Abstract

The invention discloses an intelligent tube push bench cutterhead which comprises a jacking-in disk, a central controller and an alarm, wherein the jacking-in disk is round; along the jacking-in direction, a pressure sensor and uniformly distributed drills are disposed on the front end face of the jacking-in disk, a first motor is fixed on the rear end face of the jacking-in disk, and the drills are connected to a power output shaft of the first motor; center shafts of the drills are placed horizontally; and the pressure sensor, first motor and alarm are connected to the central controller by electric signals. The intelligent tube push bench cutterhead disclosed by the invention has the beneficial effects that whether the drills reach a maximum drilling depth can be detected automatically in time; cutter damage can be prevented; retraction and jacking-in actions of cutters can be controlled automatically; a lot of manual workloads are saved; the cutters are automatically controlled to deflect at multiple angles and then start drilling into rock soil; soil drilling effects are better; and the rock soil can be stripped and excavated more easily.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking engineering equipment, and in particular relates to an intelligent pipe jacking machine cutter head. Background technique [0002] With the development of urban economy and the expansion of city scale, there are more and more constructions of various municipal projects such as subways, cross-river tunnels, and sewage pipelines. As a non-excavation construction method for laying underground pipelines, the pipe jacking construction method has little impact on the surrounding environment and relatively low cost, so it has been widely used. During the pipe jacking construction process, the concrete pipe is pushed through the soil layer by means of the jacking force from the oil cylinder or jack, and the subsequent pipe is buried. Its greatest advantage lies in the use of underground excavation without slotting way, thereby avoiding the direct impact on the buildings or structures on the ground. ...
