During the construction of bridges, it is necessary to measure the height of each bridge body. The height data of the bridge body is directly related to the construction status and quality of the entire bridge. Therefore, the corresponding measuring devices used to measure the height have also received corresponding attention.

[0008] Furthermore, the winding mechanism includes a winding shaft, the reflective cloth strip is wound around the outer edge of the winding shaft, vertical plates are provided at the front and rear ends of the winding shaft, the two ends of the winding shaft pass through adjacent vertical plates, the vertical plates are fixedly connected to the top of the bottom plate, the vertical plates and the winding shaft are rotatably connected, a planar spiral spring is fixedly connected to the outer edge of the winding shaft near the front end, a fixing plate is fixedly connected to the end of the planar spiral spring away from the winding shaft, and the fixing plate is fixedly connected to the adjacent vertical plate.

[0009] Furthermore, a sealing ring is provided between the annular floating plate and the threaded tube, and the outer diameter of the annular floating plate is larger than the inner diameter of the circular hole.

[0010] Furthermore, the threaded tube and the threaded column are threadedly connected, and a plurality of anti-slip strips are fixedly connected to the outer edge of the threaded tube.

[0011] Furthermore, both ends of the first round rod penetrate the adjacent support plates, and the first round rod and the support plates are rotatably connected.

[0012] Furthermore, a pin is provided through the inner cavity of the roller, the pin is rotatably connected to the roller, and both ends of the pin are fixedly passed through the mounting frame.

[0014] Furthermore, the arc plate is fixedly connected to the top of the water tank, and a baffle is fixedly connected to the top of the arc plate.

[0015] A method for a bridge engineering height measuring device with a warning function, comprising the following steps:

[0016] Step 1: First, control the electric telescopic rod to shorten. The electric telescopic rod drives the mounting plate to move downward through the connecting plate. The mounting plate drives the universal wheel to move downward. At the same time, the plane scroll spring is wound. When the plane scroll spring is wound, it drives the winding shaft to rotate. The winding shaft winds up the reflective cloth strip until the universal wheel moves to fit the ground and lifts the bottom plate away from the ground. Then, the electric telescopic rod can stop working.

[0017] Step 2: Then move the bottom plate, which drives the universal wheels to roll on the ground, so that the device moves to the measuring position. After the device moves to a suitable position, water is poured into the water tank until the water level is flush with the bottom of the water tank;

[0018] Step 3: Then control the electric telescopic rod to extend, the electric telescopic rod drives the mounting plate and the universal wheel to move, the universal wheel moves away from the ground, so that the bottom plate fits the ground, thereby fixing the device to prevent the device from shifting during measurement, the mounting plate moves to pull the reflective cloth strip, and the reflective cloth strip is unfolded. When the reflective cloth strip is unfolded, the winding shaft is driven to rotate, and the winding shaft squeezes the plane scroll spring. When the electric telescopic rod drives the water tank and the distance sensor to move upward to the measuring position, the electric telescopic rod stops working. At this time, the reflective cloth strip is unfolded to play a reflective warning role;

[0019] Step 4: The water inside the water tank can adjust the horizontal state of the distance measuring sensor. When the ground where the bottom plate is located is not in a horizontal state, the water inside the water tank drives the annular floating plate to float, so that the annular floating plate is in a horizontal state. When the annular floating plate swings to the left or right due to the floating of the water surface, the annular floating plate drives the threaded column to swing, and the threaded column swings around the second round rod. The slot setting allows space for the first round rod when the threaded column swings. When the annular floating plate swings forward or backward due to the floating of the water surface, the annular floating plate drives the second round rod to swing through the threaded column, and the second round rod drives the roller to roll in the inner cavity of the limit groove, so as to adjust the horizontal state of the distance measuring sensor.

[0020] Step 5: Then adjust the distance measuring sensor to send a signal, and the signal receiving end receives the signal to obtain the measured height;

[0021] Step 6: After the measurement work is completed, control the electric telescopic rod to shorten, wind the reflective cloth strip around the shaft, until the universal wheel moves to fit the ground, and lift the bottom plate away from the ground, then rotate and hold the anti-slip strip on the threaded tube, rotate the threaded tube, and the threaded tube rotates on the outer edge of the threaded column. The threaded tube moves upward under the action of the thread of the threaded tube, and the threaded tube drives the annular floating plate to move upward. The annular floating plate moves upward to fit the top of the inner cavity of the water tank, and the annular floating plate blocks the circular hole to prevent water from spilling out of the water tank when the device is transferred. At the same time, it also prevents the ranging sensor from swinging and being hit during the transfer process, thereby protecting the ranging sensor.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention provides a height measuring device and method for bridge engineering with a warning function. When the electric telescopic rod is working, the universal wheel can be moved away from the ground to fix the device, and the reflective cloth strip can be unfolded to play a reflective warning role. At the same time, the height of the distance measuring sensor can be adjusted, achieving three goals at one stroke, and the operation is more convenient;

