Description

  The present invention relates to a coke guide wheel that guides a coke cake that is extruded during a coke cake extrusion operation of a coke oven to a fire extinguisher.

The coke guide car is a moving machine having a guide function for guiding red hot coke from the coke oven to the fire extinguisher.
FIG. 20 is an explanatory diagram of a coke guide car described in Patent Document 1. A coke cake extrusion operation in the coke guide wheel and the coke oven will be described with reference to FIG.
In general, as shown in FIG. 20, the coke cake extrusion operation of the coke oven is provided with a coke guide wheel 52 that can run along the furnace row on the fire extinguisher side of the coke oven 51, and the fire extinguisher at a lower level. 53 is provided so as to be able to run in parallel with the coke guide wheel 52, and an internal coke cake is extruded from the kiln mouth 51 b for each kiln 51 a of the coke oven 51 by an extruder (not shown) provided on the opposite side thereof. The coke cake is introduced into the fire extinguisher 53 through the guide cage 52a of the coke guide car 52 stopped facing the kiln 51b, and is carried by the fire extinguisher 53 to the fire extinguishing tower.

  During such a coke cake extrusion operation, a large amount of gas or dust is generated when coke cake extrusion from the coke oven 51 or when the extruded coke cake is put into the fire extinguisher 53. For this reason, facilities for collecting the generated gas and dust and collecting the dust are provided.

  Such a dust collection facility is roughly composed of two facilities. One of the facilities is a dust collection duct 54 that is provided over the traveling rail of the cork guide wheel 52 along the traveling direction of the cork guide wheel 52 and is installed on the ground at the end of the dust collection duct 54. A dust collector with a suction blower (not shown) is provided. A number of connection ports 55 with normally closed open / close dampers (not shown) are provided on the lower surface of the dust collection duct 54 at regular intervals in the longitudinal direction (corresponding to the respective carbonization chambers).

  The other dust collecting equipment is provided on the side of the cork guide wheel, and is a large dust collecting hood 56 provided integrally with the cork guide wheel 52 protruding from the cork guide wheel 52 to above the fire extinguisher 53. . A connecting duct 57 having an expandable inner / outer double pipe structure projects from the upper portion of the dust collecting hood 56, and a movable outer cylinder 57b that can move forward and backward with respect to the fixed inner cylinder 57a is a drive mechanism such as a hydraulic cylinder. By being advanced upward by 58, this upper end comes into contact with the connection port 55 of the dust collection duct 54. After the contact, the normally closed opening / closing damper of the connection port 55 can be opened by another driving device (not shown).

In the coke oven dust collection equipment configured as described above, a large amount of dust generated from the coke guide wheel 52 in the vicinity of the fire extinguisher when the coke cake is pushed out in the coke oven 51 is collected by the dust collecting hood 56 and connected. The dust is sucked from the duct 57 through the dust collecting duct 54 and collected.
JP-A-63-81197

  However, the cork guide wheel 52 shown in Patent Document 1 has the following problems because the dust collection hood 56 is provided integrally with the coke guide wheel 52. Since this problem is related to the operation of the coke guide wheel 52 during the coke cake pushing operation, the operation of the coke guide wheel 52 during the coke cake pushing operation will be described first.

The operation of the main coke guide wheel 52 associated with the coke cake extrusion operation is to move the coke guide wheel 52 in the direction of the furnace group, stop at the position of the kiln 51a where the coke cake extrusion is performed, remove the furnace lid 61, and perform the coke cake extrusion. And after the coke cake extrusion is completed, the furnace lid 61 is attached.
In order to perform such an operation, the coke guide wheel 52 guides the coke cake to be pushed out to the fire extinguisher 53 by the lid attaching / detaching device 63 having a function of removing and holding the furnace cover 61 and attaching the furnace cover 61b to the kiln 51b. In view of the function of the device, these devices are arranged back and forth in the direction of movement of the coke guide wheel 52 (see FIG. 21).

FIG. 21 is an explanatory diagram for explaining the series of operations described above in the coke guide wheel 52, and is a diagram schematically showing a state in which the coke oven 51 and the coke guide wheel 52 are viewed in plan view. In FIG. 21, (a) to (c) show main operation states in the order of the operation flow.
Hereinafter, the operation of the coke guide wheel 52 during the coke cake extrusion operation will be described with reference to FIG.

