Abstract
Description
Technical Field
[0001] This invention relates to the field of wall inspection technology, and in particular to a high-precision laser ranging device for detecting the verticality of building walls. Background Technology
[0002] Perpendicularity measurement indicates whether the measured element on a part or building maintains the correct 90-degree angle with the reference element, which is usually referred to as the degree to which the two elements should be orthogonal. The elements of perpendicularity are generally lines and planes.
[0003] A search revealed Chinese patent CN112815881A, which discloses a verticality testing device for building construction. The device includes a main body, a rotating testing arm rotatably mounted on one end of its upper side, a rangefinder adjustment block connected to the end of the rotating arm away from its base, a fixed-head rangefinder housing on the lower side of the rotating arm, a movable rangefinder housing on the lower side of the rangefinder adjustment block, a movable-head rangefinder body inside the movable rangefinder housing, and a fixed-head rangefinder body inside the fixed-head rangefinder housing. This patented verticality testing device compares the distance measured by the fixed-head rangefinder body with the distance measured by the fixed-head rangefinder body. If the two distances are close, the wall is vertical to the ground; if the difference is large, it is not vertical. Simultaneously, it can calculate the included angle and the location of the tilt using the two sets of data. The results can be directly viewed and analyzed on a display, making it intuitive, accurate, and easy to use.
[0004] However, the above invention has the following shortcomings:
[0005] Existing wall laser measurement devices typically use a single laser sensor for measurement. Their working principle relies on emitting laser beams multiple times at a single point and receiving reflected signals to calculate distance or surface morphology. This single-point measurement method has obvious technical limitations: First, because the laser beam is easily affected by environmental factors (such as air disturbance, differences in surface reflectivity, or accidental obstruction) during propagation, the reliability of single-sensor measurement data is difficult to guarantee; second, when the measured wall surface has local unevenness or complex texture, the measurement results of a single sensor may not reflect the true characteristics of the overall surface, leading to the accumulation of measurement errors.

[0022] This invention provides an improved high-precision laser ranging device for detecting the verticality of building walls, which has the following improvements and advantages compared with the prior art:
[0023] Firstly, this invention utilizes a measuring mechanism. During measurement, a vertical plate is placed in front of the wall, and then a drive motor is activated. The drive motor drives a rotating shaft to rotate, which in turn rotates a transmission sleeve. Since the threads of each pair of corresponding transmission sleeves are opposite, the rotation of the transmission sleeves causes two transmission blocks to move closer together. This, in turn, causes the laser sensors on the mounting plates to move closer together. During this movement, the laser sensors intermittently emit lasers to measure the distance between the moving plate and the wall. By comparing the data from multiple measurements, if there are discrepancies, it can be determined that the wall is uneven. Simultaneously, when the two mounting plates move closer together, they compress the connecting rods, causing them to bend in the middle and move the second mounting block and the pressure sensor towards the wall. Since there are two pressure sensors, they are triggered when they come into contact with the wall. If the triggering times of the two pressure sensors are inconsistent, it also indicates that the wall is uneven, at which point an alarm will be activated, providing a warning. This achieves multiple measurement effects, thereby improving the accuracy of the measurement.
[0024] Secondly, this invention, through the setting of a protection mechanism and a transmission mechanism, ensures that when no measurement is being performed, the laser sensor is protected inside the protective cover. During measurement, the rotating shaft rotates, causing the transmission gear ring to rotate. The rotation of the transmission gear ring causes one of the transmission bevel teeth to rotate. The transmission bevel tooth two, through the mounting shaft one, drives the other transmission bevel tooth two to rotate, thereby driving the first transmission bevel tooth to rotate. The first transmission bevel tooth one is fixedly sleeved on the transmission screw, which is then driven to rotate. The transmission screw is connected to the two transmission blocks two through opposite threads, causing the two transmission blocks two to move away from each other inside the movable groove two. This, in turn, causes the two protective covers to move to both sides. At this time, the laser sensor also moves out from inside the protective cover. After the measurement is completed, the rotating shaft rotates in the opposite direction, indicating that the laser sensor has reset. The two protective covers also move closer to each other, so that the laser sensor returns to inside the protective cover after resetting and is protected. This achieves the effect of automatically releasing the laser sensor during use, thus protecting the laser sensor when no measurement is being performed.
