Description

Technical Field

[0001] This invention relates to the field of laser measurement instrument technology, specifically a laser instrument leveling adjustment device with attitude adaptive calibration. Background Technology

[0002] Laser leveling instruments are fundamental tools in modern engineering operations. Their core function is to emit lasers to form a horizontal reference surface, assisting in leveling and positioning operations. Their leveling accuracy, stability, and environmental adaptability directly determine the quality of the work. Especially in outdoor scenarios with no power supply and strong electromagnetic interference, the reliability requirements for the equipment are even higher.

[0003] Currently, laser leveling instruments on the market are mainly divided into two categories: manual leveling and automatic leveling, both of which have obvious shortcomings. Manual leveling instruments adjust the posture through three sets of retractable legs or ball joints and locking knobs. Operators need to repeatedly observe the bubble level and manually turn the knobs until the bubble is centered before locking. This solution is simple in structure and low in cost, but leveling depends entirely on the operator's experience and visual judgment. Multiple adjustments are required to achieve acceptable accuracy. The additional force during locking can easily cause the instrument posture to shift secondary. After a slight disturbance, it needs to be re-leveled and locked, which is extremely inefficient and cannot meet the needs of high-frequency station setups or vibrating environments.

[0004] Automatic leveling devices integrate MEMS tilt sensors or electronic bubble levels into the laser module mounting base to detect the tilt angle in real time. A microprocessor controls a servo motor to drive a lead screw or eccentric wheel mechanism for closed-loop compensation to level the object. This improves convenience and accuracy to some extent. However, the electronic control system is complex, has high manufacturing costs, and is difficult and costly to maintain. It also requires a high level of expertise from operators. The few purely mechanical leveling devices on the market mostly use simple gravity pendulums with spring reset, which can only achieve rough leveling in one direction. They lack effective power transmission and self-locking mechanisms, resulting in poor leveling accuracy and stability. Furthermore, the power distribution is unreasonable, and they cannot achieve closed-loop control of "tilt detection - power transmission - precise leveling - automatic locking," making them unsuitable for complex engineering scenarios.

[0005] The shortcomings of existing equipment have limited its widespread application, especially in harsh environments and high-precision scenarios. There is an urgent need for a device that combines simple structure, high reliability, precise automatic leveling, and stable self-locking. Summary of the Invention

[0006] The technical problem to be solved by the present invention is the problem of attitude adaptive calibration of laser measuring instruments, and provides a laser instrument leveling device for attitude adaptive calibration.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] The laser instrument horizontal adjustment equipment includes a test platform, on which a controller and a clamping table are provided;

[0009] The test bench is equipped with a guide unit, which includes a guide component. The guide component forms a guide offset by its own gravity. The guide component includes a guide element and an adjustment element. The clamping table is fixedly installed inside the guide element.

[0010] The guide unit is provided with a leveling unit, the leveling unit includes a leveling component, the leveling component adjusts the posture of the guide component by changing its position, the leveling component includes a leveling element and a control element, the control element and the adjustment element are fixedly connected, the leveling element and the control element are fixedly connected, the leveling element and the adjustment element are fixedly connected;

[0011] The controller, through signal reception, coordinates the actions of the control and leveling components to correct and adjust the attitude of the guide component. Existing laser instrument leveling equipment often struggles to adapt to complex engineering environments when faced with different tilt states, resulting in inaccurate leveling accuracy. This invention, through the cooperation of the guide and leveling units, automatically detects and levels the laser instrument's state under different operating conditions, thereby ensuring the accuracy of laser instrument leveling.

[0012] Furthermore, the leveling component includes a spiral spring, an input shaft, a sealing shell, a fixing plate, and a mounting rod. One end of the spiral spring extends out of the sealing shell and is fixedly connected to the output end of the telescopic motor. The other end of the spiral spring is fixedly connected to the input shaft. The input shaft is rotatably connected to the sealing shell and the mounting rod. The sealing shell is fixedly connected to the fixing plate. In the prior art, the leveling component suffers from poor elastic reset performance and problems such as input shaft rotation jamming. This invention provides elastic reset force by setting a spiral spring, ensuring smooth operation of the input shaft, sealing shell, and mounting rod, and avoiding operational jamming problems.

