Description

Technical Field

[0001] The invention relates to the technical field of bridge measurement, in particular to a settlement measurement device used for bridge design. Background Art

[0002] With the rapid advancement of transportation infrastructure construction, many new bridges have been built in various parts of the country. Since bridge piers may sink and move during construction and use, if the value is large, it will directly affect the service life of the bridge and the safety of driving, and remedial measures should be taken in time. In order to determine the value of its deformation, the bridge should be periodically observed for settlement and displacement;

[0003] According to a Chinese patent with application publication number CN114234913A, a settlement measuring device for bridge design is disclosed. A supporting settlement plate is set up around the settlement mark of the bridge pier, and the center of the settlement plate is facing the settlement mark. A settlement monitoring mechanism is set under the settlement plate to monitor the settlement plate descent data for a long time and obtain the settlement of the bridge. The settlement plate is supported by a uniformly distributed pressure-stabilizing support mechanism, and a level measuring mechanism is installed on the pressure-stabilizing support mechanism to monitor whether the settlement plate is tilted and obtain the direction and data of the pier tilt offset. After using the settlement measuring device designed for the above-mentioned bridge, we found that due to the randomness of the settlement of the bridge piers, it is impossible to predict the direction of the pier inclination and settlement, and the above-mentioned device cannot measure the direction angle of the pier inclination, resulting in the designers being unable to know the pier inclination direction angle data. At the same time, after installation, the device can only measure the left and right inclination angles of the installation viewing angle. However, due to the randomness factor of the pier inclination settlement direction angle, the device cannot measure the inclination angle of the pier in any direction, and the scope of use is narrow. We propose a method to solve the above-mentioned technical problems. Summary of the invention

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. In the present invention, if the bridge pier sinks obliquely, the sheet metal frame is guided by the guide part to rotate along the top of the protractor and move in the inclination direction of the bridge pier. During this period, the direction angle sensor continuously collects the scale signal from the top of the protractor until the sheet metal frame stops moving. The direction angle sensor records the scale of the stop position and transmits the detection data to an external computer, thereby knowing the direction angle of the bridge's inclination and settlement.

[0042] 2. In the present invention, if the bridge pier tilts and settles, the counterweight effect of the trigger part and the counterweight part causes the axle pin to rotate along the sheet metal frame. The rotation of the axle pin drives the driving gear to rotate together. The rotation of the driving gear further drives the driven gear together with the driven shaft to rotate. The rotation of the driven shaft drives the angle plate to rotate. The rotation angle of the angle plate is collected by the inclination sensor, and the rotation angle signal is transmitted to the external computer, so as to know the inclination and settlement angle of the bridge pier.

[0043] 3. In the present invention, the gear ratio of the driving gear to the driven gear is set to 5:1, so that after the driving gear rotates a slight angle, the rotation angle of the driven gear will not be too small, thereby avoiding the risk that the angle plate is not easily captured by the inclination sensor due to the small rotation angle, thereby improving the measurement accuracy.

[0044] 4. In the present invention, the counterweight part acts on the bottom of the trigger rod, so that the trigger rod is always kept perpendicular to the horizontal plane. That is to say, when the bridge pier is tilted, there is an angle between the axis of the trigger rod and the normal of the ball slider, so that the gravity of the counterweight generates a component force along the normal direction of the ball slider through the connection of the suspension wire rope, the trigger rod and the sheet metal frame, thereby making it easier to trigger the ball slider to slide along the arc guide rail.

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.

[0056] Please refer to Figures 1 to 9, the technical solution provided by the present invention specifically includes the following embodiments:

[0057] A settlement measurement device for bridge design, comprising:

[0058] A direction angle measuring unit 100, which is used to measure the direction of bridge settlement;

[0062] The inclination measuring unit 500 is used to measure the settlement angle of the bridge. The inclination measuring unit 500 is installed on the surface of the direction angle measuring unit 100;

[0063] A triggering unit 600, the triggering unit 600 is used to derive the inclination measuring unit 500, and the triggering unit 600 is located at the bottom of the inclination measuring unit 500;

[0064] The direction angle measuring unit 100 includes:

[0065] A sheet metal frame 101, wherein a mounting thread hole 102 is provided on the top of the sheet metal frame 101, and an angular direction sensor 103 is installed on the inner thread of the mounting thread hole 102, and the angular direction sensor 103 is used for measuring the moving direction angle of the sheet metal frame 101;

[0066] There are two bevel gauges 104 , and the two bevel gauges 104 are combined into a “circular ring” structure. The bevel gauge 104 is located at the bottom of the direction angle sensor 103 , and a scale value is set on the upper surface of the bevel gauge 104 .

