Embodiment Construction

[0047] [0033] Referring to the drawings, in which like numerals refer to like features, a non-limiting example of a transport device according to the invention is indicated by the reference numeral 10.

[0048] [0034] The transport device 10 adapted to move along a surface, in particular along an ore draw shaft, comprises two outer gripping members 30, one of which remains fixed relative to the other; and an inner gripping member 40, It is located between the two outer clamping parts 30 and is movable relative to the outer clamping parts 30 . The two external clamping parts 30 are connected to each other by an elongated connection mechanism 34 in the form of a tube, rigid rod or shaft. The inner clamping member 40 is located on a bushing 44 slidably mounted on the connecting mechanism 34 for sliding movement of the inner clamping member 40 relative to the two outer clamping members 30 .

[0049][0035] Each clamping member 30 or 40 is movable between a circumferentially expand...

Abstract

The invention provides a conveyance device (10), suitable for traveling along a surface and conveying an explosive charge, the conveyance device includes a propulsion member (20, 22) having two opposite ends (24), the propulsion member is displaceable between a longitudinally extended position wherein the ends are displaced away from one another; and a longitudinally contracted position wherein the ends are displaced towards one another; an outer gripping member (30) and an inner gripping member (40), each gripping member is displaceable between a circumferentially expanded position wherein an outer perimeter of the gripping member is displaced away from a center of the member so as to, in use, abut at least part of the surface; and a circumferentially contracted position wherein an outer perimeter of the gripping member (30, 40) is displaced towards the center of the member so as to be spaced apart from the surface; the propulsion member (20, 22) and the gripping members is configured in order for sequential displacement of the propulsion member and gripping members to result in peristaltic displacement of the conveyance device(10) relative to the surface.

Description

technical field [0001] [0001] The present invention relates to a transport device and more particularly, but not exclusively, to a peristaltic transport device suitable for transporting an explosive charge while moving within an elongated channel. Background technique [0002] [0002] It is often desirable to pass conveyance objects in or along an elongated passageway that is not suitable for human entry due to size constraints or safety concerns. This situation occurs, for example, in mining environments when ore chutes are blocked. [0003] [0003] The ore-drawing chute is a passage drilled between the parallel upper tunnel and the lower tunnel in the mine. The ore in use is piled up at the upper end of the ore-drawing chute, which extends downward from the bottom wall of the upper tunnel. The lower end of the ore chute extending upwardly from the top wall of the bottom tunnel is closed by means of a steel door, thus allowing ore to accumulate inside the ore chute. When r...
