Description

Technical Field

[0001] The invention relates to the field of ball mills, and in particular to auxiliary equipment for loading and unloading liner plates of ball mills. 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 hoist 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 200-1500kg, which is difficult to transport by manpower alone. In addition, the working temperature in the drum is above 50°C and the humidity is above 98%.

DETAILED DESCRIPTION

[0023] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] like Figure 1-Figure 15As shown, the present invention discloses a ball mill liner loading and unloading auxiliary equipment (hereinafter referred to as the device), including an adjustable bracket 1, a conveying track 2, a conveying vehicle 3 and a mounting structure 4. The adjustable bracket 1 is used to support the device and enable the device to move along the axial direction of the drum 5 (hereinafter referred to as the drum) in the ball mill drum 5; the conveying track 2 provides a walking track for the conveying vehicle 3; the conveying vehicle 3 is used to convey the liner 7, and transport the liner 7 from the outside of the drum 5 to the position to be installed in the drum 5; the mounting structure 4 can install the liner 7 transported to the drum 5 on the inner wall of the drum 5. The liner 7 includes a liner body 71 and a stud 72, and the stud 72 is fixedly connected to the liner body 71.

[0025] like Figure 2 As shown, the adjustable bracket 1 includes a combined slider 11, a retractable support leg 12 and a caster assembly 13. Two opposite sides of the combined slider 11 are rotatably connected to two retractable support legs 12, the two retractable support legs 12 on the same side are spaced apart from each other, and the retractable support legs 12 on the opposite side are symmetrically arranged, and one end of the retractable support leg 12 away from the combined slider 11 is telescopically connected to the caster assembly 13.

[0026] As a method of rotationally connecting the combined slider 11 and the telescopic support leg 12, the combined slider 11 can be connected to the telescopic support leg 12 via a hinge.

[0027] As an embodiment of a retractable support leg 12, Figure 4 , Figure 6 As shown, the telescopic support leg 12 includes an outer rod 121 and an insertion rod 122. One end of the outer rod 121 is rotatably connected to the combined slider 11, 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 can slide along the length direction of the outer rod 121. The outer rod 121 is provided with a plurality of first through holes 1212, and the insertion rod 122 is provided with a plurality of second through holes corresponding to the positions of the first through holes 1212. When in use, the insertion amount of the insertion rod 122 in the outer rod 121 is adjusted. When the combined length of the insertion rod 122 and the outer rod 121 is appropriate, the first bolt is passed through the first through hole 1212 and the second through hole in sequence, and the first bolt is tightened with a nut, so that the positions of the outer rod 121 and the insertion rod 122 can be fixed.

[0028] As an embodiment of a caster assembly 13, Figure 6 , Figure 7 and Figure 8 As shown, the caster assembly 13 includes two fixed wheel pieces 132, a roller 131 and an air spring 133. The two fixed wheel pieces 132 are symmetrically arranged on both sides of the end of the insertion rod 122, and the two fixed wheel pieces 132 are connected to the end of the insertion rod 122 by a first screw 134. Figure 7 , Figure 8As shown, a square groove 1221 is provided at the end of the plug rod 122, and the square groove 1221 extends along the length direction of the plug rod 122. The first screw 134 passes through the two fixed wheel pieces 132. At this time, the rod body of the first screw 134 is set in the square groove 1221. During use, the rod body of the first screw 134 can slide in the square groove 1221, so that the caster assembly 13 can reciprocate at the end of the plug rod 122 along the length direction of the plug rod 122. The roller 131 is rotatably set between the two fixed wheel pieces 132, such as the roller 131 can be rotatably connected to the fixed wheel piece 132 through a ball bearing, and the roller 131 is not completely covered by the fixed wheel piece 132, so that the roller 131 can contact the inner wall of the drum 5. The air spring 133 is arranged between the caster assembly 13 and the plug rod 122. When the device is in operation, the air spring 133 is in a compressed state. When the pressure between the roller 5 and the caster assembly 13 increases, the air spring 133 is further compressed. When the pressure between the two decreases, the compression amount of the air spring 133 decreases, that is, the air spring 133 can play a certain buffering role. As a way to install the air spring 133, please refer to Figure 8 A square slider 135 is threadedly connected to the rod body of the first screw 134 , and the square slider 135 is slidably set in the square groove 1221 . One end of the air spring 133 is fixedly connected to the side wall of the square slider 135 , and the other end of the air spring 133 is fixedly connected to the side wall of the square groove 1221 .

