Shipping system and method for wide and thick plates

Abstract

The invention discloses a shipping system for wide and thick plates. The system comprises: a sling used for hoisting and swinging wide and thick plates, wherein a permanent magnetic chuck is arranged on the sling and is provided with a chuck expansion device which adjusts expansion of the permanent magnetic chuck according to the length of the wide and thick plates; bar codes arranged on the wide and thick plates, wherein the bar codes are used for identification of identity and specification information of the wide and thick plates; a server in which the identity and specification information of the wide and thick plates is stored; a hand-held wireless terminal, wherein a bar code reader is arranged on the hand-held wireless terminal, and the hand-held wireless terminal is connected with the server; a port machinery wireless terminal which is connected with the hand-held wireless terminal through a wireless signal receiving and converting device; and a PLC which is connected with the port machinery wireless terminal, the sling and the permanent magnetic chuck and receives information sent by the port machinery wireless terminal to control hoisting and swinging motion of the sling and adsorption motion of the permanent magnetic chuck. Accordingly, the invention further discloses a shipping method for the wide and thick plates.

Description

technical field [0001] The invention relates to a transportation system and method, in particular to a metal plate shipment system and method. Background technique [0002] Wide and thick plates, also known as ship plates, are mainly used in the shipbuilding industry. They are large in size and heavy in weight. When they are transported to their destinations, they need to be loaded or unloaded with special handling equipment. At present, a kind of equipment for shipping wide and thick plates is a permanent magnetic suction cup spreader, which realizes the grasping, transportation and unloading of wide and thick plates through the generation and cancellation of magnetic force. [0003] The existing method of using permanent magnetic sucker spreader for wide and thick plates is as follows: figure 1 Shown: [0004] The cargo arrives at the dock; [0005] Operators visually inspect the specifications of wide and thick plates; [0006] The operator adjusts the magnetic force ...

AI Technical Summary

Problems solved by technology

[0016] 1. After the operator visually inspects the specifications of the wide and thick plates, he often selects the magnetic force of the permanent magnet spreader based on manual experience. Due to the influence of on-site environmental factors, the estimated information of the operator is prone to deviation. In actual operation, the selection of the spreader function often results in Errors occur on the surface, resulting in inability to adsorb, adsorption of two or more pieces of adhesion, etc. In this case, the operator needs to re-select the function of the spreader several times until the thick plate is absorbed, resulting in low work efficiency

In addition, the adsorption state is judged by human beings, and there may be cases where the wide and thick plates are not completely adsorbed, thus causing potential safety hazards

[0017] 2. Under weather conditions such as rain, snow, fog, etc., it is difficult for the operator to accurately judge the cargo information due to the influence of cargo and spreaders blocking the line of sight. At the same time, it is easy to collide with surrounding obstacles during the cargo hoisting process, resulting in cargo Quality accidents, or cause failure or damage to the permanent magnetic suction cup spreader

[0018] 3. In the actual operation process, the operator often lifts and operates the spreader while performing full magnetization in the pre-magnetized state. This operation method often causes wide and thick plates to be in a state where the wide and thick plates are not completely absorbed. come down

[0019] 4. It is difficult for the operator to accurately control the lifting speed during the lifting process of the wide and thick plate, resulting in the impact of the permanent magnet lifter on the wide and thick plate and the permanent magnet lifter body, resulting in the control board, relays, connecting wires, The looseness of electrical components such as the suction cup module causes the spreader to fail. At the same time, the spreader impacts the wide and thick plate to deform the wide and thick plate, resulting in quality problems
