Description

Technical Field

[0001] The invention relates to the technical field of barrel-shaped coiled material transportation, in particular to a truss transportation device with a positioning function for barrel-shaped coiled materials. Background Art

[0002] Barrel-shaped coils generally refer to flexible materials that are formed by rolling up to facilitate storage and transportation. Such flexible materials can be further divided into wire materials, film materials, and sheets.

[0003] Compared with smooth surfaces such as film and sheet materials, the rolled wire can be formed through uneven surfaces to improve the axial self-locking performance, so that it can be stacked and transported. However, the truss handling device currently used can only mechanically stack barrel-shaped coils, and after the wire is rolled, the outermost layer of wire is distributed in an uneven state, so the locking performance between the upper and lower layers of the barrel-shaped coil cannot be guaranteed, affecting the transportation stability of the barrel-shaped coil.

[0004] In addition, during the stacking process of barrel-shaped coils, it is impossible to ensure that the center lines between the layers of barrel-shaped coils remain parallel, thereby affecting the stability of the stacking. Summary of the invention

[0005] The object of the present invention is to provide a truss transport device with a positioning function for barrel-shaped coiled materials, so as to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A truss handling device with a positioning function for barrel-shaped coils, the truss handling device is used to place the barrel-shaped coils on a transport vehicle, the barrel-shaped coils are stacked in two layers, the truss handling device includes a truss, a driving device, an adjusting device and a conveyor, a plurality of conveyors are arranged inside the truss, the conveyor is used to escort the barrel-shaped coils, the driving device is connected to the truss, the adjusting device is connected to the driving device, and the adjusting device is used to adjust the placement posture of the barrel-shaped coils.

[0007] The barrel-shaped coils are transported by a truss transport device and placed on a transport vehicle. When placing them, they are double-stacked to improve transportation efficiency. The truss serves as the main installation base for installing and fixing other devices. Multiple conveying tracks are arranged inside the truss, and each conveying track is provided with a conveyor for conveying barrel-shaped coils to facilitate transportation. The driving device serves as the main power unit for conveying barrel-shaped coils. By setting an adjustment device, the barrel-shaped coils are adjusted in posture and automatically positioned, so that the interlocking ability between the two stacked layers of barrel-shaped coils is improved, thereby improving the stability of the stacking.

[0008] Furthermore, the driving device includes a cross arm, a self-propelled component, a lifting component, a transverse module and a clamping claw. The cross arm is tightly connected to the movable end of the transverse module, the fixed end of the transverse module is tightly connected to the truss, a plurality of cross arms are provided along the length direction of the truss, a self-propelled component is provided on the cross arm, the self-propelled component and the lifting component are tightly connected, the self-propelled component drives the lifting component to move along the length direction of the cross arm, and the lifting component is connected to the clamping claw through the adjusting device; The adjusting device includes an angle-changing assembly, which includes an angle-changing motor, a worm, a worm wheel and a fixed seat. The angle-changing motor and the lifting assembly are tightly connected, the output end of the angle-changing motor is transmission-connected to the worm, the end of the worm away from the angle-changing motor is rotatably connected to the lifting assembly, the tooth surfaces of the worm and the worm wheel are meshing, the worm wheel and the fixed seat are tightly connected, and the fixed seat and the clamp are movably connected.

[0009] Crossarms are arranged along the conveying track, for example, in three groups. Each group of crossarms is connected to the truss through a transverse moving module. The transverse moving module adopts a conventional linear drive structure and is fixed on the truss. The movable end is used to drive the crossarm to perform linear displacement. The crossarm is used to slide and guide the lifting assembly, which is driven by the self-propelled assembly. The linear displacement driven by the self-propelled assembly is arranged along the length direction of the crossarm. The lifting assembly is used to generate vertical displacement, so that the transverse moving module, the self-propelled assembly and the lifting assembly generate three-coordinate displacement, which is convenient for driving the clamp to move and place the barrel-shaped coil on the transport vehicle. When the transport vehicle is docked, it cannot be guaranteed that the direction of the entire vehicle is arranged along the length direction of the crossarm, and there will be a certain angle difference. The barrel-shaped coil itself is heavy. When laying the first layer of barrel-shaped coil, an arc-shaped limit groove is set on the truck bed, which can directly fix the first layer of barrel-shaped coil, and the second layer of barrel-shaped coil needs to be placed in the gap between the adjacent first layer of barrel-shaped coil. The first layer of barrel-shaped coil is placed in the limit groove on the truck bed, and it will automatically slide to the lowest point along the wall of the arc-shaped limit groove, so as to perform adaptive positioning. The barrel-shaped coil can be rolled from wire. After rolling, there will be gaps, and when laying the second layer When the barrel-shaped coils are used, the center lines will be offset between the two layers of barrel-shaped coils. Under the action of its own weight, the static friction and clamping force of the second layer of barrel-shaped coil placed on the first layer of barrel-shaped coil are relatively large, and it cannot automatically repair to the center line parallel state. By setting a variable angle component and using a variable angle motor as a power source, the worm is driven to rotate, and the worm cooperates with the worm gear to drive the fixed seat connected to the worm gear to rotate. The fixed seat is used to install the clamping claw, so as to adjust the angle of the clamping claw, so that the center lines of the upper and lower layers of barrel-shaped coils are kept parallel, thereby improving the clamping performance of the lower barrel-shaped coil to the upper barrel-shaped coil, thereby ensuring transportation stability.

