Description

Technical Field

[0001] This invention relates to the field of satellite navigation technology, specifically to a high-precision satellite navigation and positioning device. Background Technology

[0002] With the widespread adoption of global satellite navigation systems such as BeiDou and GNSS, high-precision satellite navigation and positioning equipment has been widely applied in various fields, including surveying and mapping, geological monitoring, smart agriculture, engineering machinery positioning, field base stations, autonomous driving, and deformation monitoring. In these applications, the equipment is often deployed outdoors for extended periods, placing stringent requirements on the installation attitude, levelness, and stability of the satellite receiver. The receiving beam and signal phase center of the satellite receiver are designed with a standard horizontal attitude as the benchmark. Any tilting or deflection of the receiver will directly lead to a decrease in satellite signal reception strength and a reduction in the signal-to-noise ratio, causing problems such as satellite loss and signal fluctuations. Especially in centimeter-level and sub-centimeter-level high-precision positioning scenarios, even a small angular shift in the receiver can produce significant attitude and phase shift errors, ultimately causing the positioning coordinates and elevation data to deviate severely from standard values, drastically reducing navigation and positioning accuracy and failing to meet the demands of high-precision operations.

[0003] Current high-precision satellite navigation and positioning devices are often placed outdoors for extended periods. Due to factors such as wind and rain, uneven foundation settlement, and loose soil, the connection between the fixed base and the ground is prone to shift. This causes the top satellite receiver to tilt in different directions and at different angles. Such tilting is a slow-forming permanent shift that is difficult for humans to detect in real time. This results in the positioning device operating in an abnormal posture for a long time, significantly reducing navigation and positioning accuracy.

[0004] To address the above problems, a high-precision satellite navigation and positioning device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision satellite navigation and positioning device. By using this device, the problem in the above-mentioned background is that the connection between the fixed base and the ground is prone to displacement, which in turn causes the top satellite receiver to tilt in different directions and angles, resulting in the positioning device working in an abnormal posture for a long time and significantly reducing the accuracy of navigation and positioning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-precision satellite navigation and positioning device includes a fixed column and a support plate fixed to the end of the fixed column. A rotating component is provided at one end of the fixed column, and a receiver body is fixedly mounted at the other end of the rotating component. A connecting component is fixedly mounted on the surface of the support plate, and a driving component is also fixedly mounted on the surface of the support plate. A pushing component is provided on one side of the driving component. An angle sensor for detecting the tilt angle of the receiver body is fixedly mounted on one side of the receiver body. A limiting plate is fixedly mounted on one side of the receiver body, and a rotating plate is rotatably connected to the surface of the limiting plate. The output end of the pushing component is slidably connected to the rotating plate, and the pushing component is used to adjust the angle between the rotating plate and the receiver body. An adsorption component is provided inside the limiting plate, and an elastic locking component is provided inside the limiting plate, which engages with the rotating plate. The adsorption component allows the elastic locking component to switch between engaging and disengaging states with the rotating plate. A connecting plate is provided on one side of the elastic locking component, and a friction component is rotatably mounted at one end of the connecting plate, and the friction component is slidably connected to the connecting component.

[0007] Furthermore, the driving component includes a circular electric slide rail and a slide base disposed on the surface of the circular electric slide rail. The circular electric slide rail is fixedly connected to the surface of the support plate, and the pushing component is fixedly connected to the slide base.

[0008] Furthermore, the pushing component includes an electric push rod and a slider fixed to the output end of the electric push rod. The electric push rod is fixedly connected to the slide block, and rollers are installed on both sides of the slider, and the rollers are tactilely connected to the rotating plate.

[0009] Furthermore, the rotating plate has two limiting grooves inside, and the roller is tactilely connected to the limiting grooves. The rotating plate also has several slots inside, and the elastic clips engage with the slots.

