Description

Technical Field

[0001] This invention relates to the field of stainless steel bar stacking technology, specifically to an automatic stainless steel bar stacking device. Background Technology

[0002] After the stainless steel bars are produced, they need to be stacked in order to place them neatly, make the placement of the stainless steel bars more stable, and make efficient use of storage space. When stacking larger stainless steel bars, hoisting equipment is required to lift and move them.

[0003] Chinese patent CN118239272B discloses a stainless steel bar stacking device. It proposes that when picking up materials, because the bars are stuck together, there is no space to fit the gripping part of the hoisting device with the bars. It is necessary to manually separate the bars that are stuck together to make gaps so that the gripping part can be inserted into the gaps.

[0004] This hoisting operation method requires workers to repeatedly separate and separate a large number of stainless steel bars when they are stacked. This not only increases the workload of the workers, but also poses a safety hazard because the hoisting equipment is located near the workers during the operation.

[0005] Therefore, an automatic stacking device for stainless steel bars is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an automatic stacking device for stainless steel bars, including a lifting frame, an electric cylinder fixedly connected to the inner side of the lifting frame, a first motor fixedly connected to the output end of the electric cylinder, a gear fixedly connected to the output end of the first motor, a rack slidably connected to the inner side of the lifting frame, the rack and the gear cooperating, a movable plate fixedly connected to one end of the rack away from each other, a limit rod fixedly connected to one end of the movable plate, the limit rod and the lifting frame slidably connected, a support plate fixedly connected to one end of the right movable plate, a fixed plate fixedly connected to one end of the right movable plate, a moving plate slidably connected to the inner side of the fixed plate, a first spring fixedly connected to one side of the moving plate, the other end of the first spring fixedly connected to the fixed plate, a slot opened on the surface of the rack, a sliding plate rotatably connected to the outer side of the output end of the first motor, the sliding plate and the lifting frame slidably connected, an insert fixedly connected to one side of the sliding plate close to each other, the slot and the insert cooperating;

[0008] Before implementing this invention, ensure that the gear thickness and rack thickness are the same, and ensure that the length of the insert is half the rack thickness. A slot, just large enough to accommodate the moving plate, is provided on the inner side of one movable plate. When using this invention, workers neatly arrange multiple stainless steel bars to be stacked on a table. Then, workers move away from the stainless steel bars and connect the lifting frame to the lifting equipment. The lifting equipment moves the device to a suitable position. At this point, the gear is engaged with the racks on both the upper and lower sides, while the sliding plates and inserts on both the upper and lower sides are not inserted into the slots. The electric cylinder drives the first motor to move downwards. The first motor drives the gear, slide plate, and insert block to move downwards, causing the upper insert block to insert into the slot of the upper rack, thus limiting and fixing one side of the rack and the movable plate. At this time, the gear only meshes with the lower rack. Then, the hoisting equipment drives the device to move, causing the movable plate connected to the lower rack to move outside the plane of one end of the stainless steel rod. At this time, the movable plate is located outside the other end of the stainless steel rod. The gear drives the movable plate connected to the lower rack to move, causing the movable plate to push the stainless steel rod to move, thus moving the other end of the stainless steel rod to the upper part of the support plate. Then, the gear stops rotating. The wheel, through the rising of the gear, drives the lower insert block to rise to the inside of the slot where it is inserted into the lower rack. The upper insert block is pulled out from the slot of the upper rack. At the same time, the gear moves to mesh with the upper rack. The rotation of the gear drives the upper rack and the movable plate connected to it to move until their positions are symmetrical with those of the other rack and movable plate. Then the gear moves down until it returns to its initial position, with half its thickness engaged with the upper rack and half its thickness engaged with the lower rack. At this point, the insert blocks on both sides are not inserted into the slots. The rotation of the gear drives the racks on both sides to move synchronously, allowing the movable plates on both sides to move. The plates are brought closer together, allowing the movable plate to enter the inner side of one side of the movable plate. The movable plate pushes the stainless steel bar, causing it to clamp and fix the stainless steel bar in conjunction with the other side of the movable plate. Then, the hoisting equipment moves the device to the stacking location. The gears rotate, causing the rack and pinion to move away from each other, so that one side of the movable plate moves the fixed plate and the movable plate. Since one side of the stainless steel bar is in close contact with the movable plate, the movement of the movable plate can push one end of the stainless steel bar off the support plate. At this time, the lower sides of both ends of the stainless steel bar are not blocked by the support, so that the stainless steel bar can fall on the stacking location for stacking.