[0010] Furthermore, the clamp includes a C-shaped hook and a washer, the C-shaped hook and the fixed seat are movably connected, a plurality of washers are provided on the C-shaped hook, a plurality of inner rings of the washers are rotatably connected to the C-shaped hook, the outer ring of the washer is in contact with the inner ring of the barrel-shaped coil, the adjusting device also includes an induction component, the induction component includes a push rod and an eccentric ring, the eccentric ring is sleeved on the C-shaped hook, the eccentric ring and the C-shaped hook are rotatably connected, a pressure-sensing groove is provided on the eccentric ring, a pressure-bearing spring is provided at the lower end of the push rod, the lower end of the push rod is abutted against the pressure-sensing groove through the pressure-bearing spring, the upper end of the push rod is abutted against the upper wall of the inner ring of the barrel-shaped coil, an angle adjustment coil is provided in the pressure-sensing groove, the lower end of the push rod is inserted into the angle adjustment coil to form an angle adjustment circuit, and the angle variable motor and the angle adjustment circuit are electrically connected.

[0011] The clamping jaws are set up in a split style, with the C-shaped hook as the main load-bearing unit for supporting the gasket. The gasket can rotate on a fixed axis on the C-shaped hook to reduce friction damage during transportation. When transporting the second layer of barrel-shaped coils, the C-shaped hook drives multiple gaskets to be inserted into the inner ring of the barrel-shaped coils, and then the barrel-shaped coils are moved up by the lifting assembly and moved to the transport vehicle. The barrel-shaped coils are placed on the first layer of barrel-shaped coils through three-coordinate adjustment. When the center line of the second layer of barrel-shaped coils is parallel to the center line of the first layer of barrel-shaped coils, the clamping efficiency is optimal, and the push rod compresses the pressure spring under the action of the gravity of the barrel-shaped coils, and the push rod is extended out of the pressure-sensitive groove through the lifting assembly and abuts against the upper wall of the inner ring of the barrel-shaped coils. The worm is driven to rotate by a variable angle motor. The variable angle motor can rotate forward or reverse, and adopts servo control. For example, the maximum rotation angle of the worm wheel in both directions is 15°. When the second layer of barrel-shaped coil is driven to cross the parallel state of the center line, as the spatial angle of the two center lines increases, the second layer of barrel-shaped coil will be driven to deviate upward along the outer sides of the two barrel-shaped coils of the first layer. Since the C-shaped hook rotates with the vertical axis of the ejector rod as the rotation center at this time, the contact point with the gasket is offset during the upward movement of the second layer of barrel-shaped coil. At this time, the ejector rod moves upward under the action of the pressure spring, and the angle adjustment coil cuts the magnetic flux line and generates an induced current. The current generated during the upward movement of the ejector rod is a forward current; when the intersection angle of the two center lines decreases, the second layer of barrel-shaped coil gradually moves to the calibrated position, and moves downward along the outer wall of the first layer of barrel-shaped coil, pushing the ejector rod to move downward. The current generated by the downward movement is a reverse current. When the ejector rod moves to the lowest point, that is, when the reverse current is the largest, the upper and lower layers of barrel-shaped coils enter the parallel state of the center line, thereby automatically positioning.

[0012] Furthermore, the adjustment device also includes a transmission wheel and a driving motor, the driving motor is firmly connected to the C-shaped hook, the output end of the driving motor is drivingly connected to the transmission wheel, the transmission wheel is rotatably connected to the C-shaped hook, and the outer ring of the transmission wheel and the inner ring of the barrel-shaped coil are frictionally driven; The induction component also includes a folding rod, a reset spring and a bias coil. An eccentric groove is provided on the transmission wheel. The folding rod and the eccentric groove are rotatably connected. The folding rod is made of a magnetic material. The reset spring and the bias coil are respectively placed in the eccentric groove. The side of the reset spring away from the wall of the eccentric groove is in contact with the side of the folding rod, and the bent section of the folding rod is inserted into the inner circle of the bias coil.