[0010] Furthermore, the elastic locking element includes a movable block and a locking plate fixed to one side of the movable block. The movable block and the locking plate are slidably connected to the limiting plate, and the locking plate is slidably connected to the locking groove. A spring is fixedly installed on one side of the movable block, and one end of the spring is fixedly connected to the inside of the limiting plate. Two hinge plates are fixedly installed at the bottom of the movable block, and the connecting plate is rotatably connected to the two hinge plates.

[0011] Furthermore, the adsorption component includes an electromagnet and a magnet block fixed to one side of the moving block, with the electromagnet fixedly installed inside the limiting plate.

[0012] Furthermore, the connector includes an annular disk and four support legs fixed to one side of the annular disk. The four support legs are respectively fixedly connected to a support plate. A guide groove is provided inside the annular disk, and the friction element is slidably connected to the guide groove.

[0013] Furthermore, the friction element includes an arc-shaped plate and a T-shaped plate fixed to one side of the arc-shaped plate. The connecting plate is rotatably connected to the arc-shaped plate, the T-shaped plate is slidably connected to the guide groove, and two friction pads are fixedly installed on one side of the arc-shaped plate.

[0014] Furthermore, an annular plate is fixedly installed at one end of the fixed column.

[0015] Furthermore, the rotating component includes a ball seat and a rotating head rotatably connected inside the ball seat. An annular turntable is fixedly installed on one side of the ball seat, and the annular turntable is rotatably connected to an annular plate. The rotating head is fixedly connected to the receiver body.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the electromagnetic clutch and mechanical linkage structure, it integrates two major functions: wide-range angle adjustment and automatic tilt correction. It can not only meet the azimuth angle adaptation requirements of satellite signals under different regions and working conditions, but also cope with multi-angle tilting faults caused by foundation settlement and soil loosening, greatly improving the equipment's versatility and scenario adaptability.

[0017] 2. The tilt sensor can accurately collect three-dimensional tilt and attitude data in real time, accurately identify tilt anomalies in any direction and of any magnitude, and promptly correct attitude errors and phase offset errors caused by the tilt of the receiver body, effectively improving the stability of satellite signal reception and continuously ensuring the positioning accuracy of high-precision satellite navigation.

[0018] 3. Through the linkage mechanism of unlocking and alignment and friction locking, the rotating plate can be unlocked and the receiver body can be rigidly braked and locked simultaneously when tilting and straightening. During the alignment process, only the rotating plate is adjusted circumferentially, which reduces the probability of secondary offset caused by the overall deflection of the receiver when the drive mechanism is activated.

[0019] 4. It adopts a layered independent motion structure with overall circumferential angle adjustment and local attitude fine adjustment. The two motion modes do not interfere with each other and the force is reasonable, effectively avoiding the problems of component off-center load wear and stress concentration.

[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To address the technical problem of the mounting base easily shifting at the ground connection point, causing the top satellite receiver to tilt in different directions and angles, resulting in the positioning equipment operating in an abnormal posture for extended periods and significantly reducing navigation and positioning accuracy, such as... Figures 1-9 As shown, the following preferred technical solutions are provided: like Figure 1 and Figure 2As shown, a high-precision satellite navigation and positioning device includes a fixed column 1 and a support plate 2 fixed to the end of the fixed column 1. The fixed column 1 serves as the main load-bearing base of the entire device, with high overall structural rigidity, which can stably support all upper functional components. A rotating component 4 is provided at one end of the fixed column 1, and a receiver body 5 is fixedly installed at the other end of the rotating component 4. The rotating component 4 provides rotational freedom for the receiver body 5, supporting multi-angle azimuth and attitude adjustment of the receiver body 5 to meet the angle adaptation requirements of satellite signal reception in different areas. At the same time, the rotating connection structure can adapt to attitude fine-tuning movements. A connecting component 6 is fixedly installed on the surface of the support plate 2. A driving component 7 is also fixedly installed on the surface, and a pushing component 8 is set on one side of the driving component 7. An inclination sensor 9 for detecting the tilt angle of the receiver body 5 is fixedly installed on one side of the receiver body 5. The inclination sensor 9 is directly and synchronously installed with the receiver body 5, which can collect the tilt angle and tilt direction of the receiver body 5 in real time and accurately. The detection data has no intermediate structure transmission error, and the detection accuracy is high. It realizes all-weather automatic monitoring of the tilt state, and can promptly capture various tilt anomalies caused by foundation settlement and loose fasteners, providing accurate signal basis for subsequent automatic straightening actions, eliminating the need for manual inspection mode and improving the intelligence level of the equipment.

