Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of measuring equipment, and specifically relates to a measuring system based on electric tripod. BACKGROUND

[0002] In the field of construction, construction measurement is applied to the entire construction process, from site leveling, building positioning, foundation construction, to building component installation, etc. Construction measurement is required. In the prior art, a measuring system composed of a tripod, a laser instrument (or laser instrument, laser equipment, etc., including a laser level, a laser leveling instrument, and a laser line projector, etc.) and a receiver (or laser receiver) is usually used for high-precision measurement of distance, height or shape. Among them, the tripod serves as the supporting structure of the entire system, used to fix the laser instrument and / or the receiver, ensuring that they maintain a stable position and attitude during measurement to ensure the accuracy of the measurement; the laser instrument is used to emit one or more laser beams, which have high directionality and stability. By adjusting the angle and position of the laser instrument, the laser beam can be directed to the target object or reference point that needs to be measured in height; the receiver is mainly used to receive the laser signal emitted by the laser instrument, and usually gives a corresponding prompt when receiving the laser signal, such as a sound or light prompt.

[0003] In the prior art, an electric tripod is usually used for measurement work, and to facilitate operation, the existing electric tripod is usually also provided with a remote controller, so that the measurer can remotely control the electric tripod through the remote controller. For example, the measuring device disclosed in Chinese patent CN216432949U is controlled by a remote controller. In practice, when the measurer sees or hears the prompt of the receiver, the electric tripod can be stopped by the remote controller to achieve the purpose of measurement or calibration. For example, when measuring or calibrating height, the tripod is usually placed in the appropriate position and leveled first, and then the laser instrument for generating laser is installed on the top of the lifting component of the tripod, as shown in FIG. Figure 1 At the same time, the receiver is set at the position to be measured or calibrated. At this time, the receiver can be set on another tripod, or on the object to be measured on the wall or shelf on site, and at this time, the receiver is usually located away from the laser instrument, as shown in FIG. Figure 1The measuring personnel can hold the remote controller and stand close to the receiver during the measurement, the measuring personnel can control the lifting component in the tripod to lift through the remote controller, so as to adjust the position of the laser instrument in the vertical direction, so that the laser projected by the laser instrument gradually approaches the receiver, when the detector of the receiver receives the laser, the receiver starts to alarm intermittently to remind the measuring personnel, when the receiver starts to alarm continuously, it indicates that the laser has reached the predetermined position, at this time, the measuring personnel controls the lifting component in the tripod to stop lifting through the remote controller, and the position of the laser instrument does not change any more, so as to achieve the purpose of measurement or calibration.

[0004] The existing measurement method not only needs the measuring personnel to judge whether the laser instrument reaches the predetermined position, but also needs manual operation of the remote controller to stop the lifting action of the tripod, the measurement precision is affected by the experience and reaction speed of the measuring personnel, which greatly affects the measurement precision, leads to low measurement precision, and the measurement process depends on manual operation, which leads to complicated measurement process; in addition, the prompt module in the existing receiver is more complex (for example, the above-mentioned intermittent alarm and then continuous alarm), so as to better prompt the measuring personnel, therefore, how to complete the measurement or calibration work more conveniently, more accurately and at lower cost is urgent to be solved.

[0042] Embodiment 1

[0043] The embodiment provides a measurement system based on the motorized tripod 1, which comprises the motorized tripod 1, the receiver 9 and the laser instrument 8 for generating laser, wherein, as shown in Figure 4 and Figure 5 The receiver 9 comprises the processor 93 and the detector 94 for detecting laser, and the detector 94 is connected with the processor 93. In the implementation, the processor 93 can adopt an existing control circuit or micro processing (such as embedded chip, etc.) or PLC, etc., and the detector 94 can adopt the detector 94 for detecting laser in the prior art, which will not be described here. In the implementation, the receiver 9 usually further comprises the shell 91, as shown in Figure 4 The shell 91 is configured with the window 92 for detecting the detector 94, the processor 93 and the detector 94 are arranged in the shell 91, and the detector 94 corresponds to the window 92. Of course, in the implementation, the receiver 9 further comprises the battery 62 arranged in the shell 91, so as to power the electrical devices such as the processor 93 and the detector 94 in the receiver 9 by the battery 62.

