Description

Technical Field

[0001] This utility model belongs to the technical field of coke pusher auxiliary equipment, and specifically relates to a novel coke pusher guide device. Background Technology

[0002] The coke pusher is a key component of the coke oven machinery and equipment, and plays an important role in coke production by pushing out the mature coke from the carbonization chamber.

[0003] When the coke pusher is in use, it is powered by a coke pusher motor and driven by a coke pusher reducer, which drives the coke pusher to reciprocate in the carbonization chamber, thereby pushing the coke out of the carbonization chamber. However, due to the innovation of coke oven technology, the carbonization chamber has been lengthened, resulting in a larger coke pusher stroke. When the coke pusher returns at the end of the coke pusher process, the swing of the coke pusher will increase. This swinging coke pusher will damage the carbonization chamber, thereby affecting the service life of the carbonization chamber.

[0004] Therefore, this utility model provides a novel coke pusher guide device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel coke pusher guide device, which aims to solve the problem in the prior art that the existing coke pusher swings more when it returns at the end of the coke pushing process, which causes damage to the carbonization chamber and thus affects the service life of the carbonization chamber.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel coke pusher guide device, comprising a coke pusher body, a coke pusher head connected to one end of the coke pusher body, and mounting blocks fixedly connected to both ends of the coke pusher body near the coke pusher head. A placement groove is formed on the end surface of the mounting block away from the coke pusher body, and a connecting block is connected to the inner surface of the placement groove. Guide rollers are symmetrically fixedly connected to the end surface of the connecting block away from the mounting block. Limiting holes are formed on both sides of the mounting block, and fixing bolts are passed through the limiting holes. The other end of the fixing bolts extends into the fixing holes, and the fixing holes are formed on both sides of the connecting block.

[0007] In a preferred embodiment of this novel coke pusher guide device, the connecting block is slidably connected to the mounting block via a placement groove.

[0008] In a preferred embodiment of this novel coke pusher guide device, the position and size of the limiting hole match the position and size of the fixing hole, and the fixing bolt forms a threaded connection by passing through the limiting hole and the fixing hole.

[0009] As a preferred embodiment of the novel coke pusher guide device of this utility model, a heat insulation gasket is provided between the fixing bolt and the mounting block, and the heat insulation gasket is made of ceramic fiber material.

[0010] As a preferred embodiment of the novel coke pusher guide device of this utility model, a threaded mounting groove is provided on one side surface of the mounting block outside the limiting hole. A sealing gasket is slidably placed inside the threaded mounting groove, and a threaded ring is also threadedly connected inside the threaded mounting groove. A cover is connected to the other end of the threaded ring.

[0011] As a preferred embodiment of the novel coke pusher guide device of this utility model, the size of the cover is larger than the size of the fixing bolt, the outer surface of the cover is coated with a high-temperature resistant coating, and the sealing gasket is made of graphite.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention fixes the connecting block in the mounting slot by placing the connecting block into the mounting slot, and then using the cooperation of the fixing bolt and the heat insulation gasket to tighten the fixing bolt through the limiting hole into the fixing hole. This allows the connecting block with guide rollers to be installed in the mounting block on the coke pusher body. In this way, the front part of the coke pusher body will be equipped with two sets of guide rollers. When the coke pusher body moves in the carbonization chamber, the guide rollers will slide along the inner wall of the carbonization chamber, thereby restricting the movement trajectory of the coke pusher body and allowing the coke pusher body to move smoothly in the carbonization chamber. This prevents the coke pusher body from swinging and damaging the carbonization chamber, thereby improving the service life of the carbonization chamber.

[0014] This invention utilizes the cooperation of a sealing gasket, a threaded ring, and a retaining cover. The threaded ring connected to the retaining cover is screwed into the threaded mounting groove, thus fixing the retaining cover onto the mounting block. At this point, the threaded ring comes into contact with the sealing gasket, thereby improving the sealing performance between the threaded ring and the mounting block. The retaining cover can also shield and protect the fixing bolts, thereby reducing environmental corrosion of the fixing bolts, increasing the service life of the fixing bolts, and ensuring the stability of the fixing bolt connection.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a novel coke pusher guide device, comprising a coke pusher body 1, a coke pusher head 2 connected to one end of the coke pusher body 1, and mounting blocks 3 fixedly connected to both ends of the coke pusher body 1 near the end of the coke pusher head 2. A placement groove 4 is opened on the end surface of the mounting block 3 away from the coke pusher body 1, and a connecting block 5 is connected to the inner surface of the placement groove 4. Guide rollers 6 are symmetrically fixedly connected to the end surface of the connecting block 5 away from the mounting block 3. Limiting holes 7 are opened on both sides of the mounting block 3, and fixing bolts 8 are connected through the limiting holes 7. The other end of the fixing bolts 8 extends into fixing holes 9, and fixing holes 9 are opened on both sides of the connecting block 5.

[0023] Preferably, the connecting block 5 is slidably connected to the mounting block 3 through the placement groove 4, the position and size of the limiting hole 7 are matched with the position and size of the fixing hole 9, and the fixing bolt 8 is threadedly connected between the limiting hole 7 and the fixing hole 9.

