Description

Technical Field

[0001] This invention relates to the field of monitoring instrument technology, specifically to a real-time monitoring instrument for the installation axis deviation of a small box girder. Background Technology

[0002] As a prefabricated structure, small box girders are easily constructed using mechanized and factory-based methods. Precast box girder technology, a mature construction method, accounts for over 70% of its application in highway and railway bridge projects and is widely accepted by designers and construction workers. Small box girders are frequently used in bridge engineering because they only require end diaphragms, resulting in a clean visual appearance under the bridge. Furthermore, their relatively low girder height offers advantages in areas with limited girder height and high aesthetic requirements. The structure also exhibits strong adaptability to widening variations and has a wide range of applications.

[0003] The box girder axis real-time monitoring instrument addresses the core need for structural deformation monitoring during bridge construction and maintenance. By integrating multiple types of sensors, such as laser rangefinders, tilt sensors, and fiber optic strain gauges, and combining them with BeiDou high-precision positioning and wireless transmission technology, it achieves millimeter-level real-time monitoring of parameters such as box girder axis offset, deflection, stress, and strain.

[0004] However, the existing real-time monitoring device for the installation axis deviation of small box girders has the following shortcomings:

[0005] 1) Traditional small box girder axis monitoring relies on manual periodic measurement or intermittent sampling by a single sensor, which has problems such as monitoring lag and discontinuous data. It is difficult to provide real-time feedback on deviation trends. The installation method usually lacks flexible adjustment mechanisms, relies on experience for positioning, and is easily affected by environmental vibration or installation errors, resulting in insufficient monitoring accuracy. The equipment protection measures are weak, and it is easily damaged when exposed to the outdoor environment for a long time. Moreover, maintenance requires complete disassembly, which is cumbersome.

[0006] 2) Traditional monitoring devices mostly use rigid fixing or threaded fastening methods, lacking multi-directional adjustment and self-locking functions. They are easily affected by construction vibrations, resulting in displacement and deviation of monitoring data. Their installation process relies on manual experience for positioning, lacks guiding and limiting structures, is inefficient and difficult to guarantee repeatability. When exposed to the outdoor environment for a long time, the equipment is prone to corrosion or wear due to the lack of buffer sealing design, requiring frequent shutdowns for maintenance.

[0007] 3) Traditional small box girder monitoring devices mostly use rigid fixing or threaded fastening methods, lacking a fine adjustment mechanism, which leads to the installation and positioning relying on manual experience, easily causing axial deviations that are difficult to correct.

[0008] Therefore, we propose a real-time monitoring instrument for the installation axis deviation of small box girders to solve the problems mentioned above. Summary of the Invention

[0043] The overall effect of Embodiment 2 is as follows: it improves the sealing performance and ease of operation of the equipment. The built-in gasket 6 in the side plate 5 can effectively prevent dust and water.

[0045] The overall effect of embodiment 3 is as follows: through the linkage design of the four corner limiting grooves 16 and the pinch plate 17, combined with the sliding connecting plate 18 with the pad 19 and the positioning groove 20 guide structure, multi-directional rapid positioning and stable locking are achieved.

It effectively solves the problems of cumbersome adjustment, easy loosening and positioning deviation of traditional mounting bases, and improves the equipment installation efficiency and long-term reliability.

[0046] The working principle of the entire device is as follows: First, lift the mounting frame 3 using the handle 304. Then, peel the protective plate 308 from the bottom of the adhesive 307. Align the limiting plate 301 and connecting rod 302 at the connection point between the two box girders and press firmly to make the fixing plate 303 drive the limiting plate 301 and connecting rod 302 to adhere to the side of the box girder. Next, lift the mounting base mechanism 4 and fix the mounting base body 401 inside the mounting frame 3 through the placement grooves A305 and B306. Then, firmly fix the mounting base body 401 through the mounting groove 403. Once both mounting base bodies 401 are completely fixed, pinch the pinch plate 17 and align the connecting plate 18 with the mounting groove 403, pressing it down so that the connecting plate 18... The pad 19 slides into the mounting body 401 through the mounting groove 403. Once the pad 19 is fixed inside the mounting body 401 through the positioning groove 20 and the pinch plate 17 is fixed inside the mounting body 401 through the limiting groove 16, grasp the handle 304 and pull it upwards to cause the limiting plate 301 and connecting rod 302 to detach from the surface of the box girder through the fixing plate 303, thus completing the first step of fixing the mounting mechanism 4. Then, pick up the first monitoring instrument 1 and the second monitoring instrument 2 and push the first upper sliding groove 402 of the pad 414 into the mounting body 401, so that the pad 414 slides completely into the mounting body 401 through the sliding groove 402. Then, pinch the top plate 407. Align the sliding plate 405 with the sliding groove 402 and push it inward. Push the top plate 407 through the pinch groove 408, causing the top plate 407 to drive the sliding plate 405 through the sliding groove 402 and completely slide it into the mounting base body 401 via the connecting block 406. Then, pinch the handle 412 to align the threaded rod 411 with the threaded groove 410 and rotate it, causing the threaded rod 411 to rotate into the fixing block 409 through the threaded groove 410. When the threaded rod 411 is completely rotated into the fixing block 409 through the threaded groove 410 and into the mounting base body 401 through the fixing groove 404, finally tighten the handle 412 and the threaded rod 411 through the groove 413. During use, the transmitter A108 and transmitter B2... 07 emits infrared rays, which are received by receivers A107 and B208. Monitoring is then completed via motherboards A104 and B204. During prolonged use, it operates via power supplies A102 and B202. When maintenance is required after extended use, first squeeze handle 15 and pull it backward. This causes slide rod 14 to slide backward through groove 9 inside protrusion 8. Simultaneously, slide rod 14, via baffle 12, drives latch 11 to slide into protrusion 8. Spring 13 then slides and retracts inside protrusion 8. Once latch 11 has completely slid out of housings A101 and B201 through groove 10, it is ready. Then, squeeze pull blocks A113 and B213 and pull backward.Cover plates A112 and B212 are rotated backward at the top of boxes A101 and B201 via hinges A111 and B211. During this rotation, cover plates A112 and B212 can drive support plate 7 and protrusion 8 to rotate backward together via side plate 5. At this time, side plate 5 drives washer 6 to slide off the surface of boxes A101 and B201. Finally, by removing bolts A105 and B110, main board A104 can be removed from support block A103. Remove receiver A107 from between mounting block A106 and retaining ring A109, and remove motherboard A104 and transmitter A108 from inside housing A101. Then, remove bolts C205 and D210 to remove motherboard B204 from support block B203 and receiver B208 from between mounting block B206 and retaining ring B209. Finally, remove motherboard B204 and transmitter B207 from inside housing B201 for maintenance.
