Abstract
The invention provides a crane boom connecting structure which greatly improves the folding range of a crane, reduces the occupied area of the crane, is better applied to narrow working space, improves the overall applicability of the crane, and meanwhile reduces a supporting force for a boom. The crane boom connecting structure is characterized by comprising a first boom and a second boom, wherein the second boom is provided with a lug end; the first boom is hinged to a hydraulic cylinder; and the piston rod of the hydraulic cylinder is in hinged connection with the lug end to form a hydraulic cylinder-piston rod eccentric support structure.
Description
Technical field
The present invention relates to the technical field of hoisting machinery parts. It is specially a kind of crane arm attachment structure.
Background technology
Crane refers to many actions hoisting 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 crane is to do intermittent exercise, i.e. feeding in a cycle of operation, migration, the corresponding mechanism of the actions such as unloading is alternation, crane development commercially and use more and more extensive, the particularly handling of big part object, crane serves irreplaceable effect, jib-type crane is the class in numerous crane type, owing to the height of hoisting object is different, the crane practicality that length of boom is fixed is poor, commonly used is the crane of telescoping boom, in order to realize the overall gathering of crane, generally adopt folding folding arm telescopic crane now, existing its main support of folding arm telescopic crane is on main arm, arm is hinged with support arm, arm rotates around support arm, achieve the gathering of arm, but the telescopic folding scope of this folding arm telescopic crane is less, thus the work area taken is bigger, particularly narrow and small work space, crane cannot normal operation, and the support force of arm is bigger.
Summary of the invention
For the problems referred to above, the invention provides a kind of crane arm attachment structure, improve the folded range of crane significantly, reduce the overall floor space of crane, it is applicable to narrow and small work space better, improve the overall suitability of crane, reduce the support force of arm simultaneously.
Its technical scheme is such that a kind of crane arm attachment structure, it is characterized in that: it includes the first arm and the second arm, described second arm arranges projection end, described first arm is hinged with hydraulic cylinder, described hydraulic cylinder piston rod is articulated and connected described projection end, forms hydraulic cylinder piston rod eccentrically braces structure.
It is further characterized by described projection end to be provided with two pin joints, and described first arm is articulated and connected one of them pin joint, and described hydraulic cylinder piston rod is articulated and connected another one pin joint.
In the described structure of the present invention, crane arm includes the first arm and the second arm, second arm arranges projection end, first arm is hinged with hydraulic cylinder, hydraulic cylinder piston rod is articulated and connected projection end, form hydraulic cylinder piston rod eccentrically braces structure, owing to arm includes two arms being articulated and connected, achieve the double folding of arm, improve the folded range of crane significantly, reduce the overall floor space of crane, it is applicable to narrow and small work space better, improve the overall suitability of crane, hydraulic cylinder piston pole pair projection end forms accentric support simultaneously, reduce the support force of arm.
Accompanying drawing explanation
Fig. 1 is crane arm attachment structure schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1,
A kind of crane arm attachment structure, it includes the first arm 1 and the second arm 2, second arm 2 arranges projection end 3, first arm 1 is hinged with hydraulic cylinder 4, projection end 3 is provided with two pin joint 3-1, 3-2, first arm 1 is articulated and connected one of them pin joint 3-1 on projection end 3, hydraulic cylinder piston rod 5 is articulated and connected another pin joint 3-2 on projection end 3, form hydraulic cylinder piston rod eccentrically braces structure, owing to arm includes two arms being articulated and connected, achieve the double folding of arm, improve the folded range of crane significantly, reduce the overall floor space of crane, it is applicable to narrow and small work space better, improve the overall suitability of crane, hydraulic cylinder piston pole pair projection end forms accentric support simultaneously, reduce the support force of arm.
