摘要:
An in-pipe work device comprising at least two movement mechanisms (20a, 20b) connected with each other in a longitudinal direction of a pipe (11) by a flexible tube (15), and a control device (19) for controlling the movement mechanisms (20a, 20b), the movement mechanisms (20a, 20b) including a body (21) connected to the flexible tube (15), a guide member (22) installed on the body (21) such that the guide member (22) is slidable in an axial direction, a support leg drive mechanism (24) provided on the guide member (22) and having a support leg (23) movable in a radial direction of the pipe (11), for pressing the support leg (23) against an inner wall of the pipe (11), thereby to hold the guide member (22) kept unmovable in an axis direction of the pipe (11), a slide mechanism (25) for relatively sliding the guide member (22) and the body (21), with the support leg (23) pressed against the inner wall of the pipe (11), thereby to slide the body (21) in the axis direction of the pipe (11), wherein the control device (19) controls the in-pipe movement device so as to move in a pipe (11) by itself, by sequentially operating the plurality of movement mechanism (20a, 20b) in a predetermined order.
摘要:
A robotic unit (10) for coupling to an internal buckle arresting pipeline isolation tool (120) that is suitable for use in a pipeline that is being laid from a reeled pipeline vessel. The robotic unit having the ability to position the isolation tool either above or below the SAG bend or touchdown point of the pipeline. The robotic unit (10) has first and second ends which are separable from each other and a hydraulic system having a plurality of pipeline engaging means (140, 150) positioned along an exterior surface of the robotic unit. The hydraulic system of the robotic unit being operable to returnably separate the first and second end of the robotic unit and to engage the pipeline engaging means (140, 150) with the interior surface of the pipeline. The robotic unit (10) further comprising a control unit in communication with the hydraulic system to control the movement such that the robotic unit propels the isolation tool along the inside of a pipeline.
摘要:
L'invention concerne un robot destiné à déplacer un colis dans une conduite d'enfouissement, ce robot comprenant une partie avant (4) et une partie arrière (5) reliées l'une à l'autre par un actionneur central apte à rapprocher et à éloigner ces parties l'une de l'autre, la partie avant (4) et la partie arrière (5) ayant chacune un contour circulaire pourvu d'un vérin torique (10, 11), tel qu'un joint torique gonflable, chaque partie pouvant être bloquée dans la conduite par gonflage de son vérin torique (10, 11), ce robot comprenant une unité hydraulique (29) apte à gonfler et à dégonfler le vérin torique avant (10) et le vérin torique arrière (11) avec un liquide, et une unité de commande de l'unité hydraulique (29) et de l'actionneur central.
摘要:
The invention relates to a pipe robot with at least one first (1) and one second (2) balloon-shaped expansion element which can be independently expanded and released. Said robot further comprises at least one connecting element (3) which is arranged between said expansion elements (1, 2) and is connected to them. Said connecting element acts in the axial direction and can be adjusted in length by pressurization.
