Description

Technical Field

[0001] This invention relates to the field of pickling, galvanizing, and electrophoretic coating lifting equipment, and more specifically, to intelligent pickling, galvanizing, and electrophoretic coating lifting equipment. Background Technology

[0002] In existing technologies, pickling, galvanizing, and electrophoresis production lines commonly use flexible steel strips as the main support for the batch surface treatment of multiple thin tube-like workpieces. Bundles of thin tubes are constrained and suspended below a conductive beam by connecting the ends of the steel strips to form a closed loop or by using multi-point suspension. However, this steel strip suspension structure has significant geometric space utilization defects in practical applications. Because the thin tubes naturally slide down and accumulate at the lowest point of the steel strip's arc under gravity, if no dedicated support component is installed at this lowest point, the thin tubes in the bottom area will exhibit severe concentrated protrusion due to the lack of radial constraint. That is, the axial height of multiple thin tubes no longer remains aligned but instead presents a distinct downward arc distribution. This makes the vertical projection height of the entire bundle of thin tubes much greater than the sum of the diameters of individual thin tubes, resulting in a significant waste of the effective working space of the electrophoresis tank. The number of workpieces that can be processed in a single batch is rigidly limited, failing to meet the pursuit of maximizing equipment volume utilization in large-scale production.

[0003] The aforementioned technical bottlenecks further lead to a dual dilemma in actual production: process adaptability and operational convenience. On the one hand, different batches of tubes have different length specifications, diameter dimensions, or surface treatment requirements, which in turn require different support positions, support widths, and numbers of support plates. However, the support plates in existing equipment are mostly fixed structures or can only achieve very limited manual movement. They cannot quickly increase or decrease the number of support plates or adjust their lateral distribution spacing according to the actual hanging shape of the tube bundle. This results in a dilemma when facing the flexible production needs of multiple varieties and small batches, where the support plates are too dense, causing interference, or the support plates are insufficient, causing increased sagging. On the other hand, the adjustment of the support plates often requires operators to go deep into the narrow space at the edge of the groove and use tools to disassemble the fasteners. This is not only time-consuming but also difficult to guarantee adjustment accuracy, which seriously restricts the changeover efficiency of the production line and the overall utilization rate of the equipment. Therefore, it is urgent to develop an adaptive hanging device that can quickly reconstruct the support plate layout according to the tube bundle specifications and actively suppress the sagging deformation of the steel strip. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides an intelligent lifting device for pickling, galvanizing and electrophoresis to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an intelligent lifting device for pickling, galvanizing, and electrophoresis, comprising a lifting beam, a replacement mechanism, and a lateral movement mechanism.

The pull rod is inserted into the fixing tube.

[0009] Preferably, multiple sets of unidirectional grooves are symmetrically opened on the inner wall of the fixed tube, and a unidirectional block is slidably arranged in each set of unidirectional grooves, and a double-headed rod is hinged between every two adjacent unidirectional blocks.

A plurality of push blocks corresponding to the push rod are arranged in each synchronization ring, and the push blocks abut against the push rod.

[0013] Preferably, a rotating shaft is rotatably provided on both sides of the transverse beam, and a counterweight and a support plate are provided on both sides of the rotating shaft, with the support plates on both sides abutting against the steel strip.

[0014] Preferably, a motor is fixedly installed inside the lifting beam, the drive end of the motor is connected to a lead screw, a follower block is installed on the transverse beam, and the lead screw is threaded into the follower block.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an intelligent lifting device for pickling, galvanizing, and electrophoresis, which has the following beneficial effects: This invention, through an innovative modular pallet splicing and quick-locking mechanism, enables on-demand reconfiguration of the number and position of support units. It fundamentally solves the problem of traditional steel strip suspension methods being unable to adapt to different specifications of tube bundles due to inconvenient pallet fixing or adjustment. Its clamping assembly utilizes the interlocking of embedded blocks and grooves on both sides of the bottom block to achieve rapid lateral positioning. Combined with the pre-tensioning effect of the synchronizing rod and push spring, adjacent pallets fit tightly together to form a continuous support surface. Simultaneously, the self-locking assembly features an automatic locking design where the pull rod is inserted into the fixed tube, allowing for the installation and fixing of a pair of pallets without any tools. This enables operators to quickly increase or decrease the number of pallets and adjust their spacing on-site according to the total length and diameter of the tube bundle. This simplifies the previously time-consuming and labor-intensive changeover operation, requiring multiple personnel, to a single person completing the task within minutes, greatly improving the production line's response speed to multi-variety, small-batch tasks and the overall utilization rate of the equipment.

