Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0027] Example 1, referring to Figure 1 The first embodiment of the present invention provides an antenna flipping support device, including a mounting component 100 and a control component 200.

[0028] The mounting assembly 100 includes a first support 101 and a second support 102, and a flip frame 103 rotatably disposed between the first support 101 and the second support 102. The flip frame 103 is made of metal profile frame screwed or welded. The flip frame 103 can also be made of composite material depending on the load size. It is provided with connection interfaces required for product installation. At the same time, it can be equipped with laser rangefinders, angle measuring instruments, and position measuring rulers as needed. Antennas that need to be electrically measured can be installed in the flip frame 103.

[0029] The control component 200 includes a drive motor 201 disposed on the first support member 101 and connected to the flipping frame 103, and an electromagnetic clutch 202 disposed between the drive motor 201 and the flipping frame 103. The drive motor 201 can drive the electromagnetic clutch 202 and the flipping frame 103 to rotate.

[0030] When the electromagnetic clutch 202 is energized, it can transmit force, causing the drive motor 201 to rotate the flip frame 103, thereby adjusting the electrical measurement angle of the antenna. When it is necessary to manually adjust the angle of the flip frame 103, simply de-energize the electromagnetic clutch 202 to disconnect the force transmission from the drive motor 201 to the flip frame 103, and the angle adjustment of the flip frame 103 can be manually controlled. Preferably, a protective shell is provided on the outside of the drive motor 201 and the electromagnetic clutch 202 to protect them.

[0031] Furthermore, a drive shaft 101a is rotatably mounted on the first support member 101, and a driven shaft 102a is rotatably mounted on the second support member 102; the ends of the drive shaft 101a and the driven shaft 102a are provided with locking blocks 104, and the flipping frame 103 is fixed between the two locking blocks 104; the electromagnetic clutch 202 is connected to the drive shaft 101a.

[0032] Example 2, refer to Figure 2 and Figure 3This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: both the first support member 101 and the second support member 102 include two sets of support portions 101b and a plurality of connecting rods 101c disposed between the two sets of support portions 101b; wherein the first support member 101 and the second support member 102 have approximately the same shape; wherein the support portion 101b includes two support frames 101b1 with their tops close to each other and a square frame 101b2 disposed between the two support frames 101b1.

[0033] Furthermore, each end of the flip frame 103 is provided with two fixing cylinders 103a, which are located on both sides of the locking block 104. The top of the square frame 101b2 is provided with two first pins 101b3 that cooperate with the fixing cylinders 103a. The flip frame 103 is rotated to keep it horizontal, and the first pins 101b3 are inserted into the fixing cylinders 103a to fix the flip frame 103. At this time, the flip frame 103 is in a horizontal state. Before adjusting the angle of the flip frame 103 during antenna electrical testing, the first pins 101b3 need to be pulled out.

[0034] The square frame 101b2 has a second pin 101b4 at its bottom that cooperates with the fixing cylinder 103a. When the flip frame 103 is in a vertical state, the second pin 101b4 can be inserted into the fixing cylinder 103a to fix the flip frame 103. At this time, the flip frame 103 is in a vertical state. Similarly, before adjusting the angle of the flip frame 103 during antenna electrical testing, the second pin 101b4 needs to be pulled out.

[0035] The purpose of setting horizontal and vertical states is that these are the most commonly used states, and these states are generally maintained for the longest time. After the mechanical connection is fixed, the power supply can be directly cut off, reducing the influence of electrical signals on the antenna test signals.

[0036] The remaining structure is the same as that in Example 1.

[0037] Example 3, referring to Figure 4 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the control component 200 further includes a moving member 203 and a lifting member 204. The moving member 203 includes a support base 203a connected to the bottom of the first support member 101 and the second support member 102, and a plurality of casters 203b disposed at the bottom of the support base 203a. The lifting member 204 is provided in a plurality of parts and is mounted on the support base 203a.

[0038] Furthermore, the support base 203a is also provided with multiple lifting components 204, which are made of bolts and are threadedly connected to the support base. By rotating the lifting components 204 to contact the ground, the support base 203a can be lifted up so that the caster wheel 203b leaves the ground, providing stable support for the support base 203a and preventing shaking during antenna electrical measurement, which would affect the stability and consistency of the measurement.

[0039] Furthermore, the support base 203a is provided with multiple telescopic grounding rods 105 and a support platform 106; the length of the telescopic grounding rods 105 can be adjusted, and the ends of the telescopic grounding rods 105 are connected to the bottom of the flip frame 103; the two ends of the telescopic grounding rods 105 are rotatably connected to the flip frame 103 and the support base 203a respectively. When the fixed cylinder 103a in the flip frame 103 is inserted with the first pin 101b3, the telescopic grounding rods 105 can be connected to the bottom of the flip frame 103. Multiple telescopic grounding rods 105 can provide multi-directional support for the flip frame 103, improve the rigidity of the flip frame 103, prevent collision vibration of the device caused by construction personnel's misoperation, and reduce secondary damage to the antenna caused by collision vibration; before adjusting the angle of the flip frame 103 during antenna electrical testing, the telescopic grounding rods 105 need to be disassembled and the first pin 101b3 needs to be pulled out.

[0040] The support platform 106 is rotatably connected to the support base 203a, and the support platform 106 is in contact with the side of the flip frame 103. When the fixed cylinder 103a in the flip frame 103 is inserted with the second pin 101b4, the side of the flip frame 103 contacts the support platform 106, and the support platform 106 supports the flip frame 103. Similarly, before adjusting the angle of the flip frame 103 during antenna electrical testing, the support platform 106 needs to be disassembled and the second pin 101b4 needs to be pulled out.

