Side bolt drilling machine and side bolt drilling carriage with same

Abstract

The invention discloses a side bolt drilling machine which comprises a fixing mechanism, a supporting mechanism, a sliding rack, a drilling box mechanism and a cartridge conveying box. The fixing mechanism comprises a base, a vertical plate and a connecting seat. Protrusions for fixing guide blocks are arranged on the vertical plate. The supporting mechanism and the sliding rack are in sliding connection with the opposite side faces of the vertical plate respectively through the guide blocks, and one end of the supporting mechanism and one end of the sliding rack are connected with the base through a telescopic oil cylinder. The drilling box mechanism comprises a bottom rack and two independent drilling box sliding seats. The bottom rack is fixedly connected with the base, the drilling box sliding seats can horizontally move along the bottom rack, and when the drilling box sliding seats move to the sliding rack, the drilling box sliding seats can be connected with the other guide rail face of the sliding rack and slide along the sliding rack. The cartridge conveying box is used for completing the automatic cartridge feeding procedure of the drilling machine. The invention further discloses a side bolt drilling carriage with the drilling machine. By means of automatic cartridge feeding and automatic anchor bolt mounting, mechanization and automation of anchor bolt supporting work are achieved, the construction needs of a plurality of rows of side bolts can be met, and the side bolt drilling carriage works in cooperation with heading equipment to synchronously complete side bolt supporting and transferring functions.

Description

technical field [0001] The invention relates to the technical field of coal mine underground support, in particular to a gang bolter drilling rig and a gang bolter including the drill rig. Background technique [0002] The unbalanced state of anchor excavation in my country's coal mines is relatively serious, and the support speed cannot keep up with the excavation speed, which has become a bottleneck restricting the development of rapid excavation technology. In the roadway excavation operation, the operating rate of the roadheader is only about 30%, and most of the rest of the time is used for support. The low support efficiency is the most important factor affecting the excavation footage. [0003] At present, most of the bolt and cable support operations in large and medium-sized coal mines in my country rely on manual use of hand-held single bolters and coal electric drills, while the single-piece bolter has low mechanization and high labor intensity. And because the h...

In the roadway excavation operation, the operating rate of the roadheader is only about 30%, and most of the rest of the time is used for support. The low support efficiency is the most important factor affecting the excavation footage

[0003] At present, most of the bolt and cable support operations in large and medium-sized coal mines in my country rely on manual use of hand-held single bolters and coal electric drills, while the single-piece bolter has low mechanization and high labor intensity.

And because the hand-held single bolter is operated by manpower, the limitation of manpower itself causes the locking force of the bolt to be tightened twice, which not only increases the workload, but also takes up a lot of time, and requires workers to work in groups. Hence the inefficiency of monobloc rock bolters
