Description
Technical field
The present invention relates to dregs Removal Technology field, the earth moving equipment and its dregs for transporting the earthwork are related in particular to
Pour out method.
Background technique
In current metro construction, the muck haulage mode of excavation of foundation pit mainly uses integral type soil case.The integral type
Native case is that the soil at hole bottom is sent into native case by excavator using step, and tower crane is recycled to catch on four suspension hooks of native case to sling
Native case；When needing to topple over dregs, pine removes two suspension hooks of native case side, and native case is made to tilt i.e. pourable dregs.
It is worth noting that, existing integral type soil case is in practical operation, there are following technical problems:
1) existing native case needs vacantly to sling native case and complete unilateral side and topples over to fall dregs when toppling over native slag
Out, such operating procedure complexity is cumbersome, and the working strength for not only increasing construction personnel reduces working efficiency instead, while also increasing
The danger coefficient of big construction personnel.
2) existing native box structure is mainly formed between opposite bottom wall and top opening and top bottom side wall there are four tools
It encloses and sets composition, side wall has relatively low structural strength due to top formed for opening；However, existing soil case is being toppled over
When dregs, native slag can simultaneously be inclined to same side wall and concentrate, and side wall is caused to be easy because meeting with gravity pressurization suddenly due to deformed damaged,
Cause the reduced service life of native case.
3) since the sticky soil body is there are certain cohesive strength, even the undamaged native case of structure is also easy to happen
Part dregs remains in the situation on the inner wall of native case, in the native case for leading to deformation after toppling over operation, it is easier to shape
At dregs stagnant area, more residues are had accumulated in native case, so that reducing native case effectively carries soil amount and native case service efficiency；
4) existing slag removal tool mostly uses greatly manual cleaning, low there are working efficiency and scarfing cinder is not certain etc. asks
Topic；
5) has the technical solution for carrying out scarfing cinder to native case using unartificial mode at present, wherein again with the effect of vibratory cleaning
Rate highest；However, there is following technical problem in actual use in existing vibratory cleaning equipment:
(1) vibration is to hit Tu Xiangdibi by vibrator to generate, therefore can generate very big noise pollution；
(2) energy consumed is high.It needs persistently to generate kinetic energy to equipment；
(3) most vibrators are fixedly mounted at native bottom portion, the cleaning effect phase that can be played for dregs on side wall
When limited, the side wall especially deformed is even more to be difficult to play the role of cleaning.
According to upper, it is really necessary to improved necessity for aforementioned integral type soil case.
Summary of the invention
In view of the foregoing, the present invention provides a kind of earth moving equipment and its dregs pours out method, by by the bottom of native case
Be configured to can the movable floor that turns over of pivot, cooperate and the switching on and shutting down being either open or closed to control the bottom plate be set in native case side wall
Structure allows the dregs in native case by switching the movable floor, using the weight of dregs itself, dregs is made to open bottom plate
Shi Zidong is poured out from the bottom opening of native case, does not need solve native packing list inclination to tilt down soil by being sling by unilateral side tiltedly
Soil, which is easily damaged to split extension and reduce native case, effectively carries soil amount and the technical problems such as service efficiency, reaches quick, convenient, high
The purpose of efficiency transport dregs.
To achieve the above object, the technical solution adopted by the present invention is that providing a kind of earth moving equipment, comprising: native case ontology,
It is formed with opposite top opening and bottom opening, the soil case body bottom portion corresponds to the bottom opening and is pivoted with a dump bottom
Plate；Switching mechanism is set to case ontology side, opens wide or close the bottom opening to control the movable floor.
Earth moving equipment of the present invention further improvement lies in that, it is described soil case ontology have opposite the first side wall and second side
Wall, the first side wall are equipped with the switching mechanism, and the second sidewall root edge and the movable floor are pivotally connected；The activity
Bottom plate is equipped with two limited bolts towards the end of the switching mechanism；The switching mechanism includes positioning trunnion mount, latch knob, positioning
Crotch and traction piece, the positioning trunnion mount are fixedly arranged on the first side wall, and the latch knob is rotationally articulated in described
It positions in trunnion mount, the positioning crotch is hubbed on the first side wall and is consolidated by the traction piece and the latch knob
It connects；The traction piece is tensed by rotating the latch knob, the positioning crotch pivots and fastener fastens described two to draw
Limited bolt enables the movable floor close the bottom opening of the native case ontology；Or by rotating the latch knob relaxation
The traction piece is pivoted and is unclasped to draw the positioning crotch and recess two limited bolt, the movable floor is enabled to open wide institute
State the bottom opening of native case ontology.
Earth moving equipment of the present invention it is further improvement be, the switching mechanism include positioning trunnion mount, a latch knob,
Two positioning crotches and two traction pieces；Wherein, the positioning trunnion mount is set on the first side wall；The latch knob is configured to T
Shape structure has a shaft and a control-rod, and the both ends of the shaft is hubbed in the positioning trunnion mount, and the shaft passes through institute
Control-rod traction is stated to rotate relative to the positioning trunnion mount；Described positioning crotch one end is equipped with the first centring point, and the other end is configured to
Hook portion, and the second centring point is equipped on the outside of the hook portion；The positioning crotch is hubbed at described first by first centring point
On side wall；Two traction piece is fixedly arranged at the pivot both ends of the latch knob, each traction piece have opposite end, one
End is fixedly connected with the end of the pivot, and the second centring point of the other end and the positioning crotch is pivotally connected；The switching mechanism is logical
It crosses and rotates the latch knob drive traction piece traction two positioning crotch disengaging or hook two limited bolt, with
The movable floor is set to open wide or close the bottom opening.
The further improvement of earth moving equipment of the present invention is that the positioning trunnion mount weldering is set on the first side wall, institute
It states positioning trunnion mount and is formed with two pivot hole, the both ends of the shaft of the latch knob and two pivot hole, which are planted, to be pivotally connected.
The further improvement of earth moving equipment of the present invention is that the traction piece is that fine steel rib or steel strand wires are constituted；It is described
Traction piece one end is affixed by the roller end of the first anchor bolt and the latch knob；The other end by the second anchor bolt with it is described fixed
The second centring point pivot joint of position crotch.
