Technical Field
[0001] The present invention relates to the technical field of berth construction bed flatness monitoring, and specifically to a monitoring device and method for the construction of a wharf berth project. Background Art
[0002] After underwater rubble bed blasting ramming, backfilling, additional ramming and leveling are required to meet the requirements for caisson installation. The acceptance of its flatness is of great significance for ensuring the project quality. The allowable deviation value for bed leveling is ±50 mm. However, due to the particularity of the underwater environment, traditional bed leveling acceptance devices often have problems such as insufficient accuracy and complex operation, and are difficult to meet the needs of modern wharf projects.
[0003] In the prior art, when measuring the deviation degree, a stable reference plane is required. The deviation is obtained by measuring multiple points on the bed and comparing with the reference plane. For example, an engineering ship is used as the reference plane for operation and comparison. However, the engineering ship on the sea level itself is not a good reference plane, and is greatly affected by tides and wind interference;
[0004] The present invention provides a monitoring device for bed flatness, which can directly compare multiple points on the bed without the need for an extra reference plane for calibration, and can more effectively and directly obtain the flatness parameters of the bed.
[0005] Therefore, in view of the above problems, a monitoring device and method for the construction of a wharf berth project are proposed. Summary of the Invention
[0006] The purpose of the present invention is to provide a monitoring device and method for the construction of a wharf berth project, which can directly compare multiple points on the bed without the need for an extra reference plane for calibration, and can more effectively and directly obtain the flatness parameters of the bed.
[0007] To achieve the above purpose, the present invention provides the following technical solution: A monitoring device for the construction of a wharf berth project, including a central column and an engineering ship. On both sides of the central column, there are first cross plates rotatably connected through hinges. A second cross plate is slidably connected to the first cross plate. The first cross plate and the second cross plate are parallel. Screws are rotatably connected to the inner sides of the first cross plate and the second cross plate. Sliders are helically connected to the outer sides of the screws. Waterproof motors are fixedly connected to the inner sides of the first cross plate and the second cross plate. The output ends of the waterproof motors are fixedly connected to the corresponding screws. The slider in the first cross plate is fixedly connected to one end of the second cross plate. The slider in the second cross plate is fixedly connected to a support plate. A moving roller is rotatably connected to the bottom end of the support plate. The moving roller can slide on the bed;
[0008] During the process of the moving roller sliding on the foundation bed, the inclination degrees of the first cross plate and the second cross plate will continuously change. By obtaining the change values of the inclination degrees of the first cross plate and the second cross plate, the flatness value of the foundation bed can be obtained.
[0009] Under the above settings, the present invention can directly compare multiple points on the foundation bed without the need for an extra reference plane for calibration, and can more effectively and directly obtain the flatness parameters of the foundation bed and increase the accuracy of monitoring. The first cross plate in the present invention is symmetrically arranged, and the support plates and the moving rollers on both sides move synchronously to cancel out the pulling forces on the left and right sides and increase the stability during the monitoring process;
[0010] The present invention directly converts the height change of the foundation bed into continuous inclination degree changes, directly compares the corresponding inclination degree values at each foundation bed position, greatly increases the accuracy during the monitoring process, and avoids the uncontrollable reference plane problem; the moving roller in the present invention is internally provided with a counterweight block to increase the fitting degree between the moving roller and the foundation bed;
[0011] Preferably, as a monitoring device for wharf berth engineering construction of the present invention, the bottom end of the central column is fixedly connected with a bottom plate, the middle position of the bottom end of the bottom plate is fixedly connected with a support rod, and the outer edge of the bottom end of the bottom plate is fixedly connected with an inclined hydraulic rod. The bottom plate is supported by the bottom end of the support rod and the movable end of the hydraulic rod abutting against the foundation bed.
[0012] Under the above settings, the bottom ends of the bottom end of the support rod and the movable end of the hydraulic rod can be provided with spiky shapes to further increase the stability. The present invention mainly realizes the monitoring of flatness through the comparison of inclination degrees. Even if the bottom plate undergoes a slight displacement, the interference with the result of the inclination degree comparison will not be large;
[0013] Preferably, as a monitoring device for wharf berth engineering construction of the present invention, a water pump is fixedly connected to the top end of the central column, a drainage tray is fixedly connected to the top end of the water pump, and the water suction pipes at the input end of the water pump are arranged on the left and right sides of the water pump. When the water pump works, water is pumped by the water suction pipes on both sides and drained by the drainage tray at the top end to provide a continuous downward pressure for the bottom plate to increase the stability of the bottom plate.
