DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] Example

[0040] like Figure 1-4 As shown, this embodiment provides a technical solution: an oil spraying and rust removal mechanism for the outer surface of a construction pipe, comprising a mounting seat 5 with a through hole 9 for the pipe to pass freely, the inner diameter of the through hole 9 is slightly larger than the outer diameter of the pipe to be rust-removed, a bearing is embedded on the mounting seat 5, a rotating sleeve 3 is coaxially and rotatably mounted in the bearing, the inner hole of the rotating sleeve 3 exposed at one end of the mounting seat 5 is provided with bristles, and a grip 6 is integrally formed on the outer edge of the mounting seat 5. When rust removal is performed on the pipe, one end of the pipe can be first fixed on an external fixture, or the staff can hold the pipe, and then the unfixed end of the pipe is inserted into the through hole 9, and then passed out from the inner hole of the rotating sleeve 3. Through the rotation of the rotating sleeve 3, the bristles on the inner hole of the rotating sleeve 3 clean the rusted parts on the outer surface of the pipe, so that the parts of the outer wall of the pipe with a small degree of rust can be rust-removed;

[0041] Please refer to Figure 1 , 2 4. Since the rotating sleeve 3 needs to rotate at a high speed, the bristles on the inner hole of the rotating sleeve increase the friction force on the outer wall of the pipe to achieve rust removal on the surface of the pipe. Therefore, in this embodiment, a motor mounting seat 1 is welded on the mounting seat 5, and a mounting cavity is opened at one end of the motor mounting seat 1. The mounting cavity is in the form of a blind hole, and a motor 8 is installed in the mounting cavity by screws. The rotating shaft of the motor 8 can rotatably pass through the motor mounting seat 1. In addition, a driving gear 2 is fixedly sleeved on one end of the rotating shaft of the motor 8 passing through the motor mounting seat 1, and a driven gear 4 is fixedly sleeved on the end of the rotating sleeve 3 exposed from the mounting seat 5. The driving gear 2 is externally meshed with the driven gear 4. In this way, when the external power supply supplies power to the motor 8, the rotating shaft of the motor 8 rotates and drives the driving gear 2 to rotate, and then the driving gear 2 and the driven gear 4 are meshed and rotated, thereby driving the rotating sleeve 3 to rotate, so that the bristles on the rotating sleeve 3 can generate friction on the outer wall of the pipe, thereby achieving rust removal of the rusted parts on the outer surface of the pipe;

[0042] Please refer to Figure 2 , 3Since the rusted parts on the outer wall of the pipe are severely rusted, especially after rust residue is generated, the friction force of the brush bristles on the rusted parts alone cannot effectively remove the rusted parts. Therefore, in this embodiment, a liquid storage chamber 12 for storing liquid rust remover is opened in the handle 6, and a plurality of capillary inlet holes 19 that are interlinked with the liquid storage chamber 12 are opened on the hole wall of the through hole 9. A piston 10 that forms a sliding fit with the liquid storage chamber 12 is provided in the liquid storage chamber 12. The piston 10 and the inside of the liquid storage chamber 12 are separated into an air storage chamber 13 for storing compressed air. A floating pin 17 is vertically slidably penetrated in the mounting seat 5. The two ends of the floating pin 17 are respectively penetrated into the through hole 9 and the liquid storage chamber 12. A sealing plug 16 is coaxially fixedly connected to one end of the floating pin 17 that penetrates into the liquid storage chamber 12. The positive projection area of ​​the sealing plug 16 can cover multiple capillary inlets. The compressed air in the liquid hole 19 and the air storage chamber 13 generates an extrusion force on the piston 10, so that the piston 10 can generate an extrusion force on the liquid rust remover in the liquid storage chamber 12. When the end of the pipe penetrates into the perforation, the end of the floating pin will be pushed by the pipe, so that the floating pin slides toward the inner side of the liquid storage chamber 12, so that the sealing plug 16 is separated from the state of abutment with the inner wall of the liquid storage chamber 12. At this time, the liquid rust remover in the liquid storage chamber 12 can be quickly sprayed into the perforation 9 through multiple capillary liquid inlet holes 19, and then the liquid rust remover can be splashed onto the outer surface of the pipe. In this way, the chemical rust removal of the rusted parts by the liquid rust remover can effectively remove the rust residue, and then the mounting seat 5 is moved so that the end of the pipe can enter the inner hole of the rotating sleeve 3, and then the outer surface of the pipe can be rust-free by the bristles through the rotation of the rotating sleeve;

[0043] Please refer to Figure 2 , 3 , because when the pipe is separated from the perforation 9, the floating pin needs to move toward the perforation direction and make the end face of the sealing plug abut against the inner wall of the liquid storage chamber to prevent the liquid rust remover in the liquid storage chamber from continuing to enter the perforation, therefore, in this embodiment, a hollow frame 14 is fixed on the inner wall of the liquid storage chamber 12, and the sealing plug 16 is arranged between the hollow frame 14 and the floating pin 17, and a spring 15 is arranged between the hollow frame 14 and the sealing plug 16. In the natural state, the spring 15 generates an elastic resisting force on the sealing plug 16, so that the end face of the sealing plug 16 abuts against the inner wall of the liquid storage chamber 12. The elastic resisting force of the spring 15 on the sealing plug 16 makes the end face of the sealing plug 16 abut against the inner wall of the liquid storage chamber 12. Since the positive projection area of ​​the sealing plug 16 covers a plurality of capillary liquid inlet holes 19, the abutting surface of the sealing plug 16 and the liquid storage chamber 12 is in a liquid-tight state;

[0044] Please refer to Figure 3When the floating pin 17 contacts the pipe, the pipe may not be able to smoothly drive the floating pin to move. Therefore, in this embodiment, a ball head 18 is provided at one end of the floating pin 17 that penetrates the through hole 9. After the pipe penetrates the through hole, the ball head will slide relatively, thereby smoothly driving the floating pin 17 to move.

[0045] Please refer to Figure 3 Since the sealing plug is coaxially connected to the floating pin 17, in order for the sealing plug to effectively seal the capillary liquid inlet hole 19, in this embodiment, a plurality of capillary liquid inlet holes 19 are arranged in an axial array along the floating pin 17, and the floating pin 17 is located between the plurality of capillary liquid inlet holes 19, so that the sealing plug 16 can effectively seal the capillary liquid inlet hole 19;

[0046] Please refer to Figure 2 , 4 Since it is necessary to replenish the liquid rust remover in the liquid storage chamber 12, in this embodiment, the end of the handle 6 away from the mounting seat 5 is set to be open, and the inner wall of the open end is threadedly connected with an end cover 11, and the end cover 11 is provided with a pipe joint 7 connected to an external air compression device, and the pipe joint 7 is connected to the inside of the air storage chamber 13, so that the external air compression device can deliver compressed air to the air storage chamber through the pipe joint 7, thereby generating a large air pressure thrust on the piston. In addition, the piston can be taken out from the handle, thereby facilitating the replenishment of the liquid rust remover inside the liquid storage chamber. In addition, in order to facilitate the disassembly and reset of the piston, a tension spring can be installed in the air storage chamber 13, and the two ends of the tension spring are respectively fixed to the piston 10 and the end cover 11. In this way, when the air pressure in the air storage chamber is reduced, the tension spring can generate tension on the piston, thereby resetting the piston. At the same time, after removing the end cover, the piston can be easily taken out, thereby facilitating the piston to be separated from the handle.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
