Description

Technical Field

[0001] This utility model relates to the field of alignment monitoring technology, specifically to an alignment monitoring system for cast-in-place curved beams. Background Technology

[0002] During bridge construction, it is necessary to monitor the alignment of curved beams to ensure their proper shape.

[0003] Among them, announcement number CN209841040U discloses a device for monitoring the arch rib alignment of a cross-river arch bridge. A sensor base is welded to the central axis of the monitoring point on the arch rib of the cross-river arch bridge, and a water tank is installed on the arch crown of the arch rib. All liquid level and pressure transmitter assemblies are connected in series via a connecting pipe. The outlet of the water tank is connected to a tee connector on one of the connecting pipes via a water guide pipe, filling the water tank until both the connecting pipe and the water guide pipe are full. All liquid level and pressure transmitter assemblies are installed on the sensor base at each monitoring point. The readings of each liquid level and pressure transmitter assembly are read at any time according to the required construction conditions, thereby realizing the monitoring of the arch rib alignment of the cross-river arch bridge. However, this technical solution still has shortcomings:

[0004] In this technical solution, multiple level and pressure transmitter components are connected to the sensor base welded to the bridge by bolts and threaded fastening. Therefore, after use, multiple threaded rods need to be turned one by one to separate the threaded rods from the sensor base in order to disassemble the level and pressure transmitter components. The operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0005] In view of the problems existing in the current cast-in-place curved beam alignment monitoring system, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a cast-in-place curved beam alignment monitoring system, which solves the problem that in the existing technology, multiple liquid level and pressure transmitter components in the arch rib alignment monitoring device for cross-river arch bridges are all connected to the sensor base welded to the bridge by bolts and threaded locks. Therefore, after use, it is necessary to unscrew multiple threaded rods one by one to separate the threaded rods from the sensor base in order to disassemble the liquid level and pressure transmitter components. This operation is cumbersome, time-consuming and labor-intensive.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cast-in-place curved beam alignment monitoring system includes a curved beam body and a liquid level and pressure transmitter assembly. Multiple mounting brackets are fixedly welded to the front side of the curved beam body. Multiple liquid level and pressure transmitter assemblies are abutted against each other on the side of the mounting brackets away from the curved beam body. A water tank is fixedly installed on the upper surface of the middle part of the curved beam body. The water tank is connected to the liquid level and pressure transmitter assembly in the middle part through a first connecting pipe. Multiple liquid level and pressure transmitter assemblies are connected to each other through a second connecting pipe.

[0009] Each of the mounting brackets has a socket at one end near the liquid level and pressure transmitter assembly, and each of the liquid level and pressure transmitter assemblies has a fixed rod on one side near the mounting bracket. Each of the rods is inserted into the corresponding socket. The end of the rod away from the liquid level and pressure transmitter assembly is provided with a limiting mechanism to restrict the movement of the rod relative to the mounting bracket.

[0010] Preferably, the limiting mechanism includes a limiting rod and a slider. A groove is provided at the end of the insertion rod away from the liquid level and pressure transmitter assembly. A slide rod is fixedly installed inside the groove. The slider is movably sleeved on the wall of the slide rod. The limiting rod is fixedly installed on the side of the slider away from the liquid level and pressure transmitter assembly. The end of the limiting rod near the insertion rod abuts against the side of the mounting bracket away from the liquid level and pressure transmitter assembly.

[0011] Preferably, a spring is movably sleeved on the wall of the slide rod, and the two ends of the spring are fixedly connected to the upper surface of the corresponding slider and the inner wall of the slide groove, respectively.

[0012] Preferably, both sides of the slider abut against the inner wall of the groove.

[0013] Preferably, the longitudinal section of the insertion rod, the limiting rod, and the insertion hole are all rectangular.

[0014] Preferably, a rubber pad is fixedly provided on the outer wall of the insertion rod.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model, by passing the limiting rod through the insertion hole and inserting the insertion rod into the insertion hole, under the action of the spring force, the slider drives the limiting rod to move downward, so that the limiting rod and the insertion rod are misaligned, so that the limiting rod limits the liquid level pressure transmitter assembly and the mounting bracket, and the linearity monitoring of the curved beam body can be carried out.

