Problems solved by technology

[0002] Conventional segmental box girders are set up on a single line, and the bridge erecting machine is moved longitudinally one by one to construct the span. Hoisting to the right side of the bridge, or reinstalling the bridge erecting machine on the right side of the bridge, because the bridge erecting machine is too large, this will greatly increase the construction period and cost

Abstract

The invention discloses a traversing luffing method of a large-sized bridge erecting machine. The bridge erecting machine is slidably erected on a cross beam through middle supporting legs. The traversing luffing method comprises the following steps: 1, sliding the cross beam from the left side of a bridge to the right side of the bridge by using a steel rail. By the traversing luffing method, operation is convenient, the cost is low, the bridge erecting machine is not required to be hoisted, redetached and remounted, slippage of the cross beam in position in the case of no lifting equipment is achieved, and quick and convenient traversing luffing of the bridge erecting machine is achieved.

Description

Technical field [0001] The invention relates to the field of bridging machine edge width. More specifically, the present invention relates to a method for traverse luffing of a large bridge erecting machine. Background technique [0002] The conventional segment box girder is set up in a single line, and the bridge erecting machine is used to move the bridge erection facilities longitudinally. The technology is relatively complete. However, in actual construction, the double line box girder is often erected. At this time, the bridge erecting machine needs to be moved from the left side of the bridge. Hoisting to the right frame of the bridge, or re-installing the bridge erecting machine on the right frame of the bridge, because the bridge erecting machine is too large, this will cause the construction period and cost to increase greatly. Summary of the invention [0003] The invention provides a method for lateral movement and amplitude luffing of a large bridge erecting machine,...
