    The operator of a taphole drilling apparatus for blast furnaces performs manual changes on the apparatus in its safe position of rest and operation by remote control and automatic latching in hazardous taphole work including drilling and subsequent driving, release, and extraction of a tap bar. The usual guide rail (22) carrying reciprocably a hammer drill (30) thereon incorporates a remotely openable automatically latching centralizer (42) at its forward end and an extraction carriage (29) on which, after removal of the drill steel (43), an impact sleeve (50) can be manually mounted for being impacted by the hammer drill (30). In one mounting position (Fig 5) of the impact sleeve (50), a latch (57) therein is biased to automatically latch the shank of a tap bar (53) thereto for extraction by impacts. In a 180° counter-turned position the latch (57) will fall aside and the mounted sleeve (50) is used to drive the tap bar while guided by the centralizer (42). The sleeve (50) can then be retracted freely from the tap bar (53) and the guide rail (22) freed by unlatching the centralizer (42) from the tap bar (53).

    0 fig. 1 and 2 are shown in the working position near the wall of the blast furnace 1 in the freshly applied embedding of the taphole 2, in which the initial discharge opening must first be drilled and then
    A closure or sacrificial rod 3 is inserted completely through the embedment material as an extension of the initial opening. The carriage 5 can move forward and back along the direction of the mainwrame k under the action of the feed motor 6 and the feed chain 7 mounted on sprockets 8.
    As can be seen from FIG. 3 and, the carriage 5 5 is movably suspended on opposite flanges 9 located on the guide rail 10 by means of pairs of opposing rollers 11. As shown in FIG. and 5, it is advisable that the carriage 5 be divided into the front part, the carriage 12 of the extraction device, and the rear part, the carriage 5 of the perforator, the latter being carried by a conventional pneumatic translator 13 having the usual built-in rotation means I of the perforator.
    Chain 7 through shackle 15 and the driving pin 16 installed in it (Fig. 5) is in a drive connection with a carriage 12 of the extraction device, which, in turn, is connected to the perforator carriage 5 by means of side bolts 17 (Fig. 3 fixed on the protrusion 18, made nominal on the carriage 5, and passing through the spring 19 on the carriage 12 of the extraction device, located between the vibration damping nodes of the disc springs 20, which are under appropriate compressive force. The guide k is mounted on the stand 21 and the transverse console 22 with the possibility the rotation, as shown by the arrow in Fig. 2, around the vertical axis 23 between the non-working position set aside (not shown by the working position shown in Fig. 1 and 2, and vice versa, and the haklon using the console 22 around the horizontal axis 2 between the horizontal non-working position and the inclined working position (Fig. 1). At the front end, the k-axis has a centering device either for the drill 25 having the drill head 26 or for the sacrificial rod 3 (FIG. k and 5). The sacrificial rod 3 has a shank 27 of reduced diameter forming the rear shoulder 28. A bracket 29 is attached to a guide opposite the centering device 30 and carries a sharp protrusion 31 for interacting with the wall of house 1, and a power cylinder (not shown) can be provided for moving guiding the longitudinal direction relative to the rack 21 to provide such an interaction. The perforator 13 has an ordinary forward protruding adapter 32 of the shank 27, onto which a jJ-junction sleeve 33 (Fig. 1) can be screwed, which, in turn, is in threaded connection with the drill 25. The transition nick 32 can alternately transmit the received blows from perforator 13 to shock bushing 3 (fig. k and 5, which in fig 1, was removed from the carriage 12 of the retrieved means, so that o6pa3OBatb has space for the earring 15. The impact bushing 34 (yig.) has 55
    the wife has two longitudinal holes coaxially in the longitudinal direction, one of which, slot 35, serves
    centered with respect to the corresponding holes 5B of the impact plug 53, the pin 59 can be locked in place 57 for the placement of the shank 36, and the other for the adapter 32 of the shank. The slot 35 has a bottom impact transfer surface 37 and expands conically in the outer direction with the formation of a socket 38 on the impact sleeve 3, and the opening 39 is open transversely to the outside of the sleeve 3 (Fig. 7) so as to enable the side adapter 32 to be inserted the shank when the shock sleeve 3 must be installed on the carriage 12 of the retrieving means. Hole 39 also forms the surface of the anvil AO at its bottom. parts. A transverse window 1, in which the lock is located in a lockable position, passes into slot 35 (Fig. 8). The locking screw on the sleeve 3 interacts with the groove on the locking 2 to prevent it from falling out of the transverse window (Fig. 6) and to provide access to the slot 35 (Fig. 5). Beveling allows constipation to be pulled to the side from this extended position as a result; inserting the shank 36 into the receptacle 35 into the position shown in FIG. 5. A downward-facing V-shaped leaf spring JU is suspended in brackets kj on the carriage 12. Under the action of gravity, the lock 42 is fed into the socket 35 in the position shown in FIG. 5, and in | 1 in FIG. 6, the constipation 42 is removed from this socket 35. The impact sleeve 34 has a neck 48 of reduced diameter with opposite locking pins 49. The carriage 12 of the extracting means, through which the driver carrier is screwed, carries a U-shaped bottom facing bracket 50, side elements 1 of which ends with right-angled downward protrusions 52. A fork 53 is installed between elements 54 and sits on each element 54 pairs of transversely directed protrusions 55. An L-shaped corner is attached to each element 54. 