Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the invention in a schematic manner, and therefore only show the configurations related to the present invention.

[0027] As shown in the figure, the present invention is a plate-reinforced telescopic lattice boom structure, which can be used for the topmost sections of telescopic booms of all-terrain cranes, as well as the jib of all-terrain cranes and crawler cranes. Taking the first section of the telescopic boom 1 as an example, the structure of the crane telescopic boom structure reinforced with a truss structure is as follows: the peripheral structure is a truss rod 5, and a reinforcing plate 4, a middle reinforcing plate 6 and The top reinforcing plate 8 is welded with the web 7 in the rest, and the pin hole 9 is set at the 0 position of the truss corresponding to the bot...

Abstract

The invention provides a plate enhanced telescopic truss arm structure, and relates to the field of engineering machinery. The plate enhanced telescopic truss arm structure is characterized in that plates are welded in a truss structure, so that a crane telescopic arm structure for enhancing the truss structure is formed. The plate enhanced telescopic truss arm structure can be utilized in severalsections of telescopic arms of the topmost end of an all-terrain crane and conventional combined sub arms of the all-terrain crane and a crawler crane, the plates are welded in the truss structure, the advantage that the effect of wind load on the truss structure is small is reserved, strength of the root part of the sub arm of the crane can be strengthened, the arm rising condition of the craneis improved, and the problem that the truss telescopic arm needs to be disassembled and assembled at any time and cannot quickly extend and retract is solved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a telescopic arm structure for reinforcing a truss with a plate. technical background [0002] Due to the light weight of the truss, small windward area, and large bearing capacity, the jib of the truss structure has been widely used in construction machinery. At present, on some construction machinery, the lattice arm needs to change the length of the lattice arm according to the actual working conditions. The usual method is to remove a section of the boom section from the lattice arm or add a section to the lattice arm. This method is cumbersome to operate and is not conducive to It saves manpower and time. Moreover, concentrated stress will be generated at the nodes in the truss structure, which makes the mechanical performance of the truss structure itself poor. [0003] The main component of the boom is the telescopic boom, which consists of a number of seque...
