Description

  The present invention relates to a suspension balance, a method of moving a coke oven guide wheel (including a mobile device corresponding to the guide vehicle) using a suspension balance, and a method of repairing coke oven equipment using a method of moving a coke oven guide vehicle using a suspension balance. About.

  A coke oven is usually formed of refractory bricks, and is configured such that a plurality of carbonization chambers and combustion chambers partitioned by the walls of the refractory bricks are alternately arranged with their ends aligned in parallel. Coal charged in each carbonization chamber is heated by heat conducted through the wall surface from the combustion chambers arranged on both sides of the carbonization chamber, and coke is generated by dry distillation. An extrusion port is formed on one end surface of each carbonization chamber, and the coke generated in the carbonization chamber is pushed out from the discharge port formed on the other end surface by the extrusion portion of the extruder inserted from the extrusion port. It is. At this time, the extruded coke passes through a guide plate called a guide car grid, is loaded into a fire extinguisher, and is carried to a fire extinguisher or a dry fire extinguishing equipment called CDQ.

  On the upper surface of each carbonization chamber, an inlet for charging coal into the carbonization chamber is formed. The extrusion port and the discharge port can be opened and closed by a furnace lid, and the charging port can be opened and closed by a charging lid. The extruder is disposed on the side of the extrusion port, and rails are laid along the furnace lid of the extrusion port, and can be moved horizontally on the rail. Further, the guide wheel is arranged on the discharge port side, and a rail is laid along the furnace cover, and moves horizontally on the rail. A rail is laid in parallel with the rail of the guide car, and the fire extinguisher moves on this rail. Also, a dust collection duct is usually installed at the upper part of the coke oven on the discharge port to collect dust and soot generated from the kiln and hot air etc. in one place and discharge it to the outside. Ducts and other equipment are collectively projected from the end of the coke oven discharge port toward the top of the guide wheel.

  Since the above-mentioned guide car receives high-temperature coke immediately after being discharged from the carbonization chamber, it is easily damaged and has deteriorated over time. Therefore, it is necessary to update the guide car in conjunction with the repair of the coke oven. Conventionally, when a degraded or damaged part of a guide car is repaired or the guide car itself is updated, the guide car is moved to a sheltered place, that is, a place where coke is not discharged at the coke oven discharge port side. After that, repairs were made at the shelter, and after the guide car was dismantled and removed, a new guide car was assembled.

  However, because it is a coke oven that cannot secure a shelter as described above, or even if there is a shelter, it is close to the coke oven, so it is hot and has a lot of dust. Required several weeks to several months of work time.

  On the other hand, a new guide vehicle is assembled on the ground in advance and trial run, and then installed on the rail for the guide car of the coke oven with a crane or the like. If it can be removed and dismantled on the ground, the guide car can be updated in a short period of time.

  By the way, when a large and heavy suspended load is lifted by a crane or the like, a suspension balance is usually used to stably maintain the posture of the suspended load. For example, in Patent Document 1, a hydraulic cylinder is attached to each corner of a suspension frame of a square suspension balance, and a suspended rope engaged with a tip of a rod of each hydraulic cylinder is connected, whereby a suspended load is transferred by a crane. Lifting is described.

JP 2004-244143 A

  However, when the suspension car described in Patent Document 1 is used to lift the coke oven guide car with a crane, in a normal coke furnace, dust collection ducts, trolley wires, and the like are protruding above the guide car. They become obstacles, and the suspension rope coming out of the suspension balance comes into contact with the obstacles, so the guide car cannot be lifted and cannot be lowered to the ground with a crane. In addition, since the vertical distance between the obstacle and the guide wheel is as narrow as 1.2 to 1.7 m, it is difficult to insert a lifting machine between the obstacle and the guide wheel.

  Accordingly, the present invention provides a suspension balance capable of lifting a coke oven guide wheel even when there is an obstacle such as the dust collection duct, a coke oven guide wheel moving method using the suspension balance, and a coke oven. It aims at providing the repair method of the coke oven equipment using the guide car movement method.