[0029] The installation method of the caster assembly 13 is as follows: first, one end of the air spring 133 is fixedly connected to the square slider 135, and then the air spring 133 and the square slider 135 are placed in the square groove 1221, and the other end of the air spring 133 is fixed to the side wall of the square groove 1221. First, the roller 131 is installed on a fixed wheel piece 132, and then the fixed wheel piece 132 is placed in the pre-installation position, and then another fixed wheel piece 132 is placed in the pre-installation position and connected to the roller 131. Then, the first screw 134 is screwed so that the first screw 134 passes through the fixed wheel piece 132 and is threadedly connected to the square slider 135.

[0030] Generally, the adjustable bracket 1 is used in a set of two. Figure 1 and Figure 2The installation and use methods are introduced. First, move all the parts of the two adjustable brackets 1 to the inside of the drum 5; then raise the combined slider 11 so that the axis of the combined slider 11 and the axis of the drum 5 roughly coincide; install the caster assembly 13 to the end of the retractable support leg 12; finally, install the retractable support leg 12 on the combined slider 11, and adjust the retractable support leg 12. The length of the retractable support leg 12 is preferably such that the caster assembly 13 contacts the side wall of the drum 5 and the air spring 133 is in a compressed state. After the two adjustable brackets 1 are assembled, one adjustable bracket 1 is close to the mouth of the drum 5, and the other adjustable bracket 1 is located at a deeper position of the drum 5.

[0031] When in use, it is necessary to connect two adjustable brackets 1 into one body, as an implementation method, such as Figure 2 As shown, a socket can be provided on the combined slider 11, and the two ends of the main beam 6 are respectively inserted into the two combined sliders 11. Furthermore, bolts can be used to fix the main beam 6 to the combined slider 11. The shape of the socket corresponds to the shape of the main beam 6. For example, the main beam 6 can be an I-beam, and the socket is in the shape of an I-beam.

[0032] After assembly is completed, one end of the retractable supporting leg 12 is rotatably connected to the combined slider 11, and the other end of the retractable supporting leg 12 is abutted against the roller 5 through the caster assembly 13. During operation, the retractable supporting leg 12 is prone to unnecessary rotation, which seriously affects the working stability of the adjustable bracket 1.

[0033] Therefore, an anti-torque structure can be provided to solve the above problem. As an embodiment, the anti-torque structure can be an anti-torque support rod 14. Figure 2 , Figure 6 and Fig. 9 As shown, two opposite side walls of the outer rod 121 are provided with a slide groove 1211 extending along the length direction thereof, and a connecting block is slidably arranged in the slide groove 1211. Figure 2 As shown, the upper and lower ends of the vertical anti-torque support rod 14 are respectively connected to the upper and lower sliders through second bolts, and the two vertical anti-torque support rods 14 are arranged side by side on both sides of the telescopic support leg 12, and the two anti-torque support rods 14 are connected as a whole through a reinforcement rod 15, that is, the two ends of the reinforcement rod 15 are respectively fixedly connected to the two anti-torque support rods 14. Please continue to refer to Figure 2 The left and right ends of the horizontal anti-torque support rod 14 are connected to the two left and right sliders through the second bolts respectively. Its structure is similar to the vertical anti-torque support rod 14 and will not be described in detail. It should be noted that the anti-torque support rod 14 may not be provided between the two top telescopic support legs 12, in order to reserve space for the installation of the conveying track 2 and the movement of the conveying vehicle 3.

