Description
Technical field
The utility model relates to the realm of building construction, particularly relates to a kind of earth tunnel excavating device of speedway.
Background technology
At present, in the earth tunnel work progress of speedway, for part weak surrounding rock, its intensity is relatively low, globality is relatively poor, blast working can not play Smooth Blasting Effects, in practice of construction, in order to reduce phenomenon of backbreaking, end face periphery reserved part country rock, section finishing is carried out after bursting work terminates, it is slower that artificial hand-held pneumatic pick carries out erection rate to section reserved part after explosion, do not meet construction needs, when excavator is repaired, because excavator bucket teeth active area is larger, pawl trace can only be left on rock mass surface, block cannot be become to excavate, cause construction speed slow, operating efficiency is low.
Utility model content
The purpose of this utility model is to solve the problem, and provides that a kind of structure is simple, dependable performance, the excavating device that easy to use, efficiency is high, carries out suitable transformation, can carry out the driving of earth tunnel to existing excavator.
To achieve these goals, the technical solution adopted in the utility model is:
An earth tunnel excavating device for speedway, comprises excavator, excavation cutter, cutter draw-in groove and cutter block, described excavation cutter comprises cutter tip and cutter body portion, the cross section of described cutter tip is triangle, angle between described cutter tip and cutter body portion is 120 degree to 160 degree, described cutter tip and cutter body portion one-body molded, described cutter draw-in groove is welded on the left and right sides wall of excavator bucket, described cutter body portion snaps fit onto on bucket by cutter draw-in groove, described cutter block is welded on excavator bucket, the end in cutter body portion contacts with cutter block, described cutter draw-in groove number is at least two, described cutter draw-in groove interval is arranged, the end both sides in described cutter body portion have transition face.
Wherein said excavation cutter adopts the thick Q235 general steel plate processing and fabricating of 4cm to form.
Wherein said cutter draw-in groove adopts the thick Q235 general steel plate processing and fabricating of 4cm to form.
Wherein said cutter block adopts the thick Q235 general steel plate processing and fabricating of 4cm to form.
Angle between wherein said cutter tip and cutter body portion is 154 degree.
Wherein said excavator matches with the requirement of excavation operation.
The beneficial effects of the utility model are: reasonable in design, ingenious, easy to make, improving cost is low, installing/dismounting comparatively fast, simply, guaranteeing the structure not destroying each working cell, original soil matter tunnel excavation face, improve production efficiency, fully ensure that the safety problem of operative, application is strong simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
An earth tunnel excavating device for speedway, comprises excavator, excavation cutter 3, cutter draw-in groove 4 and cutter block 5, excavation cutter 3 comprises cutter tip 1 and cutter body portion 2, the cross section of cutter tip 1 is triangle, angle between cutter tip 1 and cutter body portion 2 is 120 degree to 160 degree, cutter tip 1 and cutter body portion 2 one-body molded, cutter draw-in groove 4 is welded on the left and right sides wall of excavator bucket, cutter body portion 2 snaps fit onto on bucket by cutter draw-in groove 4, cutter block 5 is welded on excavator bucket, the end in cutter body portion 2 contacts with cutter block 5, cutter draw-in groove 4 number is at least two, cutter draw-in groove 4 interval is arranged, the end both sides in cutter body portion 2 have transition face 6.
During concrete making, according to the size of required excavation cutter, utilize cutting technique to be processed by steel plate thick for 4cm, the Atria limit size of cutter tip 1 cross section is respectively: 30cm, 40cm, 50cm.
The setting space of cutter draw-in groove 4 is 15cm.
The transition face 6 that the end both sides in cutter body portion 2 are arranged is arcwall face.
In work progress, after excavator bucket dig on a wide area completes, by excavation Cutting tool installation manner in the cutter draw-in groove of bucket, push to cutter block, fixedly complete, namely start the digging arm of excavator, excavation cutter is repaired excavation contour line, after having repaired, excavation cutter can be disassembled, bucket can continue dig on a wide area.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., be all included within protection domain of the present utility model.