[0024] A limiting plate 10 is fixedly installed on one side of the receiver body 5. A rotating plate 20 is rotatably connected to the surface of the limiting plate 10. The output end of the pusher 8 is slidably connected to the rotating plate 20. The pusher 8 is used to adjust the angle of the rotating plate 20 and the receiver body 5. The rotating plate 20 is rotatably connected to the limiting plate 10, giving the rotating plate 20 independent rotation capability, realizing the separation of the motion of the transmission end and the receiving end, and providing a structural premise for distinguishing between the two actions of overall angle adjustment and local alignment. An adsorption component 30 is provided inside the limiting plate 10. The tilt sensor 9, the drive component 7, the pusher 8 and the adsorption component 30 are electrically connected through a controller. The controller is existing technology and is not shown in the figure. An elastic locking component 40 is provided inside the limiting plate 10, and the elastic locking component 40 is engaged with the rotating plate 20. The adsorption component 30 can switch the engagement or disengagement state of the elastic locking component 40 and the rotating plate 20. The elastic locking component 40 and the rotating plate 20 are normally engaged, which can lock the two into a whole. At this time, the power of the pusher 8 can be completely transmitted to the receiver body 5, and a large-range angle adjustment can be successfully completed. The mechanism features a non-slip, non-slip adsorption component 30 and elastic locking component 40 forming an electric clutch mechanism. This allows for rapid switching between locking and unlocking states via electronic control, with sensitive and fast switching action. No manual operation is required, and it is compatible with automated control logic. A connecting plate 50 is located on one side of the elastic locking component 40, with a friction component 60 rotating at one end. The friction component 60 is slidably connected to the connecting component 6, enabling mechanical linkage between the elastic locking component 40 and the friction component 60. The extension and retraction of the elastic locking component 40 synchronously drives the displacement of the friction component 60, allowing the unlocking and friction locking actions to be completed simultaneously. The timing of these actions is highly matched, eliminating the need for an additional independent control mechanism and further simplifying the control logic and mechanical structure. The friction component 60 slides in conjunction with the fixed connecting component 6, generating stable friction when they are in contact. This effectively brakes and locks the limiting plate 10 and the receiver body 5. During the alignment and positioning phase, the receiver body 5's posture is fixed, preventing secondary deflection of the receiver body 5 when the pushing component 8 drives the rotating plate 20, significantly improving alignment accuracy.

[0025] Initially, the adsorption component 30 is in a power-off closed state. The elastic locking component 40 pops outward under its own elasticity, forming a stable locking engagement with the rotating plate 20. The elastic locking component 40 remains in the extended position, and the connecting plate 50 pulls the friction component 60, so that there is no large frictional resistance between the friction component 60 and the connecting component 6. The controller controls the drive component 7 to start, and the drive component 7 drives the push component 8 to produce displacement. The output end of the push component 8 slides along the surface of the rotating plate 20 and applies a thrust. Since the elastic locking component 40 locks the limiting plate 10 and the rotating plate 20 together, the rotating plate 20 cannot rotate independently relative to the limiting plate 10. The thrust will be transmitted sequentially to the limiting plate 10 and the rotating plate 20. The receiver body 5 eventually drives the rotating component 4 to rotate synchronously, realizing the overall rotation of the receiver body 5 and completing the range adjustment of azimuth and elevation angles to meet the angle adaptation requirements of satellite signal reception in different scenarios. After the adjustment is completed, the drive component 7 stops, and each component can work normally while maintaining its current attitude. When the equipment is affected by uneven settlement of the foundation and loosening of the ground soil, the fixed column 1 becomes skewed, which in turn causes the receiver body 5 to tilt. The tilt sensor 9 integrated on the receiver body 5 collects three-dimensional tilt angle and attitude angle data in real time, accurately identifies the tilt direction and tilt angle of the receiver body 5, and uploads the detection signal to the controller in real time.