[0034] In order to further improve the connection stability between the two adjustable brackets 1, Figure 2 As shown, adjacent caster assemblies 13 can be connected as a whole by a connecting rod 16. Specifically, an extension block 136 can be welded on the side of the fixed wheel piece 132, and the two extension blocks 136 are arranged opposite to each other, and the two ends of the connecting rod 16 are fixedly connected to the two extension blocks 136 respectively.

[0035] The conveying track 2 is used to transport the lining plate 7 from the drum mouth of the drum 5 to the pre-installation position in the drum 5, such as Figure 2 As shown, the conveying track 2 includes an axial conveying channel 21 and a radial conveying channel 22. Fig.11 and Fig.12 The axial conveying channel 21 includes a main channel 211, and the main channel 211 includes a first bottom plate 2111, which is fixedly arranged above the combined slider 11, and two vertical rails parallel to each other are arranged on the top of the first bottom plate 2111, and the two vertical rails are both in the length direction of the first bottom plate 2111 (i.e. Fig.11 The first bottom plate 2111 is also provided with two parallel transverse rails 2114 on the top. The two transverse rails 2114 extend in the width direction of the first bottom plate 2111 (i.e., the X direction). The spacing between the two transverse rails 2114 is equal to the spacing between the two vertical rails. The track model of the transverse rails 2114 is the same as that of the vertical rails. The transverse rails 2114 and the vertical rails are perpendicular to each other. The vertical rails include a first strip rail 2112 and a rotating rail 2113. Fig.11 For example, the vertical track along the positive direction of the Y axis is the rotating track 2113, the first strip track 2112, the rotating track 2113 and the first strip track 2112. At this time, the positions of the two horizontal tracks 2114 correspond to the positions of the two rotating tracks 2113. The first strip track 2112 is fixedly connected to the first bottom plate 2111, and the rotating track 2113 is rotatably connected to the first bottom plate 2111. Fig.11 and Fig.12 The rotating track 2113 includes a motor 21131, a turntable 21132 and a track body 21133. The motor 21131 is fixedly arranged at the bottom of the first bottom plate 2111. The output shaft of the motor 21131 is fixedly connected to the turntable 21132. The turntable 21132 is embedded in the first bottom plate 2111. The turntable 21132 can rotate freely. The top of the turntable 21132 is fixedly connected to the track body 21133. When the motor 21131 is working, the turntable 21132 is driven to rotate, and the turntable 21132 drives the track body 21133 to rotate. During the rotation process, the track body 21133 can be collinear with the first strip track 2112 or the transverse track 2114.

[0036] When the length of the main channel 211 is too short to meet the transportation distance of the liner 7, the axial conveying channel 21 may further include an extension channel 212, such as Fig.11 As shown, the extension channel 212 includes a second bottom plate 2121 and a second strip track 2122. One end of the second bottom plate 2121 is hinged to the first bottom plate 2111. The other end of the second bottom plate 2121 is fixed by a support device placed outside the discharge port of the drum 5. The support device can be a flange of the discharge port of the drum 5. The support device can also be any existing technology with a support function, such as a support frame, etc. Since the support device is not the content that the present invention intends to protect, it will not be described in detail herein. The two second strip tracks 2122 are fixedly arranged on the top of the second bottom plate 2121. The second bottom plate 2121 is rotated. When the second bottom plate 2121 and the first bottom plate 2111 are coplanar, the second strip track 2122 and the first strip track 2112 are colinear. Obviously, in order to prevent the connection between the second bottom plate 2121 and the first bottom plate 2111 from breaking, a support device can also be placed at the connection between the two.

