Abstract

The invention belongs to the technical field of coal mine underground development equipment, and particularly relates to a large-section groove-shaped channel straddle type drill carriage. The straddle type drill carriage comprises a machine body part, four onboard jumbolters, four drill arms, a guard plate part, two sets of lifting operation platforms, an electrical system and a hydraulic system; and the machine body part is arranged below the guard plate part, the four onboard jumbolters are arranged at the front ends of the four drill arms correspondingly, the four drill arms are divided into a front area, a rear area, a left area and a right area to be symmetrically arranged above the machine body part, the guard plate part is installed in the middle of the upper portion of the machine body part, and the two lifting operation platforms are arranged on the rear end face of the machine body part in a bilateral symmetry mode, the electric system is installed on the right front side of the machine body part, and the hydraulic system is installed on the right rear side of the machine body part. The straddle type drill carriage has the advantages that collision between a unit and a belt conveyor or the roadway is avoided, and unsafe accidents are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of underground development equipment in coal mines, and in particular relates to a straddle drilling vehicle with a large cross-section groove-shaped passage. Background technique [0002] At present, most coal mine roadways use pneumatic bolting rigs, or use single-body bolting rigs, or install temporary support and bolting rig devices on the roadheader for bolting. The support mode of the rock bolter is labor-intensive, the support area is small, and the safety is poor; the mode of the single-bolt drill car for support is frequently alternated and wrong, the construction process is complicated, and there are many safety hazards; The mode of installing temporary support and bolting device for support is still in the exploratory stage due to the large size of the bolter, complex structure, and poor roadway adaptability. In summary, these operating modes There are problems such as serious unbalance of excava...