56, having a hole near its bottom element. These holes 57 are located coaxially and through holes 57 and 58, thus locking the impact plug 53 on the U-shaped bracket 50 and on the carriage 12. The plug 53 is designed to sit on the neck of the impact sleeve 3 Before inserting the locking pin 9, which is then selectively positioned along one of the neck flats B and thus fixing the impact sleeve 3 on the carriage in one of two positions. The centering device 30 (Fig. 13) is provided with a downwardly directed guide hole 60 of a rounded U-shape, about which two parallel axes 61 and 62, around which, respectively, guide 63 and locking 6 levers are rotatably mounted. The guide lever 63 has a guide hole b5 at the outer end and can occupy a displacement or grip position, shown by dash-dotted lines in fig. 1 and at the mouth of the guiding hole 6 or the position of the direction shown by the solid line located coaxially and closing the guiding hole 60 located below. The locking or locking lever 6 in this latter position under its own weight engages the outer end 66 of the guiding lever 63 by the protrusion b7 , as a result, the guide lever 63 is gripped and held in position on the board. Earring 68 is attached to a stopper arm and connected to an actuator / rod 69 or cable (not shown in detail), which is guided appropriately along the guide and stand 21 so that remote actuation can be performed from the operator’s console 70. in a safe position relative to the notch 2 and the drain channel (not shown) around it. The device works as follows. Suppose that the guides and the elements mounted on it occupy a safe position of lead or rotation relative to the blast, for example, an angular displacement of 90 or 180 relative to the position shown on the ball. 2. Immediately after sealing the notch 2 in the wall of the blast furnace 1, it is necessary 10 57 to cut the initial opening of a certain Length, in the still fresh mass of the embedment. For this purpose, if the impact sleeve 3 is still fixed in place in the carriage 12 of the removal device after the previous operation of removing and removing the sacrificial rod, the impact sleeve and fork 53 are removed and set aside after removing the locking pin 59. The threaded extension sleeve 33 of the drill 25, which carries the head 26, is attached to the adapter 32 of the shank, is rotated and receives blows of the punch 13. As shown in FIG. 1, the extension sleeve 33 takes up a position under the carriage 12 of the extraction device and is positioned freely with a gap between the elements 5 and the projections 52 of the U-shaped bracket 5P. With the aid of a conventional hydraulic remote control from the console 70, the guide k rotates around the vertical axis 23 of the column 21 to the angular position of the console 22 in FIG. 2 and then tilts by nagging around the axis 2A until the device occupies the position shown in FIG. 1. The initial hole to a depth of about 2/3 of that / ncini of the embedment material can be drilled with the remote control from the control panel 70. After the initial cutting, the guide C returns to its safe offset angular position using the console 22 and the extension sleeve 33 is manually disconnected from adapter 32 shank along with the drill 25 and the head 2b. Using a vertical upward movement, the impact sleeve 3, together with the garden of the impact fork 53, is then manually positioned in place in the bracket 50 of the carriage 12 of the extraction device, and the opening 39 of the impact sleeve 3 is in the position corresponding to FIG. 7 so that fitting the adapter 32 of the shank of the punch 13. The impact sleeve 3 is then manually rotated to the position corresponding to FIG. 6, in which the lock k2 comes out of the socket 35 under the influence of gravity, but the stopper is held. 7101
    screw Z. The locking pin 59 I is then installed JClivaets in place in the holes 57 and 5B (Fig, 10), resulting in an ocyuie that fixes the impact sleeve. and the impact fork 53 on the bracket 50 and, thus, on the carriage 12 of the extraction device. The shank 36 is set in place by hand by inserting it through the bell 38 into the socket 35 of the impact sleeve 3. Simultaneously, the outer end of the shank rises up into the guide hole b5 of the guide lever 63 on the centering device 30, and this lever initially takes the position shown dotted lines in FIG. 13. The lift continues until the expendable rod is centrally located in the main guide hole 60. At this point, the guide lever is locked by the lock lever 6k in the position shown by solid lines in FIG. 13.
