Abstract
Description
Technical Field
[0001] This invention relates to the field of measuring devices, and in particular to an automatic measuring device and method for the foundation and opening of iron towers. Background Technology
[0002] Transmission lines, especially high-voltage lines, typically require foundation types selected according to local conditions. In areas with significant elevation differences and complex surrounding environments, foundations should ideally employ unequal height designs to minimize or eliminate the need for foundation excavation, thus preventing vegetation damage, reducing soil erosion, and minimizing earthwork excavation and concrete pouring. Therefore, to ensure construction quality, precise measurements of the foundation's base opening and diagonal are frequently necessary during construction. Foundation construction must comply with the requirements of the "110-750kV Overhead Transmission Line Construction and Acceptance Specifications." Strict control of the foundation's base opening and top elevation difference is crucial during transmission tower installation, especially in mountainous and hilly areas with significant elevation differences. The base opening and top elevation difference severely impact the operational safety of the transmission tower. Furthermore, manual measurement is complex and involves substantial calculations.
[0003] Foundation construction is one of the crucial parameters for the installation and safe operation of transmission towers. The quality of the foundation construction directly impacts the safe and stable operation of the transmission circuit. Deviations between the foundation data and the design verification data can lead to instability of the transmission tower, posing a risk of toppling during severe storms or prolonged operation. This increases the potential for unstable operation of the transmission line and raises maintenance costs.
[0004] Currently, manual measurement methods still largely rely on traditional tools such as steel tape measures and theodolites. These tools are complex due to the large number of measurement parameters and the intricate calculation methods, and are difficult to use. However, with the development of electronic equipment, the digital transformation of measuring devices, and the powerful computing capabilities of computers, we can simplify or even replace manual measurement.
[0005] Meanwhile, considering that the testing environment is mostly mountainous and hilly areas with uneven terrain, and the measuring device needs to be used for measurement in a horizontal plane, it is necessary to manually level the measuring device. However, manual leveling is complicated, time-consuming and labor-intensive, which seriously affects the measurement efficiency. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art, which requires manual leveling of the measuring device, which is complicated, time-consuming and labor-intensive, and seriously affects the measurement efficiency. This invention provides an automatic measuring device and method for the foundation and opening of iron towers.
[0007] The objective of this invention can be achieved through the following technical solutions:
[0008] An automatic measuring device for tower foundation and opening includes a support platform for supporting the device. The device also includes a measuring component and a leveling component for adjusting the initial horizontal position of the measuring component. The measuring component is fixed above the leveling component. The leveling component includes two vertically arranged leveling mechanisms, which are used to make the initial horizontal position of the measuring component.
[0009] Preferably, the leveling structure includes a servo motor, a worm gear, a worm gear fixing plate, a turbine gear, and a turbine gear fixing plate. The servo motor drives and connects to the worm gear. The worm gear fixing plate has a first protrusion, and the first protrusion has a first groove that matches the shape of the turbine gear. The worm gear is rotatably fixed at the bottom end of the first groove. The lower end of the turbine gear fixing plate has an arc-shaped structure corresponding to the curvature of the turbine gear. The lower end of the turbine gear fixing plate has a second groove that matches the first protrusion. The turbine gear is fixed at the upper end of the second groove. The second groove connects to the first protrusion. The worm gear meshes with the turbine gear. The motor drives the worm gear to rotate, and the worm gear drives the turbine gear to rotate circumferentially, which in turn drives the turbine gear fixing plate to rotate. Through a pair of vertically arranged leveling structures, the arbitrary angle adjustment of the measuring component with the horizontal plane can be achieved.
[0010] Preferably, the leveling assembly includes a first leveling mechanism and a second leveling structure. The worm gear fixing plate of the first leveling structure is fixed above the support platform, the worm gear fixing plate of the second leveling mechanism is fixed to the turbine fixing plate of the first leveling structure, and the measuring assembly is fixed to the turbine fixing plate of the second leveling mechanism.
