Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a hole depth measuring device. Background Art

[0002] The hole depth must be measured multiple times during the drilling and pouring of concrete in pile foundation projects. If the geology is good and the dry drilling process is used, the hole depth can be measured directly with a steel ruler. If the geology is poor and the mud wall mechanical drilling process is used, a measuring rope is generally used for measurement. The commonly used method for measurement is to measure the length of the rope.

The beneficial effect achieved by the utility model is that by setting the pay-out assembly, the pendant at one end of the pay-out rope can be placed into the pile foundation hole to be measured, so as to facilitate the depth measurement of the pile foundation hole, and by setting the disassembly assembly, the pay-out device and the placement device can be separated and carried, thereby achieving the purpose of convenient carrying.

[0004] However, the above patent has the following shortcomings: the above patent reels the pay-out rope through a rope roller, but during use, the pay-out rope will be entangled in one place and cannot be evenly wound around the rope roller, which may cause the pay-out rope to become knotted, and thus it needs to be improved.

[0028] Specifically, when the measuring line 8 is evenly wound on the take-up roller 7, the first motor 3 is started to drive the screw rod 4 to rotate back and forth during the rotation of the first motor 3. The threaded block 12 is driven to move back and forth through the threaded block 12, and the rectangular frame 13 is driven to move back and forth through the rectangular frame 13. The measuring line 8 in the winding process can be adjusted back and forth through the rectangular frame 13 to prevent the measuring line 8 from being wound together and causing knots.
