Abstract
A projectable device for aligning rail mounted equipment with track side structures, and, in particular, for aligning a coke oven door extractor, pusher ram, or jamb cleaner with a coke oven door. In one embodiment, a rod having an attached terminal fork is extended horizontally toward the door so as to indicate alignment when an attached aligning plae is engaged by the fork. The rod projects from a piston and cylinder combination, and it is automatically withdrawn if alignment is correct. In a second embodiment, an arm having an attached terminal fork is swung downwardly in a vertical arc to engage the aligning plate and thereafter automatically returned to its initial, vertical position, if alignment is correct.
Claims16
A device for aligning rail mounted equipment with a track-side structure comprising:
- (a) a piston and cylinder combination having a rod projecting from the piston toward the track-side structure and having at the terminal end of said rod an aligning projection which is engageable with an aligning plate mounted adjacent the track-side structure;
- (b) means for expanding said piston and cylinder combination so as to extend the rod to a point where the aligning projection engages the aligning plate;
- (c) means for compressing said piston and cylinder combination so as to withdraw the rod from the point where the aligning projection engages the aligning plate;
- (d) control means for alternatively activating either said means for expanding the piston and cylinder combination or said means for compressing said piston and cylinder combination;
- (e) a limit switch connection with said control means such that said means for compressing the piston and cylinder combination is activated when said limit switch is tripped;
- and
- (f) a limit switch operating bar mounted adjacent said rod so as to be moveable therewith and having thereon a rearward trip positioned so as to trip the limit switch as the aligning projection engages the aligning plate, such that after the means for expanding the piston and cylinder combination have been employed to extend the rod to the point where the aligning projection engages the aligning plate, the means for compressing said piston and cylinder combination will then withdraw the rod.
A device for aligning rail mounted equipment with a track-side structure comprising:
- (a) a hydraulic piston and cylinder combination having a rod projecting from the piston toward the track-side structure and having at the terminal end of said rod an aligning projection which is engageable with an aligning plate mounted adjacent to the track-side structure;
- (b) a hydraulic fluid pressure source;
- (c) a rearward hydraulic line connected at one end of the piston and cylinder combination so as to expand said piston and cylinder combination when connected at its other end to the hydraulic fluid pressure source;
- (d) a forward hydraulic line connected at one end to the piston and cylinder combination so as to compress said piston and cylinder combination when connected at its other end to the hydraulic fluid pressure source;
- (e) a selector valve positionable by a solenoid and having a first position which connects the rearward hydraulic line to the hydraulic pressure source when the solenoid is in one state of activation and a second position which connects the forward hydraulic line to the hydraulic pressure source when the solenoid is in the other state of activation;
- (f) a limit switch connected in electrical circuit with a power source and said solenoid such that the state of activation of the solenoid is changed when the limit switch is tripped;
- and
- (g) a limit switch operating bar mounted adjacent the rod so as to be moveable therewith and having thereon a rearward trip positioned so as to trip the limit switch as the aligning projection engages the aligning plate, such that after the selector valve has been initially positioned in its first position so as to expand the piston and cylinder combination and extend the rod to a point where the aligning projection engages the aligning plate, the selector valve will then be positioned in its second position so as to withdraw the rod.
