Problems solved by technology

The traditional portal-type lifting mechanism mainly adopts the "multi-component relay transmission mode" of "motor + coupling + reducer + drum". Due to the large number of transmission components in this structure, the transmission efficiency is low and the failure rate is high. Maintenance 1. The maintenance work is cumbersome and complicated; the overall volume is huge, and the space requirements for the machine room are relatively high; the overall weight is large, and the design load-bearing capacity of the installation and support parts is high.

Abstract

The invention relates to the technical field of port equipment, in particular to a permanent magnetic direct-drive gantry crane. The permanent magnetic direct-drive gantry crane comprises a gantry bracket, a walking mechanism is arranged on the lower portion of the gantry bracket, and a rotating platform is arranged on the upper portion of the gantry bracket, and provided with a cab, a machine room and a boom system. By using a permanent magnetic direct-drive motor, the total weight and the size of the crane are greatly reduced, and the manufacturing cost is saved; the transmission efficiency is improved, and meanwhile, the failure rate and the maintenance cost are reduced; the permanent magnetic direct-drive motor is quick in response, free of shaking and low in noise, and by means of the locked-rotor characteristic of the permanent magnetic direct-drive motor, a lifted object cannot stall and fall, so that safety is improved; and a planetary fan has a reversing function, and the wind direction faces the same direction no matter how the rotating direction of a permanent magnetic winding drum is, so that operators are prevented from being burnt due to frequent reversing of hot air.

Description

technical field [0001] The invention relates to the technical field of port equipment, in particular to a permanent magnet direct drive portal crane. Background technique [0002] Portal cranes are the main loading and unloading equipment in ports. There are thousands of portal cranes in domestic ports, which are the main equipment for port production. The traditional portal-type lifting mechanism mainly adopts the "multi-component relay transmission mode" of "motor + coupling + reducer + drum". Due to the large number of transmission components in this structure, the transmission efficiency is low and the failure rate is high. Maintenance 1. The maintenance work is cumbersome and complicated; the overall volume is huge, and the space requirements for the machine room are relatively high; the overall weight is large, and the design load-bearing capacity of the installation and support parts is high. Contents of the invention [0003] The purpose of the present invention i...
