Steel tube cargo shipping accessory and operating method employing same

Abstract

The invention provides a steel tube cargo shipping accessory. A supporting bar of the accessory is hung on the shackle of a supporting bar suspension system; a short suspension system is hung on the suspension centre at the lower part of the supporting bar; two ends of a chain are hung on the shackles of the short suspension system; a slip hook is hung on the chain in a sliding manner; a steel wire lock catch is connected onto the chain through the slip hook; meanwhile, the invention provides an operating method employing the steel tube cargo shipping accessory. The steel tube cargo shipping accessory and the operating method employing the same have the benefits that after cargos are lifted and suspended in the air, stability during the process of operation is guaranteed by employing the method, the problem that the peripheral perimeters of the cargos in each car of a pallet truck are unequal due to unequal diameters of steel tube cargos is solved, the accessory is applied to steel tube cargos with wide specification ranges, time for changing tools due to specification change of the cargos is reduced, the potential safety hazards are reduced, the working performance is improved, the operation is convenient, and the accessory has remarkable application effects at a general cargo terminal which regards 25 tonne portal cranes as main operation machinery.

Description

technical field [0001] The invention belongs to a steel pipe cargo shipping attachment and an operation method using the same. It involves a steel pipe cargo loading operation method with a steel pipe diameter ranging from 12.7mm to 152.4mm and a length of 6 meters. Background technique [0002] The port loading operation process includes dismantling and loading trailers on land. Each truck is loaded with two sections, and each section is controlled at close to 20 tons. The trailer transports the cargo horizontally to the side of the ship, where the portal crane or the ship's own ship's engine is used to hoist it into the cabin to complete the loading process. [0003] At present, most of the portal crane models are 25T-40M, with a maximum lifting capacity of 25 tons, a variable amplitude range of 12 meters to 40 meters, 360-degree rotation, and self-propelled along the track. [0004] Such as figure 1 , 2 As shown, the following process scheme was adopted in the origina...

AI Technical Summary

Problems solved by technology

[0011] ①The surface of the galvanized welded pipe has a galvanized layer. Since the eye of the 20-ton hook wire buckle has an end ring, the owner proposed that the cargo will be damaged when the hook wire buckle is pulled out during loading of the galvanized welded pipe.

In addition, during the process of buckling in the cabin, the hook nose (eye part) of the hook hook hanging on the hook head of the double hook is easy to detach, which poses a great potential safety hazard

[0012] ②The diameter of the 20-ton hook thread button is relatively thick, and the labor intensity of the loading and unloading personnel during the hooking operation is relatively high. At the same time, the button damage frequency is high and the cost is high.

[0013] ③Because it is necessary to lower the curved hole hook on the hook thread buckle to a position suitable for hooking when hooking, the technical requirements for door operator drivers and conductors are relatively high, and it is difficult for a novice to be competent

[0014] ④ When lifting the pallets, the support bars on both sides of the pallet truck will cause great damage to the cargo
