Hoisting tool and hoisting method for prefabricated grillage beam

Abstract

The invention relates to a hoisting tool for a prefabricated grillage beam. The hoisting tool for the prefabricated grillage beam is characterized in that the hoisting tool comprises a hoisting shaft and a hoisting plate; one end of the hoisting plate is fixedly connected with one end of the hoisting shaft, and the other end of the hoisting plate comprises a connecting hole. The invention further relates to a hoisting method for the prefabricated grillage beam. According to the hoisting method for the prefabricated grillage beam, the grillage beam is horizontally and obliquely hoisted to a dam body by means of the hoisting tool. According to the hoisting tool and the hoisting method for the prefabricated grillage beam, the novel hoisting tool is used for hoisting the prefabricated grillage beam, and the problems that in the prior art, a steel wire rope is used for binding the grillage beam, the bound grillage beam is difficult to hoist, the steel wire rope is difficult to untie, and the construction efficiency is low are solved; in addition, the hoisting tool can be used for hoisting and can also be used for oblique hoisting, so that on-site slope protection construction is convenient and rapid, and accordingly the slope protection construction efficiency is greatly improved; furthermore, the safety of slope protection construction is greatly improved.

Description

technical field [0001] The invention relates to a hoisting tool and a method for hoisting an object by using the hoisting tool, in particular to a hoisting tool and a hoisting method for a prefabricated grid beam used for ecological slope protection on a dam body. Background technique [0002] With the rapid development of my country's economy, during the construction of highways, railways, water conservancy, electric power, mines and other projects, there are often a large number of excavation and filling, forming a large number of exposed slopes, which destroy the ecological balance of nature , has brought a series of environmental problems, such as soil erosion, landslides, debris flows, local microclimate changes, and biological chain damage. Therefore, it is very necessary to take engineering measures for protection and artificial greening to restore vegetation and ecological functions, reduce disasters and protect the environment. [0003] There are various slope prote...

Problems solved by technology

However, in actual construction, because prefabricated grid beams are usually large in size and heavy in weight, conventional hoisting methods are adopted during the process of transporting and installing them on the slope, that is, using steel wire ropes to pass through the prefabricated grid beams The four sides of the grid must be taken out after hoisting in place. Due to the heavy weight of the hoisting object, about ten people are required to cooperate, and the ground where the grid beam is installed must be leveled again. The steel wire rope is not easy to take out during the trial lifting process. If the steel wire rope is used to pass through the assembly hole, the diameter of the steel wire rope needs to be reduced, which will cause unsafe factors for the hoisting work. There is a certain slope, so the grid beam hanger must also be hung obliquely, which adds a certain degree of difficulty and requires additional manpower to assist and adjust the direction during the hoisting process, thereby reducing the efficiency of hoisting again