[0009] In other words, during the stacking process, when clamping and fixing the stainless steel bars, a movable plate on one side pushes a moving plate to move, allowing the moving plate to cooperate with the movable plate on the other side to clamp both ends of the stainless steel bars. This eliminates the need for workers to move to the vicinity of the stainless steel bars, manually create gaps between the curved surfaces of the stacked stainless steel bars, and then install lifting devices on the curved surfaces of the stainless steel bars for hoisting. This improves the safety of the device and the convenience of hoisting. Furthermore, because the movable and moving plates are cuboid in shape, multiple stainless steel bars can be clamped at once, making the stacking and hoisting of stainless steel bars more convenient and improving the stacking efficiency of the device.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the outer side of the support plate, an adjusting plate is fixedly connected to the output end of the hydraulic cylinder, and a roller is rotatably connected to the inner side of the adjusting plate;

[0011] When this invention is used, after one side of the movable plate pushes one end of the stainless steel bar to the upper side of the support plate, the hydraulic cylinder drives the adjustment plate to move, so that the adjustment plate drives the roller to move. The movement of the roller, together with the fixed plate, limits one end of the stainless steel bar. Before the stainless steel bar is pushed to be clamped by the movable plate and the moving plate, the movement trajectory of multiple stainless steel bars can be further limited by the roller and the fixed plate.

[0012] In other words, when the stainless steel bar moves, the rollers and the fixing plate limit the curved surface of the stainless steel bar's side, making the movement trajectory of the stainless steel bar more stable. This makes the movement of the stainless steel bar more stable, less prone to angular deviation during movement, and improves the stability of the device's clamping and hoisting.

[0013] Preferably, a connecting block is fixedly connected to one end of the adjusting plate, an inclined frame is slidably connected to one end of the connecting block, a first pressure plate is fixedly connected to the lower side of the inclined frame, the movable plate on the right side is slidably connected to the first pressure plate, and a first pressure pad is fixedly connected to one end of the first pressure plate.

[0014] Before implementing this invention, ensure that the protruding part at one end of the connecting block has the same shape as the groove opened on the inner side of the inclined frame. When this invention is used, the hydraulic cylinder drives the adjusting plate and the roller to move, so that when the roller cooperates with the fixing plate to limit the side curved surface of one end of the stainless steel rod, the movable plate will drive the connecting block to move simultaneously. The connecting block gradually moves to the high point inside the inclined frame, so that the inclined frame moves down under the influence of gravity and the push of the connecting block. The inclined frame drives the first pressure plate and the first pressure pad to move down, so that the first pressure pad can contact the upper curved surface of one end of the stainless steel rod, thereby cooperating with the support plate to further limit the stainless steel rod.

[0015] In other words, during the movement of the stainless steel bar, when the roller moves in conjunction with the fixed plate to limit its movement, it will simultaneously drive the first pressure plate to move downward. The first pressure plate will then drive the first pressure pad to move downward to be close to the upper curved surface of the stainless steel bar. At this time, the support plate is located on the lower side of one end of the stainless steel bar. The first pressure pad, in conjunction with the support plate, further limits the upper and lower sides of the stainless steel bar, thereby further reducing and limiting the space for the stainless steel bar to move. This makes it less likely for the stainless steel bars to squeeze each other, resulting in vertical movement. This makes the movement of the stainless steel bar more stable and improves the stability of the movement of the stainless steel bar when the device is clamped and hoisted.

[0016] Preferably, a connecting cylinder is fixedly connected to the upper side of the first pressure plate, a connecting rod is slidably connected to the inner side of the connecting cylinder, a second pressure plate is fixedly connected to one end of the connecting rod, the movable plate on the left side is slidably connected to the second pressure plate, and a second pressure pad is fixedly connected to the lower side of the second pressure plate.

[0017] Before implementing this invention, ensure that the movable plate on one side has the shape shown in the figure, with a recessed area that can avoid the vertical movement of the connecting rod, so that the movable plate will not restrict the vertical movement of the connecting rod. When this invention is used, when the first pressure plate drives the first pressure pad to press down, it will simultaneously drive the connecting cylinder to move down, so that the connecting cylinder drives the connecting rod to press down, so that the connecting rod drives the second pressure plate and the second pressure pad to move down, so that the second pressure pad cooperates with the table on which the stainless steel rod is placed to limit the upper and lower curved surfaces of the other end of the stainless steel rod.

