Problems solved by technology

[0004] Despite the use of a centering screw with a reduced diameter shank portion and a shoulder nut with a large area in this type of plow guide, it is still possible to loosen the screw connection holding the cover housing in the closed position, which On the one hand, it causes large vibrations and vertical forces, and on the other hand, it causes forces acting on the root area of ​​the housing which is used as a swivel hinge when the plow body and the plow chain are running

Embodiment Construction

[0015] As is known, the plow sliding guide shuttle, generally designated 1 in FIG. 1 , is mounted on the mining face side on a side profile 2 of a chute section 3 of a chain scraper conveyor, not shown in detail. The chute section 3 and the plow sliding guide shuttle 1 that can be used for greatly restricted hinged movement and mutual tension connection constitute the plow guide device laid in the mining face. The plow, whose arm is connected to the traction strand 4 of the plow chain, moves along the guide.

[0016] Each guide shuttle 1 of the plow guide consists of a gusset 5 with a base arm 7 slightly inclined to the base and supported on the base and an essentially vertical, that is to say parallel to the excavation face The towering arm 8 of the guide shuttle 1 and the substantially entire length of the chute section 3 welded on the arm 8 extend. Bottom arm 7 constitutes with its upper side 7' a lower rail for a plow body not shown and together with a firm guide beam 10 ...

Abstract

A plough guide for underground mining ploughs, with angle plates (5), whose extended arm (8) is fastened on the working face side to the conveyor pan (3) of a chain scraper conveyor and whose base arm (7) towards the face, supported on the ground (6), forms a sliding track for the plough, with upper and lower chain channel slides (11, 12) for the plough chains separated by distance pieces (9) fastened preferably at a distance from each other on extended arms of the angle plates, with a cover (15) closing the chain channels (12, 11) to the working face side and which can be pivoted towards the face, having at least one abutment part (21), which can be fixed on the plough guide and released, and with a guide rail (18) arranged on the plough guide at a distance from the sliding plough track. The abutment part (21) of the cover (15) is clamped between the angle plate (5) and a securing part (30) at a distance from the cover (15) screwed onto the angle plate (5).

Description

technical field [0001] The invention relates to a plow guide for coal plows used in underground operations, having a corner plate whose upstanding arms are fixed on the chute section of a chain-type scraper conveyor on the side of the digging face and directed towards the digging The upper arm supported on the bottom plate constitutes a plow slide rail; there are also upper and The lower chain channel; has a cover plate that closes the chain channel to the mining face and can be turned in the direction of the mining face, it has at least one stop that is detachably fixed on the plow guide; and has a planer The coal machine slide rail is set on the guide bar on the coal plow guide device at a certain distance. Background technique [0002] It is well known that the plow guide device consists of a single guide shuttle, which is mounted on the chute section forming the conveyor trough of the chain scraper conveyor on one side of the mining face and forms a guide for moving alo...
