For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0020] The utility model is described in detail below in conjunction with the accompanying drawings.
[0021] A rail transit deep foundation pit monitoring device, such as Figures 1 to 3 As shown, it includes a base 1, a fixing plate 2 is fixedly installed on the left and right sides of the upper end of the base 1, and an adjusting component 3 is commonly arranged on the opposite surfaces of the two fixing plates 2. A supporting plate 4 is fixedly installed on the upper end of the adjusting component 3, and a first positioning bolt 5 is movably inserted and connected to the front end of the supporting plate 4, and an adjusting component 6 is arranged on the upper end of the supporting plate 4. A connecting rod 7 is movably inserted and connected to the upper end of the supporting plate 4, and a transmission line 8 is fixedly inserted and connected to the upper end of the connecting rod 7. An inclinometer 9 is fixedly installed on the top of the transmission line 8, and a sensor 10 is fixedly installed on the bottom end of the transmission line 8. A circular groove 11 is opened on the upper end of the base 1, and the axial center lines of the connecting rod 7 and the circular groove 11 coincide with each other. The supporting plate 4 limits the connecting rod 7 to prevent the connecting rod 7 and the sensor 10 from being offset, thereby improving stability, preventing the sensor 10 from colliding with the foundation pit wall during descent, and preventing equipment damage.
[0022] Four supporting legs 12 are fixedly mounted on the lower end of the base 1 , and the supporting legs 12 provide support for the base 1 .
[0023] like Figure 2 As shown, the adjustment component 3 includes a screw rod 31, a servo motor 32 is fixedly installed at the lower end of the screw rod 31, an adjustment plate 33 is threadedly connected to the outer surface of the screw rod 31, and a limit rod 34 is movably inserted and connected to the right side of the upper end of the adjustment plate 33. The servo motor 32 is fixedly connected to the lower end of the base 1, and the support plate 4 is fixedly connected to the upper end of the adjustment plate 33. The servo motor 32 drives the screw rod 31 to rotate, thereby driving the adjustment plate 33 to move downward along the screw rod 31. The limit rod 34 is provided to limit the adjustment plate 33 to prevent the adjustment plate 33 from positional displacement. When the sensor 10 and the connecting rod 7 are driven downward by the adjustment plate 33 to pass through the foundation pit on the ground below the circular groove 11, the connecting rod 7 is loosened by rotating the first positioning bolt 5 and the second positioning bolt 63.
[0024] like Figure 3As shown, the adjustment assembly 6 includes a cylinder 61, two cylinders 61 are provided, and an adjustment plate 62 is fixedly installed at the output end of the two cylinders 61, and a second positioning bolt 63 is movably inserted and connected to the front end of the adjustment plate 62. The cylinder 61 is fixedly connected to the upper end of the support plate 4. When the cylinder 61 is started to push the adjustment plate 62 to move upward, the connecting rod 7 is driven to move upward.
[0025] Working principle: The servo motor 32 drives the screw rod 31 to rotate, thereby driving the adjustment plate 33 to move downward along the screw rod 31. The limit rod 34 is set to limit the adjustment plate 33 to prevent the adjustment plate 33 from position deviation. The sensor 10 and the connecting rod 7 are driven downward by the adjustment plate 33 to pass through the foundation pit on the ground below the circular groove 11. The connecting rod 7 is loosened by rotating the first positioning bolt 5 and the second positioning bolt 63. At this time, when the connecting rod 7 is under weight and falls downward, it is convenient to further lower the sensor 10. The support plate 4 acts as a limit on the connecting rod 7 to prevent the connecting rod 7 and the sensor 10 from being displaced, thereby improving stability. After the sensor 10 has completed detection, the connecting rod 7 is pulled upward to pass through the top adjustment plate 62 again and the second positioning bolt 63 is turned to fix it. The adjusting plate 62 is pushed upward by starting the cylinder 61, which drives the connecting rod 7 upward. When the length of the connecting rod 7 is relatively long, the support plate 4 is driven upward by the adjusting plate 33, which drives the connecting rod 7 further upward, so that the sensor 10 is separated from the foundation pit.
[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