[0025] Thirdly, this invention utilizes a leveling mechanism with two levels. Before measurement, the state of the levels can be observed to determine whether the base plate is level and the vertical plate is vertical. If the base plate is not level, the first adjusting screw on the higher side can be rotated. The first adjusting screw is threadedly connected to the first connecting sleeve, thus reducing the distance between them. At this time, the first flipping block will flip and move inside the base plate, thereby adjusting the base plate to one side until the level on the base plate is level. When the vertical plate is not vertical, the second adjusting screw can be rotated. The second adjusting screw is threadedly connected to the second connecting sleeve. Simultaneously, the adjusting plate is connected to the base via the second mounting shaft. At this time, the second flipping block will move inside the second flipping groove, thereby flipping the adjusting plate until the vertical plate becomes vertical. This achieves the effect of adjusting the laser sensor to the optimal position during measurement, avoiding the situation where the position of the laser sensor is offset, which could lead to measurement problems.

[0036] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.
[0037] This invention provides an improved high-precision laser ranging device for detecting the verticality of building walls. The technical solution of this invention is as follows:
[0038] like Figures 1 to 7 As shown, this embodiment of the invention provides a high-precision laser ranging device for detecting the verticality of building walls, including a base 1, an adjusting plate 2, and a vertical plate 3. The base 1 is a rectangular plate with casters 29 installed at the bottom. The adjusting plate 2 is movably mounted on the base 1. The vertical plate 3 is a rectangular plate that is set vertically upwards and is positioned above the adjusting plate 2. The vertical plate 3 has two movable slots 4, which are rectangular slots. The two movable slots 4 are distributed vertically and vertically. A partition 17 is fixedly installed between the two movable slots 4. A drive motor 5 is fixedly installed at the top of the vertical plate 3. A rotating shaft 6 is fixedly installed at the output end of the drive motor 5. The rotating shaft 6 is cylindrical and is located downwards inside the two movable slots 4. A measuring mechanism is provided on the vertical plate 3.
[0039] The measuring mechanism includes a transmission sleeve 7, a transmission block 1 8, a mounting plate 9, a laser sensor 10, a mounting block 11, a connecting rod 12, a mounting block 2 13, and a pressure sensor 14. The transmission sleeve 7 is a hollow cylindrical structure with threads. There are two sets of transmission sleeves 7, with two sleeves in each set. The two sets of transmission sleeves 7 are respectively located on the upper and lower sides inside the two movable slots 14 and are fixedly connected to the rotating shaft 6. The upper and lower threads of the two transmission sleeves 7 inside one movable slot 14 are opposite. The transmission block 18 is a rectangular block, and there are four transmission blocks 18. The four transmission blocks 18 are respectively movably installed on the upper and lower sides inside the two movable slots 14. The four transmission sleeves 7 pass through... The four transmission blocks 8 are threaded onto their upper and lower walls. Mounting plate 9 is a rectangular plate, fixedly mounted on the side walls of the four transmission blocks 8 at positions far apart from each other. Laser sensor 10 is fixedly mounted on the side wall between each pair of corresponding mounting plates 9, at a distance from each other. Mounting block 11 is a block structure, fixedly mounted on the side wall between each pair of corresponding mounting plates 9, at a close proximity. Connecting rod 12 is a rectangular rod, movably mounted on mounting block 11, and movably connected between two connecting rods 12. Mounting block 13 is a "C"-shaped block, movably mounted between two connecting rods 12. The pressure sensor 14 is fixedly mounted on mounting block 13. An alarm is installed on the vertical plate 3. The pressure sensor 14 is electrically connected to the alarm via a controller. During measurement, the vertical plate 3 is placed in front of the wall, and then the drive motor 5 is started. The drive motor 5 drives the rotating shaft 6 to rotate, which in turn drives the transmission sleeve 7 to rotate. Since the threads of each pair of corresponding transmission sleeves 7 are opposite, the rotation of the transmission sleeves 7 causes the two transmission blocks 8 to move closer to each other, thereby causing the laser sensor 10 on the mounting plate 9 to move closer to each other. During this movement, the laser sensor 10 intermittently emits laser light to measure the movement. The distance between the wall and the wall is compared by measuring the data multiple times. If there is a difference in the data from multiple measurements, it can be determined that the wall is uneven. At the same time, when the two mounting plates 9 are close to each other, they will squeeze the connecting rod 12, causing the two connecting rods 12 to bend from the middle, and drive the mounting block 13 and pressure sensor 14 to move towards the wall. Since there are two pressure sensors 14, when the pressure sensor 14 comes into contact with the wall, it will be triggered. When the triggering time of the two pressure sensors 14 is inconsistent, it can also indicate that the wall is uneven. At this time, the alarm will be activated and a warning will be issued.
