Problems solved by technology

However, sometimes these construction machines using articulated connection frames need to work in a rough site environment. When moving up and down slopes, because the rear frame cannot move up and down relative to the front frame, it is easy to cause the rear frame to Collision and interference with other front parts

Abstract

The invention discloses a pin shaft connection frame, which comprises a connection frame, a transition frame and a reversing frame which are hinged in sequence from front to back, wherein the connection frame can rotate left and right relative to the transition frame; and the reversing frame can rotate up and down relative to the transition frame. The pin shaft connection frame provided by the invention realizes the left and right and up and down rotation of the connection frame, so that the phenomena of mutual collision and interference between the reversing frame and other components during the up and down movement of an engineering machine using the connection frame are avoided.

Description

technical field [0001] The invention relates to a connecting frame, in particular to a pin shaft connecting frame. Background technique [0002] Construction machinery (such as roadheaders) using articulated connecting frames generally achieve left and right steering through the relative rotation of the front and rear frames, and the front and rear frames are usually connected by pins or rotary discs. However, sometimes these construction machines using articulated connection frames need to work in rough site environments. When climbing up and down slopes, because the rear frame cannot move up and down relative to the front frame, it is easy to cause the rear frame to Collide with other front components and interfere with each other. Contents of the invention [0003] The object of the present invention is to provide a pin-shaft connection frame capable of rotating left and right and up and down. [0004] In order to achieve the above object, the present invention provid...