[0037] The radial delivery channel 22 is arranged on the side of the axial delivery channel 21. Fig.11 As shown, the radial conveying channel 22 includes a conveying channel body 221 and a supporting structure. One end of the conveying channel body 221 is hinged to the first bottom plate 2111, and a blocking bar 2211 is fixedly arranged at the other end of the conveying channel body 221. Baffles 2212 are fixedly arranged on both sides of the conveying channel body 221. The height of the baffles 2212 is higher than the height of the conveying vehicle 3. It should be noted that the extension line of the two transverse rails 2114 is between the two baffles 2212, so as to ensure that the conveying vehicle 3 can smoothly enter the conveying channel body 221 after turning. The supporting structure is used to support the end of the conveying channel body 221 away from the axial conveying channel 21. As an implementation method of the supporting structure, please combine Figure 2 and Fig.11 The supporting structure may be a first electric push rod 222, the movable end of the first electric push rod 222 is rotatably connected to the blocking bar 2211, and the fixed end of the first electric push rod 222 is rotatably connected to the connecting rod 16. Obviously, the first electric push rod 222 may also be rotatably connected to other fixed structures, such as the inner wall of the drum 5. When in use, the first electric push rod 222 is extended or shortened to rotate the conveying channel body 221.

[0038] Preferably, there are two radial conveying channels 22 , which are symmetrically arranged on both sides of the axial conveying channel 21 , so that the conveying vehicle 3 can move to the left and right sides of the drum 5 .

[0039] Please refer to Fig.12The transport vehicle 3 includes a track wheel 31 and a transport bucket 32. The track wheel 31 is adapted to the vertical track and the transverse track 2114, that is, the track wheel 31 can move along the vertical track or the transverse track 2114. The four corners of the bottom of the transport bucket 32 ​​are rotatably connected to the track wheel 31. Fig.17 As shown, the cooperation mode of the track wheel 31 and the transport bucket 32 ​​is similar to the universal wheel of the seat. Specifically, the track wheel 31 and the transport bucket 32 ​​are rotatably connected through the connecting bearing 8. For example, the track wheel 31 can be fixedly connected to the inner ring of the connecting bearing 8, and the transport bucket 32 ​​can be fixedly connected to the outer ring of the connecting bearing 8. The transport vehicle 3 can be powered by electric energy and can be pushed and pulled by manpower. When in use, the liner 7 is placed in the transport bucket 32, and the stud 72 is placed upward.

[0040] Furthermore, if the transport vehicle 3 is powered by electric energy, Fig.17 As shown, the transport vehicle 3 further includes a transmission motor 33 and a transmission gear 34. The transmission motor 33 is fixedly arranged at the bottom of the transport bucket 32. The transmission motor 33 is transmission-connected to the rail wheel 31 through the transmission gear 34. Specifically, the transmission gear 34 includes a first transmission gear 341, a second transmission gear 342, and a third transmission gear 343. The first transmission gear 341 is coaxially fixedly connected to the output end of the transmission motor 33. The first transmission gear 341 and the second transmission gear 342 are meshed. The second transmission gear 342 and the rotating shaft 35 are coaxially fixedly connected. The rotating shaft 35 and the transport bucket 32 ​​are rotationally connected. The second transmission gear 342 and the third transmission gear 343 are meshed. The third transmission gear 343 and the rail wheel 31 are coaxially fixedly connected.

