Technical Field

[0001] This utility model relates to the field of rotating support technology, and in particular to a vertical pipe welding positioning turntable. Background Technology

[0002] The riser welding positioning turntable is a device specifically designed to assist in riser welding operations. Its core function is to achieve precise positioning and rotation of the riser, thereby facilitating welders to perform efficient and high-quality welding work. In actual pipeline engineering, especially in pipeline installation in large-scale construction and chemical industries, the riser welding positioning turntable plays an important role.

[0003] In existing technologies, riser welding positioning turntables generally adopt a fixed weld joint welding method in riser welding operations. The riser is fixed in a specific position and remains stationary. The welder needs to perform welding operations around the stationary steel pipe. In the actual welding process, due to the diversity of welding positions and angles, the welder has to frequently and continuously adjust his position and posture. In the process of frequent adjustment, not only is the continuity of welding operations interrupted, but a lot of time is wasted. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the shortcomings of the existing technology of traditional riser welding positioning turntable, which generally adopts a fixed weld joint welding method in riser welding operations, and the riser is fixed in a specific position and remains stationary. Therefore, a riser welding positioning turntable is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical pipe welding positioning turntable, comprising a base, wherein a rotating device is provided inside the base, the rotating device comprising a bearing, the arc surface of the bearing being fixedly connected to the base, a support ring being fixedly connected to one end of the bearing, the arc surface of the support ring being fixedly connected to the base, a circular tube being fixedly connected to the inner side of the bearing, a through plate being fixedly connected to one end of the circular tube, a placement platform being fixedly connected to one end of the through plate, and an installation groove being provided at one end of the placement platform.

[0006] The effect achieved by the above components is that the platform is subjected to force and rotates, causing the disc to drive the round tube to rotate on the bearing.

[0007] Preferably, one end of the placement platform is provided with a sliding groove.

[0008] The effect achieved by the above components is that the sliding groove is opened on the placement platform.

[0009] Preferably, an arc-shaped plate is slidably connected inside the sliding groove, and one side of the arc-shaped plate is fixedly connected to the base.

[0010] The effect achieved by the above components is that the arc-shaped plate is fixed on the base and assembled on the sliding groove.

[0011] Preferably, the arc surface of the placement platform is fixedly connected with a collar.

[0012] The effect achieved by the above components is to fix the collar on the placement platform.

[0013] Preferably, the arc surface of the collar is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the collar.

[0014] The effect achieved by the above components is that the anti-slip grooves are opened on the collar, increasing the friction of the collar.

[0015] Preferably, the base has a fixing device inside, the fixing device includes a mounting plate, one side of the mounting plate is fixedly connected to the base, and a fixing block is fixedly connected to one side of the mounting plate.

[0016] The effect achieved by the above components is that the fixing block is fixed on the mounting plate, and the mounting plate is fixed on the base.

[0017] Preferably, a rotating rod is rotatably connected inside the fixed block, and a U-shaped plate is fixedly connected to the arc surface of the rotating rod.

[0018] The effect achieved by the above components is that the U-shaped plate moves under force and rotates around the rotating rod, so that the rotating rod rotates on the fixed block.

[0020] The effect achieved by the above components is to fix the frame to the U-shaped plate.

[0021] Preferably, the arc surface of the pull frame is fixedly connected with an anti-slip sleeve, which is made of rubber.

[0022] The effect achieved by the above components is to increase friction by implementing anti-slip sleeves.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, a rotating device is used to smoothly place the riser that fits the mounting groove into the mounting groove when rotational welding is required. Force is applied to the collar by hand, and the collar will drive the placement platform to rotate synchronously, causing the riser in the mounting groove to rotate. The rotating device solves the problem of traditional riser welding positioning turntables, which generally use a fixed weld joint welding method in riser welding operations. The riser is fixed in a specific position and remains stationary, which forces the welder to frequently and continuously adjust their position and posture in order to perform multi-position welding on the riser.

[0025] In this invention, by means of a fixing device, when the turntable needs to be moved, first lift the base to move it away from the placement location, then pull the anti-slip sleeve, which drives the pull frame and U-shaped plate to move, allowing the rotating rod to rotate on the fixing block. After the pull frame is separated from the base, hold the anti-slip sleeve and apply force. The force is transmitted to the base through the fixing block and the mounting plate, completing the movement. By means of a fixing device, the problem of traditional riser welding positioning turntables having fewer external force points, which makes it inconvenient to apply force to the turntable for movement, is solved.

[0031] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a riser welding positioning turntable, including a base 1, a rotating device 2 inside the base 1, and a fixing device 3 inside the base 1.

[0032] The specific configuration and function of its rotating device 2 and fixing device 3 will be described in detail below.

