[0001] The utility model relates to the technical field of engineering monitoring, in particular to a foundation pit measuring device. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage should be done well. After the foundation pit is excavated, its depth needs to be measured using a measuring device so that the staff can master the data for later construction.

[0003] After searching, the patent with publication number CN219474505U proposed a foundation pit depth measuring device, which drives the collecting roller to rotate through a driving motor, and the measuring rope is lowered. When the pressure sensor touches the bottom, the alarm sounds, and the camera records the falling length of the measuring rope, thereby achieving the effect of automatic measurement of the measuring device. However, when the device is actually used, the measuring rope will shake during the lowering process, and it is necessary to wait for the measuring rope to stabilize before reading, so the measurement process is not fast and stable enough. Secondly, the device can only measure the depth of the foundation pit, not the width of the foundation pit, and the measurement range is limited. Therefore, further improvement is needed.

[0026] The vertical rod 3 can rotate in the fixing tube 2. When the device is not in use, the vertical rod 3 can be rotated so that the cross plate 4 and the box body 5 are located above the vehicle plate 1, thereby reducing the space occupied by the device. When in use, the vertical rod 3 is rotated again so that the box body 5 is located on the side away from the vehicle plate 1, and then the locking bolt 17 is rotated to fix the vertical rod 3.

[0027] like Figure 2 and Figure 3 As shown, the adjustment assembly includes a servo motor 8 fixed inside the box body 5 and a second gear 10 fixed to the surface of the adjustment shaft 6.