[0041] It should be explained that the terminal of the conveying vehicle 3 is near the pre-installed position of the lining plate 7, that is, the terminal of the conveying vehicle 3 may be in the axial conveying channel 21, or in the radial conveying channel 22. Taking the terminal in the axial conveying channel 21 as an example, the lining plate 7 is first placed in the transport bucket 32, the conveying vehicle 3 is started, and the conveying vehicle 3 first moves along the vertical track. When the conveying vehicle 3 moves to the predetermined position, the conveying vehicle 3 is stopped. When the terminal of the conveying vehicle 3 is in the radial conveying channel 22, the conveying vehicle 3 first walks on the axial conveying channel 21 in the aforementioned manner. At this time, the track body 21133 and the first strip track 2112 are in line. When the four track wheels 31 of the conveying vehicle 3 are all located on the rotating track 2113, the motors 21131 of all the rotating tracks 2113 are started to rotate the rotating track 2113. When the track body 21133 and the transverse track 2114 are in line, the motor 21131 stops working. In this process, the track body 21133 drives the track wheel 31 to turn. The conveying vehicle 3 continues to move, and the conveying vehicle 3 enters the radial conveying channel 22, slides down to the rear end of the radial conveying channel 22 under the action of gravity, and stops after the conveying vehicle 3 collides with the blocking bar 2211. The blocking bar 2211 can prevent the conveying vehicle 3 from colliding with the inner wall of the drum 5 and damaging the inner wall of the drum 5.

[0042] In order to make the transport vehicle 3 stay accurately on the rotating track 2113 and prevent the transport vehicle 3 from leaving the track. Fig.11 As shown, a block 2115 is further provided at one end of the vertical track away from the discharge port of the roller 5, and the block 2115 is fixedly arranged on the top of the first bottom plate 2111, and the width of the block 2115 is greater than the width of the vertical track. When the transport vehicle 3 moves to the block 2115, the block 2115 can block the track wheel 31, thereby preventing the transport vehicle 3 from continuing to move.

[0043] The mounting structure 4 is used to mount the lining plate 7 in the conveying vehicle 3 onto the roller 5. The mounting structure 4 includes a mounting crane 41. The mounting crane 41 is used to hoist the lining plate 7 on the top of the roller 5. Figure 1 and Fig.14 The installation crane 41 includes a traveling frame 411, an electric winch 412 and a hoisting head 413. The traveling frame 411 includes a frame body 4111 and casters 4112. Four casters 4112 are provided at the bottom of the frame body 4111. The traveling frame 411 is arranged at the top of the outer wall of the drum 5. The four casters 4112 are in contact with the outer wall of the drum 5. The traveling frame 411 can move axially along the outer wall of the drum 5. The electric winch 412 is fixedly arranged at the top of the traveling frame 411. The cable 4121 of the electric winch 412 can extend to the bottom of the frame body 4111. The cable 4121 can enter the inside of the drum 5 along the reserved hole 51 on the wall of the drum 5. The reserved hole 51 is used to fix the lining plate 7 on the drum 5. The installation method of the lining plate 7 is roughly as follows: the stud 72 on the lining plate 7 passes through the reserved hole 51, and then the lining plate 7 mounting bolt is screwed into the stud 72, and the head end of the lining plate 7 mounting bolt abuts against the outer wall of the drum 5. The lifting head 413 can more conveniently connect the lining plate 7 to the cable 4121, that is, one end of the lifting head 413 is connected to the cable 4121, and the other end of the lifting head 413 is connected to the lining plate 7. The lifting head 413 can also enter and exit the drum 5 from the reserved hole 51 along with the cable 4121. As an implementation mode, the lifting head 413 is a round rod-shaped structure, and the diameter of the lifting head 413 is smaller than the diameter of the reserved hole 51. A connecting hole 4131 is provided at the top of the lifting head 413. The cable 4121 passes through the connecting hole 4131 and is fastened by the buckle 414, so that the cable 4121 and the top of the lifting head 413 can be connected and fixed; an external thread 4132 is provided at the bottom of the lifting head 413, and the external thread 4132 at the bottom of the lifting head 413 can engage with the internal thread of the stud 72 of the lining plate 7. Generally, the inner diameter of the stud 72 of the lining plate 7 is 70% of the outer diameter.