[0011] Preferably, the measuring device further includes a control module and an inclination sensor connected to each other. The control module is connected to a servo motor and is used to control the servo motor to drive the worm gear to rotate, and further control the action of the leveling component. The inclination sensor is fixed in the main plane of the measuring component and is used to detect the angle between the main plane of the measuring component and the horizontal plane, and transmit the angle data to the control module.
[0012] Preferably, the measuring component includes a rotating component and a measuring component. The rotating component is fixed above the leveling component, and the measuring component is fixed above the rotating component. The rotating component is used to drive the measuring component to rotate in the horizontal plane.
[0013] Preferably, the rotating component includes a rotating motor, a rotating bracket, and a rotating connector. The lower end of the rotating bracket is connected to a leveling assembly, the rotating motor is fixed above the rotating bracket, and the rotating motor drives the measuring component through the connector.
[0014] Preferably, the rotating frame includes a first side plate, a second side plate, and a motor fixing plate. The first side plate and the second side plate are symmetrically fixed on both sides of the turbine fixing plate of the second leveling structure. The motor fixing plate is vertically fixed to the upper ends of the first side plate and the second side plate, and the rotating motor is vertically fixed on the motor fixing plate.
[0015] Preferably, the measuring component includes a rotating disk, a laser rangefinder, and a rangefinder adjustment platform for adjusting the vertical measurement angle of the laser rangefinder. The rotating motor drives and connects to the rotating disk, the rangefinder adjustment platform is fixed on the rotating disk, the laser rangefinder is fixed on the rangefinder adjustment platform, and the rotating motor, in conjunction with the rotating disk, is used to adjust the horizontal measurement angle of the laser rangefinder.
[0016] Preferably, the rotating disk includes a rotating base plate, a first support plate, and a second support plate. The rotating motor drives and connects to the rotating base plate. The first support plate and the second support plate are fixed at both ends of the rotating base plate to support and fix the rangefinder adjustment platform.
[0017] The rangefinder adjustment platform includes an adjustment motor and a laser rangefinder mounting plate. The adjustment motor is vertically fixed to one side of the second support plate. One end of the laser rangefinder mounting plate is rotatably connected to the first support plate, and the other end is driven to connect to the adjustment motor. The laser rangefinder is fixed on the laser rangefinder mounting plate. The adjustment motor is used to drive the laser rangefinder mounting plate to rotate, thereby further adjusting the angle of the laser rangefinder in the vertical plane.
[0018] This solution also provides an automatic measurement method for tower foundation and foundation opening, including the following steps:
[0019] After the concrete pouring of the tower foundation is completed, the equipment is placed at point O of the foundation center pile; reflective strips are attached to the center of the four tower foundations.
[0020] Place the device at point O, the center of the central pile, activate the tilt sensor to read the angle between the device and the horizontal plane, and transmit the measurement data to the host computer.
[0021] The host computer controls the leveling component to move according to the measurement data. The servo motor drives the worm to rotate, and the rotation of the worm drives the meshing turbine to rotate, so that the worm fixing plate and the turbine fixing plate move relative to each other along the first groove until the tilt sensor on the rotating base plate detects that the measuring component is in a horizontal state, and the host computer controls the servo motor to stop.
[0022] After the device completes the leveling process, the measurement begins. The laser sensor is activated, and the rotating motor is controlled to drive the rotating base plate to rotate. This allows the laser rangefinder to measure the reflective strips arranged around the device. When the laser hits the reflective strip, the laser rangefinder receives a strong signal feedback as a stop signal.
[0023] When the device receives a stop signal and stops, it reads the measured distance of the laser rangefinder and the relative rotation angle of the rotating motor and the adjusting motor, and calculates the coordinates in the horizontal equipment coordinate system based on this data;
[0024] The foundation and span of the iron tower are calculated based on the obtained coordinates. The calculation results are output to the display device and the system waits for the next measurement instruction.
[0025] Compared with the prior art, the present invention has the following advantages:
[0026] (1) This solution sets a leveling component below the measuring component. The two leveling mechanisms arranged perpendicularly to each other can adjust the measuring device in two mutually perpendicular directions, thereby enabling the measuring component to be adjusted at any angle in the horizontal plane. The leveling component has a simple structure, can quickly adjust the measuring component, and is more accurate and efficient than manual adjustment.
