Description

Technical Field

[0001] The present invention relates to the technical field of berth construction base bed flatness monitoring, and in particular to a monitoring device and method for dock berth engineering construction. Background Art

[0002] After blasting, the underwater block bed needs to be supplemented with materials, re-rammed and leveled to meet the requirements for caisson installation. The acceptance of its leveling is of great significance to ensuring the quality of the project. The allowable deviation value of the bed leveling is ±50mm. However, due to the particularity of the underwater environment, traditional bed leveling acceptance devices often have problems such as insufficient accuracy and complex operation, which can hardly meet the needs of modern wharf projects.

[0003] In the prior art, a stable reference surface is required for deviation measurement. The deviation is obtained by measuring multiple points on the base bed and comparing them with the reference surface. For example, an engineering ship is used as a reference surface for operation and comparison. However, an engineering ship at sea level is not a good reference surface and is greatly affected by tides and wind interference.

[0004] The present invention provides a monitoring device for the flatness of the base bed, which can directly compare multiple points on the base bed without the need for an extra reference surface for calibration, and can more effectively and directly obtain the flatness parameters of the base bed.

[0005] Therefore, in order to solve the above problems, a monitoring device and method for the construction of a dock berth project are proposed. Summary of the invention

[0006] The object of the present invention is to provide a monitoring device and method for the construction of a dock berth project, which can directly compare multiple points on the base bed without the need for an extra reference surface for calibration, and can more effectively and directly obtain the flatness parameters of the base bed.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a monitoring device for the construction of a dock berth project, comprising a central column and an engineering vessel, both sides of the central column are rotatably connected to a first transverse plate through a hinge, the first transverse plate is slidably connected to a second transverse plate, the first transverse plate and the second transverse plate are parallel, the inner sides of the first transverse plate and the second transverse plate are rotatably connected to a screw rod, the outer sides of the screw rod are spirally connected to a slider, the inner sides of the first transverse plate and the second transverse plate are fixedly connected to a waterproof motor, the output end of the waterproof motor is fixedly connected to the corresponding screw rod, the slider in the first transverse plate is fixedly connected to one end of the second transverse plate, the slider in the second transverse plate is fixedly connected to a support plate, the bottom end of the support plate is rotatably connected to a moving roller, and the moving roller can slide on the base bed;

[0008] When the movable roller slides on the base bed, the inclinations of the first transverse plate and the second transverse plate will continuously change. The flatness value of the base bed can be obtained by obtaining the inclination change values ​​of the first transverse plate and the second transverse plate.

[0009] Under the above settings, the present invention can directly compare multiple points on the base bed without the need for an extra reference surface for calibration, and can more effectively and directly obtain the flatness parameters of the base bed, and increase the accuracy of monitoring. The first horizontal plate in the present invention is symmetrically arranged, and the support plates and moving rollers on both sides thereof move synchronously, so as to offset the pulling forces on the left and right sides, thereby increasing the stability during the monitoring process;

[0010] The present invention directly converts the height change of the base bed into a continuous inclination change, and directly compares the corresponding inclination values ​​at each base bed position, which greatly increases the accuracy of the monitoring process and avoids the problem of uncontrollable reference surface. The movable roller in the present invention has a built-in counterweight block to increase the fit between the movable roller and the base bed.

[0012] Under the above setting, the bottom end of the support rod and the bottom end of the movable end of the hydraulic rod can be set in a spike shape to further increase stability. The present invention mainly realizes the flatness monitoring through the comparison of the inclination. Even if the bottom plate is slightly displaced, the interference to the result of the inclination comparison will not be great.

[0013] As a preferred monitoring device for the construction of dock berth projects of the present invention, a water pump is fixedly connected to the top of the central column, a drain pan is fixedly connected to the top of the water pump, and a suction pipe at the input end of the water pump is arranged on the left and right sides of the water pump. When the water pump is working, water is pumped by the suction pipes on both sides and drained by the drain pan at the top, thereby providing continuous downward pressure for the bottom plate to increase the stability of the bottom plate.

