Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to underground pipeline detection auxiliary equipment. Background Art

[0002] The main purpose of underground pipeline detection is to find out whether there are any underground pipelines already laid at the construction site. If so, the plane position, burial depth, nature, material, etc. of the underground pipelines will be found out, and an underground pipeline map will be compiled. The laying year and property unit of each pipeline should also be found out to better protect the existing underground pipelines. In the detection of underground pipelines, the manhole covers need to be removed, and then the detection personnel use some special detection equipment or conduct on-site field surveys in the wells.

[0003] The patent document with the prior art publication number CN217030538U provides an underground pipeline detection auxiliary equipment. Through the installed movable plate, load-bearing ball, spring and fixed rod, when the detection head moves down into the underground pipeline and tilts, the movable plate can drive the load-bearing ball inside the load-bearing block to squeeze or pull the spring. When the movable plate contacts the fixed rod, the movement of the movable plate can be limited so that the spring can pull the movable plate and the load-bearing ball to reset, thereby adjusting the inclination of the detection head in time. However, when the patent CN217030538U is in use, the current auxiliary equipment is placed above the wellbore. However, since the auxiliary equipment is equipped with moving wheels, the auxiliary equipment is prone to deviation and slippage, which in turn affects the detection of the detection equipment. Therefore, an underground pipeline detection auxiliary equipment is urgently needed. Utility Model Content