[0014] Under the above settings, a water pump is provided in the present invention. When the water pump works, it can provide a continuous downward pressure for the bottom plate to increase the stability of the bottom plate;
[0015] Preferably, as a monitoring device for wharf berth engineering construction of the present invention, a connecting rod is fixedly connected to the center of the top end of the drainage tray, and a connecting rope is fixedly connected to the top end of the connecting rod. By retracting and releasing the connecting rope, the recovery of the central column is realized. The connecting rope can be bound to the unloaded electric wire to realize power supply;
[0016] Preferably, as the monitoring device for dock berth engineering construction of the present invention, chutes are provided inside both the first cross plate and the second cross plate. The chutes are in a closed state. A driven block is slidably connected inside the chutes. The driven block is made of a magnet material and forms a magnetic attraction structure with the slider. When the slider moves, the driven block will slide synchronously. A potentiometer distributed horizontally is embedded inside the chutes. The driven block slides on the potentiometer to determine the positions of the driven block and the moving roller.
[0017] With the above settings, by providing the driven block and the potentiometer, etc., the positions of the driven block and the moving roller can be obtained. The transmission ratio of the continuously variable transmission is changed through this position and is used to judge the progress of the monitoring operation.
[0018] Preferably, as the monitoring device for dock berth engineering construction of the present invention, a driving wheel is fixedly connected to the rotating shaft of the first cross plate. Measuring boxes are fixedly connected to the outer sides of the left and right ends of the central column. A continuously variable transmission is fixedly connected inside the measuring boxes. The input shaft of the continuously variable transmission passes through the measuring box and is fixedly connected to a driven wheel. The driven wheel and the driving wheel are driven by a transmission belt. The output shaft of the continuously variable transmission is fixedly connected to a balance plate. An inclination sensor is fixedly connected to the balance plate. During the process of the moving roller sliding on the bed, the inclination changes of the first cross plate and the second cross plate are obtained through the inclination sensor.
[0019] Preferably, as the monitoring device for dock berth engineering construction of the present invention, a memory for storing the inclination data obtained by the inclination sensor is fixedly connected to the top of the measuring box.
[0020] During use, the monitoring device is moved to the middle position of the bed by an engineering ship, and then the monitoring device is lowered onto the bed through the traction mechanism on the engineering ship. During monitoring, first, the slider on the first cross plate is made to approach the central column. After the slider on the first cross plate moves to the limit position of the stroke, the slider on the second cross plate is made to approach the central column. During the movement of the slider, the moving roller will continuously move on the bed. The provided potentiometer obtains the position of the moving roller in real time, and the inclination degrees of the first cross plate and the second cross plate will continuously change;
[0021] When the support plate is at the end position of the second horizontal plate, when the moving roller travels on the foundation bed, due to the relatively long lever arm, the change in the perpendicularity of the foundation bed acting on the change in the inclination angle of the second horizontal plate will not be sensitive enough. During the process of the support plate moving towards the central column, the continuously variable transmission is used to increase the speed, the lever arm gradually shortens, and the transmission ratio of the continuously variable transmission gradually decreases. When the support plate reaches the midpoint of the first horizontal plate, the measurement ends. At this time, the transmission ratio of the continuously variable transmission reaches 1:1, which is used to play a role in compensating for the rotation angle. The rotation of the first horizontal plate will drive the rotation of the driving wheel. Under the action of the transmission belt, the driven wheel and the balance plate at the output end of the continuously variable transmission will rotate. By analyzing the change value of the inclination of the balance plate through the inclination sensor, the flatness value of the foundation bed can be obtained.
[0022] Preferably, as the monitoring device for the construction of the wharf berth project of the present invention, a connection box is fixedly connected to one side of the measurement box. A central shaft is fixedly connected to the inner side of the connection box. A winding drum is rotatably connected to the outer side of the central shaft. A clockwork spring is arranged between the winding drum and the central shaft. The two ends of the clockwork spring are respectively fixedly connected to the inner side of the winding drum and the outer side of the central shaft. A pull rope is fixedly connected to the outer side of the winding drum. The pull rope is wound around the outer side of the winding drum. The other end of the pull rope passes through the connection box and is fixedly connected to the top end of the first horizontal plate. When the first horizontal plate is horizontal, the pull rope is completely wound around the outer side of the winding drum under the reset of the clockwork spring.
