Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lifting and unloading device for a coke oven coal car.

The purpose of this is to obtain a device for lifting and unloading coal loading cars that runs on the top surface of a coke oven, so that repair of coal loading cars can be carried out reliably and efficiently on the ground, which is advantageous. .

Traditionally, when repairing a coal loading car, it was guided to the edge of the top of the furnace, but there was a problem in transporting repair equipment from the ground to the top of the furnace, and the top of the furnace was blown up by the coal loading process. The disadvantage was that repair work was difficult and could not be carried out efficiently due to the harsh environment where it was exposed to coal dust.

The present invention is intended to improve this, and to explain in detail with reference to the attached embodiment drawings below, there are four screw shafts (threaded on the circumferential surface) between the above-ground part 3 and the furnace top surface 2 at the end of the coke oven 1. 8 vertically installed at the four corners. Each screw shaft has a separately installed motor 9, a speed reducer 10, and a gear 12 that meshes with a worm 11, so that it can rotate forward and backward at the same speed. A screw cylinder 13 is screwed into each screw shaft 8, and the lifting table 4 is vertically moved up and down by forward and reverse rotation of the screw shaft 8. Rails 14, 14' are laid on the lifting table 4, and a trolley 7 for lifting and lowering the coal loading car 6 is mounted on the rails 14, 14' with wheels 15 on the lower surface.

Rails 17, 17' are provided on the truck 7 to butt and communicate with running rails 16, 16' of the coal loading car 6.

In the figure, reference numeral 18 denotes a side post vertically arranged parallel to the outside of each screw shaft 8, and the rollers 20 of the guide member 19 attached to the outside of each screw tube 13 are brought into face-to-face contact with the side post 18. Further, 21 and 22 are reinforcing columns provided on the outside parallel to the coke oven 1 side.
3 is a brace, and 24 is a walkway. Also,
5 and 5' are connecting rails installed on the ground.

With the above configuration, when the coal loading car 6 that was loading coal on the top of the furnace breaks down and requires repair, each motor 9 is operated to rotate each screw shaft in the forward direction, for example. vertically move the lifting table 4 up and down to align the cart 7 with the furnace top surface 2, and
7, 17' are butt-connected to the running rails 16, 16', the coal loading car 6 is transferred onto the trolley 7, each screw shaft 8 is rotated in the opposite direction, the lifting table 4 is lowered to the ground level 2, and the rail 14, 14' are aligned with the connecting rails 5, 5' on the ground, and the trolley 7 on which the coal loading car 6 has been transferred is moved by a winch or the like and guided onto the connecting rails 5, 5' on the ground. The coal loading car 6 which has been repaired on the ground is returned to the lifting table 4 along with the cart 7, and is returned onto the furnace top surface 2 by the upward movement of the table 4.

In this way, the present invention allows repair work to be carried out on the coal loading car on the ground where repair materials etc. can be easily procured in a favorable environment by installing the unloading device for the coal loading car at the hearth. This has the effect of making the repair work more reliable and efficient.
