Description

Technical Field

[0002] Large metal sheets generally refer to metal sheets that are larger in size and relatively thinner in thickness. Such sheets are widely used in many industries, such as automobile manufacturing, construction, shipbuilding, aerospace and other fields. Before processing, the metal sheets need to be moved from the storage area to the processing area. Gantry lifting has the advantages of stable structure, strong load-bearing capacity and wide application range. It is a common way to transport large metal sheets. The gantry hoist uses magnets to transport large metal sheets. However, due to the large size of large metal sheets, the existing gantry hoists can only adsorb the middle of the metal sheets and cannot support the two sides of the metal sheets. As a result, when the gantry hoist is transporting the metal sheets, the two sides of the metal sheets are bent downward due to gravity. The metal sheets are in a bent state for a long time during the transportation process, which can easily cause deformation of the two sides of the metal sheets, resulting in a reduction in the self-strength of the metal sheets.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] The existing gantry hoist can only adsorb the middle part of the metal sheet but cannot support the two sides of the metal sheet. As a result, when the gantry hoist is transporting the metal sheet, the two sides of the metal sheet are bent downward due to gravity. The metal sheet is in a bent state for a long time during the transportation process, which can easily cause deformation of the two sides of the metal sheet, thereby reducing the strength of the metal sheet itself.

[0032] Example 1: A deformation-proof lifting device for large plate processing, Figure 1-Figure 5As shown, it includes a base 1, the top of the base 1 is slidably connected to a sliding seat 2 through a slider on an electric slide rail, the lower plane of the sliding seat 2 is fixedly connected to two first motors 3 distributed in front and behind mirror images, the output shaft of the first motor 3 is fixedly connected to a first roller 4 rotatably connected to the sliding seat 2, and a steel cable is fixedly connected between the two first rollers 4 distributed in front and behind mirror images, and an adsorption electromagnetic seat 5 is suspended on the steel cable. The adsorption electromagnetic seat 5 is used for electromagnetic adsorption of metal sheets, and two pulleys 6 distributed in front and behind mirror images are provided on the adsorption electromagnetic seat 5. The steel cable is wound around the two pulleys 6 distributed in front and behind mirror images, so that the steel cable suspends the adsorption electromagnetic seat 5 in the air, and the adsorption electromagnetic seat 5 is fixedly connected to two groups of second motors 7 distributed in front and behind mirror images, each group includes two second motors 7, and the output shaft of the second motor 7 is fixedly connected to a first gear 8. The adsorption electromagnetic seat 5 is slidably connected to two groups of first rack racks 9 distributed in front and behind mirror images, each group includes two first rack racks 9, and two adjacent first rack racks 9 are staggered. The two first rack racks 9 are meshed with the adjacent first gears 8, and the output of the second motor 7 The output shaft drives the adjacent first rack 9 to move through the adjacent first gear 8. The middle part of the adsorption electromagnetic seat 5 is fixedly connected with two groups of second rack racks 10 distributed in front and behind mirror images, each group includes two second rack racks 10, and the first rack rack 9 is rotatably connected with the second gear 11 of the linear array. The first rack rack 9 drives the second gear 11 of the linear array thereon to move synchronously, and the second gears 11 of the linear array are all fixedly connected with the support rod 12, and the second gears 11 of the linear array are all in transmission cooperation with the adjacent second rack rack 10. The second gears 11 of the linear array are all in contact and meshing with the adjacent second rack rack 10, so that the second gear 11 drives the support rod 12 thereon to deflect 90°, so that the support rod 12 is deflected from the middle part of the metal sheet to its lower side, and the support rod 12 slides along the edge of the metal sheet to its two sides, and the two sides of the metal sheet are supported and fixed to avoid the two sides of the large metal sheet being unable to bear force, resulting in the two sides of the plate falling and deforming due to gravity. A limiting component for limiting the rotation of the support rod 12 thereon is provided on the first rack rack 9.

