Description

Technical Field

[0001] The utility model relates to the field of pipeline excavation devices, in particular to a pipeline excavation device for municipal engineering. Background Art

[0002] Municipal infrastructure projects refer to the civil engineering, pipeline and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardening, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities and ancillary facilities.

[0003] In the prior art, before the sewage pipes of municipal engineering are laid and installed, it is often necessary to dig a buried pipe groove on the ground by a grooving device. The Chinese utility model patent with the publication number "CN220499560U" and the patent name "A grooving device for sewage pipe construction" discloses a grooving device for pipe construction, which is used to dig the pipe groove before the pipe construction. The patent records that "the threaded rod 2 is driven to rotate by rotating the hand-held turntable, thereby driving the assembly of the clamping plate and the slider Slide on the surface of the mounting seat and move the clamping plate away from the mounting disk, so that the bearing at the end of the clamping plate is detached from the end of the rotating shaft; then remove the nut, and then remove the pressure plate and the pressure ring, so that the assembly of the plug-in plate, the arc-shaped plate and the crushing tooth is exposed, so that the damaged crushing tooth can be removed and replaced with a new one, and then the pressure plate, the pressure ring and the nut are installed in sequence. Finally, rotate the turntable in the opposite direction to make the clamping plate close to the mounting disk again, so that the bearing sleeve is installed at the end of the rotating shaft. Thereby achieving the purpose of facilitating maintenance";

When digging a complete pre-buried groove for the pipeline, the grooving operation needs to be repeated until the width of the pre-buried groove for the pipeline matches the diameter or width of the pipeline, thereby reducing the work efficiency of digging the pre-buried groove for the pipeline during the construction of municipal engineering pipelines;
