Description

Technical Field

[0001] This invention belongs to the field of optical path alignment and calibration measurement technology, specifically relating to an infrared measuring instrument for optical path alignment and calibration and its usage method. Background Technology

[0002] An infrared measuring instrument for optical path alignment and calibration is a high-precision guiding instrument used for the installation, debugging, and calibration of precision optical systems. It emits a highly collimated infrared laser beam to form a stable reference line in space, used to accurately calibrate the collinearity and relative positional relationships of optical components such as lenses, mirrors, and detectors. It can achieve micron-level angular and straightness alignment and is widely used in the assembly of laser communication equipment, ground calibration of aerospace remote sensors, optical path construction of large scientific devices, and calibration of precision motion axes in high-end manufacturing.

[0003] In existing technologies, the standard operating procedure for infrared measuring instruments used for optical path alignment and calibration includes: preparation, instrument setup and leveling, coordinate system orientation, measurement or stakeout operations, data verification, and instrument packing. However, the following problems exist in actual use: First, after the instrument is leveled, the leveling screws are easily touched by backpacks, clothing, or the surveyor's knees, causing the bubble to shift, which in turn leads to distortion of horizontal angle measurements, errors in coordinate calculations, and inaccurate elevation transfer, resulting in deviation of stakeout points or inaccurate data collection, seriously damaging the reliability of measurement results; Second, on soft ground or under prolonged load, the threaded joints of the leveling screws may undergo slight plastic deformation or slippage, causing the instrument to slowly sink. During long-term monitoring tasks, this can easily be misjudged as a false displacement of the monitoring target, interfering with the judgment of the true position and orientation of optical components, posing a safety hazard. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention provides an infrared measuring instrument for optical path alignment and calibration, and its usage method. By setting an anti-settlement component, the instrument achieves precise leveling and rigid locking, preventing slow sinking caused by deformation of the threaded pair. By setting a safety component, the adjustment operation end is physically isolated after leveling, preventing accidental contact from damaging the leveling state.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] This invention first provides an infrared measuring instrument for optical path alignment and calibration, including a receiving block, an anti-settlement component, a safety component, a placement platform, and the main body of the infrared measuring instrument. The anti-settlement component is disposed between the upper surface of the receiving block and the placement platform, and includes a rotating screw, a worm gear turning block, a worm, a rotating rod, a gear, a rack, an abutment block, and a threaded receiving plate. The bottom end of the rotating screw is rotatably installed inside the receiving block, and the worm gear turning block is fixedly installed at the bottom end of the rotating screw. The rotating rod is rotatably installed on the upper surface of the receiving block and fixedly connected to the worm. The worm meshes with the worm gear turning block. The gear is fixed to the outer periphery of the rotating rod and meshes with the rack. The abutment block is fixedly installed on the upper surface of the rack. The threaded receiving plate is threadedly connected to the outer surface of the rotating screw and fixedly connected to the placement platform. The lower surface of the placement platform abuts against the upper surface of the abutment block. The safety component is disposed on the upper surface of the receiving block and is arranged around the adjustment and operation end of the anti-settlement component, and its protective plate is liftable. The main body of the infrared measuring instrument is mounted on the placement platform.

[0007] Furthermore, the anti-settlement component is provided in multiple sets, and the multiple sets of anti-settlement components are evenly arranged circumferentially along the upper surface of the receiving block.

[0008] Furthermore, the safety component includes a protective plate, a compression spring, and a telescopic rod; the upper surface of the receiving block has an internal receiving groove, and the protective plate is vertically and flexibly positioned in the receiving groove by means of the compression spring and the telescopic rod. The bottom ends of the compression spring and the telescopic rod are fixedly connected to the bottom end of the receiving groove, and the top ends are fixedly connected to the lower surface of the protective plate.

[0009] Furthermore, a push-button groove is provided at the top of the protective plate.

[0010] Furthermore, a rectangular block is fixedly installed on the outer ring surface of the protective plate; a snap-fit ​​block is fixedly installed on the upper surface of the receiving block, and the rectangular block and the snap-fit ​​block engage when the protective plate moves down.

[0011] Furthermore, a self-locking hinge seat is fixedly installed on the lower surface of the receiving block, a telescopic bracket is installed at the hinge of the self-locking hinge seat, and a placement block is fixedly installed at the bottom end of the telescopic bracket.