[0013] The driving motor is fixed on the C-hook and is used to drive the transmission wheel to rotate. The transmission wheel and the inner ring of the barrel-shaped coil are transmitted through friction, so that the transmission wheel can drive the barrel-shaped coil to rotate along its own center line. During the rotation, the gasket is used for auxiliary rotation. The driving motor outputs rated power. At this time, the barrel-shaped coil of the second layer has been placed between the two barrel-shaped coils of the first layer, and the barrel-shaped coil is wound in disorder. The contact area between the two layers of barrel-shaped coils is related to the contact point of the outer ring of the second layer of barrel-shaped coil. The driving motor drives the barrel-shaped coil of the second layer to rotate through the transmission wheel. The folding rod in the eccentric groove of the transmission wheel rotates under the action of centrifugal force and stretches the reset spring. When the folding rod rotates into the bias coil, since the folding rod is made of magnet material, the bias coil is generated. An induced current is generated. When the output power of the driving motor is constant, when the second layer of barrel-shaped coil rotates, it is affected by the contact area between the two barrel-shaped coils of the first layer, that is, the contact friction. The larger the contact area, the greater the friction resistance, the lower the speed of the transmission wheel, and the centrifugal force on the folding rod is reduced. The folding rod rotates in the direction away from the bias coil under the action of the reset spring. Since the direction of the current generated on the bias coil is related to the rotation direction of the folding rod, when the second layer of barrel-shaped coil is driven by the transmission wheel to rotate one circle, the lowest speed is confirmed, and the second layer of barrel-shaped coil is adjusted to the corresponding position through the transmission wheel. At this time, the area of ​​mutual engagement between the upper and lower layers of barrel-shaped coils is the largest, so that the axial limit of the first layer of barrel-shaped coil on the second layer of barrel-shaped coil is the largest, thereby improving the safety of subsequent transportation.

[0014] Furthermore, there are two transmission wheels, which are respectively located on both sides of the eccentric ring; When stacked: The circuits where the drive motor and bias coil are located are electrically connected.

[0015] By setting two transmission wheels, the torque output stability is improved, so that the two transmission wheels drive the barrel-shaped coil to rotate through two points respectively. According to the current fluctuation on the bias coil, the lowest rotation speed of the second layer of barrel-shaped coil is confirmed, and the driving motor is used for adjustment to maximize the engagement performance between the upper and lower layers.

[0016] Furthermore, the self-propelled component includes a self-propelled motor and a self-propelled rack. The self-propelled motor and the lifting component are tightly connected. A self-propelled gear is provided at the output end of the self-propelled motor. The self-propelled rack and the cross arm are tightly connected. The tooth surfaces of the self-propelled gear and the self-propelled rack are meshed, and the lifting component and the cross arm are slidably connected.

[0017] The self-propelled motor is fixed on the lifting assembly and is used to output torque to drive the self-propelled gear to rotate. The self-propelled gear engages with the self-propelled rack on the cross arm, thereby driving the lifting assembly to move along the length direction of the cross arm, making it easy to move the barrel-shaped coiled materials on the conveyor to the transport vehicle, and the lifting assembly is slidably guided by the cross arm.

[0018] Furthermore, the lifting assembly includes a lifting frame, a lifting motor and a wire drum, the lifting frame includes a fixed frame and a movable frame, the fixed frame and the cross arm are slidably connected, the fixed frame and the self-propelled motor are tightly connected, the lifting motor and the fixed frame are tightly connected, the output end of the lifting motor and the wire drum are tightly connected, the wire drum and the fixed frame are rotatably connected, a twisted rope is wound around the wire drum, the lower end of the twisted rope is tightly connected to the movable frame, the movable frame and the fixed frame are slidably connected, the lower end of the movable frame is tightly connected to the variable angle motor, and the worm gear and the movable frame are rotatably connected.

[0019] The lifting frame serves as the installation base of the lifting assembly and fixes the self-propelled motor at the same time, so that it can move along the length direction of the crossarm during the driving process. The lifting motor is fixed on it, and the lifting motor is used to drive the wire drum to rotate, and the wire drum is used to reel in and out the twisted rope. During the process of reeling in and out of the twisted rope, the movable frame is driven to move up and down, and the movable frame is slidably guided by the fixed frame, so as to facilitate the vertical displacement adjustment of the barrel-shaped coiled material. The movable frame is used to rotate and guide the worm gear to facilitate angle adjustment.

