Prestress carbon fiber aerial ladder truck cantilever crane

Abstract

A prestress carbon fiber aerial ladder truck cantilever crane mainly comprises vertical ladder columns, ladder steps, struts and lateral oblique beams, wherein the vertical ladder columns are connected with the lateral oblique beams; the lateral oblique beams are connected with the struts; the struts have the load-bearing effect; the left strut and the right strut are connected with each other by the ladder steps; and a worker can walk on the cantilever crane through the ladder steps. The structural style of cross sections of the struts is improved, carbon fiber materials are pretreated so that the carbon fiber materials have the prestress effect, and then the prestressed carbon fiber materials are connected with the struts of the cantilever crane. The invention provides an aerial ladder truck firefighting cantilever crane structure, the cross sections of the struts of the cantilever crane have novel C-shaped structures, and two sections of the cantilever crane are combined in an inserted mode. In addition, the carbon fiber materials are tensioned in advance, the cross sections of the struts of the cantilever crane have the novel C-shaped structures, and inner lower sides of the struts and the prestressed carbon fiber materials are anchored. The novel cantilever crane is subjected to a reverse prestress effect when not working; stress and deformation conditions of the cantilever crane can be improved effectively when the cantilever crane works, and therefore, the prestress carbon fiber aerial ladder truck cantilever crane is high in efficiency, good in performance and high in safety.

Description

technical field [0001] The invention relates to the field of special vehicles, in particular to a structural scheme design of a prestressed carbon fiber material aerial ladder vehicle arm frame. Background technique [0002] In recent years, with the rapid economic development in mainland China, the number of high-rise buildings has expanded rapidly, and the height of buildings has become higher and higher, which has greatly increased the difficulty of rescue. Therefore, in terms of urban firefighting and dangerous rescue, aerial ladder vehicles are the most efficient rescue method. . The most recognized part of the aerial ladder fire truck is the boom telescopic structure. The design optimization and manufacturing level of the boom structure determine the high-tech content of the aerial ladder truck. The jib structure of the aerial ladder truck needs to bear a lot of loads, including the gravity of the ladder frame, the load of the wind, the gravity of the working bucket,...

AI Technical Summary

Problems solved by technology

These gaps are mainly reflected in: the overall working height of the aerial ladder fire truck is not high, the lightweight research of the vehicle has not been realized, the research on the intelligent control setting is not deep enough, and the stability and safety of the vehicle cannot be guaranteed under extreme conditions. Parts supporting level and manufacturing level are not high