[0044] In the embodiment, the electric tripod 1 can be a conventional electric tripod 1. As an example, the electric tripod 1 comprises a controller 41, a lifting component 24 for supporting the laser instrument 8, a motor 3 in driving connection with the lifting component 24, a base 2, and a plurality of telescopic legs 23, as shown in Figure 2 and Figure 3 Each of the legs 23 is rotatably connected to the base 2 for folding or unfolding the legs 23. In practice, the legs 23 can be conventional telescopic legs 23. In practice, each of the legs 23 is evenly distributed along the circumference of the base 2 for more stable and reliable support of the base 2. The number of the legs 23 can be determined according to actual needs, for example, three legs 23, four legs 23, or five legs 23, as shown in Figure 2 In the embodiment, the base 2 is connected with three legs 23, which are evenly distributed along the circumference of the base 2.

[0045] In practice, the controller 41 can be a conventional control circuit or a microprocessor (such as an embedded chip) or a PLC, and similarly, in practice, the lifting component 24 can also be a rod-shaped structure. In order to reduce the weight, in practice, the lifting component 24 can preferably be a long strip-shaped structure for lifting in a larger range; for example, in practice, the lifting component 24 can be a solid rod or a hollow sleeve structure, as shown in Figure 2 and Figure 3 which is conducive to reducing the weight of the lifting component 24 and improving stability.

[0046] In practice, the base 2 can be an integrally formed component or a combined component composed of a plurality of parts, as shown in Figure 2 and Figure 3 In practice, the base 2 is configured with an adapter hole 21 extending through the upper and lower ends, the size of the adapter hole 21 being greater than the size of the lifting component 24, so that the upper end of the lifting component 24 can extend above the base 2 through the adapter hole 21, as shown in Figure 2 In order to facilitate the connection of the laser instrument 8, the top of the lifting component 24 is also provided with a gimbal 25, as shown in Figure 2 so as to connect the laser instrument 8 through the gimbal 25, which is very convenient.

[0047] In practice, the motor 3 is in driving connection with the lifting component 24, so as to drive the lifting component 24 to perform lifting action by the motor 3, thereby achieving the purpose of driving the laser instrument 8 to vertically lift and adjusting the position of the laser instrument 8 along the vertical direction, which is more convenient for cooperation with the receiver 9.

[0048] In the system provided in the embodiment, the receiver 9 further comprises a first communication module 95, as shown in Figure 4 and Figure 5As shown, the first communication module 95 is connected with the processor 93, so that the receiver 9 can at least send signals outwardly through the first communication module 95; correspondingly, the motorized tripod 1 further comprises a second communication module 42 adapted to the first communication module 95, such as Figure 2 and Figure 5 As shown, the second communication module 42 is connected with the controller 41, so that the motorized tripod 1 can at least receive signals through the second communication module 42. In actual use, the first communication module 95 and the second communication module 42 are in communication connection, so that the receiver 9 and the motorized tripod 1 can communicate with each other. In actual use, when the detector 94 of the receiver 9 detects a laser, the receiver 9 can send a signal (including a stop signal during leveling, lowering or finding) to the motorized tripod 1 through the cooperation of the first communication module 95 and the second communication module 42. After receiving the signal, the motorized tripod 1 can control the motor 3 to stop rotating in time according to the prior setting, so that the laser instrument 8 stops rising and falling, thereby achieving the purpose of measurement or calibration. With such a design, the receiver 9 can automatically control the motorized tripod 1 to stop during measurement. On the one hand, this process does not require manual intervention, which not only makes the measurement process simpler and more convenient, but also ensures that the measurement accuracy is not affected by personnel experience and reaction speed, so that the stopping position of the laser instrument 8 is more accurate, which is beneficial to ensure and improve the measurement accuracy. On the other hand, the process from detecting a laser signal to the controller 41 controlling the motor 3 to stop is automatically completed by the cooperation of the receiver 9 and the motorized tripod 1. Not only is the response speed significantly higher than manual control, thereby significantly improving the measurement accuracy, but also the entire measurement process takes less time, which is beneficial to improve the measurement efficiency. In addition, the design also does not need to configure a complex prompting module in the receiver 9 to remind the measurement personnel, thereby effectively simplifying the structure of the receiver 9, which is beneficial to reduce the cost.