[0016] The self-locking assembly constructed in this invention is based on the unidirectional self-locking principle of unidirectional groove guidance and top spring energy storage, providing a highly reliable dual guarantee against loosening and unauthorized disassembly for pallet connection. When the pull rod is fully inserted into the fixed tube, multiple sets of unidirectional blocks are radially reset and clamped to the outer wall of the pull rod under the action of the top spring. Since the unidirectional groove is a unidirectional guiding structure, any pulling force that attempts to pull the pull rod outward will cause the unidirectional blocks to further wedge and produce a self-locking effect that tightens as it is pulled, ensuring that the pallet will never loosen under long-term vibration conditions. At the same time, the unlocking of this self-locking assembly can only be achieved by inserting a special unlocking sleeve into the control ring and rotating it. Furthermore, by adjusting the pre-contraction state of the unidirectional blocks near the pull rod inlet side, unauthorized pull rods can be prevented from passing through this set of unidirectional blocks, thus preventing unauthorized personnel from arbitrarily disassembling the installed pallet and also preventing unauthorized personnel from adding pallets and changing the support layout without authorization. This provides a physical-level control measure for process discipline and equipment safety on the production site.

[0017] The transverse movement mechanism of this invention actively controls the tension and support posture of the steel strip through electromechanical coordination, achieving adaptive hanging of tube bundles of different lengths and maximizing space utilization. It uses a motor-driven lead screw to drive the transverse beams on both sides to open and close precisely and synchronously along the slide rail. With the sliding guidance of the inclined groove and pin shaft, the two ends of the steel strip open or close smoothly. At the same time, the gravity-following design of the counterweight and support plate ensures that the steel strip maintains appropriate tension at any opening degree and does not twist. When the steel strip closes to support the tube bundle, multiple sets of support plates are evenly distributed along the length of the steel strip and elastically press the steel strip with an arched spring. This can adapt to the irregular contour and weight distribution differences at the bottom of the tube bundle, keeping the bottom of the entire bundle of thin tubes strictly flat. This fundamentally eliminates the problem of concentrated protrusion of the tube bundle caused by the sag of the lowest point of the steel strip in traditional hanging methods. Under the premise of keeping the effective height of the electrophoresis tank unchanged, the number of workpieces that can be processed in a single batch is increased, thereby increasing the equipment's production capacity.

[0018] This invention, while pursuing efficient changeover and space utilization, fully considers the reliability and ease of maintenance of the lifting device during long-term operation. The arched spring embedded in the bottom block of the pallet is made of corrosion-resistant elastic material, which can maintain stable elastic output even after long-term immersion in corrosive baths such as pickling, galvanizing, and electrophoresis, ensuring that the flexible clamping of the steel strip does not fail. The push springs at both ends of the synchronizing rod are always kept in a pre-compressed state, which can automatically eliminate the micro-movement gaps that may be caused by long-term vibration. All moving parts in the self-locking assembly are encapsulated in fixed tubes and extended tubes, effectively isolating them from the corrosion of the bath. At the same time, all modular units adopt the same interface standard. If any pallet or self-locking component is damaged, there is no need to replace the entire lifting device. Production can be quickly restored simply by disassembling the faulty unit with special tools and replacing the spare parts. This significantly reduces the types of spare parts inventory and maintenance costs, providing a highly reliable and low-consumption intelligent lifting solution for continuous electrophoresis production lines.

[0024] Please see Figures 1 to 9 This embodiment provides an intelligent lifting device for pickling, galvanizing, and electrophoresis. This device aims to solve the technical problems of existing steel strip hanging methods, which lack an adjustable support structure, resulting in drooping and protruding thin tubes, low space utilization, and the inability to quickly reconfigure the number and position of the support plates according to the specifications of the tube bundle. By integrating a replacement mechanism with modular rapid assembly and special tool authorization locking functions, and a transverse movement mechanism that can actively adjust the steel strip tension and support width, it achieves adaptive support for thin tube workpieces of various specifications, high-efficiency batch electrophoresis, and safe management to prevent accidental dismantling.

[0025] 1. Overall structure and initial state The pickling, galvanizing, and electrophoresis intelligent lifting device includes a lifting beam 11 as the main load-bearing component, as well as multiple replacement mechanisms and a set of transverse movement mechanisms 41 installed on the lifting beam 11. The replacement mechanism is used to flexibly assemble the support unit according to the length and quantity of the tube bundle and form a bottom support for the steel strip 22. It consists of a clamping component 21 and a self-locking component 31. The transverse movement mechanism 41 is used to drive the two ends of the steel strip 22 to move laterally to adjust the hanging width and open the steel strip 22 so that it can be fitted into the tube bundle.

