Abstract

A kind of lifting device of crane, it includes the main arm of crane, dolly on main arm, described dolly, dolly is connected by telescopic arm with workbench, described workbench is mounted below rotatable turntable, described turntable is by fluid motor-driven, the joint of the first swing arm and the second swing arm group is mounted below in turntable, each section swing arm is by a fluid motor-driven, one manipulator is installed on nethermost swing arm, the present invention can be in some narrow spaces, and have dangerous place, and complete hoisting operation in the case of the dangerous situation of workpiece itself, due to the operating personnel that need not be aided in, also the expenditure of cost of labor is saved.

Description

A kind of lifting device of crane

Technical field

The present invention relates to crane, and in particular to crane hoisting apparatus, belong to crane technical field.

Background technology

It is well known that crane is in hoisting operation, cooperation can just complete lifting task jointly to generally require two people, I.e.:Driving driver and a hanging hook operating personnel, so there is human cost defect higher, meanwhile, stacked in some parts Place, due to narrow space and secure context, also lifting operation cannot be realized using the method for artificial hook, So, this can bring the inconvenience of many to production, and the operation of production cannot be even completed sometimes.

The content of the invention

It is an object of the invention to:For existing crane in operation process, existing human cost is higher, one Lifting cannot be completed in the case of a little narrow spaces and the dangerous place of tool and the dangerous situation of workpiece itself The defect of operation, the present invention provides a kind of new lifting device of crane, meets what above-mentioned particular place, specific workpiece were lifted by crane Need, meanwhile, also for the expenditure for saving cost of labor.

The present invention realizes that the technical scheme that above-mentioned purpose is used is:A kind of described lifting device of crane, it includes The main arm of crane, on main arm and can along main length of boom direction move dolly, below described dolly One slide plate is installed, the two ends of telescopic arm are connected between slide plate and workbench, described telescopic arm is the parallel of mutual concatenation Quadrilateral connecting rod mechanism, on the table face set a hydraulic cylinder, described hydraulic cylinder can control telescopic arm elongation or Shorten, a rotating shaft is fixed in the lower central position of workbench, rotating shaft is installed together by bearing with turntable, in rotation One gear ring of cylindrical upper installation of platform, installs a hydraulic motor on the table, and one is installed on described hydraulic motor axle Little gear, described little gear forms intermeshing relation with gear ring, installs one at the lower central position of turntable and hangs Ear, has first to open shelves in the middle of described hanger, the first hydraulic motor is fixed on the side of hanger, the first described hydraulic pressure Motor drive shaft is opened shelves through the first of hanger, and what the first retainingf key of the upper end of the first swing arm was arranged on hanger first opens shelves Between the first hydraulic motor axle on, the bottom of the first swing arm have with hanger open grade direction it is perpendicular second open shelves, Second hydraulic motor is fixed on second and opens shelves outside, and the second hydraulic motor axle is opened shelves through second, the second swing arm Upper end opened on the second hydraulic motor axle between shelves installed in second with the second retainingf key, the second swing arm bottom install One manipulator.

Beneficial effect:After the present invention is due to using the above method, manipulator can be any movable in space three-dimensional space, So, the present invention in some narrow spaces and can have dangerous place and the dangerous situation of workpiece itself In the case of complete hoisting operation, meet particular place, specific workpiece lift by crane the need for, simultaneously as the operation that need not be aided in Personnel, also save the expenditure of cost of labor.
