Description
lZ~2C~69 This device is constructéd for use on the charging car. A carrying member (9) is guided for vertical movement on a vertical guide (7) and carries a pivoting head (13) as the carrying member for a rotatable magnetic gripper (18) and a rotating charging hole frame cleaner (20). The pivoting head (13) is subs~ntially a channel-section cross-member, the magnetic gripper (18) and charging hole frame clRaner (20) being disposed on the outer limbs with their rotational axes preferably at right angles to one another, and the pivot axis (15) of the pivoting head (13) coincides with the angle bisector. By a simple 180 pivoting movement the charging hole frame cleaner (20) can be brought into the cleaning position instead of the magnetic gripper (18), and vice versa. Simultaneously with the cleaning of the charging hole frame (3), the removed charging hole cover (4) pivoted intc the cleaning position is cleaned by another cleaning tcol (23) rectilinearly movable on the carrying member (9). The magnetic gripper (18) and the charging hole frame cleaner (20) are disposed closely adjacent one another on the pivoting head and thus require rel~i~ely little free space for the common pivoting movements from one working position into the other.
(Fig. 1).
(Fig. 1).
- 2 - l~lZ~69 his invention relates to a device or removing and fitting the charging hole covers of horizontal chamber coke ovens and for cleaning the sealing surfacc~3, for use on the charging truck on which the device is disposed so as to be vertically reciprocable, the device having a rotatable magnetic gripper for engaging and retaining the cover and having a charging hole frame cleaner with a rotating cleaning tool, movable between a normal position and an operative position.
It is known to use a suitable device for mechanically opening, closing and cleaning the charging holes-of horizontal coke ovens. ~OS 30 16 418 shows a device of this kind which is relatively complex in construction and accordingly requires a very extensive amount of space for installation and operation. It is adapted to traverse along a support frame above the oven roof independently ox the charging car and other devices. In addition to occupying extra free space, this results in the access routes above the oven roof being blocked This is a considerable disadvantage to practical operation, because the extra installation of sensitive machinery and devices in the area at risk due to the heat requires rapid access for maintenance and repair work.
The object of the invention is to reduce the individual functions, such as lifting and fitting the charging hole cover and the cleaning of the sealing surfaces, to simple movements which can be performed in the minimum amount of space, so that these functions ~Z~69 can be performed with a compact-construction device using operationally dependable equipment and components which are easily accessible so-that any maintenance and repair work can be carried out rapidly and without difficulty. Another object of the invention is so to devise the equipment that it can be installed on the charging car without any difficulty and is adapted to traverse above the oven roof with the charging car.
In a device of the kind referred to hereinbefore, `to this end, according to the invention, the magnetic gripper and the charging hole frame cleaner are disposed on a pivoting head on opposite sides of the pivot axis with their rotational axes disposed at an angle to one another in coplanar relationship, the pivot axis of the pivoting head being disposed in such plane and coinciding with the bisector of the angle formed by the two rotational axes; and the pïvoting head is mounted on a carrying member guided for vertical movement on a vertical guide.
The angle between the two axes of rotation is preferably 90 . Advantageously, the pivoting head is substantially a channel-section cross-member, the magnetic gripper and the charging hole frame cleaner being so disposed on the outer limbs that the magnetic gripper and the charging hole frame cleaner are disposed on an outside of the limbs.
In another aspect of the inven~on, for cleaning the sealing surfaces of the charging hole cover, on the _ 4 69 carrying member a cleaning element centred on the rotational axis ox the magnetic gripper with the same in its normal position is disposed on a slide adapted to reciprocate in the direction of the latter rotational axis.
With the two rotating elements, such as the magnetic gripper and the charging hole frame cleaner, it is possible to provide two separate drives or a common drive operating via a transmission.
According to another aspect of the invention, the charging hole frame caner is combined with a rotating tool for cleaning the charging shaft, the said tool being in the form of brushes or scrapers for example.
One of the main advantages of the invention is that the magnetic gripper and the charging hole frame cleaner, i.e. the elements which are required to be alternately positioned in an operative position centrally with respect to the charging hole, are disposed on a common pivoting head, so that it is possible for the required working movements to be performed by simple rotational movements. it the same time, these two elements can be disposed adjacent one another in a restricted amount of spaceO This results in a compact construction and also has the advantage that relatively little sac is occupied for the working movements of the components.
Another advantage is that during the cleaning of the sealing surfaces of the charging hole it is also possible to clean the charging hole cover at its sealing surfaces. For this purpose, another cleaning element - 5-l~lZO69 is provided, which is disposed on a slide and performs a rectilinear working mo,vement. This slide together with the pivoting head is mounted on the same carrying member, so that there is no need for any additional client between the charging hole cover and the cleaning element. The rotating charging hole frame cleaner may ye combined with another tool for cleaning the filling shaft.
Exemplified embodiments of the invention are `illustrated in the drawing in diagrammatic form and are explained in detail below.
Fig. 1 is a side elevation of the device in a posiiion above a charging hole.
Fig. 2 is a side elevation of a device corresponding to Fig. 1 but with an integrated drive for the magnetic gripper and the charging hole frame cleaner.