[0014] Under the above configuration, a water pump is provided in the present invention, and when the water pump is working, it can provide continuous downward pressure to the bottom plate to increase the stability of the bottom plate;

[0015] As a preferred monitoring device for the construction of dock berth engineering of the present invention, a connecting rod is fixedly connected to the top center of the drain pan, and a connecting rope is fixedly connected to the top of the connecting rod. The central column can be recovered by retracting and releasing the connecting rope. The connecting rope can be bound to an unstressed wire to realize power supply;

[0016] As a preferred monitoring device for the construction of dock berth projects of the present invention, the inner sides of the first and second transverse plates are provided with slide grooves, the slide grooves are in a closed state, the inner sides of the slide grooves are slidably connected with driven blocks, the driven blocks are made of magnetic material, and form a magnetic attraction structure with the slider, when the slider moves, the driven blocks will slide synchronously, and laterally distributed potentiometers are embedded in the inner sides of the slide grooves, the driven blocks slide on the potentiometers, so as to judge the positions of the driven blocks and the moving rollers.

[0017] Under the above settings, the positions of the driven block and the moving roller can be obtained through the set driven block and potentiometer, etc., and the transmission ratio of the continuously variable transmission is changed according to the position, and is used to judge the progress of the monitoring operation.

[0018] As a preferred monitoring device for the construction of dock berth projects of the present invention, a driving wheel is fixedly connected to the rotating shaft of the first transverse plate, a measuring box is fixedly connected to the outer sides of the left and right ends of the central column, a continuously variable transmission is fixedly connected to the inner side of the measuring box, the input shaft of the continuously variable transmission passes through the measuring box and is fixedly connected to a driven wheel, transmission is achieved between the driven wheel and the driving wheel through a transmission belt, the output shaft of the continuously variable transmission is fixedly connected to a balance plate, and a tilt sensor is fixedly connected to the balance plate, and the tilt change of the first and second transverse plates during the sliding of the moving roller on the base bed is obtained through the tilt sensor.

[0019] As a preferred embodiment of the monitoring device for the construction of a dock berth project of the present invention, a storage device for storing the tilt data obtained by the tilt sensor is fixedly connected to the top of the measuring box.

[0020] When in use, the monitoring device is moved to the middle position of the base bed by the engineering vessel, and then the monitoring device is lowered to the base bed by the traction mechanism on the engineering vessel. When monitoring, the slider on the first horizontal plate is first moved closer to the center column. When the slider on the first horizontal plate moves to the limit position of the stroke, the slider on the second horizontal plate is moved closer to the center column. During the movement of the slider, the moving roller will continuously move on the base bed, and the set potentiometer will obtain the position of the moving roller in real time, and the inclination of the first horizontal plate and the second horizontal plate will continuously change.

[0021] Because when the support plate is at the end position of the second horizontal plate, when the moving roller walks on the base bed, due to the long force arm, the vertical change of the base bed will not be sensitive enough to the change of the inclination angle of the second horizontal plate. In the process of the support plate moving toward the center column, the continuously variable transmission is used to increase the speed, the force arm is gradually shortened, and the transmission ratio of the continuously variable transmission is gradually reduced. When the support plate reaches one-half of the first horizontal plate, the measurement is completed. At this time, the transmission ratio of the continuously variable transmission reaches 1:1, which is used to compensate for the rotation angle. The rotation of the first horizontal 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 continuously variable transmission will rotate. The inclination change value of the balance plate is analyzed by the tilt sensor to obtain the flatness value of the base bed.

[0022] As a preferred monitoring device for the construction of dock berth projects of the present invention, one side of the measuring box is fixedly connected to a connecting box, the inner side of the connecting box is fixedly connected to a central axis, the outer side of the central axis is rotatably connected to a reel, a spring is arranged between the reel and the central axis, the two ends of the spring are respectively fixedly connected to the inner side of the reel and the outer side of the central axis, the outer side of the reel is fixedly connected to a pull rope, the pull rope is wound around the outer side of the reel, the other end of the pull rope passes through the connecting box and is fixedly connected to the top end of the first horizontal plate, and when the first horizontal plate is horizontal, the pull rope is completely wound around the outer side of the reel under the resetting of the spring.

