Excavating equipment for trenchless pipe jacking construction

Abstract

The invention discloses excavating equipment for non-excavation pipe jacking construction, which comprises a movable bottom plate, a lifting plate is movable above the moving bottom plate, a rotating support plate is horizontally arranged above the lifting plate, and a mounting plate is arranged on the moving support seat. There are three moving crawlers arranged on the peripheral side of the mounting seat, the moving crawlers and the mounting seat are connected by connecting rods, a rotating shaft is arranged laterally on the inner side of the mounting seat, and a third motor is fixedly installed on one end of the mounting seat. The output shaft end of the motor is fixedly connected to one end of the rotating shaft, and the end of the rotating shaft away from the third motor is fixedly equipped with an excavating bit; the excavating equipment is convenient for controlling the position of the excavating bit, and the positioning is accurate, and it is convenient for the excavating bit to move to the pipeline Among them, the digging bit can move automatically, saving time and effort, and reducing labor intensity. At the same time, the digging bit can move in pipes of different sizes, and has strong adaptability.

Description

Technical field [0001] The present invention relates to the field of non-opening tape engineering, in particular, to a non-open tape pipe construction excavation device. Background technique [0002] Non-excavation technology refers to laving, repairing and replacing pipelines, repairing and replacing pipelines using geotechnical drilling techniques without excavating or excavating a small amount of job pits, which does not affect environmentally, high-quality, cost, and environmentally friendly. The advantages of transportation, non-polluting environment, in many cases, short-range construction cycle, low comprehensive cost, good security, has become the main means of urban municipal construction; patent documents (CN110513534A) discloses municipal sewage pipelines Excavation construction method, the construction passes through the drill pipe, the drill rod is inconvenient to move to the pipe, and the installation is inconvenient in the working well, the position of the drill pi...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an excavating equipment for trenchless pipe jacking construction. By starting the first motor and cooperating with the second gear and the second gear to drive the rotating support plate to rotate, the rotating support plate drives the mobile support to rotate. Thereby driving the excavation bit to rotate, the direction of the excavation bit is adjusted, by arranging the lifting plate moving in the vertical direction under the rotating support plate, the lifting plate is driven up and down by the first cylinder, and the lifting plate drives the mobile support to rise, thereby The height of the excavation bit is adjusted, which solves the technical problems of inconvenient adjustment and inaccurate positioning of the excavation equipment bit for traditional non-excavation pipe jacking construction;
