Description

Technical Field

[0001] The invention relates to the field of ball mills, and in particular to a ball mill liner loading and unloading auxiliary device. Background Art

[0002] The ball mill is a key equipment for crushing the ore after it is crushed. The drum of the common ore ball mill is set horizontally, with a diameter of 3-9 meters and a length of 5-13 meters, and it is relatively large. The working principle of the ball mill is to throw and collide the steel balls and ore in the drum through the rotation of the drum, thereby crushing and grinding the ore. During the operation of the ball mill, the thrown steel balls and ore will impact the lining of the inner wall of the drum, severely wearing the lining. The lining is a consumable and needs to be replaced regularly. The traditional way to replace the lining is to use ropes to lift the lining, and multiple workers position and load and unload the lining in the drum by pulling, dragging, pushing, and moving. However, the weight of the lining is 500-2000kg, which is difficult to transport by manpower alone. The working temperature in the drum is above 50°C and the humidity is above 98%, and the working conditions are very harsh. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0022] For the convenience of description below, the side of the liner 8 connected to the side wall of the ball mill drum is called the outer side of the liner 8, and the side of the liner 8 away from the ball mill drum is called the inner side of the liner 8.

[0023] like Figures 1 to 15 As shown, the present invention provides a ball mill liner loading and unloading auxiliary device (hereinafter referred to as the auxiliary device), and each part of the auxiliary device is made of titanium alloy. The auxiliary device includes a walking assembly 1, a primary transport assembly 2 and a secondary transport assembly 3. The walking assembly 1 is used to drive the auxiliary device to move along the axial direction of the ball mill drum (hereinafter referred to as the drum), and the walking assembly 1 includes a connecting block 11, a retractable support leg 12 and a caster assembly 13. Please refer to Figure 4The connection block 11 is rotatably connected to four retractable support legs 12. Specifically, the upper and lower ends of the left and right sides of the connection block 11 are rotatably connected to one end of the retractable support leg 12 through the first hinge 4, and the other end of the retractable support leg 12 is telescopically connected to the caster assembly 13. In the use state, the axis of the connection block 11 is roughly in line with the axis of the drum, and the four retractable support legs 12 extend radially along the drum. By adjusting the length of the retractable support legs 12, the caster assembly 13 can be fitted with the inner wall of the drum, and the walking assembly 1 can be pushed to move along the axis of the drum.

[0024] As an embodiment of a retractable support leg 12, the retractable support leg 12 includes an outer rod 121 and an insertion rod 122. One end of the outer rod 121 is hinged to the connection block 11 through the first hinge 4, and the other end of the outer rod 121 is an open structure. The insertion rod 122 is inserted into the outer rod 121, and the insertion rod 122 can slide in the outer rod 121 along the length direction of the outer rod 121. In order to fix the position of the insertion rod 122 in the outer rod 121, the outer rod 121 is provided with a plurality of first avoidance holes 1211 at equal intervals along its length direction, and the insertion rod 122 is provided with a plurality of second avoidance holes (not shown in the figure) at equal intervals along its length direction. When in use, the first bolt 5 can be used to pass through the first avoidance hole 1211 and the second avoidance hole in sequence to fix the positions of the outer rod 121 and the insertion rod 122.

[0025] Since one end of the retractable support leg 12 is connected to the connecting block 11 in a rotating connection, the other end of the retractable support leg 12 is abutted against the roller through the caster assembly 13. That is, the position of the retractable support leg 12 is not fixed, which causes the retractable support leg 12 to rotate easily during walking. In order to avoid the above phenomenon, a first mounting groove 1212 is provided in the middle of the outer rod 121, and a corresponding avoidance groove 1221 is provided in the plug rod 122. One end of the reinforcement rod 15 is rotatably arranged in the first mounting groove 1212 through a pin shaft, and the other end of the reinforcement rod 15 is connected to another adjacent outer rod 121 through a pin shaft. At this time, the reinforcement rod 15 and the two adjacent outer rods 121 roughly form a triangular structure to improve the connection stability. In this embodiment, the two outer rods 121 adjacent to each other at the bottom are not connected by the reinforcement rod 15, thereby reserving space for the movement of the lining plate 8.

