Description

Technical Field

[0001] This utility model relates to the field of bridge pier deviation monitoring, and in particular to a Z-shaped bridge pier deviation monitoring device based on Beidou positioning technology. Background Technology

[0002] Existing detection technologies, such as prism-free total stations, manual visual inspection, and radar measurement, rely on placing radar measuring instruments or prism-free total stations under the bridge for detection or direct visual inspection. These methods require regular or irregular manual measurements, cannot monitor bridge deviation in real time for extended periods, and are prone to significant errors, resulting in substantial manpower consumption. While monitoring pier deviation by placing GPS positioning devices and displacement gauges on the piers allows for long-term real-time online monitoring, GPS positioning monitoring is costly, displacement gauge monitoring has low reliability, and it can only measure unidirectional deformation, making these methods imperfect for bridge monitoring. Currently, monitoring systems based on BeiDou satellite positioning are beginning to be applied to building monitoring. By installing BeiDou receivers on buildings and relying on BeiDou satellite positioning technology, real-time online monitoring of building settlement can be achieved.

[0003] Chinese utility model patent CN212676459U discloses a bridge pier deviation detection and installation device. The device is installed by installing expansion bolts on the side of the cap beam to fix a support steel pipe composed of L-shaped bends and straight pipes. The support steel pipe supports the antenna protection device. Two diagonal braces extend from the side of the support steel pipe and are fixed to the cap beam block by expansion bolts. Four diagonal cables are connected to the cap beam through lifting ring expansion bolts. The support steel pipe of the device is connected to the side of the cap beam by expansion bolts, so it must be installed using a bridge inspection vehicle or hanging basket. The construction process consumes a lot of manpower, greatly increases the installation cost, and brings inconvenience to the installation. In addition, the two diagonal braces of the device are connected to the support steel pipe by bending plates as diagonal brace connecting plates. The bending angle of the bending plate needs to be determined during production. It is necessary to analyze and calculate the connection position and length of the diagonal braces, which brings inconvenience to production and processing. Moreover, if there is a slight error in the size of the diagonal braces, it cannot be adjusted during installation, which may add extra force to the support steel pipe and is not conducive to the long-term use of the device. Furthermore, the lower cable of the device is located in the middle of the support steel pipe, which is an improper distribution and is not conducive to the support effect of the cable. Utility Model Content

[0004] In response to the shortcomings or deficiencies of traditional stop blocks, this utility model provides a Z-shaped bridge pier deviation monitoring device based on Beidou positioning technology, which solves the technical problems of difficult and inconvenient installation and improper force distribution in the existing technology.

[0005] The system includes a support steel pipe, a bracing device, and a stay cable device. The support steel pipe includes a bend and a sleeve assembly. One end of the sleeve assembly is connected to the bend, and the other end is connected to the antenna protection device. The sleeve assembly supports the antenna protection device. The bend is used to change the support direction of the sleeve assembly. The bend and the sleeve assembly are detachably connected via connecting lugs. The bend and the bend assembly are also detachably connected via connecting lugs. The bracing device includes a bracing connector, a bracing rod, and a bracing connecting plate. One end of the bracing rod is connected to the bracing connector, and the other end is connected to the bracing connecting plate. The bracing connector is located on the cap beam block of the pier, and the bracing connecting plate is located on the support steel pipe. The bracing device provides stable support for the support steel pipe. The stay cable device includes an eye expansion bolt, an eye bolt, and stay cables. The eye expansion bolt is located on the cap beam of the pier and connects to the stay cables. The stay cables are fixed to the support steel pipe via eye bolts. The stay cable device assists the bracing device in supporting the support steel pipe.

[0006] Furthermore, the bend consists of two identical L-shaped bends, and the sleeve assembly includes multiple sleeve assemblies of varying heights. Both ends of the bend and the sleeve assembly are provided with connecting lugs for splicing. The connecting lugs are provided with multiple connecting through holes spaced apart along their circumference. The bends are spliced ​​together by inserting bolts into the connecting lugs, and the bends are spliced ​​together by inserting bolts into the connecting lugs. The sleeve assemblies are spliced ​​together by inserting bolts into the connecting lugs.

[0007] Furthermore, there are two diagonal braces, one end of which is set on the diagonal brace connecting plate. The two diagonal braces form a V-shape and are fixed to the cap beam block of the pier through the diagonal brace connecting seat.

[0008] Furthermore, the diagonal brace connecting plate is a hinge, with through holes on both sides of the hinge. One side of the hinge is placed on the connecting ear plate of the support steel pipe and connected by bolts, while the other side is used for connecting the diagonal brace rod. The diagonal brace connecting seat is a base plate with through holes, and the base plate is connected to the cap beam block of the pier by expansion bolts.

[0009] Furthermore, there are four stay cables, arranged in groups of two. One end of the two stay cables is connected to the upper part of the support steel pipe by eye bolts, and the other end of the two stay cables is V-shaped and connected to the cap beam of the pier by eye expansion bolts. One end of the other two stay cables is connected to the lower part of the support steel pipe by eye bolts, and the other end of the other two stay cables is V-shaped and connected to eye expansion bolts set on the cap beam of the pier.

[0010] Preferably, the device of this application includes an installation cabinet and an antenna protection device.

[0011] The present invention has the following advantages: (1) The present invention provides a Z-shaped bridge pier deviation monitoring device based on Beidou positioning technology, including a support steel pipe, a bracing device and a cable device. The support steel pipe includes a bend and a sleeve assembly. The bend is used to change the support direction of the sleeve assembly. The sleeve assembly is used to support the antenna protection device. The bend is formed by connecting two L-shaped bends in a centrally symmetrical manner through expansion bolts on the connecting ear plate, so that the support steel pipe can be installed on the upper part of the cap beam. This solves the inconvenience caused by the need to install it through a hanging basket or bridge inspection vehicle, and reduces the bending moment damage to the cap beam caused by the installation on the side of the cap beam, greatly increasing the service life of the cap beam.

[0012] (2) This device uses a diagonal bracing device to support the support steel pipe. A hinge is used to connect the diagonal bracing rod and the support steel pipe as a diagonal bracing connecting plate. It can adapt to the connection ear plate of different heights of the support steel pipe. During the installation process, the connection position of the diagonal bracing connecting seat can be finely adjusted by the hinge, which can ensure that the support steel pipe will not generate internal force after installation, thus ensuring the service life of the device.

[0013] (3) This device provides auxiliary support for the support steel pipe through the inclined cable device. This device connects the lower inclined cable with the connecting lug of the bend pipe and sleeve assembly, ensuring the rationality of force distribution and better assisting the inclined bracing device in supporting the support steel pipe.
