[0001] The present invention belongs to the technical field of detection equipment, and in particular relates to a bridge support height detection device. Background Art

[0002] Bridge supports are set between the bridge and the piers supporting the bridge. During the operation of the bridge, vehicles will pass over the bridge, causing the bridge supports to be subjected to corresponding pressure. As time goes by, the bridge supports will experience reduced bearing capacity and deformation, which will affect the stability of the bridge and may even cause the bridge to overturn in severe cases.

[0003] To ensure the normal operation of the bridge, staff will regularly use measuring tools or distance meters and other detection devices to test the height of each part of the bridge support (multiple positions in the circumferential direction), obtain the measured height value of each part of the bridge support, and compare the measured height value with the initial height value of each part of the bridge support to accurately determine the deformation of each part of the bridge support; However, for piers installed on an inclined slope, if the inspection space between the lower surface of the bridge and the inclined slope is small and cannot accommodate personnel, see Figure 1 , it is difficult for the staff to detect the height of the bridge bearing and cannot accurately measure the height value of the bridge bearing, which makes it impossible for the staff to accurately understand the deformation of the bridge bearing.

[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise specified, the term "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front," "rear," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention depending on the specific circumstances.

[0031] In the embodiments of the present application, Figures 2 to 10 As shown, the bridge support height detection device includes an upper guide rail 1, a lower guide rail 2 and a detection component 3; wherein, The upper guide rail 1 and the lower guide rail 2 are circular guide rails with equal radius. The upper guide rail 1 and the lower guide rail 2 are sleeved on the bridge support 5, and the axes of the upper guide rail 1, the lower guide rail 2 and the bridge support 5 coincide. The plane where the upper guide rail 1 and the plane where the lower guide rail 2 are located are flush with the upper end surface and the lower end surface of the bridge support 5 respectively. Both ends of the detection component 3 are slidably disposed on the upper guide rail 1 and the lower guide rail 2 , respectively, and can slide along the upper guide rail 1 and the lower guide rail 2 .

[0032] When the detection component 3 slides along the upper guide rail 1 and the lower guide rail 2, the height value of the circumferential position of the bridge support 5 can be measured; preferably, the detection component 3 is connected to the terminal signal. The terminal in this embodiment is a computer, a smart phone or a tablet computer, and the detection component 3 and the terminal can achieve signal connection through wireless connection methods commonly used in the prior art such as wireless network, infrared or Bluetooth; Specifically, the staff can control the detection component 3 to move along the upper guide rail 1 and the lower guide rail 2 through the terminal. When the detection component 3 stops moving, the detection component 3 can detect the distance between the upper guide rail 1 and the lower guide rail 2 at that position (the position where the detection component 3 stops) to obtain the distance value between the upper guide rail 1 and the lower guide rail 2, and send the detection structure (distance value) to the terminal. Since the planes where the upper guide rail 1 and the lower guide rail 2 are located are flush with the upper end face and the lower end face of the bridge support 5 respectively, that is, the distance value between the upper guide rail 1 and the lower guide rail 2 is equal to the height value of the circumferential position of the bridge support, the height value of the circumferential position of the bridge support can be obtained by the obtained distance value. After the height value detection at this position is completed, the staff can continue to control the detection component 3 to move along the extension direction of the upper guide rail 1, and repeat the above steps to complete the detection of the circumferential height of the bridge support 5.

[0033] Of course, the bridge support height detection device can also control the detection component 3 to move and detect the distance between the upper guide rail 1 and the lower guide rail 2 at the same time through the terminal, that is, the detection component 3 completes the detection of the distance between the upper guide rail 1 and the lower guide rail 2 during the movement process, and stops after the detection component 3 moves around the bridge support 5 for one circle, completing the detection of the distance between the upper guide rail 1 and the lower guide rail 2 at all circumferential positions, and sending the detection results to the terminal.

