Description

(54) COKE OVEN SERVICING MACHINES (71) We, NORTHERN ENGINEER ING INDUSTRIES LIMITED, a British Company of NEI House, Regent Centre, Newcastle-upon-Tyne, NE3 3SB, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The invention relates to coke oven servicing machines.
With known coke oven servicing machines, it is necessary to re-position the machine as a whole after the oven door has been removed in order to discharge coke; and to re-position the machine as a whole in order to clean the oven door frame; and to replace the door.
An object of the invention is to provide a servicing machine by which an oven door may be removed, coke discharged, the door frame cleaned and the door replaced without the need to re-position the machine as a whole.
Such an operation may be referred to as a "single spot" operation, since once the machine is positioned opposite the oven door, there is no need to re-position the machine as a whole to effect the various service functions. The machine moves on to the next oven when the functions have been performed.
A coke oven servicing machine, according to the invention, comprises a main structure, on which there is mounted an oven door cleaner, a subsidiary structure which is at most only partly supported by the main structure and on which servicing mechanisms including a door extractor and a door frame cleaner are mounted so as to be advanceable in the same sense along respective spacedapart parallel lines of movement and to be retractable also therealong and mechanism which interconnects the structures and which is operable to move the subsidiary structure rectilinearly transversely of said line of movement into servicing positions including a position in which the door extractor is aligned with the door cleaner.
Preferably, said means is arranged for movement entirely within the overall length of the machine.
Preferably, said means is arranged partly or wholly within the machine.
Preferably, said means is at least partly supported on wheels independently of the machine.
Said mechanism is preferably a hydraulic ram mechanism having a piston part and a cylinder part, one part being connected to said means, and the other part to the machine. A plurality of mechanisms may be used. Two hydraulic cylinders may receive pistons joined by a common piston rod.
Alternatively, the mechanism may be a screw-and-nut mechanism; or a rack-andpinion mechanism; or a lever mechanism; or a cable-operble mechanism; or some other kind of fluid operable mechanism; and the mechanism may be a hand-operable mechanism.
An example of a coke oven servicing machine will now be described to illustrate the invention with reference to the accompanying drawings, in which: Figures 1 to 3 are schematic plans of a coke oven installation showing the machine in three different stages of operation; and Figure 4 is a schematic vertical section at IV in Figure 3.
The drawings show a coke oven having a door opening 12 having a centre-line 13; and a door 14. Bench rails 16 run along in front of the oven (which is one of a battery of ovens) and a self-propelled coke oven servicing machine 18 is mounted on wheels 20 running on the rails 16.
The machine 18 carries an oven door cleaner 22 having a centre-line 24.
The main structure of the machine 18 is in the form of a horizontal open frame having an opening 26 within which there is accommodated a subsidiary structure 30 comprising a carriage 32 supported on four wheels 34 running on the rails 16.
The machine 18 further comprises hydraulic ram mechanism including two hydraulic cylinders 40, 42 secured to the frame of the machine 18 and the carriage 32, respectively. The cylinders 40, 42 contain pistons connected to opposite ends of a common piston rod 44.
The carriage 32 is arranged wholly within the overall length of the frame of the machine 18 and for movement lengthwise of the machine 18 wholly within the overall length of the machine 18 by operation of the hydraulic ram mechanism as explained below.
The frame of the machine 18 and the carriage 32 each have brakes (not shown) acting on the wheels 20, 34. A driver's position (not shown) is provided on the frame of the machine 18.
The carriage 32 carries a door extractor 50; a door frame cleaner 52; and a coke guide 54 hich are advanceable in the same sense along spaced apart parallel lines, and retractable, transversely of the carriage by hydraulic actuator or other means not shown. Those mechanisms have horizontal centre-lines, 56, 58 and 60, respectively (Figure 1) along which they are advanceable and retractable. Also, the door cleaner centre-line 24 is positioned such that when the door-extractor centre-line 56 is co-linear with the door-cleaner centre-line 24, the coke-guide centre-line 60 is co-linear with the oven door opening centre-line 13.
Operation Figure 1 shows the machine 18 having been brought to a position opposite an oven with the carriage 32 in its extreme rightward position in relation to the machine 18 so as to align the centre-line 56 of the door extractor 50 with the axis 13 of the oven door opening.
The machine 18 is braked at that position and the door extractor 50 is advanced into engagement with the door 14 and retracted to remove the door 14 to the position indicated in ghost outline at 70.
The ram mechanism 40,42,44 is operated to move the carriage 32 leftward to align the door-extractor centre-line 56 with the doorcleaner centre-line 24 and, simultaneously, to align the coke-guide centre-line 60 with the oven opening axis 13.
The guide 54 is advanced and coke is discharged by a ram indicator at 80 in ghost outline into a coke car (not shown) on a separate rail track (Figure 2).
At the same time the door extractor 50 advances the door 14 into engagement with the cleaner 22, which is operated to clean the door 14 (Figure 2).
After completion of coke discharge, the guide 54 and the door extractor 50 are both retracted.
The hydraulic ram mechanism is operated to move the carriage 32 rightward to align the centre-line of the door frame cleaner 52 with the oven opening axis 13.
The cleaner 52 is advanced, traversed around the frame to clean it (Figure 3) and then retracted.