[0018] That is, when the first pressure plate and the first pressure pad move down, the second pressure plate and the second pressure pad will move down simultaneously. The movement of the second pressure pad, together with the table on which the stainless steel rod is placed, further limits the other end of the stainless steel rod, making it less likely for the other end of the stainless steel rod to bulge due to vertical overlap. This further restricts the movement trajectory of the stainless steel rod, making the movement of the stainless steel rod more stable when clamped, and improving the stability of the device.

[0019] Preferably, a slot is provided on the inner side of the fixed plate, and a card plate is fixedly connected to one end of the movable plate on the right side, and the card plate and the slot are slidably connected;

[0020] In the use of this invention, the movable plate is limited and supported by the rack and the limiting rod, so that the movable plate can limit and support the card plate. The card plate limits the card slot, so that the card slot further limits the position of the fixed plate.

[0021] In other words, by inserting a clamping plate into the inner side of the slot, when the fixed plate moves with the movable plate on one side, the clamping plate further restricts the other end of the slot and the fixed plate. This further restricts the movement trajectory of the fixed plate as it moves with the movable plate, making the movement of the fixed plate more stable. The clamping plate also supports the fixed plate, reducing the pressure on the connection between the movable plate and the fixed plate due to the support of the fixed plate, thus improving the stability of the device.

[0022] Preferably, an arc-shaped plate is rotatably connected to the inner side of the movable plate on the left, and a second motor is fixedly connected to one side of the fixed plate, with the output end of the second motor fixedly connected to the arc-shaped plate;

[0023] Before implementing this invention, ensure that a groove is provided on the inner side of one movable plate to accommodate the rotation of the arc plate, so that the movable plate will not restrict the rotation of the arc plate. When this invention is working, after the stainless steel bar is clamped by the movable plate and the moving plate, the device is lifted by the hoisting equipment. After the device carries the stainless steel bar up, the arc plate is rotated by the second motor. The rotation of the arc plate causes one end of it to abut against the lower side of one end of the stainless steel bar.

[0024] In other words, after the stainless steel bar is lifted by the clamping and following device, the arc plate rotates so that one end of the arc plate abuts against the lower side of one end of the stainless steel bar. This provides further support and limitation to the other end of the stainless steel bar that is not on the upper side of the support plate during hoisting, making the stainless steel bar more stable when the following device moves. When the stainless steel bars are stacked, the arc plate can be rotated back to its original position so that it no longer abuts against one end of the stainless steel bar. This ensures that when the movable plate and the moving plate are separated from the stainless steel bar, the arc plate will not prevent the stainless steel bar from falling, thus improving the stability of the device.

[0025] Preferably, the inner side of the arc-shaped plate is provided with a receiving groove, a second spring is fixedly connected to the inner side of the receiving groove, a friction rubber block is fixedly connected to one end of the second spring, and the friction rubber block and the receiving groove are slidably connected.

[0026] Before implementing the present invention, ensure that one end of the friction rubber block is patterned to increase friction when it comes into contact with the stainless steel rod. When the present invention is used, when the arc plate rotates to the point where it is about to abut against the lower side of one end of the stainless steel rod, the friction rubber block is pushed out by the second spring, so that the friction rubber block abuts against the stainless steel rod before the arc plate, thereby separating the stainless steel rod from the arc plate.

[0027] In other words, when the arc-shaped plate rotates to abut against the lower side of one end of the stainless steel rod, the second spring pushes the friction rubber block to bulge out from the inside of the receiving groove. This causes the friction rubber block to abut against the stainless steel rod before the arc-shaped plate, and the stainless steel rod, in conjunction with the arc-shaped plate, compresses the friction rubber block to increase the coefficient of friction between the stainless steel rod and the friction rubber block. This makes the stainless steel rod more stable when placed on the upper side of the friction rubber block, and the friction rubber block separates the arc-shaped plate from the stainless steel rod, preventing hard contact between them. Consequently, it prevents unnecessary wear on the stainless steel rod caused by hard contact, thus improving the stability of the device in supporting and restricting the stainless steel rod.

[0028] Preferably, a stabilizing block is fixedly connected to the outside of the gear, and a first brush is fixedly connected to one side of the stabilizing block. The first brush works in conjunction with the rack.

[0029] Before implementing this invention, ensure that the height of the stabilizing block and the first brush is lower than that of the slide plate so that the slide plate does not restrict the rotation of the stabilizing block and the first brush. When the invention is used, when the gear moves up and down, it will drive the stabilizing block and the first brush to move up and down, so that the first brush enters and exits between the teeth of the rack. When the gear rotates in the subsequent rotation, it will synchronously drive the stabilizing block and the first brush to rotate, so that the first brush can repeatedly enter and exit the gap between the teeth of the rack, thereby brushing and cleaning the inside of the rack.

