[0002] The inner liner pipe butt welding device connects the inner liner pipe with the outer shell pipe and uses an appropriate welding method to ensure a reliable seal and connection between the inner liner pipe and the outer shell pipe. However, the existing inner liner pipe butt welding device usually uses a protective sleeve with a fixed mechanism to butt the inner liner pipe and the outer shell pipe, which makes it impossible for the staff to adjust the angle of the protective sleeve. When the inner liner pipe and the outer shell pipe are butt-jointed, the size of the inner liner pipe and the outer shell pipe is also limited, thereby reducing its practicality in actual use. Therefore, we provide an inner liner pipe butt welding device with a fixed structure. Utility Model Content

[0023] In the present embodiment, when the staff uses the inner liner pipe butt welding device to perform inner liner pipe butt welding, the staff rotates the protective sleeve 14 so that the first connecting seat 13 can be adjusted in the damping rotation in the first base frame 11 under the action of the first damping adjuster 12 until the protective sleeve 14 is rotated to be aligned with the top ring 19 and the bottom ring 16. Then the staff only needs to adjust the position of the top ring 19 on the adjusting rod 18 by threaded rotation, and limit the top ring 19 by using the spring 110 to prevent the top ring 19 from being too high and causing damage to the top ring 19, thereby improving the practicality of the inner liner pipe butt welding device in actual use.

[0024] Example 2

[0025] like Figure 1-4 As shown, a fixing mechanism 3 is provided at the joint of the bending mechanism 2 and the sleeve mechanism 1, and the fixing mechanism 3 includes a flat pad 32. A right-angle pad 31 is provided at the joint of the two first base frames 11, and one side of the right-angle pad 31 and the flat pad 32 are in contact with the first base frame 11 and the second base frame 21. The fixing screw 33 passes through the right-angle pad 31 and the flat pad 32 and is fixed to the first base frame 11 and the second base frame 21 by threaded rotation.

[0026] In the present embodiment, when the staff uses the inner liner pipe butt welding device to perform inner liner pipe butt welding, they use the right-angle pad 32 and the flat-angle pad 31 to contact the casing mechanism 1 and the bending mechanism 2, and then use the fixing screw 33 to pass through the right-angle pad 31 and the flat-angle pad 32 and fix them on the first base frame 11 and the second base frame 21 by threaded rotation, thereby preventing the casing mechanism 1 and the bending mechanism 2 from shifting during the inner liner pipe butt welding, thereby further improving the practicality of the present invention in actual use.

[0027] Working principle:

[0028] like Figure 1-4 As shown, when the worker uses the liner pipe butt welding device to perform liner pipe butt welding, the following design scheme can be adopted. First, by rotating the protective sleeve 14, the first connecting seat 13 can be adjusted in damping rotation in the first base frame 11 under the action of the first damping adjuster 12 until the protective sleeve 14 is rotated to align with the top ring 19 and the bottom ring 16. In this way, the correct position and angle can be ensured for the butt welding operation.

[0029] In order to avoid the problem that the top ring 19 is too high and may cause injury, the staff only needs to adjust the position of the top ring 19 on the adjustment rod 18 by screwing, and use the spring 110 to limit the top ring 19. This can prevent the top ring 19 from being too high, thereby protecting the safety of the welding operation.

[0030] In addition, when the inner liner butt welding device is used for butt welding, the right-angle pad 32 and the flat-angle pad 31 can be used to contact the casing mechanism 1 and the pipe bending mechanism 2. Then, the right-angle pad 31 and the flat-angle pad 32 are passed through and fixed on the first base frame 11 and the second base frame 21 by fixing screws 33 to prevent the casing mechanism 1 and the pipe bending mechanism 2 from shifting during the inner liner butt welding process. In this way, the accuracy and stability of welding can be ensured.

[0031] These improved designs and operating steps help to improve the efficiency and safety of the liner pipe butt welding device. They ensure the correct position and angle for butt welding operations and prevent injuries that may be caused by the top ring 19 being too high. At the same time, the use of right-angle pads 31 and flat-angle pads 32 to fix the casing mechanism 1 and the bending mechanism 2 can avoid the problem of displacement during the butt welding process and ensure the accuracy and reliability of welding.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