[0026] As an embodiment of a caster assembly 13, Figure 14-15As shown, the caster assembly 13 includes a mounting frame 131 with hollow structures at both ends, a spring positioning rod 132, a compression spring 133 and a caster body 134. The bottom of the plug rod 122 is inserted into the upper cavity of the mounting frame 131, and this part of the plug rod 122 is provided with a third avoidance hole 1222, and the mounting frame 131 is provided with a flat key groove 1311 corresponding to the third avoidance hole 1222. When in use, the plug pin 135 is inserted into the third avoidance hole 1222 and the flat key groove 1311, and the mounting frame 131 and the plug rod 122 can be assembled. The spring positioning rod 132 is arranged vertically, and the two ends of the spring positioning rod 132 pass through the insertion rod 122 and the mounting frame 131 respectively, and the two ends of the spring positioning rod 132 are respectively against the insertion rod 122 and the mounting frame 131. A compression spring 133 is sleeved on the rod body of the spring positioning rod 132, and the two ends of the compression spring 133 are respectively against the insertion rod 122 and the mounting frame 131. The caster body 134 is rotatably connected in the cavity at the lower end of the mounting frame 131. It can be understood that through the cooperation of the latch 135 with the third avoidance hole 1222 and the flat key groove 1311 and the cooperation of the spring positioning rod 132 with the insertion rod 122 and the mounting frame 131, it can be realized that the mounting frame 131 can move along the length direction of the insertion rod 122, and the mounting frame 131 will not fall off the insertion rod 122.

[0027] The use method of the walking assembly 1 is to first transport the walking assembly 1 to a proper position in the drum, then lift the connecting block 11 to the vicinity of the drum axis, adjust the position and length of the telescopic support legs 12, make the angles between the telescopic support legs 12 roughly the same, and make the caster assembly 13 abut against the inner wall of the drum, and finally connect two adjacent telescopic support legs 12 with the reinforcing rod 15 to complete the installation. Push the walking assembly 1, and the walking assembly 1 can move along the axial direction of the drum.

[0028] The primary transport component 2 is used to transport the liner 8 from the drum mouth to the inside of the drum. Figure 3 , Figure 6 and Figure 7 The primary transport assembly 2 includes a connecting beam 21, a first motor 22 slidably connected to the connecting beam 21, and a transport plate 23. The connecting beam 21 extends along the axis of the drum, and is used to connect the two traveling assemblies 1 into one. The connecting beam 21 also provides a sliding track for the first motor 22, so that the first motor 22 can slide along the length direction of the connecting beam 21.

[0029] Specifically, the connecting beam 21 is a double-layer I-beam structure. For the convenience of description, the upper layer is named as the upper I-beam 211, and the lower layer is named as the lower I-beam 212. Figure 4As shown, the middle of the connection block 11 is provided with a socket 111 corresponding to the shape of the upper I-beam 211. When in use, the upper I-beam 211 is first inserted into the socket 111, and then the upper I-beam 211 is fixed to the connection block 11 with bolts. Both ends of the connection beam 21 are connected to different walking components 1 in the above manner. The lower I-beam 212 provides a sliding track for the first motor 22, please refer to Figure 6 The first motor 22 is fixed in the motor casing 24. The top of the motor casing 24 is provided with a first channel 241 for accommodating the lower I-beam 212. Two rows of first pulleys 242 are provided below the top of the motor casing 24. The two rows of first pulleys 242 are respectively located on both sides of the first channel 241. When in use, the lower I-beam 212 is inserted into the first channel 241, the first pulley 242 contacts the lower I-beam 212, the first pulley 242 provides support for the motor casing 24, and the first pulley 242 rotates to drive the motor casing 24 and the first motor 22 to move.

[0030] The first motor 22 is a dual-output shaft motor, and each output shaft of the first motor 22 is fixedly connected to a winch. In other words, the first motor 22 can control the retraction and extension of the winch cable, and the winch can move with the first motor 22 .

[0031] The transport plate 23 is used to fix the liner 8, please refer to Figure 1 and Figure 7 The transport plate 23 is a semi-frame structure. Figure 7 For example, the left end of the transport plate 23 is an open structure for accommodating the liner 8. Two spaced-apart lifting rings 231 are fixed on the top of the transport plate 23 for connecting the above-mentioned cables. The right side plate of the transport plate 23 is provided with a first through hole 232. When in use, the liner 8 is first placed on the ground in a suitable posture, that is, the outside of the liner 8 faces upward, and then the transport plate 23 is lifted and buckled on the liner 8, so that the through hole of the transport plate 23 and the screw hole on the liner 8 (for fixing the liner 8 on the drum) correspond in position, and then the transport plate 23 and the liner 8 are fixed as a whole with bolts.

