DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] Reference Figure 1-Figure 7 A handheld 3D laser scanner self-stabilizing device includes a support base 1 and a 3D laser scanner body 2. A handheld rod 3 is fixedly connected to the side wall of the support base 1. A battery 31 is installed on the upper end of the support base 1 to supply power to the 3D laser scanner body 2. This is prior art.
[0029] The stabilizing mechanism includes a groove 4 formed on the side wall of the support seat 1 away from the hand-held rod 3, the inner wall of the groove 4 is rotatably connected to a rotating seat 6 through a cross bar 5, the rotating seat 6 is provided with a circular groove 7 on the side wall away from the groove 4, the inner wall of the circular groove 7 is provided with an annular groove 8, and the inner wall of the annular groove 8 is slidably connected to a self-rotating circular plate 9 (such as Figure 3 As shown), the side wall of the three-dimensional laser scanner body 2 is fixedly connected to the side wall of the circular plate 9, and the side wall of the circular plate 9 is fixedly connected with a counterweight block 10 (as shown Figure 3 As shown), when the support base 1 is shaken left and right, the circular plate 9 will be automatically rotated to its original position under the action of the gravity of the counterweight block 10, so that the three-dimensional laser scanner body 2 is always in its original position.
[0030] Two slide grooves 11 are provided on the inner wall of the groove 4, and two sliders 12 are slidably connected to the inner walls of the two slide grooves 11 respectively. The side walls of the sliders 12 are rotatably connected to the side walls of the rotating seat 6 through a stabilizing rod 15. A first electric push rod 13 is fixedly connected to the inner wall of one of the slide grooves 11, and the movable end of the first electric push rod 13 is fixedly connected to the corresponding side wall of the slider 12. A second electric push rod 14 is fixedly connected to the inner wall of the other slide groove 11, and the movable end of the second electric push rod 14 is fixedly connected to the corresponding side wall of the slider 12.
[0031] A first trigger mechanism that triggers the extension and retraction of the first electric push rod 13 and the second electric push rod 14 is provided on the rotating seat 6. The first trigger mechanism includes a vertical cavity 16 opened in the support seat 1. The inner wall of the vertical cavity 16 is sealed and slidably connected with two first plates 17. The side walls of the two first plates 17 that are far away from each other are elastically connected to the inner wall of the vertical cavity 16 through multiple first springs 18. The side walls of the two first plates 17 that are close to each other and the inner wall of the vertical cavity 16 form a first balancing cavity 161. The first balancing cavity 161 is provided with a balancing liquid, which can be water. At the same time, a through hole is opened on the inner wall of the vertical cavity 16 close to the first spring 18 to balance the pressure change during the movement of the two first plates 17.
[0032] like Figure 3 As shown, the inner walls of the vertical cavity 16 are respectively fixedly connected with the first pressure sensor 19 and the second pressure sensor 20 , wherein one side wall of the first plate 17 is in contact with the side wall of the first pressure sensor 19 , and the other side wall of the first plate 17 is in contact with the side wall of the second pressure sensor 20 .
[0033] The first pressure sensor 19 is electrically connected to the first electric push rod 13 through the battery 31 and the external control mechanism, and the second pressure sensor 20 is electrically connected to the second electric push rod 14 through the battery 31 and the external control mechanism.
