Problems solved by technology

Using manual supplementary anchoring can not realize synchronous parallel operation, the labor intensity of workers is high, and the efficiency is low
If an ordinary bolter is used for support and anchor support, the bolter has four or six drill frames, but most of the drill frames are top-anchor drill frames, and only two drill frames can repair the anchor and support the anchor operation. low efficiency

Abstract

The invention provides an anchor bolt support construction device. The device comprises a base, a first anchor bolt assembly located on the front side of the base and a second anchor bolt assembly located on the rear side of the base, wherein drilling frames in the first anchor bolt assembly and the second anchor bolt assembly can be used for conducting side anchor support operation and roof anchor support operation before and after rotation. According to the anchor bolt support construction device and a crawler-type multi-arm side anchor bolt jumbo applying the same, support construction of multiple side anchors can be conducted at the same time, so that the side anchor support speed is increased, and the problem that the side anchor support efficiency is relatively low under the condition that the roof and side conditions are relatively good and the roof anchor support is completed is solved; and part of the drilling frames can rotate to replenish and drive roof anchors, so that the application range of the anchor rod support construction device is widened, and the requirements of various working conditions can be met.

Description

technical field [0001] The invention relates to the technical field of downhole support, in particular to a rock bolt support construction device and a crawler-type multi-arm rock bolt drilling rig. Background technique [0002] At present, most coal mine roadway excavation in China adopts the form of bolt support, and many modern coal mines gradually use bolters to replace manual anchor drilling operations, and basically realize mechanized anchor protection operations. The emerging rock bolt models include two-arm rock bolt and multi-arm rock bolt, which can basically realize the support operation of top and side bolts, and meet the needs of coal mine roadway excavation to a certain extent. [0003] For mines with general geological conditions, under the condition of ensuring a certain empty head distance, top anchor and side anchor support are carried out at the same time. However, in some mines with better roof and floor conditions, the bolter follows the excavation equi...
