Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for measuring instruments, and in particular to a two-dimensional gimbal multi-angle leveling device. Background Technology

[0002] In the field of surveying and geographic information, the accuracy of topographic surveying and map making depends heavily on the accurate use of surveying instruments such as total stations and theodolites. To ensure that these instruments can perform at their best, the leveling and angle adjustment functions of the mounting and support devices are particularly important.

[0003] Currently available leveling devices have some limitations in practical applications. First, regarding leveling accuracy, many traditional leveling devices require manual adjustment, which is not only time-consuming but also makes it difficult to quickly and accurately adjust the measuring instrument to a level position. Due to the influence of human factors, it is difficult to guarantee that each adjustment will meet the requirements of high-precision measurement, which is a significant problem for highly demanding surveying work and affects the accuracy of measurement data.

[0004] Secondly, existing leveling devices lack sufficient flexibility in angle adjustment. Most devices only support angle adjustment in one or two directions, failing to meet the demands of complex and ever-changing measurement scenarios requiring multi-directional angle adjustment. For example, in irregular terrain conditions, fine adjustments to the instrument in multiple directions may be necessary, but traditional devices, limited by their adjustment range, struggle to cope with such complex environmental changes, thus restricting the efficiency and comprehensiveness of measurement work. Furthermore, with technological advancements, the demand for more intelligent and automated leveling and angle adjustment solutions is growing to improve work efficiency and reduce human error.

[0005] The above analysis shows that existing leveling devices on the market still have room for improvement in terms of accuracy, automation, and angle adjustment flexibility. This is crucial for improving the quality and efficiency of surveying and mapping work. Therefore, developing a two-dimensional gimbal multi-angle leveling device to overcome these shortcomings is of significant practical importance. Utility Model Content

[0006] To overcome the aforementioned drawbacks, this utility model provides a two-dimensional gimbal multi-angle leveling device.

[0007] The technical solution of this utility model is as follows: a two-dimensional gimbal multi-angle leveling device, including a mounting platform, a support frame, a fixed frame, a support block, a base, a sliding frame, a first screw, an tilt sensor, a controller, and a power component. The top of the base is provided with a sliding frame, and the first screw is vertically slidably connected inside the sliding frame. The top of the first screw is connected to a support block, and the fixed frame is horizontally rotatably connected to the support block. The support frame is rotatably connected to the fixed frame in the front-to-back direction, and the mounting platform is rotatably connected to the support frame in the left-to-right direction. The tilt sensor and the controller are sequentially installed on the top left side of the base, with the controller located in front and the tilt sensor located in the rear. The two are electrically connected to realize the interaction of data transmission and control commands.

[0008] Preferably, the power assembly includes a first motor, a second motor, and a third motor. The first motor is mounted on a support frame, and its output shaft is connected to the mounting platform. The second motor is mounted on a fixed frame, and its output shaft is connected to the support frame. The third motor is installed inside the support block, and its output shaft is connected to the fixed frame. The first motor, the second motor, and the third motor are all electrically connected to the controller and receive control commands from the controller to perform corresponding actions.

[0009] Preferably, the device also includes a fifth motor, a gear, and a rotating block. The fifth motor is mounted on the upper right side of the sliding frame, and a gear is connected to the output shaft of the fifth motor. A rotating block is rotatably connected to the top of the sliding frame, and a gear is also connected to the top of the rotating block. The two gears mesh with each other. A first screw passes through the gear on the sliding frame and is threadedly connected to the rotating block. The fifth motor is electrically connected to the controller.

[0010] Preferably, the device also includes a fourth motor, a guide frame, and rollers. The guide frame is connected to the top right side of the base, and the lower right side of the sliding frame is slidably connected to the inside of the guide frame via a slider. The fourth motor is mounted on the right side of the slider, and the rollers are connected to the output shaft of the fourth motor. The rollers are in close contact with the inside of the guide frame and form a friction fit. The fourth motor is electrically connected to the controller via wires.

[0011] Preferably, the device also includes a second screw and a suction cup. The second screw is symmetrically threaded through the center of the mounting platform, and a suction cup is installed at the bottom of each second screw.

[0012] Preferably, the suction cup is made of a material with high adhesion.

[0013] This invention has the following advantages: 1. The tilt sensor equipped with the device can monitor the tilt state of the base in real time and accurately, and quickly feed back the tilt angle signal to the controller. Based on these signals, the controller precisely drives the first motor and the second motor to work together, driving the mounting platform to make fine adjustments in the four tilt directions (front, back, left, and right), ensuring that the mounting platform can quickly reach a horizontal state, providing stable and accurate horizontal support for measuring instruments and other equipment, and greatly improving the accuracy of measurement data.

