Abstract

The invention discloses a lifting method of a pile frame and relates to the technical field of hoisting equipment; the lower end of the pile frame is hinged with the lower end of an A-shaped frame, the hinged point is defined as a lower hinge point, the upper end of the pile frame is lifted by the the hoisting equipment; after the pile frame rotates around the lower hinged point to form an included angle Alpha with a horizontal plane, the pile frame is pulled by a winch to continuously rotate around the lower hinged point to form an included angle Beta with the horizontal plane, and Alpha is less than Beta. According to the invention, the lower end of the pile frame is hinged the lower end of the A-shaped frame firstly, and then the initial hoisting is completed by using the hoisting equipment until the included angle between the pile frame and the horizontal plane is Alpha; as the hoisting height of the hoisting equipment is not enough, the pile frame is pull ed to rotate by a winch traction rope until the included angle between the pile frame and the horizontal plane is Beta, and finally the pile frame can be adjusted by using a chain hoist. The lifting method provided by the invention can complete the hoisting of the pile frame under the condition that the hoisting height of the existing hoisting equipment is insufficient without renting other large hoisting equipment; the approach time of other hoisting equipment is reduced; the lifting method provided by the invention has low cost, high efficiency and time saving.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a pile frame hoisting method. Background technique [0002] At present, most of the hoisting operations are hoisting operations performed by lifting equipment alone, such as using gantry cranes or portal cranes to lift large equipment and sections. If the lifting weight exceeds the lifting capacity of a single lifting device, use two or more lifting devices for joint lifting. [0003] However, if the lifting height exceeds the lifting height of the lifting equipment, such as the pile frame of the DCM ship, it is usually necessary to rent external lifting equipment for lifting, such as floating cranes, crawler cranes, and truck cranes. However, the rental of these equipment The cost is high, and it requires a certain amount of time to enter the site and occupies the site in the factory, which will undoubtedly increase the equipment rental cost, time cost and management...
