Abstract

The invention discloses a swing arm type underslung crane. The underslung crane comprises a cross beam, wherein a sliding seat is in clearance fit with the bottom of the cross beam, a balancing weightis arranged below the left side of a swing arm, an electric hoist is fixedly connected to the right side of the bottom of the swing arm, and a transmission assembly is arranged below the sliding seat. According to the swing arm type underslung crane, through threaded connection between a screw and the sliding seat and meshing connection between a driving wheel and driven wheels above, the slidingseat can drive the swing arm to transversely slide and axially rotate simultaneously, so that the hoisting range is expanded, and the use practicability and convenience are improved; the swing arm can transversely slide in a sleeve, then the swing arm is transversely prolonged, the application range is further expanded, and the use applicability is improved; and through clearance fit between a short rod and a rotating rod and corresponding arrangement of the rotating rod and the two driven wheels, the rotating rod can clamp the two driven wheels, then the swing orientation and the telescopinglength are limited, and the use stability and precision are further improved.

Description

technical field [0001] The invention relates to the technical field of swing-arm suspension cranes, in particular to a swing-arm suspension crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as cranes, aerial cranes, cranes, some of the lifting equipment is characterized by intermittent movement, that is, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately in a working cycle. [0003] When the swing arm type suspension crane in the prior art is in use, the swing arm cannot rotate axially while sliding laterally, thereby reducing the lifting range, reducing the practicability and convenience of use, and the swing arm cannot be extended laterally, further reducing the scope of use , reduce the applicability of use, and at the same time, the hook cannot be sealed, and the heavy objects are easy to acci...
