Example one

As shown in fig. 1, the pulley assembly according to the embodiment of the present application includes a circular positioning ring 1, a fixed pulley 2 and a positioning bolt 3, which are formed by splicing, wherein the positioning ring 1 coaxially abuts against the inner wall of the cylinder, the fixed pulley 2 is rotatably connected to the top of the positioning ring 1, the positioning bolt 3 is screwed on the positioning ring 1, and the outer end of the positioning bolt 3 is inserted into a bolt hole on the cylinder. When the mounting position of the fixed pulley 2 is adjusted, the positioning bolt 3 is firstly screwed to be separated from a bolt hole on a machine barrel, then the positioning ring 1 is pulled to integrally move to a target position, then the positioning bolt 3 is screwed into the bolt hole, the positioning ring 1 supports and fixes the fixed pulley 2, the positioning bolt 3 plays a role in positioning the positioning ring 1, the adjustment of the position of the fixed pulley 2 can be quickly completed in the machine barrel, and the problem brought forward in the background technology is solved.

As shown in fig. 2 and 3, the positioning ring 1 is formed by splicing a first spliced portion 10 and a second spliced portion 20, the radians of the first spliced portion 10 and the second spliced portion 20 are the same and are 180 degrees, a support rod 11 is arranged at the middle position of the first spliced portion 10, the support rod 11 is located at the inner side of the positioning ring 1, the fixed pulley 2 is rotatably arranged on the support rod 11, and the top of the fixed pulley 2 is close to the periphery of the positioning ring 1.

Cardboard 12 is constructed at the both ends of first concatenation portion 10, and the both ends of second concatenation portion 20 are constructed and are had draw-in groove 21, and the joint of cardboard 12 adaptation is in draw-in groove 21 to make first concatenation portion 10 and second concatenation portion 20 enclose and close and form the confined ring.

Positioning bolt 3 arranges the junction at first concatenation portion 10 and second concatenation portion 20, positioning bolt 3 passes the both sides wall of cardboard 12 and draw-in groove 21 simultaneously to keep threaded connection with the both sides wall of cardboard 12 and draw-in groove 21, utilize positioning bolt 3 to make first concatenation portion 10 and second concatenation portion 20 fixed connection together, positioning bolt 3's outer end stretches out to the outside of holding ring 1, and insert the bolt hole that corresponds on the barrel, thereby realize the inside location of holding ring 1 in the barrel.

As an example, the positioning bolts 3 are arranged along the radial direction of the positioning ring 1, and two positioning bolts 3 are symmetrically arranged on the positioning ring 1.

It should be noted that the positioning ring 1 has a certain axial length, the positioning ring 1 is coaxially attached to the inner wall of the cylinder, and the positioning ring 1 can be ensured to be coaxial with the cylinder by utilizing the certain axial length of the positioning ring 1, so that the positioning ring 1 is prevented from deflecting, and the positioning ring 1 is limited to move only along the axial direction of the cylinder.

It should be noted that, by setting the position of the fixed pulley 2 close to the outer periphery of the positioning ring 1, the distance between the fixed pulley 2 and the inner wall of the cylinder can be reduced as much as possible, and the steel lining plate can be lifted to a greater height.