[0027] (2) This solution uses a worm gear structure in conjunction with an arc-shaped connection structure to make the connection structure reliable. At the same time, driven by the servo motor and the worm, the worm drives the worm mounting plate to rotate, thereby realizing the adjustment of the measurement group's position in the horizontal direction. The leveling structure is simple and reliable.
[0028] (3) This solution uses a tilt sensor on the measuring component. The tilt sensor transmits the angle between the main plane of the measuring component (i.e., the plane where the laser rangefinder mounting plate is located) and the horizontal plane to the control module. The control module adjusts the first and second leveling structures according to the angle, reducing the measurement result of the tilt sensor and ensuring that the initial position of the laser rangefinder mounting plate is horizontal. This facilitates measurement by the measuring component and ensures the accuracy of the measurement results. Automated leveling of the measuring component is achieved, further improving leveling efficiency while ensuring leveling accuracy. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0042] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0044] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed during use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0045] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0046] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0047] Example 1
[0048] like Figure 1 and Figure 11 As shown, this embodiment provides an automatic measuring device for tower foundation and opening, including a support platform 1 for supporting the device. The device also includes a measuring component and a leveling component 2 for adjusting the initial position of the measuring component to be horizontal. The measuring component is fixed above the leveling component 2. The leveling component 2 includes two vertically arranged leveling mechanisms, which make the initial position of the measuring component horizontal.
[0049] By setting a leveling component below the measuring component, two mutually perpendicular leveling mechanisms can be used to adjust the measuring device in two mutually perpendicular directions, thereby enabling the measuring component to be adjusted at any angle in the horizontal plane. The leveling component has a simple structure, allows for rapid adjustment of the measuring component, and provides more accurate and efficient results compared to manual adjustment.
[0050] In this embodiment, as Figure 10 As shown, a tripod is provided below the support platform 1, and the tripod is connected to the lower end of the support platform 1 by a pin. A square groove is milled in the center of the upper part of the support platform 1, and a threaded hole is provided at the bottom of the square groove for connecting the stable leveling component 2.
[0051] As a preferred implementation method, such as Figure 1-3As shown, the leveling structure includes a servo motor 3, a worm gear 4, a worm gear fixing plate 5, a turbine 6, and a turbine fixing plate 7. The servo motor 3 drives and connects to the worm gear 4. The worm gear fixing plate 5 has a first protrusion and a first groove that matches the shape of the turbine 6. The worm gear 4 is rotatably fixed at the bottom end of the first groove. The lower end of the turbine fixing plate 7 is an arc-shaped structure corresponding to the curvature of the turbine 6. The lower end of the turbine fixing plate 7 has a second groove that matches the first protrusion. The turbine 6 is fixed at the upper end of the second groove. The second groove connects to the first protrusion. The worm gear 4 meshes with the turbine 6. The motor drives the worm gear 4 to rotate, which in turn drives the turbine 6 to rotate circumferentially, further driving the turbine fixing plate 7 to rotate. Through a pair of vertically arranged leveling structures, the arbitrary angle adjustment of the measuring component with the horizontal plane can be achieved.
[0052] Furthermore, such as Figure 4-9 As shown, the leveling assembly 2 includes a first leveling mechanism and a second leveling structure. The worm gear fixing plate 5 of the first leveling structure is fixed above the support platform 1, the worm gear fixing plate 5 of the second leveling mechanism is fixed on the turbine fixing plate 7 of the first leveling structure, and the measuring assembly is fixed on the turbine fixing plate 7 of the second leveling mechanism.
[0053] The worm gear structure combined with the arc-shaped connection structure makes the connection structure reliable. At the same time, driven by the servo motor and the worm, the worm drives the worm gear fixing plate to rotate, thereby realizing the adjustment of the position of the measuring group in the horizontal range. The leveling structure is simple and reliable.