[0023] As a preferred monitoring device for the construction of dock berth projects of the present invention, a gear ring is fixedly connected to the outer side of one end of the reel, an electric push rod is fixedly connected to the top of the connecting box, a clamping block is fixedly connected to the movable end of the electric push rod, and the clamping block can clamp the gear ring downward, and a limiting ring is fixedly connected to the inner side of one end of the connecting box, and 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 base bed, the movable end of the electric push rod is on the lower side, the block clamps the gear ring downward, 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 to the base bed, the movable end of the electric push rod is on the upper side, the block disengages from the gear ring upward, the drum can rotate, and the pull rope is in a free state. At this time, the first cross plate can be tilted up or down.

[0025] The monitoring method for the construction of a wharf berth project comprises the following steps:

[0026] Step 1: The monitoring device is moved to the middle position of the bed by the engineering vessel, and then the monitoring device is lowered to the bed by the traction mechanism on the engineering vessel;

[0027] Step 2: Start monitoring. First, move the slider on the first horizontal plate closer to the center column. When the slider on the first horizontal plate moves to the limit position of the stroke, move the slider on the second horizontal plate closer to the center column. During the movement of the slider, the moving roller will continuously move on the base bed, and the inclination of the first horizontal plate and the second horizontal plate will continuously change.

[0028] Step 3: When the support plate is at the end of the second horizontal plate, when the moving roller walks on the base bed, the vertical change of the base bed will not be sensitive enough to the change of the inclination angle of the second horizontal plate due to the long force arm. In the process of the support plate moving toward the center column, the continuously variable transmission is used to increase the speed, the force arm is gradually shortened, and the transmission ratio of the continuously variable transmission is gradually reduced. When the support plate reaches half 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 the role of rotation angle compensation;

[0029] Step 4: The rotation of the first horizontal 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 continuously variable transmission will rotate. The flatness value of the base bed can be obtained by analyzing the change in the inclination of the balance plate.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The monitoring device used for the construction of dock berth projects can directly compare multiple points on the base bed without the need for an extra reference surface 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 support plates and movable rollers on both sides thereof move synchronously, so as to offset the pulling forces on the left and right sides and increase the stability during the monitoring process. The present invention directly converts the height change of the base bed into a continuous inclination change, and directly compares the corresponding inclination values ​​at each base bed position, which greatly increases the accuracy during the monitoring process and avoids the problem of uncontrollable reference surfaces. The movable roller in the present invention has a built-in counterweight block to increase the fit between the movable roller and the base bed.

[0032] 2. The monitoring device used for the construction of dock berth projects can be provided with spikes at the bottom end of the support rod and the bottom end of the movable end of the hydraulic rod to further increase stability. The present invention mainly realizes the flatness monitoring by comparing the inclination. Even if the bottom plate is slightly displaced, it will not greatly interfere with the result of the inclination comparison.

The monitoring device used for the construction of the wharf berth project can obtain the position of the driven block and the moving roller through the set driven block and potentiometer, etc., and change the transmission ratio of the continuously variable transmission through the position, and is used to judge the progress of the monitoring operation.

[0034] 4. When the monitoring device for the construction of the wharf berth project is used, the monitoring device is moved to the middle position of the base bed by the engineering vessel, and then the monitoring device is lowered to the base bed by the traction mechanism on the engineering vessel. During monitoring, the slider on the first horizontal plate is first moved closer to the center column. When the slider on the first horizontal plate moves to the limit position of the stroke, the slider on the second horizontal plate is moved closer to the center column. During the movement of the slider, the moving roller will continuously move on the base bed, and the set potentiometer will obtain the position of the moving roller in real time, and the inclination of the first horizontal plate and the second horizontal plate will continuously change.