[0032] The primary transport assembly 2 is used in the following manner: first, the first motor 22 is moved to the drum mouth, and then the transport plate 23 and the lining plate 8 are fixed together, and then the transport plate 23 is lifted to the vicinity of the first motor 22 by using a crane, and then the cable is fixed to the lifting ring 231, and the first motor 22 is started to tighten the cable, so that the first motor 22 lifts the lining plate 8, and then the motor casing 24 is pushed, so that the lining plate 8 moves along the drum axis together with the motor casing 24 and the first motor 22. Finally, the lining plate 8 is transported from the outside of the drum to the inside of the drum.

[0033] The secondary transport component 3 is used to transport the liner 8 for the second time. In other words, after the primary transport component 2 transports the liner 8 along the axial direction of the drum into the drum, the secondary transport component 3 can drive the liner 8 to move along the radial direction of the drum. Figure 7-Figure 10 The secondary transport assembly 3 includes a movable frame 31 and a transport vehicle 32 disposed in the movable frame 31. The movable frame 31 is suspended on the lower I-beam 212, and the movable frame 31 and the lower I-beam 212 are slidably connected. Specifically, the movable frame 31 is a hollow structure, which includes an upper plate 311, a column 312 and a bottom plate 313, and the upper plate 311 and the bottom plate 313 are connected as a whole through the column 312. Please refer to Figure 7 and Figure 8 A second channel 3111 is provided in the middle of the upper plate 311, a connecting boss 3112 is fixed above the second channel 3111, a second mounting groove 31121 is provided on the lower side of the middle of the connecting boss 3112, a third channel 31122 is provided on the upper side of the middle of the connecting boss 3112, and the third channel 31122, the second mounting groove 31121 and the second channel 3111 are located in correspondence with each other. Two rows of second pulleys 3113 are provided in the second mounting groove 31121, and the two rows of second pulleys 3113 are symmetrically arranged on both sides of the third channel 31122. The movable frame 31 and the lower I-beam 212 are connected in such a manner that the lower I-beam 212 is inserted into the third channel 31122, the second mounting groove 31121 and the second channel 3111, and the second pulley 3113 contacts the upper surface of the lower horizontal plate of the lower I-beam 212.

[0034] In order to improve the firmness of the upper plate 311 , two ends of the upper plate 311 are fixedly connected to two ends of the reinforcing frame 314 , respectively, and a space for accommodating other parts is reserved between the reinforcing frame 314 and the upper plate 311 .

[0035] When in use, the movable frame 31 is pushed, and the movable frame 31 can slide along the connecting beam 21 .

[0036] The transport vehicle 32 includes directional casters 321, a lower chassis 322, an upper chassis 323 and a propulsion structure 324. Each of the four corners below the lower chassis 322 is fixedly connected with a directional caster 321. The directional casters 321 enable the transport vehicle 32 to move only forward or backward. The upper chassis 323 is rotatably connected to the upper part of the lower chassis 322. As an embodiment, the middle part of the upper part of the lower chassis 322 is fixedly connected to the inner ring of the plane bearing (not shown in the figure), and the middle part of the lower part of the upper chassis 323 is fixedly connected to the outer ring of the plane bearing. Please refer to Fig. 9 The lower chassis 322, the upper chassis 323 and the bottom plate 313 are all provided with corresponding limiting holes 6. When in use, the positioning pin 7 is inserted into the limiting hole 6. The positioning pin 7 can limit the rotation of the upper chassis 323 and can also fix the transport vehicle 32 on the movable frame 31.

[0037] A pushing structure 324 is fixed above the upper chassis 323, and the pushing structure 324 can push the lining plate 8 from the middle of the drum to the left or right side of the drum. Figure 2 For example, as an implementation of the pushing structure 324, a push rod motor 3241 and an electromagnet 3242 are arranged from left to right on the upper chassis 323. The push rod motor 3241 is fixedly arranged at the left end of the upper chassis 323 (i.e., the side of the rear of the vehicle). The general working principle of the push rod motor 3241 is that when the motor is started, the push rod moves left and right. The bottom of the electromagnet 3242 is slidably connected to the top of the upper chassis 323, and the left end of the electromagnet 3242 is fixedly connected to the push rod of the push rod motor 3241. The push rod motor 3241 can push the electromagnet 3242 to slide on the upper chassis 323. As another connection method between the electromagnet 3242 and the push rod motor 3241, in order to achieve uniform output of the thrust of the push rod motor 3241, a first iron plate 3243 is fixedly provided at the right end of the push rod of the push rod motor 3241, and the right end of the first iron plate 3243 is fixedly connected to the electromagnet 3242. The provision of the first iron plate 3243 increases the force-bearing area of ​​the electromagnet 3242.

