Description

  The present invention relates to a furnace wall brick in a coke oven carbonization chamber for repairing the furnace wall by sending it together with an operator to the furnace wall repair of the coke oven carbonization chamber, in particular, transshipment or partial repair of the furnace wall brick. It relates to transshipment and repair equipment.

  Conventionally, furnace wall repair in the coke oven carbonization chamber has been carried out by stopping the operation of the coke oven or by spraying the repair portion by inserting a castable injection pipe from the coal inlet at the top of the carbonization chamber. However, stopping the operation of the coke oven not only has a large loss of heat, but also the preparation work and the work up to resumption of operation are complicated. On the other hand, although spraying a castable can cope with a simple repair, A large wall defect cannot be completely repaired.

On the other hand, Patent Document 1 discloses a heat insulation box structure for hot repair work as a furnace wall repair device for a coke oven carbonization chamber. This technique is a device that repairs in a hot state by inserting the heat insulation box into the carbonization chamber, and an operator enters the heat insulation box to perform repair. However, in this technology, a heat insulation box is formed by a cooling water pipe with a bottom surface and a ceiling surface that are narrower than the furnace wall spacing on both sides of the carbonization chamber, and a heat insulation board is detachably attached to the outside of the box. It is structured.

  However, the furnace wall width of the coking oven carbonization chamber is very narrow, about 400 mm or less, and this furnace wall repair device is used to sufficiently insulate the worker when an operator enters the insulation box. Even if the outer wall (insulation board) of the steel is made as large as the furnace width of the carbonization chamber, it is still narrow.

  In addition, the furnace wall of the coke oven carbonization chamber is uneven due to the operation of the coke oven, and is not flat. There are also various deposits on the wall of the carbonization chamber. For this reason, if the furnace wall repairing device has a width that is almost the width of the furnace wall, the furnace wall repairing device is caught on the furnace wall, and the furnace wall repairing device cannot be smoothly inserted into the carbonization chamber.

  Therefore, the present invention proposes a novel structure of a furnace wall brick transshipment / repair device that can be smoothly charged into the carbonization chamber and that can sufficiently secure the work space of the worker entering the interior. For the purpose.

  As a result of earnest examination for the realization of the above object, the inventors are not a box structure surrounded by a heat insulating plate as a device that exerts its power at the time of transshipment of furnace wall bricks or partial repair of brick walls, It has been found that the above-mentioned drawbacks of the conventional apparatus can be overcome by making the other parts except the charging front face open, and the present invention has been completed.

A strip-shaped floor plate disposed along the longitudinal direction of the scaffold main frame, and a ladder-shaped rear frame attached to the front end of the ladder-like rear frame. This is a furnace wall brick transshipment / repair device in a coke oven carbonization chamber characterized by being rotatably supported in a plurality of stages in the height direction.

In addition, the apparatus according to the present invention can provide a solution that is preferably configured as follows.
(1) The scaffold main frame is a loop formed by bending a pipe into a square according to the shape and size of the carbonization chamber,
(2) The lower end of the scaffold main frame includes one or more sliders;
(3) The heat sink shields the heat in the carbonization chamber at the front end of the scaffold main frame, parallel to the frame in the loading / withdrawing mode, and orthogonal to the frame in the working mode. Installed so that it can be turned in a direction,
(4) The rear frame is provided with the floor plate fixing plate at the position of the floor plate arrangement level in the height direction,
(5) The floor plate fixing plate has a pair of pin holes for pivotally supporting the floor plate and fixing the rotation stop position of the floor plate via a bolt,
(6) The floorboard is disposed so as to be suspended between the front end portion and the rear frame of the scaffold main frame,
(7) The floorboard rotates so as to maintain an upright posture in the loading / withdrawing mode, and rotates to form a scaffold while maintaining a horizontal posture in the working mode;
(8) The floor board is cocoon-shaped,
(9) The furnace wall brick transshipment / repair device is to be sent into the carbonization chamber through a guide device movably disposed in front of the carbonization chamber or pulled out from the carbonization chamber,

  The furnace wall brick transshipment / repair device in the coke oven carbonization chamber of the present invention is configured as described above, so that it is possible to eliminate the trouble of being caught on the furnace wall during charging into the carbonization chamber, Even so, it is possible to secure a sufficient working space for the worker entering the inside. As a result, the work efficiency of furnace wall repair can be significantly improved.

  In addition, according to the present invention, the main part of the apparatus is not a box structure but an open type, so that the structure is simple, lightweight, and advantageous in terms of manufacturing cost. It is effective for partial repair of furnace wall bricks near the entry side of the carbonization chamber.

