Description

Technical Field

[0001] The present application relates to the technical field of ball mill maintenance tools, and in particular to a ball mill liner installation and hoisting device. Background Art

[0002] Ball mills are mainly used in the field of ore metallurgy. Their main function is to crush and grind coarse ore. Their working principle is: add ore and small steel balls into the ball mill in a certain proportion, and drive the ball mill to rotate through the motor, so that the small steel balls inside are constantly thrown up and down, thereby crushing and grinding the ore. In order to prevent the small steel balls from wearing the inner wall of the ball mill cylinder, a liner is laid on the inner wall of the ball mill cylinder, and each liner weighs about 150kg.

[0003] When the ball mill is overhauled, the worn liner needs to be replaced. Currently, the liner is replaced mainly by manual replacement, which requires four workers to enter the ball mill cylinder, remove the worn liner together, and replace it with a new one. This method is not only inefficient, but also labor-intensive, and due to the heavy weight of the liner, safety accidents are prone to occur during the handling process, which poses a great safety hazard.

[0024] See also Figure 1The ball mill liner installation and hoisting device includes an anchor ring 4, a connecting hook 5, a steel rope 7, a slider 8, and a hand chain hoist 9. The ball mill 1 is used to crush and grind coarse ore. A feed end cover 2 and a discharge end cover 3 are respectively provided at both ends of the ball mill 1 to close the ball mill 1. A feed port is provided at the center of the feed end cover 2, and a discharge port is provided at the center of the discharge end cover 3. There are six anchor rings 4, which are divided into two groups, one of which is fixedly connected to the middle position of the feed end cover 2 and evenly distributed on the side of the feed port, and the other group is fixedly connected to the middle position of the discharge end cover 3 and evenly distributed on the side of the discharge port, and the two groups of anchor rings 4 are symmetrical to each other. The reason for this is that if only one pair of anchor rings 4 is provided in the ball mill 1, it is difficult to accurately control the position where the anchor ring 4 stays when the ball mill 1 stops rotating, so that the position where the anchor ring 4 stays does not correspond to the position where the liner 10 needs to be replaced, resulting in a large deviation between the position after the steel rope 7 is erected and the position where the liner 10 needs to be replaced, thereby affecting the replacement of the liner 10. In the present application, by providing three pairs of anchor rings 4 in the ball mill 1, workers can freely select the erection position of the steel rope 7 according to actual conditions, thereby ensuring the smooth progress of the replacement process of the liner 10.

[0025] See also Figure 2 , both ends of the steel rope 7 are fixedly connected with connecting hooks 5. When in use, the connecting hooks 5 are respectively hung on the anchor rings 4 on both sides, thereby completing the installation of the steel rope 7. Further, in order to facilitate the subsequent lifting of the lining plate 10, the steel rope 7 needs to be tightened. Therefore, a basket bolt 6 is also installed at the connection between the connecting hook 5 and the steel rope 7 at one end. One end of the basket bolt 6 is fixedly connected to the connecting hook 5, and the other end is fixedly connected to the steel rope 7. When in use, after the connecting hooks 5 at both ends are hung on the anchor ring 4, the steel rope 7 can be tightened by rotating the basket bolt 6, thereby facilitating the subsequent lifting of the lining plate 10.

[0026] See also Figure 3 The connecting hook 5 includes a hook 51, a stopper 52, and a positioning pin 54. A hinge column 53 is provided on the hook 51. One end of the stopper 52 is hingedly connected to the hinge column 53, so that the stopper 52 can rotate around the hinge column 53. The other end of the stopper 52 is fixedly connected to the end of the hook 51 through the positioning pin 54, thereby closing the opening of the hook 51 to prevent the hook 51 from falling off the anchor ring 4 when in use, thereby improving the stability of the steel rope 7 after erection. When the connecting hook 5 needs to be removed, the positioning pin 54 is pulled out, the stopper 52 is opened, and the hook 51 can be removed.

[0027] See also Figure 2 , 4A slider 8 is slidably connected to the steel rope 7. A through hole is provided on the slider 8. Pulleys 81 are rotatably installed on the upper and lower sides of the through hole. The steel rope 7 passes between the pulleys 81 on the upper and lower sides. The pulleys 81 can reduce the friction between the slider 8 and the steel rope 7, thereby facilitating the lifting of the lining 10. A hand chain hoist 9 is fixedly installed at the bottom of the slider 8. The lining 10 is lifted or lowered by the hand chain hoist 9, and the lining 10 is transferred by the slider 8, thereby completing the replacement of the lining 10.

[0028] Two positioning holes are usually provided on the liner 10, and a protrusion for positioning the liner 10 is provided on the inner wall of the cylinder of the ball mill 1. When lifting the liner 10, first pass the lifting rope 11 through the positioning hole on the liner 10, and then connect the two ends of the lifting rope 11 together to complete the fixation of the liner 10. Finally, use the hand winch 9 to lift the lifting rope 11 to transport the liner 10.

[0029] Specific working process:

[0030] The worker enters the ball mill 1, hangs the connecting hooks 5 at both ends on the corresponding anchor rings 4, completes the installation of the steel rope 7, removes the liner 10 to be replaced, fixes the liner 10 with the lifting rope 11, lifts the liner 10 with the hand winch 9, transfers the worn liner 10 with the slider 8, and then lifts the new liner 10 to the replacement location for installation, thus completing the replacement of the liner 10.
