A top bolt drilling rig and a top bolt drilling rig comprising the same

Abstract

The invention discloses an anchor rod jacking mechanism which comprises a fixing mechanism, a supporting mechanism, a sliding block and a drill box mechanism. The fixing mechanism comprises a base, a stand plate and a connecting seat. Protrusions for fixing guide blocks are arranged on the stand plate. The supporting mechanism and the sliding block are in sliding connection with the opposite side faces of the stand plate through the guide blocks respectively. One end of the supporting mechanism and one end of the slide block are connected with base through telescopic oil cylinders. The drill box mechanism comprises a bottom frame and two independent drill box sliding seats. The bottom frame is connected with the base, and the drill box sliding seats can horizontally move along the bottom frame. When the drill box sliding seats move to the sliding block, the drill box sliding seats can be connected with the other guide rail face of the sliding block and slide along the sliding block. The invention further discloses an anchor rod jacking drilling carriage with a drilling machine. The anchor rod jacking drilling carriage comprises a four-wall anchor rod jacking drilling carriage body and a six-arm anchor rod jacking drilling carriage body. The drilling machine in the anchor rod jacking drilling carriage can work at the same time. Fast supporting operation on a top plate can be achieved, the structure is compact, and multiple functions are achieved. The anchor rod jacking mechanism and the anchor rod jacking drilling carriage operate in cooperation with heading equipment to complete the supporting and transferring function synchronously, operating personnel are greatly reduced, the labor intensity is lowered, and the supporting efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of coal mine underground support, in particular to a top-bolt drilling rig and a top-bolt drilling vehicle comprising the drilling 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.

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