[0033] Comparison Figure 6 As shown, the limit assembly includes a first limit block 201 in a linear array, and the first limit blocks 201 in the linear array are all fixedly connected to the adjacent first rack frame 9. The first limit block 201 is used to prevent the adjacent support rod 12 from excessive deflection. The first rack frame 9 is fixedly connected with a second limit block 202 in a linear array, and the second limit block 202 is used to hinder the adjacent support rod 12 to ensure that the support rod 12 is stably deflected by 90°. The first limit block 201 and the adjacent second limit block 202 are vertically distributed with respect to the center of the adjacent second gear 11. The first limit block 201 and the second limit block 202 are both magnetic, and the first limit block 201 and the second limit block 202 are both limited and cooperated with the adjacent support rod 12.

[0034] When it is necessary to lift a large plate, the staff operates the electric slide rail on the base 1, and drives the sliding seat 2 thereon to slide to the top of the plate to be lifted through the slider thereon, and then turns on the two first motors 3. The output shafts of the first motors 3 respectively drive the adjacent first rollers 4 to rotate, and the two first rollers 4 begin to release the steel cables thereon. At this time, the adsorption electromagnetic seat 5 begins to descend, and this continues until the adsorption electromagnetic seat 5 descends to fit the plate at its bottom, and then turns off the two first motors 3 and turns on the adsorption electromagnetic seat 5. At this time, the adsorption electromagnetic seat 5 stops descending and adsorbs the plate below it, and then turns on the two first motors again. The machine 3 makes the two first rollers 4 rotate in opposite directions to reel in the steel cables thereon. At this time, the steel cables pull the plate to move upward synchronously through the adsorption electromagnetic seat 5. When the suspended plate is separated from the plate at its bottom, the two second motors 7 located on the top are turned on. At this time, the four first racks 9 are located in the middle of the plate. The output shafts of the two second motors 7 drive the first gears 8 thereon to rotate. The first gears 8 drive the adjacent first racks 9 to move along the adsorption electromagnetic seat 5, so that the two first racks 9 on the top move from the middle of the plate to the front side. The movement of the first racks 9 drives the second gears 11 of the linear array thereon to move synchronously. When the second gear 11 of the linear array is in contact and meshing with the adjacent second rack frame 10, the second gear 11 deflects 90°, and the support rod 12 separates from the adjacent first limit block 201, and this continues until the support rod 12 synchronously deflects 90° and fits with the adjacent second limit block 202 and adsorbs each other. Since the two second rack frames 10 are located below the adsorption electromagnetic seat 5, the support rod 12 is rotated to a vertical state of the plate due to the parallel state of the plate, and is located on the lower side of the plate. Then the first rack frame 9 drives the support rod 12 deflected to the bottom of the plate to slide along the edge of the middle part of the plate to the front side of the plate, so that the linear array The support rods 12 of the linear array support the plate, and then the two second motors 7 located at the top are turned off, and the two second motors 7 located at the bottom are turned on at the same time, and the above steps are repeated to make the two first racks 9 located at the bottom move from the middle to the rear side, and the support rods 12 thereon slide along the edge of the middle of the plate to the rear side of the plate, and by deflecting the support rods 12 from the middle of the plate to the bottom thereof, and then sliding the support rods 12 along the edge of the plate to both sides, the support rods 12 of the linear array support both sides of the plate, thereby preventing the plate from being too large and unable to bear force on both sides of the plate, causing both sides of the plate to fall and deform due to gravity.

[0035] When the support on both sides of the plate is completed, the output shafts of the two first motors 3 drive the adjacent first rotating rollers 4 to continue to reel in the steel cable, so that the adsorption electromagnetic seat 5 drives the plate to move to the required height, and then the two first motors 3 are turned off, and then the electric slide rails on the base 1 are turned on, so that it drives the sliding seat 2 to slide slowly along the base 1, and the sliding seat 2 drives the plate to move synchronously and slowly through the first rotating rollers 4, the steel cable and the adsorption electromagnetic seat 5, until the plate moves to the required position, the electric slide rails on the base 1 are turned off, and then the two first motors 3 are turned on, and the output shaft of the first motor 3 drives the first rotating roller 4 to rotate and release the steel cable. At this time, the adsorption electromagnetic seat 5 drives the plate thereon to move downward, and so on until it moves to the top of the required position, and then the two second motors 7 located below are turned on, and the output shaft of the second motor 7 drives the first gear 8 thereon to rotate in the opposite direction, so that the two adjacent first rack racks 9 distributed in a mirror image are reset, and the first rack rack 9 drives the linear array thereon The second gear 11 contacts the adjacent second rack rack 10, so that the second gear 11 drives the support rod 12 thereon to reset and rotate, so that the support rod 12 is separated from the adjacent second limit block 202, and is reset by deflection from the bottom of the plate, so that the support rod 12 contacts the adjacent first limit block 201, and then the two second motors 7 located at the bottom are turned off, and at the same time, the two second motors 7 located at the top are repeated, and the two first rack racks 9 located at the bottom are slid from the front side to the middle of the plate for reset. At this time, the two sides of the plate lack support and gradually fit with the platform below, so that both sides of the plate fall to the platform, and then the adsorption electromagnetic seat 5 is turned off. At this time, the middle part of the plate falls to the platform, and then the mirror-distributed first motor 3 is turned on, and the output shafts of the two first motors 3 drive the first roller 4 to reel in the steel cable, so that the steel cable drives the adsorption electromagnetic seat 5 to rise to the initial position, and when the plate needs to be suspended again, the above steps are repeated.

