The work vehicle can run on two or more rails provided on the furnace so as to extend in a direction in which the carbonization chambers and the combustion chambers are alternately arranged, and at a predetermined position along the rails. It turns so that it may become substantially parallel to a rail, and it is comprised so that it can pass the said opening part, It is characterized by the above-mentioned.
[0010]
In the case of the device according to the present invention, in addition to being able to travel along the rail, the work vehicle is configured to turn at a predetermined position along the rail so as to be substantially parallel to the rail and pass through the opening. Therefore, it becomes possible not to interfere with the running of the loading vehicle.
[0011]
The work vehicle, as in claim 2, includes a frame having a length straddling the rail, a maintenance work executing means provided on the frame, for performing the maintenance work, and rotatably supported by the frame.

The suspension means is in a state in which the tip hook is in the first posture and the extension hook is contracted. Horizontal When the angle is adjusted and the moving member moves to the end of the frame, a standby state in which the moving member is folded along the length of the frame and within the length thereof, the leading edge is set in the second posture, and the expansion and contraction is It can be set as the structure which can be deform | transformed into the use condition spread | expanded to a general reverse L shape by adjusting the angle vertically.
[0017]
In the case of this configuration, the suspension means is adjusted along the frame by adjusting the angle in the horizontal direction in a state in which the tip collar is in the first posture and the telescopic collar is contracted, and the moving member moves to the end of the frame. A standby state that is folded in the length direction, and a use state in which the tip heel is in the second posture and the telescopic heel is vertically angle-adjusted to be widened in an approximately inverted L shape. Since it can be deformed, it can be used in a widely expanded state or in a standby state where it is folded small.
[0018]
The work vehicle is configured such that an outer dimension in a direction across the frame in the standby state is relatively smaller in each direction than an opening of the charging vehicle, as in claim 6. It is preferable to do.
[0019]
In the case of this configuration, the work vehicle can pass under the charging vehicle, and the work vehicle can be moved onto the furnace on the opposite side across the charging vehicle. Therefore, since it becomes possible to move the work vehicle to the opposite side of the charging vehicle from one of the two furnace areas divided by the charging vehicle to the other without using a crane or a tow truck, It is possible to prevent the operation rate of the coke oven from being lowered without waiting for the charging vehicle, that is, without temporarily stopping the operation.
[0020]
In the working device in the coke oven according to the present invention, the rail may serve as a rail for running the charging vehicle.

[0036]
7 is a front view showing the vicinity of the moving member 23, and FIG. 8 is a plan view thereof.
[0037]
The moving member 23 has a moving carriage 232 provided with four third wheels 231 that rotate on the frame 10 (see FIGS. 2 and 7). In addition, the mobile carriage 232 is provided with four fourth wheels 233. The fourth wheel 233 is configured to abut on a plate material 234 provided on the lower surface of the upper flange of the steel material 10a constituting the frame 10 (see FIGS. 4 and 7). The wheels 233 prevent the mobile carriage 232 from being lifted. In addition, fifth wheels 235 that rotate about the vertical axis are attached to four locations on the lateral side of the plate member 234 (see FIG. 9), and the movable carriage 232 is moved in the left-right direction by these fifth wheels 235. Swing is prevented. Therefore, when the third wheel 231 is driven to rotate, the movable carriage 232 moves reliably along the frame 10.
[0038]
The base end rod 241 is supported in a state in which a horizontal shaft 237 attached to the base end portion can swing on the moving member 23 via a means (not shown). In addition, a cylinder rod 243a of a swing cylinder 243 provided so as to be swingable within a predetermined angle range around a horizontal axis is attached to a base end portion of the base end rod 241. The cylinder rod 243a is advanced and retracted. The angle of the base end rod 241 can be adjusted horizontally and vertically by turning on and swinging the swing cylinder 243. In this embodiment, the base end rod 241 is set to be vertical in the use state A and to be horizontal in the standby state B. The
[0039]
Further, a rotation driving means is provided at the base end portion of the base end rod 241. As shown in FIG. 10, the rotation driving means has an external gear 244 attached concentrically with the base end flange 241. The external gear 244 meshes with a gear 246 attached to a rotation shaft of a motor 245 provided at a base end portion of the base end rod 241, and the base end rod 241 is driven to rotate around the axis. It is like that.
[0040]
As shown in FIG. 11, the advancing / retreating mechanism of the slide rod 242 with respect to the base end rod 241 includes a ladder member 247 (not shown in FIG. 2) provided on the side surface of the slide rod 242 and a predetermined height position of the base end rod 241. And two gears 248 provided to be rotationally driven. Note that the gears 248 are arranged at different height positions.
