Description

Technical Field

[0001] This utility model relates to the field of dip coating equipment technology, specifically to a lifting frame for dip coating. Background Technology

[0002] In industrial production, dip coating is widely used for the surface treatment of various metal products to give them good protective properties, decorative properties, and other special properties.

[0003] During dip coating, the hanger holding the workpiece must first be fixed to a lifting element. The lifting element then lowers the hanger and workpiece into the dip coating tank. To ensure the stability of the hanger during lifting, a positioning structure needs to be designed. However, it must be locked before each dip coating descent and unlocked after each repositioning for unloading, which is time-consuming and labor-intensive. Using an automatic positioning structure would necessitate adding an electrical control system, leading to inconvenient maintenance and a high failure rate.

[0004] The existing technology has not adequately addressed the above problems, causing difficulties for the normal operation of this field. Therefore, there is an urgent need for a rotary lifting device for dip coating to solve these problems. Utility Model Content

[0005] This utility model proposes a lifting frame for dip coating, which solves the problem in related technologies that the lifting device needs to be frequently locked and unlocked during dip coating, which is time-consuming and labor-intensive.

[0006] The technical solution of this utility model is as follows: A lifting frame for dip coating includes a frame, a dip coating tank, a lifting rail, a lifting device, a crossbeam, and a swing lock. The lifting rail is slidably and vertically arranged relative to the frame. The dip coating tank is located below the lifting rail. The lifting device is movable relative to the lifting rail. The crossbeam is mounted on the frame. The swing lock is hinged to the lifting rail in the middle. The swing lock has a first end and a second end. The first end has a locking part, which is used to block the movement of the lifting device. After the lifting rail is raised or lowered, the crossbeam abuts against or releases the second end of the swing lock to drive the swing lock to swing.

[0007] Optionally, the lifting track is in the shape of a hollow square tube, and the bottom wall has a through groove running along its own length. The top wall of the lifting track has a lock hole. After the swing lock swings, the lock part enters or disengages from the lock hole.

[0008] Optionally, the lifting device includes a bracket, rollers, connectors, a hanger, and a lifting ring. The bracket is movably disposed within the lifting track, the rollers are rotatably disposed on the bracket, the two ends of the connector are respectively used to hinge with the bracket and the hanger, and there are at least two connectors. The lifting ring is used to be disposed on the hanger.

[0009] Optionally, rollers are rotatably mounted on both sides of the bracket, and the rollers abut against the inner wall of the lifting track.

[0010] Optionally, the connecting member includes a first vertical rod, a second horizontal rod, and a second vertical rod. The top end of the first vertical rod is hinged to the bracket, and the bottom end is hinged to the middle of the second horizontal rod. The first vertical rod is located in the through groove. There are two second vertical rods. The top ends of the two second vertical rods are respectively hinged to the two ends of the second horizontal rod, and the bottom ends of the two second vertical rods are both hinged to the hanger.

[0011] Optionally, it also includes a lifting frame, a lifting chain, and a lifting sprocket. The lifting frame is slidably mounted on the frame, the lifting track is mounted on the lifting frame, and the lifting sprocket is rotatably mounted on the frame. There are multiple lifting sprockets, and the lifting chain is sleeved on the multiple lifting sprockets. One end of the lifting chain is connected to the lifting track, and the other end is used to connect to the hoist drive unit.

[0012] Optionally, it also includes a counterweight, which is disposed on the lifting chain, and the counterweight and the lifting frame are respectively located on both sides of the frame.

[0013] Optionally, the lifting frame is triangular, the lifting frame has a slider, the frame has a slide rail, and the slider is slidably disposed on the slide rail.

[0014] Optionally, the lifting ring is V-shaped.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] Under normal conditions, the crossbeam abuts against the second end of the swing lock. At this time, the first end of the swing lock is raised, and the lock is located above the lifting device. It does not obstruct the lifting device, and the lifting device can move freely within the lifting track.

