Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to a telescopic multi-stage lifting mechanism for radar loading. Background Technology

[0002] When loading radar, multi-stage elevators are usually used for long-stroke lifting. Multi-stage elevators can provide radar with a stable, accurate and reliable high-altitude working platform to overcome ground obstacles and expand the detection range.

[0003] Typically, multi-stage lifting platforms use bipolar screw drives to achieve large-stroke lifting. However, when the bipolar screw drives multiple tower sections for lifting, it will wear down over time. When the bipolar screw wears down, it may cause the multiple tower sections to lift asynchronously. If the wear is severe, it may lead to problems such as lifting jamming, structural deformation, and tower tilting, affecting the stable lifting of the radar. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention incorporates a drive mechanism and a connecting mechanism. The drive mechanism enables the overall lifting and lowering of the elevator body, and its higher compression ratio allows for multi-stage lifting. While ensuring sufficient lifting height, it reduces the height occupied during retraction, facilitating the movement of loading vehicles. The connecting mechanism connects lifting cylinders one, two, three, four, and five. Lifting relies entirely on the drive and connecting mechanisms, eliminating the need for gravity-based retraction of individual tower sections and preventing accidents such as jamming. Furthermore, lubrication and detection components are installed between lifting cylinders one, two, three, four, and five. These components ensure proper lubrication and monitor the synchronicity of lifting and lowering, providing feedback on wear based on detected height differences, thus facilitating maintenance and repair.

[0020] This invention incorporates a drive mechanism. When the main body of the elevator is raised or lowered, the drive screw is rotated to drive the first telescopic cylinder to perform a first-stage lifting motion. Simultaneously, the second telescopic cylinder performs a second-stage lifting motion. Through these two stages of lifting, the overall lifting motion of the elevator body is completed. This results in a larger compression ratio for the elevator body, enabling multi-stage lifting functions. It ensures the height of the elevator while reducing the height occupied during retraction.

[0021] This invention, by setting up a connecting mechanism, utilizes fixed pulley one, fixed pulley two, and fixed pulley three in conjunction with connecting wire rope one, connecting wire rope two, and connecting wire rope three to achieve the connection between lifting cylinder one, lifting cylinder two, lifting cylinder three, lifting cylinder four, and lifting cylinder five. During lifting, the entire lifting body of the elevator can be lifted and lowered by relying on the drive mechanism and the connecting mechanism, without relying on the gravity of the equipment body itself to recover individual tower sections, thus preventing accidents such as individual tower sections getting stuck.

[0022] This invention, through the configuration of detection components and levers, and the cooperation of a drive mechanism and a connecting mechanism, enables the overall lifting of the elevator body. During the lifting of lifting cylinders two, three, four, and five within the elevator body, the levers move synchronously with these cylinders. When the levers move, they contact and press the corresponding pressing blocks, triggering the corresponding trigger switches. Each trigger switch is activated by an external PLC controller, which controls an external dot counter to count once and simultaneously records the recording time at that point. When lifting cylinders two, three, four, and five all move synchronously, they should simultaneously mark the point when they reach the same height. If they do not move synchronously, it indicates wear in the drive mechanism components. The failure of synchronous movement of lifting cylinders two, three, four, and five results in discrepancies in the feedback dot marking results. The feedback dot marking results reflect the height difference between lifting cylinders two, three, four, and five, thus indicating the wear condition.

