening bolts.
