Abstract
A method and apparatus for transporting a pipeline pig provides a housing having an interior. A jacking mechanism is contained within the housing interior. A carriage is supported by the jacking mechanism for movement between an upper extended and a lower retracted position. The carriage has a concave surface that generally cradles a pipeline pig to be transported. A pulling device on the housing enables a pipeline pig to be pulled from a location that is not on the carriage to a position that is on the carriage. The position that is not on the carriage can be for example a pig trap. As part of the method of the present invention, the pulling device pulls the pig from the pig trap or other location to the carriage and then the carriage is retracted into the housing for transport to a remote location.

- 1. Field of the Invention
- The present invention relates to pipeline pigs and more particularly to a method and apparatus for transporting pipeline pigs, such as after they have been used to clean or scrape a section of pipeline. More particularly, the present invention relates to an improved pipeline pig transport method and apparatus that employs a housing having a specially shaped carriage that can be moved with a jack or jacking mechanism or elevator between collapsed and extended positions, the housing enabling transport of the contaminated pig after it has been removed and is covered with contaminants such as wax, oil, debris, dirt or the like.
- 2. General Background of the Invention
- Pipeline pigs are often employed to clean a section of pipeline. A discussion of pipeline pigs can be found at www.ppsa-online com/about-pigs.php.
- Pig traps are used for inserting pigs into or removing pigs from a pipeline. The pig trap can be used for launching a pig or for removing a pig and without interruption of flow.
- One of the inventor's customers invited him to look at a very crude device that was being used to assist the customer with pulling out pigs from pipelines that basically could only roll to the door of the pipe and then back away so the workers could close the door. This unit's feature was basically a trough with a hand winch which the operator cranked to pull the pig out. The liquids fell below in a container that was built in or part of the unit. After water was drained in the trough on site or overboard and liquids or oil were pumped out for proper disposal. The surface of the unit was basically grating that was bent to a concaved fashion to receive the pig. This unit was not portable for highway transport and also had no lid for protection of the pig nor did it have wind guards to prevent oils or residue from going into the environment. This unit did not retract the pig within itself and also was felt to be of great possible injury to the operator when removing the pig by cranking (as there was a risk of cable failure, which could injure the operator).
