I COMBINED COKE OVEN DOOR JAMB CLEANING APPARATUS AND DOOR HANDLING APPARATUS Filed March 4, 1969 PIE: 1

United States Patent C) U.S. Cl. 202-241 4 Claims ABSTRACT OF THE DISCLOSURE A coke oven pusher machine has a supporting arm eX- tending therefrom and movable longitudinally toward and away from the coke oven chamber. A connecting member is pivotally secured to the end of the supporting arm and has door jamb cleaning apparatus and door handling apparatus secured thereto in angular spaced relation to each other. A suitable drive means `is provided to pivot the connecting member relative to the end of the supporting arm to position either the door jamb cleaning apparatus or the door handling apparatus in operative position with the coke oven door jamb. With this arrangement, the coke oven door jamb can be cleaned and the coke oven door rcplaced without moving the pusher machine.

BACKGROUND OF THE INVENTION (1) Field of the invention This invention relates to a combined coke oven door jamb cleaning apparatus and door handling apparatus and more particularly to a support member that pivotally supports both the door jamb cleaning apparatus and the door handling apparatus from a common supporting arm.

(2) Description of the prior art In horizontal by-product coke ovens, the coke oven chambers are sealed at their opposite ends by coke oven doors. On the machine side of the coke oven battery, a pusher machine includes separate apparatus to remove and support the coke oven door, push the charge of coke and level a new charge of coal to be coked. Separate apparatus is provided to clean the door jamb before the door is replaced. When space conditions between the coke oven battery and the front portion of the retracted pushing ram permit, the door jamb cleaning apparatus is moved into position between the coke oven battery and the coke pusher machine without moving the pusher machine. Where, however, the space conditions on the machine side of the coke oven are limited, the pusher machine must be moved away from the coke oven chamber after the pushing operation to provide room for positioning the door jamb cleaning lapparatus in operative position. This increases .the total operating time required to push the charge of coke, clean the door jamb and recharge the oven with coal to be coked.

There have been proposals in the past to combine the coke oven door jamb cleaning apparatus with the pusher ram. With this arrangement, the coke is first pushed from 3,577,321 Patented May 4, 1971 the coke oven by the pusher ram and then the coke oven door jamb cleaning device removes the carbonaceous material from the door jamb so that the door may be replaced to effectively seal the coke oven chamber. The door that is removed from the coke oven is separately supported on a door lifting head of the door handling apparatus and the pusher machine is then moved laterally to move the door handling apparatus into position to reposition the coke oven door. There is a need for apparatus that eliminates the movement of the pusher machine during the door jamb cleaning operation and the reposi-tioning of the coke oven door in sealing relation with the coke oven chamber.

The hereinafter described invention relates to a combined door jamb cleaning apparatus and door handling apparatus that are angularly secured to a common connecting member. The connecting member is pivotally secured to a support arm that is movable longitudinally relative to the coke oven chamber. The door jamb cleaning apparatus is positioned at an angle of about to the door handling apparatus and the connecting member is pivotally secured to the support arm. After the coke has been pushed from the coke oven chamber by the pusher ram, the pusher machine is moved laterally to the coke oven chamber until the door jamb cleaning apparatus is aligned with the empty coke oven chamber. The supporting arm moves longitudinally toward the coke oven chamber and position the door jamb cleaning apparatus in operative position to remove the carbonaceous material from the door jamb. After the cleaning operation is completed, the support arm is retracted away from the coke oven chamber and the connecting member is pivoted about a vertical pivot axis to move the door handling apparatus into aligned relation with the coke oven chamber. The support arm is then advanced toward the coke oven chamber and the door is positioned in the door jamb and secured therein. With this arrangement, the door jamb cleaning apparatus cleans the door jamb and the door is repositioned in the door jamb without moving the coke pusher machine. It is, therefore, no longer necessary to move the coke pusher machine during the cleaning of the door jamb and the replacing of the coke oven door.

Accordingly, 4the principal object of this invention is to provide apparatus for cleaning the coke oven door jamb and replacing the coke oven door without moving the pusher machine.

