Technical Field
[0001] The utility model relates to the technical field of channel steel hoisting device, in particular to a portable special hoisting device for channel steel. Background Art
[0002] Channel steel is a long steel strip with a grooved cross section, which is mainly used in building structures, mechanical equipment, and vehicle manufacturing. According to different shapes and sizes, channel steel can be divided into many types, such as ordinary channel steel, light channel steel, H-shaped channel steel, etc. During production and manufacturing, it is necessary to transport the channel steel to the designated location for subsequent processing according to production needs.
[0003] At present, when lifting channel steel, steel wire ropes / slings or electromagnets are often used to lift channel steel. When lifting channel steel with steel wire ropes / slings, the steel wire ropes / slings are generally tied to the grooves of the channel steel, and the channel steel is lifted by hanging the steel wire ropes / slings. However, since the steel wire ropes / slings are flexible objects and due to the special structure of the channel steel, the channel steel will flip uncontrollably during the lifting process, which not only causes uncontrollable safety hazards to operators, equipment, etc., but also requires an additional flipping process after the channel steel is flipped, which increases unnecessary labor and affects the overall production efficiency.
[0004] The use of electromagnets to lift channel steel requires high quality for both the electromagnet and the surface of the channel steel, otherwise it is very easy to fall during the lifting process, causing serious safety accidents. In addition, in order to meet the magnetic attraction quality requirements, the cost of the electromagnet is high and the device structure is relatively complex, which makes it difficult to achieve the requirements of fast and convenient lifting using electromagnets, affecting production efficiency and increasing production costs.
[0005] Therefore, in order to solve the problems in the prior art that the channel steel lifting operation is inconvenient, easily leads to safety accidents, and has low lifting efficiency and increased production costs, it is now necessary to provide a portable channel steel special lifting device. Utility Model Content

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] The utility model specifically provides a portable special lifting device for channel steel, which can quickly and conveniently lift the channel steel, ensure the stability of the channel steel during the lifting process, improve the lifting efficiency, and ensure the lifting safety. The special lifting device for channel steel includes a hanging plate, a first positioning hole is provided on the upper part of the hanging plate, a first reinforcement ring is provided on the first positioning hole, and the first reinforcement ring is concentrically arranged with the first positioning hole; a second positioning hole is provided on the lower part of the hanging plate, a second reinforcement ring is provided on the second positioning hole, and the second reinforcement ring is concentrically arranged with the second positioning hole; a limiting shaft is movably provided in the second positioning hole; a first U-shaped hook and a second U-shaped hook for hanging the channel steel are respectively provided on both sides of the hanging plate, and the limiting shaft is arranged above the channel steel; a reinforcement plate is provided between the first U-shaped hook and the second U-shaped hook.
[0009] The principles and advantages of this solution are:
[0010] By setting the first reinforcement ring and the second reinforcement ring, the hanging strength of the hanging plate is increased to ensure that it can meet the hanging strength requirements of channel steels of various sizes. At the same time, the two U-shaped hooks can match the grooves of the special structure of the channel steel, so that one end of the channel steel can be directly hooked in the U-shaped hook, and the channel steel can be stabilized from both ends to prevent the channel steel from flipping during the lifting process, thereby reducing the flipping process, improving production efficiency, and reducing the labor intensity of operators. A limit shaft is used above the channel steel to press the top of the channel steel, and the gravity of the channel steel itself is used to stably hoist the channel steel in the U-shaped hook, thereby preventing the channel steel from falling off during the lifting process and improving the stability and safety of the channel steel lifting.
[0011] At the same time, this solution has a simple structure, quick operation, and can be applied to the lifting of channel steels of various sizes. It has high versatility, effectively reduces production costs and labor costs, and improves overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] This embodiment is basically as shown in the attached Figure 1 As shown: A portable channel steel special lifting device can reasonably set the lifting device size according to the channel steel size, realize the lifting of channel steels of multiple sizes and specifications, and improve the versatility and convenience of the channel steel lifting device. In this embodiment, the channel steel is pressed tightly by its own gravity during the lifting process to prevent the channel steel from falling off. The structure is simple, the operation is convenient, and the stability and safety are effectively improved. The portable channel steel special lifting device includes a lifting plate 1 with an overall square structure. The upper part of the lifting plate 1 is a conical structure. Figure 2 As shown, a first positioning hole 2 is provided at the upper conical structure end of the hanging plate 1. A first reinforcement ring 3 is welded on the front surface of the first positioning hole 2, that is, the front surface of the hanging plate 1. In this embodiment, the first reinforcement ring 3 is concentrically arranged with the first positioning hole 2. The first reinforcement ring 3 can be set as an ordinary steel ring with a thickness of 15-25mm and an outer diameter of 50-90mm. The special sling is hoisted on the lifting device through the first positioning hole 2, and the first reinforcement ring 3 is used to increase the hanging strength of the upper part of the hanging plate 1, thereby ensuring the stability of the hoisting and preventing it from falling, while reducing the overall weight of the sling, making it easier to operate.
