Description

[Detailed Description of the Invention] The present invention relates to a stirring slag remover used for a melting furnace such as an aluminum melting furnace.

In a melting furnace such as an aluminum melting furnace, stirring work for stirring the molten metal or work for removing slag inside the furnace is required. In this case, the work could not be carried out efficiently with a device in which only working tools for stirring, sludge removal, etc. were attached to the tip of the arm. In other words, since the hearth of a melting furnace is shaped like a bowl, and the inner wall of the furnace is circular or square, it is necessary to operate the working tools along these surfaces, but conventionally, such operations were not possible. As a result, work efficiency had to decline.

The present invention was provided with the aim of solving the problems of the conventional technology, and its features include a trolley 1 that can run forward and backward, left and right, and turn; Link mechanism 4
A support frame 3 supported so as to be able to rise and fall and tilt freely via
, a telescoping arm 18 provided on the support frame 3 so as to be extendable in the front-rear direction and rotatable around an axis in the front-rear direction, a work tool 36 attached to the tip of the telescoping arm 18 , and a telescoping arm 18 . and a rotation mechanism 23 that rotates the telescopic arm 18 around its axis. It has a movable arm 5, an elevating cylinder 7 that moves the swinging arm 5 up and down, and a rear tilting cylinder 6 whose both ends are pivotally connected to the truck 1 and the support frame 3.

The invention will now be described in detail with reference to the illustrated embodiments.

In FIGS. 1 and 2, reference numeral 1 denotes a truck, which has four wheels 2, and by steering the wheels 2, it moves forward and backward.
Left and right and turning are possible at will. Reference numeral 3 denotes a support frame disposed on the truck 1 in the front-rear direction, and is made of a pair of left and right channel members, etc., and the support frame 3 is supported on the truck 1 via a link mechanism 4 so as to be movable up and down and tiltable. The link mechanism 4 includes a pair of swing arms 5 on the front side whose both ends are pivotally connected to the truck 1 and the support frame 3, and a pair on the rear side whose both ends are pivotally connected to the truck 1 and the support frame 3. The swing arm 5 is vertically swingable by the expansion and contraction of the elevating cylinder 7. Therefore, the support frame 3 can be moved up and down by the expansion and contraction of the lifting cylinder 7, and can be tilted forward and down and backward by the expansion and contraction of the tilting cylinder 6 so that the rear end side can move up and down. Reference numeral 8 denotes a movable frame, which is made of a pair of channel materials, etc., and this movable frame 8 is supported by the support frame 3 through guide rollers (not shown) so as to be movable in the front and back direction.
is driven in and out by a drive device 9. Drive device 9
As shown in FIGS. 3 and 4, a motor 12 is attached to a mounting base 10 at the rear end of the movable frame 8 via a bracket 11, and a motor 12 is supported by the movable frame 8 via a bearing 13 and is a winding motor. A rotating shaft 15 interlockingly connected to the motor 12 via a hook transmission mechanism 14, a pinion 16 fixed to both ends of the rotating shaft 15, and a rack 17 mounted on the support frame 3 with which the pinion 16 engages. It consists of Reference numeral 18 denotes a telescopic arm made of a cylindrical body, which connects the connecting member 1 of the movable frame 8 as shown in FIG.
It is supported so as to be able to expand and contract (come and go) in the front and back direction via a pair of left and right receiving rollers 20 pivotally mounted to the rollers 9, and also to be rotatably supported around its axis by receiving rolls 21 as shown in FIG. There is. The telescoping arm 18 is telescopically and rotationally driven by a telescoping mechanism 22 and a rotating mechanism 23. As shown in FIG. 5, the telescoping mechanism 22 has a drum-shaped feed roller 24 that comes into contact with the upper surface of the telescoping arm 18, and a motor 26 that drives this via a winding transmission mechanism 25. The motor 26 is attached to a gate-shaped lifting frame 27, and the lifting frame 27 is connected to the pressing cylinder 2.
8 to the fixed frame 29 on the movable frame 8 side. As shown in FIG.
and a motor 32 that drives this via a winding transmission mechanism 31. These rotating rollers 30 and motor 32 are attached to a gate-shaped lifting frame 33, and the lifting frame 33 is connected to It is attached to the fixed frame 35 on the movable frame 8 side. A stirring tool 36 is detachably attached to the tip of the telescopic arm 18. Note that instead of this working tool 36, it is also possible to install a furnace cleaning working tool 37 as shown in FIGS. 7 and 8.

Next, the work will be explained. When cleaning the inside of the aluminum melting furnace 38, the movable frame 8 is moved forward as shown in FIGS. 9 and 10, and the telescoping arm 18 is extended forward and inserted into the melting furnace 38 through the opening 40. After that, work tool 36 or 3
7 is moved along the inner periphery of the hearth 41 and the furnace wall 42. For example, when moving the work tool 36 along the hearth 41, the support frame 3 is raised by the lifting cylinder 7 from the solid line state in FIG. While tilting, the movable frame 8 and the telescopic arm 18 may be moved in the direction of contraction. In this case, the cart 1 is moved back and forth as necessary. For the left and right slopes of the hearth 41, the telescopic arms 18
The lower end of the working tool 36 may be brought into contact with the hearth 41 by slightly rotating it around the axis, and the cart 1 may be gradually rotated. The turning at this time is performed around point A of the opening 40. When moving the working tool 36 along the inner periphery of the furnace wall 42, the rotary arm 18 may be rotated to move along the furnace wall 42.

During such work, the front and rear, left and right, and turning movements of the trolley 1, the lifting and lowering and tilting movements of the support frame 3, and the extending and contracting movements of the movable frame 8 and the telescopic arm 18,
By performing the rotation operation of the telescopic arm 18 in any combination, the working tool 36 can be placed in any desired posture, and the cleaning work inside the furnace can be performed easily and efficiently.

During the slag removal work, a working tool 36 as shown in FIGS. 1 and 2 is attached to the tip of the telescoping arm 18. Also, remove the sludge from the apron 43 to the bag 4.
Note that if the telescopic arm 18 has a small telescopic stroke, the movable frame 8 may be omitted.

When stirring the molten metal 39, the working tool 36 is dipped into the molten metal 39.

According to the present invention, the work tool can be moved in any posture by appropriately combining the front/back, left/right, and turning movements of the cart, the lifting/lowering and tilting movements of the support frame, and the extending/contracting/rotating movements of the telescoping arm. This makes it possible to easily and efficiently perform agitation inside the furnace, removal of sludge, and cleaning inside the furnace. Further, since the trolley can move not only back and forth, but also move left and right and turn, the lateral position of the work tool can be easily changed. Furthermore, the link mechanism includes a swinging arm on the front side whose both ends are pivotally connected to the trolley and the support frame, an elevating cylinder 7 that moves this swinging arm up and down, and a lift cylinder 7 whose both ends are pivotally connected to the trolley and the support frame. Since it has a connected tilting cylinder on the rear side, the support frame can be moved up and down and tilted with a simple structure.
It has the advantage of making the whole thing more compact.