[0034] When the rotating seat 6 is kept in a vertical state in the vertical direction, the balancing liquid in the first balancing chamber 161 is kept horizontal, and the pressure of the balancing liquid on the two first plates 17 is consistent, so that the pressure signals on the first pressure sensor 19 and the second pressure sensor 20 are consistent. At this time, the first electric push rod 13 and the second electric push rod 14 are controlled by the external control mechanism to remain in place, so as to keep the rotating seat 6 in a vertical state in the vertical direction;
[0035] When the support seat 1 tilts to the left, the rotating seat 6 is driven to tilt to the left (such as Figure 3 As shown), at this time, the balancing liquid in the first balancing chamber 161 tilts to the left, and then the pressure on the first plate 17 on the left is greater than the pressure on the first plate 17 on the right. At this time, the pressure signal received by the first pressure sensor 19 is greater than the pressure signal received by the second pressure sensor 20, and then the first electric push rod 13 is controlled to contract and the second electric push rod 14 is controlled to extend through the external control mechanism, and then the two sliders 12 will drive the rotating seat 6 to rotate through the two stabilizing rods 15, so that the rotating seat 6 is kept in a vertical state in the vertical direction again. At this time, the balancing liquid in the first balancing chamber 161 remains horizontal, and then the external control mechanism controls the first electric push rod 13 and the second electric push rod 14 to remain in place, and the rotating seat 6 is kept in a vertical state in the vertical direction;
[0036] When the support seat 1 tilts to the right, the rotating seat 6 is driven to tilt to the right (such as Figure 3As shown), at this time, the balancing liquid in the first balancing chamber 161 tilts to the right, and then the pressure on the first plate 17 on the left is less than the pressure on the first plate 17 on the right. At this time, the pressure signal received by the first pressure sensor 19 is less than the pressure signal received by the second pressure sensor 20, and then the first electric push rod 13 is controlled to extend and the second electric push rod 14 is controlled to contract through the external control mechanism, and then the two sliders 12 will drive the rotating seat 6 to rotate through the two stabilizing rods 15, so that the rotating seat 6 is kept in a vertical state in the vertical direction again. At this time, the balancing liquid in the first balancing chamber 161 remains horizontal, and then the external control mechanism controls the first electric push rod 13 and the second electric push rod 14 to remain in place, and the rotating seat 6 is kept in a vertical state in the vertical direction;
[0037] So, in Figure 3 In the state shown, when the support seat 1 tilts left or right, it will automatically drive the rotating seat 6 to rotate to the vertical direction to maintain a vertical state, thereby ensuring the stability of the position of the three-dimensional laser scanner body 2 and avoiding the shaking of the three-dimensional laser scanner body 2 by the staff in the prior art, which causes the position of the three-dimensional laser scanner body 2 to change, making it impossible for the three-dimensional laser scanner body 2 to face the test point, thereby affecting its test results.
[0038] It should be noted that the external control mechanism can automatically adjust the extension and retraction of the first electric push rod 13 and the second electric push rod 14 according to the pressure signals received from the first pressure sensor 19 and the second pressure sensor 20, thereby achieving the stability of the position of the three-dimensional laser scanner body 2 by corresponding adjustments according to the left and right tilting state of the support base 1. The control method is the existing technology and will not be elaborated here.
[0039] A limiting mechanism for limiting the position of the cross bar 5 is provided on the support seat 1, and the limiting mechanism includes two limiting grooves 27 opened on the side wall of the support seat 1, and the limiting grooves 27 are circular in shape. The two ends of the cross bar 5 are respectively located in the two limiting grooves 27, and the side wall of the cross bar 5 located in the limiting groove 27 is fixedly connected with a friction sleeve 28. The inner wall of the limiting groove 27 is elastically connected with multiple friction plates 30 through multiple first magnetic springs 29, and the side wall of the friction plate 30 away from the first magnetic spring 29 is in contact with the side wall of the friction sleeve 28.
[0040] The first pressure sensor 19 is electrically connected to the first magnetic spring 29 through the battery 31 and the external control mechanism, and the second pressure sensor 20 is electrically connected to the first magnetic spring 29 through the battery 31 and the external control mechanism.
[0041] It should be noted that after the magnetic spring is energized, due to electromagnetic induction, the magnetic spring interacts with the current in the external magnetic field to generate pulling forces of different magnitudes to control the tensile deformation and movement state of the magnetic spring.
[0042] In the present invention, when the pressure signals on the first pressure sensor 19 and the second pressure sensor 20 are consistent, the external control machine cuts off the power to the first magnetic spring 29, and then the side walls of the multiple friction plates 30 are tightly fitted with the side walls of the friction sleeve 28, thereby limiting the rotation position of the cross bar 5. When the pressure signals on the first pressure sensor 19 and the second pressure sensor 20 are inconsistent, the external control machine energizes the first magnetic spring 29, so that the first magnetic spring 29 is energized and contracts, and then the multiple friction plates 30 are separated from the friction sleeve 28, thereby facilitating the subsequent adjustment of the position of the rotating seat 6.
