Description

Technical Field

[0001] This utility model relates to the field of steel structure manufacturing technology, specifically to an adjustable limiting device for manufacturing steel pipes with stiffening rings. Background Technology

[0002] Stiffening ring steel pipes are commonly used in buried water pipelines, oil pipelines, and gas pipelines. Stiffening rings are installed on the outer wall of the pipeline to reinforce it. Welding and corrosion protection of these pipes require the use of roller frames. However, axial displacement of the steel pipe during roller frame rotation causes difficulties in welding and corrosion protection, affecting construction quality. This patent addresses this issue by incorporating an adjustable limiting device between a set of rollers. This device can accommodate various specifications of steel pipes (with inconsistent pipe lengths and varying stiffening ring positions) and ensures consistent quality during pipe section welding and corrosion protection.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] Example 1

[0030] like Figure 1 As shown, an adjustable limiting device for manufacturing steel pipes with stiffening rings includes a base plate 1 mounted on a rolling frame, and a limiting frame 2 mounted on the base plate 1; two movable limiting mechanisms 3 for slidingly clamping the steel pipe reinforcing ribs are slidably arranged on the limiting frame 2, and a driving mechanism for driving the movable limiting mechanisms 3 to slide along the limiting frame 2 is also provided on the limiting frame 2.

[0031] The limiting frame 2 is equipped with a connector for fixed connection with the base plate 1. The base plate 1 has an elongated hole corresponding to the position of the connector to facilitate the adjustment and fixing of the limiting frame 2. The connector includes a bolt. The bolt passes through the elongated hole on the limiting frame 2 and the base plate 1 to fix the limiting frame 2 to the base plate 1. Since the fixing position of the bolt and the base plate 1 is in the elongated hole, the installation position can be adjusted in the elongated hole. If a large position adjustment is needed, it can be fixed in the elongated hole at a suitable position.

[0032] The movable limiting mechanism 3 includes a sliding plate 31 that slides on the limiting frame 2. The limiting frame 2 is equipped with a slide rail, and the limiting frame 2 has a slide groove corresponding to the slide rail. The slide rail slides relative to the limiting frame 2 in the slide groove. The driving mechanism pushes the sliding plate 31 to move. A wheel axle 32 is fixedly installed on the sliding plate 31, and a rotating wheel 33 is installed on the wheel axle 32 through a bearing.

[0033] The drive mechanism includes a lead screw 5, which has two threads in opposite directions. Two movable limit mechanisms 3 are respectively connected to the two threads of the lead screw 5. The lead screw 5 is mounted on the limit frame 2 through a bearing seat. The sliding plate 31 is threadedly connected to the lead screw 5. One end of the lead screw 5 extends out of the limit frame 2 and is fixedly mounted with a handle wheel 6.

[0034] In use, first connect the base plate 1 to the roller frame to ensure that it can move synchronously with the roller frame. Confirm the installation position of the limit frame 2 on the base plate 1 by the steel pipe model and specifications. Rotate the screw 5, which will push the two movable limit mechanisms 3 to separate. After placing the steel pipe stiffening ring between the two movable limit mechanisms 3, rotate the handle wheel 6 at one end of the screw 5. Use the screw 5 to push the two movable limit mechanisms 3 closer to the middle stiffening ring until the gap between the two movable limit mechanisms 3 is less than 20mm. Then stop rotating the handle wheel 6 and start the roller frame to drive the steel pipe to rotate.

[0035] Example 2

[0036] like Figures 1-2 As shown, the difference between this embodiment and embodiment 1 is that: it also includes a fixed limiting device, which is welded to one end of the slide rail of the limiting frame 2, and the number of movable limiting mechanisms 3 in embodiment 1 is 1, and the threads of the lead screw 5 are all in the same direction; the fixed limiting mechanism 4 and the movable limiting mechanism 3 have the same structure and are installed in opposite directions; it is easier to operate by fixing on one side and clamping the reinforcing rib on the other side, which avoids the situation where when the two movable limiting mechanisms 3 clamp the reinforcing ring in the middle, the reinforcing ring is not in the middle position of the two movable limiting mechanisms 3, causing one movable limiting mechanism 3 to continue to advance after getting close to the reinforcing ring, while at the same time the other movable limiting mechanism 3 is still far away from the reinforcing ring, which may damage the rotating wheel 33 or the reinforcing ring.

[0037] In use, first connect the base plate 1 to the roller frame to ensure that it can move synchronously with the roller frame. Confirm the installation position of the limit frame 2 on the base plate 1 according to the steel pipe model and specifications. Rotate the screw 5, which will push the two movable limit mechanisms 3 to separate. Place the steel pipe stiffening ring between the movable limit mechanism 3 and the fixed limit mechanism 4, ensuring that the rotating wheel 33 of the fixed limit mechanism 4 is in contact with the steel pipe reinforcing rib. Rotate the handle wheel 6 at one end of the screw 5, and use the screw 5 to push the movable limit mechanism 3 closer to the fixed limit mechanism 4 until the gap between the movable limit mechanism 3 and the fixed limit mechanism 4 is less than 20mm. Then stop rotating the handle wheel 6 and start the roller frame to drive the steel pipe to rotate.

[0038] Example 3

[0039] The difference between this embodiment and embodiment 1 is that: one end of the lead screw 5 extends out to the limit frame 2 and connects to an external motor; a motor-driven method is used to replace manual rotation of the lead screw 5 to adjust the position of the limit mechanism, which improves safety and makes it more convenient to use.

[0040] In use, first connect the base plate 1 to the roller frame to ensure that it can move synchronously with the roller frame. Confirm the position of the limit frame 2 on the base plate 1 by the steel pipe model and specifications. Rotate the screw 5, which will push the two movable limit mechanisms 3 to separate. After placing the steel pipe stiffening ring between the two movable limit mechanisms 3, start the external motor to drive the screw 5 to rotate. Use the screw 5 to push the two movable limit mechanisms 3 closer to the middle stiffening ring until the gap between the two movable limit mechanisms 3 is less than 20mm. Then stop rotating the handle wheel 6 and start the roller frame to drive the steel pipe to rotate.

[0041] The aforementioned roller frame is existing technology and will not be described in detail here.

[0042] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
