The terms "first", "second", and "third" are only used to facilitate the description of the present technical solution and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", and "third" can explicitly or implicitly include one or more of these features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention.

In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0029] The technical solution adopted by the utility model to solve its technical problems is:

[0030] like Figures 1 to 2As shown, some embodiments of the present invention disclose a condenser titanium tube plug sleeve extraction tool, which includes an extraction rod 1, an impact hammer 2 and a screw-in mechanism. The extraction rod 1 is inserted into and fixed in the sleeve of the plug; the extraction rod 1 provides an extraction impact force; the impact hammer 2 is slidably installed on the extraction rod 1; the extraction rod 1 is used to fix the sleeve to the sleeve, and the screw-in mechanism is installed on the extraction rod 1.

[0031] The condenser titanium tube plug sleeve extraction tool is inserted and fixed into the sleeve by an extraction rod 1, and then the impact hammer 2 inertia impacts upward to extract the sleeve, thereby changing the original disassembly method, being simple and convenient to operate, and having high efficiency without damaging the condenser titanium tube.

[0032] In some embodiments, the extraction rod 1 is snap-fitted or interference-fitted with the inner wall of the sleeve, and the impact hammer 2 is used to impact the top of the extraction rod 1, so that the extraction rod 1 has the inertia to move upward.

[0033] The extraction rod 1 includes a handle 11 and a conical head 12; the conical head 12 for fixing to the sleeve is fixedly or detachably mounted on the bottom of the handle 11, or the handle 11 and the conical head 12 are an integral structure.

[0034] In some embodiments, the handle 11 is used to deeply insert the conical head 12 into the sleeve. The deeper the conical head 12 is inserted, the tighter the force with which the conical head 12 is stuck in the sleeve is, thus preventing the conical head 12 from detaching from the sleeve when it is pulled out.

[0035] like Figures 1 to 2 As shown, the conical head 12 is provided with a self-tapping thread 5 .

[0036] In some embodiments, the handle 11 inserts the conical head 12 into the sleeve, and is threadedly connected to the inner wall of the sleeve using the self-tapping thread 5. The conical head 12 and the sleeve engage with each other to prevent the conical head 12 from detaching from the sleeve, preventing the staff from being injured during extraction.

[0037] The thickness of the self-tapping thread 5 provided on the conical head 12 is smaller than the wall thickness of the sleeve.

[0038] In some embodiments, when the self-tapping thread 5 engages with the inner wall of the sleeve, the self-tapping screw will not protrude beyond the thickness of the sleeve wall and damage the sleeve.

[0039] The height of the self-tapping thread 5 is smaller than the depth of the sleeve.

[0040] The length of the tapered head 12 is less than or equal to the depth of the sleeve.

[0041] In some embodiments, when the conical head 12 is completely screwed into the sleeve, it also avoids penetrating the bottom of the sleeve, preventing debris and other foreign matter from entering the titanium tube, thereby protecting the titanium tube.

[0042] The screw-in mechanism comprises a rotating handle 3 for screwing the extraction rod 1 into the sleeve. The rotating handle 3 is fixedly or detachably mounted on the extraction rod 1 .

[0043] In some embodiments, the rotating handle 3 can increase the torque when the extraction rod 1 is screwed in, saving manpower.

[0044] In some embodiments, a slot is provided on the rotating handle 3 , and the extraction rod 1 is inserted into the rotating handle 3 through the slot. When the rotating handle 3 is in a corner or other location where environmental factors do not block the rotation, the rotating handle 3 can be removed.

[0045] The screw-in mechanism further includes a wrench fixing member 4 , which is fixedly or detachably mounted on the upper portion of the extraction rod 1 .

[0046] In some embodiments, after removing the rotating handle 3 , a wrench is clamped on the wrench fixing member 4 to rotate the extraction rod 1 to increase the screw-in torque.

[0047] In some embodiments, the wrench fixing member 4 is a locking nut, and the wrench is clamped onto the locking nut.

[0048] The outer surface of the impact hammer 2 is provided with anti-slip grooves, or the outer surface of the impact hammer 2 is wrapped with a flexible layer.

[0049] In some embodiments, the anti-slip grooves and the flexible layer facilitate workers to prevent slipping and shock when impacting upwards, and facilitate gripping.

[0050] In some embodiments, the flexible layer can be made of some flexible materials such as rubber pads.

[0051] An impact guide mechanism is provided between the impact hammer 2 and the handle 11 .

[0052] The impact guide mechanism includes a protrusion and a groove; the protrusion slides in the groove, the protrusion is arranged on the inner wall of the impact hammer 2, and the groove is opened on the outer wall of the handle 11, or the groove is arranged on the inner wall of the impact hammer 2, and the protrusion is opened on the outer wall of the handle 11.

[0053] In some embodiments, a groove is vertically opened on the side wall of the handle 11, and the protrusion slides vertically along the groove to prevent the impact hammer 2 from rotating, thereby avoiding loss of impact force during impact and preventing injuries to workers caused by rotation during impact.

[0054] The following further describes the pipe inner surface ultrasonic inspection equipment in conjunction with its usage process.

[0055] When the condenser titanium tube plug sleeve extraction tool is used: the extraction rod 1 is rotated by rotating the handle 3, so that the self-tapping thread 5 on the outside of the conical head 12 is screwed into and fixed inside the sleeve, and then the worker holds the impact hammer 2 and strikes upward, using inertia to remove the sleeve from the titanium tube.

[0056] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
