Description
Technical Field
The invention relates to the field of push bench cutterheads, in particular to a turnover push bench cutterhead.
Background
The pipe jacking machine is used as a large-scale excavating device and is widely used in various tunnel constructions, a cutter head of the pipe jacking machine is used for excavating the main function of the pipe jacking machine in the pipe jacking machine, the pipe jacking machine excavates underground, and the geological condition is very complicated, so in order to ensure that the pipe jacking machine can stably and effectively work in different geological environments, the cutter head is required to have very strong adaptability, the pipe jacking machine can be roughly divided into two types according to the types of the existing cutter head according to the functions, one type is a cutter head which is specially used for excavating a uniform soft soil stratum or a hard soil stratum, the other type is a composite cutter head which is specially used for excavating a composite stratum with soft soil and hard rock, however, one section of the composite cutter head is a uniform soft soil stratum and the other section is a uniform hard rock stratum or a stratum mixed with the soft soil stratum in some areas in the actual excavating process, or a large rock block is suddenly encountered in the excavating process, the conventional method for the stratums of different geologies is to use a soft soil cutter head when excavating soft soil, replace a rock breaking cutter head when meeting hard rocks to break, or manually blast and remove when meeting rocks, the method is time-consuming and labor-consuming and has very low efficiency, and the other mode is a composite cutter head which can be used for breaking the rocks whether the soft stratum or the hard rocks are directly used, but a hob which is used for breaking the rocks on the composite cutter head can not rotate due to small friction force when excavating the soil, and serious abrasion can be generated for a long time;
an invention patent JP3244603B2 "shield machine" granted in japan discloses a structure in which an obstacle is cut by an auxiliary cutter head protruding forward and rotating;
it is made by rotatably disposing an auxiliary cutter head at the center of a main cutter head, a plurality of auxiliary cutter heads are also rotatably disposed on a panel portion of the main cutter head, and they have a function of freely extending and retracting toward the front, and when an obstacle or rock is encountered, the auxiliary cutter head and the plurality of auxiliary cutter heads protrude forward and rotate to cut the rock. However, this design has the following disadvantages:
1. the cutting area is limited, the rock can not be completely contacted, and only the part of the rock contacted by the hob can be cut, for example, the auxiliary cutter head or the outer ring of the auxiliary cutter head rest can not be contacted with the hob at the center, so that the part of the rock can not be effectively cut;
2. because the auxiliary cutter head is large in volume, when small rocks are encountered and the positions of the rocks are right opposite to the circumferential edges of the auxiliary cutter head or the auxiliary cutter head, the hob cannot contact the rocks, so that the rocks cannot be cut off, and therefore the adaptability is poor;
3. the number of the auxiliary cutter heads is limited, and the number of the hob cutters is also limited, so that when the auxiliary cutter head is used for rotary cutting, the number of times of extruding rocks in unit time is small, the crushing and cutting effects are poor, and the efficiency is low;
thus, the prior art/design has drawbacks.