[0026] When the tilt exceeds the preset allowable threshold and reduces navigation and positioning accuracy, the controller determines that the device attitude is abnormal and initiates the straightening procedure. The controller first powers on the suction component 30, which generates suction force, pulling the elastic locking component 40 inwards towards the limiting plate 10. The elastic locking component 40 disengages from the rotating plate 20, giving the rotating plate 20 the freedom to rotate relative to the limiting plate 10. Simultaneously, as the elastic locking component 40 retracts inwards, it also drives the connecting plate 50 to move. The connecting plate 50 pushes the friction component 60 towards the connecting component 6, ultimately causing the friction component 60 to fit tightly against the connecting component 6. The contact surface compression forms a stable frictional resistance, which can brake the limiting plate 10 and the receiver body 5, preventing the subsequent driving action from causing the receiver body 5 to deflect as a whole. The controller, combined with the tilt position data fed back by the tilt angle sensor 9, controls the operation of the driving component 7, which drives the pushing component 8 to move, so that the output end of the pushing component 8 drives the rotating plate 20 to rotate to the tilt position corresponding to the receiver. During this process, due to the friction locking effect between the friction component 60 and the connecting component 6, the limiting plate 10 and the receiver body 5 are fixed and stationary, and only the rotating plate 20 rotates alone, avoiding secondary displacement of the receiver body 5.

[0027] Once the rotating plate 20 is aligned, the controller de-energizes the adsorption component 30, causing the adsorption force to disappear. The elastic locking component 40 then resets outward under its own elasticity, re-engaging and locking with the rotating plate 20. Simultaneously, the reset elastic locking component 40 pulls the connecting plate 50, disengaging the friction component 60 from the connecting component 6, thus releasing the friction braking effect. Subsequently, the controller again controls the pushing component 8 to make a small movement, which, through the integrated rotating plate 20 and the limiting plate 10, drives the receiver body 5 to make a slight attitude adjustment. The tilt sensor 9 continuously monitors the attitude in real time until it detects that the receiver body 5 has returned to a standard horizontal attitude. At this point, the driving component 7 and the pushing component 8 stop moving, and the straightening process is completed.

[0028] Therefore, during the tilt correction process, the friction braking structure of the friction component 60 and the connecting component 6 forms a rigid limit on the receiver body 5. The movement of the pushing component 8 only drives the rotating plate 20 to align independently, effectively reducing the secondary offset caused by the overall rotation of the receiver body 5 due to the driving action. This structurally ensures the accuracy of attitude correction and matches the stringent requirements of high-precision satellite navigation equipment for levelness and attitude angle. Combined with the tilt sensor 9, it can accurately capture tilt in any direction and at any angle, achieving fine-tuning of the angle. It can quickly restore the receiver body 5 to the standard level state, effectively reducing attitude error and phase offset error, and ensuring the quality of satellite signal reception and positioning accuracy. Since the elastic clamp 40 locks the limiting plate 10 and the rotating plate 20 together, the movement of the pushing component 8 can drive the rotating component 4 to rotate synchronously, realizing the overall rotation of the receiver body 5 and completing the range adjustment of azimuth and pitch angles. This meets the angle adaptation requirements of satellite signal reception in different scenarios. The entire device achieves fully automated operation of tilt detection, automatic mode switching, automatic alignment, and automatic correction, without the need for manual on-site inspection or climbing for leveling. It is especially suitable for deployment scenarios that are difficult for personnel to reach, such as in the wild, remote areas, and high altitudes, which greatly reduces the workload of manual operation and maintenance and improves the efficiency of equipment operation.

