[0030] Please refer to Figure 1 - Figure 6 The present application provides a kind of rotary kiln burner coking cleaning tool auxiliary device, including support assembly, cylinder 3 and two limit rings 4.

[0031] The support assembly is arranged outside the kiln head cover 1 and is fixedly connected with the kiln head cover 1, and the support assembly comprises two mounting seats 2, the two mounting seats 2 are fixed on the kiln head cover 1 respectively, and the two mounting seats 2 are located on the opposite sides of the observation hole 10 on the kiln head cover 1 in the axial direction of the cylinder 3. The cylinder 3 is horizontally arranged on the support assembly, the opposite ends of the cylinder 3 are arranged on the two mounting seats 2 of the support assembly respectively, the limiting rings 4 are coaxially arranged with the cylinder 3, the axial direction of the cylinder 3 is perpendicular to the direction in which the cleaning tool 8 is inserted into the observation hole 10 from the kiln head cover 1, the cylinder 3 is used for supporting the cleaning tool 8, the height of the position on the cylinder 3, which is in contact with the cleaning tool 8, from the ground is greater than the height between the bottom surface in the observation hole 10 and the ground and is less than the height between the top surface in the observation hole 10 and the ground, and the position on the cylinder 3, which is in contact with the cleaning tool 8, is used as the fulcrum of the cleaning tool 8 for up-down swinging. The two limiting rings 4 are arranged at the opposite ends of the cylinder 3 respectively, the two limiting rings 4 are used for limiting the movement of the cleaning tool 8 in the axial direction of the cylinder 3, and the spacing between the two limiting rings 4 is less than the inner diameter of the observation hole 10 in the axial direction of the cylinder 3.

[0032] As can be seen from the above, when the auxiliary device for the rotary kiln burner coking cleaning tool is used, the support assembly is fixed on the kiln head cover 1, when the operator uses the cleaning tool 8 to pass through the observation hole 10 on the kiln head cover 1 to knock off the coking block on the head end surface 90 of the burner 9, the cleaning tool 8 is supported by the cylinder 3, so that the cleaning tool 8 is prevented from contacting the bottom surface in the observation hole 10, the friction between the cylinder 3 and the cleaning tool 8 is rolling friction, and the spacing between the two limiting rings 4 is less than the inner diameter of the observation hole 10 in the axial direction of the cylinder 3, so that the frictional force between the barrel rod and the observation hole 10 can be effectively reduced.

[0033] In addition, the position on the cylinder 3, which is in contact with the cleaning tool 8, is used as the fulcrum of the cleaning tool 8 for up-down swinging, which is beneficial to the up-down swinging of the cleaning tool 8, so that the operator can save labor during the up-down swinging of the cleaning tool 8 around the fulcrum, that is, the operator can use the lever principle to reduce the labor intensity during the up-down swinging of the cleaning tool 8 for cleaning the coking block. The limiting rings 4 arranged at the opposite ends of the cylinder 3 limit the movement of the cleaning tool 8 in the axial direction of the cylinder 3, that is, the two limiting rings 4 have a correcting effect on the coking tool, which is beneficial to grasping the operation direction of the coking tool for prying and knocking the coking block.

[0034] In addition, since the position on the cylinder 3, which is in contact with the cleaning tool 8, is used as the fulcrum of the cleaning tool 8 for up-down swinging, the operator can find the feeling of playing a seesaw when using the auxiliary device of the embodiment to assist the cleaning tool 8 in cleaning the coking, so that the work interest is increased.

[0035] It should be noted that the height of the cylinder 3 can be reasonably changed according to the actual situation; in addition, the cover plate used to cover the observation port 10 can be arranged in a movable manner up and down, so as to avoid interference with the auxiliary device for the rotary kiln burner coking cleaning tool when opening or closing the cover plate.

[0036] In an embodiment, the cylinder 3 is rotatably arranged on the support assembly, specifically, a rotating shaft 5 is rotatably arranged between the two mounting seats 2, and the cylinder 3 is sleeved and fixed on the rotating shaft 5, so that the cylinder 3 can rotate relative to the support assembly. When the worker pushes the cleaning tool 8 forward to work and pokes the coke block on the head end surface 90 of the burner 9, the rolling force of the cylinder 3 can assist the cleaning to push forward.

[0037] In an embodiment, a limiting seat 6 is further arranged on the support assembly, and the limiting seat 6 is used to prevent the cleaning tool 8 from hitting the upper end of the observation port 10 during vertical movement, so as to avoid damaging the observation port 10 on the kiln head cover 1. Specifically, the limiting seat 6 is a U-shaped limiting frame, and the opposite ends of the U-shaped limiting frame are respectively fixed on the two mounting seats 2. The vertical distance between the U-shaped limiting frame and the bottom surface in the observation port 10 is D1, and the caliber of the observation port 10 in the vertical direction is D2. The relationship between D2 and D1 is: 0.9D2 < D1 < D2. In this way, the upper end of the observation port 10 can be avoided from being hit by the cleaning tool 8 during vertical movement, and at the same time, the vertical distance between the U-shaped limiting frame and the bottom surface in the observation port 10 is not too small, which affects the amplitude of the cleaning tool 8 swinging up and down around the above-mentioned fulcrum.

[0038] In an embodiment, the cleaning tool 8 is a bucket rod, and the limiting rings 4 are adjustably arranged on the cylinder 3 along the axial direction of the cylinder 3, and the limiting rings 4 can be locked on the cylinder 3 by the locking structure arranged on the support assembly. In this way, the spacing between the two limiting rings 4 can be adjusted to adapt to bucket rods of different diameters.

[0039] In an embodiment, the locking structure includes a locking plate 7, and the opposite ends of the locking plate 7 are respectively arranged vertically and slidably on the two mounting seats 2. At least three limiting grooves 70 are formed on the upper surface of the locking plate 7, and the three limiting grooves 70 are arranged at intervals along the axial direction of the cylinder 3. Any two limiting grooves 70 are respectively used for inserting the two limiting rings 4. Specifically, a sliding groove 20 is formed on the mounting seat 2 and penetrates through the opposite surfaces of the mounting seat 2. The sliding groove 20 extends vertically, and the locking plate 7 is in sliding connection with the sliding groove 20. When it is necessary to lock the limiting ring 4 on the cylinder 3, the locking plate 7 is manually moved along the axial direction of the cylinder 3, so that the two limiting grooves 70 on the locking plate 7 are respectively aligned with the two limiting rings 4. Then, the locking plate 7 is manually moved upward, so that the two limiting rings 4 are respectively inserted into the two limiting grooves 70. Finally, the locking plate 7 is locked on the mounting seat 2 by screwing the screw through the screw hole 21 on the mounting seat 2 which is communicated with the sliding groove 20.

[0040] Of course, in other embodiments, the locking structure can also adopt the following structure: a threaded hole is opened on the side wall of the limiting ring 4 along the radial direction, a screw matched with the threaded hole is prepared, and the limiting ring 4 can also be locked on the cylinder 3, and here, the locking structure is not limited, and those skilled in the art can reasonably change the locking structure, which should also fall within the protection scope of the utility model.

[0041] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and equivalent structures or equivalent process transformations using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