[0030] In other words, when the gear moves up and down to switch to mesh with the rack at different positions, the rotation of the gear drives the first brush to rotate, causing the first brush at different positions to repeatedly enter and exit the recesses between the teeth of the rack, thereby brushing and cleaning the rack. This prevents impurities from accumulating on the inside of the rack, which would affect the meshing of the rack and gear, and improves the convenience of cleaning and the stability of operation of the device.

[0031] Preferably, a fixing block is fixedly connected to the inner side of the hoisting frame, and a second brush is fixedly connected to one end of the fixing block. The second brush is used in conjunction with a gear.

[0032] Before implementing this invention, the fixing block only needs to be of a suitable length so that the second brush can enter between the teeth of the gear, and the fixing block does not need to contact the gear. When this invention is used, the fixing block drives the second brush to enter between the teeth of the gear. When the gear moves up and down or rotates, the gear rotates at a moderate and uniform speed, so that the second brush can continuously contact it, thereby enabling the second brush to clean the gear.

[0033] In other words, when the gear moves up and down or rotates, the second brush is long enough to reach between the gear teeth. As the gear rotates or moves up and down, the second brush repeatedly moves in and out between the gear teeth to clean them. This makes it difficult for impurities to adhere to the gear teeth, making the subsequent meshing of the gear with the rack more stable and further improving the stability of the device.

[0034] Preferably, a limiting block is fixedly connected to one end of the rack, the limiting block is fixedly connected to one end of the limiting rod, and a weight-reducing groove is provided on the inner side of one side of the limiting block;

[0035] Before implementing this invention, ensure that the weight and thickness of one limiting block are greater than that of the other limiting block, and that the heavier limiting block is located at the end of the lifting frame structure that is less and lighter. The other limiting block has a weight-reducing groove, which allows for further balancing of the lifting frame, thus eliminating the need for additional balancing of the device on the lifting equipment. When this invention is used, when the rack and limiting rod move to their maximum position, the lifting frame blocks the limiting block, preventing the rack and limiting rod from moving further.

[0036] In other words, by setting different weights for the limit blocks on both sides, the device is balanced, eliminating the need for balancing adjustments on the hoisting equipment, thus improving the ease of use of the device. Furthermore, when the rack and limit rod move to their extreme positions, the limit blocks are limited by the hoisting frame, preventing the rack and limit rod from excessively moving and falling off, thereby improving the stability of the device.

[0037] The advantages of this invention are:

[0038] 1. The automatic stainless steel bar stacking equipment of the present invention, during the stacking process, when clamping and fixing the stainless steel bars, a movable plate is pushed by a movable plate on one side to move, so that the movable plate can cooperate with the movable plate on the other side to directly clamp both ends of the stainless steel bars. This eliminates the need for workers to move to the vicinity of the stainless steel bars, manually create gaps between the curved surfaces of the stacked stainless steel bars, and then install lifting devices on the curved surfaces of the stainless steel bars for hoisting. This improves the safety of the device and the convenience of hoisting. Furthermore, because the movable plate and the movable plate are cuboid in shape, multiple stainless steel bars can be clamped at once, making the stacking and hoisting of stainless steel bars more convenient and improving the stacking efficiency of the device.

[0039] 2. The automatic stacking equipment for stainless steel bars described in this invention limits the movement of the stainless steel bars by using rollers and fixing plates to restrict the curved side surfaces of the stainless steel bars, thereby further restricting and stabilizing the movement trajectory of the stainless steel bars, making the movement of the stainless steel bars more stable, and reducing the likelihood of angular deviation during movement, thus improving the stability of the device's clamping and hoisting.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0052] Specific implementation examples are given below.

