[0033] The embodiment of the present application discloses an auxiliary roll changing device for an electrode sheet roll press.
[0034] Please refer to Figure 1 An embodiment of the auxiliary roll changing device for the electrode sheet roll press provided in the embodiment of the present application comprises: a boom 1, a fixed seat 2 and a lifting arm 3;
[0035] The fixed seat 2 is connected with the boom 1, and the fixed seat 2 is used for supporting the boom 1, and the bottom of the fixed seat 2 is used for connecting with the top of the roll press;
[0036] The axis of the boom 1 is parallel to the axes of the roll 4 and the bending roll seat 5 in the roll press;
[0037] The end of the boom 1 is used for hanging with the roll 4 of the roll press.
[0038] One end of the boom 3 is slidably connected to the middle of the derrick 1, and the other end of the boom 3 is used to be connected to the bending roller seat 5 arranged outside the compression roller.
[0039] It can be understood that, when the roll changing operation is performed, the one end of the boom 3 is first connected to the bending roller seat 5, and since the other end of the boom 3 is slidably connected to the derrick 1, the boom 3 can be pushed to move in a direction away from the roller press, thereby driving the bending roller seat 5 to be separated from the rolling roller 4, and the disassembly of the bending roller seat 5 is completed; then the end of the derrick 1 is connected to the rolling roller 4, and the auxiliary lifting disassembly of the rolling roller 4 is realized. Therefore, the auxiliary roll changing device arranged above the compression roller machine is used to realize the auxiliary step-by-step disassembly of the bending roller seat 5 and the rolling roller 4, the operation is simple, the roll changing efficiency is improved, and the difficulty of the roll changing operation is reduced.
[0040] In a more specific embodiment, the end of the boom 3 used to be connected to the bending roller seat 5 is arranged above the derrick 1, the end of the boom 3 used to be connected to the bending roller seat 5 is provided with a small hoist 11, and the end of the derrick 1 used to be connected to the rolling roller 4 is provided with a large hoist 10. It can be understood that, since the weight of the rolling roller 4 is greater than that of the bending roller seat 5, the large hoist 10 is larger in size than the small hoist 11, and the large hoist 10 is arranged on the derrick 1 which has a stronger carrying capacity, while the small hoist 11 is arranged on the boom 3 which has a smaller carrying capacity. When the bending roller seat 5 is disassembled, the small hoist 11 needs to be disassembled first, and then the large hoist 10 can be installed.
[0041] In a more specific embodiment, the large hoist 10 is an electric hoist. It can be understood that, in specific implementation, the large hoist 10 is used to realize the automatic lifting of the rolling roller 4 during the lifting operation, which saves manpower and improves the disassembly efficiency of the rolling roller 4 compared with a manual electric hoist.
[0042] In a more specific embodiment, the boom 3 is connected to the derrick 1 through a sliding assembly 8; the middle of the boom 3 is rotatably connected to the sliding assembly 8, and the end of the boom 3 connected to the derrick 1 is detachably connected to the sliding assembly 8 at different heights, which is used to adjust the inclination angle of the boom 3 and thereby adjust the height of the end of the boom 3 used to be connected to the bending roller seat 5.
[0043] It can be understood that in specific implementation, the middle part of the boom 3 is rotatably connected with the sliding assembly 8, and the end of the boom 3 connected with the jib 1 is detachably connected with the sliding assembly 8 at different heights, so as to adjust the height of the end of the boom 3 connected with the jib 1, and further change the inclination angle of the boom 3, drive the height of the end of the boom 3 connected with the bending roll seat 5, and flexibly change the distance between the end of the boom 3 and the end of the jib 1. When the bending roll seat 5 is disassembled, the small hoist 11 is directly lifted with the end of the boom 3, so that the end of the jib 1 has enough space to install the large hoist 10, so that after the bending roll seat 5 is disassembled, the process step of disassembling the small hoist 11 is saved, and the disassembly efficiency of the whole roller press is further improved.
[0044] In a more specific embodiment, the end of the end of the boom 3 connected with the jib 1 is provided with a hook 31, the sliding assembly 8 includes an inner sliding part 81 and an outer sliding part 82, the distance between the inner sliding part 81 and the outer sliding part 82 can be changed to be close or far away, the inner sliding part 81 is provided with a first horizontal rod 811 and a second horizontal rod 812 for connecting with the hook 31, the first horizontal rod 811 is higher than the second horizontal rod 812, and the middle part of the boom 3 is rotatably connected with the outer sliding part 82.
