Conversion device for ultra-long cable of port machinery in pod operation

Abstract

The invention discloses a conversion device for a super-long cable of a cabin hoisting operation port machine. The device comprises an inversion power supply system, wherein the inversion power supplysystem is arranged on a port machine hanging beam and comprises a battery pack G, an inverter A1, a transformer D01, a remote controller receiver A2, a relay and a relay switch; the output end of theinverter A1 outputs high-voltage alternating current, the output of the inverter A1 is divided into two paths, one path of the output is led to a power supply control system, and the other path of the output is connected with the relay switch and a hook motor M3. The conversion device adopts the inversion power supply system to replace an existing mode of supplying power through a super-long cable to drive the hook motor during cabin hoisting operation, so that the operation of the port machine is not influenced under a severe weather condition. When the port machine works on a wharf surface,instead of adopting an existing working mode that the cable is electrified to drive the hook motor, the inversion power supply system is charged to ensure the electric quantity requirement during cabin operation, and therefore, the safe and efficient operation of the cabin hoisting operation port machine is ensured.

Description

Technical field [0001] The invention relates to a port machinery cable device, in particular to a port machinery ultra-long cable conversion device during pod operation. Background technique [0002] At present, the large port cranes in use in the finished product wharf of an enterprise are mostly used for loading and unloading of finished steel coils, steel plates and other goods. The port cranes have stable performance, large tonnage of loaded goods and high operation efficiency. They are the main operating equipment of the wharf. . The port machinery is mainly composed of trolley 12, beam, trolley, machinery room, electrical room, crane beam (including hook), cab 3 and other institutions. The trolley includes trolley wheels 1, trolley rail 2, and the trolley is equipped with protection The cover 13, the cable bracket 15, and the cable bracket 15 can hold the cable 14. The lifting beam 6 and the hook 5 are the main units for lifting, loading and unloading goods, and the work l...

AI Technical Summary

Problems solved by technology

In addition, when the crane beam of the port machine shakes greatly, the cables will escape out of the cable storage basket and become entangled with the mechanical mechanism, causing the cables to be broken. The cables are 380V high-voltage electricity, and the charged high-voltage cables It is extremely dangerous after being broken. Whether it touches the operating equipment or personnel, it will have serious consequences. It will not only cause damage to the electrical components of the equipment, but also increase the investment in equipment maintenance costs, and there is a great potential safety hazard for people.

[0006] Due to the suspension of port machinery operations, it will seriously affect the factory efficiency of finished goods, and it will also have a greater impact on the logistics system of the enterprise.

There has been no good solution to the problem of cable damage in bad weather