[0012] Furthermore, the infrared measuring instrument for optical path alignment and calibration also includes a placement frame, an adjustment knob, and an operator; the placement frame is fixedly installed on the upper surface of the placement platform, the main body of the infrared measuring instrument is located inside the placement frame, the operator is located on the front of the placement frame, and the adjustment knob is located on the left side of the placement frame.

[0013] This invention also provides a method for using an infrared measuring instrument for optical path alignment and calibration, which is implemented using the aforementioned infrared measuring instrument and includes the following steps:

[0014] S1. Support the instrument at the measurement station and perform rough leveling;

[0015] S2. The rotating rod of the rotating anti-settlement component drives the rotating screw through the transmission of the worm and the worm wheel screwing block, which drives the threaded receiving plate and the placement platform to rise and fall, thus completing the precise leveling of the infrared measuring instrument body.

[0016] S3. Continue to rotate the rotating rod to drive the gear to mesh with the rack and move horizontally, so that the abutting block at the top of the rack abuts against the bottom surface of the placement platform to form a rigid auxiliary support;

[0017] S4. Press down the protective plate of the safety component to move it down and lock it in place. The protective plate remains in a sunken state, forming a physical barrier around the operating end of the rotating rod.

[0018] S5. The measurement operation is completed by controlling the main body of the infrared measuring instrument;

[0019] S6. After the operation is completed, release the lock of the protective plate to reset it, then rotate the rotating rod in the opposite direction to release the abutment block and collect the instrument.

[0020] The present invention has the following beneficial effects:

[0021] This invention incorporates an anti-settlement component, consisting of three sets evenly arranged circumferentially. Precise lifting and lowering of the placement platform is achieved through the meshing transmission of a worm gear and worm wheel cranking block. This transmission method possesses self-locking characteristics, effectively resisting reverse forces and preventing accidental loosening. A gear-driven rack ensures rigid contact between the abutment block and the placement platform, creating an auxiliary load-bearing path independent of the threaded pair. This eliminates the slow sinking of the instrument caused by plastic deformation or slippage of the threaded pair, ensuring the stability of the station's elevation and horizontal reference in soft ground or long-term monitoring missions. This provides a reliable data foundation for precision engineering such as deformation monitoring.

[0022] This invention utilizes a liftable protective plate within its safety components. After the instrument is leveled, it can be locked by pressing down. The locking design of its rectangular block and latching block is stable and reliable. When the protective plate is raised, it effectively prevents accidental contact with backpacks, knees, etc., avoiding measurement accidents caused by bubble displacement due to collisions. When the protective plate is lowered, the adjustment operation end is exposed, facilitating leveling operations. It seamlessly connects with the locking operation of the anti-settlement components, reducing quality risks caused by human error, minimizing repeated checks and rework time, and improving the overall efficiency and safety of field measurements.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 7 This embodiment provides an infrared measuring instrument for optical path alignment and calibration, including a receiving block 1, an anti-settling component 5, a safety component 6, a placement platform 7, a placement rack 8, an infrared measuring instrument body 9, an adjustment knob 10, and an operator 11.

[0036] A self-locking hinge seat 2 is fixedly installed on the lower surface of the receiving block 1. A telescopic bracket 3 is installed at the hinge of the self-locking hinge seat 2, and a placement block 4 is fixedly installed at the bottom of the telescopic bracket 3. The telescopic bracket 3 is used to support the entire instrument, and the self-locking hinge seat 2 is used to realize the rough leveling operation of the instrument.

[0037] The anti-settlement component 5 consists of three sets, which are evenly arranged circumferentially between the receiving block 1 and the placement platform 7 along the upper surface of the receiving block 1. They are used to drive the placement platform 7 to rise and fall to achieve precise leveling, and after leveling, they form a rigid contact with the placement platform 7 to prevent the instrument from slowly sinking.

[0038] The safety component 6 is disposed on the upper surface of the receiving block 1 and is arranged around the adjustment operation end of the three sets of anti-settlement components 5. The safety component 6 includes a liftable protective plate 602. When the protective plate 602 is raised, it forms a physical barrier to prevent accidental contact. When it is lowered, it exposes the adjustment operation end for operation.

[0039] The placement platform 7 is supported above the receiving block 1 by three sets of anti-settlement components 5. A placement frame 8 is fixedly installed on the upper surface of the placement platform 7, the infrared measuring instrument body 9 is located inside the placement frame 8, the operator 11 is located on the front of the placement frame 8, and the adjustment knob 10 is located on the left side of the placement frame 8 for controlling the position adjustment of the infrared measuring instrument body 9.