[0029] like Figure 3As shown, an annular plate 11 is fixedly installed at one end of the fixed column 1. The rotating component 4 includes a ball seat 41 and a rotating head 42 rotatably connected inside the ball seat 41. A ball-joint structure is adopted, consisting of the ball seat 41 and the rotating head 42. The rotating head 42 can rotate in any direction inside the ball seat 41, possessing three-dimensional spatial swing freedom, providing a motion basis for the slight tilting and alignment of the receiver body 5 and fine-tuning of its posture. An annular turntable 43 is fixedly installed on one side of the ball seat 41, and the annular turntable 43 is rotatably connected to the annular plate 11. The annular turntable 43 and the annular plate 11 at the end of the fixed column 1 are connected... 1. A rotational fit is formed, allowing the entire ball seat 41 to rotate 360° around the fixed column 1. The rotating head 42 is fixedly connected to the receiver body 5. In the tilting and straightening condition, the adsorption component 30 moves to release the elastic clip 40, and the friction component 60 and the connecting component 6 engage and brake, locking the limit plate 10 and the circumferential position of the receiver body 5. The annular turntable 43 and the annular plate 11 are relatively stationary. At this time, only the rotating head 42 makes a slight multi-angle deflection relative to the ball seat 41. With the extension and retraction of the push component 8, the receiver body 5 is straightened and corrected with high precision, achieving accurate compensation for the tilt posture.

[0030] like Figure 4 , Figure 6 and Figure 7 As shown, the driving component 7 includes a circular electric slide rail 71 and a slide block 72 disposed on the surface of the circular electric slide rail 71. The circular electric slide rail 71 is fixedly connected to the surface of the support plate 2, and the pushing component 8 is fixedly connected to the slide block 72. During normal angle adjustment, the controller drives the circular electric slide rail 71 to rotate, causing the slide block 72 to move in a circle along the circular electric slide rail 71. The slide block 72 simultaneously carries the pushing component 8 to change its circumferential position. The pushing component 8 applies a circumferential thrust to the rotating plate 20. Due to the locking effect of the elastic locking component 40, the rotating plate 20 cannot rotate independently relative to the limiting plate 10. The thrust is transmitted sequentially to the limiting plate 10 and the receiver body 5, and finally drives the rotating component 4 to rotate, completing the 360° full circumferential azimuth angle adjustment of the receiver body 5 to meet the satellite signal reception requirements of different azimuths. After the adjustment is in place, the slide block 72 stops to maintain the current attitude.

[0031] When the receiver body 5 is tilted and automatically straightened, the tilt sensor 9 detects that the tilt of the receiver body 5 exceeds the standard. The controller first controls the adsorption component 30 to be energized, pulls the elastic clip 40 to retract, and releases its engagement with the rotating plate 20. The elastic clip 40 simultaneously drives the connecting plate 50 and the friction component 60 to move, so that the friction component 60 presses the connecting component 6, and relies on friction to lock and fix the limiting plate 10 and the receiver body 5 to prevent the whole body from rotating.

[0032] The controller, combined with the tilt azimuth data fed back by the tilt sensor 9, drives the circular electric slide rail 71 to work, and precisely controls the slide block 72 to slide along the circumference to the target position corresponding to the tilt. During this process, the receiver body 5 remains stationary, and only the slide block 72 and the pusher 8 drive the rotating plate 20 to rotate and align independently.