[0017] As the lifting track begins its descent for the dip-coating operation, the crossbeam gradually disengages from the second end of the swing lock. Once the lifting track has descended a certain distance, the crossbeam no longer presses against the second end of the swing lock. At this point, the swing lock begins to swing around its central hinge point under its own weight, gradually moving into the path of the lifting device. This effectively blocks the lifting device within the lifting track, fixing it in place during the lifting process and preventing swaying.

[0018] After the dip coating is completed, the lifting track begins to rise. When it rises to a certain height, the crossbeam contacts and presses against the second end of the swing lock again, causing the first end of the swing lock to lift up. The lifting part no longer obstructs the lifting device, and the lifting device can move freely within the lifting track, facilitating unloading.

[0019] This design, combining the swing lock with the crossbeam, achieves automatic stabilization of the lifting device during lifting. When the lifting track descends, no additional power or complex control devices are needed; the swing lock itself moves automatically into the lifting device's path, blocking it and ensuring it doesn't move on the lifting track due to unexpected external forces or swaying. This design is relatively simple, consisting only of the swing lock, crossbeam, and locking mechanism, without complex electronic control or hydraulic drive systems, thus reducing equipment failure rates and maintenance costs.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Reference Figures 1-4 This is the first embodiment of the present invention, which proposes a lifting frame for dip coating, including a frame 1, a dip coating tank 2, a lifting rail 3, a lifting device 4, a crossbeam 5, and a swing lock 6. The lifting rail 3 is slidably raised and lowered relative to the frame 1. The dip coating tank 2 is located below the lifting rail 3. The lifting device 4 is movable relative to the lifting rail 3. The crossbeam 5 is mounted on the frame 1. The swing lock 6 is hinged to the lifting rail 3 in the middle. The swing lock 6 has a first end and a second end. The first end has a locking part 7, which is used to block the movement of the lifting device 4. After the lifting rail 3 is raised and lowered, the crossbeam 5 abuts against or releases the second end of the swing lock 6 to drive the swing lock 6 to swing.

[0031] In this embodiment, under normal conditions, the crossbeam 5 abuts against the second end of the swing lock 6. At this time, the first end of the swing lock 6 is raised, and the lock part 7 is located above the lifting device 4, without obstructing the lifting device 4. The lifting device 4 can move freely within the lifting track 3.

[0032] As the lifting track 3 begins its descent for the dip-coating operation, the crossbeam 5 gradually disengages from the second end of the swing lock 6. Once the lifting track 3 has descended a certain distance, the crossbeam 5 no longer presses against the second end of the swing lock 6. At this point, the swing lock 6 begins to swing around its central hinge point under the weight of its locking part 7. The locking part 7 gradually moves onto the path of the lifting device 4, effectively blocking the lifting device 4 within the lifting track 3. This fixes the lifting device 4 in its current position during the lifting process, preventing swaying during lifting.

[0033] After the dip coating is completed, the lifting track 3 begins to rise. When it rises to a certain height, the crossbeam 5 contacts and presses against the second end of the swing lock 6 again, causing the first end of the swing lock 6 to lift up. The lock part 7 lifts up and no longer blocks the lifting device 4. The lifting device 4 can then move freely within the lifting track 3, facilitating unloading.

[0034] The design of this swing lock 6 in conjunction with the crossbeam 5 achieves automatic stabilization of the lifting device 4 during lifting. When the lifting track 3 descends, no additional power or complex control devices are required; the swing lock 6, relying on its own weight, automatically moves the locking part 7 onto the path of the lifting device 4, blocking it and ensuring that the lifting device 4 will not move on the lifting track 3 due to unexpected external forces or swaying. This design has a relatively simple structure, consisting only of the swing lock 6, crossbeam 5, and locking part 7, without complex electronic control or hydraulic drive systems, reducing equipment failure rate and maintenance costs.