[0020] Furthermore, the adjusting device also includes a distance adjusting component, the fixed seat is connected to the clamping claw through the distance adjusting component, the distance adjusting component includes a front mounting seat, a rear mounting seat, a distance adjusting motor and a transmission chain, the distance adjusting motor and the fixed seat are tightly connected, the output end of the distance adjusting motor is transmission-connected to the transmission chains on both sides, a sprocket is arranged on the inner ring of the transmission chain, the transmission chain is movably connected to the fixed seat through the sprocket, the front mounting seat and the rear mounting seat are tightly connected to the transmission chain respectively, the lower ends of the front mounting seat and the rear mounting seat are tightly connected to the C-shaped hooks respectively, and the front mounting seat, the rear mounting seat and the fixed seat are slidingly connected.

[0021] Two C-shaped hooks are arranged on each fixed seat, and the two C-shaped hooks are fixed respectively by a transmission chain. Two sprockets are arranged on the inner ring of the transmission chain and are driven by a pitch-adjusting motor. When the transmission chain moves, it drives the front mounting seat and the rear mounting seat respectively. The front mounting seat is located in front of the conveying direction of the barrel-shaped coil. When the front mounting seat and the rear mounting seat move, they can drive the C-shaped hooks connected to them to move.

[0022] As an optimization, a chain-through groove is provided on the front mounting seat, and the lower side of the transmission chain passes through the chain-through groove. The front mounting seat is tightly connected to the upper layer of the transmission chain, and the rear mounting seat is tightly connected to the lower layer of the transmission chain. Due to the different specifications of the coils, during the double-roll handling process, the front mounting seat is fixed to the upper layer of the transmission chain, and the rear mounting seat is fixed to the lower layer of the transmission chain, and keeps sliding with the fixed seat. During the transmission process of the transmission chain, since the chain-through groove of the front mounting seat does not contact the transmission chain, as the transmission chain rotates, it can drive the distance between the C-shaped hooks to expand or decrease, which is convenient for conveying barrel-shaped coils of different specifications and prevents interference.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the first layer of barrel-shaped coiled materials is placed in the limiting groove on the bucket, and will automatically slide down to the lowest point along the arc-shaped limiting groove wall, thereby performing adaptive positioning; a variable angle motor is used as a power source to drive the worm to rotate, and the worm cooperates with the worm wheel to drive the fixed seat connected to the worm wheel to rotate, and the fixed seat is used to install the clamping claw, so as to adjust the angle of the clamping claw, so that the center lines of the upper and lower layers of barrel-shaped coiled materials are kept parallel, thereby improving the clamping of the lower layer of barrel-shaped coiled materials to the upper layer of barrel-shaped coiled materials. The clamping performance ensures the transportation stability. When the second layer of barrel-shaped coil is driven to cross the parallel state of the center line, as the spatial angle between the two center lines increases, the second layer of barrel-shaped coil will be driven to deviate upward along the outer sides of the two barrel-shaped coils of the first layer. Since the C-shaped hook rotates with the vertical axis of the ejector rod as the rotation center, the contact point with the gasket will deviate during the upward movement of the second layer of barrel-shaped coil. At this time, the ejector rod moves upward under the action of the pressure spring, and the angle adjustment coil cuts the magnetic flux line and generates an induced current. The current generated is a positive current; when the intersection angle of the two center lines decreases, the second layer of barrel-shaped coiled material gradually moves to the marked position, and moves downward along the outer wall of the first layer of barrel-shaped coiled material, pushing the top rod to move downward. The current generated by the downward movement is a reverse current. When the top rod moves to the lowest point, that is, when the reverse current is the largest, the upper and lower layers of barrel-shaped coiled materials enter a state of parallel center lines, thereby automatically positioning; when the output power of the drive motor is constant, when the second layer of barrel-shaped coiled material rotates, it is affected by the contact area between the two barrel-shaped coils of the first layer, that is, the contact friction force. The larger the contact area, the greater the friction resistance, the lower the speed of the transmission wheel, and the centrifugal force on the folding rod is reduced. The folding rod rotates in the direction away from the bias coil under the action of the reset spring. When the second layer of barrel-shaped coiled material is driven by the transmission wheel to rotate one circle, the lowest speed is confirmed, and the second layer of barrel-shaped coiled material is adjusted to the corresponding position through the transmission wheel. At this time, the area of ​​mutual engagement between the upper and lower layers of barrel-shaped coiled materials is the largest, so that the axial limit of the first layer of barrel-shaped coiled material on the second layer of barrel-shaped coiled material is the largest, thereby improving the safety of subsequent transportation.

