Abstract

On a guide rail movable co planer whose guide claw is lockably connected to an exchangeable U-shaped guide piece in longitudinal direction and vertical direction, characterized in that in the vertical legs (6) of the guide piece (1) receiving window (7) for herein usable wear pieces (8) are arranged.

Description

The invention relates to a movable on a guide rail coal slicer whose guide claw is lockably connected to an exchangeable U-shaped guide piece in the longitudinal and vertical directions.

The generic coal slicer is made DE-20 2004 001 301 U1 discloses and discloses a guide piece, wherein the wear piece is an integral part of this component.

This leads to the disadvantage that under the high signs of wear in underground mining regularly the entire leader must be replaced. In addition, the guide piece is in frictional contact over its entire length with the guide rail of the planer. Especially in the transition region of a channel shot to this next angled gutter shot of the longwall conveyor arise unnecessary, the wear-increasing friction contacts. Frequent change of leaders, in difficult underground conditions, leads to costly material exchange and production stoppages.

The invention is therefore based on the object to bring wear-reducing guide pieces used, which are also easy to install and cheaper.

This object is achieved by means of the invention in that the actual guide piece reaches a longer service life by avoiding direct horizontal contact of this component with the guide strip.

The achievable by the solution of the above-described object advantages are that after releasing the longitudinal locking the guide piece is moved out of the guide claw and now no longer every time the entire guide piece but only the wear pieces must be replaced. Since the wear pieces are formed such that only the required support surface comes to rest on the guide rail, the frictional forces and thus the wear are significantly reduced here.

The inventive solution of the problem will now be explained with reference to two figurative representations.

1 shows an exploded view of the guide piece;

2 shows a side view of the guide piece.

On the presentation of the well-known Gleithobelführung, see dressed state of the art, can be omitted.

The exploded view after 1 shows a leader 1 that's at its stop page 2 a collar 3 having. The leader 1 is between the guide bar, not shown, and also not shown guide claw to the stop of the collar 3 pushed to the guide claw and secured in this position by locking both in the vertical direction and in the longitudinal direction of the pan. The safety in the longitudinal direction of the head is primarily by the collar 3 at the stop side 2 performed. To the loss of the leader 1 to prevent at opposite Hobellaufrichtung is at least one preferably as Vieraktriegel 4 designed fuse element provided. The Vierkantriegel 4 is driven through an opening adapted to the four-can-bolt in the guide claw. The vertical securing of the guide piece 1 is attached by two inside of the guide claw, preferably square supports 5 reached. The vertical thighs 6 of the guide piece 1 are with graduated recording windows 7 equipped, in the preferably symmetrical wear pieces 8th be used. The recording windows 7 are to the stop page 2 in the outside gradation 9 designed longer than on the front 10 , In the gradation 9 becomes a key element 11 for securing the wear piece 8th inserted, which is an externally projecting locking element 12 for vertical fixation of the guide piece 1 in the area of the stop side 2 having. In the gradation 13 , on the front 10 of the guide piece 1 , becomes a feather key element 14 for securing the wear piece 8th used. This feather key element 14 is in the installed state outside flush with the vertical leg 6 of the guide piece 1 , The securing of the key elements 11 and 14 each one of a recessed arranged Allen screw 15 guaranteed.