[0023] This invention incorporates a lubrication assembly. During the lifting of lifting cylinders two, three, four, and five, a lever moves synchronously. The lever actuates a partition block, causing it to rotate. This rotation presses against a pressure plate, which, under downward force, moves downward and drives a sealing plug downward via a pressure rod. Spring three is compressed, separating the sealing plug from the closing ring. Lubricating oil from the oil reservoir is injected into the lubrication sleeve through a bottom pipe, connecting pipe, and oil guide pipe. When connecting wire ropes one, two, and three pass through the lubrication sleeve, they come into contact with the lubricating oil, achieving lubrication. This allows for small-volume, multiple lubrication of connecting wire ropes one, two, and three, reducing friction during lifting and minimizing wear and tear. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figures 1-9A telescopic multi-stage lifting mechanism for radar mounting includes a lifting body 1 for mounting a radar antenna. The lifting body 1 can be mounted on a loading vehicle. The lifting body 1 includes a first lifting cylinder 11, which is fixedly mounted on the loading vehicle. A second lifting cylinder 12 is slidably mounted inside the first lifting cylinder 11 via a guide rail. A third lifting cylinder 13 is slidably mounted inside the second lifting cylinder 12 via a guide rail. The lifting cylinder 11 has a lifting cylinder 4 14 slidably installed inside the lifting cylinder 3 13 via a guide rail. The lifting cylinder 4 14 also has a lifting cylinder 5 15 slidably installed inside the lifting cylinder 4 14 via a guide rail. The lifting cylinder 11 has a drive mechanism 2 inside, which drives the lifting cylinders 2 12, 3 13, 4 14, and 5 15 to rise and fall. The lifting cylinder 11 also has two sets of connecting mechanisms 3 symmetrically arranged inside, which are used for lifting... The interconnection between lifting cylinder 11, lifting cylinder 212, lifting cylinder 313, lifting cylinder 414, and lifting cylinder 515 utilizes the cooperation of drive mechanism 2 and connecting mechanism 3 to achieve the overall lifting of the lifting platform body 1, improving safety. Two sets of fixing brackets 4 are symmetrically fixed on both sides of the interior of lifting cylinders 11, 212, 313, and 414. Lubrication components are installed on the fixing brackets 4, which can be used to lubricate the connecting mechanism 3, ensuring its normal operation and preventing insufficient lubrication of parts within the connecting mechanism 3. Wear and tear affecting usability is a concern. An inspection component is installed on the intermediate frame 41 to detect whether the lifting cylinders 12, 13, 14, and 15 are lifting synchronously. If there is a height difference between these cylinders, and this difference exceeds a set value (this value is manually set; exceeding the set value indicates that the equipment wear exceeds the normal operating range), then the equipment is experiencing severe wear and requires timely maintenance and parts replacement.With a drive mechanism 2 and a connecting mechanism 3, the drive mechanism 2 enables the overall lifting and lowering movement of the elevator body 1. The drive mechanism 2 has a larger compression ratio and can achieve multi-stage lifting functions. While ensuring the rising height, it reduces the height occupied during retraction, making it easier for the loading vehicle to move. At the same time, the connecting mechanism 3 enables the connection between lifting cylinder 11, lifting cylinder 22, lifting cylinder 33, lifting cylinder 44, and lifting cylinder 515. Lifting and lowering rely on the drive mechanism 2 and the connecting mechanism 3, eliminating the need to rely on the weight of the equipment body to retract individual tower sections, thus preventing accidents such as individual tower sections getting stuck. In addition, lubrication components and detection components are set between lifting cylinder 11, lifting cylinder 22, lifting cylinder 33, lifting cylinder 44, and lifting cylinder 515. While ensuring normal lubrication of the components, it can monitor the lifting synchronization between lifting cylinder 11, lifting cylinder 22, lifting cylinder 33, lifting cylinder 44, and lifting cylinder 515, and provide feedback on the wear of the equipment based on the detected height difference, so as to facilitate maintenance and repair by the staff.

[0036] As an optimized solution for a telescopic multi-stage lifting mechanism for radar loading according to the present invention, the driving mechanism 2 includes a driving screw 25, which is rotatably installed at the bottom of the inner wall of the lifting cylinder 11. The driving screw 25 is driven by a servo motor, which is electrically connected to an external PLC controller. An outer sleeve 21 is fixedly installed at the bottom of the inner wall of the lifting body 1. A telescopic cylinder 22 is movably installed between the lifting body 1 and the outer sleeve 21. The telescopic cylinder 22 is threadedly connected to the driving screw 25, and the driving screw 25 is slidably connected to the outer sleeve 21. The driving screw 25 can move up and down between the driving screw 25 and the outer sleeve 21. An inner sleeve 24 is fixedly installed inside the telescopic cylinder 22, and the inner sleeve 24 is sleeved with the driving screw 25. The outer circular wall surface of the inner sleeve 24... The system has an external thread. A second telescopic cylinder 23 is provided between the inner sleeve 24 and the first telescopic cylinder 22. The second telescopic cylinder 23 is threadedly connected to the inner sleeve 24 and is slidably installed inside the first telescopic cylinder 22. The top of the second telescopic cylinder 23 is fixedly connected to the fifth lifting cylinder 15. By providing a drive mechanism 2, when the lifting body 1 is raised or lowered, the drive screw 25 is controlled to rotate. When the drive screw 25 rotates, it drives the first telescopic cylinder 22 to perform a first-stage lifting motion. Simultaneously, the second telescopic cylinder 23 performs a second-stage lifting motion. Through two stages of lifting, the overall lifting motion of the lifting body 1 is completed, so that the lifting body 1 has a larger compression ratio and can realize multi-stage lifting function, while ensuring the rising height and reducing the height occupied during retraction.