[0038] When in use, the liner 8 is transported to the vicinity of the electromagnet 3242 by using the primary transport assembly 2, the liner 8 is adjusted so that the inner side of the liner 8 is close to the electromagnet 3242, the electromagnet 3242 is started, the liner 8 is adsorbed on the electromagnet 3242, and then the bolts connecting the liner 8 and the transport plate 23 are loosened to remove the transport plate 23. Figure 7 For reference, the push rod motor 3241 pushes the lining plate 8 toward the side wall on the right side of the drum until the lining plate 8 and the drum abut against each other, and then the lining plate 8 is fixed to the drum with bolts to complete the installation.

[0039] The electromagnet 3242 can be a pull-rod switch electromagnet, that is, controlling the pull-rod can control the switch and magnetic force of the electromagnet 3242. Since the inner side of the lining plate 8 is an arc surface, and the electromagnet 3242 is generally a straight surface, it is difficult for the electromagnet 3242 to firmly magnetically attract the lining plate 8. Therefore, please refer to Figure 2 and Fig. 9 An iron block 3244 is also connected to the right side of the electromagnet 3242. The end of the iron block 3244 away from the electromagnet 3242 is an arc surface corresponding to the inner arc surface of the lining plate 8, thereby ensuring the linear transmission of the magnetic force and improving the magnetic force of the electromagnet 3242 on the lining plate 8.

[0040] Since the diameter of some models of rollers is relatively large, it is difficult for the push rod motor 3241 to push the lining plate 8 to the side wall of the roller. Therefore, the secondary transport assembly 3 may further include a transport track 33. The transport track 32 extends substantially in a horizontal direction, and the transport vehicle 32 can move along the transport track 33. Figure 2For example, the transport vehicle 32 can move leftward or rightward along the transport track 33 to approach the side wall on the left or right side of the drum.

[0041] As an implementation of the transport track 33, please refer to Fig.11 and Fig.12 The transport track 33 includes a main track 331, a movable track 332, an extension track 333 and a stable structure 334. The two main tracks 331 are symmetrically arranged. When the transport vehicle 32 is fixed on the movable frame 31, the two sets of directional casters 321 of the transport vehicle 32 correspond to the positions of the main tracks 331, that is, the directional casters 321 can just walk into the main track 331 when walking in a straight line, and then continue to walk in the main track 331. The two main tracks 331 are connected by a connecting rod 335. One end of the main track 331 has a downward step-shaped receiving plate 3311, and the receiving plate 3311 abuts against the bottom plate 313. The two can be connected as one by bolts, and the other end of the main track 331 is rotatably connected to one end of the movable track 332. One end of the main track 331 and the movable track 332 are rotatably connected, and a ramp structure 33111 is provided to ensure the stability of the transport vehicle 32 when it transitions from the main track 331 to the movable track 332. The other end of the movable track 332 is telescopically connected to the extension track 333, that is, the extension track 333 can further extend the length of the movable track 332. As a connection method between the movable track 332 and the extension track 333, the movable track 332 is inserted inside the extension track 333. After adjusting the position of the extension track 333 on the movable track 332, the two can be fixed as one with bolts.

[0042] The stabilizing structure 334 is used to support the bottom of the movable track 332 and the extension track 333 to prevent the movable track 332 from rotating during use, causing the transport vehicle 32 to tilt or derail. As an embodiment, the stabilizing structure 334 includes a support rod 3341, a hydraulic cylinder 3342, a first tooth plate 3343 and a second tooth plate 3344. A slot 3312 is provided at the bottom of the main track 331, one end of the support rod 3341 is clamped in the slot 3312, the other end of the support rod 3341 extends obliquely downward and is clamped in the bolt through hole at the bottom of the drum, the upper end of the support rod 3341 is rotatably connected to the fixed end of the hydraulic cylinder 3342, and the movable end of the hydraulic cylinder 3342 is fixedly connected to the first tooth plate 3343. The second tooth plate 3344 is fixedly arranged at the bottom of the extension track 333, and the second tooth plate 3344 is clamped with the first tooth plate 3343.