[0023] Preferably, as the monitoring device for the construction of the wharf berth project of the present invention, a toothed ring is fixedly connected to the outer side of one end of the winding drum. An electric push rod is fixedly connected to the top end of the connection box. A clamping block is fixedly connected to the movable end of the electric push rod. The clamping block can downwardly clamp the toothed ring. A limiting ring is fixedly connected to the inner side of one end of the connection box. The inner side of the limiting ring is slidably connected to the outer side of the movable end of the electric push rod.
[0024] Under the above settings, when the device descends to the foundation bed, the movable end of the electric push rod is at the lower side, the clamping block downwardly clamps the toothed ring, and the winding drum cannot rotate. The pull rope pulls the first horizontal plate and prevents the first horizontal plate from tilting downward. After the device descends to the foundation bed, the movable end of the electric push rod is at the upper side, the clamping block upwardly disengages from the toothed ring, and the winding drum can rotate. The pull rope is in a free state. At this time, the first horizontal plate can tilt up or down.
[0025] The monitoring method for the construction of the wharf berth project comprises the following steps:
[0026] Step 1: Move the monitoring device to the middle position of the foundation bed through an engineering ship, and then lower the monitoring device to the foundation bed through the traction mechanism on the engineering ship.
[0027] Step 2: Start monitoring. First, make the slider on the first cross plate move closer to the central column. After the slider on the first cross plate moves to the limit position of the stroke, make the slider on the second cross plate move closer to the central column. During the movement of the slider, the moving roller will continuously travel on the base bed, and the inclination angles of the first cross plate and the second cross plate will continuously change;
[0028] Step 3: Since the supporting plate is at the end position of the second cross plate, when the moving roller travels on the base bed, due to the longer force arm, the change in the perpendicularity of the base bed acting on the change in the inclination angle of the second cross plate will be less sensitive. During the movement of the supporting plate towards the central column, the stepless transmission is used to increase the speed, the force arm gradually shortens, and the transmission ratio of the stepless transmission gradually decreases. When the supporting plate reaches the midpoint of the first cross plate, the measurement ends. At this time, the transmission ratio of the stepless transmission reaches 1:1, which is used to play the role of rotational angle compensation;
[0029] Step 4: The rotation of the first cross plate will drive the rotation of the driving wheel. Under the action of the transmission belt, the driven wheel and the balance plate at the output end of the stepless transmission will rotate. By analyzing the change value of the inclination angle of the balance plate, the flatness value of the base bed can be obtained.
[0030] Compared with the prior art, the beneficial effects of the present invention are:
[0031] 1. For the monitoring device used in the construction of the wharf berth project, the present invention can directly compare multiple points on the base bed without the need for an extra reference plane for calibration, and can more effectively and directly obtain the flatness parameters of the base bed, and increase the accuracy of monitoring. The first cross plate in the present invention is symmetrically arranged, and the supporting plates and moving rollers on both sides move synchronously to cancel out the pulling forces on both sides and increase the stability during the monitoring process. The present invention directly converts the height change of the base bed into continuous inclination angle changes, and directly compares the corresponding inclination angle values at each base bed position, greatly increasing the accuracy during the monitoring process and avoiding the problem of uncontrollable reference planes. The moving roller in the present invention is internally provided with a counterweight block to increase the adhesion between the moving roller and the base bed.
[0032] 2. For the monitoring device used in the construction of the wharf berth project, the bottom ends of the support rods and the bottom ends of the movable ends of the hydraulic rods can be provided with spines to further increase the stability. The present invention mainly realizes the monitoring of flatness through the comparison of inclination angles. Even if the bottom plate undergoes a slight displacement, the interference with the result of the inclination angle comparison will not be large.
[0033] 3. For the monitoring device used in the construction of the wharf berth project, through the arranged driven block and potentiometer, etc., the positions of the driven block and the moving roller can be obtained, and the transmission ratio of the stepless transmission can be changed through this position, and it is used to judge the progress of the monitoring operation.