  As a result of intensive studies to solve the above problems, the present inventors have provided a plurality of wires with hydraulic cylinders in the upper part and the lower part, and the upper part and the lower part are connected by a connecting member, or the upper part thereof. By using a suspension balance having a U-shaped vertical cross section that is connected to the lower portion by a connection member provided only on one end side, the recessed portion of the suspension balance is placed above the guide wheel. It has been found that the guide wheel of the coke oven can be lifted by using the protruding obstacles so as to avoid the contact between the obstacles and the suspension rope, and the present invention has been completed.

  Note that the U-shape does not have to be a right angle at each corner forming the dent, and may be a substantially C-shape that bends gently. Moreover, the upper part and the lower part do not need to be the same size, and the connecting member that connects the upper and lower sides may be oriented in an oblique direction inclined from the vertical direction.

  Further, the cross-section is U-shaped in the vertical direction, when the guide wheel of the coke oven is lifted using this suspension balance, the cross-section may be parallel to the coke chamber alignment of the coke oven. .

That is, the gist of the present invention is the following [1] to [8].

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a first embodiment of a suspension balance according to the present invention. In the suspension balance main body 21, an upper plate 22 and a lower plate 23 are connected by a side plate 24 which is a connecting member provided at one end. Both the upper plate member 22 and the lower plate member 23 have a rectangular plate shape.

  Wires 26 are respectively attached to the four corners of the upper plate member 22, and the other end of each wire 26 is bundled above the upper plate member 22, and is connected to a crane 31 (described later) that suspends the suspension balance. ing. A hydraulic cylinder 27 is provided at one end of each wire 26, i.e., at a position in contact with the upper plate member 22, and each hydraulic cylinder 27 can be expanded and contracted independently. The suspension balance main body 21 is provided with the side plate 24 only at one end portion, so that the center of gravity is shifted from the center and the posture tends to be inclined. However, the hydraulic cylinder 27 provided on the upper plate 22 is individually expanded and contracted. By adjusting, the inclination of the suspension balance main body 21 can be adjusted and the horizontal posture can be maintained.

  Wires 28 are also attached to the four corners of the lower plate member 23, respectively. A hydraulic cylinder 29 is provided at the other end of each wire 28, and the hydraulic cylinder 29 is connected to a suspended load. The length of each hydraulic cylinder 29 can be adjusted independently. By operating and contracting the hydraulic cylinder 29, the suspended load can be lifted from the ground. Further, by individually adjusting the length of the hydraulic cylinder 29, it is possible to adjust the posture of the suspended load and maintain the level.

  When adjusting the hydraulic cylinders 27 and 29, the operator operates the suspension balance in the vicinity of the suspension balance while confirming the horizontal posture of the suspension balance and the lifting state of the suspended load.

  In the first embodiment, the upper plate member 22 and the lower plate member 23 do not have to be plate-shaped, and may be a rectangular frame shape. In addition, it is preferable that the upper plate member 22 and the lower plate member 23 have the same size, but there is no practical problem even if the sizes are different as long as the horizontal position of the center of gravity is the same. In this case, the side plate 24 is inclined obliquely with respect to the vertical direction. However, from the viewpoint of strength, it is preferable that the upper plate member 22 and the lower plate member 23 have the same shape and the same size, and each of the upper plate member 22 and the lower plate member 23 has a respective one end. Most preferably, a side plate 24 that is perpendicular to the plate is attached.

