Problems solved by technology

[0002] In some inspection and maintenance equipment, due to the high foundation of the equipment, many obstacles around, the site is narrow, the crane station is limited, and there are few large-scale cranes available on the construction site and surrounding areas, the existing cranes are used for joint hoisting, such as a single machine The main crane, double-machine lifting crane, single-machine or double-machine sliding tail crane cannot complete the hoisting operation, so the above-mentioned equipment puts forward new technical requirements for hoisting technology

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] The present invention proposes an eccentric hoisting method in cooperation with a crane and a hoisting frame. The method includes the following steps:

[0024] The first step is to make the lifting frame. According to the hoisting capacity of the crane, carry out the load sharing calculation, determine the positions of the main hoisting point and the tail hoisting point, calculate the hoisting capacity of the hoisting frame, and design the hoisting frame.

[0025] The second step is to set up the lifting frame. A pair of lifting frames are respectively erected near the equipment installation foundation, and the two lifting frames are arranged symmetrically with respect to the center of the equipment installation foundation; the lifting frame is designed according to the mast principle: the top of the lifting frame is equipped with a main hoist block, and the ma...

Abstract

The invention relates to a hoisting method, in particular to a method for realizing eccentric hoisting by matching a crane and a hoisting frame. In the method, the crane is matched with the hoisting frame to eccentrically hoist equipment; during the state variation of the equipment from a horizontal state to a vertical state, the hoisting frame plays a role in tailing and hoisting; and when the equipment is erected to be in position, the hoisting frame plays a role in hoisting. The method of the invention can be used in work environments of high equipment foundation, a plurality of surrounding barriers and difficult crane positioning, and has the advantages of safe and stable hoisting process and economic hoisting cost.

Description

technical field [0001] The invention relates to a hoisting method, in particular to an eccentric hoisting method with a crane and a hoisting frame. Background technique [0002] In some inspection and maintenance equipment, due to the high foundation of the equipment, many obstacles around, the site is narrow, the crane station is limited, and there are few large-scale cranes available on the construction site and surrounding areas, the existing cranes are used for joint hoisting, such as a single machine The main crane, double-machine lifting crane, single-machine or double-machine sliding tail crane cannot complete the hoisting operation, so the above-mentioned equipment puts forward new technical requirements for the hoisting technology. Contents of the invention [0003] The object of the present invention is to propose an eccentric hoisting method with a crane and a hoisting frame. The method can be used in a working environment where the equipment foundation is high,...