[0026] 2. Composition of the core system 2.1 Clamping assembly 21 The clamping assembly 21 is the basic unit that constitutes the bottom support function. It achieves clamping of the steel strip 22 and support of the tube bundle through modular splicing. The assembly includes a flexible steel strip 22 and support plates 23 symmetrically clamped on both sides of the steel strip 22. Each support plate 23 has a bottom block 24 fixed at its lower end. An arched spring 25 is embedded inside the bottom block 24, and the arched top of the arched spring 25 elastically presses against the lower surface of the steel strip 22. Each bottom block 24 has an embedded block 26 on one side and an embedded groove 27 on the other side. Adjacent bottom blocks 24 are laterally positioned by the engagement of the embedded block 26 and the embedded groove 27. Two sets of coaxial through synchronous holes 28 are also opened between the two symmetrically arranged bottom blocks 24. Two synchronous rods 29 are respectively inserted into the corresponding synchronous holes 28. Each synchronous rod 29 has a push spring 210 sleeved at both ends, and the two push springs 210 respectively abut against the inner walls of the two ends of the synchronous hole 28.

[0027] 2.2 Self-locking component 31 The self-locking assembly 31 is used to lock two adjacent bottom blocks 24 together and ensure that installation and disassembly can only be completed using special tools. This assembly includes a central hole 32 and a fixing hole 33 coaxially formed in each bottom block 24. A fixing tube 35 is fixedly connected to the fixing hole 33 on one side of the bottom block 24, while a pull rod 34 passes through the fixing hole 33 on the other side of the bottom block 24. One end of the pull rod 34 is slidably inserted into the fixing tube 35. Multiple sets of axially extending unidirectional grooves 36 are symmetrically formed on the inner wall of the fixing tube 35. A unidirectional block 37 is slidably arranged in each set of unidirectional grooves 36, and adjacent unidirectional blocks 37 are hinged together by a double-headed rod 38. Each unidirectional block... The interior of block 37 has an internal groove 311, and a top spring 39 is provided in the internal groove 311. One end of the top spring 39 is equipped with a top rod 310. The top rod 310 can extend and abut against the inner wall of the unidirectional block 37. Both ends of the fixed tube 35 are fixed with an extension tube 312. A synchronization ring 313 is slidably arranged in each extension tube 312. Multiple push blocks 314 corresponding to the top rod 310 are fixed on the synchronization ring 313, and the push blocks 314 abut against the end of the top rod 310. The ends of the two extension tubes 312 are respectively threaded with control rings 315, and the inner end of the control ring 315 abuts against the synchronization ring 313. A special release sleeve 316 is also limited and connected in the center hole of the control ring 315.

[0028] 2.3 Transverse Mechanism 41 The lateral movement mechanism 41 is used to drive both ends of the steel belt 22 to move laterally along the lifting beam 11 to change the hanging width and assist in spreading the steel belt 22 to facilitate the insertion and release of the tube bundle. This mechanism includes slide rails 42 fixed to both ends of the lifting beam 11 and a transverse beam 43 slidably mounted on the slide rails 42. Multiple sets of rollers 44 are installed on the transverse beam 43, and the rollers 44 are rolled and embedded in the guide grooves of the slide rails 42. Inclined grooves 45 are provided at both ends of the transverse beam 43, through which the two ends of the steel belt 22 pass. The pin 46 is engaged in the inclined groove 45 and can slide along the inclined groove 45. Rotating shafts 47 are rotatably arranged on both sides of the transverse beam 43. Each rotating shaft 47 is fixed with a counterweight 48 and a support plate 49, and the support plates 49 on both sides elastically abut against the outer side wall of the steel belt 22. A motor 410 is fixed in the lifting beam 11. The drive end of the motor 410 is connected to a lead screw 411. A follower block 412 is fixed on the transverse beam 43. The lead screw 411 and the follower block 412 are threadedly connected.

