Abstract
The utility model provides a follow -on pipe pushing jack blade disc which the main points lie in adding at the edge on pipe pushing jack blade disc surface has welded the shell sword, and the cross section of shell sword is semi -circular for excessively, by top central authorities to five wear -resisting teeth of high -strength alloy of both ends evenly distributed. The beneficial effects of the utility model are that to the less input makes ordinary pipe pushing jack possess certain broken barrier function, can solve and advance the great barrier of intensity that the in -process probably runs into on the top.
Description
Technical field
The utility model relates to and improving among a small circle push-bench cutterhead, helps push-bench to have certain barrier-breaking function, the especially comparatively hard formation such as cement fender post or strong-weathered rock.
Background technology
As shown in Figure 1, the single cutter tooth of many employings is to adapt to correspondingly layer soil body for general push-bench cutterhead.But due to the unicity of function, cause the strain capacity of push-bench poor, once run into the comparatively hard formation such as cement fender post or strong-weathered rock in jack-in process, the rock breaking capacity of its extreme difference often causes body jacking slow, even occurs that head gets stuck and cannot continue the situation of jacking.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming the existence of existing push-bench cutterhead, provides a kind of follow-on push-bench cutterhead, improves knife cutting power, increases the function of cutter tip, the strain capacity of push-bench is strengthened greatly.
The technical scheme that the utility model adopts is: a kind of follow-on push-bench cutterhead, its main points are to be welded with shell cutter at the edge on push-bench cutterhead surface, the cross section of shell cutter was semicircle, was uniformly distributed five resistance to roll flutes of high-strength alloy by mediad two ends, top.
The utility model improves on existing push-bench cutterhead, is welded with shell cutter at the edge on its surface, and the intensity of shell cutter is greater than former knife cutting cutter, has stronger cutting force, utilizes the semicircular characteristic of its cutter tooth, to the cutting of obstruction more comprehensively.
The central angle of the resistance to roll flute of shell cutter both sides high-strength alloy is 110-130 degree.
The wear-resisting tooth tip of high-strength alloy of shell cutter exceeds 3 ~ 4cm than the bite on cutterhead.The leading cutting soil of such guarantee shell cutter, after being cut by obstruction (cement fender post or strong-weathered rock), then is frittered by the bite followed up and grinds, drain in push-bench finally by mudhole.
The central angle distributions such as multiple shell cuttves.
There are the central angle distributions such as 6 shell cuttves.The every 60 degree of intervals of hoop are welded with shell cutter again, make shell cutter entirety be that quincuncial arrangement is on cutterhead.
Multiple shell cutter radially distributes.
Three shell cuttves are radially distributed with along cutterhead.
Be radially distributed with three shell cuttves along cutterhead, often enclose 6, totally 18.6 shell cuttves are furnished with as the cutterhead of radius 1.8m often encloses at 0.6m, 1.2m, 1.8m place.
The beneficial effects of the utility model are, make ordinary topping pipe facility for certain barrier-breaking function with less input, can solve the obstruction that the intensity that may run in jack-in process is larger.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is conducted further description
As in Figure 2-4, a kind of follow-on push-bench cutterhead improves on the basis of former push-bench cutterhead, shell cutter 4 is welded with at the edge on push-bench cutterhead 1 surface, the cross section of shell cutter 4 was semicircle (being not less than semicircle), was uniformly distributed five resistance to roll flutes 41 of high-strength alloy by mediad two ends, top.The central angle of the resistance to roll flute 41 of shell cutter 4 both sides high-strength alloy is 110-130 degree.High-strength alloy resistance to roll flute 41 top of shell cutter exceeds 3 ~ 4cm than the bite 2 on cutterhead 1.The leading cutting soil of such guarantee shell cutter, after being cut by obstruction (cement fender post or strong-weathered rock), then is frittered by the bite 2 followed up and grinds, drain in push-bench finally by mudhole 5.There is multiple central angle such as shell cutter 4 grade to distribute, be distribution such as central angle such as 6 shell cuttves 4 grade in figure, between every 60 degree, be separated with a shell cutter, make shell cutter entirety be that quincuncial arrangement is on cutterhead.Meanwhile, be radially distributed with in multiple shell cutter 4, figure and be radially distributed with three shell cuttves 4 along cutterhead 1.To be circular layout three road shell cuttves 4 along cutterhead 1, overall in quincunx, often enclose 6, totally 18.6 shell cuttves are furnished with as the cutterhead of radius 1.8m often encloses at 0.6m, 1.2m1.8m place.It is same as the prior art that all the other do not state part.