[0013] Furthermore, the control component includes an output shaft, a telescopic rod, a moving rod, a return spring, and a shielding cover. The output shaft is fixedly connected to one end of the telescopic rod, and the other end of the telescopic rod is fixedly connected to a mounting rod. A through hole is provided in the fixed plate, and the moving rod is slidably installed in the through hole of the fixed plate. The fixed plate and the shielding cover are connected by the return spring. The moving rod is fixedly connected to the shielding cover. A first disk is provided at the end of the moving rod near the output shaft, and a second disk is provided at the end of the output shaft near the moving rod. The first disk and the second disk have the same polarity. In the prior art, the movement adjustment of the control component is not flexible. This invention controls the movement of the moving rod by setting a structure where the disks with the same polarity repel each other, and the return spring enables the automatic reset of the shielding cover and the moving rod, ensuring the stable linkage between the control component and the leveling component.

[0014] Furthermore, the input shaft has a hollow structure, the inner surface of the input shaft is provided with an internal thread, and the outer surface of the output shaft is provided with an external thread that matches the internal thread of the input shaft.

[0015] Furthermore, the adjusting component includes an adjusting frame, a cross-groove frame, a slider, a top rod, a contact plate, and a bent rod. The mounting rod is fixedly connected to the adjusting frame, the adjusting frame is fixedly connected to the fixed end of the telescopic motor, the adjusting frame is fixedly connected to the test platform, and the adjusting frame is fixedly connected to the cross-groove frame. A guide groove is provided inside the cross-groove frame, the slider is slidably connected to the guide groove of the cross-groove frame, the slider is fixedly connected to the top rod, the top rod is fixedly connected to the contact plate, and the slider is connected to the shielding cover via the bent rod. In the prior art, the adjustment range of the adjusting component is limited, and it cannot guarantee the precise adjustment of the guide component's posture. This invention achieves multi-directional sliding of the slider through the guide groove of the cross-groove frame, and simultaneously connects the slider and the shielding cover via the bent rod, realizing the synchronous action of the adjusting component and the control component, thereby precisely adjusting the guide component's posture.

[0016] Furthermore, the guide component includes a gravity ball, a straight rod, and an inner frame. The gravity ball is fixedly connected to the straight rod, the contact plate abuts against the outer surface of the straight rod, the straight rod is fixedly connected to the inner frame, the inner frame is fixedly connected to the clamping stage, and the inner frame is connected to the test stage via a ball joint. Existing guide components have poor gravity guiding performance, and the connection between the inner frame and the test stage suffers from stiffness. This invention achieves precise gravity guiding by using a gravity ball to drive the straight rod, and the ball joint structure between the inner frame and the test stage ensures flexible multi-directional attitude displacement of the guide component.

[0017] Furthermore, a photoresistor is provided on the surface of the fixed plate at the end away from the input shaft. In existing technologies, the leveling process lacks a detection component, making it impossible to monitor the position of the shielding cover in real time, thus affecting leveling accuracy. This invention uses the change in the resistance value of the photoresistor to monitor whether the current position of the shielding cover has changed in real time, and feeds the detection signal back to the controller, achieving real-time monitoring of the leveling status.

[0018] Furthermore, the inner diameter of the shielding cover is the same as the outer diameter of the fixing plate.