[0045] It can be understood that after the hook 31 falls off from the first horizontal rod 811, it hooks the second horizontal rod 812. The specific implementation process is that the boom 3 rotates around the outer sliding part 82, the hook 31 at the end of the boom 3 falls off from the first horizontal rod 811, the inner sliding part 81 is moved close to the outer sliding part 82, the distance between the inner sliding part 81 and the outer sliding part 82 is shortened, so that the hook 31 at the end of the boom 3 can reach the second horizontal rod 812. Therefore, in this embodiment, the hook 31 is arranged at the end of the boom 3, and the first horizontal rod 811 and the second horizontal rod 812 matched with the hook 31 are arranged, so that the hook 31 can be separated from the first horizontal rod 811 and hooked on the second horizontal rod 812 by rotating the boom 3, without the need of other tools to disassemble and install the boom 3 and the sliding assembly 8, and further adjust the height of the end of the boom 3 and adjust the inclination angle of the boom 3, thereby improving the efficiency of adjusting the inclination of the boom 3. In this embodiment, the inner sliding part 81 and the outer sliding part 82 with adjustable spacing are arranged, which can adapt to the situation that the length of the boom 3 projected on the jib 1 becomes shorter when the hook 31 is switched from being connected with the first horizontal rod 811 to being connected with the second horizontal rod 812, so that the hook 31 can be smoothly transferred from the first horizontal rod 811 to the second horizontal rod 812. After the hook 31 falls off from the first horizontal rod 811, it hooks the second horizontal rod 812. The specific implementation process is that the boom 3 rotates around the outer sliding part 82, the hook 31 at the end of the boom 3 falls off from the second horizontal rod 812, the inner sliding part 81 is moved away from the outer sliding part 82, the distance between the inner sliding part 81 and the outer sliding part 82 is increased, so that the hook 31 at the end of the boom 3 can hook the first horizontal rod 811.
[0046] In a more specific embodiment, the inner arc surface of the curved portion of the hook 31 is in contact with the bottom of the first horizontal rod 811. It can be understood that in specific implementation, the opening direction of the hook 31 is arranged upward, and the inner arc surface of the curved portion of the hook 31 has the strongest bearing capacity. Since the end of the boom 3 connected with the bending roller seat 5 is subjected to a downward pulling force during work, the first horizontal rod 811 will generate a downward force on the boom 3 to maintain the lever balance state of the boom 3. Since the bottom of the hook 31 is in contact with the bottom of the first horizontal rod 811 in the embodiment, the force of the first horizontal rod 811 is borne by the bottom of the hook 31, and the bottom of the hook 31 has stronger bearing capacity than other parts of the hook 31, so that the stability of the boom 3 is stronger when the bending roller seat 5 is disassembled by using the boom 3.
[0047] In a more specific embodiment, the first horizontal rod 811 is arranged above the boom 1, and the second horizontal rod 812 is arranged below the boom 1. It can be understood that in specific implementation, through such a layout, the maximum adjustment range of the inclination angle of the boom 3 can be satisfied, and the end of the boom 3 connected with the bending roller seat 5 can be easily lifted to a height that can provide an operation space for lifting the bending roller by the boom 1. In addition, the overall height of the auxiliary roll changing device can be designed to be low, so as to reduce the transportation cost in terms of the overall height of the equipment as much as possible.
[0048] In a more specific embodiment, the sliding assembly 8 comprises a rolling structure 83, and the sliding assembly 8 is connected with the boom 1 through the rolling structure 83. It can be understood that in specific implementation, the relative movement between the sliding assembly 8 and the boom 1 is realized through the rolling structure 83. When the boom 3 is pushed, the force required to overcome the friction between the sliding assembly 8 and the boom 1 is greatly reduced, and the movement efficiency of the boom 3 during work is improved, thereby improving the efficiency of disassembling the bending roller seat 5 by moving the boom 3.
[0049] In a more specific embodiment, the rolling structure 83 comprises a roller, which can generally bear a large load. In some more specific embodiments, the rolling structure 83 comprises a ball. It can be understood that the contact area between the ball and the boom 1 is small, the frictional resistance is small, and the operation is more stable.
