Description

Technical Field

[0001] This invention relates to the field of coke oven door cleaning technology, and in particular to a coke oven door cleaning device based on motor drive. Background Technology

[0002] In the coking production process, the sealing performance of the coke oven door and the carbonization chamber directly depends on the tight fit between the door blade and the door frame. During the high-temperature dry distillation of coal, tar, graphite, and other sticky deposits are generated. These deposits easily accumulate on the surface of the door bricks and the web of the blade. If these deposits accumulate for a long time without timely cleaning, they will damage the sealing effect of the blade, causing the door to not close properly and flue gas to leak out. This not only affects production stability but also causes serious environmental pollution problems.

[0003] Existing coke oven door cleaning devices use a frame adapted to the oven door size, with a drive mechanism moving the blades to complete the cleaning. However, these devices generally lack an oven door alignment and locking mechanism, making it difficult to achieve high-precision positioning between the cleaning device and the oven door. This reduces the thoroughness of the cleaning, affects the cleaning effect, and easily causes damage to the oven door due to relative displacement during the cleaning process. Summary of the Invention

[0004] To address the technical problem of existing coke oven door cleaning devices lacking an alignment and locking mechanism for the oven door, this invention provides a coke oven door cleaning device based on motor drive.

[0005] Therefore, the present invention provides the following technical solution: A coke oven door cleaning device based on motor drive includes a frame, a closed track, a cleaning trolley, a drive unit, a pressure-bearing adjustment device, and a positioning and locking device. The closed track is vertically installed in the frame through the pressure-bearing adjustment device, and the cleaning trolley is slidably installed on the closed track. The drive unit includes a drive motor, a rack, a gear, and a connecting base. The rack is installed on the front and rear sides of the closed track, the gear is installed on the output end of the drive motor, and the gear meshes with the rack. The connecting base is located on the side of the rack away from the gear and is connected to the cleaning trolley. The locking devices are installed in pairs on opposite sides of the frame corresponding to the coke oven door. The positioning locking device includes a sliding plate, a locking cylinder, a first guide frame, and a locking head. The first guide frame is installed on the frame of the coke oven door cleaning device. The sliding plate is slidably installed on the first guide frame. First limiting plates are provided on both sides of the sliding plate. The first limiting plates have strip-shaped first limiting holes perpendicular to the sliding plate's movement direction. One end of the locking cylinder is installed on the sliding plate, and the other end of the locking cylinder is installed on the first guide frame. The first guide frame connects two second limiting plates. The second limiting plates have strip-shaped second limiting holes perpendicular to the first limiting holes. The locking head has a second pin and a first pin corresponding to the first and second limiting holes, respectively. There is a certain radial distance between the first pin and the second pin.

[0006] Furthermore, the closed track includes two oppositely arranged track supports of the same shape. The track supports are rectangular with rounded corners. A trolley track is provided on one side opposite to the two track supports. A limiting strip with a triangular cross-section is provided inward along the opening edge of the trolley track. The cleaning trolley includes a roller support, a roller, and a cleaning blade. The roller is rotatably mounted on both sides of the roller support via a rotating shaft. The roller has a V-groove that engages with the corresponding limiting strip. The cleaning blade is mounted on the roller support.

[0007] Furthermore, the cleaning blade includes a blade holder, a furnace door brick scraper, and a web scraper. The furnace door brick scraper is mounted on the blade holder, and a first bending plate is integrally formed at one end of the blade holder. The web scraper is mounted on the first bending plate.

[0008] Furthermore, the furnace door brick scraper is a hollow structure formed by four furnace door brick scraper plates. The first furnace door brick scraper plate is mounted on the cutter holder via a furnace door brick scraper plate mounting bracket. The second furnace door brick scraper plate is arranged opposite to the first furnace door brick scraper plate, and there is an included angle between the second furnace door brick scraper plate and the first furnace door brick scraper plate, so that the second furnace door brick scraper plate can fit against the surface of the furnace door brick of the coke oven door.

[0009] Furthermore, the upper and lower edges of the second furnace door brick scraper and the belly plate scraper are both horizontally equipped with blades.

[0010] Furthermore, the pressure-bearing regulating device includes a first pressure-bearing connecting seat, a second pressure-bearing connecting seat, and a buffer. The first pressure-bearing connecting seat is mounted on the frame, the second pressure-bearing connecting seat is mounted on the side of the closed track near the frame, one end of the buffer is hinged to the first pressure-bearing connecting seat, and the other end is hinged to the second pressure-bearing connecting seat.