[0053] Please see Figures 1 to 9 As shown in the embodiment of the present invention, an automatic stacking device for stainless steel bars includes a lifting frame 1. An electric cylinder 2 is fixedly connected to the inner side of the lifting frame 1. A first motor 3 is fixedly connected to the output end of the electric cylinder 2. A gear 4 is fixedly connected to the output end of the first motor 3. A rack 5 is slidably connected to the inner side of the lifting frame 1. The rack 5 and the gear 4 cooperate. A movable plate 6 is fixedly connected to one end of the rack 5 that is away from each other. A limit rod 7 is fixedly connected to one end of the movable plate 6. The limit rod 7 is slidably connected to the lifting frame 1. The movable plate 6 on the right side... A support plate 8 is fixedly connected to one end of the movable plate 6 on the right side. A fixed plate 9 is fixedly connected to one end of the movable plate 6 on the right side. A movable plate 10 is slidably connected to the inner side of the fixed plate 9. A first spring 11 is fixedly connected to one side of the movable plate 10. The other end of the first spring 11 is fixedly connected to the fixed plate 9. A slot 12 is opened on the surface of the rack 5. A sliding plate 13 is rotatably connected to the outer side of the output end of the first motor 3. The sliding plate 13 is slidably connected to the lifting frame 1. A plug 14 is fixedly connected to the side of the sliding plate 13 that is close to each other. The slot 12 and the plug 14 are used together.

[0054] Before implementing this invention, ensure that the thickness of gear 4 and rack 5 are the same, and ensure that the length of insert 14 is half the thickness of rack 5. A groove is provided on the inner side of one movable plate 6, just large enough to accommodate the movable plate 10. When using this invention, the worker neatly arranges the multiple stainless steel bars 101 to be stacked on a table 102. Then, the worker moves away from the stainless steel bars 101 and connects the hoisting frame 1 to the hoisting equipment. The hoisting equipment moves the device to a suitable position. At this time, gear 4 meshes with the racks 5 on both the upper and lower sides, while the sliding plates 13 and insert 14 on both the upper and lower sides are not inserted into the slots 12. The electric cylinder 2 drives the first motor 3 to move downwards. Machine 3 drives gear 4, slide plate 13, and insert block 14 to move downwards, causing the upper insert block 14 to insert into the slot 12 of the upper rack 5, thereby limiting and fixing one side of the rack 5 and the movable plate 6. At this time, gear 4 only meshes with the lower rack 5. Then, the hoisting equipment drives the device to move, causing the movable plate 6 connected to the lower rack 5 to move outside the plane of one end of the stainless steel rod 101. At this time, the movable plate 10 is located outside the other end of the stainless steel rod 101. Gear 4 drives the movable plate 6 connected to the lower rack 5 to move, causing the movable plate 6 to push the stainless steel rod 101 to move, thus moving the other end of the stainless steel rod 101 to the upper side of the support plate 8, and then stops rotating. The moving gear 4, by rising, drives the lower insert block 14 to rise to the inside of the slot 12 into the lower rack 5. The upper insert block 14 is pulled out from the inside of the slot 12 of the upper rack 5. At the same time, the gear 4 moves to mesh with the upper rack 5. The rotation of the gear 4 drives the upper rack 5 and the movable plate 6 connected to it to move until their positions are symmetrical with the other rack 5 and the movable plate 6. Then the gear 4 moves down until it returns to its initial position, with half its thickness meshing with the upper rack 5 and half its thickness meshing with the lower rack 5. At this time, the insert blocks 14 on both sides are not inserted into the slot 12. The rotation of the gear 4 will drive the racks on both sides to move synchronously, so that the movable plates 6 on both sides... The moving plate 10 moves closer to the other side, allowing it to enter the inner side of the movable plate 6. The movable plate 6 pushes the moving plate 10, which, together with the other movable plate 6, clamps and fixes the stainless steel rod 101. The hoisting equipment then moves the device to the stacking location. The gear 4 rotates, causing the rack 5 to move away from each other, which in turn causes the movable plate 6 to move the fixed plate 9 and the moving plate 10. Since one side of the stainless steel rod 101 is in close contact with the moving plate 10, the movement of the moving plate 10 pushes one end of the stainless steel rod 101 off the support plate 8. At this point, the lower sides of both ends of the stainless steel rod 101 are not blocked by the support, allowing the stainless steel rod 101 to fall onto the stacking location for stacking.

[0055] In other words, during the stacking process, when clamping and fixing the stainless steel bars 101, the movable plate 10 is moved by pushing the movable plate 6 on one side, so that the movable plate 10 can cooperate with the movable plate 6 on the other side to clamp both ends of the stainless steel bars 101. This eliminates the need for workers to move to the vicinity of the stainless steel bars 101, manually create gaps between the curved surfaces of the stacked stainless steel bars 101, and then install lifting devices on the curved surfaces of the stainless steel bars 101 for hoisting. This improves the safety of the device and the convenience of hoisting. Furthermore, because the movable plate 6 and the movable plate 10 are cuboid in shape, multiple stainless steel bars 101 can be clamped at once, making the stacking and hoisting of the stainless steel bars 101 more convenient and improving the stacking efficiency of the device.