[0049] In implementation, the first communication module 95 and the second communication module 42 have various cooperation implementation modes. As an example, the first communication module 95 can comprise a wireless communication module, and correspondingly, the second communication module 42 comprises a wireless communication module adapted to the first communication module 95. By adopting mutually adapted wireless communication modules for the first communication module 95 and the second communication module 42, it is not necessary to configure a communication line at the measurement site, which not only makes the use of the system simpler and more convenient, but also enables the receiver 9 to be free of the weight of the communication line, so that the receiver 9 can be more flexibly arranged at the position to be measured or calibrated. In implementation, the wireless communication module has various implementation modes, for example, the wireless communication module can comprise a Bluetooth module or a Wi-Fi module or a ZigBee module or a LoRa module or an NB-IoT module or a 4G communication module or a 5G communication module, etc. The first communication module 95 can be arranged in the housing 91.

[0050] As another example, in implementation, the first communication module 95 can include a wired communication module, and the second communication module 42 includes a wired communication module adapted to the first communication module 95. By using the mutually adapted wired communication modules in the first communication module 95 and the second communication module 42, the measurement field receiver 9 and the motorized tripod 1 can be connected through a communication line, which is particularly suitable for harsh field environments and large electromagnetic interference, and can achieve more stable and less delayed signal transmission in the field, which is conducive to improving the measurement accuracy and meeting the measurement requirements of different occasions, and can effectively improve the versatility of the system. In implementation, the wired communication module has various implementation modes, for example, the wired communication module can include an Ethernet module or a serial communication module or a CAN bus module or a fiber communication module, etc. In order to facilitate field wiring, in a further implementation, the wired communication module further includes a communication interface for connecting the communication line. In implementation, the communication interface in the receiver 9 can be constructed on the shell 91 of the receiver 9, and the communication interface in the motorized tripod 1 can be arranged at the foot base 2 or the shell 6 of the motorized tripod 1, so as to quickly connect the communication line in the field, which is very convenient. Of course, it can be understood that the communication line is adapted to the type of the wired communication module, for example, when the wired communication module adopts a fiber communication module, the communication interface can be a fiber interface, and the communication line is a fiber line. For another example, when the wired communication module adopts a serial communication module, the communication interface can be an RS-485 interface, and the communication line is a twisted pair line.

[0051] In implementation, the laser instrument 8 can adopt a laser instrument 8 capable of emitting laser (including laser beam or laser plane) in the prior art, including but not limited to a laser level, a laser screed instrument, and a laser line projector, etc., and the laser instrument 8 is installed on the motorized tripod 1, specifically installed on the holder 25 at the top of the lifting component 24, so that the position of the laser instrument 8 in the vertical direction can be adjusted by the motorized tripod 1.

[0052] In order to achieve the transmission connection between the motor 3 and the lifting component 24, in implementation, there are various implementation modes, for example, the motorized tripod 1 further includes a transmission mechanism, the motor 3 is in transmission connection with the transmission mechanism, and the transmission mechanism is in transmission connection with the lifting component 24, so that the lifting component 24 can be driven to vertically lift by the motor 3. More specifically, as shown in Figure 2 , in this embodiment, the transmission mechanism includes a worm 31 rotatably arranged in the shell 6, a turbine 32 rotatably arranged, and a rack 241 adapted to the turbine 32, the lifting component 24 is vertically constrained in the shell 6, and the rack 241 is vertically arranged outside the lifting component 24 and is in meshing connection with the turbine 32, as shown in Figure 2 and Figure 3As shown, the worm 31 is engaged with the turbine 32, and the motor 3 is drivingly connected with the worm 31, so that the motor 3 can drive the lifting component 24 to vertically lift. The specific transmission mechanism can refer to the electric tripod 1 disclosed in the Chinese patent CN 203309468 U, which will not be repeated here.

[0053] In a more perfect embodiment, a battery 62 is further arranged in the housing 6, as shown in Figure 2 The battery 62 is used to power the motor 3, the controller 41, the second communication module 42 and other electrical devices in the electric tripod 1. In practice, the battery 62 is preferably a lithium battery 62.

[0054] For the convenience of operation, in a further embodiment, the housing 6 is further provided with an operation component 63, as shown in Figure 5 The operation component 63 is connected with the controller 41, so that the tester can control whether the battery 62 supplies power and / or the motor 3 starts and stops through the operation component 63, which is very convenient. In practice, the operation component 63 can include a button or a knob or a touch screen arranged on the housing 6.