[0011] Furthermore, the locking head includes two relatively bent second bending plates, a first pin connecting the two second bending plates, and a locking rod connecting the two second bending plates. The length of the first pin is longer than that of the locking rod, and a locking groove is formed between the locking rod and the two bending plates.

[0012] Furthermore, the positioning and locking device also includes a first hinge support, a second hinge support, and a connecting plate. The first hinge support is mounted on the slide plate, one end of the locking cylinder is hinged to the first hinge support, and the other end of the locking cylinder is hinged to the second hinge support. The second hinge support is mounted on the first guide frame, and the connecting plate is connected to the first guide frame. Two second limiting plates are mounted on the connecting plate. The slide plate has guide holes along the sliding direction of the slide plate, and the second hinge support is located in the guide holes.

[0013] Furthermore, the positioning and locking device also includes a second guide frame, which is parallel to the first guide frame. The second guide frame is mounted on the frame, and the slide plate is slidably mounted on the second guide frame.

[0014] Furthermore, an external connector is mounted on the frame, which is used to mount the frame onto an external moving device.

[0015] Advantages and positive effects of the present invention: The positioning and locking device of this invention drives a sliding plate along a guide frame via a locking cylinder. Through the engagement of a first limiting hole and a second pin, and vice versa, the linear motion of the sliding plate is converted into the rotational motion of the locking head, achieving simultaneous alignment and locking of the coke oven door by the locking heads on both sides. This structure effectively solves the positioning deviation problem caused by the lack of an alignment and locking mechanism in existing devices, preventing relative movement between the device and the oven door during cleaning, and improving the stability and efficiency of the cleaning operation.

[0016] This invention utilizes the meshing transmission of a drive motor's gear and rack to propel the cleaning trolley in a complete closed-loop motion along a closed track. This enables the cleaning trolley to thoroughly clean the area to be cleaned at the coke oven door. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] This invention provides a coke oven door cleaning device based on electric motor drive, such as... Figure 1-2 As shown, it includes a frame 1, a closed track 2, a cleaning trolley 3, a drive unit 4, a pressure-bearing adjustment device 5, and a positioning and locking device 6. The locking devices are installed in pairs, opposite each other on both sides of the frame corresponding to the coke oven door.

[0033] An external connecting seat 8 is installed on the frame 1, which is used to install the frame 1 on an external moving device. The closed track 2 is vertically installed inside the frame 1 through a pressure-bearing adjusting device 5, and the cleaning trolley 3 is slidably installed on the closed track 2.

[0034] like Figure 1 , Figure 9 and Figure 11 As shown, the drive device 4 includes a drive motor 40, a rack 41, a gear 42 and a connecting base 46. The rack 41 is installed on the front and rear sides of the closed track 2, the gear 42 is installed on the output end of the drive motor 40, and the gear 42 meshes with the rack 41. The connecting base 46 is located on the side of the rack 41 away from the gear 42 and is connected to the sweeping cart 3.

[0035] like Figure 6-8 As shown, the positioning and locking device 6 includes a sliding plate 22, a locking cylinder 23, a first guide frame 24, and a locking head 25. The first guide frame 24 is installed on the frame 1 of the coke oven door cleaning device. The sliding plate 22 is slidably installed on the first guide frame 24. First limiting plates 26 are provided on both sides of the sliding plate 22. The first limiting plates 26 are provided with strip-shaped first limiting holes 27 perpendicular to the moving direction of the sliding plate 22. One end of the locking cylinder 23 is installed on the sliding plate 22, and the other end of the locking cylinder 23 is installed on the first guide frame 24. The first guide frame 24 connects two second limiting plates 28. The second limiting plates 28 are provided with strip-shaped second limiting holes 35 perpendicular to the first limiting holes 27. The locking head 25 is provided with a second pin 29 and a first pin 37 corresponding to the first limiting holes 27 and the second limiting holes 35, respectively. There is a certain radial distance between the first pin 37 and the second pin 29.

[0036] The locking head 25 includes two relatively bent second bending plates 36, a first pin 37 is connected between the two second bending plates 36, and a locking rod 38 is also connected between the two second bending plates 36. The length of the first pin 37 is longer than that of the locking rod 38, and a locking groove 39 is formed between the locking rod 38 and the two bending plates 17.

[0037] The positioning and locking device 6 also includes a first hinge support 30, a second hinge support 31, and a connecting plate 32. The first hinge support 30 is mounted on the slide plate 22. One end of the locking cylinder 23 is hinged to the first hinge support 30, and the other end of the locking cylinder 23 is hinged to the second hinge support 31. The second hinge support 31 is mounted on the first guide frame 24. The connecting plate 32 is connected to the first guide frame 24. Two second limiting plates 28 are mounted on the connecting plate 32. The slide plate 22 has guide holes 33 along the sliding direction of the slide plate 22, and the second hinge support 31 is located in the guide holes 33. It also includes a second guide frame 34, which is parallel to the first guide frame 24 and is mounted on the frame 1. The slide plate 22 is slidably mounted on the second guide frame 34.

