Description

Pallet truck steel coil transportation system and pallet steel coil transportation system linking device

Technical Field

The invention belongs to the technical field of steel coil transportation, and particularly relates to a device for connecting a steel coil transportation system of a pallet truck with a steel coil transportation system of a pallet truck.

Background

For more than 10 years, the steel coil transportation of metallurgical enterprises, especially the steel coil transportation of newly-built hot rolling factories, basically adopts a tray type transportation scheme, wherein the scheme is divided into two types, namely double-layer tray transportation and double-row tray transportation. The tray transportation system of the horsesteel 2250mm hot rolling mill is a first double-layer tray transportation system in the world, the tray transportation system of the first steel Jingtang 2250mm hot rolling mill is a first double-row tray transportation system in the world, and the double-row tray transportation technology has more obvious advantages than a double-layer tray transportation technology. Although the pallet-type transportation technology meets the production requirement of the modern hot rolling mill at a fast pace, the following defects also exist: the road trafficability is poor, and underground tunnels or elevated frames are generally needed when the road is crossed; the longer the transport distance is, the more the motors and sensors are needed, so that the workload of cable laying is large, and the running reliability of equipment is reduced; the civil engineering construction workload is large, the precision requirement of equipment installation is high, and the construction period is long.

In order to solve the limitation of the pallet transportation, the first steel international engineering company develops the first new-energy intelligent pallet truck steel coil transportation system with completely independent intellectual property in the world in recent years, and compared with the pallet transportation system, the system has more application advantages and innovativeness: the pure super capacitor is adopted for power supply, braking energy can be recovered, the whole life cycle is pollution-free, and the method conforms to the concepts of green, environmental protection, low carbon and energy conservation; the limit of the traditional power supply mode is overcome, the transportation equipment gets rid of the dependence on cables, a large number of cables can be saved, the construction scheme is simplified, the engineering investment is reduced, and the operation cost is reduced; the transportation cost is greatly reduced by adopting rail transportation, the road trafficability is good, and the transportation can be crossed with social roads; and by adopting wireless communication, the radiation of a control cable is reduced, and the automation degree is high. The new-energy intelligent pallet truck steel coil transportation system can completely replace walking beams, quick chains and pallet steel coil transportation systems.

At present, a plurality of production lines all adopt a tray steel coil transportation system, the passing performance of the tray steel coil transportation system is poor when the tray steel coil transportation system passes through a road, and the tray steel coil transportation system generally adopts the combination of tray steel coil transportation and automobile transportation to complete the steel coil transportation task of a production line and a workshop steel coil warehouse. The transportation cost is high and the environment is polluted by adopting the automobile. The technical problem that the technical personnel in the field need to solve at present is how to finish the steel coil transportation tasks of the production line, the steel coil warehouse and the steel coil warehouse in a workshop by means of the new energy intelligent pallet truck steel coil transportation system by adopting the pallet steel coil transportation system for the steel coil transportation system of the original production line.