[0067] If the bridge pier sinks obliquely, the sheet metal frame 101 will rotate along the top of the protractor 104 and move in the inclination direction of the bridge pier under the guidance of the guide part 200. During this period, the direction angle sensor 103 will continuously collect the scale signal of the top of the protractor 104 until the sheet metal frame 101 stops moving. The direction angle sensor 103 records the scale of the stop position and transmits the detection data to an external computer, thereby knowing the direction angle of the bridge's inclination and settlement.

[0068] Refer to Figure 2. Fig. 9 As shown, the guide portion 200 includes:

[0069] Two arc guide rails 201 distributed opposite to each other, the two arc guide rails 201 are concentric with the centers of the two protractors 104, and the two arc guide rails 201 are located on top of the two protractors 104;

[0070] Ball sliders 202 are slidably mounted on the periphery of the two arc-shaped guide rails 201 . The top of the ball sliders 202 is fixedly connected to the top wall of the sheet metal frame 101 by bolts. The ball sliders 202 are used to support and guide the sheet metal frame 101 .

[0071] Through the sliding connection between the ball slider 202 and the arc guide rail 201, the sheet metal frame 101 is provided with precise guiding effect, thereby ensuring the stability of the sheet metal frame 101. At the same time, after the two arc guide rails 201 are combined, the ball slider 202 can move around along the periphery of the two arc guide rails 201, ensuring that after the bridge pier tilts and settles in any direction, the ball slider 202 can drive the sheet metal frame 101 to move in the tilt direction, and the measuring range is wide.

[0072] A positioning thread hole 203 is formed through the top of the ball slider 202, and a positioning screw 204 is connected to the inner thread of the positioning thread hole 203. The positioning screw 204 is connected to the thread of the positioning thread hole 203, so that the ball slider 202 can be limited to the top of the arc guide rail 201, so that the device can be idle and the ball slider 202 can not move freely on the top of the arc guide rail 201. When in use, the positioning screw 204 needs to be loosened to ensure the free movement of the ball slider 202.

[0073] 2 and 3 , the bearing portion 300 includes:

[0074] Two arc-shaped bearing frames 301 are arranged opposite to each other, and the two arc-shaped bearing frames 301 are combined into a "circular ring" structure. The arc-shaped bearing frames 301 are located at the bottom of the arc-shaped guide rail 201, and the arc-shaped bearing frames 301 are concentric with the arc-shaped guide rail 201. The arc-shaped bearing frames 301 and the arc-shaped guide rail 201 are fixedly connected by bolts, and the arc-shaped bearing frames 301 are used to support and fix the arc-shaped guide rail 201;

[0075] The load-bearing cantilever frame 302 , the number of the load-bearing cantilever frames 302 is multiple, the multiple load-bearing cantilever frames 302 are distributed in a fan shape, and the multiple load-bearing cantilever frames 302 are fixedly installed at the bottom of the arc-shaped load-bearing frame 301 , and the load-bearing cantilever frames 302 are used to fix the arc-shaped load-bearing frame 301 .

[0076] By setting up two arc-shaped supporting frames 301, the two arc-shaped guide rails 201 are fixedly supported to ensure the stability of the two arc-shaped guide rails 201. At the same time, a supporting frame 302 is set to provide support for the arc-shaped supporting frame 301 to ensure the stability of the arc-shaped supporting frame 301. By setting up multiple fan-shaped supporting frames 302, the supporting force for the arc-shaped supporting frame 301 can be more comprehensive, thereby improving the overall support for the arc-shaped supporting frame 301.

