Description

Technical Field

[0001] The utility model relates to the technical field of pipeline plugging devices, in particular to a rotary fan type pipeline plugging device. Background Technique

[0002] Before the pipeline enters the sandblasting machine or shot blasting machine, in order to prevent sand or steel shot from entering the pipeline interior, the pipe orifice must be plugged. Although plastic plugs are generally supplied with the pipeline materials during ordering, this kind of plug has four disadvantages. First, it is not resistant to high temperature. Under the high-speed impact of sand or steel shot, it is easy to generate heat and cause a fire. Second, the installation and removal of such pipe orifice plugs are laborious and time-consuming, and the slow speed affects the work efficiency. Third, it is easy to be damaged and has a low turnover rate. Fourth, the outer diameters of metric and imperial pipelines are slightly different. For example, the outer diameter of a DN150 metric pipe is 159 mm, and the outer diameter of an imperial pipe is 168 mm. Therefore, the plugs used cannot be universal.

[0003] The utility model with the publication number of CN217463703U relates to a rotary fan type pipeline plugging device, which includes a plurality of rotary fan blades. Any one of the rotary fan blades includes a fan-shaped fan surface and a fan bone. The front end of the fan surface is bent towards the back to form a folded edge part. A long circular arc-shaped rotating groove is opened on the folded edge part. A limiting nail is arranged on the front surface of the folded edge part near one end of the rotating groove. A fan bone slot is arranged in the middle of the front surface of the fan surface. The upper part of the fan bone is inserted into the fan bone slot, and a round hole is opened at the lower part of the fan bone; the plurality of rotary fan blades are connected by a rotating shaft passing through the round holes; the limiting nail on any one of the rotary fan blades is inserted into the rotating groove of the adjacent rotary fan blade. After the rotary fan blades are rotated and opened to form a circle, the circular hoop formed by the folded edge part of the fan surface is sleeved on the pipeline to plug the pipe orifice. The depth of insertion of the fan bone into the fan bone slot can be adjusted to meet the adjustment requirements of the pipeline outer diameter difference.

[0004] When the plugging device disclosed in the above utility model is used, different numbers of fan surfaces are required for pipelines of different sizes, and the practicability is relatively low. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments.

[0021] Refer to Figures 1-4 , the rotary fan type pipeline plugging device includes a first connecting plate 1 and a second connecting plate 2. A same driving wheel 3 is rotatably connected between the first connecting plate 1 and the second connecting plate 2. A rotating shaft 4 is connected to the center of the driving wheel 3. One end of the rotating shaft 4 passes through the first connecting plate 1 and is slidably connected with a handwheel 5. A plurality of arc grooves 6 are formed on the driving wheel 3. A moving rod 7 is slidably connected in the arc groove 6. The outer end of the moving rod 7 is provided with a first isolation plate 8. Both the moving rod 7 and the first isolation plate 8 are slidably connected on the first connecting plate 1.

[0022] When using this plugging device, first place it inside the pipeline, and then rotate the handwheel 5. The rotation of the handwheel 5 drives the synchronous rotation of the rotating shaft 4, so that the driving wheel 3 installed on the rotating shaft 4 rotates, causing a plurality of moving rods 7 and the first isolation plate 8 slidably connected to the driving wheel 3 through the arc grooves 6 to move synchronously towards the outside of the plugging device, so that a plurality of first isolation plates 8 are in contact with the inner wall surface of the pipeline, thereby achieving the function of isolating the pipeline from the outside. This plugging device is simple to operate, can meet the use requirements of pipelines of different specifications, and has high practicability.

[0023] Specifically, in this embodiment, connecting shafts 9 are installed at the mutually close ends of a plurality of moving rods 7. The connecting shafts 9 are slidably adapted in the corresponding arc grooves 6, so that when the driving wheel 3 rotates, it drives the synchronous movement of the arc grooves 6, thereby promoting the movement of the connecting shafts 9, driving the movement of a plurality of moving rods 7, and controlling the distance between the first isolation plate 8 and the inner wall surface of the pipeline.

[0024] Specifically, in this embodiment, a plurality of moving grooves 10 are formed on one side of the first connecting plate 1 close to the second connecting plate 2. The moving grooves 10 are adapted to the whole formed by the moving rod 7 and the first partition plate 8, so that when the moving rod 7 moves, it can only move along the direction restricted by the moving grooves 10, thereby avoiding deviation when the moving rod 7 moves. At the same time, the arrangement of the moving grooves 10 provides a receiving space for the first partition plate 8, further reducing the occupied space of the plugging device.

[0025] Specifically, in this embodiment, a plurality of second partition plates 11 are slidably connected to the second connecting plate 2. The plurality of second partition plates 11 are located at the gaps between the plurality of first partition plates 8, and two third connecting plates 12 are installed on each of the plurality of second partition plates 11. The ends of the two third connecting plates 12 far from the second partition plates 11 are respectively connected to the two corresponding first partition plates 8, so that when the first partition plates 8 move, they can drive the second partition plates 11 to move synchronously to contact the inner wall surface of the pipeline through the third connecting plates 12, thereby plugging the gaps between the first partition plates 8 through the plurality of second partition plates 11, and thus providing comprehensive isolation for the pipeline.

[0026] Specifically, in this embodiment, a plurality of first connecting grooves 13 are formed on one side of the second connecting plate 2 close to the first connecting plate 1. The first connecting grooves 13 are adapted to the second partition plates 11, and both ends of the plurality of first connecting grooves 13 are connected with second connecting grooves 14. Connecting strips 15 are installed at both ends of the plurality of second partition plates 11. The connecting strips 15 are adapted to the second connecting grooves 14, so that the second partition plates 11 can be slidably connected to the second connecting plate 2 through the first connecting grooves 13 and slidably connected in the first connecting grooves 13 through the adaptability of the connecting strips 15 to the second connecting grooves 14, thereby ensuring the connection relationship between the second partition plates 11 and the second connecting plate 2.

[0027] Specifically, in this embodiment, two third connecting grooves 16 are formed on the rotating shaft 4. Two connecting blocks 17 are installed on the handwheel 5. The connecting blocks 17 are slidably adapted in the third connecting grooves 16, so that the handwheel 5 can be slidably connected to the rotating shaft 4 through the adaptability of the connecting blocks 17 to the third connecting grooves 16, and thus driving the rotating shaft 4 to rotate by rotating the handwheel 5, thereby completing the driving of the transmission wheel 3.

[0028] Specifically, in this embodiment, a positioning shaft 18 is installed on one side of the handwheel 5 close to the first connecting plate 1. A number of positioning holes 19 are formed in the first connecting plate 1. The positioning holes 19 are adapted to the positioning shaft 18. At the same time, springs 20 are installed on both connecting blocks 17, and the other ends of the springs 20 are installed on the third connecting groove 16. After isolating the pipeline, the user can move the position of the handwheel 5 on the rotating shaft 4, insert the positioning shaft 18 into the corresponding positioning hole 19, and the spring 20 provides pressure for the handwheel 5, so as to ensure the connection state between the positioning shaft 18 and the positioning hole 19, so that the plugging device can be locked on the inner wall of the pipeline, thereby ensuring the connection stability between the plugging device and the pipeline.

[0029] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