[0035] Furthermore, the lifting track 3 is in the shape of a hollow square tube, and the bottom wall has a through groove that runs through its own length. The top wall of the lifting track 3 has a lock hole 8. After the swing lock 6 swings, the lock part 7 enters or disengages from the lock hole 8.

[0036] In this embodiment, the hollow square tube structure of the conveying track encloses the roller 402 and the bracket 401, effectively blocking interference from dust, debris, and other impurities in the external environment. The through groove on the bottom wall of the lifting track 3 provides ample space for the lifting device 4 to move, allowing it to freely adjust its posture within the through groove during installation.

[0037] During the dip coating process, the lifting track 3 descends, and the crossbeam 5 gradually disengages from the second end of the swing lock 6. At this time, the swing lock 6 begins to swing around the central hinge point under the weight of its locking part 7, and the locking part 7 gradually enters the lock hole 8, thereby blocking the lifting device 4 within the lifting track 3 and fixing the lifting device 4 in its current position during the lifting process. After the dip coating is completed, when the lifting track 3 rises to a certain height, the crossbeam 5 contacts and presses against the second end of the swing lock 6 again, causing the first end of the swing lock 6 to lift up, the locking part 7 to disengage from the lock hole 8, and the lifting device 4 can then move freely within the lifting track 3.

[0038] Furthermore, the lifting device 4 includes a bracket 401, a roller 402, a connector 403, a hanger 404, and a lifting ring 405. The bracket 401 is movably disposed within the lifting track 3, the roller 402 is rotatably disposed on the bracket 401, the two ends of the connector 403 are respectively used to hinge with the bracket 401 and the hanger 404, and there are at least two connectors 403. The lifting ring 405 is used to be disposed on the hanger 404.

[0039] In this embodiment, when the lifting device 4 is installed, at the instant it reaches the designated position on the lifting track 3 and stops moving, it will tend to sway due to inertia. However, since the connecting piece 403 connects the support 401 and the hanger 404 in a hinged manner, this hinged structure allows the hanger 404 to swing slightly relative to the support 401 within a certain range. Through the buffering effect of the hinged structure, this swaying energy is effectively dispersed, avoiding excessive impact on the entire lifting device 4 structure. Moreover, since at least two connecting pieces 403 are provided, the hanger 404 can be stably connected and supported from different positions.

[0040] Furthermore, rollers 402 are rotatably mounted on both sides of the bracket 401, and the rollers 402 abut against the inner wall of the lifting track 3.

[0041] In this embodiment, when installing the lifting device 4, the rollers 402 on both sides of the support 401 of the lifting device 4 roll forward along the inner wall of the lifting track 3. The lifting device 4 carries the workpiece and moves at a stable speed on the lifting track 3. The rolling friction between the rollers 402 and the inner wall of the lifting track 3 ensures the smooth movement of the lifting device 4 and prevents jamming or deviation. When the locking part 7 is inserted into the locking hole 8, it directly blocks the rollers 402. There are two sets of rollers 402. In this solution, it is preferable to have two locking parts 7, which are located between the two rollers 402, thereby restricting the rollers 402 from rolling to the sides.

[0042] Furthermore, the connector 403 includes a first vertical rod 4031, a horizontal rod 4032, and a second vertical rod 4033. The top end of the first vertical rod 4031 is hinged to the bracket 401, and the bottom end is hinged to the middle of the horizontal rod 4032. The first vertical rod 4031 is located in the through groove. There are two second vertical rods 4033. The top ends of the two second vertical rods 4033 are respectively hinged to the two ends of the horizontal rod 4032, and the bottom ends of the two second vertical rods 4033 are both hinged to the hanger 404.