FIG. 2 shows a second embodiment of the suspension balance according to the present invention.
The suspension balance main body 71 according to this embodiment is obtained by attaching a U-shaped material 73 in the vicinity of an end portion of the upper plate material 72 which is a rectangular plate material. The U-shaped material 73 is formed by connecting one end of an upper arm member 74 and a lower arm member 76 provided in parallel by a vertical column member 75 as a connecting member. The upper arm member 74 is attached to the upper plate member 72, the vertical column member 75 extends downward from the upper arm member 74, is bent at a right angle from the lower end thereof, and the lower arm member 76 extends in the horizontal direction. The lower arm member 76 of the two U-shaped members 73 serves as the lower plate member 23 in the first embodiment. That is, a wire 28 extending downward is attached to the lower side of each end portion of each lower arm member 76. A hydraulic cylinder 29 is provided at the other end of the wire 28. The hydraulic cylinder 29 can be extended or contracted independently or simultaneously to lift the suspended load. Further, one end of the wire 26 attached to the upper arm member 74 is bundled above the upper arm member 74 and connected to the crane 31. A hydraulic cylinder 27 is provided at the other end of each wire 26, and each hydraulic cylinder 27 can be extended and contracted independently, and posture control for leveling the suspension balance body 71 is performed. The location where the wire 26 is attached is not limited to the upper arm member 74, but may be the upper plate member 72.

  In the second embodiment, the upper arm member 74 may not be provided, and the upper end of the vertical column member 75 may be connected to the upper plate member 72. In this case, the upper plate member 72, the vertical column member 75, and the lower arm member 76 have a U-shaped vertical section.

FIG. 3 shows a third embodiment of the suspension balance according to the present invention.
The suspension balance body 71 ′ according to this embodiment is an application form of the second embodiment, and the difference is as follows.
The lower arm member 76 ′ extends in the direction opposite to the open end of the U-shaped portion, and is about twice as long as the lower arm member 76. Further, the upper arm member 74 has an inclined column member 80 that is inclined obliquely from the vertical direction and connects one end of the upper arm member 74 joined to the vertical column member 75 and the extended end portion of the lower arm member 76 ′. The upper arm member 74, the vertical column member 75, the lower arm member 76 ′, and the oblique column member 80 form a deformed U-shaped member 81, and this and the upper plate member 72 constitute a suspended balance body 71 ′. .

That is, as an outline of the shape of the deformed U-shaped material 81, a right-angled isosceles triangle is attached to the right side of the U-shape so that the hypotenuse faces the upper right. However, the extension member of the lower arm member 76 ′, the vertical column member 75, and the oblique column member 80 may not be isosceles triangles, and the extension part of the lower arm member 76 ′ may be longer than the vertical column member 75. Good or vice versa.
On the lower side of the lower arm member 76 ′, wires 28 extending downward are attached at three locations, both ends and substantially in the center, and a hydraulic cylinder 29 is provided at the lower end portion of each wire 28. Thereby, the wire 28 and the hydraulic cylinder 29 are provided in a total of six locations, and widened to the right front side in FIG. 3, so that it corresponds to the width of the guide wheel to be described later than in the second embodiment. The guide car can be lifted in a balanced manner. This will be described later.

FIG. 4 shows a fourth embodiment of the hanging balance according to the present invention.
The suspension balance body 71 "according to this embodiment is an application form of the second embodiment, and the difference is as follows.
The upper arm member 74 "extends in the direction opposite to the open end of the U-shaped portion and is approximately twice as long as the upper arm member 74. The upper arm member 74", the vertical column The material 75 and the lower arm material 76 form an inverted U-shaped material 82, and this and the upper plate material 72 constitute a suspension balance body 71 ".

  A downwardly extending wire 28 ′ is attached to the lower side of the upper end portion of the upper arm member 74 ″. The wire 28 ′ may have a length corresponding to the height of the suspended load. There is no need to match the length.

  On the other hand, on the upper side of the upper arm member 74 ″, the wire 26 to be connected to the crane 31 is attached to the two ends of the end portion on the opposite side to the extended side and the vicinity of the midpoint of the extended portion. The hydraulic cylinders 27 are respectively provided at the end portions of the upper arm members 74 "of the 26. The reason why the pair of attachment positions of the wires 26 is not at the end on the extended side is that the hood 67 is lighter than the guide wheel itself and the center of gravity is closer to the guide wheel. That is, if it is attached to the end portion on the extended side, it is too far from the center of gravity and the burden on the individual wires 26 increases. Therefore, the load applied to the individual wires 26 is reduced by attaching the wire 26 suspended upward not to the extended tip portion of the upper arm member 74 "but near the midpoint of the extended portion closer to the center of gravity.