[0030] Further, the driving device 2 includes a cross arm 21, a self-propelled component 22, a lifting component 23, a transverse module 24 and a clamp 25. The cross arm 21 is tightly connected to the movable end of the transverse module 24, and the fixed end of the transverse module 24 is tightly connected to the truss 1. The cross arm 21 is provided with a plurality of self-propelled components 22 along the length direction of the truss 1. The cross arm 21 is provided with a self-propelled component 22. The self-propelled component 22 and the lifting component 23 are tightly connected. The self-propelled component 22 drives the lifting component 23 to move along the length direction of the cross arm 21. The lifting component 23 is connected to the clamp 25 through the adjusting device 3. The adjusting device 3 includes an angle-changing assembly 33, which includes an angle-changing motor 331, a worm 332, a worm wheel 333 and a fixed seat 334.

[0031] The crossarms 21 are arranged along the conveying track, for example, in three groups. Each group of crossarms 21 is connected to the truss 1 through a transverse module 24. The transverse module 24 adopts a conventional linear drive structure and is fixed on the truss 1. The movable end is used to drive the crossarms 21 to perform linear displacement. The crossarms 21 are used to slide and guide the lifting assembly 23, which is driven by the self-propelled assembly 22. The linear displacement driven by the self-propelled assembly 22 is arranged along the length direction of the crossarms 21. The lifting assembly 23 is used to generate vertical displacement, so that the transverse module 24, the self-propelled assembly 22 and the lifting assembly 23 generate three-coordinate displacement, which is convenient for driving the clamping claw 25 to move and place the barrel-shaped coil 5 on the transport vehicle 6. When the transport vehicle 6 is docked, it is impossible to ensure that the direction of the entire vehicle is arranged along the length direction of the crossarm, and there will be a certain angle difference. The barrel-shaped coil 5 itself is heavy. When the first layer of barrel-shaped coil 5 is laid, an arc-shaped limit groove is set on the truck bed, which can directly fix the first layer of barrel-shaped coil 5, and the second layer of barrel-shaped coil 5 needs to be placed in the gap between the adjacent first layer of barrel-shaped coil 5. The first layer of barrel-shaped coil 5 is placed in the limit groove on the truck bed, and it will automatically slide to the lowest point along the wall of the arc-shaped limit groove, so as to perform adaptive positioning. The barrel-shaped coil 5 can be made of wire rod. After rolling, there will be a gap. When the second layer of barrel-shaped coil 5 is laid, the two layers of barrel-shaped coils 5 will produce a center line offset. Under the action of its own weight, the static friction force and the clamping force of the second layer of barrel-shaped coil 5 placed on the first layer of barrel-shaped coil 5 are relatively large, and it is impossible to automatically repair to a center line parallel state. By setting an angle-changing component 33 and adopting an angle-changing motor 331 as a power source, the worm 332 is driven to rotate. The worm 332 cooperates with the worm gear 333 to drive the fixed seat 334 connected to the worm gear 333 to rotate. The fixed seat 334 is used to install the clamping claw 25, so as to adjust the angle of the clamping claw 25, so that the center lines of the upper and lower layers of barrel-shaped coil 5 are kept parallel, and the clamping performance of the lower layer of barrel-shaped coil 5 on the upper layer of barrel-shaped coil 5 is improved, thereby ensuring transportation stability.

[0032] Furthermore, the clamping jaw 25 includes a C-shaped hook 251 and a washer 252, the C-shaped hook 251 is movably connected to the fixing seat 334, a plurality of washers 252 are provided on the C-shaped hook 251, the inner rings of the plurality of washers 252 are rotatably connected to the C-shaped hook 251, the outer rings of the washers 252 are in contact with the inner ring of the barrel-shaped coil 5, the adjusting device 3 also includes a sensing component 32, the sensing component 32 includes a push rod 321 and an eccentric ring 324, the eccentric ring 324 is sleeved on the C-shaped hook 251, and the eccentric ring 324 is sleeved on the C-shaped hook 251. The ring 324 is rotatably connected with the C-shaped hook 251, a pressure-sensing groove 3241 is provided on the eccentric ring 324, a pressure-bearing spring 322 is provided at the lower end of the push rod 321, the lower end of the push rod 321 abuts against the pressure-sensing groove 3241 through the pressure-bearing spring 322, the upper end of the push rod 321 abuts against the upper wall of the inner circle of the barrel-shaped coil 5, an angle adjustment coil 323 is provided in the pressure-sensing groove 3241, the lower end of the push rod 321 is inserted into the angle adjustment coil 323 to form an angle adjustment circuit, and the angle variable motor 331 is electrically connected to the angle adjustment circuit.