[0037] As an optimized solution for a telescopic multi-stage lifting mechanism for radar loading according to the present invention, the connecting mechanism 3 includes a fixed pulley 31, which is disposed on one side of the outer wall of the second lifting cylinder 12 and rotatably mounted on the second lifting cylinder 12. A fixed pulley 32 is disposed on one side of the outer wall of the third lifting cylinder 13 and rotatably mounted on the third lifting cylinder 13. A fixed pulley 33 is disposed on one side of the outer wall of the fourth lifting cylinder 14 and rotatably mounted on the fourth lifting cylinder 14. A connecting steel wire rope 34 is disposed on the fixed pulley 31 and is movably connected to the fixed pulley 31. The two ends of the connecting steel wire rope 34 are fixedly connected to the first lifting cylinder 11 and the third lifting cylinder 13, respectively. A connecting steel wire rope 35 is disposed on the fixed pulley 32 and is movably connected to the fixed pulley 32. The two ends of the connecting wire rope 35 are fixedly connected to the lifting cylinder 12 and the lifting cylinder 14 respectively. The fixed pulley 33 is equipped with a connecting wire rope 36, which is movably connected to the fixed pulley 33. The two ends of the connecting wire rope 36 are fixedly connected to the lifting cylinder 13 and the lifting cylinder 5 15 respectively. By setting up the connecting mechanism 3, the connection between the lifting cylinder 11, lifting cylinder 212, lifting cylinder 333 and the connecting wire rope 34, connecting wire rope 25 and connecting wire rope 36 can be realized by using the fixed pulley 11, fixed pulley 22 and fixed pulley 33 in conjunction with the connecting wire rope 34, connecting wire rope 235 and connecting wire rope 36. During lifting, the lifting of the entire lifting machine body 1 can be realized by relying on the drive mechanism 2 and the connecting mechanism 3, without relying on the gravity of the equipment body to recover individual tower sections, thus preventing accidents such as individual tower sections getting stuck.

[0038] As an optimized solution for a telescopic multi-stage lifting mechanism for radar loading according to the present invention, the detection component includes an intermediate frame 41, which is fixedly installed on the outer wall of a fixed frame 4. A rotating cylinder 42 is rotatably installed inside the intermediate frame 41. The rotating cylinder 42 has a hollow structure and is rotatably installed inside the intermediate frame 41 via a rotating shaft. A torsion spring 45 is sleeved on the rotating shaft used to connect the rotating cylinder 42. Two partition blocks 421 are fixedly installed on the outer wall of the rotating cylinder 42. The partition blocks 421 are trapezoidal blocks. Two pressing blocks 422 are provided on the outer wall of the rotating cylinder 42. The pressing blocks 422 are slidably installed on the outer wall of the rotating cylinder 42 and extend into the interior of the rotating cylinder 42. A pressing block 422 extends into the interior of the rotating cylinder 42 and is fixedly installed on one side with a pressing block 423. The pressing block 423 is slidably installed inside the rotating cylinder 42. Two springs 424 are fixedly installed between the pressing block 423 and the rotating cylinder 42. The two ends of the springs 424 are fixedly connected to the inner wall of the rotating cylinder 42 and the outer wall of the pressing block 423, respectively. Trigger switches 425 are fixedly installed inside the rotating cylinder 42 at positions corresponding to the two pressing blocks 423. The trigger switches 425 are electrically connected to an external PLC controller. Multiple sets of toggle blocks 37 are fixedly installed at equal intervals on both sides of the outer walls of the lifting cylinders 12, 13, 14, and 15. The number of toggle blocks 37 depends on the lifting cylinder. The heights of lifting cylinders 12, 13, 14, and 15 are set. With the aid of a detection component and a lever 37, the entire lifting body 1 can be raised and lowered via the drive mechanism 2 and the connecting mechanism 3. During the raising and lowering of lifting cylinders 12, 13, 14, and 15, lever 37 moves synchronously with them. When lever 37 moves, it contacts and presses the corresponding pressing block 422, triggering the corresponding trigger switch 425. When trigger switch 425 is triggered once, the external PLC controller controls the external devices. The dot counter counts once and records the recording time at that point. When lifting cylinders 2 (12), 3 (13), 4 (14), and 5 (15) all rise and fall synchronously, they should mark the point synchronously when they reach the same height. If they do not rise and fall synchronously, it indicates that the components in drive mechanism 2 are worn. If lifting cylinders 2 (12), 3 (13), 4 (14), and 5 (15) fail to rise and fall synchronously, there will be a discrepancy in the feedback dot marking results. The feedback dot marking results reflect the height difference between lifting cylinders 2 (12), 3 (13), 4 (14), and 5 (15) to reflect the wear condition.