[0050] In a more specific embodiment, the first cross bar 811 and the second cross bar 812 are rotatably connected with the rolling structure 83, the rolling surface of the rolling structure 83 of the first cross bar 811 abuts against the upper surface of the boom 1, the rolling surface of the rolling structure 83 of the second cross bar 812 abuts against the lower surface of the boom 1, the two ends of the first cross bar 811 are connected with the two ends of the second cross bar 812 through the connecting rod 85, the first connecting rod 85 and the second connecting rod 85 are respectively arranged on the left and right sides of the boom 1, and are used for locking the distance between the first cross bar 811 and the second cross bar 812 to make the rolling structure 83 on the first cross bar 811 and the second cross bar 812 abut against the boom 1. It can be understood that, in specific implementation, since the force of the boom 3 on the moving assembly is upward when the bending roll seat 5 is disassembled by moving the boom 3, and the self weight of the moving assembly is downward, the first cross bar 811 and the second cross bar 812 are connected through the connecting rod 85 arranged on the left and right sides of the boom 1, the distance between the first cross bar 811 and the second cross bar 812 is fixed, the rolling structure 83 on the first cross bar 811 and the second cross bar 812 abuts against the upper and lower surfaces of the boom 1, and the rolling structure 83 on the lower surface of the boom 1 supports downward and the rolling structure 83 on the upper surface limits downward, so that the moving assembly can keep the sliding assembly 8 stable on the boom 1 and stably move whether the force is downward or upward.
[0051] In a more specific embodiment, the outer sliding piece 82 includes a third cross bar 821 and a fourth cross bar 822, the third cross bar 821 and the fourth cross bar 822 are rotatably connected with the rolling structure 83, the rolling surface of the rolling wheel of the third cross bar 821 abuts against the upper surface of the boom 1, the rolling surface of the rolling wheel of the fourth cross bar 822 abuts against the lower surface of the boom 1, the two ends of the third cross bar 821 are connected with the two ends of the fourth cross bar 822 through the connecting rod 85, the connecting rod 85 is respectively arranged on the left and right sides of the boom 1, and the middle part of the boom 3 is rotatably connected with the third cross bar 821. It can be understood that, through the same structure of the outer sliding piece 81 and the inner sliding assembly 8, the stability of the lifting sliding assembly 8 is ensured.
[0052] In a more specific embodiment, the middle part of the boom 3 is provided with a through hole, the through hole penetrates into the third cross bar 821 to realize the rotatable connection between the middle part of the boom 3 and the third cross bar 821.
[0053] In a more specific embodiment, two parallel hangers 1 are arranged on the fixed seat 2, two rolling structures 83 are arranged on the first cross rod 811, the second cross rod 812, the third cross rod 821 and the fourth cross rod 822 respectively, and the first connecting rod 85, the second connecting rod 85, the third connecting rod 85 and the fourth connecting rod 85 are respectively arranged outside the two hangers 1. The middle part of the hanger arm 3 is arranged between the two rolling structures 83 on the third cross rod 821, and the end of the hanger arm 3 connected with the hanger 1 is arranged between the two rolling structures 83 on the first cross rod 811 or the second cross rod 812. It can be understood that, in specific implementation, on the one hand, the two hangers 1 share the force from the bending roller seat 5 and the rolling roller 4, and the two rolling structures 83 arranged on each cross rod are respectively in abutment with the two hangers 1, so as to improve the balance and stability of the overall sliding of the moving assembly. On the other hand, the actual distance between the hangers of the two ends of the bending roller seat 5 and the rolling roller 4 is very short. When one hanger 1 is arranged, the hanger 1 is located directly below the hanger arm 3, and when the hanger arm 3 is connected with the bending roller seat 5, the hanger 1 will hinder the connection of the hanger arm 3 and the bending roller seat 5. Therefore, by arranging two parallel hangers 1, the hanger arm 3 is located between the two hangers 1 and above the hangers 1, so that the hanger arm 3 is not affected by the hangers 1 when the hanger arm 3 is disassembled from the bending roller seat 5, and has sufficient working space.
[0054] In a more specific embodiment, the two hangers 1 are connected through a connecting plate 9, the connecting plate 9 is symmetrically provided with two through holes, the two connecting rods 85 are respectively fixedly connected with the connecting plate 9 by penetrating through the two through holes, and the connecting plate 9 is provided with a hanging hole in the middle part, which is used for connecting a hook of a large-scale chain block hoist 10, so as to realize that the two hangers 1 simultaneously bear the force from the large-scale chain block hoist 10, and improve the overall carrying capacity of the auxiliary equipment.