[0056] Please see Figure 1 and Figure 7 As shown, a hydraulic cylinder 15 is fixedly connected to the outer side of the support plate 8, an adjusting plate 16 is fixedly connected to the output end of the hydraulic cylinder 15, and a roller 17 is rotatably connected to the inner side of the adjusting plate 16.

[0057] When this invention is used, after the movable plate 6 pushes one end of the stainless steel rod 101 to the upper side of the support plate 8, the hydraulic cylinder 15 drives the adjusting plate 16 to move, so that the adjusting plate 16 drives the roller 17 to move. The movement of the roller 17, together with the fixed plate 9, limits one end of the stainless steel rod 101. Before the stainless steel rod 101 is pushed to be clamped by the movable plate 6 and the moving plate 10, the movement trajectory of the multiple stainless steel rods 101 can be further limited by the roller 17 and the fixed plate 9.

[0058] That is, when the stainless steel bar 101 moves, the roller 17 and the fixing plate 9 limit the side curved surface of the stainless steel bar 101, so that the movement trajectory of the stainless steel bar 101 is further restricted and more stable, making the movement of the stainless steel bar 101 more stable and less prone to angular deviation during movement, thus improving the stability of the device for clamping and hoisting.

[0059] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, one end of the adjusting plate 16 is fixedly connected to a connecting block 18, one end of the connecting block 18 is slidably connected to an inclined frame 19, the lower side of the inclined frame 19 is fixedly connected to a first pressure plate 20, the right side of the movable plate 6 and the first pressure plate 20 are slidably connected, and one end of the first pressure plate 20 is fixedly connected to a first pressure pad 21.

[0060] Before implementing this invention, ensure that the protruding part of one end of the connecting block 18 has the same shape as the groove opened on the inner side of the inclined frame 19. When this invention is used, the hydraulic cylinder 15 drives the adjusting plate 16 and the roller 17 to move, so that when the roller 17 cooperates with the fixing plate 9 to limit the side surface of one end of the stainless steel rod 101, the movable plate 6 will drive the connecting block 18 to move simultaneously. The connecting block 18 gradually moves to the high point inside the inclined frame 19, so that the inclined frame 19 moves down under the influence of gravity and the push of the connecting block 18. The inclined frame 19 drives the first pressure plate 20 and the first pressure pad 21 to move down, so that the first pressure pad 21 can contact the upper side surface of one end of the stainless steel rod 101, thereby cooperating with the support plate 8 to further limit the stainless steel rod 101.

[0061] That is, during the movement of the stainless steel bar 101, when the roller 17 moves and cooperates with the fixing plate 9 to limit its movement, it will simultaneously drive the first pressure plate 20 to move downward. The first pressure plate 20 will drive the first pressure pad 21 to move downward to be close to the upper curved surface of the stainless steel bar 101. At this time, the support plate 8 is located on the lower side of one end of the stainless steel bar 101. The first pressure pad 21, together with the support plate 8, further limits the upper and lower sides of the stainless steel bar 101, so that the space for the movement of the stainless steel bar 101 is further reduced and limited, making it less likely for the stainless steel bars 101 to squeeze each other and cause the phenomenon of up and down movement. This makes the movement of the stainless steel bar 101 more stable and improves the stability of the movement of the stainless steel bar 101 when the device is clamped and hoisted.

[0062] Please see Figure 1 , Figure 2 and Figure 8 As shown, a connecting cylinder 22 is fixedly connected to the upper side of the first pressure plate 20, a connecting rod 23 is slidably connected to the inner side of the connecting cylinder 22, a second pressure plate 24 is fixedly connected to one end of the connecting rod 23, the movable plate 6 on the left side is slidably connected to the second pressure plate 24, and a second pressure pad 25 is fixedly connected to the lower side of the second pressure plate 24.

[0063] Before implementing this invention, ensure that the movable plate 6 on one side has the shape shown in the figure, and has a recessed area that can avoid the vertical movement of the connecting rod 23, so that the movable plate 6 will not restrict the vertical movement of the connecting rod 23. When the invention is used, when the first pressure plate 20 drives the first pressure pad 21 to press down, it will simultaneously drive the connecting cylinder 22 to move down, so that the connecting cylinder 22 drives the connecting rod 23 to press down, so that the connecting rod 23 drives the second pressure plate 24 and the second pressure pad 25 to move down, so that the second pressure pad 25 cooperates with the table 102 on which the stainless steel rod 101 is placed to limit the upper and lower curved surfaces of the other end of the stainless steel rod 101.