Another object of this invention is to provide a coke pusher machine with apparatus for angularly connecting the door jamb cleaning apparatus and the door handling apparatus and pivotally securing the connected apparatus to a longitudinally movable supporting arm tha-t forms a part of the pushing machine.

These and other objects and advantages of this invention will be more completely disclosed and described in the following specification, the accompanying drawings and the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. l is a fragmentary schema-tic plan view of the machine side of a horizontal coke oven battery, partially in section, with the pusher machine positioned adjacent thereto and illustrating the door jamb cleaning apparatus in operative position to clean the door jamb.

FIG. 2 is a view similar to FIG. l illustrating the door handling apparatus in position to replace the coke oven door.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, a fragmentary portion of the pusher side of a coke oven is generally designated by the numeral and includes a plurality of horizontal coking chambers 12 with heating walls 14 therebetween. Buckstays 16 extend vertically on opposite sides of the coke oven chambers 12 along the pusher side wall. Coke oven doors designated by the numeral 18 are positioned in abutting relation with rectangular door jambs 20 to seal the coke oven chambers 12 during the coking operation.

A pusher machine generally designated by the numeral 22 is mounted on rails 24 and is operable to move along the machine side of the coke oven 10. The pusher machine 22 includes a leveling bar 26, a pusher ram 28 and a support member 30 .to -which a connecting member 32 is pivotally secured. The connecting member 32 has a door jamb cleaning device 34 and a door handling device 36 secured thereto. The door jamb cleaning device may be of conventional construction similar to that illus- -trated in U.S. Pat. 2,391,214 or U.S. Pat. 3,119,135.

The door handling apparatus 36 includes a door lifting head 38 which is operable to be connected to the coke oven door 18 and unlatch and remove the door from the door jamb 20. The door handling apparatus 36 secured to the connecting member 32 may also be of conventional construction, as for example, the door handling devicex illustrated in US. Pat. 2,391,214.

The connecting member 32 is pivotally secured to the support member 30- about a vertical pivot pin 40. Suitable drive means, not illustrated, is provided to pivot the connecting member 32 about the axis of pivot pin 40 to thereby position either the door jamb cleaning device 34 or the door handling device 36 in operative aligned relation with the coke oven chamber 12. The support member 30 has a trolley 42 with trolley wheels 44 suitabily supported on rails 46 on the pusher machine 22. Other suitable drive means are provided to reciprocate and move the support member 30 toward and away from the coke oven chambers 12 by means of the trolley 42.

With the above door jamb cleaning device 34 and door handling device 36 secured to the connecting member 32 and extending therefrom at an angle of about 90 to each other, it is now possible to clean the coke oven door jamb 20 and replace the coke oven door 18 without moving the pusher machine 22 on the rails 24.

After pushing the coke from the coke oven chamber 12 by the pusher ram 28, the pusher machine 22 is moved to the position illustrated in FIG. 1, opposite the empty coking chamber 12. The pusher machine 22 is moved along the rails 24 until the axis of the support member 30 is aligned with the axis of the empty coking chamber 12. The supporting member 30 is in a retracted position where both the door'jamb cleaning device 34 and the door handling device 36` are spaced rearwardly from the buckstays 16. When the support member 30 is aligned with the coke oven chamber 12, a drive means is actuated to rotate the connecting member 32 about the axis of pivot pin 40 to align the door jamb cleaning device 34 with the coke oven chamber 12 as is illustrated in FIG. 1. The support member 30 is then moved toward the coke oven chamber 12 until the door jamb cleaning device is in operative position as illustrated in FIG. 1 to remove the carbonaceous residue from the door jamb 20. After the door jamb 20` has been cleaned by the door jamb cleaning device 34, the support member 30 is retracted as is illustrated in FIG. 2 and the connecting member 32 rotated about the pivot pin 40 to align the door handling device 36 with the coke oven chamber 12. The support member 30 is then advanced along the rails 46 to bring the door 18 into abutting relation with the door jamb 20 and the door is then locked in position. With the above described apparatus the time consuming operation of moving the coke pusher machine 22 along the rails 24 during the door jamb cleaning operation and thereafter repositioning the pusher machine 22 to replace the door 18 has been eliminated.
