Automatic drill pipe mounting and dismantling device and engineering drilling machine

Abstract

Provided are an automatic drill pipe mounting and dismantling device and an engineering drilling machine. The drill pipe mounting and dismantling device includes a drilling machine base, a drilling machine platform rotatably arranged on the drilling machine base, a drill pipe tray, a tray lifting mechanism and a tray inclination angle adjusting mechanism, wherein the drilling machine platform is provided with a drill pipe to be mounted or dismantled, a pusher and a mounting and dismantling drill pipe transfer channel for transferring or moving out the mounted or dismantled drill pipe. The traylifting mechanism drives the drill pipe tray to transfer the mounted or dismantled drill pipe to be or from between the drill pipe to be mounted or dismantled and the pusher. The tray inclination angle adjusting mechanism includes a telescopic push rod with the two ends rotatably connected with the drilling machine base and the drill pipe tray respectively, the telescopic push rod drives the drill pipe tray to rotate, so that the inclination angle of the mounted or dismantled drill pipe is matched with the inclination angle of the drill pipe to be mounted or dismantled and the inclination angle of the pusher. The problem that the free end of a rocking arm of an existing engineering drilling machine has a high load and is damaged easily, the thrust and stroke length of a bracket adjustinghydraulic cylinder are limited, exploiting work can only be performed on an inclined coal layer with a small inclination angle, and the application range of the drill pipe mounting and dismantling device is limited are solved. The automatic drill pipe mounting and dismantling device has the advantages of being simple in structure, high in drill pipe mounting and dismantling efficiency and precise,and the posture of the drill pipe including the drill pipe tray can be adjusted randomly flexibly according to the design length of a hydraulic telescopic push rod.

Description

technical field [0001] The invention relates to the technical field of engineering drilling rigs, in particular to an automatic drilling rig loading and unloading device and an engineering drilling rig with an automatic drilling rig loading and unloading device, in particular to a coal mining rig for sidewall mining in open-pit mines. Background technique [0002] During the construction of engineering drilling rigs, especially for the mining of inclined coal seams in open-pit mines, the engineering drilling rig itself needs to be fixed to provide back support for the advancement of the drill bit. In order to save construction time and avoid frequent movement of the drilling rig, it is necessary After advancing the length of a drill rod, the propeller and the drill rod are separated and the drill rod is lengthened to continue drilling. [0003] The drill pipe that engineering drilling rig adopts in the prior art, as Figure 9 As shown, it includes a first drill rod 101 to be...

AI Technical Summary

Problems solved by technology

[0007] Therefore, the technical problem to be solved by the present invention is to overcome the relatively large load at the free end of the rocker arm of the engineering drilling rig in the prior art under the premise of solving the problem that the drilling rig needs to separately occupy the construction passage space outside the drilling rig to transport the drill pipe. It is easy to be damaged, and the thrust and stroke length of the bracket adjustment hydraulic cylinder are limited, and only the inclined coal seam with a small inclination angle can be mined. An automatic drilling rod loading and unloading device is provided, the automatic drilling rod loading and unloading device includes:
