Description
Technical field
The utility model relates to the technical field of elevator machinery.Be specially a kind of hydraulic pressure bending telescopic crane.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.Also known as crane.Belong to material carrying machine.The work characteristics of hoisting crane does intermittent exercise, i.e. feeding in a working cycle, migration, the corresponding mechanism of the actions such as unloading is alternation, hoisting crane development commercially and use more and more extensive, the particularly handling of large object, hoisting crane serves irreplaceable effect, jib-type crane is the class in numerous crane type, because the height of hoisting object is different, the hoisting crane practicality that length of boom is fixed is poor, what generally adopt is the hoisting crane of telescoping boom, in order to the entirety realizing hoisting crane is drawn in, usually folding folding arm telescopic crane is adopted now, existing its main support of folding arm telescopic crane is on main arm, arm and hold-down arm hinged, arm rotates around hold-down arm, achieve the gathering of arm, but the telescopic folding scope of this folding arm telescopic crane is less, thus the working area taken is larger, particularly narrow and small working space, hoisting crane cannot normally work.
Summary of the invention
For the problems referred to above, the utility model provides a kind of hydraulic pressure bending telescopic crane, improves the folded range of hoisting crane significantly, reduces the floor area of the entirety of hoisting crane, be applicable to narrow and small working space better, improve the overall applicability of hoisting crane.
Its technical scheme is such: a kind of hydraulic pressure bending telescopic crane, it comprises base, hold-down arm is arranged on described base, it is characterized in that: the first arm is movably hinged described hold-down arm, second arm is movably hinged described first arm, and described first arm is provided with the first supporting cylinder, and described first supporting cylinder one end is supported on described hold-down arm, described second arm is provided with the second supporting cylinder, and described second supporting cylinder connects described first arm.
It is further characterized in that: described hold-down arm is rotaryed connection with described base, forms rotating table; Described second arm comprises middle part connection pipe, and connection pipe two ends, described middle part are set with expansion link, and described middle part connection pipe is provided with double piston-rod cylinder, and the piston rod of described double piston-rod cylinder connects the described expansion link at two ends respectively; Described second arm one end is provided with projection end, and the hinged described projection end of described second support hydraulic pressure cylinder piston rod, forms described second support hydraulic pressure cylinder piston rod to the eccentrically braces structure of described second arm.
In described structure of the present utility model, hold-down arm is arranged on base, first arm is movably hinged hold-down arm, second arm is movably hinged the first arm, first arm is provided with the first supporting cylinder, second arm is provided with the second supporting cylinder, second supporting cylinder connects the first arm, owing to being provided with the first arm and the second arm, second arm can rotate relatively with the first arm, first supporting cylinder is supported on the first arm, first arm rotates around hold-down arm, achieve the double folding of arm, improve the folded range of hoisting crane significantly, reduce the floor area of the entirety of hoisting crane, be applicable to narrow and small working space better, improve the overall applicability of hoisting crane.
Accompanying drawing explanation
Fig. 1 is the utility model hydraulic pressure bending telescopic crane structural representation;
Fig. 2 is the utility model hydraulic pressure bending telescopic crane folded state schematic diagram.
Detailed description of the invention
See Fig. 1, a kind of hydraulic pressure bending telescopic crane, it comprises base 1, hold-down arm 2 is arranged on base 1, first arm 3 is movably hinged hold-down arm 2, second arm 4 is movably hinged the first arm 3, first arm 3 is provided with the first supporting cylinder 5, first supporting cylinder 5 one end is supported on hold-down arm 2, second arm 4 is provided with the second supporting cylinder 6, second supporting cylinder 6 connects the first arm 3, second arm 4 is provided with head coaster 11, by the first arm, second arm relatively folding, the entirety achieving hoisting crane is drawn in, improve the folded range of hoisting crane significantly, reduce the floor area of the entirety of hoisting crane, be applicable to narrow and small working space better, improve the overall applicability of hoisting crane.
Hold-down arm 2 is rotaryed connection with base 1, and form rotating table, hold-down arm 2 rotates around base together with whole arm, achieves moving radially of hoisting object.
Second arm 4 comprises middle part connection pipe 7, connection pipe 7 two ends, middle part are set with expansion link 8-1,8-2, middle part connection pipe 7 is provided with double piston-rod cylinder 9, the piston rod 10 of double piston-rod cylinder 9 connects expansion link 8-1, the 8-2 at two ends respectively, head coaster 11 is arranged on the expansion link 8-2 of one end, the piston rod 10 at double piston-rod cylinder 9 two ends moves, the expansion link 8-2 promoting middle part connection pipe 7 and one end stretches out, achieve the lengthening of arm, improve the applicability of hoisting crane, further improve the telescopic extensions of hoisting crane.
Second arm 4 one end is provided with the hinged projection end 11 of piston rod of projection end 11, second supporting cylinder 6, and the piston rod forming the second supporting cylinder 6, to the eccentrically braces structure of the second arm, improves the bearing force of arm.
