Abstract:
The present invention relates to the laying of pipes, in particular concrete drainage pipes comprising a string of connected pipe sections. A pipe pushing tool (26) is provided, comprising a connection head (28) and a unitary elongate beam (30). The connection head (28) comprises a connection (56) for a quick hitch coupling, and a channel for receiving the beam (30). The beam (30) is slidable within the channel so that the vertical position of the beam relative to the connection head (28) can be adjusted. Selectively engageable locating features (46,48,50,52) are provided to support the beam (30) in a plurality of predefined vertical positions relative to the connection head (28). The invention also provides an invertible connection head (28) for a tool, then connection head (28) comprising a connection (56) for a first quick hitch coupling at a first side of the connection head (28) and a connection (58) for a second quick hitch at a second side of the connection head (28) opposite the first side.
Abstract:
A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.
Abstract:
An attachment is described that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break out (i.e. disconnection or disassembly) from another section of pipe and/or make up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint to a predetermined torque value, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.
Abstract:
The invention contemplates a working implement, for use with an excavating type machine, which semi-automatically brings a pipe section to a specified grade, slope, and line for emplacement in a line of pipe sections to be laid on the specified grade slope and line. The implement is rigidly mounted to the excavation machine whereby the position of the implement can be maintained within narrow tolerances while the pipe section is linearly inserted into a previously laid pipe section, and can be retained at the specified grade, slope, and line while fill material is emplaced and consolidated about and under the pipe, with sufficient density that the pipe can be released without the pipe moving outside normal tolerances of the specified grade, slope and line. In general, the invention contemplates the machine and implement automatically bringing the pipe section to such specified height or grade, thus bringing the pipe section into position and angular alignment with respect to the specified pipe line, automatically establishing and holding specified slope, and optionally cross-slope, of the pipe section. The pipe section is then linearly inserted into the previously laid pipe section by the operator manually activating the linear insertion actuator.
Abstract:
The invention relates to pipe clamps and is particularly concerned with equipment that combines ease of handling and transportation and which can ensure correct alignment of curved, polyethylene pipe ends (3,4) and their presentation to an appropriate coupling means. This objective is met by a construction comprising first and second clamp means (8,10), said first clamp means (8) being pivotally secured at or towards one end of an inflexible, extendible means (6) and said second clamp means (10) being pivotally secured at or towards the opposite end of said extendible means (6), the free ends of the clamp means being detachably and pivotally secured to each other.
Abstract:
Vorrichtung zum Zusammenziehen von Kanalrohren mit grossem Durchmesser, bestehend aus einer fahrbaren Zugeinrichtung mit einer daran angelenkten Abstützeinrichtung in der Form eines doppelarmigen, mit angelenkten Stützschuhen versehenen Hebels, dessen unterer Hebelarm um ein Vielfaches kleiner ist, als der obere Hebelarm und gegenüber diesem im stumpfen Winkel gegenüber dem zu ziehenden Rohrstück nach rückwärts abgewinkelt ist.
Abstract:
The present invention relates to the laying of drainage pipes, in particular concrete drainage pipes comprising a string of connected pipe sections. A pipe pushing tool (26,126) is provided to assist with jointing adjacent sections of pipe (2,12). The tool (26,126) is attachable to a quick hitch coupling, for example as on the arm of an excavator, and has a pair of adjustable beams (36,38,136,138) releasably secured to a main beam (34,134). Each adjustable beam (36,38,136,138) can be secured to the main beam in more than one position to thereby adjust the width of the tool (26,126).
Abstract:
A cold water pipe assembly, and mechanisms for generating a cold water pipe assembly, are provided. A plurality of mooring lines are secured to a pipe end member. A pipe segment of a plurality of pipe segments is slidably coupled with respect to the mooring lines at a plurality of locations on a pipe wall of the pipe segment. The plurality of pipe segments is iteratively extended to form a pipe assembly of a desired length by joining a next pipe segment to a previous pipe segment to extend the pipe assembly, and lowering the pipe end member and the pipe assembly by extending the mooring lines. At least some of the next pipe segments are slidably coupled with respect to the mooring lines at a plurality of locations on a respective pipe wall of the at least some of the next pipe segments.
