Hoisting device and hoisting method

Abstract

The invention discloses a hoisting device and a hoisting method. The hoisting device comprises a body, a first hoisting lug group and a second hoisting lug group, and the first hoisting lug group is arranged on the upper end surface of the body and is used for being matched with hoisting hooks of more than two bridge cranes on a hoisting station; and the second hoisting lug group is arranged on the lower end face of the body and used for being matched with a hoisting point of a to-be-hoisted part so that the to-be-hoisted part can be vertically hoisted. The hoisting device can enable more than two bridge cranes to participate in hoisting at the same time, so that the hoisting tonnage of the cranes is increased; and in addition, the function of transferring the bridge cranes and the to-be-hoisted part is achieved, the hoisting hooks with the fixed positions of the bridge cranes is converted into a hoisting point matched with the to-be-hoisted part, the problem that the lifting point position of the to-be-hoisted part cannot meet the hoisting standard of two or more cranes is solved, under the limited hoisting condition on a hoisting station, the reliable and safe hoisting operation on large parts is completed, the application range of the bridge cranes in a construction site or a factory is enlarged, and the hoisting time is saved.

Description

technical field [0001] The invention relates to the technical field of slings, and more specifically, to a hoisting device. In addition, the present invention also relates to a hoisting method applied to the above-mentioned hoisting device. Background technique [0002] For large-scale machinery, such as roadheaders, the weight and outline size of the component assembly are relatively large. Therefore, it is necessary to use lifting equipment such as bridge cranes to hoist the overweight and oversized component assembly during the assembly process . [0003] However, since the lifting tonnage, the minimum distance between the double hooks and the minimum distance between the cranes of the bridge cranes currently used in the manufacturing workshop or construction site have been fixed, the size and weight of different parts often vary greatly due to different product models. Therefore, in some cases, only relying on the bridge crane equipped on the station cannot be hoisted ...

Problems solved by technology

[0003] However, since the lifting tonnage, the minimum distance between the double hooks and the minimum distance between the cranes of the bridge cranes currently used in the manufacturing workshop or construction site have been fixed, the size and weight of different parts often vary greatly due to different product models. Therefore, in some cases, only relying on the bridge crane equipped on the station cannot be hoisted safely, and there will be problems such as insufficient crane tonnage, and the position of the lifting point of the parts does not meet the hoisting specifications of double cranes.