[0077] 2, the positioning unit 400 includes:

[0078] Two arc-shaped positioning plates 401 are arranged opposite to each other, and the two arc-shaped positioning plates 401 are combined into a "circular" structure. The centers of the two arc-shaped positioning plates 401 are concentric with the arc-shaped support frame 301. The outer walls of the arc-shaped positioning plates 401 are welded and fixed to the ends of the support frame 302. The outer walls of the arc-shaped positioning plates 401 are penetrated with tensioning wire holes 402, and the tensioning wire holes 402 are located between two adjacent support frames 302.

[0079] A positioning screw 403 is screwed onto the inner thread of the tensioning wire hole 402, and the positioning screw 403 is used for tensioning the arc-shaped positioning plate 401;

[0080] Positioning rubber block 404: The inner end of the positioning screw rod 403 is fixedly mounted with a positioning rubber block 404, and the positioning rubber block 404 is used to increase friction;

[0081] Both ends of the arc-shaped positioning plate 401 are penetrated by connecting holes 405 .

[0082] The two arc guide rails 201 are fixedly installed on the top of the two arc bearing frames 301 by bolts, and the ball sliders 202 are slidably installed on the periphery of the two arc guide rails 201. Then, the two arc positioning plates 401 are assembled on the periphery of the bridge pier, so that the two arc positioning plates 401 are surrounded on the periphery of the bridge pier, and are assembled inside the through holes 405 by connecting bolts to fasten the two arc positioning plates 401 together to prevent the two arc positioning plates 401 from being separated again. Then, the two arc positioning plates 401 are tightened along the tension wire holes 405. 2, the positioning screw rod 403 is tightly fixed inside, the positioning rubber block 404 is pressed against the outer surface of the pier, and the device is positioned between the pier by the friction between the four positioning rubber blocks 404 and the pier. The arc positioning plate 401 is fixed, that is, the two arc bearing frames 301 together with the two arc guide rails 201 are fixed by multiple bearing cantilevers 302. At the same time, the screw-in length of the positioning screw rod 403 can be adjusted, which can be suitable for the settlement measurement of piers of different thicknesses.

[0083] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the inclination measuring unit 500 includes:

[0084] Axle pin 501, which is rotatably mounted inside the sheet metal frame 101;

[0085] A driving gear 502 is fixedly mounted on one end of the shaft pin 501, a driven gear 504 is meshed at the bottom of the driving gear 502, a driven shaft 503 is fixedly mounted on the inner wall of the driven gear 504, the driven shaft 503 is rotatably mounted on the outer surface of the sheet metal frame 101, an angle plate 505 is fixedly mounted on the end of the driven shaft 503, and the gear ratio of the driving gear 502 to the driven gear 504 is 5:1;

[0086] The inclination sensor 506 is fixedly mounted on the outer surface of the sheet metal frame 101 through a fixing bracket. The inclination sensor 506 is matched with the angle plate 505 in position and specification.

[0087] If the pier tilts and settles, the trigger part 600 and the counterweight part 700 will cause the axle pin 501 to rotate along the sheet metal frame 101. The rotation of the axle pin 501 drives the driving gear 502 to rotate together. The rotation of the driving gear 502 further drives the driven gear 504 and the driven shaft 503 to rotate. The rotation of the driven shaft 503 drives the angle plate 505 to rotate. The rotation angle of the angle plate 505 is collected by the inclination sensor 506, and the rotation angle signal is transmitted to the external computer, so as to know the inclination and settlement angle of the pier. It should be noted that since the gear ratio of the driving gear 502 and the driven gear 504 is 5:1, after the driving gear 502 rotates a small angle, the rotation angle of the driven gear 504 will not be too small, thereby avoiding the risk that the angle plate 505 is not easily captured by the inclination sensor 506 due to the small rotation angle, thereby improving the measurement accuracy.