[0043] The installation method of the secondary transport device is to first fix the transport vehicle 32 on the movable frame 31, then install the movable frame 31 on the connecting beam 21, then select two sets of transport rails 33, and symmetrically set the two sets of transport regulations 33 on both sides of the movable frame 31, and finally, install the stabilizing structure 334. After the stabilizing structure 334 is installed, the main rail 331, the movable rail 332 and the extension rail 333 are approximately at the same height.

[0044] by Figure 2 For example, when in use, part of the positioning pin 7 is pulled out, so that the positioning pin 7 only fixes the upper chassis 323 and the lower chassis 322 as a whole, and the transport vehicle 32 is pushed to the right, so that the transport vehicle 32 moves to the right along the transport track 33, and the lining plate 8 is close to the right side wall of the drum. When the lining plate 8 is close to the pre-installation position, the push rod motor 3241 is started to push the lining plate 8 to the installation position, and the lining plate 8 is fixed to the drum with bolts. When it is necessary to install the lining plate 8 on the left side wall of the drum, it is only necessary to completely pull out the positioning pin 7, and then rotate the upper chassis 323 180 degrees relative to the lower chassis 322, so as to turn the front of the transport vehicle 32, and then transport and install the lining plate 8 again in the above-mentioned manner, which will not be repeated here.

[0045] Since the liner 8 is heavy, it is difficult to push or pull the transport vehicle 32 loaded with the liner 8 by manpower, and since the transport vehicle 32 is not fixed when the push rod motor 3241 is working, the transport vehicle 32 and the liner 8 will move in the opposite direction, making it impossible to install the liner 8 normally.

[0046] To solve the above problems, please refer to Fig.11 The end of the support rod 3341 away from the main track 331 is fixed with a third pulley 33411, and two second motors 336 are symmetrically arranged above the connecting rod 335. The output shafts of the two second motors 336 are fixedly connected to a winch (not shown in the figure), and two traction rings (not shown in the figure) are respectively installed at the left and right ends of the lower chassis 322. The cable on the winch first passes around the third pulley 33411 and then connects to the traction ring. When in use, the two second motors 336 are started to rotate synchronously, and the cables are retracted at the same time to pull the transport vehicle to a predetermined position.

[0047] The following will introduce the method of using the auxiliary device when installing the liner 8, wherein the installation method and use steps already introduced above will not be repeated below.

[0048] The method of using the assistive device includes the following steps: S1. First, move the connecting beam 21 into the drum, install the movable frame 31 equipped with the transport vehicle 32 onto the connecting beam 21, pass the hook of the overhead crane through the bolt through hole of the drum side wall and introduce it into the overhead crane, lift the connecting beam 21 with the overhead crane, and then install the motor housing 24 to one end of the connecting beam 21 close to the drum mouth.

[0049] S2. Install a walking assembly 1 at each end of the connecting beam 21, adjust the length of the telescopic supporting leg 12 to an appropriate level, fix the position of the telescopic supporting leg 12 with the reinforcing rod 15, push the movable frame 31, and place the transport vehicle 32 at a predetermined axial installation position.

[0050] S3. Then, two sets of transport rails 33 are symmetrically fixed to the bottom of the movable frame 31, thus completing the assembly of the auxiliary device.

[0051] S4. Fix the transport plate 23 on the liner 8, use a crane to lift the transport plate 23 loaded with the liner 8 to the vicinity of the first motor 22, and then use the cable on the winch connected to the first motor 22 to fix the transport plate 23, tighten the cable to make the first motor 22 lift the liner 8.

[0052] S5. Push or pull the first motor 22 to drive the lining plate 8 to move toward the electromagnet 3242, start the electromagnet 3242, make the electromagnet 3242 attract the lining plate 8, and then remove the transport plate 23.

[0053] S6. Adjust the lateral position of the transport vehicle 32 and use the transport vehicle 32 to transport the lining plate 8 to the pre-installation position.

[0054] S7. Fix the liner 8 to the drum with bolts.

[0055] It is understandable that when the liner 8 needs to be disassembled and replaced, it is only necessary to reverse the above steps S4-S7, which will not be described in detail herein.

[0056] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
