[0002] A wireless laser displacement sensor is a device that can convert the displacement change of an object into an electrical signal and transmit data through wireless communication. Among them, the laser displacement sensor is a precision measuring instrument that uses laser technology to accurately measure parameters such as the displacement and distance of an object. During the use of the wireless laser displacement sensor, the basic function of the support is to provide a stable installation platform for the wireless displacement sensor, ensure that the sensor maintains the correct position and posture during operation, and prevent the sensor from shifting or being damaged due to factors such as vibration and impact, thereby ensuring the accuracy and reliability of the measurement.

[0003] In the application of traditional wireless laser displacement sensors, the installation and fixation of the sensor usually require precise adjustment of its measurement angle and level to ensure the accuracy of the measurement data. However, since the installation position and measurement angle of the sensor are often restricted by the on-site environment, and it is very difficult to perform precise fine-tuning after the installation through the support, in practical applications, problems such as low measurement accuracy and unstable installation are often faced. Especially in some complex or restricted working environments, the adjustment of the sensor is more difficult, which may lead to the inability to meet the measurement requirements of multiple positions and angles. Summary of the Invention

[0004] The purpose of the present invention is to propose an intelligent support adjusting device for a wireless laser displacement sensor to solve the problems that the installation position and measurement angle of the existing wireless laser displacement sensor are often restricted by the on-site environment, and it is very difficult to perform precise fine-tuning after the installation through the support. Therefore, in practical applications, problems such as low measurement accuracy and unstable installation are often faced.

[0005] To achieve the above purpose, the present invention adopts the following technology: An intelligent support adjusting device for a wireless laser displacement sensor, including an installation base plate, on which an adjusting plate capable of rotating on its surface is provided. An articulated plate is hinged to the adjusting plate through a connecting seat, and a support plate is detachably connected to the articulated plate through bolt fasteners. A driving component is arranged between the support plate and the adjusting plate, and the support plate can rotate in a direction perpendicular to the rotation plane of the adjusting plate through the driving component. A positioning mechanism capable of damping the installed sensor to ensure the stability of the sensor is arranged at the top of the support plate, and an installation component capable of improving the installation flexibility of the support is arranged on the installation base plate;

[0006] The support of the wireless laser displacement sensor can enable the wireless laser displacement sensor to achieve multi-dimensional automatic adjustment through the cooperation of the adjustment plate, the support plate and the driving component, so as to adapt to different installation environments and measurement requirements.

[0007] As a further description of the above technical solution: The driving component includes an electric cylinder. The cylinder body of the electric cylinder is connected to the adjustment plate through a first hinge seat, and the piston rod of the electric cylinder is connected to the support plate through a second hinge seat.

The output end of the control box is electrically connected to the input end of the electric cylinder.

[0009] As a further description of the above technical solution: The adjustment plate is rotatably connected to the top of the installation base plate through the cooperation of a connecting shaft and a bearing seat, and a limiting component for limiting and fixing the adjustment plate is arranged on the installation base plate.

[0010] As a further description of the above technical solution: The limiting component includes a limiting screw fixedly connected to the installation base plate.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] Refer to Figures 1 - 8 , an intelligent support adjusting device for a wireless laser displacement sensor provided in this embodiment includes a mounting base plate 1. An adjusting plate 2 capable of rotating on its surface is provided on the mounting base plate 1. A hinge plate 4 is hinged to the adjusting plate 2 through a connecting seat 3. And a support plate 5 is detachably connected to the hinge plate 4 through bolt fasteners. A driving assembly 6 is provided between the support plate 5 and the adjusting plate 2. And the support plate 5 can rotate along a direction perpendicular to the rotation plane of the adjusting plate 2 through the driving assembly 6. The driving assembly 6 includes an electric cylinder 61. The cylinder body of the electric cylinder 61 is connected to the adjusting plate 2 through a first hinge seat 62. And the piston rod of the electric cylinder 61 is connected to the support plate 5 through a second hinge seat 63. A control box 51 is provided on the support plate 5. And an inclination sensor 52 electrically connected to the control box 51 for detecting the inclination angle of the support plate 5 on the adjusting plate 2. The output end of the control box 51 is electrically connected to the input end of the electric cylinder 61.