[0039] As an optimized solution for a telescopic multi-stage lifting mechanism for radar loading according to the present invention, the lubrication assembly includes an oil storage box 43. Two sets of oil storage boxes 43 are symmetrically fixedly installed on both sides of the outer wall of the fixed frame 4. The oil storage box 43 stores lubricating oil inside. An oil injection pipe is connected to the top of the oil storage box 43, and lubricating oil can be added into the oil storage box 43 through the oil injection pipe. Two sets of cams 44 are rotatably installed on the fixed frame 4. The cams 44 are fixedly connected to the rotating shaft for connecting the rotating cylinder 42. When the rotating cylinder 42 rotates, it can drive the cams 44 to rotate synchronously. A pressure plate 431 is slidably installed on the top of the oil storage box 43. The pressure plate 431 can lift the top of the oil storage box 43. The cam 44 rotates and contacts the pressure plate 431, pressing it downwards. A downward pressing shaft 434 is fixedly installed at the bottom of the pressure plate 431. A connecting cylinder 433 is fixedly installed on the oil reservoir 43 at a position corresponding to the downward pressing shaft 434. The downward pressing shaft 434 is slidably installed inside the connecting cylinder 433. A second spring 432 is fixedly installed inside the connecting cylinder 433, with one end of the spring 432 fixedly connected to the pressure plate 431. A pressing rod 492 is fixedly installed at the bottom of the downward pressing shaft 434. Two bottom tubes 49 are fixedly installed at the bottom of the inner wall of the oil reservoir 43, and connecting tubes 48 are fixedly installed on both bottom tubes 49. An external fixing sleeve 46 is provided on the outside of the oil box 43. An external connecting sleeve 47 is fixedly installed inside the fixing sleeve 46. The external connecting sleeve 47 is fixedly connected to two connecting pipes 48. The two connecting pipes 48 extend into the interior of the external connecting sleeve 47. A lubrication sleeve 471 is installed inside the external connecting sleeve 47. The lubrication sleeve 471 is made of sponge material. Connecting wire rope 1 34, connecting wire rope 2 35, and connecting wire rope 3 36 pass through the interior of the lubrication sleeve 471 and extend to the exterior of the lubrication sleeve 471. Two oil guide pipes 472 are fixedly installed between the lubrication sleeve 471 and the external connecting sleeve 47. The oil guide pipes 472 are circular pipes. Circular outlets are evenly opened on the inner circular wall of the oil guide pipes 472. The oil hole and the oil guide pipe 472 are fixedly connected to two connecting pipes 48. The lubricating oil inside the oil storage box 43 can be injected into the lubrication sleeve 471 through the bottom pipe 49, the connecting pipe 48 and the oil guide pipe 472. A sealing ring 493 is fixedly installed inside the bottom pipe 49. The sealing ring 493 has a circular structure. A sealing plug 491 is slidably installed inside the sealing ring 493. The sealing plug 491 has a frustum structure. The outer wall of the sealing plug 491 contacts the inner wall of the sealing ring 493. The sealing plug 491 is fixedly connected to the extrusion rod 492. A spring 494 is fixedly installed inside the bottom pipe 49. One end of the spring 494 is fixedly connected to the bottom of the sealing ring 493.With the lubrication assembly in place, the lever 37 moves synchronously as the lifting cylinders 12, 13, 14, and 15 rise and fall. Lever 37 causes the partition block 421 to rotate, pressing the pressure plate 431. The pressure plate 431, subjected to a downward force, moves downward and drives the sealing plug 491 downward via the compression rod 492. The spring 494 is compressed, separating the sealing plug 491 from the closing ring 493. The lubricating oil inside the oil reservoir 43 flows through the bottom pipe 4... 9. Connecting pipe 48 and oil guide pipe 472 are injected into lubrication sleeve 471. When connecting wire rope 1 34, connecting wire rope 2 35, and connecting wire rope 3 36 move through the inside of lubrication sleeve 471, they can come into contact with the lubricating oil drawn into lubrication sleeve 471 to complete lubrication. This allows for small-volume, multiple lubrication of connecting wire rope 1 34, connecting wire rope 2 35, and connecting wire rope 3 36, reducing friction during lifting and reducing wear and tear on connecting wire rope 1 34, connecting wire rope 2 35, and connecting wire rope 3 36.

