Problems solved by technology
However, the folding limit device of the pull plate of the existing crane can only be folded at the predetermined hinge point, and the pull plate of the telescopic arm structure cannot be used when the pull plate is folded, and it is also impossible to realize the folding of the pull plate on different surfaces at the upper and lower hinge points.
[0005] It can be seen that the limit function of the pull plate is very limited by the existing folding limit device of the pull plate of the crane, which is inconvenient for construction and low in efficiency

The invention discloses a pulling plate guiding and folding apparatus, a pulling plate mechanism and a crane. The pulling plate guiding and folding apparatus is arranged between an upper guiding pulling plate and a lower guiding pulling plate of the crane and comprises a guiding plate, spacing mechanisms and an elastic driving device, wherein the first end of the guiding plate is connected with the lower end of the upper guiding pulling plate, the second end of the guiding plate is connected with the upper end of the lower guiding pulling plate, the spacing mechanisms are respectively arranged on the coupling end of the upper guiding pulling plate and the guiding plate and on the coupling end of the lower guiding pulling plate and the guiding plate and used for limiting the rotation angle of the guiding plate, one end of the elastic driving device is connected with the guiding plate, the other end of the elastic driving device is connected with the upper guiding pulling plate or the lower guiding pulling plate, and the elastic driving device is used for driving the guiding plate to rotate. Thus, the pulling plate guiding and folding apparatus provided by the invention can control automatic and ordered folding of foldable pulling plates.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a pull plate guiding and folding device, a pull plate mechanism and a crane. Background technique [0002] With the enlargement of the crane, the jib has become one of the indispensable parts, and the pull plate has become the stress member connecting the jib bracket and the jib. The multi-section pull plates are hinged together through pin shafts. During the boom raising process, the pull plates are opened and can freely rotate around the pin shafts in the luffing plane. During the arm drop process, the pull plate is folded and put away, so the pull plate is increasingly widely used due to its excellent performance of convenient stacking and reliable force. [0003] In order to save space and facilitate transportation, it is usually required that the pull plates can be stacked neatly at the predetermined position. Due to the diverse rotation of the multi-section pull plates...
