Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 As shown, a foldable introduction mechanism includes an introduction beam I1, an introduction beam II2, and a support assembly. The introduction beam I1 is fixed below the special section 5, and one end of it is hinged to one end of the introduction beam II2. The support assembly is used for the introduction beam II2 Flat and folded support. Among them, the introduction beam I1 and the introduction beam II2 are a kind of H-shaped steel, they mainly play the role of slideway, and the introduction trolley is hung on the side of the two introduction beams, and the introduction trolley is used to send the standard section to be installed to the special in the space below section 5. The special section 5 is the transitional section between the standard section and the slewing bearing. It is a hollow frame support ...

Abstract

The invention discloses a foldable introducing mechanism. The foldable introducing mechanism comprises an introducing beam I, an introducing beam II and a supporting assembly, wherein the introducingbeam I is fixed below a special joint, one end of the introducing beam I is hinged to one end of the introducing beam II, and the supporting assembly is used for supporting the introducing beam II after the introducing beam II is flatly placed and folded. The supporting assembly comprises a pull rod I and a pull rod II, wherein one end of the pull rod I is fixed to the upper part of the special joint, the other end of the pull rod I is hinged to the introducing beam II, and the pull rod I is used for supporting the introducing beam II when the introducing beam II is flatly placed. One end of the pull rod II is fixed to the upper part of the special joint, the other end of the pull rod II is hinged to the introducing beam II, and the pull rod II is used for supporting the introducing beam II when the introducing beam II is folded. By adopting the structure, the travel of a lifting hook on a crane boom can be increased, and the maximum lifting weight can be increased.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a foldable introduction mechanism. Background technique [0002] The introduction mechanism of the tower crane is an important structure in the self-jacking installation process of the tower crane. When installing the tower crane, it is necessary to use the introduction mechanism to introduce the standard section into the climbing frame. The imported standard section and the lower standard section are installed with pins to achieve The purpose of raising the height of the tower crane is to speed up the installation process. In the prior art, the introduction mechanism adopted, because the introduction beam is integrated, the minimum working range of the hook on the boom is limited, and the maximum lifting capacity is reduced. At the same time, the actual installation requires a large space and is unstable. , it needs to move a lot in the installation space to install, which...