[0055] Embodiment 2

[0056] To further improve the measurement accuracy, the main difference between the embodiment 2 and the above-mentioned embodiment 1 is that, in the measurement system based on the electric tripod 1 provided in the embodiment, the transmission mechanism between the motor 3 and the lifting component 24 is different. Specifically, in the embodiment, the transmission mechanism in the electric tripod 1 includes a screw nut transmission mechanism, as shown in Figures 6-12 The screw nut transmission mechanism includes a screw rod 34 and a nut 35. The screw rod 34 is configured with external threads, and the nut 35 is configured with a threaded hole 351 adapted to the screw rod 34, and the nut 35 is threadedly connected to the screw rod 34 through the threaded hole 351, as shown in Figure 10The lifting component 24 is connected to the nut 35 to be lifted synchronously with the nut 35. The motor 3 is in driving connection with the screw rod 34 to drive the screw rod 34 to rotate through the motor 3, and then drive the nut 35 and the lifting component 24 to vertically lift synchronously along the screw rod 34, and finally drive the gimbal 25 to vertically lift. In the embodiment, the screw rod nut transmission mechanism is arranged in the electric tripod 1, and the motor 3 is in driving connection with the lifting component 24 through the screw rod nut transmission mechanism, so that the motor 3 can drive the lifting component 24 to vertically lift through the screw rod nut transmission mechanism. Not only the purpose of adjusting the position of the laser instrument 8 in the vertical direction can be achieved, but also compared with the traditional gear and rack transmission mechanism, the screw rod nut transmission mechanism arranged in the electric tripod 1 can effectively improve the transmission precision, thereby being conducive to improving the measurement precision, and being conducive to automatically reversing and self-locking after reaching the target position, so as to ensure that the laser instrument 8 can be more stably and reliably kept at the target position, thereby being conducive to realizing more stable and reliable measurement.

[0057] More specifically, as shown in Figures 6-12 , the electric tripod 1 further comprises a suspension assembly 5 and a housing 6 with an inner cavity 61.

In assembly, the upper end of the suspension assembly 5 is connected to the foot base 2, as shown in Figure 6 and Figure 9 , and the adapter hole 21 is in communication with the internal cavity 51. The screw rod 34 and the nut 35 are arranged in the internal cavity 51, so that the lower end of the lifting component 24 can extend into the internal cavity 51 through the adapter hole 21 and be connected to the nut 35 in the internal cavity 51, as shown in Figure 6 and Figure 9 . At the same time, the upper end of the lifting component 24 can extend above the foot base 2 through the adapter hole 21 to support the gimbal 25 above the foot base 2. In implementation, the suspension assembly 5 can be an integrally formed member, for example, the suspension assembly 5 comprises a cylindrical outer sleeve 52, and the internal cavity 51 is formed in the outer sleeve 52, as shown in Figure 9 . The upper end of the outer sleeve 52 is connected to the foot base 2, and the outer sleeve 52 can be an integrally formed tubular profile. In implementation, the suspension assembly 5 can also be composed of multiple components to be segmented and formed or processed, for example, the suspension assembly 5 comprises a cylindrical outer sleeve 52 and a butt joint cylinder 53 connected to the lower end of the outer sleeve 52, as shown in Figures 6-9 . The motor 3 can be mounted on the butt joint cylinder 53, and the butt joint cylinder 53 can be connected to the lower end of the outer sleeve 52 by fasteners 72. The outer sleeve 52 and the butt joint cylinder 53 jointly form the internal cavity 51, as shown in Figure 9 . This facilitates the separate manufacture of the outer sleeve 52 and the butt joint cylinder 53, and facilitates the installation and removal of the motor 3.

[0058] In the embodiment, the central axis of the suspension assembly 5 is coaxial with the central axis of the inner cavity 51, and the central axis of the inner cavity 51 is coaxial with the central axis of the fitting hole 21, which is more conducive to ensuring that the center of gravity of the entire electric tripod 1 is located at the geometric center of the electric tripod 1, thereby improving the stability of the electric tripod 1.

