Detailed Description
The utility model will be described in detail with reference to the accompanying drawings and detailed description.
Example 1
The utility model provides an axial displacement protection device, which is shown in fig. 1, and comprises a base cylinder 1, wherein a plurality of adjusting screw holes are uniformly arranged on the side wall of the base cylinder 1 at intervals along the circumferential direction, an adjusting bolt 2 is connected in the adjusting screw holes along the radial direction of the base cylinder 1, and the tail part of the adjusting bolt 2 is movably connected with a bearing bush 3 which is positioned in the base cylinder 1 and has the same direction as the inner wall of the base cylinder 1, as shown in fig. 2.
Example 2
The other structures are the same as those of the embodiment 1, except that, as shown in fig. 3, the outer wall of the bearing bush 3 is fixedly connected with a limiting cavity 4, a limiting opening 5 is formed in the limiting cavity 4, the tail of the adjusting bolt 2 extends into the limiting cavity 4 through the limiting opening 5 and is fixedly provided with a limiting block 6 with a size larger than that of the limiting opening 5, one end of the limiting block 6, far away from the adjusting bolt 2, is in a plane shape, and the top end of the outer wall of the bearing bush 3 is fixedly provided with a boss 7 which is adaptive to the plane end shape of the limiting block 6.
Example 3
The rest of the structure is the same as that of the embodiment 1, except that when the belt backstop 10 is fixed, a fixing ring 8 is coaxially connected to the outside of one end of the base cylinder 1, and a plurality of fixing holes 9 are uniformly arranged on the fixing ring 8 at intervals along the circumferential direction.
Example 4
The rest of the structure is the same as that of example 1, except that in order to prevent the inner wall of the bush 3 from directly scratching the outer wall of the drum shaft, the inner wall of the bush 3 is covered with a rubber pad.
When in use, as shown in fig. 4, taking the belt backstop 10 adopted by a belt team at present as an example, the fixing ring 8 is aligned with the rotating part 11, the fixing hole 9 corresponds to a screw hole on the rotating part 11, the fixing ring 8 is fixed on the rotating part 11 through the fixing bolt, and then the base cylinder 1 and the rotating part 11 are coaxially fixed; for other types of belt backstop, for example, the rotating part is not provided with a screw hole, and the fixed ring 8 can be directly welded on the rotating part, so that the purpose of coaxially fixing the base cylinder 1 and the rotating part 11 can be achieved. And then the rotating part 11 is sleeved with a roller shaft, one end of the roller shaft, far away from the roller, penetrates through the rotating part 11 and then stretches into the base cylinder 1, at the moment, the adjusting bolt 2 is screwed into the inner direction of the base cylinder 1, the tail part of the adjusting bolt 2 is movably connected in the limiting cavity 4, and is propped against the outer wall of the bearing bush 3 during screwing, only radial force is transmitted to the outer wall of the bearing bush 3, so that the bearing bush 3 is tightly pressed on the roller shaft inwards, and a rubber pad on the inner wall of the bearing bush 3 can prevent the bearing pad from directly scratching the outer wall of the roller shaft.
