[0002] Steel pipes are used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts; they are also an economical type of steel. Steel pipes can be divided into two main categories according to their production methods: seamless steel pipes and welded steel pipes. Welded steel pipes are further divided into straight seam welded pipes and spiral seam welded pipes. Welded steel pipes are classified according to their welding processes: furnace welded pipes, electric welded (resistance welded) pipes, and automatic electric arc welded pipes. They are also classified according to their welding forms: straight seam welded pipes and spiral welded pipes. Finally, they are classified according to their end shapes: round welded pipes and special-shaped (square, flat, etc.) welded pipes. Steel strip is the raw material for welded steel pipes, which are made by welding steel strips rolled into tubular shapes.

[0003] Existing tensioning devices with uncoiling mechanisms expand the strip outwards by a fixed distance during tensioning. However, the dimensions of each strip are not exactly the same, and their inner diameters also vary. Therefore, tensioning to a fixed distance imposes limitations on the tensioning device. The prior art, CN221790605U, discloses an uncoiling device for welded steel pipe strips, which addresses the aforementioned technical problem and provides a solution. This application offers a different approach to this problem.

[0004] Therefore, there is a need for a welded steel pipe strip uncoiling device to solve the problems mentioned in the background art. Utility Model Content

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5 This utility model provides a welding steel pipe strip uncoiling device, including a base plate 5, a support plate 4 fixed on the top side of the base plate 5, a support roller 3 rotatably connected to the top of the support plate 4, a top fixing component 2 provided on the side of the support roller 3, and a pressure regulating component 1 for injecting liquid into the support roller 3 at one end of the support roller 3. The top fixing component 2 includes an inner groove 203 opened on the side of the support roller 3, and multiple inner grooves 203 are provided and are equidistantly distributed. A top rod 201 is inserted into each of the multiple inner grooves 203. In use, the steel strip to be uncoiled is first... The strip coil is placed on the support roller 3. A certain amount of liquid is injected into the support roller 3 through the pressure regulating component 1, so that the support roller 3 has hydraulic pressure. The hydraulic pressure pushes the top fixing component 2 to clamp the steel strip coil placed on the support roller 3 at multiple points. The pressure regulating component 1 and the top fixing component 2 can be used to clamp steel strip coils with different inner diameters. The adjustable range is large and the clamping stability is high. It is better suited for clamping and fixing steel strip coils with different inner diameters, effectively solving the problem that the tensioning device has a large limitation of application when tensioned to a fixed distance value.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the top-fixing assembly 2 includes an inner cavity 204 located inside the support roller 3 and arranged along the length of the support roller 3. The inner groove 203 is connected to the inner cavity 204. A piston plate b202 is fixed to one end of the top rod 201 and fits tightly against the side wall of the inner groove 203. In operation, the inner cavity 204 has hydraulic pressure, which synchronously pushes multiple piston plates b202 to move within the inner groove 203. This causes multiple top rods 201 to extend out from the inner groove 203, thereby using multiple top rods 201 to perform multi-point stable clamping of the steel strip coil placed on the support roller 3. It can stably clamp steel strip coils with different inner diameters, has a large adjustable range, and high clamping stability. It is better suited for clamping and fixing steel strip coils with different inner diameters, effectively solving the problem that tightening to a fixed distance value would limit the applicability of the tensioning device.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the pressure regulating component 1 includes a liquid cylinder 101 fixed to one end of the support roller 3 and communicating with the inner cavity 204. A nut sleeve 103 is fixed inside the end of the liquid cylinder 101 away from the support roller 3. A threaded rod 104 inserted inside the liquid cylinder 101 is threadedly connected to the nut sleeve 103. A piston plate a102 that fits tightly against the inner wall of the liquid cylinder 101 is fixed to one end of the threaded rod 104. Both the liquid cylinder 101 and the inner cavity 204 are filled with a certain amount of liquid. In specific operation, by rotating the threaded rod 104, the piston plate a102 is moved inside the liquid cylinder 101, thereby pressing the liquid inside the liquid cylinder 101 into the inner cavity 204 through the piston plate a102, thereby adjusting the hydraulic pressure inside the inner cavity 204, so that the push rod 201 extends out of the inner groove 203 to different degrees.

[0027] Further as Figure 3 and Figure 5 As shown, it is worth noting that a rubber pad 205 is attached and fixed to one end of the top rod 201 located outside the support roller 3. In actual operation, the rubber pad 205 increases the friction between the end of the top rod 201 and the steel strip coil, thereby improving the clamping stability.

[0028] Further as Figure 1 and Figure 2 As shown, it is worth noting that the liquid cylinder 101 is rotatably connected to the support plate 4, a gear b9 is fixed on the outer wall of the liquid cylinder 101, a drive motor 7 is fixed on the side of the support plate 4, and a gear a8 that meshes with the gear b9 is fixed on the output end of the drive motor 7.

[0029] The solution has the following working process: First, the steel strip coil to be uncoiled is placed on the support roller 3. By rotating the threaded rod 104, the piston plate a102 is moved inside the liquid cylinder 101. The piston plate a102 then presses the liquid inside the liquid cylinder 101 into the inner cavity 204. The hydraulic pressure inside the inner cavity 204 is then adjusted. The hydraulic pressure synchronously pushes multiple piston plates b202 to move in the inner groove 203, causing multiple push rods 201 to extend from the inner groove 203. The multiple push rods 201 then provide multi-point stable clamping for the steel strip coil placed on the support roller 3, and can stably clamp steel strip coils with different inner diameters.

[0030] Further as Figure 3 As shown, it is worth noting that a handle rod 105 is fixed on the end of the threaded rod 104 away from the piston plate a102, and a rubber sleeve is fitted on the surface of the handle rod 105; in actual operation, the threaded rod 104 can be easily rotated by the handle rod 105, and the handle rod 105 has a long lever arm, making it easy to operate.

[0031] Further as Figure 1 and Figure 2 As shown, it is worth noting that the top surface of the base plate 5 has multiple symmetrically distributed screw holes 6; in actual operation, the base plate 5 is fixedly installed by installing bolts in the screw holes 6.

[0032] In summary: the hydraulically driven top-fixing component 2 provides multi-point stable clamping of the steel strip coil placed on the support roller 3. Furthermore, the combination of the pressure regulating component 1 and the top-fixing component 2 allows for stable clamping of steel strip coils with different inner diameters. The adjustable range is large, and the clamping stability is high, making it more suitable for clamping and fixing steel strip coils with different inner diameters. This effectively solves the problem that tensioning to a fixed distance value would result in a significant limitation in the applicability of the tensioning device.

[0033] The drive motor 7 can be purchased from the market. The drive motor 7 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
