[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Figure 1 A front view of a cleaning and maintenance auxiliary device in some embodiments or certain embodiments of the present application is shown, Figure 2 A top view of a cleaning and maintenance auxiliary device in some embodiments or certain embodiments of the present application is shown, combined with Figure 1 and Figure 2 The present application provides a cleaning and maintenance auxiliary device for assisting the cleaning and maintenance of a truncated cone-shaped plug core 10, comprising:

[0036] The mounting assembly 1 is provided with an arc-shaped collecting groove 11 for collecting the cleaning liquid of the tap core 10 .

[0037] The support frame 2 is disposed on the mounting assembly 1 and spans across the collecting tank 11 .

[0038] The cylindrical member 3 is rotatably connected to the support frame 2 around its own axis and is opposite to the notch 111 of the collecting tank 11 .

[0039] The support member 4 is connected to the mounting assembly 1 and is located at one end of the collecting tank 11 , and is used to cooperate with the cylindrical member 3 to respectively support the two ends of the tap core 10 .

[0040] The collecting container 5 is communicated with the bottom of the collecting tank 11 to collect the cleaning liquid.

[0041] When the plug core 10 of the coke oven plug needs to be cleaned and maintained, the truncated cone-shaped plug core 10 can be moved above the collecting groove 11 of the mounting assembly 1. The arc-shaped collecting groove 11 matches the shape of the plug core 10, which is convenient for collecting oil stains on the plug core 10 and cleaning liquid. The support frame 2 arranged on the mounting assembly 1 and spanning the collection tank 11 can play the role of supporting and providing an installation space so that the cylindrical member 3 can be rotatably installed on the support frame 2. The cylindrical member 3 is opposite to the notch 111 of the collection tank 11, and cooperates with the support member 4 connected to the mounting assembly 1 and located at one end of the collection tank 11, which can support the two ends of the truncated cone-shaped plug core 10, so that the plug core 10 is suspended on the collection tank 11 through the cylindrical member 3 and the support member 4, and then the plug core 10 is cleaned. The cylindrical member 3 can be rotated relative to the support frame 2, and the plug core 10 can be rotated relative to the cylindrical member 3 and the support member 4 to comprehensively clean the plug core 10. The oil and cleaning liquid in the cleaning process of the plug core 10 fall into the collection tank 11 and enter the collection container 5 connected to the bottom of the collection tank 11. The cleaning liquid and oil are collected, which is not easy to cause pollution to the environment. After the cleaning is completed, the plug core 10 can continue to be placed on the cylindrical member 3 and the support member 4, and the plug core 10 can be rotated to apply grease to the plug core 10 for maintenance. The plug core 10 can be maintained after cleaning, which is beneficial to improving the cleaning and maintenance efficiency of the plug core 10, and to a certain extent solves the technical problems that the plug cleaning and maintenance process is prone to pollution and the cleaning and maintenance efficiency is not ideal.

[0042] It should be noted that the plug core 10, as a part of the coke oven plug, will also be in contact with the gas or oil in the coke oven for a long time, so it needs to be cleaned. There is rotation between the plug core 10 and the plug body, so applying grease when maintaining the plug core 10 can extend the service life of the plug core 10. One end of the plug core 10 is provided with a coaxial annular protrusion 1031, and the other end is a flange ring 1032 connected to the main shaft 101. The two ends can cooperate with the support member 4 and the cylindrical member 3 respectively, and the plug core 10 can also be rotated as a whole by rotating the main shaft 101. The collecting groove 11 is arc-shaped, and the cross section of the collecting groove 11 is arc-shaped.

[0043] In some embodiments, along the axial direction of the collecting groove 11 , the diameter corresponding to the collecting groove 11 changes gradually.

[0044] The diameter corresponding to the collecting groove 11 gradually changes in the axial direction of the collecting groove 11, so as to be compatible with the truncated cone-shaped tap core 10 with a gradually changing diameter, and is beneficial to collecting oil stains of the tap core 10 and cleaning liquid.

[0045] In some embodiments, the end of the collecting groove 11 with a smaller diameter is higher than the other end of the collecting groove 11 , and the end of the collecting groove 11 with a smaller diameter passes through the mounting assembly 1 .

[0046] The end of the collecting groove 11 with a smaller diameter is higher than the other end of the collecting groove 11, so the end of the collecting groove 11 with a larger diameter has a larger space and a lower position, which is conducive to collecting oil and cleaning liquid, and reducing the pollution caused by oil and cleaning liquid. The end of the collecting groove 11 with a smaller diameter passes through the mounting assembly 1, which is convenient for moving the plug core 10 into the collecting groove 11, which is conducive to improving the efficiency of cleaning and maintenance.

[0047] In some embodiments, the collecting groove 11 may also be configured as an arc-shaped groove with a constant diameter and a height difference at both ends.

[0048] In some embodiments, the axis of the cylindrical member 3 extends along the axial direction of the collecting tank 11. It is convenient for the cylindrical member 3 to cooperate with the support member 4 at one end of the collecting tank 11 to support both ends of the plug core 10, and when the plug core 10 rotates, the interval between the plug core 10 and the collecting tank 11 is relatively fixed, which is convenient for cleaning and maintenance of the plug core 10, and is conducive to improving the cleaning and maintenance efficiency of the plug core 10.

The slide seat 23 may be provided with a first positioning hole 231, and the guide rail 12 may be provided with a second positioning hole 121. Fasteners 6 such as bolts or studs may be inserted into the first positioning hole 231 or the second positioning hole 121 in sequence to fix the slide seat 23 and the guide rail 12. It is convenient for preparation and implementation.

[0053] In some embodiments, one end of the cylindrical member 3 is opposite to the support member 4 , and at least two support members 4 are distributed at intervals along the circumference of the collecting tank 11 .

[0054] One end of the cylindrical member 3 is opposite to the support member 4. When the plug core 10 is supported on the cylindrical member 3 and rotates, the other end of the plug core 10 is supported on the support member 4 to facilitate rotation. At least two support members 4 are distributed at intervals along the circumference of the collecting groove 11. This facilitates stable support of the plug core 10 and rotation of the plug core 10.