[0043] The inner wall of the annular groove 8 is elastically connected with a friction ring 22 via a plurality of second magnetic springs 21 . The side wall of the friction ring 22 is in contact with the side wall of the circular plate 9 . A friction layer is provided on the side wall of the circular plate 9 close to the friction ring 22 .
[0044] A second trigger mechanism is provided in the circular plate 9, and the second trigger mechanism includes a transverse cavity 23 opened in the circular plate 9, and two second plates 24 are sealed and slidably connected to the inner wall of the transverse cavity 23, and the side walls of the two second plates 24 that are far away from each other are elastically connected to the inner wall of the transverse cavity 23 through multiple second springs 25. A second balancing cavity 231 is formed between the side walls of the two second plates 24 that are close to each other and the inner wall of the transverse cavity 23, and a balancing liquid is provided in the second balancing cavity 231. At the same time, a through hole is opened on the inner wall of the transverse cavity 23 close to the second spring 25 to balance the pressure changes of the two second plates 24 during the movement.
[0045] Two third pressure sensors 26 are fixedly connected to the inner walls of the transverse cavity 23, and the side walls of the two second plates 24 that are away from each other are respectively in contact with the side walls of the two third pressure sensors 26. The third pressure sensor 26 is electrically connected to the second magnetic spring 21 through the battery 31 and the external control mechanism.
[0046] like Figure 3-Figure 5 As shown, when the circular plate 9 is kept horizontal (as shown in Figure 5 As shown), at this time, the balancing liquid in the second balancing chamber 231 exerts the same pressure force on the two second plates 24, and the pressure signals received by the two third pressure sensors 26 are the same. At this time, the external control mechanism cuts off the power to the second magnetic spring 21, so that the friction ring 22 fits tightly with the side wall of the circular plate 9, thereby fixing the position of the three-dimensional laser scanner body 2;
[0047] When the rotating seat 6 tilts left and right, the circular plate 9 tilts left and right (such as Figure 5As shown), at this time, the squeezing force of the balancing liquid in the second balancing chamber 231 on the two second plates 24 is inconsistent, and the pressure signals received by the two third pressure sensors 26 are inconsistent. At this time, the external control mechanism energizes the second magnetic spring 21, and the second magnetic spring 21 is energized and contracts, so that the friction ring 22 is separated from the side wall of the circular plate 9, and then under the action of the gravity of the counterweight block 10, the circular plate 9 will be driven to automatically rotate to its original position, so that the three-dimensional laser scanner body 2 is always in its original position, so that the position of the three-dimensional laser scanner body 2 can be stabilized again.
[0048] In summary, at this time, combined with Figure 1 It is explained that when the staff holds the device, the device will shake back and forth and left and right (based on the moving direction of the hand-held rod 3) during this process, and then the position of the three-dimensional laser scanner body 2 can be automatically adjusted and stabilized, so that the three-dimensional laser scanner body 2 always maintains its initial position to avoid affecting its measurement results.
[0049] During use of the device, the worker holds the hand-held rod 3 and starts the 3D laser scanner body 2, and then can perform 3D data measurement in the underground space;
[0050] During the movement of the device, when the support seat 1 tilts to the left, the rotating seat 6 tilts to the left (such as Figure 3 As shown in the figure, at this time, the balancing liquid in the first balancing chamber 161 tilts to the left, and then the pressure on the first plate 17 on the left is greater than the pressure on the first plate 17 on the right. At this time, the pressure signal received by the first pressure sensor 19 is greater than the pressure signal received by the second pressure sensor 20. The external control machine energizes the first magnetic spring 29, so that the first magnetic spring 29 is energized and contracted, and then the multiple friction plates 30 are separated from the friction sleeve 28.