[0040] Through the above structure, the anti-settlement component 5 and the safety component 6 work together between the receiving block 1 and the placement platform 7: the anti-settlement component 5 achieves precise leveling and settlement locking of the instrument, and the safety component 6 provides protection for the adjustment operation end after leveling and locking. Together, they ensure the reference stability and operational safety of the instrument in long-term monitoring or complex operating environments.

[0041] Furthermore, such as Figure 4 , Figure 5As shown, the anti-settlement assembly 5 consists of three sets, all with identical structures, evenly arranged circumferentially between the receiving block 1 and the placement platform 7 along the upper surface of the receiving block 1. The anti-settlement assembly 5 includes a rotating screw 501, a worm gear turning block 502, a worm 503, a rotating rod 504, a limiting block 505, a gear 506, a rack 507, an abutment block 508, and a threaded receiving plate 509. The bottom end of the rotating screw 501 is rotatably mounted inside the receiving block 1, and the worm gear turning block 502 is fixedly mounted on the outer surface of the bottom end of the rotating screw 501. The limiting block 505 is fixedly mounted on the upper surface of the receiving block 1, and the rotating rod 504 is rotatably mounted inside the limiting block 505. One end of the rotating rod 504 is fixedly connected to one end of the worm 503, and the worm 503 meshes with the outer surface of the worm gear turning block 502. The gear 506 is fixedly installed on the outer periphery of the rotating rod 504. The gear 506 meshes with the rack 507, and an abutment block 508 is fixedly installed on the upper surface of the rack 507. The threaded receiving plate 509 is threadedly connected to the outer surface of the rotating screw 501. One side of the threaded receiving plate 509 is fixedly connected to the placement platform 7, and the lower surface of the placement platform 7 abuts against the upper surface of the abutment block 508.

[0042] Through the above structure, the anti-settlement component 5 transmits the adjustment force precisely through the meshing transmission of the worm gear turning block 502 and the worm 503. When the rotating rod 504 is driven, the worm 503 drives the worm gear turning block 502 to rotate, which in turn drives the rotating screw 501 to rotate. This causes the threaded receiving plate 509 to move the placement platform 7 up and down to precisely adjust its height, effectively preventing the measurement accuracy of the infrared measuring instrument from being affected by the settlement of the placement platform 7, and ensuring the accuracy of the measurement data. During the rotation of the rotating rod 504, the gear 506 drives the rack 507 to move, causing the abutment block 508 to move accordingly and abut against the placement platform 7. This creates a rigid abutment between the abutment block 508 and the bottom surface of the placement platform 7, preventing the placement platform 7 from shaking or moving accidentally during the measurement process, further ensuring the stability of the measurement. The meshing of the worm 503 and the worm wheel turning block 502 has a self-locking characteristic. When the height of the placement platform 7 is adjusted by rotating the rod 504, the worm wheel turning block 502 will not rotate on its own without external force driving the rotating rod 504. This ensures that the position of the rotating screw 501 and the threaded receiving plate 509 is fixed, and the height of the placement platform 7 will not change. This prevents reverse rotation, ensures the stability of the locked state, enhances the safety of the entire measuring device during use, and avoids measurement accidents caused by unexpected changes in the height of the placement platform 7.

[0043] Furthermore, such as Figure 6 , Figure 7As shown, the safety component 6 includes a protective plate 602, a compression spring 603, a telescopic rod 604, a rectangular block 606, and a locking block 607. The upper surface of the receiving block 1 has an internal receiving groove 601, and the protective plate 602 is vertically and flexibly positioned within the receiving groove 601 via an elastic component. The elastic component includes a compression spring 603 and a telescopic rod 604. The bottom ends of both the compression spring 603 and the telescopic rod 604 are fixedly connected to the bottom end of the receiving groove 601, and the top ends of both are fixedly connected to the lower surface of the protective plate 602. The top end of the protective plate 602 has a push-button groove 605, and a rectangular block 606 is fixedly installed on the outer surface of the protective plate 602. A locking block 607 is fixedly installed on the upper surface of the receiving block 1 corresponding to the position of the rectangular block 606. When the protective plate 602 moves downward, the rectangular block 606 and the locking block 607 engage.