[0033] The clamping claw 25 is set up in a split manner, and the C-shaped hook 251 is used as the main load-bearing unit to support the gasket 252. The gasket 252 can rotate on the C-shaped hook 251 to reduce friction damage during transportation. When the second layer of barrel-shaped coil 5 is transported, the C-shaped hook 251 drives multiple gaskets 252 to be inserted into the inner ring of the barrel-shaped coil 5, and then the barrel-shaped coil 5 is mobilized to move up through the lifting component 23 and moved to the transport vehicle 6. Through three-coordinate adjustment, the barrel-shaped coil 5 is placed on the first layer of barrel-shaped coil 5. When the center line of the second layer of barrel-shaped coil 5 is parallel to the center line of the first layer of barrel-shaped coil 5, the clamping efficiency is optimal, and the push rod 321 compresses the pressure spring 322 under the action of the gravity of the barrel-shaped coil 5, and the push rod 321 is extended out of the pressure-sensing groove 3241 through the lifting component 23, and abuts against the upper wall of the inner ring of the barrel-shaped coil 5.

For example, the maximum rotation angle of the worm wheel 333 in both directions is 15°. When the second layer of barrel-shaped coil 5 is driven to cross the parallel state of the center line, as the spatial angle of the two center lines increases, the second layer of barrel-shaped coil 5 will be driven to deviate upward along the outer sides of the two barrel-shaped coils 5 of the first layer. At this time, the C-shaped hook 251 rotates with the vertical axis of the top rod 321 as the rotation center. During the upward movement of the second layer of barrel-shaped coil 5, the contact point with the gasket 252 is generated. When the angle between the two center lines decreases, the second layer of barrel-shaped coil 5 gradually shifts to the marked position and moves downward along the outer wall of the first layer of barrel-shaped coil 5, pushing the top rod 321 to move downward. The current generated by the downward movement is a reverse current. When the top rod 321 moves to the lowest point, that is, when the reverse current is the largest, the upper and lower layers of barrel-shaped coil 5 enter a state of parallel center lines, thereby performing automatic positioning.

[0034] Furthermore, the adjusting device 3 further comprises a transmission wheel 31 and a driving motor 35, the driving motor 35 is fastened to the C-shaped hook 251, the output end of the driving motor 35 is transmission-connected to the transmission wheel 31, the transmission wheel 31 is rotationally connected to the C-shaped hook 251, and the outer ring of the transmission wheel 31 and the inner ring of the barrel-shaped coil 5 are frictionally driven; The induction component 32 also includes a folding rod 325, a reset spring 326 and a bias coil 327. An eccentric groove is provided on the transmission wheel 31. The folding rod 325 and the eccentric groove are rotatably connected. The folding rod 325 is made of a magnetic material. The reset spring 326 and the bias coil 327 are respectively placed in the eccentric groove. The side of the reset spring 326 away from the wall of the eccentric groove is in contact with the side of the folding rod 325, and the bent section of the folding rod 325 is inserted into the inner circle of the bias coil 327.

[0035] The driving motor 35 is fixed on the C-shaped hook 251, and is used to drive the transmission wheel 31 to rotate. The transmission wheel 31 and the inner ring of the barrel-shaped coil 5 are transmitted through friction, so that the transmission wheel 31 can drive the barrel-shaped coil 5 to rotate along its own center line. During the rotation, the gasket 252 is used for auxiliary rotation. The driving motor 35 outputs rated power. Since the barrel-shaped coil 5 of the second layer has been placed between the two barrel-shaped coils 5 of the first layer at this time, and the barrel-shaped coil 5 is wound in a disorderly manner, the contact area between the two layers of barrel-shaped coils 5 is related to the contact point of the outer ring of the second layer of barrel-shaped coil 5, the driving motor 35 drives the barrel-shaped coil 5 of the second layer to rotate through the transmission wheel 31, and the folding rod 325 in the eccentric groove of the transmission wheel 31 rotates under the action of centrifugal force and stretches the reset spring 326. When the folding rod 325 rotates into the bias coil 327, since the folding rod 325 is made of magnet material, the bias An induced current is generated on the coil 327. When the output power of the driving motor 35 is constant, when the second layer of barrel-shaped coil 5 rotates, it is affected by the contact area between the two barrel-shaped coils 5 of the first layer, that is, the contact friction. The larger the contact area, the greater the friction resistance, the speed of the transmission wheel 31 is reduced, and the centrifugal force on the folding rod 325 is reduced. Under the action of the reset spring 326, the folding rod 325 rotates in the direction away from the bias coil 327. Since the direction of the current generated on the bias coil 327 is related to the rotation direction of the folding rod 325, when the second layer of barrel-shaped coil 5 is driven to rotate one circle by the transmission wheel 31, the lowest speed is confirmed, and the second layer of barrel-shaped coil 5 is adjusted to the corresponding position by the transmission wheel 31. At this time, the area of ​​mutual engagement between the upper and lower layers of barrel-shaped coils 5 is the largest, so that the axial limitation of the first layer of barrel-shaped coil 5 on the second layer of barrel-shaped coil 5 is maximized, thereby improving the safety of subsequent transportation.

