Description

Coke oven door unmanned operation platform device

[0001] The present embodiments relate to a platform device for unmanned operation of a coke oven door that enables unmanned operation during coke oven door operation.

[0002] A coke oven is a device that heats coal to a high temperature to remove impurities and produce high-quality red-hot coke.

[0003] Generally, a coke oven consists of multiple carbonization chambers, and fuel coal is supplied to each chamber through the upper charging port.

[0004] In this process, coal is carbonized at high temperatures for a certain period of time and converted into coke.

[0005] The coke, after carbonization is complete, is discharged through the door of the carbonization room, loaded onto a digester, and transported to the process location.

[0006] During the coke manufacturing process, gaseous impurities such as coke oven gas (COG) are generated inside the carbonization chamber.

[0007] These gases must be confined within the carbonization chamber and not leak to the outside; however, due to the nature of the coke oven, a high-temperature and high-pressure environment persists, so there is a possibility of gas leakage occurring at the upper charging port, extrusion side door, coke side door, etc.

[0008] Such leaks occur more frequently, especially when a large amount of foreign matter (e.g., tar and carbon) adheres to the surface and frame of the door, impairing airtightness.

[0009] Such gas leaks cause various serious problems.

[0010] First, if high-temperature gas leaks outside the facility, it can cause damage and deformation to surrounding equipment.

[0011] Second, the emission of toxic gases not only reduces the safety of the working environment but also intensifies air pollution, exacerbating environmental problems.

[0012] This makes it more difficult to manage air quality and comply with environmental regulations at the factory, and can have an adverse effect on the health of local residents.

[0013] Third, worker safety is also a significant issue. Leaked gas poses serious risks to workers, such as burns, gas poisoning, falls, and entrapment, which are highly likely to lead to industrial accidents.

[0014] Currently, workers are using service carts to travel directly to the gas leak site and are performing sealing work.

[0015] However, this work is extremely dangerous due to risk factors such as high temperatures, toxic gases, and limited workspaces, and is identified as one of the major causes threatening worker safety.

[0016] Therefore, there is a need for the development of technology that can unmanned or automate the operation of coke oven doors and carbonization chambers.

[0017] These embodiments enable coke oven door operation (gas leak prevention operation) to be performed through a robot module, thereby fundamentally preventing the possibility of accidents occurring to workers and significantly improving work speed and work efficiency, and can provide a platform device for unmanned coke oven door operation.

[0018] In one aspect, embodiments provided may provide a platform device for unmanned operation of a coke oven door, characterized by comprising: a plurality of rail support members spaced apart at a position corresponding to the coke oven door, a vertical rail member connected to the rail support members, and a horizontal rail member connected to the bottom surface of the vertical rail member; a saddle member including a driving module member configured to move along the horizontal rail module member; a vertical rail module member connected to the saddle member, positionally variable in the longitudinal direction of the horizontal rail module member, and spaced apart from the saddle member to form a workspace that expands in the vertical direction; a lifting member configured corresponding to the workspace and equipped with a robot module member, which moves in the vertical direction along the vertical rail module member by a driving unit; and a control unit configured to control the movement of the saddle member and the lifting member so that the work position by the robot module member can be adjusted externally.

[0019] According to the embodiments, by enabling coke oven door operation (gas leak prevention operation) to be performed through the robot module, a platform device for unmanned coke oven door operation can be provided that can fundamentally prevent the possibility of accidents occurring to workers.

[0020] In addition, by enabling coke oven door operations (gas leak prevention operations) to be performed through the robot module, it is possible to provide a platform device for unmanned coke oven door operations that can dramatically improve work speed and work efficiency.

[0033] Referring to FIGS. 1 to 6, a platform device for unmanned operation of a coke oven door according to one aspect of the present embodiment comprises: a plurality of rail support members (110) spaced apart at a position corresponding to a coke oven door (D), a vertical rail member (120) connected to the rail support members (110), and a horizontal rail member (130) connected to the bottom surface of the vertical rail member (120); a saddle member (200) including a driving module member (210) configured to move along the horizontal rail module member (100); and a vertical rail module member (300) connected to the saddle member (200), positionally variable in the longitudinal direction of the horizontal rail module member (100), and spaced apart from the saddle member (200) to form a workspace (S) that extends in the vertical direction. It is characterized by including: a lifting unit (400) that is provided corresponding to a workspace (S) and is provided with a robot module (410), and moves vertically along a vertical rail module (300) by means of a driving unit (420); and a control unit (500) that controls the movement of the saddle unit (200) and the lifting unit (400) so that the work position by the robot module (410) can be adjusted externally.