[0059] In the embodiment, the shell 6 is connected to the suspension assembly 5 and suspended below the suspension assembly 5, as shown in Figures 6-9 The inner cavity 61 in the shell 6 is in communication with the inner cavity 51, which is convenient for assembly and wiring, etc. In the embodiment, the inner cavity 61 in the shell 6 is mainly used to accommodate related electronic devices, for example, the controller 41 is arranged in the inner cavity 61 in the shell 6, as shown in Figure 9 and Figure 12 The second communication module 42 can be arranged in the suspension assembly 5 or in the shell 6, which is convenient for installation and arrangement of the second communication module 42, and makes the second communication module 42 farther away from the laser instrument 8 above, effectively avoiding interference of the laser instrument 8 with communication of the second communication module 42, and is conducive to more stable communication. In the embodiment, the motor 3 can be arranged in the suspension assembly 5 or in the shell 6, or part of the motor 3 is arranged in the suspension assembly 5 and the remaining part is arranged in the shell 6, as shown in Figure 9 This is conducive to saving space, making the structure of the entire electric tripod 1 more compact, and is convenient for assembly and wiring operation. In addition, the position of the motor 3 is lower, which is conducive to more stable electric tripod 1.

[0060] As shown in Figures 6-9 In the preferred embodiment, the motor 3 is suspended in the suspension assembly 5, and the output shaft of the motor 3 is coaxial with the screw rod 34, so that the motor 3 is located away from the foot base 2, and the center of gravity of the entire electric tripod 1 is lowered, thereby improving the stability of the electric tripod 1. By coaxially arranging the output shaft of the motor 3 and the screw rod 34, the stability of the screw rod 34 during rotation is improved, and higher-precision transmission is achieved, which is conducive to automatic measurement function. In the embodiment, the motor 3 can be fixed to the lower end of the suspension assembly 5, as shown in Figure 9 The lower end of the lifting component 24 is connected to the nut 35, which is more convenient for installation and disassembly.

[0061] As an example, in the specific embodiment, the screw rod 34 is arranged in the suspension assembly 5 and coaxial with the suspension assembly 5, and the screw rod 34 is connected to the suspension assembly 5 through a bearing 71, as shown in Figure 9 The upper end of the screw rod 34 can extend to a position close to the foot base 2, and the lower end of the screw rod 34 can be connected to the output shaft of the motor 3 through a transmission mechanism such as a flange or a shaft coupling 33, as shown inFigure 9 As shown; the motor 3 can be detachably connected to the suspension assembly 5 (e.g., outer sleeve 52 or docking sleeve 53) via fasteners 72 such as bolts or screws; as Figure 9 As shown, the housing 6 can be detachably connected to the lower end of the suspension assembly 5 (e.g., outer sleeve 52 or docking sleeve 53) via fastener 72. In implementation, the housing 6 can be a one-piece molded component. In this case, the housing 6 is constructed with a threaded hole 351, and the lower end of the suspension assembly 5 is constructed with an external thread, so that the housing 6 can be suspended from the suspension assembly 5 through the engagement of the threaded hole 351 and the external thread. In implementation, the housing 6 can also be composed of at least two sub-housings 6, for example, as... Figure 9 and Figure 12 As shown, the housing 6 includes two sub-housings 6 spaced apart and opposite to each other. The two sub-housings 6 are connected together by fasteners 72 and also fit snugly against the lower end of the suspension assembly 5, as shown. Figure 9 and Figure 12 As shown.

[0062] To prevent the nut 35 from rotating synchronously with the lead screw 34, various implementations are possible. For example, in one implementation, the cross-section of the internal cavity 51 in the suspension assembly 5 can be constructed as a square. Correspondingly, the nut 35 is constructed to fit the square shape of the internal cavity 51. The nut 35 and the suspension assembly 5 form a vertical sliding pair, so that the nut 35 can only move vertically up and down under the drive of the motor 3, and will not rotate synchronously with the lead screw 34. In a preferred embodiment, the suspension assembly 5 is also provided with a guide portion 54 for limiting the rotation of the nut 35. For example, the guide portion 54 can be constructed vertically on the inner surface of the outer sleeve 52. Figures 9-11 As shown; correspondingly, the nut 35 is constructed with a limiting part 352 adapted to the guide part 54. During assembly, the nut 35 can form a moving pair along the height direction with the suspension assembly 5 through the cooperation of the guide part 54 and the limiting part 352. Figures 9-11 As shown, this not only guides the movement of the nut 35, ensuring it moves strictly vertically, thus improving measurement accuracy, but also, through the cooperation of the guide part 54 and the limiting part 352, prevents the nut 35 from rotating synchronously with the lead screw 34. In this case, the cross-section of the internal cavity 51 in the suspension assembly 5 can be constructed as a circle, and the suspension assembly 5 can preferably be constructed as a cylindrical structure, such as... Figures 9-11 As shown.