[0041] Furthermore, an accommodating space M is formed between the two support parts 101b; wherein an electrical control cabinet 205 is provided in the accommodating space M of the second support member 102. The electrical control cabinet 205 is electrically connected to the drive motor 201 and the automatic telescopic member 204e. The electrical control cabinet 205 is the brain control unit of the entire device, including an automated program control unit, a transformer regulation device, an electromagnetic control isolation device, a hand-cranked pulse transmitter, an LCD touch interface interaction device, and a program alarm lighting device. The built-in program can realize free control of the flipping frame 103.

[0042] Furthermore, the length of the connecting rod 101c of the first support member 101 is greater than the length of the connecting rod 101c of the second support member 102, and the toolbox can be placed in the accommodating space M of the first support member 101.

[0043] Example 4, refer to Figures 5-7 This is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that the lifting member 204 includes a mounting cylinder 204a disposed on the support base 203a, a support foot 204b slidably disposed in the mounting cylinder 204a, an air injection cylinder 204c disposed on the support base 203a, a piston portion 204d disposed in the air injection cylinder 204c, an automatic telescopic member 204e connected to the piston portion 204d, and a connecting pipe 204f disposed between the air injection cylinder 204c and the mounting cylinder 204a.

[0044] The automatic telescopic component 204e is made of an electric telescopic rod or a cylinder. The automatic telescopic component 204e can control the piston 204d to move in the air injection cylinder 204c, injecting air from inside the air injection cylinder 204c into the mounting cylinder 204a, thereby pushing out the support foot 204b. When the support foot 204b contacts the ground, it can lift the support base 203a, causing the caster wheel 203b to leave the ground, ensuring that the support base 203a is in a stable state, which is convenient for the electrical testing of the antenna.

[0045] Furthermore, the piston section 204d includes a piston column 204d1 slidably disposed in the air injection cylinder 204c and connected to the output end of the automatic telescopic member 204e, a first column 204d2 disposed in the air injection cylinder 204c, a second column 204d3 disposed at the end of the first column 204d2, and a piston rod 204d4 disposed at the end of the piston column 204d1; a connecting pipe 204f is disposed in the middle of the air injection cylinder 204c; the first column 204d2 and the second column 204d3 are slidably inserted into the piston column 204d1, and the piston column 204d1... A sliding groove is provided for sliding the first column 204d2 and the second column 204d3. The diameter of the second column 204d3 is larger than that of the first column 204d2, and the second column 204d3 is sealed to the piston column 204d1. An adjusting cylinder 204a1 is provided on the mounting cylinder 204a. The piston rod 204d4 passes through the air injection cylinder 204c and cooperates with the adjusting cylinder 204a1. The inner diameter of the adjusting cylinder 204a1 is smaller than that of the mounting cylinder 204a, and the inner diameter of the mounting cylinder 204a is smaller than that of the air injection cylinder 204c. A connecting pipe 204f is provided in the middle of the air injection cylinder 204c.

[0046] In the initial state, the support foot 204b is retracted in the mounting cylinder 204a, and the piston column 204d1 is located at the end of the air injection cylinder 204c. When the antenna is tested, the support base 203a is moved to the test position, and the piston part 204d is moved by the automatic telescopic component 204e, so that the air in the air injection cylinder 204c and the adjusting cylinder 204a1 is injected into the mounting cylinder 204a, and the support foot 204b extends out to contact the ground for support.

[0047] During operation, multiple automatic telescopic components 204e work synchronously, driving the piston column 204d1 to move in the air injection cylinder 204c. At the same time, the piston rod 204d4 moves in the adjusting cylinder 204a1, injecting air from the air injection cylinder 204c and the adjusting cylinder 204a1 into the mounting cylinder 204a, causing the support foot 204b to extend quickly. When the piston column 204d1 moves to cover the end of the connecting pipe 204f, the piston column 204d1 separates from the second column 204d3. The piston column 204d1 continues to move in the air injection cylinder 204c. At this time, the air in the air injection cylinder 204c overflows from the gap between the first column 204d2 and the piston column 204d1. When the middle of the piston column 204d1 coincides with the end of the connecting pipe 204f, the automatic telescopic component 204e stops working. At this time, multiple lifting components 204 raise the support base 203a.

[0048] Because multiple automatic telescopic components 204e work synchronously and multiple support legs 204b extend to the same length, the support base 203a may wobble when the ground is uneven. In this case, the automatic telescopic components 204e can be individually controlled to extend or retract, causing the piston rod 204d1 to move in the air injection cylinder 204c. Since the end of the connecting pipe 204f is covered, the air in the air injection cylinder 204c will not communicate with the mounting cylinder 204a, thus preventing large-scale extension or retraction of the support legs 204b. At the same time, the piston rod 204d4 moves in the adjusting cylinder 204a1 along with the movement of the piston rod 204d1. At this time, the adjusting cylinder 204a1 and the mounting cylinder 204a can communicate with each other. Since the inner diameter of the adjusting cylinder 204a1 is smaller than that of the mounting cylinder 204a, the support legs 204b can be controlled to extend or retract slightly, thereby enabling fine-tuning of the support base 203a to make it stable.

[0049] After the antenna electrical test is completed, multiple automatic telescopic components 204e are controlled to retract simultaneously, driving the piston rod 204d1 and piston rod 204d4 back to their initial positions, ensuring that the support leg 204b can extend the same length when the automatic telescopic component 204e works next time.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
