Description

Technical Field

[0001] This utility model relates to the field of pipe joint anchor technology, and in particular to a pipe joint anchor rolling welding device. Background Technology

[0002] The slotted pipe anchor is a new type of anchor that provides full-length anchoring and active reinforcement of the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal slots. When installed in a borehole with a diameter slightly smaller than the pipe diameter, it can immediately apply radial pressure to the borehole wall and frictional force to prevent the surrounding rock from sliding down along its entire length. Combined with the supporting force of the anchor plate, the surrounding rock is placed in a triaxial stress state, achieving rock stratum stability. Under conditions such as blasting vibration and surrounding rock displacement, the anchoring force increases significantly in the later stages. When the surrounding rock undergoes significant displacement, the anchor does not lose its support resistance. It has better characteristics than expansion shell anchors. The slotted pipe anchor mainly consists of a rod body, an anchor plate, and a retaining ring. The retaining ring is fixed to the rod body by welding, and the anchor plate is fitted onto the rod body during use.

[0003] The existing pipe joint anchor bolt retaining ring welding part is welded manually. During welding, the retaining ring and anchor bolt still need to be manually positioned, which is not convenient. In addition, the pipe joint anchor bolt and retaining ring need to be manually rotated one full turn during welding, which brings certain adverse effects to the use process. In order to overcome the shortcomings of the existing technology, we propose a pipe joint anchor bolt roll welding device. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, a pipe joint anchor bolt rolling welding device involves a worker placing the retaining ring to be welded between three sets of movable rods 8 outside the fixed ring 5. The three sets of movable rods 8 limit the retaining ring to be welded. Then, the worker attaches one end of the pipe joint anchor bolt to be welded to one end of the adjusting rod 9. The limiting plate 10 at one end of the adjusting rod 9 is inserted into the gap of the pipe joint anchor bolt to limit the pipe joint anchor bolt and prevent it from rotating freely after being installed on the adjusting rod 9. Next, the pipe joint anchor bolt is continued to be attached to the adjusting rod 9. During this process, one end of the pipe joint anchor bolt passes through the retaining ring to be welded until one end of the pipe joint anchor bolt abuts against one end of the turntable 4. The pipe joint anchor bolt abuts against the outside of one end of the turntable 4 and is inserted into the fixed ring 5. At this time, the fixed ring 5, together with the adjusting rod 9 and the limiting plate 10, limits and fixes one end of the pipe joint anchor bolt and attaches the retaining ring to be welded to the outside of one end of the pipe joint anchor bolt. Then, the worker can use the welding gun 14 on one side of the welding device body 1 to weld the pipe joint anchor bolt and the retaining ring.

[0022] During welding, one end of the pipe seam anchor rod is fixed within the fixing ring 5, while the other end is supported by the support frame 15. Then, the drive motor 2 is started, and the output end of the drive motor 2 drives the transmission wheel 3 to rotate. The rotating transmission wheel 3 drives the turntable 4 to rotate within the main body 1 of the welding device. The rotation of the turntable 4 drives the fixing ring 5 and the adjusting rod 9 to rotate. At the same time, the fixing ring 5 drives the limiting frame 6, the movable rod 8, and the retaining ring to follow the adjusting rod 9, which drives the limiting plate 10, and the pipe seam anchor rod to rotate synchronously. The other end of the pipe seam anchor rod also rotates on the support frame 15. Thus, the worker uses the welding torch 14 to weld the rotating pipe seam anchor rod and the outer side of the retaining ring around one circumference, completing the welding of the pipe seam anchor rod and the retaining ring.

[0023] Example 2, as Figures 2-4 As shown, a pipe joint anchor bolt rolling welding device, by loosening the fastening bolt 7, one end of the fastening bolt 7 no longer abuts against the movable rod 8, and the movable rod 8 is no longer limited by the fastening bolt 7 within the limiting frame 6. Then, the movable rod 8 is pushed through the turntable 4 and slides within the limiting frame 6. The length of the movable rod 8 extending from one end of the fixed ring 5 is adjusted, thereby adjusting the position of the retaining ring installed at one end of the pipe joint anchor bolt. Then, the fastening nut 11 is loosened, and the fastening nut 11 no longer abuts against one end of the turntable 4 to limit the fixing rod 9. The adjusting rod 9 is turned, and the adjusting rod 9 drives the limiting plate 10 to move within the turntable 4 through the thread. The position of the adjusting rod 9 on the turntable 4 is adjusted according to the position of the retaining ring moved by the movable rod 8, thereby opening a groove at one end of the adjusting rod 9 to follow the adjustment position of the corresponding retaining ring. Thus, when the pipe joint anchor bolt and the retaining ring are welded, the groove of the adjusting rod 9 is located at the welding point of the pipe joint anchor bolt and the retaining ring, preventing the adjusting rod 9 from affecting the welding of the pipe joint anchor bolt and the retaining ring.

[0024] After one end of the pipe seam anchor rod is inserted into the fixing ring 5, the first protrusion 12 on the inner wall of the fixing ring 5 abuts against the outer side of one end of the pipe seam anchor rod to increase the resistance of the pipe seam anchor rod in the fixing ring 5 and prevent the pipe seam anchor rod from detaching from the fixing ring 5. At the same time, when the retaining ring is installed between the three sets of movable rods 8 on the outer side of the fixing ring 5, the second protrusion 13 on one side of the movable rod 8 abuts against the outer side of the retaining ring to prevent the retaining ring from detaching from between the movable rods 8. Under the restriction of the first protrusion 12 and the second protrusion 13, the pipe seam anchor rod and the retaining ring are more stable when rotating, thus improving the welding quality.

[0025] It should be noted that this utility model is a pipe seam anchor bolt rolling welding device. In use, the movable rod 8 is used to limit and fix the retaining ring, and the adjusting rod 9 cooperates with the fixing ring 5 to limit and fix one end of the pipe seam anchor bolt, which facilitates the quick installation and positioning of the pipe seam anchor bolt and the retaining ring by the workers. During welding, the welding gun 14 can also be used to weld the pipe seam anchor bolt and the retaining ring, which are driven by the drive motor 2 to drive the transmission wheel 3 to drive the turntable 4 to drive the fixing ring 5 and the adjusting rod 9 to rotate synchronously. There is no need for the workers to move the welding gun 14 to perform circumferential welding on the pipe seam anchor bolt and the retaining ring, making welding more labor-saving.

[0026] When welding different pipe joint anchors and retaining rings, the movable rod 8 can be slid within the limiting frame 6 by loosening the fastening bolt 7. The movable rod 8 supports the movement of the retaining ring, thereby adjusting the welding position of the retaining ring at the end of the pipe joint anchor. This makes the welding operation more operable and convenient for workers. At the same time, the fastening nut 11 can be loosened to move the adjusting rod 9 on the turntable 4. The groove on the adjusting rod 9 corresponds to the welding point of the pipe joint anchor and the retaining ring, preventing the adjusting rod 9 from affecting the welding of the pipe joint anchor and ensuring the welding quality.

[0027] 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 merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
