Abstract:
A self-contained, on-board diagnostic system integrated with a control system (195) and method of using the same. Various control system coefficients and parameter settings may be set and edited with the on-board system, without the use of external hardware. In certain embodiments, an operator panel display (99) may be used as a display for the on-board system. A menu navigation scheme can be employed to access a plurality of screens in an organized, efficient manner. The on-board system can be adapted for use with a tracked trencher (40) and/or other mobile equipment.
Abstract:
A guidance control system is configured to control the positioning and spatial orientation of a digging implement (22) mounted on a frame of a trenching machine (10) for working a subsurface of earth to a desired trench profile (28). The position of a dynamic cutting edge (32) of the digging implement is monitored and then controlled so that the sensed dynamic cutting edge position is equal substantially to the calculated dynamic cutting edge position. The guidance control system includes sensors (34), a processor (35), and accessible memory providing digital design information regarding the desired trench profile.
Abstract:
Trenching apparatus comprises a cutting device (23), preferably an endless chain cutter, mounted on a prime mover (21) for positioning the cutting device in a trench (18) with the prime mover movable on the ground surface (22) above the level of the trench. Where the cutting device is a chain cutter, the boom projects forwardly and downwardly relative to the direction of cutting the trench, and drive means are arranged to drive the chain in a direction to carry the cutting elements upwardly around the distal end ofthe boom and rearwardly along the upper run (30) of the endless chain cutter (23). In operation the distal end of the chain cutter (23) is positioned against the end face of the trench at the bottom of the trench (18); the prime mover (21) moves the chain cutter forwardly in the trench while operating the chain cutter, so as to produce an undercut (55) in the end face (54) of the trench; and the lifting means (25) lifts the cutting device (23) upwardly from the undercut through the material of the end face so as to cut material from the end face of the trench.
Abstract:
A submarine plough comprises a plough share for cutting a trench in the sea floor, an inlet for receiving an elongate flexible member such as a cable, and an outlet provided rearwardly of the plough share for inserting the flexible member into the trench. A guide means in the form of a displaceable bell mouth device (130) has a working position in which at least one guide surface is arranged adjacent to the outlet to enable the flexible member from the outlet to pass over the working surface. The or each guide surface has a sufficiently large radius of curvature to minimise damage to the cable (2). A displacement means such as a hydraulic cylinder (136) is provided for displacing the bell mouth device (130) out of its working position.
Abstract:
Disclosed is a machine for uncovering a pipeline, comprising a crawler-mounted underframe (1), on which is mounted working machinery (2) including a frame (3) with a device (4) for clearing away earth, and an operating element (5), as well as power drives in the form of hydraulic cylinders (15, 17) used to pivot and immobilize the frame (3) on a vertical and horizontal plane. The operating element (5) comprises a chain portion (19) which rotates around the axis of a drive shaft (21) by means of a power drive in the form of hydraulic cylinders (22). The distance between the portions (19) can be adapted to the diameter of the pipeline (7). The contour follower (6) comprises an arm (26), preferably attached to the operating element (5), as well as a power drive in the form of a hydraulic cylinder (38) for pivoting and immobilizing the arm (26) on a vertical plane; the end of this arm is fitted with a support for the pipe (7) with the ability to rotate on two planes, in the form of a sliding block (27). The machine has a device to control the position of the working machinery (2) with respect to the pipe (7), said device preferably comprising a computer (94) with sensors (96, 97, 98, 123) to measure the angles of rotation of the working machinery (2). The hydraulic cylinders (15, 17, 22, 38) are used to move the working machinery into and out of the trench, and to fold it into a compact position for transportation. During maneuvering, the machine is moved across the pipeline and rotated with a back and forth movement of its center of turn.
Abstract:
An apparatus (2) for forming a trench in a sea floor and/or displacing material on the sea floor is disclosed. The apparatus comprises a body (4 ) and front skids (12) mounted to the body for engaging the sea floor and supporting the body. The front skids are adjustable between a first mode, in which the front skids engage the sea floor, and a second mode, in which the front skids engage the sea floor adjacent the trench and at the trench walls.
