Embodiment 2
[0024] On the basis of Embodiment 1, a cavity 10 is provided inside the connecting rod 2, a motor 11 is provided at the lower end of the cavity 10, and a threaded rod 12 is provided at the output end of the motor 11, and the threaded rod 12 is provided at the output end of the motor 11. The rod 12 is provided with a slide block 6, the inside of the slide block 6 is provided with a threaded hole 13 cooperating with the threaded rod 12, and the left and right symmetry of the cavity 10 is provided with a chute 14 for the slide block 6 to slide. The left and right ends of the block 6 are hinged with driving rods 7, and the lower ends of the driving rods 7 are hingedly connected with the two handles of the detection pliers 1 respectively. The upper end of the support rods is provided with a wireless controller and a display screen. After arriving at the bottom of the inspection shaft, the captured pictures can be effectively wirelessly transmitted to the display screen through the c...

The invention relates to the technical field of detection pincers, in particular to underground pipeline detection pincer equipment. The underground pipeline detection pincer equipment comprises detection pincers and a connecting rod, a supporting rod is connected to the upper side of the connecting rod through a connecting device, and composed of several short rods, every two adjacent short rodsare connected through the connecting device, and the connecting device comprises a connecting base; fixed cavities are symmetrically formed in the connecting base, fixed holes are formed in the outerends of the fixed cavities, inclined faces are arranged at the portions, close to the fixed holes, of the interiors of the fixed cavities, several locating rings are arranged on the inclined faces, fixed cylinders are arranged at the portions, away from the fixed holes, of the interiors of the fixed cavities, locating springs are arranged at the outer sides of the fixed cylinders, one ends of thelocating springs are connected with the fixed cavities, and the other ends of the locating springs abut against the locating rings. The underground pipeline detection pincer equipment is convenient todetach, install and carry, the number of the short rods can be adjusted according to the working depth, different using requirements are met, and the using comfort is improved.
Description
technical field [0001] The invention relates to the technical field of detection pliers, in particular to underground pipeline detection pliers equipment. Background technique [0002] The underground pipeline detector is an instrument used to detect the direction and buried depth of underground pipelines. It is composed of a transmitter, a receiver, an induction clamp and a grounding rod. The clamp is connected to the pipeline under test in the well. During detection, the transmitter applies a signal frequency to the pipeline, and the receiver detects the location of the pipeline by receiving the signal. During the detection process, there are few exposed points of pipelines on the ground, and most of them are in inspection wells. The connection between the transmitter and the induction clamp and the measured pipeline must be operated in the well. Operators will face suffocation, unknown gas poisoning and Risks such as downhole falling. [0003] Chinese patent (authorize...
