Description

Technical Field

[0001] This invention relates to lifting tools, specifically to a practical lifting tool for replacing the liner plates of a large ball mill cylinder. Background Technology

[0002] Mining and beneficiation plants with a daily ore processing capacity of over 10,000 tons typically use large ball mills, exceeding 6 meters in diameter and 10 meters in length. These mills contain numerous internal cylinder liners, numbering over four to five hundred, each weighing over 250 kg. When the liner wear cycle is reached, replacement becomes difficult due to the long axial dimension and short radial dimension of the cylinder, coupled with limitations imposed by auxiliary feeding and discharging facilities (feed trolleys, feed seals, discharge cylindrical screens, etc.). Dedicated liner replacement robots cannot be used on-site, and there are no suitable lifting tools for disassembling, installing, and transporting new and old cylinder liners. This results in lengthy replacement times, high safety risks, and low efficiency, significantly impacting the beneficiation plant's start-up time and production targets. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a practical hoisting tool for replacing the liner plates of a large ball mill cylinder.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A practical lifting tool for replacing the liner plates of a large ball mill cylinder includes a cylinder, an old liner plate and a new liner plate disposed on the inner wall of the cylinder, and further includes:

[0006] A conveying mechanism, which is installed on the cylinder, is used to transport the old liner to the outside of the cylinder and to transport the new liner to the inside of the cylinder.

[0007] A cooperating mechanism is provided between the old liner and the new liner, and is used to cooperate with the conveying mechanism to convey the new liner to the inner wall of the cylinder;

[0008] An auxiliary mechanism, located on the cooperating mechanism, is used to assist the conveying mechanism in adjusting the installation position of the new liner on the cylinder.

[0009] Preferably, the conveying mechanism includes:

[0013] Preferably, the height of the second support frame is higher than the height of the first support frame, and the support member further includes an auxiliary frame disposed on the slide rod for auxiliary support.

[0014] Preferably, the pulley block includes two sets of pulleys and a base located at the bottom of the slide bar, and the second winch is fixedly installed at the lower end of the base by a mounting component.

[0015] Preferably, the coupling mechanism includes a lifting ring on the cylinder, a handle on the new liner, and a wire rope threaded through the lifting ring.

[0016] Preferably, one end of the wire rope is mounted on the second winch, and the other end is connected to the handle for pulling the new liner away from the second winch.

[0017] Preferably, the auxiliary mechanism includes:

[0018] An auxiliary plate is used to adjust the installation position of the new liner on the cylinder by contacting and moving the handle.

[0019] The rotating component includes a rotating rod disposed on the auxiliary plate, a fixed plate disposed on both sides of the rotating rod and rotatably connected to the rotating rod, and a motor for driving the rotating rod to rotate;

[0020] The second displacement component includes a second sliding plate disposed on one side of the fixed plate and a second sleeve plate sleeved on the second sliding plate, for moving the horizontal position of the auxiliary plate;

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-6 A practical lifting tool for replacing the liner plates of a large ball mill cylinder includes a cylinder 1, an old liner plate 3 and a new liner plate 4 disposed on the inner wall of the cylinder 1, and further includes:

[0037] The conveying mechanism 2 is installed on the cylinder 1 and is used to transport the old liner 3 to the outside of the cylinder 1 and to transport the new liner 4 to the inside of the cylinder 1.

[0038] The cooperating mechanism is located between the old liner 3 and the new liner 4, and is used to cooperate with the conveying mechanism 2 to convey the new liner 4 to the inner wall of the cylinder 1;

[0039] Auxiliary mechanism 8, located on the cooperating mechanism, is used to assist the conveying mechanism 2 in adjusting the installation position of the new liner 4 on the cylinder 1.

[0040] In this design, both the old liner 3 and the new liner 4 are bolted to the inner wall of the cylinder 1. The conveying mechanism 2 removes the old liner 3 from the cylinder 1 and moves the new liner 4 into the cylinder 1. A cooperating mechanism then pulls the new liner 4, which has been moved into the cylinder 1, onto the inner wall of the cylinder 1. Next, the auxiliary mechanism 8 adjusts the installation position of the new liner 4 on the inner wall of the cylinder 1, facilitating installation by workers. This tool speeds up the conveying speed of the old liner 3 and the new liner 4, and also accelerates the installation speed of the new liner 4, improving the overall efficiency of replacing the ball mill liner 4.

[0041] In one embodiment, the conveying mechanism 2 includes:

[0042] The support includes a second support frame 202 with one end located on the outside of the cylinder 1 and a first support frame 201 located inside the cylinder 1;

[0043] The sliding component includes a slide rod 203 disposed between the first support frame 201 and the second support frame 202, a slide groove 204 disposed on both sides of the slide rod 203, and a pulley assembly disposed on the slide groove 204;

[0044] The power components include a second winch 211 located at the bottom of the pulley block and a first winch 206 located on the second support frame 202.

[0045] In one embodiment, the height of the second support frame 202 is higher than the height of the first support frame 201, and the support member also includes an auxiliary frame 205 disposed on the slide bar 203 for auxiliary support.

[0046] In one embodiment, the pulley block includes two sets of pulleys 207 and a base 208 located at the bottom of the slide bar 203. The second winch 211 is fixedly installed at the lower end of the base 208 by a mounting component.