The hydraulic mechanism is operated to move the carriage 32 rightward again to align the door-extractor axis 56 with the door opening axis 13.
The door extractor 50 is advanced to replace the door 14 in the opening 12 and the door-extractor 50 retracts.
The machine 18 is then ready to move along the rails 16 to the next oven to be serviced.
The movements of the carriage 32 under the action of the ram mechanism 40, 42, 44 are precise indexing movements and are precisely repeatable, so that the machine operator merely has to push a button to initiate each indexing movement of the carriage and does not have to control the speed or extent of the carriage movement. Alignment of.the mechanism on the carriage with the oven door opening 12 is thus automatically effected.
The machine is suitable for use in installations in which a hood is provided over a quenching car into which the coke is passed.
In a modification (not shown) the carriage 32 may be arranged only partly within the overall length of the frame of the machine 18; and may be arranged for movement only partly within the overall length of the frame.
WHAT WE CLAIM IS: 1. A coke oven servicing machine comprising a main structure, on which there is mounted an oven door cleaner, a subsidiary structure which is at most only partly supported by the main structure and on which servicing mechanisms including a door extractor and a door frame cleaner are mounted so as to be advanceable in the same sense along respective spaced apart parallel lines of movement and to be retractable also therealong, and mechanism which interconnects the structures and which is operable to move the subsidiary structure rectilinearly transversely of said lines of movement into servicing positions including a position in which the door extractor is aligned with the door cleaner.
2. A machine according to claim 1, in which the subsidiary-structure is arranged for movement at least partly within the overall length of the machine.
3. A machine according to claim 2, in which the subsidiary structure is arranged for movement entirely within the overall length of the machine.

**WARNING** start of CLMS field may overlap end of DESC **. the form of a horizontal open frame having an opening 26 within which there is accommodated a subsidiary structure 30 comprising a carriage 32 supported on four wheels 34 running on the rails 16. The machine 18 further comprises hydraulic ram mechanism including two hydraulic cylinders 40, 42 secured to the frame of the machine 18 and the carriage 32, respectively. The cylinders 40, 42 contain pistons connected to opposite ends of a common piston rod 44. The carriage 32 is arranged wholly within the overall length of the frame of the machine 18 and for movement lengthwise of the machine 18 wholly within the overall length of the machine 18 by operation of the hydraulic ram mechanism as explained below. The frame of the machine 18 and the carriage 32 each have brakes (not shown) acting on the wheels 20, 34. A driver's position (not shown) is provided on the frame of the machine 18. The carriage 32 carries a door extractor 50; a door frame cleaner 52; and a coke guide 54 hich are advanceable in the same sense along spaced apart parallel lines, and retractable, transversely of the carriage by hydraulic actuator or other means not shown. Those mechanisms have horizontal centre-lines, 56, 58 and 60, respectively (Figure 1) along which they are advanceable and retractable. Also, the door cleaner centre-line 24 is positioned such that when the door-extractor centre-line 56 is co-linear with the door-cleaner centre-line 24, the coke-guide centre-line 60 is co-linear with the oven door opening centre-line 13. Operation Figure 1 shows the machine 18 having been brought to a position opposite an oven with the carriage 32 in its extreme rightward position in relation to the machine 18 so as to align the centre-line 56 of the door extractor 50 with the axis 13 of the oven door opening. The machine 18 is braked at that position and the door extractor 50 is advanced into engagement with the door 14 and retracted to remove the door 14 to the position indicated in ghost outline at 70. The ram mechanism 40,42,44 is operated to move the carriage 32 leftward to align the door-extractor centre-line 56 with the doorcleaner centre-line 24 and, simultaneously, to align the coke-guide centre-line 60 with the oven opening axis 13. The guide 54 is advanced and coke is discharged by a ram indicator at 80 in ghost outline into a coke car (not shown) on a separate rail track (Figure 2). At the same time the door extractor 50 advances the door 14 into engagement with the cleaner 22, which is operated to clean the door 14 (Figure 2). After completion of coke discharge, the guide 54 and the door extractor 50 are both retracted. The hydraulic ram mechanism is operated to move the carriage 32 rightward to align the centre-line of the door frame cleaner 52 with the oven opening axis 13. The cleaner 52 is advanced, traversed around the frame to clean it (Figure 3) and then retracted. The hydraulic mechanism is operated to move the carriage 32 rightward again to align the door-extractor axis 56 with the door opening axis 13. The door extractor 50 is advanced to replace the door 14 in the opening 12 and the door-extractor 50 retracts. The machine 18 is then ready to move along the rails 16 to the next oven to be serviced. The movements of the carriage 32 under the action of the ram mechanism 40, 42, 44 are precise indexing movements and are precisely repeatable, so that the machine operator merely has to push a button to initiate each indexing movement of the carriage and does not have to control the speed or extent of the carriage movement. Alignment of.the mechanism on the carriage with the oven door opening 12 is thus automatically effected. The machine is suitable for use in installations in which a hood is provided over a quenching car into which the coke is passed. In a modification (not shown) the carriage 32 may be arranged only partly within the overall length of the frame of the machine 18; and may be arranged for movement only partly within the overall length of the frame. WHAT WE CLAIM IS:
