Title:
MACHINE FOR DIGGING UNDER PIPES AND CATERPILLAR TRACTION DEVICE
Document Type and Number:
WIPO Patent Application WO/1998/015165
Kind Code:
A2
Abstract:
The present invention relates to mining industry and mining works. The inventinve machine for digging under pipes, wherein said machine comprises a frame (1) having a caterpillar drive traction device (3) mounted thereon as well as left (4) and right (5) identical working organs. The working organs (4, 5) are each made in the shape of a mount (6) which is attached to the frame (1) and capable of forced rotation about the vertical axis (7). These organs also comprise a cylindrical endless-screw-type driving cutter (8) as well as a cylindrical blade (10) attached to the mount (6) coaxially behind the cutter (8). The cutter (8) is mounted at the lower end and on the side of the mount (6) so that its rotation axis is horizontal. The machine further includes a transversal stabilisation device (98) comprising two stabilisation mechanisms (99), wherein each mechanism comprises an adjustable-height support member (100) that rests on the bottom of the trench. The traction device (3) includes a frame (78) as well as a caterpillar that comprises rigid brackets (83) and flexible support members (84). The brackets (83) extend outwardly from the external surface of the caterpillar central part. The flexible support members (84) are connected to the brackets (83) so as to be incapable of linear displacement and are made short enough so as to stretch about the profile of the pipe cross-section. This invention may be used to increase the yield of machines as well as their reliability and durability.