  The coke guide wheel 52 is caused to travel so as to coincide with the core of a predetermined kiln 51a and stop. After the lid attaching / detaching device 63 is moved forward to the furnace side to support the lift of the furnace lid 61, it is moved backward and further rotated (see FIG. 21A). In this state, the coke guide wheel 52 is moved along the track to align the lattice device 65 with the kiln opening 51b from which the furnace cover 61 has been removed. The lattice device 65 is moved forward toward the kiln opening 51b and fixed in position. In this state, the coke cake 66 is pushed out (see FIG. 21B). After completion of the work, the lattice device 65 is moved backward. Thereafter, the kiln mouth 51b is cleaned, and the coke guide wheel 52 is moved again along the track to align the lid attaching / detaching device 63 with the kiln mouth 51b, and then is turned toward the kiln mouth 51b to be further advanced. The furnace lid 61 is attached (see FIG. 21C).

  As described above, in the coke cake extrusion operation, the coke guide wheel 52 is first stopped at the lid removal position, then moved to the coke cake extrusion position, and again moved to the lid attachment position that is the same position as the lid removal position. Movement is necessary. For this reason, when the dust collection hood 56 and the dust collection duct 54 are connected via the connection duct 57 when the coke guide wheel 52 is moved to the lid removal position, the dust collection hood 56 is integrally provided in the coke guide wheel 52. Therefore, the subsequent movement cannot be performed. In order to move, it is necessary to once disconnect the connection duct 57 and the dust collection duct 54, specifically, as follows.

  First, when the coke guide wheel 52 is moved to the cover removal position, the dust collection hood 56 and the dust collection duct 54 are connected. When moved to the position, the dust collecting hood 56 and the dust collecting duct 54 are connected again. Then, when the coke cake extrusion is finished, the dust collecting hood 56 and the dust collecting duct 54 are disconnected.

Thus, in the conventional coke guide wheel 52, in a series of work steps related to coke cake extrusion, the dust collection hood 56 and the dust collection duct 54 must be connected and disconnected repeatedly, and the operation of the apparatus becomes complicated. There is a problem that the cycle time of work is extended. Moreover, since the connection between the dust collection hood 56 and the dust collection duct 54 is disconnected during a series of operations relating to coke cake extrusion, there is also a problem that dust collection cannot be performed sufficiently when the connection is performed.
Note that the connection before the lid removal operation and the disconnection immediately after the lid removal operation are complicated, and therefore the connection between the dust collection hood 56 and the dust collection duct 54 is performed by pushing the coke guide wheel 52 through the coke cake extrusion. Although it is conceivable to perform the operation only when it is moved to the position, if it does so, there is a problem that the collection of gas and dust generated in large quantities at the time of removing the furnace lid becomes insufficient and the environment deteriorates.

  The coke guide wheel 52 shown in Patent Document 1 is of a type that cantilever-supports a dust collection hood 56 as shown in FIG. In addition to the one that supports the dust collection hood in a cantilever manner in this way, there are types that support the tip of the dust collection hood with wheels. Needless to say, the cork guide wheel has the above-mentioned problems as long as it is integrally provided.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a coke guide car that can reliably collect dust over the entire process of coke cake extrusion without extending the cycle time of the work. It is said.

  Note that the actual dust collecting hood 13 is manufactured by assembling a framework with a steel frame or the like and installing a steel plate formed in a duct shape on the framework, but the framework member is omitted in FIG.

<Connecting means>
The connecting means 17 has a function of connecting the dust collecting hood 13 together with the guide wheel main body 11 and separating the guide wheel main body 11 and the dust collecting hood 13 by disconnecting the connection.
As shown in FIG. 2, two pairs of connecting means 17 are provided on the upper surface of the guide wheel main body 11 so as to sandwich the support portion 25 of the dust collecting hood 13 from the front-rear direction (furnace group direction).
As shown in FIG. 3, the connecting means 17 restrains the dust collecting hood 13 by sandwiching the front and rear end portions of the support portion 25 from the outside, so that the dust collecting hood 13 is connected during the connecting operation. The guide vehicle main body 11 is prevented from moving in any direction.