[0040] A telescopic rod 15 is embedded in the vertical plate 3. The telescopic rod 15 is a telescopic cylindrical structure. A connecting block 16 is fixedly installed at one end of the telescopic rod 15. The connecting block 16 is a rectangular block. The other end of the connecting block 16 is fixedly connected to the second mounting block 13. The telescopic rod 15 can extend or retract when the second mounting block 13 moves, thereby limiting the movement of the second mounting block 13, so that the second mounting block 13 and the pressure sensor 14 can only move in the horizontal direction.
[0041] The vertical plate 3 is also equipped with a protective mechanism, which includes a movable slot 18, a transmission screw 19, a transmission block 20, and a protective cover 21. The movable slot 18 is a rectangular slot, which is opened on the vertical plate 3 corresponding to the position of the laser sensor 10. The transmission screw 19 is a cylindrical structure and is movably installed inside the movable slot 18. The transmission screw 19 has two opposite threads. The transmission block 20 is a rectangular block, and there are multiple transmission blocks 20. Multiple transmission blocks 20 are movably installed on both sides inside multiple movable slots 18. The transmission screw 19 passes through the side wall of the transmission block 20 through two opposite threads and is threadedly connected to it. The protective cover 21 is a hollow semi-rectangular structure and is set on the mounting plate 9. Two protective covers 21 can form a rectangular structure. The laser sensor 10 is located inside the protective cover 21. The two protective covers 21 are fixedly connected to two transmission blocks 20 respectively. The vertical plate 3 is equipped with a transmission mechanism.
[0042] The transmission mechanism includes a first transmission bevel gear 22, a first mounting shaft 23, a second transmission bevel gear 24, and a transmission gear ring 25. The first transmission bevel gear 22 is fixedly sleeved on the transmission screw 19. The first mounting shaft 23 is a cylindrical structure and is movably installed inside the vertical plate 3 corresponding to the position of the transmission screw 19. The first mounting shaft 23 and the transmission screw 19 are arranged perpendicularly. There are two second transmission bevel gears 24, which are respectively located at both ends of the first mounting shaft 23. One of the second transmission bevel gears 24 meshes with the first transmission bevel gear 22. The transmission gear ring 25 is an annular structure and is fixedly sleeved on the rotating shaft 6. The transmission gear ring 25 meshes with the other second transmission bevel gear 24. Through the setting of the protection mechanism and the transmission mechanism, when no measurement is being performed, the laser sensor 10 is protected inside the protective cover 21. During measurement, the rotating shaft 6 rotates, driving the transmission gear ring 25 to rotate. The rotation of the transmission gear ring 25 drives one of the transmission bevel gears 24. The rotating bevel gear 24 drives another bevel gear 24 to rotate via the mounting shaft 23, which in turn drives the first bevel gear 22 to rotate. The first bevel gear 22 is fixedly sleeved on the transmission screw 19, causing the transmission screw 19 to rotate. The transmission screw 19 is connected to the two transmission blocks 20 by opposite threads, causing the two transmission blocks 20 to move away from each other inside the movable groove 18. This causes the two protective covers 21 to move to both sides, and the laser sensor 10 will also move out of the protective cover 21. After the measurement is completed, the rotating shaft 6 rotates in the opposite direction, indicating that the laser sensor 10 has reset. The two protective covers 21 will also move closer to each other, so that the laser sensor 10 will return to the inside of the protective cover 21 after resetting and be protected. This achieves the effect of automatically releasing the laser sensor 10 during use and protecting the laser sensor 10 when not measuring.
