摘要： Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters. The tool can be used manually or in an automated fashion to push and pull the paint gun and paint the interior of a pipe.

摘要： A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, adjacent chambers being fluidly connected, and a fluid source attached to one end of the set, such that the chambers inflate sequentially. The chambers are constructed of an elastic material and have a wall thickness and dimensions such that they have a characteristic with a non-monotonous relationship between the inflation pressure within the chamber and the chamber's inflated size. The characteristic is such that after an initial inflation pressure peak, the non-monotonous relationship adopts a negative slope, such that the volume of the chamber increases more rapidly than the volume of fluid flowing into it, and the inflation pressure of the chamber falls. This effect causes the chamber to inflate and anchor rapidly, while essentially slowing down the inflation of the succeeding chamber until inflation of the first is complete.

摘要： A pipe splitter is shown including a splitter body having a central opening configured to accept a pulling or pushing member. An expander has an entry profile smaller than an inner diameter of a pipe to be split and an expanded profile that is larger than the inner diameter of the pipe to be split. A protrusion is disposed on the expander. The protrusion is configured to concentrate splitting stress at a location on the pipe. The concentrated splitting stress is greater than a threshold stress of the pipe to burst the pipe. In some examples, a method of pipe splitting is described.

摘要： A rod pushing and pulling machine includes at least one hydraulic cylinder having a front end thereof engagable with a reaction surface at an entry opening of an existing pipeline or borehole, a spindle assembly, and a dual vise assembly. The spindle assembly includes a frame, a spindle shaft rotatably mounted in the frame, a distal end of the spindle shaft being threaded for engagement with a mating thread of a rod, a drive system for rotating the spindle shaft in threading and unthreading directions, the spindle frame being secured to a rear end of the hydraulic cylinder for pushing or pulling of a rod string engaged to the spindle shaft upon extension or retraction of the hydraulic cylinder, and a support assembly for the spindle shaft. The support assembly includes a set of roller bearings rotatably supporting the spindle shaft, a radial flange on the spindle shaft, and a load flange secured to the spindle frame positioned to engage the radial flange, whereby the radial flange comes into engagement with the load flange during pulling operation to prevent rotation of the spindle shaft during pulling operation, and leaves engagement with the load flange during pushing operation so that the spindle shaft may rotate during pushing operation supported by the roller bearings. The dual vise assembly has two pairs of separately actuable jaws positioned to grip a rod nearest the spindle shaft and a rod adjacent the rod nearest the spindle shaft.

摘要： A mount for traveling within a pipe to center a tool, such as a camera, within the pipe. Inner and outer concentric cylinders are slidably nested. Pivoted leg pairs have one end connected to the outer cylinder and another end connected to the inner cylinder. The pivoted leg pairs move radially inward or outward as the inner and outer cylinder move axially with respect to each other. A spring biases wheels attached to the distal end of the pivoted leg pairs radially outward. The mount centers the inner and outer cylinder within the pipe and automatically adjusts to different diameters of pipes. The mount overcomes obstructions within the pipe and is easily retrievable. The interior of the pipe may be inspected or worked upon.

摘要： A puller is provided with a number of advantages. Pullers are described that have a high power to weight ratio, and a high power to volume ratio. Examples of pullers and pulling systems include harmonic drive gear reduction elements and configurations that provide high cable friction in a small device volume. Examples of pullers and pulling systems also include constant force pulling which is desirable in particular for small diameter pipe replacement. Using pullers and pulling systems as described, minimally invasive pipe replacement operations are possible. Reversible pullers are also provided that decrease the amount of time needed to burst or split multiple segments of pipe.

摘要： An in-pipe apparatus for pipe inspection or maintenance is provided. The apparatus includes: a rotational deployment mechanism to rotationally deploy a probe or tool about an inner circumference of a pipe with respect to an axis of rotation; a radial deployment mechanism to radially deploy the probe or tool in a radial direction from the axis of rotation toward a target point on the inner circumference; and a passive centering mechanism to passively align the axis of rotation with the axis of the pipe. In some embodiments, the rotational deployment mechanism includes a motor to rotate the radial deployment mechanism about the axis of rotation. In some embodiments, the apparatus further includes a longitudinal deployment mechanism to longitudinally deploy the probe or tool along the pipe axis, with the passive centering mechanism passively maintaining alignment of the axis of rotation with the pipe axis during the longitudinal deployment.

摘要： A pipeline profiler includes an elongated body and a plurality of mechanical arms projecting radially about the elongated body. Each mechanical arm has an adjustable angle bracket shape and a hinge joint formed at a corner of the adjustable angle bracket shape. Odometers to measure a travel distance of the elongated body are coupled to the mechanical arms at the hinge joints of the mechanical arms. Motion devices are coupled to the elongated body to detect the azimuth and inclination of the elongated body. To obtain a profile of a pipeline, the pipeline profiler is attached to a pig that is movable through the pipeline by a fluid pressure in the pipeline.

摘要： The present invention discloses a pig with improvement in the suspension and centralization system, allowing it to behave properly in any diameter within a design range. The seals in the shape of petals and overlapping discs, responsible for the pressure differential that causes displacement of the pig inside the pipe, were designed to close gradually when necessary, until reaching the minimum internal diameter of the pipe. In this configuration, the face of the seals normally generates a lot of friction with the inner wall of the pipe, making it difficult to move. Metal wafers (11) were developed and applied to the seals to reduce friction. A coupling element (4) was also developed to interconnect the different modules of the pig allowing wide movement of the pig inside the pipe, facilitating its passage by sharp curves and inside the equipment. The pig has petal and disk type seals, mechanical centralization and cleaning module (5) and interconnecting tubes (4).

摘要： A cleaning pig assembly is provided for use on a tubular drag conveyor. The assembly is quickly and easily mounted anywhere along the cable, chain, or rope via slots in the assembly components. The components include a puck, a plate, a drag disc, and a cleaning member or tool sandwiched between the puck and the plate. The drag disc provides interference fit on the cable, chain, or rope holding the assembly on the cable, chain, or rope and prevents sliding of the assembly along the cable, chain, or rope during use. The cleaning assembly is installed without the use of tools or clamps. Multiple interchangeable cleaning members are provided depending on cleaning needs.