[0040] When in use, the lifting cylinder 11 is installed on the loading vehicle, and the radar antenna is installed on the top of the lifting cylinder 5 15. After assembly, lifting operations can be performed.

[0041] During lifting and lowering, the servo motor drives the drive screw 25 to rotate, and the drive screw 25 rotates to drive the telescopic cylinder 1 22 to move up and down. Simultaneously, the inner sleeve 24 rotates, and the telescopic cylinder 23 moves up and down. The telescopic cylinder 1 22 and the telescopic cylinder 2 23 move up and down in sync, and with the help of the connecting wire rope 1 34, connecting wire rope 2 35 and connecting wire rope 3 36, the lifting cylinder 2 12, lifting cylinder 3 13, lifting cylinder 4 14 and lifting cylinder 5 15 are driven to move up and down.

[0042] When lifting cylinders 2 (12), 3 (13), 4 (14), and 5 (15) rise and fall, the toggle block 37 rises and falls synchronously. During the up-and-down movement of the toggle block 37, it can contact and squeeze the corresponding pressing block 422. When the pressing block 422 is squeezed once, the pressing block 423 presses and triggers the corresponding trigger switch 425. When the trigger switch 425 is pressed and triggered once, the external PLC controller controls the external dot counter to start a dot counting and records the time at that point. 4. After the lifting cylinder 15 has finished lifting, compare the timing of multiple points. If the lifting cylinders 12, 3, 4, and 5 are lifting synchronously, then when the lifting cylinders 12, 3, 4, and 5 are lifting the same height, the points should be marked synchronously. If there is a height difference between the lifting cylinders 12, 3, 4, and 5, there will be a time difference in the marking. If the time difference is within the acceptable range, no operation is required. If the time difference exceeds the acceptable range, manual maintenance or replacement of parts is required.

[0043] When lifting cylinders 12, 13, 14, and 15 rise and fall, the lever 37 rises and falls synchronously. When the lever 37 moves to the rotating cylinder 42, it contacts and presses the partition block 421, causing the rotating cylinder 42 to rotate. Each rotation of the rotating cylinder 42 drives the cam 44 to rotate once. When the cam 44 rotates, it presses the pressure plate 431 and drives the pressure plate 431 to move downward. When the pressure plate 431 moves downward, it drives the lower pressure shaft 434 and the pressure rod 492 to move downward and drives the sealing plug 491 to move downward. The sealing plug 491 moves and separates from the closing ring 493. At this time, the lubricating oil inside the oil storage box 43 is injected into the lubrication sleeve 471 through the bottom pipe 49, the connecting pipe 48, and the oil guide pipe 472. The lubrication sleeve 471 absorbs the lubricating oil. When the connecting wire rope 34, the connecting wire rope 35, and the connecting wire rope 36 move inside the lubrication sleeve 471, they can come into contact with the lubricating oil to complete the lubrication.

[0044] After the rotating drum 42 rotates once, the oil circuit is opened for one oil guiding lubrication. When the toggle block 37 rises and falls and no longer contacts the separator block 421, the rotating drum 42 rotates and resets under the action of the torsion spring 45. When the toggle block 37 at the next position moves to the rotating drum 42, the rotating drum 42 rotates again and performs the next oil guiding lubrication operation. During the rising and falling of the second lifting drum 12, the third lifting drum 13, the fourth lifting drum 14 and the fifth lifting drum 15, multiple oil guiding operations can be performed to complete the small number of multiple lubrication operations of the connecting wire rope 1 34, the connecting wire rope 2 35 and the connecting wire rope 3 36.