[0036] Furthermore, two transmission wheels 31 are provided, and the two transmission wheels 31 are respectively located on both sides of the eccentric ring 324; When stacked: the circuit where the drive motor 35 and the bias coil 327 are located is electrically connected.

[0037] By setting two transmission wheels 31, the torque output stability is improved, so that the two transmission wheels 31 drive the barrel-shaped coil 5 to rotate through two points respectively, and the lowest rotation speed of the second layer of barrel-shaped coil 5 is confirmed according to the current fluctuation on the bias coil 327, so that the driving motor 35 is used for adjustment to maximize the engagement performance between the upper and lower layers.

[0038] Furthermore, the self-propelled component 22 includes a self-propelled motor 221 and a self-propelled rack 223. The self-propelled motor 221 and the lifting component 23 are tightly connected. A self-propelled gear 222 is provided at the output end of the self-propelled motor 221. The self-propelled rack 223 and the cross arm 21 are tightly connected. The tooth surfaces of the self-propelled gear 222 and the self-propelled rack 223 are meshed, and the lifting component 23 and the cross arm 21 are slidably connected.

[0039] The self-propelled motor 221 is fixed on the lifting assembly 23, and is used to output torque to drive the self-propelled gear 222 to rotate. The self-propelled gear 222 engages with the self-propelled rack 223 on the cross arm 21, thereby driving the lifting assembly 23 to move along the length direction of the cross arm 21, so as to facilitate the transportation of the barrel-shaped coil 5 on the conveyor 4 to the transport vehicle 6, and the lifting assembly 23 is slidably guided by the cross arm 21.

[0040] Furthermore, the lifting assembly 23 includes a lifting frame 231, a lifting motor 232 and a wire drum 233. The lifting frame 231 includes a fixed frame 2311 and a movable frame 2312. The fixed frame 2311 is slidably connected to the cross arm 21, the fixed frame 2311 is firmly connected to the self-propelled motor 221, the lifting motor 232 is firmly connected to the fixed frame 2311, the output end of the lifting motor 232 is firmly connected to the wire drum 233, the wire drum 233 is rotatably connected to the fixed frame 2311, a twisted rope 234 is wound around the wire drum 233, the lower end of the twisted rope 234 is firmly connected to the movable frame 2312, the movable frame 2312 is slidably connected to the fixed frame 2311, the lower end of the movable frame 2312 is firmly connected to the variable angle motor 331, and the worm gear 333 is rotatably connected to the movable frame 2312.

[0041] The lifting frame 231 serves as the installation base of the lifting assembly 23, and at the same time fixes the self-propelled motor 221 to facilitate its movement along the length direction of the cross arm 21 during the driving process. The lifting motor 232 is fixed thereon, and the lifting motor 232 is used to drive the wire drum 233 to rotate, and the wire drum 233 is used to reel in and out the twisted rope 234. During the reeling and unreeling process of the twisted rope 234, the movable frame 2312 is driven to move up and down, and the movable frame 2312 is slidably guided by the fixed frame 2311, so as to facilitate the vertical displacement adjustment of the barrel-shaped coil 5. The movable frame 2312 is used to rotate and guide the worm gear 333 to facilitate angle adjustment.

[0042] Furthermore, the adjusting device 3 also includes a distance adjusting component 34, and the fixed seat 334 is connected to the clamping claw 25 through the distance adjusting component 34. The distance adjusting component 34 includes a front mounting seat 341, a rear mounting seat 342, a distance adjusting motor 343 and a transmission chain 344. The distance adjusting motor 343 and the fixed seat 334 are fastened together, and the output end of the distance adjusting motor 343 is transmission-connected to the transmission chains 344 on both sides. A sprocket is arranged on the inner ring of the transmission chain 344, and the transmission chain 344 is movably connected to the fixed seat 334 through the sprocket. The front mounting seat 341 and the rear mounting seat 342 are fastened together with the transmission chain 344 respectively, and the lower ends of the front mounting seat 341 and the rear mounting seat 342 are fastened together with the C-shaped hook 251 respectively, and the front mounting seat 341, the rear mounting seat 342 and the fixed seat 334 are slidingly connected.