FIG. 4 is an enlarged view of a portion A surrounded by a circle in FIG. The detail of the connection means 17 is demonstrated based on FIG.
The connecting means 17 includes a hydraulic cylinder 35 including a cylinder rod 33 that expands and contracts in the front-rear direction, and a rotating member 37 that rotates as the cylinder rod 33 expands and contracts. The rear end of the hydraulic cylinder 35 is pin-coupled to the guide wheel main body 11 side, and is installed so as to be rotatable about the pin at the rear end.
The rotating member 37 has a first arm 39, a rotating shaft 41, and a second arm 43. The tip of the cylinder rod 33 is connected to one end of the first arm 39, and the first arm 39 rotates around the rotation shaft 41 as the cylinder rod 33 expands and contracts.

As shown in FIG. 4, when the cylinder rod 33 is extended, the contact plate 45 contacts the front and rear walls of the support portion 25, and when the cylinder rod 33 is contracted, as shown by a two-dot chain line in the figure. The plate 45 is separated from the wall of the support portion 25 and the dust collection hood 13 can be moved.

  When the dust collecting hood 13 and the guide wheel main body 11 are connected by driving the hydraulic cylinder 35 of the connecting means 17, the dust collecting hood 13 needs to be in a predetermined position with respect to the guide wheel main body 11. . Therefore, a position detector for detecting the relative position between the dust collection hood 13 and the guide wheel main body 11 is provided, and the hydraulic cylinder 35 is driven based on the position detection signal of the position detector.

<Description of operation>
FIG. 5 is an operation explanatory diagram for explaining the operation of the present embodiment. The operation of the present embodiment will be described based on FIG.
The coke guide wheel 1 is run in a state where the dust collecting hood 13 and the guide wheel main body 11 are connected by the connecting means 17, and the position of the lid attaching / detaching device is matched with the core of the kiln for starting the kiln and stopped.
In this state, the connection means 15 is connected to the connection port 9a of the dust collection duct 9. And the clamp apparatus 32 provided in the food | hood part 23 is driven, and the rail 29 is clamped. Further, the hydraulic cylinder 35 of the connecting means 17 is driven to remove the contact plate 45 of the connecting means 17 from the support portion 25 of the dust collecting hood 13 (see FIG. 5A). In this state, the dust collection hood 13 and the guide vehicle main body 11 are completely disconnected from each other, and the two can move relative to each other.

  In this state, the lid attaching / detaching device is advanced to the furnace side to remove the furnace lid, and the removed lid is moved backward while being lift-supported to be further swung. Then, as shown in FIG. 5B, the guide wheel main body 11 is moved leftward in the drawing to align the lattice device with the kiln opening from which the furnace lid has been removed. During the movement of the guide wheel main body 11, the dust collecting hood 13 is separated from the guide wheel main body 11, and the clamp device 32 provided at the lower portion of the hood portion 23 clamps the rail 29. It will not move as you move. Therefore, it is possible to collect dust through the connecting means 15 regardless of the movement of the guide vehicle main body 11.

When the lattice device can be aligned, the lattice device is moved forward toward the kiln and fixed. In this state, the coke cake is pushed out and the lattice device is moved backward after the work is finished. Then, after cleaning the kiln and moving the guide car body 11 again and aligning the lid attaching / detaching device with the kiln, it is turned toward the kiln and further advanced to mount the furnace lid.
When the furnace lid is mounted, it is confirmed that the positions of the guide wheel main body 11 and the dust collecting hood 13 are at predetermined positions based on the position detection signal of the position detector. As shown in FIG. 5C, the abutting plate 45 is brought into contact with the support portion 25 of the dust collecting hood 13 and the clamp of the rail 29 by the clamp device 32 of the hood portion 23 is released. As a result, the dust collection hood 13 and the guide vehicle main body 11 are connected to each other so that they can move together.
In this state, the connection means 15 is removed from the connection port 9a and moved to the position of the kiln where the next kiln is removed. Thereafter, the same operation is repeated.