[0038] like Figure 2-3 As shown, the closed track 2 includes two oppositely arranged track supports 9 of the same shape. The track supports 9 are rectangular and have rounded corners. A trolley track 10 is provided on one side opposite to the two track supports 9. A limiting strip 11 with a triangular cross section is provided inward along the opening edge of the trolley track 10. The cleaning trolley 3 includes a roller support 12, a roller 13 and a cleaning blade. The roller 13 is rotatably mounted on both sides of the roller support 12 via a rotating shaft. The roller 13 is provided with a V-groove 14, which engages with the corresponding limiting strip 11. The cleaning blade is mounted on the roller support 12.

[0039] like Figure 4-5 As shown, the cleaning blade includes a blade holder 15, a furnace door brick scraper 16, and a belly plate scraper 18. The furnace door brick scraper 16 is mounted on the blade holder 15. One end of the blade holder 15 is integrally formed with a first bending plate 17, and the belly plate scraper 18 is mounted on the first bending plate 17.

[0040] The furnace door brick scraper 16 is a hollow structure formed by four furnace door brick scraper plates, allowing the material scraped off by the scraper 16 to fall directly through the hollow, preventing impurities from adhering to the blades. The first furnace door brick scraper plate 19 is mounted on the cutter holder 15 via a furnace door brick scraper plate mounting bracket 21. The second furnace door brick scraper plate 20 is positioned opposite the first furnace door brick scraper plate 19, and an angle exists between them, allowing the second furnace door brick scraper plate 20 to fit snugly against the surface of the furnace door brick. Both the second furnace door brick scraper plate 20 and the web scraper 18 have horizontally arranged blades along their upper and lower edges.

[0041] like Figure 10 As shown, the pressure-bearing regulating device 5 includes a first pressure-bearing connecting seat 43, a second pressure-bearing connecting seat 44, and a buffer 45. The first pressure-bearing connecting seat 43 is mounted on the frame 1, the second pressure-bearing connecting seat 44 is mounted on the side of the closed track 2 near the frame 1, one end of the buffer 45 is hinged to the first pressure-bearing connecting seat 43, and the other end is hinged to the second pressure-bearing connecting seat 44.

[0042] Working principle: Using the external connecting seat 8 on frame 1, the cleaning device is installed and fixed on the external moving device. The external moving device drives the cleaning device to the corresponding position of the coke oven door to be cleaned, completing the initial alignment.

[0043] The positioning and locking device 6 is activated, and the locking cylinder 23 drives the sliding plate 22 to slide linearly along the first guide frame 24 and the second guide frame 34. When the sliding plate 22 moves, it simultaneously drives the first limiting plates 26 on both sides to move. At the same time, the second pin 29 of the locking head 25 moves along the strip-shaped first limiting hole 27 of the first limiting plate 26, and the first pin 37 of the locking head 25 moves along the strip-shaped second limiting hole 35 of the second limiting plate 28. Due to the radial distance between the first pin 37 and the second pin 29, the linear motion of the sliding plate 22 is converted into the rotational motion of the locking head 25, thereby causing the locking grooves 39 of the locking head 25 on both sides of the coke oven door to engage with the original protrusions on both sides of the coke oven door, realizing the alignment and locking of the cleaning device and the oven door.

[0044] During the alignment and locking process, the extension and retraction adjustment of the buffer 45 can drive the closed track 2 to make slight adjustments to its vertical posture around the hinge point, avoiding damage caused by rigid alignment between the cleaning device and the furnace door; at the same time, the buffer 45 can effectively absorb the vibration generated during the cleaning process, further improving the stability of the device.

[0045] Start the drive unit 4, the output end of the drive motor 40 rotates and drives the gear 42 to rotate. Using the gear and rack transmission principle, the sweeping trolley 3 is driven to make a periodic closed-loop motion along the rack through the connecting base 46.

[0046] During the movement of the cleaning trolley 3, the furnace door brick scraper 16 on the blade holder 15 cleans the furnace door brick area, while the web scraper 18 installed on the first bending plate 17 cleans the furnace door web area. The horizontal blades at the upper and lower edges of both ensure that the blades are only subjected to vertical force, thus improving the service life of the scrapers. The number of cleaning trolleys 3 can be flexibly increased or decreased according to the actual size of the furnace door to improve cleaning efficiency.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
