Lifting equipment for building construction and lifting control method

Abstract

The invention provides lifting equipment for building construction and a lifting control method. The lifting equipment for the building construction and the lifting control method are characterized inthat the lifting equipment is provided a steel support structure, a cross beam structure moving on the steel support structure and a mobile lifting trolley moving on the cross beam structure; the cross beam structure comprises two main cross beam blocks and sliding supporting bodies located at both ends of the main cross beam blocks; and track protrusions are arranged on the upper end faces of the main cross beam blocks. The integral structure of the lifting equipment is redesigned, and the advantages of implementing the lifting equipment with the integral structure are that the building is easy, the integral lifting bearing capacity of the lifting equipment is higher, the automatic operation of the lifting equipment can be realized by remote control, and the energy consumption is low andeconomy is achieved.

Description

technical field [0001] The invention relates to a hoisting device in building construction, in particular to a hoisting device and a hoisting control method used in building construction. Background technique [0002] At present, bridge crane is a kind of common hoisting equipment, specifically a kind of bridge type crane that a kind of horizontal bridge is arranged on two supporting legs to form the gantry shape. This kind of crane can run on the ground track, and can be used for handling and installation in open storage yards, docks, power stations, ports and railway cargo stations, and can also be used in actual processing industries in factories; it is also Due to the wide range of uses of gantry cranes, improvements to gantry cranes have been made by those skilled in the art. [0003] After searching, it is found that the utility model of patent No. CN201220047899.9 discloses a crane, especially a single-girder gantry crane with V-shaped legs; it mainly solves the rela...

AI Technical Summary

Problems solved by technology

[0007] However, for these existing lifting devices, there are still the following deficiencies: one, the existing lifting devices usually use a motor to drive a single steel rope for lifting, so the lifting device of this structure has limited lifting capacity and relatively high energy consumption. high, it seems very uneconomical; second, because the existing steel rope is directly wound on the reel, the end of the steel rope is prone to loosening after long-term rolling; third, the existing lifting equipment is During the lifting process, the lifting position cannot be adjusted well, which is not conducive to the automatic operation of the lifting equipment; this will inevitably affect its operating efficiency