[0030] In the present invention, when installing the wireless laser displacement sensor using the support, the wireless laser displacement sensor is installed on the support plate 5 through screw fasteners, and then the mounting base plate 1 is installed and fixed at the measurement site of the wireless laser displacement sensor through bolt fasteners, so that the laser emission end of the wireless laser displacement sensor is aligned with the object to be measured. When the laser beam emitted from the emission end of the wireless laser displacement sensor contacts the object to be measured, the reflected light forms an image on the photodetector through the lens. According to the principle of geometric optics, when the object undergoes displacement, the angle and position of the reflected light will change, resulting in a corresponding change in the imaging position on the detector. By measuring the change in the imaging position and using trigonometric relationships, the distance change between the object and the sensor can be calculated, thereby obtaining the displacement amount;

[0031] During actual installation, since the installation and fixation of the wireless laser displacement sensor require precise adjustment of its measurement angle and level to ensure the accuracy of measurement data, when the installation position and measurement angle of the wireless laser displacement sensor are restricted by the on-site environment, the angle of the sensor can be automatically adjusted by the telescopic movement of the electric cylinder 61. When the electric cylinder 61 is started, since the cylinder body of the electric cylinder 61 is hinged to the adjusting plate 2 through the first hinge seat 62, and the piston rod of the electric cylinder 61 is hinged to the support plate 5 through the second hinge seat 63, when the electric cylinder 61 expands and contracts, its two ends can freely rotate at the hinge points and will not be restricted in movement due to fixed connection. Thus, it can smoothly drive the support plate 5 to rotate relative to the adjusting plate 2, and further enable the wireless laser displacement sensor on the support to switch from one measurement point to another preset point for measurement, avoiding the trouble of manual adjustment and solving the problem that the installation position and measurement angle of the wireless laser displacement sensor are restricted by the on-site environment. The inclination sensor 52 provided on the support plate 5 can monitor the rotation angle of the support plate 5 and transmit the monitoring signal to the control box 51. The control box 51 adopts a common single-chip microcomputer control structure, and precisely controls the electric cylinder 61 through the control box 51, so that precise fine-tuning can be performed after the wireless laser displacement sensor is installed. Moreover, according to the inclination sensor 52, the angle between the support plate 5 and the adjusting plate 2 can be monitored. When the wireless displacement sensor is tilted, automatic leveling can be achieved according to the detection data of the inclination sensor 52 in cooperation with the electric cylinder 61;

[0032] Such as Figure 8As shown, during the specific use process, the operator will first pre-enter several points to be measured on the control chip in the control box 51 and set a timer, such as five minutes. After the laser displacement sensor on the support measures the first point, when the five-minute time limit is reached, the control center of the control box 51 reads the current angle of the laser displacement sensor through the inclination sensor 52. Then, the control center compares the current angle fed back by the inclination sensor 52 with the preset angle, controls the operation of the electric cylinder 61 to adjust the angle of the support. After the angle of the support is adjusted in place, it triggers the laser displacement sensor to test and record data. After five minutes, it continues to read the angle value to be tested this time from the already recorded data, and then controls the electric cylinder 61 to perform angle adjustment, so as to sequentially measure the pre-entered test points. This automatic adjustment can flexibly set multiple preset points at different positions and angles according to actual needs, ensuring a full-range and multi-angle detection of the object to be measured, obtaining more comprehensive and detailed data information, and helping to more accurately evaluate the state and characteristics of the object to be measured.

[0033] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, the adjusting plate 2 is rotatably connected to the top of the mounting base plate 1 through the cooperation of the connecting shaft 21 and the bearing seat 11, and a limiting component for limiting and fixing the adjusting plate 2 is arranged on the mounting base plate 1. The limiting component includes a limiting screw rod 12 fixedly connected to the mounting base plate 1. An adjusting notch 22 matching with the limiting screw rod 12 is formed on the adjusting plate 2. The adjusting notch 22 is arc-shaped and its center is located on the axis of the connecting shaft 21. A butterfly nut 13 abuting against the surface of the adjusting plate 2 is arranged on the limiting screw rod 12. An angle sensor 23 is arranged on the connecting shaft 21, and the angle sensor 23 is electrically connected to the control box 51.