[0035] 5. The monitoring device used for the construction of dock berth projects, because when the support plate is at the end position of the second horizontal plate, when the moving roller walks on the base bed, due to the long force arm, the vertical change of the base bed will not be sensitive enough to the change of the inclination angle of the second horizontal plate. In the process of the support plate moving toward the center column, the continuously variable transmission is used to increase the speed, the force arm is gradually shortened, and the transmission ratio of the continuously variable transmission is gradually reduced. When the support plate reaches the half of the first horizontal plate, the measurement is completed. At this time, the transmission ratio of the continuously variable transmission reaches 1:1, which is used to play a role in rotation angle compensation. The rotation of the first horizontal 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 continuously variable transmission will rotate. The inclination change value of the balance plate is analyzed by the tilt sensor to obtain the flatness value of the base bed.

The monitoring device used for the construction of dock berth projects, when the device is lowered to the base bed, the movable end of the electric push rod is on the lower side, the block clamps the gear ring downward, 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 is lowered to the base bed, the movable end of the electric push rod is on the upper side, the block disengages from the gear ring upward, the drum can rotate, and the pull rope is in a free state. At this time, the first cross plate can be tilted up or down. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1, please refer to Figure 1-Figure 5 and Figure 8 , the present invention provides a technical solution:

[0049] A monitoring device for the construction of a wharf berth project, comprising a central column 3 and an engineering vessel, wherein both sides of the central column 3 are rotatably connected with a first transverse plate 13 through a hinge, a second transverse plate 14 is slidably connected to the first transverse plate 13, the first transverse plate 13 and the second transverse plate 14 are parallel, the inner sides of the first transverse plate 13 and the second transverse plate 14 are rotatably connected with a screw rod 15, the outer side of the screw rod 15 is spirally connected with a slider 16, the inner sides of the first transverse plate 13 and the second transverse plate 14 are fixedly connected with a waterproof motor 17, the output end of the waterproof motor 17 is fixedly connected with the corresponding screw rod 15, the slider 16 in the first transverse plate 13 is fixedly connected with one end of the second transverse plate 14, the slider 16 in the second transverse plate 14 is fixedly connected with a support plate 18, the bottom end of the support plate 18 is rotatably connected with a moving roller 19, and the moving roller 19 can slide on the base bed 1;

[0050] When the movable roller 19 slides on the base bed 1 , the inclinations of the first transverse plate 13 and the second transverse plate 14 will continuously change. By obtaining the inclination change values ​​of the first transverse plate 13 and the second transverse 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 surface 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 support plates 18 and the moving rollers 19 on both sides thereof move synchronously, so as to offset the pulling forces on the left and right sides, thereby increasing the stability during the monitoring process;

[0052] The present invention directly converts the height change of the base bed 1 into a continuous inclination change, and directly compares the corresponding inclination values ​​at each position of the base bed 1, which greatly increases the accuracy of the monitoring process and avoids the problem of uncontrollable reference surface; the movable roller 19 of the present invention has a built-in counterweight block to increase the fit between the movable roller 19 and the base bed 1;

[0053] Specifically, the bottom end of the central column 3 is fixedly connected to the base plate 10, the middle position of the bottom end of the base plate 10 is fixedly connected to the support rod 12, the outer edge of the bottom end of the base plate 10 is fixedly connected to the inclined hydraulic rod 11, and the support of the base plate 10 is achieved by the bottom end of the support rod 12 and the movable end of the hydraulic rod 11 contacting the base bed 1.

[0054] Under the above setting, the bottom end of the support rod 12 and the bottom end of the movable end of the hydraulic rod 11 can be set in a spike shape to further increase stability. The present invention mainly realizes the flatness monitoring by comparing the inclination. Even if the bottom plate 10 is slightly displaced, the interference to the result of the inclination comparison will not be great.

[0055] Specifically, a water pump 4 is fixedly connected to the top of the central column 3, a drain pan 6 is fixedly connected to the top of the water pump 4, and a pumping pipe 5 at the input end of the water pump 4 is arranged on the left and right sides of the water pump 4. When the water pump 4 is working, water is pumped by the pumping pipes 5 on both sides and drained by the drain pan 6 at the top, providing continuous downward pressure for the base plate 10 to increase the stability of the base plate 10.