[0033] After alignment is completed, the adsorption component 30 is de-energized, the elastic clip 40 is reset and re-clamped onto the rotating plate 20, and the friction component 60 is disengaged from the connecting component 6; then the pusher 8 performs a telescopic action, causing the receiver body 5 to make a small attitude adjustment until the tilt sensor 9 detects that the device has returned to a horizontal state, and the straightening process ends.

[0034] like Figures 5-7 As shown, the pusher 8 includes an electric push rod 81 and a slider 82 fixed to the output end of the electric push rod 81. The electric push rod 81 is fixedly connected to the slide block 72. Rollers 83 are installed on both sides of the slider 82, and the rollers 83 are in rolling connection with the rotating plate 20. The electric push rod 81, as a linear power source, can be precisely electrically controlled to adjust its extension stroke and movement speed. It can output sufficient thrust to complete attitude correction and angle adjustment, and can also achieve fine-tuning of small strokes, which meets the accuracy requirements of attitude correction for high-precision satellite navigation devices. It can quickly correct the receiver to a standard horizontal state. The rollers 83 and the rotating plate 20 form a rolling connection, which greatly reduces the motion friction between the two compared with the traditional surface contact sliding structure. On the one hand, it reduces the driving load and the energy consumption of the electric push rod 81. On the other hand, it avoids the problem of jamming and sticking caused by hard friction, and the mechanism moves more smoothly.

[0035] The rotating plate 20 has two limiting grooves 201 inside, and the roller 83 is rolled in connection with the limiting grooves 201. The rotating plate 20 also has several slots 202 inside, and the elastic clip 40 engages with the slots 202. The limiting grooves 201 provide a rigid constraint on the rolling trajectory of the roller 83, ensuring that the roller 83 always rolls in a directional manner within the limiting grooves 201. This effectively prevents the roller 83 from shifting left or right, slipping, or derailing during the pushing and angle adjustment process. The limiting grooves 201 provide a dedicated rolling track for the roller 83. During the combined motion of the circumferential displacement of the circular electric slide rail 71 and the linear extension and retraction of the electric push rod 81, the roller 83 can roll smoothly along the limiting grooves 201, adapting to the angle changes and position deviations of the rotating plate 20. This effectively counteracts the interference stress generated by the multi-dimensional motion, ensuring smooth movement throughout the angle adjustment and posture correction process, without jamming or stagnation.

[0036] To address the technical problem that the rotating plate 20, when rotating with the pusher 8, can easily cause a secondary offset in the receiver body 5, such as... Figures 4-9 As shown, the following preferred technical solutions are provided: like Figure 7 and Figure 8As shown, the elastic locking component 40 includes a movable block 401 and a locking plate 402 fixed to one side of the movable block 401. The movable block 401 and the locking plate 402 are slidably connected to the limiting plate 10, and the locking plate 402 is slidably connected to the locking groove 202. A spring 403 is fixedly installed on one side of the movable block 401, and one end of the spring 403 is fixedly connected to the inside of the limiting plate 10. Two hinge plates 404 are fixedly installed at the bottom of the movable block 401. The connecting plate 50 is rotatably connected to the two hinge plates 404. The adsorption component 30 is not energized and has no adsorption force. The spring 403 is in a naturally extended state and pushes the movable block 401 outward along the inner slide of the limiting plate 10 by its own elastic thrust, causing the locking plate 402 to extend synchronously and embed into the locking groove 202 of the rotating plate 20, forming a reliable locking engagement. At this time, the rotating plate 20 and the limiting plate 10 are rigidly locked and cannot rotate relative to each other. The power of the pushing component 8 can... The receiver body 5 is fully transferred and adjusted in all directions using a circular electric slide rail 71. When the tilt sensor 9 detects that the receiver body 5 is tilted too much, the controller controls the adsorption component 30 to be powered on, generating an adsorption force that pulls the moving block 401 to overcome the elastic force of the spring 403 and retract into the limiting plate 10. As the moving block 401 slides, it drives the locking plate 402 to exit the locking slot 202 simultaneously. The rotating plate 20 is released from the locking constraint with the limiting plate 10, and the rotating plate 20 gains independent rotational freedom. During the inward retraction of the moving block 401, the two hinge plates 404 at its bottom are displaced synchronously. Through the hinge transmission, the connecting plate 50 is moved horizontally, which in turn pushes the friction component 60 to press the connecting component 6 on the support plate 2. The limiting plate 10 and the receiver body 5 are locked and fixed by friction. At this time, only the rotating plate 20 can rotate and be aligned with the pushing component 8, effectively preventing the receiver body 5 from shifting again.