[0043] A mounting shaft 27 is movably mounted on the base 1. An adjusting plate 2 is movably sleeved on the mounting shaft 27. The base 1 and the adjusting plate 2 are movably connected via the mounting shaft 27. A base plate 28 is fixedly mounted on the bottom of the vertical plate 3. The base plate 28 is a rectangular plate. A leveling mechanism is provided between the base plate 28 and the base 1. The leveling mechanism includes a level 26, a tilting groove 30, a tilting block 31, an adjusting screw 32, a slider 33, and a connecting screw sleeve 34. There are two levels 26, which are fixedly mounted on the base plate 28 and the base 1 respectively. The tilting groove 30... The groove is rectangular in structure. The flip groove 30 is opened on both sides of the base plate 28. The flip block 31 is a rectangular block and is movably installed inside the flip groove 30. The adjusting screw 32 is a threaded cylindrical structure and is movably installed on the flip block 31. The slider 33 is a rectangular block and is movably installed on the adjusting plate 2. The connecting screw sleeve 34 is a cylindrical structure and is fixedly installed on the top of the slider 33. The bottom of the adjusting screw 32 is located inside the connecting screw sleeve 34 and is threadedly connected to it.
[0044] A movable groove 35 is provided on the side wall of the base plate 28 corresponding to the position of the flipping block 31. The movable groove 35 is a rectangular groove. A limiting shaft 36 is installed on the side wall of the flipping block 31. The limiting shaft 36 is a cylindrical structure and is located inside the movable groove 35. The flipping block 31 is movably installed on the base plate 28 through the limiting shaft 36.
[0045] The leveling mechanism also includes a second tilting groove 37, a second tilting block 38, a second adjusting screw 39, and a second connecting screw sleeve 40. The second tilting groove 37 is a rectangular groove located on the adjusting plate 2. The second tilting block 38 is movably installed inside the second tilting groove 37. The second adjusting screw 39 is movably installed on the second tilting block 38. The second connecting screw sleeve 40 is movably installed at the bottom of the base 1. The bottom of the second adjusting screw 39 is threadedly installed inside the second connecting screw sleeve 40. Because the leveling mechanism includes two levels 26, the state of the levels 26 can be observed before measurement to determine whether the base plate 28 is level and whether the vertical plate 3 is vertical. If the base plate 28 is not level, the first adjusting screw 32 on the higher side can be rotated. The first adjusting screw 32 connects with the first connecting screw sleeve 30. The screws are connected to the base plate 28, which brings the distance between the adjusting screw 32 and the connecting sleeve 34 closer. At this time, the flipping block 31 will flip and move inside the base plate 28, thereby driving the base plate 28 to adjust the angle to one side until the level 26 on the base plate 28 is in a horizontal state. When the vertical plate 3 is not in a vertical state, the adjusting screw 39 can be rotated. The adjusting screw 39 is threadedly connected to the connecting sleeve 40. At the same time, the adjusting plate 2 is connected to the base 1 through the mounting shaft 27. At this time, the flipping block 38 will move inside the flipping groove 37, thereby driving the adjusting plate 2 to flip until the vertical plate 3 becomes vertical. This achieves the effect of adjusting the laser sensor 10 to the optimal position during measurement, avoiding the situation where the position of the laser sensor 10 is offset, which would cause problems with the measurement results.
[0046] Specific implementation steps
[0047] By setting up the measuring mechanism, during measurement, the vertical plate 3 is placed in front of the wall, and then the drive motor 5 is started. The drive motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 in turn drives the transmission sleeve 7 to rotate. Since the threads of each pair of corresponding transmission sleeves 7 are opposite, the rotation of the transmission sleeve 7 can drive the two transmission blocks 8 to move closer to each other, thereby driving the laser sensor 10 on the mounting plate 9 to move closer to each other. During the movement, the laser sensor 10 intermittently emits lasers to measure the distance between itself and the wall during the movement. By comparing the data from multiple measurements, if there are differences in the data from multiple measurements... This allows the system to determine if the wall is uneven. Simultaneously, when the two mounting plates 9 approach each other, they press against the connecting rod 12, causing it to bend in the middle and move the mounting block 13 and pressure sensor 14 towards the wall. Since there are two pressure sensors 14, they are triggered when they contact the wall. If the trigger times of the two pressure sensors 14 are inconsistent, it also indicates unevenness in the wall, at which point the alarm will activate, providing a multi-measurement effect and improving measurement accuracy.
