Description
Technical field
The utility model relates to a kind of excavator, particularly relates to being adapted at a kind of amphibian digging machine of moving voluntarily in land or several meters dark waters, excavating and load.
Background technology
Amphibian digging machine is a kind of excavation and loading machine of can come in and go out voluntarily mire, waters and land, sloping bank.Exploitation is transformed in the fish pond especially, and the irrigation and water conservancy irrigation canals and ditches are transformed, and the lake embankment is reinforced, and aspects such as river training obtain application more and more widely.But there is following several aspects shortcoming in present amphibian digging machine, can not finely satisfy the real work needs.
1, crawler belt adds the amphibian digging machine of floating box type, can guarantee lower grounding pressure, adaptation is travelled and operation at the very low turf moor of bearing capacity of soil, owing to be subjected to the restriction of height of crawler ground, its maximum operation depth of water is generally less than 2 meters, along with the degree of depth of paddling increases, the buoyancy that buoyancy tank is subjected to strengthens, the stability of excavator self is variation gradually, excavator is floated on the surface when the depth of water reaches 2 meters left and right sides, fixing self-position ability does not lose mining ability, can't adapt to the working environment in mire, waters more than 2 meters.
2, the wheeled amphibian digging machine of pontoon extra bus when entering the waters by land, can't change the excavator operating position and also will rely on auxiliary equipment such as hawser at the very low mire ground run of bearing capacity of soil in the water that can float hull.
3, pouring weight and motor as the very big power of counterweight reciprocating rotating consumption of arm, waste energy all the time.
Summary of the invention
The purpose of this utility model is to provide a kind of novel multiple grab-buckets climbing type amphibian digging machine, to overcome the shortcoming that existing amphibian digging machine exists, not only is fit to land work, also is particularly suitable for working in darker mire, waters.
Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:
A kind of multiple grab-buckets climbing type amphibian digging machine, it is made up of power assembly, main frame float, the arm that has a grab bucket, power assembly 14 is fixed in the cabin of main frame float 11, do not rotate with arm 8,3～5 column spinners 13 of circumferencial direction distribution at main frame float 11, on each column spinner 13 arm 8 is installed all, grab bucket 1 is connected with arm 8 by semi-girder 4, grab bucket 1 is the excavation hand, also can be to move creep pin and feet, column spinner 13, arm 8, semi-girder 4 and grab bucket and 1 pass through HYDRAULIC CONTROL SYSTEM by power assembly 14.
Said angle of revolution as the grab bucket 1 of excavating hand can be divided into secondary, and the first order is the angle of revolution of grab bucket 1 relative main frame float 11; The second level is main frame float 11 relative other angles of revolution as the grab bucket 1 of feet, and the 1 total angle of revolution of grabbing bucket equals the summation of two-stage rotary angle.
Said grab bucket 1 is arranged in the lower end of semi-girder 4, and opening with closing by the torsion bar oil cylinder 5 that is arranged in semi-girder 4 upper ends of grab bucket 1 controlled by the long torsion bar 2 through semi-girder 4.
Said grab bucket 1 is during as feet, but Fast Installation float pin 24 on it, and the front end that the U type groove 20 of float pin 24 by 1 outside of grabbing bucket is clamped and installed in semi-girder 4 has on the U type groove junction plate 3.
Said hydraulic system comprises that torsion bar oil cylinder 5, semi-girder oil cylinder 7, arm oil cylinder 12 and column spinner oil cylinder 18 form with relevant oil circuit, torsion bar oil cylinder 5 is connected with long torsion bar 2 by torsion bar arm 6, one end of semi-girder oil cylinder 7 is hinged on the semi-girder 4, the other end is hinged on the arm 8, arm oil cylinder 12 1 ends are hinged on the arm 8, the other end is hinged on the column spinner 13, and column spinner oil cylinder 18 1 ends are hinged on the floor of main frame float 11, and the other end is connected with column spinner 13 by cursor/fluted disc 19.
Multiple grab-buckets climbing type amphibian digging machine mainly has grab bucket 1 arm 8 by power assembly 14,11,3～5 of main frame floats and forms.Its grab bucket 1 both can be used as moves the pin of creeping; Also can be used as the excavation hand, all grab buckets 1 all can be used as the pin of creeping when mobile.Excavator mainly relies on float 11 as main support when working in land and water, can select any grab bucket 1 as excavating hand, and other grab bucket 1 is responsible for the fixed-site of excavator and is changed the operating position as standing feet.Grab bucket 1 stand in water-bed maximum fording depth can equal 1 maximum digging depth of grabbing bucket.
The main feature that the utility model solves technical scheme that its technical problem adopts is:
1, power assembly 14 is placed in the cabin of main frame float 11, power assembly 14 not as the counterweight of arm 8 along with reciprocating rotating is swung.
2,3～5 column spinners 13 of circumferencial direction distribution at main frame float 11, arm 8 all is installed on each column spinner 13 successively, semi-girder 4, grab bucket 1, its grab bucket 1 both can be used as moves the pin of creeping, also can be used as the hand of excavation, grab buckets 1 all when mobile all can be used as the pin of creeping, can select any grab bucket 1 as excavating hand during work, other grab bucket 1 both can be used as the supplemental support pin of main frame float 11, also can be used as the feet of whole excavator, make the main frame float 11 complete built on stilts or the waters surface, or in water, reconcile the fording depth of main frame float 11.
3, can be divided into secondary as the angle of revolution of excavating hand grab bucket 1, the first order is for excavating the angle of revolution of hand grab bucket 1 relative main frame float 11; The second level is relative other angles of revolution as feet grab bucket 1 of main frame float 11, excavates the hand 1 total angle of revolution of grabbing bucket and equals the summation of two-stage rotary angle, between the grab bucket 1 any interference does not take place mutually.
4, grab bucket 1 and torsion bar oil cylinder 5 are arranged in the two ends of semi-girder 4, and opening and closing by long torsion bar 2 controls of torsion bar oil cylinder 5 through running through semi-girder 4 of grab bucket 1 guarantees that oil cylinder 5 does not enter in the water when working.
5, adopt the grounding pressure that float pin 24 structures reduction feet grab bucket 1 is installed, connection does not need other auxiliary component fast, the front end of semi-girder 4 has U type groove junction plate 3, there is U type groove 20 outside of grab bucket 1, wherein U type groove junction plate 3 restriction float pin 24 moves along axis direction, grab bucket 1 relies on when opening maximum position two U type grooves 20 to clamp float levers 23, and restriction float pin 24 moves in the vertical axis direction.
The beneficial effects of the utility model are: motor can be not as the counterweight of arm along with reciprocating rotating, and cancellation balancing weight reduces power consumption, saves the energy.Grab bucket can be used as the pin of standing, and reconciles the height of the relative supporting surface of main frame float, increases maximum excavator height, the maximum dump clearance of excavator on land.The grab bucket of this excavator can be used as the excavation hand again, and the maximum fording depth when its grab bucket is stood at the bottom equals excavation depth in water, therefore, this excavator can be transformed in the fish pond exploitation, the irrigation and water conservancy irrigation canals and ditches are transformed, and the lake embankment is reinforced, and river training etc. are than deepwater field work.