[0041]
The ladder member 247 has a large number of transverse members 247a spanned between two long bars. When the gear 248 rotates in the forward direction, the transverse member 247a with which the teeth engage is drawn out and the slide rod 242 is removed. When the gear 248 is advanced and rotated in the opposite direction, the transverse member 247a with which the teeth are engaged is retracted to retract the slide rod 242, whereby the total length of the telescopic rod 24 can be adjusted. Note that a guide roller 249a, an auxiliary support roller 249b, and a track correcting roller 249c for guiding the advancement and retreat of the slide rod 242 are provided at predetermined positions on the base end rod 241 (see FIG. 2). 2 and 11, 241 a is a stopper provided on the base end rod 241 and receives the base end of the slide rod 242.
[0042]
The tip rod 25 is supported at the tip of the telescopic rod 24, specifically, at the tip of the slide rod 242 so as to be able to swing around the horizontal axis 251 as shown by a one-dot chain line in FIG. The tip flange 25 is changed in posture between a first posture C along the slide rod 242 and a second posture D substantially orthogonal to the slide rod 242. This posture change is performed in the standby state B of FIG. Specifically, it is performed by changing the angle on the horizontal plane with a driving force by an operator or the like in a state in which the telescopic rod 24 is tilted sideways and the tip rod 25 is in the horizontal direction. The first posture C is taken in the standby state B, and at this time, the leading edge 25 is held in the first posture C by a holding member (not shown) provided on the slide rod 242. On the other hand, the second posture D is adopted in the use state A. At this time, as shown in FIGS. 12B and 12C, the side surface 25a of the tip collar 25 is brought into contact with the contact portion 242a provided on the slide collar 242. The leading edge 25 is held in the second posture D by contact.
[0043]
Therefore, the suspending means 22 causes the tip heel 25 and the telescopic fold 24 to be moved to the frame 10 by causing the tip heel 25 to be in the first posture C along the telescopic fold 24 and contracting the telescopic fold 24 in parallel with the frame 10. Can be done in parallel. Then, by moving the moving member 23 to the end of the frame 10, it is possible to enter the standby state B in which the tip rod 25 and the expansion rod 24 are arranged on the frame 10 without jumping out from the end of the frame 10. Become. The tip heel 25 is designed to be shorter than the minimum length of the telescopic heel 24, and the minimum length of the telescopic heel 24 is designed to be shorter than the length of the frame 10. Further, as the standby state B is entered or after the standby state B is entered, the wire 27 is wound and shortened.
[0044]
By reversing the above, the state of use A is changed. In other words, the wire 27 is rewound to be in a free state, and the tip rod 25 in the first posture C is rotated on the horizontal plane with respect to the telescopic rod 24 to be in the second posture D. Thereafter, the telescopic rod 24 is raised so as to be perpendicular to the frame 10, and then the slide rod 242 is extended by a desired length.
[0045]
Further, in this usage state A, the distance between the lower end of the maintenance work execution member 21 and the furnace top can be adjusted by adjusting the length of the telescopic rod 24 and adjusting the winding length of the wire 27.
[0046]
A total of four outriggers 19 are detachably provided on both sides in the width direction of the frame 10 in the vicinity of both ends in the movement direction of the movable carriage 232 (see FIGS. 3 and 13). As shown in FIGS. 4, 7, 8, and 13, each outrigger 19 includes a horizontal bar 19a having one end detachably attached to a mounting hole 232a provided in the movable carriage 232, and the other end of the horizontal bar 19a. The vertical bar 19b is detachably attached to the lower side. For example, when changing from the use state A to the standby state B or from the standby state B to the use state A, the vertical bar 19b is assembled in an inverted L shape. The lower end is used so as to stand on the upper surface of the coke oven 100. This standing state prevents the work vehicle 3 from falling in the width direction of the frame 10. In the standby state B, the outrigger 19 is removed from the frame 10, and in the use state A, the outrigger 19 is assembled in an inverted L shape.
[0047]
FIG. 14 is a diagram illustrating an example of the shape and dimensions of the opening 111 of the charging vehicle 110. In the illustrated example, the opening 111 has a substantially U-shape in which the lower end of the loading vehicle 110 is recessed upward, and is formed in a stepped shape with a wide lower side and a narrow upper side. W1 is 1040 mm, the lower opening width W2 is 1100 mm, the opening height H1 is 1880 mm, and the height H2 of the stepped portion existing between the lower side and the upper side is 1250 mm.