[0043] In this embodiment, when the support 401 reaches the designated position and stops moving, the lifting device 4 as a whole still tends to continue moving forward due to inertia. The top of the first vertical rod 4031 of the connector 403 is hinged to the support 401, and the bottom is connected to the middle of the horizontal rod 4032. The second vertical rod 4033 connects the horizontal rod 4032 and the hanger 404. A parallelogram structure is also formed between the horizontal rod 4032, the two second vertical rods 4033, and the hanger 404. In this way, the inertial force is effectively distributed throughout the connector 403, avoiding structural damage or instability caused by the concentration of inertial force in a certain part. This design of the connector 403, which disperses the oscillation, can effectively maintain the overall stability of the lifting device 4.

[0044] Furthermore, it also includes a lifting frame 9, a lifting chain 10, and a lifting sprocket 14. The lifting frame 9 is slidably mounted on the frame 1, the lifting track 3 is mounted on the lifting frame 9, and the lifting sprocket 14 is rotatably mounted on the frame 1. There are multiple lifting sprockets 14, and the lifting chain 10 is sleeved on multiple lifting sprockets 14. One end of the lifting chain 10 is connected to the lifting track 3, and the other end is used to connect to the hoist drive unit.

[0045] In this embodiment, when the lifting rail 3 needs to be raised or lowered, the motor of the hoist drive unit starts, driving one end of the lifting chain 10 connected to it to begin winding or unwinding. The lifting chain 10 is sleeved between multiple lifting sprockets 14 rotating on the frame 1. Since one end of it is connected to the lifting frame 9 where the lifting rail 3 is located, the lifting frame 9 begins to perform stable lifting and lowering operations along the frame 1 as the chain moves. When the workpiece needs to be immersed in the dip coating tank 2, the lifting frame 9 descends smoothly under the traction of the lifting chain 10. At this time, the lifting rail 3 descends together with the lifting frame 9, ensuring that the workpiece on the lifting device 4 can accurately enter the dip coating tank 2.

[0046] Throughout the descent, due to the support and guidance provided by multiple lifting sprockets 14 to the lifting chain 10, the lifting frame 9 and the lifting track 3 will not experience any swaying, deviation, or other instability. After the dip coating is completed, the winch drive unit reverses, the lifting chain 10 moves in the opposite direction, and the lifting frame 9 drives the lifting track 3 to rise at the same stable speed, returning to the initial position for the next dip coating operation.

[0047] Furthermore, it also includes a counterweight 11, which is disposed on the lifting chain 10, and the counterweight 11 and the lifting frame 9 are respectively located on both sides of the frame 1.

[0048] In this embodiment, when processing the dip coating task, as the lifting frame 9 begins to descend, it drives one side of the lifting chain 10 to move downwards. At the same time, the counterweight 11 located on the other side of the frame 1 moves upwards along the frame 1. Throughout the entire lifting process, both sides of the frame 1 maintain stable force, avoiding problems such as deformation of the frame 1 and uneven wear of the chain due to uneven force, thereby ensuring the long-term stable operation of the production line and production accuracy.

[0049] Furthermore, the lifting frame 9 is triangular, and the lifting frame 9 has a slider 12. The frame 1 has a slide rail 13, and the slider 12 is slidably disposed on the slide rail 13.

[0050] In this embodiment, the lifting frame 9 has a triangular structure, which, thanks to its stable structure, can withstand significant weight and stress. The slider 12 and the slide rail 13 are tightly fitted together, preventing any shaking, jamming, or disengagement, thus ensuring the stable lifting of the lifting track 3. Throughout the process, the high-strength structure of the triangular lifting frame 9 and the stable sliding cooperation between the slider 12 and the slide rail 13 guarantee the reliability and safety of the lifting operation.

[0051] Furthermore, the lifting ring 405 is V-shaped.

[0052] In this embodiment, when the hook needs to be installed on the lifting ring 405 to suspend the workpiece, since the lifting ring 405 has a V-shaped structure, the connecting part of the hook is placed in the groove of the lifting ring 405. The hook can maintain a relatively fixed position in the lifting ring 405 and will not easily fall off or shift.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