[0024] 2. The present invention provides a height measurement device and method for bridge engineering with a warning function. The water content inside the water tank can adjust the horizontal state of the distance measuring sensor. When the ground where the bottom plate is located is not in a horizontal state, the water content inside the water tank drives the annular floating plate to float, so that the annular floating plate is in a horizontal state. When the annular floating plate swings to the left or right due to the floating of the water surface, the annular floating plate drives the threaded column to swing. The threaded column swings around the second round rod. The slotted arrangement allows space for the first round rod when the threaded column swings. When the annular floating plate swings forward or backward due to the floating of the water surface, the annular floating plate drives the second round rod to swing through the threaded column. The second round rod drives the roller to roll in the inner cavity of the limit groove, thereby adjusting the horizontal state of the distance measuring sensor.

[0025] 3. The present invention provides a height measuring device and method for bridge engineering with a warning function. The anti-slip strip on the threaded tube is rotated and held, and the threaded tube is rotated. The threaded tube rotates on the outer edge of the threaded column, and moves upward under the action of the thread of the threaded tube. The threaded tube drives the annular floating plate to move upward, and the annular floating plate moves upward until it fits with the top of the inner cavity of the water tank. The annular floating plate blocks the circular hole to prevent water from spilling out of the water tank when the device is transferred. At the same time, it also prevents the ranging sensor from swinging and being hit during the transfer process, thereby protecting the ranging sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A method for a bridge engineering height measuring device with a warning function, comprising the following steps:

[0044] Step 1: First, the electric telescopic rod 2 is controlled to shorten, and the electric telescopic rod 2 drives the mounting plate 4 to move downward through the connecting plate 3, and the mounting plate 4 drives the universal wheel 5 to move downward, and at the same time, the plane scroll spring 9 is wound, and the plane scroll spring 9 drives the winding shaft 7 to rotate when winding, and the winding shaft 7 winds the reflective cloth strip 6 until the universal wheel 5 moves to fit the ground and lifts the bottom plate 1 away from the ground, and then the electric telescopic rod 2 stops working;

[0045] Step 2: Then move the bottom plate 1, and the bottom plate 1 drives the universal wheel 5 to roll on the ground, so that the device moves to the measuring position. After the device moves to a suitable position, water is poured into the water tank 11, and the water level is flush with the bottom of the water tank 11;

[0046] Step 3: Then control the electric telescopic rod 2 to extend, the electric telescopic rod 2 drives the mounting plate 4 and the universal wheel 5 to move, the universal wheel 5 moves away from the ground, so that the bottom plate 1 fits with the ground, thereby fixing the device to prevent the device from shifting during measurement, the mounting plate 4 moves to pull the reflective cloth strip 6, and the reflective cloth strip 6 is unfolded. When the reflective cloth strip 6 is unfolded, it drives the winding shaft 7 to rotate, and the winding shaft 7 squeezes the plane scroll spring 9. When the electric telescopic rod 2 drives the water tank 11 and the distance sensor 28 to move upward to the measuring position, the electric telescopic rod 2 stops working. At this time, the reflective cloth strip 6 is unfolded to play a reflective warning role;

[0047] Step 4: The water inside the water tank 11 can adjust the horizontal state of the distance measuring sensor 28. When the ground where the bottom plate 1 is located is not in a horizontal state, the water inside the water tank 11 drives the annular floating plate 13 to float, so that the annular floating plate 13 is in a horizontal state. When the annular floating plate 13 swings to the left or right due to the floating of the water surface, the annular floating plate 13 drives the threaded column 17 to swing. The threaded column 17 swings around the second round rod 21. The setting of the slot 18 allows space for the first round rod 19 when the threaded column 17 swings. When the annular floating plate 13 swings forward or backward due to the floating of the water surface, the annular floating plate 13 drives the second round rod 21 to swing through the threaded column 17. The second round rod 21 drives the roller 23 to roll in the inner cavity of the limit groove 26, so as to adjust the horizontal state of the distance measuring sensor 28.