[0056] Under the above configuration, the present invention is provided with a water pump 4, which, when working, can provide a continuous downward pressure to 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 of the drain pan 6, and a connecting rope 2 is fixedly connected to the top of the connecting rod 7. By retracting and releasing the connecting rope 2, the central column 3 can be recovered. The connecting rope 2 can be used to bind unstressed wires to achieve power supply;

[0058] Specifically, a slide groove is provided on the inner side of the first transverse plate 13 and the second transverse plate 14, and the slide groove is in a closed state. A follower block 27 is slidably connected to the inner side of the slide groove. The follower block 27 is made of a magnetic material and forms a magnetic attraction structure with the slider 16. When the slider 16 moves, the follower block 27 will slide synchronously. A laterally distributed potentiometer 36 is embedded on the inner side of the slide groove, and the follower block 27 slides on the potentiometer 36, so as to determine the position of the follower block 27 and the movable roller 19.

[0059] Under the above settings, the positions of the driven block 27 and the moving roller 19 can be obtained by setting the driven block 27 and the potentiometer 36, etc., and the transmission ratio of the continuously variable transmission 28 is changed by the position, and 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 transverse plate 13, a measuring box 20 is fixedly connected to the outer sides of the left and right ends of the center column 3, a continuously variable transmission 28 is fixedly connected to the inner side of the measuring box 20, an input shaft of the continuously variable transmission 28 passes through the measuring box 20 and is fixedly connected to a driven wheel 21, transmission is achieved between the driven wheel 21 and the driving wheel 22 via a transmission belt 23, a balance plate 31 is fixedly connected to the output shaft of the continuously variable transmission 28, a tilt sensor 30 is fixedly connected to the balance plate 31, and the tilt change of the first transverse plate 13 and the second transverse plate 14 during the sliding of the moving roller 19 on the base bed 1 is obtained through the tilt sensor 30.

[0061] Specifically, a storage device 29 for storing the tilt data obtained by the tilt sensor 30 is fixedly connected to the top of the measuring box 20 .

[0062] When in use, the monitoring device is moved to the middle position of the base bed 1 by the engineering vessel, and then the monitoring device is lowered onto the base bed 1 by the traction mechanism on the engineering vessel. When monitoring, the slider 16 on the first transverse plate 13 is first moved closer to the center column 3. When the slider 16 on the first transverse plate 13 moves to the limit position of the stroke, the slider 16 on the second transverse plate 14 is moved closer to the center column 3. During the movement of the slider 16, the moving roller 19 will continuously move on the base bed 1, and the set potentiometer 36 will obtain the position of the moving roller 19 in real time, and the inclination of the first transverse plate 13 and the second transverse plate 14 will continuously change.

[0063] Because when the support plate 18 is at the end position of the second cross plate 14, when the moving roller 19 walks on the base bed 1, due to the long force arm, the vertical change of the base bed 1 will not be sensitive enough to the change in the inclination angle of the second cross plate 14. In the process of the support plate 18 moving toward the center column 3, the continuously variable transmission 28 is used to increase the speed, the force arm is gradually shortened, and the transmission ratio of the continuously variable transmission 28 is gradually reduced. When the support plate 18 reaches one-half of the first cross plate 13, the measurement is completed. At this time, the transmission ratio of the continuously variable transmission 28 reaches 1:1, which is used to play a role in rotation angle compensation. 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 continuously variable transmission 28 will rotate. The inclination change value of the balance plate 31 is analyzed by the inclination sensor 30 to obtain the flatness value of the base bed 1.

