Description

Technical Field

[0001] This invention belongs to the field of hoisting technology, and in particular relates to an automatic tilting system for aerial transport. Background Technology

[0002] After the workpiece is processed, it is placed horizontally. When painting the workpiece, it needs to be placed at an angle to facilitate shot blasting and shot cleaning. The horizontally placed workpiece is lifted by a painting hoist. After the workpiece is lifted to a high place, the workpiece is tilted by an automatic tilting mechanism to meet the painting requirements and achieve the goal of saving costs.

[0003] Currently, after structural welding, the workpieces are sent horizontally to the painting line. After manual hanging, due to the different lengths of the lifting tools used to lift the workpieces, during the lifting process, a shorter lifting tool is needed to lift the workpiece first, and then a longer lifting tool lifts the other end of the workpiece. When the shorter lifting tool tilts the workpiece upwards, the workpiece is prone to deflection and squeezing, which in turn causes a large impact on the tooling and carriers stored below, seriously affecting the work safety of the personnel at the bottom. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies of the prior art, the present invention provides an automatic tilting system for aerial conveying, which aims to solve the technical problem of safety hazards caused by the impact on the workpiece tooling below the hoisted workpiece due to the tilting of the workpiece during the lifting process.

[0007] In this embodiment of the invention, the lifting device is provided with a first fixed seat for a fixed extended section. The locking device includes a locking seat, a movable seat, and a deflection block. The locking seat is disposed on the lifting device and located on the side of the first fixed seat away from the fixed sling. The deflection block is rotatably disposed on the movable seat and locked on the locking seat. The lifting section passes through the movable seat and extends to the side of the movable seat away from the first fixed seat. The unlocking device includes a movable module and a drive mechanism disposed on the movable module. The drive mechanism is used to abut against the deflection block to drive the deflection block to deflect away from the locking seat. The movable module is used to drive the movable seat to move toward the first fixed seat.

[0008] In this embodiment of the invention, the locking seat is a rack seat, and a plurality of rack grooves are spaced apart on the rack seat. The deflection block forms a rack body that abuts against the bottom of the rack groove. The driving mechanism includes a first telescopic driving member disposed on the moving module and a pressure plate connected to the first telescopic driving member. The first telescopic driving member is used to drive the pressure plate to press down the deflection block to deflect it, so that the rack body is misaligned with the bottom of the rack groove.

[0009] In this embodiment of the invention, the locking device further includes a slide bar seat disposed on the lifting device. The slide bar seat is located below the locking seat, and the movable seat has a sliding hole for the slide bar seat to pass through.

[0010] In this embodiment of the invention, the moving module includes a first translation mechanism and a clamping block disposed on the first translation mechanism. A driving mechanism is disposed on the clamping block. Clamping openings for inserting the clamping block are provided on both sides of the moving seat. The first translation mechanism is used to drive the clamping block to push the moving seat to move on the slide block.

[0011] In this embodiment of the invention, a fixed pulley is provided on the first fixed seat, the extended section is connected to the lifting device and extends to the movable seat by passing around the lower side of the fixed pulley, and a movable pulley is provided on the movable seat, the lifting section passes around the upper side of the movable pulley and extends to the side of the movable seat away from the first fixed seat.

[0012] In this embodiment of the invention, the extended section is a rotating rod, the locking device is a locking pin, and the lifting device is provided with a second fixed seat and a third fixed seat at intervals on one side of the fixed sling. One end of the rotating rod is rotatably mounted on the second fixed seat, and the other end of the rotating rod is detachably mounted on the third fixed seat through the locking pin. The unlocking device includes a second telescopic drive member and a plug-in gripper provided on the second telescopic drive member. The second telescopic drive member is used to drive the plug-in gripper to grab the locking pin and pull it out from the third fixed seat.

[0013] In this embodiment of the invention, the locking pin is made of ferromagnetic metal, and the insertion / removal gripper is an electromagnet.

[0014] In this embodiment of the invention, the unlocking device further includes a sliding mechanism, a swing mechanism movably disposed on the sliding mechanism, and a support rod disposed on the swing mechanism. A second telescopic drive member is disposed on the sliding mechanism. The sliding mechanism is used to drive the second telescopic drive member and the swing mechanism to approach or move away from the rotating rod. The swing mechanism is used to drive the support rod to abut against the rotating rod and support the downward swinging motion of the rotating rod.