    Using the remote control from the console 70, the Guide C then rotates around the vertical axis 23 of the rack 21 so as to face the wall of the blast furnace 1 and then again tilt down slightly around the horizontal axis 2k TaKj so that the rod is aligned with the newly drilled hole in the embedment The harvester 2. The rotary hammer 13 can now be remotely actuated and moved by moving together with the carriage 12 of the extraction device along the guide k, while the shank 36 is moved and laid. the remaining lower part of the wall in the initial hole of the embedment of the cell 2 during the movement and under the action of the impact force until this rod penetrates the molten metal in the inner part of the blast furnace 1. During this movement, the adapter of the shank rotating due to the integrated means of rotation of the perforator 13, can rotate freely in the hole 39 when hitting the anvil surface kQ.
    The shank 36 is then released from the centering device 30 by remote action from the Console 70, more accurately pulling the rod 6E (or cable) connected
    578
    with an earring 68. Thereafter, the guide A first tilts upwards and then is retracted back to the inoperative position. The shank remains in the fly, closing it and leaving it closed in the same way as the cap.
    Later, when the time comes to remove the sacrificial rod for
    opening the tap hole 3 after removing the locking pin 59 first rotates 180 in the plug 53 and the chip 50 until it takes up the position
    shown in FIG. The 5 "and locking pin 59 is then re-inserted in the same way as above. The guide l is again rotated and tilted to the working position by remote control from the control panel 70. A tilt around the horizontal axis 2k leads to the penetration of the bite of the bore and the guide holes 65 and 60 of the centering device
    and locking in such positions with the locking lever 64. By remote control from puff 70, the engine 6 falls forward in the direction of the blast carriage 12 of the extraction device until the shank of the expendable rod is seized by the socket 38 and is directed to the socket 35 by the bevel 5 of the locks 2 the bottom surface of the nest 35.
    The constipation k2 then rises into the transverse window k and then falls back under the combined action of its weight and displacement force of the leaf spring 46, thus locking the shank 36 at its rear shoulder at a time when the shank of the reduced diameter is located coaxially with the constipation k2. By remotely controlling the motor 6, the carriage 12 of the extraction device is moved back along the guide, while the perforator hits the adapter 32 of the shank 36 with the impact sleeve 3 At the surface of the anvil kQ in the hole 39 and with the lock at the bottom surface of the impact sleeve. As a result of this, the consumable rod is removed by the action of blows, as a result of which a tap hole for the flow of molten metal is opened. When the rail is pivoted and tilted to its inoperative position, the centering device 30 may be remotely actuated to release the consumable rod. The impact sleeve H can then be removed manually to prepare the tap-off opening device for subsequent identically carried out tap hole drilling, plugging it and the subsequent tap hole cycle.
    As can be seen from the above, all manual operations on the device are carried out in the idle position by the operator on a safe
    distance from the drainage trench and away from the -let.
    The positioning set includes a strut-mounted 21, obviously
    It can be replaced by another equivalent design, for example, a guiding lifting mechanism or a movable positioning means moving from one metallurgical furnace to another and forming a safe installation position near each of them that is sufficiently remote from the working position so that accidents are excluded.
