The single-width slide rail of the bridge erecting machine cooperates with the multi-functional middle outrigger walking type lateral movement luffing mechanism

Abstract

The invention relates to the technical field of bridge construction, in particular to a single-width slide rail of a bridge-erecting machine combined with a multi-functional middle outrigger walking type traverse luffing mechanism, which mainly includes a first outrigger and a second outrigger connected to the bottom of the fuselage The legs, the first outrigger and the second outrigger are all composed of a support frame connected to the bottom of the fuselage, and the bottom of the support frame is fixedly connected with telescopic feet that expand and contract downward; it also includes a luffing beam, which is set horizontally for a section and a beam structure perpendicular to the length direction of the fuselage; the top of the luffing beam is matched to the area where the bottom of the support frame does not overlap with the telescopic feet through a horizontal sliding mechanism. The load on the two outriggers is carried alternately by the variable-amplitude beam and the telescopic foot, and the step-by-step walking mode is formed through the position change between the variable-amplitude beam and the telescopic foot, which realizes the lateral movement and variable amplitude function of the bridge erecting machine, and solves the problem of single-frame frame The bridge crane quickly completed the double-width segment assembly technology.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a single-width slide rail of a bridge-erecting machine combined with a multi-functional middle outrigger walking type traverse luffing mechanism. Background technique [0002] With the rapid development of my country's economy, the infrastructure has been continuously improved, and the road traffic network has become more and more perfect. Among them, bridges, as an important part of highways, have also been built in large numbers. In bridge construction, the application of double-width bridges has significantly improved traffic conditions, but there are still some shortcomings in the construction of double-width bridges. Among them, the bridge erecting machine used to erect bridge segments is usually used in single-width bridges In the erection scene, when it is necessary to build a double bridge, it is necessary to hoist the bridge erecting machine from the left si...

In bridge construction, the application of double-width bridges has significantly improved traffic conditions, but there are still some shortcomings in the construction of double-width bridges. Among them, the bridge erecting machine used to erect bridge segments is usually used in single-width bridges In the erection scene, when it is necessary to build a double bridge, it is necessary to hoist the bridge erecting machine from the left side of the bridge to the right side of the bridge, or reinstall the bridge erecting machine on the right side of the bridge. Since the bridge erecting machine is too large, this will lead to a long period of time and significant increase in cost