[0015] Through the above technical solution, the automatic tilting system for aerial transport provided by the embodiments of the present invention has the following beneficial effects:

[0016] When using the above-mentioned automatic tilting system for aerial conveying, the aerial conveying equipment includes a lifting device, a fixed sling, and a movable sling. The fixed and movable slings are mounted on the lifting device, which can move in the air to lift and transport the workpiece. The locking device on the lifting device can lock the lifting height of the movable sling, ensuring that the lifting height of the movable sling is equal to that of the fixed sling in the initial state, thus achieving stable lifting of the workpiece. Simultaneously, the lifting device of the aerial conveying equipment can transport the lifted workpiece and the locking device to the unlocking device side, allowing the locking and unlocking devices to connect. The unlocking device can then release the locking device from locking the movable sling, extending the vertical lifting length of the movable sling and lowering its lifting height. The end of the lifted workpiece connected to the movable sling tilts downwards, achieving workpiece tilting. During the tilting process, the workpiece remains away from and does not contact the workpiece fixture placed below, preventing impact on the workpiece fixture when tilting and improving operational safety.

[0047] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0048] After the workpiece is processed, it is placed horizontally. When painting the workpiece, it needs to be placed at an angle to facilitate shot blasting and shot cleaning. The horizontally placed workpiece is lifted by a painting hoist. After the workpiece is lifted to a high place, the workpiece is tilted by an automatic tilting mechanism to meet the painting requirements and achieve the goal of saving costs.

[0049] Currently, after structural welding, the workpieces are sent horizontally to the painting line. After manual hanging, due to the different lengths of the lifting tools used to lift the workpieces, during the lifting process, a shorter lifting tool is needed to lift the workpiece first, and then a longer lifting tool lifts the other end of the workpiece. When the shorter lifting tool tilts the workpiece upwards, the workpiece is prone to deflection and squeezing, which in turn causes a large impact on the tooling and carriers stored below, seriously affecting the work safety of the personnel at the bottom.

[0050] Based on this, the present application provides an automatic tilting system for aerial conveying, which aims to solve the technical problem that the tilting and rotation of the workpiece during the lifting process causes an impact on the carrier on which the workpiece is placed, resulting in safety hazards.

[0051] The automatic tilting system for aerial transport according to the present invention is described below with reference to the accompanying drawings.

[0052] like Figures 1 to 3 As shown, in an embodiment of the present invention, an automatic tilting system for aerial transport is provided, wherein the automatic tilting system for aerial transport includes:

[0053] The aerial transport equipment 1 includes a lifting device 11, a fixed sling 12 and a movable sling 13. The fixed sling 12 and the movable sling 13 are spaced apart on the lifting device 11, and the lifting device 11 can move in the air.

[0054] Locking device 2 is installed on lifting device 11 and is used to lock the lifting height of movable sling 13 so that the lifting height of movable sling 13 is equal to the lifting height of fixed sling 12.

[0055] Unlocking device 3 is used to dock with locking device 2 and drive locking device 2 to adjust the hoisting height of movable sling 13 so that the hoisting height of movable sling 13 is lower than the hoisting height of fixed sling 12.

[0056] When using the above-mentioned automatic tilting system for aerial transport, the aerial transport device 1 includes an aerial transport equipment 1, a locking device 2, and an unlocking device 3. The aerial transport equipment 1 includes a lifting device 11, a fixed sling 12, and a movable sling 13. The fixed sling 12 and the movable sling 13 are mounted on the lifting device 11, which can move in the air to lift and transport the workpiece 6. The locking device 2 mounted on the lifting device 11 can lock the lifting height position of the movable sling 13, so that the lifting height of the movable sling 13 is equal to that of the fixed sling 12 in the initial state, and the workpiece 6 can be stably lifted. At the same time, the aerial transport equipment 1... The lifting device 11 can transport the lifted workpiece 6 and the locking device 2 to the side of the unlocking device 3, so that the locking device 2 and the unlocking device 3 can be connected. The locking device 2 can be released from the lock on the movable sling 13 through the unlocking device 3, so that the vertical lifting length of the movable sling 13 is extended and the lifting height of the movable sling 13 is reduced. The end of the lifted workpiece 6 connected to the movable sling 13 tilts downward, so that the workpiece 6 tilts. During the tilting process, the workpiece 6 is always far away from the workpiece fixture placed below and does not come into contact with it. This can avoid the workpiece 6 from impacting the workpiece fixture below when it tilts, and improve the safety of the work order.