  In addition, according to the present invention, since the release structure does not have a side wall as in the prior art, a wide range of the furnace wall can be transshipped and repaired at once, and in addition to the floor plate shape (insulator shape) The removal of the brick waste is easy.

  Further, according to the present invention, the floor plate and the heat insulating plate are made movable so as not to obstruct the loading and unloading of the apparatus, and the slider is provided at the lower part of the scaffold main frame. The loading and unloading work becomes easier.

  1 to 4 show an example of a preferred embodiment of the present invention, and the feature thereof is that the basic configuration is an open type centering on a scaffold main frame. It is a transshipment work that is mainly done with the furnace wall bricks cooled to some extent, or when repairing the vicinity of the entrance side of the carbonization chamber where heat dissipation is significant, only the role of the so-called front heat shield plate The present invention provides an effective device when performing partial repairs in a range where work is sufficiently possible, or when repairing a wide area.

  In the illustrated example, reference numeral 1 denotes a loop-shaped scaffold main frame in which a square or round steel pipe is used as a preferred example, and this is bent into a substantially square shape according to the shape of the carbonization chamber R and its size. This frame is a part forming the skeleton of the device according to the present invention.

  A strip-shaped heat insulating plate 2 having a width slightly smaller than the horizontal width of the carbonization chamber R can be turned at the front end portion of the scaffold frame 1 which is in front of the charging side, that is, heat shielding is performed during charging and during work. When necessary, the direction is perpendicular to the traveling direction (the charging direction) as shown in FIGS. 1 and 2, while when no heat shielding is required, the direction is parallel to the traveling direction as shown in FIG. 4B. It is installed so that it becomes the direction.

  On the other hand, a ladder-like rear frame 3 having a width substantially equal to the lateral width of the carbonization chamber R but slightly larger is fixed to the rear end portion of the scaffold frame 1. The rear frame 3 is provided with a floor plate fixing plate 3a for pivotally supporting the floor plate 4 and fixing its orientation (posture) at a position where the floor plate 4 to be described later is disposed. ing. Accordingly, the floor plate fixing plates 3a are provided by the number of floor plates 4 arranged in a plurality of stages (two stages in the illustrated example) in the height direction of the scaffold frame 1.

  Next, the floor plate 4 extends along the longitudinal direction of the scaffold main frame 1, spans between the front end portion thereof and the floor plate fixing plate 3a of the rear frame, and extends in a plurality of stages in the height direction. It is preferable that a strip-like work scaffold is provided, and a lever plate or the like as shown in the drawing is used. The floor plate 4 is pivotally supported with respect to the scaffold frame 1 so as to be rotatable in a vertical plane. When the floor plate 4 is inserted into or pulled out from the carbonization chamber R of the apparatus, an upright posture is provided. While in the working mode, it rotates to maintain a horizontal posture in order to provide a scaffold for the worker, and in each posture, particularly in the latter case, as shown in FIG. The posture can be fixed to the floor plate solid plate 3a using bolts 5 and 5 'via bolts.

  In addition, it is preferable to attach one or more various sliders 6 and 7 to the lower part of the scaffold frame 1 as needed. Due to the presence of these sliders 6 and 7, the scaffold main frame 1 can smoothly insert into and pull out from the carbonizing chamber R. Therefore, if the sliders 6 and 7 are mounted so as to be slightly smaller than the width of the carbonization chamber and slightly higher than the bottom wall of the carbonization chamber, the above-described charging and drawing operations can be performed smoothly. It becomes like this.

  Next, a description will be given of a method (operation) in which such a scaffold frame, that is, a furnace wall brick transshipment / repair device according to the present invention is inserted into or pulled out from the carbonization chamber. As shown in FIGS. 2 to 4, such an operation uses a guide device G that is movably disposed in front of the coke oven carbonization chamber R via a traveling crane or the like. The guide device G is preferably composed of a pair of tower-shaped guide frames Gt standing on both sides of the carbonization chamber inlet, and the transshipment / repair device F is sandwiched between the tower-shaped guide frames Gt. In addition, as shown in the drawing, a structure of a triple type in which the transshipment / repair device F can be loaded and withdrawn into and from the two carbonization chambers R may be employed.

  The guide device G is inserted into the carbonization chamber R from the state where the transshipment / repair device F is placed on the bottom frame 8 of the tower-shaped guide frame Gt. As shown in FIG. 3, it is suspended by a crane C, and as shown in FIG. 4 (b), it is fed in a state of being inclined forward toward the room at the time of charging, and horizontally after charging.