[0044] Through the above structure, the protective plate 602, supported by the compression spring 603 and the telescopic rod 604, remains raised at a certain height. When an external object may collide with the measuring equipment placed on the platform 7, the protective plate 602 can withstand the impact force first, providing a physical barrier to prevent the measuring equipment from being directly damaged by the collision, thus extending the service life of the measuring instrument and reducing maintenance costs. The combined design of the compression spring 603 and the telescopic rod 604 has excellent buffering and shock absorption performance. When the protective plate 602 is impacted, the compression spring 603 will undergo elastic deformation, and the telescopic rod 604 will also extend and retract accordingly. The two work together to disperse and absorb the impact force, reducing the impact force transmitted to the measuring equipment, further protecting the internal precision structure of the measuring equipment, and ensuring that the measuring equipment can still work normally after being subjected to accidental collisions. By opening a push-button groove 605 at the top of the protective plate 602, the measuring personnel can easily press the protective plate 602 by hand, causing it to move downward against the elastic force of the compression spring 603. When the rectangular block 606 moves down with the protective plate 602 and engages with the locking block 607, the protective plate 602 is fixed in a lower position. At this time, the measuring personnel can more easily operate, adjust, or pick up and put away the measuring equipment on the platform 7. After the operation is completed, the protective plate 602 is pressed again to disengage from the locking block 607. Under the action of the compression spring 603, the protective plate 602 resets and continues to play its protective role. The whole operation process is simple and convenient.

[0045] Preferably, the placement rack 8 fixedly installed on the placement platform 7 provides a stable and precise placement position for the infrared measuring instrument body 9. The placement rack 8 can limit the shaking and displacement of the infrared measuring instrument body 9, ensuring that the infrared measuring instrument body 9 maintains a relatively fixed posture during the measurement process, thereby improving the accuracy and stability of the measurement and reducing measurement errors caused by instrument shaking. The operator 11 set on the front of the placement rack 8 facilitates various operations of the infrared measuring instrument body 9 by the measuring personnel, such as turning the instrument on and off, setting measurement parameters, and viewing measurement data. The measuring personnel do not need to frequently touch the infrared measuring instrument body 9; most operations can be completed simply through the operator 11, improving the convenience and efficiency of operation, and also reducing the risk of damage to the instrument due to misoperation. The adjustment knob 10 set on the left side of the placement rack 8 can control the position operation of the infrared measuring instrument body 9. The measuring personnel can adjust the angle, height, or horizontal position of the infrared measuring instrument body 9 by rotating the adjustment knob 10 according to the actual measurement needs, so that the instrument can be accurately aligned with the measurement target, meeting the measurement requirements in different scenarios and enhancing the applicability and flexibility of the instrument.

[0046] In this embodiment, the self-locking hinge 2 can be a heavy-duty damping gimbal such as the SAF-LOCKH30 series, the infrared measuring instrument body 9 is a Topcon GPT-7500 high-precision intelligent total station, and the operator 11 is equipped with its original RC-5 wireless remote control handheld device; the power supply of the entire system is uniformly provided by the TP-4L lithium battery module integrated in the placement frame 8. This module provides DC power to the infrared measuring instrument body 9 and the operator 11 through a waterproof interface, while the electromagnetic braking unit of the self-locking hinge 2 is connected to the same power supply through the concealed wiring circuit inside the placement frame 8; in the linkage operation At this time, the surveyor first manually adjusts the self-locking hinge seat 2 to complete the rough leveling and locking. Then, the operator activates the automatic leveling compensation function of the infrared measuring instrument body 9 through the operator 11 to perform fine leveling. After the fine leveling is completed, a command is triggered on the interface of the operator 11. The command is transmitted to the control unit in the infrared measuring instrument body 9 via Bluetooth, which then drives the micro motor of the anti-settlement component 5 to perform the locking action of the gear 506 and the rack 507. At the same time, the operator 11 will simultaneously prompt that the protective plate 602 of the safety component 6 has entered the pressable locking state, thereby realizing the coordinated operation of the entire process from rough leveling, electronic fine leveling to mechanical locking.

[0047] The working principle of this embodiment is briefly described below:

[0048] When in use, the instrument is set up at the measurement station via the telescopic bracket 3, and the self-locking hinge seat 2 and the telescopic bracket 3 are operated for rough leveling.

[0049] Then, fine leveling is performed: rotate the three rotating rods 504 respectively. The rotating rods 504 drive the worm gear 503 to rotate. The worm gear 503 drives the worm wheel turning block 502 that meshes with it to rotate. The worm wheel turning block 502 drives the rotating screw 501 to rotate, so that the threaded receiving plate 509 moves up and down along the rotating screw 501, thereby driving the placement platform 7 and the infrared measuring instrument body 9 fixed on it to rise and fall, so as to achieve precise leveling of the instrument.

