Description

Technical Field

[0001] The utility model relates to a pipeline dredging device, in particular to a coking oven gas pipeline blockage dredging device, belonging to the technical field of pipeline dredging. Background Technique

[0002] In the coking production process, the smoothness of the coking oven gas pipeline is crucial. However, since the gas contains impurities such as coal tar and dust, long-term operation will cause sediments to adhere to the inner wall of the pipeline. Moreover, during daily production, intense vibration during the coal charging process may cause dust, broken bricks, etc. to fall into the brick gas duct and then enter the coking oven gas channel, bonding with moisture and tar in the gas to cause blockage, thus affecting production efficiency and equipment safety. Traditional dredging methods include mechanical cleaning and chemical cleaning. Mechanical cleaning mostly uses tools such as iron wires and steel wires for manual dredging, which is complex in operation and easy to damage the pipeline. Chemical cleaning is inefficient and difficult to completely clean the inner wall of the pipeline, and it will also damage the pipeline.

[0003] For example, a "coking oven gas pipeline blockage spiral cone dredging tool" disclosed in a Chinese patent document, with the publication number CN221109258U, includes a vertical pipe. A horizontal plate is fixedly connected to the lower part of the inner wall of the vertical pipe. One-way valves are fixedly connected to both inner walls of the horizontal plate. A threaded rod is rotatably connected to the inner wall of the horizontal plate through a bearing. A spiral cone is threadedly connected to the outer wall of the threaded rod. A limiting rod is movably connected to the inner wall of the spiral cone. The bottom of the limiting rod is fixedly connected to the top of the horizontal plate. This dredging tool can perform rapid cleaning operations without opening the coking oven.

[0004] Through the above patent search and analysis of related dredging tools on the market, it is found that the above patent still has the following defects: 1. The operation range is limited and it is only suitable for dredging short coking oven gas pipelines; 2. It still uses a cleaning liquid for cleaning. On the one hand, it is easy to damage the pipeline, and on the other hand, it cannot completely clean stubborn dirt, resulting in poor cleaning efficiency and effect. Summary of the Utility Model

The components or equipment in the following embodiments are all general standard parts or components known to those skilled in the art, and their structures and principles can all be known through technical manuals or obtained through conventional experimental methods by those skilled in the art.

[0033] Embodiment 1:

[0034] As Figure 1 , 2 shown, the present utility model provides a technical solution, a coke oven gas pipeline blockage dredging device, which is composed of a walking component and a dredging component.

[0035] Specifically, the walking component is used to carry the entire dredging device, contact with the inner wall of the coke oven gas pipeline, drive the dredging device to move back and forth along the length direction of the coke oven gas pipeline, and move the dredging device to the position where dredging is required.

[0036] Specifically, the dredging component can quickly and effectively remove the blockage in the pipeline. It is composed of a first motor 1, a rotating plate 2, a first cleaning piece 3, a second cleaning piece 4 and a drill bit 5. The first motor 1 is horizontally installed in the walking component, and the output shaft 6 of the first motor 1 extends out of the front end of the walking component and is fixedly connected to the middle part of the rear side surface of the rotating plate 2 by bolts. The drill bit 5 is bolted or welded to the middle part of the front side surface of the rotating plate 2. The first cleaning piece 3 is welded to the front side surface of the rotating plate 2, and the second cleaning piece 4 is welded to the side wall of the rotating plate 2. Both the first cleaning piece 3 and the second cleaning piece 4 are evenly arranged in a circle along the axis of the rotating plate 2. And the rotating surface of the first cleaning piece 3 should be larger than the maximum rotating surface of the drill bit 5. The outer edge of the second cleaning piece 4 is close to the inner wall of the coke oven gas pipeline. It should be noted here that in this embodiment, the dredging component is the front end or the front side, and the walking component is the rear end or the rear side.

[0037] Embodiment 2:

[0038] As Figure 6 、 7 shown, the present utility model provides another technical solution, a coke oven gas pipeline blockage dredging device. The difference from Embodiment 1 is that the walking component includes a front-end mounting plate 7, a rear-end mounting plate 8 and a plurality of fixed guide rods 9 located between the front-end mounting plate 7 and the rear-end mounting plate 8. A plurality of fixed guide rods 9 are evenly arranged in a circle, and both ends of the fixed guide rods 9 are fixedly connected to the front-end mounting plate 7 and the rear-end mounting plate 8 by bolts. Two sets of walking parts are arranged along the length direction of the fixed guide rods 9.

[0039] Specifically, as Figure 8As shown in the figure, each set of walking components consists of a fixed disk 10, a walking wheel set 11 and a supporting wheel set 12. The fixed disk 10 is fixedly installed on the fixed guide rod 9. There are two sets of walking wheel sets 11 symmetrically arranged with a left-right downward inclination, and one set of supporting wheel sets 12 is arranged vertically upward. In this embodiment, the included angle between the two sets of walking wheel sets 11 is 100 degrees, and the included angle between the walking wheel set 11 and the supporting wheel set 12 is 130 degrees. Both the above-mentioned walking wheel set 11 and the supporting wheel set 12 include two connecting rods 13. A fixed rod 14 is fixedly installed at a position close to the fixed disk 10 between the two connecting rods 13. A supporting plate 15 is fixedly installed at a position far from the fixed disk 10 between the two connecting rods 13. And a vehicle axle 16 is rotatably connected to the ends of the two connecting rods 13 far from the fixed disk 10. The two ends of the vehicle axle 16 pass through the connecting rods 13 and are fixedly connected with wheels 17. And the connecting rod 13 on the walking wheel set 11 is fixedly connected to the side wall of the fixed disk 10 through bolts. The connecting rod 13 on the supporting wheel set 12 is rotatably connected to the side wall of the fixed disk 10 through a rotating shaft, and the supporting wheel set 12 can rotate back and forth along the fixed disk 12.

