Double-hook crane slewing trolley

Abstract

The invention relates to a double-hook crane slewing trolley. The double-hook crane slewing trolley comprises a slewing trolley body, wherein the left side of the slewing trolley body is equipped witha worm; one end of the worm is connected with a variable-frequency motor; the right side of the worm is equipped with a rotary table; the outer side of the rotary table is equipped with a gear ring;the inner side of the gear ring is equipped with a rotary ring; a supporting plate is arranged on the rotary ring; a lifting mechanism is arranged above the supporting plate; the lifting mechanism consists of coiling blocks and an electric motor; a fixed rod is arranged above the coiling blocks; the electric motor is arranged at the right sides of the coiling blocks; the left side of the electricmotor is connected with main transmission shafts; left and right coiling blocks are arranged on the main transmission shafts; the middle part below the left supporting plate is connected with a rotaryshaft; and a small motor is connected below the rotary shaft. The double-hook crane slewing trolley has the advantages of being stable and accurate in rotation, safe and reliable, and flexible in use.

Description

technical field [0001] The invention belongs to the technical field of cranes, and in particular relates to a double-hook crane slewing trolley. Background technique [0002] Ordinary cranes run horizontally on the track on the main girder to realize the transfer of goods, but they cannot rotate, which limits the direction of the reel to hang the goods. It is necessary to move the goods first for the hook to hang, which is inconvenient to use. And all are single suspension hook, and its hoisting weight is light, and scope of application is limited; Therefore, need a kind of double suspension hook crane rotary trolley. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a double-hook crane slewing trolley with stable and accurate rotation, safety and reliability, and flexible use. [0004] The object of the present invention is achieved in the following way: a double-hook crane slewing trolle...