[0047] In this design, the slide bar 203 is detachably mounted to the first support frame 201 and the second support frame 202 by bolts. The pulley 207 is rotatably connected to the base 208, and the base 208 and the slide bar 203 are slidably connected. The pulley 207 slides along the slide groove 204, and the base 208 prevents the pulley 207 from falling out of the slide groove 204. The mounting components include a support plate 209 fixedly connected to the lower end of the base 208 and a support plate 210 fixedly connected to the lower end of the support plate 209. The second winch 211 is bolted to the support plate 210. The first winch 206 is fixedly mounted to the second support frame 202. The first winch 206 moves the position of the second winch 211 on the slide bar 203. The second winch 211 hooks up and drags the old liner 3 on the inner wall of the cylinder 1 until it reaches the lower end of the old liner 3. The first winch 206 pulls the second winch 211 to slide along the slide groove 204 to the outside of the cylinder 1. Then the second winch 211 lifts the new liner 4 from the outside of the cylinder 1. Since the height of the second support frame 202 is higher than the height of the first support frame 201, the second winch 211 drives the new liner 4 to slide along the slide groove 204 into the cylinder 1 under the action of gravity.

[0048] In one embodiment, the cooperating mechanism includes a lifting ring 6 on the cylinder 1, a handle 7 on the new liner 4, and a wire rope 9 threaded through the lifting ring 6.

[0049] In one embodiment, one end of the wire rope 9 is attached to the second winch 211, and the other end is connected to the handle 7 for pulling the new liner 4 away from the second winch 211.

[0050] In this design, the cylinder 1 has an installation channel 5, which is a reserved space between the new liner plate 4 and the old liner plate 3. Before each new liner plate 4 is moved to the inner wall of the cylinder 1, a lifting ring 6 is installed above the location where the new liner plate 4 is to be installed. The lifting ring 6 is bolted to the installation channel 5, and the handle 7 is bolted to the new liner plate 4. When preparing to move the new liner plate 4 to the inner wall of the cylinder 1, the wire rope 9 of the second winch 211 is passed through the lifting ring 6. Then, the hook at the end of the wire rope 9 hooks the handle 7 on the new liner plate 4. The wire rope 9 pulls the new liner plate 4 away from the second winch 211 and moves it towards the inner wall of the cylinder 1. When the second winch 211 pulls the new liner plate 4, it generates a horizontal force, which makes the slide bar 203 prone to tipping over. The auxiliary frame 205 plays a role in limiting the tipping of the slide bar 203.

[0051] In one embodiment, the auxiliary mechanism 8 includes:

[0052] The auxiliary plate 809 adjusts the installation position of the new liner 4 on the cylinder 1 by contacting and moving the handle 7;

[0053] The rotating component includes a rotating rod 812 disposed on an auxiliary plate 809, a fixed plate 811 disposed on both sides of the rotating rod 812 and rotatably connected to the rotating rod 812, and a motor 810 for driving the rotating rod 812 to rotate.

[0054] The second shifting component includes a second sliding plate 807 disposed on one side of the fixed plate 811 and a second sleeve plate 806 sleeved on the second sliding plate 807, for moving the horizontal position of the auxiliary plate 809.

[0055] The first shifting component is connected to the lifting ring 6 via an extension plate 61 provided on the lifting ring 6, and is used to adjust the height of the auxiliary plate 809.

[0056] In one embodiment, a telescopic rod 808 for driving the second sliding plate 807 to slide within the second socket plate 806 is hinged to the second sliding plate 807 and the second socket plate 806.

[0057] In one embodiment, the first shifting member includes a first sliding plate 802 disposed at one end of the second socket plate 806 and a first socket plate 801 sleeved on the first sliding plate 802.

[0058] In one embodiment, the first socket plate 801 is provided with a cylinder 804 for driving the first sliding plate 802 to slide within the first socket plate 801. The cylinder 804 is connected to the first socket plate 801 and the first sliding plate 802 through a connector.

[0059] In this design, one end of the extension plate 61 is fixedly connected to the first socket plate 801, and the other end is fixedly connected to the lifting ring 6. The connecting components include a mounting block 803 fixedly connected to the first socket plate 801 for fixing the cylinder 804, and a U-shaped plate 805 located at the output end of the cylinder 804. The U-shaped plate 805 is fixedly connected to the first sliding plate 802. The second socket plate 806 is fixedly connected to the first sliding plate 802. The fixed plate 811 and the second sliding plate 807 are fixedly connected. The motor 810 is fixedly mounted on one of the fixed plates 811. The output shaft of the motor 810 is fixedly connected to the rotating rod 812 via a coupling. The auxiliary plate 809 is fixedly connected to the rotating rod 812. When the wire rope 9 drags the new liner 4 to the inner wall of the cylinder 1, since the wire rope 9 can only drag the new liner 4 to a rough position on the inner wall of the cylinder 1, it is necessary to make a fine adjustment to the installation position of the new liner 4 on the inner wall of the cylinder 1. At this time, the cylinder 804 is activated, and the first sliding plate 802 slides in the first connecting plate 801 to adjust the matching height between the auxiliary plate 809 and the new liner 4; the telescopic rod 808 is activated, and the second sliding plate 807 slides in the second connecting plate 806 to adjust the matching horizontal distance between the auxiliary plate 809 and the new liner 4; the motor 810 is activated, the auxiliary plate 809 rotates, and the auxiliary plate 809 hooks the handle 7, which assists in adjusting the installation position of the new liner 4 under the pull of the wire rope 9. After the new liner 4 is installed, the handle 7 is removed.

[0060] Working principle: During use, the conveying mechanism 2 moves the old liner 3 out of the cylinder 1 and moves the new liner 4 into the cylinder 1. A cooperating mechanism then pulls the new liner 4, already inside the cylinder 1, onto the inner wall of the cylinder 1. Next, the auxiliary mechanism 8 adjusts the installation position of the new liner 4 on the inner wall of the cylinder 1, facilitating installation by the worker. This tool speeds up the conveying speed of the old liner 3 and the new liner 4, and also accelerates the installation speed of the new liner 4, improving the overall efficiency of replacing the ball mill liner 4.
