Technical Field

[0001] The utility model relates to the technical field of metal pipe welding platforms, in particular to a metal pipe welding platform which is easy to move. Background Art

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipes. Construction projects, power plants, chemical plants, etc. often use such pipes. The welding of existing metal pipes requires circumferential welding, but the existing welding platforms that can fix pipes are generally large in size and inconvenient to carry. They are not suitable for some on-site welding processing situations. In addition, some small devices that can fix pipes can fix pipes, but it is difficult to align the two sets of pipes with each other, so that during the welding process, the welding may be skewed, resulting in poor quality of the finished product after welding. For this reason, we propose a mobile metal pipe welding platform to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides an embodiment: a metal pipe welding platform that is easy to move, including a mounting base 1, a fixed ring 2 is fixedly installed on the upper end of the mounting base 1, a movable ring 3 is movably installed on one side of the fixed ring 2, three groups of limiting grooves 5 are opened on the movable ring 3, a support rod 4 is movably installed in the limiting groove 5, an arc plate 6 is fixedly installed on the upper end of the support rod 4, an opening mechanism is provided in the movable ring 3, and a supporting mechanism is provided on the mounting base 1. The device is small in size and easy to carry, and can adapt to some on-site processing situations. In addition, a supporting mechanism is provided to provide additional support for the pipe, which increases the stability of the device when in use;

[0021] Furthermore, the opening mechanism includes a fixed block 7, which is arranged at the center of the movable ring 3. Three groups of hinged rods 10 are hinged on the fixed block 7, and a support rod 4 is hinged on the hinged rod 10. A screw sleeve 8 is fixedly installed at the center of the fixed block 7, and a screw rod 9 is rotatably installed on the fixed ring 2. The screw sleeve 8 is connected to the screw rod 9 through a thread. A first guide rod 13 is arranged in an array on the movable ring 3, and a first guide hole 14 is opened in an array on the fixed ring 2. The first guide rod 13 is inserted in the first guide hole 14 and moves. This structure uses the mechanism of rotating the screw rod 9 to extend the length of the support rod 4, so that the inner wall of the pipe can be fixed. This method can not only fix the pipe, but also has the function of making the pipe level and adapting to different pipe sizes.

[0022] Furthermore, the distance from the edge plane of the fixing block 7 to the center of the fixing block 7 is equal, and the length of the screw 9 is greater than the length of the hinged rod 10. This structure allows the fixing block 7 to have sufficient stability when subjected to force, and will not cause one side to be dented or damaged during long-term use. In addition, the longer length of the screw 9 can ensure that the support rod 4 can be recovered to the greatest extent.

[0023] Furthermore, a damping rubber pad 11 is fixedly installed on the upper side of the arc plate 6, and an array of deformation holes 12 are opened on the damping rubber pad 11. This structure allows the opening mechanism to fit more closely with the inner wall of the pipe during use, and at the same time can reduce the damage to the pipe itself caused by squeezing.

[0024] Furthermore, a limit block 15 is fixedly installed on the right end of the screw rod 9, and a disc handle 16 is fixedly installed on the left end of the screw rod 9. This structure makes it easier for the screw rod 9 to rotate, and at the same time prevents the movable ring 3 from separating from the mounting base 1.

[0025] Furthermore, the supporting mechanism includes a mounting block 17, which is fixedly mounted on the mounting base 1, and a supporting block 18 is rotatably mounted on the mounting block 17. A turning handle 19 is fixedly mounted on the rotating shaft of the supporting block 18, and a sleeve 20 is fixedly mounted at the end of the turning handle 19. A movable rod 21 is movably inserted into the sleeve 20, and an insertion hole 22 is opened in a ring array on the front side of the mounting base 1, and the movable rod 21 is inserted into the insertion hole 22. This structure allows the support block 18 to be rotated.

[0026] Furthermore, a damping rubber block 23 is fixedly installed at the end of the support block 18, and the end of the damping rubber block 23 is rounded. This structure makes the device more adaptable to the shape of the pipe and at the same time makes the device more capable of supporting the pipe.

[0027] Furthermore, a second guide hole 24 is provided on the mounting base 1, and a second guide rod 25 is movably inserted into the second guide hole 24. This structure allows the two sets of mounting bases 1 to be easily aligned, thereby increasing the convenience of using the device.

[0028] Working principle: When in use, insert the movable ring 3 into the pipe, then rotate the disc handle 16 to make the screw 9 rotate through the threaded action between the screw sleeve 8 to make the hinged rod 10 gradually vertical, so that the support rod 4 opens synchronously so that the damping rubber pad 11 squeezes the inner wall of the pipe to achieve stability of the pipe, then rotate the handle 19 to make the support block 18 rotate so that the damping rubber block 23 presses against the lower side of the pipe for support, then insert the movable rod 21 into the insertion hole 22 for fixing, then fix another group of pipes that need to be welded on another group of mounting bases 1, then insert the second guide rod 25 into the second guide hole 24 so that the two groups of mounting bases 1 are aligned, so that the pipes are in contact and can be welded. The above is the entire working principle of the utility model.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