[0036] In this embodiment, the connection relationship between the pulley 6 and the adsorption electromagnetic seat 5 is a fixed connection, but it is limited to embodiment 1. In other subsequent embodiments, the connection relationship between the pulley 6 and the adsorption electromagnetic seat 5 is a sliding connection. Please refer to the specific description in the subsequent embodiments.

[0037] After long-term use, the steel cable of the gantry is very likely to break due to rust, aging and internal wire breakage. At this time, the sling on it is not affected by the upward pulling force, and the sling will carry the metal sheet and fall downward under gravity. At this time, the gravitational potential energy of the sling and the sheet is converted into kinetic energy, and eventually falls to the ground to form a severe impact force. The existing gantry is unable to protect the sling and the metal sheet on it, which causes the sling and the metal sheet to fall to the ground and be damaged by the impact force.

[0038] Example 2: Based on Example 1, Figure 7-Figure 9As shown, a safety component for preventing the plate from falling is also included. The safety component is arranged on the sliding seat 2. The safety component includes two second rollers 301 with mirror-image distribution in the front and back. The two second rollers 301 with mirror-image distribution are both rotatably connected to the lower side of the sliding seat 2. The two second rollers 301 with mirror-image distribution are both fixedly connected to the adsorption electromagnetic seat 5 with a safety cable 302. The safety cable 302 is in a loose state, so that it is in a stress-free state when it is rolled up or released along the second rollers 301. Two first pulleys 303 with mirror-image distribution are rotatably connected to the sliding seat 2. The two first rollers 4 with mirror-image distribution are both fixedly connected to the second pulley 304. Belts are respectively wound between the two first pulleys 303 with mirror-image distribution and the adjacent second pulleys 304, so that when the first roller 4 rolls up the steel cable, it synchronously rolls up the two safety cables 302 through the two first pulleys 303, the two second pulleys 304 and the belt therebetween. A detection component for detecting the breakage of the steel cable is arranged on the adsorption electromagnetic seat 5.

The fixed parts of the elastic telescopic rods 307 distributed in front and back mirror images are respectively fixedly connected to the adjacent detection cylinders 305 and are connected with flexible tubes 308. The flexible tubes 308 are filled with hydraulic oil. The sliding seat 2 is provided with a first connecting component connecting the second roller 301 and the adjacent first pulley 303. When the steel cable breaks, the steel cable releases the pulling force on the two pulleys 6, so that the pulley 6 pushes the hydraulic oil in the adjacent detection cylinder 305 along the adjacent flexible tubes 308 into the fixed parts of the adjacent elastic telescopic rods 307.

[0040] Comparison Figure 7 and Figure 8As shown, the first connecting component includes two first rotating rings 401 with mirror image distribution, and the two first rotating rings 401 with mirror image distribution are respectively sealed and rotatably connected to adjacent first pulleys 303, and the two cooperate to form a closed cavity, which is filled with hydraulic oil. The first pulley 303 is internally sealed and slidably connected with a first limiting shaft 402, and a second elastic element 403 is arranged between the first pulley 303 and the adjacent first limiting shaft 402. The second elastic element 403 is a spring, and the second elastic element 403 is in a compressed state during the suspension. Four first blocking blocks 404 in an annular array are fixedly connected to the second roller 301, and the four first blocking blocks 404 in the annular array are all limitedly matched with the adjacent first limiting shaft 402. When the steel cable breaks, the first limiting shaft 402 is separated from the adjacent first blocking block 404, so that the first pulley 303 cannot drive the adjacent second roller 301 to rotate, and a second connecting component for alleviating the stress of the safety cable 302 is arranged on the sliding seat 2.

