specific Embodiment approach

[0061] Furthermore, as a specific embodiment of the steel beam hoisting method provided by the present invention, the lateral adjustment tool is a crowbar.

[0062] according to Figure 3 to Figure 8 , define the first side as the left side, the second side as the right side, the first end as the left end, and the second end as the right end. The specific usage process can be:

[0063] 1) The two ends of the steel beam 3 are respectively connected to the suspension rings 57 located on both sides inside the silo main body 1;

[0064] 2) Lift the left end of the steel beam 3 through the lifting ring 57 located on the left side of the silo main body 1, so that the left end of the steel beam 3 is higher than the right end of the steel beam 3, and the long axis of the steel beam 3 forms an acute angle α with the ground;

[0065] 3) Synchronously lift the left end and right end of the steel beam 3 through the lifting ring 57 on the left side of the silo main body 1 and the lifting ...

Abstract

The invention provides a flexible sliding film platform steel beam hoisting device. The flexible sliding film platform steel beam hoisting device comprises at least two main brackets which are symmetrically arranged at the upper part of a silo main body, at least two pulley lifting mechanisms which are symmetrically arranged in the silo main body and are connected with the main body bracket, at least two counterweight mechanisms which are symmetrically arranged on the outer side of the silo main body and are connected with the main brackets, and a translation mechanism which is connected with the pulley lifting mechanisms and is used for enabling steel beams to transversely move. According to the flexible sliding film platform steel beam hoisting device provided by the invention, the entire structure is simple, hoisting utilization is convenient, reliability is high, the relative height of the two ends of the steel beams can be flexibly adjusted, the transverse positions can be flexibly changed, the steel beams can be quickly hoisted in place from the interior of the silo main body, and hoisting efficiency is effectively improved. The invention further provides a steel beam hoisting method. The hoisting process is stable, hoisting efficiency is high, hoisting difficulty can be reduced to a quite large extent, and construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and more specifically relates to a flexible sliding form platform steel girder lifting device and a steel girder lifting method. Background technique [0002] The chemical industry is developing rapidly, and the construction of chemical production plants is also increasing rapidly. In the process of building a chemical plant, the slipform construction cylinder is a very important structure, and its manufacturing process is constantly improving, especially the flexible slipform platform is the most widely used. In the construction process of the existing flexible sliding form platform, due to the need to hoist the steel beam structure, the weight of the steel beam is heavy and the hoisting is difficult. Since the length of the steel beam is greater than the inner diameter of the silo body, the conventional hoisting method is often from the silo body. External plug-in hoisting often ...