[0014] 2. Driven by the first, second, and third motors respectively, the mounting platform can not only be leveled in the front-back and left-right directions, but also rotate the fixed frame horizontally with the help of the third motor, thus achieving flexible adjustment of the equipment orientation on the mounting platform. This multi-angle adjustment function enables the device to meet the diverse needs of different measurement tasks and working scenarios for equipment angles, greatly enhancing the applicability of the device.

[0015] 3. The design of the fifth motor in conjunction with gears and rotating blocks makes adjusting the height of the mounting platform easy and convenient. Simply operate the controller to start the fifth motor, which will drive the first screw to move vertically through gear transmission, thereby raising or lowering the mounting platform. Meanwhile, the structure consisting of the fourth motor, guide frame, and rollers allows the operator to precisely control the forward and backward position of the sliding frame on the base via the controller, facilitating adjustments to the equipment's position in the forward and backward directions and improving the ease of operation in actual use.

Controller. Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] Example: Two-dimensional gimbal multi-angle leveling device, such as Figures 1-2 As shown, the system includes a mounting platform 1, a support frame 3, a fixed frame 5, a support block 7, a base 8, a sliding frame 11, a first screw 12, an inclination sensor 18, a controller 19, and a power assembly. The base 8 has a sliding frame 11 on top, and a first screw 12 is vertically slidably connected inside the sliding frame 11. The first screw 12 is connected to the top of the support block 7, and the fixed frame 5 is horizontally rotatably connected to the support block 7. The fixed frame 3 is rotatably connected to the fixed frame 5 in the front-to-back direction, and the mounting platform 1 is rotatably connected to the support frame 3 in the left-to-right direction. This system is used to support equipment that needs to be leveled, such as total stations, theodolites, and other measuring instruments. The inclination sensor 18 and the controller 19 are installed sequentially on the top left side of the base 8 by bolts. The controller 19 is located in front, and the inclination sensor 18 is located in the rear. The two are electrically connected to realize the interaction of data transmission and control commands. The inclination sensor 18 is used to monitor the tilt state of the base 8 in real time and outputs an electrical signal representing the tilt angle in different directions to the controller 19.

[0023] like Figure 2 As shown, the power assembly includes a first motor 2, a second motor 4, and a third motor 6. The first motor 2 is bolted to the support frame 3, and its output shaft is connected to the mounting platform 1 to drive the mounting platform 1 to rotate in the left and right directions. The second motor 4 is bolted to the fixed frame 5, and its output shaft is connected to the support frame 3 to drive the support frame 3 and the mounting platform 1 to rotate in the front and back directions. The third motor 6 is bolted to the support block 7, and its output shaft is connected to the fixed frame 5 to drive the fixed frame 5 to rotate in the horizontal direction, thereby adjusting the orientation of the mounting platform 1 and the equipment. The first motor 2, the second motor 4, and the third motor 6 are all electrically connected to the controller 19 and receive control commands from the controller 19 to perform corresponding actions.

[0024] In practical work scenarios in the field of surveying and geographic information, such as topographic surveying and map drawing, high-precision surveying instruments such as total stations and theodolites are required. The accurate measurement of these instruments depends on the horizontal state and precise orientation of the equipment. The working principle of this two-dimensional pan-tilt multi-angle leveling device is as follows: After the device is installed in the designated installation area, the tilt sensor 18 starts working in real time, continuously detecting the current tilt state of the base 8. When the device is placed on uneven ground, the base 8 will tilt in different directions. The tilt sensor 18 can accurately sense these tilt changes and output corresponding electrical signals. These electrical signals accurately reflect the tilt angle of the base 8 in the front-back, left-right, and other directions. After receiving the electrical signals output by the tilt sensor 18, the controller 19 analyzes and processes these signals according to the built-in algorithm to accurately determine the leveling requirements of the mounting platform 1. Based on the judgment result, the controller 19 sends control commands to the first motor 2 and the second motor 4. When the first motor 2 receives the start command, its output shaft starts to rotate, driving the mounting platform 1 to rotate and adjust in the left-right direction to correct the tilt angle of the mounting platform 1 in the left-right direction. Simultaneously, when the second motor 4 receives the start command, its output shaft rotates, driving the support frame 3 to rotate in the front-to-back direction. The mounting platform 1 also adjusts its angle in the front-to-back direction along with the rotation of the support frame 3. Through the coordinated work of the first motor 2 and the second motor 4, the mounting platform 1 can be precisely adjusted in four tilt directions (front, back, left, and right), driving the measuring instrument on the mounting platform 1 to adjust synchronously until the mounting platform 1 reaches a horizontal state. When it is necessary to adjust the orientation of the measuring instrument, the controller 19 sends a start command to the third motor 6. After the third motor 6 starts, its output shaft rotates, driving the fixed frame 5 to rotate in the horizontal direction, thereby driving the mounting platform 1 and the instrument to rotate synchronously, thus realizing the adjustment of the orientation of the measuring instrument and meeting the requirements of different measurement tasks for the instrument orientation.

