Abstract

The invention relates to the field of coal mine underground roadway digging, in particular to an anchor rod drill carriage integrating coal mine digging, supporting and transportation parallel fast operation. The anchor rod drill carriage solves the problems of complexity and time waste of the existing machine debugging process, low roadway digging efficiency, digging and supporting unbalance and the like. A middle frame is of an arc-shaped structure, belt conveyor pin tooth transmission traction mechanisms connected with a mine traction type self-adaptive belt conveyor are symmetrically arranged at the two sides of the middle frame, and the mine traction type self-adaptive belt conveyor passes through an arc-shaped space below the middle frame and extends to a position under a digging machine discharging part; eight sets of drill arms are matched, respectively include four sets of front anchoring and protecting drill arms, two sets of back anchoring and protecting drill arms and two sets of side upper anchoring and protecting drill arms, and are arranged in three rows at the front side and the back side, in addition, each set of drill arms can slide for a certain displacement stroke, the adjustable supporting ranging distance height can be realized, 6-top 2-upper anchor rod supporting can be completed in one step through parallel operation, the supporting time is shortened, the supporting efficiency is improved, a belt conveying passage can be provided, and the one-supporting and one-conveying operation parallel operation can be realized.

Description

technical field [0001] The invention relates to the field of coal mine underground roadway excavation, in particular to a bolter drilling vehicle for parallel and rapid operation of coal mine excavation, support and transportation. Background technique [0002] With the gradual expansion of the scale of the mine, the excavation efficiency is low, and the contradiction between mining and excavation is becoming increasingly prominent. The tension in production has become a prominent problem restricting the mine's increase in production and capacity expansion. Management is also stressful. [0003] The traditional continuous mining production process adopts double-lane excavation, the method of excavation first and support later, and production and support cannot be carried out at the same time. During the double-lane excavation process, the equipment needs to be turned back and forth, which not only wastes the excavation time, but also increases the safety hazards in the prod...