[0034] The bridge support height detection device can be installed on the bridge support 5 together with the installation of the bridge support 5. The planes where the upper guide rail 1 and the lower guide rail 2 are located are flush with the upper end face and the lower end face of the bridge support 5 respectively. That is, by measuring the spacing value between any position of the upper guide rail 1 and the lower guide rail 2, the height value of the bridge support 5 and the corresponding side of the detection position can be obtained. The detection component 3 can slide along the upper guide rail 1 and the lower guide rail 2, so that the detection component 3 can measure the height of any circumferential position of the bridge support 5 to easily obtain the accurate height value of the bridge support 5. During the entire detection process, there is no need for staff to enter the detection space. Even when the detection space between the lower surface of the bridge and the inclined slope is small, the accurate height value of the bridge support 5 can be obtained, thereby accurately understanding the deformation of the bridge support 5.

[0035] Of course, the bridge support height detection device can also be used to detect the height of bridge supports on common piers. Workers do not need to climb to the top of the pier to detect the height of the bridge support, so as to improve the safety of the detection process and reduce the labor intensity of bridge support height detection.

[0036] It is worth noting that the detection component 3 in the bridge support height detection device can still obtain the height detection of the circumferential position of the bridge support 5 even if it is not connected to the terminal signal, that is, the measured data value is stored during the detection process until the detection component 3 moves to a larger space between the lower surface of the bridge and the inclined slope (on the opposite side of the detection space). The staff can remove the detection component 3 and use a laptop, tablet computer or smart phone and other devices to connect the detection component 3 signal to read the detected spacing value, and obtain an equal amount of bridge support circumferential position height value through the obtained spacing value.

[0037] Optimized, the bridge support height detection device also includes an upper steel plate 6 and a lower steel plate 7, see Figure 2 ;in, The upper steel plate 6 and the lower steel plate 7 are respectively arranged at the two ends of the bridge support 5, and the upper guide rail 1 and the lower guide rail 2 are respectively arranged on the opposite surfaces of the upper steel plate 6 and the lower steel plate 7 to ensure that the plane where the upper guide rail 1 is located and the plane where the lower guide rail 2 is located are always flush with the upper end face and the lower end face of the bridge support 5. Even if the bridge support 5 is tilted and deformed (the strength of one side is reduced, resulting in an angle between the upper end face and the lower end face of the bridge support 5 being greater than 0°), the upper guide rail 1 and the lower guide rail 2 can also move synchronously with the upper steel plate 6 and the lower steel plate 7 along with the upper end face and the lower end face of the bridge support 5 to ensure the accuracy of the detection of the bridge support height detection device.

[0038] In some embodiments, the detection assembly 3 includes a drive assembly 33, and the drive assembly 33 includes a drive motor 331 and a gear ring 332. Figure 3 ;in, The radius of the gear ring 332 is equal to the radius of the upper guide rail 1. A first slide groove is provided on the side of the upper guide rail 1 facing the detection component 3. The extension direction of the first slide groove is the same as the extension direction of the upper guide rail 1, that is, the radius of the first slide groove is equal to the radius of the upper guide rail 1. The gear ring 332 is rotatably provided in the upper guide rail 1 around the axis of the upper guide rail 1. One end of the detection component 3 is connected to the gear ring 332. The driving end of the driving motor 331 is provided with a driving gear 333 , which is meshed with the gear ring 332 ; The driving motor 331 is connected to the terminal signal, and the staff can control the action of the driving motor 331 through the terminal to drive the detection component 3 to move along the extension direction of the upper guide rail 1 to realize the detection of the circumferential height of the bridge support 5.

[0039] Optimally, a second chute is provided on the side of the lower guide rail 2 facing the detection component 3. The extension direction of the second chute is the same as that of the lower guide rail 2. One end of the detection component 3 is slidably provided in the second chute along the extension direction of the second chute. The position of the detection component 3 is limited by the first chute and the second chute to more accurately detect the circumferential height value of the bridge support 5. In this embodiment, a pulley is provided at one end of the detection component 3 located in the second chute to reduce the friction of the detection component 3 during movement, thereby making the movement of the detection component 3 more stable and smooth.