  In any of the first to fourth embodiments described above, the number of the wires 26 and the wires 28 and 28 ′ is not necessarily the number as shown in FIGS. The number of wires may be increased or decreased as necessary as long as the posture control of the balance and the posture control of the entire balance can be performed.

  Although it is not necessary to provide the hydraulic cylinders 27 and 29 for all the wires 26, 28 and 28 ′ described above, if they are attached to all the wires 26, 28 and 28 ′, the horizontal posture of the suspension balance can be maintained flexibly and accurately. Therefore, it is preferable. In particular, when used in a coke oven, which will be described later, there is no sufficient space between the guide wheel 61 and the dust collecting duct 62, and it is necessary to accurately insert the lower plate member 23 or the lower arm members 76, 76 'between them, This is because it is desirable to keep the work as horizontal as possible. In addition, since different loads are applied to the respective wires, there is also a role of adjusting the stretchability of the wires.

  Further, in the first embodiment, the upper plate member 22, the lower plate member 23, and the side plate member 24, and the upper plate member 72, the upper arm members 74, 74 ″, the lower arm member 76 in the second to fourth embodiments, The material of 76 ′, the vertical column member 75, and the oblique column member 80 (hereinafter collectively referred to as “main body constituent member”) may be the same material or different materials. Good. The material is not particularly limited as long as it can withstand the load of the suspended load.

  Moreover, since the said main body structural material tends to generate | occur | produce a bending and breakage with the weight of a suspended load, it is preferable to use a material with sufficient intensity | strength. In addition to these members, a reinforcing member may be attached to a location where stress is likely to occur when the suspended load is lifted.

  Moreover, the thickness and thickness of the main body constituting material may be the same or different. Further, the thickness of the lower plate member 23 and the lower arm members 76, 76 'is determined by the gap between the obstacle (for example, the trolley wire 60 and the dust collection duct 62) and the suspended load (for example, the guide wheel 61). 23 and the lower arm members 76 and 76 'can be adjusted, and the lower plate member 23 and the lower arm members 76 and 76' may be adjusted within a gap even when the suspended load is lifted.

  Furthermore, although the magnitude | size of the said main body structural material is not specifically limited, What is necessary is just to select a suitable magnitude | size according to the magnitude | size of the obstacle in the upper part of a suspended load or a suspended load. In particular, when using the suspension balance so that the obstacle is sandwiched in the recessed portion of the U-shaped suspension balance, the size of the main body component is adjusted so that the suspension balance and the obstacle do not contact each other. It is good to do.

  The suspension balance according to the present invention is a U-shaped suspension balance having a vertical cross section, but it is not necessary that each angle forming the dent is a right angle, and each of the suspension balances may have a substantially C-shape that bends gently. . Also, the side plate 24 that connects the upper plate 22 and the lower plate 23 in the first embodiment, and the vertical arm that connects the upper arm 74, 74 "and the lower arm 76 in the second and fourth embodiments. The column member 75 may be inclined obliquely with respect to the vertical direction as long as the suspended load can be lifted, and the inclination of the oblique column member 80 in the third embodiment may be arbitrarily adjusted to some extent. However, it is desirable in terms of strength that the lower end of the oblique column member 80 is in contact with the end of the extended lower arm member 76 '. Therefore, the inclination of the oblique column member 80 is actually that of the upper and lower arm member 76'. Furthermore, the length of the vertical column 75 is not limited to one, but may be a plurality of columns provided at intervals. In this case, the end of the lower arm member 76 ' In addition to those to be joined, so that the lined one or a plurality of oblique columns between Tatehashirazai 75.

  Next, the procedure for lifting the guide wheel 61 used in the coke oven 41 by the crane 31 using the suspension balance according to the first embodiment will be described with reference to FIGS.

