Definitions

  • An extensible boom particularly for mounting on a mobile rock breaking or mining machine, comprises [211 App! 272954 an extensible member mounted for rotation about an axis extending in the direction of its length, a non- [30] F i A li i P i i D rotatable extensible member operative to impart ex- Aug. 4, 1971 Great Britain 36622/71 tension to said rotatable member of the boom means for extending the non-rotatable extensible member of 52 us. c1 173/43, 248/16 the and means said matahle member the 51 Int. Cl.
  • One particular application of the invention is to a boom for carrying and applying a rock breaking tool to a rock or other mineral face for the excavation or breaking down thereof.
  • an extensible boom in which one extensible member of the boom is also adapted for rotation about an axis extending in the direction of its length and another and non-rotatable extensible member of the boom imparts such extension to said rotatable member of the boom, means being provided for extending the non-rotatable extensible member of the boom, said rotatable member providing a mounting for a tool which operates on an axis which is different to said axis of the rotatable member and is movable relatively thereto.
  • the boom comprises a fixed or stationary outer member, a rotatable inner extensible member, a non-rotatable, slideable intermediate extensible member, means for effecting sliding movement of said intermediate member and interengaging or connecting means between the intermediate member and the rotatable inner member whereby they are together extended and retracted.
  • rotation of the extensible inner member is effected through a splined drive shaft rotatably mounted on the stationary outer member and on which the inner member is slideable.
  • FIG. 1 is a diagrammatic longitudinal sectional view of a boom
  • FIG. 2 is a more detailed longitudinal elevation of the boom with the upper half in section
  • FIG. 3 is a cross-sectional view of the rotary driving mechanism of the boom shown in FIG. 2,
  • FIG. 4 is a side elevation of a mobile rock breaking or mining machine fitted with a boom as shown in FIGS. 1, 2 and 3,
  • FIG. 5 is a rear elevation of the machine shown in FIG. 4, and
  • FIG. 6 is a plan view of the machine shown in FIG. 4.
  • the boom shown in FIG. 1 comprises a stationary outer cylindrical casing 10, an intermediate hollow cylindrical member 11 slideable in the casing 10, and an inner hollow cylindrical member 12 slideable and rotatable in the intermediate member 11.
  • the intermediate member 11 is held against rotation in the casing by a key 13.
  • Rotation of the inner member 12 is effected by hydraulic motor 14, mounted on the casing 10, which, through worm and worm-wheel gearing 15 and 16, drives a splined shaft 17 on which the inner member 12 is slidably mounted and to which it is keyed for rotation as indicated at 18.
  • the worm and worm-wheel gearing is housed in an enlargement 10a of the outer casing 10.
  • the worm and worm-wheel gearing has the advantage that the inner member 12 is automatically locked against rotation except when the motor 14 is operating because the worm-wheel cannot drive the worm.
  • crank and connecting rod arrangement may be used.
  • a double-acting hydraulic ram 19 is connected between a lug 20 on the stationary member 10 and a lug 21 on the intermediate member.
  • Interengaging abutments 22 and 23 are provided between the inner and intermediate members at the rear ends thereof and interengaging abutments 24 and 25 are provided between said members at the forward ends thereof.
  • the intermediate member 11 When the intermediate member 11 is extended, by extending the ram 19, the abutments 22 and 23 cause the inner rotatable member 12 to be extended. By operating the motor 14 the inner member 12 can be rotated.
  • the extending means for the boom may be external of the fixed member 10 or internal and there may be more than one such extending means.
  • the ram 19 can be used as a hydraulic lock to hold the boom against extension or retraction, the control valve means for the ram being adapted for that purpose.
  • the hydraulic motor 14 can be adapted to operate as a hydraulic lock to hold the member 12 against rotation.
  • FIGS. 2 and 3 The boom shown in greater detail in FIGS. 2 and 3 is basically of the same construction as that above described with reference to FIG. 1 and like reference numerals have been used to designate like parts.
  • FIGS. 4, 5 and 6 The mining machine shown in FIGS. 4, 5 and 6 is similar in construction, with the exception of the boom, to the machine described in the Specification of our patent Application Ser. No. 198,365.
  • the machine comprises a walking carriage 27 on which is mounted a chassis 28 and a turntable 29.
  • the turntable 29 supports, for angular movement about a vertical axis 30, bearing brackets 31 which support, for angular movement about a horizontal axis 32, a bearing bracket 33 formed on the enlargement 10a of the outer cylindrical casing 10 of the boom.
  • the boom is supported on the chassis so that it can be angled both laterally and vertically.
  • Said lateral angular movement of the boom is effected by a hydraulic ram 34 and the vertical angular movement of the boom is effected by a hydraulic ram 35.
  • the rock breaking equipment 26 comprises a boom extension 36 secured to the forward end 12a of the rotatable extensible member 12, said extension having pivotally mounted on its forward end, for adjustment about an axis 37, a tiltable turntable 38. Adjustment of the table 38 about the axis 37 is effected by a hydraulic ram 39 and about an axis 37a by a further ram, not shown.
  • a pressure-fluid operated rock breaking tool 40 which actuates a chisel 26a, is mounted on the table 38 and may be adjustable therealong. This pressurefluid operated rock breaking tool may be constructed as described in the Specification of our Application for Patent Ser. No. 218,671.
  • the table 38 provides a mounting, on the rotatable member 12 of the boom, for a tool which operates on the axis I-I which is different from the axis II-II of the rotatable member 12 and is movable relatively to the said axis IIII. More particularly, the axis II can be rotated around the axis II-Il of the boom, by rotating the member 12 by the motor 14, and also the axis l-l can be tilted about the pivot 37 relative to the axis ll-II.
  • An extensible boom comprising a fixed or stationary outer member, a non-rotatable intermediate extensible member slidably mounted in said outer member, an inner extensible member mounted in said intermediate member for rotation about an axis extending in the direction of its length, means for effecting sliding movement of said intermediate member, interengaging means between the intermediate member and the rotatable inner member whereby they are together extended and retracted, and means on said rotatable member of the boom for mounting a tool thereon so that said tool operates on an axis which is different to said axis of the rotatable member of the boom and is movable relative thereto.
