An adjustable lifting device for self-locking lifting of sheet metal

Abstract

This utility model relates to the field of lifting equipment technology, specifically to an adjustable self-locking lifting device for sheet metal. It addresses the problem that existing lifting devices easily deform and destabilize thin copper electrolytic sheets during transport, limiting lifting efficiency. The device includes a stainless steel screw, nut, U-shaped lifting lug, limiting groove, and stainless steel bracket. During operation, the screw is unscrewed, allowing the sheet metal to be inserted into the limiting groove for self-locking and clamping. Finally, the screw and nut are tightened to hold the sheet metal, which is then lifted using the U-shaped lifting lug. This effectively expands the application range of the device for processing and transporting various thin sheet metals, improving the stability and safety of the sheet metal lifting and transportation process.

Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an adjustable lifting equipment for self-locking lifting of plates. Background Technology

[0002] In the copper electrolysis production process, with the continuous improvement and development of high-tech copper electrolysis, the processing and transportation quality of various plates has gradually become apparent, seriously hindering the improvement of process technology. For example, if the casting and transportation of copper anode plates are uneven, it is difficult to ensure the stability of the plates during loading and transportation, and they are prone to tipping over. This usually results in surface wear or scratch damage, which in turn increases the difficulty of loading the copper anode plates into the tank, ultimately causing fluctuations in various process indicators during the copper electrolysis process. However, when dealing with thinner plates, such as the conductive plates between copper electrolytic cells, which are typically made from high-purity cathode copper and are soft with a processing thickness of 10-15mm, the replacement of these conductive plates depends on either electrolysis efficiency or surface quality. On one hand, most copper electrolysis manufacturers use a needle cloth to wipe the areas where the cathode, anode, and conductive plates contact each other when the cathode copper is removed from the cell. Over time, this can wear down the convex conductive plates, reducing the contact area and thus decreasing current transmission efficiency and increasing power consumption. Therefore, using an acidic solution to dissolve surface crystals can ensure the integrity of the conductive plate surface. On the other hand, when transporting and replacing softer conductive plates, smooth handling or replacement is crucial for ensuring the surface quality of the plates. Utility Model Content

[0003] This invention provides an adjustable lifting device for self-locking lifting of sheet metal to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable lifting device for self-locking lifting plates includes a U-shaped bracket, with multiple screws adjustable on the open side of the U-shaped bracket, a U-shaped lifting lug fixed on the back side of the U-shaped bracket, and a limiting groove formed on the inner side of the U-shaped bracket.

[0005] Furthermore, the U-shaped card holder has multiple nuts fixedly installed on its open side, and the screw is rotatably disposed within the nuts.

[0006] Furthermore, a boss is fixedly provided on the back side of the U-shaped card holder, and multiple mounting holes are provided on the boss, with the U-shaped lifting lugs fixedly installed in the mounting holes.

[0007] This utility model has the following beneficial effects: This utility model provides an adjustable lifting device for self-locking sheet metal, including a stainless steel screw, nut, U-shaped lifting lug, limiting groove, and stainless steel bracket. This ensures that during operation, by unscrewing the screw, the sheet metal is simultaneously inserted into the limiting groove, creating a self-locking and clamping effect. Finally, the screw and nut are tightened to clamp the sheet metal, and the U-shaped lifting lug is used for lifting. This effectively expands the application range of this lifting device for processing and transporting various thin sheet metals, improves the stability and safety of the sheet metal lifting and transportation process, and solves the problem that existing lifting devices easily deform and cause unstable lifting when transferring thin copper electrolytic sheets, thus limiting the efficiency of sheet metal lifting.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1 As shown, an adjustable lifting device for self-locking lifting plates includes a U-shaped bracket 4. The opening side of the U-shaped bracket 4 is equipped with multiple screws 1. The back side of the U-shaped bracket 4 is fixedly equipped with a U-shaped lifting lug 3, and the inner side of the U-shaped bracket 4 is provided with a limiting groove 5.

[0012] The U-shaped card holder 4 has multiple nuts 2 fixedly installed on its open side, and the screw 1 is rotatably installed inside the nuts 2.

[0013] The back side of the U-shaped card holder 4 is fixedly provided with a boss 6, and multiple mounting holes 7 are opened on the boss 6, and the U-shaped lifting lug 3 is fixedly installed in the mounting holes 7.

[0014] All components of this lifting device are made of 316L stainless steel.

[0015] In practical applications, this lifting device features a simple structure, ease of processing, high durability, and convenient operation. During use, the screw 1, nut 2, U-shaped lifting lug 3, and limiting groove 5 constituting the lifting device are all made of 316L stainless steel, ensuring the device's service life during sheet metal processing and lifting. When assembling the sheet metal with the lifting device, simply keep the sheet metal stationary, insert it into the limiting groove 5 until it reaches the inside of the locking mechanism, ensuring the sheet metal is firmly secured within the limiting groove 5. Then, tighten the screw 1 until it reaches the surface of the sheet metal. Since the self-locking limiting effect of this device depends on the tightness of the screw 1, this ensures that the device... To fully accommodate and prevent damage to the sheet material surface, avoid locking the screw 1 to the sheet material. After the limiting groove 5 is assembled with the sheet material, the crane can be connected to the U-shaped lifting lug 3. To ensure the stability of the lifting device, four identical lifting devices should be arranged at the four corners of the two parallel sides of the sheet material. This arrangement can reduce damage to the sheet material and overload damage to the lifting devices. After each use, loosening the screw 1 will detach the lifting device from the sheet material, thus effectively ensuring the stable lifting of the sheet material and protecting the surface quality of the sheet material from damage during processing and transportation. It can be applied to various sheet material processing and transportation industries, therefore, this lifting device has good practicality.