[0040] Specifically, a first linkage rod 18 is connected between the two fixed rods 14 on the two sets of supporting wheel sets 12. The two ends of the first linkage rod 18 are respectively rotatably connected between the two fixed rods 14. A parallelogram structure is formed by the two fixed disks 10, the two sets of connecting rods 13 and the first linkage rod 18, so that the two sets of supporting wheel sets 12 can rotate synchronously.

[0041] Specifically, a sliding disk 19 is also slidably connected to the fixed guide rod 9. The sliding disk 19 is located between the rear fixed disk 10 and the rear end mounting plate 8. And a guiding column 20 is fixedly installed between the rear fixed disk 10 and the rear end mounting plate 8 through bolts. The guiding column 20 penetrates through the sliding disk 19, and a compression spring 21 is sleeved on the guiding column 20. The compression spring 21 is located between the sliding disk 19 and the rear end mounting plate 8. The upper side wall of the sliding disk 19 is also rotatably connected with a set of second linkage rods 22 through a rotating shaft. The upper end of the second linkage rod 22 is rotatably connected to the fixed rod 14 on the rear supporting wheel set 12. When the dredging device needs to be placed in the coke oven gas pipeline for operation, the two sets of supporting wheel sets 12 will rotate and incline towards the rear end mounting plate 8. Under the action of the first linkage rod 18 and the second linkage rod 22, the sliding disk 19 moves backward along the length direction of the guiding column 20, thereby squeezing the compression spring 21. Under the spring force of the compression spring 21, the wheels 17 of the walking assembly are closely attached to the inner wall of the pipeline, ensuring the stability of the walking support of the entire dredging device.

[0042] Specifically, as Figure 9As shown in the figure, a second motor 23 is mounted on the support plate 15 by bolts. The output end of the second motor 23 passes through the support plate 15 and is fixedly sleeved with a first bevel gear 24. The side wall of the axle 16 is fixedly sleeved with a second bevel gear 25. The first bevel gear 24 and the second bevel gear 25 are meshed and connected. By starting the second motor 23, under the action of the first bevel gear 24 and the second bevel gear 25, the axle 16 and the wheels 17 can rotate to drive the entire dredging device to move forward or backward.

[0043] Specifically, a gear sleeve 26 is also mounted between the end of the connecting rod 13 and the support plate 15 by bolts. The first bevel gear 24 and the second bevel gear 25 are both located inside the gear sleeve 26, which has a good protection effect.

[0044] Specifically, as Figure 5 shown, a protective outer cover 27 is fixedly mounted between the side walls of the front mounting plate 7 and the rear mounting plate 8 by bolts. The protective outer cover 27 is provided with a through hole 28 for the connecting rod 13 on the traveling wheel set 11 to extend out, and a rotating groove 29 for the connecting rod 13 on the support assembly to rotate. The protective outer cover 27 can play a good protection role to prevent the internal parts from being damaged under external forces.

[0045] Embodiment 3:

[0046] As Figure 3 、 4 shown, the present utility model provides another technical solution, a coke oven gas pipeline blockage dredging device, which is different from that in Embodiment 1 in that in this embodiment, the drill bit 5 adopts a stepped drill, which has a good drilling effect. The second cleaning piece 4 is in an L-shaped structure, which can ensure that the inner wall of the coke oven pipeline is basically scraped clean and effectively remove the blockage in the pipeline. It should be noted here that the drill bit 5, the rotating plate 2, the front mounting plate 7, the fixed disk 10, the first motor 1, the sliding disk 19, the guide post 20 and the rear mounting plate 8 in the present application are coaxially arranged; and the present utility model should be equipped with an external controller. The controller is electrically connected to the first motor 1 and the second motor 23 through wires, and the movement of the traveling component and the operation of the dredging component are realized by operating the controller. The controller is also connected to a power supply. The specific structures and circuit connections of the above-mentioned controller and power supply are not within the protection scope of the present application, and those skilled in the art can obtain them through the common general knowledge, conventional means or simple derivation in the art, and will not be elaborated here.

[0047] The utility model provides a walking wheel set, a supporting wheel set, a first linkage rod, a second linkage rod, a sliding disc, a guiding column and a compression spring. When the dredging device needs to be placed in the coke oven gas pipeline for operation, the two supporting wheel sets will tilt towards the position of the rear mounting plate. Under the action of the first linkage rod and the second linkage rod, the sliding disc moves backward along the length direction of the guiding column, thereby squeezing the compression spring. Under the spring force of the compression spring, the wheels of the walking assembly are closely attached to the inner wall of the pipeline, ensuring the stability of the walking support of the entire dredging device. And by carrying the corresponding dredging assembly, drilling and cleaning of the blocked part in the pipeline can be realized; through the provided first cleaning piece, second cleaning piece and drill bit, the drill bit is used to drill into the blockage, and can easily penetrate the blockage. The combined use of the first cleaning piece and the second cleaning piece can basically clean the blockage on the inner wall of the pipeline completely, ensuring the reliability of the dredging operation; through the provided walking assembly and dredging assembly, the blockage in the pipeline can be quickly and effectively removed, while ensuring the safety of the operation, reducing the damage to the pipeline, and improving the efficiency of the dredging work.