[0040] In some embodiments, the detection assembly 3 further includes an electronic locator 34, a distance sensor 35, a detection sleeve 31 and two detection rods 32; wherein, The detection sleeve 31 is a tubular structure with two openings at both ends. Two detection rods 32 are inserted into the detection sleeve 31 through the openings at both ends to form a detection body. The ends of the two detection rods 32 away from the detection sleeve 31 are respectively connected to the gear ring 332 and the pulley. Figure 4 ; The two detection rods 32 can move along the length direction of the detection sleeve 31 (moving toward the middle of the detection sleeve 31, or moving away from the middle of the detection sleeve 31), so as to change the length of the detection body. During the movement, the height of the circumferential position of the bridge support 5 can be detected. When the bridge support 5 is deformed, the detection body can also smoothly pass through the deformed part by changing its length and detect the height of the deformed part; The transmitting end and reflecting end of the distance sensor 35 are respectively arranged on the side walls of the two detection rods 32, see Figure 4 , and is arranged close to the end of the detection rod 32 away from the detection sleeve 31. The distance sensor 35 calculates the distance between the transmitting end and the reflecting end by the time it takes for the signal emitted by its transmitting end to be reflected back by the reflecting end. The transmitting end and the reflecting end of the distance sensor 35 are respectively arranged at the ends of the two detection rods 32 away from the detection sleeve 31 (the ends respectively connected to the upper guide rail 1 and the lower guide rail 2) to measure the distance between the upper guide rail 1 and the lower guide rail 2, so as to accurately obtain the height value of the bridge support 5; the above-mentioned distance sensor 35 can be an optical distance sensor 35, an infrared distance sensor 35, an ultrasonic distance sensor 35, etc. The electronic locator 34 can be provided on the detection rod 32 or the detection sleeve 31 to determine the position of the detection subject on the bridge support 5, so that the staff can accurately determine the current position of the detection subject, and when the deformation position of the bridge support 5 is detected, the deformation position can be quickly determined according to the electronic locator 34; The electronic locator 34 and the distance sensor 35 are both connected to the terminal signal, and the terminal receives the position information of the electronic locator 34 and the height information measured by the distance sensor 35.

[0041] It should be noted that the transmitting end and the reflecting end of the distance sensor 35 are respectively arranged at the ends of the two detection rods 32 to more accurately measure the distance between the upper guide rail 1 and the lower guide rail 3; If the ends of the two detection rods 32 do not meet the installation requirements of the distance sensor 35, Figure 3 As shown, when the first chute and the second chute cannot accommodate the distance sensor 35, the installation position of the distance sensor 35 can be moved toward the detection rod 32 in a direction close to the detection sleeve 31 until the distance sensor 35 can be firmly installed on the detection rod 32 without being affected by other structures; After this setting, when calculating the distance between the upper guide rail 1 and the lower guide rail 2, it is necessary to add the distance from the end of the detection rod 32 slidingly set in the upper guide rail 1 to the distance sensor 35 (transmitter end or reflector end) to the distance from the end of the detection rod 32 slidingly set in the lower guide rail 2 to the distance sensor 35 (reflector end or transmitter end), and then add the distance measured by the distance sensor 35 to obtain the distance between the upper guide rail 1 and the lower guide rail 2; Of course, when the distance sensor 35 is installed, the distance from one end of the detection rod 32 slidingly set in the upper guide rail 1 to the distance sensor 35 (transmitting end or reflecting end) and the distance from one end of the detection rod 32 slidingly set in the lower guide rail 2 to the distance sensor 35 (reflecting end or transmitting end) can be obtained, and the distance can be input into the terminal to make the subsequent calculation of the distance between the upper guide rail 1 and the lower guide rail 2 more convenient.

[0042] Preferably, the outer wall of the detection sleeve 31 is provided with a sliding hole communicating with the inner cavity, see Figure 4 and Figure 5 The length direction of the sliding hole is parallel to the length direction of the detection sleeve 31, and the above-mentioned electronic locator 34 is arranged on the side wall of the sliding hole corresponding to the detection rod 32; when the detection rod 32 slides along the length direction of the detection sleeve 31, the electronic locator 34 can slide along the length direction of the sliding hole; and the position of the detection rod 32 can be limited by the sliding hole, that is, the detection rod 32 can only move along the axial direction of the detection sleeve 31, and cannot rotate around the axis of the detection sleeve 31, so that the transmitting end and the reflecting end of the distance sensor 35 are always aligned to meet the requirements of distance detection.

