[0029] The following description of the embodiments of the present invention is further described in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present invention clearer and more specific. The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present invention, but should not be construed as limiting the present invention.

[0030] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention.

[0031] Reference Figure 1 As shown, a circular tube annular seam grinding device includes a protective frame 1, a work object support and transportation mechanism 2 and a grinding mechanism 3. The protective frame 1 is a hollow frame that passes through the front and back. The work object support and transportation mechanism 2 is inserted into the protective frame 1 and is used to support and transport the work object 4 into the protective frame 1 for grinding. The grinding mechanism 3 is installed in the protective frame 1 and is used to grind the work object 4.

[0032] Reference Figure 2As shown, the protective frame 1 is preferably an integrally formed square plate-shaped frame, with the top and left and right sides of the square plate-shaped frame forming closed protective baffles. The grinding mechanism 3 includes three grinding units, each mounted on the top and left and right sides of the square frame. The bottom of the square plate-shaped frame is provided with a through-cut notch to facilitate assembly with the work object support and transport mechanism 2. Obviously, those skilled in the art may select other protective frame shapes, currently known or to be realized in the future, according to actual needs, as long as they can serve the purpose of mounting the grinding mechanism and providing protection during grinding.

[0033] Reference Figure 3 As shown, the work object support and transportation mechanism 2 includes a track 2-1, a roller 2-2 and a hub frame 2-3. The track 2-1 is inserted into the protective frame 1, and the hub frame 2-3 is used to carry the work object 4 and is moved and installed on the track 2-1 through the roller 2-2; when working, the work object such as the welded round pipe to be polished is transported to the protective frame 1 for polishing through the moving hub frame 2-3, and the polished work object is output.

[0034] In this embodiment, the track 2-1 is preferably a bar track made of angle steel, which is strong and easy to process. The roller 2-2 is preferably a concave wheel that cooperates with the angle steel. Obviously, those skilled in the art may adopt other existing or future structural forms of tracks and rollers according to different actual needs, as long as they are strong enough to support the hub frame and the corresponding operation.

[0035] In this embodiment, the hub carrier 2-3 includes a base 2-3-1 and a support wheel 2-3-2 rotatably mounted on the base 2-3-1. During operation, the rotation of the support wheel 2-3-2 causes the welded circular pipe to rotate, thereby achieving comprehensive grinding of the circular pipe's circumferential seam. It should be noted that the rotatable mounting and rotational drive method of the support wheel 2-3-2 on the base 2-3-1 are common technical knowledge known to those skilled in the art and will not be further described here. For example, a motor can be used to drive the rotation of the support wheel 2-3-2, and a tank chain can be used to power the motor.

[0036] Reference Figure 4 As shown, the grinding mechanism 3 includes a universal rotating head 3-1, a telescopic rod 3-2, a motor 3-3 and a grinding disc 3-4. The fixed end of the telescopic rod 3-2 is mounted on the protective frame 1 through the universal rotating head 3-1 to form an angle-adjustable structure. The motor 3-3 is installed at the telescopic end of the telescopic rod 3-2, and the grinding disc 3-4 is connected to the rotating shaft of the motor 3-3.

[0037] During operation, the telescopic direction of the telescopic rod 3-2 is adjusted by the universal rotating head 3-1, and the telescopic length of the telescopic rod 3-2 is used to match the working objects 4 of different specifications, effectively improving the operation corresponding versatility of the grinding device and ensuring the grinding accuracy.

[0038] It should be noted that the specific structure of the universal rotating head 3-1 is conventional, comprising a grooved base, a shaft head rotatably mounted within the groove, and a locking mechanism for locking the shaft head after adjusting its orientation. The telescopic rod 3-2 is a conventionally known telescopic cylinder or hydraulic cylinder. The configuration of the drive circuitry for the telescopic cylinder or hydraulic cylinder and the power supply circuitry for the motor are common knowledge within the skill of those skilled in the art and will not be elaborated upon here.

[0039] It should be noted that the grinding disc 3-4 is detachably connected to the rotating shaft of the motor 3-3. In actual application, different grinding discs can be replaced according to different grinding requirements. As for the specific detachable connection method, it is common technical knowledge mastered by those skilled in the art, such as a detachable pin connection, etc.

[0040] It should be noted that, in some embodiments, the universal rotating head 3 - 1 may be omitted, and the telescopic rod 3 - 2 may be replaced by a connecting rod of fixed length, which is not limited to this embodiment.

[0041] The present embodiment provides a circular tube annular seam grinding device, whose working process includes the following steps: 1) connecting the corresponding grinding disc 3-4 to the rotating shaft of the motor 3-3 as needed; 2) placing the work object 4 to be ground on the hub frame 2-3; 3) pushing the hub frame 2-3 and the work object 4 to be ground into the protective frame 1 together, and making the weld of the work object 4 roughly correspond to the grinding mechanism 3; 4) adjusting the grinding mechanism 3 so that the grinding disc 3-4 fits the weld to be ground; 5) starting the grinding disc 3-4 and starting the supporting wheel 2-3-2 to make the work object 4 rotate, so as to achieve comprehensive grinding of the weld on the work object 4, and 6) withdrawing the hub frame 2-3 and the ground work object 4 from the protective frame 1 together.

[0042] It should be noted that the wheel hub 2 - 3 may be moved in and out of the protection frame 1 manually, or may be driven electrically or pneumatically, which are conventional technical means known to those skilled in the art.