[0055] In a more specific embodiment, the hanger arm 3 includes a first sub-hanger arm 323 and a second sub-hanger arm 333 arranged in parallel with each other, one end of the first sub-hanger arm 323 and the second sub-hanger arm 333 is connected to the first cross rod 811 or the second cross rod 812 through a hook 31, and the other end of the first sub-hanger arm 323 and the second sub-hanger arm 333 is connected with each other and used for being connected with the bending roller seat 5. It can be understood that, by connecting the first sub-hanger arm 323 and the second sub-hanger arm 333 with the first cross rod 811 or the second cross rod 812 in parallel, the force of the hanger arm 3 on the cross rod is dispersed, the point of action of the hanger arm 3 on the first cross rod 811 is not concentrated in one place, and the working process of the bending roller seat 5 is more stable.
[0056] In a more specific embodiment, the middle parts of the first sub-hanger arm 323 and the second sub-hanger arm 333 are connected through a cross piece. It can be understood that, in specific implementation, the first sub-hanger arm 323 and the second sub-hanger arm 333 are connected into a whole through the cross piece, so as to improve the synchronization of the first sub-hanger arm 323 and the second sub-hanger arm 333 during work, and further improve the stability of the hanger arm 3 during work.
[0057] In a more specific embodiment, two fixed seats 2 are included, the two fixed seats 2 are symmetrically arranged, a through hole is arranged in the middle of the fixed seat 2, the through hole is used for passing the suspender 1, the suspender 1 is fixed on the fixed seat 2; the fixed seat 2 is arranged between the connecting plate 9 and the sliding assembly 8, it can be understood that, in specific implementation, the fixed seat 2 is used for supporting the whole auxiliary roll changing device, and is also used for limiting the moving range of the sliding assembly 8, so as to avoid that the sliding assembly 8 slides out of the suspender 1 and causes an accident.
[0058] It should be noted that the auxiliary roll changing device in the embodiment is symmetrically arranged with two sets of lifting arms 3, two sets of sliding assemblies 8 and two small hoist winches 11 and two large hoist winches 10 on the suspender 1, it can be understood that, in specific implementation, the lifting arms 3 and the small hoist winches 11 at two ends are respectively hung on the bending roll seats 5 on the two sides of the pole press roller, and the dismounting work of the bending roll seats 5 on the two sides is simultaneously completed, and the dismounting efficiency is obviously improved; the large hoist winches at two ends of the suspender 1 are respectively connected with the rollers 4 at two ends, and the dismounting of the press roller is completed under the simultaneous lifting action of the two large hoist winches 10.
[0059] The specific working principle of the auxiliary roll changing device in the embodiment is as follows:
[0060] When the dismounting work is not needed: when the press roller machine normally operates or in the transportation process, the lifting arm 3 can be to the A position, the back of the hook 31 is abutted with the surface of the first horizontal rod 811, so that the hook 31 is kept in a nearly horizontal state, which can effectively reduce the height of the auxiliary roll changing device and does not affect the overall height of the equipment.
[0061] When the roller 4 needs to be dismounted for grinding, the bending roll seat 5 is first dismounted by the auxiliary roll changing device: first, the hook 31 at the end of the lifting arm 3 is hooked into the first horizontal rod 811 of the moving assembly. At this time, the lifting arm 3 is in the C position, a larger horizontal cantilever distance can be obtained (the bending roll seat 5 is arranged on the outside of the roller 4, so a larger horizontal cantilever distance is needed to perform the dismounting work), at this time, the small hoist winch 11 is hung on the hanging end of the lifting arm 3, then the lifting belt or steel cable of the small hoist winch 11 is used to connect the bending roll seat 5, in the operation process, the lifting arm 3 can move horizontally along the suspender 1, so that the bending roll seat 5 is disconnected from the end of the roller 4 under the tension, and the dismounting work of the bending roll seat 5 is completed.
[0062] After the bending roll seat 5 is dismounted, the roller 4 is dismounted:
[0063] First, the hook 31 at the end of the boom 3 is hooked to the second cross bar 812 of the moving assembly, at this time the boom 3 is in position B, a larger vertical lifting space can be obtained (the 10-ton capacity of the large hoist 10 is relatively large when the roller 4 is disassembled, and more vertical operating space is required, so a larger vertical lifting space is required.), the large hoist 10 is suspended on the connecting plate 9 of the boom 1, the large hoist 10 is used to assist the disassembly and assembly operation by lifting the roller 4, and finally the roller 4 is lifted to the trailer 6, the trailer 6 is slid on the supporting rail 7 to move out of the roller press, and the disassembly and transportation of the roller 4 are completed. The large hoist 10 can select a synchronous lifting electric hoist for the roller 4 to save operation time and reduce the labor intensity of the operator.