[0050] After leveling, to prevent the screw thread of the rotating screw 501 from slipping or undergoing plastic deformation under long-term load, causing the instrument to slowly sink, the anti-sinking component 5 needs to be activated for mechanical locking: Continue rotating the rotating rod 504, and the gear 506 at its end rotates synchronously. The gear 506 drives the rack 507, which meshes with it, to move. The abutment block 508 fixed on the rack 507 moves accordingly until its top forms a tight, rigid abutment with the bottom surface of the placement platform 7. At this time, the weight of the placement platform 7 is not only borne by the rotating screw 501, but also rigidly supported from below by the abutment block 508, forming an auxiliary load-bearing path independent of the screw thread, effectively eliminating the risk of slow sinking caused by screw thread failure. Simultaneously, the transmission between the worm gear 503 and the worm wheel turning block 502 has a self-locking characteristic, preventing reverse rotation and further ensuring the stability of the locked state.

[0051] After leveling and anti-settlement locking are completed, safety component 6 is activated to prevent accidental contact with adjusting components such as the rotating rod 504: Press the push-button groove 605 on the top of the protective plate 602 by hand, causing the protective plate 602 to slide downwards along the telescopic rod 604 against the elastic force of the compression spring 603. When the rectangular block 606 located on the outer ring of the protective plate 602 slides into the locking block 607, release the pressing force. The compression spring 603 rebounds, pushing the protective plate 602 slightly upwards. The locking structure of the locking block 607 limits the rectangular block 606, causing the rectangular block 606 to engage with the locking block 607, and the protective plate 602 remains in a depressed state. At this time, the protective plate 602 acts like a raised safety fence, completely surrounding the operating end of the rotating rod 504, effectively preventing damage to the leveling state caused by accidental contact with backpacks, clothing, or knees.

[0052] The infrared measuring instrument body 9 is controlled by the operator 11 and the adjustment knob 10 to perform normal measurement or layout operations. Since the instrument reference is mechanically locked by the anti-settlement component 5 and the adjustment parts are effectively protected by the safety component 6, the instrument can maintain extremely high stability throughout the operation.

[0053] After the operation is completed, press down the protective plate 602 again to disengage the rectangular block 606 from the locking block 607. The protective plate 602 will automatically reset under the action of the compression spring 603, exposing the adjustment mechanism. Then rotate the rotating rod 504 in the opposite direction to disengage the abutting block 508 from the abutting state with the placement platform 7, release the lock of the anti-settlement component 5, and the instrument can be safely stored.

[0054] Example 2

[0055] This embodiment describes the method of using an infrared measuring instrument for optical path alignment and calibration as described in Embodiment 1, including the following specific steps:

[0056] S1. Support the instrument at the measuring station using the telescopic bracket 3, and operate the self-locking hinge seat 2 to perform rough leveling.

[0057] S2. Then, rotate the rotating rods 504 of the three sets of anti-settlement components 5 respectively. Through the transmission of the worm gear 503 and the worm wheel turning block 502, drive the rotating screw 501 to lift the threaded receiving plate 509 and the placement platform 7, and complete the precise leveling of the infrared measuring instrument body 9.

[0058] S3. Continue to rotate each rotating rod 504 to drive the gear 506 at its end to mesh with the rack 507 to move horizontally, so that the abutting block 508 at the top of the rack 507 is firmly abutted against the bottom surface of the placement platform 7. The three sets of anti-sinking components 5 together form a rigid auxiliary support to prevent the threaded pair from undergoing plastic deformation due to long-term load, causing the instrument to slowly sink.

[0059] S4. Press down the protective plate 602 of the safety component 6, causing it to move down and be locked by the rectangular block 606 and the snap-fit ​​block 607. The protective plate 602 remains in a sunken state, forming a physical barrier around the operating ends of the three sets of rotating rods 504 to prevent accidental contact from damaging the leveling state.

[0060] S5. The infrared measuring instrument body 9 is controlled by the operator 11 and the adjustment knob 10 to complete the data acquisition or layout operation.

[0061] S6. After the operation is completed, release the lock of the protective plate 602 to reset it, and then rotate the rotating rod 504 in the opposite direction to release the abutment of the abutment block 508, so that the instrument can be safely stored.