[0044] The installation crane 41 is used in the following manner: first, the traveling frame 411 is pushed to make the installation crane 41 near the area to be installed of the lining plate 7, and the electric winch 412 is started, the cable 4121 is extended, and the cable 4121 drives the lifting head 413 to enter the inside of the drum 5, and the bottom of the lifting head 413 is threadedly connected with the stud 72 of the lining plate 7. The electric winch 412 is started again, the cable 4121 is shortened, and the cable 4121 drives the lifting head 413 and the lining plate 7 to move upward until the lining plate 7 fits the inner wall of the drum 5, at which time the stud 72 of the lining plate 7 enters the reserved hole 51, and then the lining plate 7 installation bolt is threadedly connected with the lining plate 7 stud 72, and the installation of the lining plate 7 on the top of the drum 5 is completed.

[0045] Obviously, the number of electric winches 412 can be selected according to actual conditions, and it is only necessary to ensure that each electric winch 412 runs roughly synchronously. Fig.14 As shown in the figure, two electric winches 412 are selected in this embodiment, and the two electric winches 412 can be respectively hoisted at both ends of the lining board 7, so as to prevent the lining board 7 from tilting during the hoisting process. It can be understood that the number of electric winches 412 can also be three or more, so as to further improve the stability of the lining board 7 during the hoisting process.

[0046] In the above embodiment, the conveying vehicle 3 can transport the lining plate 7 to the left or right side of the drum 5 along the radial conveying channel 22, and the position of the conveying vehicle 3 can be changed by adjusting the angle of the radial conveying channel 22. However, in actual work, only adjusting the radial conveying channel 22 cannot make the lining plate 7 on the conveying vehicle 3 close to the inner walls of the left and right sides of the drum 5, which requires manual further movement of the lining plate 7, and the lining plate 7 is very heavy and difficult to move.

[0047] To solve the above problem, the mounting structure 4 further includes a flip assembly 42, which is arranged at the rear end of the radial conveying channel 22. The flip assembly 42 can drive the conveying vehicle 3 to move further, so that the lining plate 7 on the conveying vehicle 3 can fit the inner wall of the drum 5. As an embodiment, please refer to Fig.12 and Fig.13, the tail end of the conveying channel body 221 is an open structure, and the flip assembly 42 is arranged at the opening structure. Specifically, the flip assembly 42 includes a support frame 421, a second electric push rod 422 and a flip plate 423. The support frame 421 is fixedly arranged at the bottom of the tail end of the conveying channel body 221, such as one end of the support frame 421 can be fixedly connected to the conveying channel body 221, and the other end of the support frame 421 is fixedly connected to the bottom of the blocking bar 2211. The flip plate 423 is covered at the opening of the tail end of the conveying channel body 221, and one end of the flip plate 423 is hinged to the blocking bar 2211, that is, the flip plate 423 can rotate with the blocking bar 2211 as the rotation axis. The fixed end of the second electric push rod 422 is rotatably connected to the support frame 421, and the movable end of the second electric push rod 422 is rotatably connected to the side of the flip plate 423 away from the blocking bar 2211.

[0048] The flip assembly 42 is used in such a way that, during the transportation of the lining 7, the flip plate 423 and the conveying channel body 221 are roughly located on the same plane, so that the conveying vehicle 3 can move onto the flip plate 423. When the conveying vehicle 3 moves onto the flip plate 423, the second electric push rod 422 is started, and the flip plate 423 drives the conveying vehicle 3 to rotate, so that the lining 7 is close to the inner wall of the drum 5, and then the stud 72 on the lining 7 passes through the reserved hole 51, and then the second electric push rod 422 stops working, and then the lining 7 mounting bolts are used to install the lining 7 on the inner wall of the drum 5.

[0049] The method of using the assistive device includes the following steps: S1, two adjustable brackets 1 are arranged side by side inside the drum 5, and the two are connected as a whole by a main beam 6; S2, installing the conveying track 2 at a predetermined position; S3, installing the mounting structure 4 at a predetermined position; S4, using the conveyor vehicle 3 to transport the lining plate 7 to a predetermined position; S5. Use the mounting structure 4 to mount the lining plate 7 onto the side wall of the drum 5.
