Abstract
The invention provides a hydraulic bending telescopic crane. By the adoption of the hydraulic bending telescopic crane, the folding range of the crane is greatly widened, the total occupied area of the crane is decreased, the hydraulic bending telescopic crane can be better adaptive to small working spaces, and the overall applicability of the crane is improved. The hydraulic bending telescopic crane comprises a base. A supporting arm is arranged on the base. The hydraulic bending telescopic crane is characterized in that a first suspension arm is movably hinged to the supporting arm; a second suspension arm is movably hinged to the first suspension arm; a first supporting hydraulic cylinder is arranged on the first suspension arm; one end of the first supporting hydraulic cylinder is supported on the supporting arm; a second supporting hydraulic cylinder is arranged on the second suspension arm; and the second supporting hydraulic cylinder is connected with the first suspension arm.
Description
Technical field
The present invention relates to the technical field of hoisting machinery. It is specially a kind of hydraulic pressure bending telescopic crane.
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.
Summary of the invention
For the problems referred to above, the invention provides a kind of hydraulic pressure bending telescopic crane, improve the folded range of crane significantly, reduce the overall floor space of crane, be applicable to narrow and small work space better, improve the overall suitability of crane.
Its technical scheme is such that a kind of hydraulic pressure bending telescopic crane, it includes base, support arm is arranged on described base, it is characterized in that: the first arm is movably hinged described support 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 support arm, being provided with the second supporting cylinder on described second arm, described second supporting cylinder connects described first arm.
It is further characterized by described support arm and is rotatably connected with described base, forms turntable; Described second arm includes middle part connecting tube, and connecting tube two ends, described middle part are set with expansion link, and described middle part connecting tube 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, the described second hinged described projection end of support hydraulic pressure cylinder piston rod, forms the described second support hydraulic pressure cylinder piston rod eccentrically braces structure to described second arm.
In the described structure of the present invention, support arm is arranged on base, first arm is movably hinged support 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 and the first arm can rotate against, first supporting cylinder is supported on the first arm, first arm rotates around support arm, 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.