[0017] 2. This utility model allows for the easy and time-saving disassembly of the liquid level and pressure transmitter assembly by pushing the limiting rod upward after the monitoring work is completed, so that the limiting rod and the insertion rod are on the same horizontal line.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a system for monitoring the alignment of cast-in-place curved beams.

[0026] Reference Figure 1-3 A cast-in-place curved beam alignment monitoring system includes a curved beam body 1 and a liquid level and pressure transmitter assembly 3. Multiple mounting brackets 6 are fixedly welded to the front side of the curved beam body 1. Multiple liquid level and pressure transmitter assemblies 3 are abutted against each other on the side of the mounting brackets 6 away from the curved beam body 1. A water tank 2 is fixedly installed on the upper surface of the middle part of the curved beam body 1. The water tank 2 is connected to the liquid level and pressure transmitter assembly 3 in the middle part through a first connecting pipe 5. Multiple liquid level and pressure transmitter assemblies 3 are connected to each other through a second connecting pipe 4.

[0027] Multiple mounting brackets 6 have insertion holes at one end near the liquid level and pressure transmitter assembly 3, and multiple liquid level and pressure transmitter assemblies 3 have insertion rods 7 fixedly installed on one side near the mounting brackets 6. Multiple insertion rods 7 are inserted into the corresponding insertion holes, and rubber pads are fixedly installed on the outer wall of the insertion rods 7 to make the insertion of the insertion rods 7 into the insertion holes more secure.

[0028] Reference Figure 1-3 The end of the insertion rod 7 away from the liquid level and pressure transmitter assembly 3 is provided with a limiting mechanism to restrict the movement of the insertion rod 7 relative to the mounting bracket 6. The limiting mechanism includes a limiting rod 8 and a slider 10. A sliding groove is opened at the end of the insertion rod 7 away from the liquid level and pressure transmitter assembly 3. A sliding rod 9 is fixedly installed inside the sliding groove. The slider 10 is movably sleeved on the rod wall of the sliding rod 9. The limiting rod 8 is fixedly installed on the side of the slider 10 away from the liquid level and pressure transmitter assembly 3. The end of the limiting rod 8 near the insertion rod 7 abuts against the side of the mounting bracket 6 away from the liquid level and pressure transmitter assembly 3.

[0029] Reference Figure 1-3 A spring 11 is movably sleeved on the wall of the slide rod 9. The two ends of the spring 11 are fixedly connected to the upper surface of the corresponding slider 10 and the inner wall of the slide groove, respectively, so that the slider 10 can drive the limiting rod 8 to move and be misaligned with the insertion rod 7. Both sides of the slider 10 are in contact with the inner wall of the slide groove, so that the slider 10 cannot rotate, that is, it can slide stably. The longitudinal section of the insertion rod 7, the limiting rod 8 and the insertion hole are all rectangular, so that the insertion rod 7 and the limiting rod 8 cannot rotate relative to the insertion hole, that is, it can limit the liquid level and pressure transmitter assembly 3 in the circumferential direction.

[0030] In this invention, during use, the limiting rod 8 is passed through the insertion hole, and the insertion rod 7 is inserted into the insertion hole. Under the elastic force of the spring 11, the slider 10 drives the limiting rod 8 to move downward, causing the limiting rod 8 and the insertion rod 7 to be misaligned. This allows the limiting rod 8 to limit the liquid level and pressure transmitter assembly 3 and the mounting bracket 6, enabling the monitoring of the curve beam body 1's alignment. After the monitoring is completed, the limiting rod 8 is pushed upward, so that the limiting rod 8 and the insertion rod 7 are on the same horizontal line. The insertion rod 7 and the limiting rod 8 can then be pulled out of the insertion hole, thus achieving time-saving and labor-saving disassembly of the liquid level and pressure transmitter assembly 3, greatly improving work efficiency.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
