Underground pipeline detection clamp with safety protection structure

Abstract

The invention discloses an underground pipeline detection clamp with a safety protection structure, and belongs to the technical field of pipeline detection. The clamp includes a clamp body; the left end of the clamp body is rotatably connected to two holding handles; the end, away from the clamp body, of the holding handle on the lower side is connected to a detection line; the left ends of the holding handles are provided with threaded grooves; the threaded grooves are located on the upper side of the detection line and in threaded connection with L-shaped rods; the left sides of the holding handles are provided with elastic positioning rings; the L-shaped rods and the detection line are sleeved by the elastic positioning rings and respectively in contact with the inner top ends and inner bottom ends of the elastic positioning rings. Thus, reinforcement on the detection line can be realized, and the connecting part between the detection line and the clamp body are not easily loosened when the detection line is driven to shake during the using of the clamp body, or the fracture of the connecting head part of the detection line due to too many shaking times is not easy to happen.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to an underground pipeline detection clamp with a safety protection structure. Background technique [0002] Pipeline detection is mainly to detect the direction and buried depth of underground pipelines without excavation. Generally, pipeline detectors are used for detection. In the process of pipeline detection, transmitters, detection clamps, and receivers are mainly used. A signal current of a special frequency is applied to the measuring pipeline. Generally, the corresponding pipeline is clamped by the detection clamp, and the clamp method is used to excite the mode. The receiver has a built-in induction core to receive the magnetic field signal of the pipeline, and the coil generates an induced current to calculate the pipeline direction and path. [0003] One of the gripping handles of the detection clamp is connected with a detection line. The detection line is l...
