[0005] Technical solution: The utility model is a two-transport articulated connection device for a tunnel boring machine, which is characterized by: comprising a mounting frame, which is connected to the first conveyor by bolts, and the first conveyor is provided with a plurality of mounting holes for setting the mounting frame; the mounting frame is connected to the left and right swing frames by pin shaft one, the left and right swing frames are connected to the connecting frame by pin shaft two, and the connecting frame is connected to the two transports by pin shaft three.
[0006] Wherein, the two ends of the left and right swing frames are connected to the mounting frame and the connecting frame respectively through pin shaft 1 and pin shaft 2.
[0007] Among them, the two ends of the connecting frame are connected to the left and right swing frames and the second swing frame through pin shaft 2 and pin shaft 3 respectively.
[0008] Wherein, the bolts are matched with washers and nuts.
[0009] The bolts are connected with nuts after passing through the bolt holes and washers corresponding to the mounting frame and the first conveyor.
[0010] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model is easy to install, has a better structure, can adjust the installation position of the second movement, and realize the large-angle swing of the second movement in the horizontal direction. It can effectively avoid the collision between the second movement and the fuselage and the connecting frame, and does not interfere with the adjustment of the second movement tensioning device and the lubrication of the second movement roller. The state of the second movement can be adjusted, the connection method is flexible, and the applicability of the second movement is improved. BRIEF DESCRIPTION OF THE DRAWINGS