[0043] In some embodiments, the inner cavity of the detection sleeve 31 is provided with an alarm trigger device, which is located in the middle of the length direction of the detection sleeve 31. Elastic members 37 are provided at both ends of the alarm trigger device, and the end of the elastic member 37 away from the alarm trigger device abuts against the detection rod 32. The alarm trigger device is connected to the terminal signal; When the deformation of the bridge support 5 is large, the end of the detection rod 32 away from the upper guide rail 1 or the lower guide rail 2 overcomes the elastic force of the elastic part 37 and moves toward the middle of the detection sleeve 31, and activates the alarm trigger device. The alarm trigger device will send an activation signal to the terminal. After receiving the activation signal, the terminal will issue an alarm message, prompting the staff to maintain or replace the bridge support 5 as soon as possible to avoid damage to the bridge support 5 and cause the bridge to overturn, thereby realizing the monitoring of the deformation of the bridge support 5.

[0044] After the detection component 3 passes the position where the deformation of the bridge support 5 is the largest, the elastic part 37 will push the detection rod 32 away from the center of the detection sleeve 31, so that the ends of the two detection rods 32 away from the detection sleeve 31 are always in contact with the upper guide rail 1 and the lower guide rail 2, ensuring the accuracy of the height measurement of the bridge support 5.

[0045] It is worth noting that the initial distance between the alarm trigger device and the detection rod 32 is the maximum value of the deformation that the bridge support 5 can withstand, as set by the bridge support height detection device. When the deformation of the bridge support 5 exceeds the maximum value of the deformation that the bridge support 5 can withstand, the detection rod 32 will contact and activate the alarm trigger device, prompting the staff to maintain and replace the bridge support 5 through the terminal to ensure the safety of bridge operation. The maximum value of the deformation that the bridge support 5 can withstand can be adjusted; wherein, The outer wall of the detection sleeve 31 is provided with an adjustment port that communicates with the inner cavity of the detection sleeve 31. The adjustment port is located in the middle of the length direction of the detection sleeve 31. The outer wall of the detection sleeve 31 is provided with an adjustment portion 38 at a position corresponding to the adjustment port. Both actuating ends of the adjustment portion 38 extend into the inner cavity of the detection sleeve 31. The two actuating ends of the adjustment portion 38 can move synchronously toward the ends or the middle of the detection sleeve 31. The above-mentioned alarm trigger device includes two trigger parts 36, and the two trigger parts 36 are respectively arranged at the two action ends of the adjustment part 38; by operating the adjustment part 38, the distance between the trigger part 36 and the detection rod 32 away from one end of the upper guide rail 1 or the lower guide rail 2 can be adjusted, that is, by operating the adjustment part 38, the maximum value of the deformation amount that the bridge support 5 can withstand can be adjusted, so that the bridge support height detection device can adapt to the monitoring of the deformation amount of different bridge supports 5 (bridge supports 5 with different heights, different bearing capacities and anti-deformation capabilities, etc.).

[0046] Specifically, the adjusting portion 38 includes a fixing block 381, an adjusting screw 382, an upper connecting plate 383 and a lower connecting plate 384, see Figure 5 、 Figure 9 and Figure 10 ; The fixing block 381 is provided at the adjustment opening, and a bayonet is provided on one side of the fixing block 381 corresponding to the adjustment opening; The adjusting screw 382 is provided with two threads with opposite spiral directions. The two threads extend from both ends of the adjusting screw 382 to the middle of the adjusting screw 382. The adjusting screw 382 is rotatably mounted on the fixed block 381. The axis of the adjusting screw 382 is parallel to the axis of the detection sleeve 31. The middle of the adjusting screw 382 is located in the bayonet. One end of the upper connecting plate 383 and the lower connecting plate 384 are both located in the bayonet, and respectively engage with two opposite threads on the adjusting screw 382 through threaded holes. The upper connecting plate 383 and the lower connecting plate 384 extend away from the end of the adjusting screw 382 into the inner cavity of the detection sleeve 31; The two trigger parts 36 are respectively provided on the upper connecting plate 383 and the lower connecting plate 384; When it is necessary to adjust the maximum value of the deformation that the bridge bearing 5 can withstand, the staff can turn the adjusting screw 382 to move the upper connecting plate 383 and the lower connecting plate 384 synchronously toward the two ends of the detection sleeve 31 (reducing the maximum value of the deformation that the bridge bearing 5 can withstand) or the middle (increasing the maximum value of the deformation that the bridge bearing 5 can withstand) to better adapt to the use of different bridge bearings 5.