[0041] Comparison Fig. 9 and Fig.10 As shown, the buffer assembly includes two buffer rings 501 with mirror-image distribution, and the two buffer rings 501 with mirror-image distribution are both rotatably connected to the lower plane of the sliding seat 2.

The buffer ring 501 cooperates with the adjacent second rotating ring 502 to form a closed cavity, and the closed cavity is filled with hydraulic oil. The internal sealing and sliding connection of the buffer ring 501 is connected to the second limiting shaft 503. A third elastic element 504 is arranged between the buffer ring 501 and the adjacent second limiting shaft 503. The third elastic element 504 is a spring. The third elastic element 504 is used to maintain the state of the second limiting shaft 503. The elastic force of the first elastic element 306 is greater than the elastic force of the adjacent second elastic element 403. The sum of the elastic force of the adjacent elastic telescopic rod 307 and the elastic force of the third elastic element 504 ensures that the resetting of the first elastic element 306 can push the hydraulic oil in the adjacent detection cylinder 305 into the adjacent flexible tube 308. The second roller 301 is fixedly connected with four second positioning blocks 505 in an annular array. The four second positioning blocks 505 in the annular array are all limitedly matched with the adjacent second limiting shaft 503. The hydraulic oil in the closed cavity pushes the second limiting shaft 503 to move and contacts the adjacent second positioning blocks 505, so that the second roller 301 drives the buffer ring 501 to rotate. The first rotating ring 401 is provided with a switching component for switching the docking state of the second roller 301 with the first pulley 303 and the buffer ring 501.

At the same time, the hydraulic oil in the closed cavity formed by the first swivel ring 401 and the adjacent first pulley 303 enters the fixed cylinder 507, so that the first limiting shaft 402 is separated from the adjacent first locking block 404. The sliding seat 2 is provided with two mirror-distributed shock-absorbing components, which are respectively used to reduce the impact force of the adjacent safety cables 302.

[0043] Comparison Figure 8 and Fig.11 As shown, the shock absorbing assembly includes an extrusion block 601, which is fixedly connected to the adjacent buffer ring 501, a buffer cylinder 602 is fixedly connected to the lower side of the sliding seat 2, and a piston shaft 603 is slidably connected inside the buffer cylinder 602. A fourth elastic element 604 is arranged between the buffer cylinder 602 and the adjacent piston shaft 603, and the fourth elastic element 604 is a tension spring. The fourth elastic element 604 is used to provide sliding resistance for the piston shaft 603. The piston shaft 603 is provided with eight oil holes 605 in an annular array. The piston shaft 603 is extruded and matched with the adjacent extrusion block 601. The two rotating rollers 301 rotate through the second limiting shaft 503 and the second positioning block 505 to drive the adjacent buffer ring 501 to rotate, and the buffer ring 501 drives the extrusion block 601 thereon to rotate and extrude the adjacent piston shaft 603. A damping shaft 606 of an annular array is fixedly connected in the buffer cylinder 602. The radius of the damping shaft 606 gradually increases from one end to the other end close to the adjacent buffer ring 501, which is used to reduce the flow aperture of the oil hole 605 and further increase the sliding resistance of the piston shaft 603. The central axis of the damping shaft 606 of the annular array is collinear with the central axis of the adjacent oil hole 605.

[0044] After the gantry is used for a long time, the steel cable is very likely to break due to internal stress and aging when the plate is suspended. Before the steel cable breaks, the output shaft of the first motor 3 drives the second roller 301 to rotate and reel in or release the safety cable 302 through the adjacent first roller 4, the adjacent second pulley 304, the adjacent first pulley 303, the belt therebetween, the first limiting shaft 402 and the first blocking block 404, so that the second roller 301 rotates synchronously with the first roller 4, and the safety cable 302 is reeled and released synchronously with the steel cable, so that the safety cable 302 is in a stress-free state, thereby ensuring the inherent properties of the safety cable 302.

