Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 2-Fig. 7, a kind of bucket of excavator, comprises bucket main body, and bucket main body comprises two side plates 11 and base plate 13; Two side plates 11 all have cambered surface limit 11a, and base plate 13 is fixedly connected between the cambered surface limit 11a of two side plates 11; One side of base plate 13 is fixed with labial lamina 15, labial lamina 15 is fixed with bucket tooth 14, also comprise a pair blade 30 and a pair corner 20; Corner is mainly used in face excavation, finishing and sidewall bottom finishing, and blade is used for excavation and the finishing of side wall upper part camber line position of tunnel tunnel face upper space.
A pair blade 30 is separately positioned on the lateral wall of two side plates 11, and the top of blade 30 upward; Conveniently fixed blade 30, when specifically implementing, side plate 11 lateral wall is installed with the buckle 11b for clamping blade 30, during use, the bottom of blade 30 is stuck in buckle 11b, and conveniently, it is bigger that buckle 11b can do, buckle 11b is coordinated with the bottom gap of blade 30, thus when bucket down, namely blade top down time, this blade 30 can come off under its Action of Gravity Field from buckle 11b, do not need specially to dismantle, easy to use.
When earth tunnel rock integrity better, intensity is lower, crack is comparatively grown, without underground water, during the short 0.5 ~ 1.0m of cyclic advance, blade and corner can adopt the structure in Fig. 3 and 4.
Blade 30 two sides are respectively equipped with the projection 31 to extending away from blade 30 side, and projection 31 is positioned at the top of blade 30.Projection 31 can make triangular structure.And with the side of blade, there is the angle of 30-60 °.
The longitudinal section in corner 20 is trapezoidal, has leg-of-mutton groove 21 bottom it.Conveniently be welded on outside bucket body top.Corner 20 is installed in outside bucket body top, and a pair corner 20 is arranged on the both sides, front and back of bucket body top (see Fig. 2, before sight line can be seen that the direction of side plate is defined as, paper extends internally, the direction of the side plate that sight line be can't see is defined as rear), during concrete enforcement, the both sides, front and back of what corner was passable be welded on bucket body top, the angle of corner and bucket body top camber line is 135 °.When front is when digging, the soil of bucket front and side can well be repaired.
When earth tunnel rock integrity is good, intensity is higher, crack agensis, and during the larger 1.0 ~ 2.0m of cyclic advance, corner and blade can adopt the structure in Fig. 6 and 7.
Blade 30 two sides are respectively equipped with the projection 31 to extending away from blade 30 side, and projection 31 is positioned at the top of blade 30, and projection 31 can make triangular structure.And with the side of blade, there is the angle of 30-60 °.Projection 31 its booster action main, can play reinforcement excavation effect, simultaneously when repairing sidewall, can also play the effect of subsidy finishing.The top of blade 30 is reclinate hook assembling structure 33, when soil property is harder, is more conducive to the soil property excavating bucket top and side.Blade 30 thickness is at about 5cm.
The longitudinal section in described corner 20 be trapezoidal, such structure in digging process, the damage area of its corner to the soil body can be improved on the one hand, on the other hand, the degree of wear in corner can be reduced, improve the useful life in corner.There is bottom corner leg-of-mutton groove 21, the front-rear side walls in corner 20 is connected to the welded top of reinforcing the solid steel bar 22 of steel bar 22, two and fixes.Conveniently install additional and dismantle and reinforce steel bar 22, multiple bolt hole can be set on the front-rear side walls in corner, by bolt and bolt hole, reinforcing steel bar 22 be fixed on the front-rear side walls of corner 20.Reinforce arranging of steel bar and enhance the destructive power of corner to the soil body on the one hand, add the scope of this corner finishing on the other hand, improve the applicability in corner.
Earth tunnel mechanical equivalent of light excavation and owe the process of digging finishing: during tunnel excavation, bucket moves downward excavation, returns when moving upward and utilizes corner to excavate, improves excavation efficiency, needs to carry out face and the deficient of side edge angular position digs process after excavation.Face is surrounding corner mainly, and sidewall is top and bottom mainly.When carrying out owing to dig process, first revise face, adopt the corner on transformation bucket both sides to process, processing sequence is first top, then surrounding, last bottom; The deficient of tunnel-side digs process, owes excavator body, then install blade in bucket side, by the deficient excavator body of blade cut side wall upper part, repair by the corner process lower sidewall of bucket.
Adopt the bucket after repacking to excavate tunnel and owe to dig finishing process, excavation efficiency can be improved, substitute the finishing of artificial secondary, ensure construction safety, also accelerate the speed of finishing simultaneously, save time, steel arch-shelf can be established as early as possible, support in time, guarantee the stable of tunnel.Simple to the method for modifying of bucket, to owe to dig finishing operation simple and direct, workable and safety is high.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