  First, the coke oven will be described. FIG. 5A is a conceptual diagram viewed from above the coke oven 41, and FIG. 5B is a conceptual diagram viewed from the lateral direction.

  The coke oven 41 has a structure in which a plurality of individually divided carbonization chambers 42 are arranged in parallel, and furnace lids (not shown) are provided at both ends of each carbonization chamber 42. . Above each carbonization chamber 42, coal charging ports 44 are arranged along the carbonization chamber 42, and coal is supplied from above through the coal charging ports 44. In addition, combustion chambers are provided between the respective carbonization chambers 42, and the entire adjacent carbonization chambers 42 can be heated by spreading the heat burned here.

  A rising pipe 48 for collecting the gas generated inside is provided at one end of the carbonization chamber 42. An extruder 51 is usually provided adjacent to the end on the side where the ascending pipe 48 is located. The extruder 51 can move horizontally on a rail 52 provided along the furnace lid of the extrusion port where the carbonization chambers 42 are arranged, and the ram 53 and the leveler bar 54 provided in the extruder 51 are intended. The furnace cover of the extrusion port can be opened and inserted with the horizontal position aligned with the carbonization chamber 42.

  The coke pushed out from the discharge port by the ram 53 and the leveler bar 54 is placed on a fire extinguisher 63 waiting on the lower side through a guide wheel 61 in contact with the opposite end, and a cooling tower (not shown). )) To cool. It is not realistic to attach a guide to all of the carbonization chambers 42 that carry out the carry-out, and the guide wheel 61 and the fire extinguisher 63 are moved to the end of the carbonization chamber 42 when carrying out the carry-out. A guide car rail 64 and a fire extinguisher rail 65 are provided for moving the guide car 61 and the fire extinguisher 63 along the furnace cover, respectively. The guide car rail 64 is provided at a height 0.5 to 1 m lower than the floor surface of the carbonization chamber 42 and adjacent to the furnace cover of the discharge port. On the other hand, since the fire extinguisher rail 65 is for receiving the coke dropped downward after moving horizontally in the guide car 61 by the fire extinguishing car 63, the rail for the guide car is used in parallel with the rail for the guide car 64. It is provided below the rail 64. Also, a dust collection duct 62 for collecting dust generated from the guide wheel 61 is usually provided above the furnace lid at the discharge port, and is guided from the end so that dust can be collected at the upper part of the guide wheel 61. The upper part of the car 61 is covered. Further, a trolley wire 60 for supplying power is provided in parallel with the dust collection duct 62.

  FIG. 6 shows a perspective view of the guide wheel 61. The central portion is covered with a hood 67 for preventing dust and hot air generated when coke is received and dropped downward. Although not shown, there is a lattice for guiding coke inside the hood 67, and a saddle 68, which is a beam-like material that supports the entire guide wheel 61, extends in the direction of the guide vehicle rail 64 below the lattice. ing. Both end portions of the saddle 68 protruding from the bottom of the hood 67 are once bent upward and then horizontally extended at a position slightly higher than the central portion. Below these both end portions, there are provided wheels 70 for enabling the guide wheel 61 to move along the guide wheel rails 64. When viewed from the horizontal direction, a hood 67 covers the center portion of the saddle 68, and both ends of the saddle 68 extend on both sides of the bottom of the hood 67 so that the wheel 70 attached therebelow can be seen. Further, at both ends of the guide wheel 61 in the rail direction, a driver's cab 77 for operating and controlling the guide wheel 61 is provided, and the wheel 70 is located directly below the driver's cab 77. In the figure, the cab 77 has three levels, but the number of levels is not particularly limited. A cab floor material 78 to which the wire 28 with the hydraulic cylinder 29 can be attached at the end is provided at the bottom of the cab 77. Further, a dust collecting connector 66 for connecting to the dust collecting duct 62 is provided so as to protrude from the upper center portion.

