Description

A horizontal alignment detection device for rotating bridges Technical Field

[0001] This invention belongs to the field of rotating bridge inspection technology, and in particular relates to a horizontal alignment inspection device for rotating bridges. Background Technology

[0002] As an important structural form in bridge engineering that spans complex terrain and major transportation routes, the precise alignment of rotating bridges after rotation is a core element in ensuring the structural safety of the bridge and the quality of subsequent closure construction. Therefore, professional and precise alignment testing must be carried out after the rotation to provide reliable accuracy data support for subsequent closure construction, structural reinforcement, and other processes. This is an indispensable key quality control step in the construction of rotating bridges. In current engineering practice, for two rotating bridge sections with a distance of about four or five meters after rotation, the mainstream approach is to use optical testing instruments to detect the alignment degree. However, the detection principle is highly dependent on the linear propagation characteristics of light. The fog that is common in bridge construction scenarios can cause light refraction and scattering, and the dust generated during construction can also block and diffusely reflect the detection light. Both of these factors can seriously interfere with the transmission and reception of optical signals, leading to deviations in the detection data and making it difficult to meet the high-precision requirements of alignment testing for rotating bridges.

[0003] When optical inspection is constrained by environmental factors, mechanical contact inspection has become an alternative in some engineering scenarios. However, it also has significant technical defects in inspecting the four-to-five-meter span of a rotating bridge. The core of mechanical contact inspection relies on the rigid contact of the inspection rod to transmit position and axis information. However, for an inspection distance of four to five meters, the inspection rod needs to have a corresponding length. The long rod structure is prone to bending and deformation under its own weight, making it impossible to maintain a straight inspection baseline. Moreover, the amount of deformation will change with the length of the inspection rod and its own weight, making it difficult to accurately correct through subsequent calculations. This ultimately leads to the offset of the contact inspection point, the distortion of the axis judgment, and a significant decrease in inspection accuracy. It also cannot effectively guarantee the accuracy of alignment inspection of rotating bridges and is difficult to meet the quality control standards of engineering construction.

[0004] To address this issue, a horizontal alignment detection device for rotating bridges is proposed. Summary of the Invention

[0008] Preferably, the detection assembly includes a first electric push rod fixedly connected to the side wall of the rotating plate. The moving end of the first electric push rod passes through the rotating plate and is fixedly connected to an upper plate. The lower side wall of the upper plate is fixedly connected to the same lower plate by multiple elastic rods. A detection wheel is fixedly connected to the lower side wall of the lower plate. A laser generator and a laser receiver are respectively connected to the side walls of the upper plate and the lower plate on opposite sides.

[0009] Preferably, the follower assembly includes a follower seat slidably disposed inside the guide box. The follower seat is connected to the inner wall of the guide box via a slide rail mechanism. A bent rod is fixedly connected to the side wall of the follower seat away from the detection box. The side wall of the guide box has an opening that matches the bent rod. The upper end of the bent rod extends out of the guide box and is fixedly connected to an insert. Limiting electric push rods are connected to both the left and right sides of the drive seat. The moving end of the limiting electric push rod is fixedly connected to a pin that matches the insert. A pushing electric push rod is fixedly connected to the upper side wall of the follower seat. The moving end of the pushing electric push rod extends out of the guide box and is fixedly connected to a pushing plate. The upper side wall of the guide box has a moving opening that matches the pushing electric push rod.

[0010] Preferably, the analysis assembly includes multiple analysis cylinders fixedly connected to the upper inner wall of the detection box. Friction blocks are slidably disposed inside the analysis cylinders. A vertical rod is fixedly connected to the lower side wall of the friction blocks.

[0011] Preferably, the auxiliary component includes an auxiliary box, the inner wall of which is connected to a sliding seat via a spring, the upper side wall of the rotating plate is connected to a second electric push rod, and the moving end of the second electric push rod passes through the rotating plate and is connected to the auxiliary box, the lower side wall of the sliding seat is fixedly connected to a connecting rod, the connecting rod has an inverted L-shaped structure, the lower end of the connecting rod is fixedly connected to a connecting plate, the side wall of the connecting plate is fixedly connected to an auxiliary plate, the front and rear ends of the auxiliary plate are both inclined surfaces, and the side wall of the rotating plate is fixedly connected to a vision sensor.

[0014] Compared with existing technologies, the advantages of a horizontal alignment detection device for rotating bridges are as follows: 1. By setting up driving components, analysis components and detection components, mechanical contact detection is set on the pier after the construction of the rotating bridge is completed. Compared with setting detection components between two rotating bridges with a four-meter interval, the stable structural foundation of the pier can provide a fixed and accurate installation benchmark for the detection device. There is no need to lay out the detection structure between the four-meter-spacing bridges, avoiding the problems of inconvenience in operation and difficulty in fixing components caused by span installation. It can also effectively avoid the bending deformation of the detection rod across the four-meter span due to its own weight. The detection accuracy is guaranteed by both the installation benchmark and the detection structure itself.

[0015] 2. By using the auxiliary components, when using the contact detection device to detect the alignment of the rotating bridge, the impact of protrusions on the bridge surface on the detection accuracy can be avoided. This avoids problems such as deviation of the detection contact point and distortion of the benchmark judgment caused by unevenness of the local surface of the bridge. It ensures that the detection data can truly reflect the overall alignment status of the bridge, rather than false data interfered with by local surface defects. This makes the detection results more accurate and objective, and provides a reliable basis for judgment for subsequent alignment adjustment, reinforcement and other procedures in the closure construction.

