Abstract
A guide for mineral mining machines is composed of assemblies each secured to the mineral face side of a conveyor. The assemblies have angle plates secured to the side walls and structures formed with spacers separating upper and lower passages for a drive chain. Covers are detachably and pivotably mounted to the structures. The covers can be secured in a closed position covering the upper passage or swung outwardly to an open position on push-in hinge joints formed at their lower regions by interengaging components of the covers and the structures. The hinge joints have complementary projections and recesses which interengage when the covers are closed.
Claims15
In a guide for mineral mining;
- said guide comprising means defining upper and lower passages along which a drive chain is to be circulated, said defining means including spacers separating the upper and lower passages, and covers which close off the upper passage and which are pivotable outwardly from the upper passage to an open position;
- the improvement comprising push-in pivot joints provided for the covers which permit the covers to be pivoted between the closed and open positions and to be detached by lifting, and co-operating projection means and recess means for interengaging when the covers adopt the closed position to prevent detachment of the covers by lifting, and to become disengaged as the covers are pivoted to the open position to permit the covers to be detached by lifting.
A guide assembly for attachment to a side wall of a conveyor to form part of a mineral winning machine guide;
- said guide assembly comprising an angle plate with an upstanding portion for fixing to the side wall and a lower portion for supporting the machine, a structure fixed to the upstanding portion of the angle plate and including spacers which serve to separate an upper and lower chain guide passages disposed alongside the upstanding portion of the angle plate and at least one cover pivotably mounted to said structure and serving to close off the upper chain guide passage, said cover being movable away from the upstanding portion of the angle plate to an open position permitting access to the upper chain guide passage;
- wherein co-operating components on the cover and the structure provide push-in hinge joints which permit the cover to be pivoted between the closed and open positions and to be detached by lifting, and mating projection means and recess means for locking together only when the cover is in the closed position to prevent the cover from being detached by lifting.
