Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an adjustable steering linkage of mining dump truck, includes two body of rod 2, is connected with adjusting device 3 between two body of rod 2, and adjusting device 3 includes connecting block 9 and connecting block 9 both ends welded connecting rod 4, and the one end of two connecting rods 4 all is equipped with rolling disc 5, and two rolling discs 5 rotate respectively to be established in the body of rod 2 of both sides.

Further, open and shut on the outer wall of the body of rod 2 and have through-hole 7, on the one end of through-hole 7 extended to rolling disc 5, the spin closed was equipped with bolt 10 on the rolling disc 5, and on the one end of bolt 10 extended to connecting rod 4, can take off bolt 10 from rolling disc 5 and connecting rod 4 through-hole 7, made things convenient for connecting rod 4 and rolling disc 5 to break away from the connection.

Specifically, the rotating disc 5 is provided with a groove 11, one end of the connecting rod 4 extends into the groove 11, the connecting rod 4 is provided with a threaded hole 12, when one end of the bolt 10 is screwed into the threaded hole 12, the connecting rod 4 is limited to be incapable of rotating in the groove 11, and when the through hole 7 and the threaded hole 12 are located on the same axis, the bolt 10 can be taken out.