[0034] After the wireless laser displacement sensor is installed through the support, it can not only achieve automatic angle adjustment through the cooperation of the driving component 6 and the inclination sensor 52, but also adjust its angle along the direction perpendicular to the rotation plane of the support plate 5 through the adjusting plate 2. The specific adjustment method is as follows: loosen the butterfly nut 13 on the limit screw 12 to reduce the pressure on the adjusting plate 2, and then rotate the adjusting plate 2. The adjusting plate 2 rotates on the mounting base plate 1 through the cooperation of the connecting shaft 21 and the bearing seat 11. Therefore, the adjusting plate 2 can rotate around the connecting shaft 21. During the rotation process, since the center of the arc-shaped adjusting notch 22 is located on the axis of the connecting shaft 21, it can be ensured that the limit screw 12 will not cause limit interference to the adjusting plate 2 during rotation. When the adjusting plate 2 rotates, the angle sensor 23 will transmit the rotation angle signal of the connecting shaft 21 to the control box 51, so that precise adjustment can be achieved through the angle sensor 23. Cooperating with the support plate 5 and the driving component 6, the displacement sensor can realize multi-dimensional automatic adjustment to adapt to different installation environments and measurement requirements. The switching of the laser displacement sensor between multiple positions is more flexible, significantly improving the measurement efficiency and accuracy, especially suitable for multi-point measurement requirements in complex working environments.

[0035] Specifically, as Figure 1 、 Figure 5 and Figure 6 shown, a positioning mechanism 7 for damping the installed sensor to ensure the stability of the sensor is provided at the top of the support plate 5. The positioning mechanism 7 includes a positioning plate 71 having at least two positioning holes 72. The positioning plate 71 is arranged above the support plate 5 through a damping component 73. The damping component 73 includes a connecting rod 731 passing through the support plate 5 and slidably connected thereto. A damping gasket 732 is provided at the top of the connecting rod 731 between the positioning plate 71 and the support plate 5. A limit nut 733 is provided on the connecting rod 731 by means of a thread, and a spring 734 is sleeved on the connecting rod 731 between the support plate 5 and the limit nut 733.

[0036] Among them, the lower half of the connecting rod 731 is a screw structure with a thread. When the positioning plate 71 is installed, the connecting rod 731 at the bottom of the positioning plate 71 passes through the connecting hole of the positioning plate 71 and abuts against the damping gasket 732, and then the limit nut 733 is screwed onto the threaded section of the connecting rod 731. The damping buffer of the positioning plate 71 is realized through the cooperation of the damping gasket 732 and the spring 734. When the laser displacement sensor is installed through the support, the laser displacement sensor is fixed on the positioning plate 71 by using screw fasteners in cooperation with the positioning holes 72 of the positioning plate 71. Therefore, its stability during use can be ensured through the damping component 73.

[0037] Specifically, as Figure 1 and Figure 7As shown, an installation component 8 capable of improving the installation flexibility of the support is provided on the installation base plate 1. The installation component 8 includes a sliding seat 81 disposed in the sliding groove 14 of the installation base plate 1. The sliding seat 81 can slide along the length direction of the sliding groove 14 through the cooperation of the connecting end 82 and the guiding groove 15. An installation hole 83 is formed in the middle position of the sliding seat 81.

[0038] Among them, when the installation base plate 1 is fixed at the use position of the laser displacement sensor by the bolt fastener, the bolt fastener passes through the installation hole 83 of the sliding seat 81, and the sliding seat 81 can slide in the sliding groove 14 of the installation base plate 1 through the cooperation of the connecting end 82 and the guiding groove 15. This movable sliding seat 81 enables the installer to quickly adjust the position of the installation bolt within a certain range without precisely aligning with the preset fixed hole positions. Especially when facing a complex or irregular installation surface, the bolt position can be quickly determined according to the actual situation, greatly improving the installation efficiency.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