[0047] In some embodiments, the trigger portion 36 includes a trigger seat 361, a contact block 362 and an activation module 363, see Figures 7 to 9 ;in, The trigger seat 361 is mounted on the upper connecting plate 383 or the lower connecting plate 384. A circular shaped accommodating cavity is defined within the trigger seat 361. The axis of the accommodating cavity coincides with the axis of the detection sleeve 31. A socket is defined at one end of the trigger seat 361 that faces the detection rod 32 and communicates with the accommodating cavity. The diameter of the socket is smaller than that of the accommodating cavity. The abutment block 362 is slidably disposed in the accommodating cavity along the radial direction of the accommodating cavity. A reset member 364 is disposed between the abutment block 362 and the side wall of the accommodating cavity to push the abutment block 362 toward the center of the accommodating cavity. A guide surface is disposed on the side of the abutment block 362 facing the socket. A trigger rod 321 capable of passing through the socket is disposed on the end of the detection rod 32 facing the trigger portion 36. The end surface of the trigger rod 321 away from the detection rod 32 is a spherical surface. There are two activation modules 363, which are respectively installed on the side of the abutment block 362 away from the center of the accommodating cavity and the side wall of the accommodating cavity, and both activation modules 363 are connected to the terminal signal; When the detection rod 32 continues to move toward the middle of the detection sleeve 31, the trigger rod 321 on the detection rod 32 will cooperate with the guide surface on the abutment block 362 to push the abutment block 362 away from the center of the accommodating chamber. When the detection rod 32 moves beyond the alarm distance, the abutment block 362 is pushed to the outer wall of the accommodating chamber by the trigger rod 321, and the activation module 363 on the abutment block 362 and the activation module 363 on the side wall of the accommodating chamber are in contact and connected, sending an activation signal to the terminal. When the deformation of one side of the bridge support 5 is greater than the maximum deformation that the bridge support 5 can withstand, that is, when the bridge support 5 is tilted and deformed, the detection body will be constrained by the upper guide rail 1 and the lower guide rail 2 during the movement toward the deformed position, and the detection rod 32 will move toward the center of the accommodating cavity along the axis direction of the detection sleeve 31; At this time, the spherical surface of the trigger rod 321 can cooperate with the guide surface to move the abutment block 362 away from the center of the accommodating cavity so that the two activation modules 363 contact each other, and the alarm trigger device is activated. The alarm trigger device will send an activation signal to the terminal, and the terminal will send an alarm message after receiving the activation signal.

[0048] It should be noted that the guide surface is inclined, and the distance between the guide surface close to the side wall of the accommodating cavity and the socket is smaller than the distance between the guide surface close to the center of the accommodating cavity and the socket; When the spherical surface of the trigger rod 321 abuts against the guide surface, as the detection rod 32 continues to move upward or downward, the abutment block 362 will move toward the side wall of the accommodating cavity under the cooperation of the spherical surface and the guide surface, thereby activating the alarm triggering device 36.

[0049] In some embodiments, the bridge support height detection device further includes a slide rail 4, which is a circular track with a radius equal to that of the upper guide rail 1 and is coaxially sleeved on the bridge support 5 and located between the upper guide rail 1 and the lower guide rail 2. Figure 2 and Figure 3 ; The detection sleeve 31 is slidably set on the slide rail 4 along the extension direction of the slide rail 4 through the fixed block 381 to ensure that the position of the detection sleeve 31 is always located in the middle of the bridge support 5 and its position will not change, so as to accurately detect the height value of the bridge support 5.

[0050] Optimally, a sliding opening is provided on the side of the fixing block 381 facing away from the detection sleeve 31 , and the fixing block 381 is slidably set on the slide rail 4 through the sliding opening, so that the fixing block 381 and the slide rail 4 are smoothly matched.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