[0054] In this embodiment, the leveling component 2 achieves overall planar leveling of the measurement component by superimposing two single-axis leveling structures. The single-axis leveling structure includes a turbine fixing plate, a worm fixing plate, a turbine, a worm, an arc-shaped dovetail joint, and a servo motor. The rotation of the servo motor drives the worm to rotate the turbine, and the turbine fixing plate and the worm fixing plate achieve relative arc motion under the constraint of the dovetail groove and the transmission of the worm gear.
[0055] Furthermore, the turbine employs a larger radius of curvature, resulting in a smoother contact section between the worm gear and the worm, and more precise angle adjustment. The required turbine is cut and connected to the turbine mounting plate via threads. A dovetail-like arc groove is used to position and stabilize the transmission of the worm gear structure. Simultaneously, the worm mounting plate is milled with an arc-shaped surface corresponding to the turbine mounting plate to create the worm's rotation space. The worm is positioned and fixed to the worm mounting plate using an arc-shaped dovetail tenon.
[0056] Specifically, the measuring device also includes a control module and a tilt sensor connected to each other. The control module is connected to the servo motor 3 and is used to control the servo motor 3 to drive the worm gear 4 to rotate, further controlling the action of the leveling component 2. The tilt sensor is fixed in the main plane of the measuring component and is used to detect the angle between the main plane of the measuring component and the horizontal plane, and transmit the angle data to the control module. In this embodiment, the tilt sensor is fixed above the rotating base plate 16.
[0057] By installing a tilt sensor on the measuring component, the tilt sensor transmits the angle between the main plane of the measuring component (i.e., the plane where the rotating base plate 16 is located) and the horizontal plane to the control module. The control module adjusts the first and second leveling structures accordingly based on the angle, reducing the measurement result of the tilt sensor and ensuring that the rotating base plate is initially in a horizontal position. This facilitates measurement by the measuring component and ensures the accuracy of the measurement results. Automated leveling of the measuring component is achieved, further improving leveling efficiency while maintaining leveling accuracy.
[0058] In a preferred embodiment, the measuring component includes a rotating member 8 and a measuring member 9. The rotating member 8 is fixed above the leveling component 2, and the measuring member 9 is fixed above the rotating member 8. The rotating member 8 is used to drive the measuring member 9 to rotate in the horizontal plane.
[0059] Specifically, the rotating component 8 includes a rotating motor 10, a rotating bracket, and a rotating connector 11. The lower end of the rotating bracket is connected to the leveling assembly 2. The rotating motor 10 is fixed above the rotating bracket and drives the measuring component 9 through the connector. The rotating frame includes a first side plate 12, a second side plate 13, and a motor fixing plate 14. The first side plate 12 and the second side plate 13 are symmetrically fixed on both sides of the turbine fixing plate 7 of the second leveling structure. The motor fixing plate 14 is vertically fixed to the upper ends of the first side plate 12 and the second side plate 13. The rotating motor 10 is vertically fixed on the motor fixing plate 14.
[0060] During operation, the leveling assembly drives the motor fixing plate 14 via the first side plate 12 and the second side plate 13, which in turn drives the rotating base plate 16 via the connected rotating motor 10, thus achieving leveling of the rotating base plate 16. Furthermore, during laser rangefinder measurement, the rotating base plate 16 can be rotated via the rotating motor 10, thereby adjusting the adjustment angle of the laser rangefinder 15, improving the device's ability to measure a full circumference and enhancing the ease of measurement.
[0061] Specifically, the measuring component 9 includes a rotating disk, a laser rangefinder 15, and a rangefinder adjustment platform for adjusting the vertical measurement angle of the laser rangefinder 15. A rotating motor 10 drives and connects to the rotating disk. The rangefinder adjustment platform is fixed on the rotating disk. The laser rangefinder 15 is fixed on the rangefinder adjustment platform. The rotating motor 10, in conjunction with the rotating disk, is used to adjust the horizontal measurement angle of the laser rangefinder 15.
[0062] Furthermore, the rotating disk includes a rotating base plate 16, a first support plate 17, and a second support plate 18. The rotating motor 10 drives and connects to the rotating base plate 16. The first support plate 17 and the second support plate 18 are fixed at both ends of the rotating base plate 16 to support and fix the rangefinder adjustment platform.