[0088] Reference Figure 4 , Figure 7 and Figure 8 As shown, the trigger unit 600 includes:

[0089] Positioning pin 601, two positioning pins 601 are fixedly installed in the middle of the outer wall of the shaft pin 501, and the two positioning pins 601 are symmetrically distributed about the center of the shaft pin 501. The outer walls of the two positioning pins 601 are rotated together to install a U-shaped connecting flange 602, and the bottom of the U-shaped connecting flange 602 is provided with a connecting hole 603;

[0090] A trigger rod 604 is welded inside the connecting hole 603 , and the trigger rod 604 is used to trigger the shaft pin 501 to rotate.

[0091] If the bridge pier tilts and settles, the trigger rod 604 is subjected to the counterweight effect of the counterweight part 700, and the trigger rod 604 realizes the universal rotation effect of the trigger rod 604 through the rotation connection effect of the U-shaped connecting flange 602 and the positioning pin 601, and the rotation connection of the shaft pin 501 and the sheet metal frame 101, so that after the bridge pier tilts to any angle, the trigger rod 604 is always guaranteed to be vertical to the horizontal plane. Therefore, if the bridge pier tilts and settles, the shaft pin 501 will rotate along the sheet metal frame 101, and the rotation of the shaft pin 501 drives the driving gear 502 to rotate together, and the rotation of the driving gear 502 further drives the driven gear 504 and the driven shaft 503 to rotate, and the rotation of the driven shaft 503 drives the angle plate 505 to rotate together, and the rotation angle of the angle plate 505 is collected by the inclination sensor 506, and the rotation angle signal is transmitted to the external computer, so as to know the tilt settlement angle of the bridge pier;

[0092] In addition, the counterweight part 700 acts on the bottom of the trigger rod 604 to ensure that the trigger rod 604 is always perpendicular to the horizontal plane. That is to say, when the pier is tilted, there is an angle between the axis of the trigger rod 604 and the normal of the ball slider 202, causing the gravity of the counterweight 702 to generate a component force along the normal direction of the ball slider 202 through the connection between the suspension wire rope 701, the trigger rod 604 and the sheet metal frame 101, thereby making it easier to trigger the ball slider 202 to slide along the arc guide rail 201.

[0093] Reference Figure 4 , Figure 8 As shown, it also includes a counterweight portion 700, and the counterweight portion 700 includes:

[0094] A suspension wire rope 701, the suspension wire rope 701 is connected to the bottom of the trigger rod 604;

[0095] A counterweight 702 is fixedly connected to the bottom of the suspension wire rope 701 , and the counterweight 702 is used to counterweight the trigger rod 604 .

[0096] By arranging a counterweight 702 at the bottom of the trigger rod 604, the weight of the bottom of the trigger rod 604 is increased, so that the overall center of gravity of the trigger rod 604 and the counterweight 702 is located at the lower part of the trigger rod 604, ensuring that the trigger rod 604 can always remain perpendicular to the horizontal plane, and the trigger rod 604 is connected to the counterweight 702 by a suspension wire rope 701, so that when the device is not in use, the suspension wire rope 701 can be wound around the outer wall of the trigger rod 604, thereby reducing the volume and facilitating the assembly and transportation of the device.

[0097] Reference Figure 4 , Figure 5 As shown, the horizontal detection unit 800 is also included, and the horizontal detection unit 800 includes:

[0098] The sheet metal bending frame 801 is fixedly mounted on the side of the sheet metal frame 101 by bolts;

[0099] Electronic level 802: An electronic level 802 is fixedly installed on the top of the sheet metal bending frame 801, and the electronic level 802 is used to detect the level of the arc-shaped supporting frame 301.

[0100] Before tightening the four positioning screws 403, it is necessary to measure the horizontality using the electronic level 802. If the arc positioning plate 401 is in a non-horizontal state, the electronic level 802 will issue an alarm. At this time, the two arc positioning plates 401 are adjusted until the electronic level 802 senses that the two arc positioning plates 401 are in a horizontal state, cancel the alarm, and then tighten the four positioning screws 403 to ensure that the four positioning rubber blocks 404 are tightly in contact with the outer side of the pier to prevent the device from slipping.

