Benefits of technology

"The invention is about a type of mining machine that has a roof bolt drilling and setting apparatus integrated into it. The machine is designed to offer stable operating platforms while also protecting the operator from injury. The platforms are pivotable and displaceable, allowing them to be pressed against the side wall of the machine. The machine can be appropriately centered within the road during displacement, especially with sloping roads. The platform parts are connected to the machine frame, and the geometry of the connection allows for smooth pivoting. The platforms can also be used as collision protectors and to center the machine in the event of oblique floors. Overall, the invention provides a stable and safe mining machine with enhanced protection for the operator."

Problems solved by technology

Such an impediment of the curve-going ability may result from accordingly largely dimensioned operating platforms provided for additional devices such as roof bolt drilling and setting apparatus.

Embodiment Construction

[0018]FIG. 1 depicts an advance working machine 1 on whose front end facing the work surface a cutting cylinder 3 is arranged to be pivotable in the vertical direction. The advance working machine 1 comprises lateral operating platforms 4 and pivotally hinged platforms 5 accordingly enlarging the operating range in the vicinity of roof bolt drilling and setting apparatus schematically indicated by 6. The lateral partial region of the pivotable platform 5, which is adjustable at the side wall, carries runners 7 and a shield-like protection wall 8 telescopically designed in the vertical direction by means of extractable parts 9 so as to likewise ensure a lateral protection against collapsing rock in the region of the operating platform 5.

[0019] On the rear end of the advance working machine 1, appropriate bearing sites for a conveying means are to be seen on the machine frame 10.

[0020] In the illustration according to FIG. 2, the operating platforms 5 are in a laterally pivoted-out ...

Abstract

In an advance working or mining machine including a traveling mechanism, excavation tools movable over the mine face as well as roof bolt drilling and setting apparatus having associated operating platforms for the operation of the roof bolt drilling and setting apparatus, at least a part of laterally cantilevering platforms is each arranged to be pivotable and / or displaceable transversely to the longitudinal axis of the machine.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an advance working or mining machine including a traveling mechanism, excavation tools movable over the mine face as well as roof bolt drilling and setting apparatus having associated operating platforms for the operation of said roof bolt drilling and setting apparatus. [0003] 2. Prior Art [0004] When driving roadways, or reclaiming material below ground, different mining machines are employed. Advance working machines or mining machines having their own traveling mechanisms, which are usually designed as crawler mechanisms, as a rule, comprise excavation tools that are movable over the mine face, whereby walling is to be preferably realized as closely to the mine face as possible in order to ensure maximum safety during excavation or advance working. Apart from using separate vehicles for walling, which transport roof bolt drilling and setting apparatus as well as the structural elements r...