[0063] In practice, the guide portion 54 and the limiting portion 352 can be implemented in various ways. For example, the guide portion 54 can be a guide protrusion, such as... Figures 9-11 As shown, the guide protrusion is arranged along the length of the suspension assembly 5. Correspondingly, the limiting part 352 is a limiting groove adapted to the guide protrusion. The limiting groove is constructed on the outer side of the nut 35, as shown. Figures 9-11As shown, the guiding protrusion is clamped in the limiting groove, and forms a moving pair with the limiting groove. In this embodiment, the structure is simpler, and the guiding part 54 and the suspension assembly 5 can be integrally formed, which is more conducive to manufacturing and ensuring accuracy.

[0064] To improve the transmission accuracy of the lead screw 34, in a further mode, the lifting component 24 can include an inner cylinder 242 and an outer cylinder 243 connected to the inner cylinder 242, as shown in Figures 9-11 As shown, the inner cylinder 242 is coaxial with the outer cylinder 243, and the lower end of the inner cylinder 242 or the outer cylinder 243 is connected to the nut 35. The inner diameter of the inner cylinder 242 is slightly larger than the lead screw 34, so that the lead screw 34 is inserted into the inner cylinder 242 and can move relatively, so as to effectively constrain and limit the lead screw 34 by the inner cylinder 242, avoiding large amplitude shaking or swinging of the upper end of the lead screw. The outer diameter of the outer cylinder 243 can be configured to fit the inner cavity 51, so that the outer cylinder 243 forms a moving pair with the suspension assembly 5 in the vertical direction, so as to maintain the lifting component 24 in a vertical state at all times by the suspension assembly 5. The outer diameter of the outer cylinder 243 can also be configured to fit the fitting hole 21, so that the outer cylinder 243 forms a moving pair with the fitting hole 21 in the vertical direction, so as to guide the movement of the lifting component 24 by the fitting hole 21, which is conducive to maintaining the lifting component 24 in a vertical state at all times. In addition, the outer diameter of the outer cylinder 243 can also be configured to fit the guide 22 installed in the fitting hole 21, as shown in Figures 6-9 As shown, the outer cylinder 243 forms a moving pair with the guide 22 in the vertical direction, so as to guide the movement of the lifting component 24 by the guide 22, which is conducive to maintaining the lifting component 24 in a vertical state at all times. In implementation, the guide 22 can use an existing guide 22, which will not be described here.

[0065] In this embodiment, the housing 6 is also configured with an opening and a cover member 65 fitted to the opening, as shown in Figure 9 and Figure 12 As shown, correspondingly, the housing 6 is also configured with a mounting cavity 64, and the battery 62 can be arranged in the mounting cavity 64, so as to power the electrical devices such as the controller 41, the motor 3 and the second communication module 42 by the battery 62. The cover member 65 is used to close the opening, for example, the member can be fixed to the housing 6 by a fastener 72, so that external power supply is not required during on-site use, making the measurement process simpler and more efficient. By configuring the mounting cavity 64, the opening and the cover member 65, it is not only conducive to protecting the battery 62, but also convenient to replace the battery 62.

[0066] In this embodiment, the operating component 63 can be arranged on one side of the housing 6, as shown in Figures 6-9 As shown, the operating component 63 is at a lower position, which is more convenient for personnel to operate.

[0067] In the embodiment, the motor 3 can preferentially adopt a planetary motor 3. In the electric tripod 1 provided in the embodiment 1, the motor 3 drives the lifting component 24 to lift through the meshing transmission of the worm 31, the turbine 32 and the rack 241, but in the implementation, there are problems of large volume, poor transmission precision, low thrust and high manufacturing cost, while in the electric tripod 1 provided in the embodiment, the motor 3 drives the lifting component 24 to lift through the transmission of the screw nut mechanism, compared with the existing electric tripod 1 (or the electric tripod 1 in the embodiment 1), the electric tripod 1 provided in the embodiment has advantages of smaller volume, larger thrust, significantly improved transmission precision, greatly reduced manufacturing cost and the like, so that the transmission precision and stability of the measurement system based on the electric tripod 1 are significantly improved, the manufacturing cost is greatly reduced, and the market demand is better met.

[0068] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application.
