Description

[Detailed description of the invention] (Field of industrial application) This invention is applicable to carts and assemblies (furnace body tilting device, furnace body support device, electrical components, etc.) which are ancillary equipment for pig iron mixing cars.
This invention relates to a device for quickly replacing a furnace body and a furnace body at a refractory repair shop or the like.

(Prior art) Conventionally, for example, when inspecting or repairing the furnace body of a pig iron mixer car or replacing refractories, the pig iron mixer car was transported to a designated repair shop and the cart and assembly were still attached to the furnace body. , inspecting, repairing, or replacing refractories inside the furnace body. However, during this period, not only the cart but also the assembly must be left unattended, which is extremely uneconomical.

In other words, the manufacturing cost of one pig iron mixing car is usually the furnace body.
It is said that 50% of the production cost is 50% of the production cost of the trolley and assembly, and it is possible to reduce the total production cost by half just by omitting the trolley and assembly, so it is important to increase the utilization rate of the trolley and assembly as much as possible. It is. Therefore, it is required to set and utilize other furnace bodies on the idle carriage and assembly, so that a single carriage and assembly can handle many furnace bodies. However, there is no device for quickly replacing the cart and assembly with the furnace body, and the development of such a device has been desired.

(Objective of the invention) In order to satisfy the above-mentioned requirements, an object of the present invention is to obtain a furnace body exchange device that can quickly exchange a furnace body.

(Structure of the invention) The present invention provides a bogie that is movable in a direction intersecting the running rail of a pig iron mixer car, a running rail that can communicate with the running rail on the moving bogie, and a furnace that can be raised and lowered. This is a furnace body exchange device for a pig iron mixer car, characterized in that a body support device is provided.

(Example) The following will explain the embodiments shown in the drawings.

1 and 2, a pit 6 is provided in the middle of the pig iron mixer rails 3, 3' at a repair shop for refractories, etc. of pig iron mixer cars, and the rails 3, 3' are placed in the pit 6.
A movable trolley 1 and running rails 4 for the trolley 1 are provided so as to be able to run perpendicular to the trolley. Movement of the movable trolley 1 is performed by expanding and contracting a moving device 7 provided in the pit. In this embodiment, the moving device 7 is described as an example of a cylinder, but various known methods necessary for moving a moving cart can be applied.

The moving device 7 is swingably engaged with a bracket 10 attached to a pit with a pin 9, and the telescopic rod of the moving device is engaged with the moving cart 1 with a pin 8. Thus, the moving trolley 1 becomes the moving device 7
As the rod expands and contracts, it can move (forward and backward) on the running rail 4. The movable trolley 1 is equipped with an appropriate number of wheels 5, and travels on the rails 4 via the wheels.

Also, on the movable trolley 1, there are ground side rails 3, 3'.
Correspondingly, two or more sets of rails 2, 2' (in this example, 2
The case of a pair is shown. ) are arranged in parallel,
In the set stop position of the movable truck 1, the rails 2 or 2' are connected correspondingly to the rails 3, 3' to facilitate the passage of the pig iron mixer.

Moreover, the movable cart 1 is a portable cart for holding the furnace body 11 that has been pushed up. The structure is such that the assembly type support stands 18, 18' and the support stand runners 19 can be arranged so that the furnace body can be supported at a minimum of two places.

Next, the operation of this embodiment will be explained. In FIG. 5A, first, the movable cart 1 is waiting at a position closer to the repair shop B, and in this state, the rails 3, 3' and the rail 2 are in communication. Therefore, using the rails 2 on the mobile truck 1 on the repair shop A side, the pig iron mixer car is passed through and stopped at a fixed position.

Thereafter, as shown in FIG.
4 and the trunnion 15, which is provided integrally with the furnace body, are separated and separated from the assembly of the truck 12, bearing stand 13, and trunnion bearing 14, as shown in FIG.
At this time, since the furnace body 11 is moved laterally on the movable trolley 1 as described later, in order to eliminate the risk of interference, the
The second assembly is moved slightly in the directions of arrows H and H' in FIG.

When the assembly including the truck 12 of the pig iron mixer car has completed its movement, two sets of support stands 18 and 1 are placed below the furnace body 11.
8', the liner 19 is inserted to stably support the furnace body 11. It is desirable to attach the liner 19 to the moving cart in advance [Fig. 4A].

Once the mounting of the support stands 18, 18' and the support of the furnace body have been completed, the jack 17 can be removed as necessary and used for pushing up the furnace body 11 of the next pig iron mixing car.

Furthermore, if the jack 17 is to be stably fixed on the movable carriage 1, the support stands 18, 18' are not necessarily required.

Next, as shown in FIG. 5B, the furnace body 11a supported on the movable trolley 1 in FIG. 5A is moved by the movable trolley 1 to be placed in the repair shop A. At the time when the furnace body 11a has completed moving to the repair shop A, the other pair of bogie upper rails (2' in FIG. 1) provided on the movable bogie 1 are connected to the ground side rails 3, 3'. It is now in a state where it is possible for another pig-mixing vehicle to enter.

In FIG. 5C, when the repair of the furnace body 11a is completed, another pig iron mixer car stops advancing, separates the furnace body 11b in the same procedure as in A above, and supports the furnace body 11b on the moving cart 1. .

Next, in FIG. 5D, the movable cart 1 is moved to the repair shop B side and the furnace body 11b is placed in the repair position. When the arrangement is completed, the repaired furnace body 11a is located at a position where it can be assembled into an assembly such as the cart 12 separated from the furnace body 11b. Thereafter, by performing the procedure described in FIG. 5A in reverse, the furnace body 11
a can be incorporated into the assembly, thus completing the furnace replacement work.

(Effects of the invention) According to the invention, since it is possible to quickly replace the cart and assembly with the furnace body, the operating rate of the cart and assembly is improved, and even with a small number of carts and assemblies, many furnaces can be replaced. It has extremely excellent economical effects, such as being able to use the machine and reducing the production cost per pig iron mixing car.