[0024] In practical use, the connecting block 5 can slide in the placement groove 4 on the mounting block 3. When the connecting block 5 is slid into the placement groove 4 on the mounting block 3, the fixing hole 9 on the connecting block 5 will move to the position of the limiting hole 7 on the mounting block 3. At this time, the fixing bolt 8 is screwed into the fixing hole 9 through the limiting hole 7, so that the position of the connecting block 5 can be fixed in the placement groove 4 on the mounting block 3.

[0025] Preferably, a heat insulation gasket 10 is provided between the fixing bolt 8 and the mounting block 3, and the heat insulation gasket 10 is made of ceramic fiber material.

[0026] In practical use, first, use the fixing bolt 8 to pass through the heat insulation gasket 10, and then pass the other end of the fixing bolt 8 through the limiting hole 7 and screw it into the fixing hole 9. At this time, the fixing bolt 8 will be installed on the mounting block 3, so that the heat insulation gasket 10 can be positioned between the fixing bolt 8 and the mounting block 3. The heat insulation gasket 10 is made of ceramic fiber material, which makes the heat insulation gasket 10 have a low thermal conductivity, allowing the heat insulation gasket 10 to cut off part of the heat transfer path and reduce the heat conducted to the fixing bolt 8.

[0027] Preferably, a threaded mounting groove 11 is provided on one side surface of the mounting block 3 outside the limiting hole 7, a sealing gasket 12 is slidably placed inside the threaded mounting groove 11, and a threaded ring 13 is also threadedly connected inside the threaded mounting groove 11, with a cover 14 connected to the other end of the threaded ring 13.

[0028] In practical use, the threaded ring 13 connected to the cover 14 is screwed into the threaded mounting groove 11, so that the cover 14 is fixed on the mounting block 3. At this time, the threaded ring 13 will contact the sealing gasket 12, thereby improving the sealing between the threaded ring 13 and the mounting block 3. At this time, the cover 14 can shield and protect the fixing bolt 8, improving the protection of the fixing bolt 8. By twisting the cover 14 in the opposite direction, the threaded ring 13 can be separated from the threaded mounting groove 11, and the cover 14 can be removed. At this time, the fixing bolt 8 will be exposed again, allowing the operator to operate the fixing bolt 8 normally.

[0029] Preferably, the size of the cover 14 is larger than the size of the fixing bolt 8, the outer surface of the cover 14 is coated with a high temperature resistant coating 15, and the sealing gasket 12 is made of graphite.

[0030] In practical use, the cover 14 can completely cover the protruding part of the fixing bolt 8. The outer surface of the cover 14 is coated with a high-temperature resistant coating 15 of alumina ceramic coating, which makes the cover 14 heat-insulating, high-temperature resistant and wear-resistant. It can effectively block heat transfer and reduce the impact of high temperature on the fixing bolt 8. The sealing gasket 12 is a graphite sealing gasket, which allows the sealing gasket 12 to be used in high-temperature environments.

[0031] It should be noted that the connecting block 5 and the guide roller 6 can be customized to produce the required shape and size for use. After the connecting block 5 and the guide roller 6 are installed, the guide roller 6 can contact the inner wall of the carbonization chamber and roll on the inner wall of the carbonization chamber. Furthermore, the two guide rollers 6 set on one connecting block 5 constitute a group.

[0032] Working principle: When using this new type of coke pusher guide device, slide one end of the connecting block 5 into the placement groove 4 on the mounting block 3, so that the fixing hole 9 on the connecting block 5 coincides with the position of the limiting hole 7. Then, use the fixing bolt 8 to pass through the heat insulation gasket 10, and then screw one end of the fixing bolt 8 through the limiting hole 7 into the fixing hole 9. This fixes the position of the connecting block 5 in the placement groove 4 on the mounting block 3. At this time, the connecting block 5, along with the guide roller 6, will be fixed in the mounting block 3 on the coke pusher body 1. After both connecting blocks 5 are installed, two sets of guide rollers 6 will be set at the front end of the coke pusher body 1. When the coke pusher body 1 is powered by the coke pusher motor and driven by the coke pusher reducer, the rotating shaft connected to the coke pusher reducer will drive the coke pusher drive gear to rotate, so that the coke pusher drive gear drives the coke pusher rod through the coke pusher rack on the coke pusher body 1. The main body 1 reciprocates within the carbonization chamber. As the coke pusher body 1 moves within the carbonization chamber, the two sets of guide rollers 6 at the front end of the coke pusher body 1 slide along the inner wall of the carbonization chamber, thereby restricting the movement trajectory of the coke pusher body 1 and allowing it to move smoothly within the carbonization chamber. This prevents the coke pusher body 1 from swaying and damaging the carbonization chamber, thus improving the service life of the carbonization chamber. Secondly, after the fixing bolts 8 are installed, the sealing gasket 12 is first placed into the threaded mounting groove 11, and then the threaded ring 13 on the cover 14 is screwed into the threaded mounting groove 11. At this time, the cover 14 is fixed to the mounting block 3 through the threaded ring 13. In this way, the cover 14 will cover the fixing bolts 8, thereby improving the protection of the fixing bolts 8, reducing the corrosion of the fixing bolts 8 by the environment, improving the service life of the fixing bolts 8, and ensuring the stability of the connection of the fixing bolts 8.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