As described above, according to the present embodiment, since the dust collection hood 13 can be connected to and disconnected from the guide vehicle body 11, the dust collection hood 13 is collected at the initial position of the coke guide vehicle 1. Since it can be connected to the duct 9 and there is no need to disconnect the connection during the subsequent operation, it is possible to continuously collect dust during the operation accompanying the coke cake extrusion without extending the cycle time of the operation.
Further, in the present embodiment, the clamp device 32 is provided at the lower portion of the hood portion 23 and the position of the dust collection hood 13 is fixed. Therefore, after separating the dust collection hood 13 and the guide car body 11, the guide car body The dust collecting hood 13 is not moved when the 11 is moved.

Furthermore, in this embodiment, the dust collecting hood side does not require any driving means, and the structure is simple.
Also, as shown in Fig. 2, the overall length of the coke guide car (length in the furnace group direction) will not be larger than that of the conventional type, so it can be replaced directly with the equipment where the conventional coke guide car is running. Can be installed.

  In the above embodiment, as an example of a connecting means for connecting and disconnecting the dust collecting hood 13 and the guide wheel main body 11, a device in which the front and rear of the support portion 25 of the dust collecting hood 13 are sandwiched from the outside is used. Although mentioned, the aspect of a connection means is not restricted to this. In short, it is sufficient if the dust collection hood 13 and the guide vehicle main body 11 can be connected or disconnected. For example, a pin provided on the guide vehicle body 11 side may be inserted through an insertion hole provided in the support portion 25 of the dust collection hood 13. In other words, an engaging portion is provided on the guide wheel main body 11 side or the dust collecting hood 13 side, and an engaging portion that is engaged with the engaging portion is provided on a side different from that on which the engaging portion is provided. It is only necessary that the part can be engaged and disengaged. And what is necessary is just to be able to move the dust collection hood 13 when the guide vehicle main body 11 is moved in a state where the engaging portion is locked. That is, the connection means includes those having such a function.

  Although not described in detail in the above description, the control means automatically controls the driving of the connecting means 17, the operation of the clamping device 32, the operation of the connecting means 15, etc. based on a position detection signal from a position detector or the like. Is preferable.

[Embodiment 2]
FIG. 6 is an explanatory diagram for explaining the problem to be solved by the second embodiment. The same reference numerals are given to the same parts as those in FIG.
As shown in FIG. 6, the guide car main body 11 is provided with a conveyor 70 for transporting the debris generated during the kiln removal work from the guide car main body 11 and discharging it to the fire extinguisher. The conveyor 70 extends in the direction of the furnace group on the first rail 71 (coke on the coke oven side) side of the guide vehicle main body 11, and then bends on the fire extinguisher side, on the second rail 72 side (rail on the fire extinguisher side). It protrudes outward from the guide wheel main body 11 and extends obliquely upward. A portion extending obliquely upward of the conveyor 70 is disposed adjacent to the side of the dust collection hood 13.
Therefore, when the guide wheel main body 11 moves relative to the dust collection hood 13, there is a risk that the conveyor 70 and the side of the dust collection hood 13 interfere with each other.

As a method for avoiding this, it is conceivable that the portion extending obliquely upward of the conveyor 70 and the dust collecting hood 13 are sufficiently separated from each other so that they do not interfere even when they are closest to each other.
However, if it does in that way, the length of the guide car main body 11 in the furnace group direction will become long, and it will become impossible to apply as it is to the equipment in which the conventional coke guide car is traveling.
Therefore, in the present embodiment, interference between the conveyor 70 and the dust collecting hood 13 can be prevented without increasing the length of the guide vehicle body 11 in the furnace group direction.

