Background
PLS system: pipeLaydown System, a system that uses more horizontal/vertical switching systems on an automated drilling platform, has the main functions of performing horizontal/vertical switching of drill pipes and assisting the vertical drill pipe operating system in performing offline single root operations.
And (3) root-restoring: the two drill rods are connected together to be called a multi-root.
And (3) standing: the three drill rods are joined together as a stand.
In the prior art, drilling platforms or land drills often employ automated or semi-automated racking systems.
For example, automatic racking systems commonly used in drilling platforms typically include: catwalk machine, PLS system, mousehole, iron roughneck, calandria machine, etc. The operation flow is as follows: the catwalk machine conveys the drill rod to a set position; the PLS system grabs the drill rod, converts the drill rod to a vertical position and places the drill rod into a rat hole; the PLS system transmits the drill rod to a pipe arranging machine, and the drill rod is lowered to a set position and buckled by an iron driller; the calandria machine extracts the connected multi-root rat holes; the PLS system puts the drill rod into the rat hole; the calandria machine lowers the compound roots to a set position, and the compound roots are buckled by an iron driller; the calandria machine puts the connected stands into the rat hole and puts the rat hole into the discharge rack.