[0019] Furthermore, the test bench is also equipped with a test unit, which includes a support frame, a cylinder and a test guide rail. The support frame is fixedly connected to the test bench, the fixed end of the cylinder is fixedly connected to the support frame, and the test guide rail is fixedly installed at the output end of the cylinder.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. After receiving a tilt trigger signal, the controller of this invention controls the output end of the telescopic motor to slowly extend. At this time, the stretched spiral spring begins to rewind, releasing the stored elastic potential energy, which drives the input shaft to rotate in the opposite direction and drives the output shaft to move to the left along the axial direction. This causes the second disk at the end of the output shaft to gradually approach the first disk of the moving rod. When the distance between the two disks is reduced to the effective range of the magnetic force, a strong repulsive force will be generated due to their identical polarity. This force pushes the first disk to move the moving rod and the cover to the left. This repulsive force is superimposed with the restoring force of the reset spring, which together drive the cover to gradually move away from the photoresistor. At the same time, the leftward movement of the cover will pull the slider along the guide groove of the cross slot frame to slide inward through the bent rod. The slider then pushes the straight rod in the opposite direction through the top rod and the contact plate, causing the straight rod to drive the gravity ball, the inner frame and the laser on the clamping table to deflect to a horizontal position, gradually correcting the tilt angle.

[0022] 2. In this invention, as the shielding cover moves to the left, the light intensity of the photoresistor gradually recovers, and its resistance value also returns to the preset horizontal reference value. When the controller detects that the resistance value of the photoresistor is exactly equal to the horizontal reference value, it indicates that the laser device has been precisely adjusted to a horizontal posture. At this time, the controller immediately sends a signal to stop the movement of the telescopic motor, and the output end of the telescopic motor is locked. At this time, the position of the output shaft is fixed, and a constant distance is maintained between the second disk and the first disk, continuously generating a stable repulsive force of the same pole. This repulsive force forms a transmission chain through the moving rod, shielding cover, bending rod, slider, top rod and contact plate, firmly holding the straight rod, realizing the automatic self-locking of the laser device's posture. Even if the equipment is subjected to slight vibration or disturbance, it can maintain a horizontal state.

[0023] 3. This invention places the pre-charged device on an engineering reference surface at any inclination. The laser instrument under test is fixedly mounted on the clamping platform. Under the action of gravity, the inner frame, clamping platform, laser instrument, and the straight rod and gravity ball fixedly connected below will deflect relative to the inclined test platform. The gravity ball always points vertically downward, causing the straight rod to swing in the opposite direction of the inclination. When the straight rod swings, its side will press against the contact plate in the corresponding direction. The contact plate pushes the slider to slide outward along the guide groove of the cross slot frame through the top rod. The bending rod pulls the shielding cover to move towards the fixed plate, compressing the return spring. At the same time, the shielding cover drives the moving rod fixed to it to slide to the right in the through hole of the fixed plate, so that the first disk at the end of the moving rod gradually approaches the second disk of the output shaft. During this process, the shielding cover will gradually cover the photoresistor on the surface of the fixed plate, causing the light intensity received by the photoresistor to decrease and the resistance value to change significantly. The controller collects the resistance signal of the photoresistor in real time. When the resistance change exceeds the preset threshold, it is determined that the device has tilted and the leveling program is immediately started. Attached Figure Description

[0033] 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.

[0034] Example: Figures 1-8 As shown, the present invention provides the following technical solution:

[0035] like Figures 1-3 As shown, the laser instrument horizontal adjustment equipment includes a test bench 1, on which a controller 11 and a clamping table 12 are installed;

[0036] The test bench 1 is equipped with a guide unit 2, which includes a guide component. The guide component forms a guide offset by its own gravity. The guide component includes a guide part and an adjustment part. The clamping table 12 is fixedly installed inside the guide part.

[0037] The guide unit 2 is provided with a leveling unit 3. The leveling unit 3 includes a leveling component. The leveling component adjusts the posture of the guide component by changing its position. The leveling component includes a leveling part and a control part. The control part and the adjustment part are fixedly connected. The leveling part and the control part are fixedly connected. The leveling part and the adjustment part are fixedly connected.

[0038] The controller 11 receives signals and coordinates the control and leveling components to operate synchronously, thereby correcting and adjusting the attitude of the guide component.

