Abstract
1292076 Mining machine COAL INDUSTRY (PATENTS) Ltd 11 May 1971 [15 May 1970] 23727/70 Heading E1F An underframe for a mining machine comprises a support component for the machine, roller mounting means secured to the component and four pairs of rollers rotatable about a horizontal axis and mounted for rolling along a track extending along a path of the machine. The underframe may comprise, Fig. 3, a support platform 24 secured to two bridge members 28, one at either end of the platform. Each bridge member carries a pair of rollers 26, rotatable about a horizontal axis, on the face and goaf side of the underframe, a roller 32 rotatable about an inclined axis, and two rollers 36 rotatable about a vertical axis. When the underframe is mounted on conveyor 4, rollers 26, 32, 36 roll on tracks 20, 30, 34 and 38 respectively. Alternatively the underframe comprises Fig. 7, a platform 48 carrying at each of its four corners a frame 56 carrying a pair of rollers 54 rotatable about a horizontal axis. Each face-side frame also carries two rollers 60 rotatable about a vertical axis. When the underframe is conveyor-mounted, rollers 60 roll on the sides 62 of trough-shaped track 52, the upper ends of rollers 60 abutting plates 64 of track 52. The underframe may comprise only one roller rotatable about a vertical or an inclined axis, and a track-engaging fail-safe brake biased by a spring to a braking position.
