Description

Technical Field

[0001] The utility model belongs to the technical field of bridge monitoring equipment structure, and in particular relates to a deformation monitoring device for a main beam cantilever. Background Art

[0002] In modern construction projects, main beam cantilever structures are widely used in large structures such as bridges and high-rise buildings due to their advantages in spatial span and bearing capacity. However, deformation monitoring of the main beam cantilever during the construction process is crucial, as it is directly related to construction safety and the final quality of the structure.

[0003] Traditional monitoring devices mainly use three-axis angle sensors to sense changes in the fixed position to determine the deformation of the main beam cantilever. However, existing monitoring devices with three-axis angle sensors are usually fixed with screws, which are inconvenient to disassemble and install, and will leave threaded holes on the building surface, increasing subsequent maintenance costs. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a deformation monitoring device for a main beam cantilever, which can firmly fix the monitoring device at any rod position on the cantilever beam by means of a fixing method of a binding pin.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] The utility model includes a base, on which a three-axis angle sensor assembly is installed, a plurality of locking pins are threadedly connected to the base, the locking pins include a threaded section and a top pin section that are threadedly connected to the base, the top pin section faces the bottom surface of the base, a wide strap is also fixed to the base, and a buckle piece for fixing the wide strap is also fixed to the base.

[0007] Furthermore, a cylindrical seat is fixedly provided on the base, a round cover is threadedly connected to the cylindrical seat, a ball hole is jointly provided on the contact surfaces of the cylindrical seat and the round cover, a ball seat is rotatably provided in the ball hole, the three-axis angle sensor assembly is arranged in the ball seat, and the ball seat leaks out from the surface of the round cover.

[0008] Furthermore, a vertical guide column is fixedly provided directly above the ball seat.

[0009] Furthermore, a handle for easy rotation is fixedly provided at the top of the threaded section.

[0010] Furthermore, a solar panel is embedded on the ball seat, and the solar panel supplies power to the three-axis angle sensor assembly. The solar panel is arranged around the guide column.

[0011] The beneficial effects of the utility model are:

[0012] The utility model can quickly bind the monitoring device to any rod structure on the cantilever, and fix the encircling length of the wide binding strap by winding the binding strap into the buckle piece. At this time, the monitoring device can be firmly fixed on a surface by rotating four locking nails. The tilt angle of the base can be adjusted by the top placement of the four nail sections to keep the base as horizontal as possible. The wide binding strap can also be tightened so that the fixed monitoring device will not be displaced during the fixing period, which is convenient for monitoring by the three-axis angle sensor. During the monitoring process of the three-axis sensor, the data is transmitted to the data receiver, so that the angle change of the device at this position of the main beam cantilever can be monitored in real time to determine the deformation of the main beam cantilever. The device is firmly fixed and the monitoring data is accurate.

DETAILED DESCRIPTION

[0019] like Figures 1 to 3 As shown, the utility model discloses a deformation monitoring device for a main beam cantilever, comprising a base 1, on which a three-axis angle sensor assembly 2 is installed, on which four locking pins 3 are threadedly connected, and the locking pins 3 include a threaded section 31 and a top pin section 32 threadedly connected to the base 1, and a rotary handle 33 for easy rotation is fixed to the top of the threaded section 31, and the top pin section 32 faces the bottom surface of the base 1, and a wide strap 4 is also fixedly connected to the base 1, and a buckle piece 5 for fixing the wide strap 4 is also fixed to the base 1.

[0020] Through this structure, the monitoring device can be quickly bound to any rod structure on the cantilever, and the buckle piece 5 is wrapped around the strap to fix the wrapping length of the wide strap 4. At this time, the monitoring device can be firmly fixed on a surface by rotating the four locking nails 3. By placing the four nail sections on top, the inclination angle of the base 1 can be adjusted to keep the base 1 as horizontal as possible. The wide strap 4 can also be tightened so that the fixed monitoring device will not be displaced during the fixation period, which is convenient for monitoring by the three-axis angle sensor. During the monitoring process of the three-axis sensor, the data is transmitted to the data receiver, so that the angle change of the device at this position of the main beam cantilever can be monitored in real time to determine the deformation of the main beam cantilever. This device is firmly fixed and the monitoring data is accurate.

[0021] In a further solution, a cylindrical seat 6 is fixedly provided on the base 1, a round cover 7 is threadedly connected to the cylindrical seat 6, a ball hole is jointly provided on the contact surfaces of the cylindrical seat 6 and the round cover 7, a ball seat 8 is rotatably provided in the ball hole, the three-axis angle sensor assembly 2 is arranged in the ball seat 8, the ball seat 8 leaks out from the surface of the round cover 7, a vertical guide column 81 is fixedly provided directly above the ball seat 8, a solar panel 82 is embedded on the ball seat 8, the solar panel 82 supplies power to the three-axis angle sensor assembly 2, and the solar panel 82 is arranged around the guide column 81.

[0022] In this structure, by setting the cylindrical seat 6 and the round cover 7 to clamp the ball seat 8, the angle position of the ball seat 8 can be adjusted after the base 1 is fixed. Through the guide column 81, it can be easily judged whether the ball seat 8 is aligned. The ball seat 8 can also be aligned by holding the guide column 81 to provide a more correct placement angle for the three-axis angle sensor, providing the most accurate monitoring environment. Solar panels 82 are set around the guide columns 81 of the ball seat 8 to power the three-axis angle sensor and ensure the long-term operation of this device.
