Drill carriage device for intelligently and automatically feeding drill rods for coal mine

Abstract

The invention relates to a drill carriage device for intelligently and automatically feeding drill rods for a coal mine. The drill carriage device comprises a main machine body, a working mechanism provided with the drill rods, a drill rod box for storing the drill rods, a drill rod conveying frame, crawler walking devices and a mechanical arm, wherein the crawler walking devices are fixed to thetwo sides of the main machine body, make contact with the ground and are used for moving the main machine body; the drill rod box is arranged on the main machine body, and the drill rod conveying frame is arranged below the drill rod box; the drill rod box comprises a frame body, and a front supporting seat and a rear supporting seat which are the same in structure are arranged on the front side and the rear side of the frame body respectively; and the drill rod conveying frame comprises an inner frame and a lifting table, the lifting table is arranged on the inner frame and comprises a plurality of lifting frames arranged in parallel, the lower portion of the lifting table is connected with a third lifting oil cylinder, and the third lifting oil cylinder is connected with a second propelling oil cylinder. The drill rod box conveys the drill rods out from the lower portion, the top face can be closed, the situation that impurities fall into the drill rod box and affect conveying of thedrill rods is avoided, and therefore the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine drilling rigs, in particular to an intelligent automatic drilling rig device for coal mines. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below ground and related facilities. Coal mines are excavated by humans The reasonable space excavated in the geological layer rich in coal usually includes roadways, shafts and mining faces, etc. When drilling coal mines, a drilling rig is used. The drill bit on the drilling rig is driven by power. The output turns and drills the co...

Problems solved by technology

[0003] The existing drilling rig is equipped with a drill pipe box for storing drill pipes. The drill pipe is grabbed to the designated position by the mechanical arm installed next to the drill pipe box, and then another mechanical arm is used to grab the drill pipe to the working position. During the entire operation process, the inability to automatically load the rod reduces work efficiency; and the problems caused by such a rod loading process are: (1) The top surface of the drill pipe box is required to be open to facilitate the mechanical arm to grab the drill pipe, but the drill The top surface of the rod box cannot be closed. When working in the coal mine, impurities such as coal often fall into it and get stuck between the drill pipes, affecting the grasping of the drill pipes; (2) The arrangement of the two mechanical arms has requirements for the height of the site , limited use in coal mines