[0063] Furthermore, the rangefinder adjustment platform includes an adjustment motor 19 and a laser rangefinder mounting plate 20. The adjustment motor 19 is vertically fixed to one side of the second support plate 18. One end of the laser rangefinder mounting plate 20 is rotatably connected to the first support plate 17, and the other end is driven to connect to the adjustment motor 19. The laser rangefinder 15 is fixed on the laser rangefinder mounting plate 20. The adjustment motor 19 is used to drive the laser rangefinder mounting plate 20 to rotate, thereby further adjusting the angle of the laser rangefinder 15 in the vertical plane.
[0064] A first support plate 17 and a second support plate 18 are set on the rotating chassis 10 to support and fix the laser rangefinder mounting plate 10. An adjustment motor 19 is fixed on one side of the second support plate 18 and drives the laser rangefinder mounting plate 20. The adjustment motor 19 drives the laser rangefinder mounting plate 20 to rotate, thereby adjusting the measurement angle of the laser rangefinder 15 on the laser rangefinder mounting plate 20 in the vertical plane, which further improves the measurement range and measurement convenience of the device.
[0065] In this embodiment, a grating fence and a corresponding grating probe are provided between the rotating motor and the rotating base plate, and a grating fence and a corresponding grating probe are also provided between the adjusting motor and the laser rangefinder mounting plate. These are used to obtain the relative rotation angle generated by the rotating base plate and the laser rangefinder mounting plate during the motor adjustment process, which facilitates the determination of coordinates in subsequent foundation follow-up measurements.
[0066] This embodiment also provides a specific process for leveling and measuring the device, including the following steps:
[0067] Step 1: After the concrete pouring of the tower foundation is completed, place the equipment at point O, the center pile of the foundation. Attach reflective strips to the centers of the four tower foundation bases.
[0068] Step 2: Place the device at point O, the center of the central pile, activate the tilt sensor to read the angle between the device and the horizontal plane, and transmit the measurement data to the host computer.
[0069] Step 3: The host computer controls the leveling component to move according to the measurement data. The servo motor drives the worm gear to rotate, and the rotation of the worm gear drives the meshing turbine gear to rotate, so that the worm gear fixing plate and the turbine gear fixing plate move relative to each other along the first groove until the tilt sensor on the rotating base plate detects that the measuring component is in a horizontal state, and the host computer controls the servo motor to stop.
[0070] Step 4: After the device completes the leveling action, the measurement begins. The laser sensor is turned on, and the rotating motor is controlled to drive the rotating base plate to rotate, so that the laser rangefinder measures the reflective strips arranged around the device. When the laser hits the reflective strip, the laser rangefinder receives a strong signal feedback as a stop signal.
[0071] Step 5: After the device receives the stop signal and stops, read the measured distance of the laser rangefinder and the relative rotation angle of the rotating motor and the adjusting motor at this time, and calculate the coordinates in the horizontal equipment coordinate system based on the data;
[0072] Step 6: Calculate the foundation width of the iron tower based on the above coordinates, output the calculation results to the display device, and wait for the next measurement command.
[0073] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.

The servo motor drives the worm to rotate, and the rotation of the worm drives the worm wheel that meshes with it to rotate, so that the worm fixing plate and the worm wheel fixing plate move relative to each other along the first groove until the tilt sensor on the rotating base plate detects that the measuring component is in a horizontal state, and the host computer controls the servo motor to stop. After the device completes the leveling process, the measurement begins. The laser sensor is activated, and the rotating motor is controlled to drive the rotating base plate to rotate. This allows the laser rangefinder to measure the reflective strips arranged around the device. When the laser hits the reflective strip, the laser rangefinder receives a strong signal feedback as a stop signal. When the device receives a stop signal and stops, it reads the measured distance of the laser rangefinder and the relative rotation angle of the rotating motor and the adjusting motor, and calculates the coordinates in the horizontal equipment coordinate system based on this data; The foundation and span of the iron tower are calculated based on the obtained coordinates. The calculation results are output to the display device and the system waits for the next measurement instruction.