  FIG. 7 shows the relationship between the coke oven 41, the crane 31, and the suspension balance according to the working embodiment. 7 shows the suspension balance body 71 according to the second embodiment, the suspension balance body 21 according to the first embodiment, the suspension balance body 71 ′ according to the third embodiment, The suspension balance body 71 '' according to the fourth embodiment may be used. However, in the case of the suspension balance body 21, the dust collecting connector 66 is removed. FIGS. 8A and 8B are the first embodiment. Fig. 9 shows an enlarged view of the suspension balance according to Fig. 9. Fig. 9 shows a second embodiment, Fig. 10 shows a third embodiment, and Fig. 11 shows a guide using the suspension balance according to the fourth embodiment. It is a perspective view of the guide vehicle periphery at the time of lifting a car.

  In FIGS. 10 and 11, the guide vehicle rail 64 ′ below the tip portion of the hood 67 is an auxiliary rail called a third rail, and is provided mainly to support the weight of the hood 67. . This is not directly related to the shape of the suspension balances 71 ′ and 71 ″, and is not always necessary. However, when a large weight is applied to the hood 67 side, the stability can be improved by laying it. That is, the guide wheel 61 using the suspension balance according to the first and second embodiments may have a saddle 68 'and a wheel 70' for the guide wheel rail 64 '.

  A suspension balance (21, 71, 71 ′ or 71 ″. Hereinafter, abbreviated as “21 or 71”) according to the present invention is a trolley wire 60 provided at an end portion on the side of discharging the coke. The guide wheel 61 is lifted from above by the crane 31 while avoiding contact with the dust collection duct 62. Since the trolley wire 60 supplies power and the dust collection duct 62 is provided above the guide wheel 61 for collecting dust generated in the coke oven 41, these are placed on the suspension balance body (21 or 71). The wire of the crane 31 is suspended without contacting the trolley wire 60 or the dust collection duct 62 by being accommodated between the concave portions of the members (22, 72, 74) and the lower members (23, 76). The guide wheel 61 can be lifted. In the case of the first embodiment, it is necessary to remove the dust collecting connector 66 because it interferes with the lower plate 23, but the suspension balance body 71 according to the second to fourth embodiments has a plate or frame material on the lower side. Instead, the lower arm member 76 is attached to both ends, and the central portion is opened downward, so that the dust collecting connector 66 is accommodated between the lower arm members 76. There is no need to remove it. However, for that purpose, in the second to fourth embodiments, it is preferable that the distance between the two lower arm members 76 is at least longer than the length of the dust collecting connector in the rail direction above the guide wheel 61.

  The upper member (upper plate member 22, upper plate member 72, or upper arm member 74, 74 ") according to the present invention is connected to the hook 32 of the crane 31 with a wire, and the suspension balance body (21 or 71) is moved. At that time, the lower member (the lower plate member 23 or the lower arm members 76, 76 ′) of the lifting balance is inserted into the vertical gap between the dust collection duct 62 and the guide wheel 61. Further, the upper member is provided. The horizontal posture of the suspension balance body is maintained by extending and contracting the hydraulic cylinder 27. After the lower member enters the vertical gap between the dust collection duct 62 and the guide wheel 61, the hydraulic cylinder is attached to the lower member. As many wires 28 having 29 are connected as necessary, and the hydraulic cylinders are attached to the cab floor material 78 of the guide wheel 61. Fig. 8 shows an example in which the hydraulic cylinders 29 are attached to the cab floor material 78. As shown in FIGS. 8A and 8B, the attachment position may be the end of the cab floor material 78 on the direction side perpendicular to the rail direction, or may be the end in the direction parallel to the rail. A plate member 69 having a strength capable of supporting the guide wheel 61 may be inserted between the central portion of the saddle 68 and the guide vehicle rail 64, and the plate member 69 and the hydraulic cylinder 29 may be connected. This is an example in which a hydraulic cylinder 29 is attached to a plate material 69. Among these, in Fig. 10 and Fig. 11 according to the third and fourth embodiments, the wire 28 (28 from almost right above the plate material 69 protruding forward in the figure. Since ') is lowered, the guide wheel can be lifted in a more balanced manner than in the second embodiment in which the wire is stretched only diagonally, and the load applied to the hydraulic cylinder 29 is small. It becomes as.