Fig. 3 is a side elevation of the device of Fig. 2, the pivoting head having been pivoted through 90.
Fig. 4 is a plan view of the device according to Fig. 3 and a section on the line I-I, and ; Fig. 5 is a detail of a charging hole frame cleaner combined with a tool for cleaning the filling shaft.
Referring to the drawing, the roof or crown 1 of a coke oven is illustrated in cross-section along the central plane of a charging hole 2. The top of the charging hole 2 is flush with the circular charging hole frame 3, which is used to mount the charging hole cover 4. The sealing surface 5 of the frame and the corresponding sealing surface 6 of the cover 4 are in the form of conical surfaces.
- 6 ~120~9 A charging car (not shown) is adapted to traverse longitudinally of the oven battery above the root 1 on rails and during chamber charging occupies a position such that the coal can flow via a charging hopper into the open charging hole therebeneath. The charging hole cover is lifted and subsequently fitted mechanically by means of the device described in detail below.
The device is guided for vertical movement on a vertical carrying frame, the top end of which is rigidly secured to the charging car frame structure. The carrying frame consists basically of two U-sections 7, which are disposed with the open sides facing one another and the limbs of which serve as guide rails for the rollers 8 of a carrying member 9.
The latter consists of a ho~zontal main member 10, the rear end of which passes through the U-sections 7, and an attachment 11 situated thereabove. Of the total of four guide rollers, one pair is mounted for rotation on the main member 10 and the second pair on the member 11, the rollers being rotatable about a horizontal axis in each case. The carrying member 9 is lifted and lowered by a drive (not shown) which may consist of a hydraulically or pneum,atically operated actuating cylinder or an electric mo,tor with a gear for producing a linear movement.
As will be apparent from Fig. 3, the carrying frame is enclosed in a protective casing 12, which abuts the outsides of the U-sections 7, is open on one side for the up and down movement of the member 9, and seals off the interior on the other thres sides.
_ 7 _ 1 2 6 9 A pivoting head 13 is mounted at the free end of the cantilevered main member 10, on a pivoting shaft 14 which projects from the main member 10 and the pivot axis 15 of which extends in a vertical transverse plane to the longitudinal axis of the oven battery with an inclination of 45 to the horizontal.
The pivoting head 13 is substantially in the form of a cross-member having an approximately channel-section profile, the two equal-length limbs 16, 17 being rigidly secured at the ends of the central part -which forms the base of the channel - with an inclination of 45, so that the two limbs 16 and 17 are at right angles to one anotherD Limb 17 forms the holder for a known rotatable magnetic gripper l for engaging and holding the charging hole cover 4. This magnetic gripper is on the outside of the limb 16 and is driven by a separate drive 19 flanged on the inside, e.g. an electric motor with an associated reduction geaxO
The other limb 17 of the head 13 is used to mount a rotating tool 20 for cleaning the seat surface of the charging hole frame 3. A separate drive 21 is flanged on the inside of the limb 17 in the same way as in the case of limb 16 and delivers the rotational energy for the cleaning tool 20.
A horizontally traversable slide 22 is disposed in the member 11 and on its side facing the pivoting head 13 bears a cleaning tool 23 which may, for example, be in the form of brushes or mechanical scrapers for cleaning the sealing surface of the cover 4. During the cleaning operation the cover 4 is rotated by the l~Z~)65 -drive 19 and the cleaning tool 23 is pressed by means of the slide 22 against the sealing surface for cleaning, the pivoting head 13 having previously been pivoted into the cleaning position with the cover 4 removed.
Fig.2 shows an embodiment which is modified in respect of the drives for the magnetic gripper 18 and the charging hole frame cleaner 20. In this case theee two elements are connected to a centre drive via a transmission inside the pivoting head 13, such drive being disposed in the pivoting head 13 or in the carrying member 9.
The charging hole frame cleaner 20 may be equipped with another tool 24, e.g. in the form of a cylindrical brush, for cleaning the charging shaft beneath the charging hole frame 3 (Fig. 5~. With a tool of this kind it is possible to clean the charginy hole frame 3 and the charging shaft in one operation.
The device operates as follows:
The device occupies the cleaning position above a charging hole 2;
The carrying member is lowered to lower the magnetic gripper 16 on to the charging hole cover 4, The magnet is switched on and the charging hole cover 4 is rotated by moans of drive 19;
Carrying member 9 moves upwards, The pivoting head 13, 13a is pivoted so that the charging hole frame cleaner 20 occupies the position of the magnetic gripper 18 and vice-versa;
Carrying member 9 i9 lowered until the charging hole frame cleaner 20 i5 in contact with the sealing surface 5 of the charging hole frame 3, .;
At the same time, the cleaning tool 23 is brought by the slide 22 into a position in front of the rotating charging hole cover 4 and the sealing surface of the ; latter is cleaned, The cleaning tool 23 moves back, the pivoting head 13, 13a is pivoted back into the initiaL position;
he charging hole cover 4 is re-fitted on the charging hole frame 3 and rotated into the closed position by the working movement of the carrying member 9, and - The magnet is switched off and the carrying member 9 moved upwards.