[0033] Reference Figure 2As shown in this embodiment: the rotating device 2 includes a bearing 201, the arc surface of which is fixedly connected to the base 1. A support ring 206 is fixedly connected to one end of the bearing 201, and the arc surface of the support ring 206 is fixedly connected to the base 1. A circular tube 202 is fixedly connected to the inner side of the bearing 201. A disk 203 is fixedly connected to one end of the circular tube 202, and a placement platform 204 is fixedly connected to one end of the disk 203. A mounting groove 205 is provided at one end of the placement platform 204. This achieves the effect that the placement platform 204 rotates under force, causing the disk 203 to drive the circular tube 202 to rotate on the bearing 201. A sliding groove 207 is provided at one end of the placement platform 204. This achieves the effect that the sliding groove 207 is provided on the placement platform 204. An arc-shaped plate 208 is slidably connected inside the sliding groove 207, and one side of the arc-shaped plate 208 is fixedly connected to the base 1. This achieves the effect that the arc-shaped plate 208 is fixed on the base 1 and assembled on the sliding groove 207. A collar 209 is fixedly connected to the arc surface of the placement platform 204. This achieves the effect of fixing the collar 209 to the placement platform 204. Several anti-slip grooves 210 are evenly distributed on the arc surface of the collar 209. This increases the friction of the collar 209.

[0034] Reference Figure 4 As shown, in this embodiment: the fixing device 3 includes a mounting plate 31, one side of which is fixedly connected to the base 1, and a fixing block 32 is fixedly connected to one side of the mounting plate 31. This achieves the effect of fixing the fixing block 32 to the mounting plate 31, and fixing the mounting plate 31 to the base 1. A rotating rod 33 is rotatably connected inside the fixing block 32, and a U-shaped plate 34 is fixedly connected to the arc surface of the rotating rod 33. This achieves the effect of the U-shaped plate 34 rotating around the rotating rod 33 under force, causing the rotating rod 33 to rotate on the fixing block 32. A pull frame 35 is fixedly connected to one side of the U-shaped plate 34. This achieves the effect of fixing the pull frame 35 to the U-shaped plate 34. An anti-slip sleeve 36, made of rubber, is fixedly connected to the arc surface of the pull frame 35. This achieves the effect of increasing friction with the anti-slip sleeve 36.

[0035] Working Principle: Using the rotating device 2, when welding the riser requires rotation, the operator first places the riser conforming to the mounting groove 205 stably within it. The mounting groove 205 can be used for steel risers with diameters from 45 mm to 89 mm. When rotating the riser to complete welding at different positions, the operator must accurately contact the collar 209. The collar 209 has specially designed anti-slip grooves 210 on its surface, which increase the friction between the hand and the collar 209, effectively preventing hand slippage during force application and improving operational safety and stability. Then, according to the welding position requirements, a force is applied evenly and stably in the direction of rotation. This force is transmitted through the hand to the collar 209. Since the collar 209 is mounted on the placement platform 204, it drives the placement platform 204 to rotate synchronously. The placement platform 204, as the support and rotating component of the riser, ensures smooth and stable rotation of the riser within the mounting groove 205 during the rotation process. While the placement platform 204 rotates, the drive plate 203 plays an important transmission role, driving the round tube 202 to rotate on the bearing 201. This provides good support and guidance for the rotation of the round tube 202, reducing resistance and wear during rotation and ensuring the flexibility and stability of rotation. In addition, the sliding groove 207 on the placement platform 204 cooperates with the arc plate 208. The sliding groove 207 slides on the arc plate 208, which plays a role in limiting and guiding. During the rotation of the placement platform 204, the arc plate 208 can effectively prevent the placement platform 204 from shifting position, ensuring that the riser is always on the correct rotation trajectory, improving the accuracy and quality of welding. Through the rotating device 2, the problem of traditional riser welding positioning turntables is solved. In riser welding operations, the welding method of fixed weld joints is generally used. The riser is fixed in a specific position and remains stationary, which forces the welder to frequently and continuously adjust his position and posture in order to perform multi-position welding on the riser.

[0036] With the fixing device 3, when the turntable needs to be moved, the operator first applies force to the base 1, causing the bottom of the base 1 to leave the placement area, and then pulls the anti-slip sleeve 36. The pulling force is transmitted to the pull frame 35, which drives the U-shaped plate 34 to move, causing the rotating rod 33 to rotate on the fixing block 32. After the pull frame 35 is completely separated from the base 1, the operator holds the anti-slip sleeve 36 and continues to apply the pulling force. The pulling force is transmitted to the fixing block 32, and then from the mounting plate 31 to the base 1, thus completing the movement of the turntable. With the fixing device 3, the problem of traditional riser welding positioning turntables having fewer external force points, making it inconvenient to apply force to the turntable for movement, is solved.