[0029] 3. Working process and principle of the device The assembly, adjustment, and workflow of the intelligent lifting device are as follows: When dealing with electrophoresis tasks of different specifications of thin tubes, firstly, determine the required number of support plates 23 based on the total length of the tube bundle and the diameter of a single tube. The operator places the corresponding number of support plates 23 in pairs onto the steel belt 22. When installing each pair of support plates 23, first place the two bottom blocks 24 on both sides of the steel belt 22, aligning and engaging their inner blocks 26 with the inner grooves 27 of the adjacent bottom blocks 24. Simultaneously, insert the two synchronizing rods 29 into the synchronizing holes 28 on both sides, compressing the push spring 210 and generating a preload force to ensure that the two bottom blocks 24 fit tightly together. Subsequently, self-locking is performed. The operator pre-threads the fixing tube 35 into the fixing hole 33 of one side bottom block 24, and then sequentially passes the pull rod 34 of the other side bottom block 24 through the middle hole 32 and inserts it into the fixing tube 35. When the front end of the pull rod 34 enters the fixing tube 35, its outer wall first contacts the same-direction block 37 closest to the inlet. Since this group of same-direction blocks 37 is in a radially contracted state under the action of the top spring 39 and the top rod 310, the pull rod 34 can pass smoothly. As the pull rod 34 continues to go deeper, its front end reaches the next few groups of same-direction blocks 37 and pushes the same-direction blocks 37 to overcome the pressure of the top spring 39 along the same-direction groove 3. 6. Radial expansion: After the pull rod 34 is fully inserted, all the synchro blocks 37 are reset and locked onto the outer wall of the pull rod 34 under the action of the top spring 39. Since the synchro groove 36 is a one-way guiding structure, when the pull rod 34 is subjected to outward pulling force, the synchro blocks 37 will further wedge and generate self-locking, thereby firmly locking the two bottom blocks 34. This process does not require tools and is quick to operate. However, if disassembly is required, a special release sleeve 316 must be used. The operator inserts the release sleeve 316 into the control ring 315 and rotates it. The control ring 315 pushes the synchronization ring 313 and the push block 314 to move axially. The push block 314 pushes the top rod 31. The compression spring 39 causes the aligning block 37 to retract radially, releasing the locking of the pull rod 34. Only then can the pull rod 34 be pulled out to complete disassembly. This design ensures that only personnel with special tools can disassemble and assemble the tray 23, effectively preventing unauthorized adjustment. Furthermore, to prevent unauthorized assembly, it is only necessary to adjust the aligning blocks 37 on the side closest to the pull rod 34 to retract from each other, so that the distance between the aligning blocks 37 is less than the diameter between the pull rods 34. When the stop bar tries to be inserted, it will only press against the aligning block 37 and will not be inserted, thus creating a self-locking mechanism. Therefore, it not only prevents unauthorized adjustment but also ensures unauthorized assembly.

[0030] After all pallets 23 are assembled, the lifting device is moved as a whole to the tube bundle stacking area by a crane. The motor 410 is started to drive the lead screw 411 to rotate, which drives the two transverse beams 43 to move synchronously away from each other along the slide rail 42. The pins 46 at both ends of the steel strip 22 slide in the inclined groove 45 and force the steel strip 22 to gradually open. At the same time, the support plate 49 is always pressed against the outside of the steel strip 22 under the weight of the counterweight 48, which helps to keep the steel strip 22 taut. After the opening width of the steel strip 22 exceeds the total length of the tube bundle, the lifting device is lowered so that the upper surface of all pallets 23 is lowered. At the bottom of the tube bundle, the motor 410 reverses to drive the transverse beams 43 to move closer together, the steel strip 22 gathers, and the support plate 23 supports the entire bundle of tubes from bottom to top and keeps its bottom flat. Since the support plate 23 elastically presses the steel strip 22 through the arched spring 25, it can adapt to the slight weight distribution difference of the tube bundle. At the same time, multiple sets of support plates 23 are evenly distributed along the length of the steel strip 22, which effectively suppresses the sagging and protrusion of the lowest point of the steel strip 22, so that the overall height of the tube bundle is compressed to a minimum, thereby accommodating more workpieces in the electrophoresis tank with a limited height and maximizing the single batch processing capacity.

[0031] Working principle summary: This invention achieves on-demand reconfiguration of the number and position of support units through the rapid splicing technology of modular pallet 23 and self-locking component 31. The inclined self-locking and special tool unlocking mechanism ensures the controllability of adjustment authority. At the same time, the transverse movement mechanism 41 actively adjusts the tension of steel strip 22 and the support plate 49 assists in tensioning, enabling the lifting device to flexibly adapt to tube bundles of different specifications and significantly improve the space utilization of electrophoresis tanks. It provides an intelligent and highly adaptable hanging solution for pickling, galvanizing and electrophoresis production lines.
