[0037] The applicant's research found that:

[0038] The related integrated top anchoring mechanism for anchoring and drilling has the following problems during construction: For a long time, due to the limited tunnel space size or body size of the anchoring and drilling machine, the anchoring range of the top anchoring mechanism has also been greatly limited, and certain requirements have been placed on the tunnel height. The anchoring height is fixed and cannot be applied to tunnel conditions of different heights. One top anchoring mechanism can only be adapted to one machine model, resulting in low R&D efficiency and high costs; the top anchoring mechanism is fixed to the body of the anchoring and drilling machine and cannot slide left and right with the tunnel conditions. The anchoring range is relatively small. If a larger anchoring range is to be achieved, the structural dimensions will also increase; the main body of the drilling rig cannot be accurately positioned when driving the top anchor, and cannot be fine-tuned or the fine-tuning range is small, making it difficult to apply to complex construction conditions. Therefore, the present invention provides a top anchoring mechanism for an integrated anchoring and drilling machine that overcomes the deficiencies and shortcomings of existing top anchoring mechanisms, can provide anchoring in a large width, at multiple angles, and over a large range, is more efficient, and is more adaptable to the construction of efficient mining in different tunnel conditions, especially for low-type tunnels.
