[0002] Bridge construction is a complex and difficult task in construction engineering, involving the use of a variety of technical means, equipment and materials. Bridges are usually used to cross obstacles such as rivers, canyons, railways, and roads, so their design and construction need to consider the safety, durability and environmental adaptability of the structure; the steps and techniques of bridge construction include design, foundation construction, pier construction, bridge deck construction, etc. The following is the general process and related technologies of bridge construction.

[0003] During the construction of cast-in-place bridges, asymmetric multi-span cantilever structures often face problems such as structural deformation and uneven stress distribution due to their unique span and uneven stress characteristics. Traditional quality inspection methods usually focus on inspections after the completion of bridge construction. However, during the construction of multi-span cantilever structures, how to monitor their quality in real time and adjust the construction plan in time is still a technical problem. Existing quality inspection devices are difficult to adapt to the dynamic monitoring and real-time feedback of this special structure, resulting in the inability to effectively prevent quality risks that may occur during the construction process of bridges. In addition, traditional inspection methods often have problems such as long inspection cycle, low precision, and complex operation, which are difficult to meet the high requirements of modern bridge construction for quality and safety. Therefore, the present invention proposes a new type of asymmetric multi-span cantilever cast-in-place quality inspection mechanism, which aims to improve inspection efficiency, accuracy and safety.

[0029] The beneficial effects of the present invention are: 1. By setting a moving device, the positions of the first detection device and the second detection device can be adjusted, which is convenient for rapid adjustment according to needs. By starting the mobile motor, the transmission rod can be driven to rotate, thereby driving the rotation of the mobile gear. The two mobile gears can drive the connecting frame to move on the guide rail, so that the bridge detection position after construction can be appropriately adjusted. In order to drive the mobile shell to move left and right, the lead screw in the mobile component is driven by the motor to rotate and then drive the slider to move on the mobile frame, so that the mobile shell can be driven to move left and right to complete the position adjustment.

They are used when detection is needed and are located above when not detected, which does not affect the construction, so that detection can be carried out quickly, which solves the problems of long detection cycle, low precision, complex operation and other problems in traditional detection methods in existing bridge construction, and it is difficult to meet the high requirements of quality and safety in modern bridge construction.

[0030] 2. By setting up the first detection device, the bridge can be detected in all directions. The magnetic ring on the driving rod can be magnetically connected with the corresponding driving gear ring after being energized. The rotation of the driving rod can drive the driving gear ring to rotate, thereby driving the deflection plate to selectively rotate in combination or individually, changing the detection position, so that cantilever cast-in-place construction with different spans and asymmetrical arrangements can be used to ensure the accuracy and reliability of the detection results, and solves the technical problems that traditional detection methods in existing bridge construction often have long detection cycles, low precision, and complex operations, and are difficult to meet the high requirements of quality and safety in modern bridge construction.

[0031] 3. By setting up the second detection device, the sensor in the second detection sensor group can be fixed at the key stress position of the hanging basket and detected. The second detection sensor group is fixed by releasing the lifting rope. After manually rotating the adjusting screw rod, the pushing frame is driven to move, so that the pushing plate can be pushed to move. After the locking block is pushed up, the locking block leaves the groove of the threaded sleeve. At the same time, after the transmission gear ring is engaged with the deflection gear disc, the rotation of the clamping screw rod can drive the deflection gear disc to rotate through the transmission gear ring. After the deflection handle is pulled by the pulling rod, the deflection block is driven to deflect and converted from a parallel state to a vertical state, so that one side of the electromagnet can fit the plate shape of the hanging basket. Through the rotation of the clamping screw rod, the clamping block can be driven to move relatively, so that the cylindrical wire rope or pillar can be fixed, so as to facilitate the flexible use of the sensors of the second detection sensor group, solve the problems of long detection cycle, low precision, complex operation and so on in the existing bridge construction, and it is difficult to meet the high requirements of quality and safety of modern bridge construction.

When it is necessary to detect the hanging basket 1 or the cast bridge, the adjustment motor 55 is started to drive the drive rod 56 to rotate, and the drive rod 56 drives the corresponding magnetic ring to rotate. When it is necessary to drive the corresponding sensor in the first detection sensor group 57 to rotate, the corresponding magnetic ring is energized and magnetically connected to the drive gear ring 54. The rotation of the magnetic ring drives the drive gear ring 54 to rotate, and the drive gear ring 54 drives the transmission gear 53 to rotate. The transmission gear 53 drives the gear ring on the rotating sleeve 51 to rotate, and the rotating sleeve 51 drives the deflection plate 52 to rotate, so that the sensors of the first detection sensor group 57 can be driven to rotate, and the positions of the sensors in the first detection sensor group 57 are adjusted, so that the key nodes can be detected. The lifting roller 61 in the lifting shell 6 is rotated under the start of the lifting motor 62. The lifting roller 61 is transmitted through the synchronous belt and the synchronous wheel, so that one lifting motor 62 can drive the two lifting rollers 61 to rotate synchronously, so that after the lifting rope is released to a suitable distance, the corresponding sensor in the second detection sensor group 63 is moved to a suitable position to be detected, and the clamping slider 71 is located on both sides of the steel cable or cylindrical pillar, and the clamping motor 75 is controlled to start. The clamping motor 75 can drive the clamping slider 71 on the fixed slide 7 to move relatively. After the clamping slider 71 drives the clamping block 73 to move relatively, the clamping block 73 clamps the steel cable or circular pillar on the hanging basket 1 to complete the fixation of the sensor; When it is necessary to fix the sensors in the second detection sensor group 63 on the plate-shaped frame of the hanging basket 1, the adjusting screw rod 83 is manually rotated, and the adjusting screw rod 83 can drive the pushing frame to move, thereby pushing the pushing plate 88 to move. After the locking block 86 is pushed up, the locking block 86 leaves the groove of the threaded sleeve 76, and the limit of the threaded sleeve 76 is released. The rotation of the clamping screw rod 74 drives the threaded sleeve 76 to rotate synchronously, and cannot drive the clamping slider 71 to move. At the same time, after the transmission gear ring 85 is engaged with the deflection gear disc 8, the rotation of the clamping screw rod 74 can drive the deflection gear disc 8 to rotate through the transmission gear ring 85, and then the deflection handle 82 is pulled by the pulling rod 81 to drive the deflection block 72 to deflect, and the parallel state is converted into a vertical state, so that one side of the electromagnet can fit the plate shape of the hanging basket 1, and the sensors in the second detection sensor group 63 are fixed. The four sensors in the second detection sensor group 63 are distributed in different positions to complete the detection of the quality of the cast-in-place bridge.
