DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-3, A device for removing scale from the pipe port, comprising a cylinder body 1 and a tail cover 2. The outer edge of the tail cover 2 is fixed to one end of the cylinder body 1 by bolts. The other end of the cylinder body 1 is open for inserting the pipe. An electric motor chuck 3 is installed outside the tail cover 2, and a reverse-threaded screw rod 10 is to be installed on the electric motor chuck 3. There is a through hole at the tail cover 2, and the through hole is connected to the electric motor chuck 3 by a reinforced metal glue. In this way, when the electric motor chuck 3 rotates, the tail cover 2 also rotates. The electric motor chuck 3 can be driven to rotate by an external device, and the external device can be an electric drill. Just insert the electric motor chuck 3 into the drill bit. The electric drill drives the electric motor chuck 3 to rotate, and also drives the tail cover 2 and the cylinder body 1 to rotate. Since the pipe is inserted through the opening of the cylinder body 1, the cylinder body 1 can rotate around the pipe.
[0020] After the cylinder body 1 rotates, scale removal needs to be achieved. A strip-shaped groove 4 is provided on the outer wall of the cylinder body 1. The strip-shaped groove 4 is arranged along the axial direction of the cylinder body 1. A scale scraping mechanism is arranged in the strip-shaped groove 4. The scale scraping mechanism includes a knife handle 5. An activity seat 6 with an integral structure is arranged in the middle of the knife handle 5. There is a round hole at the activity seat 6, and a cylindrical pin 7 passes through the pipe in the round hole. Both ends of the cylindrical pin 7 are fixedly arranged on the wall of the cylinder body 1. There is a gap between the knife handle 5 on both sides of the activity seat 6 and the bottom of the strip-shaped groove 4. A spring 8 is arranged behind the knife handle, and a knife head 9 is arranged in front of the knife handle 5. Since the cylinder body 1 is driven by an electric method, the rotation speed of the cylinder body 1 is relatively fast. If the position of the knife head 9 is fixed, the knife head 9 may be damaged. Moreover, after the pipe is inserted into the cylinder body 1, if the knife head 9 is fixed, the scale removal operation cannot be achieved. If the scale removal operation is to be achieved, the knife head 9 will limit the pipe, and the pipe cannot be inserted. Therefore, by arranging the activity seat 6, the knife handle 5 can swing back and forth, and then the knife head 9 can swing slightly. The elastic potential energy of the spring 8 can make the knife head 9 act on the pipe for scale removal.
[0021] The rotation of the cylinder body 1 can only remove the scale around the axis of the position of the knife head 9 for one circle. Then, as long as the cylinder body 1 moves, the knife head 9 can also move accordingly to achieve the scale removal operation for a section of the pipe. Therefore, a reverse-threaded screw rod 10 is arranged on the electric motor chuck 3. The reverse-threaded screw rod 10 extends into the cylinder body 1. A top block 11 is installed on the reverse-threaded screw rod 10 in the cylinder body 1. There is a gap between the top block 11 and the inner wall of the cylinder body 1. After the pipe enters the cylinder body 1, and the top block 11 acts on the end face of the pipe. The threaded hole of the top block 11 is threadedly connected to the reverse-threaded screw rod 10. After the electric drive is started, the reverse-threaded screw rod 10 also rotates. The operator needs to have a thrust towards the pipe direction. Then the top block 11 will move and rise on the reverse-threaded screw rod 10, and the cylinder body 1 will retreat along with the pipe to achieve the scale removal operation at the pipe port.
[0022] There are two grooves on the inner wall of the cylinder body 1. The head ends of the grooves are arranged on the end face of the cylinder body 1. The grooves are also of strip structure. A roller 12 is inserted into the grooves. The grooves limit the roller 12 radially. The roller 12 can contact the outer wall of the pipe. A threaded hole is arranged on the end face of the cylinder body 1 beside the head end of the groove. A gasket bolt 13 for limiting the roller 12 is connected at the threaded hole. The gasket bolt 13 limits the roller 12 axially. Therefore, the roller 12 can roll in the grooves. The two grooves and the strip-shaped groove are arranged equidistantly on the cylinder body 1. This structural arrangement makes the rotation of the cylinder body 1 around the pipe more stable.
[0023] Since the roller 12 can contact the pipe, the gap left between the top block 11 and the inner wall of the cylinder body 1 should be greater than the thickness of the part of the roller 12 exposed outside the inner wall of the cylinder body 1, so that the roller 12 will not limit the top block 11.
[0024] A groove part is arranged at the rear of the knife handle 5. One end of a spring 8 is connected to the groove part 5. The other end of the spring 8 acts on the bottom of the strip-shaped groove 4. The arrangement of this groove part can limit the position of the spring 8 and prevent the spring 8 from displacing, which affects the acting force on the cutter head 9. In order to better the cutter head 9, a guard blade 14 is installed at the front end of the knife handle 5. After the cutter head 9 peels the pipe, the skin of the pipe needs to be discharged. Therefore, a discharge port 15 is opened on the end face of the cylinder body 1. The position of the discharge port 15 corresponds to the position of the cutter head 9.
[0025] A thread sheath 16 is also installed on the reverse-threaded lead screw 10. The thread sheath 16 is fixedly connected to the top block 11. The thread sheath 16 can not only protect the reverse-threaded lead screw 10, but after the peeling operation is completed, the thread sheath 16 can be rotated down. It is rather troublesome to rotate the top block 11. In this way, the next pipe peeling operation can be carried out.
[0026] Working principle: When in use, it is necessary to press the position of the knife handle 5 corresponding to the spring 8 to lift the cutter head 9. After the cylinder body 1 is inserted into the pipe, connect the electric drill bit to the motor chuck 3, and the user needs to have a thrust force towards the inner pipe. After the electric drill is started, the cylinder body 1 rotates, and the cutter head 9 starts to peel the pipe. The top block 11 and the thread sheath 16 move upward as the reverse-threaded lead screw 10 rotates, and the cylinder body 1 also starts to gradually withdraw from the pipe until the peeling operation at the pipe port is completed.
[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
