[0002] The roadbed is the foundation of the track or road surface. It is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads, while transferring and diffusing the load deep into the foundation.

[0003] At present, settlement observation plates are generally used to monitor the settlement of roadbed. However, due to the light texture of the settlement observation plates themselves, the fit between the settlement observation plates and the roadbed is not strong. When the roadbed sinks, the sinking amplitude of the settlement observation plates is not obvious, so the settlement information cannot be accurately collected. In view of this, the utility model is proposed to provide a structure displacement measurement system to solve the above problem. Utility Model Content

The earth pit is equivalent to the inner base layer of the measured roadbed. When the inner base layer sinks, the displacement monitoring plate also sinks. The descent of the displacement monitoring plate is fed back to the lifting column. People can judge whether the roadbed has displacement and settlement by observing the position of the monitoring scale line, so that people can accurately collect displacement and settlement information.

A pit of a certain depth is dug at the roadbed monitoring point. After the pit is dug, the mounting shell 1 is moved to the top of the pit and supported on the roadbed surface by the support frame 2. The displacement monitoring plate 3 is buried in the pit so that the bottom of the displacement monitoring plate 3 fits with the bottom of the pit. A mounting track 7 is fixedly connected to the outer wall of one side of the mounting shell 1, and a support rod 8 is slidably installed on the inner wall of the mounting track 7. The top of the support rod 8 is fixed A connecting seat 9 is connected, and both ends of the connecting seat 9 are fixedly connected to symmetrically arranged first mounting frames 10, and the bottom ends of the two first mounting frames 10 are hinged with lifting rods 11, and a pressure plate 20 is slidably installed on the inner wall of the mounting shell 1, and the outer wall of the top of the pressure plate 20 is fixedly connected to a symmetrically arranged second mounting frame 22, and the bottom ends of the two lifting rods 11 are respectively hinged on the two second mounting frames 22, and the outer wall of one side of the support rod 8 is fixedly connected to the first connecting frame 14, and the first connecting frame 14 is hinged with a guide rod 15, and a nut seat 18 is slidably installed on the outer wall of one side of the mounting shell 1, and the outer wall of one side of the nut seat 18 is fixedly connected to the second connecting frame 19, and the bottom of the guide rod 15 The end is hinged on the second connecting frame 19, the outer wall of the bottom of the mounting track 7 is rotatably installed with a screw rod 16, and the nut seat 18 is screwed on the screw rod 16. A driving motor 17 is fixedly installed on the outer wall of one side of the mounting shell 1, and the output shaft of the driving motor 17 is connected to the bottom end of the screw rod 16. When the bottom of the displacement monitoring plate 3 is in contact with the bottom of the pit, the driving motor 17 is started to drive the screw rod 16 to rotate, and the screw rod 16 drives the nut seat 18 to move downward, and the nut seat 18 drives the second connecting frame 19 to move downward. The second connecting frame 19 cooperates with the first connecting frame 14 to change the inclination angle of the guide rod 15. When the inclination angle of the guide rod 15 changes When the mounting rail 7 is changed, it can drive the support rod 8 to move laterally, so that the support rod 8 drives the connecting seat 9 to move laterally, and the connecting seat 9 drives the two first mounting frames 10 to move laterally. The two second mounting frames 22 are arranged in cooperation with each other, so that the inclination angle of the two lifting rods 11 changes. When the inclination angle of the two lifting rods 11 changes, the pressure plate 20 can be driven to move downward. When the pressure plate 20 moves down to contact the top of the displacement monitoring plate 3, the pressure plate 20 applies pressure to the displacement monitoring plate 3, thereby increasing the contact strength between the displacement monitoring plate 3 and the earth pit, which is equivalent to the inner base layer of the roadbed to be measured.

[0026] In a specific embodiment, the bottom end of the lifting column 4 extends to the bottom of the support frame 2, the displacement monitoring plate 3 is located directly below the support frame 2, the pressure plate 20 is located directly above the displacement monitoring plate 3, an opening is opened in the middle of the pressure plate 20, and the lifting column 4 is slidably set on the inner wall of the opening, and a monitoring scale line 12 is set on one side of the lifting column 4. When the inner base layer sinks, the displacement monitoring plate 3 also sinks, and the descent of the displacement monitoring plate 3 is fed back to the lifting column 4. People judge whether the roadbed has displacement and settlement by observing the position of the monitoring scale line 12. A symmetrically arranged movable groove 13 is opened on one side of the top of the mounting shell 1, and the two lifting rods 11 are in contact with the inner walls of the two movable grooves 13 respectively.

[0027] Furthermore, a fixing seat 5 is fixedly connected to the outer wall on the right side of the top of the mounting shell 1, a through hole is opened in the middle of the fixing seat 5, and a limiting screw 6 is arranged in the through hole, a limiting slot 21 is opened on one side of the lifting column 4, and an internal thread is opened on the inner wall of the limiting slot 21, and the limiting screw 6 is adapted to the limiting slot 21. When it is necessary to move the device above the pit, the limiting screw 6 is screwed into the limiting slot 21 to prevent the lifting column 4 from sliding down during the movement. When the device is moved above the pit and the support frame 2 is supported on the roadbed surface, the limiting screw 6 is unscrewed from the limiting slot 21, so that the lifting column 4 can drive the displacement monitoring plate 3 to move downward.

[0028] The implementation principle of a structure displacement measurement system of this embodiment is as follows:

[0029] When in use, a pit of a certain depth is dug at the roadbed monitoring point. After the pit is dug, the installation shell 1 is moved to the top of the pit and supported on the roadbed surface by the support frame 2. The displacement monitoring plate 3 is buried in the pit so that the bottom of the displacement monitoring plate 3 fits with the bottom of the pit. Then the drive motor 17 is started to drive the screw rod 16 to rotate, and the screw rod 16 drives the nut seat 18 to move downward, and the nut seat 18 drives the second connecting frame 19 to move downward. The second connecting frame 19 cooperates with the first connecting frame 14 to change the inclination angle of the guide rod 15. When the inclination angle of the guide rod 15 changes, the installation track 7 that is provided in cooperation can drive the support rod 8 to move horizontally, so that the support rod 8 drives the connecting seat 9 to move horizontally. The connecting seat 9 drives the two first mounting frames 10 to move horizontally, and the two second mounting frames 22 arranged in cooperation change the inclination angles of the two lifting rods 11. When the inclination angles of the two lifting rods 11 change, the pressure plate 20 can be driven to move downward. When the pressure plate 20 moves down to contact the top of the displacement monitoring plate 3, the pressure plate 20 applies pressure to the displacement monitoring plate 3, thereby increasing the contact strength between the displacement monitoring plate 3 and the pit. The pit is equivalent to the inner base layer of the measured roadbed. When the inner base layer sinks, the displacement monitoring plate 3 also sinks. The descent of the displacement monitoring plate 3 is fed back to the lifting column 4. People judge whether the roadbed has displacement and settlement by observing the position of the monitoring scale line 12.