[0043] Two C-shaped hooks 251 are arranged on each fixed seat 334, and the two C-shaped hooks 251 are fixed respectively by a transmission chain 344. Two sprockets are arranged on the inner ring of the transmission chain 344, and are driven by a pitch-adjusting motor 343. When the transmission chain 344 moves, it drives the front mounting seat 341 and the rear mounting seat 342 respectively. The front mounting seat 341 is located in front of the conveying direction of the barrel-shaped coil 5. When the front mounting seat 341 and the rear mounting seat 342 move, they can drive the C-shaped hooks 251 connected to them to move.

[0044] As an optimization, a chain-through groove is provided on the front mounting seat 341, and the lower side of the transmission chain 344 passes through the chain-through groove. The front mounting seat 341 is tightly connected to the upper layer of the transmission chain 344, and the rear mounting seat 342 is tightly connected to the lower layer of the transmission chain 344. Due to the different specifications of the coils, during the double-roll transportation process, the front mounting seat 341 is fixed to the upper layer of the transmission chain 344, and the rear mounting seat 342 is fixed to the lower layer of the transmission chain, and keeps sliding with the fixed seat 334. During the transmission process of the transmission chain 344, since the chain-through groove of the front mounting seat 341 does not contact the transmission chain 344, as the transmission chain 344 rotates, it can drive to expand or reduce the distance between the C-shaped hooks 251, so as to facilitate the transportation of barrel-shaped coils 5 of different specifications and prevent interference.

[0045] The working principle of the present invention is as follows: the first layer of barrel-shaped coiled material 5 is placed in the limiting groove on the truck bed, and will automatically slide down to the lowest point along the arc-shaped limiting groove wall, thereby performing adaptive positioning; a variable angle motor 331 is used as a power source to drive the worm 332 to rotate, and the worm 332 cooperates with the worm gear 333 to drive the fixed seat 334 connected to the worm gear 333 to rotate, and the fixed seat 334 is used to install the clamping claw 25, so as to adjust the angle of the clamping claw 25, so that the center lines of the upper and lower layers of barrel-shaped coiled material 5 are kept parallel, thereby improving the clamping claw 334 of the lower layer on the barrel-shaped coiled material 5 of the upper layer. The clamping performance ensures the transportation stability; when the second layer of barrel-shaped coil 5 is driven to cross the parallel state of the center line, as the spatial angle between the two center lines increases, the second layer of barrel-shaped coil 5 will be driven to deviate upward along the outer sides of the two barrel-shaped coils 5 of the first layer. At this time, the C-shaped hook 251 rotates with the vertical axis of the push rod 321 as the rotation center. During the upward movement of the second layer of barrel-shaped coil 5, the contact point with the gasket 252 is offset. At this time, the push rod 321 moves upward under the action of the pressure spring 322, and the angle adjustment coil 323 moves to cut the magnetic flux lines and generates an induced current. The push rod 32 The current generated during the upward movement is a positive current; when the intersection angle of the two center lines decreases, the second layer of barrel-shaped coiled material 5 gradually moves to the marked position and moves downward along the outer wall of the first layer of barrel-shaped coiled material 5, pushing the top rod 321 to move downward. The current generated by the downward movement is a reverse current. When the top rod 321 moves to the lowest point, that is, when the reverse current is the largest, the upper and lower layers of barrel-shaped coiled materials 5 enter a state of parallel center lines, thereby automatically positioning. When the output power of the driving motor 35 is constant, when the second layer of barrel-shaped coiled material 5 rotates, it is affected by the contact area between the two barrel-shaped coiled materials 5 of the first layer. The larger the contact area, the greater the friction resistance, the lower the rotation speed of the transmission wheel 31, and the centrifugal force on the folding rod 325 is reduced. The folding rod 325 rotates in the direction away from the bias coil 327 under the action of the return spring 326. When the second layer of the barrel-shaped coil 5 is driven by the transmission wheel 31 to rotate one circle, the lowest rotation speed is confirmed, and the second layer of the barrel-shaped coil 5 is adjusted to the corresponding position through the transmission wheel 31. At this time, the area of ​​mutual engagement between the upper and lower layers of the barrel-shaped coil 5 is the largest, so that the axial limitation of the first layer of the barrel-shaped coil 5 on the second layer of the barrel-shaped coil 5 is maximized, thereby improving the safety of subsequent transportation.