[0034] 4. When the monitoring device for wharf berth project construction is in use, the monitoring device is moved to the middle position of the bed by an engineering ship, and then the monitoring device is lowered onto the bed by the traction mechanism on the engineering ship. During monitoring, first, the slider on the first cross plate moves towards the central column. When the slider on the first cross plate moves to the limit position of the stroke, the slider on the second cross plate moves towards the central column. During the movement of the slider, the moving roller will continuously travel on the bed. The potentiometer set obtains the position of the moving roller in real time, and the inclination of the first cross plate and the second cross plate will continuously change.
[0035] 5. For the monitoring device for wharf berth project construction, when the support plate is at the end position of the second cross plate and the moving roller travels on the bed, due to the longer force arm, the change in the perpendicularity of the bed acting on the change in the inclination angle of the second cross plate will be less sensitive. During the movement of the support plate towards the central column, the stepless speed changer is used to increase the speed, the force arm gradually shortens, and the transmission ratio of the stepless speed changer gradually decreases. When the support plate reaches the midpoint of the first cross plate, the measurement ends. At this time, the transmission ratio of the stepless speed changer reaches 1:1, which is used to play a role in compensating the rotation angle. The rotation of the first cross plate will drive the driving wheel to rotate. Under the action of the transmission belt, the driven wheel and the balance plate at the output end of the stepless speed changer will rotate. The inclination change value of the balance plate is analyzed by the tilt sensor to obtain the flatness value of the bed.
[0036] 6. When the monitoring device for wharf berth project construction descends onto the bed, the movable end of the electric push rod is at the lower side, and the clamping block clamps the toothed ring downward, so that the drum cannot rotate, and the pull rope pulls the first cross plate and prevents the first cross plate from tilting downward. After the device descends onto the bed, the movable end of the electric push rod is at the upper side, the clamping block disengages from the toothed ring upward, the drum can rotate, and the pull rope is in a free state. At this time, the first cross plate can tilt up or down. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0048] Embodiment 1, please refer to Figures 1-5 and Figure 8 , the present invention provides a technical solution:
[0049] A monitoring device for wharf berth project construction, including a central column 3 and an engineering ship. Both sides of the central column 3 are rotatably connected to a first cross plate 13 through hinges. A second cross plate 14 is slidably connected to the first cross plate 13. The first cross plate 13 and the second cross plate 14 are parallel. Screws 15 are rotatably connected to the inner sides of the first cross plate 13 and the second cross plate 14. Sliders 16 are helically connected to the outer sides of the screws 15. Waterproof motors 17 are fixedly connected to the inner sides of the first cross plate 13 and the second cross plate 14. The output ends of the waterproof motors 17 are fixedly connected to the corresponding screws 15. The slider 16 in the first cross plate 13 is fixedly connected to one end of the second cross plate 14. The slider 16 in the second cross plate 14 is fixedly connected to a support plate 18. The bottom end of the support plate 18 is rotatably connected to a moving roller 19, and the moving roller 19 can slide on the bed 1;
[0050] During the process of the moving roller 19 sliding on the base bed 1, the inclination degrees of the first cross plate 13 and the second cross plate 14 will continuously change. By obtaining the change values of the inclination degrees of the first cross plate 13 and the second cross plate 14, the flatness value of the base bed 1 can be obtained.
[0051] Under the above settings, the present invention can directly compare multiple points on the base bed without the need for an extra reference plane for calibration, and can more effectively and directly obtain the flatness parameters of the base bed, and increase the accuracy of monitoring. The first cross plate 13 in the present invention is symmetrically arranged, and the supporting plates 18 and the moving rollers 19 on both sides move synchronously, in order to cancel out the pulling forces on both sides and increase the stability during the monitoring process;
[0052] The present invention directly converts the height change of the base bed 1 into continuous inclination degree changes, and directly compares the corresponding inclination degree values at each position of the base bed 1, greatly increasing the accuracy during the monitoring process and avoiding the problem of uncontrollable reference planes; The moving roller 19 in the present invention is internally provided with a counterweight block for increasing the adhesion between the moving roller 19 and the base bed 1;
[0053] Specifically, the bottom end of the central column 3 is fixedly connected with a bottom plate 10. The middle position at the bottom end of the bottom plate 10 is fixedly connected with a support rod 12. The outer edge at the bottom end of the bottom plate 10 is fixedly connected with a hydraulically actuated rod 11 arranged obliquely. The bottom plate 10 is supported by the bottom end of the support rod 12 and the movable end of the hydraulically actuated rod 11 abutting against the base bed 1.
