Description

[Detailed Description of the Invention] Technical Field The present invention relates to a demolition device for cutting and excavating a refractory lined in a container containing molten metal, such as a tundish.

PRIOR ART In general, containers lined with refractories that hold molten metal will need to be repaired as the refractories melt and wear away or slags stick to them as they are used. Workers entered these containers and used pick breakers, hammer drills, etc. However, the efficiency of the above-mentioned work is low, and the work cannot be started until the container has cooled down, so recently, equipment equipped with breakers and cutters has been used.

Problems with the Prior Art Incidentally, in the above device, the breaker and cutter do not operate independently and in detail, and the operator cannot sufficiently observe their operating status, so it is easy to completely disassemble the device. However, it was difficult to operate when repairing the thin parts.

Purpose and structure of the present invention In view of the above-mentioned circumstances, the present invention has been developed to dismantle lining refractories, which allows not only full-scale dismantling, but also fine chipping and cutting, by freely operating breakers or cutters while observing the driver. The purpose of this device is to provide a device, and its gist is that a traveling trolley is placed on rails arranged in the front-rear direction so as to be able to run freely, and a horizontal frame that runs along the left-right direction is attached to the traveling trolley. , the base of a breaker boom that can freely rotate in the vertical direction is attached, a cutter support part is attached to this horizontal frame so as to be movable in the left and right direction, and the cutter is attached to this cutter support part via a telescopic cutter support. The base of the breaker boom is attached so as to be swingable, a cutter that is rotatably driven is provided at the tip of the cutter attachment section, and the base of a breaker arm is rotatably attached to the tip of the breaker boom. A turning mechanism is provided in the intermediate portion to rotate the tip of the breaker arm around the longitudinal axis of the breaker arm, and the base end of the breaker mounting portion is attached to the tip of the breaker arm so that it can swing freely. A breaker is attached to the breaker attachment part so as to be movable in the length direction, and an operator house for driving and operating the movable part is attached to a predetermined position of the running cart where the cutter and the tip of the breaker can be seen. It is characterized by being

Function The demolition device of the present invention moves the traveling cart and the cutter support, expands and contracts the cutter support, and
By appropriately swinging the head of the cutter attachment part,
While freely adjusting the position of the cutter, the cutter is applied to the refractory material, and the cutter is driven to rotate to cut the refractory material.
In addition, by appropriately rotating the breaker boom and breaker arm, rotating using the rotating mechanism, swinging the breaker mounting part, and moving the breaker,
While freely adjusting the position of the breaker, the tip of the breaker is brought into contact with the refractory material, and the tip is driven to perform chiseling. In this case, these operations can be carried out by an operator from the operator's house while visually observing the cutters and breakers.

Specific operations and effects of the present invention When dismantling refractories using the lined refractory dismantling device (hereinafter referred to as the device) configured as described above, for example, a tundish 30 is used as shown in FIG. Position it between stages 1 and 1. After that, when cutting the refractory 31, the traveling trolley 4
traveling on the rail 2, movement of the cutter support section 7 in the left and right direction on the horizontal frame 6, hydraulic cylinders 12,1
After the position of the cutter 18 is freely adjusted by swinging back and forth and left and right by the expansion and contraction of the cutter 7 and by the expansion and contraction of the cutter support 11, the cutter 18 is rotationally driven to cut the part that needs to be removed. In addition, when removing refractories deeply, the traveling trolley 4 runs on the rail 2, and the hydraulic cylinders 20a, 22, 23a
The tip position of the breaker 24 can be freely adjusted by the rotation due to expansion and contraction and the rotation of the rotation mechanism 21a.
The breaker is applied to a predetermined portion of the refractory and the breaker is driven by the hydraulic cylinder 25 to perform chipping. In this case, since the position of the breaker 24 can be freely selected in the direction of its tip as shown by the breaker 24' indicated by a two-dot chain line, small portions can be bent or removed.

As mentioned above, the cutter 18 and the breaker 24 are
It can be adjusted so that a desired part of the lower refractory surface can be cut and excavated, and the above operations are performed by an operator in the operator house 26.
From the operator house 26, the above cutter 18,
No matter how the breaker 24 is adjusted, the operation of its tip can be clearly observed, so not only can the entire refractory 31 be dismantled, but only small parts can be cut or excavated by the operator. This can be done by.