[0051] Then, the external control mechanism controls the first electric push rod 13 to contract and the second electric push rod 14 to extend, and then the two sliders 12 drive the rotating seat 6 to rotate through the two stabilizing rods 15, so that the rotating seat 6 is in a vertical state in the vertical direction again. At this time, the balancing liquid in the first balancing chamber 161 remains horizontal, and the pressure signals on the first pressure sensor 19 and the second pressure sensor 20 are consistent, and then the external control mechanism controls the first electric push rod 13 and the second electric push rod 14 to remain in place, and keep the rotating seat 6 in a vertical state in the vertical direction, and the external control mechanism cuts off the power to the first magnetic spring 29, and then the side walls of the multiple friction plates 30 are tightly fitted with the side walls of the friction sleeve 28, so as to limit the rotation position of the cross bar 5;
[0052] When the support seat 1 tilts to the right, the rotating seat 6 is driven to tilt to the right (such as Figure 3As shown in the figure, at this time, the balancing liquid in the first balancing chamber 161 tilts to the right, and then the pressure on the first plate 17 on the left side is less than the pressure on the first plate 17 on the right side. At this time, the pressure signal received by the first pressure sensor 19 is less than the pressure signal received by the second pressure sensor 20. The external control machine energizes the first magnetic spring 29, so that the first magnetic spring 29 is energized and contracted, and then the multiple friction plates 30 are separated from the friction sleeve 28.
[0053] Then, the external control mechanism controls the first electric push rod 13 to extend and the second electric push rod 14 to contract, and then the two sliders 12 will drive the rotating seat 6 to rotate through the two stabilizing rods 15, so that the rotating seat 6 is in a vertical state in the vertical direction again. At this time, the balancing fluid in the first balancing chamber 161 remains horizontal, and the pressure signals on the first pressure sensor 19 and the second pressure sensor 20 are consistent, and then the external control mechanism controls the first electric push rod 13 and the second electric push rod 14 to remain in place, keeping the rotating seat 6 in a vertical state in the vertical direction, and the external control machine cuts off the power to the first magnetic spring 29, so that the side walls of the multiple friction plates 30 are tightly fitted with the side walls of the friction sleeve 28, and the rotation position of the cross bar 5 is limited.
[0054] So, in Figure 3 In the state shown, when the support base 1 tilts left or right, it will automatically drive the rotating base 6 to rotate to the vertical direction to maintain a vertical state;
[0055] When the rotating seat 6 is kept in a vertical state in the vertical direction, the balancing liquid in the first balancing chamber 161 is kept horizontal, and the pressure of the balancing liquid on the two first plates 17 is consistent, so that the pressure signals on the first pressure sensor 19 and the second pressure sensor 20 are consistent, and the external control machine cuts off the power to the first magnetic spring 29, so that the side walls of the multiple friction plates 30 are tightly fitted with the side walls of the friction sleeve 28, and the rotation position of the cross bar 5 is limited, and the external control mechanism controls the first electric push rod 13 and the second electric push rod 14 to remain in place, so as to keep the support seat 1 in a vertical state in the vertical direction. At this time, the rotating seat 6 is in a vertical state in the vertical direction;
[0056] When the rotating seat 6 drives the circular plate 9 to tilt left and right (such as Figure 5 and Figure 6 As shown in the figure, at this time, the squeezing force of the balancing liquid in the second balancing chamber 231 on the two second plates 24 is inconsistent, and the pressure signals received by the two third pressure sensors 26 are inconsistent. At this time, the external control mechanism energizes the second magnetic spring 21, and the second magnetic spring 21 is energized and contracts, so that the friction ring 22 is separated from the side wall of the circular plate 9. Then, under the gravity of the counterweight 10, the circular plate 9 is automatically rotated to the original position, so that the three-dimensional laser scanner body 2 is always in the original position, so that the position of the three-dimensional laser scanner body 2 can be stabilized again;
[0057] Then the circular plate 9 is kept horizontal (such as Figure 5 and Figure 6 As shown), at this time, the balancing liquid in the second balancing chamber 231 exerts the same pressure force on the two second plates 24, and the pressure signals received by the two third pressure sensors 26 are the same. At this time, the external control mechanism cuts off the power to the second magnetic spring 21, so that the friction ring 22 fits tightly with the side wall of the circular plate 9, thereby fixing the position of the three-dimensional laser scanner body 2;
[0058] In this way, the position of the three-dimensional laser scanner body 2 is automatically adjusted and stabilized, so that the three-dimensional laser scanner body 2 always maintains the initial position to avoid affecting its measurement result.
[0059] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