[0039] The laser instrument is guided and offset in different tilt states by the guide unit 2, then the laser instrument is leveled by the leveling unit 3, and finally the laser instrument is recalibrated by the test unit 4, thereby improving the accuracy and efficiency of automatic adjustment of the laser instrument.

[0040] like Figures 4-6 As shown, the leveling component includes a spiral spring 31, an input shaft 32, a sealing shell 33, a fixing plate 34, and a mounting rod 35. One end of the spiral spring 31 extends out of the sealing shell 33 and is fixedly connected to the output end of the telescopic motor. The other end of the spiral spring 31 is fixedly connected to the input shaft 32. The input shaft 32 is rotatably connected to the sealing shell 33 and the mounting rod 35. The sealing shell 33 is fixedly connected to the fixing plate 34.

[0041] After the device is powered on, the controller 11 first executes the initialization program, controls the output end of the telescopic motor to retract, pulls the spiral spring 31 to be stretched and deformed in the sealed shell 33, and stores elastic potential energy. At the same time, the input shaft 32 rotates as the spiral spring 31 is stretched.

[0042] like Figures 4-6 As shown, the control components include an output shaft 36, a telescopic rod 37, a moving rod 38, a return spring 39, and a cover 310. The output shaft 36 is fixedly connected to one end of the telescopic rod 37, and the other end of the telescopic rod 37 is fixedly connected to the mounting rod 35. A through hole is provided in the fixing plate 34, and the moving rod 38 is slidably installed in the through hole of the fixing plate 34. The fixing plate 34 and the cover 310 are connected by the return spring 39. The moving rod 38 is fixedly connected to the cover 310. A first disk is provided at the end of the moving rod 38 near the output shaft 36, and a second disk is provided at the end of the output shaft 36 near the moving rod 38. The first disk and the second disk have the same polarity.

[0043] like Figure 6As shown, the input shaft 32 is a hollow structure, and the inner surface of the input shaft 32 is provided with an internal thread. The outer surface of the output shaft 36 is provided with an external thread that matches the internal thread of the input shaft 32.

[0044] The input shaft 32 rotates, driving the output shaft 36 to move axially to the right, compressing the telescopic rod 37, thus widening the gap between the second disk at the end of the output shaft 36 and the first disk at the end of the moving rod 38. At this time, the entire leveling mechanism is in a standby state ready to be triggered. After receiving the tilt trigger signal, the controller 11 controls the output end of the telescopic motor to slowly extend. At this time, the stretched spiral spring 31 begins to wind up, releasing the stored elastic potential energy, driving the input shaft 32 to rotate in the opposite direction, driving the output shaft 36 to move axially to the left, compressing the telescopic rod 37, so that the second disk at the end of the output shaft 36 gradually approaches the first disk of the moving rod 38. When the gap between the two disks is reduced to the effective range of magnetic force, since they have the same polarity, a strong like-pole repulsive force will be generated, pushing the first disk to move the moving rod 38 and the cover 310 to the left. This repulsive force is superimposed with the restoring force of the reset spring 39, jointly driving the cover 310 to gradually move away from the photoresistor.

[0045] like Figures 4-8 As shown, the adjustment components include an adjustment frame 21, a cross-groove frame 22, a slider 23, a top rod 24, a contact plate 25, and a bent rod 26. The mounting rod 35 is fixedly connected to the adjustment frame 21. The adjustment frame 21 is fixedly connected to the fixed end of the telescopic motor. The adjustment frame 21 is fixedly connected to the test bench 1. The adjustment frame 21 is fixedly connected to the cross-groove frame 22. A guide groove is provided in the cross-groove frame 22. The slider 23 is slidably connected to the guide groove of the cross-groove frame 22. The slider 23 is fixedly connected to the top rod 24. The top rod 24 is fixedly connected to the contact plate 25. The slider 23 is connected to the cover 310 through the bent rod 26.