[0101] In the present scheme, a settlement measurement device for bridge design is used. When working, two arc guide rails 201 are fixedly installed on the top of two arc bearing frames 301 by bolts, and at the same time, the ball slider 202 is slidably installed on the periphery of the two arc guide rails 201. Then, two arc positioning plates 401 are assembled on the periphery of the bridge pier, so that the two arc positioning plates 401 are surrounded on the periphery of the bridge pier, and are assembled inside the through-hole 405 by connecting bolts to fasten the two arc positioning plates 401 together to prevent the two arc positioning plates 401 from being separated again. Then, the positioning screw rod 403 is tightened along the inside of the tensioning wire hole 402 to press the positioning rubber block 404 against the bridge pier. On the outer surface of the bridge pier, the device is positioned between the bridge pier by using the friction between the four positioning rubber blocks 404 and the bridge pier. It should be noted that before tightening the four positioning screw rods 403, it is necessary to measure the horizontality by the electronic level 802. If the arc positioning plate 401 is in a non-horizontal state, the electronic level 802 will issue an alarm. At this time, the two arc positioning plates 401 are adjusted until the electronic level 802 senses that the two arc positioning plates 401 are in a horizontal state, the alarm is canceled, and the four positioning screw rods 403 are screwed and tightened to ensure that the four positioning rubber blocks 404 are tightly in contact with the outer side of the bridge pier to prevent the device from sliding down.

[0102] After the two arc-shaped positioning plates 401 are assembled, the two arc-shaped bearing frames 301 are combined into a ring structure through the connection of the multiple bearing frames 302, and the two arc-shaped guide rails 201 are further combined into a ring structure through the two arc-shaped bearing frames 301, so that the ball sliders 202 can move along the two ball sliders 202.

[0103] After the installation is completed, the direction angle sensor 103 and the inclination sensor 506 of the device are reset to zero, and the device and the bridge pier are left still for a period of time. If the bridge pier sinks obliquely, first, under the action of gravity of the ball slider 202, it will slide along the two arc-shaped guide rails 201 in the inclination direction of the bridge pier. In addition, due to the rotation connection between the trigger rod 604 and the positioning pin 601 through the U-shaped connecting flange 602, and the rotation connection between the axle pin 501 and the sheet metal frame 101, the universal rotation of the trigger rod 604 is realized, so that after the bridge pier is tilted to any angle, the counterweight 702 on the bottom of the trigger rod 604 keeps the trigger rod 604 vertical to the horizontal plane. That is to say, when the bridge pier is tilted, the trigger rod 604 is in a state of being ... There is an angle between the axis of the rod 604 and the normal of the ball slider 202, so that the gravity of the counterweight 702 generates a component force along the normal direction of the ball slider 202 through the connection of the suspension wire rope 701, the trigger rod 604 and the sheet metal frame 101, so that it is easier to trigger the ball slider 202 to slide along the arc guide rail 201. The sliding of the ball slider 202 drives the direction angle sensor 103 to rotate along the top of the bevel gauge 104. During this period, the direction angle sensor 103 continuously collects the scale signal of the top of the bevel gauge 104 until the ball slider 202 stops sliding. The direction angle sensor 103 records the scale of the stop position and transmits the detection data to the external computer, thereby knowing the direction angle of the bridge tilt settlement;

[0104] At the same time, due to the inclination and settlement of the bridge pier, the trigger rod 604 is always kept perpendicular to the horizontal plane by the counterweight of the counterweight 702. Therefore, the axle pin 501 will rotate along the sheet metal frame 101. The rotation of the axle pin 501 drives the active gear 502 to rotate together. The rotation of the active gear 502 further drives the driven gear 504 and the driven shaft 503 to rotate. The rotation of the driven shaft 503 drives the angle plate 505 to rotate. The rotation angle of the angle plate 505 is collected by the inclination sensor 506, and the rotation angle signal is transmitted to the external computer, so as to know the inclination and settlement angle of the bridge pier. It should be noted that since the gear ratio of the active gear 502 and the driven gear 504 is 5:1, after the active gear 502 rotates a slight angle, the rotation angle of the driven gear 504 will not be too small, thereby avoiding the risk that the angle plate 505 is not easily captured by the inclination sensor 506 due to the small rotation angle, thereby improving the measurement accuracy.