[0034] A coke oven is a device that heats coal to a high temperature to remove impurities and produce high-quality red-hot coke.

[0035] Generally, a coke oven consists of multiple carbonization chambers, and fuel coal is supplied to each chamber through the upper charging port.

[0036] In this process, coal is carbonized at high temperatures for a certain period of time and converted into coke.

[0037] The coke, after carbonization is complete, is discharged through the door of the carbonization room, loaded onto a digester, and transported to the process location.

[0038] During the coke manufacturing process, gaseous impurities such as coke oven gas (COG) are generated inside the carbonization chamber.

[0039] These gases must be confined within the carbonization chamber and not leak to the outside; however, due to the nature of the coke oven, a high-temperature and high-pressure environment persists, so there is a possibility of gas leakage occurring at the upper charging port, extrusion side door, coke side door, etc.

[0040] Such leaks occur more frequently, especially when a large amount of foreign matter (e.g., tar and carbon) adheres to the surface and frame of the door, impairing airtightness.

[0041] These embodiments provide a platform device for unmanned coke oven door operation that enables coke oven door operation (gas leak prevention operation), thereby fundamentally preventing the possibility of accidents occurring to workers and significantly improving work speed and work efficiency.

[0042] The platform device for unmanned operation of a coke oven door according to the present embodiment includes a horizontal rail module section (100), a saddle section (200), a vertical rail module section (300), a lifting section (400), and a control section (500).

[0043] The horizontal rail module (100) includes a plurality of rail support sections (110), a vertical rail section (120), and a horizontal rail section (130).

[0044] The rail support section (110) is spaced apart at a position corresponding to the coke oven door (D).

[0045] The rail support section (110) may include a horizontal rail support section (111) and a vertical rail support section (113) that extends vertically from the lower part of the horizontal rail support section (111).

[0046] The rail support section (110) is provided in multiple numbers.

[0047] Among the multiple rail support members (110), the left and right outermost rail support members (110) can each be fixedly supported on the top of a column member (101) that is erected in the vertical direction.

[0048] The vertical rail section (120) is connected to the rail support section (110).

[0049] That is, the vertical rail section (120) can be connected to the vertical rail support section (113) included in the rail support section (110).

[0050] The horizontal rail section (130) is connected to the bottom surface of the vertical rail section (120).

[0051] When viewed from the side, the interconnected horizontal rail section (130) and vertical rail section (120) can have an overall 'T' shape.

[0052] Next, the saddle section (200) includes a driving module section (210) configured to move along the horizontal rail module section (100).

[0053] The driving module (210) may include a pair of first guide wheels (211) that travel along both sides of the vertical rail section (120); a pair of second guide wheels (213) that travel along both upper surfaces of the horizontal rail section (130); a driving wheel (215) that is positioned opposite to the lower part of the second guide wheel (213), is in close contact with the lower surface of the horizontal rail section (130), and is rotated by a driving unit; and a tilting arm (219) that supports the driving wheel (215) rotatably, has one side connected to the saddle section (200) by a hinge (H2), and has the other side elastically supported upward by an elastic structure (217).

[0054] The driving module (210) includes a pair of first guide wheels (211), a pair of second guide wheels (213), a driving wheel (215), and a tilting arm (219).

[0055] The first guide wheel (211) is provided in pairs.

[0056] The first guide wheel (211) travels along both sides of the vertical rail section (120).

[0057] The second guide wheel (213) is provided as a pair.

[0058] The second guide wheel (213) travels along the upper surfaces of both sides of the horizontal rail section (130).

[0059] The drive wheel (215) is positioned opposite the lower part of the second guide wheel (213) and is in close contact with the lower surface of the horizontal rail section (130).

[0060] The drive wheel (215) is driven by rotation by a drive unit (not shown).

[0061] The drive unit (not shown) may be provided as, for example, an electric motor.

[0062] The tilting arm (219) allows the drive wheel (215) to be rotatably supported.

[0063] One side of the tilting arm (219) is connected to the saddle part (200) by a hinge (H2).

[0064] The other side of the tilting arm (219) is elastically supported upward by an elastic structure (217).