[0057] See Figure 1 and Figure 2 In this embodiment of the invention, the movable sling 13 includes an extended section 131 connected to the lifting device 11 and a lifting section 132 connected to the extended section 131. The locking device 2 is used to lock the position of the extended section 131 so that the lifting height of the lifting section 132 is equal to the lifting height of the fixed sling 12. By setting the movable sling 13 as an extended section 131 and a lifting section 132, and using the locking device 2 to lock the position of the extended section 131, the extended section 131 is used to extend the length of the movable sling 13 when it is necessary to tilt the workpiece 6, while the lifting section 132 hangs freely, serving to lift the workpiece 6. Specifically, when the hoisting height of the movable sling 13 is equal to the hoisting height of the fixed sling 12, the extension direction of the extended section 131 can be set laterally, that is, the entire length of the extended section 131 is at the same horizontal position, and the hoisting section 132 hangs freely. After the unlocking device 3 releases the lock on the locking device 2, the end of the extended section 131 connected to the hoisting section 132 can swing downward, thereby changing the hoisting height of the entire movable sling 13.

[0058] See also Figures 1 to 3In the first embodiment of the present invention, the lifting device 11 is provided with a first fixed seat 21 for fixing the extended section 131. The locking device 2 includes a locking seat 22, a movable seat 24 and a deflection block 26. The locking seat 22 is provided on the lifting device 11 and located on the side of the first fixed seat 21 away from the fixed sling 12. The deflection block 26 is rotatably provided on the movable seat 24 and is locked on the locking seat 22. The lifting section 132 passes through the movable seat 24 and extends to the side of the movable seat 24 away from the first fixed seat 21. The unlocking device 3 includes a movable module 31 and a driving mechanism 32 provided on the movable module 31. The driving mechanism 32 is used to abut against the deflection block 26 to drive the deflection block 26 to deflect away from the locking seat 22. The movable module 31 is used to drive the movable seat 24 to move toward the first fixed seat 21. The movable seat 24 is locked to the locking seat 22 by the deflection block 26. When it is necessary to adjust the hoisting height of the extension section 131, the locking seat 22 is released from the deflection block 26 by the drive mechanism 32 of the unlocking device 3, and the movable module 31 of the unlocking device 3 drives the movable seat 24 to move towards the first fixed seat 21. The extension section 131 and the hoisting section 132 are a sling.

[0059] Specifically, the movable seat 24 is movably mounted on the lifting device 11. After the unlocking device 3 releases the movable seat 24 from the locking seat 22, the movable module 31 drives the movable seat 24 to move towards the first fixed seat 21 on the lifting device 11, thereby shortening the extended section 131 between the movable seat 24 and the first fixed seat 21 to achieve the tilting of the workpiece 6. Alternatively, the movable seat 24 can be directly mounted on the locking seat 22. While the unlocking device 3 releases the movable seat 24 from the locking seat 22, the movable module 31 can clamp and fix the movable seat 24 and drive it towards the first fixed seat 21. Specifically, the driving mechanism 32 and the movable module 31 can be quickly connected. The unlocking device 3 can quickly unlock and drive the movable seat 24, reducing the need for additional lifting equipment, thus lowering costs, and quickly achieving the unlocking and driving objectives, thereby improving lifting efficiency.

[0060] See Figures 1 to 3In the first embodiment of the present invention, the locking seat 22 is a rack seat, and a plurality of rack grooves 23 are spaced apart on the rack seat. The deflection block 26 forms a rack body 262 that abuts against the bottom of the rack groove 23. The driving mechanism 32 includes a first telescopic driving member 321 disposed on the moving module 31 and a pressure plate 322 connected to the first telescopic driving member 321. The first telescopic driving member 321 is used to drive the pressure plate 322 to press down the deflection block 26 to deflect it, so that the rack body 262 is misaligned with the bottom of the rack groove 23. By setting a plurality of rack grooves 23, the different positions of the abutment between the rack body 262 and the plurality of rack grooves 23 can be controlled to adjust the different tilt angles required by the workpiece 6, which can meet the usage requirements of workpieces 6 of different sizes and improve versatility. Specifically, the telescopic direction of the first telescopic drive member 321 is vertical. When the telescopic end of the first telescopic drive member 321 moves downward, it can drive the pressure plate 322 to press down the deflection block 26, so that the rack body 262 and the bottom of the rack groove 23 are misaligned, thus releasing the lock. When the telescopic end of the first telescopic drive member 321 moves upward, it can drive the pressure plate 322 to be removed from the deflection block 26, so that the rack body 262 returns to contact with the bottom of the rack groove 23, thus re-locking.

