The Structure of Drill Pipe Loading and Unloading in Horizontal Directional Drilling Rig
Sep 04, 2023| The mud system of the horizontal directional drilling rig is composed of a truck-mounted mud system and a mud mixing system; the mud mixing system is used for mud mixing, mixing, and providing mud to the truck-mounted mud system, and the truck-mounted mud system drives mud drill pipes and bits into the hole , to stabilize the hole wall, reduce the rotary torque, pull pipe resistance, and cool the drill bit. Launch the probe to remove the soil debris generated by drilling, etc.
The mechanism of horizontal directional drilling rig adopts flexible feeding device, which has high coordination. It is necessary to carry out logical control on functions such as the lifting of the drill pipe, the expansion and contraction of the shuttle arm, the position of the power head, and the detection of the completion of loading and unloading, so as to realize the self-use advanced control between multiple actions.
At present, the drilling rod loading and unloading mechanism of the horizontal directional drilling rig: the mechanism is generally composed of the drilling rod, the drilling rod box, the lifting and lowering of the drilling rod, the shuttle arm that can be extended and retracted, and the automatic selection device for the number of drill rod rows. There are differences in the access and transportation of drill pipes from various manufacturers at home and abroad. Some use manual access to drill pipes. Manual loading and unloading of drill pipes is not only inefficient but also increases the labor intensity of operators; The retraction force of the spring is used as the clamping force for the access of the rod mechanism. Accidents such as drill pipe falling off often occur, and the work is unreliable. The rotary knot can load and unload the drill pipe more conveniently, reduce the labor intensity of the operator and improve the work efficiency.
