Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, and particularly relates to a special hoisting device for replacing the lining plate of a ball mill. Background Technique

[0002] Ball mills are widely used in many industrial fields, such as mining, building materials, chemical industry, etc. The lining plate is one of the key components of the ball mill, which directly bears the impact, wear and corrosion of the grinding media and materials in the ball mill. With the long-term operation of the ball mill, the lining plate will gradually wear and needs to be replaced regularly to ensure the normal working efficiency and service life of the ball mill. However, the replacement of the ball mill lining plate is a complex and challenging task. Since the lining plate is usually large in volume and heavy in weight, and the internal space of the ball mill is relatively narrow with a complex operating environment, it brings great difficulties to the replacement of the lining plate.

[0003] In the traditional hoisting operation for replacing the lining plate, some use a single hook for hoisting. However, during the hoisting process with a single hook, the lining plate is prone to unstable phenomena such as tilting and shaking because it is difficult to accurately grasp the center of gravity of the lining plate, and the single-point hoisting method of the single hook is difficult to keep the lining plate balanced. This not only increases the operation difficulty but also may cause the lining plate to collide with the inner wall of the ball mill, resulting in equipment damage. Content of the Utility Model

Then, the lining plate is hoisted to the corresponding position of the lining plate installation hole. Then, the lining plate is installed on the lining plate installation hole through the fixing bolts. The double hooks can lift the lining plate from two different points, making the force on the lining plate more balanced during the hoisting process. Compared with a single hook, the lining plate will not tilt or rotate due to single-point force, which helps to maintain the stable posture of the lining plate during the rising and moving process. The double hooks can complete the hoisting preparation work of the lining plate faster. The operator can quickly connect the two hooks to the lining plate without spending too much time adjusting the hook position and balancing the lining plate.

[0035] Working principle: When replacing the lining plate of the ball mill, first find the corresponding position of the lining plate mounting hole on the lining plate mounting block 3111 inside the rotating cylinder of the ball mill. Then, hold the mounting plate 1 and install the entire hoisting device inside the lining plate mounting hole through the threaded connection block 313. Let the personnel outside the rotating cylinder of the ball mill drive the threaded connecting rod 316 to be threadedly connected with the threaded connection block 313 by rotating the handwheel 317. Then, drive the threaded fixing rod 318 to rotate by rotating the rotating block 319, and fix and install the entire hoisting device on the inner wall of the rotating cylinder of the ball mill through the fixing plate 315 and the rubber cushion block 314. Then, pull out the hoisting ropes 419 on the winches 4116 respectively, and then hang the hooks 4112 on different lifting rings of the lining plate respectively. Then, start the first motor 413 and the second motor 4113 respectively. After the first motor 413 and the second motor 4113 are started, they drive the rotating rods 418 to rotate respectively. When the rotating rods 418 rotate, they drive the winches 4116 to rotate. When the winches 4116 rotate, the hoisting ropes 419 are guided by the guide wheels 417 and the guide hoppers 4117 to drag the lining plate to the position below the corresponding position of the lining plate mounting hole, and then lift the lining plate to the corresponding position of the lining plate mounting hole, and then install the lining plate on the lining plate mounting hole through the fixing bolts.
