The invention relates to a coke extraction device for coke ramps which can be moved along the coke ramp Räumwagen for withdrawing the coke from the coke ramp onto one or more conveyor belts and with Temperature sensors and post-extinguishing devices for the coke lying on the conveyor belts.

For such coke extraction devices on coke ramps, coke belongs to the state of the art by means of a clearing car that can be moved along the entire coke ramp with a clearing wheel that revolves around a vertical axis rotates, to be pulled evenly from the coke ramp onto a conveyor belt. the Power supply for such a clearing vehicle is done via a power cable, which is during the process of the The clearing car rolls up and down on a cable reel along the coke ramp. Especially at seTir long Coke ramps, which can have a length of more than 50 m, always occur with such cable drums again to disturbances when winding and unwinding the cable. You also need for larger systems Cable drums with considerable dimensions, which can lead to space problems.

The use of electrical conductor rails has grown not proven because of the risk of pollution and the humid atmosphere

For the power supply along the coke oven battery movable control car, it is known only that Suspend the power cable on a track as a trailing cable. In the embodiment according to JP 52-91 003, for example, the power cable for a Coke ramp movable emission hood guided in such a way The application is here limited to one power cable. Nothing is evident about the supply and discharge of other media.

From the P 33 39 160 it is known, on its own, Above the coke ramp movable car facilities for measuring the temperature of the coke ramp to arrange lying coke and for targeted post-extinguishing of the coke. To feed the electrical Stream and in particular the extinguishing water from a stationary connection to the movable car it is known from this document to also arrange the flexible connecting lines on a drum. Alternatively, the water supply should be via a water channel arranged along the coke ramp and a pump installed on the trolley.

The object of the invention is now to better guide the flexible connecting lines from the stationary one To propose connection to the clearing vehicle, which requires less space and works reliably.

According to the invention, this object is achieved by the characterizing part of the main claim. The subclaims are useful embodiments of the invention.

By arranging temperature sensors and post-extinguishing devices directly on the clearing vehicle The post-extinguishing device can be used immediately when any still glowing coke parts hit the conveyor belt be put into operation. You can also control the clearing car so that it is automatic stops when there is a measurement signal about excessively high temperatures, or briefly moves back and forth until the coke is extinguished. For the transmission, especially the extinguishing water and any compressed air that may be required as well as the electrical current and the measuring pulses, from the stationary connections to the clearing vehicle the invention provides that the individual lines as trailing lines along the coke ramp at a plurality are suspended in a loop by holding brackets on one or more running rails. So that will next to the conveyor belt along the coke ramp, only a narrow space is required for the trailing cables, and the clearing vehicle automatically pulls the trailing cables behind it without any additional drive. aside from that are pulled apart and together

pushing the individual loops of the trailing cables this is only very slightly bent, so that the mechanical The stress on the individual lines remains low.

According to the invention, the various trailing cables required can cross over next to or on top of one another each have a common retaining bracket suspended from the running rail. Thereby are along the conveyor belt the tie bars! only arranged one behind the other, and only one type of retaining bracket is required, which are also only attached to a running rail. According to the invention, the Haitebü rests! of the trailing cables Can be pushed together in one or two storage spaces at the end of the running rail outside the conveyor belt be. In particular, there is also a separation of the trailing cables for the electrical current and the measuring pulses of those for extinguishing water and possibly compressed air are possible in such a way that they are each in a storage space are collapsible at the ends of the conveyor belt. Such a measure is also off Advantageous for security reasons

When arranging two clearing wheels over a conveyor belt, with one clearing wheel as a reserve is available, it is convenient to use the trailing cables for both clearing vehicles to be hung on a running rail and in a storage space at both ends of the Make the conveyor belt collapsible. In this case, too, it will be along the conveyor belt requires considerably less space

When arranging a clearing table below the coke ramp for the two-sided withdrawal of the coke According to the invention, two conveyor belts running parallel to one another can also be in the middle of the broaching table a continuous, upwardly tapering saddle for the guidance of the coke stream and uniform Distribution to the respective side of the scraper table that is in operation.

This saddle running in the middle of the room table ensures that the side of the broaching table that is in operation is applied evenly. Through this Guide is also slowed down the falling coke and thus prevents individual coke pieces fall over the ramp table. Furthermore, a precise separation between both sides is achieved in the admission and thus ensures that the entire Coke is caught by the clearing truck. In addition, with this arrangement, the coke cannot move the clearing wheel to be pushed away to the opposite side of the clearing table; thus the removal is the entire Koksschüttunj ensured by the clearing wheel

This saddle in the middle of the broaching table is expediently covered with a wear-resistant covering, e.g. B. ceramic plates, designed and fastened in a special way with an interior profile made of iron material.

The towing lines proposed according to the invention for the supply of the Räunvwagens can also be used for a z. B. from P 33 39 160 known, above the coke ramp movable car with devices for measuring the temperature of the coke lying on the coke ramp and for targeted post-extinguishing of the coke.

The invention is illustrated by means of FIGS. 1 to 8 explained in more detail, for example