[0054] Under the above settings, the bottom ends of the support rod 12 and the movable end of the hydraulically actuated rod 11 can be provided with spikes to further increase the stability. The present invention mainly monitors the flatness by comparing the inclination degrees. Even if the bottom plate 10 undergoes a slight displacement, the interference with the result of the inclination degree comparison will not be large;
[0055] Specifically, the top end of the central column 3 is fixedly connected with a water pump 4. The top end of the water pump 4 is fixedly connected with a drain pan 6. The water suction pipes 5 at the input end of the water pump 4 are arranged on the left and right sides of the water pump 4. When the water pump 4 works, water is pumped by the water suction pipes 5 on both sides and drained by the drain pan 6 at the top, providing a continuous downward pressure for the bottom plate 10 to increase the stability of the bottom plate 10.
[0056] Under the above settings, a water pump 4 is provided in the present invention. When the water pump 4 works, it can provide a continuous downward pressure for the bottom plate 10 to increase the stability of the bottom plate 10;
[0057] Specifically, a connecting rod 7 is fixedly connected to the center of the top end of the drain pan 6. The top end of the connecting rod 7 is fixedly connected with a connecting rope 2. By retracting and releasing the connecting rope 2, the recovery of the central column 3 is realized. The connecting rope 2 can be tied to a non-loaded electric wire for realizing power supply;
[0058] Specifically, sliding grooves are provided on the inner sides of the first horizontal plate 13 and the second horizontal plate 14. The sliding grooves are in a closed state. A driven block 27 is slidably connected to the inner side of the sliding groove. The driven block 27 is made of a magnetic material and forms a magnetic attraction structure with the slider 16. When the slider 16 moves, the driven block 27 will slide synchronously. A potentiometer 36 distributed horizontally is embedded in the inner side of the sliding groove. The driven block 27 slides on the potentiometer 36 to determine the positions of the driven block 27 and the moving roller 19.
[0059] Under the above settings, by providing the driven block 27 and the potentiometer 36, etc., the positions of the driven block 27 and the moving roller 19 can be obtained. The transmission ratio of the stepless transmission 28 is changed according to this position, and it is used to judge the progress of the monitoring operation.
[0060] Specifically, a driving wheel 22 is fixedly connected to the rotating shaft of the first horizontal plate 13. Measuring boxes 20 are fixedly connected to the outer sides of the left and right ends of the central column 3. A stepless transmission 28 is fixedly connected to the inner side of the measuring box 20. The input shaft of the stepless transmission 28 passes through the measuring box 20 and is fixedly connected to a driven wheel 21. The driven wheel 21 and the driving wheel 22 are driven by a transmission belt 23. The output shaft of the stepless transmission 28 is fixedly connected to a balance plate 31. An inclination sensor 30 is fixedly connected to the balance plate 31. The inclination changes of the first horizontal plate 13 and the second horizontal plate 14 during the sliding of the moving roller 19 on the base bed 1 are obtained through the inclination sensor 30.
[0061] Specifically, a storage 29 for storing the inclination data obtained by the inclination sensor 30 is fixedly connected to the top of the measuring box 20.
[0062] During use, the monitoring device is moved to the middle position of the base bed 1 by an engineering ship, and then the monitoring device is lowered onto the base bed 1 through a traction mechanism on the engineering ship. During monitoring, first, the slider 16 on the first horizontal plate 13 is moved closer to the central column 3. After the slider 16 on the first horizontal plate 13 moves to the extreme position of the stroke, the slider 16 on the second horizontal plate 14 is moved closer to the central column 3. During the movement of the slider 16, the moving roller 19 will continuously travel on the base bed 1. The potentiometer 36 provided obtains the position of the moving roller 19 in real time, and the inclination degrees of the first horizontal plate 13 and the second horizontal plate 14 will continuously change;
[0063] When the support plate 18 is at the end position of the second cross plate 14, when the moving roller 19 travels on the bed 1, due to the relatively long lever arm, the change in the perpendicularity of the bed 1 acting on the change in the inclination angle of the second cross plate 14 will be less sensitive. During the process of the support plate 18 moving towards the central column 3, the stepless speed variator 28 is used for speed increase, the lever arm gradually shortens, and the transmission ratio of the stepless speed variator 28 gradually decreases. When the support plate 18 reaches the midpoint of the first cross plate 13, the measurement ends. At this time, the transmission ratio of the stepless speed variator 28 reaches 1:1, which is used to play a role in compensating the rotation angle. The rotation of the first cross plate 13 will drive the driving wheel 22 to rotate. Under the action of the transmission belt 23, the driven wheel 21 and the balance plate 31 at the output end of the stepless speed variator 28 will rotate. By analyzing the change value of the inclination of the balance plate 31 through the inclination sensor 30, the flatness value of the bed 1 can be obtained.