[0048] Step 5: Then adjust the distance measuring sensor 28 to send a signal, and the signal receiving end receives the signal to obtain the measured height;

[0049] Step 6: After the measurement work is completed, the electric telescopic rod 2 is controlled to shorten, and the winding shaft 7 is used to reel in the reflective cloth strip 6 until the universal wheel 5 moves to fit the ground, and the bottom plate 1 is lifted up to away from the ground, and then the anti-slip strip 16 on the threaded tube 15 is rotated to hold the threaded tube 15, and the threaded tube 15 is rotated. The threaded tube 15 rotates on the outer edge of the threaded column 17, and moves upward under the action of the thread of the threaded tube 15. The threaded tube 15 drives the annular floating plate 13 to move upward, and the annular floating plate 13 moves upward to fit the top of the inner cavity of the water tank 11. The annular floating plate 13 blocks the circular hole 12 to prevent water from spilling out of the water tank 11 when the device is transferred, and also prevents the ranging sensor 28 from swinging and being hit during the transfer process, thereby protecting the ranging sensor 28.

[0050] Working principle: First, the electric telescopic rod 2 is controlled to shorten, and the electric telescopic rod 2 drives the mounting plate 4 to move downward through the connecting plate 3, and the mounting plate 4 drives the universal wheel 5 to move downward, and at the same time, the plane scroll spring 9 is wound, and the plane scroll spring 9 drives the winding shaft 7 to rotate when winding, and the winding shaft 7 winds up the reflective cloth strip 6 until the universal wheel 5 moves to fit the ground and lifts the bottom plate 1 away from the ground, and then the electric telescopic rod 2 can be stopped, and then the bottom plate 1 is moved, and the bottom plate 1 drives the universal wheel 5 to roll on the ground, so that the device moves to the measuring position. After the device moves to a suitable position, water is poured into the water tank 11, and the water level is flush with the bottom of the water tank 11. Then the electric telescopic rod 2 is controlled to extend, and the electric telescopic rod 2 drives the mounting plate 4 and the universal wheel 5 to move. The universal wheel 5 moves away from the ground so that the bottom plate 1 is in contact with the ground, thereby fixing the device to prevent the device from shifting during measurement. The mounting plate 4 moves to pull the reflective cloth strip 6 to unfold the reflective cloth strip 6. When the reflective cloth strip 6 is unfolded, the winding shaft 7 is driven to rotate, and the winding shaft 7 squeezes the plane scroll spring 9. When the electric telescopic rod 2 drives the water tank 11 and the distance sensor 28 to move upward to the measuring position, the electric telescopic rod 2 stops working. At this time, the reflective cloth strip 6 is unfolded to play a reflective warning role, that is, when the electric telescopic rod 2 is working, the universal wheel 5 can be moved away from the ground to fix the device, and the reflective cloth strip 6 can be unfolded to play a reflective warning role. At the same time, the height of the distance sensor 28 can also be adjusted, achieving three goals in one go, and the operation is more convenient.

[0051] The water inside the water tank 11 can adjust the horizontal state of the distance sensor 28. When the ground where the bottom plate 1 is located is not in a horizontal state, the water inside the water tank 11 drives the annular floating plate 13 to float, so that the annular floating plate 13 is in a horizontal state. When the annular floating plate 13 swings to the left or right due to the floating of the water surface, the annular floating plate 13 drives the threaded column 17 to swing. The threaded column 17 swings around the second round rod 21. The setting of the slot 18 allows space for the first round rod 19 when the threaded column 17 swings. When the annular floating plate 13 swings forward or backward due to the floating of the water surface, the annular floating plate 13 drives the second round rod 21 to swing through the threaded column 17. The second round rod 21 drives the roller 23 to roll in the inner cavity of the limit groove 26, so as to adjust the horizontal state of the distance sensor 28. Then, the distance sensor 28 is adjusted to send a signal. After the signal receiving end receives the signal, the measured height is obtained.

[0052] After the measurement work is completed, the electric telescopic rod 2 is controlled to shorten, and the winding shaft 7 is used to reel in the reflective cloth strip 6 until the universal wheel 5 moves to fit the ground, and the bottom plate 1 is lifted up to away from the ground, and then the anti-slip strip 16 on the threaded tube 15 is rotated and held, and the threaded tube 15 is rotated. The threaded tube 15 rotates on the outer edge of the threaded column 17, and moves upward under the action of the thread of the threaded tube 15. The threaded tube 15 drives the annular floating plate 13 to move upward, and the annular floating plate 13 moves upward to fit the top of the inner cavity of the water tank 11. The annular floating plate 13 blocks the circular hole 12 to prevent water from spilling out of the water tank 11 when the device is transferred, and at the same time prevents the ranging sensor 28 from swinging and being hit during the transfer process, thereby protecting the ranging sensor 28.

