Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of auxiliary production equipment for spiral welded pipes, and more specifically, to a delivery machine for spiral welded pipe production. Background Technology

[0002] Spiral welded pipe is a type of pipe manufactured by rolling low-carbon structural steel or low-alloy structural steel strips into a pipe blank at a specific spiral angle (i.e., forming angle) and then welding the seam. This process allows for the production of large-diameter steel pipes from relatively narrow steel strips, with specifications expressed as outer diameter multiplied by wall thickness. During production, spiral welded pipes must meet relevant regulations regarding hydrostatic testing, weld tensile strength, and cold bending performance to ensure product quality.

[0003] In the production of spiral welded pipes, delivery machines play a crucial role. However, existing delivery machines generally suffer from a significant problem: they cannot flexibly adapt to the delivery needs of spiral welded pipes of different sizes. In actual production, factories often need to produce spiral welded pipes of multiple specifications, but existing delivery machines can only handle single-size spiral welded pipes. This means that when producing different specifications of products, factories have to purchase multiple delivery machines of different specifications. This not only greatly increases the factory's equipment procurement costs and wastes funds, but also occupies a large amount of production space. At the same time, frequent equipment replacement and debugging reduce production efficiency, thereby squeezing the factory's profit margin and severely restricting the development of the spiral welded pipe production industry.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a delivery machine for spiral welded pipe production, which solves the technical problem in the prior art that it cannot flexibly adapt to the delivery needs of spiral welded pipes of different sizes and can only perform delivery operations for spiral welded pipes of a single size.

[0006] According to one aspect, at least one embodiment of this disclosure provides a delivery machine for spiral welded pipe production, comprising:

[0007] The frame and the horizontal opening, wherein the horizontal opening is formed on the surface of the frame;

[0008] A conveying assembly, which is mounted on the frame;

[0009] The conveying assembly includes a movable seat, which is slidably connected to the horizontal opening. A drive screw is provided in the horizontal opening, and the drive screw is controlled to rotate by a motor. The drive screw and the movable seat are connected by a threaded connection. A pair of rectangular seats are provided on both the movable seat and the surface of the frame.

[0010] As a further technical solution, both the bottom of the movable seat and the bottom of the frame are equipped with telescopic cylinders. The output end of the telescopic cylinder is connected to the base frame. The base frame is equipped with a support plate. The surface of the support plate has a rectangular opening. The base frame is equipped with pulleys.

[0011] As a further technical solution, a pair of movable rods are movably connected inside the rectangular base, and a top frame is connected to the upper end of the movable rods. An outer groove is opened on the side surface of the rectangular base, and a pair of rectangular rods are provided at the bottom of the top frame.

[0012] As a further technical solution, an elongated hole is provided on the surface of the rectangular rod, and a fixing bolt is connected to the outer groove by threaded screwing. The fixing bolt is movably fitted in the elongated hole and pressed against the surface of the rectangular rod. A pressure roller is rotatably connected to the top of the top frame.

[0013] As a further technical solution, one of the top frames is provided with a pair of fixing frames, a second cylinder is mounted on the side surface of the fixing frame, an extension frame is provided at the output end of the second cylinder, and a pair of stabilizing rods are provided on the side surface of the extension frame.

[0014] As a further technical solution, one end of the stabilizing rod is movably fitted inside the fixed frame, a drive motor is installed on the top of the stabilizing rod, and a clamping roller is provided at the output end of the drive motor.

[0015] As a further technical solution, both the pulley and the pressure roller have arc-shaped surfaces, and both have anti-slip surfaces.

[0016] As a further technical solution, an arc-shaped protrusion is provided around the surface of the clamping roller.

[0017] As a further technical solution, the upper end of the pulley is slightly higher than the inner surface of the tray.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the beneficial effect of the conveying assembly is that the cooperation between the drive screw and the moving seat can flexibly adjust the position of the moving seat to adapt to the delivery needs of spiral welded pipes of different diameters, thereby improving the versatility of the equipment. The telescopic cylinder, base frame, pallet and pulley work together to stably support the spiral welded pipe. The arc-shaped anti-slip surface of the pulley fits the welded pipe to ensure stable conveying. The rectangular seat, movable rod, top frame, lower pressure roller and clamping roller and other components can adjust the height and spacing to achieve clamping and conveying of spiral welded pipes of different sizes.

[0032] like Figures 1-4 As shown, a delivery machine for spiral welded pipe production according to an embodiment of the present disclosure includes:

[0033] The frame 1 and the horizontal opening 2 are formed on the surface of the frame 1;

[0034] Conveying component 3 is mounted on frame 1;

