Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a foundation settlement detection device. Background Art

[0002] Foundation settlement refers to the settlement of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, will cause the building to tilt, crack and even be unable to be used normally. Therefore, during the construction process and after the completion of the building, it is necessary to detect the settlement value of the foundation to prevent the building from being unable to be used normally due to excessive settlement value.

[0003] The existing foundation settlement detection methods often use precise engineering level instruments and accurately scaled leveling rods for detection. Usually, during the detection, it can be detected that there is settlement at a certain position, but the specific settlement value is not convenient to read out. Moreover, when the foundation settles, there will be an inclination, and the inclination data is also not convenient to specifically read out. After the settlement position is detected, in order to facilitate data comparison, it is necessary to record each settlement data. In the record, the orientation is also a very important data, but it is not convenient to measure. In view of the above problems, we propose a foundation settlement detection device.

There are two pulleys 19, which are respectively coaxially and fixedly sleeved on the rotating rod 13 and the connecting shaft rod 18. The connecting belt 20 connects the two pulleys 19. When the detection plate 12 moves downward, it drives the rack 14 to move downward, and then drives the gear 15 to rotate, driving the rotating rod 13 to rotate, and drives the longitudinal inclination detection mechanism to rotate through the pulley mechanism 16, providing a power source.

[0038] The longitudinal inclination detection mechanism of the present invention includes a U-shaped frame 21 and an angle dial mechanism 22. The U-shaped frame 21 is fixedly connected to the rotating collar 10. The U-shaped frame 21 is rotatably connected to the connecting shaft rod 18. The angle dial mechanism 22 is fixedly connected to the U-shaped frame 21. The pointer rotating shaft of the angle dial mechanism 22 is fixedly connected to the connecting shaft rod 18. The transverse inclination detection mechanism 4 includes a support column 23 and an angle dial 24. The connecting shaft 6 is rotatably arranged at the upper end of the fixed support column 8. The support column 23 is coaxially sleeved on the surface of the connecting shaft 6 and is rotatably connected to the connecting shaft 6. The angle dial 24 is connected to the upper end surface of the support column 23. The angle indicating needle of the angle dial 24 is fixedly connected to the connecting shaft 6. The intermittent lifting mechanism 7 includes a lifting mechanism 25 and a connecting mechanism 26. The lifting mechanism 25 is connected to the upper end of the base collar 9 and is arranged on one side of the fixed support column 8. One end of the connecting mechanism 26 extends into the support column 23, and the other end extends into the fixed support column 8. The lifting mechanism 25 includes an arc plate 27, a support plate 28, a support collar plate 29, a fixed support plate 30, and an arc lifting plate 31. The arc plate 27 is fixedly connected to the base collar 9 and is arranged on one side of the fixed support column 8. The support plate 28 is fixedly connected to the arc plate 27 and extends towards the central axis direction of the fixed support column 8. The support collar plate 29 is fixedly connected to the support plate 28 and is coaxially and movably sleeved on the connecting shaft 6. The fixed support plate 30 is fixedly connected to the support plate 28. The arc lifting plate 31 is fixedly connected to the fixed support plate 30. The upper end surface of the arc lifting plate 31 is arc-shaped. The connecting mechanism 26 is arranged in a circumferential array of four with the center position of the fixed support column 8 as the reference. The connecting mechanism 26 includes a connecting rod body 32, a spring 33, and a cylindrical rod 34. There is a cylindrical groove 35 on the support column 23. The upper end of the connecting rod body 32 is arranged in the cylindrical groove 35 and is slidably connected to the support column 23 up and down. The lower end extends into the fixed support column 8. The spring 33 is arranged in the cylindrical groove 35 and at the upper end of the connecting rod body 32. The cylindrical rod 34 is fixedly connected to the side end of the connecting rod body 32. The cylindrical rod 34 is arranged above the lowest point and below the highest point of the upper end surface of the arc lifting plate 31. When the rotating support cross plate 11 is rotated, it drives the rotating collar 10 and the base collar 9 to rotate. When the base collar 9 rotates, it drives the arc plate 27 to rotate, and then drives the support plate 28 to rotate, and then drives the fixed support plate 30 to rotate, and then drives the arc lifting plate 31 to rotate. The arc lifting plate 31 contacts the cylindrical rod 34, and the cylindrical rod 34 moves upward, driving the connecting rod body 32 to move upward. Thus, the connecting rod body 32 rises from the fixed support column 8 to the upper end of the support plate 28. Before the connecting rod body 32 touches the side end of the support plate 28, the connecting rod body 32 has been lifted to the upper end of the support plate 28 by the arc lifting plate 31, avoiding the connecting rod body 32 from hindering the rotation of the support plate 28. At the same time, the other two groups of connecting rod bodies 32 extend into the fixed support column 8 under the pressure of the spring 33, restricting the rotation of the angle dial 24 and ensuring its stability.The azimuth position that can be clearly detected is indicated by the angle indicator needle rotating through the angle scale two 24.

[0039] Principle of the present invention:

[0040] During use, the fixed support column 8 is placed in a horizontal position and fixed. The 0 scale on the detection plate 12 is flush with the lower end surface of the support cross plate 11. Driven by the tension spring 38, the extension plate 37 and the detection plate 12 tend to move downward. When there is settlement, the detection plate 12 moves downward, and the settlement value is determined by observing the scale line on the detection plate 12.

[0041] When the detection plate 12 moves downward, it drives the rack 14 to move downward, thereby driving the gear 15 to rotate, driving the rotating rod 13 to rotate, and driving the pointer rotating shaft in the angle scale mechanism one 22 to rotate through the pulley mechanism 16. The reading on the angle scale mechanism one 22 pointed to by the pointer rotating shaft is read, so as to calculate the settlement inclination.

[0042] Rotate the support cross plate 11 to drive the displacement type height detection mechanism 2 and the longitudinal inclination detection mechanism 3 to rotate, facilitating the detection of the surrounding inclination and settlement.

[0043] When the support cross plate 11 is rotated, it drives the rotating collar 10 and the base collar 9 to rotate. When the base collar 9 rotates, it drives the arc plate 27 to rotate, thereby driving the support plate 28 to rotate, further driving the fixed support plate 30 to rotate, and further driving the arc jacking plate 31 to rotate. The arc jacking plate 31 contacts the columnar rod 34, and the columnar rod 34 moves upward, driving the connecting rod body 32 to move upward, so that the connecting rod body 32 rises from the fixed support column 8 to the upper end of the support plate 28, avoiding the connecting rod body 32 from hindering the rotation of the support plate 28. At the same time, the other two groups of connecting rod bodies 32 extend into the fixed support column 8 under the pressure of the spring 33, restricting the rotation of the angle scale two 24 and ensuring its stability. The azimuth position that can be clearly detected is indicated by the angle indicator needle rotating through the angle scale two 24.

[0044] The present invention and its embodiments have been described above. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