[0064] That is, when the first pressure plate 20 and the first pressure pad 21 move down, the second pressure plate 24 and the second pressure pad 25 will move down simultaneously. The downward movement of the second pressure pad 25, in conjunction with the table 102 on which the stainless steel rod 101 is placed, further limits the other end of the stainless steel rod 101, making it less likely for the other end of the stainless steel rod 101 to bulge due to vertical overlap. This further restricts the movement trajectory of the stainless steel rod 101, making the movement of the stainless steel rod 101 more stable when clamped, and improving the stability of the device.

[0065] Please see Figure 2 , Figure 6 and Figure 8 As shown, a slot 26 is provided on the inner side of the fixed plate 9, and a card plate 27 is fixedly connected to one end of the movable plate 6 on the right side. The card plate 27 and the slot 26 are slidably connected.

[0066] When the present invention is used, the movable plate 6 is limited and supported by the rack 5 and the limiting rod 7, so that the movable plate 6 can limit and support the clamping plate 27, and the clamping plate 27 limits the clamping groove 26, so that the clamping groove 26 further limits the position of the fixed plate 9.

[0067] That is, by inserting the clamping plate 27 into the inner side of the clamping slot 26, when the fixed plate 9 moves with the movable plate 6 on one side, the clamping plate 27 further restricts the other end of the clamping slot 26 and the fixed plate 9, thereby further restricting the movement trajectory of the fixed plate 9 as it moves with the movable plate 6, making the movement of the fixed plate 9 more stable. The clamping plate 27 also supports the fixed plate 9, reducing the pressure on the connection between the movable plate 6 and the fixed plate 9 due to the support of the fixed plate 9, thus improving the stability of the device.

[0068] Please see Figure 1 and Figure 9 As shown, an arc-shaped plate 28 is rotatably connected to the inner side of the movable plate 6 on the left, and a second motor 29 is fixedly connected to one side of the fixed plate 9. The output end of the second motor 29 is fixedly connected to the arc-shaped plate 28.

[0069] Before implementing the present invention, ensure that the inner side of the movable plate 6 on one side is provided with a groove that can accommodate the rotation of the arc plate 28, so that when the arc plate 28 rotates, the movable plate 6 will not restrict its rotation. When the present invention is working, after the stainless steel rod 101 is clamped by the movable plate 6 in conjunction with the moving plate 10, the device is lifted by the hoisting equipment. After the device carries the stainless steel rod 101 up, the arc plate 28 is rotated by the second motor 29. Through the rotation of the arc plate 28, one end of it abuts against the lower side of one end of the stainless steel rod 101.

[0070] That is, after the stainless steel rod 101 is lifted by the clamping and following device, the arc plate 28 is rotated so that one end of the arc plate 28 rotates to abut against the lower side of one end of the stainless steel rod 101. Thus, the stainless steel rod 101 is not further supported and limited at the other end on the upper side of the support plate 8 during hoisting, making the stainless steel rod 101 more stable when the following device moves. When the stainless steel rod 101 is stacked, the arc plate 28 can be rotated to its original position and no longer abut against one end of the stainless steel rod 101. Thus, when the movable plate 6 and the moving plate 10 are separated from the stainless steel rod 101, the arc plate 28 will not prevent the stainless steel rod 101 from falling, improving the stability of the device.

[0071] Please see Figure 9 As shown, the inner side of the arc plate 28 is provided with a receiving groove 2801, and a second spring 30 is fixedly connected to the inner side of the receiving groove 2801. One end of the second spring 30 is fixedly connected to a friction rubber block 31, and the friction rubber block 31 and the receiving groove 2801 are slidably connected.

[0072] Before implementing the present invention, ensure that one end of the friction rubber block 31 is patterned to increase friction when it comes into contact with the stainless steel rod 101. When the present invention is used, when the arc plate 28 rotates to the point where it is about to abut against the lower side of one end of the stainless steel rod 101, the friction rubber block 31 is pushed out by the second spring 30, so that the friction rubber block 31 abuts against the stainless steel rod 101 before the arc plate 28, thereby separating the stainless steel rod 101 from the arc plate 28.