[0020] Combined with Figure 2 As shown, the lower part of the hanging plate 1 is a square structure, and a second positioning hole 4 is opened at the lower part of the hanging plate 1. Figure 3 As shown, a second reinforcing ring 5 is welded on the rear surface of the second positioning hole 4, that is, on the rear surface of the hanging plate 1. In this embodiment, the second reinforcing ring 5 is concentrically arranged with the second positioning hole 4. The second reinforcing ring 5 can be arranged as an ordinary steel ring with a thickness of 20-45 mm and an outer diameter of 60-100 mm. The second reinforcing ring 5 increases the hanging strength of the second positioning hole 4 and improves the stability of the limiting shaft 6.
[0021] As attached Figure 1 and attached Figure 3As shown, a limit shaft 6 is movably installed in the second positioning hole 4. In this embodiment, a fixing seat 7 is integrally formed at one end of the limit shaft 6, and the limit shaft 6 is inserted into the second positioning hole 4 from the rear surface of the hanging plate 1, and is fixedly installed on the second reinforcement ring 5 through the fixing seat 7, so as to clamp the channel steel 10 from above. In this embodiment, the axial length of the limit shaft 6 is greater than half of the width of the hoisted channel steel 10 workpiece, so as to ensure the clamping force of the channel steel 10, ensure the stability of the channel steel 10 during the hoisting process, and avoid falling off and causing safety accidents.
[0022] As attached Figure 2 As shown, a first ear piece 11 and a second ear piece 12 having an overall rectangular structure are integrally formed on both sides of the hanging plate 1. In this embodiment, the first ear piece 11 and the second ear piece 12 have the same structure and the same size. Figure 1 As shown, a first U-shaped hook 8 is welded on the first ear piece 11, and a second U-shaped hook 9 is welded on the second ear piece 12. In this embodiment, the first U-shaped hook 8 and the second U-shaped hook 9 have the same structure and size, and are welded on both sides of the hanging plate 1 relative to each other.
[0023] Combined with Figure 4 As shown, the first U-shaped hook 8 includes a first long arm end 13 and a first short arm end 14, one end of which is connected to form a U-shaped structure. The second U-shaped hook 9 includes a second long arm end 15 and a second short arm end 16, one end of which is connected to form a U-shaped structure. A first limiting hole 17 is provided at the upper portion of the first long arm end 13, and the first U-shaped hook 8 is welded to the first ear piece 11 through the first limiting hole 17. A second limiting hole 18 is provided at the upper portion of the second long arm end 15, and the second U-shaped hook 9 is welded to the second ear piece 12 through the second limiting hole 18. The U-shaped hook is fixedly mounted on both sides of the hanging plate 1 through the ear pieces to ensure the stability of the U-shaped hook. At the same time, the channel steel can be hung by the U-shaped hooks on both sides, and the channel steel can be stabilized in the hook groove of the U-shaped hook to avoid the overturning of the channel steel and improve the stability of the channel steel lifting process.
[0024] A reinforcing plate 19 is welded between the first U-shaped hook 8 and the second U-shaped hook 9. In this embodiment, the two ends of the reinforcing plate 19 are respectively welded between the first short arm end 14 and the second short arm end 15, and two through holes 20 are also arranged in parallel on the reinforcing plate 19. The reinforcing plate 19 can improve the lifting strength, meet the support strength of the channel steel, and ensure the stability of the sling. At the same time, the through holes can reduce the overall weight of the sling, and the structure is simpler and more reliable, which improves the overall safety and stability of the sling, can be applied to the lifting and hanging of various channel steels, and improve the lifting efficiency.
[0025] The specific implementation process is as follows:
[0026] As attached Figure 1 To Attachment Figure 5As shown in the figure, firstly, according to the size range of the factory channel steel, set a reasonable hoisting tool size so that the hoisting tool can meet the hoisting requirements of various channel steels. Figure 5 As shown, first place the channel steel lifting device on the lifting device through the first positioning hole 2, and then use a tool such as a crowbar to pry up the channel steel 10 at 1 / 2 of the length of the channel steel to be lifted. Insert the U-shaped hook end of the lifting device into the pried lower end of the channel steel 10, so that one end of the channel steel 10 is embedded in the first U-shaped hook 8 and the second U-shaped hook 9. Finally, insert the limit shaft 6 from the back of the second positioning hole 4, so that the working surface of the limit shaft 6 is pressed on the top of the channel steel 10, and the channel steel 10 is pressed from above. Through the self-gravity of the channel steel 10, the channel steel 10 will be fixed in the U-shaped hook, ensuring the stability of the channel steel during lifting, preventing the channel steel from flipping and falling off, and the operation is simple and convenient, which effectively improves the efficiency of channel steel lifting.
[0027] In this embodiment, the size of the sling is reasonably set according to the size of the channel steel, so that the sling can be used for lifting channel steels of various sizes, thereby improving the versatility of the sling and reducing the manufacturing cost of the sling. In addition, in this embodiment, the sling has a simple structural design and is easy to operate, and can be quickly installed and disassembled, ensuring the safety and efficiency of the lifting process.
[0028] In this embodiment, the channel steel is fixed in the hook directly by the U-shaped hook by utilizing its own gravity, and the channel steel is further clamped by the limiting shaft 6 at the upper end, thereby ensuring the stability and safety of the channel steel lifting and avoiding the channel steel from flipping over during the lifting process. This saves the subsequent flipping process, improves the lifting operation efficiency, reduces the labor intensity of the operators, effectively reduces the production cost, and improves the production efficiency.
