[0027] Example:

[0028] Reference Figure 1-Figure 7 The embodiment of the utility model provides a cleaning device for air duct joints, including a frame 1 with a box body 2 and a shell 3 installed, and also including: a guide tube 4 with through openings at both ends, fixedly connected to the shell 3, wherein two motors 5 are installed on the box body 2, and the output end of the motor 5 extends into the shell 3 and is fixedly connected to a wire brush 6, and a driving part for driving the two motors 5 to move toward and away from each other is provided on the box body 2; two positioning cones 7 are connected to the shell 3 through elastic members, wherein the two positioning cones 7 have different specifications and sizes and are used to support and position air duct joints of different specifications, the positioning cone 7 faces the through opening of the guide tube 4, the positioning cone 7 is located between the two wire brushes 6, and a cleaning part is provided in the box body 2.

[0029] Specifically, during use, the air duct joint can be supported and positioned through the cooperation of the elastic member and the positioning cone 7, which greatly improves the stability of the two wire brushes 6 during the cleaning process of the air duct joint, so as to reduce the offset and shaking of the joint, and avoid excessive cleaning of the joint thread due to workers' inaccurate control of the force, thereby damaging the thread, and can also achieve lateral movement of the air duct joint between the two wire brushes 6, and can change the cleaning position of the wire brush 6 on the air duct joint, thereby improving the cleaning effect of the air duct joint. Through the setting of the cleaning part, it is convenient to centrally clean and collect the cleared raw tape, avoid the cleared raw tape flying all over the sky and causing pollution to the maintenance environment, and ensure the safety and health of the workers.

[0030] The driving part includes a double-headed screw 51 rotatably connected to the box body 2, and both sides of the outer wall of the double-headed screw 51 are threadedly connected with a screw sleeve 52, and the screw sleeve 52 is slidably installed on the box body 2, wherein the top of the screw sleeve 52 is fixedly connected to a movable plate 53, one end of the double-headed screw 51 is fixedly connected to a crank 54, and the motor 5 is fixedly installed on the movable plate 53.

[0031] Specifically, when in use, by turning the crank 54 and driving the double-headed screw 51 to rotate, under the action of opposite threads, the two screw sleeves 52 drive the two movable plates 53 to move away from each other or towards each other, and drive the two motors 5 and the wire brushes 6 to move together, which can facilitate the adjustment of the spacing between the two wire brushes 6, and then the air duct joints of different specifications can be cleaned, indirectly improving the applicability of the device.

[0032] A guide rail 55 is fixedly connected to the top of the box body 2 , a guide block 56 is laterally slidably connected to the guide rail 55 , and the movable plate 53 is fixedly connected to the guide block 56 .

[0033] Specifically, by providing the guide rail 55 and the guide block 56 , the movable plate 53 can be guided to prevent the movable plate 53 and the screw sleeve 52 from rotating together with the double-headed screw 51 .

[0034] The elastic member includes a fixed plate 10 fixedly connected to the shell 3, a movable rod 8 is slidably connected to the fixed plate 10, and a positioning cone 7 is fixedly connected to one end of the movable rod 8, wherein a spring 9 is sleeved on the movable rod 8, and the two ends of the spring 9 are respectively fixedly connected to the surface of the fixed plate 10 and the surface of the positioning cone 7.

[0035] Specifically, through the setting of the fixed plate 10, the movable rod 8 and the spring 9, when the worker presses the air duct joint against the positioning cone 7 and drives the positioning cone 7 to move laterally, the air duct joint can be moved laterally between the two wire brushes 6, and the cleaning position of the wire brush 6 on the air duct joint can be changed, thereby improving the cleaning effect of the air duct joint.

[0036] The cleaning part includes: an air duct 21, which is fixedly connected to the box body 2, wherein the air inlet of the air duct 21 is connected to the shell 3, a collection box 24 is slidably connected to the air duct 21, and a filter element 25 is inserted into the exhaust port of the air duct 21, and the filtering surface of the filter element 25 faces the interior of the collection box 24; a negative pressure part is arranged on the box body 2, wherein the negative pressure part is used to generate a continuous negative pressure in the air duct 21.

[0037] Specifically, when in use, negative pressure is generated in the air duct 21 through the negative pressure piece, which can suck the raw tape removed from the air duct joint during the cleaning process into the air duct 21, and filter the raw tape through the filter element 25, so that the removed raw tape can be easily cleaned and collected in a centralized manner, avoiding the cleaned raw tape from flying all over the sky and causing pollution to the maintenance environment, thereby ensuring the safety and health of the workers.

[0038] The negative pressure member includes a shell 22 fixedly connected to the box body 2 , a fan 23 is fixedly installed inside the shell 22 , and an air inlet of the shell 22 faces the air duct 21 .

[0039] Specifically, when in use, by starting the fan 23, the air in the air duct 21 and the box body 2 can be drawn out to the outside through the shell 22, and a continuous negative pressure can be generated in the air duct 21 to facilitate cleaning of the removed raw tape.

[0040] Working principle: When using the duct joint cleaning device, first insert the duct joint into the housing 3 through the guide tube 4, so that the end of the duct joint rests on the inclined surface of the positioning cone 7, and then start the two motors 5 to drive the two wire brushes 6 to rotate. The two wire brushes 6 clean the raw tape wrapped around the threads of the duct joint. The positioning cone 7 can support and position the duct joint, greatly improving the stability of the duct joint during cleaning, thereby reducing the deviation and shaking of the joint and preventing the worker from excessively cleaning the joint threads due to inaccurate force control, thereby avoiding damage to the threads.

[0041] At the same time, during cleaning, the positioning cone 7 can be elastically supported by the setting of the fixed plate 10, the movable rod 8 and the spring 9. When the worker presses the air duct joint against the positioning cone 7, the positioning cone 7 is driven to move laterally, thereby realizing the lateral movement of the air duct joint between the two wire brushes 6, and changing the cleaning position of the wire brush 6 on the air duct joint, thereby improving the cleaning effect of the air duct joint;

[0042] Moreover, during cleaning, by starting the fan 23, the air in the air duct 21 and the box body 2 can be drawn out to the outside through the outer shell 22, so that a continuous negative pressure is generated in the air duct 21, and the raw tape removed from the air duct joint during the cleaning process can be sucked into the air duct 21, and the raw tape is blocked and filtered by the filter element 25. When the air duct joint is cleaned, the fan 23 can be turned off, so that the raw tape filtered by the filter element 25 falls into the collection box 24, which can facilitate the centralized cleaning and collection of the removed raw tape, avoid the cleaned raw tape flying all over the sky and causing pollution to the maintenance environment, and ensure the safety and health of the workers.

[0043] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