  10 and 11 according to the third and fourth embodiments, the two hydraulic cylinders 29 are connected to the plate material 69 and the hydraulic cylinder 29 connected to the intermediate wire 28 and the furnace-side wire 28 is operated. By connecting to the room floor material 78, each wire 28 has an inclination close to the vertical direction, so that the load on the wire 28 and the hydraulic cylinder 29 can be reduced.

  By the way, the upper end of the wire 28 provided in the lower member may be directly fixed to the lower member of the suspension balance body (21 or 71), but a pulley 30 is provided instead of a fixture at the lower portion of the suspension balance body. The lower member may be provided on the pulley 30 so that the wire 28 is provided. In this case, the upper end of the wire 28 is fixed to a wire fixture 79 provided on the upper portion of the guide wheel 61 through the pulley 30. At this time, the wire 28 connected to the hydraulic cylinder 29 on the furnace side is fixed to a wire fixture 79 provided on the opposite side of the furnace, and the wire 28 connected to the hydraulic cylinder 29 on the opposite side of the furnace is provided on the furnace side. Fixing to the fixture 79 is preferable because the cylinder stroke and wire elongation can be adjusted. In this case, the wires 28 cross over the guide wheel 61. FIG. 8A shows an example in which the wires 28 are crossed in this way.

  After confirming that the cab floor material 78 or the plate material 69 and the hydraulic cylinder 29 are connected, the upper end of the wire 28 is fixed to the suspension balance body (21 or 71) or the wire fixture 79 above the guide wheel 61. After confirming this, the hydraulic cylinder 29 is operated and contracted, the wheel of the guide wheel 61 is removed from the guide wheel rail 64, and the guide wheel 61 is lifted from the guide wheel rail 64. In that state, the crane 31 is moved horizontally from the bottom of the dust collection duct 62 by the crane 31, and is taken to a storage place or a repair place and lowered.

  During the above procedure, between the upper member and the lower member of the above-described suspension balance body, the dust collection duct 62 that has conventionally been an obstacle and the protruding portion of the trolley wire 60 extending in parallel therewith are accommodated. Therefore, the suspension balance body can be disposed directly above the guide wheel 61 under the dust collection duct 62 and the trolley wire 60. At this time, not only the suspension balance main body but also the wires 26 and 28 attached thereto do not need to contact the dust collection duct 62 and the trolley wire 60. The guide wheel 61 can be lifted without moving the lifting balance itself by moving only the hydraulic cylinder 29 provided below the lower member, rather than moving the crane up and down. Once lifted from the guide car rail 64, it can be moved horizontally by the crane, and once the guide car 61 is removed from below the trolley wire 60 or the dust collecting duct 62, it is moved upward by lifting the crane. Is also possible freely.

  In the case of repairing the guide wheel 61, the crane 31 is used to move to a repair place with a good work environment, and the guide wheel 61 is once separated from the wire 28 for repair work. After the repair work is completed, the wire 28 is attached to the guide wheel 61 again. On the other hand, when this guide wheel 61 is replaced with a new guide wheel 61, the old guide wheel 61 is once lowered to a storage location, and the wire 28 attached to the lower member is removed from the guide wheel 61. Then, the removed wire 28 is attached to a new guide wheel 61 prepared in advance.

  In any case, after the wire 28 is attached to the guide wheel 61, the hydraulic cylinder 29 is operated to lift the guide wheel 61, and the crane 31 is moved to move to the side of the coke oven 41. At this time, the guide wheel 61 suspended so that the protruding portion of the dust collection duct 62 is accommodated between the upper member and the lower member of the suspension balance body (21 or 71) in the same manner as described above. It arrange | positions under the trolley wire 60 and the dust collection duct 62, and it lowers | hangs on the rail 64 for guide vehicles, and complete | finishes replacement | exchange and repair work.
