The effect of embodiment
The utility model is related to combined type rectangular push-bench include several rectangular pipe jacking machines being detachably connected, use
When can be adjusted according to the size in tunnel to be excavated, rectangular pipe jacking machine is connected together, cooperate obtain needed for ruler
Very little excavation surface.It solves and can not start in time because separate unit rectangular pipe jacking machine excavation surface is mismatched with tunnel size to be excavated
The problem of excavating, delaying the duration.
Rectangular pipe jacking machine has the small cutterhead positioned at the central cutterhead at front opening center and positioned at four angles of front opening,
When operation, rotary cutting, mutual cooperation can obtain up to 90% or more the area of cut, reach good five cutterheads simultaneously
Cutting effect.Four small cutterheads are located at four angles of rectangular pipe jacking machine so that rectangular pipe jacking machine can be good at disperseing stress, group
Combined type rectangular push-bench is integrally with good stability when cooperation industry so that work progress can be smoothed out.
The circumference of center cutterhead in rectangular pipe jacking machine and the plane where four side walls are tangent, four small cutterheads respectively with
Plane where the side wall of corresponding position is tangent, such structure make rectangular pipe jacking machine during excavation between each other not
It interferes, respective operation, while can work in coordination and uniformly crush the native stone in excavation surface again, obtain maximum crushing
Effect.
Further, due to the unbalance stress of knife plate in mining process, the outermost end stress of knife plate is maximum, has maximum
Deformation quantity.Central cutterhead is using trapezoidal knife plate in the utility model, what the width of the trapezoidal knife plate extended along trapezoidal knife plate
Direction gradually increases, and such knife plate structure design has well adapted to the stressing conditions of knife plate in mining process.Trapezoidal knife plate
Outermost end width it is maximum, the resistance that be subject to when will can excavate well and frictional force dispersion reduce deformation quantity, and then reduce ladder
The abrasion of shape knife plate outermost end solves the problems, such as that knife plate is easily damaged well.
Central cutterhead has several ring stiffeners being fixed on trapezoidal knife plate, can reinforce the different location of knife plate
Intensity, and then the uniform intensity for improving solid cutter so that central cutterhead has longer service life.A wherein annular
Reinforcing rib is fixed on the outermost end of trapezoidal knife plate, individually reinforces the trapezoidal maximum outermost end of knife plate stress, reduces ladder
The impaired possibility of shape knife plate outermost end.Central cutterhead also have with the integrally formed bar shaped reinforcing rib of ring stiffener, into one
Step improves the integral strength of cutterhead, solves the problems, such as that cutterhead intensity is low well.In addition, due to using reinforcing rib to cutterhead
Intensity is reinforced, and there is gap so that not will produce excessive stress surface while improving cutterhead intensity makes knife between reinforcing rib
Consolidation body is by extra resistance and frictional force.It is also fixed with sharpener on bar shaped reinforcing rib, the cutting of central cutterhead is played auxiliary
The effect helped improves the crush efficiency of central cutterhead.
Four small cutterheads have the rectangular small knife plate of three block lengths, compensate for the problem of central knife cutting area deficiency so that
Native stone in entire cutting face can obtain enough crushing, reduce the jacking pressure of push-bench, ensure that excavates is smoothed out.
The ring stiffener of pocket knife edges of boards edge is fixed on intensity of the outermost end of three pieces of small knife plates for reinforcing small cutterhead, improves small cutterhead
Service life.
The above embodiment is the preferred case of the utility model, is not intended to limit the scope of protection of the utility model.
Connection component in the utility model can also be to snap connection.It is fixed on the side wall of one rectangular pipe jacking machine 1
Five groups of fixing pieces, five groups of fixing pieces are separately positioned on the center and four angles of side wall, another rectangular pipe jacking machine 1 it is corresponding
Position is fixed with and the matched locking member of fixing piece.Locking member is reversed in push-in fixing piece when fixed, then turn-back will
Two rectangular pipe jacking machines 1 are fixed.