[0046] like Figure 3 , Figure 7 , Figure 8 As shown, the guide includes a gravity ball 27, a straight rod 28 and an inner frame 29. The gravity ball 27 is fixedly connected to the straight rod 28. The contact plate 25 abuts against the outer surface of the straight rod 28. The straight rod 28 is fixedly connected to the inner frame 29. The inner frame 29 is fixedly connected to the clamping table 12. The inner frame 29 is connected to the test table 1 by a ball hinge.

[0047] When the cover 310 moves to the left, it will pull the slider 23 along the guide groove of the cross slot frame 22 to slide inward via the bent rod 26. The slider 23 will then push the straight rod 28 in the opposite direction via the top rod 24 and the contact plate 25, so that the straight rod 28 will drive the gravity ball 27, the inner frame 29 and the laser on the clamping table 12 to deflect to the horizontal posture, gradually correcting the tilt angle.

[0048] As the cover 310 moves to the left, the light intensity of the photoresistor gradually recovers, and its resistance value returns to the preset horizontal reference value. When the controller 11 detects that the resistance value of the photoresistor is exactly equal to the horizontal reference value, it indicates that the laser device has been precisely adjusted to a horizontal position. At this time, the controller 11 immediately sends a signal to stop the movement of the telescopic motor, and the output end of the telescopic motor is locked. At this time, the position of the output shaft 36 is fixed, and the second disk and the first disk maintain a constant distance, continuously generating a stable repulsive force of the same pole. This repulsive force forms a transmission chain through the moving rod 38, the cover 310, the bent rod 26, the slider 23, the top rod 24 and the contact plate 25, firmly holding the straight rod 28, realizing the automatic self-locking of the laser device's posture. Even if the equipment is subjected to slight vibration or disturbance, it can maintain a horizontal state.

[0049] The pre-charged device is placed on an engineering reference surface at any inclination. The laser instrument to be tested is fixedly mounted on the clamping platform 12. Under the action of gravity, the inner frame 29, the clamping platform 12, the laser instrument, and the straight rod 28 and gravity ball 27 fixedly connected below will deflect relative to the inclined test platform 1. The gravity ball 27 always points vertically downward, causing the straight rod 28 to swing in the opposite direction of the inclination. When the straight rod 28 swings, its side will press against the contact plate 25 in the corresponding direction. The contact plate 25 pushes the slider 23 to slide outward along the guide groove of the cross slot frame 22 through the top rod 24, and through the bending rod 2 6. Pull the cover 310 towards the fixed plate 34 to compress the return spring 39. At the same time, the cover 310 drives the moving rod 38 fixed to it to slide to the right in the through hole of the fixed plate 34, so that the first disk at the end of the moving rod 38 gradually approaches the second disk of the output shaft 36. During this process, the cover 310 will gradually cover the photoresistor on the surface of the fixed plate 34, causing the light intensity received by the photoresistor to decrease and the resistance value to change significantly. The controller 11 collects the resistance value signal of the photoresistor in real time. When the resistance value change exceeds the preset threshold, it is determined that the device has tilted and the leveling program is immediately started.

[0050] like Figures 4-6 As shown, a photoresistor is provided on the surface of the fixed plate 34 away from the input shaft 32.

[0051] In order to monitor the position change of the cover 310 in real time and promptly feed the detection signal back to the controller 11, the real-time monitoring of the leveling status is realized, which makes it easier for the controller 11 to adjust the leveling action in a timely manner and further improve the leveling accuracy.

[0052] like Figure 4 As shown, the inner diameter of the cover 310 is the same as the outer diameter of the fixing plate 34.

[0053] To ensure the accuracy of the photoresistor detection signal and to guarantee the stability of the leveling process.

[0054] like Figure 1 As shown, the test bench 1 is also equipped with a test unit 4. The test unit 4 includes a support frame 41, a cylinder 42 and a test guide rail 43. The support frame 41 is fixedly connected to the test bench 1, the fixed end of the cylinder 42 is fixedly connected to the support frame 41, and the test guide rail 43 is fixedly installed at the output end of the cylinder 42.