[0061] Specifically, the rack seat extends along the lifting device 11 toward the first fixed seat 21. A pin 261 is inserted at the upper part of the middle of the deflection block 26 to ensure that the center of gravity of the deflection block 26 is below the pin 261. The pin 261, the deflection block 26, and the moving seat 24 can rotate, so that the rack body 262 set on the deflection block 26 in the natural state can stop at the lowest point. This ensures that the rack body 262 and the rack groove 23 can automatically abut against each other to lock the moving seat 24 without external force. This avoids instability caused by omissions in operation due to manual operation and further enhances the locking reliability of the rack seat.

[0062] See Figure 1 In the first embodiment of the present invention, the locking device 2 further includes a slide bar seat 25 disposed on the lifting device 11. The slide bar seat 25 is located below the locking seat 22, and the movable seat 24 has a sliding hole for the slide bar seat 25 to pass through. That is, the slide bar seat 25 has the function of guiding and supporting the movable seat 24.

[0063] Specifically, the slide bar seat 25 includes a slide bar body 252 and two mounting plates 251 respectively disposed at both ends of the slide bar body 252. The slide bar body 252 extends along the length of the lifting device 11. The movable seat 24 has a sliding hole through it. The movable seat 24 can slide on the slide bar body 252 through the sliding hole. The slide bar body 252 and the mounting plates 251 provide support and guidance for the movable seat 24, making the movement of the movable seat 24 more stable and smooth.

[0064] See Figures 1 to 3In the first embodiment of the present invention, the moving module 31 includes a first translation mechanism 311 and a clamping block 312 disposed on the first translation mechanism 311. A driving mechanism 32 is disposed on the clamping block 312. The moving seat 24 has clamping openings 241 on both opposite sides for the clamping block 312 to be inserted. The first translation mechanism 311 is used to drive the clamping block 312 to push the moving seat 24 to move on the slide bar seat 25. That is, the first translation mechanism 311 provides thrust for the moving seat 24 to move on the slide bar seat 25. The clamping opening 241, by docking with the clamping block 312, facilitates the clamping block 312 to be positioned and clamped on the moving seat 24, so that the moving seat 24 can achieve smooth sliding movement on the slide bar seat 25.

[0065] In addition, the movable module 31 may also have a gripper cylinder at the end of the first translation mechanism 311. The gripper cylinder is used to grip the movable seat 24 and the driving force of the first translation mechanism 311 causes the gripper cylinder to move the movable seat 24 toward the first fixed seat 21. The slide bar seat 25 includes, but is not limited to, the required setting. The gripper cylinder plays the role of gripping and fixing the movable seat 24.

[0066] Specifically, the moving module 31 also includes a second translation mechanism 313. The first translation mechanism 311 is mounted on the second translation mechanism 313. The second translation mechanism 313 is used to drive the first translation mechanism 311 to move closer to or away from the moving seat 24. Specifically, the second translation mechanism 313 is configured as a ball screw pair arranged in the front-back direction of the lifting device 11, and the first translation mechanism 311 is configured as a ball screw pair arranged in the left-right direction of the lifting device 11. The left-right direction of the lifting device 11 can be the extension direction of the rack seat, or the moving direction from the moving seat 24 toward the first fixed seat 21. The second translation mechanism 313 plays the role of adjusting the position of the clamping block 312 in the front-back direction to align with the clamping opening 241. The first translation mechanism 311 plays the role of driving the clamping block 312 to push the moving seat 24.

[0067] See Figure 1 In the first embodiment of the present invention, a fixed pulley 4 is provided on the first fixed base 21, the extended section 131 is connected to the lifting device 11 and extends to the movable base 24 around the lower side of the fixed pulley 4, and a movable pulley 5 is provided on the movable base 24. The lifting section 132 extends to the side of the movable base 24 away from the first fixed base 21 by passing around the upper side of the movable pulley 5. That is, the movement of the extended section 131 when it is extended and shortened is changed from sliding to rolling by the fixed pulley 4 and the movable pulley 5, which reduces the frictional loss of the extended section 131 and makes the movement of the extended section 131 smoother.

[0068] Specifically, the extended section 131 is positioned at the same height below the fixed pulley 4 and above the movable pulley 5. This ensures that as the movable pulley 5 approaches or moves away from the fixed pulley 4, the extended section 131 maintains a smooth relative movement with both the fixed pulley 4 and the movable pulley 5, thus extending the service life of the extended section 131. Alternatively, the fixed pulley 4 and the movable pulley 5 can be replaced with rotatable structures such as rollers or turntables to achieve the same effect.