[0064] Embodiment 2, this embodiment is a further improvement of Embodiment 1. Please refer to Figures 1-8 , one side of the measuring box 20 is fixedly connected with a connecting box 8. The inner side of the connecting box 8 is fixedly connected with a central shaft 25. The outer side of the central shaft 25 is rotationally connected with a winding drum 24. A hairspring 26 is arranged between the winding drum 24 and the central shaft 25. The two ends of the hairspring 26 are respectively fixedly connected with the inner side of the winding drum 24 and the outer side of the central shaft 25. The outer side of the winding drum 24 is fixedly connected with a pulling rope 9. The pulling rope 9 is wound around the outer side of the winding drum 24. The other end of the pulling rope 9 passes through the connecting box 8 and is fixedly connected with the top end of the first cross plate 13. When the first cross plate 13 is horizontal, the pulling rope 9 is completely wound around the outer side of the winding drum 24 under the reset of the hairspring 26.
[0065] Specifically, a toothed ring 32 is fixedly connected to the outer side of one end of the winding drum 24. The top end of the connecting box 8 is fixedly connected with an electric push rod 33. The movable end of the electric push rod 33 is fixedly connected with a clamping block 35. The clamping block 35 can downwardly clamp the toothed ring 32. One end of the inner side of the connecting box 8 is fixedly connected with a limiting ring 34. The inner side of the limiting ring 34 is slidably connected with the outer side of the movable end of the electric push rod 33.
[0066] Under the above settings, when the device descends onto the bed 1, the movable end of the electric push rod 33 is at the lower side, the clamping block 35 downwardly clamps the toothed ring 32, and the winding drum 24 cannot rotate. The pulling rope 9 pulls the first cross plate 13 and prevents the first cross plate 13 from tilting downward. After the device descends onto the bed 1, the movable end of the electric push rod 33 is at the upper side, the clamping block 35 upwardly disengages from the toothed ring 32, the winding drum 24 can rotate, and the pulling rope 9 is in a free state. At this time, the first cross plate 13 can tilt up or down.
[0067] The present invention also discloses a monitoring method for the construction of a wharf berth project, and its steps are as follows:
[0068] Step 1: Move the monitoring device to the middle position of the foundation bed 1 by an engineering ship, and then lower the monitoring device onto the foundation bed 1 through the traction mechanism on the engineering ship;
[0069] Step 2: Start monitoring. First, make the slider 16 on the first cross plate 13 move towards the central column 3. When the slider 16 on the first cross plate 13 moves to the limit position of the stroke, make the slider 16 on the second cross plate 14 move towards the central column 3. During the movement of the slider 16, the moving roller 19 will continuously travel on the foundation bed 1, and the inclination angles of the first cross plate 13 and the second cross plate 14 will continuously change;
[0070] Step 3: Since when the support plate 18 is at the end position of the second cross plate 14, when the moving roller 19 travels on the foundation bed 1, due to the longer force arm, the change in the perpendicularity of the foundation bed 1 acting on the change in the inclination angle of the second cross plate 14 will be less sensitive. During the movement of the support plate 18 towards the central column 3, the stepless speed variator 28 is used for speed increase, the force arm gradually shortens, and the transmission ratio of the stepless speed variator 28 gradually decreases. When the support plate 18 reaches the midpoint of the first cross plate 13, the measurement ends. At this time, the transmission ratio of the stepless speed variator 28 reaches 1:1, which is used to play a role in compensating the rotation angle;
[0071] Step 4: The rotation of the first cross plate 13 will drive the rotation of the driving wheel 22. Under the action of the transmission belt 23, the driven wheel 21 and the balance plate 31 at the output end of the stepless speed variator 28 will rotate. By analyzing the change value of the inclination angle of the balance plate 31, the flatness value of the foundation bed 1 can be obtained.
[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