7 and 8 are explanatory diagrams for explaining the outline of the present embodiment. In the present embodiment, the shape of the dust collecting hood 13 is such that the upper end portion 13a and the lower end portion 13b extend in the furnace group direction, and the width in the furnace group direction in the middle part 13c in the vertical direction is reduced. An interference prevention mechanism 73 is provided for preventing the conveyor 70 and the dust collection hood 13 from interfering when the dust hood 13 moves relative to the guide vehicle body 11 in the furnace group direction.
The interference prevention mechanism 73 is provided at a part of the dust collection hood 13 that interferes with the conveyor 70, and is capable of rotating toward the inside of the dust collection hood 13 (a hatched portion in FIG. 7), and the dust collection. A link member 77 that rotates the door 75 when the hood 13 moves relative to the guide vehicle body 11 is provided.
FIG. 7 shows a state where the conveyor 70 and the dust collection hood 13 are separated from each other, and FIG. 8 shows a state where the conveyor 70 is located near the dust collection hood 13.
As shown in FIG. 8, when the conveyor 70 approaches the dust collection hood 13, the door 75 provided on the side surface of the dust collection hood 13 rotates inward, and the conveyor 70 interferes with the dust collection hood 13. Without being stored in the dust collection hood 13.

9 to 12 are explanatory views for explaining the interference prevention mechanism 73 in detail. FIG. 9 shows a state in which the conveyor 70 and the dust collecting hood 13 are separated from each other and the door 75 is closed. FIG. 9 shows a cross-sectional view taken along the line BB in FIG. 11 shows a state in which the conveyor 70 and the dust collecting hood 13 approach each other and the door 75 is opened, and the conveyor 70 is accommodated in the dust collecting hood 13. FIG. 12 is a sectional view taken along the line CC in FIG. Is shown.
As shown in FIGS. 10 and 12, the door 75 provided on the dust collection hood 13 constituting the interference prevention mechanism 73 is connected at one end to the wall of the dust collection hood 13 so as to be rotatable. The hood 13 can be turned about 90 degrees toward the inside. One end of the link member 77 is rotatably connected to the central portion of the door 75, and the other end is rotatably connected to the side portion of the conveyor 70.

  The operation of the present embodiment configured as described above will be described with reference to FIG. As shown in FIG. 5 (a), in a state where the position of the lid attaching / detaching device is matched with the core of the kiln for starting the kiln and the coke guide wheel 1 is stopped, the dust collecting hood 13 is placed at the center of the guide wheel main body 11. In this state, the conveyor 70 and the dust collection hood 13 are closest to each other. In this state, as shown in FIGS. 11 and 12, the door 75 rotates inside the dust collection hood 13 and the conveyor 70 is stored inside the dust collection hood 13.

In this state, as described above, the lid attaching / detaching device is advanced to the furnace side to remove the furnace lid, and the removed lid is moved backward while being lift-supported to be further swung. The debris generated during the operation of removing the furnace lid is conveyed by the conveyor 70 and dropped onto the fire extinguisher.
When the furnace cover is removed, the door 75 is opened and the lower side surface of the dust collection hood 13 is open. However, when the furnace cover is removed, dust collection at the upper part of the dust collection hood 13 is mainly performed. Therefore, even if the lower side surface of the dust collection hood 13 is open, the suction / dust collection effect is not impaired.
When the furnace lid is removed, the guide wheel main body 11 is moved leftward in the figure as shown in FIG. 5B, and the position of the lattice device is adjusted to the kiln opening from which the furnace lid has been removed. The conveyor 70 moves away from the dust collecting hood 13 by the movement of the guide vehicle main body 11, but at this time, as shown in FIGS. 9 and 10, the door 75 is pulled by the link member 77 to rotate and close. The side surface of the dust collection hood 13 is closed.

When the alignment of the lattice device is completed, the lattice device is advanced toward the kiln opening to fix the position. In this state, the coke cake is pushed out. The drop generated during the work is conveyed out of the guide car body 11 by the conveyor 70 and dropped onto the fire extinguisher. Dust is generated most at the time of leaving the kiln, but at this time the door 75 is closed and the side surface of the dust collection hood 13 is closed, so the suction effect by the dust collection hood 13 is not reduced, Work is done.
When the kiln removal operation is completed, the kiln opening is cleaned and the guide wheel body 11 is moved again to align the lid attaching / detaching device with the kiln opening. At this time, as shown in FIGS. As the vehicle body 11 moves, the door 75 is opened and the conveyor 70 is accommodated in the dust collection hood 13.