[0073] That is, when the arc plate 28 rotates to abut against the lower side of one end of the stainless steel rod 101, the second spring 30 pushes the friction rubber block 31 to protrude from the inside of the receiving groove 2801, so that the friction rubber block 31 abuts against the stainless steel rod 101 before the arc plate 28, and the stainless steel rod 101 and the arc plate 28 work together to squeeze the friction rubber block 31, so as to increase the friction coefficient between the stainless steel rod 101 and the friction rubber block 31, making the stainless steel rod 101 more stable on the upper side of the friction rubber block 31, and separating the arc plate 28 from the stainless steel rod 101 by the friction rubber block 31, so that the stainless steel rod 101 and the arc plate 28 will not make hard contact, thus preventing unnecessary wear of the stainless steel rod 101 due to hard contact, and improving the stability of the device in supporting and restricting the stainless steel rod 101.

[0074] Please see Figure 4 As shown, a stabilizing block 32 is fixedly connected to the outside of the gear 4, and a first brush 33 is fixedly connected to one side of the stabilizing block 32. The first brush 33 and the rack 5 are used in conjunction.

[0075] Before implementing this invention, ensure that the height of the stabilizing block 32 and the first brush 33 is lower than that of the sliding plate 13 so that the sliding plate 13 does not restrict the rotation of the stabilizing block 32 and the first brush 33. When the invention is used, when the gear 4 moves up and down, it will drive the stabilizing block 32 and the first brush 33 to move up and down, so that the first brush 33 enters and exits between the teeth of the rack 5. When the gear 4 rotates in the future, it will synchronously drive the stabilizing block 32 and the first brush 33 to rotate, so that the first brush 33 can repeatedly enter and exit the gap between the teeth of the rack 5, thereby brushing and cleaning the inside of the rack 5.

[0076] That is, when the gear 4 moves up and down to switch to mesh with the rack 5 at different positions, the rotation of the gear 4 drives the first brush 33 to rotate, so that the first brush 33 at different positions repeatedly enters and exits the recess between the teeth of the rack 5, thereby brushing and cleaning the rack 5. This makes it less likely for impurities to accumulate on the inside of the rack 5, which would affect the meshing of the rack 5 and the gear 4, thus improving the convenience of cleaning and the stability of operation of the device.

[0077] Please see Figure 3 As shown, a fixing block 34 is fixedly connected to the inner side of the hoisting frame 1, and a second brush 35 is fixedly connected to one end of the fixing block 34. The second brush 35 is used in conjunction with the gear 4.

[0078] Before implementing this invention, the fixing block 34 only needs to be of a suitable length so that the second brush 35 can enter between the teeth of the gear 4, and the fixing block 34 does not need to contact the gear 4. When this invention is used, the fixing block 34 drives the second brush 35 to enter between the teeth of the gear 4. When the gear 4 moves up and down or rotates, the gear 4 rotates at a moderate and uniform speed, so that the second brush 35 can continuously contact it, thereby enabling the second brush 35 to clean the gear 4.

[0079] That is, when gear 4 moves up and down or rotates, the length of the second brush 35 is sufficient to extend between the teeth of gear 4. Thus, when gear 4 rotates or moves up and down, the second brush 35 repeatedly enters and exits between the teeth of gear 4, thereby contacting and cleaning them. This makes it difficult for impurities to adhere to the teeth of gear 4, making the subsequent meshing of gear 4 with rack 5 more stable and further improving the stability of the device.

[0080] Please see Figure 1 and Figure 2 As shown, a limiting block 36 is fixedly connected to one end of the rack 5, and the limiting block 36 is fixedly connected to one end of the limiting rod 7. A weight-reducing groove 37 is provided on the inner side of the limiting block 36 on one side.

[0081] Before implementing the present invention, ensure that the weight and thickness of one side limit block 36 are greater than that of the other side limit block 36, and that the heavier limit block 36 is located at the end of the lifting frame 1 with fewer and lighter structures. The other side limit block 36 has a weight reduction groove 37, which can further balance the lifting frame 1, so that the device does not need to be balanced on the lifting equipment. When the present invention is used, when the rack 5 and the limit rod 7 move to the maximum position, the limit block 36 is blocked by the lifting frame 1, so that the rack 5 and the limit rod 7 will not continue to move.

[0082] That is, by setting different weights for the limit blocks 36 on both sides, the device is balanced, thus eliminating the need for balancing adjustments on the hoisting equipment, which improves the ease of use of the device. When the rack 5 and the limit rod 7 move to their extreme positions, the limit block 36 is limited by the hoisting frame 1, which makes it less likely for the rack 5 and the limit rod 7 to move excessively and fall off, thus improving the stability of the device.

[0083] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