[0035] The conveying assembly 3 includes a movable seat 3-1, which is slidably connected within a horizontal opening 2. A drive screw 3-2 is installed within the horizontal opening 2, and the drive screw 3-2 is rotated by a motor. The drive screw 3-2 and the movable seat 3-1 are connected by a threaded connection. A pair of rectangular seats 3-3 are provided on the surface of both the movable seat 3-1 and the frame 1. Telescopic cylinders 3-4 are provided at the bottom of both the movable seat 3-1 and the bottom of the frame 1. The output end of the telescopic cylinder 3-4 is connected to a base frame 3-5. A support plate 3-6 is provided on the base frame 3-5, and a rectangular opening 3-7 is provided on the surface of the support plate 3-6. A pulley 3-8 is installed inside the base frame 3-5. A pair of movable rods 3-9 are movably connected inside the rectangular seats 3-3, and a top frame 3-10 is connected to the upper end of the movable rods 3-9. An outer groove 3-11 is provided on the side surface of the rectangular seats 3-3, and a bottom of the top frame 3-10 is provided with a... For the rectangular rod 3-12, an elongated hole 3-13 is opened on the surface of the rectangular rod 3-12. A fixing bolt 3-14 is screwed into the outer groove 3-11 by thread. The fixing bolt 3-14 is movably fitted in the elongated hole 3-13 and is pressed against the surface of the rectangular rod 3-12. A lower pressure wheel 3-15 is rotatably connected to the top of the top frame 3-10. A pair of fixing frames 3-16 are provided on one of the top frames 3-10. A second cylinder 3-17 is installed on the side surface of the fixing frame 3-16. An extension frame 3-18 is provided at the output end of the second cylinder 3-17. A pair of stabilizing rods 3-19 are provided on the side surface of the extension frame 3-18. One end of the stabilizing rod 3-19 is movably fitted in the fixing frame 3-16. A drive motor 3-20 is installed on the top of the stabilizing rod 3-19. A clamping roller 3-21 is provided at the output end of the drive motor 3-20.

[0036] In some examples, to achieve stable delivery of spiral welded pipes, a conveying assembly 3 is designed. This assembly includes a movable seat 3-1 slidably connected within a horizontal opening 2. A drive screw 3-2, controlled by a motor, is installed within the horizontal opening 2. The drive screw 3-2 and the movable seat 3-1 are threaded together. When the motor drives the drive screw 3-2 to rotate, the movable seat 3-1 moves within the horizontal opening 2. Both the movable seat 3-1 and the frame 1 have a pair of rectangular seats 3-3 on their surfaces, and telescopic cylinders 3-4 are also installed at the bottom. The output end of 3-4 is connected to the base frame 3-5. The support plate 3-6 on the base frame 3-5 supports the spiral welded pipe. A rectangular opening 3-7 is also opened on the surface of the support plate 3-6. A pulley 3-8 is installed inside the base frame 3-5 and located within the rectangular opening 3-7. The pulley 3-8, in conjunction with the support plate 3-6, supports the movement of the spiral steel pipe. A pair of movable rods 3-9 are movably fitted inside the rectangular base 3-3. The upper end of the movable rods 3-9 is connected to the top frame 3-10, which can move vertically up and down. The side surface of the rectangular base 3-3 has an outer groove 3-11. The rectangular rod 3-12 at the bottom of 3-10 has an elongated hole 3-13. A threaded fixing bolt 3-14 is movably fitted into the elongated hole 3-13 within the outer groove 3-11. Tightening the fixing bolt 3-14 presses it against the surface of the rectangular rod 3-12, thus fixing the position of the top frame 3-10. The top of the top frame 3-10 is rotatably connected to a lower pressure roller 3-15, which can cooperate with the pulley 3-8 to press the spiral steel pipe and facilitate conveying. One of the top frames 3-10 is equipped with a pair of fixing brackets 3-16. Fixing bracket 3-1... The second cylinder 3-17 and the extension frame 3-18 are mounted on the side surface of the 6th section. The side surface of the extension frame 3-18 has a pair of stabilizing rods 3-19. One end of the stabilizing rod 3-19 is movably fitted into the fixed frame 3-16. The output end of the drive motor 3-20 mounted on the top is equipped with clamping rollers 3-21. The second cylinder 3-17 can adjust the distance between the two clamping rollers 3-21 by controlling the movement of the extension rods, which can clamp both sides of the spiral pipe. The spiral steel pipe is conveyed and moved by the clamping rollers 3-21 under the control of the drive motor 3-20.

[0037] For example, such as Figure 1 As shown, both pulley 3-8 and pressure roller 3-15 have arc-shaped surfaces, and both surfaces have anti-slip surfaces.

[0038] In some examples, the curved structural surface allows pulleys 3-8 to fit more closely to the surface of the spiral welded pipe, providing more stable support and preventing them from falling off during transport.

[0039] For example, such as Figure 4 As shown, an arc-shaped protrusion 4 is provided around the surface of the clamping roller 3-21.

[0040] In some examples, the use of an arc-shaped protrusion 4 increases the grip on the surface of the spiral welded pipe, preventing slippage.

[0041] For example, such as Figure 4 As shown, the upper end of pulley 3-8 is slightly higher than the inner surface of tray 3-6.

[0042] In some examples, the pulley 3-8 is slightly higher than the support plate 3-6 to prevent the spiral welded pipe from falling out of the support area of ​​the support plate 3-6, and it is also more convenient to put it directly onto the pulley 3-8 during installation.

[0043] In actual use: Place the spiral welded pipe onto the pulley 3-8 in the support plate 3-6, start the telescopic cylinder 3-4 to control the base frame 3-5 to rise, so that the support plate 3-6 and pulley 3-8 clamp the spiral welded pipe with the lower pressure roller 3-15. Then start the second cylinder 3-17 to control the two clamping rollers 3-21 to come into contact and press against both sides of the spiral welded pipe. Then start the drive motor 3-20 to control the clamping rollers 3-21 to rotate and push the steel pipe to move. According to the length of the spiral welded pipe, the drive screw 3-2 can be started to control the moving seat 3-1 to adjust the support position of the spiral welded pipe.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure 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 solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