As described above, in the present embodiment, the door 75 is provided on the side wall of the dust collection hood 13, and the door 75 can be opened and closed in conjunction with the relative movement of the conveyor 70 and the dust collection hood 13. Even when the guide wheel main body 11 and the dust collection hood 13 move relative to each other as the dispensing operation progresses, and the conveyor 70 approaches the dust collection hood 13, the interference between the conveyor 70 and the dust collection hood 13 can be prevented. In addition, the mechanism for opening and closing the door 75 has a simple structure and does not require a complicated actuator. Therefore, there is also an effect that the equipment cost of the actuator (including the control system) and the maintenance cost such as maintenance management are not generated. .
In the present embodiment, when the coke cake is pushed out, the door 75 is closed and the side surface of the dust collecting hood 13 is closed. Therefore, the dust collecting during the coke cake pushing operation is performed. The dust collection effect in the hood 13 is not reduced.

With the structure shown in the second embodiment, even if the width of the conveyor 70 is widened, there is no risk of interference between the conveyor 70 and the dust collecting hood 13. Therefore, in order to reliably receive the debris generated at the furnace port, it is preferable to increase the width of the conveyor 70 including not only the portion extending outside the guide wheel main body 11 but also the portion extending in the furnace group direction. .
However, the conventional guide wheel main body 11 has a situation in which the width of the conveyor 70 (see FIG. 6) extending in the furnace group direction within the guide wheel main body 11 cannot be widened due to its framework structure.
Hereinafter, this situation will be described.

FIG. 13 is an explanatory view of a conventional frame structure of the guide vehicle main body 11, FIG. 14 is a sectional view taken along the line DD in FIG. 13, and FIG. 15 is a sectional view taken along the line EE in FIG. Hereinafter, a conventional skeleton structure of the guide vehicle main body 11 will be described with reference to FIGS.
The conventional frame structure of the guide vehicle main body 11 includes a saddle 79 extending over the entire length of the guide vehicle provided with a traveling wheel device in both the first rail 71 (coke oven side rail) and the second rail 72 (fire extinguisher side rail). A plurality of columns 83 that connect the uppermost cross beam 81 and the saddle 79 at appropriate positions on both sides and in the center of the furnace group direction. A mounting device such as a lattice device is supported. Since the mounting device has a considerable weight, the column 83 that supports the mounting device and the saddle 79 that supports the column 83 need to have a corresponding size and strength.

  As described above, the conveyor 70 extending in the direction of the furnace group that receives and transports the debris generated at the furnace port in front of the furnace at the time of removing the furnace lid and at the time of coke extrusion is installed on the furnace side at the lower portion of the guide vehicle main body 11. However, since the width of the saddle 79 located on the first rail 71 side is large, the installation space of the conveyor 70 is restricted, and it becomes difficult to give the conveyor 70 a necessary trough width, and the width becomes narrow. Had to be forced. As a result, unacceptable debris was scattered on the platform, causing problems with the debris disposal.

Therefore, in the third embodiment, in order to widen the conveyor 70 extending in the direction of the furnace group without being restricted by the saddle 79 on the first rail 71 side, the framework structure of the guide wheel main body 11 is changed to the first rail. The saddle 79 on the 71 side can be omitted.
16 is an explanatory view of the framework structure of the guide vehicle main body 11 according to the third embodiment, FIG. 17 is a sectional view taken along line FF in FIG. 16, and FIG. 18 is a sectional view taken along line GG in FIG. 19 is a cross-sectional view taken along line HH in FIG. Hereinafter, the framework structure of the guide vehicle main body 11 according to the present embodiment will be described with reference to FIGS.

In the guide vehicle main body 11 according to the present embodiment, as shown in FIGS. 18 and 19, a diagonal member 85 is provided to connect the lower portion of the support 83 on the second rail 72 side and the uppermost cross beam 81, thereby providing a truss structure. The truss structure is used to support the mounting device. The uppermost cross beam 81 is increased in size in order to have a necessary strength.
By adopting such a structure, a conveyor bracket 87 for supporting the conveyor 70 may be provided at the center in the furnace group direction on the first rail side, and the saddle 79 is not necessary, and as shown in FIG. A conveyor 70 (for example, a wide flat chain conveyor) having a trough width sufficient for receiving a wreck can be easily installed, and a wreckage process can be reliably performed.
