Technical Field
[0001] The utility model relates to the technical field of cone crushers, and specifically, to a hydraulic adjustment structure of a cone crusher. Background Art
[0002] A cone crusher is a commonly used type of crusher. When working properly, it is necessary to adjust the distance between the crushing wall and the mantle to determine the size of the discharge particle size. As Figure 1 shown, the specific operation is to release the pressure of the locking cylinder 101. The piston rod of the locking cylinder 101 retracts due to the pressure of the disc spring. At this time, the distance between the locking ring 102 and the support sleeve 103 decreases, and the force acting on the thread of the adjusting sleeve 104 disappears, so that the adjusting sleeve 104 is in a free state. At this time, operate the hydraulic motor 105 to rotate, drive the large gear ring 106 and the adjusting sleeve 104 to rotate downward or upward, so that the distance between the mantle 107 and the crushing wall 108 installed on the adjusting sleeve changes. When the visual inspection reaches the required discharge port, stop the operation of the hydraulic motor 105, and apply pressure to the locking cylinder 100 to make the piston rod extend to tightly press the support sleeve 103. At this time, the spiral groove inside the locking ring 102 is upward, the spiral groove inside the support sleeve 103 is downward, and is tightened and positioned with the spiral groove outside the adjusting sleeve 103, so as to achieve the operation of adjusting the discharge port.
[0003] The spiral groove inside the locking ring 102, the spiral groove inside the support sleeve 103, and the spiral groove outside the adjusting sleeve 104 need to be closely fitted during work to achieve normal operation. However, during work, the spiral grooves of the locking ring 102, the support sleeve 103, and the adjusting sleeve 104 often have poor contact, resulting in serious local wear. Only by reworking or replacing the entire component can it work normally, resulting in time-consuming and laborious work.
[0004] In addition, the 12 locking cylinders evenly distributed around the circumference of the locking ring 102 are used in series through pipelines. During work, the locking ring is unevenly stressed and skewed, so the contact with the spiral groove outside the adjusting sleeve 104 is not good. In extreme cases, due to single-point stress, the adjusting sleeve rotates by itself during heavy work and sintering occurs, affecting the subsequent work.
[0005] When adjusting the discharge port, since the locking ring is in a loosened state, when the hydraulic motor 105 rotates to drive the adjusting sleeve 104 to rotate, the adjusting sleeve rotates inside the locking ring and the support sleeve. Due to the too large gap, it gets stuck, and the worker needs to tap it to reset before continuing to rotate the adjusting sleeve for adjustment, which is troublesome and time-consuming.
[0006] In short, the above problems are all related to the precise fit required by the spiral groove. A new solution needs to be proposed for this problem. Content of the Utility Model

[0033] The technical solution of the present utility model will be further described in detail below through specific implementation modes.
[0034] As Figures 2 - 4 shown, a hydraulic adjustment structure of a cone crusher includes a crushing wall 107, an adjusting sleeve 104, an adjusting ring 110, a support ring 111, a locking ring 102, a support sleeve 103, a tensioning hydraulic cylinder 112 and an adjusting hydraulic cylinder 113.
[0035] The inner wall of the lower end of the adjusting sleeve 104 and the outer wall of the crushing wall 107 are the spacing to be adjusted.
[0036] An adjusting hydraulic cylinder 113 is arranged between the outer edge of the adjusting sleeve 104 and the outer edge of the support sleeve 103 for adjusting the size of the spacing to be adjusted, and the support sleeve is a structure with a fixed position relative to the adjusting sleeve.
[0037] Specifically, a first support platform 114 is arranged at the upper end of the support sleeve 103, the bottom of the adjusting hydraulic cylinder 113 is installed on the first support platform 114, and the piston rod of the adjusting hydraulic cylinder 113 is fixedly connected with the adjusting sleeve 104 by threads to ensure the straightness of the lifting action. Among them, the adjusting hydraulic cylinder 113 is set as a hydraulic cylinder with scales to improve the adjustment accuracy.
[0038] The locking ring 102 is installed on the support sleeve 103 through a tensioning hydraulic cylinder 112. Specifically, in this embodiment, a second support platform 115 is arranged at the upper end of the support sleeve 103, the first support platform 114 is located outside the second support platform 115, the piston rod of the tensioning hydraulic cylinder 112 is hinged to the second support platform 115, and the cylinder body of the tensioning hydraulic cylinder 112 is fixed to the locking ring 102. A plurality of guide holes are arranged on the circumference of the locking ring 102, and a guide rod 116 is installed in each guide hole, and the lower end of the guide rod 116 is fixed to the support sleeve 103.
[0039] The height of the first support platform 114 is greater than the height of the second support platform 115, and the specification of the adjusting hydraulic cylinder 113 is higher than that of the tensioning hydraulic cylinder 112.
[0040] Two adjusting rings and a support ring 117 are arranged between the locking ring 102 and the support sleeve 103. The support ring and the adjusting rings are made of steel. The adjusting rings are tapered circular rings with a thin outer circumference and a thick inner circumference, and the support ring 117 is a tapered circular ring with a thin inner circumference and a thick outer circumference. The inner wall of the first adjusting ring 118 is in close contact with the outer wall of the adjusting sleeve 104, its upper edge abuts against the lower end of the locking ring 102, and its lower edge abuts against the upper edge of the support ring 117.

[0043] Technical principle description:
[0044] During adjustment, first loosen the tensioning hydraulic cylinder 112. The locking ring 102 moves upward, and the pressure on the first adjusting ring 118 and the second adjusting ring 119 disappears. Due to their own elastic deformation, they expand outward, causing the circumferential locking force of the adjusting sleeve 104 to disappear and allowing it to move freely up and down.
[0045] The gap between the adjusting ring and the adjusting sleeve 104 depends on the specific parameters of each device to ensure the coaxiality and non-deviation requirements when the adjusting sleeve 104 moves up and down.
[0046] Then, operate the adjusting hydraulic cylinder 113 to move up and down as needed, and adjust according to the reading on the piston rod of the adjusting hydraulic cylinder 113. After reaching the required data, stop the operation of the adjusting hydraulic cylinder. At this time, operate the tensioning hydraulic cylinder 112 to apply a downward force on the locking ring 102, drive the adjusting ring to shrink, and clamp the adjusting sleeve 104. After reaching the specified pressure of the tensioning hydraulic cylinder, maintain the pressure according to the specified pressure. At this time, release the pressure of the adjusting hydraulic cylinder to make the piston rod in a free state to avoid the impact on the adjusting hydraulic cylinder due to overload during operation.
[0047] Finally, it should be noted that: The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