[0055] After leveling and locking are completed, test unit 4 starts the calibration program. Cylinder 42 on support frame 41 pushes detection guide rail 43 to the preset detection position. The laser emits a horizontal laser beam that moves along detection guide rail 43. The photoelectric sensor on detection guide rail 43 collects the height deviation data of the laser beam, completes the automatic calibration of the laser leveling accuracy, and finally outputs the calibration result.

[0056] Working principle of the invention:

[0057] The pre-charged device is placed on an engineering reference surface at any inclination. The laser instrument to be tested is fixedly mounted on the clamping platform 12. Under the action of gravity, the inner frame 29, the clamping platform 12, the laser instrument, and the straight rod 28 and gravity ball 27 fixedly connected below will deflect relative to the inclined test platform 1. The gravity ball 27 always points vertically downward, causing the straight rod 28 to swing in the opposite direction of the inclination. When the straight rod 28 swings, its side will press against the contact plate 25 in the corresponding direction. The contact plate 25 pushes the slider 23 to slide outward along the guide groove of the cross slot frame 22 through the top rod 24, and through the bending rod 2 6. Pull the cover 310 towards the fixed plate 34 to compress the return spring 39. At the same time, the cover 310 drives the moving rod 38 fixed to it to slide to the right in the through hole of the fixed plate 34, so that the first disk at the end of the moving rod 38 gradually approaches the second disk of the output shaft 36. During this process, the cover 310 will gradually cover the photoresistor on the surface of the fixed plate 34, causing the light intensity received by the photoresistor to decrease and the resistance value to change significantly. The controller 11 collects the resistance value signal of the photoresistor in real time. When the resistance value change exceeds the preset threshold, it is determined that the device has tilted and the leveling program is immediately started.

[0058] After receiving the tilt trigger signal, the controller 11 controls the output end of the telescopic motor to slowly extend. At this time, the stretched spiral spring 31 begins to coil, releasing the stored elastic potential energy, which drives the input shaft 32 to rotate in the opposite direction and drives the output shaft 36 to move to the left along the axial direction. This causes the second disk at the end of the output shaft 36 to gradually approach the first disk of the moving rod 38. When the distance between the two disks is reduced to the effective range of the magnetic force, a strong repulsive force will be generated due to their identical polarity. This force pushes the first disk to move the moving rod 38 and the cover 310 to the left. This repulsive force is superimposed with the restoring force of the reset spring 39, which together drive the cover 310 to gradually move away from the photoresistor. At the same time, the leftward movement of the cover 310 will pull the slider 23 along the guide groove of the cross slot frame 22 inward through the bent rod 26. The slider 23 then pushes the straight rod 28 in the opposite direction through the top rod 24 and the contact plate 25, causing the straight rod 28 to drive the gravity ball 27, the inner frame 29 and the laser on the clamping table 12 to deflect to a horizontal position, gradually correcting the tilt angle.

[0059] As the cover 310 moves to the left, the light intensity of the photoresistor gradually recovers, and its resistance value returns to the preset horizontal reference value. When the controller 11 detects that the resistance value of the photoresistor is exactly equal to the horizontal reference value, it indicates that the laser device has been precisely adjusted to a horizontal position. At this time, the controller 11 immediately sends a signal to stop the movement of the telescopic motor, and the output end of the telescopic motor is locked. At this time, the position of the output shaft 36 is fixed, and the second disk and the first disk maintain a constant distance, continuously generating a stable repulsive force of the same pole. This repulsive force forms a transmission chain through the moving rod 38, the cover 310, the bent rod 26, the slider 23, the top rod 24 and the contact plate 25, firmly holding the straight rod 28, realizing the automatic self-locking of the laser device's posture. Even if the equipment is subjected to slight vibration or disturbance, it can maintain a horizontal state.
