Description

Technical Field

[0001] The utility model relates to the technical field of burr removal, in particular to a burr removal device for a fire-fighting steel pipe mouth. Background Art

[0002] Firefighting pipes refer to pipe materials used in firefighting to connect firefighting equipment and instruments and to transport firefighting water, gas or other media. Due to special needs, the thickness and material of firefighting pipes have special requirements, and they are sprayed with red paint to transport firefighting water. In the process of producing firefighting steel pipes, burrs are prone to appear at the pipe mouths of firefighting steel pipes. The main method of removing burrs is mainly through manual grinding. The accuracy of manual grinding is not easy to master, and it is easy to have uneven grinding, uneven depth, and grinding with gaps. For example, the patent with publication number CN215903271U discloses a firefighting steel pipe pipe mouth burr removal device, including a fixed rod, the top of the fixed rod is fixedly connected to a grinding motor, the output end of the grinding motor is fixedly connected to a grinding wheel, the lower surface of the fixed rod is provided with a storage groove, the inner wall of the storage groove is slidably connected to an adjusting rod, the side of the adjusting rod is connected to a rolling wheel through a rotating shaft, the lower surface of the adjusting rod is provided with a fixed groove, and the inner wall of the fixed groove is slidably connected to a pull rod. The device uses a rolling wheel, a pull rod, a fixed block, a fixed wheel and a fixed spring to make the rolling wheel and the fixed wheel close to the inner wall and outer wall of the fire-fighting steel pipe mouth. The fixing rod, the adjusting rod and the fixing bolt can be used to adjust the distance between the grinding wheel and the rolling wheel according to the diameter of the fire-fighting steel pipe mouth, so that the grinding wheel is close to the inner wall of the fire-fighting steel pipe mouth.

A first fixing bolt 503 is installed between the first telescopic rod 4 and the mounting head 501 . The first fixing bolt 503 corresponds to the first through slot 502 .

[0024] Specifically, the mounting head 501 and the first telescopic rod 4 can be fixed by the first fixing bolt 503, and the mounting angle of the mounting head 501 can be changed according to needs. When the motor 1 is held in the hand, after the mounting head 501 is fixed to the first telescopic rod 4, the grinding assembly 6 grinds the pipe mouth of the fire-fighting steel pipe from the outside. When the motor 1 is fixed in the pipe mouth of the fire-fighting steel pipe, the mounting head 501 is rotated 180° and fixed, and the pipe mouth of the fire-fighting steel pipe can be ground.

[0030] When you can choose to use sandpaper 604 to grind the mouth of the fire-fighting steel pipe, when preparing, put the sandpaper 604 inside the mounting frame 602, and then fix the sandpaper 604 and the mounting frame 602 through the second fixing bolt 605, and then use the sandpaper to grind the mouth of the fire-fighting steel pipe.

[0031] The fixing assembly 7 includes a plurality of mounting plates 702 and a plurality of clamping plates 703 . A second telescopic rod 701 is fixed between the mounting plates 702 and the clamping plates 703 . The mounting plates 702 are fixed to the peripheral side of the motor 1 by bolts.

[0032] Specifically, when the motor 1 needs to be installed in the pipe mouth of the fire-fighting steel pipe, the motor 1 is placed in the pipe mouth of the fire-fighting steel pipe, and then the second telescopic rod 701 is manually stretched so that the clamping plate 703 contacts the inner wall of the fire-fighting steel pipe. After the length of the second telescopic rod 701 is fixed, the motor 1 can be clamped and fixed inside the fire-fighting steel pipe, thereby eliminating the need to hold the motor 1 by hand and ensuring the grinding effect.
