Powered Rat Hole Device

Abstract

The invention relates to a power rathole device, which belongs to the technical field of oil drilling equipment application. The present invention comprises a first guide mechanism and a second guide mechanism; the first guide mechanism is used to be installed on a drill floor having a first U-shaped opening, a centralizing device is installed on the first guiding mechanism, and the centralizing device Slidingly fit with the first guiding mechanism; the second guiding mechanism is located below the first guiding mechanism, and the second guiding mechanism is used to be installed on the derrick base, and a lifting mechanism is installed on the second guiding mechanism, and the lifting mechanism is located Right below the centering device, and the lifting mechanism is slidingly matched with the second guide mechanism, and the lifting mechanism moves synchronously with the centering device. Through the invention, the drill rod can be moved in the horizontal direction on the drill floor, thereby solving the problem that the drill rod can only enter and exit the mouse hole by moving up and down.

Description

technical field [0001] The invention relates to a power rathole device, which belongs to the technical field of oil drilling equipment application. Background technique [0002] The power mouse hole is an automatic pipe processing equipment on the oil drilling rig, and cooperates with other equipment to complete the operation of offline erection or offline erection, so as to realize the transportation, discharge and storage of drill pipes between the drill floor and the ground. At present, the main body of the existing power rathole is a cylindrical tube, and the drill pipe can only enter and exit the rathole through up and down displacement, so that when the power rathole is connected to the vertical root off-line, the drill pipe on the ground must first be transported to the drill floor. The derrick base is set under the drill floor, and then the equipment puts the drill pipe in the rat hole, and then the drill pipe is erected in the rat hole. Take it out and put it in th...

AI Technical Summary

Problems solved by technology

At present, through the method of connecting vertical roots or unloading vertical roots offline through power ratholes, the drill pipe can only enter and exit the rathole by moving up and down, so that the storage process of the drill pipe between the drill floor and the ground requires the cooperation of multiple devices. This processing method will not only reduce the automatic processing efficiency of drill pipes and affect the cycle, but also increase the risk of safe operation of the system when multiple equipments are operated together.
