Operation method for lifting wood

Abstract

The invention discloses an operation method for lifting wood, which comprises the following steps of: baling the wood with a steel wire; connecting the wood to be lifted with an automatic unhooking device through a rope by using a lifting hook of a crane, wherein an iron loop is additionally arranged between the loophole lifting hook in the automatic unhooking device and the eye splice of the steel wire, and the iron loop is sheathed on the loophole lifting hook; regulating the length of the rope under the loophole lifting hook to realize automatic unhooking; and completing lifting by starting the crane. The invention can obviously enhance the operational safety factor, thereby reducing the link with risk since the person unhooks in a high position in the wood operation; the invention can greatly enhance the operation efficiency, reduce the operation cost, increase the economic benefit, and enhance the operation efficiency by more than 30% as compared with the prior operation mode, thereby enhancing the workload in unit time and increasing the income; on the other hand, since the standby time of the equipment is reduced, the invention can indirectly reduce the energy consumption; and the invention can enhance the wood stacking rate per unit area.

Description

technical field [0001] The invention relates to a loading and unloading method, in particular to a timber hoisting operation method. Background technique [0002] Since the beginning of the new century, the overall scale of my country's logistics industry has grown rapidly, the service level has improved significantly, and the environment and conditions for development have continued to improve. However, the overall level of my country's logistics industry is still low, and there are still some outstanding problems. One of them is the logistics operation of the whole society. The efficiency is low, and the ratio of the total cost of social logistics to GDP is about 1 times higher than that of developed countries. Therefore, the port terminal industry, as an important part of the logistics industry, takes various effective measures to improve operating efficiency and reduce operating costs. The needs of fierce social competition are also the needs of actively integrating into t...

Problems solved by technology

[0003] Without the use of automatic decoupling device, there is a safety risk of high-level manual dehooking. When using automatic decoupling to lift timber, there are still disadvantages: (1) The wire rope hanging under the eye hook is too long, and the hook is too heavy to Automatic decoupling, too short hook and inconvenient; (2) After the pipa head of the wire rope is stressed many times, it is stretched and flattened, and the eye hook is clamped, and the decoupling is not smooth; Due to the pressure caused by the demand for the site, the stockpiling rate of wood per unit area must be increased. Therefore, the operation methods of wire rope bags and seaport cranes are used to stack the wood as high as possible. When the wood is stacked very high, this kind of operation is necessary The method requires operators to stand on unstable timber stacks to remove the hooks, which poses a great potential safety hazard
