Problems solved by technology

[0002] The traditional installation method of heavy-duty bridge cranes is to use large-scale hydraulic cranes for single-machine hoisting or double-machine hoisting. When hoisting, the site is required to be flat and wide, which is convenient for the crane to stand, and the safety risk of hoisting is high; due to the heavy weight of the heavy-duty bridge crane parts, Longer booms and heights are required for hoisting, and even the roof structure needs to be removed to meet the hoisting requirements, which affects the installation progress of the plant structure
Since a large parking space is required for hoisting by a large hydraulic machine, the large equipment transported to the site cannot be placed in a centralized manner, and it is necessary to hoist one piece and unload one piece, which increases a lot of unloading work
The deployment and use of large-scale hoisting cranes, the unloading of equipment, and the demolition of roofs all require a lot of investment and increase costs.

Abstract

The invention discloses a stepped hoisting system and hoisting method for a heavy bridge crane. The stepped hoisting system comprises an advancing chassis, a retractable slope, stepped positioning structures and stepped lifting structures. The advancing chassis comprises driving advancing wheels and a slope containing cabin. The driving advancing wheels are arranged on the two sides of the advancing chassis in the equipment lifting direction. The plurality of stepped positioning structures are in one-to-one correspondence with the plurality of stepped lifting structures. The stepped lifting structures are movably connected to the top of the advancing chassis through the stepped positioning structures, and the placing distances of the stepped lifting structures can be adjusted through the stepped positioning structures. The stepped lifting structures can lift components such as a crane end beam and the like to an installation position in a staged mode. The stepped lifting structures canlift the components such as the crane end beam and the like to the installation position in a staged mode, so that the requirement on the operation space is low. Sliding friction is changed into rolling friction when the equipment components pass through an inclined guide plate through rolling balls, and the conveying difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a stepped hoisting system and hoisting method for heavy bridge cranes. Background technique [0002] The traditional installation method of heavy-duty bridge cranes is to use large-scale hydraulic cranes for single-machine hoisting or double-machine hoisting. When hoisting, the site is required to be flat and wide, which is convenient for the crane to stand, and the safety risk of hoisting is high; due to the heavy weight of the heavy-duty bridge crane parts, When lifting, a longer boom and height are required, and even the roof structure needs to be removed to meet the lifting requirements, which affects the installation progress of the plant structure. Since large-scale hydraulic machines are used for hoisting, a wide parking space is required, and the large equipment transported to the site cannot be placed in a centralized manner, and it is necessary to hoist one b...