[0025] like Figure 3 As shown, it also includes a fifth motor 13, a gear 14, and a rotating block 15. The fifth motor 13 is bolted to the upper right side of the sliding frame 11. The gear 14 is welded to the output shaft of the fifth motor 13. The rotating block 15 is rotatably connected to the top of the sliding frame 11. The top of the rotating block 15 is also welded with a gear 14. The two gears 14 mesh with each other. The first screw 12 passes through the gear 14 on the sliding frame 11 and is threadedly connected to the rotating block 15. This structural design can realize the vertical movement of the first screw 12 by driving the fifth motor 13, thereby adjusting the height of the mounting platform 1. The fifth motor 13 is electrically connected to the controller 19, which controls its start and stop to realize the adjustment of the height of the mounting platform 1.

[0026] When the height of the equipment on mounting platform 1 needs to be adjusted, the operator sends a start command to the fifth motor 13 via controller 19. After the fifth motor 13 starts, its output shaft rotates, driving the gear 14 connected to it to rotate. Since the two gears 14 mesh with each other, the gear 14 on the sliding frame 11 will rotate synchronously with the gear 14 on the output shaft of the fifth motor 13, thereby driving the rotating block 15 to rotate. This will drive the first screw 12 to move vertically. By controlling the forward and reverse rotation of the output shaft of the fifth motor 13, the first screw 12 can be moved up and down, thereby driving the support block 7, the fixed frame 5, the support frame 3 and the mounting platform 1 to move synchronously. The equipment on the mounting platform 1 will also rise and fall accordingly, completing the adjustment of the equipment height. After the adjustment is completed, the operator turns off the fifth motor 13 via controller 19, keeping the equipment at the required height position.

[0027] like Figure 3 As shown, it also includes a fourth motor 9, a guide frame 91, and a roller 10. The guide frame 91 is connected to the top right side of the base 8. The lower right side of the sliding frame 11 is slidably connected to the inside of the guide frame 91 through a slider. The fourth motor 9 is bolted to the right side of the slider. The roller 10 is connected to the output shaft of the fourth motor 9. The roller 10 is in close contact with the inside of the guide frame 91 and forms a friction fit. The fourth motor 9 is electrically connected to the controller 19 through a wire so as to receive control commands issued by the controller 19.

[0028] In actual operation, when it is necessary to adjust the front-to-back position of the equipment on the mounting platform 1, the operator sends a start command to the fourth motor 9 through the controller 19. After receiving the command, the output shaft of the fourth motor 9 starts to rotate, driving the roller 10 connected to it to rotate synchronously. Due to the friction between the roller 10 and the inner surface of the guide frame 91, the rotation of the roller 10 generates a force along the direction of the guide frame 91. This force pushes the fourth motor 9 and the slider connected to it to move within the guide frame 91. Since the slider is fixedly connected to the sliding frame 11, the movement of the slider further drives the sliding frame 11 to adjust its position in the front-to-back direction along the top surface of the base 8. By controlling the forward or reverse rotation of the output shaft of the fourth motor 9, the movement of the sliding frame 11 can be precisely controlled to move forward or backward, thereby achieving precise adjustment of the front-to-back position of the equipment on the mounting platform 1. When the equipment is adjusted to the required position, the operator sends a stop command to the fourth motor 9 through the controller 19 again, turning off the fourth motor 9 and keeping the sliding frame 11 in its current position.

[0029] like Figure 1 and Figure 4 As shown, it also includes a second screw 16 and a suction cup 17. The second screw 16 is symmetrically threaded through the middle of the mounting platform 1. The bottom of the second screw 16 is equipped with a suction cup 17. The suction cup 17 is made of a material with high adsorption force, which can firmly adsorb the base 8 onto the support surface such as the table or the ground when the device is working.

[0030] Before using the device, if it needs to be securely fixed to a support surface such as the ground or a table, the operator needs to use a suitable tool, such as a wrench, to tighten the second screw 16 in the middle of the mounting platform 1. Since the second screw 16 is connected to the mounting platform 1 by threads, tightening the second screw 16 will cause it to move downwards along the thread direction, thereby causing the suction cup 17 installed at the bottom of the second screw 16 to gradually extend downwards. When the suction cup 17 is in full contact with the support surface, the air inside the suction cup 17 is squeezed out, forming a negative pressure environment, thereby firmly adsorbing the base 8 onto the support surface, achieving stable fixation of the device, and ensuring that the device will not be displaced due to external interference during operation. When the device is finished or needs to be changed, the operator first separates the base 8 from the support surface, and then uses a tool to rotate the second screw 16 in the opposite direction. As the second screw 16 rotates in the opposite direction, it moves upwards along the thread direction, causing the suction cup 17 to retract upwards into the base 8, facilitating the storage and transportation of the device.