7. A bridge engineering height measuring device with warning function as claimed in claim 1, characterized in that: The limiting groove (26) and the roller (23) match each other, and the roller (23) is movably connected to the inner cavity of the adjacent limiting groove (26).

8. A bridge engineering height measuring device with warning function as claimed in claim 1, characterized in that: The arc-shaped plate (25) is fixedly connected to the top of the water tank (11), and a baffle (27) is fixedly connected to the top of the arc-shaped plate (25).

9. A method for a bridge engineering height measuring device with a warning function according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: First, the electric telescopic rod (2) is controlled to shorten, and the electric telescopic rod (2) drives the mounting plate (4) to move downward through the connecting plate (3), and the mounting plate (4) drives the universal wheel (5) to move downward, and at the same time, the plane scroll spring (9) is wound, and the plane scroll spring (9) drives the winding shaft (7) to rotate when winding, and the winding shaft (7) winds the reflective cloth strip (6) until the universal wheel (5) moves to fit the ground and lifts the bottom plate (1) away from the ground, and then the electric telescopic rod (2) stops working; Step 2: Then move the bottom plate (1), and the bottom plate (1) drives the universal wheel (5) to roll on the ground, so that the device moves to the measurement position. After the device moves to the appropriate position, water is poured into the water tank (11), and the water level is flush with the bottom of the water tank (11); Step 3: Then, the electric telescopic rod (2) is controlled to extend, and the electric telescopic rod (2) drives the mounting plate (4) and the universal wheel (5) to move, and the universal wheel (5) moves away from the ground, so that the bottom plate (1) is in contact with the ground, thereby fixing the device to prevent the device from shifting during measurement, and the mounting plate (4) moves to pull the reflective cloth strip (6), and unfold the reflective cloth strip (6). When the reflective cloth strip (6) is unfolded, it drives the winding shaft (7) to rotate, and the winding shaft (7) squeezes the plane scroll spring (9). When the electric telescopic rod (2) drives the water tank (11) and the distance measuring sensor (28) to move upward to the measuring position, the electric telescopic rod (2) stops working, and at this time, the reflective cloth strip (6) is unfolded to play a reflective warning role; Step 4: The water inside the water tank (11) can adjust the horizontal state of the distance measuring sensor (28). When the ground where the bottom plate (1) is located is not in a horizontal state, the water inside the water tank (11) drives the annular floating plate (13) to float, so that the annular floating plate (13) is in a horizontal state. When the annular floating plate (13) swings to the left or right due to the floating of the water surface, the annular floating plate (13) drives the threaded column (17) to swing. The threaded column (17) swings around the second round rod (21). The arrangement of the slot (18) allows the first round rod (19) to have space when the threaded column (17) swings. When the annular floating plate (13) swings forward or backward due to the floating of the water surface, the annular floating plate (13) drives the second round rod (21) to swing through the threaded column (17). The second round rod (21) drives the roller (23) to roll in the inner cavity of the limit groove (26), thereby adjusting the horizontal state of the distance measuring sensor (28). Step 5: Then adjust the distance measuring sensor (28) to send a signal, and after the signal receiving end receives the signal, the measured height is obtained; Step 6: After the measurement work is completed, the electric telescopic rod (2) is controlled to shorten, and the winding shaft (7) is used to reel in the reflective cloth strip (6) until the universal wheel (5) moves to fit the ground, and the bottom plate (1) is lifted up to be away from the ground, and then the anti-slip strip (16) on the threaded tube (15) is rotated and held, and the threaded tube (15) is rotated. The threaded tube (15) rotates on the outer edge of the threaded column (17), and moves upward under the action of the thread of the threaded tube (15). The threaded tube (15) drives the annular floating plate (13) to move upward, and the annular floating plate (13) moves upward to fit the top of the inner cavity of the water tank (11). The annular floating plate (13) blocks the circular hole (12) to prevent the water inside the water tank (11) from spilling out when the device is transferred, and also prevents the distance sensor (28) from swinging and being hit during the transfer process, thereby protecting the distance sensor (28).