[0048]
With respect to the opening 111, the work vehicle 3 is designed such that the outer dimensions in each direction across the frame 10 in the standby state B are relatively small. The opening shown in FIG. 14 is an example, and the external dimensions of the work vehicle 3 in the standby state B are designed so that the work vehicle 3 can pass with respect to the shape and dimensions of the opening. Alternatively, when the opening can be changed and the corresponding portion of the opening is smaller than the external dimensions, the shape or size of the opening may be changed.
[0049]
Therefore, in the case of using the working device 1 in the coke oven according to the present embodiment configured as described above, when it is necessary to move the charging vehicle 110 to the opposite side across the work vehicle 3, Before the movement of the charging vehicle 110, the frame 10 travels along the rail 2 by the rotation of the wheel 11 so as to reach a predetermined position, in this embodiment, the upper position of the structure. Thereafter, when the wheel 11 is lifted from the rail 2 by the levitation / turning means 12 on the structure, the frame 10 can be turned. Specifically, the turning assist means 15 assists the turning of the frame 10 by causing the wheel 11 to float from the rail 2 by the operation of the cylinder 14 and applying a turning force to the frame 10 by, for example, an operator or the like. Thus, the frame 10 turns easily. Then, the frame 10 is levitated and swiveled substantially parallel to the rail 2, and moved to a position through which the opening 111 passes by the moving means 18. By this movement, the work vehicle 3 can be passed through the opening 111, so that it is possible not to obstruct the travel of the loading vehicle 110.
[0050]
In addition, the suspension means 22 in the work vehicle 3 of the present embodiment is adjusted in the horizontal angle with the tip rod 25 in the first posture C and the telescopic rod 24 contracted, and the moving member 23 is mounted on the frame 10. By moving to the end, the stand-by state B is folded in the direction along the frame 10 and within the length thereof, and the tip rod 25 is set to the second posture D, and the telescopic rod 24 is vertically adjusted in angle. Therefore, it is possible to change to the use state A that is broadened in an approximately inverted L shape, so that the use state A can be made to be greatly widened, or the standby state B can be made into a small folded state. The work vehicle 3 is designed so that the outer dimensions in the direction across the frame 10 in the standby state B are relatively smaller in each direction than the opening 111 of the charging vehicle 110. Can pass under the charging vehicle 110, and the work vehicle 3 can be moved onto the coke oven on the opposite side across the charging vehicle 110 until then. Therefore, it is possible to move the work vehicle 3 to the opposite side of the loading vehicle 110 from one of the two furnace areas divided by the loading vehicle 110 to the other without using a crane or a tow truck. Therefore, it is possible to prevent the operating rate of the coke oven 100 from being lowered without waiting for the charging vehicle, that is, without temporarily stopping the operation.
[0051]
Moreover, in this embodiment, since the rail 2 can serve as the rail which makes the charging vehicle 110 drive | work, the charging vehicle 110 and the work vehicle 3 can be drive | worked by the common rail 2, Therefore, the rail for charging vehicles Is already provided, it is not necessary to newly provide a rail for the work vehicle, it is possible to simplify the top of the coke oven, and it can be dealt with by producing only the work vehicle.
[0052]
Further, depending on the extension length of the expansion rod 24, by setting the extension length as shown in E or F of FIG. 1, the gas discharge unit 112 on the left side of the coke oven 100, the power supply device 113 on the right side, and the end portion on the right side. Even if it is provided so as to cover the upper side of the combustion chamber located, it can be designed so that the lower end of the maintenance work execution member 21 moves above the gas discharge unit 112 and the power feeding device 113, and is positioned at the end. Maintenance work can be easily performed for the combustion chamber.
[0053]
In the above-described embodiment, a winch is provided on the base end rod as the maintenance work execution means, and the middle of the wire is configured to hang on a pulley provided on the tip end of the distal end rod, but the present invention is not limited thereto, It is good also as a structure which provided the winch directly in the front-end | tip of a front end rod, and abbreviate | omitted the pulley.
[0054]

However, the present invention is not limited to this, and there are two or more structures (alternating carbonization chambers and combustion chambers). Can be similarly applied to a coke oven provided with three or more portions in a lump.
[0055]
In the above-described embodiment, the work vehicle is turned at a position on the structure. However, the present invention is not limited to this, and the furnace strength in a portion other than the structure of the coke oven is higher than a predetermined strength. In some cases, the work vehicle may be turned in a portion other than the structure.
[0056]
Furthermore, although the charging vehicle is applied to one coke oven in the above-described embodiment, the present invention is not limited to this, and can be applied to a coke oven provided with two or more charging vehicles. In this case, when the shape and size of the opening of each charging vehicle are different, the external dimensions in each direction across the work vehicle frame are set with respect to the narrowest or the most dimensionally limited opening. do it.