[0045] When the steel cable between the two first rotating rollers 4 breaks, the steel cable is separated from the mirror-distributed pulley 6, and the mirror-distributed pulley 6 is not affected by the steel cable. At this time, the two mirror-distributed first elastic elements 306 drive the adjacent pulley 6 to slide inward along the adsorption electromagnetic seat 5, so that the pulley 6 pushes the hydraulic oil in the adjacent detection cylinder 305 along the flexible tube 308 into the fixed part of the adjacent elastic telescopic rod 307. At this time, the hydraulic oil in the fixed part of the elastic telescopic rod 307 pushes its telescopic end to slide inward, and the extension of the elastic telescopic rod 307 The retracted end extracts the hydraulic oil in the fixed cylinder 507, and the first pulley 303 cooperates with the first rotating ring 401 to form a closed cavity. The hydraulic oil enters the fixed cylinder 507, and at the same time, the elastic force of the second elastic element 403 is released and drives the first limiting shaft 402 to slide along the first pulley 303, and the first limiting shaft 402 is separated from the adjacent first blocking block 404. At this time, the first pulley 303 is separated from the second rotating roller 301, so that the first pulley 303 cannot drive the second rotating roller 301 to rotate and reel in the adjacent safety cable 302.

[0046] When the telescopic end of the elastic telescopic rod 307 slides along the fixed cylinder 507 to extract the hydraulic oil in the closed cavity formed by the first pulley 303 and the first rotating ring 401, the telescopic end of the elastic telescopic rod 307 pushes the hydraulic oil in the fixed cylinder 507 into the connecting pipe 506, and the hydraulic oil enters the closed cavity formed by the buffer ring 501 and the second rotating ring 502 along the connecting pipe 506. At this time, the hydraulic oil in the closed cavity pushes the second limit shaft 503 to slide along the buffer ring 501, and at the same time the third elastic element 504 is compressed. At this time, the adsorption electromagnetic seat 5 and the plate thereon are subjected to weight. The suction electromagnetic seat 5 pulls the two safety cables 302 thereon to move downward synchronously. The safety cables 302 pull the adjacent second roller 301 to rotate. The second roller 301 drives the adjacent buffer ring 501 to rotate synchronously through the second positioning block 505 and the second limiting shaft 503 thereon. The rotation of the buffer ring 501 drives the second limiting shaft 503 thereon to move synchronously and contact with the adjacent second positioning block 505, and limit each other, so that the second roller 301 is locked with the adjacent buffer ring 501 through the limiting of the second limiting shaft 503 and the second positioning block 505.

[0047] When the buffer ring 501 rotates, it drives the extrusion block 601 thereon to rotate synchronously. The extrusion block 601 rotates and contacts the adjacent piston shaft 603. The extrusion block 601 squeezes the adjacent piston shaft 603, causing the piston shaft 603 to slide along the adjacent buffer cylinder 602. At the same time, the fourth elastic element 604 is stretched, and the piston shaft 603 pushes the hydraulic oil in the buffer cylinder 602 to cause the hydraulic oil to flow along the oil holes 605 in the annular array thereon to form resistance. At the same time, as the piston shaft 603 slides, the damping shaft 606 in the annular array gradually enters the corresponding oil holes 605, gradually reducing the flow aperture of the oil holes 605 to form a damping force, so that the two safety cables 302 are gradually stressed, avoiding the gravity of the adsorption electromagnetic seat 5 and the plate thereon directly acting on the two safety cables 302. The cable 302 causes the instantaneous force of the two safety cables 302 to be too large and become damaged, until the damping shaft 606 completely blocks the corresponding oil hole 605. At this time, the extrusion block 601 cannot squeeze the adjacent piston shaft 603, and the piston shaft 603 cannot slide along the adjacent buffer cylinder 602. At this time, the two safety cables 302 cannot drive the adjacent second roller 301 to continue to rotate. At this time, the adsorption electromagnetic seat 5 and the plate thereon cannot continue to fall due to the force of the two safety cables 302. The adsorption electromagnetic seat 5 and the plate thereon are pulled by the two safety cables 302, so that the adsorption electromagnetic seat 5 and the plate thereon cannot continue to fall, and the adsorption electromagnetic seat 5 and the plate thereon are prevented from falling directly to the ground, causing damage to the adsorption electromagnetic seat 5 and the plate thereon.