[0069] See Figures 4 to 7 In the second embodiment of the present invention, the extended section 131 is a swivel rod, the locking device 2 is a locking pin, and the lifting device 11 has a second fixed seat 28 and a third fixed seat 29 arranged sequentially at intervals on one side of the fixed sling 12. One end of the swivel rod is rotatably mounted on the second fixed seat 28, and the other end of the swivel rod is detachably mounted on the third fixed seat 29 through the locking pin. The unlocking device 3 includes a second telescopic drive member 36 and a plug-in gripper 37 disposed on the second telescopic drive member 36. The second telescopic drive member 36 is used to drive the plug-in gripper 37 to grab the locking pin and pull it out from the third fixed seat 29. That is, the upper end of the pulled-out swivel rod is connected to the second fixed seat 28 and the lower end is connected to the lifting section 132. The swivel rod becomes part of the lifting section 132 of the movable sling 13, and the lifting height of the movable sling 13 is reduced, thereby achieving the purpose of tilting the workpiece 6. Only the lifting section 132 is a sling, and the extended section 131 is a rod.

[0070] Specifically, the side of the locking pin that is inserted into the third fixing seat 29 is provided with an elongated pin hole. The third fixing seat 29 is provided with a limit pin at the pin hole of the locking pin. When the locking pin is inserted or removed, the limit pin and the pin hole limit and guide the locking pin, so as to prevent the locking pin from falling off when it is pulled out of the third fixing seat 29 and to ensure that the locking pin is stable and does not deflect during the insertion and removal process.

[0071] See Figures 4 to 7 In the second embodiment of the present invention, the locking pin is made of ferromagnetic metal, and the insertion / removal gripper 37 is an electromagnet, which can easily change the magnetic force of the electromagnet to meet the requirements of different load conditions. In addition, the locking pin can also be made of other non-ferromagnetic metal, and the insertion / removal gripper 37 can be a gripper cylinder or a suction cup gripper. The gripper cylinder or suction cup gripper can clamp the protruding part of the locking pin and pull the locking pin out of the third fixed seat 29 by driving the second telescopic drive member 36, thereby releasing the lock of the rotating rod, so that the rotating rod becomes part of the lifting section 132, thereby reducing the lifting height of the lifting section 132 to achieve the purpose of tilting the workpiece 6.

[0072] See Figure 5 and Figure 6In the second embodiment of the present invention, the unlocking device 3 further includes a sliding mechanism 33, a swing mechanism 34 movably disposed on the sliding mechanism 33, and a support rod 35 disposed on the swing mechanism 34. The second telescopic drive member 36 is disposed on the sliding mechanism 33. The swing mechanism 34 is used to drive the support rod 35 to swing up and down to move closer to or away from the rotating rod. That is, the swing mechanism 34 drives the support rod 35 to rotate to abut against the bottom of the rotating rod to provide support for the rotating rod, preventing the locking pin from being pulled out from the third fixed seat 29 and the rotating rod. Due to the instantaneous downward force, the hoisted workpiece 6 will shake violently, ensuring the stability of the hoisting.

[0073] Specifically, the sliding mechanism 33 includes a mounting base 332 and a lead screw 331. The lead screw 331 is mounted on the base of the unlocking device 3, and the mounting base 332 is mounted on the lead screw 331. The lead screw 331 is arranged along the front-rear direction of the lifting device 11. When the lifting device 11 moves to the front of the unlocking device 3, the mounting base 332 can be moved forward by controlling the lead screw 331 to approach the rotating rod. The swing mechanism 34 includes a drive motor 341 and a swing rod 342. The drive motor 341 is mounted on the mounting base 332. On 32, the output shaft of the drive motor 341 is connected to one side of the swing rod 342 via a gear transmission structure. The support rod 35 is located at the other end of the swing rod 342, away from the side of the drive motor 341. That is, the drive motor 341 drives the swing rod 342 to rotate upward and causes the side of the support rod 35 to abut against the bottom of the rotating rod. The support rod 35 replaces the third fixed seat 29 to support the rotating rod. The motor drives the support rod 35 to rotate downward, so that the rotating rod rotates from a horizontal state to an inclined state in the first half of its stroke. Figure 5 As shown, the support rod 35 can abut against the side of the rotating rod, which can buffer the tilt of the workpiece 6. In the second half of the rotation of the rotating rod, when it is in the same straight line as the hoisting section 132, the support rod 35 disengages from the side of the rotating rod.