[0037] The adsorption component 30 includes an electromagnet 301 and a magnet 302 fixed to one side of the moving block 401. The electromagnet 301 is fixedly installed inside the limiting plate 10. When the electromagnet 301 is energized, it can precisely pull the magnet 302 and the moving block 401 back, simultaneously completing the unblocking action and linking the friction locking mechanism for braking. After the electromagnet 301 is de-energized and demagnetized, the adsorption force disappears. With the spring force of the spring 403, the snap-lock is automatically reset and the friction lock is released. The adsorption force can be quickly generated or eliminated by energizing or de-energizing the electromagnet 301, precisely driving the moving block 401 to slide, completing the unblocking and reset snap-locking action between the card plate 402 and the card slot 202, realizing the rapid switching between the device posture straightening mode and the angle adjustment mode. The action response speed is fast and the control precision is high.

[0038] like Figure 4 , Figure 7 and Figure 9As shown, the connector 6 includes an annular disk 61 and four support legs 62 fixed to one side of the annular disk 61. The four support legs 62 are fixedly connected to the support plate 2. The annular disk 61 has a guide groove 63 inside, and the friction element 60 is slidably connected to the guide groove 63. It is fixedly connected to the support plate 2 through the four support legs 62. Compared with a single-point, single-sided fixed structure, the four-point support forms a symmetrical and stable support structure with uniform force and high support rigidity. It can effectively prevent the annular disk 61 from shaking, shifting or slightly deforming during long-term friction braking, ensuring that the overall position of the annular disk 61 is always fixed, providing a stable and unchanging installation reference for the braking cooperation of the friction element 60, and ensuring long-term stability of locking accuracy.

[0039] Friction component 60 includes an arc-shaped plate 601 and a T-shaped plate 602 fixed to one side of the arc-shaped plate 601. Connecting plate 50 is rotatably connected to the arc-shaped plate 601, and T-shaped plate 602 is slidably connected to the guide groove 63. Two friction pads 603 are fixedly installed on one side of the arc-shaped plate 601. When the tilt sensor 9 detects that the receiver body 5 tilts excessively, the electromagnet 301 is energized to attract the magnet block 302, pulling the moving block 401 to retract inward against the elastic force of the spring 403. Simultaneously, this causes the bottom hinge plate 404 and connecting plate 50 to shift. Because the connecting plate 50 is rotatably connected to the arc-shaped plate 601, it can adaptively swing at an angle, pushing the entire arc-shaped plate 601 towards the inner side of the guide groove 63. Simultaneously, the T-shaped plate 602 is embedded in the guide groove 63 for sliding limit, ensuring that the sliding trajectory of the arc plate 601 is accurate and does not deviate. Finally, the two friction pads 603 on the outer side of the arc plate 601 are tightly pressed against the groove wall of the guide groove 63. Relying on the squeezing friction between the friction pads 603 and the guide groove 63, a circumferential locking brake is formed on the limit plate 10 and the receiver body 5, keeping the receiver body 5 in a fixed and stationary state. At this time, when the circular electric slide rail 71 drives the slide block 72 and the electric push rod 81 to move circumferentially, it can only drive the rotating plate 20 to rotate independently relative to the limit plate 10, and will not cause the receiver body 5 to deflect as a whole, thus completely avoiding secondary positional deviation during the straightening process.
