Description

Technical Field

[0001] This utility model belongs to the field of engineering testing technology, specifically relating to a bridge pier settlement detection device. Background Technology

[0002] Bridges are important transportation facilities, and their safety and stability are directly related to the safety of people's lives and property. As bridges bear vehicle loads for a long time, bridge piers may settle. In order to detect and deal with bridge settlement problems in a timely manner, it is necessary to conduct settlement detection on bridge piers. Current technology generally involves pre-embedding settlement observation points on the side walls of bridge piers, and then using elevation measuring devices such as level instruments to measure the top elevation of the settlement observation points. The settlement depth of the bridge pier is obtained by calculating the difference between the current measurement result and the initial measurement result.

[0003] Chinese patent CN222104705U discloses a soil settlement detection device for bridge and tunnel construction. This device includes a ranging unit comprising a laser rangefinder and a reflector. The laser rangefinder is connected to an angle display device, which includes a first angle disk. A second angle disk is rotatably mounted on the front of the first angle disk. Second pointers are rotatably mounted on both sides of the second angle disk. The second pointers are fixedly connected to the laser rangefinder via a rangefinder mounting bracket, with the laser rangefinder and the second pointer axes coinciding. This solution utilizes the characteristic that the laser rangefinder is always perpendicular to the ground due to gravity to read the readings of the first and second angle disks, thereby obtaining the building's tilt angle. The distance between the laser rangefinder and the reflector is measured using the laser rangefinder to detect the settlement depth.

[0004] The above solution uses the gravity of the laser rangefinder to keep it perpendicular to the ground. However, bridges are generally built in areas with crosswinds, and the laser rangefinder is prone to swaying under the influence of the wind. As a result, the above solution cannot be used to detect the settlement of bridge piers in areas with strong crosswinds, and its application scenarios are relatively limited. Utility Model Content

[0005] The present invention aims to provide a bridge pier settlement detection device to solve the problem that the above-mentioned solutions have limited application scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bridge pier settlement detection device includes an embedded part and an installation block. A first protractor is fixedly installed on one end wall of the embedded part. A fastening bolt is threaded onto the surface of the first protractor. The installation block is rotatably sleeved on the fastening bolt. A first level is fixedly installed on the top of the installation block. An indicator plate is fixedly installed on one side wall of the installation block parallel to the axis of the fastening bolt. A first indicator hole is opened on the side wall of the indicator plate. The indicator plate is connected to the first protractor by a locking assembly. An installation frame is fixedly installed on the side wall of the installation block away from the first protractor. A second protractor is fixedly installed at the bottom of the installation frame. A support block is rotatably installed inside the installation frame along the axis of the second protractor. A second level is fixedly installed on the side wall of the support block. A vertical rod is fixedly installed at the bottom of the support block. A second indicator hole is opened on the side wall of the vertical rod. A telescopic rod is rotatably connected to the bottom of the vertical rod. The end of the telescopic rod is rotatably connected to the installation block.

[0008] The principle and effects of this technical solution:

[0009] When pouring the concrete for the bridge pier, embedded parts are installed on the side wall of the bridge pier so that the first protractor is located outside the bridge pier. The mounting block is then fitted onto the fastening bolt, and the threaded section of the fastening bolt is inserted into the first protractor until the first protractor and the bolt caps of the fastening bolt are respectively attached to the two sides of the mounting block. During the initial measurement, the mounting block is first rotated to bring the first level to a horizontal position. Then, the indicator plate is fixed using the locking assembly, bringing the mounting block to a stationary state relative to the first protractor. The length of the telescopic rod is then changed to rotate the support block until the second level is horizontal. The reading aligned with the first and second indicator holes is recorded, and the initial elevation of the top of the support block is measured using a level instrument. After a certain period, the mounting block is rotated again and the telescopic rod is extended to bring the first and second levels horizontal again. The reading aligned with the first and second indicator holes is recorded a second time, and the difference between this reading and the initial reading is the tilt angle of the bridge pier under test in both directions. The elevation of the top of the support block is measured again using a level instrument, and the difference between this elevation and the initial elevation is the settlement depth of the bridge pier under test.

[0010] With the above settings, the indicator plate and the vertical rod can be kept stationary relative to the first and second protractors during the measurement process, avoiding the adverse effects of crosswinds on the settlement depth and tilt of the bridge piers, and solving the problem of the limited application scenarios of the above scheme.

[0011] In this invention, the side wall of the indicator plate has a through first screw hole, and the locking assembly includes a hand-tightening bolt threaded through the first screw hole. Through this arrangement, by rotating the hand-tightening bolt, the end of the hand-tightening bolt near the first protractor is pressed against the first protractor, thereby keeping the mounting block stationary relative to the first protractor.

[0012] In this invention, a mounting rod is fixedly installed at the bottom of the mounting block. The telescopic rod includes a bidirectional screw, with movable rods fitted at both ends of the bidirectional screw. The ends of the two movable rods, located away from each other, are rotatably connected to the bottom of the vertical rod and the bottom of the mounting rod, respectively. Through this arrangement, since the two movable rods cannot rotate along the axial direction of the bidirectional screw, they move closer or further apart as the bidirectional screw rotates, thus achieving the purpose of changing the length of the telescopic rod. Furthermore, after adjusting the telescopic rod to an appropriate length, its length remains constant, thereby keeping the vertical rod stationary relative to the second protractor.

[0013] In this invention, a dial is fixedly sleeved on the outer wall of the bidirectional screw. This design allows inspectors to easily rotate the bidirectional screw, improving the practicality of the device.

[0014] In this invention, the mounting bracket is U-shaped, and its open end is fixedly connected to the mounting block. A mounting frame is fixedly provided on the top of the second protractor, and the top of the mounting frame is fixedly connected to the bottom of the mounting bracket. This arrangement achieves the purpose of fixing the second protractor to the bottom of the mounting bracket.

[0015] In this invention, a limiting groove is provided circumferentially on the outer side wall of the first protractor away from the mounting block. A protrusion is fixedly provided at the end of the indicator plate outside the first protractor, and a limiting block that is slidably embedded in the limiting groove is fixedly provided on the side of the protrusion near the first protractor. This design prevents the friction between the hand-tightening bolt and the first protractor from decreasing due to bending of the indicator plate, ensuring that the mounting block remains stationary relative to the first protractor.

[0016] In this invention, two rotating shafts are symmetrically fixed to the two side walls of the support block, and the two rotating shafts are rotatably inserted into the mounting frame. This arrangement achieves the purpose of rotatably mounting the support block within the mounting frame along the axis of the second protractor.

[0017] In this invention, the surface of the first protractor is recessed with a second threaded hole extending to the embedded part, and the fastening bolt is threaded into the second threaded hole. This design allows for easy assembly and disassembly of the device, facilitating its storage. Attached Figure Description

[0030] In this embodiment, a limiting groove 111 is provided circumferentially on the outer side wall of the first protractor 11 away from the mounting block 20.