[0064] Example 2: This example is a further improvement of Example 1. Figure 1-Figure 8 A connecting box 8 is fixedly connected to one side of the measuring box 20, a central axis 25 is fixedly connected to the inner side of the connecting box 8, a reel 24 is rotatably connected to the outer side of the central axis 25, a spring 26 is arranged between the reel 24 and the central axis 25, two ends of the spring 26 are respectively fixedly connected to the inner side of the reel 24 and the outer side of the central axis 25, a pull rope 9 is fixedly connected to the outer side of the reel 24, the pull rope 9 is wound around the outer side of the reel 24, the other end of the pull rope 9 passes through the connecting box 8 and is fixedly connected to the top end of the first horizontal plate 13, when the first horizontal plate 13 is horizontal, the pull rope 9 is completely wound around the outer side of the reel 24 under the resetting of the spring 26.

[0065] Specifically, a gear ring 32 is fixedly connected to the outer side of one end of the reel 24, an electric push rod 33 is fixedly connected to the top of the connecting box 8, a clamping block 35 is fixedly connected to the movable end of the electric push rod 33, and the clamping block 35 can clamp the gear ring 32 downward, and a limiting ring 34 is fixedly connected to the inner side of one end of the connecting box 8, and the inner side of the limiting ring 34 is slidably connected to the outer side of the movable end of the electric push rod 33.

[0066] Under the above setting, when the device descends onto the base bed 1, the movable end of the electric push rod 33 is on the lower side, the block 35 clamps the gear ring 32 downward, the drum 24 cannot rotate, and the pull rope 9 pulls the first cross plate 13 and prevents the first cross plate 13 from tilting downward. After the device descends onto the base bed 1, the movable end of the electric push rod 33 is on the upper side, the block 35 disengages from the gear ring 32 upward, the drum 24 can rotate, and the pull rope 9 is in a free state. At this time, the first cross plate 13 can be tilted up or down.

[0067] The present invention also discloses a monitoring method for the construction of a dock berth project, the steps of which are:

[0068] Step 1: The monitoring device is moved to the middle position of the bed 1 by the engineering vessel, and then the monitoring device is lowered onto the bed 1 by the traction mechanism on the engineering vessel;

[0069] Step 2: Start monitoring. First, make the slider 16 on the first transverse plate 13 move closer to the center column 3. When the slider 16 on the first transverse plate 13 moves to the limit position of the stroke, make the slider 16 on the second transverse plate 14 move closer to the center column 3. During the movement of the slider 16, the moving roller 19 will continuously move on the base bed 1, and the inclination of the first transverse plate 13 and the second transverse plate 14 will continuously change.

[0070] Step 3: Because the support plate 18 is at the end position of the second horizontal plate 14, when the moving roller 19 walks on the base bed 1, due to the long lever arm, the vertical change of the base bed 1 will not be sensitive enough to the change of the inclination angle of the second horizontal plate 14. In the process of the support plate 18 moving toward the central column 3, the continuously variable transmission 28 is used to increase the speed, the lever arm is gradually shortened, and the transmission ratio of the continuously variable transmission 28 is gradually reduced. When the support plate 18 reaches one-half of the first horizontal plate 13, the measurement is completed. At this time, the transmission ratio of the continuously variable transmission 28 reaches 1:1, which is used to play a role in rotation angle compensation;

A monitoring method for the construction of a dock berth project, characterized in that: The monitoring device for the construction of a dock berth project as claimed in claim 9 comprises the following steps: Step 1: The monitoring device is moved to the middle position of the bed (1) by means of an engineering vessel, and then the monitoring device is lowered onto the bed (1) by means of a traction mechanism on the engineering vessel; Step 2: Start monitoring, first make the slider (16) on the first transverse plate (13) move closer to the center column (3), when the slider (16) on the first transverse plate (13) moves to the limit position of the stroke, make the slider (16) on the second transverse plate (14) move closer to the center column (3), during the movement of the slider (16), the moving roller (19) will continuously move on the base bed (1), and the inclination of the first transverse plate (13) and the second transverse plate (14) will continuously change; Step 3: Because the support plate (18) is at the end position of the second horizontal plate (14), when the moving roller (19) walks on the base bed (1), due to the long force arm, the vertical change of the base bed (1) will not be sensitive enough to the change of the inclination angle of the second horizontal plate (14).

By analyzing the change in the inclination of the balance plate (31), the flatness value of the base bed (1) is obtained.