[0065] Here, the elastic structure (217) can be provided as, for example, a coil spring.

[0066] Meanwhile, in another embodiment, the saddle section (200) may be configured to include: a first saddle section (200a) comprising a first driving module section (210a) configured to move along a horizontal rail module section (100); and a second saddle section (200b) comprising a second driving module section (210b) configured to move along a horizontal rail module section (100) and connected to one end of the first saddle section (200a) so as to vary the angle within a predetermined range.

[0067] Here, the angle variable structure between the first saddle part (200a) and the second saddle part (200b) can be applied as a structure that rotates within a predetermined interval range around the hinge axis (H1), for example.

[0068] More specifically, the saddle section (200) is configured such that the first saddle body (212a) of the first driving module section (210a) and the second saddle body (212b) of the second driving module section (210b) are configured to move along the horizontal rail module section (100) rotate within a predetermined range around the hinge axis (H1).

[0069] Accordingly, the saddle section (200) is configured such that the angle between the first saddle body (212a) and the second saddle body (212b) is variable around the hinge axis (H1) in response to the bending of the horizontal rail module section (100). Therefore, even if the horizontal rail module section (100) is exposed to high temperatures and bending occurs, the angle between the first saddle body (212a) and the second saddle body (212b) can be flexibly changed, thereby preventing transfer failure.

[0070] Next, the vertical rail module (300) is connected to the saddle (200) and its position is varied along the length of the horizontal rail module (100).

[0071] The vertical rail module (300) forms a workspace (S) that extends vertically, spaced apart from the saddle (200).

[0072] The robot arm of the robot module (410), which will be described later, moves through the workspace (S) toward the coke oven door (D) to perform unmanned work.

[0073] Meanwhile, the vertical rail module (300) may further include solar panels (not shown) installed on one or both sides, and the power produced from the solar panels (not shown) can be stably supplied to each device requiring power.

[0074] Next, the lifting unit (400) is provided to correspond to the workspace (S) and includes a robot module unit (410).

[0075] The lifting unit (400) moves vertically along the vertical rail module (300) by means of the driving unit (420).

[0076] The lifting unit (400) may further include a battery (not shown) that stores power produced from the aforementioned solar panel (not shown), and the power stored in the battery (not shown) supplies power necessary for the operation of the lifting unit (400), and when the battery voltage drops below a certain level, it may be configured to move to a home position and perform automatic power charging.

[0077] The drive unit (420) may be configured to include an electric motor, chain, wire, rack, pinion, etc.

[0078] For example, the drive unit (420) may be composed of a motor and a chain or a rack and pinion for precise position control.

[0079] The lifting unit (400) may include a base frame unit (401); a sliding plate unit (403) which is movably provided on the upper part of the base frame unit (401) and has a robot module unit (410) on its upper part; a driving device (405) which is provided on the base frame unit (401) and provides driving force to the sliding plate unit (403); and a cover unit (407) which is provided on the base frame unit (401) and has the sliding plate unit (403) and the driving device (405) housed inside.

[0080] The lifting unit (400) includes a base frame unit (401), a sliding plate unit (403), a driving device (405), and a cover unit (407).

[0081] The base frame part (401) can move up and down in the vertical direction by riding on the vertical rail module part (300) by means of the aforementioned drive part (including an electric motor, chain, wire, rack, pinion, etc.).

[0082] The sliding plate portion (403) is provided on the upper part of the base frame portion (401) so as to be movable left and right.

[0083] The sliding plate portion (403) may have a rectangular flat plate shape.

[0084] The sliding plate portion (403) can be provided to be slidably movable along a pair of sliding guides (409) provided on the base frame portion (401).

[0085] The driving device (405) is provided in the base frame part (401).

[0088] The cover portion (407) is provided on the base frame portion (401) and accommodates the sliding plate portion (403) and the driving device (405) inside.

[0089] Meanwhile, the lifting unit (400) may further include a temperature and humidity control unit (not shown) that is provided inside the cover unit (407) and controls at least one of the temperature and humidity of the space inside the cover unit (407).

[0090] The temperature and humidity control unit controls the temperature and / or humidity inside the cover unit (407) to be maintained within a certain range so as not to damage the robot module unit (410).

[0091] Next, the control unit (500) controls the movement of the saddle unit (200) and the lifting unit (400) so that the working position by the robot module unit (410) can be adjusted externally.