[0016] 3. Through the set detection components, when the alignment is checked after the construction of the rotating bridge is completed, automatic multi-point detection can be achieved. This can get rid of the limitations of manual single-point detection, which not only greatly improves the detection efficiency and reduces the error caused by manual operation, but also forms a complete bridge alignment status data chain through multi-dimensional and multi-point detection data. It can accurately capture local offsets, tilts and other problems of the bridge, and avoid the omission of alignment deviation due to the one-sidedness of single-point detection. This allows the detection results to more comprehensively and accurately reflect the actual situation of the overall alignment of the bridge. Attached Figure Description

The side wall of the analysis cylinder 261 is fixedly connected to a pressure relief pipe 39. A pressure valve 40 is installed in the pressure relief pipe 39, which can restore multiple lifting plates 28 to their initial state.

[0022] The operating principle of this invention is explained as follows: After both rotating bridges have rotated to the upper end of the pier, the operator needs to install the mounting base 1 on the upper end of the pier. By measuring the distance, the mounting base 1 is placed in the middle of the two rotating bridges. Then, the operator controls the servo motor 8 via a remote control switch. The servo motor 8 drives the turntable 9, rotating rod 10, rotating plate 11, and other components to rotate to a set angle, aligning the rotating plate 11 with the detection component 15 and the rotating bridge. Then, the operator sends an electrical signal to the controller 2 via the remote control switch. Upon receiving the signal, the controller 2 first controls the first electric push rod 151 to operate. The first electric push rod 151, through a pressure sensor (not shown in the figure), drives the upper... The components, including plate 152, lower plate 16, and detection wheel 41, move downwards together, bringing the detection wheel 41 into contact with the surface of the left rotating bridge and maintaining a compressive force of 50N. Then, controller 2 controls the lead screw linear module 71 to work slowly. The lead screw linear module 71 drives the drive seat 72, servo motor 8, turntable 9, and detection component 15 to move, causing the detection wheel 41 to move along the surface of the rotating bridge. During the movement of the drive seat 72, the limit electric push rod 22 drives the pin 23 to insert into the insert 21. The drive seat 72 then drives the follower seat 201, the push electric push rod 24, and the push plate 25 to move together via the bent rod 202. During the operation of the lead screw linear module 71, when the push plate 25 moves below a lifting plate 28... The controller 2 will control the lead screw linear module 71 to pause operation according to the set program. The controller 2 will also control the pusher electric actuator 24 to move the pusher plate 25 by analyzing the distance detected by the laser generator 17 and laser receiver 18. The pusher plate 25 will move the lifting plate 28, friction block 262, U-shaped frame 29, and two trigger blocks 30 upwards to the set position, maintaining the position through the friction between the friction block 262 and the analyzer cylinder 261. When the pusher electric actuator 24 stops moving and retracts, the controller 2 will control the lead screw linear module 71 to continue operating. This process continues until all lifting plates 28 on that side have risen to the set position. Once the lead screw linear module 71 has moved to the set position, the controller 2 will... The controller 2 controls the servo motor 8 to operate, which in turn controls the detection component 15 to rotate 180 degrees. Simultaneously, the controller 2 controls the gear and toothed plate drive mechanism below the detection box 5 (the gear and toothed plate drive mechanism includes a drive motor connected to the lower side wall of the detection box 5, a gear connected to the output end of the drive motor, and a toothed plate meshing with the gear connected to the side wall of the mounting base 1; the drive motor controls the gear to rotate, and through the meshing of the gear and toothed plate, the detection box 5 can be moved). This causes the detection box 5 to move the detection component 15 to another rotating bridge surface. Then, the controller 2 controls the right limit electric push rod 22 to drive the pin 23 to insert into the right insert cylinder 21, and repeats the above detection process, causing the right lifting plate 28 to move multiple trigger plates 31 upwards together.When the trigger plate 31 is located in the area between the two trigger blocks 30, it will not contact the trigger blocks 30, indicating that the corresponding positions of the two rotating bridges are aligned (the symmetry of the rotating bridges allows for a 5mm error, and the distance between the two trigger blocks 30 is also 5mm). When the trigger plate 31 contacts the trigger blocks 30, it indicates that the corresponding positions of the two rotating bridges are misaligned. The trigger plate 31 is electrically connected to the external power supply, and the trigger blocks 30 are electrically connected to the controller 2, thereby sending an electrical signal to the controller 2 indicating that the rotating bridges are not aligned. The controller 2 will analyze the data transmitted by the laser receiver 18 and the laser generator 17, analyze the deviation value, and transmit this information through the wireless communication module. The rotating plate 11, while moving the detection component 15, analyzes the surface condition of the rotating bridge using the vision sensor 42. When a small protrusion (often dripping concrete or other impurities) is detected on the bridge surface, the controller 2 controls the second electric push rod 43 to move the auxiliary box 321 downwards. The auxiliary box 321, through the sliding seat 322, connecting rod 33, and connecting plate 34, moves the auxiliary plate 35 downwards, stopping it 1mm below the bridge surface. When the auxiliary plate 35 contacts the small protrusion, the inclined surface of the auxiliary plate 35, and the spring force between the sliding seat 322 and the auxiliary box 321, scrapes away the small protrusion.
